Brief introduction of project resultsRiver sediment treatment can be divided into in-situ treatment and ectopic treatment. During ectopic treatment, the sediment contains a large amount of organic matter, nutrients (nitrogen, phosphorus and other nutrients) and some toxic and harmful substances such as heavy metals, pathogenic bacteria, viral microorganisms and toxic organic matter that are harmful to the ecological environment, which makes the sludge easy to stink and rot. If it is not treated in place and discharged directly into the mud pile, it is easy to cause secondary pollution to the environment. In particular, the stacking of cultivated land will affect the later restoration effect, resulting in increased difficulty in renting cultivated land. The site stacking and disposal is also indispensable, which needs huge engineering amount and high cost. The device realizes the advantages of local treatment of the sediment polluted by rivers and lakes, reducing transportation costs, reducing water pollutants from the source, reducing the subsequent treatment load, and reducing the environmental interference caused by dredging, etc., so as to solve the above problems.Performance indicatorsPolluted sediment in river channels has been cut by more than 35%, the secondary pollution of river course sediment is reduced, and the water quality of river course is ensured to remain stable. Scope of application and market prospectsIn situ desilting of polluted sediment of river channel. Ensure the long-term stable and reliable operation of urban river water conservancy projects, and improve the water quality of urban water systems and enhance the quality of river ecological environment. Investment estimatesInvestment conditions: general mechanical and electrical equipment processing and assembly.Cost: 500,000 yuan. Means of cooperationTechnology development, transaction value negotiable.

Brief introduction of project resultsThe wear resistance of high manganese steel is manifested by the deformation induced martensite of the surface structure of the workpiece when it is subjected to the impact force, that is, work hardening. The greater the impact force, the more significant the effect of work hardening, and the better the wear resistance of high manganese steel. However, the wear resistance of high manganese steel is not ideal. Inlaid hard alloy high manganese steel sledgehammer is a new type of crusher sledgehammer developed under this background. The long strip of TiC carbide is directly embedded in the striking part of the hammer in high manganese steel sledgehammer casting molding process. Thus, it not only ensures the safety of the hammer, but also significantly improves the service life of the hammer.Performance indicators(1) Adding Cr, Ti, RE, B, Nb and other alloying elements on the basis of conventional high manganese steel, the work hardening rate of high manganese steel matrix is significantly improved, and the service life of high manganese steel is significantly increased;(2) Inlaying cemented carbide in the working part of the hammer does not affect the toughness of the hammer, but also can significantly improve the wear resistance of the hammer.According to the structure of the hammer head, the cost and the degree of improvement of the service life requirements, the number of cemented carbides is determined. The maximum volume percentage can reach more than 50% of the impact site. The service life of high manganese steel hammer with cemented carbide is more than 3 times higher than that of traditional high manganese steel hammer.Scope of application and market prospectsThe weight of large hammer crushers used in cement, power and mining industries is generally more than 90 kg. Due to the large impact force and harsh working conditions, the current hammer is basically made of high manganese steel or modified high manganese steel, and other wear-resistant materials are difficult to meet the actual working conditions. Inlaid hard alloy high manganese steel sledgehammer has a very broad market prospect.Investment estimates3 to 5 million yuan.Means of cooperationTechnology transfer.

The main piston cylinder is filled with MR Shear thickening material, which has dual characteristics of magnetic sensitivity and rate sensitivity, and adopts double piston rod to realize adjustable permanent magnetic field to adapt to high frequency impact load. The secondary piston cylinder is filled with MR Plastic body, which has magnetic sensitive characteristics, and adopts excitation coil to realize continuous variable damping to adapt to the environment of different vibration excitation frequency.The magnetic control damper with high frequencyPerformance indicatorsThe secondary piston cylinder is filled with MR Plastic body, which is magnetically sensitive, and the excitation coil is used to realize continuous variable damping, so as to adapt to the vibration response of different excitation frequencies. At the same time, in view of the problem that the damping force of traditional MR Dampers is small under large amplitude and low frequency vibration, under small displacement vibration, only the main piston works, which can adapt to the high-frequency impact vibration under small amplitude; while under large displacement vibration, the main and auxiliary pistons work together, and the output of the impact dampers is significantly improved.Structurally, a half ring B is arranged in the groove opened on the outer rod of the main piston, which can better fix the MR Shear thickened sandwich round plate.Scope of application and market prospectsApplied in the field of structural vibration reduction technology, such as mechanical equipment, civil engineering, where vibration reduction devices can play a very important role.Investment estimatesSupporting hardware and software equipment, amount: 5-1 million yuan. Means of cooperationTransfer of patent.

Brief introduction of project resultsThe invention discloses a real-time road section scoring method for content routing of vehicle-mounted AD hoc network. In order to obtain the topology of Road vehicles accurately, the road section is divided into three parts, and the Road side unit (RSU) is relied on to perceive the road traffic information in real time. RSU evaluates the connectivity of the three parts of the road section respectively according to the perceived road traffic information, and obtains the overall connectivity rate of the road section from the connectivity of the three parts of the road section. Combined with road length and average road speed, the road section is scored in real time. This method can reflect the real situation of the road and provide a good support for the message routing path planning of Vehicular AdHoc Network (VANET) in an urban environment, especially the VANET routing algorithm based on road segment scoring, so as to ensure the overall optimality of the VANET routing algorithm.Performance indicatorsWe propose a real-time road segment scoring method, which defines the interface between the perception layer and the data evaluation layer, and on this basis gives the connectivity characteristics between vehicles on various modern urban roads. This method models the connectivity of vehicles on various urban roads, and gives its direct and inter-connectivity assessment. It provides a good support for the message routing path planning of vehicle-mounted AD hoc networks in urban environment. The typical routing and forwarding protocol in VANET environment is tested. The test results show that the success rate of data forwarding reaches 98% and the average forwarding delay reaches ms level, which can meet the QoE standard of users' audio and video access.Scope of application and market prospectsThis project belongs to the field of Vehicular Ad-Hoc Network, and it is a comprehensive road segment scoring method, which is suitable for urban Vehicular ad-hoc network (VANET) environment, especially for content routing planning.Investment estimates50,000 to 200,000 yuan.Means of cooperationCooperative development, technology transfer, etc.

Brief introduction of project Through the effective recovery of vehicle driving, the vibration energy in the process of people's life can be converted into electricity, and the collection and reuse of electricity in the range of 1mW-100W can be realized. It can not only effectively solve the high maintenance and renewal costs of the vehicle power supply system, reduce the safety risks and pollution risks of the internal battery power supply, but also greatly reduce the external load pressure of the vehicle power supply, effectively improving the effective range of new energy vehicles, and extending the service life of the vehicle power supply. At the same time, the industry chain of life science and technology products is derived, and the products are more daily, lightweight and portable. At present, the prototype is also formed, and provides the core technology and prototype for Japan's Mitsuha Company, and enters the market and promotes the product in Japan. At the same time, we reached cooperation intention with well-known enterprises such as SAIC Motor and Geely Automobile, and provided prototypes for them based on the strategy of independent research and development of core technologies and outsourcing of production technologies.Performance indicatorsWith the increasingly low power consumption, integration and intelligence of intelligent detection systems, there is an urgent need for a wide variety of sensors to detect a variety of vehicle environmental information. However, how to stably supply power to sensors and establish a green and low-carbon vehicle sensor integrated system has become an urgent problem to be solved. The recovery power of up to 10μW can provide power support for the radio frequency identification system, up to 100μW can supply power for the sensor. Therefore, when the output power reaches 1mW, it can achieve self-sufficiency in the power of the vehicle sensor and a variety of other small and micro electrical equipment, and if up to 1W-100W, it can be used for mobile phones, laptops and power tools.
