[Abstract]:With the rapid development of economy and the accelerating process of urbanization, people's demands on their own living environment are constantly improving, and the development of urbanization makes the number of public places such as office areas, factories and other public places grow rapidly. The problem of sanitation cleaning is becoming more and more serious. In order to reduce the labor intensity of cleaning workers and improve the working efficiency, sanitation cleaning work has begun to use road cleaning machinery. However, most of the existing road cleaning equipment in China is refitted from the second class chassis of truck, driven by internal combustion engine, large volume and mass, inflexible, noise, serious exhaust gas emission problem, hydraulic pump is used to drive the operating device. Pipeline system is complex, hydraulic oil leakage problem is prominent, based on the above problems, the development of pollution-free, light and flexible operation. The simple electric road cleaning equipment driven by the operating device has important practical significance. This paper takes the pure electric suction vehicle as the research object, by comparing the existing basic configuration of the suction car at home and abroad. This paper puts forward the basic structure of the chassis of pure electric suction vehicle. Through the research on the cleaning mechanism and garbage suction mechanism, the brush cleaning system and the dust and dust scavenging gas path system are designed. The hydrodynamic simulation and optimization of suction nozzle and gravity settling chamber are carried out. The main work of this paper is as follows: firstly, according to the application environment of pure electric suction sweep vehicle, the overall structure is designed. The whole vehicle is divided into five systems: chassis driving system, brush cleaning system, dust and dust removal system, electrical control system and the whole vehicle power system. In this paper, a two-axis and four-axis driving system with driving motor and working motor is put forward, especially the single-end input double-end output drive device is designed for the working motor, and the driving motor is driven to the operating motor. The parameters of the working motor and the whole vehicle power supply system are calculated and the corresponding parameters of each system are obtained. Secondly, on the basis of the research on the cleaning mechanism of the disk brush cleaning system, the basic structure of the disk brush system, the lifting electric push rod and the obstacle avoidance spring are designed and matched, and the corresponding design parameters are obtained. The 3D structure model of brush system is established according to the parameters. Finally, on the basis of the research on the mechanism of dust collection, the system of circulating dust collection gas path is designed, and the simulation optimization of the suction nozzle and gravity settling chamber is carried out by using the hydrodynamic simulation tool Fluent. The purpose of this paper is to reduce the energy consumption of the gas path system, to improve the performance of dust collection, and finally to obtain suction nozzles and gravity settling chambers with higher dust collection efficiency and lower energy consumption. On the basis of summing up the latest research work of pure electric road cleaning vehicle at home and abroad, this paper designs the driving system structure of the whole vehicle, and focuses on the simulation optimization of the circulating dust and dust removal system. This research has certain guiding significance for the research and development of pure electric suction car.
