Dust collection device of engine compartment of motor vehicle

Abstract

The invention provides a dust collection device of an engine compartment of a motor vehicle, and relates to the technical field of dust collection equipment. The dust collection device of the engine compartment of the motor vehicle comprises an enclosed hood, a telescopic driving piece and a shear-type telescopic structure, wherein the closed hood is installed at the top end of the shear-type telescopic structure, one end of the telescopic driving piece is fixed in position, and the other end of the telescopic driving piece is connected with the portion between the top end and the bottom end of the shear-type telescopic structure. The telescopic driving piece can stretch out or draw back. The closed hood can be driven by the shear-type telescopic structure to lift or fall, and is used forclosing the engine compartment of the motor vehicle when being in butt joint with an opening of the engine compartment of the motor vehicle. By means of the dust collection device, the technical problems in the prior art are solved that when the engine compartment is at a high position, a larger reciprocating motion range of a lifting hydraulic cylinder is needed, the requirements for output pressure of the hydraulic cylinder and the moving stroke of the hydraulic cylinder are both high, and the special hydraulic cylinder needs to be adopted, resulting in high cost of a lifting assembly.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a dust removal device for a motor vehicle power compartment. Background technique [0002] Power compartments such as electrical compartments of motor vehicles such as electric buses and electric trucks are usually arranged at the tail. During the daily driving of a motor vehicle, the power compartment arranged at the rear of the vehicle is very easy to accumulate dust. Since too much dust in the power compartment will cause damage to the electrical appliances or the internal combustion engine in the power compartment, it is necessary to regularly remove dust from the power compartment of the electric bus. [0003] An existing device for removing dust from a power compartment of a motor vehicle includes a nozzle, a mechanical arm, a dust cover and a dust collector. Wherein, the nozzle is communicated with the high-pressure gas, and the nozzle is installed on the ...

AI Technical Summary

Problems solved by technology

[0005] However, when the power cabin is at a higher position, in order to be able to drive the dust collecting cover to the position opposite to the position of the power cabin, the reciprocating range of the lifting hydraulic cylinder needs to be larger, so the existing motor vehicle power cabin dust removal device is not only for the hydraulic cylinder The output pressure requirements of the hydraulic cylinder are relatively high, and the requirements for the moving stroke of the hydraulic cylinder are also relatively high. It is necessary to use a special hydraulic cylinder, such as a plunger hydraulic cylinder, resulting in a higher cost of the lifting component.
