Description

Electric street sweeper with improved collection performance

The present invention relates to an electric sweeper that cleans the road while inhaling various kinds of trash from the road surface, and more specifically, three cyclone dust collectors are connected in a series structure so that the trash sucked by the suction device is sequentially installed by three cyclone dust collectors. The present invention relates to an electric cleaning vehicle with improved dust collection performance.

Each local government or agency that manages roads regularly carries out cleaning work to keep the road surface clean by collecting garbage that has fallen on roads that are already being built and used.

Road cleaning requires a large amount of manpower and time due to its large cleaning area, as well as a high risk of accidents due to the high risk of accidents due to the fact that the work is performed in a situation where vehicles are running around the vehicle (hereinafter referred to as ``cleaning car'' ') is used to perform cleaning work.

On the other hand, conventionally, a sprinkling type cleaning car and a vacuum suction type cleaning car have been used.

The sprinkling-type cleaning vehicle has the advantage of preventing dust from scattering by spraying water onto the road surface during cleaning, and effectively removing fine dust from the road surface, but it cannot be used in winter, and a large amount during cleaning work. It uses water, and has the disadvantage of having to replenish water frequently.

The vacuum suction-type cleaning car is a cleaning vehicle that performs cleaning while inhaling garbage or dust from the road by using the suction power generated by the operation of the blower. Although the removal efficiency of fine dust is lower than that of the sprinkling-type cleaning vehicle, it is used in all seasons. Since this is possible, it has the advantage of enabling effective operation of the cleaning vehicle.

The vacuum suction type cleaning vehicle is configured to operate the blower with the power generated from the auxiliary engine by mounting a separate auxiliary engine for the operation of the blower, or a part of the power generated from the vehicle engine through the engine power take-off device to the blower. It is configured to operate the blower by delivering it.

However, the method of operating the blower by the auxiliary engine has a problem in that soot and noise are generated due to the operation of the auxiliary engine, and the maintenance cost (oil cost, oil exchange cost, etc.) increases due to the auxiliary engine.

In addition, the method of operating the blower by the engine power take-off device not only requires cumbersome operation by the driver, but also has a very complex structure, and when power is withdrawn during the driving process of the vehicle, the transmission system of the vehicle is stressed. There is a problem that causes a malfunction.

In addition, the auxiliary engine or the engine power take-off device is a method suitable for a cleaning vehicle based on a large truck, and has a disadvantage that is not suitable for a small cleaning vehicle that is easy to clean in an urban area or narrow road where vehicle traffic is busy.

On the other hand, in consideration of the air pollution problems caused by noise or smoke generated when the auxiliary engine is operated, there is an increasing demand for electric road cleaners that operate blowers using electric motors, but based on small trucks of 1 ton or less. In the case of a cleaning vehicle, it is not easy to secure a space for installing a large-capacity electric motor, and thus there is a problem in that the dust collection performance is relatively deteriorated because the size of the electric motor that can be installed is limited.
