Wall space cleaning vehicle high-pressure water pump protector

Abstract

The invention discloses a wall space cleaning vehicle high-pressure water pump protector which comprises a controller, a detecting switch (4) and a water level detecting mechanism, wherein the water level detecting mechanism is arranged in a water tank; a tensioning wheel component (3) are mounted on a tensioning wheel mounting rack (5) through a swing arm; the detecting switch (4) is fixedly mounted on the tensioning wheel mounting rack (5) and directly faces the end face of the swing arm of the tensioning wheel component (3); and the controller is connected with the detecting switch (4), thewater level detecting mechanism and a secondary engine. The wall space cleaning vehicle high-pressure water pump protector has the water lacking protective function, can realize separate control, andstarts the secondary engine to carry out normal operation on the premise of preventing a high-pressure water pump from idling.

Description

technical field [0001] The invention relates to a protection device, in particular to a protection device for a high-pressure water pump of a wall cleaning vehicle, which belongs to the technical field of engineering vehicles. Background technique [0002] The wall cleaning vehicle is a special vehicle, which is used to clean wall structures such as culvert walls and expressway windshields. The wall cleaning vehicle usually includes a cleaning robot arm device with a rolling brush device and a scouring device with a high-pressure water pump. When the cleaning robot arm device performs the rolling operation, the scouring device performs water spraying operation at the same time to realize the washing of the wall. [0003] The cleaning mechanical arm device of the wall cleaning vehicle is usually controlled by the auxiliary engine driving the hydraulic pump, and the flushing device is usually controlled by the auxiliary engine driving the high-pressure water pump through the t...

AI Technical Summary

Problems solved by technology

However, under conditions such as rainy days or freezing weather in winter, the wall cleaning vehicle generally only needs to control the cleaning mechanical arm device to work, and does not need to control the flushing device, because the cleaning mechanical arm device is driven by the auxiliary engine to drive the hydraulic pump. Control, while the wall cleaning vehicle with water shortage protection function cannot achieve independent control because it prevents the auxiliary engine from starting in the water shortage state
