Intelligent air blowing and drainage antifreeze system for washing and sweeping cars

Abstract

The invention discloses an intelligent blowing draining antifreeze system for a cleaning and sweeping vehicle. The intelligent blowing draining antifreeze system comprises chassis air sources, a chassis distributing valve, an air compressor, an unloading valve, an air drier, air storage tanks, pneumatic high-pressure ball valves, electromagnetic water valves, a high-pressure water pump, a water filter, a DC water pump and corresponding pipelines, wherein the two air sources respectively inflate the two air storage tanks, a pneumatic system, a high-pressure water path system and a spraying dust-reducing system are organically combined together, and an electrical control system controls the pneumatic system to perform intelligent blowing drainining tasks on the high-pressure water path system and the low-pressure spraying dust-reducing system. According to the intelligent blowing draining antifreeze system for the cleaning and sweeping vehicle, accumulated water in parts and components and the pipelines of the cleaning and sweeping vehicle can be drained away, and the drained accumulated water can be recovered, so that freezing of the accumulated water on pavements is avoided, and the cleaning and sweeping vehicle can normally work under the environment of being lower than 0 DEG C.

Description

technical field [0001] The invention relates to an intelligent air blowing and drainage antifreezing system, in particular to an intelligent air blowing and drainage antifreezing system for washing and sweeping vehicles. Background technique [0002] At present, urban road cleaning operations have basically realized the mechanized operation mode, which is completed by special vehicles for road cleaning operations. Due to the dry and cold winter, especially in the north, it is easy to raise dust and there is a lot of dust on the road surface. It is necessary to wash and sweep the road surface to keep the urban environment at a better level. However, it is inconvenient for current cleaning vehicles to perform cleaning operations when the temperature is lower than 0°C, because in this environment, after the vehicle operation is completed, although the ball valve can be opened to drain the water in the low-pressure water pipe and the tank, the high-low pressure water spray The ...

Problems solved by technology

[0003] Existing anti-freeze technology for drainage only has the function of blowing air to the high-pressure water pump alone. This function can only drain the residual water in the high-pressure water pump, but does not carry out other related components such as water filter and DC pump and their corresponding pipelines. Air blowing and drainage cannot rule out the possibility that the pipeline and these components may be affected by the freezing or even freezing of accumulated water when the temperature is lower than 0°C, which may affect the normal operation of the washing machine; in addition, the discharged accumulated water has not been recycled, which may lead to ice on road
