One-key drainage system of environmental sanitation vehicle and control method thereof

Abstract

The invention discloses a one-key drainage system of an environmental sanitation vehicle and a control method thereof, only a chassis air source is adopted for air supply, air storage and pressurization are conducted through an auxiliary air tank, the number of air sources is reduced, cost and installation space are saved, an air path is divided into two paths after passing through a pressure reducing valve, and one path is used for air blowing and drainage; and the other path is conveyed into the air control box for controlling the opening or closing of a plurality of pneumatic elements in the pneumatic system, so that the multifunctional application of a single air source is realized, the structural design of the air path system is simplified, the on-off of the blowing drainage air pathis controlled by controlling the opening or closing of the electromagnetic air valve, and the control of the pneumatic system is not influenced. Absolute isolation of a gas path and a water path is achieved by pushing the water path ball valve through the air cylinder, and the situation that the pneumatic system is reversely broken down by the water path due to valve failure is avoided. Moreover,the whole air blowing and water draining operation process is controlled by an electric control system to be automatically executed, a valve does not need to be manually operated, the one-key water blowing function is achieved, and the intelligent degree is high.

Description

technical field [0001] The present invention relates to the technical field of air blowing and drainage for sanitation vehicles, in particular to a one-key drainage system for sanitation vehicles, and in particular to a control method for the above-mentioned one-key drainage system for sanitation vehicles. Background technique [0002] At present, almost all sanitation vehicles (cleaning vehicles, sweeping vehicles, trash can cleaning vehicles / stations, snow removal vehicles and dust suppression vehicles, etc.) have the problem of freezing water pipes, water pumps or water valves during winter operations. , so every time the operation is completed, the remaining water in the waterway needs to be drained to ensure the safety of the waterway system on the vehicle. [0003] In the conventional water blowing scheme, the outlet (high pressure) and inlet (low pressure) of the high-pressure water pump are connected through a pneumatic ball valve or an electromagnetic valve, which w...

Problems solved by technology

[0004] The invention provides a one-button drainage system and its control method for sanitation vehicles to solve the problem that in the current air blowing and drainage scheme, the pneumatic components are prone to failure due to long-term immersion in water, which may cause the water system to reversely rush into the bodywork pneumatic system Even the technical problems of the chassis air circuit
