One-button drainage system and control method for sanitation vehicle

Abstract

The invention discloses a one-button drainage system of a sanitation vehicle and a control method thereof. Only the chassis air source is used for air supply, and an auxiliary air tank is used for gas storage and pressurization, thereby reducing the number of air sources and saving costs And the installation space, the air path is divided into two after passing the pressure reducing valve, one is used for blowing and draining, and the other is sent to the air control box to control the opening or closing of multiple pneumatic components in the pneumatic system, realizing a single air source It simplifies the structural design of the air circuit system, and controls the on-off of the blowing and draining air circuit by controlling the opening or closing of the electromagnetic air valve, while the control of the pneumatic system is not affected. The waterway ball valve is pushed by the cylinder to realize the absolute isolation of the airway and the waterway, avoiding the reverse breakdown of the pneumatic system by the waterway due to the failure of the valve. Moreover, the entire process of air blowing and drainage is automatically executed by the electronic control system, without manual operation of the valve, and the function of blowing water with one button is realized, with a high degree of intelligence.

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...
