Description

Technical Field

[0001] This utility model relates to an antifreeze system for a water tank valve on a dust suppression vehicle, comprising an air compressor, a high-pressure air inlet pipe, a water tank, a temperature sensor, a water tank outlet pipe, a water valve, a spray pipe, and a controller. Its key feature is that when the controller receives information from the temperature sensor indicating that the ambient temperature is below 0°C, it controls the water valve to open, controls the air compressor to operate and generate compressed air, and injects the compressed air into the water tank through the high-pressure air inlet pipe. The compressed air in the water tank then discharges residual water from the water valve and spray pipe through the spray pipe. After the residual water is discharged, the controller controls the air compressor to shut off and controls the water valve to close, thereby achieving the purpose of antifreeze. This system belongs to the field of automatic control technology. Background Technology

[0002] Application number 202010545717.X discloses an antifreeze water system for a sweeper truck, which improves the antifreeze capability of the water system by adjusting the mixing ratio of antifreeze and clean water at different ambient temperatures. Because different vehicle models have different antifreeze requirements, this technology is not suitable for the antifreeze requirements of the water tank valves in dust suppression trucks. Summary of the Invention

[0003] To address the shortcomings and defects of existing technologies, this utility model relates to an antifreeze system for a water tank valve in a dust suppression vehicle, comprising an air compressor, a high-pressure air inlet pipe, a water tank, a water tank outlet pipe, a water valve, and a spray pipe. Its key feature is that it further includes a temperature sensor, a controller, and a liquid level sensor. The controller is equipped with an automatic execution control program. When the controller receives information from the temperature sensor indicating that the ambient temperature is below 0°C, the automatic execution control program is triggered, controlling the water valve to open and the air compressor to operate and generate compressed air. The compressed air is injected into the water tank through the high-pressure air inlet pipe, and the compressed air in the water tank then condenses on the water valve and the spray pipe. The residual water is discharged through the spray pipe. When the level sensor detects that the residual water in the tank has been completely discharged, the automatic execution control program in the controller is triggered. The controller controls the air compressor to shut down and the control water valve to close. The connection method is as follows: one end of the high-pressure air inlet pipe is connected to the air compressor, and the other end of the high-pressure air inlet pipe is inserted into the water tank. The temperature sensor is placed on the outer surface of the water tank. One end of the water tank outlet pipe is inserted into the bottom of the water tank, and the other end of the water tank outlet pipe is led out from the top of the water tank and connected to the water valve. The other end of the water valve is connected to the spray pipe. The level sensor is connected to the controller and is located inside the water tank.

[0004] Furthermore, the controller is connected to the switch of the air compressor to control the operation and shutdown of the air compressor.

[0005] Furthermore, the controller is connected to the electronic switch of the water valve to control the opening and closing of the water valve.

[0006] Furthermore, the controller is connected to the vehicle battery and is either in a constant-power state or has an internal power supply.

[0007] This utility model relates to an antifreeze system for a water tank valve on a dust suppression vehicle, comprising an air compressor, a high-pressure air inlet pipe, a water tank, a temperature sensor, a water tank outlet pipe, a water valve, a spray pipe, and a controller. Its key feature is that when the controller receives information from the temperature sensor indicating that the ambient temperature is below 0°C, it controls the water valve to open, controls the air compressor to operate and generate compressed air, and injects the compressed air into the water tank through the high-pressure air inlet pipe. The compressed air in the water tank then discharges residual water from the water valve and spray pipe through the spray pipe. After the residual water is discharged, the controller controls the air compressor to shut off and controls the water valve to close, thereby achieving the purpose of antifreeze.
