Anti-explosion sprinkling truck

Abstract

Provided is an anti-explosion sprinkling truck, comprising a front frame, a rear frame, a main water tank, a waste gas treatment device, a water pump, and a water pump control system. The water pump control system comprises a hydraulic pump, a hydraulic motor, a filter, an overflow valve, a hand-operated direction valve, and a fuel tank. The oil outlet of the hydraulic pump is connected with the oil inlet of the overflow valve and the oil inlet P port of the hand-operated direction valve. The hydraulic motor drives the water pump to operate. The water pump control system also comprises a water pump solenoid valve, an explosive-proof power supply, and a liquid level switch. The execution port A port of the hand-operated direction valve is connected with the oil inlet P port of the water pump solenoid valve. The execution port A port of the water pump solenoid valve is connected with the oil inlet of the hydraulic motor. The execution port B port of the water pump solenoid valve and a return port are connected with the fuel tank. The terminal of the water pump solenoid valve is connected with the explosive-proof power supply. In the connection circuit of the water pump solenoid valve and the explosive-proof power supply, the liquid level switch is connected in series. The anti-explosion sprinkling truck can prevent the water pump from idle running, and can ensure exhaust gas which is not treated not to discharge.

Description

technical field [0001] The invention relates to an explosion-proof sprinkler. Background technique [0002] An explosion-proof sprinkler is used to sprinkle water on the ground of the roadway in the coal mine. The Chinese authorized announcement number is CN203175614U. The utility model patent specification discloses a sprinkler for the coal mine. The sprinkler system uses a hydraulic motor to drive the water pump. The valve is used to control the start and stop of the hydraulic motor. When this kind of explosion-proof sprinkler is in use, the water tank often lacks water and the driver fails to find it and thus fails to close the manual reversing valve. burn out. In addition, the explosion-proof sprinkler cools and washes the exhaust gas from the engine through the exhaust gas treatment box, removes the carbon smoke and some harmful gases in the dissolved exhaust gas, and extinguishes the flame in the exhaust gas through the explosion-proof fence to ensure the safety of th...

Problems solved by technology

When there is no water in the supplementary water tank, even if the water level of the large water tank is low, no water can be filled into the small water tank, resulting in the water level of the large water tank not reaching the standard, and the exhaust gas cannot be treated

Untreated waste gas is not allowed to be discharged underground in coal mines. For this reason, the above-mentioned utility model is equipped with a water level sensor in the large water tank to feed back the water volume of the large water tank. However, the structure of the waste gas treatment tank is cumbersome, and the sewage in the large water tank It will make it difficult for the float of the water level sensor to move up and down along the measuring tube, and the measuring signal is not accurate
