The invention provides an explosion-proof watering cart. The explosion-proof watering cart comprises a front frame, a rear frame, an engine exhaust pipe, a waste gas treatment box, a water tank and awater tank heating device, wherein the water tank heating device comprises a plurality of gas conveying pipes for conveying gas, a gas bag which is fixedly arranged on the cart and is used for containing pressure gas, a first pneumatic butterfly valve and a second pneumatic butterfly valve which are used for selecting a moving path of hot waste gas output by the engine exhaust pipe, a waste gas heating pipe for heating water in the water tank when needed, and an electric control assembly for automatically controlling the first pneumatic butterfly valve and the second pneumatic butterfly valveto do corresponding actions according to the environment temperature and the water level in the water tank so as to select the moving path of the hot waste gas; and the electric control assembly comprises an electromagnetic gas valve for selecting the moving path of the waste gas, a temperature sensor and a liquid level sensor for detecting the water level of the water tank. According to the explosion-proof watering cart, the manufacturing and utilization cost is low under the condition that the explosion-proof requirements of a coal mine are met; and the hot waste gas can be automatically andeffectively utilized according to requirements so that the condition that the water in the water tank is frozen and the normal watering utilization is influenced is prevented.

    本发明提供一种防爆洒水车,包括前车架、后车架、发动机排气管、废气处理箱、水箱以及水箱加热装置,水箱加热装置包括用于输气的若干根输气管,固定设于车上用于盛装压力气体的气包,用于执行对发动机排气管输出的热废气走向路径进行选择的第一气动蝶阀和第二气动蝶阀,用于需要时对水箱内的水进行加热的废气加热管,以及用于根据环境温度和水箱内的水位自动控制第一和第二气动蝶阀相应动作从而选择热废气走向路径的电控组件,电控组件包括执行废气走向路径选择的电磁气阀、温度传感器和检测水箱水位的液位传感器。本发明在满足煤矿防爆要求的前提下,制造和使用成本低,能根据需要自动有效地利用热废气防止水箱内的水结冰影响正常洒水使用。
