Waterway system antifreezing device of fire vehicle

Abstract

The invention provides a freeze preventing device in the waterway system of a fire engine, which is mainly applied on fire engines. The freeze preventing device includes a water tank, a water pump, a water pumping pipeline between the water pump and the water tank, and a control valve, a fire monitor body, and a fire hose arranged on the water pumping pipeline. The rotating shaft of the water pump is connected with the output shaft of the engine of the fire engine by a power taker, a water pipe is connected between the outlet of the water pump and the inlet of the fire monitor body, a control valve is arranged on the water pipe, the water pipe between the outlet of the water pump and the control valve is connected with the fire hose. The freeze preventing device also includes an air compressor arranged on the vehicle body, and an air compressing control valve serially connected on the outlet pipeline. The air compressing control valve is communicated with the cavity chamber of the water pump through a pipeline, a heat-preserving drainage valve which is heated by the electricity provided by a vehicle battery is arranged on the bottom of the water pump. The freeze preventing device in the waterway system of a fire engine of the invention can prevent the fire engine hose and the fire monitor body from being frozen, and ensures that the hose and the fire monitor can be used normally during low-temperature severe cold.

Description

technical field [0001] The invention relates to a fire truck, in particular to an antifreeze device for a waterway system of a fire truck. Background technique [0002] When the northern winter is in an extremely cold environment below minus 10°C, fire trucks often suffer from freezing of the waterway system at the fire scene. Once this happens, it will seriously affect the fire fighting ability of the fire truck until it completely loses its combat effectiveness. In order to solve this problem Some firefighters use hot air blowers to thaw the frozen parts of the water system of fire trucks. However, this solution is relatively passive and must be solved only when the above-mentioned situation occurs, and it cannot be effectively prevented. Contents of the invention [0003] The object of the present invention is to provide an antifreeze device for the waterway system of the fire truck, which can prevent the waterway system of the fire truck from freezing and enable the fi...
