Abstract
The utility model relates to an anti-freezing device for a fire fighting hose of a fire engine, which is mainly applied in the fire engine. The anti-freezing device comprises a water pump, a water pumping pipeline connected with the water pump and a water tank of the fire engine, a controlling valve on the water pumping pipeline, a fire fighting hose and a fire gun connected to the tail end of the fire fighting hose, wherein, a water pump outlet is connected with a water pipe, the controlling valve is installed on the water pipe, the water pipe between the water pump outlet and the controlling valve is connected with the fire fighting hose, in addition, the anti-freezing device also comprises an air compressor installed on the fire engine body and a compressed air controlling valve connected in series to the outlet pipeline, wherein, the compressed air controlling valve is mutually communicated with the chamber of the water pump through the pipeline, and an insulating drainage valve for which the electric heating is provided by a vehicle accumulator jar is installed at the bottom of the water pump. The anti-freezing device can prevent the freezing of the fire fighting hose, thus the anti-freezing device can be normally utilized.
Description
Technical field
The utility model relates to a kind of fire fighting truck, refers to a kind of fire fighting truck fire hose defroster especially.
Background technology
North of china in winter is when subzero psychro-environment below 10 ℃, the puzzlement that the water route is frozen in appears in fire fighting truck often in the scene of fire, especially the fire hose of fire fighting truck laying can begin to freeze when spraying, except water band pipeline path is reduced, resistance increases, outside jet performance is progressively lost, the fire hose that also will cause laying freezes to formalize and can't regain, in case this situation occurs, the extinguishing ability that will have a strong impact on fire fighting truck is until completely losing fighting capacity, in order to solve this predicament, having the fire fighter to adopt air-heater to freeze the position for the fire fighting truck fire hose thaws, but this kind settling mode is more passive, must can not effectively prevent just solution under the above-mentioned situation occurring.
The utility model content
The purpose of this utility model is to provide a kind of fire fighting truck fire hose defroster, and it can prevent that fire hose from freezing, and makes fire fighting truck energy operate as normal.
To achieve these goals, technical solution of the present utility model is: a kind of fire fighting truck fire hose defroster, comprise water pump, control valve on the draw water pipeline and the pipeline that draws water of connection water pump and fire fighting truck water pot, the terminal Fire branch that connects of fire hose and fire hose, exit of pump is connected with water pipe, control valve is housed on water pipe, outlet and the water pipe between the control valve at water pump are connected with fire hose, wherein also comprise air compressor that is installed on the car body and the compressed air control valve that is serially connected on its export pipeline, described compressed air control valve is connected with the chamber of water pump by pipeline, and described water pump bottom is equipped with by automobile-used accumulator jar electrically heated insulation draining valve is provided.
The utility model fire fighting truck fire hose defroster, wherein said water pot inwall is provided with foam insulation.
After adopting such scheme, the utility model water pump chamber is connected with air compressor and compressed air control valve, after the fire fighting truck fire extinguishing, turn off the control valve on the pipeline that draws water earlier, open the draining valve that connects on the water pump, the surplus water that remains in the water pump and in the water pipe connecting is run out, again water discharging valve is closed, allow air compressor work, compressed air is introduced water pump, the surplus water nozzle from Fire branch under compressed-air actuated effect that remains in the fire hose is discharged, and has therefore prevented that effectively fire hose from freezing, and guarantees the operate as normal of fire fighting truck.
Description of drawings
Fig. 1 is the structural representation of the utility model fire fighting truck fire hose defroster.
The specific embodiment
See also the structural representation of the utility model fire fighting truck fire hose defroster shown in Figure 1, it comprise water pump 2, with water pump 2 and fire fighting truck water pot 1 between on the draw water pipeline 3 and the pipeline 3 that draws water that are connected control valve 20, fire hose 6 and fire hose 6 ends Fire branch 7, be installed in the air compressor 10 on the car body and be serially connected in compressed air control valve 11 on air compressor 10 export pipelines.
Be connected by power takeoff 9 between the output shaft of the rotating shaft of water pump 2 and fire fighting truck engine 8, water pump 2 outlets connect water pipe 5, control valve 16 is housed on it, connect fire monitor in control valve 16 back, outlet and the water pipe 5 between the control valve 16 at water pump 2 are connected with fire hose 6, compressed air control valve 11 is connected by the chamber of pipeline with water pump 2, and water pump 2 bottoms are equipped with by automobile-used accumulator jar electrically heated insulation draining valve 12 is provided.Water pump 2 chambers are connected with air compressor 10 and compressed air control valve 11, after fire fighting truck stops to spray, turn off the control valve 20 on the pipeline 3 that draws water earlier, open the draining valve 12 that connects on the water pump 2, to remain in the water pump 2 and the surplus water in the water pipe connecting 5 run out, again draining valve 12 cuts out, open compressed air control valve 11 and make air compressor 10 work, compressed air is introduced water pump 2, the surplus water that remains in the fire hose 6 is discharged from the nozzle 7 of Fire branch, on draining valve 12, heat in addition, draining valve 12 is freezed by storage battery, therefore prevented that effectively fire fighting truck water band from freezing, guaranteed the operate as normal of fire fighting truck.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
