Background

Fire is an important factor for promoting the progress of human civilization, but fire often accompanies the human civilization, and property loss and casualties are caused. How to avoid a fire and save oneself in a fire is a matter that the public has to think and participate. The education of fire prevention and extinguishment has also been popularized for many years, but because the fire-fighting facilities are expensive, the personnel organization training also stays in listening and watching, and the practical operation has many effects which cannot be achieved.

As is well known, in the case of residential and public building fires, water is the main force for fire extinguishing, so that it is very important to keep the equipment of the building fire-fighting water system intact, and meanwhile, the equipment for operating the fire-fighting water system is also the necessary skill of fire-fighting managers. Property personnel (including control room operators) are not familiar with the operation of the waterproofing system and need specialized training before they can learn to operate. The fire-fighting training institutions of all provinces and cities are provided with training points in urban areas and lack the training points of surrounding villages, towns and counties. Therefore, students in villages, towns and counties need to go back and forth in two places during training, and time and labor are wasted. Through the equipment, people can be summoned to train on the enterprise site no matter in a training institution or each social enterprise.

Therefore, it is very important to design and manufacture a mobile training device.

Principle of operation

The invention relates to a mobile training device, which comprises two systems, namely a fire hydrant system and a spraying system. The main equipment in the fire hydrant system comprises an indoor fire hydrant box and a fire hydrant pump. The main equipment in the spraying system comprises a spraying pump, a wet type alarm valve group, a pre-acting alarm valve group, an air compressor and two spray head pipelines.

The main equipment of the pipeline of the spraying system comprises a pipeline control valve, a spraying pump, a wet type alarm valve group, a pre-acting alarm valve group, an air pressure maintenance device, an air compressor, a closed type spray head, a tail end water testing device and the like, wherein the pre-acting alarm valve group is also provided with a special exhaust valve and an electromagnetic valve. The pipelines of the two valve groups are independent respectively, and respective system side valves are used as dividing points. The spraying system is divided into two small systems, namely a wet system and a pre-acting system according to different used alarm valve sets.

Wet system: in the quasi-working state, the pressure of water filled in the pipeline is maintained by pressure-stabilizing facilities such as a fire water tank or a pressure-stabilizing pump, air pressure water supply equipment and the like. When a fire disaster happens, under the action of the fire disaster temperature, the thermosensitive element of the closed spray head acts, and the spray head is opened and starts to spray water. At the moment, the water in the pipe network changes from static state to flowing state, the water flow indicator acts to send out an electric signal, and the information of water spraying in a certain area is displayed on the alarm controller. Because the upper water pressure of the wet alarm valve is lower than the lower water pressure due to continuous water spraying and pressure relief, the wet alarm valve which is originally in a closed state is automatically opened under the action of pressure difference. At the moment, the pressure water flows to the pipe network through the wet alarm valve, a channel leading to the hydraulic alarm bell is opened, after the delayer is filled with water, the hydraulic alarm bell gives out an alarm, and the pressure switch acts and outputs a signal for starting the water supply pump. And after the water supply pump is put into operation, the starting process of the system is completed.

The preaction system comprises: the pre-acting alarm valve group can be regarded as a combination of a wet alarm valve and a deluge alarm valve. In the servo state, the wet alarm valve and the system side pipeline are not filled with water, and only a few low-pressure air exists. If the spray head is broken by mistake, the air in the pipeline is discharged, at the moment, the valve group can not act, the water on the water supply side can not enter the system side, and therefore the spray head can not spray water. If the valve group malfunctions (the manual emergency starting device is opened by mistake or the electromagnetic valve is opened), water on the water supply side can enter the system side after the valve clack is opened, but no water can be sprayed out because no spray head is broken. When a fire occurs in a protection area, the fire alarm detector gives an alarm and transmits information to the fire alarm linkage controller, after the linkage relation requirement is met, the linkage controller starts the electromagnetic valve of the pre-acting valve group, water can be filled in a pipeline on the side of the system, the system is converted into a wet system, and the process is a pre-acting process of the system. Meanwhile, the hydraulic alarm bell gives an alarm, and the pressure switch outputs an alarm signal. If the fire condition continues to develop, the spray head can break, and at the moment, the spray head can spray water to extinguish fire.

Water in the fire pool 8 enters the fire pumps 95 and 103 through the fire hydrant pipeline 9 and the spraying pipeline 10, the tail end of the fire hydrant pipeline 9 is a reserved opening and can be connected with indoor and outdoor fire hydrants or a water pump adapter, and the pump starting operation can be completed through a fire hydrant button in a fire hydrant box in the room;

the spray pipeline 10 is connected with a wet alarm valve group 109, when no spray head on the signal valve branch pipeline 111 is broken, the water pressure of the system side and the water supply side of the wet alarm valve group 109 is kept balanced, and the system is in a quasi-working state; when the spray head 113 or 114 is broken, water on the system side flows out through the broken spray head, so that the system side pressure is reduced, the pressure on the water supply side is higher than that on the system side, a valve clack of the wet alarm valve set 109 is opened, water flows to the system side from the water supply side, meanwhile, part of water reaches a pressure switch and a hydraulic alarm bell through a delayer of the wet alarm valve set, after the pressure switch acts, an action signal can be transmitted to a fire alarm host, a spray pump can be started in a linkage manner, and after the hydraulic alarm bell acts, an alarm sound is given out; when water flows through the water flow indicator 112, the water flow indicator 112 converts the water flow signal into an electric signal and feeds the electric signal back to the fire alarm main machine; at the moment, the fire alarm host can receive feedback signals of the pressure switch and the water flow indicator, the field spray pump is started, and the spray head sprays water, so that the purposes of alarming and extinguishing fire are achieved, and in addition, the arranged water pump control cabinet 11 can perform the operation of manually starting and stopping the fire pump on site and the operation of remotely starting and stopping the fire pump (through the fire alarm host); after the switch 107, a pipeline interface can be reserved, and a dry type alarm valve group and a rain alarm valve group are additionally arranged; the fire water tank 121 of the second frame 12 is connected with pressure stabilizing pumps 127 and 138 and is connected with a pressure stabilizing tank; the 123 three-way pipe is connected with the 116 three-way pipe of the frame 1 to form a self-priming pipeline, and the 134 three-way pipe is connected with a pipeline behind the system side signal valve 110 of the frame 1 and in front of the branch pipeline 111 and a pressure stabilizing tank to form a pressure stabilizing pipeline; when water in the pressure stabilizing pipeline is lost (the pipeline leaks water or the indoor fire hydrant discharges water and the spray head discharges water), the pressure of the pipeline is reduced, and when the pressure is reduced to the lower limit of the electric contact pressure gauges 132 and 143, the fire hydrant or the spraying pressure stabilizing pump can be started to supplement pressure to the pipeline. When the pressure is replenished to the upper limit of the electro-contact pressure gauges 132, 143, the pressure maintenance pump is stopped. The system voltage stabilization is completed by the circulation; in addition, the pressure stabilizing pump control cabinet 150 can be used for manually starting and stopping the fire-fighting pressure stabilizing pump on site, and can also be used for manually adjusting the upper and lower limit values of the electric

contact pressure gauges

132 and 143 on site to manually test the starting and stopping functions of the pressure stabilizing pump; the invention can meet all teaching drills about fire fighting water systems in New teaching materials and New standards of 'fire fighting Equipment operators' 2020.
