Description

Technical Field

[0001] This utility model relates to the field of fire protection facilities technology, specifically a drainage control system based on the use of fire hose reels. Background Technology

[0002] Traditional fire hose reel systems rely on underground drainage wells for water discharge. However, drainage wells are expensive and require regular maintenance, which is difficult and increases construction costs. In addition, traditional drainage requires manual opening of the well cover and valves, resulting in low emergency response efficiency and the inability to promptly fill the fire hose reel with water for fire extinguishing. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a drainage control system based on fire hose reel, which can replace the traditional drainage well, reduce construction costs, improve emergency response efficiency, and extinguish fires in a timely manner, thus effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drainage control system based on fire hose reels, comprising a connecting pipe, the lower end of which is below ground level and connected to a water supply main pipe, an electric self-draining valve seat inside the connecting pipe, the electric self-draining valve seat including a drainage control valve and a drainage outlet, the drainage outlet being located on the outer side of the lower end of the connecting pipe, the upper end of the connecting pipe extending above ground level, and one end of the connecting pipe being connected to the drainage control valve, the other end of the connecting pipe being connected to a connecting pipe via a pipeline, the connecting pipe being connected to the fire hose in the reel box, a water supply control valve being provided on the connecting pipe, a branch pipe being provided on the outer side of the connecting pipe, the branch pipe being located above the water supply control valve, and an vent valve being provided on the branch pipe.

[0005] As a preferred embodiment of this utility model, the reel box is provided with a control switch, and the output terminal of the control switch is electrically connected to the input terminals of the drain control valve and the water supply control valve, respectively.

[0006] As a preferred technical solution of this utility model, a relay is provided on the connection line between the control switch and the drain control valve and the water supply control valve, which is used to control the delayed opening between the drain control valve and the water supply control valve.

[0007] As a preferred embodiment of this utility model, the vent valve is a manual valve.

[0008] In a preferred embodiment of this utility model, the drain outlet is located underground, while the drain control valve, water supply control valve, and vent valve are located above ground.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This water drainage control system based on fire hose reels uses an electric self-draining valve seat installed on the underground connecting pipe. After the fire is extinguished, the accumulated water below the water supply control valve is discharged to the underground pebble layer through the drain outlet. By setting an vent valve, the accumulated water in the pipeline above the water supply control valve can be drained, eliminating the need to build a drain well and reducing construction costs. At the same time, a control switch is installed in the reel box to control the activation of the water drainage control valve and the water supply control valve, improving emergency response efficiency and enabling rapid fire extinguishing.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Please see Figure 1 This utility model provides a technical solution: a drainage control system based on fire hose reel, including a connecting pipe 1, the lower end of the connecting pipe 1 is located below ground and connected to the water supply main pipe, an electric self-draining valve seat is provided in the connecting pipe 1, the electric self-draining valve seat includes a drainage control valve 2 and a drainage port 3, the drainage port 3 is located on the outer side of the lower end of the connecting pipe 1 and is located in the underground pebble layer, the drainage control valve 2 controls the opening or closing of the drainage port 3 through related components, which is the prior art;

[0014] The upper end of the connecting pipe 1 extends out of the ground, and one end of the connecting pipe 1 is connected to the drain control valve 2. The pipe behind the drain control valve 2 is empty. The other end of the connecting pipe 1 is connected to the connecting pipe 7 through a pipe. The connecting pipe 7 is connected to the fire hose in the hose reel box. A water supply control valve 4 is installed on the connecting pipe 7. A branch pipe 8 is installed on the outer side of the connecting pipe 7. The branch pipe 8 is located above the water supply control valve 4. A vent valve 5 is installed on the branch pipe 8. The drain control valve 2, the water supply control valve 4, and the vent valve 5 are located above the ground.

[0015] To ensure rapid activation of the fire hose in emergency situations, a control switch 6 is installed in the hose reel box. The output of the control switch 6 is electrically connected to the inputs of the drain control valve 2 and the supply control valve 4, respectively. A relay is installed on the connection line between the control switch 6 and the drain control valve 2 and the supply control valve 4 to control the delayed opening between the drain control valve 2 and the supply control valve 4. The delay time can be automatically adjusted according to the depth of the underground water supply main. By setting the delay, in emergency situations, the drain control valve 2 can be opened first, followed by the automatic opening of the supply control valve 4, allowing the pipeline to quickly fill with water for rapid fire extinguishing. During drainage, the supply control valve 4 is closed first, followed by the drain control valve 2, allowing the water accumulated in the supply control valve 4, the drain control valve 2, and the pipeline below to be drained through the drain port 3.

[0016] In order to drain the water accumulated in the pipeline above the water supply control valve 4, the vent valve 5 is a manual valve for easy manual operation.

[0017] During use: In normal standby mode: drain control valve 2 is closed, water supply control valve 4 is closed, vent valve 5 is closed, and the pipe after drain control valve 2 is empty.

[0018] Emergency use status: When the fire hose reel is needed, press the control switch 6 inside the box. The drain control valve 2 will open automatically first. After a 30-second delay, the water supply control valve 4 will open automatically. The drain outlet 3 will be closed, and the pipeline will be quickly filled with water to extinguish the fire.

[0019] Water discharge stage: After use, retract the fire hose reel and press the control switch 6 inside the box. At this time, the water supply control valve 4 will close first. After a delay of 30 seconds, the water discharge control valve 2 will close and the drain port 3 will open. The water accumulated in the body of the water supply control valve 4 and the water discharge control valve 2 will be discharged through the drain port 3. Manually open the vent valve 5 to drain the water accumulated in the upper pipeline of the water supply control valve 4. After completion, close the vent valve 5.
