Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically a fire-fighting water supply device. Background Technology

[0002] Most existing electric bicycle sheds are rarely equipped with independent fire-fighting systems. They mostly just place fire extinguishers inside the shed and lack a proper water supply system. If a fire breaks out, it can easily spread and cause significant damage.

[0003] Therefore, there is an urgent need to develop a fire-fighting water supply device to solve the problems in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a fire-fighting water supply device that can be used for fire-fighting water supply, and has a simple structure and is easy to use, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] It also includes a control box, and the second diversion pipe has several outlets with partition valves at the end away from the water pump. The water pump and the partition valves are both connected to the control box via electrical signals.

[0008] By adopting the above technical solution, when the control box receives a water supply signal, it controls the water pump to work. The water pump sends the water in the water tank to the second branch pipe through the first branch pipe. Then, the control box controls the corresponding zone valve to open and sends the water to the corresponding zone for fire protection.

[0009] As a further aspect of this utility model, a pressure relief pipe for connection is provided between the first diversion pipe and the second diversion pipe.

[0010] By adopting the above technical solution, the pressure relief pipeline is used to balance the pressure difference caused by several water pumps not starting at the same time.

[0011] As a further embodiment of this utility model, a safety valve is provided on the pressure relief pipeline.

[0012] By adopting the above technical solution, the safety valve can be manually opened and closed to balance the pressure difference.

[0013] As a further embodiment of this utility model, a pressure gauge for monitoring is provided on the second diversion pipe.

[0014] By adopting the above technical solution, the pressure gauge mainly plays a monitoring role, used to understand the water pressure in the pipeline, and serves as the main basis for determining whether the relief valve needs to be opened.

[0015] As a further embodiment of this utility model: the second diversion pipe is provided with an outlet equipped with a drain valve.

[0016] By adopting the above technical solution, the relief valve is mainly used to balance the pressure of the second diversion pipe.

[0017] As a further embodiment of this utility model, a check valve is provided at the connection between the water pump and the second diversion pipe.

[0018] By adopting the above technical solution, the check valve is installed to prevent water backflow caused by high water pressure in the pipeline.

[0019] As a further embodiment of this utility model: a filter is provided between the first diversion pipe and the water tank.

[0020] By adopting the above technical solution, the filter is installed to reduce the entry of impurities such as mud and sand into the pipeline, thereby reducing the service life of the pipeline and water pump.

[0021] As a further embodiment of this utility model: a magnetic float level transmitter is provided at the top of the water tank.

[0022] By adopting the above technical solution, the magnetic float level transmitter is mainly used to determine the liquid level in the water tank.

[0023] Compared with the prior art, the advantages of this utility model are: it can be used for fire water supply, and its structure is simple and easy to use.

[0029] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In this embodiment of the utility model, a fire-fighting water supply device is described, see [link / reference] Figure 1-3 As shown, it includes a water supply device 2 for use in an electric bicycle shed 1; the water supply device 2 includes several water tanks 21 and several water pumps 22 connected to the water tanks 21 through a first diversion pipe 201, and the water pumps 22 are connected to the shed 1 through a second diversion pipe 202;
