Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: an energy storage power station fire protection system, including a plurality of fire extinguishing tanks 1, a plurality of battery prefabricated cabins 18 and a support frame 19. The fire extinguishing tanks 1 are installed on the upper end surface of the support frame 19. Adjacent fire extinguishing tanks 1 are connected through an M-shaped pipe 14. Fire pipes 9 are fixedly connected to the lower sides of the fire extinguishing tanks 1, and the front sides of the fire pipes 9 penetrate into the cabins of the battery prefabricated cabins 18. Hollow nozzles 13 are rotatably arranged at the front ends of the fire pipes 9. An installation box 11 is fixedly connected to the front side of the fire pipe 9. A detection unit is arranged in the installation box 11 for detecting the smoke and temperature values in the battery prefabricated cabin 18 in the energy storage power station. The detection unit is connected to a processor, and the processor is connected to a monitoring terminal. Liquid adding pipes 4 and pressure regulating pipes 7 are respectively fixedly connected to the upper ends of the left and right fire extinguishing tanks 1. Electromagnetic on-off valves 10 are fixedly communicated in the fire pipes 9.

[0024] First, connect the liquid adding device to the liquid adding pipe 4, and add fire extinguishing liquid to the left fire extinguishing tank 1. Since adjacent fire extinguishing tanks 1 are connected through the M-shaped pipe 14, it is convenient to add fire extinguishing liquid to multiple fire extinguishing tanks 1. After the fire extinguishing liquid in multiple fire extinguishing tanks 1 is added, connect the pressure regulating pipe 7 to an external pressurizing device to pressurize the fire extinguishing tanks 1. The detection unit monitors the smoke concentration and temperature value in the battery prefabricated cabin 18 in the energy storage power station, and processes the monitored data through the processor. When it is determined that a fire has occurred, the monitoring terminal opens the electromagnetic on-off valve 10 corresponding to the fire extinguishing tank 1, so that the fire extinguishing liquid enters the battery prefabricated cabin 18 where the fire has occurred through the fire pipe 9, which is convenient for timely detecting and extinguishing the fire in the battery prefabricated cabin 18; the model of this processor is the RS485 processor. The electromagnetic on-off valve 10 has been popularized in the market and belongs to a relatively mature existing technology, so no more detailed description will be given here.

[0025] The shape of the nozzle 13 is oval, and the first spray hole 16 and the second spray hole 17 are symmetrically arranged obliquely on the nozzle 13. When a fire occurs in the battery prefabricated cabin 18 in the energy storage power station, it is convenient for the fire extinguishing liquid in the fire extinguishing tank 1 to be transported to the position of the nozzle 13 through the fire pipe 9, so that the nozzle 13 rotates, which is convenient for spraying the fire position evenly over a large range and improving the efficiency of rapid fire extinguishing.

[0026] The detection unit includes a smoke sensor and a temperature sensor, which are used to detect the smoke concentration and temperature value in the battery prefabrication cabin 18, so as to more accurately prevent and extinguish the occurrence of fires.

[0027] The model of the smoke alarm is JTY-GM-HB603-485, and the model of the temperature sensor is DS18B20.

[0028] The fire-fighting material in the fire-fighting tank 1 is perfluoromethylcyclohexanone. Perfluoromethylcyclohexanone is in a liquid state and has a better fire-extinguishing effect. The bottom of the fire-fighting tank 1 is fixedly connected to a bottom plate 2. A plurality of through holes 3 are formed in the circumferential direction of the upper end surface of the chassis 2 for inserting locking screws into the through holes 3 so that the locking screws are threadedly connected to the support frame 19 to fix the position of the fire-fighting tank 1 on the upper end surface of the support frame 19.

[0029] A sleeve block 15 is fixedly connected to the lower part of the front end of the fire-fighting pipe 9. The outside of the sleeve block 15 is rotatably connected to a sleeve 12. The lower side of the sleeve 12 is fixedly connected to a nozzle 13. Through the rotational connection between the sleeve block 15 and the sleeve 12, when the nozzle 13 sprays the fire-fighting liquid, the nozzle 13 can freely rotate around the sleeve 12, improving the spraying area of the nozzle 13.

[0030] The upper ends of the liquid adding pipe 4 and the pressure regulating pipe 7 are both threadedly connected with a first sealing cap 5 and a second sealing cap 8. The fire-fighting liquid can be conveniently added through the liquid adding pipe 4. After the plurality of small fire-fighting tanks 1 are filled with the fire-fighting liquid, the pressure regulating pipe 7 is connected to an external pressurizing device to pressurize the plurality of fire-fighting tanks 1, facilitating the transportation of the fire-fighting liquid to the position of the nozzle 13 through the fire-fighting pipe 9.

[0031] A hollow observation rod 6 is fixedly communicated with the side wall of the rear fire-fighting tank 1. The observation rod 6 is made of a transparent material, facilitating the observation of the amount of fire-fighting liquid in the fire-fighting tank 1 so as to add the fire-fighting liquid to the fire-fighting tank 1 in time.

[0032] When the present utility model is in use, first connect the liquid adding device to the liquid adding pipe 4 and add the fire-fighting liquid into the leftmost fire-fighting tank 1. Since the adjacent fire-fighting tanks 1 are communicated through the M-shaped pipe 14, it is convenient to add the fire-fighting liquid into the plurality of fire-fighting tanks 1. After the fire-fighting liquid in the plurality of fire-fighting tanks 1 is added, connect the pressure regulating pipe 7 to an external pressurizing device to pressurize the fire-fighting tanks 1. The detection unit monitors the smoke concentration and temperature value in the battery prefabrication cabin 18 in the energy storage power station, and processes the monitored data through a processor. When it is determined that a fire has occurred, the monitoring terminal opens the electromagnetic solenoid valve 10 corresponding to the fire-fighting tank 1, so that the fire-fighting liquid enters the battery prefabrication cabin 18 where the fire has occurred through the fire-fighting pipe 9, facilitating the timely discovery and extinguishment of the fire in the battery prefabrication cabin 18.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
