Description

TECHNICAL FIELD

[0001] The utility model relates to fire fighting technical field especially relates to a kind of energy storage system fire suppression device. BACKGROUND

[0002] Traditional fire suppression methods, such as using manual fire extinguishers or simple water spray systems, often cannot meet the rapid response and efficient fire extinguishing needs of energy storage system fires. Manual fire extinguishers require personnel operation, and have the problems of long response time and limited fire extinguishing effect. The water spray system may cause electric shock risk due to electrical equipment in the energy storage system. In addition, these traditional methods often have difficulty in continuously providing sufficient fire extinguishing agent when facing large-scale fires, resulting in poor fire extinguishing effect.

[0003] To solve the above problems, some automated fire suppression systems have appeared in the market. However, these systems often have the problem of poor management of fire extinguishing agent pressure. During the fire extinguishing process, as the fire extinguishing agent is consumed, the pressure in the fire extinguishing agent tank gradually decreases, which will affect the spraying effect and fire extinguishing efficiency of the fire extinguishing agent. If the pressure is too low, the fire extinguishing agent may not be effectively sprayed to the fire area, thereby greatly reducing the fire extinguishing performance. Therefore, how to ensure that the pressure in the fire extinguishing agent tank always remains within the appropriate range becomes the key to improving the fire extinguishing effect of the fire suppression device. SUMMARY

[0028] The working principle of the energy storage system fire suppression device in this embodiment is as follows: when the fire monitoring device detects a fire in the fire protection area, the fire monitoring device controls the first electric control valve 22 to open through the fire extinguishing control line 3, so that the fire extinguishing agent in the fire extinguisher tank 2 flows quickly to the fire protection area along the fire extinguishing pipeline 21, and is sprayed out through the nozzles on the fire extinguishing pipeline 21 of the fire protection area to extinguish the fire (when the fire monitoring device detects that the fire has been extinguished, the fire monitoring device controls the first electric control valve 22 to close through the fire extinguishing control line 3 to stop the fire extinguishing action). During the entire process, the pressure monitor 4 monitors the pressure in the fire extinguishing agent tank in real time. When the pressure in the fire extinguisher tank 2 decreases to a standard threshold value (which is set according to the specific use) after part of the fire extinguishing agent in the fire extinguisher tank 2 is discharged, the pressure monitor 4 controls the second electric control valve 52 to open, so that the high-pressure gas in the pressure supplementing bottle 5 enters the fire extinguisher tank 2 through the pressure supplementing pipeline 51, so that the pressure in the fire extinguisher tank 2 recovers to the standard threshold value. When the pressure in the fire extinguisher tank 2 rises to the upper limit of the standard threshold value, the pressure monitor 4 controls the second electric control valve 52 to close, so that the pressure value in the fire extinguisher tank 2 can always be maintained within the standard threshold value, ensuring the efficient output of the fire extinguishing agent and preventing the fire extinguishing performance from being greatly reduced due to the decrease of the pressure in the fire extinguishing agent tank.

[0029] In one embodiment, the top of the fire extinguisher tank 2 is provided with a pressure gauge 23 for displaying the internal pressure in real time. By providing a pressure gauge 23 on the top of the fire extinguisher tank 2, which can display the internal pressure in real time, the operator can intuitively understand the pressure condition in the fire extinguisher tank 2 without relying on external equipment. This improves the readability and ease of use of the device, facilitating daily inspection and rapid judgment in emergency situations, and ensures that the pressure in the fire extinguishing agent tank is always within a controllable range.

[0030] In one embodiment, the fire extinguisher tank 2 and the pressure supplementing bottle 5 are fixed to the cabinet 1 by the bandage 6. By using the bandage 6 to fix the fire extinguisher tank 2 and the pressure supplementing bottle 5, the stability of the device is enhanced, and damage or leakage of the fire extinguisher tank 2 / pressure supplementing bottle 5 due to vibration during use is avoided, improving the overall safety.

[0031] In one embodiment, the bandage 6 and the cabinet 1 are connected by a threaded part. The bandage 6 and the cabinet 1 are connected by a threaded part (such as a screw, a nut), ensuring that the connection between the bandage 6 and the cabinet 1 is firm and reliable. Moreover, the bandage 6 connected by the threaded part is easy to disassemble, so that the fire extinguisher tank 2 or the pressure supplementing bottle 5 can be disassembled and replaced for maintenance.

[0032] In one embodiment, the fire monitoring device includes a temperature sensor and a smoke sensor. The fire monitoring device includes a temperature sensor and a smoke sensor, which can simultaneously monitor the temperature change and smoke concentration of the fire scene.
