A fire suppression apparatus for an energy storage plant

Abstract

This utility model relates to the field of fire protection technology, specifically to a fire suppression device for energy storage power stations, comprising: a suppression frame; mounting frames fixed at both ends of the suppression frame; and multiple suppression frames installed vertically and horizontally via the mounting frames. In this utility model, the device forms a local fire suppression system through a fire extinguishing pipe extending from the rear of the placement frame, a connecting pipe with a solenoid valve, and an external fire extinguishing gas cylinder, with the fire extinguishing pipe directly corresponding to the battery placement area. When a fire detector triggers a signal, the solenoid valve can quickly open, allowing the fire extinguishing medium to be precisely delivered through the fire extinguishing pipe to the burning battery cell or local battery pack, eliminating the need for diffusion in a large space. This improves the utilization rate and efficiency of the fire extinguishing medium, and avoids the immersion damage (water-based) or low-temperature impact (gas) to unburned, normal batteries caused by traditional integrated fire suppression systems, minimizing secondary equipment damage and reducing the probability of reignition.

Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically to a fire suppression device for energy storage power stations. Background Technology

[0002] In the process of transitioning the energy structure towards cleaner and lower-carbon energy, energy storage power stations, as key infrastructure for achieving efficient absorption of renewable energy (such as wind and solar power) and ensuring the stable operation of the power system, are experiencing rapid expansion in application scale. The core component of an energy storage power station is the energy storage battery. However, current mainstream types of energy storage batteries, such as lithium-ion batteries, are prone to thermal runaway under conditions such as long-term charge-discharge cycles, local circuit failures, abnormal ambient temperatures (such as high temperatures), or mechanical collisions. This occurs when the electrolyte inside the battery decomposes to produce flammable gases (such as methane and carbon monoxide), accompanied by a rapid increase in temperature, which can lead to smoke, fire, or even explosion, posing a serious threat to the safety of power station equipment, personnel, and the surrounding environment.

[0003] However, traditional solutions rely on fire detection of the entire power plant area (such as smoke detectors and temperature sensors), while energy storage battery packs are mostly densely stacked. The local high temperature, trace amount of smoke or combustible gas in the early stage of thermal runaway of a single battery are easily diluted by the overall environment, resulting in delayed detection signals and failure to intervene in time at the incipient stage of fire, thus missing the best opportunity to suppress the fire.

[0004] Therefore, those skilled in the art have provided a fire suppression device for energy storage power stations to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides:

[0006] A fire suppression device for an energy storage power station includes: a suppression frame; and mounting frames are fixed at both the upper and lower ends of the suppression frame.

[0007] Furthermore, the multiple suppression frames are installed vertically and horizontally via an assembly frame;

[0008] An energy storage battery placement unit is installed inside the suppression frame;

[0009] The energy storage battery placement unit includes a placement frame that is movably disposed inside the suppression frame, and two sets of tension springs are installed between the placement frame and the suppression frame;

[0010] A reset frame is fixed on the suppression frame, and a rotating wheel one and a rotating wheel two are rotatably mounted on the inner side of the reset frame. A steel wire rope is wound around the inner side of the rotating wheel one and the rotating wheel two, and one end of the steel wire rope is connected to a closed cover installed on the suppression frame. A reset shaft is rotatably mounted on the closed cover, and the closed cover is rotatably mounted on the suppression frame via the reset shaft.

[0011] The other end of the steel wire rope is fixedly connected to the placement frame.

[0012] Preferably, a fire detector is installed on the sealed cover.

[0013] The fire detector has a built-in temperature sensor, smoke sensor and combustible gas detector.

[0014] Preferably, the inner walls of the suppression frame and its placement frame are provided with slots, the slots contain built-in blocks, and an electric push rod is assembled between the blocks and the suppression frame.

[0015] Preferably, the placement rack holds an energy storage battery for an energy storage power station.

[0016] Preferably, the inner side of the placement rack is provided with two sets of adjustment grooves, and a bidirectional lead screw is rotatably mounted on the inner side of the adjustment groove. The bidirectional lead screw is fixedly connected to a worm gear, and the worm gear meshes with a worm.

[0017] The outer helical drive sleeve of the bidirectional lead screw is equipped with a clamping plate that is movably located inside the adjustment groove.

[0018] The two sets of bidirectional lead screws are identical, and the worm gear meshes synchronously with the worm wheel, so the two sets of bidirectional lead screws rotate synchronously.

[0019] Preferably, both ends of the bidirectional lead screw are fixedly connected to hexagonal internal rods.

[0020] Preferably, a fire extinguishing pipe is connected to the rear side of the placement rack, one end of the fire extinguishing pipe is connected to a connecting pipe, and a solenoid valve is installed between the connecting pipe and the fire extinguishing pipe.

[0021] The connecting pipe is connected to an external fire extinguishing gas cylinder.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] This invention relates to a device that forms a localized fire suppression system through a fire extinguishing pipe extending from the rear of the mounting frame, a connecting pipe with a solenoid valve, and an external fire extinguishing gas cylinder. The fire extinguishing pipe directly corresponds to the battery placement area. When a fire detector triggers a signal, the solenoid valve opens rapidly, allowing the fire extinguishing medium to be precisely delivered through the fire extinguishing pipe to the burning individual battery cell or local battery pack. This eliminates the need for diffusion within a large space, improving the utilization rate and efficiency of the fire extinguishing medium. Furthermore, it avoids the damage caused by immersion (water-based) or low-temperature impact (gas) to unburned, normal batteries, as is common with traditional integrated fire suppression systems. This minimizes secondary damage to the equipment and reduces the probability of reignition. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The examples of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0036] Example: Please refer to Figures 1 to 7This embodiment provides a fire suppression device for an energy storage power station, including: a suppression frame 1; an assembly frame 2 is fixed at both the upper and lower ends of the suppression frame 1; and multiple suppression frames 1 are installed vertically and horizontally through the assembly frame 2; an energy storage battery placement unit 3 is installed inside the suppression frame 1;

[0037] The energy storage battery placement unit 3 includes a placement frame 301 movably disposed inside the suppression frame 1, and two sets of tension springs 14 are installed between the placement frame 301 and the suppression frame 1; a reset frame 7 is fixed on the suppression frame 1, and a rotating wheel 8 and a rotating wheel 9 are rotatably mounted inside the reset frame 7, and a steel wire rope 10 is wound around the inner side of the rotating wheel 8 and the rotating wheel 9, and one end of the steel wire rope 10 is connected to a closed cover 12 installed on the suppression frame 1, and a reset shaft 11 is rotatably mounted on the closed cover 12, and the closed cover 12 is rotatably mounted on the suppression frame 1 via the reset shaft 11;

[0038] The other end of the steel wire rope 10 is fixedly connected to the placement frame 301; a fire detector 13 is installed on the closed cover 12; the fire detector 13 has a built-in temperature sensor, smoke sensor and combustible gas detector; the inner wall of the suppression frame 1 and the placement frame 301 are provided with slots 15, the slots 15 have built-in blocks 16, and an electric push rod 17 is assembled between the blocks 16 and the suppression frame 1;

[0039] The placement rack 301 holds an energy storage battery body 18 for an energy storage power station. Two sets of adjustment slots 302 are provided inside the placement rack 301. A bidirectional lead screw 303 is rotatably mounted inside each adjustment slot 302. The bidirectional lead screw 303 is fixedly connected to a worm gear 304, and the worm gear 304 meshes with a worm 305. A clamping plate 307 is movably mounted on the outer side of the bidirectional lead screw 303, located inside the adjustment slot 302. The two sets of bidirectional lead screws 303 are identical, and the worm 305 meshes synchronously with the worm gear 304, causing the two sets of bidirectional lead screws 303 to rotate synchronously. Both ends of the bidirectional lead screw 303 are fixedly connected to hexagonal rods 306. A fire extinguishing pipe 4 is connected through the rear of the placement rack 301. One end of the fire extinguishing pipe 4 is connected to a connecting pipe 5, and a solenoid valve 6 is installed between the connecting pipe 5 and the fire extinguishing pipe 4. The connecting pipe 5 connects to an external fire extinguishing gas cylinder.

[0040] The working principle of the above embodiments is as follows:

[0041] The fire detector 13 (with built-in temperature, smoke, and combustible gas sensors) installed on the sealed cover 12 monitors the environmental status in real time.

[0042] Once an anomaly is detected (such as increased temperature, excessive smoke or combustible gas concentration), the system determines that a fire has occurred.

[0043] The fire signal triggers the opening of the solenoid valve 6, allowing the extinguishing agent in the external fire extinguishing gas cylinder to enter the placement rack 301 through the connecting pipe 5 and the fire extinguishing pipe 4, and extinguish the fire on the energy storage battery body 18.

[0044] While extinguishing the fire, the system activates the electric push rod 17, which pushes the locking block 16 out of the locking slot 15, releasing the fixation of the placement rack 301;

[0045] Under the action of tension spring 14, the placement frame 301 pops outward, loosening the steel wire rope 10;

[0046] The steel wire rope 10 passes around the rotating wheel 8 and the rotating wheel 9, driving the closed cover 12 to rotate around the reset shaft 11, quickly closing the opening of the suppression frame 1, forming a sealed space to prevent the fire from spreading and oxygen from entering;

[0047] The reset shaft 11 has a built-in spiral spring. When the wire rope 10 loosens, the spiral spring resets the sealing cover 12 on the reset shaft 11 and closes the suppression frame 1.

[0048] Normally, the worm gear 305 can be rotated to drive the worm wheel 304, which in turn drives the bidirectional lead screw 303 to rotate, so that the clamping plates 307 on both sides can move inward or outward simultaneously to accommodate energy storage battery bodies 18 of different sizes.

[0049] The 306 hex socket provides a manual adjustment interface for easy installation and maintenance.
