Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion battery fire extinguishing devices, in particular to a lithium ion battery energy storage fire extinguishing device. Background Art

[0002] Lithium-ion battery fire extinguishing is an important and complex process, mainly because lithium-ion batteries may cause rapid fire spread due to thermal runaway in a fire. Therefore, special measures are required to extinguish lithium-ion battery fires.

[0003] In the prior art, once a fire occurs, people generally rely on traditional fire-fighting equipment for emergency disposal. However, when a lithium-ion battery catches fire, its unique deflagration phenomenon makes it difficult for conventional fire-fighting equipment to cope with it and cannot effectively curb the spread of the fire. In addition, lithium-ion batteries require ventilation for daily work to cool down, and an overly open environment will affect the efficiency of fire extinguishing. Therefore, it is particularly urgent and important to develop a professional fire-fighting device for lithium-ion battery fires. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art. The existing fire extinguishing equipment cannot effectively extinguish the explosion of lithium-ion batteries, which leads to the expansion of the fire and causes greater safety and property losses.

[0006] Optionally, the open end of the gas cylinder is connected to a delivery pipe, a one-way valve is provided at one end of the delivery pipe away from the gas cylinder, the one-way valve is connected to an injection pipe at one end of the delivery pipe away from the gas cylinder, and the injection pipe is inserted upward into the square groove.

[0007] Optionally, limiting rods are provided on both sides of the square groove close to the frame.

[0008] Optionally, a slide groove is provided on the frame near the limiting rod, and the limiting rod is slidably connected inside the slide groove.

[0009] Optionally, a bowl-shaped groove is fixed above the injection port of the injection pipe.

[0010] Optionally, a temperature sensor is provided on the square groove.

[0011] Optionally, the gas cylinder is filled with high-pressure fire-extinguishing liquid.

[0012] Optionally, the outer side of the protective box is clamped with stirrups.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] In the utility model, the bidirectional threaded screw is driven to rotate by the forward and reverse motor, and the movement of the bidirectional threaded screw drives the two moving blocks to move in relative or opposite directions along their axes. At the same time, the two limit rods are accurately lifted and lowered and slid in the vertical slide groove to ensure that the movement directions of the fixed bracket and the square groove are stable and controllable. In this way, the two moving blocks can only move away from or approach each other on the bidirectional threaded screw, and then the angle of the square groove is gradually adjusted from nearly vertical to downward tilted through the connecting rod, so that it can smoothly descend to the bottom of the protective box body, and the lid is closed to form a complete closed box body. This design effectively improves the efficiency of fire extinguishing. At the same time, the gas cylinder can spray fire extinguishing liquid into the interior of the square groove to quickly extinguish the fire. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a technical solution: a lithium-ion battery energy storage fire extinguishing device, including a protective box 1, a frame 7 and a forward and reverse motor 11 are arranged inside the protective box 1, a bidirectional threaded screw 12 is rotatably connected inside the frame 7, the output end of the forward and reverse motor 11 is connected to the bidirectional threaded screw 12, and the mirror threads on the left and right sides of the bidirectional threaded screw 12 are threadedly connected to a corresponding moving block 13, and the two moving blocks 13 are both rotated upward to connect a connecting rod 15, and the two connecting rods 15 are also rotatably connected to a corresponding mounting bracket 14 at one end away from the moving block 13, and the two mounting brackets 14 are fixed below the bracket 10, and a square groove 3 is fixed on the bracket 10, and a battery module 4 is installed inside the square groove 3, and a plurality of arc grooves 5 are arranged at the bottom of the square groove 3, and a gas cylinder 6 is fixed inside the arc groove 5, and limit rods 9 are arranged on both sides of the square groove 3 near the frame 7, and a slide groove 8 is opened at the frame 7 near the limit rod 9, and the limit rod 9 is slidably connected inside the slide groove 8.

[0025] In this embodiment, the bidirectional threaded screw 12 is driven to rotate by the forward and reverse motor 11, and the movement of the bidirectional threaded screw 12 drives the two moving blocks 13 to move in relative or opposite directions along their axes. At the same time, the two limit rods 9 are accurately lifted and slid up and down in the vertical slide groove 8 to ensure that the movement directions of the fixed bracket 10 and the square groove 3 are stable and controllable. In this way, the two moving blocks 13 can only move away from or approach each other on the bidirectional threaded screw 12, and then the angle of the square groove 3 is gradually adjusted from nearly vertical to downward tilted through the connecting rod 15, so that It can smoothly descend to the bottom of the protective box 1 and close the lid to form a complete enclosed box. This design effectively improves the efficiency of fire extinguishing. At the same time, the gas cylinder 6 can spray fire extinguishing liquid into the square groove 3 to quickly extinguish the fire. When the battery module 4 needs ventilation and heat dissipation, the forward and reverse motors 11 drive the moving blocks 13 to approach each other, so that the square groove 3 rises, thereby safely exposing the battery module 4 outside the protective box 1 to achieve the purpose of ventilation and heat dissipation. This design not only ensures the safety of the battery module 4, but also improves the flexibility and practicality of the entire system.

[0026] The open end of the gas cylinder 6 is connected to a delivery pipe 16 , and a one-way valve 17 is provided at one end of the delivery pipe 16 away from the gas cylinder 6 . The one-way valve 17 is connected to an injection pipe 18 at one end away from the delivery pipe 16 , and the injection pipe 18 is inserted upward into the square groove 3 .

[0027] In this embodiment, by opening the one-way valve 17, the high-pressure gas stored in the gas cylinder 6 will be sprayed into the interior of the square tank 3 through the delivery pipe 16 and the injection pipe 18, thereby extinguishing the fire.

[0028] A bowl-shaped groove 19 is fixed above the injection port of the injection pipe 18, a temperature sensor 20 is arranged on the square groove 3, the inside of the gas cylinder 6 is filled with high-pressure fire extinguishing liquid, and a stirrup 2 is clamped on the outside of the protective box body 1.

[0029] In this embodiment, the bowl-shaped groove 19 can prevent the liquid sprayed by the spray pipe 18 from spraying upward out of the square groove 3, thereby causing waste. The temperature sensor 20 can detect the abnormal temperature of the battery module 4 to perform fire extinguishing operations. The stirrups 2 can strengthen the strength of the protective box 1.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
