Description

Technical Field

[0001] This utility model relates to the field of battery safety technology, and in particular to a lithium battery fire extinguishing agent box with a rapid release structure. Background Technology

[0002] Lithium battery fires are a serious safety issue. Lithium batteries contain flammable electrolytes, mainly composed of carbonate organic solvents such as ethylene carbonate and dimethyl carbonate, which are highly flammable.

[0003] A search revealed Chinese Patent Publication No. CN219323806U, which discloses a fireproof and fire-extinguishing lithium battery storage device. The burning lithium battery causes a fuse to melt, and under the compression of a spring, a fireproof cloth is stretched and pulled out from the bottom of the storage compartment, enclosing the burning lithium battery and isolating it from the surrounding environment. Simultaneously, the glass column in the fire sprinkler head breaks due to the high temperature, spraying a water-based fire extinguishing agent into the burning storage compartment. This fills the compartment containing the burning lithium battery with the water-based fire extinguishing agent, completely submerging the lithium battery and achieving the best fire extinguishing effect. This avoids the risk of reignition associated with fire extinguishing agents such as heptafluoropropane and perfluorohexanone, and also prevents greater losses.

[0004] In certain lithium battery applications, such as small, portable lithium battery devices, overly complex fire detection and control functions are not required, and cost and space constraints must be considered, making precise fire extinguishing within a small area impossible. Therefore, a lithium battery fire extinguishing agent cartridge with a rapid release structure is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lithium battery fire extinguishing agent box with a rapid release structure, which aims to improve the problems of high fire extinguishing cost and limited fire extinguishing space in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a lithium battery fire extinguishing agent box with a rapid release structure, comprising a main body of the agent box, the interior of which is filled with fire extinguishing agent, a first side plate and a second side plate fixedly connected to the bottom of the main body of the agent box, a placement box fixedly connected to the bottom of the first side plate and the second side plate, the top of the placement box being open, a lithium battery being placed inside the placement box, the bottom of the main body of the agent box being open, and a first opening / closing plate hinged to the bottom of the agent box. The second hinged plate has grooves on one side adjacent to both the first and second hinged plates. A spring is fixedly connected to the groove wall of the first hinged plate, and a limit block is fixedly connected to the other end of the spring. The outer wall of the limit block contacts the groove walls of the first and second hinged plates respectively. A safety rope is provided between the first and second side plates. One end of the safety rope movably passes through the groove wall of the second hinged plate and extends outward. The extended end of the safety rope movably passes through the second side plate and the first side plate in sequence. Replacement components are provided at both ends of the safety rope.

[0007] As a further description of the above technical solution: the replacement component includes a connecting ring, which is fixedly connected to one side of the limiting block, and the other end of the safety rope is tied to the inner side of the connecting ring, with the end of the safety rope passing through the first side plate and knotted.

[0008] As a further description of the above technical solution: a fixed pulley is fixedly connected to one side of the second side plate, and the surface of the safety rope is in contact with the surface of the fixed pulley.

[0009] As a further description of the above technical solution: the top of the second opening and closing plate is provided with an inspection hole, and a sliding cover is slidably connected to the top of the second opening and closing plate. The sliding cover is configured to cooperate with the inspection hole, and the groove opened in the second opening and closing plate is connected to the inspection hole.

[0010] As a further description of the above technical solution: the top of the medicine box body is provided with a feed port, and the inner wall of the feed port is in contact with a sealing cap.

[0011] As a further description of the above technical solution: the limiting block is strip-shaped, and the number of springs is three, which are symmetrically arranged at equal intervals.

[0012] As a further description of the above technical solution: a fireproof inclined plate is fixedly connected to the top of the placement box, and the fireproof inclined plate is configured in conjunction with a safety rope.

[0013] As a further description of the above technical solution: the top of the medicine box body and the bottom of the placement box are respectively fixedly connected to the mounting plate, and the mounting plate has a mounting hole on one side.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the fire extinguishing agent box body is triggered by arranging a safety rope. When a lithium battery catches fire, the fire extinguishing agent box body is quickly activated by burning the safety rope, which quickly floods the extinguishing agent to the ignition point. In complex fire scene environments, the fire extinguishing device triggered by breaking the safety rope can accurately extinguish fires in a small area by using an appropriate extinguishing agent, reducing the impact on other surrounding equipment.

[0016] 2. In this utility model, the replacement component allows for easy release of the limit on the burned safety rope by opening the inspection hole with a sliding cover, and also facilitates the replacement of the safety rope. The fireproof inclined plate ensures that when the lithium battery located below the fireproof inclined plate is burning, it can burn through the middle part of the safety rope, preventing the fire from spreading outward and damaging the fixed pulley. Therefore, it can be reused. Attached Figure Description

[0024] 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.

[0025] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides an embodiment of a lithium battery fire extinguishing agent box with a rapid release structure, comprising a main body 1, the main body 1 being filled with fire extinguishing agent for extinguishing burning lithium batteries 8, an inlet at the top of the main body 1 for adding fire extinguishing agent when the amount of fire extinguishing agent inside the main body 1 is insufficient, the inlet being used to add more fire extinguishing agent, the inner wall of the inlet being in contact with a sealing cap 7 to improve the sealing of the main body 1, a first side plate 3 and a second side plate 4 being fixedly connected to the bottom of the main body 1 to provide support, and a placement box being fixedly connected to the bottom of the first side plate 3 and the second side plate 4. 2. The interior of the placement box 2 is used to install lithium batteries 8. Mounting plates 5 are fixedly connected to the top of the main body 1 and the bottom of the placement box 2. Mounting plates 5 have mounting holes on one side for easy installation of the device with external components. The top of the placement box 2 is open, and lithium batteries 8 are placed inside. The number of lithium batteries 8 can be set according to the size of the placement box 2. The bottom of the main body 1 is open, and a first opening plate 12 and a second opening plate 14 are hinged to the bottom of the main body 1. When the first opening plate 12 and the second opening plate 14 are opened in opposite directions, the extinguishing agent inside the main body 1 is rapidly released under inertia, achieving rapid fire extinguishing and improving fire extinguishing efficiency.

[0026] Reference Figure 3 , Figure 4 , Figure 5Both the first opening plate 12 and the second opening plate 14 have grooves on their adjacent sides. The top of the second opening plate 14 has an inspection hole, and a sliding cover 15 is slidably connected to the top of the second opening plate 14. The sliding cover 15 is configured to cooperate with the inspection hole. The groove in the second opening plate 14 is connected to the inspection hole. When the safety rope 11 needs to be replaced, simply slide the sliding cover 15 to open the inspection hole. The burnt safety rope 11 can be taken out through the inspection hole and the new safety rope 11 can be installed. The safety rope 11 is reattached to the groove of the second opening plate 14. A spring 17 is fixedly connected to the groove wall of the first opening plate 12. The spring 17 is always taut. The other end of the spring 17 is fixedly connected to a limit block 16, allowing the limit block 16 to enter the groove of either the first opening plate 12 or the second opening plate 14. The outer wall of the limit block 16 contacts the groove walls of the first opening plate 12 and the second opening plate 14, respectively. The first opening plate 12 and the second opening plate 14... The first and second opening plates 12 and 14 are supported and limited by the limiting block 16 in the groove, so that the first opening plate 12 and the second opening plate 14 are locked in a horizontal position. The limiting block 16 is strip-shaped, and there are three springs 17, which are symmetrically arranged at equal intervals. Since there is a gap on the side of the first opening plate 12 and the second opening plate 14, the strip-shaped limiting block 16 can cover the gap in the middle. A safety rope 11 is provided between the first side plate 3 and the second side plate 4. One end of the safety rope 11 moves through the groove wall of the second opening plate 14 and extends outward. The extended end of the safety rope 11 moves through the second side plate 4 and the first side plate 3 in sequence, so that the safety rope 11 is horizontally placed above the lithium battery 8. A fixed pulley 6 is fixedly connected to one side of the second side plate 4. The surface of the safety rope 11 is in contact with the surface of the fixed pulley 6. The fixed pulley 6 can change the direction of the tension of the safety rope 11. Replacement components are provided at both ends of the safety rope 11.

[0027] Reference Figure 3 , Figure 4 , Figure 5 The replacement component includes a connecting ring 10, which is fixedly connected to one side of the limiting block 16. The connecting ring 10 is used to attach the safety rope 11. The other end of the safety rope 11 is attached to the inner side of the connecting ring 10. The connecting ring 10 limits one end of the safety rope 11. The safety rope 11 passes through one end of the first side plate 3 and is knotted. The knot limits the other end of the safety rope 11. After the safety rope 11 is arranged, it can be suspended horizontally above the lithium battery 8. The top of the placement box 2 is fixedly connected to a fireproof inclined plate 9. The fireproof inclined plate 9 is set in conjunction with the safety rope 11. The fireproof inclined plate 9 allows the middle part of the safety rope 11 to be burned off when the lithium battery 8 located below the fireproof inclined plate 9 is burning, preventing the fire from spreading outward and damaging the fixed pulley 6.

[0028] Working principle: When the lithium battery 8 inside the box 2 catches fire, the fireproof inclined plate 9 causes the lithium battery 8 located below the fireproof inclined plate 9 to burn through the middle part of the safety rope 11. The burned safety rope 11 begins to contract under the lateral elastic potential energy of the spring 17. At the same time as the safety rope 11 burns through, the spring 17 also drives the limiting block 16 to rebound until the limiting block 16, the connecting ring 10 and the groove of the second opening and closing plate 14 are separated. This allows the first opening and closing plate 12 and the second opening and closing plate 14 to rotate in opposite directions, causing the fire extinguishing agent inside the agent box body 1 to be released rapidly under inertia, thereby extinguishing the fire on the lithium battery 8 below. Firefighting can be carried out; after the fire is extinguished, the sealing cover 7 can be opened to add fire extinguishing agent into the body of the agent box 1; when the safety rope 11 needs to be replaced, simply slide the sliding cover 15 to open the inspection hole, take out the burnt safety rope 11 through the inspection hole, tie one end of the new safety rope 11 to the connecting ring 10, and pass the other end of the new safety rope 11 through the inner wall of the second opening plate 14 and around the surface of the setting pulley 6. This can change the direction of the tension of the safety rope 11. Then pass the safety rope 11 through the second side plate 4 and the first side plate 3, and tie the other end of the safety rope 11 to complete the rearrangement of the safety rope 11.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
