A new type of explosion-proof lithium battery storage box

Abstract

This utility model discloses a novel explosion-proof lithium battery storage box, comprising: a storage box body; two mounting plates, both fixedly connected to the inner wall of the storage box body; a sliding plate slidably connected between the two mounting plates; a clamping plate slidably connected to the sliding plate; and a plurality of buffer springs, all fixedly connected to the sliding plate, with the other end of each buffer spring fixedly connected to one side of the clamping plate. Through the structural design of the buffer springs, cutter, and pressure-relieving bolts, this utility model ensures that when a battery inside the storage box explodes, the clamping plate slides on the sliding plate, and the buffer springs buffer the impact force of the explosion. When the springs reach their maximum buffering capacity, the clamping plate and the sliding plate slide on the mounting plate. During this sliding process, the cutter cuts the pressure-relieving bolts, converting the impact force into shear force, further buffering the impact force, thereby effectively reducing the explosion intensity and minimizing harm to surrounding personnel, equipment, and buildings.

Description

Technical Field

[0001] This utility model relates to the field of battery storage technology, specifically to a novel explosion-proof lithium battery storage box. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They have advantages such as high energy density, long service life, and low self-discharge rate, and are widely used in automobiles, energy storage, electronic products, and aerospace. However, overcharging, over-discharging, and short circuits during use can cause lithium-ion batteries to catch fire or explode. Therefore, storage boxes are used to isolate lithium-ion batteries from the surrounding environment. Even if the lithium-ion batteries inside the box explode or catch fire, it can effectively prevent the flames and shock waves from spreading outward, reducing the harm to surrounding personnel, equipment, and buildings.

[0003] Currently, most lithium battery storage boxes are equipped with buffer springs to slow down the propagation speed and intensity of the pressure wave from a battery explosion. However, the impact force of a lithium battery explosion is relatively large, and the buffer springs can only absorb a small portion of the impact force. Most of the impact force still acts on the box body and cannot effectively reduce the propagation speed and intensity of the explosion pressure wave. Utility Model Content

[0004] The purpose of this invention is to provide a novel explosion-proof lithium battery storage box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel explosion-proof lithium battery storage box, comprising: a storage box body; two mounting plates, both fixedly connected to the inner wall of the storage box body; a sliding plate slidably connected between the two mounting plates; a clamping plate slidably connected to the sliding plate; a plurality of buffer springs, all fixedly connected to the sliding plate, with the other end of each buffer spring fixedly connected to one side of the clamping plate; a cutter fixedly connected to the sliding plate; and a plurality of pressure relief bolts threadedly connected to the mounting plate; the pressure relief bolts and the cutter are configured to cooperate so that when the sliding plate is subjected to excessive impact, the cutter cuts the pressure relief bolts.

[0006] As a further preferred embodiment of this technical solution, it also includes: several explosion-proof solenoid valves, all installed on the storage tank body; and a gas sensor installed inside the storage tank body.

[0007] As a further preferred embodiment of this technical solution, it also includes: two explosion-proof meshes, respectively installed in two heat dissipation channels of the storage box body; and a fan, installed in the heat dissipation channel of the storage box body.

[0008] As a further preferred embodiment of this technical solution, it also includes: a plurality of protective plates, all disposed on the inner wall of the storage box body; the protective plates are made of ceramic fiber.

[0009] As a further preferred embodiment of this technical solution, it also includes: two explosion-proof meshes, which are respectively fixedly connected to the two mounting plates.

[0010] As a further preferred embodiment of this technical solution, it also includes: a plurality of reinforcing ribs, all fixedly connected to the mounting plate, and the reinforcing ribs being fixedly connected to the inner wall of the storage box body.

[0011] As a further preferred embodiment of this technical solution, it also includes: a disassembly plate, which is fixed to the storage tank body by multiple bolts, and the bottom of the disassembly plate is fixedly connected to the bottom of the gas sensor.

[0012] This utility model provides a novel explosion-proof lithium battery storage box, which has the following beneficial effects:

[0013] This invention utilizes a structural design incorporating a buffer spring, a cutter, and a pressure relief bolt. When the battery inside the storage box explodes, the clamping plate slides on the sliding plate, and the buffer spring cushions the impact of the explosion. When the spring reaches its maximum cushioning capacity, the clamping plate and the sliding plate slide on the mounting plate. During this sliding process, the cutter cuts the pressure relief bolt, converting the impact force into shearing force, further cushioning the impact force. This effectively reduces the intensity of the explosion and minimizes harm to surrounding personnel, equipment, and buildings. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 - Figure 4 As shown, in this embodiment, a novel explosion-proof lithium battery storage box includes: a storage box body 1; two mounting plates 6, both fixedly connected to the inner wall of the storage box body 1; a sliding plate 10, slidably connected between the two mounting plates 6; a clamping plate 11, slidably connected to the sliding plate 10; a plurality of buffer springs 14, all fixedly connected to the sliding plate 10, and the other end of the buffer springs 14 is fixedly connected to one side of the clamping plate 11; a cutter 15, fixedly connected to the sliding plate 10; and a plurality of pressure relief bolts 12, all threadedly connected to the mounting plate 6. The pressure relief bolts 12 and the cutter 15 are configured to cooperate so that when the sliding plate 10 is subjected to excessive impact, the cutter 15 cuts off the pressure relief bolts 12.

[0021] Through the structural design of the buffer spring 14, the cutter 15, and the pressure relief bolt 12, when the battery inside the storage tank body 1 explodes, the clamping plate 11 slides on the sliding plate 10, and the buffer spring 14 buffers the impact force of the explosion. When the spring reaches its maximum buffering capacity, the clamping plate 11 and the sliding plate 10 will slide on the mounting plate 6. During the sliding process, the cutter 15 cuts the pressure relief bolt 12, converting the impact force into shear force, further buffering the impact force, thereby effectively reducing the explosion intensity and reducing the harm to surrounding personnel, equipment, and buildings. The clamping plate 11, the buffer spring 14, the mounting plate 6, and the pressure relief bolt 12 are also installed on the other side of the inner wall of the storage tank body 1, and the two are symmetrical to each other.

[0022] like Figure 1 and Figure 2 As shown, it also includes: several explosion-proof solenoid valves 3, all installed on the storage tank body 1; and a gas sensor 8, installed inside the storage tank body 1.

[0023] The gas sensor 8 monitors the gas situation inside the storage tank 1 in real time. When hazardous gas is generated inside the storage tank 1, the gas sensor 8 controls the explosion-proof solenoid valve 3. The valve of the explosion-proof solenoid valve 3 opens, and the gas is discharged to relieve pressure. The explosion-proof solenoid valve 3 is composed of components such as an electromagnetic coil, valve core, and valve seat. When the electromagnetic coil is energized, it generates a magnetic field that attracts the valve core to move, thereby opening or closing the valve to control the fluid passage. When the power is off, the valve core returns to its initial position under the action of spring force or other reset mechanism, cutting off the fluid passage.

[0024] like Figure 1 and Figure 2As shown, it also includes: two explosion-proof meshes 2, which are respectively installed in the two heat dissipation channels of the storage box body 1; and a fan 7, which is installed in the heat dissipation channel of the storage box body 1. Through the structural design of the fan 7, the heat dissipation efficiency inside the storage box body 1 can be improved, preventing the risk of battery explosion due to overheating.

[0025] like Figure 2 As shown, it also includes: several protective plates 5, all of which are installed on the inner wall of the storage box body 1; the protective plates 5 are made of ceramic fiber, and when a fire occurs, the protective plates 5 can form a barrier to slow down or prevent the spread of flames to the battery.

[0026] like Figure 2 As shown, it also includes: two explosion-proof nets 13, which are fixedly connected to two mounting plates 6 respectively. When the shock wave generated by the explosion will spread rapidly in the storage tank body 1 and generate high pressure, the explosion-proof nets 13 can buffer and disperse the explosion pressure to a certain extent. Through its own deformation and reflection and absorption of the shock wave, it reduces the damage of the explosion to the overall structure of the storage tank.

[0027] like Figure 2 - Figure 4 As shown, it also includes: several reinforcing ribs 9, all fixedly connected to the mounting plate 6, and the reinforcing ribs 9 are fixedly connected to the inner wall of the storage box body 1; the structural design of the reinforcing ribs 9 improves the connection strength between the mounting plate 6 and the storage box body 1, and prevents the impact force from being too great, causing the mounting plate 6 to deform and causing the sliding direction of the sliding plate 10 to change.

[0028] like Figure 1 and Figure 2 As shown, it also includes: a disassembly plate 4, which is fixed to the storage tank body 1 by multiple bolts. The bottom of the disassembly plate 4 is fixedly connected to the bottom of the gas sensor 8. The structural design of the disassembly plate 4 allows the storage tank body 1 to be opened, making it convenient to repair the structure inside the storage tank body 1.

[0029] This utility model provides a novel explosion-proof lithium battery storage box, the specific working principle of which is as follows:

[0030] When placing lithium batteries into the storage box body 1, the disassembly plate 4 is first opened, and the lithium batteries are placed between the two clamping plates 11. The two clamping plates 11 serve to fix the lithium batteries. After installation, the disassembly plate 4 is installed on the storage box body 1. The gas sensor 8 installed on the storage box body 1 monitors the situation inside the storage box body 1 in real time. When the lithium battery emits dangerous gas, the gas sensor 8 controls the explosion-proof solenoid valve 3. The valve of the explosion-proof solenoid valve 3 opens, and the gas is discharged to relieve pressure. When the lithium battery explodes, the impact force of the explosion pushes the clamping plate 11 to slide on the sliding plate 10. The buffer spring 14 buffers the impact force of the explosion. When the spring reaches its maximum buffering capacity, the clamping plate 11 and the sliding plate 10 will slide on the mounting plate 6. During the sliding process, the cutter 15 cuts the pressure relief bolt 12, converting the impact force into shear force, further buffering the impact force, thereby effectively reducing the explosion intensity and reducing the harm to surrounding personnel, equipment and buildings.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
