Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically to a protective device for energy storage batteries. Background Technology

[0002] Energy storage batteries are key devices for storing electrical energy in renewable energy systems. They are mainly used in solar power generation equipment and wind power generation equipment. With the continuous development of energy storage technology, energy storage batteries have been widely used in many fields. However, energy storage batteries face many potential risks during use, among which collision and friction are common factors that cause damage.

[0003] Existing protective measures for energy storage batteries have many shortcomings. Energy storage batteries typically have a relatively regular shape, with eight sharp corners on their outer sides. During the handling, installation, and use of energy storage batteries, these corners are highly susceptible to impact or friction. Due to the lack of an effective protective structure, the sharp corners are easily damaged by direct impact or scratches, leading to damage to the internal battery cells, which in turn shortens the lifespan of the energy storage battery and increases operating costs. Therefore, a protective device for energy storage batteries is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a protection device for energy storage batteries to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy storage battery protection device, comprising an energy storage battery body, wherein the energy storage battery body has eight apex corners on its outer side, and corner protectors are connected to the outer side of each apex corner;

[0006] A protective component is provided on one side of the corner guard, which is used to protect the outside of the energy storage battery body.

[0007] One side of the corner protector is provided with a connecting component for assembling and disassembling the protective components;

[0008] The protective assembly includes two sets of first connecting rods, second connecting rods, third connecting rods and fourth connecting rods. One set of first connecting rods, second connecting rods, third connecting rods and fourth connecting rods has a plurality of first sliding grooves on one side, while the other set of first connecting rods, second connecting rods, third connecting rods and fourth connecting rods has a limit groove on one side.

[0009] A metal rod is inserted into the inner side of the first groove, and a limit block is fixed to the outer side of the metal rod.

[0010] Preferably, each of the aforementioned metal rods has a screw fixed to its bottom, the outer side of which is threaded to the inner side of the limiting groove, and the diameter of the screw is smaller than the diameter of the metal rod.

[0011] Preferably, one end of the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod is hinged to one side of the adjacent corner protector.

[0012] Preferably, one side of the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod is located on the outside of the energy storage battery body.

[0013] When the screw leaves the inner side of the limiting groove, the metal rod is in a detachable state.

[0014] Preferably, the connecting assembly includes two fixing brackets, one side of which is provided with a second sliding groove and a connecting groove, one end of the first connecting rod is adapted to the inner side of the connecting groove, and one side of the first connecting rod is provided with a locking groove.

[0015] Preferably, as described above, a slide plate is slidably connected to the inner side of the second slide groove, and a pull rod and a locking rod are fixed on both sides of the slide plate respectively;

[0016] When the locking rod is inserted into the lock groove, the protective component is in the installed state; when the locking rod is removed from the lock groove, the protective component is in the disassembled state.

[0017] Preferably, as described above, a cover plate is bolted to one side of the fixing frame, and a spring is connected between the sliding plate and the second slide groove.

[0018] Preferably, one side of the fixing frame is fixed to one side of the corner protector, and the outer side of the pull rod extends through one side of the fixing frame.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0020] First, the eight corners of the outer side of the energy storage battery body are each covered with a corner protector. The corner protector directly contacts the corner and forms a protective cover. When the energy storage battery body is hit or rubbed, the corner protector will first contact the external object, avoiding damage to the sharp corners due to direct impact or scratch, thus extending the service life of the energy storage battery body.

[0021] Second, when an external object impacts the battery, the object will first contact the metal rod. The metal rod is threadedly connected to the limiting groove via a bottom screw and inserted into the first sliding groove, forming a protective structure spanning the side of the battery body. This ensures that the metal rod bears the force first, preventing the object from directly contacting the battery body, effectively buffering and isolating it, and reducing the risk of damage to the battery body due to impact. When the metal rod is damaged due to impact, the screw can be disengaged from the limiting groove by rotating the hexagonal nut at the top of the metal rod, allowing the metal rod to be pulled out of the first sliding groove for individual replacement without disassembling the entire protective assembly. This greatly simplifies the maintenance process and reduces maintenance costs and time.

[0022] Third, when it is necessary to disassemble the protective component, simply pull the lever, and the slide plate will slide in the second slide groove and compress the spring, thereby driving the locking rod to disengage from the locking groove of the first connecting rod. At this time, the protective component can be easily removed from the outside of the energy storage battery body, making the disassembly process of the protective component simple and easy to operate without the need for complicated tools.

[0033] Example

[0034] Please see Figure 1-6 This utility model provides a technical solution: an energy storage battery protection device, including an energy storage battery body 1, with eight apex corners on the outer side of the energy storage battery body 1, and corner protectors 3 connected to the outer side of each apex corner. The corner protectors 3 are wrapped around the apex corners to prevent the eight sharp corners on the outer side of the energy storage battery body 1 from contacting objects and causing damage. The corner protectors 3 are made of plastic and have rounded corners on their surfaces. A protective component 2 is provided on one side of the corner protector 3, which is used to protect the outer side of the energy storage battery body 1. A connecting component 5 for assembling and disassembling the protective component 2 is provided on one side of the corner protector 3.

[0035] Protective component 2 includes two sets of first connecting rods 22, second connecting rods 23, third connecting rods 24, and fourth connecting rods 25. A hexagonal nut is fixed to one end of each metal rod 21. The first connecting rods 22, second connecting rods 23, third connecting rods 24, and fourth connecting rods 25 are made of metal. One set of first connecting rods 22, second connecting rods 23, third connecting rods 24, and fourth connecting rods 25 has several first sliding grooves 28 on one side, while the other set of first connecting rods 22, second connecting rods 23, third connecting rods 24, and fourth connecting rods 25 has limited... The slot 27; a metal rod 21 is inserted into the inner side of the first sliding groove 28. The number of metal rods 21 can be set according to the actual use scenario. When an external object hits, the metal rod 21 will bear the impact force first and undergo elastic deformation, converting kinetic energy into deformation energy, thus avoiding the force from being directly transmitted to the energy storage battery body 1. A limit block 29 is fixed on the outside of the metal rod 21, so that the external object will contact the metal rod 21 first, thus avoiding the object from directly hitting the energy storage battery body 1. At the same time, the protective component 2 does not completely block the energy storage battery body 1, thus avoiding affecting the heat dissipation of the energy storage battery body 1.

[0036] Each metal rod 21 has a screw 26 fixed at its bottom. The outer thread of the screw 26 is connected to the inner side of the limiting groove 27. The diameter of the screw 26 is smaller than the diameter of the metal rod 21. If the metal rod 21 is deformed due to impact, the screw 26 can be rotated by the hexagonal nut to disengage it from the limiting groove 27, so that the damaged metal rod 21 can be replaced individually. One end of the first connecting rod 22, the second connecting rod 23, the third connecting rod 24 and the fourth connecting rod 25 are respectively hinged to one side of the adjacent corner guard 3. The two ends of each connecting rod are respectively hinged to one side of two adjacent corner guards 3.

[0037] One side of the first connecting rod 22, the second connecting rod 23, the third connecting rod 24, and the fourth connecting rod 25 is located on the outside of the energy storage battery body 1; one end of the metal rod 21 is inserted into the first sliding groove 28, and the other end is threadedly connected to the limiting groove 27 through the screw 26. When the screw 26 leaves the inside of the limiting groove 27, the metal rod 21 is in a detachable state. When the metal rod 21 is damaged by external impact, it is only necessary to rotate the hexagonal nut on the top of the metal rod 21 to make the screw 26 leave the limiting groove 27, and the deformed metal rod 21 can be replaced.

[0038] The connecting assembly 5 includes two fixing brackets 51. Each fixing bracket 51 has a second sliding groove 54 and a connecting groove 57 on one side. One end of the first connecting rod 22 is adapted to the inner side of the connecting groove 57. A locking groove 58 is provided on one side of the first connecting rod 22. A sliding plate 55 is slidably connected to the inner side of the second sliding groove 54. A pull rod 52 and a locking rod 56 are fixed on both sides of the sliding plate 55, respectively. During installation, the pull rod 52 is pulled outward to retract the locking rod 56. After inserting the first connecting rod 22 into the connecting groove 57, the pull rod 52 is released, and the spring 53 pushes the locking rod 56 into the locking groove 58 to achieve locking. During disassembly, the pull rod 52 is pulled outward to drive the locking rod 56 out of the locking groove 58, so that the protective assembly 2 can be quickly separated.

[0039] When the locking rod 56 is inserted into the inner side of the locking groove 58, the protective component 2 is in the installed state. When the locking rod 56 is removed from the inner side of the locking groove 58, the protective component 2 is in the disassembled state. In this embodiment, the lengths of the first connecting rod 22, the second connecting rod 23, the third connecting rod 24 and the fourth connecting rod 25 can be set according to the size of the energy storage battery body 1. First, connect the remaining parts, and finally, under the action of the connecting component 5, the first connecting rod 22 is used to make the protective component 2 fit on the outside of the energy storage battery body 1. The cover plate 4 is bolted to one side of the fixing frame 51. A spring 53 is connected between the sliding plate 55 and the second sliding groove 54. The spring 53 can be replaced by removing the cover plate 4. One side of the fixing frame 51 is fixed to one side of the corner guard 3, and the outer side of the pull rod 52 moves through one side of the fixing frame 51.

[0040] Working principle: The eight corners of the outer side of the energy storage battery body 1 are respectively wrapped with corner protectors 3. The corner protectors 3 directly contact the corners and form a wrap. When the energy storage battery body 1 is hit or rubbed, the corner protectors 3 will first contact the external object to avoid the sharp corners being damaged by direct impact or scratch, thus playing a basic role in corner protection.

[0041] When an external object impacts the battery, the object will first contact the metal rod 21. The metal rod 21 is threadedly connected to the limiting groove 27 via the bottom screw 26, and the metal rod 21 is inserted into the first sliding groove 28 to form a protective structure spanning the side of the energy storage battery body 1. When an external object impacts the energy storage battery body 1, the metal rod 21 will be subjected to force first, preventing the object from directly contacting the energy storage battery body 1, thus playing a buffering and isolation role.

[0042] The protective component 2 adopts a rod-shaped structure instead of a closed panel, and the connecting rod and the outer side of the energy storage battery body 1 are separated. This can block the impact and retain a large amount of heat dissipation space to avoid affecting the heat dissipation of the energy storage battery body 1. When the metal rod 21 is damaged by impact, the screw 26 can be disengaged from the limiting groove 27 by rotating the hexagonal nut on the top of the metal rod 21. At this time, the metal rod 21 can be pulled out from the first sliding groove 28 for individual replacement without disassembling the entire protective component 2.

[0043] When the lever 52 is pulled, the slide plate 55 slides in the second slide groove 54 and compresses the spring 53, causing the locking rod 56 to disengage from the locking groove 58 of the first connecting rod 22. At this time, the protective component 2 can be removed from the outside of the energy storage battery body 1.

[0044] During actual installation, the lengths of the first connecting rod 22, the second connecting rod 23, the third connecting rod 24, and the fourth connecting rod 25 can be limited according to the size of the energy storage battery body 1. First, connect the remaining parts. Finally, under the action of the connecting component 5, rotate the first connecting rod 22 to the inside of the connecting groove 57. Then, pull the pull rod 52 so that the locking groove 58 is located at the top of the locking rod 56. Release the pull rod 52, and under the elastic force of the spring 53, push the locking rod 56 into the inside of the locking groove 58, so that the protective component 2 is sleeved on the outside of the energy storage battery body 1, completing the installation.

[0045] In summary, the eight corners of the outer side of the energy storage battery body 1 are each covered with a corner protector 3. The corner protector 3 directly contacts the corner and forms a cover. When the energy storage battery body 1 is subjected to collision or friction, the corner protector 3 will first contact the external object, avoiding damage to the sharp corner due to direct impact or scratch, thus extending the service life of the energy storage battery body 1.

[0046] When an external object impacts the battery, it first contacts the metal rod 21. The metal rod 21 is threadedly connected to the limiting groove 27 via the bottom screw 26 and inserted into the first sliding groove 28, forming a protective structure spanning the side of the energy storage battery body 1. This allows the metal rod 21 to bear the force first, preventing the object from directly contacting the energy storage battery body 1, effectively buffering and isolating it, and reducing the risk of damage to the energy storage battery body 1 due to impact. When the metal rod 21 is damaged due to impact, the screw 26 can be disengaged from the limiting groove 27 by rotating the hexagonal nut at the top of the metal rod 21, and the metal rod 21 can then be pulled out of the first sliding groove 28 for individual replacement without disassembling the entire protective assembly 2. This greatly simplifies the maintenance process and reduces maintenance costs and time.

[0047] When it is necessary to disassemble the protective component 2, simply pull the lever 52, and the slide plate 55 will slide in the second slide groove 54 and compress the spring 53, thereby driving the locking lever 56 to disengage from the locking groove 58 of the first connecting rod 22. At this time, the protective component 2 can be easily removed from the outside of the energy storage battery body 1, making the disassembly process of the protective component 2 simple and easy to operate, without the need for complicated tools.
