Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, and specifically to an energy storage battery protection device. Background Technology

[0002] Energy storage batteries mainly refer to batteries used in solar power generation equipment, wind power generation equipment, and renewable energy storage. After being fully charged, these batteries are placed in packaging boxes and transported out.

[0003] Currently, after the energy storage battery is placed in the packaging box, the screw drives the clamping plate to move and clamp the energy storage battery. However, this clamping method is a rigid clamping. When the packaging box shakes or bumps during transportation, the impact force on the packaging box can be directly transmitted to the energy storage battery through the clamping plate, causing damage to the internal components of the energy storage battery and affecting its use. Although cushioning material is placed in the packaging box, the cushioning material only partially absorbs the impact force on the packaging box and cannot buffer the impact force transmitted to the energy storage battery through the clamping plate.

[0017] This utility model provides a protective device for energy storage batteries. It is equipped with a protective mechanism, in which four L-shaped plates can clamp the four corners of the energy storage battery, increasing the clamping stability of the energy storage battery. Moreover, the clamping method is a flexible clamping.

[0018] This utility model provides a protective device for energy storage batteries. It is equipped with a moving mechanism. When the crossbar is rotated in the forward direction, the screw is driven to rotate in the reverse direction through the first bevel gear and the second bevel gear, so that the circular plate can move downward.

[0030] See attached document Figure 1-5 This utility model provides a protection device for energy storage batteries, comprising the following structure:

[0031] Box base 1, with box cover 19 fixedly connected to the upper end of box base 1 by multiple bolts. The inner wall of one side of box cover 19 is open, so that the positive and negative terminals of the energy storage battery are aligned with the opening, avoiding damage to the positive and negative terminals of the energy storage battery during packaging.

[0032] The protective mechanism includes four sliding grooves 2 on the upper end of the box base 1. Each of the four sliding grooves 2 has a slider 3 slidably connected to its inner wall. Each of the four sliders 3 has an L-shaped plate 4 fixedly connected to its upper end. Each of the L-shaped plates 4 has a groove 5 on its side wall that is close to each other. Each of the two grooves 5 has a buffer plate 6 slidably connected to its inner wall. The side wall of the buffer plate 6 is elastically connected to the inner wall of the groove 5 through multiple damping spring dampers 7.

[0033] like Figure 3 As shown, four L-shaped plates 4 are located at the four corners of the housing 1, which allows the four L-shaped plates 4 to clamp the four corners of the energy storage battery, increasing the clamping stability of the energy storage battery. Moreover, this clamping method is a flexible clamping. When the housing 1 shakes or bumps during transportation, the multiple damping spring shock absorbers 7 located on the four L-shaped plates 4 can absorb and buffer the impact force, preventing the impact force from acting on the energy storage battery and causing damage to the internal components of the energy storage battery, thus affecting its use.

[0034] The moving mechanism includes a moving cavity 8 formed within the housing 1, the top of which communicates with the bottom of four sliding grooves 2 (e.g., Figure 2 (As shown).

[0035] The moving mechanism also includes two rectangular rods 9 fixedly connected to the top of the moving cavity 8. The side walls of the two rectangular rods 9 are slidably connected to a circular plate 10. The four sliders 3 are fixedly connected to the side walls of the moving cavity 8 with first rods 11. The side walls of the circular plate 10 are rotatably connected to the side walls of the four first rods 11 respectively through four second rods 12.

[0036] A crossbar 14 is movably connected to the inner wall of the movable cavity 8 via a bearing. A first bevel gear 15 is fixedly connected to the side wall of the crossbar 14. A lead screw 13 is rotatably connected to the top of the movable cavity 8. The side wall of the lead screw 13 is threadedly connected to the side wall of the circular plate 10. A second bevel gear 16 is fixedly connected to the lower end of the lead screw 13. The first bevel gear 15 and the second bevel gear 16 mesh with each other.

[0037] Rotating the crossbar 14 in the forward direction causes the lead screw 13 to rotate in the reverse direction via the first bevel gear 15 and the second bevel gear 16, allowing the circular plate 10 to move downward. At this time, the circular plate 10 drives the four L-shaped plates 4 to move closer to each other via the four second rods 12 and the four first rods 11, clamping the energy storage battery located on the box base 1. This clamping method is simple to operate and does not require rotating the screw to move the clamping plate to clamp the energy storage battery as in the prior art.

[0038] The reverse rotation of the crossbar 14 causes the lead screw 13 to rotate in the forward direction, which in turn moves the circular plate 10 upward. Through the four second rods 12 and the four first rods 11, the four L-shaped plates 4 move closer to each other, thus releasing the energy storage battery.

[0039] The end of the crossbar 14 away from the first bevel gear 15 passes through the side wall of the housing 1 and is fixedly connected to a handwheel 17. The crossbar 14 is threaded on the side wall outside the housing 1, and a nut 18 is connected to the threaded side wall. The side wall of the nut 18 fits against the side wall of the housing 1, which can limit the rotation position of the crossbar 14, so that the four L-shaped plates 4 continuously and stably clamp the energy storage battery.

[0040] When packaging and transporting energy storage batteries, first place a foam board of the same size as the bottom of the energy storage battery on top of the box 1, and then place the energy storage battery on the foam board.

[0041] Then rotate nut 18 to separate from box 1, and rotate handwheel 17 in the forward direction. At this time, crossbar 14 rotates in the forward direction, and drives lead screw 13 to rotate in the reverse direction through first bevel gear 15 and second bevel gear 16, so that circular plate 10 moves downward. At this time, circular plate 10 drives four L-shaped plates 4 to move closer to each other through four second rods 12 and four first rods 11, clamping the four corners of the energy storage battery on box 1, increasing the clamping stability of the energy storage battery.

[0042] Then rotate nut 18 again to make the side wall of nut 18 fit tightly against the side wall of box base 1, limiting the rotation position of crossbar 14, so that the four L-shaped plates 4 continuously and stably clamp the energy storage battery.

[0043] Then, the staff can connect the box cover 19 to the box base 1 with multiple bolts to transport the box base 1. During the transportation of the box base 1, when it shakes or bumps, the multiple damping spring shock absorbers 7 located on the four L-shaped plates 4 can absorb and buffer the impact force, preventing the impact force from acting on the energy storage battery, causing damage to the internal components of the energy storage battery and affecting its use.

[0044] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
