DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-Figure 3 As shown, the embodiment of the utility model proposes a distribution box for a high-voltage lithium battery energy storage system, comprising:

[0024] The box body 1 has a door 20 rotatably disposed at the front end thereof, and a positioning assembly is disposed at the inner top of the box body 1;

[0025] The positioning assembly includes a threaded barrel 8, a third threaded rod 9, a top plate 10 and a lifting plate 11. The threaded barrel 8 penetrates the inner top of the box body 1 and is rotatably arranged. The third threaded rod 9 extends into the threaded barrel 8 and is threadedly connected. The top plate 10 is fixedly arranged at the bottom of the third threaded rod 9. The lifting plate 11 is arranged below the top plate 10. The lifting plate 11 and the top plate 10 are both slidably arranged against the inner wall of the box body 1, so that the top plate 10 and the lifting plate 11 can only move up and down in the box body 1, and cannot rotate. A guide assembly is arranged between the lifting plate 11 and the top plate 10.

[0026] The guide assembly includes two guide rods and two springs 12. The two guide rods are fixedly arranged on the lifting plate 11 in parallel. The two guide rods are slidably arranged through the top plate 10. The two guide rods guide the lifting plate 11. The tops of the two guide rods are fixedly provided with limit blocks. The two limit blocks limit the two guide rods. The two springs 12 are fixedly arranged on the lifting plate 11. The tops of the two springs 12 are fixedly arranged at the bottom of the top plate 10. The two guide rods are respectively penetrated by the two springs 12 and are movably arranged. The two springs 12 can exert a pressure on the lifting plate 11, thereby exerting a pressure on the controller body, making the installation of the controller body more stable and increasing practicality.

[0027] The clamping assembly includes a first threaded rod 2, a second threaded rod 3, two sliders 5 and two clamping blocks 7. One end of the first threaded rod 2 is fixedly arranged on one end of the second threaded rod 3. The outer end of the first threaded rod 2 is rotatably arranged on the inner wall of the box body 1. The outer end of the second threaded rod 3 is fixedly arranged with a round rod 4. The round rod 4 is rotatably arranged on the inner wall of the box body 1. The two sliders 5 are both slidably opposed to the inner bottom of the box body 1, so that the two sliders 5 can only slide back and forth on the inner bottom of the box body 1 and cannot rotate. The first threaded rod 2 and the second threaded rod 3 are respectively threadedly connected through the sliders 5 on the same side;

[0028] The two sliders 5 are fixedly provided with a moving plate 6, and the two clamping blocks 7 are respectively fixedly provided at the top outer ends of the two moving plates 6. The bottom of the lifting plate 11 and the tops of the two moving plates 6 are fixedly provided with anti-skid rubber pads. A controller body is provided between the lifting plate 11 and the moving plates 6. The multiple anti-skid rubber pads are all set against the controller body, so that the fixation of the controller body is more stable and the controller body is prevented from sliding.

[0029] A transmission assembly is provided on the round rod 4, and the transmission assembly includes a shaft 13, a belt 15, a first bevel gear 16 and a second bevel gear 17. The shaft 13 passes through the top of the box body 1 and is rotatably arranged. A crank is fixedly arranged on the top of the shaft 13, and rotating the crank can drive the shaft 13 to rotate. Pulleys 14 are fixedly arranged on the threaded cylinder 8 and the shaft 13. The two pulleys 14 are transmitted through the belt 15. The first bevel gear 16 is fixedly arranged at the bottom of the shaft 13, and the second bevel gear 17 is fixedly arranged on the round rod 4. The first bevel gear 16 is meshed and connected with the second bevel gear 17, so that the first bevel gear 16 can drive the second bevel gear 17 to rotate;

[0030] It also includes a heat dissipation component, which includes a fan 18 installed on one side of the box body 1. The fan 18 is fixedly arranged through the box body 1. A dustproof net is fixedly arranged on the outer end of the fan 18. The dustproof net can prevent dust from entering the box body 1 to avoid affecting the operation of the controller body. A plurality of heat dissipation holes 19 are arranged through the other side of the box body 1.

[0031] The detailed working process of the utility model is as follows:

[0032] 1. During installation, the staff first places the controller body on the two moving plates 6, and then turns the crank to drive the shaft 13 to rotate. The shaft 13 drives the round rod 4 to rotate through the first bevel gear 16 and the second bevel gear 17. The round rod 4 drives the first threaded rod 2 and the second threaded rod 3 to rotate. The first threaded rod 2 and the second threaded rod 3 drive the corresponding slider 5 to move inward. The two sliders 5 drive the corresponding moving plates 6 and the clamping block 7 to move inward to clamp the controller body. At the same time, the shaft 13 drives the threaded cylinder 8 to rotate through the two pulleys 14 and the belt 15. The threaded cylinder 8 drives the top plate 10 to move downward through the third threaded rod 9. The top plate 10 drives the lifting plate 11 to move downward and resist the controller body. Continue to move downward, squeeze the two springs 12, and fix the controller body tightly. Finally, cover the box door 20, turn on the fan 18 for heat dissipation, and it can be used normally.

[0033] 2. During disassembly, the staff first turns off the fan 18, then opens the box door 20, and then rotates the crank in the opposite direction to drive the shaft 13 to reverse, the shaft 13 drives the threaded cylinder 8 and the round rod 4 to reverse, the threaded cylinder 8 drives the top plate 10 and the lifting plate 11 to move upward through the third threaded rod 9, and the controller body is loosened, the round rod 4 drives the first threaded rod 2 and the second threaded rod 3 to rotate in the opposite direction, and drives the two sliders 5 to move to both sides, the two sliders 5 drive the corresponding moving plates 6 and clamping blocks 7 to move to both sides, loosen the controller body, and finally take out the controller body.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
