Technical Field
[0001] This utility model relates to the field of outdoor power distribution cabinet technology, specifically an outdoor power distribution cabinet with a waterproof structure. Background Technology
[0002] Outdoor power distribution cabinets are located in complex environments. During heavy rain, poor drainage can cause water levels to rise continuously, and rainwater can seep into the cabinet through gaps, damaging the electronic components and causing significant losses.
[0003] There are many types of existing outdoor distribution cabinets, but in the face of heavy rain, some rainwater can still seep into the cabinet, causing damage. To overcome this problem, a water-proof outdoor distribution cabinet with application number 2024105518769 is designed. It is equipped with a waterproof mechanism, a sealing mechanism, and a limiting mechanism. After excessive water submerges the base, the limiting mechanism releases the restriction on the waterproof mechanism. The waterproof mechanism then connects with the sealing mechanism and seals, enclosing the distribution cabinet body and preventing water from entering, thus achieving a good water-proof effect.
[0004] Although the above-mentioned device can solve the purpose of waterproofing the bottom, some rainwater will still flow into the inside of the distribution cabinet through the heat dissipation vents, which may cause the electrical components inside the distribution cabinet to come into contact with the water source, resulting in a short circuit and affecting the normal use of the distribution cabinet.
[0005] Therefore, we proposed that an outdoor power distribution cabinet with a waterproof structure can effectively solve the above problems. Utility Model Content

[0012] As a preferred technical solution of this application, the outer side of the connecting gear is rotatably disposed on the outer side of the outdoor power distribution cabinet body, and two sets of the connecting gear are symmetrically distributed about the vertical center line of the outdoor power distribution cabinet body. The heat dissipation plate is rotatably disposed at the lower end of the left and right walls of the outdoor power distribution cabinet body.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This outdoor power distribution cabinet with a waterproof structure is equipped with a lifting mechanism. The operation of the lifting mechanism can raise the outdoor power distribution cabinet body to the top position of the fixed base. Furthermore, when the height of the outdoor power distribution cabinet body is adjusted, the connecting gear and the mating rack on the back of the outdoor power distribution cabinet body can mesh, thereby enabling the closing mechanism to drive the heat dissipation plate to close.

[0024] Please see Figures 1-6 This utility model provides the following technical solution; Embodiment 1: To avoid the bottom of the outdoor distribution cabinet body 1 coming into contact with water on the ground, thereby preventing rainwater from seeping into the interior of the outdoor distribution cabinet body 1 through the bottom, please refer to the attached... Figure 1 - Appendix Figure 5 The system includes an outdoor power distribution cabinet body 1, which houses electrical components 2. A cover plate 3 is hinged to one side of the outdoor power distribution cabinet body 1. A waterproof frame 4 is fixed to the top of the outdoor power distribution cabinet body 1. The bottom of the outdoor power distribution cabinet body 1 is mounted on top of a fixed base 5. A fixed box 6 is fixed to the top of the fixed base 5. A lifting mechanism is installed inside the fixed box 6 to allow the outdoor power distribution cabinet body 1 to change height at the top of the fixed base 5. The lifting mechanism includes a drive motor 7 fixed to the top of the fixed box 6, with the output end of the drive motor 7 fixed... At the top and bottom of the threaded rod 8, it is rotatably positioned inside the fixed box 6. A threaded connecting block 9 is also threadedly connected to the outside of the threaded rod 8, and the outer end of the threaded connecting block 9 is fixed to the back of the outdoor distribution cabinet body 1. The drive motor 7 is located inside the waterproof cover, and the output end of the drive motor 7 rotatably extends into the interior of the fixed box 6. The output end of the drive motor 7 is also fixed to the top of the threaded rod 8. The back of the outdoor distribution cabinet body 1 is attached to the front of the fixed box 6. The fixed box 6 has a single opening. The threaded connecting block 9 forms a lifting mechanism between the threaded rod 8 and the interior of the fixed base 5.
[0025] When it is necessary to raise the outdoor distribution cabinet body 1, the drive motor 7 on the top of the fixed box 6 is started, which drives the threaded rod 8 to rotate. The outer side of the threaded rod 8 can drive the threaded connecting block 9 to adjust the height. At this time, the outer side of the threaded connecting block 9 is fixedly connected to the back of the outdoor distribution cabinet body 1. The threaded connecting block 9 can drive the outdoor distribution cabinet body 1 to adjust its height outside the fixed box 6. At this time, the bottom of the outdoor distribution cabinet body 1 is separated from the top of the fixed base 5. The height adjustment of the outdoor distribution cabinet body 1 can prevent water from the ground from seeping into the interior of the outdoor distribution cabinet body 1.
[0026] Example 2: To address the issue that some rainwater still seeps into the interior of current power distribution cabinets during heavy rain, potentially causing short circuits due to water contact with internal electrical components and affecting normal operation, please refer to the attached... Figure 1 - Appendix Figure 4 and attached Figure 6 The lifting mechanism enables the operation of the closing mechanism, and the driving of the closing mechanism enables the heat dissipation plates 13 located on the left and right sides of the outdoor power distribution cabinet body 1 to close and rotate. The closing mechanism includes a mating rack 10 fixedly connected to the left and right sides of the fixed box 6. The outer side of the mating rack 10 is meshed with the outer side of the connecting gear 11. The outer center of the connecting gear 11 is fixed to the inner side of the connecting shaft 12. The inner end of the connecting shaft 12 is fixed through and fixed to the center of the side of the heat dissipation plate 13. The other end of the connecting shaft 12 is rotatably located inside the outdoor power distribution cabinet body 1. The outer side of the heat dissipation plate 13 is synchronously connected to other heat dissipation plates 13 through the sprocket and chain transmission assembly 14. The outer side of the connecting gear 11 is rotatably located on the outer side of the outdoor power distribution cabinet body 1. There are two sets of connecting gears 11 symmetrically distributed about the vertical center line of the outdoor power distribution cabinet body 1. The heat dissipation plates 13 are rotatably located at the lower ends of the left and right walls of the outdoor power distribution cabinet body 1.
[0027] After the height of the outdoor distribution cabinet body 1 is removed from the top position of the fixed base 5, the outer side of the connecting gear 11 will also mesh with the mating rack 10, so that the connecting gear 11 rotates at the back position of the outdoor distribution cabinet body 1. Since the outer side of the connecting gear 11 is fixedly connected to the connecting shaft 12, the connecting shaft 12 can rotate inside the outdoor distribution cabinet body 1, so that the heat dissipation plate 13 rotates inside the outdoor distribution cabinet body 1. At the same time, the sprocket and chain drive assembly 14 set at the outer end of the connecting shaft 12 will also run, so that the sprocket and chain drive assembly 14 drives the other heat dissipation plates 13 to rotate. Through the above settings, the heat dissipation plate 13 can close the side of the outdoor distribution cabinet body 1, thereby preventing some rainwater from flowing into the inside of the distribution cabinet through the heat dissipation vent, which could cause the electrical components inside the distribution cabinet to come into contact with the water source and cause a short circuit.
