AI Technical Summary
When the existing low-voltage distribution cabinet waterproof structure is raining, water vapor is likely to enter the cabinet through the heat dissipation port, resulting in damage to the electrical appliances.
A waterproof structure including a fixed seat, an elastic rubber sealing cover, a movable block, a semi-ring, a steel rope and a wedge plate is designed. When it rains, after the rain sensor senses the rainwater, it starts the waterproof servo motor to drive the winding roller to rotate. The steel rope is wound on the winding roller, and the movable block and seal cover move upwards, covering outside the heat dissipation port to prevent water and gas from entering.
It effectively prevents water and gas from entering the low-voltage distribution cabinet through the heat dissipation port during rain, protecting the electrical appliances inside the cabinet and ensuring the normal operation of the equipment.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figure 1-Figure 4As shown, a waterproof structure of a low-voltage distribution cabinet includes a cabinet body 1, heat dissipation ports 4 are provided on both sides of the cabinet body 1, and waterproof structures 7 are provided near the lower end of both sides of the cabinet body 1, and a waterproof structure 7 includes a fixing seat 8, the fixing seat 8 is fixed to one side of the cabinet body 1, an elastic rubber sealing cover 9 is fixedly installed on the upper end of the fixing seat 8, and a movable block 10 is fixedly connected to the upper end of the elastic rubber sealing cover 9, and a semicircular ring 12 is fixedly installed near the upper end of the movable block 10 near both sides, and the outer sleeve of the semicircular ring 12 is provided with a steel Rope 13, and a wedge plate 11 is fixedly installed on the upper end of the movable block 10. When it rains, the rain sensor 6 at the upper end of the awning 5 senses the rain and gives an electrical signal to the waterproof servo motor 19. After the waterproof servo motor 19 is started, it drives the winding roller 18 to rotate. After the steel rope 13 is wound on the winding roller 18, the movable block 10 moves upward, driving the elastic rubber sealing cover 9 to move upward so that it covers the outside of the heat dissipation port 4 to prevent water vapor from entering the interior of the cabinet 1 through the heat dissipation port 4 when it rains.
[0019] In this embodiment, an inclined groove 16 is provided at the rear end of the wedge plate 11, and three rubber inclined plates 17 are fixedly installed inside the inclined groove 16. The length of the wedge plate 11 is greater than the length of the heat dissipation port 4. The three rubber inclined plates 17 can prevent some rainwater from falling from one side of the cabinet 1 to the inside of the heat dissipation port 4.
[0020] In this embodiment, two T-slots 14 are provided on both sides of the cabinet body 1, and a T-block 15 is fixedly installed at the rear end of the movable block 10. The T-block 15 is movably engaged with the T-slot 14, so that the movable block 10 can be limited and can only move up and down, and will not be deviated to the left or right due to the upward pulling of the steel rope 13.
[0021] In this embodiment, a base 3 is fixedly installed at the lower end of the cabinet 1, and a sealing door 2 is movably installed at the front end of the cabinet 1. A canopy 5 is fixedly installed at the upper end of the cabinet 1, and a rain sensor 6 is arranged outside the canopy 5.
[0022] In this embodiment, waterproof servo motors 19 are fixedly installed on both sides of the cabinet 1 near the top, a winding roller 18 is fixedly installed on the outside of the output shaft of the waterproof servo motor 19, and one end of the steel rope 13 is tied to the outside of the winding roller 18.
[0023] The implementation principle of the waterproof structure of a low-voltage distribution cabinet in an embodiment of the present application is as follows: when it rains, the rain sensor 6 at the upper end of the awning 5 senses rain and then gives an electrical signal to the waterproof servo motor 19. After the waterproof servo motor 19 is started, it drives the winding roller 18 to rotate. After the steel rope 13 is wound around the winding roller 18, the movable block 10 moves upward, driving the elastic rubber sealing cover 9 to move upward so that it covers the outside of the heat dissipation port 4 to prevent moisture from entering the interior of the cabinet 1 through the heat dissipation port 4 when it rains. The three rubber inclined plates 17 can prevent part of the rain from falling from one side of the cabinet 1 to the interior of the heat dissipation port 4. The T-block 15 is movably engaged with the T-slot 14, so that the movable block 10 can be limited and can only move up and down, and will not deviate left and right due to the upward pulling of the steel rope 13.
