[0001] The invention relates to the technical field of low-voltage power distribution cabinets, and in particular to a sealed and waterproof low-voltage power distribution cabinet. Background Art

[0002] Low-voltage distribution cabinets are products used to convert and configure electric energy. They are used in places where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in places where the load is concentrated and there are more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. It is the final equipment of the distribution system. However, the existing low-voltage distribution cabinets still have certain defects, such as:

[0003] The "anti-collision outdoor low-voltage power distribution cabinet" with application number CN202021180168.2 is not easy to seal and waterproof during use. When the low-voltage power distribution cabinet is placed outdoors and encounters rainy weather, rainwater can easily enter the cabinet through the door gaps and vents, making the internal electrical components easily damaged, affecting the service life, and is not conducive to ensuring the stable and effective use of the low-voltage power distribution cabinet;

[0053] 1. In rainy weather, rainwater falls into the water tank, and the water tank will move downward after being filled with rainwater.

[0071] The connecting plate 17 is sleeved on the outer side of the slide bar 9, and the connecting plate 17 is slidably connected to the slide bar 9, the positioning plate 18 is fixedly sleeved on the slide bar 9, and the positioning plate 18 is located below the connecting plate 17, the movable groove 19 is longitudinally penetrated and opened on the connecting plate 17, the mounting seat 20 is transversely slidably connected to the wall surface of the movable groove 19, the mounting rod 21 is longitudinally penetrated through the mounting seat 20, and the mounting rod 21 is slidably connected to the mounting seat 20, and the limit block 22 is fixedly installed on the top of the mounting rod 21;

[0073] The mounting frame 23 is fixedly mounted on the bottom end of the mounting rod 21, and the rubber sealing strips 24 arranged at equal intervals are fixedly mounted on the outer side surface of the mounting frame 23.

[0074] Working principle: During use, when it rains, rainwater will fall into the water tank 6 and be collected. After the water is collected, the water tank 6 will move downward to shrink the telescopic rod 5 and the spring 7 will be compressed.

[0075] When the water tank 6 moves downward, it will drive the slide bar 9 to move downward synchronously. When the slide bar 9 moves, it will drive the driving rack 10 to move downward synchronously, so that the driving gear 12 meshing with the driving rack 10 drives the twisted rod 11 to rotate, so that the slider 13 threadedly connected with the twisted rod 11 moves forward. The movement of the slider 13 will drive the connecting rod 14, the installation frame 15 and the rubber sealing ring 16 to move forward synchronously, so that the rubber sealing ring 16 will be close to the door gap between the cabinet door 2 and the cabinet body 1, and the door gap will be closed, thereby preventing rainwater from entering the cabinet body 1 through the door gap;

[0076] When the slide bar 9 moves downward, the positioning plate 18 moves downward, so that the connecting plate 17 on the top of the positioning plate 18 will move downward. When the connecting plate 17 moves downward, the mounting seat 20 and the mounting rod 21 move downward synchronously until the bottom surface of the mounting frame 23 moving downward with the mounting rod 21 hits the inner bottom surface of the cabinet 1. The slide bar 9 can continuously drive the positioning plate 18 and the push block 26 to move downward. At this time, the mounting frame 23 will remain stable in the current position. At the same time, the rubber sealing strip 24 is located on the inner side of the ventilation slot 3. At this time, when the slide bar 9 moves downward, the mounting frame 23 will be stable in the current position. At the same time, the rubber sealing strip 24 is located on the inner side of the ventilation slot 3. As the rod 9 and the push block 26 continue to move downward, the push block 26 will push the contact block 27 to move outward, so that the mounting frame 23 and the rubber sealing strip 24 move outward synchronously. At the same time, the mounting frame 23 drives the mounting seat 20 to move outward through the mounting rod 21 to stretch the tension spring 25 until the rubber sealing strip 24 moving outward is close to the ventilation slot 3, sealing the ventilation slot 3 to prevent rainwater from entering the cabinet 1 through the ventilation slot 3. At the same time, the slide bar 9 contacts the inner bottom surface of the cabinet 1, so that the slide bar 9 supports the water tank 6.

[0077] After the rainy weather, the water in the water tank 6 can be drained through the drain pipe 8, or evaporated naturally. When the water in the water tank 6 is reduced, the spring 7 is released to push the water tank 6 to return to its original position, so that the slide bar 9 is driven to return to its original position upward, so that the driving rack 10 returns to its original position upward, so that the driving gear 12 drives the twisted rod 11 to rotate in the opposite direction, so that the slide bar 13 drives the connecting rod 14, the installation frame 15 and the rubber sealing ring 16 to move backward, thereby releasing the seal of the door gap;

[0078] When the slide bar 9 is reset upward and the push block 26 is moved upward, the mounting seat 20 drives the mounting rod 21, the mounting frame 23 and the rubber sealing strip 24 to reset inward through the pulling action of the tension spring 25, so that the sealing of the ventilation slot 3 is released. After the positioning plate 18 that resets upward with the slide bar 9 hits the bottom surface of the connecting plate 17, it drives the connecting plate 17 to reset upward, so that the mounting seat 20 moves upward and drives the mounting rod 21, the mounting frame 23 and the rubber sealing strip 24 to reset upward under the action of the limit block 22, so that the rubber sealing strip 24 is misaligned with the ventilation slot 3, and the ventilation effect of the ventilation slot 3 can be guaranteed at this time.

[0079] Through the above method, the cabinet 1 can be sealed in rainy weather to prevent rainwater from entering, thereby ensuring the effective use of electrical components in the cabinet 1 and increasing their service life. Contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
