Abstract
Description
Technical Field
[0001] The utility model relates to the improvement of a power distribution cabinet, in particular to a waterproof heat dissipation power distribution cabinet. Background Art
[0002] A distribution cabinet is one of the common power facilities and is usually used to install power facilities. Since distribution cabinets are usually arranged in the open air, they have requirements for waterproof performance. The power components of the distribution cabinet generate a lot of heat, so the distribution cabinet needs to have good heat dissipation performance. A distribution cabinet in the related art uses a rain shelter, a pad, etc. to waterproof, and at the same time, heat dissipation holes are opened on the cabinet body to dissipate heat. For example, an invention patent application with publication number CN111224325A published by the State Intellectual Property Office on June 2, 2020 discloses a waterproof and heat-dissipating distribution cabinet. The distance between the distribution cabinet and the ground can effectively prevent water from entering the distribution cabinet from below. The distribution cabinet has high space utilization, energy saving and environmental protection, good cooling effect, and ensures the normal operation of the distribution cabinet. The shock-absorbing spring is provided to make the distribution cabinet more stable when placed. The arc-shaped rainproof roof provided above can prevent water from entering the distribution cabinet from above. The heat dissipation strips provided make the distribution cabinet have good heat dissipation and good air permeability, easy installation and maintenance, and increase the service life of the distribution cabinet.
[0003] During actual use, it was found that a small amount of moisture would still penetrate into the distribution cabinet. Through observation, it was found that although there was a rain shelter on the top of the cabinet, rainy and snowy weather is usually accompanied by strong winds. A small amount of moisture would still enter the rain shelter with the help of the wind, and the waterproof effect was not good. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a waterproof heat dissipation distribution cabinet.
[0005] The utility model adopts the following technical solution: a waterproof heat dissipation distribution cabinet, comprising a cabinet body, a heat dissipation component and a water-proof component are arranged in the cabinet body, a plurality of heat dissipation waist holes are opened on the cabinet body, the water-proof component is arranged on the side wall of the heat dissipation waist hole, and the heat dissipation component is arranged at the bottom of the cabinet body;
[0006] The water-proof component is used to close the heat dissipation waist hole. A circulation hole is provided at the bottom of the cabinet. The heat dissipation component is provided at the circulation hole. The heat dissipation component is activated when the heat dissipation waist hole is closed.
[0007] The water-proof component includes a sealing part and an air-sealing part. The sealing part is arranged on the heat dissipation waist hole for closing the heat dissipation waist hole. The air-sealing part is arranged on the heat dissipation waist hole for blowing air into the gap between the sealing part and the heat dissipation waist hole.
[0008] The sealing portion includes a sealing plate, and a sealing plate is rotatably connected to the side wall of each heat dissipation waist hole, and the sealing plate is rotatably closed or opened.
[0009] The air sealing portion includes an air nozzle arranged on the side wall of the heat dissipation waist hole. When the sealing plate closes the heat dissipation waist hole, the air nozzle sprays air toward the gap between the sealing plate and the heat dissipation waist hole.
[0010] The heat dissipation component includes a lifting portion and a heat dissipation portion. The lifting portion is arranged at the bottom of the cabinet body, and the heat dissipation portion is arranged on the cabinet body and placed at the circulation hole.
[0011] The lifting part includes a lifting seat, which is arranged at the bottom of the cabinet and reciprocates and extends along the height direction of the cabinet. A receiving hole is provided at the bottom of the cabinet, and the lifting seat is inserted into the receiving hole. A linear drive device is provided in the receiving hole to drive the lifting seat to extend and retract.
[0012] The heat dissipation part includes a heat dissipation fan, which is arranged at the bottom of the cabinet and covers the circulation hole.
[0013] Compared to the prior art, the present invention dissipates heat through both the heat dissipation holes and the circulation holes on sunny days. However, when precipitation occurs, the heat dissipation holes are sealed by a sealing member. After sealing, the air seal blows air outward through the gap in the sealing member. Rainwater passing through the heat dissipation holes is blocked by the sealing member, and the gap between the sealing member and the heat dissipation holes also has an outward-blowing airflow. Even if a small amount of rainwater is trapped in the gap, it is blown away by the high-pressure airflow and prevented from entering the cabinet. At this time, the lifting seat extends from the receiving hole, lifting the entire cabinet body, lifting it off the ground and relying solely on the lifting seat for contact with the ground. This creates a gap between the bottom of the cabinet body and the ground, preventing any accumulated water from seeping into the cabinet body. Meanwhile, the heat dissipation member remains in operation, promoting internal and external air circulation, achieving heat dissipation. During rainy days, the circulation hole in the cabinet body, which connects to the outside world, is located at the bottom of the cabinet body, and the cabinet body is off the ground. This makes it difficult for precipitation to enter the cabinet body, improving the waterproofing effect. Furthermore, the circulation hole can continue to circulate with external air on rainy days, maintaining the original heat dissipation conditions. It has good waterproof effect and excellent heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0017] Reference Figure 1 A waterproof heat dissipation distribution cabinet includes a cabinet body 1, a heat dissipation component 3 and a water-blocking component 2 are provided in the cabinet body 1, a plurality of heat dissipation waist holes 11 are provided on the cabinet body 1, and a water retaining edge 13 can be fixed on the outer wall of the cabinet body 1. A water retaining edge 13 is fixed above each heat dissipation waist hole 11, and the end surface of the water retaining edge 13 faces downward to form a water guide surface, thereby reducing the possibility of water entering the cabinet body 1 through the heat dissipation waist hole 11. The water-blocking component 2 is provided on the side wall of the heat dissipation waist hole 11, and the heat dissipation component 3 is provided at the bottom of the cabinet body 1. The water component is used to close the heat dissipation waist hole 11, and a circulation hole 12 is provided at the bottom of the cabinet body 1. The heat dissipation component 3 is provided at the circulation hole 12. When the heat dissipation waist hole 11 is closed, the heat dissipation component 3 is activated. The heat dissipation waist hole 11 is on the side wall of the cabinet body 1, so that the heat dissipation waist hole 11 can be connected to the external environment for heat dissipation. At the same time, the circulation hole 12 at the bottom also plays a role in heat dissipation. On rainy days, the heat dissipation waist holes 11 on the side of the cabinet 1 are closed, but the circulation holes 12 at the bottom are still retained to exchange heat with the outside, thereby reducing heat accumulation. At the same time, since the heat dissipation waist holes 11 on the side have been closed, rainwater cannot enter the cabinet 1, and the waterproof performance is better without affecting the heat dissipation.
[0018] The water-proof assembly 2 includes a sealing portion 21 and an air-sealing portion 22. The sealing portion 21 is provided on the heat dissipation waist hole 11 to seal the heat dissipation waist hole 11, and the air-sealing portion 22 is provided on the heat dissipation waist hole 11 to blow air into the gap between the sealing portion 21 and the heat dissipation waist hole 11. The sealing portion 21 includes a sealing plate 211. A sealing plate 211 is rotatably connected to the side wall of each heat dissipation waist hole 11, and the sealing plate 211 rotates to close or open the heat dissipation waist hole 11. The air-sealing portion 222 includes an air nozzle 221 provided on the side wall of the heat dissipation waist hole 11. When the sealing plate 211 seals the heat dissipation waist hole 11, the air nozzle 221 sprays air into the gap between the sealing plate 211 and the heat dissipation waist hole 11. On sunny days, the sealing plate 211 is rotated so that the heat dissipation waist hole 11 is in an open state to exchange air with the outside world. At this time, the circulation hole 12 at the bottom can also realize the heat dissipation function. In the initial state, there is a gap between the circulation hole 12 and the ground to facilitate heat dissipation. On rainy days, the heat dissipation waist hole 11 can be closed by rotating the sealing plate 211. A rubber strip can be fixed to the edge of the sealing plate 211. During rotation, the rubber strip contacts the air nozzle 221 and can pass over the air nozzle 221 with only a slight force. The rubber strip not only forms a stable seal but also allows it to easily pass over the air nozzle 221 when it contacts the air nozzle 221 during rotation without damaging the air nozzle 221. This maintains the normal use of the air nozzle 221 without affecting the rotation of the sealing plate 211. After sealing, the heat dissipation component 3 can dissipate heat separately through the circulation hole 12 at the bottom. At this time, the circulation hole 12 remains open and can dissipate heat. Since the circulation hole 12 is located at the bottom of the cabinet 1, it is not easy for water to enter.
[0019] The heat dissipation assembly 3 includes a lifting portion 31 and a heat dissipation portion 32. The lifting portion 31 is provided at the bottom of the cabinet 1, and the heat dissipation portion 32 is provided on the cabinet 1 and placed at the circulation hole 12. The lifting portion 31 includes a lifting seat 311. The lifting seat 311 is provided at the bottom of the cabinet 1 and reciprocates and retracts along the height direction of the cabinet 1. A receiving hole is provided at the bottom of the cabinet 1, and the lifting seat 311 is inserted into the receiving hole. A linear drive device 312 is provided in the receiving hole to drive the lifting seat 311 to retract. The heat dissipation portion 32 includes a heat dissipation fan 321. The heat dissipation fan 321 is provided at the bottom of the cabinet 1 and covers the circulation hole 12. The linear drive device 312 can be activated when there is water on the ground.
[0020] Compared with the prior art, the present invention dissipates heat through the heat dissipation waist hole 11 and the circulation hole 12 together on sunny days. However, once precipitation occurs, the heat dissipation waist hole 11 is sealed by the sealing part 21. After sealing, the air sealing part 22 blows air into the gap of the sealing part 21, and the airflow is outward. When rainwater passes through the heat dissipation waist hole 11, it is blocked by the sealing part 21. The gap between the sealing part 21 and the heat dissipation waist hole 11 also has an airflow blowing outward. Even if a small amount of rainwater is retained in the gap, it can be blown away by the high-pressure airflow and will not enter the cabinet 1. At this time, the lifting seat 311 extends from the receiving hole, lifting the entire cabinet 1, so that the cabinet 1 is off the ground and only relies on the lifting seat 311 to contact the ground. That is, there is a gap between the bottom of the cabinet 1 and the ground. Even if there is water on the ground, it will not penetrate into the cabinet 1. At the same time, the heat dissipation part 32 is still in working condition, promoting the circulation of air inside the cabinet 1 and the outside air, thereby achieving the purpose of heat dissipation. On rainy days, the circulation hole 12 on the cabinet 1 that communicates with the outside world is at the bottom of the cabinet 1, and the cabinet 1 is off the ground. Precipitation is difficult to enter the cabinet 1, and the waterproof effect is better. At the same time, the circulation hole 12 can continue to circulate with the outside air on rainy days, maintaining the original heat dissipation.
[0021] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
