Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a heat dissipation power distribution cabinet. Background Art

[0002] A heat dissipation distribution cabinet refers to a distribution cabinet with good heat dissipation performance. Since a large number of electrical equipment and components are usually installed inside the distribution cabinet, these equipment will generate heat when working. If it cannot be dissipated in time, it may cause the equipment to overheat, thereby affecting its normal operation or even causing failures. Therefore, the design and construction of heat dissipation distribution cabinets are very important. Existing heat dissipation distribution cabinets usually have good ventilation design: the distribution cabinet is usually designed with ventilation holes or cooling fans to ensure air circulation to take away the heat. In addition, some distribution cabinets also use forced air cooling or natural air cooling to improve the heat dissipation effect and high-quality heat dissipation materials: the cabinet body of the distribution cabinet is usually made of materials with good thermal conductivity and high temperature resistance, such as aluminum alloy, stainless steel, etc. These materials can effectively conduct the heat generated by the equipment to avoid equipment overheating and other characteristics;

By setting a moisture-proof device, personnel can fix the moisture-proof plate to the rectangular rod through bolts, so that the rectangular rod can be moved to insert the moisture-proof plate into the concave plate for plugging and fixing. The moisture-proof plate is located at the bottom of the cabinet to absorb the generated water droplets, reducing the situation where water accumulates at the bottom of the cabinet and affects the use of the internal circuit switch, and improving the moisture-proof property of the cabinet, thereby solving the problem that the circuit switch may gradually heat up inside the cabinet during use and have a temperature difference with the outside world, resulting in more water droplets on the inner wall of the cabinet, causing water accumulation at the bottom and affecting the use of the circuit switch.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The power distribution cabinet 1 (model SYEA), humidity sensor 6 (model CJ-TH200C) and stepper motor 8 (model 573S09) mentioned in the utility model can be purchased from the market or obtained through private customization.

[0023] See also Figures 1 to 3 The utility model provides an embodiment: a heat dissipation distribution cabinet, comprising a distribution cabinet 1, wherein a mounting groove 2 is provided inside the distribution cabinet 1, a placement groove 3 is provided at the middle position of the inner wall at the lower end of the mounting groove 2, and a moisture-proof plate 4 is placed inside the placement groove 3;

[0024] A sealing and drying mechanism is provided on one side of the moisture-proof plate 4, and the sealing and drying mechanism includes two sealing plates 11, two square grooves 13 and two flipping mechanisms. The two sealing plates 11 are respectively located on both sides above the moisture-proof plate 4, and the bottom ends of the sealing plates 11 are connected to the inner wall of the mounting groove 2 through a rotating shaft. The two square grooves 13 are respectively located in the middle position of the lower end surfaces of the two sealing plates 11, and a plurality of drying lamps 14 are fixedly installed inside the two square grooves 13. The sealing plate 11 can be driven to rotate with the rotating shaft connection at the bottom end as the center through the flipping mechanism.

[0025] The flipping mechanism includes a stepper motor 8, the output shaft of the stepper motor 8 is connected to a threaded rod 9 through a coupling, and the lower end surface of the threaded rod 9 is connected to the distribution cabinet 1 through a roller bearing; when the moisture-proof board 4 needs to be dried, the stepper motor 8 is started, and the stepper motor 8 can drive the threaded rod 9 connected thereto to rotate.

[0026] An internal threaded sleeve 10 is sleeved on the upper side of the outer surface of the threaded rod 9, and the internal thread of the internal threaded sleeve 10 matches the external thread of the threaded rod 9. The surface of the internal threaded sleeve 10 facing the sealing plate 11 is connected to a rotating shaft connecting rod 12 through a rotating shaft, and the surface of the rotating shaft connecting rod 12 facing the sealing plate 11 is connected to the sealing plate 11 through a rotating shaft; because the internal threaded sleeve 10 sleeved on the outer surface of the threaded rod 9 is connected to the sealing plate 11 through the rotating shaft connecting rod 12, the internal threaded sleeve 10 itself cannot rotate. When the threaded rod 9 rotates, the threaded sleeve 10 is connected to the sealing plate 11 but is threadedly connected to the sealing plate 11. The internal threaded sleeve 10, which cannot rotate by itself, will move up and down on the outer surface of the threaded rod 9. At this time, the internal threaded sleeve 10 moves downward. As the internal threaded sleeve 10 descends, the sealing plate 11 will be pushed to rotate around the shaft connection point through the shaft connecting rod 12. When the two sealing plates 11 are driven by the internal threaded sleeve 10 moving downward to rotate ninety degrees, the upper end surfaces of the two internal threaded sleeves 10 will fit each other, thereby sealing the moisture-proof plate 4. After the moisture-proof plate 4 is sealed, the moisture-proof plate 4 can be dried by the drying lamp 14.

[0030] The above technical solution can prevent the moisture-proof board 4 from being in a state of absorption saturation for a long time, thereby extending its service life. In addition, by regularly drying the moisture-proof board 4, the possibility of the moisture-proof board 4 becoming moldy or deteriorating due to long-term moisture can be reduced. Automatically drying the moisture-proof board 4 every evening can ensure that the distribution cabinet 1 is not affected by external moisture at night or in humid conditions, which helps to maintain a dry environment inside the distribution cabinet. Regularly drying the moisture-proof board 4 can reduce the need for manual intervention. It can automatically perform these operations every evening, making the maintenance of the moisture-proof board 4 easier and more efficient.
