Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets, and more specifically, particularly relates to a moisture-proof switch cabinet. Background Technique

[0002] A switch cabinet is an electrical device. The external wires of the switch cabinet first enter the main control switch inside the cabinet, and then enter the sub-control switch. Each branch is set as required, such as meters, automatic controls, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switch cabinets, with high-voltage busbars, such as in power plants, etc. Some also have low-frequency load shedding to protect the main equipment. The main function of the switch cabinet is to open, control, and protect electrical equipment during the processes of power generation, transmission, distribution, and power conversion in the power system. The components inside the switch cabinet mainly include a circuit breaker, disconnector, load switch, operating mechanism, current transformer, voltage transformer, and various protection devices, etc.

[0003] The existing publication number CN219419959U discloses a moisture-proof switch cabinet. Although dry air is sprayed through a nozzle to increase the dryness inside the switch cabinet body, prevent moisture from generating inside the switch cabinet body, the air flow inside the switch cabinet body is increased by jetting air through the nozzle, the pressure difference balance inside the switch cabinet body is ensured through air holes, and the heat generated by the equipment inside the switch cabinet body is blown by jetting air through the nozzle, so that the heat inside the switch cabinet body is discharged through the air holes following the air inside the switch cabinet body, thereby improving the heat dissipation effect of the switch cabinet body.

[0004] Based on the above, the inventor found the following problems: However, this switch cabinet requires the wind force of a fan to blow up the cover plate at the air outlet. The switch cabinet is already large in volume, and the wind force is small when it is transmitted to the top of the cabinet body, and the blowing angle of the cover plate is also small, resulting in a reduction in heat dissipation efficiency. At the same time, this switch cabinet uses only wind force for internal cooling of the cabinet. In hot weather, the external temperature is high, and the temperature of the gas blown into the cabinet body will also be high, still affecting heat dissipation.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a moisture-proof switch cabinet is provided in order to achieve a more practical and valuable purpose. Summary of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a moisture-proof switch cabinet to solve the problem that the wind force is small when it is transmitted to the top of the cabinet body, and the blowing angle of the cover plate is also small, resulting in a reduction in heat dissipation efficiency.

[0007] The utility model provides a moisture-proof switch cabinet, which is achieved by the following specific technical means:

[0008] A moisture-proof switch cabinet, comprising a cabinet body. At the bottom of one side of the cabinet body, an air inlet is penetrated and opened. One side of the air inlet close to the inner wall of the cabinet body is fixed with a first air duct. At the top of one end of the first air duct close to the air inlet, a first connecting block is fixed. One side of the first connecting block is rotatably connected with a first baffle. One end of the first air duct far from the air inlet is fixed with a second air duct. A desiccant plate is detachably installed through the outer wall of the second air duct. A fan is fixedly penetrated through the middle of the outer wall of the second air duct. One side of the middle of the second air duct is fixed with a cooling box. A water guide pipe is fixedly penetrated through the cooling box. One side of the middle of the outer wall of the cooling box is fixed with a temperature sensor. The top of the second air duct is fixed with a wind guide plate. Ventilation holes are penetrated and opened at the top of the wind guide plate. An air outlet is penetrated and opened in the middle of the top of the cabinet body. An electromagnet is fixed in the middle of the air outlet. A second baffle is movably installed on the top of the outer wall of the cabinet body. A humidity sensor is fixed on the top of the outer wall of the cabinet body.

[0009] Further, four corners of the electromagnet on the top of the outer wall of the cabinet body are all fixed with second connecting blocks. There are two second baffles. One end of each of the two second baffles is rotatably connected with the four electromagnets respectively. Magnets are fixed at one end of each of the two second baffles opposite to each other, and the magnetism is the same as that of the electromagnet.

[0010] Further, the humidity sensor is electrically connected with the electromagnet, and the temperature sensor is electrically connected with the fan.

[0011] Further, there are multiple ventilation holes, and the multiple ventilation holes are arranged in an equidistant filling shape at the top of the wind guide plate.

[0012] Further, the fan, the cooling box and the desiccant plate are arranged in sequence from left to right as the desiccant plate, the fan and the cooling box.

[0013] Further, the vertical section of the water guide pipe is arranged in a W shape, and both ends of the water guide pipe are hermetically connected with an external water pump.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, the external air is detected through the humidity sensor. When the humidity of the external air is relatively high, the electromagnet is controlled to be powered off. When the electromagnet is powered off, the second baffle of the magnet adsorbs to the top of the cabinet body to keep the top of the cabinet body sealed and prevent rainwater from seeping in through the air outlet. When cooling, the electromagnet is powered on, so that the two second baffles can be tilted upward without the need of wind pushing, thereby achieving the effect of improving heat dissipation while having a sealing effect.

[0016] 2. In the present utility model, two connectors of the water guide pipe are connected to an external water pump and a water pipe. During use, the temperature sensor detects the temperature inside the cabinet. When the temperature is relatively high, it controls the fan to rotate. When the temperature is too high, it controls the external water pump to use the water guide pipe for water circulation. The W-shaped water guide pipe increases the contact area with the wind generated by the fan, and can quickly cool the wind that is about to blow out from the ventilation holes, so as to achieve a better heat dissipation effect even when the external temperature is relatively high.

[0026] As shown in Figure 1 to Figure 4 shown:

A desiccant plate 14 is detachably installed through the outer wall of the second air duct 5. A fan 6 is fixed through the middle of the outer wall of the second air duct 5. A cooling box 7 is fixed to one side in the middle of the second air duct 5. A water pipe 71 is fixed through the inside of the cooling box 7. A temperature sensor 8 is fixed to the middle of one side of the outer wall of the cooling box 7. A wind guide plate 9 is fixed to the top of the second air duct 5. Ventilation holes 10 are formed through the top of the wind guide plate 9. An air outlet 11 is formed through the middle of the top of the cabinet body 1. An electromagnet 12 is fixed to the middle of the air outlet 11. A second baffle 13 is movably installed on the top of the outer wall of the cabinet body 1. A humidity sensor 15 is fixed to the top of the outer wall of the cabinet body 1.

[0028] Wherein, second connecting blocks 131 are fixed to the four corners of the electromagnet 12 on the top of the outer wall of the cabinet body 1. There are two second baffles 13. The opposite ends of the two second baffles 13 are respectively rotatably connected to the four electromagnets 12. Magnets are fixed to the relative ends of the two second baffles 13 and have the same magnetism as the electromagnet 12. By energizing the electromagnet 12, the two second baffles 13 can be tilted upwards. A sealing ring is fixed to the bottom of the second baffle 13. When the electromagnet 12 is de-energized, the second baffle 13 with the magnet adsorbs to the top of the cabinet body 1 to keep the top of the cabinet body 1 sealed and prevent rainwater from seeping in from the air outlet 11.

[0029] Wherein, the humidity sensor 15 is electrically connected to the electromagnet 12, and the temperature sensor 8 is electrically connected to the fan 6. The external air is detected by the humidity sensor 15. When the humidity of the external air is relatively high, the electromagnet 12 will be controlled to be de-energized. The temperature inside the cabinet body 1 is detected by the temperature sensor 8. When the temperature is relatively high, the fan 6 will be controlled to rotate. When the temperature is too high, the external water pump will be controlled to use the water pipe 71 for water circulation.

[0030] Wherein, there are multiple ventilation holes 10, and the multiple ventilation holes 10 are arranged in an equidistant filling shape on the top of the wind guide plate 9. The fan 6 rotates to generate wind force, which is ejected upwards from the multiple ventilation holes 10 to cool and dissipate heat inside the cabinet body 1.

[0031] Wherein, the fan 6, the cooling box 7 and the desiccant plate 14 are arranged in sequence from left to right as the desiccant plate 14, the fan 6 and the cooling box 7. When the fan 6 rotates, the external air will first pass through the desiccant plate 14 for drying and filtering, and then pass through the cooling box 7 for cooling.

[0032] Among them, the vertical cross-section of the water conduit 71 is arranged in a W shape. Both ends of the water conduit 71 are hermetically connected to an external water pump. The W-shaped water conduit 71 increases the contact area with the wind generated by the fan 6, and can quickly cool the wind that is about to be blown out from the ventilation holes 10.

[0033] Specific usage method and function of this embodiment:

[0034] In this utility model, first connect the two joints of the water conduit 71 to an external water pump and a water pipe. During use, the temperature sensor 8 detects the temperature inside the cabinet 1. When the temperature is relatively high, it will control the fan 6 to rotate. When the temperature is too high, it will control the external water pump to use the water conduit 71 for water circulation. The wind is generated by the rotation of the fan 6 and is ejected upward from multiple ventilation holes 10 to perform air cooling and heat dissipation inside the cabinet 1. The external air will first pass through the desiccant plate 14 for drying and filtering, and then pass through the cooling box 7 for cooling. The W-shaped water conduit 71 increases the contact area with the wind generated by the fan 6, and can quickly cool the wind that is about to be blown out from the ventilation holes 10. At the same time, the electromagnet 12 is energized, so that the two second baffles 13 can tilt upward. The external air is detected by the humidity sensor 15. When the humidity of the external air is relatively high, it will control the electromagnet 12 to be powered off. When the electromagnet 12 is powered off, the second baffle 13 of the magnet adsorbs to the top of the cabinet 1. A sealing ring is fixed at the bottom of the second baffle 13 to maintain the sealing of the top of the cabinet 1 and prevent rainwater from seeping in from the air outlet 11.
