[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1-6 , the utility model provides an embodiment: a moisture-proof low-voltage power distribution device, including a power distribution device body 1, both sides of the power distribution device body 1 are provided with ventilating holes 2, the ventilating holes 2 play a role in ventilating and dissipating heat inside the power distribution device body 1, one side of the power distribution device body 1 is connected with a circulation pipe 3, the circulation pipe 3 is arranged below the ventilating holes 2, a dehumidification box 4 is sleeved on the circulation pipe 3, the dehumidification box 4 is connected with the circulation pipe 3, a circulation mechanism 5 is arranged inside one end of the circulation pipe 3, the circulation mechanism 5 is used to circulate the air inside the power distribution device body 1 to the inside of the dehumidification box 4, a refrigeration pump 6 is fixedly connected above the dehumidification box 4, a heat exchange pipe 7 is fixedly connected inside the dehumidification box 4, the refrigeration pump 6 is used to refrigerate the heat exchange pipe 7, and both ends of the heat exchange pipe 7 pass through the inner wall of the dehumidification box 4 and are connected with the refrigeration pump 6;
[0025] The circulation mechanism 5 includes a fixed bracket 51, a motor 52, a rotating rod 53 and a circulation fan blade 54. The fixed bracket 51 is fixedly connected to the inner wall of the circulation pipe 3, the motor 52 is fixedly connected to the fixed bracket 51, one end of the rotating rod 53 is fixedly connected to the output end of the fixed bracket 51, and the circulation fan blade 54 is sleeved on the rotating rod 53 and fixedly connected thereto.
[0026] Through the above technical scheme, by setting up a circulation mechanism 5 and starting the motor 52 to drive the rotating rod 53 to rotate, the rotating rod 53 can drive the circulation fan blades 54 to rotate, so that the humid air inside the distribution device body 1 can be drawn into the dehumidification box 4. Under the action of the refrigeration pump 6 and the heat exchange tube 7, the humid air can be dehumidified and dried.
[0027] Specifically, a heating network 9 is provided inside the other end of the circulation pipe 3 and is fixedly connected to the inner wall of the circulation pipe 3 .
[0028] Through the above technical solution, by setting up the heating network 9, the cooling air passing through the dehumidification box 4 can be heated to a certain extent to prevent the cold air from directly entering the interior of the distribution device body 1, causing the internal equipment of the distribution device body 1 to be unable to use normally.
[0029] Specifically, a plurality of cooling substrates 8 are disposed inside the dehumidification box 4 , and the cooling substrates 8 are all fixedly connected to the heat exchange tubes 7 .
[0030] Through the above technical solution, by providing the cooling substrate 8, the contact area between the humid air and the cooling substrate 8 can be increased, thereby increasing the dehumidification effect of the refrigeration pump 6 and the heat exchange tube 7.
[0031] Specifically, the interior of the dehumidification box 4 is fixedly connected with a water storage box 10, which is arranged below the heat exchange tube 7. One side of the water storage box 10 is connected to a drain pipe 11, and the other end of the drain pipe 11 passes through the dehumidification box 4 and extends to the outside thereof.
[0032] Through the above technical solution, by setting up the water storage box 10 and the drain pipe 11, when too much water droplets condense on the cooling substrate 8, they will drip into the inside of the water storage box 10, and the water inside the water storage box 10 can be discharged through the drain pipe 11.
[0033] Specifically, a humidity and temperature detector 13 is fixedly connected to one side of the power distribution device body 1 , and the humidity and temperature detector 13 is arranged on one side of the vent 2 . The test end of the humidity and temperature detector 13 penetrates through the power distribution device body 1 and extends into the interior thereof.
[0034] Through the above technical scheme, by setting up a humidity and temperature detector 13, the humidity and temperature of the environment inside the distribution device body 1 can be effectively detected through the humidity and temperature detector 13, so that the staff can manage the humidity and temperature detector 13 to open or close the circulation mechanism 5, the refrigeration pump 6 and the heating network 9.
[0035] Specifically, both ends of the circulation pipe 3 are fixedly connected with the protection net 14 , and the other end of the drainage pipe 11 is fixedly connected with the barrier net 12 .
[0036] Through the above technical scheme, by setting up the protective net 14, it is possible to prevent foreign objects from entering the interior of the circulation pipe 3 and the dehumidification box 4 and causing damage to the equipment inside them. By setting up the barrier net 12, it is possible to prevent foreign objects from clogging the drain pipe 11, making it impossible for the water in the water storage box 10 to be discharged and overflowing into the interior of the distribution device body 1, causing electric shock to the equipment inside the distribution device body 1, thereby affecting the safe use of the distribution device body 1.
[0037] Working principle: When in use, firstly, the humidity and temperature of the environment inside the power distribution device body 1 are detected by the humidity and temperature detector 13. Then, when the humidity inside the power distribution device body 1 is high, the rotating rod 53 can be driven to rotate by starting the motor 52, so that the rotating rod 53 drives the circulating fan blades 54 to rotate, and the humid air inside the power distribution device body 1 can be drawn into the dehumidification box 4. Then, the heat exchange tube 7 is cooled by starting the refrigeration pump 6, so as to reduce the temperature of the cooling substrate 8. When the humid air passes through the cooling substrate 8, the moisture in the air will condense into water droplets when it is cooled and adhere to the cooling substrate 8. At the same time, under the action of the circulation mechanism 5, the dry cold air can be returned to the inside of the power distribution device body 1 again, so as to achieve the purpose of dehumidification. It can dehumidify and prevent moisture inside the power distribution device body 1. When too much water droplets condense on the cooling substrate 8, they will drip into the water storage box 10. The water inside the water storage box 10 can be discharged through the drain pipe 11. At the same time, by observing the humidity and temperature detector 13, when it is shown that the temperature inside the power distribution device body 1 is too low, the heating network 9 can be turned on to heat the cooling air under the action of the refrigeration pump 6 and the heat exchange tube 7 to prevent the cold air from directly entering the inside of the power distribution device body 1, causing the internal equipment of the power distribution device body 1 to be unable to be used normally. When the humidity and temperature detector 13 shows that the temperature inside the power distribution device body 1 is too high, the heating network 9 can be turned off to dissipate heat inside the power distribution device body 1.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
