[0018] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0019] Please refer to Figures 1-7 , as shown in the figure, a power distribution cabinet that is convenient for maintenance provided in this embodiment, as Figures 1-2 shown, includes a main body 1 of the power distribution cabinet. A lifting mechanism 2 is fixedly connected to the bottom of the main body 1 of the power distribution cabinet; a heat dissipation and dehumidification mechanism 3 is fixedly installed inside the main body 1 of the power distribution cabinet; referring to Figure 2 and Figures 4-5 shown, the main body 1 of the power distribution cabinet includes a main housing 101. A hollow partition board 102 is fixedly installed inside the main housing 101. The lifting mechanism 2 includes a hollow supporting base 21 arranged at the bottom of the main housing 101. The heat dissipation and dehumidification mechanism 3 includes a hollow cover cylinder 31 fixedly installed at the bottom of the main housing 101 and extending into the inside of the hollow supporting base 21. An upper cover cylinder 32 is fixedly installed in the inner cavity of the hollow cover cylinder 31. A lower hollow cover cylinder 33 communicating with the hollow cover cylinder 31 is connected to the bottom of the upper cover cylinder 32. Among them, both the upper cover cylinder 32 and the lower hollow cover cylinder 33 are conical in shape. When the upper cover cylinder 32 and the lower hollow cover cylinder 33 are spliced together, they are in a funnel shape. Under normal conditions, a part of desiccant can also be filled in the cavity formed between the hollow cover cylinder 31 and the lower hollow cover cylinder 33.

[0020] Combined with Figures 6-7As shown, a hollow limiting cover 34 is fixedly installed at the top of the upper cover cylinder 32. The hollow limiting cover 34 is provided with air circulation holes. Air can enter the inner cavity of the main housing 101 through the side and top of the hollow cover cylinder 31. A heat dissipation fan assembly 35 is rotatably installed at the top of the hollow limiting cover 34. A reciprocating threaded screw rod 36 fixedly connected to the heat dissipation fan assembly 35 is rotatably installed at the bottom of the hollow limiting cover 34. The bottom of the reciprocating threaded screw rod 36 is fixedly installed with a connecting rotating rod 37 rotatably connected to the lower hollow cover cylinder 33. And one end of the connecting rotating rod 37 extending out of the bottom of the lower hollow cover cylinder 33 is fixedly connected with a motor 38 for driving it to rotate.

[0021] It can be understood that when heat dissipation and ventilation of the power distribution cabinet are required, the user can start the motor 38. The motor 38 can drive the connecting rotating rod 37 and the reciprocating threaded screw rod 36 to rotate synchronously, and then drive the heat dissipation fan assembly 35 to start ventilation operation, increasing the air circulation speed in the inner cavity of the main housing 101, so as to accelerate the speed of the outside air flowing into the inner cavity of the main housing 101 through the inner cavity of the hollow cover cylinder 31, facilitating the reduction of the temperature inside the power distribution cabinet. At the same time, when the gas circulates, it can preferentially pass through the desiccant stored in the hollow cover cylinder 31 to dry the humid gas in the air, reducing the risk of electrochemical corrosion of insulating materials and metal components, improving the service life of the power distribution cabinet, and greatly reducing the maintenance cost.

[0022] It should be noted that the desiccant in the lower hollow cover cylinder 33 is usually stored in a fixed stacked manner. The air gap between the desiccants is fixed, and the desiccants are very closely attached to each other, which will not only cause poor air circulation, but also cause some desiccants to not be able to fully contact the moisture in the air, thus affecting its dehumidification effect. Therefore, maintaining an appropriate air gap can ensure the free circulation of air and improve the dehumidification effect.

[0023] Furthermore, referring to Figure 7 As shown, a plurality of multi-directional stirring rods 311 are fixedly installed on the outer wall of the connecting rotating rod 37. The plurality of multi-directional stirring rods 311 are all arranged in an annular and equidistant state around the outer circumferential surface of the connecting rotating rod 37. A push plate 310 is connected to the outer wall of the reciprocating threaded screw rod 36 in a spiral transmission manner. The top of the push plate 310 is arranged in a slope shape. During the upward movement, a gap is gradually generated between the push plate 310 and the inner wall of the upper cover cylinder 32. The slope shape is convenient for the desiccant to fall into the inner cavity of the lower hollow cover cylinder 33. The outer circumferential diameter length of the push plate 310 is the same as the inner circumferential diameter length of the bottom of the upper cover cylinder 32. The bottom of the reciprocating threaded screw rod 36 corresponds to the bottom position of the upper cover cylinder 32. When the push plate 310 is at the bottom of the reciprocating threaded screw rod 36, the push plate 310 is also at the bottom of the upper cover cylinder 32.

[0024] It can be understood that when the motor 38 is started, it can drive the connecting rotating rod 37, the reciprocating threaded screw rod 36 and the heat dissipation fan assembly 35 to rotate synchronously. During the rotation of the connecting rotating rod 37, it will drive a plurality of multi-directional stirring rods 311 to rotate in the inner cavity of the lower hollow cover cylinder 33, agitating the desiccant stacked in the lower hollow cover cylinder 33, not only making the air gap between the desiccants loose, but also changing the position of the desiccants, so that the desiccants can fully contact the air;

[0025] Meanwhile, during the rotation of the reciprocating threaded screw rod 36, it will drive the push plate 310 to move up and down reciprocally on the outer wall of the reciprocating threaded screw rod 36. When the push plate 310 moves to the bottom of the upper cover cylinder 32, it will extrude the overly loose desiccant in the lower hollow cover cylinder 33;

[0026] Under the combined action of the multi-directional stirring rod 311 and the push plate 310, the desiccant in the lower hollow cover cylinder 33 will be intermittently agitated and extruded, making the position of the desiccant and the air gap between the desiccants in a dynamically changing state. During this process, the heat dissipation fan assembly 35 can not only more smoothly guide more external air into the main housing 101, but also the air flow can more fully contact the desiccant, achieving efficient dehumidification while dissipating heat.

[0027] Furthermore, at the same time, a directional dust scraping plate 39 fixedly connected to the connecting rotating rod 37 is slidably installed on the outer wall of the hollow cover cylinder 31. An annular through groove is opened at the top of the hollow supporting base 21, and the inner circumferential diameter length of the annular through groove is consistent with the sum of the outer circumferential diameter length of the hollow cover cylinder 31 and the thickness of the directional dust scraping plate 39. The purpose of such a setting is to enable the directional dust scraping plate 39 to rotate and move on the outer wall of the hollow cover cylinder 31 and the inner wall of the annular through groove of the hollow supporting base 21 as the connecting rotating rod 37 rotates, so as to scrape off the dust adhering to the outer wall of the hollow cover cylinder 31, avoiding the problem that bacteria multiply after impurities adhere and are invaded by moisture, thus affecting the ventilation effect.

[0028] A lifting mechanism 2 is provided at the bottom of the power distribution cabinet main body 1. The lifting mechanism 2 includes a hollow supporting base 21 provided below the power distribution cabinet main body 1. Two limiting sliding grooves 23 are opened at the top of the hollow supporting base 21, and a positioning type supporting bracket 24 fixedly connected to the main housing 101 is installed in the limiting sliding grooves 23.

[0029] Furthermore, referring to Figure 2 and Figures 4-5As shown, a balance backing plate 22 is fixedly installed on the outer wall of the hollow supporting base 21. Two limiting sliding grooves 23 are formed at the top of the hollow supporting base 21. A positioning support bracket 24 fixedly connected to the main housing 101 is slidably installed in the inner cavity of each of the two limiting sliding grooves 23. And in the normal state, the two positioning support brackets 24 are symmetrically arranged with respect to the vertical center line of the hollow supporting base 21. The purpose of such a setting is to enable the two positioning support brackets 24 to center and limit the main housing 101 on the top of the hollow supporting base 21, so as to maintain the overall installation stability and convenience of the power distribution cabinet body 1.

[0030] One side of the positioning support bracket 24 is connected with a first threaded support rod 25. Two protective baffle plates 28 are installed on the top of the hollow supporting base 21. The bottom of the first threaded support rod 25 is connected with a guiding sliding support plate 26. A second threaded support rod 27 is connected inside the guiding sliding support plate 26. The second threaded support rod 27 is rotatably connected to the hollow supporting base 21.

[0031] Furthermore, at the same time, a first threaded support rod 25 is in screw drive connection with one side of each of the two positioning support brackets 24. Two protective baffle plates 28 are fixedly installed on the top of the hollow supporting base 21. One end of the first threaded support rod 25 that penetrates through the limiting sliding groove 23 and extends into the inner cavity of the hollow supporting base 21 is rotatably connected with a guiding sliding support plate 26. A second threaded support rod 27 rotatably connected to the hollow supporting base 21 is in screw drive connection with the inner cavity of the guiding sliding support plate 26. The purpose of such a setting is that when the second threaded support rod 27 is rotated, the guiding sliding support plate 26 can drive the positioning support bracket 24 and the first threaded support rod 25 as a whole to horizontally displace left and right on the top of the hollow supporting base 21, so as to be applicable to limit and clamp the main housing 101 of different sizes. When the first threaded support rod 25 is rotated, the positioning support bracket 24 can drive the main housing 101 as a whole to move up and down on its outer wall, so as to adjust the overall installation height of the power distribution cabinet body 1.

[0032] One end of the second threaded support rod 27 is fixedly connected with a first connecting gear rod 29. An electric rotating rod 210 is installed in the hollow supporting base 21. Second connecting gear rods 211 are fixedly installed at both ends of the electric rotating rod 210. The second connecting gear rods 211 are in transmission connection with the electric rotating rod 210 through a transmission belt 212.

[0033] Furthermore, combined with Figure 5As shown, one end of each of the two second threaded support rods 27 is fixedly connected to a first connecting gear rod 29. An electric rotating rod 210 is fixedly installed inside the hollow support base 21. Second connecting gear rods 211 are fixedly installed at both ends of the electric rotating rod 210. A transmission belt 212 is engaged with the outer walls of both the second connecting gear rod 211 and the electric rotating rod 210. During actual use, by driving the electric rotating rod 210 to rotate, the two second connecting gear rods 211 can be made to rotate synchronously. Then, in combination with the settings of the transmission belt 212 and the first connecting gear rod 29, the two second threaded support rods 27 can be made to rotate synchronously, and then the two positioning brackets 24 can be driven to translate synchronously, so as to clamp and limit both sides of the main housing 101 and limit and fix the main housing 101.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
