[0018] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0019] Please see Figures 1-7 As shown in the figure, this embodiment provides a power distribution cabinet that is easy to maintain. Figures 1-2 As shown, the system includes a main body 1 of a power distribution cabinet, with a lifting mechanism 2 fixedly connected to the bottom of the main body 1; a heat dissipation and dehumidification mechanism 3 is fixedly installed inside the main body 1; see reference. Figure 2 and Figures 4-5 As shown, the main body 1 of the distribution cabinet includes a main shell 101. A perforated partition 102 is fixedly installed inside the main shell 101. The lifting mechanism 2 includes a hollow support base 21 set at the bottom of the main shell 101. The heat dissipation and dehumidification mechanism 3 includes a perforated cover 31 fixedly installed at the bottom of the main shell 101 and extending into the hollow support base 21. An upper cover 32 is fixedly installed in the inner cavity of the perforated cover 31. The bottom of the upper cover 32 is connected to a lower perforated cover 33 that is connected to the perforated cover 31. The upper cover 32 and the lower perforated cover 33 are both conical. When the upper cover 32 and the lower perforated cover 33 are spliced ​​together, they are funnel-shaped. Under normal conditions, the cavity formed between the perforated cover 31 and the lower perforated cover 33 can also be filled with some desiccant.

[0020] Combination Figures 6-7As shown, the top of the upper hollow cover cylinder 32 is fixedly provided with a hollow limiting cover 34, which is provided with an air flow hole. Air can flow into the inner cavity of the main shell 101 through the side and top of the hollow cover cylinder 31. The top of the hollow limiting cover 34 is rotatably provided with a heat dissipation fan assembly 35. The bottom of the hollow limiting cover 34 is rotatably provided with a reciprocating screw rod 36 fixedly connected with the heat dissipation fan assembly 35. The bottom of the reciprocating screw rod 36 is fixedly provided with a connecting rotating rod 37 rotatably connected with the lower hollow cover cylinder 33. The 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 the connecting rotating rod 37 to rotate.

[0021] It can be understood that when it is necessary to dissipate heat and ventilate the power distribution cabinet, the user can start the motor 38. The motor 38 can drive the connecting rotating rod 37 and the reciprocating screw rod 36 to rotate synchronously, thereby driving the heat dissipation fan assembly 35 to start the ventilation work, increasing the air flow speed in the inner cavity of the main shell 101, thereby accelerating the speed of the external air flowing into the inner cavity of the main shell 101 through the inner cavity of the hollow cover cylinder 31, reducing the temperature inside the power distribution cabinet, and preferentially passing the desiccant stored in the hollow cover cylinder 31 to dry the humid gas in the air, thereby reducing the risk of electrochemical corrosion of the insulating material and metal components, prolonging 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 stacking manner. The air gap between the desiccants is fixed, and the desiccants are closely attached to each other. This not only causes poor air flow, but also causes some desiccants to be unable to fully contact the moisture in the air, thereby affecting the dehumidification effect. Therefore, maintaining an appropriate air gap can ensure that air can flow freely and improve the dehumidification effect.

[0023] Further, referring to Figure 7 As shown, the outer wall of the connecting rotating rod 37 is fixedly provided with a plurality of multidirectional stirring rods 311 arranged in a ring shape around the outer circumferential surface of the connecting rotating rod 37 in an equidistant state. The outer wall of the reciprocating screw rod 36 is spirally transmissionally connected with a push plate 310. The top of the push plate 310 is arranged in a slope shape. During the upward movement, the gap between the push plate 310 and the inner wall of the upper cover cylinder 32 is gradually increased. The slope shape facilitates 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 consistent with the inner circumferential diameter length of the bottom of the upper cover cylinder 32. The bottom of the reciprocating screw rod 36 corresponds to the position of the bottom of the upper cover cylinder 32. When the push plate 310 is at the bottom of the reciprocating 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, the connecting rotating rod 37, the reciprocating threaded rod 36 and the cooling fan assembly 35 can be driven to rotate synchronously. In the process of rotation of the connecting rotating rod 37, a plurality of multidirectional stirring rods 311 are driven to rotate in the inner cavity of the lower hollow cover cylinder 33, and the desiccant stacked in the lower hollow cover cylinder 33 is stirred, so that the air gap between the desiccants becomes loose, and the position of the desiccant is changed, so that the desiccant can fully contact the air.

[0025] At the same time, in the process of rotation of the reciprocating threaded rod 36, the push plate 310 is driven to move up and down reciprocally on the outer wall of the reciprocating threaded rod 36. When the push plate 310 moves to the bottom of the upper cover cylinder 32, the desiccant in the lower hollow cover cylinder 33 that is too loose is extruded.

[0026] Under the joint action of the multidirectional stirring rods 311 and the push plate 310, the desiccant in the lower hollow cover cylinder 33 is intermittently stirred and extruded, so that the position of the desiccant and the air gap between the desiccants are in a dynamic state. In this process, the cooling fan assembly 35 can more smoothly guide more external air into the main shell 101, and the airflow can more fully contact the desiccant, so that the desiccant is dehumidified and cooled.

[0027] Further, at the same time, the outer wall of the hollow cover cylinder 31 is slidably installed with a directional dust scraping plate 39 fixedly connected with the connecting rotating rod 37. The top of the hollow supporting base 21 is provided with an annular through groove, 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 arrangement is that the directional dust scraping plate 39 can 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 with the rotation of the connecting rotating rod 37, so as to scrape off the dust adhered to the outer wall of the hollow cover cylinder 31, avoid the problem that the bacteria grow after the impurities adhere and are invaded by moisture, and affect the ventilation effect.

[0028] The power distribution cabinet body 1 is provided with a lifting mechanism 2 at the bottom. The lifting mechanism 2 comprises a hollow supporting base 21 arranged below the power distribution cabinet body 1. The top of the hollow supporting base 21 is provided with two limiting sliding grooves 23, and the limiting sliding grooves 23 are installed with a positioning supporting frame 24 fixedly connected with the main shell 101.

[0029] Further, with reference to Figure 2 and Figures 4-5As shown, the outer wall of the hollow supporting base 21 is fixedly provided with a balance pad 22, and the top of the hollow supporting base 21 is provided with two limiting sliding grooves 23, the inner cavities of the two limiting sliding grooves 23 are both slidably provided with a positioning support frame 24 fixedly connected with the main shell 101, and the two positioning support frames 24 are symmetrically arranged about the vertical center line of the hollow supporting base 21 in the normal state. The purpose of such arrangement is to enable the two positioning support frames 24 to centrally position the main shell 101 on the top of the hollow supporting base 21, thereby maintaining the installation stability and convenience of the switchgear main body 1 as a whole.

[0030] The positioning support frame 24 is connected with a first threaded supporting rod 25 on one side, the hollow supporting base 21 is provided with two protective baffle plates 28 on the top, the first threaded supporting rod 25 is connected with a guide sliding support plate 26 at the bottom, the guide sliding support plate 26 is connected with a second threaded supporting rod 27 in the inner cavity, and the second threaded supporting rod 27 is rotationally connected with the hollow supporting base 21.

[0031] Further, the two positioning support frames 24 are both screw transmissionally connected with the first threaded supporting rod 25 on one side, the hollow supporting base 21 is fixedly provided with two protective baffle plates 28 on the top, one end of the first threaded supporting rod 25 penetrating through the limiting sliding groove 23 and extending into the inner cavity of the hollow supporting base 21 is rotationally connected with the guide sliding support plate 26, and the inner cavity of the guide sliding support plate 26 is screw transmissionally connected with the second threaded supporting rod 27 rotationally connected with the hollow supporting base 21. The purpose of such arrangement is that when the second threaded supporting rod 27 is driven to rotate, the guide sliding support plate 26 can drive the positioning support frame 24 and the first threaded supporting rod 25 to horizontally move left and right on the top of the hollow supporting base 21, so as to be suitable for limiting and clamping the main shell 101 of different sizes, and when the first threaded supporting rod 25 is rotated, the positioning support frame 24 can drive the main shell 101 to move up and down on the outer wall thereof, thereby adjusting the overall installation height of the switchgear main body 1.

[0032] One end of the second threaded supporting rod 27 is fixedly connected with a first link gear rod 29, the hollow supporting base 21 is internally provided with an electric rotating rod 210, both ends of the electric rotating rod 210 are fixedly provided with a second link gear rod 211, and the second link gear rod 211 is transmissionally connected with the electric rotating rod 210 through a transmission belt 212.

[0033] Further, in combination with Figure 5As shown, one end of the two second threaded supporting rods 27 is fixedly connected with the first connecting gear rod 29, the inside of the hollow supporting base 21 is fixedly installed with the electric rotating rod 210, both ends of the electric rotating rod 210 are fixedly installed with the second connecting gear rod 211, the outer wall of the electric rotating rod 210 and the second connecting gear rod 211 are all engaged with the transmission belt 212, in actual use, the synchronous rotation of the two second connecting gear rods 211 can be realized by driving the electric rotating rod 210 to rotate, then combined with the setting of the transmission belt 212 and the first connecting gear rod 29, the synchronous rotation of the two second threaded supporting rods 27 is realized, then the synchronous driving of the two positioning supporting frames 24 to translate is realized, so that the main shell 101 is clamped and limited on both sides, and the main shell 101 is limited and fixed.
