Two annular grooves are formed in the front inner wall of the dehumidification groove, two rotating rods are rotatably installed in the dehumidification groove, and cover-shaped activated carbon plates are fixedly sleeved on the two rotating rods, respectively. The heat in the cabinet body is discharged from the two air outlets through blowing, thereby achieving cooling and heat dissipation.

[0047] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited by the specific embodiments.

[0048] Unless otherwise clearly indicated, throughout the specification, the terms "comprise" or variations such as "comprises" or "comprising" will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

[0049] Referring to Figures 1-18 The present embodiment provides a technical solution as shown in the figure:

[0050] The application discloses an anti-impact low-voltage complete reactive power compensation cabinet, which comprises a cabinet assembly 1, wherein the cabinet assembly 1 comprises a cabinet 11 and heat dissipation windows 13 arranged on left and right side walls of the cabinet 11; a heat dissipation fan 2 is fixed to the middle of the rear side wall of the cabinet 11 and is used for active heat dissipation; a dehumidification assembly 3 is arranged on the top of the cabinet 11 and is used for absorbing water vapor in heavy rain to prevent internal elements of the cabinet assembly 1 from being damaged; and a dust screen 14 is fixed to the inner side of the heat dissipation window 13 and is used for dust prevention.

[0051] The dehumidification assembly 3 comprises a rain receiving structure 31 and a moisture absorbing structure 32; the rain receiving structure 31 comprises a rain receiving bucket 311 and a rotating rod 315 fixed to the middle of the bottom surface of the rain receiving bucket 311 through two left and right symmetrical upper supports 313; when the moisture absorbing structure 32 is not used, the rain receiving bucket 311 is arranged to be inclined backward; the top surface of the cabinet 11 is fixed with left and right symmetrical lower supports 314; the two ends of the rotating rod 315 penetrate through the two upper supports 313 and are rotationally connected with the corresponding lower supports 314; the bottom surface of the rain receiving bucket 311 is fixed with left and right symmetrical hoses 312; the two ends of the rotating rod 315 are fixed with first ropes 318 respectively; when it is drizzling, the rain receiving bucket 311 cannot store rainwater due to the existence of the hoses 312, the rain receiving bucket 311 cannot be turned over, the internal elements of the cabinet assembly 1 have certain waterproofness, and the raindrops and water vapor entering the cabinet assembly 1 are very little, and the heat dissipation fan 2 can quickly dry the water vapor, so that the rotating rod 315 cannot drive the subsequent moisture absorbing structure 32 to move and block the heat dissipation of the heat dissipation window 13.

[0052] When it is raining heavily, the rain receiving bucket 311 can quickly store rainwater due to the small water discharge capacity of the hoses 312 and the large rainfall, the rain receiving bucket 311 and the rotating rod 315 are rotated counterclockwise due to the gravity center offset of the rain receiving bucket 311, and then the first ropes 318 are retracted.

[0053] The cabinet 11 is rotationally connected with rotating plates 33 on the upper left and right inner walls; the bottom ends of the first ropes 318 are fixedly connected with rotating shafts of the corresponding rotating plates 33; the moisture absorbing structure 32 comprises a moisture absorbing plate 321, second ropes 322 fixedly connected with the outer edges of the rotating plates 33 and the middle of the moisture absorbing plate 321, and clamping mechanisms 323 fixed on the outer side walls of the moisture absorbing plate 321 and located at the front and rear edges; the second ropes 322 are connected with the outer edges of the rotating plates 33 and the moisture absorbing plate 321 through rope buckles; the inner wall of the cabinet 11 is provided with clamping groove 15 corresponding to the clamping mechanisms 323; when the first ropes 318 are retracted, the rotating plates 33 are rotated counterclockwise, the moisture absorbing plate 321 is pulled along the clamping groove 15 to be close to the heat dissipation window 13 through the second ropes 322, raindrops or a large amount of water vapor cannot enter the cabinet 11, and the air entering the cabinet 11 is dehumidified by the moisture absorbing plate 321 under the action of the heat dissipation fan 2.

[0054] In addition, as Figures 1-3 shown, the inner space of the rain bucket 311 is in a stepped shape with a large upper volume and a small lower volume, so that the center of gravity is located on the front side of the rotating rod 315 after the rain bucket 311 is filled with water, thereby driving the rotating rod 315 to rotate counterclockwise. The top end of the hose 312 is in communication with the lower space of the rain bucket 311 on the front side, and the diameter of the hose 312 is small. When it is raining lightly, the rainwater collected in the rain bucket 311 can quickly flow out of the hose 312. When it is raining heavily, the rainwater collected in the rain bucket 311 cannot quickly flow out of the hose 312, thereby allowing the rainwater to remain in the rain bucket 311, so that the rain bucket 311 can rotate. The rotating rod 315 is sleeved with a cylinder sleeve 316 on the outer wall between the two upper supports 313. The cylinder sleeve 316 is fixed to the top surface of the cabinet 11. A clockwork spring 317 is arranged between the cylinder sleeve 316 and the rotating rod 315. By arranging the clockwork spring 317, the rain bucket 311 can quickly return after the rain stops, and the rain bucket 311 can be fixed during normal use to avoid being blown by the wind.

[0055] Specifically, the left and right two heat dissipation windows 13 are arranged in an up-down staggered manner to increase the heat dissipation area. The moisture absorbing plate 321 is arranged on the inner wall of the cabinet 11 corresponding to the heat dissipation window 13 and below the heat dissipation window 13. The left and right side walls of the moisture absorbing plate 321 are provided with mesh openings and are filled with a plurality of staggered silica gels. A plurality of purlins 4 are fixed outside the heat dissipation window 13 to assist in blocking rainwater. The cabinet 11 is hingedly connected with the cabinet door 12 on the front side.

[0056] In addition, as Figures 4-10 shown, the clamping mechanism 323 includes a clamping strip 3231 and two movable clamping plates 3232 slidably connected to the front and rear sides of the clamping strip 3231. The movable clamping plates 3232 are provided in an extendable manner to facilitate installation and removal of the entire moisture absorbing plate 321. The clamping strip 3231 is provided with a movable cavity 3233 symmetrically arranged inside the front and rear sides. The movable clamping plates 3232 are slidably connected inside the movable cavity 3233. The movable cavity 3233 is fixed with a limiting rod 3234 symmetrically arranged inside the upper and lower sides. The outer end of the limiting rod 3234 is embedded in the inner wall of the corresponding movable clamping plate 3232 and is slidably connected. A return spring 3235 is sleeved between the inner end of the limiting rod 3234 and the corresponding movable clamping plate 3232. By arranging the return spring 3235, the movable clamping plate 3232 can be pushed outward during use, so that the movable clamping plate 3232 can clamp the clamping groove 15, thereby limiting the moisture absorbing plate 321.

[0057] In addition, as Figures 17-18As shown, the cleaning assembly 5 is arranged between the front and rear side walls of the heat dissipation window 13. The cleaning assembly 5 is arranged to clean the dust screen 14, so as to avoid dust accumulation affecting heat dissipation. The cleaning assembly 5 includes a cleaning plate 51 arranged on the top surface of the heat dissipation window 13, and a clamping plate 52 fixed on the front and rear sides of the cleaning plate 51. The inner side of the cleaning plate 51 is tightly attached to the dust screen 14. The cabinet 11 is provided with a clamping plate groove 16 for the clamping plate 52 to slide up and down. The clamping plate 52 and the clamping plate groove 16 are arranged to limit the cleaning plate 51, so that the cleaning plate 51 can slide up and down. The top surface of the cleaning plate 51 is provided with a plurality of magnetic buckles 54 fixed on the top surface of the heat dissipation window 13. The magnetic buckles 54 are arranged to limit the cleaning plate 51 on the top surface of the heat dissipation window 13 during normal use.

[0058] Further, the clamping strip 3231 is fixed with a driving tooth plate 324 in the middle of the outer side wall, the clamping plate 52 is fixed with a driven tooth plate 53 in the middle of the inner side wall, and the clamping strip groove 15 and the clamping plate groove 16 are rotatably connected with a gear 18 in the middle. The driving tooth plate 324 and the driven tooth plate 53 are respectively engaged with the gear 18. When the second rope 322 pulls the moisture absorption plate 321 to slide up along the clamping strip groove 15, the driving tooth plate 324 drives the driven tooth plate 53 to slide down through the gear 18, so as to drive the clamping plate 52 and the cleaning plate 51 to slide down along the clamping plate groove 16, and then clean the dust screen 14.

[0059] In addition, as shown in the drawings, Figures 11-16 The cabinet 11 is provided with a disassembly assembly 6 on the left and right outer side walls. The disassembly assembly 6 can quickly disassemble and replace the dehumidification assembly 3, so as to facilitate use. The disassembly assembly 6 includes a pressing plate 61 arranged on the outer side wall of the cabinet 11, a plurality of abutting plates 62 corresponding to the movable clamping plates 3232, and a plurality of pressing strip structures 63 corresponding to the abutting plates 62. The disassembly assembly 6 can quickly disassemble the moisture absorption plate 321. The abutting plate 62 penetrates through the outer side wall of the cabinet 11. The abutting plate 62 is slidably connected with the outer side wall of the cabinet 11. The outer wall of the abutting plate 62 is fixed with a flange. The flange prevents the abutting plate 62 from being separated from the cabinet 11, so that the entire disassembly assembly 6 cannot be used.

[0060] Specifically, the cabinet body 11 is provided with a pressing strip slot 17 on both sides of the card strip slot 15, and the pressing strip structure 63 is arranged in the pressing strip slot 17. The pressing strip slot 17 is communicated with the corresponding card strip slot 15, and the pressing strip structure 63 is composed of an outer pressing strip 631 and an inner pressing strip 632. The outer side of the outer pressing strip 631 is a slope, the inner end surface of the pressing plate 62 is a slope corresponding to the outer side of the outer pressing strip 631, the inner side of the inner pressing strip 632 is a slope, and the outer side of the movable card plate 3232 is a slope with the same inclination as the inner side of the inner pressing strip 632. When the pressing plate 61 is pressed, the pressing plate 62 is pushed to move forward to generate an inward force on the outer pressing strip 631, so that the entire pressing strip structure 63 moves to the side of the movable card plate 3232, and then the inner pressing strip 632 generates an inward force on the movable card plate 3232 to make the movable card plate 3232 retreat into the movable cavity 3233. At this time, the moisture absorption plate 321 can be separated and removed from the card strip slot 15.

[0061] Further, the left and right widths of the outer pressing strip 631 are greater than the left and right widths of the inner pressing strip 632. The outer pressing strip 631 is in sliding connection with the pressing strip slot 17. When installed, the slope of the movable card plate 3232 facilitates entering the card strip slot 15, and the slope of the movable card plate 3232 also pushes the inner pressing strip 632 outward to reset the pressing strip structure 63, preventing the outer pressing strip 631 from also entering the card strip slot 15 and causing the pressing strip structure 63 to fail to push outward when the movable card plate 3232 is installed.

[0062] The working principle of the anti-impact low-voltage complete reactive power compensation cabinet in the application is as follows:

[0063] When it is raining slightly, rainwater cannot be stored in the rain bucket 311 due to the presence of the hose 312, the rain bucket 311 will not be turned over, the internal elements of the cabinet body assembly 1 have a certain waterproofness, and few raindrops and water vapor can enter the inside of the cabinet body assembly 1. In addition, the presence of the cooling fan 2 can quickly dry the water vapor. At this time, the rotating rod 315 will not move to block the heat dissipation window 13 by driving the subsequent moisture absorption structure 32 through the first rope 318.

[0064] When it is raining heavily, the hose 312 has a small drainage capacity and the rainfall is large, so rainwater can be quickly stored in the rain bucket 311. At this time, the rain bucket 311 and the rotating rod 315 are rotated counterclockwise due to the gravity center offset of the rain bucket 311, and then the rotating plate 33 is rotated counterclockwise by driving the first rope 318, and then the moisture absorption plate 321 is pulled to slide up along the card strip slot 15 to adhere to the heat dissipation window 13 by the second rope 322, so as to prevent raindrops or a large amount of water vapor from entering the cabinet body 11. Under the action of the cooling fan 2, the air sucked in is dried by the moisture absorption plate 321 and then enters the cabinet body 11 to keep the inside dry.

[0065] When the slide 321 slides up, the driving tooth plate 324 drives the driven tooth plate 53 to slide down through the gear 18, and then drives the clamping plate 52 and the cleaning plate 51 to slide down along the clamping plate slot 16, and then the dustproof net 14 is cleaned.

[0066] When the slide 321 needs to be replaced due to the decrease of the moisture absorption capacity, the rope buckle between the second rope 322 and the slide 321 is unfastened, then the pressing plate 61 is pressed, the resisting plate 62 is pushed to move forward to give the outer resisting strip 631 an inward force, the whole pressing strip structure 63 moves to the side of the movable clamping plate 3232, then the inner resisting strip 632 gives the movable clamping plate 3232 an inward force, the movable clamping plate 3232 retreats into the movable cavity 3233, and then the slide 321 can be separated and disassembled from the clamping strip slot 15.

Many modifications and variations are possible in light of the above teachings without departing from the spirit or essential characteristics of the application.
