Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, in particular to an electrical cabinet capable of automatic cleaning and dust prevention. Background Art

[0002] Power cabinets are generally installed in electrical engineering equipment. The stability of electricity in electrical engineering equipment needs to be guaranteed by qualified equipment. Power cabinets are a general term for motor control centers. Power cabinets are suitable for occasions with relatively dispersed loads and fewer circuits, and motor control centers are used in occasions with concentrated loads and more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] In the prior art, such as Chinese patent publication number CN111787733A, an electrical cabinet is disclosed, including a cabinet body, a supporting and moving structure, a ventilation and heat dissipation structure and a drying structure. The supporting and moving structure is connected to the bottom of the cabinet body, and the supporting and moving structure includes a first rotating shaft, a swing rod, a long strip, a second rotating shaft, a supporting rod, a lifting rod, a foot, a roller and a hydraulic cylinder. The bottom surface of the cabinet body is connected to four rectangular and vertically arranged long strips, and the outer end surface of the bottom end of the long strip is rotatably connected to the first rotating shaft. The outer side wall of the first rotating shaft is fixedly connected to three annularly arranged swing rods. The electrical cabinet provided by the invention has the advantages of being easy to walk and climb on step-like stairs, providing convenience for the staircase corridor transfer process, and walking and moving on the flat road surface through the self-rotation of the rollers. The operator needs to support the entire cabinet body to push, thereby completing the entire cabinet body transfer, and does not need to rely entirely on manual handling, which provides convenience for the transfer process.

[0004] Although the electrical cabinet in the above patent does not need to be completely dependent on manual handling, providing the advantage of convenience in the transportation process, the common electrical cabinet heat dissipation methods on the market are mainly natural heat dissipation and forced heat dissipation. Natural heat dissipation mainly relies on heat exchange between the outer casing of the electrical cabinet and the surrounding environment to dissipate heat. The heat dissipation effect is limited and it is difficult to meet the heat dissipation requirements of high-power electrical equipment. Forced heat dissipation usually uses fans to dissipate heat, forcibly accelerating the flow of air inside and outside the electrical cabinet to achieve the purpose of heat dissipation. However, most of the existing electrical cabinets only install one or several fans at specific locations, and mainly rely on airflow to passively take away the heat generated during the operation of the internal electrical parts, which is difficult to meet the heat dissipation requirements of high-power electrical cabinets.

[0005] Therefore, an automatic dust-proof electrical cabinet is proposed to solve the problems mentioned in the above background technology. Summary of the invention

[0034] The rear end of the fan shaft 403 extends to the rear side of the L-shaped plate 402 and the rear end of the fan shaft 403 is fixedly connected to the first bevel gear 405. Two plane bearings 407 are symmetrically installed on the top of the movable beam 401. The top of the plane bearing 407 is installed with a second bevel gear 406. The inner surface wall of the second bevel gear 406 is slidably connected to the first rotating shaft 203, and the inner surface wall of the plane bearing 407 and the outer surface of the first rotating shaft 203 are in a non-contact state.

[0035] The top of the beam 201 is connected to a third pulley 208 through an axis rotation near the edge of one side, and a second transmission belt 209 is arranged between the outer surfaces of the third pulley 208 and the second pulley 207. The small gear 206 is meshed with the large gear 301, and an eccentric column 302 is fixedly connected to the top of one of the large gears 301 near the center of the circle.

When the pinion 206 rotates, the first rotating shaft 203 at the bottom thereof will rotate synchronously, and the other first rotating shaft 203 will be driven to rotate along with the cooperation of the two first pulleys 204 and the first transmission belt 205.

In this device, a large number of evenly arranged fan blades 404 located on the rear side of the electrical component 15 can be synchronously driven by only one motor 210, which has the effect of reducing costs and saving energy and reducing emissions. In addition, a large number of fan blades 404 directly blow air to the electrical component 15, which can effectively force the heat dissipation thereof, meeting the heat dissipation requirements of high-power electrical cabinets.

[0037] Embodiment 2: Figure 2-Figure 8 As shown, the difference between the embodiment and the basis is that the outer surface of the beam 201 is symmetrically provided with an avoidance opening 202 near the pinion 206, the bottom of the beam 201 is symmetrically fixedly connected with a bracket 211 near the avoidance opening 202, the outer surface of the movable beam 401 is symmetrically embedded with threaded sleeves 408 near both ends, the inner surface walls of the threaded sleeves 408 are threadedly connected with threaded columns 409, and a plurality of threaded columns 409 are respectively fixedly connected to the outer surfaces of two connecting shafts 410, the avoidance opening 202 is mainly used to avoid the crankshaft 303, the bracket 211 is mainly used to support the bottom end of the crankshaft 303 to keep it stable when rotating, the threaded columns 409 are divided into two groups, and are connected in series by two connecting shafts 410, when the connecting shaft 410 rotates, the threaded columns 409 on the surface will rotate synchronously.

[0038] A crankshaft 303 is fixedly connected to the bottom center of the large gear 301, and the crankshaft 303 and the avoidance opening 202 are located in corresponding positions. The bottom end of the crankshaft 303 is rotatably connected to the outer surface of the bracket 211, and the front and rear outer surfaces of the moving block 304 are fixedly connected to sliders 305, and the outer surface of the slider 305 is slidably connected to a slide rail 306, and the slide rail 306 is fixedly connected to the top of the beam 201, and the crankshaft 303 journal and the inner waist groove of the moving block 304 fit together. The slide rail 306 fixed on the top of the beam 201 is mainly used to limit the slider 305 on the surface of the moving block 304, so that the moving block 304 can only move in a straight line left and right at the top of the beam 201, and the journals in the middle of the two crankshafts 303 are in the same direction and rotate at the same speed, ensuring that the two moving blocks 304 move in the same direction when they move back and forth.

[0039] The outer surfaces of the opposite sides of the two moving blocks 304 are fixedly connected with racks 307, and the outer surface of the racks 307 is meshed with a reciprocating gear 308. The bottom of the reciprocating gear 308 is fixedly connected with a connecting column 309. The connecting column 309 rotates through the top of the beam 201 and extends downward. When the racks 307 move with the moving blocks 304, they can drive the reciprocating gear 308 to rotate. Since the racks 307 move back and forth left and right, the reciprocating gear 308 will continuously rotate forward and reverse repeatedly.

[0040] A coupling 310 is installed at the bottom end of the connecting column 309, and the bottom of the coupling 310 is fixedly connected to the top of the connecting shaft 410. By setting the coupling 310 to connect the connecting shaft 410 and the connecting column 309, the impact caused by the sudden turn of the connecting column 309 can be reduced.

[0041] The present invention is used in steps. When the motor 210 drives the small gear 206 to rotate, the small gear 206 will synchronously drive the large gear 301 meshing with it to rotate. The rotation of the large gear 301 can drive the crankshaft 303 to rotate synchronously. During the rotation of the crankshaft 303, the eccentric journal of the crankshaft 303 cooperates with the waist groove on the surface of the moving block 304 to drive the moving block 304 to reciprocate left and right on the top of the beam 201. At this time, the rack 307 that moves with the moving block 304 will drive the reciprocating gear 308 to repeatedly rotate forward and reverse during the movement, thereby cooperating with the connecting column 309 and the connecting rod 309 to rotate the reciprocating gear 308. The shaft 310 drives the connecting shaft 410 below to rotate forward and reversely. At this time, the threaded column 409 on the surface of the connecting shaft 410 will drive the threaded sleeve 408 and the movable beam 401 to repeatedly rise and fall under the action of the thread. At this time, the second bevel gear 406 follows the rise and fall of the movable beam 401, and at the same time follows the first rotating shaft 203 to rotate and slide on the surface of the first rotating shaft 203, so that the fan blades 404 move up and down while blowing air, further expanding the blowing range of the fan blades 404, so that the electrical components 15 at different positions can be quickly taken away by the airflow, effectively improving the heat dissipation effect.

[0042] Embodiment 3: Figure 4 , Figure 5 and Fig.10 As shown, the difference between the basis of the embodiment is that one of the synchronous pulleys 501 is fixedly connected to the top of the third pulley 208, a third transmission belt 502 is arranged between the outer surfaces of the two synchronous pulleys 501, a reciprocating screw rod 504 is fixedly connected to the bottom of the other synchronous pulley 501, the reciprocating screw rod 504 is rotatably connected to the rear surface of the cabinet body 1 through a mounting block, a movable sleeve 505 is installed on the outer surface of the reciprocating screw rod 504, and a horizontal brush plate 506 is fixedly connected to the outer surface of the movable sleeve 505, and the two synchronous pulleys 501 are fixedly connected to the third transmission belt 502. Under the action of the driving belt 502, it can rotate synchronously. Therefore, the synchronous pulley 501 on the inner side of the cabinet 1 that rotates following the third pulley 208 can transmit the rotational force to the synchronous pulley 501 on the rear side of the cabinet 1. No additional driving source is required to drive the reciprocating screw 504 to rotate. The movable sleeve 505 is installed on the surface of the reciprocating screw 504 through the internal crescent block. Therefore, when the reciprocating screw 504 continues to rotate, the movable sleeve 505 will follow the thread path to reciprocate up and down, thereby driving the brush plate 506 to fit the filter back plate 16 for moving and cleaning.

[0043] The outer surface of the brush plate 506 is located away from the reciprocating screw rod 504, and a movable column 507 is movably penetrated inside. The outer surface of the movable column 507 is sleeved with a limit sleeve 508 near the two ends. The limit sleeve 508 is fixedly connected to the rear surface of the cabinet 1. The top of the movable column 507 is rotatably connected to the swing rod 503, and the front end of the swing rod 503 is rotatably connected to the eccentric column 302. The surface of the limit sleeve 508 is provided with an arc-shaped waist groove, and the path center of the arc-shaped waist groove is consistent with the center of the reciprocating screw rod 504, which is used to limit the moving path of the movable column 507. The eccentric column 302 rotating with the large gear 301 can mobilize the front end of the swing rod 503 to perform a circular motion. At this time, the swing rod 503 will drive the limited movable column 507 to swing back and forth, so that the brush plate 506 will switch between contact and non-contact states when cleaning the filter back plate 16, thereby avoiding the accumulation of cleaned impurities on the brush plate 506 and improving the dust removal effect.

[0044] The use steps of the present invention are as follows: when the external air enters the cabinet 1 through the filter back plate 16, the dust in the air will adhere to the surface of the filter back plate 16. At this time, the second pulley 207 driven by the motor 210 will drive the third pulley 208 to rotate and the synchronous pulley 501 on the top of the third pulley 208 to rotate through the second transmission belt 209. Under the action of the third transmission belt 502, the external synchronous pulley 501 will simultaneously drive the reciprocating screw rod 504 to rotate. When the reciprocating screw rod 504 rotates, the movable sleeve 505 on its surface will drive the brush plate 506 to reciprocate up and down along the reciprocating screw rod 504 under the action of the internal crescent block, thereby cleaning the impurities on the surface of the filter back plate 16. At the same time, the eccentric column 302 rotating with the large gear 301 cooperates with the swing rod 5 03 will drive the movable column 507 to reciprocate back and forth, and the position of the brush plate 506 near the left side is penetrated by the movable column 507, so that the brush plate 506 will continue to swing in a small range with the reciprocating screw rod 504 as the center during the up and down movement. Therefore, when the electrical cabinet is forced to dissipate heat, the brush plate 506 will reciprocate up and down on the surface of the filter back plate 16, and continue to swing back and forth, so that impurities in the air cannot adhere to the surface of the filter back plate 16 to form a blockage, which has the effect of automatically cleaning the air impurities and has a good use effect. According to the adhesion of impurities on the surface of the filter back plate 16, the motor 210 can be properly started to flip, so that the evenly distributed fan blades 404 blow air backwards, so that the impurities on the surface of the filter back plate 16 are effectively blown away during the cleaning process.

[0045] Among them, the electrical component 15 and the motor 210 are both existing technologies, and their components and operating principles are public technologies, which will not be explained in detail here.
