[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 8 , one embodiment of the present invention is: a power cabinet with a cable harness limiting structure includes a power cabinet 1, a harness device, a vent is opened on the surface of the power cabinet 1, a fan 2 is fixedly installed on the inner wall of the vent, a guide rail 3 is fixedly installed on the inner wall of the power cabinet 1, the harness device includes a placement frame 41, a rotating shaft 42, a reciprocating screw rod 43, a winding drum 44, a wire drum 45, a limiting plate 46, a limiting frame 47, a pressing plate 48 and a latch 49, the placement frame 41 is slidably installed on the inner wall of the guide rail 3, the rotating shaft 42 rotates and penetrates the surface of the placement frame 41, and the reciprocating screw rod A 43 rotates and passes through the surface of the placement rack 41, the winding reel 44 is fixedly installed on the circumferential surface of the rotating shaft 42, the wire reel 45 is slidably installed on the circumferential surface of the reciprocating screw rod 43, the limit plate 46 is sleeved on the circumferential surface of the rotating shaft 42, the limit frame 47 is slidably installed on the surface of the placement rack 41, the surface of the limit frame 47 is provided with a sliding groove 1, the pressure plate 48 is slidably installed on the inner wall of the sliding groove 1, the pin 49 is fixed and passes through the surface of the pressure plate 48, the pressure plate 48 presses down to contact and press the cable, and then the staff inserts and fixes the pin 49 at the same time.

[0021] A slot 1 is formed on the surface of the limit plate 46 , and a latch 49 is fixedly inserted through the inner wall of the slot 1. The surface of the pressure plate 48 is configured as an arc surface 1, and the latch 49 is inserted into and fixed to the limit plate 46 and the pressure plate 48 at the same time.

[0022] The limit plate 46 is sleeved with the circumferential surface of the reciprocating screw rod 43, a belt 1 is connected between the rotating shaft 42 and the reciprocating screw rod 43, the wire tube 45 is connected to the reciprocating screw rod 43 by threads, and the reciprocating screw rod 43 is connected to the wire tube 45 by threads, and the reciprocating screw rod 43 rotates to drive the wire tube 45 to move back and forth.

[0023] When the present embodiment is working, the staff passes the cables between the devices through the wire drum 45, and then winds the cables around the circumferential surface of the winding drum 44. When the staff pulls out the placement rack 41, the placement rack 41 moves away from the fan 2, driving the rotating shaft 42 to rotate. At the same time, the rotation of the rotating shaft 42 drives the winding drum 44 to retract the cables. The rotation of the rotating shaft 42 drives the reciprocating screw rod 1 43 to rotate. Since the reciprocating screw rod 1 43 is connected to the wire drum 45 by threads, the rotation of the reciprocating screw rod 1 43 drives the wire drum 45 to move back and forth, thereby guiding the retracted cables. This avoids the situation where there are too many cables in the same circle when the cables are retracted, and the space between the cables becomes crowded. The air circulation is hindered, resulting in reduced heat dissipation efficiency, which in turn causes the cable to bend, bend, bend or rub. The staff then presses down the pressure plate 48 according to the number of turns and thickness of the cable. The pressure plate 48 is pressed down to contact and tighten the cable. The staff then inserts the pin 49 and fixes the limit plate 46 and the pressure plate 48 at the same time, thereby fixing the tightened cable and effectively preventing the cable from loosening or shifting due to vibration, operation or external force in the power cabinet 1, reducing the chance of contact or friction between cables, and avoiding damage to the insulation layer due to friction, extrusion or wear between cables, thereby reducing the risk of electrical short circuit or failure.

[0025] A second telescopic elastic rod 56 is fixedly installed on the top of the sliding plate 54, and the surface of the arc plate 53 is set as an arc surface 2. The sliding plate 54 moves to squeeze the second telescopic elastic rod 56 to deform, and then the sliding plate 54 moves upward to release the wire release limit of the wire barrel 45.

[0026] The fixed rod 58 is fixedly connected to the sliding rod 57 , and the surface of the convex plate 55 is set as a three-arc surface. When the sliding rod 57 is pulled upward, the sliding rod 57 moves upward and drives the fixed rod 58 to move.

[0027] The cleaning device includes a turntable 61, a protective plate 62, a connecting rod 63, a roller 64, a brush 65, an S-shaped plate 66, a tooth block 67, a reciprocating screw rod 68, a gear 69, a scraper 610, and a collection box 611.

[0029] When the present embodiment is working, when the worker is winding up the wire, the wire drum 45 rotates counterclockwise, which drives the fixed plate 51 to rotate. The rotation of the fixed plate 51 drives the telescopic spring rod 1 52 to rotate. At the same time, the rotation of the telescopic spring rod 1 52 drives the arc plate 53 to rotate. The arc plate 53 rotates close to and contacts the convex plate 55. Subsequently, the arc plate 53 moves close to the axis of the wire drum 45 under the action of the convex plate 55. However, when the wire drum 45 rotates clockwise to release the wire, it drives the arc plate 53 to rotate close to and contact the convex plate 55. Subsequently, the arc plate 53 rotates close to and contacts the convex plate 55. The arc plate 53 is tightly limited under the action of the convex plate 55, so as to achieve In order to limit the position of the cable when laying out the cable under special circumstances, the cable is prevented from being damaged by external force, thereby being affected by inappropriate tension or torque, causing damage to the cable structure. When the staff needs to inspect or take out the cable, the sliding rod 57 is pulled upward, and at the same time, the sliding rod 57 moves upward to drive the fixed rod 58 to move, and the fixed rod 58 moves upward to drive the sliding plate 54 to move. At this time, the sliding plate 54 moves to squeeze the telescopic elastic rod 56 to deform, and then the sliding plate 54 moves upward to release the laying-out limit of the conductor barrel 45, so as to keep the cable neat and clear, facilitate later maintenance and troubleshooting, and improve work efficiency.

[0030] When the staff pulls out the placement rack 41, the placement rack 41 moves in the direction away from the fan 2, driving the connecting rod 63 to move. At the same time, the movement of the connecting rod 63 drives the roller 64 to rotate. The rotation of the roller 64 drives the turntable 61 to rotate. The rotation of the turntable 61 drives the bristles 65 to rotate around the rotating shaft 42. The rotation of the bristles 65 will brush off the dust attached to the inner wall of the power cabinet 1, so as to prevent the dust accumulated inside from affecting the normal operation of the electrical system and electronic components, causing equipment failure or performance degradation. If the dust accumulates inside the equipment for a long time, it may affect the heat dissipation and performance of the electrical components, and may even cause a short circuit or other failures. The movement of the placement rack 41 drives the S-shaped plate 66 to move, and the movement of the S-shaped plate 66 drives the tooth block 67 to move. Because the tooth block 67 is engaged with the gear 69, the tooth block 67 moves to contact and drive the gear 69 to rotate. At the same time, the rotation of the gear 69 drives the reciprocating screw rod 2 68 to rotate. Because the reciprocating screw rod 2 68 is connected to the scraper 610 by a thread, the rotation of the reciprocating screw rod 2 68 drives the scraper 610 to move and scrape the dust brushed off by the bristles 65 toward the ash leakage trough. The dust falls into the collection box 611 through the ash leakage trough, and then the staff will carry out centralized processing and collect the dust in a specific container or storage area to prevent the dust from spreading to other parts of the equipment.
