Technical Field

[0001] This invention relates to the field of cable harness power cabinet technology, specifically to a power cabinet equipped with a cable harness limiting structure. Background Technology

[0002] A power distribution cabinet is a device used in power systems to control, protect, and distribute power. It is commonly used in power distribution, automation control, electrical protection, and power monitoring. The design and function of power distribution cabinets can be customized to meet different usage requirements and environmental conditions.

[0003] Patent publication number CN219123686U relates to an electrical cabinet with a cable bundle limiting structure, comprising an electrical cabinet body and a limiting plate. An mounting plate is fixedly installed on the inner wall of the electrical cabinet body via fixing bolts. A winding roller is fixedly installed on the front of the limiting plate, and a limiting disc is fixedly installed on the front of the winding roller. A limiting component for limiting the cable is provided on the front of the limiting plate. This patent first reserves a section of cable between two electrical components and winds it onto the winding roller. Then, it pushes the limiting block to retract into a sliding groove. Afterward, the cable is placed between the two limiting blocks, and the force of the compression spring resets the two limiting blocks, limiting the cable. Compared to existing technologies, this patent not only limits the cable to ensure neat cable arrangement, but also allows the reserved cable wound on the winding roller to be extended when the cable interface is damaged due to overload, avoiding the problem of insufficient cable length after cutting the cable interface.

[0004] In the aforementioned patent, a section of cable between two electrical components is reserved and wound onto a winding roller. Then, a limiting block is pushed to retract into a sliding groove. The force of the compression spring is used to reset the two limiting blocks and limit the cable. However, during the cable winding process, the cable may be wound in the same loop, which will obstruct airflow, reduce heat dissipation efficiency, and lead to cable damage. Therefore, a power cabinet with a cable bundling limiting structure that functions as a conductor when bundling cables is designed. Summary of the Invention

[0009] According to the above technical solution, the device includes a limiting device and a cleaning device. The limiting device includes a fixed plate, a telescopic spring rod, an arc plate, a sliding plate, a convex plate, a sliding rod, and a fixed rod. The fixed plate is fixedly installed on the circumferential surface of the wire cylinder. The telescopic spring rod is fixedly installed on the top of the fixed plate.

A third sliding groove is provided on the surface of the placement frame. The sliding rod is slidably installed on the inner wall of the third sliding groove. The fixed rod is fixedly inserted through the surface of the sliding plate. This device limits the cable during cable laying under special circumstances, preventing damage to the cable under external force and avoiding damage to the cable structure due to inappropriate tension or torque.

[0010] According to the above technical solution, a telescopic spring rod is fixedly installed on the top of the sliding plate, and the surface of the arc plate is set as an arc surface to maintain a neat and clear cable layout.

[0011] According to the above technical solution, the fixed rod and the sliding rod are fixedly connected, and the surface of the convex plate is set as an arc surface, which facilitates later maintenance and troubleshooting and improves work efficiency.

[0012] According to the above technical solution, the cleaning device includes a turntable, a protective plate, a connecting rod, rollers, bristles, an S-shaped plate, a toothed block, a reciprocating screw two, a gear, a scraper, and a collection box. The turntable is fixedly installed on the circumferential surface of the rotating shaft, the protective plate is fixedly installed on the surface of the placement frame, the connecting rod is fixedly installed on the surface of the protective plate, the rollers are rotatably installed on the circumferential surface of the connecting rod, the bristles are fixedly installed on the surface of the turntable, the S-shaped plate is fixedly installed at the bottom of the placement frame, the toothed block is fixedly installed at the bottom of the S-shaped plate, a rotating groove is provided on the inner wall of the power cabinet, the reciprocating screw two is rotatably installed on the inner wall of the rotating groove, the gear is fixedly installed on the circumferential surface of the reciprocating screw two, the scraper is slidably installed on the circumferential surface of the reciprocating screw two, and the collection box is fixedly installed on the inner wall of the power cabinet to prevent the dust accumulated inside from affecting the normal operation of the electrical system and electronic components, causing equipment failure or performance degradation.

[0013] According to the above technical solution, the roller is in contact with the guide rail, the roller is in contact with the turntable, the scraper is connected to the reciprocating screw by a thread, and the inner wall of the power cabinet is provided with a dust leakage trough, which is centrally processed by the staff to collect the dust into a specific container or storage area to prevent the dust from spreading to other parts of the equipment.

[0014] This invention provides a power cabinet equipped with a cable bundle limiting structure. It has the following advantages:

[0015] (1) The power cabinet equipped with a cable bundle limiting structure allows the operator to pass the cable between the equipment through the wire drum and then wind the cable around the circumference of the winding drum. When the operator pulls out the placement rack, the reciprocating screw is connected to the wire drum by a thread. The reciprocating screw rotates and drives the wire drum to move back and forth, thereby guiding the cable winding. This avoids the problem of too many cables in the same loop after the cable winding is completed, which would cause the space between the cables to become crowded, obstruct airflow, and reduce heat dissipation efficiency. Then, the operator presses down the pressure plate according to the number and thickness of the cable loops. The pressure plate presses down and contacts and tightens the cable. Then, the operator inserts the pin at the same time to fix the limiting plate and the pressure plate, thereby fixing the tightened cable. This effectively prevents the cable from loosening or shifting in the power cabinet due to vibration, operation or external force, and reduces the chance of the cables coming into contact or rubbing against each other.

[0016] (2) The power cabinet equipped with a cable bundle limiting structure, when the conductor drum rotates clockwise to release the cable, drives the arc plate to rotate and approach and contact the convex plate. Then the arc plate rotates to approach and contact the convex plate. Under the action of the convex plate, the arc plate is tightly limited, which realizes the cable limiting when releasing the cable in special circumstances, and avoids the cable from being damaged by external force, thus being affected by inappropriate tension or torque, resulting in damage to the cable structure. The sliding plate moves upward to release the cable release limiting of the conductor drum, maintains the neat and clear layout of the cable, facilitates later maintenance and fault diagnosis, and improves work efficiency.

[0017] (3) The power cabinet equipped with a cable bundle limiting structure drives the turntable to rotate through the rotation of the rollers. The rotation of the turntable drives the brush to rotate around the rotating shaft. The rotation of the brush brushes off the dust attached to the inner wall of the power cabinet, preventing the dust accumulated inside from affecting the normal operation of the electrical system and electronic components, causing equipment failure or performance degradation. The reciprocating screw two is connected to the scraper through the thread. The rotation of the reciprocating screw two drives the scraper to move and scrape the dust brushed off by the brush towards the dust leakage trough. The dust falls into the collection box through the dust leakage trough and is then centrally processed by the staff, and the dust is collected in a specific container or storage area to prevent the dust from spreading to other parts of the equipment.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 One embodiment of the present invention is as follows: A power cabinet with a cable bundle limiting structure includes a power cabinet 1, a cable bundle device, a ventilation opening on the surface of the power cabinet 1, a fan 2 fixedly installed on the inner wall of the ventilation opening, a guide rail 3 fixedly installed on the inner wall of the power cabinet 1, and a cable bundle device including a placement frame 41, a rotating shaft 42, a reciprocating lead screw 43, a winding cylinder 44, a wire cylinder 45, a limiting plate 46, a limiting frame 47, a pressure plate 48, and a pin 49. The placement frame 41 is slidably installed on the inner wall of the guide rail 3, the rotating shaft 42 rotates through the surface of the placement frame 41, and the reciprocating lead screw... A screw 43 rotates through the surface of the placement rack 41. A winding drum 44 is fixedly installed on the circumferential surface of the rotating shaft 42. A wire tube 45 is slidably installed on the circumferential surface of the reciprocating screw 43. A limiting plate 46 is sleeved on the circumferential surface of the rotating shaft 42. A limiting frame 47 is slidably installed on the surface of the placement rack 41. A sliding groove is opened on the surface of the limiting frame 47. A pressure plate 48 is slidably installed on the inner wall of the sliding groove. A pin 49 is fixedly inserted through the surface of the pressure plate 48. The pressure plate 48 presses down to contact and press the cable. Then, the worker inserts the pin 49 at the same time to fix the limiting plate 46 and the pressure plate 48.

[0029] The surface of the limiting plate 46 is provided with a slot, and the pin 49 is fixed through the inner wall of the slot. The surface of the pressure plate 48 is set as an arc surface. The pin 49 is inserted into and fixed the limiting plate 46 and the pressure plate 48 at the same time.

[0030] The limiting plate 46 is sleeved on the circumferential surface of the reciprocating lead screw 43. The rotating shaft 42 is connected to the reciprocating lead screw 43 by a belt. The guide tube 45 is connected to the reciprocating lead screw 43 by a thread. The reciprocating lead screw 43 is connected to the guide tube 45 by a thread. The rotation of the reciprocating lead screw 43 drives the guide tube 45 to move back and forth.

[0031] In this embodiment, during operation: the operator passes the cable between devices through the cable reel 45, and then winds the cable around the circumference of the winding reel 44. When the operator pulls out the placement rack 41, the placement rack 41 moves away from the fan 2, causing the rotating shaft 42 to rotate. Simultaneously, the rotation of the rotating shaft 42 causes the winding reel 44 to wind up the cable. The rotation of the rotating shaft 42 also causes the reciprocating screw 43 to rotate. Since the reciprocating screw 43 is threadedly connected to the cable reel 45, the rotation of the reciprocating screw 43 causes the cable reciprocating, thus guiding the cable winding and preventing excessive cable in the same loop from becoming crowded between cables when winding is complete. Obstructed airflow reduces heat dissipation efficiency, leading to cable bending, indentation, or friction. Workers then press down the pressure plate 48 according to the cable's coil thickness. The pressure plate 48 contacts and clamps the cable. Next, workers insert the pin 49 simultaneously to secure the limiting plate 46 and the pressure plate 48, thus fixing the tightened cable. This effectively prevents the cable from loosening or shifting within the power cabinet 1 due to vibration, operation, or external forces, reducing the chance of contact or friction between cables and avoiding insulation damage caused by mutual friction, compression, or wear, thereby reducing the risk of electrical short circuits or faults.

[0032] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention includes a limiting device and a cleaning device. The limiting device includes a fixed plate 51, a telescopic spring rod 52, an arc plate 53, a sliding plate 54, a convex plate 55, a sliding rod 57, and a fixed rod 58. The fixed plate 51 is fixedly installed on the circumferential surface of the wire tube 45. The telescopic spring rod 52 is fixedly installed on the top of the fixed plate 51. The arc plate 53 is fixedly installed on the free end of the telescopic spring rod 52. A second sliding groove is opened on the surface of the placement frame 41. The sliding plate 54 is slidably installed on the inner wall of the second sliding groove. The convex plate 55 is slidably installed on the bottom of the sliding plate 54. A third sliding groove is opened on the surface of the placement frame 41. The sliding rod 57 is slidably installed on the inner wall of the third sliding groove. The fixed rod 58 is fixedly inserted through the surface of the sliding plate 54. The upward movement of the sliding rod 57 drives the fixed rod 58 to move, and the upward movement of the fixed rod 58 drives the sliding plate 54 to move.

[0033] A telescopic spring rod 56 is fixedly installed on the top of the sliding plate 54. The surface of the arc plate 53 is set as an arc surface. The sliding plate 54 moves and squeezes the telescopic spring rod 56 to deform. Then the sliding plate 54 moves upward to release the wire release limit on the wire cylinder 45.

[0034] The fixed rod 58 is fixedly connected to the sliding rod 57. The surface of the protruding plate 55 is set as an arc surface. When the sliding rod 57 is pulled upward, the upward movement of the sliding rod 57 drives the fixed rod 58 to move.

[0035] The cleaning device includes a turntable 61, a protective plate 62, a connecting rod 63, a roller 64, bristles 65, an S-shaped plate 66, a toothed block 67, a reciprocating screw 68, a gear 69, a scraper 610, and a collection box 611. The turntable 61 is fixedly mounted on the circumferential surface of the rotating shaft 42. The protective plate 62 is fixedly mounted on the surface of the placement frame 41. The connecting rod 63 is fixedly mounted on the surface of the protective plate 62. The roller 64 is rotatably mounted on the circumferential surface of the connecting rod 63. The bristles 65 are fixedly mounted on the surface of the turntable 61. The S-shaped plate 66 is fixedly mounted on the placement frame 41. At the bottom of the mounting frame 41, the toothed block 67 is fixedly installed at the bottom of the S-shaped plate 66. The inner wall of the power cabinet 1 is provided with a rotating groove. The reciprocating screw 68 is rotatably installed on the inner wall of the rotating groove. The gear 69 is fixedly installed on the circumferential surface of the reciprocating screw 68. The scraper 610 is slidably installed on the circumferential surface of the reciprocating screw 68. The collection box 611 is fixedly installed on the inner wall of the power cabinet 1. The rotation of the reciprocating screw 68 drives the scraper 610 to move and scrape the dust brushed off by the bristles 65 into the dust leakage trough. The dust falls into the collection box 611 through the dust leakage trough.

[0036] Roller 64 contacts guide rail 3 and turntable 61. Scraper 610 is connected to reciprocating screw 68 by thread. The inner wall of power cabinet 1 is provided with ash leakage groove. The placement rack 41 moves away from fan 2, which drives the connecting rod 63 to move. At the same time, the movement of the connecting rod 63 drives roller 64 to rotate.

[0037] In this embodiment, during operation: when the operator is reeling in the wire, the counterclockwise rotation of the wire drum 45 causes the fixed plate 51 to rotate. The rotation of the fixed plate 51 causes the telescopic spring rod 52 to rotate, which in turn causes the arc plate 53 to rotate. The arc plate 53 rotates and approaches and contacts the convex plate 55. Subsequently, under the action of the convex plate 55, the arc plate 53 moves closer to the axis of the wire drum 45. However, when the wire drum 45 rotates clockwise to unload the wire, it causes the arc plate 53 to rotate and approach and contact the convex plate 55. The arc plate 53 is then tightly stopped by the convex plate 55, thus achieving... In special circumstances, the cable is limited during cable laying to prevent damage from external forces, such as improper tension or torque, which could damage the cable structure. When workers need to inspect or remove the cable, they pull the sliding rod 57 upwards. At the same time, the upward movement of the sliding rod 57 moves the fixed rod 58, which in turn moves the sliding plate 54. The sliding plate 54 then moves and compresses the telescopic spring rod 56, causing it to deform. Subsequently, the sliding plate 54 moves upwards to release the cable laying limit on the conductor drum 45, maintaining a neat and clear cable layout, facilitating later maintenance and troubleshooting, and improving work efficiency.

[0038] When the staff pulls out the placement rack 41, the rack 41 moves away from the fan 2, causing the connecting rod 63 to move. Simultaneously, the movement of the connecting rod 63 causes the roller 64 to rotate, which in turn causes the turntable 61 to rotate. The rotation of the turntable 61 causes the brush bristles 65 to rotate around the pivot 42. The rotation of the brush bristles 65 brushes off the dust adhering to the inner wall of the power cabinet 1, preventing the accumulated dust from affecting the normal operation of the electrical system and electronic components, causing equipment malfunctions or performance degradation. Furthermore, if dust accumulates inside the equipment for a long time, it may affect the heat dissipation and performance of electrical components, and may even lead to short circuits or other malfunctions. The movement of the placement rack 41 causes the S-shaped plate 66 to move, which in turn causes the toothed block 67 to move. Because the toothed block 67 meshes with the gear 69, the movement of the toothed block 67 contacts and drives the gear 69 to rotate. At the same time, the rotation of the gear 69 drives the reciprocating screw 68 to rotate. Because the reciprocating screw 68 is connected to the scraper 610 by a thread, the rotation of the reciprocating screw 68 drives the scraper 610 to move, scraping the dust brushed off by the bristles 65 into the dust trough. The dust falls into the collection box 611 through the dust trough and is then centrally processed by the staff, who collect the dust into a specific container or storage area to prevent the dust from spreading to other parts of the equipment.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
