Description

Technical Field

[0001] The invention relates to the technical field of power cabinets, and in particular to a power cabinet capable of preventing incoming wires from being entangled. Background Art

[0002] Electricity is an energy source that uses electrical energy as a driving force. Invented in the 1870s, the invention and application of electricity set off the second climax of industrialization. It has become one of the three scientific and technological revolutions that have occurred in the world since the 18th century in human history. Since then, technology has changed people's lives. The power cabinet refers to a combination of electrical control cabinets that provide power for the normal operation of the entire machine, including contactors, frequency converters, high-voltage cabinets, transformers, etc. The power cabinet has the functions of supplying power to electrical equipment, starting equipment, monitoring equipment operating conditions, and protecting electrical equipment. It plays an important role in many fields such as industrial production, construction, and commercial operations, ensuring the stability of the power system and the normal operation of equipment.

[0003] The distribution cabinet arranges the electrical components, instruments, switches and lines neatly through the distribution board, and the cable is an important part of the distribution cabinet. However, when the cable is in use, when the cable is too long, different wiring requirements and different line layout methods will cause the lines to easily get entangled with each other, and it is easy to cause the connecting wires inside the distribution cabinet to bend. Some distribution boxes have poor dustproof effects, and dust is easy to accumulate over time, affecting the conductivity of the connection between the cable and the electronic components. Summary of the invention

[0004] To achieve the above purpose, the present invention is implemented through the following technical solutions: a power cabinet capable of preventing incoming wires from being entangled, comprising a cabinet body, a box body is arranged inside the cabinet body, and by arranging a double shell of the cabinet body and the box body, the outer shell can withstand external mechanical impact, collision and harsh environmental conditions, and enhance the protection performance, the front end hinge of the cabinet body is connected with a cabinet door, the outer bottom of the cabinet body is provided with an air inlet, and the rear end top of the cabinet body is provided with an air outlet;

[0005] A cable assembly, which is fixedly installed on one side of the cabinet close to the air outlet;

[0006] Wherein, the cable arrangement assembly includes a fixing frame, which is fixedly connected to the cabinet, the fixing frame opening faces the air inlet, and an annular groove is provided on the outer side of the fixing frame. Since too many cables are concentrated at the inlet, they squeeze each other, which affects the heat dissipation and causes heat accumulation. When working, the fan works, so that air enters the shell from the air inlet, flows to the inside of the fixing frame along the through hole, and then the air flows from the annular groove to the gap between the box body and the shell, and finally flows out from the air outlet. The double shell design can form a good air duct, promote air circulation, help the heat dissipation of internal electrical components, reduce the risk of overheating, improve the reliability and service life of the equipment, and then perform heat dissipation treatment on the cables at the inlet. A positioning assembly is fixedly connected to the middle of the annular groove, a rotating shaft is fixedly connected to the inner wall of the fixing frame, and a turntable is rotatably connected to the outer side of the rotating shaft. The turntable and the annular groove are located on the same vertical plane, and a groove is provided on the outer side of the turntable.

[0007] Preferably, the positioning assembly includes a limiting cylinder, the limiting cylinder is fixedly connected to the fixing frame, the top of the limiting cylinder is fixedly connected to a return spring, the end of the return spring away from the limiting cylinder is fixedly connected to a fixing sleeve, the inner wall of the fixing sleeve is slidably connected to the outer side of the limiting cylinder, the outer side of the fixing sleeve is fixedly connected to a spring plate, the end of the spring plate away from the fixing sleeve is fixedly connected to a connecting rod, the connecting rod passes through the fixing frame through an annular groove, and the end of the connecting rod away from the spring plate is fixedly connected to the positioning rod. When working, the cable passes through the cylinder, rotates along the turntable, and passes out of the limiting cylinder. When the cable surplus is too long, under the action of its own gravity, the surplus cable exerts a force on the fixing sleeve, the fixing sleeve squeezes the return spring, and the fixing sleeve slides downward on the outer side of the limiting cylinder, and the fixed sleeve drives the connecting rod to move downward, so that The positioning rod drives the turntable to rotate, and when the turntable rotates, extrusion is generated between the positioning rod and the positioning rod, and the spring plate is stretched and deformed by the force, so that the connecting rod moves away from the fixing sleeve. Under the elastic force of the spring plate, the positioning rod is reset and continues to squeeze the turntable, and the turntable continues to reel up, thereby preventing the wire from being too long and messy in the cabinet. When the cable is too tight, the tension of the cable increases, and the fixed sleeve is forced to drive the reset spring to stretch, so that the positioning rod moves away from the turntable. Under the tension of the cable, the turntable pays out the wire, thereby preventing the cable from being easily broken in a taut state for a long time. The positioning rod is located inside the groove, and a fixing ring is fixedly connected to the outer side of the connecting rod. By setting the fixing ring, the connecting rod is prevented from detaching from the limiting cylinder. The fixing sleeve is slidably connected to the fixing ring, and the fixing sleeve is located inside the fixing ring. There are two spring plates, and the two spring plates are symmetrically arranged with the fixing sleeve as the center.

[0008] The fixing frame is fixedly connected to a limiting component at the outer side away from the air inlet. There are multiple limiting components, which are arranged and distributed on the fixing frame. The limiting component and the positioning component are arranged on adjacent vertical planes.

When working, the cable is passed through the cylinder, and during the process of entering the line, the elastic performance of the compression spring makes the ball closely contact with the outer side of the cable, thereby limiting the cable at the entry point to prevent the cables from getting entangled with each other and easily causing the cables inside the power cabinet to bend. By setting the ball, rolling friction is used instead of sliding friction, so that the friction between the positioning block and the cable is reduced during the movement of the cable. At this time, the surface of the cable entering the shell is cleaned by the cleaning brush arranged at the entry point, and at the same time, the cleaning brushes arranged on the fixed frame and the cylinder are used The sealing plate at the connection prevents dust from entering the power cabinet and avoids dust from covering the surface of the heat sink and electrical components, which affects the dissipation of heat, causing the temperature inside the power cabinet to rise, accelerating the aging of the equipment, and reducing the performance and service life of the equipment. A slide groove is arranged inside the positioning block, and a compression spring is fixedly connected to the inner wall of the slide groove, and a round rod is slidably connected to the inner wall of the slide groove, and the round rod passes through the positioning block and extends to the inside of the positioning block, and one end of the compression spring away from the slide groove is fixedly connected to the round rod, and one end of the round rod away from the compression spring is fixedly connected to the limit frame, and the inner wall of the limit frame is rotatably connected with a ball, and a sealing plate is arranged at one end of the positioning block close to the fixed frame, and the sealing plate is set to a wavy shape. There are multiple sealing plates, and the multiple sealing plates are divided into two groups, one group of sealing plates is fixedly connected to the positioning block, and the other group of sealing plates is fixedly connected to the fixed frame, and the two groups of sealing plates are alternately arranged.

[0010] Preferably, the cabinet includes an outer shell, which is hingedly connected to the cabinet door, and a heat sink is fixedly connected to the interval between the outer shell and the box body. A cooling pipe is provided inside the outer shell, and the cooling pipe is bent in multiple sections. The heat sink and the cooling pipe are alternately arranged. By arranging the cooling pipe and the heat sink in the middle of the outer shell and the box body, and the cooling pipe and the heat sink are alternately arranged, the heat inside the box body is transferred to the cooling pipe through the heat sink. With the flow of cold water circulating inside the cooling pipe, the heat dissipation of the internal electrical components is facilitated, the risk of overheating is reduced, and the reliability and service life of the equipment are improved. The cooling pipe is located on two adjacent sides of the air inlet, and a slide rail is provided at the interval between the outer shell and the box body. The slide rail is connected to the outer shell Fixed connection, the inner wall of the slide rail is slidably connected with a slider, the middle of the slider is provided with a circular hole, the cable is passed through the circular hole, when working, multiple slide rails are arranged in the vertical direction, and multiple sliders are arranged inside each slide rail, so that the cables distributed at different heights can be clamped and fixed, so that they can be arranged in an orderly manner to prevent short circuits caused by the connection wires being entangled together, and at the same time, by adjusting the position of the slider in the slide rail, the distance between the cables can be adjusted, so that high-power cables should be arranged separately from low-power cables to reduce mutual interference and heating problems, a through hole is provided inside the shell, a fan is fixedly connected to the inner wall of the through hole, the through hole is connected to the air inlet, and a square hole is provided on the side of the box body close to the slide rail.

[0012] 1. The power cabinet capable of preventing the incoming wire from being entangled has a connecting rod away from the fixing sleeve. Under the elastic force of the spring plate, the positioning rod is reset and the turntable is continuously squeezed, and the turntable is continuously wound, thereby preventing the wire from being too long and messy in the cabinet. When the cable is too tight, the tension of the cable increases, and the fixing sleeve is forced to stretch the reset spring, so that the positioning rod is away from the turntable. Under the tension of the cable, the turntable pays out the wire, thereby preventing the cable from being easily broken when it is in a tight state for a long time.

[0013] Second, the power cabinet, which can prevent the incoming wires from getting entangled, can form a good air duct through the double-shell design, promote air circulation, help dissipate heat of internal electrical components, reduce the risk of overheating, improve the reliability and service life of the equipment, and then dissipate heat for the cables at the incoming wires.

[0014] 3. The power cabinet capable of preventing the incoming wire from being entangled uses rolling friction instead of sliding friction by setting a spherical ball, so that the friction between the positioning block and the cable is reduced during the movement of the cable. At this time, the cleaning brush set at the incoming wire is used to clean the surface of the cable entering the shell.

[0015] Fourth, the power cabinet capable of preventing the incoming wires from being entangled prevents dust from entering the power cabinet by means of a sealing plate provided at the connection between the fixed frame and the cylinder, thereby preventing dust from covering the surface of the heat sink and electrical components, thereby affecting the heat dissipation, causing the temperature inside the power cabinet to rise, accelerating the aging of the equipment, and reducing the performance and service life of the equipment.

[0016] 5. The power cabinet capable of preventing the incoming wires from being entangled has a cooling pipe and a heat sink disposed in the middle of the outer shell and the box body, and the cooling pipe and the heat sink are disposed alternately at intervals, so that the heat inside the box body is transferred to the cooling pipe through the heat sink. As the cold water circulates inside the cooling pipe, the heat is helped to be dissipated from the internal electrical components, thereby reducing the risk of overheating and improving the reliability and service life of the equipment.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0029] The first embodiment, as Figures 1 to 8 As shown, the present invention provides a technical solution: a power cabinet capable of preventing incoming wires from being entangled, comprising a cabinet body 1, a box body 4 is arranged inside the cabinet body 1, and an outer shell 11 can withstand external mechanical shocks, collisions and harsh environmental conditions by arranging a double shell of the cabinet body 1 and the box body 4, thereby enhancing the protection performance, a cabinet door 2 is hingedly connected to the front end of the cabinet body 1, an air inlet 5 is provided at the outer bottom of the cabinet body 1, and an air outlet 6 is provided at the rear end top of the cabinet body 1;

[0030] The cable assembly 3 is fixedly mounted on one side of the cabinet 1 close to the air outlet 6;

[0031] The cable assembly 3 includes a fixed frame 31, which is fixedly connected to the cabinet 1. The opening of the fixed frame 31 faces the air inlet 5. An annular groove 33 is provided on the outer side of the fixed frame 31. Since too many cables are concentrated at the inlet, they squeeze each other, which affects the heat dissipation and causes heat accumulation. When working, the fan 18 works, so that air enters the shell 11 from the air inlet 5, flows to the inside of the fixed frame 31 along the through hole 17, and then the air flows from the annular groove 33 to the gap between the box body 4 and the shell 11, and finally flows out from the air outlet 6. The double shell design can form a good air duct, promote air circulation, help the heat dissipation of internal electrical components, reduce the risk of overheating, improve the reliability and service life of the equipment, and then perform heat dissipation treatment on the cables at the inlet. A positioning assembly 34 is fixedly connected to the middle of the annular groove 33, and a rotating shaft 35 is fixedly connected to the inner wall of the fixed frame 31. A turntable 36 is rotatably connected to the outer side of the rotating shaft 35. The turntable 36 and the annular groove 33 are located on the same vertical plane, and a groove 37 is provided on the outer side of the turntable 36.

[0032] The positioning assembly 34 includes a limiting cylinder 341, which is fixedly connected to the fixing frame 31. A reset spring 342 is fixedly connected to the top of the limiting cylinder 341. The end of the reset spring 342 away from the limiting cylinder 341 is fixedly connected to a fixing sleeve 343. The inner wall of the fixing sleeve 343 is slidably connected to the outer side of the limiting cylinder 341. The outer side of the fixing sleeve 343 is fixedly connected to a spring plate 344. The end of the spring plate 344 away from the fixing sleeve 343 is fixedly connected to a connecting rod 345. The connecting rod 345 passes through the annular groove 33 to fix The end of the connecting rod 345 away from the spring plate 344 is fixedly connected to the positioning rod 347. When working, the cable passes through the cylinder 321, rotates along the turntable 36, and passes through the limiting cylinder 341. When the cable surplus is too long, under the action of its own gravity, the excess cable exerts force on the fixing sleeve 343, and the fixing sleeve 343 squeezes the return spring 342. The fixing sleeve 343 slides downward on the outer side of the limiting cylinder 341, and the fixing sleeve 343 drives the connecting rod 345 to move downward, so that the fixing sleeve 343 can be used to fix the return spring 342. The positioning rod 347 drives the turntable 36 to rotate. When the turntable 36 rotates, it is squeezed between the positioning rod 347, and the spring plate 344 is stretched and deformed by force, so that the connecting rod 345 is away from the fixing sleeve 343. Under the elastic force of the spring plate 344, the positioning rod 347 is reset and continues to squeeze the turntable 36. The turntable 36 is continuously reeled, thereby preventing the wire from being too long and messy in the cabinet. When the cable is too tight, the tension of the cable increases, and the fixing sleeve 343 is forced to drive the reset spring 342 to stretch, so that the positioning rod 347 is away from the turntable 3 6. Under the pulling force of the cable, the turntable 36 releases the cable to prevent the cable from being easily broken when it is in a taut state for a long time. The positioning rod 347 is located inside the groove 37. The outer side of the connecting rod 345 is fixedly connected with a fixing ring 346. By setting the fixing ring 346, the connecting rod 345 is prevented from being separated from the limiting cylinder 341. The fixing sleeve 343 is slidably connected with the fixing ring 346. The fixing sleeve 343 is located inside the fixing ring 346. There are two spring plates 344, and the two spring plates 344 are symmetrically arranged with the fixing sleeve 343 as the center.

[0033] The fixing frame 31 is fixedly connected to the outer side away from the air inlet 5 with a limiting assembly 32 . There are multiple limiting assemblies 32 , which are arranged and distributed on the fixing frame 31 . The limiting assembly 32 and the positioning assembly 34 are arranged on adjacent vertical planes.

[0034] The second embodiment is based on the first embodiment. Figures 9 and 10As shown, the limiting assembly 32 includes a cylinder 321, the cylinder 321 is fixedly connected to the fixed frame 31, the inner wall of the cylinder 321 is fixedly connected with a positioning block 322, the positioning block 322 is set to be convex in the middle, the inner wall of the positioning block 322 away from the fixed frame 31 is fixedly connected with a cleaning brush 323, the cleaning brush 323 is arranged circumferentially on the inner wall of the positioning block 322, and the angle between the cleaning brush 323 and the positioning block 322 is an acute angle. When working, the cable passes through the cylinder 321, and in the process of feeding the cable, the elastic performance of the compression spring 325 is The ball 328 is in close contact with the outside of the cable, thereby limiting the position of the cable at the incoming line to prevent the cables from being entangled with each other and easily causing the cables inside the power cabinet to bend. By setting the ball 328, rolling friction is used instead of sliding friction, so that the friction between the positioning block 322 and the cable is reduced during the movement of the cable. At this time, the cleaning brush 323 set at the incoming line is used to clean the surface of the cable entering the shell 11. At the same time, a sealing plate 329 set at the connection between the fixed frame 31 and the cylinder 321 is used to prevent dust from entering the power cabinet, and to prevent dust from covering the surface of the heat sink and electrical components, affecting the heat dissipation, causing the temperature inside the power cabinet to rise, accelerating the aging of the equipment, and reducing the performance and service life of the equipment. A slide groove 324 is provided inside the positioning block 322, and a compression spring 325 is fixedly connected to the inner wall of the slide groove 324. A round rod 326 is slidably connected to the inner wall of the slide groove 324. The round rod 326 penetrates the positioning block 322 and extends to the inside of the positioning block 322. The compression spring 325 is away from the slide groove 324. The end is fixedly connected to the round rod 326, and the end of the round rod 326 away from the compression spring 325 is fixedly connected to the limit frame 327. The inner wall of the limit frame 327 is rotatably connected with a ball 328. A sealing plate 329 is provided at one end of the positioning block 322 close to the fixed frame 31. The sealing plate 329 is set in a wavy shape. There are multiple sealing plates 329, and the multiple sealing plates 329 are divided into two groups. One group of sealing plates 329 is fixedly connected to the positioning block 322, and the other group of sealing plates 329 is fixedly connected to the fixed frame 31, and the two groups of sealing plates 329 are alternately arranged.

[0035] The third embodiment is based on the first and second embodiments. Figures 4 to 5As shown, the cabinet 1 includes an outer shell 11, which is hingedly connected to the cabinet door 2, and a heat sink 13 is fixedly connected at the interval between the outer shell 11 and the box body 4. A cooling pipe 12 is arranged inside the outer shell 11, and the cooling pipe 12 is bent in multiple sections. The heat sink 13 and the cooling pipe 12 are alternately arranged. By arranging the cooling pipe 12 and the heat sink 13 in the middle of the outer shell 11 and the box body 4, and the cooling pipe 12 and the heat sink 13 are alternately arranged, the heat inside the box body 4 is transferred to the cooling pipe 12 through the heat sink 13. With the flow of cold water circulating inside the cooling pipe 12, the heat dissipation of the internal electrical components is facilitated, the risk of overheating is reduced, and the reliability and service life of the equipment are improved. The cooling pipe 12 is located on the adjacent two sides of the air inlet 5, and a slide rail 14 is arranged at the interval between the outer shell 11 and the box body 4. The slide rail 14 is connected to the cooling pipe 12. The outer shell 11 is fixedly connected, and a slider 15 is slidably connected to the inner wall of the slide rail 14. A circular hole 16 is opened in the middle of the slider 15, and the cable is passed through the circular hole 16. When working, multiple slide rails 14 are arranged in the vertical direction, and multiple sliders 15 are arranged inside each slide rail 14, so that cables distributed at different heights can be clamped and fixed, so that they can be arranged in an orderly manner to prevent short circuits caused by the connection wires being entangled together. At the same time, by adjusting the position of the slider 15 in the slide rail 14, the distance between the cables can be adjusted, so that high-power cables should be arranged separately from low-power cables to reduce mutual interference and heating problems. A through hole 17 is opened inside the outer shell 11, and a fan 18 is fixedly connected to the inner wall of the through hole 17. The through hole 17 is connected to the air inlet 5, and a square hole 19 is opened on the side of the box 4 close to the slide rail 14.

[0036] When in use, the cable is passed through the cylinder 321. During the process of entering the cable, the elastic performance of the compression spring 325 makes the ball 328 in close contact with the outside of the cable, thereby limiting the cable at the entry point. The cable then revolves along the turntable 36 and passes through the limiting cylinder 341. The cable further passes through the circular hole 16 and enters the interior of the box 4 from the square hole 19.

[0037] When the cable surplus is too long, under the action of its own gravity, the surplus cable exerts a force on the fixing sleeve 343, and the fixing sleeve 343 squeezes the reset spring 342, and the fixing sleeve 343 slides downward on the outer side of the limit cylinder 341, and the fixing sleeve 343 drives the connecting rod 345 to move downward, so that the positioning rod 347 drives the turntable 36 to rotate, and when the turntable 36 rotates, it is squeezed between the positioning rod 347, and the spring plate 344 is stretched and deformed by the force, so that the connecting rod 345 is away from the fixing sleeve 343. Under the elastic force of the spring plate 344, the positioning rod 347 is reset and continues to squeeze the turntable 36, and the turntable 36 is continuously reeled, thereby preventing the wire surplus from being too long and messy in the cabinet. When the cable is too tight, the tension of the cable increases, and the fixing sleeve 343 is forced to drive the reset spring 342 to stretch, so that the positioning rod 347 is away from the turntable 36. Under the tension of the cable, the turntable 36 releases the wire, so as to avoid the cable being easily broken when it is in a tight state for a long time.

[0038] At the same time, the fan 18 works, so that air enters the interior of the outer shell 11 from the air inlet 5, flows along the through hole 17 to the interior of the fixed frame 31, and then the airflow flows from the annular groove 33 to the gap between the box body 4 and the outer shell 11, and finally flows out from the air outlet 6. The double shell design can form a good air duct, promote air circulation, and help dissipate heat from internal electrical components.
