Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a switch cabinet reset component. Background Art

[0002] The main function of the switchgear is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. It is mainly suitable for various occasions such as power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mines, residential areas, high-rise buildings, etc. The reset component is one of the main structures of the switchgear, which can reset the switchgear door. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a switch cabinet with a reset assembly, which is disclosed in the publication number: CN217420879U, and includes a switch cabinet body, an L-shaped inner cavity, a universal wheel, a cabinet door, a rubber sealing strip, an installation groove, a rotating shaft, a fixing seat, a connecting plate, a winding wheel, a reversing wheel, a counterweight, a wire rope, a latch hole and a clamping hole. When the operator inspects the inside of the switch cabinet body, the cabinet door can be manually rotated and opened by the rotation of the rotating shaft, and the upper end of the rotating shaft will drive the winding wheel to rotate synchronously and rewind the wire rope. After the reversing wheel is reversed, the wire rope can drive the counterweight to slide upward along the inner wall surface of the L-shaped inner cavity. After completion, the cabinet door is loosened, and the counterweight block can move down and reset under the action of gravity, and then the wire rope is pulled in the opposite direction. The wire rope is released from the surface of the winding wheel and drives the winding wheel and the rotating shaft to rotate, which can drive the cabinet door to close automatically, avoiding the cabinet door being opened for a long time and a lot of dust and impurities being poured in; when repairing the components inside the switch cabinet, the cabinet door is rotated and opened to the extreme position. At this time, the counterweight block moves up to the extreme position, and then the pin is inserted into the pin hole. The end of the pin will be aligned and inserted into the clamping hole, so that the counterweight block can be clamped to prevent it from moving down due to gravity, thereby ensuring that the cabinet door can be continuously in the open state, which is convenient for maintenance operations.

[0004] In the above utility model, when the cabinet door is rotated, the winding wire rope is rotated by driving the rotating shaft to drive the winding wheel to rotate, which can drive the counterweight block to move upward along the L-shaped inner cavity, and finally a pin is used to penetrate the pin hole and the clamping hole. At this time, the use position of the counterweight block is fixed, but the cabinet door has an unlimited position structure. When an external object touches the cabinet door and rotates in the reverse direction to reset, the winding wheel will rotate in the reverse direction to unwind the wire rope. The loose wire rope can easily detach from the winding wheel and the reversing wheel, resulting in the inability to continue the resetting work. This brings hidden dangers to the continued use of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a switch cabinet reset component, which has the following beneficial effects:

[0018] (1) The utility model adopts a tensioning wheel. When the switch cabinet reset component is actually used, two sets of first sealed bearings are used. The operator rotates the cabinet door by hand, which will drive the winding wheel to reel in the wire rope through the rotating shaft. The wire rope will pull the counterweight block up. When the counterweight block moves up to the appropriate position, it is fixed. After the fixation is completed, the threaded through hole and the thread of the fastening bolt cooperate with each other. The operator rotates the fastening bolt counterclockwise by hand. When the fastening bolt is separated from the T-shaped slider, the telescopic spring is acted upon by its own elastic force and pushes the T-shaped slider. The T-shaped slider tightens the wire rope through the two sets of tensioning wheels. When an external object touches the cabinet door and rotates in the opposite direction, the telescopic spring continues to be acted upon by its own elastic force and pushes the T-shaped slider. The T-shaped slider continues to tighten the wire rope through the two sets of tensioning wheels to prevent the wire rope from slackening and detaching from the winding wheel and the reversing wheel. When use is completed, the counterweight block is removed. The counterweight block will slide downward along the L-shaped inner cavity under the action of gravity. During this process, the counterweight block will pull one end of the wire rope, and the wire rope will drive the take-up wheel to rotate in the opposite direction. The take-up wheel will drive the cabinet door to rotate in the opposite direction and reset through the rotating shaft. At the same time, the wire rope will drive the two sets of tensioning wheels to move forward and reset, and the T-shaped slider will squeeze the telescopic spring, waiting for the next use. The operator will rotate the fastening bolt clockwise by hand. When the fastening bolt contacts the T-shaped slider, the operation will be stopped. The two sets of mounting tubes and two sets of second sealed bearings make it possible for the two sets of tensioning wheels to rotate and use, avoiding the two sets of tensioning wheels from affecting the movement of the wire rope. The elastic force of the telescopic spring is limited, and it can only tighten the wire rope, but cannot drive the take-up wheel to rotate. The set tensioning wheel can avoid accidental unwinding of the wire rope, which may cause the wire rope to loosen and detach from the take-up wheel and the reversing wheel, thereby ensuring the continuous use of the reset component of the switch cabinet.

[0019] (2) The utility model adopts a brake pad. According to the above operation, before rotating the cabinet door, the operator moves the T-bar to the left by hand, driving the brake pad to squeeze the elastic spring. At the same time, the T-bar will stretch the telescopic hose. When the brake pad is separated from the counterweight, the cabinet door can be rotated. The cabinet door drives the winding wheel to reel in the wire rope through the rotating shaft. The wire rope will pull the counterweight upward. When the counterweight moves to the appropriate position, the operator releases the T-bar. The elastic spring is acted upon by its own elastic force to push the brake pad to move right and reset. When the brake pad contacts the counterweight, the friction between the brake pad and the counterweight is used to fix the use position of the counterweight. By setting the brake pad, the maximum rotation angle of the cabinet door can be controlled according to the use requirements. At the same time, it can prevent impurities or water vapor from entering the L-shaped inner cavity through the hole structure, thereby improving the practicality of the switch cabinet reset component.

[0036] In one embodiment, the two sets of first sealed bearings 3 are located on the same vertical line to avoid the rotating shaft 4 being unable to rotate horizontally due to the misalignment of the two sets of first sealed bearings 3 .

[0037] Working principle:

[0038] When the switch cabinet reset assembly is actually used, the two sets of first sealed bearings 3 are used, and the operator rotates the cabinet door 5 by hand, which will drive the winding wheel 7 to wind up the wire rope 8 through the rotating shaft 4. The wire rope 8 will pull the counterweight block 27 to move up. When the counterweight block 27 moves up to a suitable position, it is fixed. After the fixation is completed, the threaded through hole 19 and the thread of the fastening bolt 20 cooperate with each other, and the operator rotates the fastening bolt 20 counterclockwise by hand. When the fastening bolt 20 is separated from the T-shaped slider 15, the telescopic spring 21 is acted upon by its own elastic force and pushes the T-shaped slider 15. The T-shaped slider 15 tightens the wire rope 8 through the two sets of tensioning wheels 13. When the foreign object touches the cabinet door 5 and rotates in the opposite direction, the telescopic spring 21 continues to be acted upon by its own elastic force. When the wire rope 8 is used, it will push the T-shaped slider 15, and the T-shaped slider 15 will continue to tighten the wire rope 8 through the two sets of tensioning wheels 13 to prevent the wire rope 8 from slackening and separating from the winding wheel 7 and the reversing wheel 10. When use is completed, the counterweight block 27 is removed. The counterweight block 27 will slide downward along the L-shaped inner cavity 6 under the action of gravity. During this process, the counterweight block 27 will pull one end of the wire rope 8, and the wire rope 8 will drive the winding wheel 7 to rotate in the opposite direction. The winding wheel 7 drives the cabinet door 5 to rotate in the opposite direction and reset through the rotating shaft 4. At the same time, the wire rope 8 will drive the two sets of tensioning wheels 13 to move forward and reset, and the T-shaped slider 15 will squeeze the telescopic spring 21, waiting for the next use. The operator will rotate the fastening bolt 20 clockwise by hand. When the fastening bolt 20 is connected with the T-shaped slider 15 When the wire rope 8 is touched, the operation is stopped. The two sets of mounting tubes 16 and the two sets of second sealed bearings 17 make it possible to use the two sets of tension wheels 13 in rotation, so as to avoid the two sets of tension wheels 13 affecting the movement of the wire rope 8. The elastic force of the telescopic spring 21 is limited, so it can only tighten the wire rope 8, but cannot drive the winding wheel 7 to rotate. The set tension wheel 13 can avoid the wire rope 8 from loosening and detaching from the winding wheel 7 and the reversing wheel 10 when the wire rope 8 is accidentally unwound, so as to ensure the continuous use of the reset component of the switch cabinet. At the same time, according to the above operation, before rotating the cabinet door 5, the operator moves the T-bar 23 to the left by hand, driving the brake pad 12 to squeeze the elastic spring 24. At the same time, the T-bar 23 will stretch the telescopic hose 25. When the brake When the brake pad 12 is separated from the counterweight 27, the cabinet door 5 can be rotated, and the cabinet door 5 drives the winding wheel 7 to reel in the wire rope 8 through the rotating shaft 4. The wire rope 8 will pull the counterweight 27 upward. When the counterweight 27 moves to a suitable position, the operator releases the T-bar 23, and the elastic spring 24, under the action of its own elastic force, can push the brake pad 12 to move right and reset. When the brake pad 12 contacts the counterweight 27, the friction between the brake pad 12 and the counterweight 27 is utilized to fix the use position of the counterweight 27. Through the set brake pad 12, the maximum rotation angle of the cabinet door 5 can be controlled according to the use requirements, and at the same time, impurities or water vapor can be prevented from entering the L-shaped inner cavity 6 through the hole structure, thereby improving the practicality of the switch cabinet reset component.
