Description

Technical Field

[0001] The present invention relates to the technical field of high and low voltage power distribution equipment, and specifically to a switch cabinet with a leakage emergency protection function. Background Art

[0002] The switch cabinet is responsible for controlling and protecting the opening and closing of the circuit, similar to the "goalkeeper" of the power system. Its main task is to ensure the safe operation of the circuit, usually used for the control and management of the power system, mainly for the control and management of the power system to ensure the safe operation of the circuit, applicable to places where frequent switching operations are required. At present, the internal lines of the switch cabinet are complex, and leakage often occurs, with relatively high potential safety hazards. Although it is possible to prevent leakage by installing a grounding device inside the high and low voltage switch cabinet on the market now, it is not convenient to prevent leakage of the high and low voltage switch cabinet body itself, and there are still certain potential safety hazards.

[0003] An existing high and low voltage power distribution equipment with leakage prevention, with the authorization publication number CN221239965U, includes a high and low voltage power distribution cabinet. Two leakage prevention mechanisms are symmetrically installed on the high and low voltage power distribution cabinet. The leakage prevention mechanism includes a conductive block, a conductive grounding rod, a conductive plate, a measuring ring, a signal processor, an alarm lamp, and an insulating cover. The conductive block is installed inside the high and low voltage power distribution cabinet through a positioning component. The conductive plate is arranged between the conductive grounding rod and the side wall of the high and low voltage power distribution cabinet. The measuring ring is sleeved on the conductive grounding rod, and the output end of the signal processor is connected to the measuring ring. The alarm lamp is arranged on one side of the signal processor, and the alarm lamp is electrically connected to the signal processor. The insulating cover is detachably arranged on one side of the high and low voltage power distribution cabinet for protecting the conductive grounding rod. Through the above technical solution, the problem of inconvenient leakage prevention of the switch cabinet body itself in the prior art is solved.

[0004] The above existing solution has the following problems: When the switch cabinet is used in a harsh environment, the conductive grounding rod will lose its conductive function due to long-term environmental corrosion.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-10 , the present invention provides the first embodiment:

[0034] Refer toFigure 1 , a switch cabinet with a leakage emergency protection function, includes a cabinet body 1, an insulating cover 2 arranged on one side of the cabinet body 1, and a conductive grounding rod 3 connected to the internal conductive block of the cabinet body 1. The conductive grounding rod 3 includes a bent rod 301, a conductive grounding rod main body 302, and a grounding bus end 303. The conductive grounding rod main body 302 is separably arranged between the bent rod 301 and the grounding bus end 303, and the grounding bus end 303 is used to guide the current to the grounding grid. The above are all prior arts, so no more elaboration will be made;

[0035] Refer to Figure 2 、 5 , it further includes an annular base 4 fixedly arranged inside the insulating cover 2. There is a connecting plate 5 in the insulating cover 2 for fixing the annular base 4. An annular base 6 is rotatably arranged at the bottom of the annular base 4. A plurality of groups of enlarged holes 7 for the conductive grounding rod 3 to pass through are arranged along the circumferential side of the annular base 4. The aperture of the enlarged hole 7 is larger than the radial dimension of the conductive grounding rod main body 302 to prevent the annular base 6 from contacting the conductive grounding rod main body 302. A group of conductive grounding rod main bodies 302 are arranged at each position of the enlarged hole 7 on the annular base 4. Positioning devices 9 for positioning the conductive grounding rod main bodies 302 are symmetrically arranged on both sides of each enlarged hole 7 on the annular base 4. A notch area 8 is arranged at the position between the bent rod 301 and the grounding bus end 303 on the annular base 4. An isolation and cleaning chamber 10 is arranged inside the annular base 4. Cleaning brushes 11 are arranged along the circumferential side on the inner wall of the isolation and cleaning chamber 10. The brush is a strip-shaped fabric structure covering the isolation and cleaning chamber 10 or other materials for cleaning the conductive grounding rod 3. Import ends and export ends are arranged on both sides of the notch area 8 of the annular base 4. Isolation doors 12 are rotatably arranged at the import ends and the export ends. When the isolation doors 12 are opened, the notch area 8 is connected to the isolation and cleaning chamber 10. The rotation of the annular base 4 can replace the conductive grounding rod main body 302 between the bent rod 301 and the grounding bus end 303 and transfer the replaced conductive grounding rod main body 302 to the isolation and cleaning chamber 10 for isolation and cleaning. After the conductive grounding rod main body is used for a certain period, by driving the rotation of the annular base 6, a group of conductive grounding rod main bodies 302 in the isolation and cleaning chamber 10 can replace the conductive grounding rod main body 8 in the notch area 8 that is in use, and drive the replaced conductive grounding rod main body 302 into the isolation and cleaning chamber 10 for cleaning and protection. It should be noted that: the isolation doors 12 are rotatably arranged at the import ends and the export ends, and torsion springs are arranged at the rotation connection positions of the isolation doors 12 and the annular base 4. After a group of conductive grounding rod main bodies 302 are transported out to the notch area 8 or the conductive grounding rod main body 302 in the notch area 8 is transported into the isolation and cleaning chamber 10, the isolation doors 12 will automatically close under the action of the torsion springs.

[0036] Refer to Figure 3 、 9, the conductive grounding rod body 302 includes an upper rod body 3021 and a lower rod body 3022. Positioning rings 13 are provided on the circumferential outer walls of the upper rod body 3021 and the lower rod body 3022. The positioning device 9 includes a substrate 91 and positioning components 92 symmetrically arranged on the upper and lower sides of the substrate 91. The positioning component 92 includes a positioning roller 921 and an extension plate 922. One end of the extension plate 922 is connected to the substrate 91, and the other end extends toward the side of the conductive grounding rod body 302. A base rod 923 is connected to the side of the extension plate 922 away from the substrate 91. The base rods 923 are symmetrically arranged on both sides of the extension plate 922. The positioning rollers 921 are symmetrically arranged up and down on the upper and lower sides of each group of base rods 923. The end faces of the upper and lower groups of positioning rollers 921 close to each other respectively fit on the upper and lower side end faces of the positioning ring 13. Among them, the positioning roller 921 is an insulating roller shaft and will not affect the normal conduction of the conductive grounding rod body 302. Among them, one group of positioning rings 13 in the upper rod body 3021 or the lower rod body 3022 are all supported and positioned by eight groups of positioning rollers 921. The outer wall of the positioning roller 921 can contact the outer wall of the conductive grounding rod body 302 to realize more stable support and positioning of the conductive grounding rod 3.

[0037] Refer to Figure 3 , 5, 8, 9, in order to avoid the wear of the contact end caused by the horizontal movement of the conductive grounding rod main body 302 to replace the currently used conductive grounding rod main body 302, the upper rod body 3021 and the lower rod body 3022 are slidably spliced. A sliding groove 14 is provided on one side of the substrate 91 close to the conductive grounding rod main body. One end of the extension plate 922 extends into the sliding groove 14. A driving component 15 for driving the upper and lower groups of extension plates 922 to slide towards the side close to each other or away from each other is provided in the substrate 91. When the conductive grounding rod main body 302 in the working state is removed, the upper rod body 3021 and the lower rod body 3022 are slid towards the side close to each other, so that the upper rod body 3021 is separated from the bent rod 301 and the lower rod body 3022 is separated from the grounding busbar end 303, and then the conductive grounding rod main body 302 is removed, which can avoid the wear of the contact positions at the upper and lower ends and affect the subsequent use. When a new group of conductive grounding rod main bodies 302 move between the bent rod 301 and the grounding busbar end 303, the upper rod body 3021 and the lower rod body 3022 are then moved towards the side away from each other and docked with the upper and lower ends. The driving component 15 includes a driving rod 151, a driving gear disk 152, a driving motor 153 and a driving gear ring 154. The driving rod 151 is rotatably arranged in the sliding groove 14 and penetrates through the upper and lower groups of extension plates 922. First reciprocating spiral grooves 16 are provided on the circumferential outer walls on the upper and lower sides of the driving rod 151. The extension plate 922 is provided with a plate hole for the driving rod 151 to pass through, and a first guide block 17 slidably matched with the first reciprocating spiral groove 16 is arranged in the plate hole. The bottom of the driving rod 151 penetrates through the annular base 4, and a linkage gear disk 18 is fixed to the bottom end of the driving rod 151. The driving gear ring 154 is rotatably arranged at the bottom of the annular base 4, and the tooth part on the inner circumference of the driving gear ring 154 is meshed and connected with the linkage gear disks 18 at the bottoms of all the driving rods 151. The driving motor 153 is fixed on the annular base 6. A hidden groove for the motor to be hidden is provided on the annular base 6 to avoid the motor protruding above the annular base 6. The output end of the driving motor 153 extends to the lower end of the annular base 4 and is fixedly connected with the driving gear disk 152. The driving gear disk 152 is meshed and connected with the driving gear ring 154. By driving the driving gear disk 152 to rotate through the driving motor 153, the driving gear ring 154 can be driven to rotate, thereby driving each group of linkage gear disks 18 to rotate, driving the driving rod 151 to rotate, and driving the extension plate 922 to move up and down through the cooperation of the first guide block 17 and the first reciprocating spiral groove 16.

[0038] Refer to Figure 5 , 9, 10. In order to drive the driving gear disk 152 to rotate forward and backward by the driving motor 153 to realize the rotation of the annular base 6 and the up and down movement of the driving extension plate 922, an internal gear ring 19 is also coaxially provided at the bottom of the annular base 4. The internal gear ring 19 is rotatably arranged at the bottom of the annular base 4. The tooth part on the circumferential outer wall of the internal gear ring 19 is meshed and connected with the driving gear disk 152. A first one-way bearing 20 is connected between the internal gear ring 19 and the annular base 4. The internal gear ring 19 is rotatably arranged at the bottom of the annular base 4 through the first one-way bearing 20. An outer bearing 21 is connected between the driving gear ring 154 and the bottom of the annular base 4. The driving gear ring 154 is rotatably arranged at the bottom of the annular base 4 through the outer bearing 21. A second one-way bearing 22 is provided between the annular base 6 and the annular base 4. The annular base 6 is rotatably arranged at the bottom of the annular base 4 through the second one-way bearing 22. Among them, the direction in which the first one-way bearing 20 allows the internal gear ring 19 to rotate is the same as the direction in which the second one-way bearing 22 allows the annular base 6 to rotate (both can only rotate clockwise). When the driving gear disk 152 rotates clockwise, since the internal gear ring 19 cannot rotate counterclockwise, the motor and the annular base 6 will rotate clockwise. In addition, the annular base 6 is in interference fit with the bottom of the annular base 4, and the internal gear ring 19 is also in interference fit with the bottom of the annular base 4. And the force required to drive the annular base 6 to rotate is greater than the force required to drive the internal gear ring 19 and the driving gear ring 154 to rotate at the same time. When the driving gear disk 152 rotates counterclockwise, the annular base 6 will not rotate, the internal gear ring 19 will rotate clockwise, and the driving gear ring 154 will rotate counterclockwise. The counterclockwise rotation of the driving gear ring 154 will drive the linkage gear disk 18 to rotate, so that the up and down movement of the extension plate 922 can be driven by the driving rod 151. It should be noted that: in order to prevent the extension plate 922 from moving up and down when the driving gear ring 154 rotates clockwise and drives the linkage gear disk 18 to rotate, a third one-way bearing 23 is connected between the driving rod 151 and the linkage gear disk 18. When the driving gear ring 154 rotates clockwise and drives the linkage gear disk 18 to rotate counterclockwise, the linkage gear disk 18 cannot drive the driving rod 151 to rotate under the action of the third one-way bearing 23, so that the extension plate 922 cannot be driven to move up and down. When the driving gear ring 154 rotates counterclockwise and drives the linkage gear disk 18 to rotate counterclockwise, the driving rod 151 will follow the linkage gear disk 18 to rotate, so as to drive the extension plate 922 to move up and down.

[0039] Refer to Figure 5-7 , the isolation and cleaning chamber 10 penetrates through the bottom of the annular base 4. An annular limiting groove 24 is provided on the bottom inner wall of the isolation and cleaning chamber 10. An annular limiting plate 25 is provided on the circumferential outer wall of the annular base 6. The annular limiting plate 25 is rotatably arranged in the annular limiting groove 24. The cooperation between the annular limiting plate 25 and the annular limiting groove 24 can improve the sealing performance of the isolation and cleaning chamber 10, so that the conductive grounding rod body 302 located in the isolation and cleaning chamber 10 can be better stored.

[0040] Refer to Figure 5-8 , on the inner side of the bottom opening of the isolation cleaning chamber 10 at the bottom end face of the annular base 6, there is a first annular groove 26. At the top of the internal gear ring 19, there is a first annular ring 27. The first annular ring 27 extends into the first annular groove 26. The first one-way bearing 20 is sleeved and fixed on the circumferential outer wall of the first annular ring 27, and the outer wall is fixed on the inner wall of the first annular groove 26. On the outer side of the bottom opening of the isolation cleaning chamber 10 at the bottom end face of the annular base 6, there is a second annular groove 28. At the top of the driving gear ring 154, there is a second annular ring 29. The second annular ring 29 extends into the second annular groove 28. The outer bearing 21 is sleeved and fixed on the circumferential outer wall of the second annular ring 29, and the outer wall is fixed on the inner wall of the second annular groove 28. Above the annular limiting groove 24 in the isolation cleaning chamber 10, there is a third annular groove 30. The outer ring of the second one-way bearing 22 is embedded in the inner wall of the third annular groove 30, and the inner ring is sleeved and fixed on the circumferential outer wall of the annular base 6.

[0041] Refer to Figure 3 、 4 、9, 10, the present invention provides a second embodiment:

[0042] The improvement of this embodiment is that when the upper rod body 3021 and the lower rod body 3022 slide relatively, they can rotate simultaneously, improving the cleaning effect of the upper rod body 3021 and the lower rod body 3022 in the isolation cleaning chamber 10. Specifically as follows:

[0043] Refer to Figure 3 、 4 , at the bottom of the upper rod body 3021, there is a sliding hole 31. At the top of the lower rod body 3022, there is a sliding rod 32 that forms a sliding connection with the sliding hole 31. In the sliding hole 31, there is a second spiral groove 33. On the sliding rod 32, there is a second guide block 34 that forms a sliding fit with the second spiral groove 33. On the substrate 91 corresponding to the side of each reaming hole 7, there is a linkage structure 35 for driving the upper rod body 3021 and the lower rod body 3022 to rotate synchronously. Through the cooperation of the second guide block 34 and the second spiral groove 33, when the upper rod body 3021 and the lower rod body 3022 slide relatively, they can rotate relatively, and the linkage structure 35 can make the upper rod body 3021 and the lower rod body 3022 rotate synchronously.

[0044] Refer to Figure 9 、 10, the linkage structure 35 includes a linkage rod 353, a first synchronizing gear 351 and a second synchronizing gear 352. A through hole 39 is provided through the middle of the base rod 923. The base rod 923 is sleeved on the linkage rod 353 through the through hole 39. A third guide block 36 is provided on the linkage rod 353. A spiral groove 37 for the third guide block 36 to slide is provided on the inner wall of the through hole 39. Among them, the spiral directions of the spiral grooves 37 in the upper rod body 3021 and the lower rod body 3022 are opposite. The base rod 923 is rotatably arranged on the extension plate 922. A fixing plate 38 for fixing the linkage rod 353 is provided on the base plate 91. The first synchronizing gear 351 is arranged at one end of the positioning roller 921 in the axial direction. The second synchronizing gear 352 is arranged at one end of the positioning ring 13 in the axial direction and is meshed with the first synchronizing gear 351. It should be noted that: in this application, only one linkage structure 35 is provided at the corresponding position of each group of conductive grounding rods 3. The base rods 923 outside the linkage structure 35 are all fixed on the extension plate 922 and the positioning rollers 921 are all rotatably arranged on the base rods 923. The base rods 923 at the position where the linkage structure 35 is provided are rotatably arranged on the extension plate 922 and the positioning rollers 921 are fixed on the base rods 923. When the upper and lower extension plates 922 move towards the relatively far or close side, the upper and lower base rods 923 at the corresponding position of the linkage structure 35 will rotate in the opposite direction. Also, through the cooperation of the first synchronizing gear 351 and the second synchronizing gear 352, the upper rod body 3021 and the lower rod body 3022 will be driven to rotate in the opposite direction synchronously. In this way, the upper rod body 3021 and the lower rod body 3022 located in the isolation and cleaning chamber 10 can rotate during the lifting process, so as to obtain better cleaning of the cleaning brush 11.

[0045] Refer to Figure 1-10 , when the device is in use, when the conductive grounding rod main body 302 needs to be replaced after a certain period of use, start the drive motor 153. The drive motor 153 starts and drives the drive gear disk 152 to rotate counterclockwise. The counterclockwise rotation of the drive gear disk 152 will drive the drive gear ring 154 to rotate counterclockwise. The counterclockwise rotation of the drive gear ring 154 will drive the linkage gear disk 18 to rotate counterclockwise, thereby driving the drive rod 151 to rotate. Under the cooperation of the first guide block 17 and the first reciprocating spiral groove 16, the upper and lower extension plates 922 will be driven to move towards the relatively close side, so that the upper rod body 3021 and the lower rod body 3022 move towards the relatively close side, separating the conductive grounding rod main body 302, the bent rod 301 and the grounding bus bar end 303 in the notch area 8. When the upper rod body 3021 and the lower rod body 3022 in the notch area 8 slide relative to each other, the upper rod body 3021 and the lower rod body 3022 located in the isolation and cleaning chamber 10 will also slide relative to each other. Under the cooperation of the third guide block 36 and the spiral groove 37, and the first synchronizing gear 351 and the second synchronizing gear 352, the upper rod body 3021 and the lower rod body 3022 will rotate during the relative sliding process, so as to obtain better cleaning of the cleaning brush 11.

[0046] After the conductive grounding rod body 302 in the notch area 8 is separated from the bent rod 301 and the grounding bus bar end 303, the driving motor 153 drives the driving gear disk 152 to rotate clockwise. Since the internal gear ring 19 cannot rotate counterclockwise, at this time, the clockwise rotation of the driving gear disk 152 will drive the annular base 6 to rotate clockwise. At this time, the driving gear ring 154 will follow the clockwise rotation. Under the action of the third one-way bearing 23, the driving gear ring 154 drives the linkage gear disk 18 to rotate without driving the driving rod 151 to rotate. The rotation of the annular base 6 will drive the conductive grounding rod body 302 in the notch area 8 to enter the isolation and cleaning chamber 10 from the inlet end of the annular base 4, and at the same time drive a group of conductive grounding rod bodies 302 in the isolation and cleaning chamber 10 to move from the outlet end to the notch area 8. Then, the driving motor 153 is driven to drive the driving gear disk 152 to rotate counterclockwise again. At this time, under the cooperation of the first guide block 17 and the first reciprocating spiral groove 16, the upper rod body 3021 and the lower rod body 3022 will be driven to move away from each other again and be respectively docked with the bent rod 301 and the grounding bus bar end 303. Each time the conductive grounding rod body 302 is docked in the notch area 8 or the conductive grounding rod body 302 in the notch area 8 is separated from the notch area 8, the upper rod body 3021 and the lower rod body 3022 in the isolation and cleaning chamber 10 will move and rotate and be cleaned once.
