Description

Technical Field

[0001] This utility model relates to the field of high-voltage disconnect switches for vehicle transportation, and more specifically, to an auxiliary device for installing high-voltage disconnect switches. Background Technology

[0002] During power system maintenance and repair, high-voltage disconnect switches reliably isolate the equipment under maintenance from energized parts, creating a clear disconnect point and ensuring the safety of maintenance personnel. For example, in a substation, when maintaining a transmission line or transformer, operating the disconnect switch can isolate it from other energized equipment, preventing accidental energization and resulting safety incidents. During power system operation, switching operations are frequently required to change the system's operating mode. High-voltage disconnect switches, used in conjunction with circuit breakers, enable circuit switching and conversion. For instance, in substation busbar switching operations, the disconnect switch connected to one busbar is first disconnected, and then the disconnect switch connected to another busbar is closed, thus achieving busbar switching and ensuring normal power supply to the power system.

[0003] During the installation of high-voltage disconnect switches, they need to be fixed and clamped. Before clamping, they need to be positioned in a designated location for installation. However, existing devices require manual adjustment for positioning, which can easily lead to inaccurate positioning and cause deviations in the clamped high-voltage disconnect switches.

[0004] Therefore, we have made improvements and proposed an auxiliary device for installing high-voltage disconnect switches. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing positioning devices require manual adjustment, which can easily lead to inaccurate positioning and cause deviations in the clamped high-voltage disconnect switch.

[0006] In order to achieve the above-mentioned objectives, this utility model provides an auxiliary device for installing high-voltage disconnect switches to solve the above problems.

[0007] The present invention is as follows:

[0008] The device includes a fixed plate, the upper surface of which is provided with a groove, and the groove is circular. The side wall of the groove is provided with a positioning groove. A rotating ring is rotatably connected to the bottom surface of the groove. A positioning block is fixedly connected to the upper surface of the rotating ring. The positioning block engages with the positioning groove. A connecting plate is fixedly connected to the inner wall of the rotating ring. A movable rod is fixedly connected to the connecting plate away from the surface of the rotating ring.

[0009] Preferably, the movable rod contracts upward from the lower end to a variable diameter shape, and the outer surface of the movable rod has a plurality of sliding grooves arranged in a ring, with a connecting rod slidably connected to the inner wall of the sliding groove.

[0010] Preferably, the connecting rod is fixedly connected to an extension rod away from the movable rod surface, and the extension rod is fixedly connected to a clamping plate away from the movable plate surface.

[0011] Preferably, a movable plate is hinged to the upper surface of the clamping plate, a limit spring is fixedly connected to the lower surface of the movable plate, and the other end is fixedly connected to the clamping plate. A limit plate is fixedly connected to the clamping plate away from the limit spring surface. The limit plate is U-shaped and its two sides are parallel to the movable plate.

[0012] Preferably, the upper surface of the fixed disk has a ring array of several slots and the connecting rod slides on its inner wall. The end of the slot away from the movable rod is fixedly connected to a support block, and the extension rod slides on the inner wall of the support block.

[0013] Preferably, a spring rod is fixedly connected to the lower end of the movable rod, a support frame is fixedly connected to the lower end of the spring rod, and a base is fixedly connected to the lower surface of the fixed plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. When positioning, place the high-voltage disconnect switch on the positioning block on the upper surface of the rotating disk, and then rotate the rotating ring. During the rotation, the positioning block on the upper surface of the rotating ring engages with the positioning groove. At this time, the rotating ring is locked and cannot rotate, and locking is achieved at the same time. In addition, when the high-voltage disconnect switch is placed, the rotating ring and the movable rod connected by the connecting plate slide down. The sliding of the movable rod can drive the clamping plate to slide and clamp the high-voltage disconnect switch.

[0016] 2. When the high-voltage disconnect switch presses against the movable rod, the movable rod slides downward. During the sliding process, the connecting rod that is slidably connected to it is pulled by the tension, which drives the connecting rod and the extension rod to slide. During the sliding process, the extension rod drives the clamping plate to slide and clamp the high-voltage disconnect switch. Attached Figure Description

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] As in the background art, existing positioning devices require manual adjustment, which can easily lead to inaccurate positioning and consequently cause deviations in the clamped high-voltage disconnect switch.

[0032] To solve this technical problem, this utility model provides an auxiliary device for installing high-voltage disconnect switches, which uses the gravity of the high-voltage disconnect switch itself to achieve the functions of clamping and positioning.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] A high-voltage disconnector installation auxiliary device includes a fixing plate 101. The upper surface of the fixing plate 101 is provided with a groove 102, which is circular. The side wall of the groove 102 is provided with a positioning groove 103. A rotating ring 104 is rotatably connected to the bottom surface of the groove 102. A positioning block 105 is fixedly connected to the upper surface of the rotating ring 104 and engages with the positioning groove 103. A connecting plate 106 is fixedly connected to the inner wall of the rotating ring 104. A movable rod 107 is fixedly connected to the connecting plate 106 away from the surface of the rotating ring 104.

[0037] During positioning, the high-voltage disconnect switch is placed on the positioning block 105 on the upper surface of the rotating disk. Then, the rotating ring 104 is rotated. During the rotation, the positioning block 105 on the upper surface of the rotating ring 104 engages with the positioning groove 103. At this time, the rotating ring 104 is locked and cannot rotate, and locking is achieved at the same time. In addition, when the high-voltage disconnect switch is placed, the rotating ring 104 and the movable rod 107 connected by the connecting plate 106 slide down. The sliding down of the movable rod 107 can drive the clamping plate 302 to slide and clamp the high-voltage disconnect switch.

[0038] The movable rod 107 contracts upwards from its lower end to a variable diameter shape. Several grooves 201 are arranged in a ring on the outer surface of the movable rod 107. A connecting rod 202 is slidably connected to the inner wall of each groove 201. An extension rod 301 is fixedly connected to the connecting rod 202 away from the movable rod 107. A clamping plate 302 is fixedly connected to the extension rod 301 away from the movable plate 401.

[0039] The movable rod 107 is configured to have a variable diameter so that the connecting rod 202 can slide during the lifting process. When the high-voltage disconnecting switch presses the movable rod 107, the movable rod 107 slides downward. During the sliding process, the connecting rod 202, which is slidably connected to it, is subjected to tension, which drives the connecting rod 202 and the extension rod 301 to slide. During the sliding process, the extension rod 301 drives the clamping plate 302 to slide and clamp the high-voltage disconnecting switch.

[0040] A movable plate 401 is hinged to the upper surface of the clamping plate 302. A limit spring 402 is fixedly connected to the lower surface of the movable plate 401, and the other end is fixedly connected to the clamping plate 302. A limit plate 403 is fixedly connected to the side of the clamping plate 302 away from the limit spring 402. The limit plate 403 is U-shaped and its two sides are parallel to the movable plate 401.

[0041] The movable plate 401 hinged to the upper surface of the clamping plate 302 can limit the high-voltage disconnecting switch. When limiting, the high-voltage disconnecting switch is squeezed by gravity and causes the movable plate 401 to flip. When the high-voltage disconnecting switch descends to directly below the movable plate 401, the limiting plate 403 fixedly connected to the clamping plate 302 away from the limiting spring 402 can restrict the movable plate 401 from flipping upward, thereby preventing the high-voltage disconnecting switch from detaching from the clamping mechanism. The clamping plate 302 fixedly connected to the extension rod 301 away from the movable plate 401 can clamp the high-voltage disconnecting switch.

[0042] The upper surface of the fixed plate 101 has a ring array of slots 501, and the connecting rod 202 slides on its inner wall. The end of the slot 501 away from the movable rod 107 is fixedly connected to the support block 502, and the extension rod 301 slides on the inner wall of the support block 502.

[0043] The fixed plate 101 has several slots 501 arranged in a ring array to allow the connecting rod 202 to slide and drive the extension rod 301 to slide on the inner wall of the support block 502, thereby realizing the sliding of the clamping plate 302. During the sliding process, the clamping plate 302 squeezes the high-voltage disconnecting switch.

[0044] A spring rod 601 is fixedly connected to the lower end of the movable rod 107, a support frame 602 is fixedly connected to the lower end of the spring rod 601, and a base 603 is fixedly connected to the lower surface of the fixed plate 101.

[0045] The spring rod 601 fixedly connected to the lower end of the movable rod 107 is used to control the rise of the movable rod 107. When clamping the high-voltage disconnect switch, the high-voltage disconnect switch presses down on the movable rod 107, thereby squeezing the spring rod 601. After clamping is completed, the high-voltage disconnect switch is removed, and the spring rod 601 loses the squeezing force and squeezes the movable rod 107 upward due to the elastic force. The rise of the movable rod 107 drives the rotating ring 104 to rise, thereby releasing it from fixation and rotatably connecting it to the inner wall of the groove 102. The support frame 602 fixedly connected to the lower end of the spring rod 601 is used to support the spring rod 601. The base 603 fixedly connected to the lower surface of the fixed plate 101 is used to support the clamping device.

[0046] The usage process of the high-voltage disconnector installation auxiliary device provided by this utility model is as follows:

[0047] During positioning, the high-voltage disconnect switch is placed on the positioning block 105 on the upper surface of the rotating disk. Then, the rotating ring 104 is rotated. During the rotation, the positioning block 105 on the upper surface of the rotating ring 104 engages with the positioning groove 103. At this time, the rotating ring 104 is locked and cannot rotate, and locking is achieved at the same time. In addition, when the high-voltage disconnect switch is placed, the rotating ring 104 and the movable rod 107 connected by the connecting plate 106 slide down. The sliding down of the movable rod 107 can drive the clamping plate 302 to slide and clamp the high-voltage disconnect switch.

[0048] When the high-voltage disconnect switch presses against the movable rod 107, the movable rod 107 slides downward. During the sliding process, the lower connecting rod 202, which is slidably connected to it, is pulled by the tension, causing the connecting rod 202 and the extension rod 301 to slide. During the sliding process, the extension rod 301 causes the clamping plate 302 to slide and clamp the high-voltage disconnect switch.
