Description

Technical Field

[0001] The present invention relates to the technical field of electric power engineering, and particularly to a fixed support frame for a live arc extinguishing switch. Background Art

[0002] An arc extinguishing switch is a switching device used to extinguish electric arcs, mainly applied in medium- and high-voltage power systems to protect the safe operation of equipment and the power grid. Its working principle is to quickly cut off the electric arc in the circuit to prevent equipment damage and power grid faults caused by the electric arc. The arc extinguishing switch usually uses air as the insulating medium and has the characteristics of simple structure, low cost, and easy maintenance.

[0003] When the arc extinguishing switch performs arc extinguishing operations on the cable lines erected on utility poles, its top is usually fixedly hung on the cable, and power operation personnel operate it through an insulating operating rod. Since there is no limiting mechanism below the arc extinguishing switch, the arc extinguishing switch will swing around under the pull of the insulating operating rod. When used during live working, it affects the stability of the operation, reduces the safety of the operation personnel, and is prone to damage to the line. Therefore, a fixed support frame for a live arc extinguishing switch is needed to stably support the arc extinguishing switch installed on the line during live working. Summary of the Invention

Specific implementation manner

[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] Embodiment 1

[0034] Please refer to Figures 1 to 3 As shown, the present invention provides a fixed support frame for a live arc extinguishing switch, including a support frame body 1. The support frame body 1 includes a clamping mechanism 2 pre-set on the arc extinguishing switch, a vertical rod 3, and a telescopic mechanism 4 arranged below the vertical rod 3;

[0035] The telescopic mechanism 4 includes a sleeve 41. Adjusting bolts 12 are threadedly connected to both the upper and lower sides of the sleeve 41. A groove 13 is formed on the surface of the fixed cylinder 42. The inner wall of the groove 13 is provided with threads adapted to the adjusting bolts 12. A plurality of grooves 13 are provided and evenly distributed on the surface of the fixed cylinder 42. The threaded end of the adjusting bolt 12 penetrates through the sleeve 41 and extends into the interior of the groove 13 for fixing the sleeve 41 and the fixed cylinder 42;

[0036] A fixed cylinder 42 is slidably arranged inside the sleeve 41, and an extension rod 43 is slidably connected to the inner wall of the fixed cylinder 42 through a slider;

[0037] Among them, the vertical rod 3, the sleeve 41, the fixed cylinder 42, and the extension rod 43 are all made of PVC energy-saving materials, which not only reduces the production cost but also reduces the weight of the support frame;

[0038] On one side of the inner wall of the fixed cylinder 42, a small motor 9 is fixedly connected. A storage battery is arranged behind the small motor 9 for supplying power to the small motor 9. The output end of the small motor 9 is fixedly connected with a hollow threaded rod 10 through a coupling. The hollow setting can reduce the weight of the device. One end of the extension rod 43 is provided with an internal thread groove 11 adapted to the hollow threaded rod 10, and the extension rod 43 is threadedly sleeved on the hollow threaded rod 10;

[0039] The top end of the vertical rod 3 is fixedly connected with a fixed block 7. One side of the clamping mechanism 2 is fixedly connected with a rectangular frame 8 through a connecting rod. A cavity adapted to the fixed block 7 is arranged at the bottom of the rectangular frame 8, and the fixed block 7 penetrates into the interior of the rectangular frame 8 for connecting the vertical rod 3 and the clamping mechanism 2.

[0040] Through the setting of the above structure, when installing the vertical rod 3 and the clamping mechanism 2, according to the position of the clamping mechanism 2, rotate the hoop body 141 on the electric pole to adjust the position of the telescopic mechanism 4. By starting the small motor 9, drive the hollow threaded rod 10 to rotate. Under the sliding guidance of the slider, drive the extension rod 43 to move on the hollow threaded rod 10. The extension rod 43 moves out of the fixed cylinder 42, thereby driving the vertical rod 3 to move accordingly. After the vertical rod 3 moves below the rectangular frame 8, by moving the hoop body 141 upward, drive the fixed block 7 on the vertical rod 3 to enter the rectangular frame 8 and connect with the clamping mechanism 2 to connect the support frame together;

[0041] Among them, when the position of the arc extinguishing switch is relatively far, the fixed cylinder 42 of the telescopic mechanism 4 can be moved out of the sleeve 41 by screwing out the adjusting bolt 12 from the groove 13 on the fixed cylinder 42 in advance, so as to further expand the telescopic distance;

[0042] By pre-fixing the clamping mechanism on the arc extinguishing switch and cooperating with the setting of the telescopic mechanism, it can drive the vertical rod to automatically displace according to the installation position of the arc extinguishing switch on the line, so that the vertical rod is connected with the clamping mechanism. The device has a wider application range, is simple and fast to install, and can fix and support the arc extinguishing switch without the aid of external tools. When working at high altitude with electricity, the insulating operating rod operates on the arc extinguishing switch with a stable position, so that the arc extinguishing switch will not shake around, improving the stability of the operation, ensuring personal safety, and not easily pulling on the line, reducing the damage to the line.

[0043] Embodiment Two

[0044] On the basis of Embodiment One, please refer to Figure 1 and Figure 2As shown in the figure, the support frame body 1 further includes a fixing mechanism 14. The fixing mechanism 14 includes a hoop body 141, which is formed by hinging two arc-shaped plates. Threaded sleeves are fixedly connected to the periphery of the outer surface of the hoop body 141. A screw rod 142 is threadedly penetrated through the inner wall of each threaded sleeve. One end of the screw rod 142 penetrating into the interior of the hoop body 141 is fixedly connected to a fixing plate 143, and an anti-slip pad 144 is adhered to the inner side of the fixing plate 143. The anti-slip pad 144 increases the friction with the telegraph pole and improves the stability of installation. The opening of the hoop body 141 and the connection between the fixing mechanism 14 and the telescopic mechanism 4 are both clamped through the installation components.

[0045] Through the setting of the above structure, the operator wraps the hoop body 141 around the telegraph pole. After the hoop body 141 is fixed through the installation components, then according to the first embodiment, after connecting the fixed block 7 with the clamping mechanism 2, and then rotating the screw rod 142 forward and backward, the four inner fixing plates 143 can be driven to move back and forth, so that the hoop body 141 can be fixed on telegraph poles with different diameters, and finally the stable support of the arc suppression switch is completed.

[0046] Embodiment 3

[0047] Combining Embodiment 1 and Embodiment 2, please refer to Figure 1 、 Figure 2 and Figures 6 to 8 As shown in the figure, one end of the extension rod 43 penetrating outside the fixed cylinder 42 is fixedly connected to a threaded head 5. A hole adapted to the threaded head 5 is opened on the lower side of the vertical rod 3. The vertical rod 3 is sleeved on the threaded head 5. A fixing ring 6 for limiting the vertical rod 3 is threadedly arranged on the surface of the threaded head 5. The inner wall of the fixing ring 6 is provided with an internal thread adapted to the threaded head 5;

[0048] The installation component includes a cylinder body 15. Convex shells 16 are fixedly arranged on both the upper and lower sides of the cylinder body 15. A movable plate 17 is slidably arranged between the two sides of the inner wall of the convex shell 16. A clamping rod 18 is fixedly connected to the bottom of the movable plate 17. The bottom end of the clamping rod 18 penetrates through the cylinder body 15 and extends into the interior of the sleeve rod 21. A pull rod 19 penetrating outside the convex shell 16 is fixedly connected to the top of the movable plate 17. First springs 20 are fixedly connected to both sides of the top of the movable plate 17 and located on both sides of the pull rod 19. A sleeve rod 21 is arranged inside the cylinder body 15. The sleeve rod 21 is arranged opposite to the cylinder body 15 and is fixed at their connection points. Through holes 22 adapted to the clamping rod 18 are opened on the surfaces of the cylinder body 15 and the sleeve rod 21 to facilitate the clamping rod 18 to pass through.

[0049] With the above structure set, after the two ends of the hoop body 141 are merged, the sleeve rod 21 enters the cylinder body 15. Under the elastic force of the first spring 20, the movable plate 17 drives the clamping rod 18 to pass through the cylinder body 15 and the sleeve rod 21 downward in sequence, thereby fixing the two ends of the hoop body 141. Conversely, pulling the pull rod 19 upward drives the clamping rod 18 to move out of the cylinder body 15, and the hoop body 141 can be removed from the electric pole. Similarly, the telescopic mechanism 4 and the hoop body 141 can be disassembled through the installation component;

[0050] By rotating the fixed ring 6 out of the threaded head 5, the vertical rod 3 can be removed from the threaded head 5, and the vertical rod 3 drives the fixed block 7 to move downward out of the rectangular frame 8, and then it can be separated from the clamping mechanism 2. After the clamping mechanism 2 removes the arc extinguishing switch, it can be disassembled. Each part of the support frame body 1 can be disassembled, which helps to reduce its volume, is convenient for carrying and transportation, and no special tools are required for installation, and it can be assembled manually. The installation during high-altitude operation is more convenient and safe, and at the same time, it is convenient for the operators to quickly disassemble and take away the support frame after completing the work.

[0051] Embodiment 4

[0052] Combined with Embodiments 1 to 3, please refer to Figure 1 、 Figure 4 and Figure 5 As shown, the clamping mechanism 2 includes an adjustment component and two clamping plates 201. Insulating pads 202 are arranged on the inner sides of the two clamping plates 201. The insulating pads 202 are made of rubber material. Support plates 203 are fixedly connected to the opposite sides of the two clamping plates 201. The clamping part of the clamping plate 201 is set in a V shape, which can clamp arc extinguishing switches of different sizes and has a wider application range;

[0053] The adjustment component includes an adjustment seat 23. One side of the support plate 203 is slidably connected to the inner wall of the adjustment seat 23. Two movable shells 24 fixed to the top of the support plate 203 are slidably connected to the top of the adjustment seat 23. A second spring 25 is fixedly connected to one side of the inner wall of the movable shell 24. A push plate 26 is slidably arranged inside the movable shell 24. The upper part of the push plate 26 penetrates to the outside of the movable shell 24, and an activity groove adapted to the movable shell 24 is opened at the top of the movable shell 24. A plug rod 27 penetrating to the outside of the movable shell 24 is fixedly connected to one side of the push plate 26. A convex plate 28 is fixedly connected to the top of the adjustment seat 23, and a jack 29 adapted to the plug rod 27 is opened on the surface of the convex plate 28. A plurality of jacks 29 are opened, and the distance between the jacks 29 can be set according to the diameter difference of the arc extinguishing switches.

[0054] With the above structure, the operator pulls the push plate 26, and the push plate 26 drives the insertion rod 27 to squeeze the second spring 25, driving the insertion rod 27 out of the convex plate 28, so as to drive the movable housing 24 to move on the adjusting seat 23. The movable housing 24 drives the clamping plate 201 on the support plate 203 to move accordingly, adjusting the distance between the two clamping plates 201, and fixing the arc extinguishing switches of different sizes. The operator pre-installs the clamping mechanism 2 and the arc extinguishing switch on the ground, and then installs the arc extinguishing switch on the cable line. When performing live work at a high place, only a simple installation operation needs to be carried out at the hoop, and the installation of the entire support frame can be quickly completed, reducing the risk of working at a high place.

[0055] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited. Conventional equipment adapted to the equipment can be used.
