Description

Technical Field

[0001] The present invention relates to the technical field of valve hall grading balls, and specifically to a valve hall grading ball that can be quickly installed. Background Art

[0002] Grading balls are mainly used in electrical equipment. To ensure the balance and stability of voltage, grading balls need to be installed on insulators. For example, a test grading ball applicable to high altitude and high dry environments with the publication number CN208903757U includes a grading ball upper cover and a grading ball base. Grooves are provided at the top of the grading ball upper cover and the bottom of the grading ball base, and mounting holes are provided at the top of the grooves. Upper mounting plates are provided on the left and right sides of the inner side wall of the grading ball upper cover, and a lower mounting plate is provided at the top of the inner side wall of the grading ball base... A grading ball device with stable installation structure and good grading effect. However, the test grading ball applicable to high altitude and high dry environments still has the following disadvantages during actual use:

[0003] Traditional grading balls are not convenient enough to install. Since the end of the insulator needs to be installed inside the grading ball, operators need to reach inside the grading ball to install it, which increases the installation difficulty and cannot achieve quick and stable installation of the grading ball. In view of the above problems, there is an urgent need to innovate on the basis of the original valve hall grading balls. Summary of the Invention

[0004] The purpose of the present invention is to provide a valve hall grading ball that can be quickly installed, so as to solve the problems in the above background art that traditional grading balls are not convenient enough to install. Since the end of the insulator needs to be installed inside the grading ball, operators need to reach inside the grading ball to install it, which increases the installation difficulty and cannot achieve quick and stable installation of the grading ball.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A valve hall grading ball that can be quickly installed is provided with a grading ball. Fixing holes are provided at the top and bottom of the grading ball, and an insulator is installed through the fixing hole at the bottom. An installation plate is fixed on the side of the insulator, and an installation hole is reserved inside the installation plate;

[0006] It includes:

[0007] Support plates, fixed on the inner wall of the grading ball. Adjacent support plates are fixedly connected by a connecting frame, and an adjusting shaft is movably arranged at the top of the connecting frame. A traction rope is wound around the outside of the adjusting shaft, and the other end of the traction rope is wound around the outside of a movable cylinder;

[0008] Movable cylinder, movably installed on the upper end surface of the support plate. A limiting block is movably arranged inside the movable cylinder, and a locking rod is fixed on the lower end surface of the limiting block;

[0009] A gear is fixedly sleeved outside the movable cylinder. A rack is movably arranged on the side of the gear, and the end of the rack is fixedly connected to the movable rod. An activity groove is formed in the support plate on the outer side of the movable rod, and connecting plates are fixedly connected to both ends of the movable rod.

[0010] Preferably, the adjusting shaft and the connecting frame are in damping rotational connection, and 3 traction ropes are wound around the adjusting shaft. Moreover, the traction ropes, the movable cylinder and the support plate are all distributed at equal angles. By rotating the adjusting shaft, the 3 traction ropes can be wound up. Due to the damping rotation, the adjusting shaft can be ensured to remain stable after rotation.

[0011] Preferably, the movable cylinder and the support plate are in bearing connection, and the limiting block and the inner wall of the movable cylinder are in longitudinal sliding connection. The bottom of the locking rod threadedly penetrates through the support plate. After the traction rope is pulled and wound up, the movable cylinder can be driven to rotate on the support plate. During the rotation process, due to the threaded connection between the locking rod and the support plate, the locking rod can be driven to move downward through the limitation of the limiting block.

[0012] Preferably, the gear and the rack are in meshing connection, and the 3 gears rotate in the same direction. Moreover, the cross section of the rack is an "L" - shaped structure. When the movable cylinder rotates, the gears can be driven to rotate synchronously, and the rack can be driven to move through the threaded connection with the rack.

[0013] Preferably, the movable rod and the support plate form a sliding structure through the activity groove, and the movable rod and the support plate are perpendicularly arranged. Moreover, the support plate is located on the transverse axis of the pressure - equalizing ball. After the rack moves, the movable rod can be pushed to move synchronously in the activity groove, and the connecting plate can be driven to move.

[0014] Preferably, the connecting plates are symmetrically distributed about the transverse axis of the movable rod, and the cross section of the connecting plate is an arc - shaped structure. The moved connecting plate can be attached to the inner wall of the pressure - equalizing ball to play a supporting role.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For the pressure - equalizing ball of the valve hall that can be quickly installed, the operator does not need to put his hand into the pressure - equalizing ball to realize the installation between the pressure - equalizing ball and the insulator, which not only improves the installation efficiency and convenience of the pressure - equalizing ball, but also ensures the stability of the pressure - equalizing ball during use. The specific content is as follows:

[0016] 1. By rotating the adjusting shaft, the winding of three sections of traction ropes can be realized, thereby driving the movable cylinder to rotate on the support plate. After the adjusting shaft rotates to wind the traction ropes, it can maintain stability. When the movable cylinder rotates, through the threaded connection between the locking rod and the support plate, the locking rod can be driven to move downward and rotate. And through the sliding of the limiting block in the movable cylinder for limiting, the connection between the support plate and the mounting plate can be realized through the locking rod, so as to quickly install the grading ball on the top of the insulator.

[0017] 2. During the rotation of the movable cylinder, the gear can be driven to rotate synchronously, and the rack can be driven to move through meshing with the rack. In this way, the movable rod can be pushed to move synchronously in the movable groove, and the connecting plate can be driven to approach and fit against the inner wall of the grading ball, realizing the support of the connecting plate inside the grading ball and improving the overall strength of the grading ball.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] 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.

[0025] Please refer to Figures 1-5, the present invention provides a technical solution: a voltage equalizing sphere for valve hall that can be quickly installed, provided with a voltage equalizing sphere 1. Fixing holes 2 are opened at both the top and bottom of the voltage equalizing sphere 1, and an insulator 3 is installed through the fixing hole 2 at the bottom. An installation plate 4 is fixed to the side of the insulator 3, and an installation hole 5 is reserved inside the installation plate 4;

[0026] It includes: a support plate 6, fixed to the inner wall of the voltage equalizing sphere 1. Adjacent support plates 6 are fixedly connected by a connecting frame 7, and an adjusting shaft 8 is movably arranged at the top of the connecting frame 7. A traction rope 9 is wound around the outside of the adjusting shaft 8, and the other end of the traction rope 9 is wound around the outside of a movable cylinder 10; a movable cylinder 10, movably installed on the upper end face of the support plate 6. A limiting block 11 is movably arranged inside the movable cylinder 10, and a locking rod 12 is fixed to the lower end face of the limiting block 11; a gear 13, fixedly sleeved on the outside of the movable cylinder 10. A rack 14 is movably arranged on the side of the gear 13, and the end of the rack 14 is fixedly connected to a movable rod 15. A movable groove 16 is opened on the support plate 6 on the outside of the movable rod 15, and connecting plates 17 are fixedly connected to both ends of the movable rod 15.

[0027] As Figure 1 and Figures 3-4 shown, the adjusting shaft 8 and the connecting frame 7 are in a damped rotational connection, and 3 segments of traction ropes 9 are wound around the adjusting shaft 8. Moreover, the traction ropes 9, the movable cylinder 10, and the support plate 6 are all equally angularly distributed. By rotating the adjusting shaft 8, synchronous winding of the 3 segments of traction ropes 9 can be achieved. After rotation, the adjusting shaft 8 can ensure the stability of the position after rotation through damped rotation; the movable cylinder 10 and the support plate 6 are in a bearing connection, and the limiting block 11 and the inner wall of the movable cylinder 10 are in a longitudinal sliding connection. The bottom of the locking rod 12 threadedly penetrates through the support plate 6. When the traction rope 9 is pulled, it can drive the movable cylinder 10 to rotate on the support plate 6, and the 3 movable cylinders 10 can rotate synchronously in the same direction. Then, through the threaded connection between the locking rod 12 and the support plate 6, and the sliding of the limiting block 11 in the movable cylinder 10 for limiting, it can ensure that the locking rod 12 can move downward during rotation and pass through the installation hole 5 on the installation plate 4, realizing the stable connection between the installation plate 4 and the support plate 6, and there is no need to put hands into the voltage equalizing sphere 1, improving the convenience of installation;

[0028] As Figures 1-2 and Figure 5As shown, the gear 13 and the rack 14 are meshed and connected, and the rotation directions of the three gears 13 are the same. Moreover, the cross-section of the rack 14 is an "L"-shaped structure. When the movable cylinder 10 rotates, it can drive the gear 13 to rotate synchronously, and drive the rack 14 to move horizontally through the meshing with the rack 14; the movable rod 15 and the support plate 6 form a sliding structure through the movable groove 16, and the movable rod 15 and the support plate 6 are arranged perpendicular to each other. Moreover, the support plate 6 is located on the horizontal axis of the pressure equalizing ball 1. When the movable rod 15 moves, it can slide in the movable groove 16, and realize the synchronous movement of the movable rods 15 distributed at equal angles; the connecting plates 17 are symmetrically distributed about the horizontal axis of the movable rod 15, and the cross-section of the connecting plate 17 is an arc structure. When the movable rod 15 moves, it drives the connecting plates 17 to move synchronously and approach and fit against the inner wall of the pressure equalizing ball 1, supporting the inner wall of the pressure equalizing ball 1 and enhancing its strength.

[0029] Working principle: As Figures 1-5 shown, after the pressure equalizing ball 1 to be installed is sleeved on the top of the insulator 3, the three traction ropes 9 are wound by rotating the adjusting shaft 8, so that the movable cylinder 10 can be driven to rotate on the support plate 6. Through the limitation of the limiting block 11 and the threaded connection between the locking rod 12 and the support plate 6 in the initial state, the locking rod 12 can be rotated and moved downward, and then threadedly installed in the mounting hole 5 on the mounting plate 4, realizing the stable connection between the support plate 6 and the mounting plate 4, and further ensuring the stability of the installation between the pressure equalizing ball 1 and the insulator 3;

[0030] During the rotation of the movable cylinder 10, it can drive the gear 13 to rotate synchronously, and through the meshing with the rack 14, it can push the movable rod 15 and the connecting plates 17 to move synchronously, drive the connecting plates 17 to approach and fit against the inner wall of the pressure equalizing ball 1, and then support the inner wall of the pressure equalizing ball 1 to enhance the strength of the pressure equalizing ball 1 itself.
