Description

Technical Field

[0001] This invention relates to the field of equalizing ball technology, specifically to a valve hall equalizing ball with a discharge structure. Background Technology

[0002] An equipotential bonding ball is a ring-shaped steel ring installed on the top of an insulator bushing. It is widely used in the power industry. There are many types of equipotential bonding balls on the market, but they still have some shortcomings:

[0003] CN210722593U discloses an equalizing ball with a reinforced mounting section. This device has multiple fixing plates that can firmly fix the equalizing ball body, making the structure more stable. It also has a mounting base to facilitate the installation of the equalizing ball body. The structure is simple and practical. However, this device still has some shortcomings. During the fixing process, the outer side of the device is prone to deformation during connection. After long-term use, its surface may be damaged, thus failing to provide adequate protection. In addition, during use, the connection point may not discharge well and is prone to leakage.

[0004] Therefore, we proposed that a valve chamber equalizing ball with a discharge structure can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a valve hall equalizing ball with a discharge structure to solve the problems mentioned in the background art. Currently available equalizing balls on the market are prone to deformation on their outer side during the connection process, and their surface may be damaged after long-term use, thus failing to provide adequate protection. In addition, during use, the connection may not discharge properly, and leakage may easily occur.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a valve hall equalizing ball with a discharge structure, comprising an equalizing ball body, a load-bearing cover, a rotating ring, a support plate, and a through groove;

[0007] The equalizing ball body includes an equalizing upper plate and an equalizing lower plate. The load-bearing cover is disposed inside the equalizing ball body. A rotating ring is disposed on the inner side of the load-bearing cover. Support plates are disposed around the outer perimeter of the equalizing ball body.

[0008] Also includes:

[0009] The bottom end of the load-bearing cover is connected to a connecting spring. The load-bearing cover is located inside the rotating ring, and a limit block is provided on the outer side of the load-bearing cover. The other end of the limit block extends into the interior of the limit groove.

[0010] A support rod is provided on the outer side of the rotating ring, and the other end of the support rod is connected to the end of the connecting rod that extends into the body of the equalizing ball.

[0011] Preferably, the size of the equalizing upper plate is equal to that of the equalizing lower plate, and both the upper and lower plates have through slots on their outer sides. One end of the connecting rod is connected to the equalizing ball body via a spiral spring, which facilitates stable sliding of the connecting rod inside the equalizing ball body.

[0012] Preferably, the two ends of the support rod are movably connected to the outer side of the rotating ring and the connecting rod, respectively, and the end of the connecting rod extending out of the outer side of the equalizing ball body is integrally set with the support plate, thereby facilitating the opening of the support plate and preventing the device from deforming.

[0013] Preferably, both the upper and lower ends of the rotating ring are fixed with limiting blocks, and the rotating ring forms a rotating structure with the inner wall of the equalizing ball body through the limiting blocks, thereby facilitating the stable rotation of the rotating ring on the inner wall of the equalizing ball body through the limiting blocks.

[0014] Preferably, the limiting groove is obliquely formed on the inner side of the rotating ring, and the inner wall of the limiting groove and the inner wall of the limiting block form a clearance fit, which facilitates the movement of the limiting block inside the limiting groove.

[0015] Preferably, a discharge groove is provided on the inner side of the equalizing ball body, and a discharge rod is provided inside the discharge groove, thus facilitating the discharge treatment of the device.

[0016] Preferably, there are two sets of discharge rods symmetrically distributed about the center of the bottom end of the load-bearing cover, and the outer wall of the discharge rod is in contact with the discharge groove, thereby facilitating the sliding of the discharge rod inside the discharge groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The valve hall equalizing ball with discharge structure is arranged as follows:

[0018] (1) The valve hall equalizing ball with discharge structure is equipped with a load-bearing cover. During the process of the load-bearing cover moving inside the rotating ring, the load-bearing cover will drive the limiting block to move. Therefore, the limiting block moves inside the limiting groove opened on the inner side of the rotating block. During the rotation of the rotating block, the connecting rod will be driven to move through the support rod. The other end of the connecting rod will drive the support plate to extend to a certain extent. Through the above settings, it is convenient to provide certain protection for the device.

[0019] (2) The valve hall equalizing ball with discharge structure is equipped with a discharge rod. During the movement of the load-bearing cover, the load-bearing cover will move stably inside the through groove through the connecting spring. During the movement, the bottom inner side of the load-bearing cover will drive the discharge rod to move inside the discharge groove. During the movement, the two sets of discharge rods will dock. Therefore, through the above settings, it is convenient for stable discharge inside. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0027] Please see Figure 1-5This invention provides a technical solution: a valve hall equalizing ball with a discharge structure, comprising an equalizing ball body 1, a load-bearing cover 2, a rotating ring 4, a support plate 10, and a through groove 13; the equalizing ball body 1 includes an upper equalizing plate 101 and a lower equalizing plate 102, and the load-bearing cover 2 is disposed inside the equalizing ball body 1; the size of the upper equalizing plate 101 is equal to the size of the lower equalizing plate 102, and the outer sides of both the upper equalizing plate 101 and the lower equalizing plate 102 are provided with through grooves 13, one end of the connecting rod 8 is connected to the equalizing ball body 1 via a spiral spring 9; a rotating ring 4 is disposed inside the load-bearing cover 2, and a support plate 10 is disposed around the outer perimeter of the equalizing ball body 1; it also includes: a connecting spring 3 connected to the bottom end of the load-bearing cover 2, and the load-bearing cover 2 is disposed inside the valve hall equalizing ball body 1. A limiting block 5 is provided on the inner side of the rotating ring 4 and the outer side of the load-bearing cover 2, with the other end of the limiting block 5 extending into the interior of the limiting groove 6; a support rod 7 is provided on the outer side of the rotating ring 4; both the upper and lower ends of the edge of the rotating ring 4 are fixed with limiting blocks 401, and the rotating ring 4 forms a rotating structure with the inner wall of the equalizing ball body 1 through the limiting blocks 401; the other end of the support rod 7 is connected to the end of the connecting rod 8 that extends into the interior of the equalizing ball body 1; both ends of the support rod 7 are movably connected to the outer side of the rotating ring 4 and the connecting rod 8 respectively, and the end of the connecting rod 8 extending out of the outer side of the equalizing ball body 1 is integrally set with the support plate 10; the limiting groove 6 is obliquely opened on the inner side of the rotating ring 4, and the inner wall of the limiting groove 6 and the inner wall of the limiting block 5 form a clearance fit. (See attached...) Figure 1-5 First, by inserting one end of the insulator into the through groove 13 opened inside the upper and lower equalizing plates 101 and 102, the bottom end of the load-bearing cover 2 will be squeezed. As a result, the load-bearing cover 2 will drive the connecting spring 3 to store force, thus causing the load-bearing cover 2 to limit the block 5 inside the rotating ring 4. Since the outer side of the limit block 5 extends into the limit groove 6, when the limit block 5 rotates, the limit block 5 will drive the rotating ring 4 to rotate through the limit groove 6. The outer side of the rotating ring 4 is connected to the support rod 7, and the other end of the support rod 7 is movably connected to the inner end of the connecting rod 8, so that the connecting rod 8 will move to a certain extent inside the equalizing ball body 1. At the same time, the connecting rod 8 will drive the support plate 10 to extend to a certain extent. When the support plate 10 moves to a certain extent, it will provide a certain degree of protection for the device.

[0028] The inner side of the equalizing ball body 1 is provided with a discharge groove 11, and a discharge rod 12 is arranged inside the discharge groove 11; two sets of discharge rods 12 are symmetrically distributed about the center position of the bottom end of the load-bearing cover 2, and the outer wall of the discharge rod 12 is in contact with the discharge groove 11; combined with the attached Figure 1When the load-bearing cover 2 moves, and the bottom end of the load-bearing cover 2 moves through the connecting spring 3, the bottom end of the load-bearing cover 2 will drive the discharge rod 12 to move. Since the bottom end of the discharge rod 12 is set inside the discharge tank 11, the two sets of discharge rods 12 will dock. Through the above settings, it is convenient to perform a certain discharge treatment on the device.

[0029] Working principle: First, by inserting one end of the insulator into the through slot 13 opened inside the upper and lower equalizing plates 101 and 102, the bottom end of the load-bearing cover 2 will be squeezed. This causes the load-bearing cover 2 to drive the connecting spring 3 to store force, thus causing the load-bearing cover 2 to limit the block 5 inside the rotating ring 4. The limiting block 5 will drive the rotating ring 4 to rotate through the limiting slot 6. The outer side of the rotating ring 4 is connected to the support rod 7. At the same time, the connecting rod 8 will drive the support plate 10 to extend to a certain extent. When the support plate 10 moves to a certain extent, it will provide a certain degree of protection for the device. During the movement of the load-bearing cover 2, the bottom end of the load-bearing cover 2 will move through the connecting spring 3. The bottom end of the load-bearing cover 2 will drive the discharge rod 12 to move. Since the bottom end of the discharge rod 12 is set inside the discharge slot 11, the two sets of discharge rods 12 will dock. Through the above settings, it is convenient to perform a certain discharge treatment on the device.
