Description

Technical Field

[0001] This utility model relates to the field of ring network box technology, specifically a ring network box that facilitates adjustment of the position of the reserved holes. Background Technology

[0002] As is well known, ring main units, also known as box-type switchgear, are widely used in daily life. They contain high-voltage power distribution equipment. In the entire urban power supply system, when there is an accident or a box-type transformer needs to be repaired, the left and right ring main incoming lines can be disconnected to isolate the accident point or the box-type transformer that needs to be repaired. This reduces the scope of power outages and improves the continuity and reliability of power supply.

[0003] A search revealed that Chinese utility model patent CN214478472U discloses a ring main unit with adjustable pre-drilled holes. The ring main unit includes a bottom plate and a top plate. A base is located at the upper center of the bottom plate, and a shell is located at the upper end of the base. The top plate is located at the upper end of the shell. An opening / closing door is located at the front center of the shell, and a square groove is located on the outer side of the door. A handle groove is located at the center of the right front side of the opening / closing door. A mounting plate is located at the center of the inner side of the shell, and extension plates are located at the center of both ends of the mounting plate. Bolts are located at the front ends of the extension plates. A pull rod is located at the center of the right inner side of the shell, and a sliding plate is located at the right end of the pull rod. This ring main unit with adjustable pre-drilled holes features a sliding plate with pre-drilled holes evenly distributed on it. This allows users to connect the required wiring to the mounting plate inside the device through appropriate pre-drilled holes, facilitating connection, operation, and saving time.

[0004] Although the above technical solution solves the problem of adjusting the position of the reserved hole, the above technical solution uses the movement of the sliding plate to cover or expose the reserved hole. However, the movement of the sliding plate will cover or expose one row. Although a sealing plug will be used to plug it later, it will still take up a lot of workers' time. Utility Model Content

[0005] Technical problems to be solved

[0006] In order to overcome the problem that existing ring network boxes with adjustable reserved hole positions cannot freely adjust the reserved holes, this utility model provides a ring network box with adjustable reserved hole positions that allows for free adjustment of the reserved hole positions.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a ring network box that facilitates adjustment of the position of pre-drilled holes, comprising:

[0009] Ring mesh box;

[0010] Mounting plate, which is fixedly installed inside the ring network box;

[0011] Several pre-drilled holes are arranged in a matrix on both sides of the ring main unit; and

[0012] A shielding assembly is installed inside the ring network box. The shielding assembly includes a sliding frame, which is fixedly disposed on the inner walls of both sides of the ring network box. Multiple guardrails are fixedly disposed inside the sliding frame. Each guardrail has a shielding block slidably disposed inside it, corresponding to the number of reserved holes. One end of a spring is fixedly disposed on the shielding block, and the other end of the spring is slidably disposed against the inner wall of the sliding frame. A driving assembly is installed inside the sliding frame.

[0013] Preferably, the drive assembly includes a threaded hole, which is formed at one end of the blocking block. A plurality of screws are rotatably disposed within the sliding frame, each screw being adapted to the threaded hole. One end of each screw passes through the ring mesh box, and a transmission assembly is fixedly disposed on the extension section of the screw.

[0014] Furthermore, the transmission assembly includes pulleys corresponding to the number of screws, the pulleys are fixedly disposed at one end of the screws, belts are driven between each pulley, and a handle is fixedly disposed on the pulley located in the middle.

[0015] Furthermore, the belts are arranged in a crisscross pattern.

[0016] In a further embodiment, the side of the ring network box is provided with several horizontal grooves, which are connected to the reserved holes. A sliding column is fixedly provided on the top of the guardrail, and the sliding column is slidably disposed in the horizontal groove.

[0017] Based on the aforementioned scheme, a gate is rotatably installed on the ring network box.

[0018] Based on the aforementioned solution, the shielding block is made of elastic and wear-resistant rubber material, and its shape is square to match the reserved hole.

[0019] Beneficial effects

[0020] This ring mesh box, which facilitates the adjustment of the reserved hole positions, has a corresponding individually sliding blocking block for each reserved hole. Unlike existing technologies that use sliding plates to block or expose a row of reserved holes, this solution allows for more precise control of the opening and closing state of each reserved hole. Workers can open or close only the required reserved holes according to actual needs, without having to operate on the entire row of reserved holes due to the movement of sliding plates as in existing technologies. This avoids unnecessary exposure or blocking of reserved holes, thus saving workers time in subsequent use of sealing plugs to handle excess reserved holes. A spring is fixedly installed, with the other end of the spring sliding against the inner wall of the sliding frame. This design makes the operation of the blocking block more convenient. When the reserved hole is not needed, the spring can automatically push the blocking block back to its original position to block the reserved hole, reducing the number of manual operation steps for workers. Moreover, when the reserved hole needs to be opened, the blocking block can be gently pushed against the spring force. The operation is simple and labor-saving, improving work efficiency and allowing for more flexible adjustment of the use of the reserved hole. Whether multiple scattered reserved holes or adjacent reserved holes are needed, it can be achieved more easily. Attached Figure Description

[0028] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See Figures 1-6 A ring network box that facilitates adjustment of the position of the reserved holes includes a ring network box 1, a mounting plate 17, a number of reserved holes 2, and a shielding component 3.

[0030] The ring main body 1 is the main structure of the entire device, providing space for the installation and housing of other components. The mounting plate 17 is fixedly installed inside the ring main body 1, used to install and fix electrical components or other equipment inside the ring main body 1, providing support and fixation to ensure the stability of the equipment within the ring main body 1. Pre-drilled holes 2 are arranged in a matrix on both sides of the ring main body 1. These holes 2 are used to pass through cables, wires, and other lines, providing channels for line access and exit. The matrix distribution design of the pre-drilled holes 2 can meet the needs of different line access locations and quantities, improving the versatility and flexibility of the ring main body 1. The sliding frame 4 is fixedly installed on the inner walls of both sides of the ring main body 1, providing the installation foundation for the entire shielding structure. Multiple guardrails 5 are fixedly installed inside the sliding frame 4, dividing the sliding frame 4 into multiple sections. Each area corresponds to a certain number of reserved holes 2. Each guardrail 5 has a sliding blocking block 6 corresponding to the number of reserved holes 2. The blocking block 6 can slide within the guardrail 5 to block or open the reserved holes 2. One end of the blocking block 6 is fixedly installed on the blocking block 6, and the other end of the spring 7 is connected to the inner wall of the sliding frame 4. The function of the spring 7 is to provide a restoring force for the blocking block 6. When the drive component 8 does not apply external force, the blocking block 6 is held in the initial position under the action of the spring 7, thus blocking the reserved holes 2. The blocking block 6 is made of elastic and wear-resistant rubber material, and its shape is square to fit the reserved holes 2. The blocking block is used to block the reserved holes. The elasticity of the rubber material allows it to better fit the edge of the reserved holes, enhance the sealing effect, and prevent dust, moisture and other impurities from entering the ring network box.

[0031] First, refer to Figure 2 and Figure 3 In this embodiment, the drive assembly 8 includes a threaded hole 9, which is opened at one end of the blocking block 6. Multiple screws 10 are rotatably arranged inside the sliding frame 4, and each screw 10 is adapted to the threaded hole 9. When the screw 10 rotates, due to the transmission action of the thread, the blocking block 6 that cooperates with the screw 10 will slide inside the guardrail 5, thereby realizing the opening or closing operation of the reserved hole 2. One end of the screw 10 passes through the ring mesh box 1, and its extension is fixedly provided with a transmission assembly 11 for driving the rotation of the screw 10.

[0032] Then, refer to Figure 2 and Figure 3 In this embodiment, the transmission assembly 11 includes pulleys 12 corresponding to the number of screws 10. The pulleys 12 are fixedly mounted on one end of the screws 10, and the pulleys 12 are connected to each other by belts 13. A handle 18 is fixedly mounted on the middle pulley 12. The operator can rotate the middle pulley 12 by rotating the handle 18. Through the transmission of the belts 13, the other pulleys 12 and the screws 10 rotate synchronously, so as to realize the simultaneous adjustment of multiple blocking blocks 6. The belts 13 are arranged in an up-and-down cross pattern. This arrangement can ensure that the transmission direction between the pulleys 12 is correct and that the rotation direction of the screws 10 is consistent, so that the blocking blocks 6 can move in the expected direction.

[0033] Secondly, see Figure 2 In this embodiment, the side of the ring mesh box 1 is provided with several horizontal grooves 14, which are connected to the reserved holes 2. A sliding column 15 is fixedly provided on the top of the guardrail 5. The sliding column 15 is slidably disposed in the horizontal groove 14. The horizontal groove 14 and the sliding column 15 provide a sliding track for the guardrail 5, ensuring that the guardrail 5 can move smoothly during the adjustment process. At the same time, they also play a limiting role, ensuring that the position of the guardrail 5 and the blocking block 6 is accurate.

[0034] Finally, see Figure 1 In this embodiment, a baffle 16 is rotatably provided on the ring network box 1. The baffle 16 is used to protect the equipment and lines inside the ring network box 1 and prevent dust, debris and other objects from entering the ring network box 1. It also provides a certain degree of safety and aesthetics.

[0035] Working principle:

[0036] When using this ring main unit that facilitates the adjustment of the reserved hole position, first open the gate 16 of the ring main unit 1. Determine the position of the reserved hole 2 to be used according to the actual line access requirements. Rotate the handle 18 located on the middle pulley 12 to drive the middle pulley 12 to rotate. Since the pulleys 12 are connected by belts 13 arranged in a crisscross pattern, the other pulleys 12 will rotate synchronously, thereby driving the screw 10 connected to them to rotate. When the screw 10 rotates, the worker presses the corresponding blocking block 6 with his hand. The screw 10 engages with the threaded hole 9 on the blocking block 6, driving the blocking block 6 to slide inside the guardrail 5, so that the blocking block 6 corresponding to the reserved hole 2 to be used is moved away from the reserved hole 2, opening the reserved hole 2. The blocking block 6 corresponding to the reserved hole 2 that is not used remains in the original position and continues to be pushed by the spring 7 to block the reserved hole 2. After the reserved hole 2 is opened, cables, wires and other lines are passed through the selected reserved hole 2 into the ring main unit 1 and connected to the corresponding electrical components or equipment on the mounting plate 17.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
