Description

Technical Field

[0001] This invention relates to the field of ring network box technology, specifically a modular adjustable ring network box. Background Technology

[0002] Modular unit adjustable ring main unit (MMBG) is a type of equipment used in power systems, primarily for ring network power supply in distribution networks. Its core feature lies in its modular design; the equipment consists of multiple independent functional modules that can be flexibly added or removed according to actual needs, adapting to distribution networks of varying scales and complexities. During installation, the grounding grid is first installed according to specifications to ensure the grounding resistance meets requirements. Then, a crane is used to hoist the MMBG onto the foundation, and a level is used to adjust its levelness, ensuring stable installation. After adjusting its horizontal position, bolts are used to fix the MMBG to the foundation, ensuring it will not move due to vibration or external forces. Once the connection is stable, it can be put into subsequent use.

[0003] Traditional modular adjustable ring main units (RMUs) typically consist of multiple functional modules, including switch modules, transformer modules, control units, and protection devices. While this modular design improves the scalability and maintenance convenience of the equipment, it also results in a large overall size and a significant space requirement. The weight and size of the MMU necessitate the use of large equipment, such as cranes and forklifts, for its movement. However, in short-distance movement scenarios (such as adjustments at construction sites, inside factories, or in power distribution rooms), the operating space for large equipment is often limited, making it difficult to operate flexibly. In narrow or complex environments, the movement and operation of large equipment may interfere with surrounding facilities and even pose safety hazards.

[0004] When moving a modular adjustable ring main unit, it is usually necessary to disassemble each of its functional modules. Since the modules are tightly connected by electrical connectors such as cables and busbars, the disassembly process requires not only professional tools and techniques, but also strict adherence to operating procedures to avoid damaging the equipment or causing safety hazards. In environments with limited space, the movement and installation of the equipment may require the temporary removal or adjustment of surrounding facilities, which increases the complexity and cost of the operation.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing modular adjustable ring network box. Summary of the Invention

[0006] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the prior art. Specifically, the purpose of the present invention is to provide a modular unit adjustable ring main cabinet to solve the problem that in the modular design of the modular unit adjustable ring main cabinet, due to the large volume and heavy weight of the equipment, large equipment is required for moving during movement, but the operating space of the large equipment is often limited during short-distance movement, making it difficult to be flexibly implemented, increasing the complexity and cost of operation.

[0007] To achieve the above object, the present invention provides the following technical solution: A modular unit adjustable ring main cabinet includes a ring main cabinet body, and further includes a base that is modularly combined and arranged at the bottom of the ring main cabinet body and can be freely spliced, a chute that is equally angled and opened on the upper surface of the base to cooperate with the movement of the ring main cabinet body, and a positioning component installed inside the base;

[0008] The positioning component further includes:

[0009] A connecting piece that can lock the connection of adjacent bases by using the ring main cabinet body.

[0010] Preferably, a fixing column is fixedly connected inside the base, and the connecting piece is slidably connected to the fixing column.

[0011] Preferably, a sliding plate is fixedly connected to the outer wall of the connecting piece, a limiting block is fixedly connected to the bottom of the sliding plate, the sliding plate is located inside the fixing column, and an opening for cooperating with the movement of the sliding plate is opened on one side of the fixing column.

[0012] Preferably, a spring is wound around the outer wall of the connecting piece, one end of the spring is fixedly connected to the bottom of the sliding plate, and the other end of the spring is fixedly connected to the bottom end inside the fixing column.

[0013] Preferably, a connecting groove is opened on one side of the base, and a limiting groove for positioning the limiting block is opened at the bottom of one side of the connecting groove.

[0014] Preferably, a plurality of groups of universal balls are fixedly connected to the bottom of the ring main cabinet body at equal distances and evenly;

[0015] The chute is designed as a "rice" - shaped slide rail, and the cross - section of the chute is an arc - shaped setting that slidably matches the lower end of the universal ball;

[0016] A fixing groove for cooperating with the seating of the universal ball is opened at the center of the "rice" - shaped slide rail.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The connecting piece slides inside the base by moving the ring main body. When the ring main body moves to the top of the connecting piece, its own weight drives the connecting piece to slide into the base. As the connecting piece slides into the base, it drives the sliding plate to move down synchronously along one side of the connecting groove. The lower end of the sliding plate is fixedly connected to a limit block. The limit block and the limit groove in the connecting groove cooperate with each other to form a stable connection structure, which allows for flexible and free combination between each two sets of bases. This ensures the stability of the equipment during movement, improves the convenience of operation, significantly reduces the complexity and cost of movement, and reduces dependence on the external environment, achieving the effect of facilitating short-distance movement of the ring main body.

[0030] 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.

[0031] Please see Figures 1 to 10 The present invention provides a technical solution: a modular unit adjustable ring network box, including a ring network box body 12, a base 1 that is modularly combined and set at the bottom of the ring network box body and can be freely spliced, a sliding groove 7 that is opened at equal angles on the upper surface of the base 1 to cooperate with the movement of the ring network box body 12, and a positioning component installed inside the base 1.

[0032] The positioning components also include:

[0033] Connector 5 can be used to lock the connection between adjacent bases 1 using the ring network box body.

[0034] In specific implementation, according to Figure 1 and Figure 3 The ring mesh box body 12 is located at the center of the spliced ​​base 1. First, push the ring mesh box body 12 to the upper left corner of the spliced ​​base 1. At this time, the ring mesh box body 12 moves and releases the lock on the outermost base 1. First, pull out the first base 1 downwards. The sliding plate 3 fixedly connected to one side of the first base 1 slides inside the connecting groove 8 opened on one side of the second base 1, pulling the first base 1 out from inside the spliced ​​base 1. Through the same steps, pull out the second, third and fourth base 1 downwards in sequence. When the first base 1 is pulled out... After the four base pieces 1 are removed, the lock between the fourth base piece 1 and the fifth base piece 1 is released, and then the fifth base piece 1 is pulled out to the right. The sliding plate 3 fixedly connected to one side of the fifth base piece 1 slides inside the connecting groove 8 opened on one side of the sixth base piece 1, and the fifth base piece 1 is pulled out from the spliced ​​base piece 1. The sixth and seventh base pieces 1 are pulled out to the right in the same way. At this time, all the base pieces 1 on the outside of the ring network box body 12 are removed. The base pieces 1 can be spliced ​​again according to the subsequent movement direction, so as to move the ring network box body 12.

[0035] In specific implementation, according to Figure 3When moving the ring network box body 12, the base 1 needs to be spliced ​​in its forward direction. Align the side of the second base 1 with the connecting groove 8 with the side of the first base 1 with the sliding plate 3 fixedly connected. Connect the second base 1 with the first base 1. Connect the third base 1 with the second base 1 through the same steps. After the three base 1 are fixedly connected, align the side of this whole with the connecting groove 8 with the side of the forward direction with the sliding plate 3 fixedly connected. Push this whole to the left to splice it with the base 1, thus achieving the effect of facilitating the movement of the ring network box body 12.

[0036] In practice, the bases 1 can be freely spliced ​​together according to the size and shape of the ring network box body 12. When the installation position of the ring network box body 12 is too small and it is necessary to repair the faulty side and rotate it, the ring network box body 12 is pushed to one side to release the lock on the outermost base 1. The removed base 1 is then spliced ​​together in the rotation direction. By pushing the ring network box body 12 to rotate, the rotation of the ring network box body 12 causes the universal ball 10 at its bottom to slide in the slide groove 7, thereby achieving the effect of facilitating the maintenance of the ring network box body 12.

[0037] As a further embodiment of the present invention, a fixing post 2 is fixedly connected inside the base 1, and the connector 5 is slidably connected to the fixing post 2.

[0038] In practice, a fixed column 2 is fixedly connected inside the base 1, and the connector 5 and the fixed column 2 are connected by sliding to achieve relative movement, so that the connector 5 can slide up and down inside the fixed column 2, thereby driving the sliding plate 3 fixedly connected to it to move synchronously. This not only realizes the flexible cooperation between the base 1 and the connector 5, but also provides basic support for locking, unlocking and position adjustment of the base 1, enhancing the stability and ease of operation of the equipment.

[0039] As a further embodiment of the present invention, a sliding plate 3 is fixedly connected to the outer wall of the connector 5, a limiting block 6 is fixedly connected to the bottom of the sliding plate 3, the sliding plate 3 is located inside the fixed column 2, and an opening is provided on one side of the fixed column 2 to cooperate with the movement of the sliding plate 3.

[0040] In specific implementation, a sliding plate 3 is fixedly connected to the outer wall of the connector 5, and a limiting block 6 is fixedly connected to the bottom of the sliding plate 3. The sliding plate 3 is located inside the fixed column 2, and an opening that cooperates with the sliding plate 3 is opened on one side of the fixed column 2, so that the sliding plate 3 can slide inside the fixed column 2 along the direction of the opening, while driving the limiting block 6 to move. Through the movement of the sliding plate 3, the connector 5 can flexibly adjust its position, thereby providing support for the splicing, disassembly or position adjustment of the base 1, ensuring the stability of the base 1 and the convenience of the splicing operation of the base 1.

[0041] As a further embodiment of the present invention, a spring 4 is wound around the outer wall of the connecting member 5. One end of the spring 4 is fixedly connected to the bottom of the sliding plate 3, and the other end of the spring 4 is fixedly connected to the inner bottom end of the fixed column 2.

[0042] In specific implementation, a spring 4 is wound around the outer wall of the connecting member 5. One end of the spring 4 is fixedly connected to the bottom of the sliding plate 3, and the other end is fixedly connected to the inner bottom end of the fixed column 2. By utilizing the elastic characteristics of the spring 4, a restoring force is provided for the sliding plate 3. When the connecting member 5 is subjected to the external force of the self-weight of the ring network cabinet body 12, the sliding plate 3 will slide along the fixed column 2, and the spring 4 will be compressed or stretched; when the external force disappears, the elastic restoring force of the spring 4 pushes the sliding plate 3 back to the initial position, thereby realizing the automatic reset function of the connecting member 5 and the sliding plate 3, enhancing the stability and reliability of the base 1, especially when the ring network cabinet body 12 needs to be frequently adjusted or moved.

[0043] As a further embodiment of the present invention, a connecting groove 8 is provided on one side of the base 1, and a limiting groove 9 for positioning the limiting block 6 is provided at the bottom of one side of the connecting groove 8.

[0044] In specific implementation, a connecting groove 8 is provided on one side of the base 1, and a limiting groove 9 is provided at the bottom of the connecting groove 8 for positioning the limiting block 6. Through the cooperation of the limiting block 6 and the limiting groove 9, precise connection and locking between the bases 1 are achieved. When the sliding plate 3 drives the limiting block 6 to move to the position of the limiting groove 9, the limiting block 6 meshes with the limiting groove 9 to form a stable locking state, ensuring the stability of the equipment during operation; when unlocking is required, the limiting block 6 disengages from the limiting groove 9, and the sliding plate 3 can move freely, which not only improves the convenience of splicing and disassembling the base 1, but also enhances the stability and safety of the base 1 during use, and is suitable for scenarios where the ring network cabinet body 12 needs to be frequently adjusted or moved.

[0045] As a further embodiment of the present invention, a plurality of universal balls 10 are fixedly connected to the bottom of the ring network cabinet body 12 at equal distances and evenly;

[0046] The chute 7 is designed as a "rice" - shaped slide rail, and the cross - section of the chute 7 is an arc - shaped setting that slidably matches the lower end of the universal ball 10;

[0047] A fixing groove 11 for fitting the seating of the universal ball 10 is provided at the center of the "rice" - shaped slide rail.

[0048] In practice, multiple sets of universal balls 10 are evenly and uniformly fixed to the bottom of the ring network box body 12. These universal balls 10 can slide freely within the slide groove 7. The slide groove 7 adopts a "rice" shaped slide rail design, and its cross-section is an arc structure that matches the sliding of the lower end of the universal balls 10, ensuring that the universal balls 10 move smoothly within the slide groove 7. A fixing groove 11 is provided at the center of the "rice" shaped slide rail to cooperate with the positioning of the universal balls 10. When the ring network box body 12 moves to the center position of the slide groove 7, the universal balls 10 fall into the fixing groove 11, realizing the stable fixation of the ring network box body 12 and the base 1. When it is necessary to move, the universal balls 10 disengage from the fixing groove 11 and slide along the slide groove 7, realizing the flexible adjustment of the equipment. This not only improves the ease of movement of the equipment, but also enhances the stability and positioning accuracy of the base 1.

[0049] Working principle: When using this modular adjustable ring network box, firstly, the base 1 is spliced ​​together, and then the ring network box body 12 is placed on top of the spliced ​​base 1. When it is necessary to splice two sets of base 1, first align the side of one base 1 with the sliding plate 3 fixedly connected to it with the side of the connecting groove 8 opened on the other base 1. Then, by pushing the base 1 with the sliding plate 3 fixedly connected, the sliding plate 3 slides inside the connecting groove 8. At this time, the two sets of base 1 are initially connected, but not yet locked.

[0050] When the ring mesh box body 12 moves to the top of the base 1 after splicing, the weight of the ring mesh box body 12 causes the connector 5 at the top of the base 1 to slide inside the fixed column 2. The sliding of the connector 5 causes the sliding plate 3 fixedly connected to it to slide inside the connecting groove 8. Since the bottom of the sliding plate 3 is fixedly connected to the limit block 6, the limit block 6 engages with the limit groove 9 opened inside the connecting groove 8, so that each two sets of base 1 are locked together. When the ring mesh box body 12 moves to the outside of the connector 5, the connector 5 moves up, and the sliding plate 3 is reset under the action of the spring 4 fixedly connected to its bottom. At this time, the lock between the two sets of base 1 is released, and the base 1 can be freely spliced.

[0051] When the ring mesh box body 12 moves to the top of the base 1 after splicing, the weight of the ring mesh box body 12 drives the connector 5 at the top of the base 1 to slide inside the fixed column 2. The sliding of the connector 5 further drives the sliding plate 3 fixedly connected to it to slide inside the connecting groove 8. Since the bottom of the sliding plate 3 is fixedly connected to the limit block 6, and the limit block 6 and the limit groove 9 opened inside the connecting groove 8 engage with each other, the locking connection between each pair of bases 1 is realized, ensuring the stability and safety of the equipment during operation. When it is necessary to release the locking state, the ring mesh box body 12 is moved away from the outside of the connector 5. At this time, the connector 5 moves upward under the action of the sliding plate 3. At the same time, the sliding plate 3 is reset under the elastic action of the spring 4 fixedly connected to its bottom. The limit block 6 and the limit groove 9 are disengaged, thereby releasing the lock between the two pairs of bases 1. At this time, the bases 1 can be freely spliced ​​again, which is convenient for the adjustment or movement of the equipment.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
