Description

Technical Field

[0001] The present invention relates to the technical field of ring main unit cabinets, and particularly to a modular unit adjustable ring main unit cabinet. Background Art

[0002] The modular unit adjustable ring main unit cabinet is a device used in the power system, mainly for the ring network power supply of the distribution network. The core feature of the modular unit adjustable ring main unit cabinet lies in its modular design. The device consists of multiple independent functional modules, and these modules can be flexibly increased or decreased according to actual needs to adapt to distribution networks of different scales and complexities. When installing the ring main unit cabinet, first install the grounding grid according to the specifications to ensure that the grounding resistance meets the requirements. Then use a crane to hoist the ring main unit cabinet onto the foundation, and use a level to adjust the levelness of the device to ensure the stable installation of the device. After adjusting its horizontal position, use bolts to fix the ring main unit cabinet on the foundation to ensure that the device will not move due to vibration or external forces. After its connection is stable, it can be put into subsequent use.

[0003] In the actual use process of the traditional modular unit adjustable ring main unit cabinet, since the modular unit adjustable ring main unit cabinet usually consists of multiple functional modules, including switch modules, transformer modules, control units, protection devices, etc., although this modular design improves the scalability and maintenance convenience of the device, it also results in a relatively large overall volume of the device and occupies more space. The weight and volume of the modular unit adjustable ring main unit cabinet determine that its movement depends on large equipment such as cranes and forklifts. However, in short-distance movement scenarios (such as construction sites, inside factories, or substation adjustments), the operating space of large equipment is often limited and it is difficult to operate flexibly. In narrow or complex space environments, the movement and operation of large equipment may interfere with surrounding facilities and even pose safety hazards.

[0004] When moving the modular unit adjustable ring main unit cabinet, it is usually necessary to disassemble its various 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 compliance with operating procedures to avoid damaging the equipment or causing safety hazards. In an environment with limited space, the movement and installation of the equipment may require temporarily removing or adjusting surrounding facilities, increasing the complexity and cost of the operation.

[0005] In view of the above problems, there is an urgent need to innovate and design on the basis of the original modular unit adjustable ring main unit cabinet. 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 due to the large volume and heavy weight of the modular unit adjustable ring main cabinet in modular design, large equipment is needed for moving during movement, but the operation space of large equipment is often limited during short-distance movement, making it difficult to operate flexibly, 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, including a ring main cabinet body, further including a base modularly combined and arranged at the bottom of the ring main cabinet body and capable of being freely spliced, a chute equally angled and opened on the upper surface of the base for cooperating 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 universal ball to be seated 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] By moving the main body of the ring network box, the connecting piece slides inside the base. When the main body of the ring network box moves to the top of the connecting piece, the connecting piece is driven to slide inside the base by its own weight. When the connecting piece slides inside the base, it drives the sliding plate to move downward synchronously along one side of the connecting groove. A limiting block is fixedly connected to the lower end of the sliding plate. By the cooperation of the limiting block and the limiting groove in the connecting groove, a stable connection structure is formed, enabling flexible free combination between every two groups of bases, ensuring the stability of the equipment during movement, improving the operation convenience, significantly reducing the complexity and cost of movement, and at the same time reducing the dependence on the external environment, achieving the effect of facilitating the short-distance movement of the ring network box.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 10 , the present invention provides a technical solution: a modular unit adjustable ring main cabinet, including a ring main cabinet body 12, and further including a base 1 that is modularly combined and arranged at the bottom of the ring main cabinet body and can be freely spliced, a chute 7 that is equally angled and opened on the upper surface of the base 1 to cooperate with the movement of the ring main cabinet body 12, and a positioning component installed inside the base 1;

[0032] The positioning component further includes:

[0033] A connecting piece 5 that can lock the connection between adjacent bases 1 by using the ring main cabinet body.

[0034] In a specific implementation, according to Figure 1 and Figure 3 , the ring main cabinet body 12 is located at the exact center of the spliced base 1. First, push the ring main cabinet body 12 to the upper left corner of the spliced base 1. Since the movement of the ring main cabinet body 12 releases the lock on the outermost base 1 at this time, in the first step, pull out the first base 1 downward. The sliding plate 3 fixedly connected to one side of the first base 1 slides inside the connection groove 8 opened on one side of the second base 1, and the first base 1 is pulled out from the spliced bases 1. By the same steps, the second, third, and fourth bases 1 are sequentially pulled out downward. After the fourth base 1 is pulled out, unlock the lock between the fourth base 1 and the fifth base 1, and then pull out the fifth base 1 to the right. The sliding plate 3 fixedly connected to one side of the fifth base 1 slides inside the connection groove 8 opened on one side of the sixth base 1, and the fifth base 1 is pulled out from the spliced bases 1. By the same steps, the sixth and seventh bases 1 are sequentially pulled out to the right. At this time, all the bases 1 outside the ring main cabinet body 12 are removed, and the bases 1 can be spliced again according to the subsequent moving direction, so as to move the ring main cabinet body 12.

[0035] In a specific implementation, according to Figure 3, when moving the main body 12 of the ring network cabinet, it is necessary to splice the base 1 in its advancing direction. Align the side of the second base 1 with the connecting groove 8 with the side of the first base 1 fixedly connected with the sliding plate 3, and connect the second base 1 with the first base 1 through the first base 1. Connect the third base 1 with the second base 1 through the same steps. After the three bases 1 are fixedly connected, align the side of this whole with the connecting groove 8 with the side of the sliding plate 3 fixedly connected to the advancing direction side, and push this whole to the left to splice it with the base 1, achieving the effect of facilitating the movement of the main body 12 of the ring network cabinet.

[0036] In specific implementation, the bases 1 can be freely spliced according to the size and shape of the main body 12 of the ring network cabinet. When it is necessary to rotate the direction for repairing the faulty side due to the narrow installation position of the main body 12 of the ring network cabinet, push the main body 12 of the ring network cabinet to move to one side to release the locking of the outermost base 1, splice the removed base 1 in the rotating direction, and rotate the main body 12 of the ring network cabinet by pushing. The rotation of the main body 12 of the ring network cabinet drives the universal balls 10 at its bottom to slide in the sliding grooves 7, thus achieving the effect of facilitating the repair of the main body 12 of the ring network cabinet.

[0037] As a further implementation scheme of the present invention, a fixed column 2 is fixedly connected inside the base 1, and the connecting piece 5 is slidably connected with the fixed column 2.

[0038] In specific implementation, a fixed column 2 is fixedly connected inside the base 1, and the connecting piece 5 and the fixed column 2 achieve relative movement through a sliding connection manner, enabling the connecting piece 5 to slide up and down inside the fixed column 2, thereby driving the sliding plate 3 fixedly connected thereto to move synchronously. This not only realizes the flexible cooperation between the base 1 and the connecting piece 5 but also provides basic support for the locking, unlocking, and position adjustment of the base 1, enhancing the stability and operation convenience of the device.

[0039] As a further implementation scheme of the present invention, a sliding plate 3 is fixedly connected to the outer wall of the connecting piece 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 for cooperating with the movement of the sliding plate 3 is provided on one side of the fixed column 2.

[0040] In specific implementation, a sliding plate 3 is fixedly connected to the outer wall of the connecting piece 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 cooperating with the sliding plate 3 is provided on one side of the fixed column 2, enabling the sliding plate 3 to slide inside the fixed column 2 along the opening direction and driving the limiting block 6 to move simultaneously. Through the movement of the sliding plate 3, the connecting piece 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 using 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 box 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 will push 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 box 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, the precise connection and locking between the bases 1 are realized. When the sliding plate 3 drives the limiting block 6 to move to the position of the limiting groove 9, the limiting block 6 engages 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 box 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 box body 12 at equal intervals and uniformly;

[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 specific implementation, multiple groups of universal balls 10 are fixedly connected to the bottom of the ring network box body 12 at equal distances and evenly. These universal balls 10 can slide freely within the sliding groove 7. The sliding groove 7 adopts a "rice" - shaped rail design, and its cross - section is an arc structure that slidably matches the lower end of the universal ball 10, ensuring smooth movement of the universal ball 10 within the sliding groove 7. A fixing groove 11 is provided at the center of the "rice" - shaped rail for cooperating with the setting and positioning of the universal ball 10. When the ring network box body 12 moves to the center position of the sliding groove 7, the universal ball 10 falls into the fixing groove 11, realizing the firm fixation of the ring network box body 12 and the base 1. When movement is required, the universal ball 10 disengages from the fixing groove 11 and slides along the sliding groove 7, realizing flexible adjustment of the device. This not only improves the mobility convenience of the device but also enhances the stability and positioning accuracy of the base 1.

[0049] Working principle: When using this modular unit adjustable ring network box, first splice the base 1, and then place the ring network box body 12 on the top of the spliced base 1. When it is necessary to splice every two groups of bases 1, first align the side of one base 1 fixedly connected with the sliding plate 3 with the side of the connecting groove 8 opened on the other base 1. Then, by pushing the base 1 fixedly connected with the sliding plate 3, the sliding plate 3 slides inside the connecting groove 8. At this time, a preliminary connection is achieved between the two groups of bases 1, but they are not yet locked.

[0050] When the ring network box body 12 moves to the top of the spliced base 1, the self - weight of the ring network box body 12 drives the connecting member 5 on the top of the base 1 to slide inside the fixed column 2. The sliding of the connecting member 5 drives the sliding plate 3 fixedly connected to it to slide inside the connecting groove 8. And because a limiting block 6 is fixedly connected to the bottom of the sliding plate 3, and the limiting block 6 meshes with the limiting groove 9 opened inside the connecting groove 8, locking connection is achieved between every two groups of bases 1. When the ring network box body 12 moves outside the connecting member 5, the connecting member 5 moves upward, and the sliding plate 3 resets under the action of the spring 4 fixedly connected to its bottom. At this time, the locking between the two groups of bases 1 is released, and the bases 1 can be freely spliced at this time.

[0051] When the main body 12 of the ring network box moves to the top of the base 1 after splicing is completed, the self-weight of the main body 12 of the ring network box drives the connecting member 5 at the top of the base 1 to slide inside the fixed column 2. The sliding of the connecting member 5 further drives the sliding plate 3 fixedly connected thereto to slide inside the connecting groove 8. Since the bottom of the sliding plate 3 is fixedly connected with a limiting block 6, and the limiting block 6 meshes with the limiting groove 9 opened inside the connecting groove 8, the locking connection between every two groups of bases 1 is realized, ensuring the stability and safety of the equipment during operation. When the locking state needs to be released, the main body 12 of the ring network box is moved away from the outside of the connecting member 5. At this time, the connecting member 5 moves upward under the action of the sliding plate 3. At the same time, the sliding plate 3 resets under the elastic action of the spring 4 fixedly connected to its bottom, and the limiting block 6 disengages from the meshing state with the limiting groove 9, thus releasing the locking between the two groups of bases 1. At this time, the bases 1 can be freely spliced again, facilitating 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 recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
