Description

Technical Field

[0001] This utility model relates to the field of substation ring main unit technology, specifically a ring main unit with functional compartments. Background Technology

[0002] In power systems, substation ring main units, as core equipment of the distribution network, undertake the key functions of power distribution, protection, and control.

[0003] Traditional ring main units (RMMs) typically employ fixed structures for their functional compartments. The compartment layout, equipment configuration, and electrical connections are predetermined at the factory, making it difficult to adapt to diverse needs in different scenarios. With the integration of new energy sources, changes in load density, and the diversification of grid operation modes, users have increasingly urgent needs for RMMs in terms of functional expandability, dynamic allocation of compartment space, and rapid equipment replacement. As a result, some RMMs with adjustable spatial layouts have emerged. These adjustable RMMs generally use movable partitions. The stress point of these movable partitions is often near the outer edge, and this single-point stress can cause slight deformation of the partition, leading to jamming when adjusting functional compartments, and in severe cases, even partition deformation. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a ring network box with functional compartments.

[0005] A ring network box with functional compartments includes a box body, a top cover on the top of the box body, a bottom plate on the bottom, several partitions inside the box body, and a horizontally extending slide rail on the bottom plate with several limiting holes.

[0006] Several layers of horizontally extending telescopic plates are connected between adjacent partitions inside the box. Fixing components are provided on the inner and outer sides of the partitions. A limiting component is inserted into the outer fixing component near the door. The upper part of the limiting component is higher than the outer fixing component, and the top is detachably connected to the handle rod. The bottom of the limiting component is slidably connected in the slide rail.

[0007] The handle includes a laterally extending adjustment rod, and a first and a second insertion part connected to its lower side, wherein the first insertion part can be detachably connected to the outer fixing member, and the second insertion part can be inserted into the inner fixing member.

[0008] There is one inner fastener and multiple outer fasteners arranged vertically, with the uppermost outer fastener being the same height as the inner fastener.

[0009] The distance from the inner and outer fasteners on the same partition to the center line of the partition is equal.

[0010] The first and second connectors are perpendicularly connected to the adjusting rod.

[0011] After the holding rod is inserted, the end of the adjusting rod extends laterally out of the partition.

[0012] After the handle is inserted, the end extends laterally beyond the partition by more than 10 centimeters.

[0013] The second connector can be inserted below the inner fixing member.

[0014] The limiting component is a vertically extending round tube with an elastic element embedded in the upper end for detachable connection with the handle.

[0015] The first insertion part is a vertically extending round tube, and one or more grooves are provided on the lower outer surface to cooperate with the elastic element.

[0016] The lower end of the limiting member is provided with an insertion part, and the cross-sectional area of ​​the insertion part gradually decreases from top to bottom.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention uses fixing components set inside and outside the partition to create multiple force points between the partition and the holding rod. When adjusting the internal space of the ring network box, it ensures that the partition is subjected to force both inside and outside and is adjusted simultaneously, preventing uneven force on the partition and deformation. Unlike the partition jamming phenomenon that may occur in the prior art, the holding rod and the partition have two force points, which can drive the telescopic plate in a balanced manner, making the process of adjusting the compartment smoother.

[0019] The holding rod and the limiting component are detachably connected via an elastic element, allowing for plug-and-play operation. The operator inserts and grasps the extended holding rod, gently lifts it upwards to pull the limiting component out of the limiting hole, then moves the partition horizontally to the desired position, inserts the limiting component back into the limiting hole, and pulls out the holding rod to complete the adjustment. After adjusting the partition spacing, the operator can directly remove the holding rod. Furthermore, a single holding rod can adjust the position of all partitions within the same ring main unit, making it highly practical and cost-effective. Attached Figure Description

[0024] 1. Base plate; 11. Slide rail; 12. Limiting hole; 2. Box body; 21. Partition plate; 22. Telescopic plate; 23. Handling rod; 24. Limiting component; 25. Fixing component; 3. Top cover. Detailed Implementation

[0025] Example 1

[0026] The technical solution of this utility model is as follows:

[0027] A ring network box with functional compartments includes a box body 2, a top cover 3 on the top of the box body 2, a bottom plate 1 on the bottom, and a plurality of partitions 21 inside the box body 2.

[0028] Furthermore, the box 2 has an overall rectangular structure, with a sloping top cover 3 for rain protection and drainage.

[0029] The base plate 1 has a horizontally extending slide rail 11, and a number of limiting holes 12 are provided on the slide rail 11;

[0030] Inside the box 2, there are several layers of horizontally extending telescopic plates 22 connecting adjacent partitions 21. The inner and outer sides of the partitions 21 are respectively provided with fixing members 25. The outer fixing member 25 near the door is inserted with a limiting member 24. The upper part of the limiting member 24 is higher than the outer fixing member 25, and the top is detachably connected to the handle rod 23. The bottom of the limiting member 24 is slidably connected in the slide rail 11.

[0031] Furthermore, the telescopic panel 22 adopts a nested structure, and the layers can slide relative to each other. The design of the telescopic panel 22 allows the width of the compartment to be infinitely adjusted to meet the installation requirements of equipment of different sizes.

[0032] The handle 23 includes a laterally extending adjustment rod and a first and a second insertion part connected to its lower side, wherein the first insertion part can be detachably connected to the outer fixing member 25 and the second insertion part can be inserted into the inner fixing member 25.

[0033] Furthermore, the second connector and the adjusting rod are integrally formed, reducing production costs, while the first connector and the adjusting rod are connected by welding.

[0034] The double-plug design of the handle 23 ensures a secure connection, and disassembly and assembly can be completed simply by lifting.

[0035] There is one inner fastener 25 and multiple outer fasteners 25 arranged vertically. The uppermost outer fastener 25 is at the same height as the inner fastener 25.

[0036] Furthermore, the fixing member 25 is rectangular, with the middle part protruding away from the partition. The inner fixing member 25 and the partition 21 form a space for insertion with the second insertion part, and the outer fixing member 25 and the partition 21 form a space for connection with the limiting member 24. At the same time, the multiple outer fixing members can provide a movement trajectory for the limiting member 24.

[0037] The distances from the inner and outer fasteners 25 to the centerline of the partition 21 are equal. The symmetrical arrangement of the inner and outer fasteners 25 ensures that the partition 21 is subjected to balanced forces, thereby improving the overall structural stability.

[0038] The first and second connectors are perpendicularly connected to the adjusting rod.

[0039] After the holding rod 23 is inserted, the end of the adjusting rod extends laterally out of the partition 21.

[0040] After the handle 23 is inserted, the end extends laterally beyond the partition 21 by a distance greater than 10 centimeters.

[0041] The extended design of the handle 23 is ergonomic, allowing operators to make adjustments within a limited space.

[0042] The second connector can be inserted below the inner fixing member 25.

[0043] The limiting component 24 is a vertically extending circular tube with an elastic element embedded at the upper end. (See reference) Figure 2 It is used for detachable connection with the handle 23.

[0044] This design provides minimal resistance, making it easy to insert the holding rod 23 and the limiting member 24 to complete the detachable connection. At the same time, it provides a certain amount of resistance, allowing the limiting member 24 to be lifted and disengaged from the limiting hole after the holding rod 23 is inserted into the limiting member 24.

[0045] The first insertion part is a vertically extending round tube, and one or more grooves are provided on the lower outer surface to cooperate with the elastic element.

[0046] The lower end of the limiting member 24 is provided with an insertion part, and the cross-sectional area of ​​the insertion part gradually decreases from top to bottom.

[0047] The precise positioning and reliable fixing of the partition 21 can be achieved through the cooperation of the limiting hole 12 and the limiting member 24; and the design of this insertion part shape can play a guiding role when the limiting member 24 is not fully aligned with the limiting hole 12.

[0048] In use, the operator inserts and holds the extended handle 23, gently lifts it upwards to pull the limiting member 24 out of the limiting hole 12, then moves the partition 21 horizontally to the desired position, inserts the limiting member 24 into the limiting hole 12, holds the limiting member 24, pulls out the handle 23, and adjusts the position of the next partition 21. The entire process requires no auxiliary tools and can be completed by a single person.

[0049] This invention uses fixing components set inside and outside the partition to create multiple force points between the partition and the holding rod. When adjusting the internal space of the ring network box, it ensures that the partition is subjected to force both inside and outside and is adjusted simultaneously, preventing uneven force on the partition and deformation. Unlike the partition jamming phenomenon that may occur in the prior art, the holding rod and the partition have two force points, which can drive the telescopic plate in a balanced manner, making the process of adjusting the compartment smoother.

[0050] The holding rod and the limiting component are detachably connected via an elastic element, allowing for plug-and-play operation. The operator inserts and grasps the extended holding rod, gently lifts it upwards to pull the limiting component out of the limiting hole, then moves the partition horizontally to the desired position, inserts the limiting component back into the limiting hole, and pulls out the holding rod to complete the adjustment. After adjusting the partition spacing, the operator can directly remove the holding rod. Furthermore, a single holding rod can adjust the position of all partitions within the same ring main unit, making it highly practical and cost-effective.
