Description

Technical Field

[0001] This utility model belongs to the field of ring main unit basic technology and relates to a new type of ring main unit basic component. Background Technology

[0002] A ring main unit is an electrical device consisting of a set of power transmission and distribution equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or assembled into a modular ring main unit. Its core components are load switches and fuses, while the ring main unit foundation is the basis that supports the ring main unit.

[0003] Currently, there are generally two types of ring main unit foundations commonly found on the market. The first type involves casting the required foundation on-site; the second type involves manufacturing the complete ring main unit foundation at the production site, transporting it to the functional site, and then moving it to the designated location using a crane. The former has uncontrollable quality, while the latter requires larger equipment for transportation and installation, and may also cause installation difficulties in some site-restricted areas, resulting in poor performance in both types. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of ring main unit basic component, which aims to solve the problem of poor performance.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel ring main unit foundation component, including a base plate, a first side plate, a second side plate, a first top frame, a second top frame, a moisture-proof board body, and a manhole plate. The first side plate has a through-hole, and its cross-section is C-shaped. There are two first side plates, with their openings facing each other. The two ends of the two first side plates are connected to the second side plate, and the cross-sections of all the first and second side plates form a closed rectangle. The base plate is connected to the bottom of all the first and second side plates. The bottom of the first top frame abuts against the top of a portion of the first and second side plates, and the bottom of the second top frame abuts against the top of the remaining portion of the first and second side plates. Both the first and second top frames have rectangular cross-sections. The moisture-proof board body is connected to the inner side of the top of the first top frame, and the manhole plate is connected to the inner side of the top of the second top frame. The top of the first top frame is higher than the top of the second top frame.

[0006] The present invention is further configured such that a first slot is provided on the top of the base plate, the bottom of the first side plate and the second side plate are both located in the first slot, a U-shaped second slot is provided on the bottom of the first top frame, a U-shaped third slot is provided on the bottom of the second top frame, the two ends of the second slot and the third slot are connected, and the tops of the first side plate and the second side plate are both located in the second slot or the third slot.

[0007] The present invention is further configured such that there are two second side plates, the cross-section of the second side plate is an isosceles trapezoid, and the upper base of the isosceles trapezoid is located on the inner side and the lower base is located on the outer side. The edges at both ends of the first side plate are inclined, and the edges of the first side plate and the second side plate are in face-to-face contact.

[0008] The present invention is further configured such that the edge of the first side plate is provided with a first hole, the edge of the second side plate is provided with a second hole communicating with the first hole, and the invention also includes a positioning bolt and a positioning nut for fixing the first side plate and the second side plate. Two washers are sleeved on the positioning bolt, and the positioning bolt passes through the first hole and the second hole. Both the first hole and the second hole are countersunk holes.

[0009] The present invention is further configured such that a temporary hole is vertically provided at the top of both the first side plate and the second side plate, and a temporary rod that cooperates with the temporary hole is vertically provided at the bottom of both the first top frame and the second top frame.

[0010] The present invention is further configured such that a grit chamber with an upward-opening cover is provided at the bottom of the base plate, a first mesh body matching the shape of the opening of the grit chamber is provided at the top of the grit chamber, and an outlet is provided on the side of the grit chamber.

[0011] The present invention is further configured such that a drying hole is horizontally opened on the side of the first top frame, the drying hole is frustoconical, and the diameter of the inner side of the drying hole is smaller than the diameter of the outer side. A second mesh is provided on the inner side of the drying hole, and a third mesh is provided on the outer side. The second mesh and the third mesh respectively cover the two ends of the drying hole.

[0012] The present invention is further configured such that a positioning ring is fixedly provided on the top of the first top frame, and the projection of the positioning ring in the vertical direction is located within the projection of the first top frame in the vertical direction.

[0013] It also includes a grounding component, the top of which is connected to the positioning ring, the middle part is located inside the first top frame, and the bottom part is located outside the first top frame or is flush with the outside of the first top frame.

[0014] The present invention is further configured such that the inner wall of the second side plate is provided with a plurality of embedded plates, the embedded plates are provided with threaded holes, and cable brackets are horizontally provided on the embedded plates.

[0015] The present invention is further configured such that a plurality of moisture-proof boards are arranged in parallel, one side of each moisture-proof board has a mating groove, and the other side has a mating strip that mates with the mating groove. Two adjacent moisture-proof boards are connected by the mating strip and the mating groove. A first support groove is provided on the inner side of the top of the first top frame. Both ends of all moisture-proof boards overlap the inner wall of the first support groove, and the outer side of the moisture-proof boards located at the edge overlaps the inner wall of the first support groove.

[0016] The second top frame has a second support groove on its inner side. There are several manhole plates. Both ends of all the manhole plates overlap the inner wall of the second support groove, and the outer side of the manhole plates located at the edge overlaps the inner wall of the second support groove.

[0017] Compared with existing technologies, this utility model provides a novel ring main unit foundation component. Firstly, the base plate, first top frame, second top frame, first side plate, second side plate, moisture-proof board, manhole plate, etc., are all manufactured (or purchased directly) at an external site. Then, they are transferred to the site where they are needed in parts and assembled on-site. During assembly, the base plate is first transferred or hoisted (even with equipment, the lightweight and small size of the components reduces the requirements for hoisting machinery, making it easier to use and less demanding on the site) to the designated position. Then, the first and second side plates are installed in their designated positions on the base plate. Next, the first and second top frames are placed on top of the first and second side plates. Finally, the moisture-proof board is placed in its designated position on the first top frame, and the manhole plate is placed in its designated position on the second top frame. This forms a complete ring main unit foundation. In actual use, grouting or applying concrete to all joints is necessary to improve the foundation's waterproofing and structural strength. The through-hole is used in conjunction with cable ducts and other equipment to allow cables to pass through the ring main unit foundation.

[0018] Since the components in the ring main unit foundation of this application are manufactured in the factory or purchased directly in the form of individual parts (such as municipal manhole cover-style manhole plates and ALC moisture-proof boards), the quality is relatively controllable. Secondly, when transferring, transporting and assembling the components, the requirements for the site are lower and the actual operation is simpler because the components are lightweight and small in size. At the same time, the requirements for the equipment during on-site assembly are also lower.

[0019] The moisture-proof board is preferably made of lightweight concrete (standard part), which not only provides moisture protection and ensures the safety of the ring main unit, but also facilitates drilling for cable passage. Different ring main units require different amounts of holes, so the lightweight concrete material makes it easy for workers to drill on-site. The first top frame is higher than the second top frame, raising the ring main unit above the ground; however, the top of the second top frame is almost flush with the ground, allowing for manhole cover support for passage. During maintenance, simply opening the manhole cover provides easy access to the ring main unit foundation, making it simple and convenient to use. Attached Figure Description

It also includes a positioning bolt 14 and a positioning nut 15 for fixing the first side plate 2 and the second side plate 3. Two washers are fitted on the positioning bolt 14. The positioning bolt 14 passes through the first hole 12 and the second hole 13. The first hole 12 and the second hole 13 are both countersunk holes.

A second mesh 21 is provided on the inner side of the drying hole 20, and a third mesh 22 is provided on the outer side. The second mesh 21 and the third mesh 22 respectively cover the two ends of the drying hole 20.

[0045] A positioning ring 23 is fixedly provided on the top of the first top frame 4, and the projection of the positioning ring 23 in the vertical direction is located within the projection of the first top frame 4 in the vertical direction.

[0047] The inner wall of the second side plate 3 is provided with a plurality of embedded plates 25, the embedded plates 25 having threaded holes, and the embedded plates 25 having cable brackets 26 horizontally arranged on them.

[0048] Several moisture-proof board bodies 6 are arranged in parallel. One side of each moisture-proof board body 6 is provided with a mating groove, and the other side is provided with a mating strip that mates with the mating groove. Two adjacent moisture-proof board bodies 6 are connected by the mating strip and the mating groove. A first support groove 27 is provided on the inner side of the top of the first top frame 4. Both ends of all moisture-proof board bodies 6 overlap the inner wall of the first support groove 27, and the outer side of the moisture-proof board body 6 located at the edge overlaps the inner wall of the first support groove 27.

[0049] The second top frame 5 has a second support groove 28 on its inner side. Several manhole plates 7 are provided. Both ends of all manhole plates 7 overlap the inner wall of the second support groove 28, and the outer side of the manhole plates 7 located at the edge overlaps the inner wall of the second support groove 28.

[0050] This utility model provides a novel ring main unit foundation component. Firstly, the base plate 1, first top frame 4, second top frame 5, first side plate 2, second side plate 3, moisture-proof board 6, and manhole plate 7 are all manufactured (or purchased directly) at an external site. They are then transferred to the site where they are needed in parts and assembled on-site. During assembly, the base plate 1 is first transferred or hoisted (even with equipment, the lightweight and small size of the components reduces the requirements for hoisting machinery, making it easier to use and less demanding on the site) to the designated position. Then, the first side plate 2 and second side plate 3 are installed in their designated positions on the base plate 1. Next, the first top frame 4 and second top frame 5 are placed on top of the first side plate 2 and second side plate 3. Finally, the moisture-proof board 6 is placed in its designated position on the first top frame 4, and the manhole plate 7 is placed in its designated position on the second top frame 5. This forms a complete ring main unit foundation. In actual use, grouting or applying concrete to all joints is necessary to improve the foundation's waterproofing and structural strength. The through-hole 8 is used in conjunction with cable ducts, allowing cables to pass through the ring main unit foundation.

[0051] Since the components in the ring main unit foundation of this application are manufactured in the factory or purchased directly in the form of individual parts (such as the municipal manhole cover type manhole plate 7 and ALC moisture-proof board body 6), the quality is relatively controllable. Secondly, when transferring, transporting and assembling the components, the requirements for the site are lower and the actual operation is simpler because the components are lighter and smaller. At the same time, the requirements for the equipment during on-site assembly are also lower.

[0052] The moisture-proof board 6 is preferably made of lightweight concrete (standard part), which not only provides moisture protection and ensures the safety of the ring main unit, but also facilitates drilling for cable passage. Different ring main units require different types of holes, so the lightweight concrete material of the moisture-proof board 6 makes it easy for workers to drill on-site. Meanwhile, the first top frame 4 is higher than the second top frame 5, thus raising the ring main unit above the ground; however, the top of the second top frame 5 is almost flush with the ground, allowing manhole cover 7 to support passage. During maintenance, simply opening the manhole cover 7 allows for easy access to the ring main unit foundation, making it simple and convenient to use.

[0053] In the actual assembly process, firstly, the two first side plates 2 are placed in the two ends of the first slot 9 of the base plate 1. Then, the second side plate 3 is vertically placed into the corresponding position in the first slot 9, ensuring that the edges of the first side plates 2 and 3 are flush. Next, the positioning bolt 14 is taken, passed through the first hole 12, and the positioning nut 15 is inserted into the second hole 13 and threadedly connected to the positioning bolt 14. Thus, the positioning bolt 14 and the positioning nut 15 fix the first side plate 2 and the second side plate 3, forming a complete rectangular frame. Simultaneously, the gasket provides protection, preventing damage to the first side plates 2 and 3. Concrete will be subsequently injected into the first hole 12 and the second hole 13 to prevent rust and to prevent external water from seeping into the ring main unit foundation.

[0054] Next, the first top frame 4 and the second top frame 5 are vertically lowered, so that the tops of the first side plate 2 and the second side plate 3 are engaged in the second slot 10 or the third slot 11. At the same time, the temporary rod (not shown in the figure) is located in the temporary hole 16, which improves the relative position stability of the top frames of the first top frame 4 and the second top frame 5 with the first side plate 2 and the second side plate 3. Finally, the moisture-proof board 6 is placed in the first support groove 27, and the manhole plate 7 is placed in the second support groove 28, so that adjacent moisture-proof board 6 are interlocked by mating grooves and mating strips. The depth of the mating groove and the thickness of the mating strip are not large. Therefore, in actual operation, the moisture-proof board 6 can be placed into the first support groove 27 one by one, and then the moisture-proof board 6 can be moved horizontally. In this way, the gap between the outer side of the last moisture-proof board 6 and the first support groove 27 is relatively large, but all the moisture-proof board 6 can still cover the opening at the top of the entire top frame. No grouting is applied between the manhole plate 7 and the second support groove 28, which facilitates subsequent access to the foundation for maintenance. However, depending on the actual situation, adjacent manhole plates 7 can be tightly pressed against each other, and the manhole plate 7 can be tightly pressed against the inner wall of the second support groove 28 to reduce the entry of external water into the foundation; or waterproof strips or waterproof boards can be installed between adjacent manhole plates 7 and between the manhole plate 7 and the inner wall of the second support groove 28 to reduce the entry of external rainwater into the foundation.

[0055] After the base plate 1, first side plate 2, second side plate 3, first top frame 4, second top frame 5, moisture-proof board 6 (preferably ALC), and manhole plate 7 are all placed, cement mortar will be injected into the first slot 9, the second slot 10, the third slot 11, the connection between the first side plate 2 and the second side plate 3, between adjacent moisture-proof boards 6, between the first top frame 4 and the second top frame 5, and between the moisture-proof board 6 and the first support groove 27. Dry mortar should be used in the second slot 10 and the third slot 11 to prevent it from falling out. Finally, the bottom of the ring main unit is welded to the positioning ring 23 (preferably a U-shaped channel steel with its opening facing downwards), thus completing the connection between the ring main unit foundation and the ring main unit. The positioning ring 23 can be grounded through the grounding component 24.

[0056] The embedded plate 25 is pre-embedded within the second side plate 3, allowing for the subsequent connection of the cable bracket 26 to support the cables within the foundation. The connection between the embedded plate 25 and the cable bracket 26 can be achieved through welding or by threading bolts through the cable bracket 26 into the threaded holes. Furthermore, during the pre-embedding of the embedded plate 25, a support rod can be threaded into the threaded holes (this rod will detach from the embedded plate 25 after use). The support rod then supports the position of the embedded plate 25 before grouting, thus integrating the embedded plate 25 with the second side plate 3 and preventing mortar from entering the threaded holes.

[0057] In subsequent use, if water seeps into the foundation or drainage from the cable trenches on both sides of the foundation enters the foundation, the water can be collected in the sedimentation tank 17 and discharged outwards through the outlet 19. In practical use, it is preferable to connect a pipe to the outlet 19 to guide the water in the sedimentation tank 17 into the municipal pipeline. It is also preferable to install an automatically opening one-way valve at the outlet 19 to block moisture from the municipal pipeline. Simultaneously, the first mesh 18 prevents impurities from entering the pipeline outside the outlet 19, ensuring normal operation. Furthermore, the drying hole 20, the second mesh 21, and the third mesh 22 are all above ground level, allowing water in the foundation to evaporate through the drying hole 20, thus ensuring the foundation remains dry. The second mesh 21 and the third mesh 22 also prevent rodents and insects from entering the foundation, and the small opening at the inner end of the drying hole 20 also provides some barrier function. Furthermore, since the drying hole 20 is frustum-shaped, its bottom is sloping, which can better prevent external rainwater from flowing into the foundation.

[0058] In another embodiment, the drying hole 20 is inclined, with its top communicating with the interior of the foundation and its bottom communicating with the exterior.

[0059] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0060] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
