Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a modular base plate structure and power distribution cabinet. Background Technology

[0002] Currently, the conventional cable entry and exit structure of power distribution cabinets is a pre-designed openable base plate. This requires secondary processing on-site, such as cutting and grinding the cabinet, or the base plate already has an opening that can be directly removed with a cover plate. All of these are relatively large openings requiring additional sealing, such as filling with sealant or fireproof putty. In environments with stringent sealing requirements, it is necessary to improve the reliability of the opening seal and avoid large gaps at the cable locations. Customized sealing structures are used in these cases. For example, Chinese Patent 202420975802.3 discloses a cable entry and exit sealing structure for a power distribution cabinet, including a power distribution cabinet body. A sealing device is provided on one side of the power distribution cabinet body. The sealing device includes two mounting brackets. A mounting groove is formed on one side of the power distribution cabinet body. The two mounting brackets are respectively engaged in the mounting groove. Several evenly distributed slots are formed on the side of the two mounting brackets that are close to each other. The cable passes through and is engaged in the through hole formed by the two slots.

[0003] For the aforementioned existing technologies, the cables of the distribution cabinet will use different specifications and sizes (outer diameters) due to their different power distribution functions. It is also necessary to select the corresponding number of cables according to the actual situation. The above fixed number of holes requires the number of cables and the outer diameter of the cables to match in order to form a seal, and its adaptability and adjustability are relatively weak. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a modular base plate structure and power distribution cabinet to solve the technical problem that the existing power distribution cabinet wiring structure has weak adaptability and adjustability under changes in the number and size of cables.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a modular base plate structure, comprising: The plate has a series of mounting holes arranged in an array. A sleeve assembly includes a connecting cylinder, an elastic sealing sleeve, and a clamping assembly. The connecting cylinder is detachably connected to a corresponding mounting hole. The elastic sealing sleeve is used to elastically wrap around the outside of a cable. The clamping assembly has an openable and closable clamping end for clamping and positioning the cable passing through the elastic sealing sleeve from both sides. A sealing assembly, which is connected to the plate, has a sealing end corresponding to each of the mounting holes, wherein the sealing end has an insertion state that is inserted into the corresponding mounting hole and an open state that is disengaged from the corresponding mounting hole.

[0006] In some embodiments, the plate body includes a substrate and an array of perforated plates. An opening is provided on the substrate, and the array of perforated plates is detachably mounted on the substrate and covers the opening. The mounting holes are provided on the array of perforated plates.

[0007] In some embodiments, the connecting cylinder is threadedly connected to the corresponding mounting hole.

[0008] In some embodiments, the cross-sectional shape of the resilient sealing sleeve is frustoconical.

[0009] In some embodiments, the clamping assembly includes a connecting frame, a bidirectional screw, and clamping plates. The bidirectional screw has two threads in opposite directions. The connecting frame is disposed on the connecting cylinder, and the bidirectional screw is rotatably connected to the connecting frame. The two clamping plates are respectively threaded to the threads at both ends of the bidirectional screw.

[0010] In some embodiments, the clamping plate is provided with two symmetrically distributed cylindrical rods.

[0011] In some embodiments, the sealing assembly includes rubber strips, the number of which corresponds to the number of array rows of the mounting holes, and rubber sealing caps connected to the rubber strips corresponding to the number of mounting holes in a row, the rubber sealing caps being used to close or open the mounting holes.

[0012] In some embodiments, the connecting cylinder includes a cylinder body and an annular cover. The top of the cylinder body is provided with an annular flange, and the annular cover is threaded to the outside of the annular flange and forms a limiting groove for pressing the elastic sealing sleeve.

[0013] In some embodiments, a limiting block is provided at the bottom of the annular flange for being embedded in the elastic sealing sleeve.

[0014] Secondly, this utility model also provides a power distribution cabinet, including a modular base plate structure as described in any of the above.

[0015] Compared with the prior art, the modular base plate structure provided by this utility model can select the number of installation holes to be used according to the actual situation by arranging multiple installation holes on the plate. The installation holes that are not used can be closed by the sealing component, while the installation holes are equipped with installation sleeves. The elastic sealing sleeves can be flexibly adapted to the outer diameter of multiple sizes of cables.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of weak adaptability and adjustability of the wiring structure in power distribution cabinets under changes in the number and size of cables, this utility model provides a modular base plate structure. This structure allows for the selection of the number of active mounting holes based on actual conditions, provided multiple mounting holes are arranged on the plate. Unactive mounting holes can be sealed by a hole-sealing component, while active mounting holes are fitted with mounting sleeves. These elastic sealing sleeves can flexibly adapt to various cable outer diameters. Combined with clamping components, the adjusted cables can be clamped, preventing loosening or damage to the cable connections within the cabinet due to pulling, thus improving the reliability of cable installation and connections.

[0020] It should be noted that the modular base plate structure described in this utility model is used for, but not limited to, the base plate position of the power distribution cabinet. For ease of explanation, this utility model only uses the installation of the modular base plate structure in the base plate position of the power distribution cabinet as an example. The principle of using the modular base plate structure for wiring in the side walls or top plates of other types of equipment is essentially the same as the principle of using it in the base plate position of the power distribution cabinet, and will not be described in detail here.

[0021] Please see Figure 1-4 This utility model provides a modular base plate structure, which includes a plate body 1, a sleeve 2, and a sealing assembly 3. The plate body 1 has a plurality of mounting holes 101 arranged in a double-row array. The sleeve 2 includes a connecting cylinder 21, an elastic sealing sleeve 22, and a clamping assembly 23. The connecting cylinder 21 is detachably connected to the corresponding mounting hole 101. The appropriate number of connecting cylinders 21 can be selected based on the number of cables to be threaded. The elastic sealing sleeve 22 is used to elastically wrap around the outside of the cable. The clamping assembly 23, which is adapted to cables of different outer diameters, has an openable clamping end for clamping and positioning the cable passing through the elastic sealing sleeve 22 from both sides. The sealing assembly 3 is connected to the plate 1 and has a sealing end corresponding to each of the mounting holes 101. The sealing end has an inserted state that is inserted into the corresponding mounting hole 101 and an open state that is detached from the corresponding mounting hole 101. The sealing end can be opened as needed for cables to pass through into the distribution cabinet, while the mounting holes 101 that do not need to be opened can remain in the inserted state for sealing.

[0022] In use, the base plate structure has a modular plate body 1, sleeve 2 and sealing assembly 3, which can be adapted to different specifications and quantities of cables to be pulled into the distribution cabinet according to actual needs. While meeting the quantity requirements of the cables to be pulled in, it also meets the sealing requirements of cables of different specifications and sizes.

[0023] Understandably, the maximum outer diameter that the elastic sealing sleeve 22 can expand and wrap is the maximum size specification of commonly used cables, while the range of elastic deformation is the range of the outer diameter of the cables that can be adapted. In addition, if the cable size exceeds the maximum and minimum range, an elastic sealing sleeve of another size can be installed on the connecting sleeve 21 for use.

[0024] In one embodiment, please refer to Figure 2 To facilitate production and assembly, the plate body 1 includes a base plate 11 and an array perforated plate 12. The base plate 11 has an opening 102, which provides a sufficiently large access space. The array perforated plate 12 is detachably mounted on the base plate 11 and covers the opening 102. The mounting holes 101 are formed on the array perforated plate 12. Since the specifications and quantity of cables may vary under different application scenarios, the array perforated plate 12 with different numbers and diameters of mounting holes 101 can be selected and used according to actual needs in the separate structure of the opening 102 and the array perforated plate 12.

[0025] Understandably, during manufacturing, array perforated plates 12 with three rows of multi-column mounting holes 101 or other array perforated plates 12 with different array distributions can be manufactured, and the inner diameter of the mounting holes 101 on the perforated plate can also have different specifications, which are not limited here.

[0026] In one embodiment, please refer to Figure 1 and Figure 2 The connecting cylinder 21 is threadedly connected to the corresponding mounting hole 101, which facilitates installation and disassembly. The outer side of the connecting cylinder 21 is provided with a sealing ring that abuts against the top of the mounting hole 101 for sealing.

[0027] Furthermore, the cross-sectional shape of the elastic sealing sleeve 22 is frustoconical, and it is a sealing sleeve that decreases from bottom to top. Its upper half is used for elastic deformation to fit the outer periphery of the cable.

[0028] In one embodiment, please refer to Figure 3 To facilitate cable clamping, the clamping assembly 23 includes a connecting frame 231, a bidirectional screw 232, and clamping plates 233. The bidirectional screw 232 has two threads in opposite directions. The connecting frame 231 is mounted on the connecting cylinder 21, and the bidirectional screw 232 is rotatably connected to the connecting frame 231. The two clamping plates 233 are threaded to the threads at both ends of the bidirectional screw 232. By rotating the bidirectional screw 232, the two clamping plates 233 can be moved relative to or away from each other to clamp the cable, thereby achieving a positional fixation and preventing the cable from moving axially.

[0029] Furthermore, to avoid damage to the cable clamping, the clamping plate 233 is provided with two symmetrically distributed cylindrical rods 234. The two clamping plates 233 form a clamping pattern of four cylinders, forming a four-point clamping, which can be adapted to clamping cables of different sizes. In addition, the cylindrical outer periphery is less likely to cause damage to the cable.

[0030] In one embodiment, please refer to Figure 2 To facilitate the integrated sealing and opening of the mounting holes 101, the sealing assembly 3 includes rubber strips 31, the number of which corresponds to the number of array rows of the mounting holes 101. Each rubber strip 31 is connected to a rubber sealing cap 32 corresponding to the number of mounting holes 101 in a row. The rubber sealing cap 32 is used to cover or open the mounting holes 101. The rubber strips 31 are directly fixed to the array hole plate 12. By simply flipping up the corresponding rubber sealing cap 32, the mounting hole 101 at the corresponding position can be opened, which is convenient for operation and use.

[0031] Understandably, the rubber strip 31 and the rubber sealing cap 32 are not only low-cost and insulating, but also elastic, effectively sealing the mounting hole 101 and easy to flip up and cover.

[0032] In one embodiment, please refer to Figure 3 and Figure 4 To facilitate the replacement of the elastic sealing sleeve 22, the connecting cylinder 21 includes a cylinder body 211 and an annular cover 212. The top of the cylinder body 211 is provided with an annular flange 213. The annular cover 212 is threaded to the outside of the annular flange 213 and forms a limiting groove 214 for pressing the elastic sealing sleeve 22. By moving the annular cover 212 down, the elastic sealing sleeve 22 in the limiting groove 214 can be pressed tightly to form a detachable connection. When it is necessary to replace the elastic sealing sleeve 22, the annular cover 212 can be removed.

[0033] The connecting bracket 231 is fixedly connected to the annular cover 212.

[0034] Furthermore, the bottom of the annular flange 213 is provided with a limiting block 215, which is used to be embedded in the elastic sealing sleeve 22. By the limiting block 215 being embedded in the elastic sealing sleeve 22, the reliability of the pressing is improved, and the elastic sealing sleeve 22 is prevented from being pulled apart.

[0035] This utility model also provides a power distribution cabinet, including a modular base plate structure as described in any one of the claims, used as the base plate of the cabinet, for cables to pass through from bottom to top into the interior of the power distribution cabinet.

[0036] Understandably, modular base plates are mainly used for assembling the base plates of distribution cabinets. However, when it is necessary to run cables through the side walls or top of the distribution cabinet, the above structure can also be used on the side plates or top plates. This is not the only limitation.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: When it is necessary to install a cable, first select the preferred position of the mounting hole 101 according to the position of the cable, lift the rubber sealing cover 32 on it, and then install the sleeve 2. Connect the connecting cylinder 21 to the mounting hole 101 by thread. Then, pass the cable through the connecting cylinder 21 and the elastic sealing sleeve 22 from bottom to top, and install and fix the cable in the cabinet. After adjusting the position of the cable, rotate the bidirectional screw 232 so that the four cylindrical rods 234 on the two clamping plates 233 clamp and position the cable. This completes the cable threading, sealing and fastening operation. It is convenient to adapt to the installation operation of different quantities and sizes of cables according to actual needs and has a sealing effect at the penetration point. The adaptability and adjustability are both high.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
