Description

An internal wiring arrangement structure for a prefabricated substation Technical Field

[0001] This invention belongs to the field of line organization technology, and in particular relates to an internal line organization structure for a box-type substation. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor / outdoor power distribution system that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme. It organically combines transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. Prefabricated substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering substations and becoming a new type of complete power distribution system.

[0003] Existing prefabricated substations have inadequate wiring systems, hindering reliable and rapid wiring connections. The resulting wiring is often loose, increasing the risk of safety accidents and complicating maintenance. Therefore, there is an urgent need to develop a new internal wiring organization structure for prefabricated substations to overcome these shortcomings in current applications. Summary of the Invention

[0004] The purpose of this invention is to provide an internal wiring arrangement structure for prefabricated substations, aiming to solve the problems of existing prefabricated substation wiring devices that are not conducive to reliable and rapid wiring connections, and the wiring after arrangement being relatively loose.

[0005] This invention is implemented as follows: an internal wiring organization structure for a prefabricated substation includes a wiring organization body fixed inside the prefabricated substation, and further includes: a support rod, the upper part of which is fixedly mounted; a movable rotating component is mounted on the support rod, which can slide and adjust along the support rod; a connecting frame is fixedly mounted on the movable rotating component, which also allows the connecting frame to rotate relative to the support rod; a hanging column is fixedly mounted on the side of the connecting frame away from the movable rotating component; a winding column is rotatably mounted on the hanging column for winding the wiring; a telescopic rod is slidably mounted on the end of the hanging column away from the connecting frame; a retaining wheel is mounted on the end of the telescopic rod away from the hanging column; an elastic element is sleeved on the telescopic rod for elastically supporting the retaining wheel; the retaining wheel can also elastically lock into the bottom of the wiring organization body.

[0006] A further technical solution includes a fixing bolt, a first rotating ring, a sleeve, and a second rotating ring. The sleeve is slidably fitted onto the support rod, and a fixing bolt is also provided in the middle of the sleeve. The fixing bolt is used to lock and fix the sleeve onto the support rod. The second rotating ring and the first rotating ring are rotatably installed at both ends of the sleeve, respectively. The connecting frame adopts a U-shaped structure, and the two ends of the connecting frame are fixedly connected to the second rotating ring and the first rotating ring, respectively.

[0007] In a further technical solution, the winding post and the hanging post are rotatably connected, the cross-section of the winding post is circular, and the winding post has a central arc-shaped concave structure.

[0008] A further technical solution includes a movable cavity at the upper part of the lifting column, a movable block slidably disposed within the movable cavity, a movable rod fixed to one side of the movable block, an opening for the movable rod to move on the side wall of the lifting column, and an installation ring cavity on the inner wall of the winding column corresponding to the lower part of the movable cavity, in which ratchet teeth are fixed; a rotating shaft is rotatably mounted at the bottom of the movable cavity, a stop pawl is fixed on the rotating shaft, a swing opening for the stop pawl to swing out on the side wall of the lifting column, a torsion spring is sleeved on the rotating shaft, one end of the torsion spring is fixedly connected to the stop pawl, and the other end of the torsion spring is fixedly connected to the bottom of the movable cavity, the torsion spring is used to make the stop pawl elastically abut against the ratchet teeth, a pull rope is also provided on the stop pawl, the pull rope passes through a guide ring fixed to the wall of the movable cavity, and the end of the pull rope away from the stop pawl is connected and fixed to the movable block.

[0009] In a further technical solution, when there is no external force, the movable rod is located at the lower end of the movable opening, the pull rope is in a taut state, and at this time the stop pawl elastically abuts against the ratchet teeth under the torsion of the torsion spring. The stop pawl also abuts against one side of the swing opening, so that the ratchet teeth can only rotate in one direction through the stop pawl.

[0010] In a further technical solution, the movable opening is an inverted L-shaped structure, and a groove for accommodating the movable rod is provided on the lower side of the horizontal part of the movable opening; when the movable rod is locked in the groove of the horizontal part of the movable opening, the movable block pulls the stop pawl and the ratchet teeth by pulling the rope, thereby releasing the unidirectional rotation restriction of the stop pawl on the winding post and the ratchet teeth as a whole.

[0011] In a further technical solution, multiple rotating components are circumferentially distributed at the end of the winding post. Each rotating component includes a rod and a ball head. One end of the rod is fixed to the winding post, and the other end of the rod is provided with a ball head.

[0012] A further technical solution is provided, wherein the lower part of the hanging column is provided with a telescopic cavity, and the telescopic rod slides into the telescopic cavity from the bottom of the hanging column. The upper end of the telescopic rod is also integrally formed with an anti-detachment flange, which is slidably connected to the telescopic cavity. The anti-detachment wheel component includes an inverted U-shaped wheel frame, a drag-reducing wheel, and a wheel axle. The inverted U-shaped wheel frame is fixed to the lower end of the telescopic rod, and a wheel axle is rotatably mounted on the inverted U-shaped wheel frame. The drag-reducing wheel is fixed on the wheel axle.

[0013] In a further technical solution, the cable management body has a U-shaped structure, and multiple fixing blocks are integrally formed on the upper and lower rear sides of the cable management body, with fixing holes provided on the fixing blocks; an installation port is provided on the upper part of the cable management body, and the support rod is located in the installation port, with both ends of the support rod being fixedly connected to the cable management body at both ends of the installation port.

[0014] A further technical solution is provided in which a groove is provided at the bottom of the cable management body, the length of the groove is the same as the length of the support rod, the groove is a central arc-shaped concave structure, the connection between the groove and the inner bottom of the cable management body is rounded, and the front bottom of the cable management body is rounded; when the drag-reducing wheel of the anti-fixing wheel is inserted into the groove, the winding post is parallel to the rear side wall of the cable management body.

[0015] This invention provides an internal wiring organization structure for a prefabricated substation. By limiting the movement of a rotating component, it allows for sliding adjustment along a support rod, enabling adaptive adjustment based on the required wiring position and type, thus better matching actual needs. The limiting rotating component also allows the connecting frame to rotate relative to the support rod, and the retaining wheel and telescopic rod to elastically extend and retract. This allows the winding post to be in a movable state, with its lower end separated from the wiring main body, facilitating wiring winding onto the winding post. This is particularly suitable for situations with narrow spaces and many winding posts nearby. After winding, the retaining wheel is elastically locked at the bottom of the wiring main body, making it convenient and quick. Furthermore, limiting the winding post to only rotate unidirectionally around the hanging column facilitates secure wiring, preventing it from becoming loose, ensuring reliable application, and facilitating maintenance.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] As shown in Figures 1-3, an embodiment of the present invention provides an internal wiring organization structure for a prefabricated substation, including a wiring organization body 7 fixed inside the prefabricated substation, and further comprising:

[0027] A support rod 3 is fixedly installed on the upper part of the cable management body 7. A movable rotating component 6 is installed on the support rod 3. The movable rotating component 6 can slide and adjust along the support rod 3. A connecting frame 14 is fixedly installed on the movable rotating component 6. The movable rotating component 6 is also used to enable the connecting frame 14 to rotate relative to the support rod 3. A hanging column 20 is fixedly installed on the side of the connecting frame 14 away from the movable rotating component 6. A winding column 12 is unidirectionally mounted on the hanging column 20. The winding column 12 is used for winding the cable. A telescopic rod 11 is also slidably installed on the end of the hanging column 20 away from the connecting frame 14. A retaining wheel 9 is installed on the end of the telescopic rod 11 away from the hanging column 20. An elastic element 10 is also sleeved on the telescopic rod 11 for elastic support of the retaining wheel 9. The elastic element 10 is preferably a spring. The retaining wheel 9 can also be elastically locked at the bottom of the cable management body 7.

[0028] In this embodiment of the invention, the movable rotating member 6 can slide and adjust along the support rod 3, allowing for adaptive adjustment according to the required winding position and model of the wire, thus better matching actual needs. The movable rotating member 6 also allows the connecting frame 14 to rotate relative to the support rod 3, and the retaining wheel 9 and telescopic rod 11 to elastically extend and retract, enabling the winding post 12 to be in a movable state with its lower end separated from the wire management body 7. This facilitates winding the wire onto the winding post 12, especially suitable for narrow spaces with many winding posts 12 around it. After winding, the retaining wheel 9 can be elastically locked at the bottom of the wire management body 7, making it convenient and quick. Furthermore, limiting the winding post 12 to rotate only unidirectionally around the hanging column 20 facilitates wire tightening, preventing the wire from being loose, ensuring reliable application, and facilitating maintenance.

[0029] As shown in Figures 3 and 4, in a preferred embodiment of the present invention, multiple movable rotating components 6 are preferably installed on the support rod 3. Each movable rotating component 6 includes a fixing bolt 5, a first rotating ring 21, a sleeve 22, and a second rotating ring 23. The sleeve 22 is slidably fitted onto the support rod 3, and a fixing bolt 5 is also provided in the middle of the sleeve 22. The fixing bolt 5 is used to lock the sleeve 22 onto the support rod 3. The second rotating ring 23 and the first rotating ring 21 are rotatably installed at both ends of the sleeve 22, respectively. The connecting frame 14 adopts a U-shaped structure, and both ends of the connecting frame 14 are fixedly connected to the second rotating ring 23 and the first rotating ring 21, respectively. Through this limitation, the entire assembly consisting of the connecting frame 14, the second rotating ring 23, and the first rotating ring 21 can always rotate around the sleeve 22. The position of the sleeve 22 on the support rod 3 can be arbitrarily adjusted by the fixing bolt 5, and then locked, which is convenient and quick.

[0030] As shown in Figures 1-3 and 5-7, in a preferred embodiment of the present invention, the winding post 12 and the hanging post 20 are rotatably connected. The cross-section of the winding post 12 is circular, and the winding post 12 has a concave arc structure in the middle, which allows the wire to gather towards the middle of the winding post 12 and improves the reliability of wire arrangement, preventing the wire from falling off to both ends of the winding post 12. The surface of the winding post 12 is also preferably provided with an anti-slip layer (not shown) to improve the winding effect.

[0031] The upper part of the hanging column 20 has a movable cavity 24, in which a movable block 25 is slidably disposed. A movable rod 16 is fixed to one side of the movable block 25. A movable opening 15 for the movable rod 16 to move is provided on the side wall of the hanging column 20. A mounting ring cavity 31 is provided on the inner wall of the winding column 12 corresponding to the lower part of the movable cavity 24. A ratchet tooth 30 is fixed in the mounting ring cavity 31. The ratchet tooth 30 is similar to the tooth shape of a ratchet and is not limited. A rotating shaft 34 is rotatably mounted at the bottom of the movable cavity 24. A stop pawl 32 is fixed on the rotating shaft 34. A swing opening 33 for the stop pawl 32 to swing out is provided on the side wall of the hanging column 20. A torsion spring 35 is sleeved on the rotating shaft 34. One end of the torsion spring 35 is fixedly connected to the stop pawl 32, and the other end of the torsion spring 35 is fixedly connected to the bottom of the movable cavity 24. The torsion spring 35 is used to make the stop pawl 32 spring back. The stop pawl 32 is abutted against the ratchet tooth 30. A pull rope 28 is also provided on the stop pawl 32. The pull rope 28 passes through a guide ring 29 fixed to the wall of the movable cavity 24, and the guide ring 29 guides the pull rope 28. The end of the pull rope 28 away from the stop pawl 32 is connected and fixed to the movable block 25. When there is no external force, the movable rod 16 is located at the lower end of the movable opening 15, the pull rope 28 is in a taut state, and at this time, the stop pawl 32 elastically abuts against the ratchet tooth 30 under the torque of the torsion spring 35. The stop pawl 32 also abuts against one side of the swing opening 33. The stop pawl 32 allows the ratchet tooth 30 to rotate only in one direction, as shown in Figure 7. The entire structure consisting of the winding post 12 and the ratchet tooth 30 can rotate clockwise, but cannot rotate counterclockwise due to the restriction of the stop pawl 32. This limitation also restricts the stop pawl 32 to abutting against one side of the swing opening 33, improving the reliability of the stop pawl 32.

[0032] In one embodiment, the movable opening 15 is preferably an inverted L-shaped structure, and a groove for accommodating the movable rod 16 is provided on the lower side of the horizontal portion of the movable opening 15. When the movable rod 16 is engaged in the groove of the horizontal portion of the movable opening 15, the movable block 25 pulls the stop pawl 32 and the ratchet tooth 30 through the pull rope 28, thereby releasing the unidirectional rotation restriction of the stop pawl 32 on the winding post 12 and the ratchet tooth 30 as a whole, as shown by the dotted line in Figure 7. In addition, when releasing the restriction of the stop pawl 32 on the ratchet tooth 30, the winding post 12 and the ratchet tooth 30 need to rotate at a certain angle. This angle can be satisfied by loose winding between the wires, and is not limited or described in detail.

[0033] In one embodiment, to facilitate rotation of the winding post 12, a plurality of rotating components 13 are circumferentially distributed at the end of the winding post 12. Each rotating component 13 includes a rod and a ball head. One end of the rod is fixed to the winding post 12, and the other end of the rod is provided with a ball head. The rotating components 13 facilitate reliable rotation of the winding post 12.

[0034] In this embodiment of the invention, when winding the wire, pay attention to the winding direction of the wire on the winding post 12. After winding, the wire can be properly tightened by rotating the winding post 12 in one direction, which is reliable. When it is necessary to loosen the wire, the winding post 12 will be released from the one-way rotation state when the movable rod 16 is pulled into the horizontal groove of the movable opening 15, which is conducive to loosening the wire and finally removing the wire, which is convenient and reliable.

[0035] As shown in Figures 2 and 5, in a preferred embodiment of the present invention, the lower part of the hanging column 20 is provided with a telescopic cavity 26, and the telescopic rod 11 slides into the telescopic cavity 26 from the bottom of the hanging column 20. The upper end of the telescopic rod 11 is also integrally formed with an anti-detachment flange 27, which is slidably connected to the telescopic cavity 26. By setting the anti-detachment flange 27, the stability of the telescopic rod 11's extension and retraction can be improved, and it can play an anti-detachment role.

[0036] The abutment wheel 9 includes an inverted U-shaped wheel frame 17, a drag-reducing wheel 18, and a wheel axle 19. The inverted U-shaped wheel frame 17 is fixed to the lower end of the telescopic rod 11. A wheel axle 19 is rotatably mounted on the inverted U-shaped wheel frame 17. The drag-reducing wheel 18 is fixed on the wheel axle 19. The inverted U-shaped wheel frame 17, the drag-reducing wheel 18, and the wheel axle 19 form a support wheel structure.

[0037] As shown in Figure 1, in a preferred embodiment of the present invention, the cable management body 7 is preferably a U-shaped structure. The upper and lower rear sides of the cable management body 7 are integrally formed with multiple fixing blocks 1. Fixing holes 2 are provided on the fixing blocks 1. By limiting the fixing blocks 1 and fixing holes 2, it is convenient to install and fix the cable management body 7 inside the box-type substation, such as fixing it to its inner wall.

[0038] The upper part of the cable management body 7 is provided with an installation port 4, and the support rod 3 is located in the installation port 4. The two ends of the support rod 3 are respectively fixedly connected to the cable management body 7 at both ends of the installation port 4, thereby improving the rationality of the installation.

[0039] The bottom of the cable management body 7 is provided with a groove 8, the length of which is the same as the length of the support rod 3. The groove 8 can accommodate a wide range of adjustment and movement of the retaining wheel 9. The groove 8 is preferably a central arc-shaped concave structure. The connection between the groove 8 and the inner bottom of the cable management body 7 is rounded, and the front bottom of the cable management body 7 is also rounded to improve the smoothness of the retaining wheel 9 when it is inserted into the groove 8. When the drag-reducing wheel 18 of the retaining wheel 9 is inserted into the groove 8, the winding post 12 is parallel to the rear side wall of the cable management body 7, resulting in good application effect.

[0040] In addition, there are no specific limitations on the model, size, material, etc. of each component, which can be flexibly set in actual application.

[0041] The above embodiments of the present invention provide an internal wiring organization structure for a prefabricated substation, which is easy to use and adjust. When winding the wiring, one end of the winding post 12 can be separated from the wiring body 7, facilitating winding. After winding, it can be repositioned onto the wiring body 7, making it convenient and quick. In addition, it also has unidirectional tightening and loosening functions, improving the reliability and convenience of application and achieving convenient maintenance.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
