Abstract
Description
Technical Field
[0001] This application relates to the field of MPP cable protection pipe technology, and in particular to an MPP cable protection pipe structure with overload protection function. Background Technology
[0002] With the acceleration of urbanization and the continuous growth of electricity demand, the scale of urban power grid construction and renovation is expanding daily. Traditional overhead cables are gradually being replaced by underground cables due to safety hazards and aesthetic concerns. As an important supporting facility for underground cable laying, the demand for MPP cable protection pipes is also rapidly increasing, providing a broad market space for their development.
[0003] In the existing technology, a certain number of MPP cable protection pipes are generally stored in a stacked manner. To facilitate retrieval and management, MPP cable protection pipes are usually stacked in parallel or cross-arrangement.
[0004] Regarding the aforementioned technologies, the inventors believe that prolonged stacking and placement can easily lead to deformation of the MPP cable protection pipe, affecting its performance. Utility Model Content
[0005] The purpose of this application is to provide an MPP cable protection pipe structure with stacking protection function to improve the problem that MPP cable protection pipes are prone to deformation due to long-term stacking.
[0006] This application provides a structure for MPP cable protection pipe with overload protection function, which adopts the following technical solution:
[0007] An MPP cable protection pipe structure with overload protection function includes an outer sheath frame. The outer sheath frame includes an upper sheath frame and a lower sheath frame, both of which are semi-circular. The upper sheath frame has plug-in plates at both ends, and the lower sheath frame has slots corresponding to the plug-in plates. The upper and lower sheath frames can be spliced together to form a circular frame. The cable pipe is inserted into the circular frame formed by the outer sheath frame. The outer sheath frame has several sections arranged sequentially along the length of the cable pipe on the outer side wall of the cable pipe.
[0008] By adopting the above technical solution, the outer wall of the cable conduit is protected by an outer protective frame, which avoids friction between the cable conduit and the ground during the stacking of the cable conduit, thus preventing scratches on the cable conduit. By sequentially setting several outer protective frames along the length of the cable conduit on its outer wall, the stress of the cable conduit is evenly distributed, reducing the impact of the stacking force on the deformation of the cable conduit. The upper and lower protective frames are fixedly connected by a plug-in plate with a plug slot, which facilitates the installation and disassembly of the outer protective frames and makes it easy to remove the outer protective frames when the cable conduit is needed, thus improving efficiency.
[0009] Optionally, the inner wall of the slot is provided with a fastening elastic pad.
[0010] By adopting the above technical solution, and by setting a fastening elastic element on the inner wall of the slot, when the plug plate is inserted into the slot, the fastening elastic element and the plug plate fit tightly together, increasing the friction, enhancing the insertion stability of the upper and lower protective frames, and improving the protective effect of the outer protective frame.
[0011] Optionally, the outer protective frame has several fixing holes on both sides of its circumference, and a connecting rod is provided in the fixing hole between two adjacent outer protective frames located on the outer side wall of the cable pipe.
[0012] By adopting the above technical solution, and by setting connecting rods to connect each outer sheath, the integrity of the outer sheath is enhanced, which helps to limit the gap between each outer sheath and keep the stress on each section of the cable pipe similar; the connecting rods have a certain blocking and protective effect, which helps to protect the cable pipe.
[0013] Optionally, both the upper and lower protective frames are fitted with elastic fasteners that fit against their respective inner sidewalls.
[0014] By adopting the above technical solution, the friction between the outer frame and the cable pipe is enhanced when the cable pipe is fixed in the outer frame by setting elastic fasteners, which helps to prevent the outer frame from sliding and enhances the stability of the outer frame; at the same time, the elastic fasteners help to protect the cable pipe and prevent the outer frame from scratching the cable pipe.
[0015] Optionally, an inner support plate is provided inside the cable conduit corresponding to the outer protective frame, and the outer side wall of the inner support plate is fitted to the inner side wall of the cable conduit.
[0016] By adopting the above technical solution, and by setting an inner support plate corresponding to the outer protective frame to support the inside of the cable pipe, it helps to fix the position of the cable pipe wall in conjunction with the outer protective frame, enhances the compressive strength of the cable pipe, helps the cable pipe resist the force that causes it to deform, and maintains the shape of the cable pipe.
[0017] Optionally, the inner support plate is provided with a number of metal blocks around its circumference, and the upper and lower protective frames are each provided with magnetic components attached to their respective inner sidewalls.
[0018] By adopting the above technical solution, the magnetic components used to attract metal blocks help determine the installation position of the inner support plate, and help the inner support plate work with the outer protective frame to support and fix the cable pipe.
[0019] Optionally, the outer circumference of the inner support plate is provided with several elastic pads.
[0020] By adopting the above technical solution, the inner support plate is made to fit tightly against the inner wall of the cable pipe by setting an elastic pad, which enhances the support capacity of the support plate. At the same time, the elastic pad helps to protect the inner wall of the cable pipe and reduce the possibility of scratching the inner wall of the cable pipe when moving the inner support plate.
[0021] Optionally, the inner support plate has a through groove in the center, and the inner support plate is provided with a support frame that is fixed to the inner side wall of the through groove.
[0022] By adopting the above technical solutions, the weight of the inner support plate is reduced by opening through slots, which facilitates the movement of the inner support plate and reduces the deformation effect of the inner support plate on the cable pipe. The structural stability of the inner support plate is improved by setting up a support frame, which helps to stabilize the supporting force of the inner support plate.
[0023] In summary, this application includes at least one of the following beneficial technical effects of an MPP cable protection pipe structure with overburden protection function:
[0024] 1. By setting an outer protective frame to protect the outer wall of the cable conduit, friction between the cable conduit and the ground is avoided during the stacking of the cable conduit, preventing scratches on the cable conduit; by setting several outer protective frames along the length of the cable conduit on the outer wall of the cable conduit, the stress of the cable conduit is evenly distributed, reducing the impact of the stacking force on the deformation of the cable conduit; by setting a plug-in plate and plug-in slot to fix the upper and lower protective frames, the installation and removal of the outer protective frames are convenient, and the removal of the outer protective frames when the cable conduit is needed is convenient, improving efficiency;
[0025] 2. By setting a fastening elastic element on the inner wall of the slot, when the plug plate is inserted into the slot, the fastening elastic element fits tightly with the plug plate, increasing the friction, enhancing the insertion stability of the upper and lower protective frames, and improving the protective effect of the outer protective frame.
[0026] 3. By setting an inner support plate in the corresponding outer frame, the cable conduit is supported inside. This helps to fix the position of the cable conduit wall in conjunction with the outer frame, enhances the cable conduit's compressive strength, helps the cable conduit resist the forces that cause deformation, and maintains the shape of the cable conduit.

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail below.
[0031] A structure for an MPP cable protection pipe with overburden protection function, as shown in the reference. Figure 1 , Figure 2 The system includes an outer protective frame 1, which comprises an upper protective frame 11 and a lower protective frame 12, both of which are semi-circular. The upper protective frame 11 has insertion plates 111 at both ends, and the lower protective frame has slots 121 corresponding to the insertion plates 111. A fastening elastic pad 1211, made of rubber, is installed on the inner wall of the slot 121 and is fixed in place within the slot 121 by adhesive material. The upper and lower protective frames 11 and 12 can be assembled into a circular frame. The cable conduit 9 is inserted into the circular frame formed by the outer protective frame 1. Several outer protective frames 1 are sequentially arranged along the length of the cable conduit 9 on the outer wall of the outer side of the outer protective frame 1. The number of outer protective frames 1 is not fixed, and is set based on reducing the stress of the cable pipe 9. In this embodiment, three are preferred, located at both ends and the center of the cable pipe 9 respectively. Several fixing holes 2 are opened on both sides of the outer protective frame 1. The number of fixing holes 2 is not fixed, and can be two, three, four, five or more. In this embodiment, the number of fixing holes 2 is four. A connecting rod 3 is provided between two adjacent outer protective frames 1 on the outer side wall of the cable pipe 9 and the fixing holes 2 are inserted. The length of the connecting rod 3 can be adjusted by replacing the connecting rod 3. The length adjustment of the connecting rod 3 depends on the length of the cable pipe 9 and the number of outer protective frames 1 used.
[0032] Reference Figure 1 An inner support plate 5 is provided inside the cable conduit 9 corresponding to the outer protective frame 1. The number of inner support plates 5 is the same as the number of outer protective frames 1. The outer side wall of the inner support plate 5 is attached to the inner side wall of the cable conduit 9. A through groove 52 is opened in the center of the inner support plate 5. The inner support plate 5 is provided with a support frame 8 fixed to the inner side wall of the through groove 52. In this embodiment, the support frame 8 is formed by two rods connected in one piece at the center. The two ends of the two rods are integrally connected and fixed to the inner side wall of the through groove 52.
[0033] Reference Figure 1 The inner support plate 5 has a groove around its circumference, and several metal blocks 51 are arranged in the groove. The number of metal blocks 51 is variable. In this embodiment, the metal blocks 51 are preferably made of iron, and four blocks are arranged. The metal blocks 51 are glued and fixed to the inner support plate 5. Several elastic pads 7 are arranged around the outer circumference of the inner support plate 5. The elastic pads 7 are made of rubber, and the number of elastic pads 7 is the same as that of the metal blocks 51. The elastic pads 7 are fixed between two adjacent metal blocks 51 by countersunk bolts, without covering the metal blocks 51. (Refer to...) Figure 2 Both the upper guard frame 11 and the lower guard frame 12 are fitted with elastic fasteners 4 attached to their respective inner walls. The elastic fasteners are made of rubber. Both the upper guard frame 11 and the lower guard frame 12 are fitted with magnetic fasteners 6 attached to their respective inner walls. Specifically, the elastic fasteners 4 are provided with two fasteners 4, which are fixed by countersunk bolts. The magnetic fasteners 6 are magnets, which are embedded between the two elastic fasteners 4 with glue.
[0034] The implementation principle of this application embodiment is as follows:
[0035] In actual use, the upper protective frame 11 and the lower protective frame 12 are inserted and fixed to the outer wall of the cable pipe 9, and are arranged sequentially along the length of the cable pipe 9. The outer protective frame 1 is connected by inserting the connecting rod 3 into the fixing holes 2 of two adjacent outer frames. The same number of inner support plates 5 as the outer protective frames 1 are placed into the cable pipe 9. The position of the inner support plate 5 is roughly determined by the magnetic attraction of the magnetic component 6 to the metal block 51, ensuring that the inner support plate 5 corresponds one-to-one with the outer protective frame 1. This helps to protect the MPP cable protection pipe and reduce the impact of long-term stacking on the deformation of the MPP cable protection pipe.
[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
