Description

Technical Field

[0001] This utility model relates to the field of power supply engineering technology, specifically to a pipeline structure for power supply system installation engineering. Background Technology

[0002] In power supply system installation projects, pipelines are used to protect power transmission lines such as cables and wires, playing an important role in preventing line damage, avoiding external interference, and fixing the route of the lines.

[0003] The existing patent document CN221885965U discloses a power pipe for easy maintenance in power engineering. Compared with existing devices, this power pipe for easy maintenance allows the main pipe and connecting pipe to be separated simply by manually prying open quick clamps during subsequent maintenance or repair of the pipe, through the cooperation between the various parts of the installation mechanism. This reduces the difficulty of operation and the operation time when using the pipe, and is conducive to improving the performance of the power pipe.

[0004] However, the existing power supply system installation pipeline structure is not conducive to resisting electromagnetic vibration during use. The existing pipeline structure is relatively simple. When the current in the power supply line changes and the cable generates electromagnetic vibration, these vibrations are directly transmitted to the pipeline wall. The pipeline structure itself does not have the function of energy absorption. The vibration energy cannot be dissipated in time and can only be continuously transmitted and accumulated in the pipeline and cable system, so that the vibration persists and intensifies. This will accelerate the wear of the cable sheath, reduce the insulation performance, and even cause the line connection to loosen, increasing the risk of short circuits and other faults, seriously affecting the stability and reliability of the power supply system.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a pipeline structure for power supply system installation engineering, including a lower half pipeline 1, an upper half pipeline 2 is hinged to one side of the lower half pipeline 1 by a hinge, and the upper half pipeline 2 and the lower half pipeline 1 form a closed cylindrical pipeline structure.

[0028] The lower half of the pipe 1 and the upper half of the pipe 2 are equipped with shock-absorbing springs 3. One end of the shock-absorbing spring 3 is connected to a support plate 4. A shock-absorbing rubber pad 5 is provided on the side of the support plate 4 away from the shock-absorbing spring 3.

[0029] When the cable generates electromagnetic vibration due to changes in current, the vibration is first transmitted to the damping rubber pad 5. The damping rubber pad 5 has certain elasticity and damping characteristics, which can absorb and buffer part of the vibration energy and reduce the transmission of vibration. The remaining vibration energy is transmitted to the damping spring 3 through the support plate 4. When subjected to vibration, the damping spring 3 will expand and contract, converting the vibration energy into the elastic potential energy of the spring, thereby further buffering and absorbing the vibration.

[0030] The lower half of the pipe 1 has a first arc-shaped sealing gasket 6 inside, which overlaps with the hinged end of the lower half of the pipe 1 and the upper half of the pipe 2. The upper half of the pipe 2 has a second arc-shaped sealing gasket 7 inside, which overlaps with the free end of the lower half of the pipe 1 and the upper half of the pipe 2. The first arc-shaped sealing gasket 6 and the second arc-shaped sealing gasket 7 are combined to form a cylindrical structure. The first arc-shaped sealing gasket 6 and the second arc-shaped sealing gasket 7 are made of silicone rubber. The inner walls of both the lower half of the pipe 1 and the upper half of the pipe 2 are provided with an insulating layer 8, which is made of epoxy resin. Sealing strips 9 are provided on the mating surfaces of the upper pipe 2. Support sleeves 10 are fixedly installed at both ends of the inner side of the first arc-shaped sealing gasket 6. The side of the shock-absorbing spring 3 away from the support plate 4 is connected to the support sleeve 10. A support rod 11 is fixedly connected to the middle of the side of the support plate 4 near the shock-absorbing spring 3. The support rod 11 is slidably sleeved with the support sleeve 10. An upper ear plate 12 is provided on the outer side of the free end of the upper pipe 2. A lower ear plate 13 is provided on the outer side of the free end of the lower pipe 1. A connecting bolt 14 is provided on the upper surface of the upper ear plate 12. The connecting bolt 14 is movably connected to the lower ear plate 13.

[0031] During the installation of the power supply system's piping structure, the lower half of the pipe 1 is first placed in the predetermined position, and the cable is placed on the shock-absorbing rubber pad 5 inside the lower half of the pipe 1. Then, the upper half of the pipe 2 is rotated around the axis using a hinge to close it with the lower half of the pipe 1. At this time, the first arc-shaped sealing gasket 6 and the second arc-shaped sealing gasket 7 cooperate with each other to form a complete cylindrical sealing structure, encasing the cable. Next, the upper ear plate 12 and the lower ear plate 13 are aligned, and the connecting bolt 14 is passed through the upper ear plate 12 and connected to the lower ear plate 13. The bolt is tightened to make the upper half of the pipe 2 and the lower half of the pipe 1 tightly connected. During disassembly, simply unscrew the connecting bolt 14, open the upper half of the pipe 2, and maintenance or replacement of the cable inside the pipe can be performed. The first arc-shaped sealing gasket 6 and the second arc-shaped sealing gasket 7 are made of silicone rubber, which has good elasticity and sealing performance. During installation, after the upper half of the pipe 2 and the lower half of the pipe 1 are closed, the first arc-shaped sealing gasket 6 and the second arc-shaped sealing gasket 7 adhere to each other, forming a tight seal. The pipe forms a closed cylindrical space, preventing external moisture, dust, corrosive gases, etc. from entering the pipe and protecting the cable from the influence of the external environment. The sealing strip 9 set on the mating surface of the lower pipe 1 and the upper pipe 2 further enhances the sealing effect, prevents leakage at the sealing gap, and ensures the stability of the internal environment of the pipe. The support rod 11 on the support plate 4 is slidably sleeved with the support sleeve 10. This structure not only provides support and guidance for the shock-absorbing spring 3, but also limits the excessive deformation of the shock-absorbing spring 3, ensuring the stability and reliability of the shock absorption system. The inner walls of both the lower pipe 1 and the upper pipe 2 are provided with an insulation layer 8. The insulation layer 8 is made of epoxy resin material. Epoxy resin has excellent insulation properties, which can effectively prevent current leakage and prevent electrical connection between the cable and the pipe, ensuring the safety of personnel and equipment. At the same time, the insulation layer 8 can also play a certain protective role, preventing the cable sheath from being scratched, worn, or damaged, and improving the safety of power supply engineering operations.

[0032] Working Principle: During the installation of the power supply system's piping structure, the lower half of the pipe 1 is first placed in the predetermined position. The cable is then placed on the shock-absorbing rubber pad 5 inside the lower half of the pipe 1. Next, the upper half of the pipe 2 is rotated around its axis using hinges to close it with the lower half of the pipe 1. At this point, the first arc-shaped sealing gasket 6 and the second arc-shaped sealing gasket 7 cooperate to form a complete cylindrical sealing structure, encasing the cable. Then, the upper ear plate 12 and the lower ear plate 13 are aligned, and connecting bolts 14 are passed through the upper ear plate 12 and connected to the lower ear plate 13. The bolts are tightened to ensure a tight connection between the upper half of the pipe 2 and the lower half of the pipe 1. Disassembly is then performed. During disassembly, simply unscrew the connecting bolt 14 and open the upper pipe 2 to perform maintenance and replacement operations on the cables inside the pipe. The No. 1 arc-shaped sealing gasket 6 and the No. 2 arc-shaped sealing gasket 7 are made of silicone rubber, which has excellent elasticity and sealing performance. During installation, after the upper pipe 2 and lower pipe 1 are closed, the No. 1 arc-shaped sealing gasket 6 and the No. 2 arc-shaped sealing gasket 7 fit together to form a closed cylindrical space, preventing external moisture, dust, corrosive gases, etc., from entering the pipe interior and protecting the cables from external environmental influences. A sealing gasket is installed on the mating surface between the lower pipe 1 and the upper pipe 2. Seal 9 further enhances the sealing effect, preventing leakage at the sealing gap and ensuring the stability of the pipeline's internal environment. When the cable experiences electromagnetic vibration due to current changes, the vibration is first transmitted to the damping rubber pad 5. The damping rubber pad 5 has certain elasticity and damping characteristics, which can absorb and buffer some of the vibration energy, reducing the transmission of vibration. The remaining vibration energy is transmitted to the damping spring 3 through the support plate 4. The damping spring 3 will expand and contract when subjected to vibration, converting the vibration energy into the elastic potential energy of the spring, thereby further buffering and absorbing the vibration. The support rod 11 on the support plate 4 and the support The sleeve 10 is slidably sleeved. This structure not only provides support and guidance for the shock-absorbing spring 3, but also limits the excessive deformation of the shock-absorbing spring 3, ensuring the stability and reliability of the shock absorption system. The inner walls of both the lower pipe 1 and the upper pipe 2 are provided with an insulation layer 8. The insulation layer 8 is made of epoxy resin material. Epoxy resin has excellent insulation properties, which can effectively prevent current leakage, prevent electrical connection between the cable and the pipe, and ensure the safety of personnel and equipment. At the same time, the insulation layer 8 can also play a certain protective role, preventing the cable sheath from being scratched, worn or damaged, and improving the safety of power supply engineering operations.
