Description

Technical Field

[0001] This utility model relates to the technical field of power pipelines, specifically to an anti-aging power pipeline. Background Technology

[0002] my country's plastic pipe industry has developed rapidly, and its quality is constantly improving. Among them, polyethylene power pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas transmission pipes, electrical and telecommunications protection sleeves, industrial pipes, and agricultural pipes due to their unique advantages.

[0003] For example, the high-pressure-resistant and aging-resistant polyethylene power pipe with authorization announcement number "CN219918379U" solves the problem that existing high-pressure-resistant and aging-resistant polyethylene power pipes have weak heat insulation and corrosion resistance, thus reducing their effectiveness. The above-mentioned buffer assembly allows the second protective layer, buffer rubber block, buffer rod, and buffer spring to work together so that the buffer spring inside the first protective layer can contract, and then the buffer rod contracts inside the buffer opening on the buffer rubber block, thereby reducing the compressive force of the power pipe body's expansion and deformation. Considering that the buffer assembly in existing high-pressure-resistant and aging-resistant polyethylene power pipes, where the second protective layer, buffer rubber block, buffer rod, and buffer spring are directly wrapped around the outer wall of the pipe, is easy to disassemble but difficult to replace. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing high-pressure-resistant and aging-resistant polyethylene power pipes are directly wrapped around the outer wall of the pipe, making them easy to disassemble and replace but difficult to replace. Therefore, this invention proposes an anti-aging power pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-aging power conduit, comprising an outer layer and a connecting ring, wherein the end of the outer layer is fixedly connected to the connecting ring, the outer wall of the connecting ring is threadedly connected to a fixing screw, the inner wall of the fixing screw is threadedly connected to a connecting strip, the outer wall of the connecting strip is fitted to the connecting ring, and the outer wall of the connecting strip is connected to an anti-pressure mechanism.

[0006] This setting allows the fixing screw to pass through the connecting strip and connect to the connecting ring via a thread, thus making the connecting ring more firmly fixed to the outer wall of the connecting ring.

[0007] Preferably, the anti-compression mechanism includes a mounting ring, the inner wall of which is inserted into a connecting strip, the inner wall of the other side of the mounting ring abutting against a rubber block, and the upper end of the rubber block being fixedly connected to an arc-shaped plate.

[0008] The pressure-resistant mechanism described in this design employs a multi-layered composite structure, which effectively disperses external pressure and prevents pipe deformation. The combination of rubber blocks and arc-shaped plates provides excellent buffering performance, absorbing energy when subjected to external impacts and protecting the internal structure of the pipe from damage.

[0009] Preferably, the inner wall of the mounting ring is movably connected to the screw, the outer wall of the screw is threadedly connected to the nut, and the inner wall of the outer layer is connected to a reinforcing mechanism.

[0010] This feature uses precision threads to secure the screws and the connecting ring, ensuring a firm and reliable connection while facilitating installation and disassembly.

[0011] Preferably, the reinforcing mechanism includes a central layer, the outer wall of the central layer is fixedly connected to the outer layer, the inner wall of the central layer is fixedly connected to the inner layer, and the inner wall of the inner layer is fixedly connected to the smooth layer.

[0012] This enhanced structure, consisting of a central layer, an inner layer, and a smooth layer, significantly improves the overall strength and durability of the pipeline. The smooth inner wall design reduces frictional resistance when cables are threaded through, facilitating construction and installation.

[0013] Preferably, the outer wall of the screw abuts against the mounting ring.

[0014] This setting ensures that the screw and nut are tightened to guarantee a secure connection between the mounting ring and the connecting strip, preventing loosening due to vibration.

[0015] The present invention proposes an anti-aging power conduit, the advantages of which are as follows: by bending and twisting the installation ring to form a notch and fitting it into the outer layer of the power conduit, and by sliding the two ends of the arc plate into the circular groove of the installation ring one by one, the control screw and nut can be separated and installed from the installation ring, the arc plate can be freely replaced, no special tools are required during the installation process, and assembly can be completed with simple operation, making disassembly and assembly even simpler.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Please see Figure 1-6 In this embodiment, an anti-aging power conduit includes an outer layer 1 and a connecting ring 2. The end of the outer layer 1 is fixedly connected to the connecting ring 2. The outer layer 1 is modified PE containing a high concentration of antioxidants and ultraviolet absorbers (such as benzotriazoles). The outer wall of the connecting ring 2 is threadedly connected to a fixing screw 3. The inner wall of the fixing screw 3 is threadedly connected to a connecting strip 4. The outer wall of the connecting strip 4 is in contact with the connecting ring 2. The outer wall of the connecting strip 4 is connected to a pressure-resistant mechanism 5.

[0025] The pressure-resistant mechanism 5 includes a mounting ring 501, which transmits pressure to the rubber block 501 through the arc plate 503. The rubber material absorbs the impact energy through elastic deformation. The inner wall of the mounting ring 501 is inserted into the connecting strip 4, and the inner wall on the other side of the mounting ring 501 is pressed against the rubber block 502. The upper end of the rubber block 502 is fixedly connected to the arc plate 503.

[0026] The mounting ring 501 is bent to form a notch and inserted into the outer layer 1 of the power conduit. The two ends of the arc plate 503 are slid into the circular groove of the mounting ring 501 one by one. The control screw 6 and nut 7 are separated and installed from the mounting ring 501, allowing the arc plate 503 to be freely replaced. No special tools are required during the installation process. Assembly can be completed with simple operation, making disassembly and assembly even simpler.

[0027] The inner wall of the mounting ring 501 is movably connected to the screw 6, the outer wall of the screw 6 is threadedly connected to the nut 7, and the inner wall of the outer layer 1 is connected to a reinforcing mechanism 8. The reinforcing mechanism 8 includes a central layer 801, which is made of glass fiber or carbon fiber reinforced composite material to improve compressive and impact resistance. The outer wall of the central layer 801 is fixedly connected to the outer layer 1, and the inner wall of the central layer 801 is fixedly connected to the inner layer 802. The inner layer 802 is insulated with nano-ceramic particles to enhance arc resistance and partial discharge capability. The inner wall of the inner layer 802 is fixedly connected to the smooth layer 803, and the outer wall of the screw 6 is pressed against the mounting ring 501.

[0028] Working principle:

[0029] The external bolts are used to seal the connection between the connecting ring 2 and other power pipes in the same location, thus extending the overall length of the power pipe. At the same time, the construction workers put the connecting strip 4 on the outer layer 1 of the power pipe and use the fixing screw 3 to thread it through the connecting strip 4 and connect it to the connecting ring 2. Similarly, the installation ring 501 is bent to form a notch and put into the outer layer 1 of the power pipe. Then, the two ends of the arc plate 503 are slid into the circular groove of the installation ring 501 one by one. Finally, the installation ring 501 on the inner wall of the other side is inserted into the connecting strip 4 to restrict the position of the installation ring 501 on the connecting ring 2. The screw 6 is used to thread it through the installation ring 501 and the nut 7 to achieve the final tightening of the installation ring 501. The whole process can be completed with only conventional tools.

[0030] When the arc-shaped plate 503 of the pressure-resistant mechanism 5 is subjected to pressure, it transmits the pressure to the rubber block 501. The impact energy is absorbed through the elastic deformation of the rubber material, while the tight fit between the mounting ring 501 and the connecting strip 4 ensures uniform pressure distribution. The multi-layer composite structure design of the reinforcing mechanism 8 effectively improves the overall pressure resistance of the pipeline. The fiber-reinforced material of the central layer 801 can resist external impacts, while the insulating material with added nano-ceramic particles in the inner layer 802 enhances the resistance to electric arcs and partial discharges. The smooth layer 803 made of polypropylene not only reduces the frictional resistance when cables are threaded through the pipe but also reduces wear on the inner wall of the pipe, extending its service life.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
