Description

Technical Field

[0001] This utility model belongs to the field of power pipe technology, specifically relating to a plastic power pipe resistant to silt deposition. Background Technology

[0002] Plastic power conduits are pipes made of high-density polyethylene or polyvinyl chloride, specifically designed to protect power cables. They feature high strength, corrosion resistance, and excellent insulation properties, resisting complex environments such as acids, alkalis, and humidity, effectively preventing cable wear and electromagnetic interference. Compared to traditional metal pipes, they are lighter, more flexible, easier to install, and less expensive, making them widely used in urban power grid upgrades, building construction, and underground cable laying, and are an important component of modern power infrastructure.

[0003] A known authorized patent with application number 202222317898.8 discloses a PVC-modified plastic power conduit with anti-collapse properties, comprising a PVC-modified pipe body with an anti-interference layer on its inner wall. In this invention, because the spiral steel wire is wound around the outer wall of the pipe connection layer along with the corrugated strip, and the corrugated strip is made of polytetrafluoroethylene (PTFE), it possesses good electrical insulation, good anti-aging resistance, and mechanical toughness. The combined effect of the rubber strip and the spiral steel wire effectively enhances the corrugated strip's compressive strength and deformation resistance, thereby improving the power conduit's anti-collapse effect. This prevents the outer layer of the power conduit from easily aging during long-term contact with the ground, effectively extending the pipe's service life. Simultaneously, the application of PVC coating effectively improves the corrosion resistance of the outer surface of the power conduit, preventing surface corrosion caused by long-term underground exposure and ensuring the stability of the internal structure of the pipe.

[0004] However, during the implementation of the relevant technology, the following problems were found with the above technical solution: the device is only designed to resist collapse, but in actual use, silt and sand deposition occurs, which makes it impossible to pull out the wire harness inside the pipe, resulting in the need to dig it up for maintenance, which greatly increases the maintenance cost.

[0005] Therefore, a plastic power pipe resistant to sediment deposition is proposed to solve the above problems. Utility Model Content

[0006] This invention proposes a plastic power pipe resistant to silt deposition, which solves the problem that in related technologies, the device is only designed to resist collapse, but in actual use, silt deposition occurs, making it impossible to pull out the wires inside the pipe, which requires digging for maintenance and greatly increases maintenance costs.

[0007] The technical solution of this utility model is as follows: A plastic power pipe resistant to sediment deposition, comprising: pipe bend; Straight pipes are installed at both ends of the bend and connecting components are used to connect the bend and the straight pipes; The inner wall of the bend is provided with a first water guide strip; The bend is designed with a bending angle of 5±2°. A discharge assembly is provided at the bend on the outer wall of the bend. Both ends of the bend and the straight pipe are provided with retaining edges.

[0008] Preferably, the discharge assembly includes a drain pipe disposed below the bend of the bend and a baffle disposed inside the drain pipe. The baffle is inclined and has an upwardly bent arc at its top. The baffles are staggered.

[0009] Preferably, the connecting component includes a first connecting block and a second connecting block. The outer wall of the first connecting block is provided with a threaded head, and the interior of the second connecting block is provided with a threaded groove. The threaded head and the threaded groove are threadedly connected, and a sealing ring is provided between the first connecting block and the second connecting block.

[0010] Preferably, the bottom of both the first connecting block and the second connecting block is provided with a pressing groove corresponding to the retaining edge, and a gasket is provided on the outer wall of the pressing groove, the gasket being located between the pressing groove and the retaining edge.

[0011] Preferably, the inner walls at both ends of the bend are provided with a second water guide strip, which is slightly smaller than the first water guide strip.

[0012] Preferably, one end of the straight pipe is provided with a plug, the outer wall of the plug is provided with a retainer, the inner side wall of the retainer is fitted onto the outer wall of the retainer, the plug is inserted into the inner wall of the straight pipe, and both the plug and the retainer are made of rubber.

[0013] Preferably, the straight pipe and the bent pipe are made of modified polypropylene and have a lubricant added to their inner sides.

[0014] The working principle and beneficial effects of this utility model are as follows: By designing the connecting components and incorporating internal sealing rings and gaskets, the pipe's sealing performance is enhanced. This double-sealing design significantly reduces the probability of silt and water intrusion. The water guide strips, without affecting cable installation, form a flow channel with the inner wall. When a small amount of water intrudes into the pipe, it no longer flows freely; instead, due to surface tension, the water preferentially accumulates within the channel formed by the guide strips, creating an organized drainage path. Relying on gravity for directional flow, this effectively carries away intruding micro-silt particles, preventing them from uniformly spreading and depositing. Attached Figure Description

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0019] Implementation Please see Figure 1 -4. A plastic power pipe resistant to sediment deposition, comprising: Bend 2; Straight pipes 1 are installed at both ends of the bend 2, and connecting components are used to connect the bend 2 and the straight pipes 1; The inner wall of the bend 2 is provided with a first water guide strip 6; The bend 2 is designed with a bending angle of 5±2°. A discharge assembly is provided at the bend of the outer wall of the bend 2. Both ends of the bend 2 and the straight pipe 1 are provided with retaining edges 5; The discharge assembly includes a drain pipe 4 located below the bend of the bend in the bend 2 and a baffle 9 located inside the drain pipe 4. The baffle 9 is inclined and has an upward-bent arc shape at the top. The baffles 9 are staggered. The connecting assembly includes a first connecting block 10 and a second connecting block 11. The outer wall of the first connecting block 10 is provided with a threaded head 12, and the interior of the second connecting block 11 is provided with a threaded groove 13. The threaded head 12 and the threaded groove 13 are threadedly connected. A sealing ring 14 is provided between the first connecting block 10 and the second connecting block 11. The bottom of the first connecting block 10 and the second connecting block 11 are provided with pressing grooves 16 corresponding to the retaining edge 5. A gasket 15 is provided on the outer wall of the pressing groove 16, and the gasket 15 is located between the pressing groove 16 and the retaining edge 5. A plug 3 is provided at one end of the straight pipe 1. A sleeve 7 is provided on the outer wall of the plug 3. The inner side wall of the sleeve 7 is fitted onto the outer wall of the clamping edge 5. The plug 3 is inserted into the inner wall of the straight pipe 1. Both the plug 3 and the sleeve 7 are made of rubber.

[0020] The technical solution provided in this embodiment is as follows: During use, the position of the bend 2 is confirmed. A drainage well or other water collection point needs to be opened at the bottom of the bend 2. Then, straight pipes 1 are connected to both ends of the bend 2. During connection, the sealing ring 14 is first placed on the outer wall of the first connecting block 10. Then, a gasket 15 is fitted onto the outer wall of the retaining edge 5. Next, the first connecting block 10 and the second connecting block 11 are connected. During connection, the first connecting block 10 is rotated, and the threaded head 12 and the threaded groove 13 are threaded together. During connection, the first connecting block 10 and the second connecting block 11 together clamp the sealing ring 14, sealing the connection. The bottom clamping groove 16 clamps the gasket 15. The connection is sealed. During use, the sealing ring 14 isolates vertical mud and sand, and the gasket 15 isolates axial mud and sand, thus ensuring a thorough seal at the connection. After the wiring is completed, the power conduit is placed. During the construction process, the plug 3 and the clamp 7 must be kept in place to prevent mud and sand and other debris from entering the pipe. After construction, the plug 3 is removed, and then the wiring is performed. After the wiring is completed, it can be used. During use, if mud and sand are deposited, the first water guide strip 6 and the second water guide strip 8 form a small flow channel with the inner wall without affecting the cable laying. When a small amount of water enters the pipe, it will no longer be in a state of overflow. Water will preferentially gather in the channel formed by the guide ribs due to surface tension, forming an organized drainage path. Relying on gravity for directional flow, it can effectively carry away the intruding small mud and sand particles, preventing them from being evenly spread and deposited. The water inside will enter the interior of the bend 2, and then through the interior of the drain pipe 4 before being discharged. In the event of a blockage in the pipe, water is quickly drawn in by high-pressure gas to expel the blockage. During discharge, the baffle 9, due to its own structure, can reduce the discharge volume in a high-pressure environment without affecting the discharge of a small amount of water, thus avoiding excessive pressure drop during the unblocking process.

[0021] Furthermore, the inner walls at both ends of the bend 2 are provided with second water guide strips 8, which are slightly smaller than the first water guide strip 6.

[0022] Specifically, the smaller second water guide strip 8 can prevent mud and sand from entering through the gap connecting with the first water guide strip 6, and can quickly drain the water guided by the first water guide strip 6 without being affected by the second water guide strip 8.

[0023] Furthermore, the straight pipe 1 and the bent pipe 2 are made of modified polypropylene, and a lubricant is added to the inside.

[0024] Specifically, it has high strength and good heat resistance. Its material itself is smooth and wear-resistant, making it easier to drain mud and sand and thread the wire. The added lubricant further improves its flatness and drainage capacity.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
