Abstract
Description

[0002] The plastic double-wall wound corrugated pipe is composed of an inner and an outer pipe wall. The inner pipe wall is smooth, and the outer wall is corrugated. This double-wall structure not only ensures the rigidity and load-bearing capacity of the pipe, but also has a certain flexibility and flexural resistance.
[0003] The existing plastic double-wall wound corrugated pipes mostly use socket connections. The pipes are manually pushed or clamped by a clamping device and then pushed into the interior of another pipe, and then fixed by special connectors (such as rubber gaskets, pipe sleeves, etc.). This connection method is simple and easy to implement, and is suitable for pipes with a larger diameter and applications with medium and low pressures.
[0004] In the above technology, although the pipes can be connected manually, etc., it is necessary to first determine the position of the pipe connection at the pipe mouth, and then slide one end of the pipe into the interior of the other pipe by pushing. This method increases the complexity of pipe positioning and may cause soil and the like to enter the pipe during pushing, resulting in pollution. Therefore, a plastic double-wall wound corrugated pipe is proposed to solve the above problems. Summary of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0032] Referring to Figure 1 、 Figure 2 and Figure 4 , an embodiment provided by the present utility model: a plastic double-wall corrugated pipe, including a pipe body 1. The pipe body 1 is the main part of the double-wall corrugated pipe and can be used for drainage work. The outer part of the left end of the pipe body 1 slides inside the connecting port 6. By sliding the left part of the pipe body 1 into the connecting port 6 at the right end of another group of pipes, multiple groups of pipes can be connected and fixed conveniently through bolts and other devices. The right end of the pipe body 1 is fixedly connected with a connecting port 6. The inner diameter of the connecting port 6 is the same as the outer corrugation diameter of the pipe body 1, so that the pipe body 1 can slide in for positioning. Fixed blocks 5 are fixedly connected to both the upper and lower parts of the connecting port 6. The fixed blocks 5 can clamp the clamping blocks 10 to determine the position of the connecting plate 2 relative to the connecting port 6, facilitating heating connection. A sliding ring 4 is slidably connected to the outside of the connecting port 6. The sliding ring 4 can keep the position of the connecting plate 2 relatively fixed and can protect the connecting port 6, increasing its pressure-bearing effect. Connecting plates 2 are fixedly connected to both the upper and lower parts of the sliding ring 4. The connecting plates 2 can support the left part of the pipe body 1 to make its position relative to the connecting port 6 fixed, facilitating the pipe body 1 to slide into the inside of the connecting port 6. The outer part of the left end of the connecting plate 2 slides outside the connecting port 6. The connecting port 6 supports to make the sliding ring 4 and the connecting plate 2 relatively fixed. The right end of the connecting plate 2 is fixedly connected with a positioning port 3. The positioning port 3 is conical, so that the left end of the pipe body 1 can automatically align and slide into the middle of the upper and lower connecting plates 2.
[0033] Referring to Figure 2 、 Figure 3 and Figure 5, a square groove 9 is formed in the left end side of the connecting plate 2. The square groove 9 can restrict the block 10 to slide only horizontally. A block 10 is slidably connected inside the square groove 9. The left end of the block 10 is beveled and can slide into the inside of the connecting plate 2 when being extruded, facilitating the sliding of the connecting plate 2 and the sliding ring 4 to the outside of the connection port 6. The right side end of the block 10 is in contact with the left part of the fixed block 5. The fixed block 5 fixes the position of the connecting plate 2 relative to the connection port 6. In this way, it is convenient to fix the connecting plate 2 to the connection port 6 by heating or other means. Both the upper and lower parts of the block 10 are fixedly connected with sliders 11. The outside of the sliders 11 is slidably connected inside the square groove 9. The sliders 11 are restricted by the square groove 9 to slide within a fixed distance, so that the block 10 cannot completely slide out of the inside of the square groove 9. An inner shell 12 is fixedly connected inside the pipe body 1. The inner shell 12 is the inner wall of a double-wall wound corrugated pipe. A protective component is fixed inside the connection port 6.
[0034] Referring to Figure 1 - Figure 2 , the protective component includes an epoxy resin coating 7. The epoxy resin coating 7 can protect the internal polyethylene coating 8 and the pipe body 1 from being corroded by the outside world, increasing the safety at the connection port 6. The outside of the epoxy resin coating 7 is fixedly connected inside the connection port 6, and the connection port 6 keeps the epoxy resin coating 7 relatively fixed and formed. An inner polyethylene coating 8 is fixedly connected inside the epoxy resin coating 7. The polyethylene coating 8 can be in contact with the pipe body 1, so that the pipe body 1 will not wear out the epoxy resin coating 7, increasing the wear resistance inside the connection port 6. The polyethylene coating 8 can make the inside of the polyethylene coating 8 be in contact with the outside of the left end of the pipe body 1.
[0035] Working principle: When installing, the sliding ring 4 can be slid to the outside of the connection port 6. The connection port 6 supports and keeps the sliding ring 4 fixed, and the connecting plate 2 slides with the sliding ring 4. The block 10 slides into the inside of the square groove 9 under the extrusion of the fixed block 5. Then, when sliding until the connecting plate 2 is blocked by the connection port 6 and cannot slide anymore, it can be slid so that the block 10 slides out until it is restricted by the slider 11 and stops sliding, keeping the sliding ring 4 relatively fixed. Then, heating can be carried out through a heating device or the like for fixing. Subsequently, the left end of the pipe body 1 is slid into the right part of the positioning port 3 and slides inside the connection port 6 through an extrusion or clamping device. The left end of the pipe body 1 is extruded to the central position by the positioning port 3. At this time, the lower end of the left part of the pipe body 1 does not contact the ground. Subsequently, the pipe body 1 continues to slide and is clamped by the connecting plate 2 and slides straight into the inside of the connection port 6. The pipe body 1 is in contact with the polyethylene coating 8 to protect the epoxy resin coating 7. Then, the pipe body 1 and another set of connection ports 6 can be fixedly connected through fixing devices such as bolts. In this way, multiple sets of double-wall wound corrugated pipes can be fixedly connected in sequence. And when in use, the sliding ring 4 can keep the connection port 6 formed when it is subjected to a large pressure and will not be flattened together with the internal pipe body 1. And when the connection port 6 is corroded by the outside world, it can be protected by the internal epoxy resin coating 7 and will not corrode the internal polyethylene coating 8 and the pipe body 1, increasing the sealing performance of the pipeline.
[0036] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
