Description

Technical Field

[0001] The utility model relates to the technical field of double-wall winding pipes, in particular to a double-wall winding pipe with high structural strength. Background Technique

[0002] The double-wall winding pipe is made by helically winding and welding a special-shaped strip of steel-plastic composite, and its inner wall is smooth and flat. This kind of pipe has the advantages of corrosion resistance, light weight, simple installation, large flow capacity, long service life, etc., and can replace pipes made of high-energy-consuming materials (such as cement, cast iron, ceramics, etc.), and belongs to an environment-friendly green product.

[0003] When using the winding pipe, the winding pipe is buried in the ground layer, and the municipal rainwater is drained through the winding pipe. During the drainage process of the winding pipe, because the winding pipe is buried relatively shallow, the winding pipe will be subjected to an external inward pressure. If the ring stiffness of the winding pipe is not enough, it will cause the winding pipe to deform during construction or use because it cannot withstand the external pressure. Moreover, the winding pipe drains water for a long time, and residues such as bacteria and insects in the rainwater will adhere to the winding pipe and are inconvenient to clean, resulting in the winding pipe being easily corroded and damaged, affecting the use effect of the winding pipe.

[0004] Therefore, we propose a double-wall winding pipe with high structural strength to solve the problems mentioned above. Content of the Utility Model

[0005] 1. Technical problems to be solved by the utility model:

[0006] The purpose of the utility model is to provide a double-wall winding pipe with high structural strength to solve the problems in the current market mentioned in the above background technique.

[0007] 2. Technical solution:

[0008] To achieve the above purpose, the utility model provides the following technical solution: A double-wall winding pipe with high structural strength, including a pipe body, a plurality of first strengthening members and a plurality of second strengthening members are installed on the outer side of the pipe body, and a first connecting pipe and a second connecting pipe are respectively installed at the upper and lower ends of the pipe body;

[0009] The inner wall of the first connecting pipe is fixedly provided with limiting strips at equal intervals, and a first limiting groove is opened at the position corresponding to the limiting strips on the outer wall of the second connecting pipe. Moreover, a filtering member is installed on the inner wall of the first connecting pipe, and the lower side wall of the filtering member is attached to the upper end of the pipe body. The pipe body filters the medium through the filtering member.

[0010] Furthermore, the first strengthening members are distributed at equal angles about the center of the pipe body, and a plurality of second strengthening members are distributed at equal intervals up and down on the outer wall of the pipe body.

[0011] Through the above technical solution, with the cooperation of the first reinforcing member and the second reinforcing member, the strength and stability of the pipe body can be enhanced.

[0012] Furthermore, the second reinforcing member includes a buffer pad fixed to the outer wall of the pipe body. A groove is formed in the middle of the side of the buffer pad away from the pipe body, and a buffer ring is fixed inside the groove.

[0013] Through the above technical solution, the buffer ring and the buffer pad can cooperate to buffer the external impact force.

[0014] Furthermore, the filter member includes a mounting plate that fits against the upper end of the pipe body and the inner wall of the first connecting pipe. A filter net is fixed inside the mounting plate, and an auxiliary block is fixed to the end face of the filter net. Moreover, limiting grooves II are equiangularly formed on the outer wall of the mounting plate, and the limiting grooves II are arranged in one-to-one correspondence with the limiting strips.

[0015] Through the above technical solution, impurities can be filtered by the filter net.

[0016] Furthermore, the limiting grooves II and the rubber bumps are staggered, and the rubber bumps are fixedly installed on the end face of the mounting plate, and the rubber bumps fit against the lower end face of the limiting strips.

[0017] Through the above technical solution, after the rubber bumps rotate and extend into the lower ends of the limiting strips, the fixation of the filter member can be realized.

[0018] Furthermore, the sum of the height of the limiting strip and the thickness of the mounting plate is equal to the height of the first connecting pipe.

[0019] Through the above technical solution, after the mounting plate is displaced into the first connecting pipe, it can rotate inside the first connecting pipe.

[0020] 3. Beneficial effects:

[0021] Adopting the technical solution provided by the present utility model, compared with the prior art, the double-wall winding pipe with high structural strength of the present utility model enhances its own strength and stability through the first reinforcing member and the second reinforcing member, extends the service life and improves the use safety. At the same time, it is convenient to disassemble and assemble the filter member to filter impurities, and it is not easy to be corroded. The specific content is as follows:

[0022] During the use of the pipe body, through the first reinforcing members distributed at equal angles, the self-supporting effect can be strengthened to resist the impact force existing outside or inside the pipe body. At the same time, the second reinforcing members arranged at equal intervals further improve the strength of the pipe body. When an external impact occurs, it first squeezes towards the buffer ring, and the buffer ring absorbs the impact force in advance. At the same time, with the auxiliary effect of the buffer pad, the overall anti-deformation ability is further improved, the service life of the pipe body is extended, and the use safety is improved;

[0023] Align the second limiting groove opened on the side of the mounting plate with the limiting strip, then insert the filter element into the interior of the first connecting pipe until the filter element fits against the end of the pipe body. Then, rotate the filter element inside the first connecting pipe through the auxiliary block until the rubber bump installed on the mounting plate rotates into the lower end interior of the limiting strip. Reverse-rotate the filter element through the auxiliary block to disassemble the filter element, thereby realizing the quick disassembly and assembly operation of the filter element. Furthermore, impurities and garbage can be filtered through the filter net, and the pipe body is not easily corroded, further extending the service life. Description of the Drawings

[0033] Please refer to Figures 1-4 , a double-wall wound pipe with high structural strength, including a pipe body 1. A number of first reinforcing members 2 and a number of second reinforcing members 3 are installed on the outer side of the pipe body 1, and a connecting pipe one 4 and a connecting pipe two 5 are respectively installed at the upper and lower ends of the pipe body 1; the first reinforcing members 2 are equally angularly distributed about the center of the pipe body 1, and a number of the second reinforcing members 3 are equally spaced up and down on the outer wall of the pipe body 1; the second reinforcing member 3 includes a buffer pad 31 fixed on the outer wall of the pipe body 1. A groove 32 is formed in the middle of the side of the buffer pad 31 away from the pipe body 1, and a buffer ring 33 is fixed inside the groove 32;

[0034] During the use of the pipe body 1, through the first reinforcing members 2 that are equally angularly distributed, the self-supporting effect can be enhanced to resist the impact force existing outside or inside the pipe body 1. At the same time, the second reinforcing members 3 that are equally spaced further improve the strength of the pipe body 1. When an external impact occurs, it first squeezes towards the buffer ring 33. The buffer ring 33 absorbs the impact force in advance. At the same time, with the assistance of the buffer pad 31, the overall anti-deformation ability is further improved, the service life of the pipe body 1 is prolonged, and the use safety is improved;

[0035] The inner wall of the first connecting pipe 4 is fixedly provided with limiting strips 41 at equal intervals, and the outer wall of the second connecting pipe 5 is provided with a first limiting groove 51 at the position corresponding to the limiting strip 41. Moreover, a filtering element 6 is installed on the inner wall of the first connecting pipe 4, and the lower side wall of the filtering element 6 is attached to the upper end of the pipe body 1. The pipe body 1 filters the medium through the filtering element 6. The filtering element 6 includes a mounting plate 61 attached to the upper end of the pipe body 1 and the inner wall of the first connecting pipe 4. A filter net 62 is fixedly arranged inside the mounting plate 61, and an auxiliary block 63 is fixed to the end face of the filter net 62. Moreover, second limiting grooves 64 are arranged on the outer wall of the mounting plate 61 at equal angles, and the second limiting grooves 64 are arranged in one-to-one correspondence with the limiting strips 41. The second limiting grooves 64 and the rubber bumps 65 are distributed alternately, and the rubber bumps 65 are fixedly installed on the end face of the mounting plate 61, and the rubber bumps 65 are attached to the lower end face of the limiting strip 41. The sum of the height of the limiting strip 41 and the thickness of the mounting plate 61 is equal to the height of the first connecting pipe 4.

[0036] When the filtering element 6 needs to be installed, first, the second limiting grooves 64 arranged on the side of the mounting plate 61 are aligned with the limiting strips 41, and then the filtering element 6 is inserted into the first connecting pipe 4 until the filtering element 6 is attached to the end of the pipe body 1. Then, the filtering element 6 is rotated inside the first connecting pipe 4 through the auxiliary block 63, so that the rubber bumps 65 installed on the mounting plate 61 rotate into the lower part inside the limiting strip 41 to achieve installation. By rotating the filtering element 6 in the reverse direction through the auxiliary block 63, the filtering element 6 can be disassembled, thus realizing the quick disassembly and assembly operation of the filtering element 6. Furthermore, impurities and garbage can be filtered through the filter net 62, and the pipe body 1 is not easily corroded, further extending the service life.

[0037] Working principle: When using the double-wall winding pipe with high structural strength, as Figures 1-4 shown, through the first strengthening members 2 distributed at equal angles, the self-supporting effect is strengthened to resist the impact force existing outside or inside the pipe body 1. At the same time, the second strengthening members 3 arranged at equal intervals utilize the functions of the buffer rings 33 and the buffer pads 31 to improve the overall anti-deformation ability, extend the service life of the pipe body 1 and improve the use safety. When the filtering element 6 needs to be installed, first, the second limiting grooves 64 arranged on the side of the mounting plate 61 are aligned with the limiting strips 41, and then the filtering element 6 is inserted into the first connecting pipe 4, and then the filtering element 6 is rotated until the rubber bumps 65 installed on the mounting plate 61 rotate into the lower part inside the limiting strip 41, realizing the quick disassembly and assembly operation of the filtering element 6. Furthermore, impurities and garbage can be filtered through the filter net 62, and the pipe body 1 is not easily corroded, further extending the service life.
