Description

Technical Field

[0001] This utility model belongs to the technical field of PVC pipe equipment, and specifically relates to a PVC pipe with an anti-clogging structure. Background Technology

[0002] PVC pipes are made primarily of polyvinyl chloride with the addition of other auxiliary materials. They possess good strength and a long service life, and are widely used in municipal engineering and industrial water supply and drainage.

[0003] However, existing PVC pipes have obvious shortcomings in long-term use: on the one hand, the accumulation of flowing objects in the pipes can easily cause blockages, affecting the flow of liquids and causing backflow; on the other hand, traditional anti-blockage structures, such as single cutter components, can only initially break up the blockages, and long-term accumulation will reduce the anti-blockage effect, and disassembly is complicated and maintenance costs are high. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the prior art, the present invention provides a PVC pipe with an anti-clogging structure to solve the problems in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a PVC pipe with an anti-clogging structure, including a connecting pipe, wherein both ends of the connecting pipe are provided with an integrally formed annular limiting platform, and the two annular limiting platforms are respectively bonded and fixed to the ends of a first PVC pipe and a second PVC pipe; a connecting mechanism is provided at the top of the connecting pipe; the connecting mechanism includes an arc-shaped fixing plate, and a connecting groove is opened on the surface of the connecting pipe, wherein the inner wall of the connecting groove and a protrusion provided at the bottom of the arc-shaped fixing plate are slidably connected.

[0006] Furthermore, a sealing strip is fixedly connected to the outer surface of the arc-shaped fixing plate, and a sealing strip is fixedly connected to the surface of the connecting pipe; when the arc-shaped fixing plate slides to close with the connecting groove, the sealing strip and the sealing strip press against each other to form a seal.

[0007] Furthermore, a connecting block is fixedly connected to the side of the connecting pipe, and a positioning plate is slidably inserted inside the connecting block. The positioning plate and the arc-shaped fixing plate are fixedly connected on one side. A fixing rod is slidably inserted through the side of the connecting block, and the fixing rod is slidably inserted on one side of the positioning plate.

[0008] Furthermore, a spring is fitted onto the surface of the fixing rod, one end of the spring is fixedly connected to the top of the fixing rod, and the end of the spring away from the top of the fixing rod is fixedly connected to one side of the connecting block.

[0009] Furthermore, the inner wall of the connecting pipe located below the arc-shaped fixing plate is provided with an annular groove, and a filter screen is inserted into the annular groove.

[0010] Furthermore, the filter screen can be removed or inserted from the annular groove along the axial direction of the connecting pipe, and the filter screen is made of stainless steel.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. This utility model uses a stainless steel filter screen to directly intercept impurities in the flowing liquid inside the pipeline. It can effectively block solid impurities and some viscous impurities from entering the downstream of the pipeline, reducing the blockage problem caused by impurity accumulation from the source, thereby reducing the risk of obstructed liquid flow and backflow, and ensuring the smoothness of pipeline drainage or water supply.

[0013] 2. In this utility model, the filter screen adopts an axially detachable design. When it is necessary to clean or replace the filter screen, simply pull out the fixing rod and slide open the arc fixing plate to easily remove the filter screen from the annular groove. The operation is simple and does not require large-scale disassembly of the entire pipeline. On the other hand, the stainless steel filter screen has high strength and corrosion resistance, and a long service life, which reduces the frequency of filter screen replacement and reduces maintenance costs and manual labor.

[0014] 3. In this utility model, the sealing strip on the outer surface of the arc-shaped fixing plate cooperates with the sealing strip on the surface of the connecting pipe to form a tight seal when the arc-shaped fixing plate is closed, effectively preventing liquid leakage in the pipeline and avoiding environmental pollution or resource waste caused by leakage; the limiting and fixing structure composed of the connecting block, the locking plate, the fixing rod and the spring prevents the arc-shaped fixing plate from loosening or shifting due to liquid impact and other factors during pipeline operation, ensuring the stability of the entire pipeline structure and extending the service life of the pipeline.

[0024] Example 1:

[0025] like Figure 1-3As shown, this utility model discloses a PVC pipe with an anti-clogging structure, including a connecting pipe 1, with an integrally formed annular limiting platform 101 at both ends of the pipe. One end of the first PVC pipe 102 is aligned with the inner wall of the annular limiting platform 101 at one end of the connecting pipe 1, and the two can be bonded and fixed using a PVC-specific adhesive. Similarly, one end of the second PVC pipe 103 is bonded and fixed to the annular limiting platform 101 at the other end of the connecting pipe 1, forming a complete liquid conveying channel. The annular limiting platform 101 not only plays a positioning role, but also enhances the structural strength of the pipe connection, preventing the connection from falling off or breaking due to liquid pressure.

[0026] The connecting mechanism 2 includes an arc-shaped fixing plate 201, a connecting block 203, a locking plate 204, a fixing rod 205, and a spring. A connecting groove 202 is formed on the surface of the connecting pipe 1. A protrusion at the bottom of the arc-shaped fixing plate 201 can slide along the inner wall of the connecting groove 202, enabling the arc-shaped fixing plate 201 and the connecting pipe 1 to open and close. A rubber sealing strip is bonded to the outer surface of the arc-shaped fixing plate 201, and a rubber sealing strip is bonded to the surface of the connecting pipe 1 corresponding to the edge of the connecting groove 202. When the arc-shaped fixing plate 201 slides to fully close with the connecting groove 202, the sealing strip and the sealing strip press against each other to form a sealing structure, preventing liquid leakage from the connecting groove 202.

[0027] Two symmetrically distributed connecting blocks 203 are welded and fixed to the side of the connecting pipe 1. A rectangular groove is formed inside each connecting block 203. A positioning plate 204 is slidably inserted into the rectangular groove, and one end of the positioning plate 204 is welded and fixed to one side of the arc-shaped fixing plate 201, allowing the positioning plate 204 to slide synchronously along the groove with the arc-shaped fixing plate 201. A circular hole communicating with the rectangular groove is formed on the side of the connecting block 203, through which a fixing rod 205 slides. A positioning hole adapted to the fixing rod 205 is formed on the side of the positioning plate 204. When the arc-shaped fixing plate 201 is closed, the fixing rod 205 can slide into the positioning hole, limiting and fixing the positioning plate 204 and the arc-shaped fixing plate 201. A spring is fitted on the surface of the fixing rod 205. One end of the spring is welded and fixed to the limiting block at the top of the fixing rod 205, and the other end is welded and fixed to the side of the connecting block 203. The spring is always in a stretched state. Through the elastic tension of the spring, the fixing rod 205 can be firmly pressed into the positioning hole to prevent the fixing rod 205 from loosening during pipeline operation.

[0028] The connecting pipe 1, located on the inner wall of the pipe below the arc-shaped fixing plate 201, has an annular groove 206. The width and depth of the annular groove 206 are adapted to the thickness and edge height of the stainless steel filter screen 207. The stainless steel filter screen 207 can be directly removed or inserted into the annular groove 206 along the axial direction of the connecting pipe 1. The aperture of the filter screen 207 is set according to the characteristics of impurities in the liquid being transported in the pipeline, ensuring that it can effectively intercept solid impurities without excessively obstructing the flow of liquid. The stainless steel material can prevent the filter screen 207 from rusting due to long-term contact with sewage, thus extending its service life.

[0029] Working principle:

[0030] In this embodiment, when the pipeline is in use, liquid flows from the first PVC pipe 102 into the connecting pipe 1. When it passes through the stainless steel filter screen 207, impurities are intercepted by the filter screen 207, and the filtered liquid flows out through the second PVC pipe 103. When it is necessary to clean the filter screen 207, pull the fixing rod 205 to disengage it from the positioning hole of the locking plate 204, and then slide the arc fixing plate 201 to remove the filter screen 207 from the annular groove 206 for cleaning. After cleaning, reinstall the filter screen 207, slide the arc fixing plate 201 in the opposite direction to the closed state, release the fixing rod 205, and under the action of the spring, the fixing rod 205 is inserted into the positioning hole to complete the maintenance.
