Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a PE lining pipe for pipeline lining repair. Background Technology

[0002] Existing repair liner pipes all rely on a first elastic element to drive a screw to rotate, causing the first and second limiting blocks to move away from each other. This allows the support plate to better support the pipe body, thus fixing both ends of the flexible liner pipe to the repair pipe wall. However, when the friction between the screw and the limiting blocks is high, it is difficult to drive the screw to rotate using only the first elastic element. For example, the drainage pipe repair liner pipe disclosed in Chinese Patent Application No. CN202222821363.4, although it achieves the purpose of fixing both ends of the flexible liner pipe to the repair pipe wall, preventing water flow from eroding and damaging the ends of the liner pipe and improving the service life of the pipe, it is difficult to overcome the friction between the screw and the limiting blocks and drive the screw to rotate using only the first elastic element to achieve the effect of opening the support plate. It is easy for the elastic element to fail to drive the screw to rotate, resulting in the device failing to achieve the desired effect and limiting its use. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a PE inner lining pipe for pipe lining repair. It uses a fixing ring with a diameter larger than the pipe body. When the inner lining pipe is installed, the fixing ring is used to scrape off some of the material adsorbed on the inner wall of the pipe, reducing the damage to the pipe body caused by some material on the pipe. After the pipe body expands, the two fixing rings move with the pipe body. At the same time, the spring pushes the fixing plate so that the fixing block can be inserted into the slot, fixing the distance between the two fixing rings and making the surface fit against the inner wall of the pipe. This enhances the fixing effect between the inner lining pipe and the inner wall of the pipe, and prevents water flow from pushing the inner lining pipe from both ends of the pipe body, thus improving the fixing effect of the inner lining pipe.

[0004] This utility model also provides a PE lining pipe for pipe lining repair as described above, comprising: a pipe body, a fixing ring two fixedly connected to the inner side wall of the pipe body, a fixing plate fixedly connected to the side surface of the fixing ring two, a spring one fixedly connected to the bottom wall of the fixing plate, a fixing block fixedly connected to the end of the spring one away from the fixing plate, a fixing ring one fixedly connected to the side surface of the fixing ring two, a slot provided on the inner side wall of the fixing ring one, and a spring two fixedly connected to the inner side wall of the fixing ring two;

[0005] The pipe body includes a wear-resistant layer, a PE layer is fixedly connected to the side surface of the wear-resistant layer, and a heat-resistant layer is fixedly connected to the side surface of the PE layer. Using these components, a fixing ring is used to scrape away some of the material adsorbed inside the pipe, reducing damage to the pipe body caused by the material. Then, by inserting a fixing block into a slot, fixing ring one and fixing ring two are fitted to the inner wall of the pipe, enhancing the fixing effect between the inner liner and the pipe.

[0006] According to the PE lining pipe for pipe lining repair described in this utility model, connecting blocks are fixedly connected to the side surfaces of both the first fixing ring and the second fixing ring, and the side surfaces of the connecting blocks are fixedly connected to the pipe body. The connecting blocks are used to fix the first fixing ring and the second fixing ring to the pipe body.

[0007] According to the PE lining pipe for pipe lining repair described in this utility model, the upper surface of the fixing plate is provided with a placement groove, and the fixing block is located inside the placement groove during operation. This is for placing the fixing block.

[0008] According to the PE lining pipe for pipe lining repair described in this utility model, a sliding ring is fixedly connected to the side surface of the fixing block, and the side surface of the sliding ring is slidably connected to the fixing plate. The sliding ring is used to prevent the fixing block from completely detaching from the placement groove.

[0009] According to the PE lining pipe for pipe lining repair described in this utility model, a sliding groove is provided on the inner side wall of the fixing ring, and the fixing plate is located inside the sliding groove. This allows the fixing plate to slide along the fixing ring inside the sliding groove.

[0010] According to the PE lining pipe for pipe lining repair described in this utility model, the end of the second spring away from the first fixing ring is fixedly connected to the fixing plate, and the side surface of the fixing plate is slidably connected to the first fixing ring. The elastic force of the second spring pushes the fixing plate to slide against the inner wall of the first fixing ring.

[0011] According to the PE lining pipe for pipe lining repair described in this utility model, a limiting block is slidably connected to the inner wall of the fixing ring one, and a positioning hole is provided on the side surface of the fixing plate. During operation, the end of the limiting block near the fixing ring one extends into the positioning hole. The position of the fixing plate is fixed by inserting the limiting block into the positioning hole, and the fixing plate can only slide after the limiting block is pulled out.

[0012] According to the PE lining pipe for pipe lining repair described in this utility model, the end of the fixing block away from the fixing plate extends into the slot during operation, and the end of the heat-resistant layer away from the PE layer is fixedly connected to the connecting block during operation. By inserting the fixing block into the slot, the distance between fixing ring one and fixing ring two is fixed, and the fixing ring one and fixing ring two are used to enhance the fixing effect of the pipe body by adhering to the pipe wall to be repaired after the pipe body is opened. Beneficial effects

[0013] Compared with existing technologies, using fixing rings with a diameter larger than that of the pipe body allows for the scraping off of some substances adhering to the inner wall of the pipe during installation of the inner liner, reducing damage to the pipe body caused by some substances on the pipe. After the pipe body expands, the two fixing rings move with the pipe body, while the spring pushes the fixing plate to allow the fixing block to be inserted into the slot, fixing the distance between the two fixing rings and ensuring that the surface of the fixing rings fits against the inner wall of the pipe. This enhances the fixing effect between the inner liner and the inner wall of the pipe and prevents water flow from pushing the inner liner from both ends of the pipe body, thus improving the fixing effect of the inner liner.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-6 The present invention relates to a PE lining pipe for pipe lining repair, comprising: a pipe body 1, a fixing ring 2 3 fixedly connected to the inner side wall of the pipe body 1, a fixing plate 7 fixedly connected to the side surface of the fixing ring 2 3, the side surface of the fixing plate 7 being slidably connected to the fixing ring 1 2, a spring 11 fixedly connected to the bottom wall of the fixing plate 7, a fixing block 10 fixedly connected to the end of the spring 11 away from the fixing plate 7, the end of the fixing block 10 away from the fixing plate 7 extending into the slot 6 during operation, a fixing ring 2 fixedly connected to the side surface of the fixing ring 2 3, a slot 6 provided on the inner side wall of the fixing ring 2 2, a spring 2 12 fixedly connected to the inner side wall of the fixing ring 2 3, the end of the spring 2 12 away from the fixing ring 1 2 being fixedly connected to the fixing plate 7;

[0025] Specifically, the diameters of fixing ring 1 and fixing ring 2 are larger than the inner diameter of pipe body 1. When pipe body 1 is inserted into the pipe to be repaired, fixing ring 1 and fixing ring 2 will first contact the inner wall of the pipe and scrape off some of the substances adsorbed on the inside of the pipe, reducing the damage to pipe body 1 caused by some substances on the pipe. After pipe body 1 is placed in a suitable position and expands, the limiting block 4 fixed on fixing ring 1 will be removed. At this time, fixing ring 1 and fixing ring 2 will open with pipe body 1, and spring 2 will push fixing plate 7 to move until fixing block 10 reaches slot 6. When fixing block 10 reaches slot 6, spring 11 will push fixing block 10 to insert into slot 6 to fix the position between fixing ring 1 and fixing ring 2, thereby making fixing ring 1 and fixing ring 2 fit against the inner wall of the pipe.

[0026] The pipe body 1 includes a wear-resistant layer 15, a PE layer 16 is fixedly connected to the side surface of the wear-resistant layer 15, a heat-resistant layer 17 is fixedly connected to the side surface of the PE layer 16, and the end of the heat-resistant layer 17 away from the PE layer 16 is fixedly connected to the connecting block 5 during operation.

[0027] Specifically, the pipe body 1 is divided into a wear-resistant layer 15, a PE layer 16, and a heat-resistant layer 17. The wear-resistant layer 15 is made of synthetic rubber, which has good wear resistance and impact resistance and can be used to reduce damage to the outside of the pipe body 1. The PE layer 16 is the central layer of the inner liner, which has good corrosion resistance, wear resistance, insulation, and good flexibility, and is suitable for various pipeline systems. The heat-resistant layer 17 is made of fluoroplastic, which has good high temperature resistance and chemical stability, giving the inner liner the effect of heat resistance and corrosion protection.

[0028] The upper surface of the fixing plate 7 is provided with a placement groove 8. The fixing block 10 is located inside the placement groove 8 during operation. A sliding ring 9 is fixedly connected to the side surface of the fixing block 10. The side surface of the sliding ring 9 is slidably connected to the fixing plate 7. A sliding groove 13 is provided on the inner side wall of the fixing ring 10. The fixing plate 7 is located inside the sliding groove 13.

[0029] Specifically, the inner wall of the fixing plate 7 is provided with a placement groove 8 for placing the fixing block 10. After the fixing block 10 reaches the slot 6, the internal spring 11 pushes the fixing block 10 out of the placement groove 8. The surface of the fixing block 10 is provided with a sliding ring 9. The sliding ring 9 can drive the fixing block 10 to slide along the inner wall of the sliding groove 13 and prevent the spring 11 from completely pushing the fixing block 10 out of the placement groove 8.

[0030] Both the side surfaces of the first fixed ring 2 and the second fixed ring 3 are fixedly connected with connecting blocks 5. The side surfaces of the connecting blocks 5 are fixedly connected to the tube body 1. The inner side wall of the first fixed ring 2 is slidably connected with a limiting block 4. The side surface of the fixed plate 7 is provided with a positioning hole 14. The end of the limiting block 4 near the first fixed ring 2 extends into the positioning hole 14 during operation.

[0031] Specifically, both the first fixed ring 2 and the second fixed ring 3 are provided with connecting blocks 5 on their sides. The connecting blocks 5 are inserted into the inner wall of the tube body 1 so that the first fixed ring 2 and the second fixed ring 3 are connected to the tube body 1 respectively. When the tube body 1 expands, the limiting block 4 is pulled out from the positioning hole 14. At this time, the distance between the first fixed ring 2 and the second fixed ring 3 will also increase as the tube body 1 expands, until the fixing block 10 is inserted into the slot 6.

[0032] Working principle: When in use, insert the tube body 1 into the pipe that needs to be repaired. Then, the fixing ring 1 2 and fixing ring 2 3 will first contact the inner wall of the pipe and scrape off some of the substances adsorbed on the inside of the pipe, reducing the damage to the tube body 1 caused by some substances on the pipe. After the tube body 1 is placed in the appropriate position, the tube body 1 expands. At the same time, the limiting block 4 fixed on the fixing ring 1 2 is removed. At this time, the fixing ring 1 2 and fixing ring 2 3 will open with the tube body 1, and the spring 2 12 will push the fixing plate 7 to move until the fixing block 10 reaches the slot 6. When the fixing block 10 reaches the slot 6, the spring 1 11 will push the fixing block 10 into the slot 6 to fix the position between the fixing ring 1 2 and fixing ring 2 3, so that the fixing ring 1 2 and fixing ring 2 3 fit against the inner wall of the pipe.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
