Description

Technical Field

[0001] This utility model relates to the field of buried pipe technology, and in particular to an anti-vibration buried pipe. Background Technology

[0002] As shown in patent application number CN202320537207.7, conventional buried pipes on the market include a pipe body with a socket at one end and a plug at the other end. When two adjacent buried pipes are connected, the plug of one buried pipe is inserted into the socket of the other buried pipe, and the plug and socket are sealed by a sealing ring. Although the above connection method is simple, its vibration resistance is poor. After the buried pipe is subjected to vibration, the plug and socket are prone to axial relative displacement, resulting in leakage. Utility Model Content

[0003] To address the shortcomings of existing buried pipes in terms of poor vibration resistance, this invention proposes a buried pipe that improves vibration resistance and prevents leakage after vibration.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An anti-vibration buried pipe includes a pipe body, main impellers, a first sealing ring, a ferrule, and a first transition impeller. Multiple main impellers are fixedly connected to the outside of the pipe body along its length. One end of the pipe body has a socket section. The first sealing ring is installed inside the socket section. The ferrule includes an annular first connecting portion, a first deformable portion, and a first clamping head. The inner side of the first connecting portion is fixedly connected to the outer circumferential surface of the outer end of the socket section. The outer side of the first connecting portion is inclined away from the pipe body and fixedly connected to one side of the first deformable portion. The first deformable portion… The other side extends horizontally away from the pipe body and is fixedly connected to the first clamp head on the inner side. The thickness of the first deformed part is less than the thickness of the pipe body. The other end of the pipe body is provided with a spigot pipe section that can be inserted into the socket pipe section and sealed with the first sealing ring. The first transition impeller is fixedly connected to the outer periphery of the spigot pipe section. The outer diameter of the first transition impeller is less than or equal to the inner diameter of the first clamp head and less than the outer diameter of the main impeller. When the spigot pipe section is inserted into the socket pipe section, the first transition impeller abuts against the first connecting part, and the first clamp head is located on the back of the first transition impeller.

[0005] With the above settings, firstly, after the spigot pipe section is inserted into the socket pipe section of the adjacent buried pipe, the connection between the two adjacent buried pipes can be completed, which is convenient. Secondly, after the soil is backfilled on the upper side of the buried pipe, under the action of soil pressure, the first clamp head automatically locks the first transition impeller to prevent the spigot pipe section from being pulled out.

[0006] Furthermore, the buried pipe also includes a second transition impeller fixedly connected to the outer periphery of the socket pipe section. The second transition impeller is located on the side of the first transition impeller close to the main impeller. The outer diameter of the second transition impeller is between the outer diameters of the first transition impeller and the main impeller. The ferrule also includes a second connecting part, a second deformable part, and a second clamping head, all of which are annular. The side of the first deformable part away from the first connecting part is fixedly connected to the inner side of the second connecting part. The outer side of the second connecting part is inclined away from the pipe body and fixedly connected to one side of the second deformable part. The other side of the second deformable part extends horizontally away from the pipe body and is fixedly connected to the second clamping head on the inner side. The thickness of the second deformable part is less than the thickness of the pipe body. The inner diameter of the second clamping head is greater than or equal to the outer diameter of the second transition impeller. When the socket pipe section is inserted into the socket pipe section, the second clamping head is located on the back of the second transition impeller.

[0007] The above settings further enhance the vibration resistance of buried pipes.

[0008] Furthermore, the buried pipe also includes a second sealing ring embedded between the first transition impeller and the second transition impeller. When the spigot pipe section is inserted into the socket pipe section, the second sealing ring abuts against the second connection part.

[0009] The above settings further enhance the sealing performance of buried pipe connections.

[0010] Furthermore, a first support surface perpendicular to the outer wall of the tube is provided on the side of the first transition impeller near the middle of the tube body, and the first support surface extends to the outer peripheral surface of the first transition impeller.

[0011] The above settings improve the locking effect between the first card head and the first transition impeller.

[0012] Furthermore, a second support surface perpendicular to the outer wall of the tube is provided on the side of the second transition impeller near the middle of the tube body, and the second support surface extends to the outer peripheral surface of the second transition impeller.

[0013] The above settings improve the locking effect between the second card head and the second transition impeller.

[0014] Furthermore, the outer end of the socket pipe section is fixedly connected with an annular protrusion along its outer periphery. The ferrule also includes an annular locking part, which is tightly gripped on the socket pipe section. The inner side of the locking part is provided with a groove that matches the annular protrusion. The annular protrusion is embedded in the groove. The inner side of the first connecting part is fixedly connected to the side of the locking part away from the pipe body. The ferrule is a split clamp structure and is locked to the end of the socket pipe section by fasteners.

[0015] Furthermore, the outer periphery of the socket pipe section bulges outward, and an installation groove is formed on the inner side of the socket pipe section, in which the first sealing ring is installed.

[0016] The above settings facilitate the installation of the first sealing ring and increase the ring stiffness of the socket pipe section by bulging outwards.

[0017] Furthermore, the buried pipe also includes reinforcing ribs fixedly connected to the outer periphery of the spigot pipe section. When the spigot pipe section is inserted into the socket pipe section, the reinforcing ribs abut against the inner wall of the socket pipe section.

[0018] The above settings prevent radial movement of the spigot segment within the socket segment, further improving the sealing and reliability of the connection between the spigot and socket segments.

[0019] Furthermore, the main impeller has a hollow annular structure, with an annular groove formed by the circumferential inward concavity on the outer side of the main impeller, and two convex ribs formed on the left and right sides of the annular groove on the outer side of the main impeller.

[0020] The above settings improve the feel of the buried pipe, increase the contact area between the buried pipe and the soil, and reduce soil erosion and settlement of the buried pipe.

[0021] Furthermore, the outer side of the rib is recessed inward to form multiple grooves arranged circumferentially, the depth of which is less than the depth of the annular groove.

[0022] The above settings improve the ring flexibility of buried pipes. Attached Figure Description

[0028] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0029] like Figures 1 to 5An anti-vibration buried pipe includes a pipe body 3, main impellers 4, a first sealing ring 5, a clamping sleeve 6, and a first transition impeller 7. Multiple main impellers 4 are fixedly connected to the outside of the pipe body 3 along its length. A socket pipe section 8 is provided at one end of the pipe body 3. The first sealing ring 5 is installed inside the socket pipe section 8. The clamping sleeve 6 includes a first connecting part 61, a first deformable part 62, and a first clamping head 63, all of which are annular. The inner side of the first connecting part 61 is fixedly connected circumferentially to the end face of the socket pipe section 8. The outer side of the first connecting part 61 is inclined away from the pipe body 3 and fixedly connected to one side of the first deformable part 62. The other side of 62 extends horizontally away from the tube body 3 and is fixedly connected to the first clamp head 63 on the inner side. The thickness of the first deformable part 62 is less than the thickness of the tube body 3. The other end of the tube body 3 is provided with a spigot tube section 9 that can be inserted into the socket tube section 8 and sealed with the first sealing ring 5. The first transition impeller 7 is fixedly connected to the outer periphery of the spigot tube section 9. The outer diameter of the first transition impeller 7 is less than or equal to the inner diameter of the first clamp head 63 and less than the outer diameter of the main impeller 4. When the spigot tube section 9 is inserted into the socket tube section 8, the first transition impeller 7 abuts against the first connecting part 61, and the first clamp head 63 is located on the back of the first transition impeller 7.

[0030] With the above settings, firstly, after the spigot pipe segment 9 is inserted into the socket pipe segment 8 of the adjacent buried pipe, the connection between the two adjacent buried pipes can be completed, which is convenient. Secondly, after the soil is backfilled on the upper side of the buried pipe, under the action of soil pressure, the first clamp head 63 automatically clamps the first transition impeller 7 to prevent the spigot pipe segment 9 from being pulled out.

[0031] The pipe body 3 of this application is basically a circular pipe structure. Multiple main impellers 4 are evenly arranged along the length of the pipe body 3. Each main impeller 4 is arranged in a ring structure along the outer circumference of the pipe body 3. The main impellers 4 increase the ring stiffness of the pipe body 3 and reduce the deformation of the buried pipe underground. A first transition impeller 7 is provided at the spigot section 9. The outer diameter of the first transition impeller 7 is smaller than the outer diameter of the main impeller 4, that is, the height of the first transition impeller 7 is smaller than the height of the main impeller 4. The first transition impeller 7 plays a transitional role, facilitating production and improving the stability of the buried pipe. When the clamping sleeve 6 is composed of a first connecting part 61, a first deformable part 62, and a first clamping head 63, the cross-section of the clamping sleeve 6 is basically a "F" shape. When two adjacent buried pipes are connected, the spigot section 9 of one buried pipe is inserted into the socket section 8 of another buried pipe. The first transition impeller 7 abuts against the first connecting part 61, indicating that the spigot section 9 is inserted in place. Figure 1 At this time, the first sealing ring 5 is located between the socket pipe section 8 and the spigot pipe section 9 to prevent water leakage. The inner diameter of the first clamping head 63 is greater than or equal to the outer diameter of the first transition impeller 7. During the insertion of the spigot pipe section 9 into the socket pipe section 8, there is basically no interference between the first clamping head 63 and the first transition impeller 7. After backfilling the soil above the buried pipe, under the action of earth pressure, the first deformation part 62 deforms towards the first transition impeller 7, such as... Figure 5The first clamp head 63 retracts inward, and the inner diameter of the first clamp head 63 is smaller than the outer diameter of the first transition impeller 7. When the buried pipe is vibrated and the spigot pipe section 9 moves outward, the first clamp head 63 abuts against the back of the first transition impeller 7 to prevent the spigot pipe section 9 from being pulled out and to ensure the connection effectiveness between two adjacent buried pipes.

[0032] As one implementation, the buried pipe also includes a second transition impeller 10 fixedly connected to the outer periphery of the socket pipe section 9. The second transition impeller 10 is located on the side of the first transition impeller 7 near the main impeller 4. The outer diameter of the second transition impeller 10 is between the outer diameters of the first transition impeller 7 and the main impeller 4. The ferrule 6 also includes a second connecting part 64, a second deformable part 65, and a second locking head 66, all of which are annular. The side of the first deformable part 62 away from the first connecting part 61 is fixedly connected to the inner side of the second connecting part 64. The outer side of the second connecting part 64 is inclined away from the pipe body 3 and is fixedly connected to one side of the second deformable part 65. The other side of the second deformable part 65 extends horizontally away from the pipe body 3 and is fixedly connected to the inner side of the second locking head 66. The thickness of the second deformable part 65 is less than the thickness of the pipe body 3. The inner diameter of the second locking head 66 is greater than or equal to the outer diameter of the second transition impeller 10. When the socket pipe section 9 is inserted into the socket pipe section 8, the second locking head 66 is located on the back of the second transition impeller 10.

[0033] The above settings further enhance the vibration resistance of buried pipes.

[0034] In the buried pipe of this application, a second transition impeller 10 is added between the first transition impeller 7 and the main impeller 4. The height of the second transition impeller 10 is between the first transition impeller 7 and the main impeller 4, thereby reducing the height difference between the first transition impeller 7 and the second transition impeller 10, as well as between the second transition impeller 10 and the main impeller 4, and further improving the stability of production. When the spigot pipe section 9 is inserted into the socket pipe section 8, there is no interference between the second clamping head 66 and the second transition impeller 10. After the soil rebounds on the upper side of the buried pipe, under the action of earth pressure, the second deformation part 65 deforms towards the second transition impeller 10, and the inner diameter of the second clamping head 66 shrinks. When the buried pipe is vibrated, the first clamping head 63 and the second clamping head 66 work together to resist the pull-out force of the spigot pipe section 9.

[0035] As one implementation method, the buried pipe also includes a second sealing ring 11 embedded between the first transition impeller 7 and the second transition impeller 10. When the spigot pipe section 9 is inserted into the socket pipe section 8, the second sealing ring 11 abuts against the second connecting part 64.

[0036] The above settings further enhance the sealing performance of buried pipe connections.

[0037] The second sealing ring 11 is installed using the groove naturally formed between the first transition impeller 7 and the second transition impeller 10. When the spigot pipe section 9 is inserted into the socket pipe section 8, the outer side of the second sealing ring 11 abuts against the second connecting part 64. The first sealing ring 5 and the second sealing ring 11 form two waterproof lines, improving the sealing performance.

[0038] As one implementation, the first transition impeller 7 is provided with a first support surface 12 perpendicular to the outer wall of the tube body 3 on the side near the middle of the tube body 3, and the first support surface 12 extends to the outer peripheral surface of the first transition impeller 7.

[0039] The above settings enhance the locking effect between the first card head 63 and the first transition impeller 7.

[0040] As one implementation, the second transition impeller 10 is provided with a second support surface 13 perpendicular to the outer wall of the tube body 3 on the side near the middle of the tube body 3, and the second support surface 13 extends to the outer peripheral surface of the second transition impeller 10.

[0041] The above settings enhance the locking effect between the second card head 66 and the second transition impeller 10.

[0042] As one implementation, an annular protrusion 19 is fixedly connected to the outer end of the socket pipe section along the outer periphery. The ferrule also includes an annular locking part 67, which is clamped on the socket pipe section. A groove adapted to the annular protrusion is provided on the inner side of the locking part. The annular protrusion is embedded in the groove. The inner side of the first connecting part is fixedly connected to the side of the locking part away from the pipe body. The ferrule is a split clamp structure and is locked to the end of the socket pipe section 8 by fasteners 22.

[0043] The above settings facilitate the installation and construction of the card sleeve.

[0044] The ferrule of this application can be made of metal or plastic. The ferrule is a split clamp structure, that is, the ferrule can be divided into two semi-annular clamps with the same structure. Each clamp includes half of a locking part, half of a first connecting part, half of a first deforming part, half of a first clamping head, half of a second connecting part, half of a second deforming part and half of a second clamping head. The two clamps are installed on the socket pipe section to form a closed loop structure. The two ends of the two clamps are locked together by fasteners to form the above-mentioned annular ferrule.

[0045] As one implementation method, the outer periphery of the socket pipe section 8 protrudes outward, and an installation groove 14 is formed on the inner side of the socket pipe section 8, in which the first sealing ring 5 is installed.

[0046] The above settings facilitate the installation of the first sealing ring 5, and increase the ring stiffness of the socket pipe section 8 by bulging outward.

[0047] As one implementation method, the buried pipe also includes a reinforcing rib 15 fixedly connected to the outer periphery of the spigot pipe section 9. When the spigot pipe section 9 is inserted into the socket pipe section 8, the reinforcing rib 15 abuts against the inner wall of the socket pipe section 8.

[0048] The above-mentioned design prevents radial movement of the spigot segment 9 within the socket segment 8, further enhancing the sealing and reliability of the connection between the spigot segment 9 and the socket segment 8.

[0049] As one implementation method, the main impeller 4 has a ring-shaped hollow structure. The outer side of the main impeller 4 is concave inward to form an annular groove 16, and two convex ribs 17 are formed on the left and right sides of the annular groove 16 on the outer side of the main impeller 4.

[0050] The above settings improve the feel of the buried pipe, increase the contact area between the buried pipe and the soil, and reduce soil erosion and settlement of the buried pipe.

[0051] While existing buried pipes meet the ring stiffness requirements, their crests are basically arc-shaped. When the buried pipes arrive at the construction site, quality inspectors will press down on the crests with their fingers, and the crests will easily sink, giving the illusion of poor ring stiffness. In this application, an annular groove 16 is set on the outer side of the main impeller 4, forming a raised rib 17. When quality inspectors press down on the main impeller 4, the annular groove 16 is not easily collapsed, and the raised rib 17 also plays a supporting role, making it even less likely to collapse. This improves the overall feel of the buried pipe, giving the impression of greater ring stiffness. In addition, the setting of the annular groove 16 increases the outer surface area of ​​the main impeller 4. When the buried pipe is buried underground, the contact area with the soil is larger, which can reduce soil erosion and thus reduce the settlement of the buried pipe.

[0052] As one implementation, the outer side of the rib 17 is recessed inward to form multiple grooves 18 arranged circumferentially, and the depth of the grooves 18 is less than the depth of the annular groove 16.

[0053] The above settings improve the ring flexibility of buried pipes.

[0054] Specifically, after the groove 18 is set on the rib 17, the rib 17 is basically wavy, which can better disperse the soil pressure and improve the flexibility of the buried pipe ring.

[0055] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
