Description

Technical Field

[0001] The utility model relates to the technical field of MPP power pipes, in particular to an MPP power pipe connection structure. Background Art

[0002] MPP power pipe, also known as MPP power cable protection pipe or MPP cable protection pipe, is available in trenchless and trenchless types. MPP trenchless power pipe is also known as MPP jacking pipe or dragging pipe. MPP pipe is primarily made of modified polypropylene. It is resistant to high temperatures and external pressures and is suitable for medium and low voltage transmission line cable conduit up to 10 kV.

[0003] During the installation process, existing MPP power pipes are usually connected in series by hot melt welding. Hot melt welding requires corresponding hot melt equipment and has low welding efficiency. In addition, the joints are prone to cracking, resulting in poor connection firmness.

[0004] Patent publication number CN217087418U discloses an MPP power pipe with a quick-connect structure. Two pipes are connected via a quick-connect sleeve, and a limiting structure limits the position of the pipe body on the quick-connect sleeve to prevent easy detachment and improve installation security. By dividing the quick-connect sleeve into two, quick-connect sleeve 1 and quick-connect sleeve 2, the quick-connect sleeve and the pipe body can be easily connected. At the same time, the provision of a clamping structure enables quick-connect sleeve 1 and quick-connect sleeve 2 to be quickly connected, and the connection is highly stable and not easily detached. However, its clamping structure is a one-way clamping structure. When the internal cable needs to be repaired, it is necessary to use a tool to pry the side wall of the positioning groove to remove the pipe, which is time-consuming and labor-intensive, and can easily cause the side wall of the positioning groove to break.

[0005] Therefore, it is necessary to develop an MPP power pipe connection structure to address the above defects. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0037] In a specific embodiment of the present invention, Figures 1 to 6 As shown, it includes an MPP tube body 1 and a first semicircular sleeve 2 and a second semicircular sleeve 3 located at the joint of two adjacent MPP tube bodies 1. The inner walls at both ends of the first semicircular sleeve 2 are respectively clamped with the two MPP tube bodies 1, and the inner walls at both ends of the second semicircular sleeve 3 are respectively clamped with the two MPP tube bodies 1. A male block 4 is fixed on the first semicircular sleeve 2, and a female block 5 is fixed on the second semicircular sleeve 3. The male block 4 is plugged into the female block 5, and an elastic telescopic component is slidably installed in the male block 4. A slot 501 is opened on one side of the female block 5, and one end of the elastic telescopic component protrudes from the male block 4 and is clamped with the slot 501.

[0038] Specifically, the insertion of male and female connectors 4 and 5, and the engagement of the elastic expansion assembly with the slot 501, enable quick connection of adjacent MPP tubes. A tool is inserted into the slot 501 and the elastic expansion assembly is pushed. The elastic expansion assembly contracts, freeing it from engagement with the slot 501, allowing the first and second semicircular sleeves 2 and 3 to be removed.

[0039] Two male blocks 4 are provided and are located on both sides of the first semicircular sleeve 2 respectively. Two female blocks 5 are provided and are located on both sides of the second semicircular sleeve 3 respectively. A slot 502 is provided on the side of the female block 5 close to the male block 4. A protruding portion 401 is provided at the bottom end of the male block 4, and the protruding portion 401 is inserted into the slot 502; the elastic telescopic component is arranged in the protruding portion 401.

[0040] The elastic telescopic component includes a slide plate 6 and a tension spring 7. A first slide groove 402 for accommodating the slide plate 6 is provided on the side of the protruding portion 401 away from the first semicircular sleeve 2, and the slide plate 6 slides in cooperation with the first slide groove 402. Second slide grooves 403 connected to the first slide groove 402 are provided on both sides of the protruding portion 401. Ear plates 601 are fixed at both ends of the slide plate 6, and the ear plates 601 are located on the side close to the first semicircular sleeve 2. The ear plates 601 slide in cooperation with the second slide groove 403, and the tension spring 7 is arranged between the slide plate 6 and the bottom wall of the first slide groove 402; the clamping groove 501 is provided on the side of the female head block 5 away from the second semicircular sleeve 3, and one end of the slide plate 6 protrudes from the first slide groove 402 and is clamped with the clamping groove 501.

[0041] Specifically, "the first slide groove 402 accommodating the slide 6" means that the slide 6 can fully enter the first slide groove 402. The lug 601 cooperates with the second slide groove 403 to limit the slide 6 and prevent it from falling out of the first slide groove 402. The tension spring 7 is used to provide an outward elastic force on the slide 6, ensuring that one end of the slide 6 can be engaged with the locking groove 501.

[0042] At least one notch 602 is provided on the side of the slide plate 6 close to the first semicircular sleeve 2. The notch 602 is arranged in a one-to-one correspondence with the tension spring 7. One end of the tension spring 7 is fixedly connected to the bottom wall of the notch 602, and the other end of the tension spring 7 is fixedly connected to the bottom wall of the first slide groove 402.

[0043] A sealing gasket 8 is provided at the butt joint surface between the first semicircular sleeve 2 and the second semicircular sleeve 3 .

[0044] Grooves are respectively provided on the outer walls of both ends of the MPP pipe body 1 . The grooves are located in the cavity formed by the first semicircular sleeve 2 and the second semicircular sleeve 3 . A sealing ring 9 is provided in the grooves.

[0045] Annular grooves 101 are provided on the outer walls of both ends of the MPP pipe body 1, and semicircular clamping rings 10 matching the annular grooves 101 are fixed on the inner walls of the first semicircular sleeve 2 and the second semicircular sleeve 3, respectively. Two semicircular clamping rings 10 are provided on the first semicircular sleeve 2 and the second semicircular sleeve 3 at intervals. The two semicircular clamping rings 10 of the first semicircular sleeve 2 are respectively clamped with the annular grooves 101 on the two adjacent MPP pipe bodies 1, and the two semicircular clamping rings 10 of the second semicircular sleeve 3 are respectively clamped with the annular grooves 101 on the two adjacent MPP pipe bodies 1.

[0046] The working principle of the MPP power pipe connection structure of the present invention is as follows: sealing rings 9 are placed on both ends of the MPP pipe body 1, the ports of the two adjacent MPP pipe bodies 1 are aligned, a sealing gasket 8 is placed between the first semicircular sleeve 2 and the second semicircular sleeve 3, the slide 6 is pushed into the first sliding groove 402, the first semicircular sleeve 2 and the second semicircular sleeve 3 are clamped to the two adjacent MPP pipe bodies 1 through the annular groove 101 and the semicircular clamping ring 10, and the protruding portion 401 is inserted into the slot 502. When the slide 6 is aligned with the clamping groove 501, the elastic force of the tension spring 7 is applied to the slide 6 at one end to clamp with the clamping groove 501, thus completing the connection between the two adjacent MPP pipe bodies 1. When disassembly is required, a tool (such as a screwdriver) is used to probe into the clamping groove 501 and push the slide 6 until the slide 6 is completely inserted into the first sliding groove 402. The slide 6 is no longer clamped with the clamping groove 501, and the first semicircular sleeve 2 and the second semicircular sleeve 3 can be disassembled.
