Description

Technical Field

[0001] The utility model relates to the technical field of MPP power pipes, in particular to a high-pressure-resistant MPP power pipe. Background Art

[0002] MPP power pipes use modified polypropylene as the main raw material, and are resistant to high temperatures and external pressures. They are suitable for medium and low voltage transmission line and cable conduit pipes. When using MPP power pipes to lay pipelines and cables in special areas such as roads, railways, buildings, and riverbeds, there is no need for large-scale dredging, excavation, or damage to the road surface, and the dust and road congestion caused by traditional construction can be eliminated.

[0003] For example, an MPP power pipe disclosed in the utility model with authorization announcement number CN216489528U can strengthen the main strength of the MPP pipe body by arranging a reinforcing pipe inside the MPP pipe body. The overall strength of the device can be improved by screwing threaded pipe 2 to the inner side of adjacent connecting ring 2 and screwing threaded pipe 1 to the inner side of connecting ring 1. The device is screwed to the external structure through multiple bolts, and the installation can be completed by passing the cables between the multiple reinforcing pipes. When the connection vibrates, the vibration will be transmitted along the side wall of the installation bolt to the spring for buffering, thereby preventing the connection from loosening.

[0004] This prior art also has the following problems when used:

[0005] After the reinforcing tube of the device is inserted into the inner side of the MPP tube body, the reinforcing tube is rotated so that the threaded tube 1 and the threaded tube 2 are respectively screwed onto the inner sides of the adjacent connecting ring 1 and the connecting ring 2. When the reinforcing tube is long, the friction between the reinforcing tube and the MPP tube body is too large, which makes it difficult to rotate the reinforcing tube, making it inconvenient to install the reinforcing tube.

A wear-resistant layer 6 is provided between the MPP pipe body 1 and the reinforcement pipe 7. The wear-resistant layer 6 is made of common wear-resistant materials and is adhered to the inside of the reinforcement pipe 7. The wear-resistant layer 6 can prevent the MPP pipe body 1 and the reinforcement pipe 7 from wearing each other. An anti-corrosion layer 2 is provided on the outside of the reinforcement pipe 7, and the anti-corrosion layer 2 is made of PVC waterproof coiled material. A symmetrical first threaded ring 4 is fixedly provided on the outside of the MPP pipe body 1, and a first threaded sleeve 3 is threadedly connected to the outside of the first threaded ring 4. An annular plate 5 is fixedly provided on the side of the first threaded sleeve 3 close to each other. A first annular groove adapted to the annular plate 5 is provided on the left and right sides of the reinforcement pipe 7. The annular plate 5 is movably connected to the reinforcement pipe 7 through the first annular groove. After the MPP pipe body 1 is inserted into the inner side of the reinforcement pipe 7, the reinforcement pipe 7 is inserted into the inner side of the anti-corrosion layer 2, and the first threaded sleeve 3 is rotated to thread the first threaded sleeve 3 and the first threaded ring 4 until the annular plate 5 is engaged with the inside of the first annular groove. At this time, the first threaded sleeve 3 is in close contact with the anti-corrosion layer 2 and the reinforcement pipe 7, so that the reinforcement pipe 7 can be installed, and the installation difficulty is relatively low.

[0025] like Figures 1-4 As shown, a mounting assembly is provided on the outside of the reinforcement assembly, and the mounting assembly consists of a second threaded ring 8, a second threaded sleeve 9, a swivel 10, a fixed rod 11, a connecting rod 12, an arc-shaped pressure plate 13 and a U-shaped rod 18. A symmetrical second threaded ring 8 is fixedly provided on the outside of the anti-corrosion layer 2, and a second threaded sleeve 9 is threadedly connected to the outside of the second threaded ring 8. A swivel 10 is provided on the outside of the second threaded sleeve 9, and a second annular groove adapted to the swivel 10 is provided on the outside of the second threaded sleeve 9.

[0026] like Figures 1-4 As shown, a plurality of rubber anti-skid pads 14 are provided on the outside of the MPP tube body 1, and an insert rod 15 is fixedly provided on the side of the rubber anti-skid pad 14 close to the arc pressure plate 13.

[0028] When the device is used, the MPP tube body 1 is inserted into the inner side of the reinforcement tube 7, and the reinforcement tube 7 is inserted into the inner side of the anti-corrosion layer 2. The first threaded sleeve 3 is rotated to make the first threaded sleeve 3 threadedly connected with the first threaded ring 4 until the annular plate 5 is engaged with the inside of the first annular groove. At this time, the first threaded sleeve 3 is tightly attached to the anti-corrosion layer 2 and the reinforcement tube 7, so that the reinforcement tube 7 can be installed. The installation difficulty is relatively low. When the MPP tube body 1 needs to be connected to the external structure, the external structure is placed between the inner sides of the arc-shaped pressure plate 13, and the second threaded sleeve is rotated at the same time. 9 drives the second threaded sleeve 9 to approach each other, and the rotation of the second threaded sleeve 9 drives the swivel 10 to approach each other, thereby driving the fixed rod 11, the connecting rod 12 and the arc-shaped pressure plate 13 to approach each other, and the rubber anti-slip pad 14 contacts the external structure to drive the limit plate 16 away from the arc-shaped pressure plate 13, and the return spring 17 is stretched to avoid the external structure being squeezed and damaged due to direct contact of the arc-shaped pressure plate 13, until the inner side of the arc-shaped pressure plate 13 is close to the external structure, which facilitates the connection between the MPP pipe body 1 and the external structure and has strong applicability.
