Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of MPP pipes, and particularly relates to an MPP pipe with wear-resistant inner wall. Background Technique
[0002] MPP pipes are a kind of polymer pipe materials, which are widely used in the fields of electric power, communication, water supply and drainage, etc. The MPP pipes show relatively weak compressive capacity when dealing with external impacts. This defect directly leads to the pipes being easily damaged, not only reducing their due service life, but also invisibly increasing the costs of maintenance and replacement, bringing unnecessary economic burdens to users; in addition, in the actual application of MPP pipes, if the internal cables fail to achieve a scientific and reasonable isolation layout, it will bring great inconvenience to the classification management and maintenance of the cables. The cable environment lacking effective isolation is prone to cable entanglement and chaos, which not only increases the complexity and difficulty of the maintenance work, but also may cause signal interference between different cables, seriously affecting the clarity and stability of signal transmission, and then may interfere with the normal operation of the entire system. The inner wall wear-resistant performance of the existing MPP pipes is not good, which leads to increased wear during the use of the pipes, and then seriously shortens the overall service life of the pipes, posing a great challenge to the long-term stable operation of the pipes. Therefore, we propose an MPP pipe with wear-resistant inner wall. Content of the Utility Model

[0030] The anti-compression mechanism 5 includes an anti-compression layer 51. A plurality of buffer cavities 52 are formed inside the anti-compression layer 51. A buffer mechanism 53 is arranged inside each of the plurality of buffer cavities 52. A shielding layer 54 is fixedly connected to the inner wall of the inner layer of the anti-compression layer 51, and the inner wall of the shielding layer 54 is fixedly connected to the outer surface of the MPP power pipe 1. The outer wall of the inner layer of the anti-compression layer 51 is fixedly connected to the inner wall of the waterproof layer 6.
[0031] In this embodiment, the buffer mechanism 53 includes buffer sheets 531. There are two buffer sheets 531. Elastic sheets 532 are fixedly connected together between the left parts and the right parts of the opposite surfaces of the two buffer sheets 531. Connecting sheets 533 are fixedly connected to the inner walls of the two buffer sheets 531. A number of springs 534 are fixedly connected to the opposite surfaces of the two connecting sheets 533. Fixed sheets 535 are fixedly connected together between the upper ends of the upper number of springs 534 and between the lower ends of the lower number of springs 534. The two buffer sheets 531 are both arranged in an arc structure, and the middle parts of the opposite surfaces of the two buffer sheets 531 are in contact with each other. A number of buffer cavities 52 are all arranged in an elliptical structure, and a number of fixing grooves 2 are all arranged in a T-shaped structure.
[0032] Through the above solution: By means of the compression-resistant layer 51 cooperating with a number of buffer cavities 52 provided inside it, the impact received by the outside of the MPP pipe can be initially buffered. Then, through the elasticity of the buffer sheets 531 and the elastic sheets 532, the impact force received by the MPP pipe can be buffered for the second time. Furthermore, through the elasticity of a number of springs 534, the efficient buffering of the impact force can be achieved, that is, the compressive capacity shown by the entire MPP pipe when dealing with external impacts can be improved, thereby prolonging the service life of the MPP pipe, making the MPP pipe not easily damaged, reducing the maintenance and replacement costs of the MPP pipe, and also reducing the economic burden on users. Finally, the shielding layer 54 can play an electromagnetic shielding role.

This not only facilitates the subsequent inspection and maintenance of the cables 4 but also reduces the complexity and difficulty of the inspection work. Moreover, signal interference is not likely to occur between the separated multiple cables 4, ensuring the clarity and stability of signal transmission and enabling the normal operation of the entire system.
[0035] It should be noted that during use, first, through the wear-resistant outer layer 7 and several wear-resistant rings 8 fixed on its outer surface, the wear resistance of the outside of the MPP pipe can be improved. Then, through the waterproof layer 6, the waterproof performance of the MPP pipe can be enhanced. By means of the compression-resistant mechanism 5 and several buffer mechanisms 53 provided inside it, the compression-resistant and anti-collision performance of the MPP pipe can be strengthened, extending the service life of the MPP pipe. Through the partition mechanism 3, the interior of the MPP power pipe 1 can be divided into multiple spaces to achieve the classification management of multiple cables 4, and the separated multiple cables 4 are more orderly, facilitating the subsequent inspection and maintenance of the cables 4.
