Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 4 , this embodiment provides the following technical solutions:

[0025] like Figure 1-Figure 3 As shown, a trenchless power pipe with a cable protection function includes: a first power pipe 1 and a second power pipe 101, one end of the first power pipe 1 and the second power pipe 101 are connected and installed with a first ring sleeve 102 and a second ring sleeve 108 respectively, the first ring sleeve 102 is rotatably sleeved on the outer surface of the second ring sleeve 108, and the upper and lower surfaces of the second ring sleeve 108 are provided with threaded holes, and a sealing locking mechanism 2 is installed with a threaded inner thread of the threaded hole of the second ring sleeve 108, and the sealing locking mechanism 2 can respectively contact the surfaces of the first ring sleeve 102 and the second ring sleeve 108.

[0026] A semi-arc groove 103 is formed at the transition between the upper and lower surfaces of the first ring sleeve 102 and the second ring sleeve 108 , and the sealing locking mechanism 2 can be threadedly advanced and contacted into the semi-arc groove 103 .

[0027] Sealing swivels 104 are fixedly mounted on the upper and lower ends of the inner wall of the first ring sleeve 102 . The sealing swivels 104 are rotatably mounted in sealing ring openings 105 . The sealing ring openings 105 are opened on the upper and lower ends of the outer surface of the second ring sleeve 108 .

[0028] A rotation opening 106 and an avoidance opening 107 are respectively provided at one end of the outer surface of the first ring sleeve 102 and the second ring sleeve 108. The rotation opening 106 of the first ring sleeve 102 allows the second power tube 101 to pass through it, and the avoidance opening 107 can avoid blocking the connecting opening of the first power tube 1 in the first ring sleeve 102.

[0029] Through the design of the first power tube 1, the second power tube 101, the first ring sleeve 102, the second ring sleeve 108, the sealing ring mouth 105 and the sealing locking mechanism 2, during the process of laying the MPP power tube, if an obstacle is encountered and the MPP power tube needs to be bent, the staff can point the rotating mouth 106 of the first power tube 1 in the direction in which the bending is required, and then the staff can push the second power tube 101 to drive the second ring sleeve 108 to rotate in the first ring sleeve 102 of the first power tube 1, and during the rotation process, the second power tube 101 will rotate in the rotating mouth 106 of the first ring sleeve 102, so that the opening angle of the rotating mouth 106 is the rotation angle of the first power tube 1 and the second power tube 101. This design allows the MPP power tube to be flexibly bent when encountering an obstacle, which is convenient for the staff. The direction of the pipeline is adjusted according to actual conditions to avoid laying difficulties caused by obstacles. After the angle is rotated, the staff can tighten the thread of the sealing locking mechanism 2, so that the thread of the sealing locking mechanism 2 can advance into the turning seam between the first ring sleeve 102 and the second ring sleeve 108 to perform a top-contact seal. At the same time, the top teeth 205 behind the sealing locking mechanism 2 will also touch the surface of the first ring sleeve 102 and the second ring sleeve 108, so that the first power pipe 1 and the second power pipe 101 can be rotated and locked, and it can ensure that the connection between the two power pipes does not loosen during use, provide a reliable physical connection, enhance the stability of the overall structure, and while locking, it can also effectively prevent gaps between the pipes caused by rotation or other external forces, thereby reducing the risk of leakage and ensuring the safety of internal cables and the normal operation of the power system.

[0030] like Figure 4 As shown, the sealing locking mechanism 2 includes a sealing disk 201, and a threaded column 204 is fixedly installed on the lower surface of the sealing disk 201.

[0032] A sealing ring 203 is fixedly installed on the lower surface of the sealing disk 201. The sealing ring 203 can be threadedly advanced into the semi-arc groove 103 between the first ring sleeve 102 and the second ring sleeve 108 through the threaded column 204, thereby achieving a top-touching seal at the transition seam between the first ring sleeve 102 and the second ring sleeve 108.

[0033] Two circles of top teeth 205 are fixedly installed on the lower surface of the sealing disk 201. The two groups of top teeth 205 are located on the outer and inner sides of the sealing ring 203, so that the two circles of top teeth 205 can be pressed against the upper surfaces of the first ring sleeve 102 and the second ring sleeve 108 through the threaded column 204, thereby applying a rotational locking force to the first ring sleeve 102 and the second ring sleeve 108.

[0034] Through the design of the sealing disk 201, the handle 202, the sealing ring 203, the threaded column 204 and the top gear 205, after the rotation angle of the first power tube 1 and the second power tube 101 is adjusted, the staff can rotate the handle 202 on the upper surface of the sealing disk 201 to drive the threaded column 204 to be threadedly installed into the threaded hole of the second ring sleeve 108. In the process of the sealing disk 201 being screwed into the threaded hole through the threaded column 204, the sealing disk 201 can drive the sealing ring 203 on the lower surface to advance and touch the semi-arc groove 103 opened at the turning seam between the first ring sleeve 102 and the second ring sleeve 108, and through the sealing ring 203 The top pressure can effectively seal the connection, prevent the intrusion of moisture, soil and other pollutants, and protect the safety of the internal cables. After the sealing ring 203 is pressed into the semi-arc groove 103, the top teeth 205 on the outside and inside of the sealing ring 203 can be pressed on the surfaces of the first ring sleeve 102 and the second ring sleeve 108 respectively, thereby applying a rotational locking force to the first ring sleeve 102 and the second ring sleeve 108. During the tightening process, the top teeth 205 can effectively resist the loosening and rotation of the first power tube 1 and the second power tube 101 caused by external force or ground subsidence, ensuring long-term stability of the connection and improving the safety of the overall system.

[0035] According to the above technical solution, the working steps of this solution are summarized and sorted out: in the process of laying the MPP power pipe, if an obstacle is encountered and the MPP power pipe needs to be bent, the staff can turn the rotating mouth 106 of the first power pipe 1 to the direction in which the bending is required, and then the staff can push the second power pipe 101 to drive the second ring sleeve 108 to rotate in the first ring sleeve 102 of the first power pipe 1, and in the process of rotation, the second power pipe 101 will rotate in the rotating mouth 106 of the first ring sleeve 102, so that the opening angle of the rotating mouth 106 is the rotation angle of the first power pipe 1 and the second power pipe 101, and after the angle is rotated, the staff can rotate the handle 202 on the upper surface of the sealing disk 201 to drive the threaded column 204 to be threadedly installed in the threaded hole of the second ring sleeve 108, and the sealing disk 201 During the process of screwing the threaded column 204 into the threaded hole, the sealing disk 201 can drive the sealing ring 203 on the lower surface to advance and touch the semi-arc groove 103 opened at the turning seam between the first ring sleeve 102 and the second ring sleeve 108. The top pressure of the sealing ring 203 can effectively seal the connection to prevent the invasion of moisture, soil and other pollutants. After the sealing ring 203 is pressed into the semi-arc groove 103, the top teeth 205 on the outside and inside of the sealing ring 203 can be pressed on the surfaces of the first ring sleeve 102 and the second ring sleeve 108 respectively, thereby applying a rotational locking force to the first ring sleeve 102 and the second ring sleeve 108, which can effectively resist the loosening and rotation of the first power tube 1 and the second power tube 101 caused by external force or ground subsidence, ensure the long-term stability of the connection, and improve the safety of the overall system.

[0036] In summary: the first power pipe 1 and the second power pipe 101 can be rotated through the first ring sleeve 102 and the second ring sleeve 108, allowing the MPP power pipe to be flexibly bent when encountering obstacles, making it convenient for staff to adjust the direction of the pipeline according to actual conditions and avoid laying difficulties caused by obstacles.
