[0002] MPP pipe is also called MPP power cable protection pipe, which is divided into excavation type and non-excavation type. MPP non-excavation pipe is also called MPP top pipe or drag pipe. MPP pipe uses modified polypropylene as the main raw material, which has the characteristics of high temperature resistance and external pressure resistance. It is suitable for medium and low voltage transmission line cable pipes below 10KV. Usually, when placing multiple power pipe bodies, it is necessary to first connect them horizontally, and then place them in the prefabricated pit for longitudinal connection;

[0003] In the prior art, the Chinese patent publication number CN114977044A discloses a high-stability MPP power pipe connection structure, a connection frame and an installation method thereof. Through the clamping-type MPP pipe connection structure and the connection frame adapted thereto, the laying difficulty of the MPP power pipe is effectively reduced, the laying work intensity is reduced, and the laying efficiency of the MPP power pipe is improved;

[0004] However, when the patent connects multiple pipe bodies horizontally, the horizontal pipe bodies are only connected by simple horizontal blocks and slots. This method can only limit the horizontal positions of the two pipe bodies, but not the vertical positions. As a result, when the workers are performing vertical installation, the blocks at the horizontal positions of the two pipe bodies are prone to misalignment or falling off. Based on this, we propose an MPP power pipe connection structure. Utility Model Content

[0024] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 - Figure 5 As shown, an MPP power pipe connection structure includes a plurality of pipe bodies 1, and the same connecting sleeve 2 is sleeved on opposite sides of adjacent pipe bodies 1, and two supporting frames 3 are fixedly connected to the outer walls of the pipe bodies 1 in sequence;

[0026] A first mounting groove 4 is provided on one side and the bottom of the support frame 3, a second mounting groove 6 is provided on the other side and the top of the support frame 3, an embedding block 5 is symmetrically fixedly connected to the outer side of the second mounting groove 6 on one side and the top of the support frame 3, a T-shaped block 7 is rotatably connected to the inner wall of the second mounting groove 6, and a positioning rod 8 is fixedly connected to one side of the T-shaped block 7;

[0027] A clamping groove 14 connected to the first installation groove 4 is formed on one side and the bottom of the support frame 3 . A connecting tube 15 is rotatably connected to the inner wall of the first installation groove 4 . The connecting tube 15 is formed with a T-shaped hole 16 .

[0028] Furthermore, a guide hole 18 is provided at the top end of the second mounting groove 6, a connecting groove 17 is provided at the top end of the guide hole 18, a spring 9 is fixedly connected to the top end of the connecting groove 17, a movable plate 10 is fixedly connected to the bottom end of the spring 9, a positioning tube 11 which passes through the guide hole 18 is fixedly connected to the bottom end of the movable plate 10, a movable hole 12 which is connected to the connecting groove 17 is provided on one side of the support frame 3, a connecting rod 13 which passes through the movable hole 12 is fixedly connected to the outer wall of the movable plate 10, and the positioning rod 8 is rotated upward so that the positioning rod 8 drives the T-block 7 to rotate ninety degrees, thereby the T-block 7 drives the connecting tube 15 to rotate ninety degrees, and the positioning rod 8 is rotated to the bottom of the positioning tube 11, so that the subsequent positioning tube 11 can limit the position of the positioning rod 8.

[0029] Furthermore, the width of adjacent embedded blocks 5 is the same as the width inside the snap-in groove 14, and the sizes and shapes of multiple support frames 3 are exactly the same. When multiple tube bodies 1 are transversely connected, two tube bodies 1 are pulled so that the support frames 3 on the outer walls of the two tube bodies 1 are close to each other, and then the embedded block 5 on one side of the support frame 3 is slid into the snap-in groove 14 on the other side of the support frame 3, thereby completing the transverse pull connection of multiple tube bodies 1.

[0030] Furthermore, the outer wall of the T-block 7 is adapted to the inside of the T-hole 16, and the inner wall of the connecting sleeve 2 is in close contact with the outer walls of the two tube bodies 1, so that when the embedded block 5 located below passes through the inside of the first mounting groove 4, a support frame 3 drives the T-block 7 on one side to slide into the inside of the T-hole 16 on one side of the connecting tube 15 until the bottom surfaces of the two support frames 3 are located in the same horizontal plane, thereby limiting the longitudinal positions of the two tube bodies 1.

[0031] Furthermore, the interior of the positioning cylinder 11 is adapted to the outer wall of the positioning rod 8, and the diameter of the guide hole 18 is the same as the diameter of the positioning cylinder 11, so that when the positioning cylinder 11 moves downward due to the reaction force of the spring 9, the interior of the positioning cylinder 11 can be sleeved on the top of the positioning rod 8, thereby limiting the position of the positioning rod 8.

[0032] Furthermore, the outer wall of the connecting rod 13 contacts the inner wall of the moving hole 12 , and a pull rod is fixedly connected to one end of the connecting rod 13 , so that when the connecting rod 13 is pulled by the pull rod to move, the connecting rod 13 can only move up and down along the inner wall of the moving hole 12 .

[0033] Working principle: First, when connecting multiple tube bodies 1 horizontally, pull two tube bodies 1 so that the support frames 3 on the outer walls of the two tube bodies 1 are close to each other, and then slide the embedding block 5 on one side of one support frame 3 into the clamping groove 14 on the side of the other support frame 3. When the embedding block 5 located below passes through the first installation groove 4, one support frame 3 drives the T-block 7 on one side to slide into the T-hole 16 on the side of the connecting tube 15 until the bottom surfaces of the two support frames 3 are located in the same horizontal plane, thereby limiting the longitudinal positions of the two tube bodies 1. Then, pull the pull rod upward so that the pull rod drives the connecting rod 13 to move, and the moving rod drives the movable plate 10 to move, and then the movable plate 10 drives the spring 9 to compress while driving the positioning tube 11 to move upward to the inside of the guide hole 18;

[0034] Secondly, rotate the positioning rod 8 upward so that the positioning rod 8 drives the T-block 7 to rotate ninety degrees, thereby the T-block 7 drives the connecting tube 15 to rotate ninety degrees, and the positioning rod 8 rotates to the bottom of the positioning tube 11, release the pull rod, and due to the reaction force of the spring 9, the movable plate 10 drives the positioning tube 11 to move downward until the positioning tube 11 is sleeved on the outer wall of the positioning rod 8, thereby limiting the rotation angle of the T-block 7 and the connecting tube 15, and then limiting the lateral direction of the two tube bodies 1, thereby completing the connection between adjacent support frames 3 and limiting the lateral and longitudinal directions of the tube body 1, ensuring the stability of multiple tube bodies 1 when placed, and no external cable is required to limit the entire tube body 1 when placed, and then the opposite sides of the two tube bodies 1 are sleeved inside a connecting sleeve 2 to complete the longitudinal connection of multiple tube bodies 1.

[0035] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
