[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figures 1-4 As shown in the figure, this utility model provides a high-performance MPP power conduit, including a conduit body 1. The conduit body 1 includes an outer pipe 101, a heat insulation pipe 102, and an inner pipe 103. The outer pipe 101 and the inner pipe 103 surround a heat insulation cavity. The heat insulation pipe 102 is inserted into the heat insulation cavity. The heat insulation pipe 102 is made of asbestos pipe, and the inner pipe 103 is made of MPP material. The conduit made of MPP material is specifically a conduit made of modified polypropylene (MPP) material, which has strong pressure resistance and impact resistance. The outer pipe 101 is made of polyethylene pipe. The conduit body 1 is divided into an outer pipe 101, a heat insulation pipe 102, and an inner pipe 103. The overall heat insulation performance is strong and can isolate heat from the external environment. It is mainly used for laying outdoor circuit conduits. This can prevent the heat generated by sunlight from being transferred to the cables stored inside, and prevent the cables from overheating due to external heat. The conduit body 1 thus has strong heat insulation performance and pressure resistance.

[0028] It should be noted that the power pipeline is connected together by multiple pipeline bodies 1. In order to position the connected pipeline bodies 1, a positioning shell 2, an upper positioning clamp 4, and a lower positioning clamp 10 are provided on the outside of the pipeline body 1. The upper positioning clamp 4 and the lower positioning clamp 10 are located on the upper and lower sides of the pipeline body 1, respectively. The upper positioning clamp 4 is installed on the top of the positioning shell 2, and the lower positioning clamp 10 slides in conjunction with the storage slot inside the positioning shell 2.

[0029] Specifically, the positioning shell 2 is provided with a support frame 3 for supporting the positioning shell 2. The support frame 3 includes two vertical rods, a short rod, and a long rod. The two vertical rods are distributed in parallel on the support frame 3 and are connected by a short rod. The two short rods on both sides of the pipe body 1 are connected by a long rod.

[0030] To adjust the height of the lower positioning hoop 10, a height adjustment rod 5, a thick gear 6, a thin gear 7, and a power mechanism 8 are provided on the positioning shell 2. The height adjustment rod 5 is rotatably connected to the upper positioning hoop 4. The height adjustment rod 5 is provided with a first threaded part. The thick gear 6 is provided with a second threaded part that mates with the first threaded part on the height adjustment rod 5. The thick gear 6 and the thin gear 7 are connected by gear meshing. The thick gear 6 is located on the upper side of the upper positioning hoop 4 and is rotatably connected to the upper positioning hoop 4. The thickness of the thick gear 6 is greater than the distance the lower positioning hoop 10 moves. The thin gear 7 is connected to the power mechanism 8, which is used to drive the thin gear 7 to rotate. The power mechanism 8 is mounted on the positioning shell 2.

[0031] It should be noted that this can be referred to Figure 2 The power mechanism 8 includes a sprocket, a chain, a transmission housing, and a power motor. The output end of the power motor is equipped with a sprocket, which can be connected to the output end of the power motor via a common key or keyway. A transmission shaft is inserted into the transmission housing and inserted into a thin gear 7. A sprocket is sleeved on the outside of the transmission shaft. The sprocket and the transmission shaft can also be connected by a key or keyway. The two sprockets are connected by a chain. The power mechanism 8 is equipped with an auxiliary frame 12. There are two auxiliary frames 12, and both auxiliary frames 12 are mounted on the L-frame 9.

[0032] In order to support the power mechanism 8, an L-frame 9 is provided on the positioning shell 2, and the power mechanism 8 is mounted on the L-frame 9.

[0033] It should be noted that the height adjustment rod 5 is provided with an end plate and a pressure ring 11 at the bottom. The end plate is installed at the bottom end of the height adjustment rod 5, and the lower positioning hoop 10 is located between the end plate and the pressure ring 11. The lower positioning hoop 10 is rotatably connected to the height adjustment rod 5, and the position of the height adjustment rod 5 corresponding to the lower positioning hoop 10 is set as a smooth straight rod structure.

[0034] When the power mechanism 8 is started, it drives the thin gear 7 to rotate. The thin gear 7 drives the thick gear 6 to rotate through gear meshing. The thick gear 6 is connected to the height adjustment rod 5 by a thread. The rotating thick gear 6 can drive the height adjustment rod 5 to move down. The end plate and pressure ring 11 in the height adjustment rod 5 can drive the lower positioning clamp 10 to move, thereby clamping or releasing the pipe body 1, thus locking the position of the pipe body 1 and facilitating the subsequent installation of the pipe body 1.

[0035] It should be noted that the positioning shell 2, support frame 3, height adjustment rod 5, thick gear 6, thin gear 7, and power mechanism 8 are part of the positioning mechanism. There are two positioning mechanisms, and the two positioning mechanisms are respectively located on both sides of the pipe body 1. In this way, the two positioning mechanisms on the left and right work simultaneously, which can drive the lower positioning clamp 10 to move vertically up and down. This requires the two power mechanisms 8 on the left and right to be started simultaneously. Specifically, the two power motors in the two power mechanisms 8 can be connected in series on the same circuit.

[0036] In another embodiment, two positioning shells 2 are provided, respectively located on both sides of the pipe body 1. A positioning rod with a smooth outer surface is installed inside the positioning shell 2 on the side away from the power mechanism 8, and the positioning rod slides into the lower positioning clamp 10. By eliminating the need for two power mechanisms 8 and using a smooth, unpowered positioning rod to guide the movement of the lower positioning clamp 10, the cost is reduced, but the lifting force on the lower positioning clamp 10 is correspondingly lower.

[0037] In summary, this utility model embodiment provides a high-performance MPP power pipeline. The starting power mechanism 8 drives the thin gear 7 to rotate, which in turn drives the thick gear 6 to rotate via gear meshing. The thick gear 6 is threadedly connected to the height adjustment rod 5. The rotating thick gear 6 causes the height adjustment rod 5 to move downwards. The end plate and pressure ring 11 in the height adjustment rod 5 cause the lower positioning clamp 10 to move, thereby clamping or releasing the pipeline body 1, thus locking the position of the pipeline body 1 and facilitating subsequent installation of the pipeline body 1.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
