[0025] Example:

[0026] As attached Figure 1 To Attachment Figure 5 As shown:

[0027] The utility model provides a CPVC high-voltage electric power pipe, comprising an electric power pipe body 1, a first annular mounting seat 2 is installed at one end of the circumference of the electric power pipe body 1, a first annular slide groove 3 is penetrated through one side of the first annular mounting seat 2, a pair of semi-annular baffles 4 are slidably installed in the first annular slide groove 3, and both ends of the pair of semi-annular baffles 4 extend to the outside of the first annular slide groove 3, a first annular mounting plate 5 is installed at one end of the circumference of the first annular mounting seat 2, a second annular mounting plate 6 is installed on one side of the first annular mounting plate 5 by bolts, and the second annular mounting plate 6 is slidably connected to the circumference of the electric power pipe body 1, a second annular mounting seat 7 is installed at the other end of the circumference of the electric power pipe body 1, and the second annular mounting seat 7 is provided with a second annular slide groove 8 on a side away from the first annular mounting seat 2, a heat-resistant layer 9 is provided inside the electric power pipe body 1, and a waterproof layer 10 is provided on the surface of the electric power pipe body 1.

[0028] Among them, a pair of semi-annular baffles 4 are symmetrically arranged.

[0029] Among them, the size of the second annular groove 8 matches the size of a pair of semi-annular baffles 4, so that the pair of semi-annular baffles 4 can enter the second annular groove 8, which is convenient for quickly aligning and splicing the two power tube bodies 1 together, and after welding is completed, the welding position of the two power tube bodies 1 can be protected to prevent debris from falling on the welding place when the welding place is not completely cooled and affecting the welding effect.

[0030] Among them, a pull plate 11 is installed on one side of a pair of semi-annular baffles 4. When welding between two power pipe bodies 1, the staff can pull the pull plate 11 according to the welding position, so that the semi-annular baffle 4 slides along the first annular groove 3, so that the position to be welded is exposed, which is convenient for the staff to perform welding.

[0031] Among them, a reinforcing rib 12 is provided inside the power tube body 1 to improve the strength of the power tube body 1 and extend the service life of the power tube body 1.

[0032] Among them, the material of the heat-resistant layer 9 is polyimide. Polyimide has excellent high-temperature stability and can still maintain good physical and chemical properties in high-temperature environments, which makes it very suitable for use as the heat-resistant layer 9 material of high-temperature pipelines. At the same time, polyimide has good chemical corrosion resistance and can resist the erosion of many chemical substances, including acids, alkalis, etc., so it can also maintain the stability of the pipeline in a chemical environment.

[0033] Among them, the material of the waterproof layer 10 is polyethylene. Polyethylene has good waterproof properties and can effectively prevent moisture from penetrating into the inside of the pipeline, protecting the pipeline from moisture erosion and leakage. At the same time, polyethylene has good corrosion resistance and can resist erosion by many chemicals, including chemicals in water and salts in soil, thereby extending the service life of the pipeline.

[0034] The working principle of this embodiment is as follows: when welding two power tube bodies 1, the staff first aligns the two power tube bodies 1 so that the pair of semi-annular baffles 4 at one end of the first power tube body 1 are aligned with the position of the second annular slide groove 8 at one end of the second power tube body 1. After the alignment is completed, the pair of semi-annular baffles 4 are inserted into the second annular slide groove 8 to achieve preliminary splicing, and then the bolts on the second annular mounting plate 6 are removed. At this time, the second annular mounting plate 6 can slide on the circumferential side of the power tube body 1. After the staff slides the second annular mounting plate 6 to a position away from the first annular mounting plate 5, the pair of semi-annular baffles 4 are pulled to expose the connection position of the two power tube bodies 1 and weld them. The staff can pull the pair of semi-annular baffles 4 in turn for welding in turn to improve the stability of the two power tube bodies 1 during welding. After the welding is completed, the pair of semi-annular baffles 4 are pushed back into the second annular slide groove 8 to achieve blocking and protection of the welding position, and then the second annular mounting plate 6 is slid. , after the second annular mounting plate 6 is brought close to the position of the first annular mounting plate 5, the first annular mounting plate 5 and the second annular mounting plate 6 are fixed together by bolts, wherein the reinforcing ribs 12 can improve the strength of the power pipe body 1 and extend the service life of the power pipe body 1. The heat-resistant layer 9 is made of polyimide, which has excellent high-temperature stability and can still maintain good physical and chemical properties under high temperature environments, which makes it very suitable for use as the heat-resistant layer 9 material of high-temperature pipelines. At the same time, polyimide has good chemical corrosion resistance and can resist the erosion of many chemical substances, including acids, alkalis, etc., and can also maintain the stability of the pipeline in a chemical environment. The waterproof layer 10 is made of polyethylene, which has good waterproof properties and can effectively prevent moisture from penetrating into the interior of the pipeline, protecting the pipeline from moisture erosion and leakage. At the same time, polyethylene has good corrosion resistance and can resist the erosion of many chemical substances, including chemicals in water and salts in soil, thereby extending the service life of the pipeline.
