Description

Technical Field

[0001] This utility model belongs to the field of CPVC high-voltage power pipe technology, and more specifically, it relates to a CPVC high-voltage power pipe. Background Technology

[0002] CPVC high-voltage power pipe is a type of pipe used to protect power cables. Its inner diameter is related to the voltage level and usually needs to be greater than 150% of the cable's outer diameter. The higher the voltage level, the larger the inner diameter is required. It is mainly used in cable laying scenarios in power engineering and can adapt to different terrain and environmental requirements.

[0003] Currently, when some CPVC high-voltage power pipes are stored on construction sites, rainwater mixed with mud can easily flow into the pipes during rainy weather, causing sludge to accumulate inside. This will affect the inner wall surface of the pipes, especially during cable laying, potentially increasing cable friction, damaging the outer protective structure of the cable, and even interfering with cable performance. When the power pipes are not yet laid and encounter rainy weather, rainwater can easily flow into the pipes from the openings, forming water accumulation. This situation can easily cause corrosion of the inner wall of the power pipes and the surface of the wires, leading to damage and shortening the service life of the power pipes and wires.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a CPVC high-voltage power pipe in order to achieve a more practical value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a CPVC high-voltage power pipe, which is achieved by the following specific technical means:

[0006] A CPVC high-voltage power pipe includes a power pipe body with a socket and a spigot at both ends, and a sealing head. One side of the sealing head has a groove, and the periphery of the groove has several through grooves. A lead screw is rotatably connected to one side of the groove, and an mounting block is threadedly connected to the outer periphery of the lead screw. The periphery of the mounting block has several mounting grooves, and a transmission block is rotatably connected to each mounting groove via a shaft. The other end of the transmission block is rotatably connected to a fixing block via a shaft. The number of fixing blocks is equal to the number of through grooves, and one end of each fixing block matches the size of a through groove. A stop block is installed on the side of the sealing head near the groove.

[0007] Furthermore, the outer surface of the power pipe body is provided with a corrosion-resistant layer.

[0008] Furthermore, a fireproof layer is provided on the inner surface of the main body of the power pipe.

[0009] Furthermore, a limiting block is installed on the inner wall of the groove near one side of each through slot, and one end of the fixing block passes through the limiting block and is movably connected to the limiting block.

[0010] Furthermore, an adjusting block is installed at one end of the lead screw, which passes through one side of the stop block, and the surface of the adjusting block is provided with anti-slip texture.

[0011] Furthermore, a handle is installed on one side of the stop.

[0012] Furthermore, one end surface of the fixing block is provided with an anti-slip texture.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By using the sealing head, adjusting block, screw rod, mounting block, transmission block, and fixing block in combination, the operator inserts the sealing head of the corresponding size into the socket and spigot respectively. Then, the adjusting block is rotated, which drives the screw rod to rotate. The screw rod, through rotation, moves the mounting block to one side of the groove. During the movement of the mounting block, the transmission block drives one end of the fixing block to move out of the groove and abut against the inner wall of the socket and spigot, fixing the sealing head in the socket and spigot so that it is not easy to loosen. The sealing head can be removed by reversing the operation. This achieves the effect of quick installation and removal of the sealing head. At the same time, the sealing head inserted into the socket and spigot can effectively prevent rainwater and mud from entering the main body of the power pipe, so as to avoid affecting the normal use of the main body of the power pipe.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides a CPVC high-voltage power pipe, including a power pipe body 1. The two ends of the power pipe body 1 are respectively provided with a socket 101 and a spigot 102, the sizes of which are matched. It also includes a sealing head 2. It should be noted that the size of the sealing head 2 is designed according to the sizes of the socket 101 and spigot 102 of the power pipe body 1. Generally, the sizes of the socket 101 and spigot 102 of the power pipe body 1 are not the same, so a pair of sealing heads 2 are designed according to the power pipe body 1, and they match the sizes of the socket 101 and spigot 102 of the power pipe body 1. A groove 201 is provided on one side of the sealing head 2, and the periphery of the groove 201 is provided with… There are several through grooves 202. A lead screw 3 is rotatably connected to one side of the groove 201. It should be noted that the lead screw 3 has a self-locking function. During the transportation of the power pipe body 1, the lead screw 3 will not rotate due to the shaking of the vehicle. The outer periphery of the lead screw 3 is threadedly connected to an installation block 301. Several installation grooves 302 are provided on the periphery of the installation block 301. A transmission block 303 is rotatably connected to the installation groove 302 through a shaft. The other end of the transmission block 303 is rotatably connected to a fixing block 304 through a shaft. The number of fixing blocks 304 is equal to that of the through grooves 202. One end of the fixing block 304 matches the size of the through groove 202. A stop block 4 is installed on the side of the sealing head 2 near the groove 201.

[0028] The outer surface of the main body 1 of the power pipe is provided with a corrosion-resistant layer 103, which can be made of a modified epoxy resin coating.

[0029] Among them, the inner surface of the main body 1 of the power pipe is provided with a fireproof layer 104, and the material of the fireproof layer 104 can be a ceramicized silicone rubber composite layer.

[0030] In this design, a limiting block 203 is installed on the inner wall of the groove 201 near the side of each through groove 202. One end of the fixing block 304 passes through the limiting block 203 and is movably connected to the limiting block 203. The limiting block 203 can limit the movement of the fixing block 304.

[0031] One end of the lead screw 3 passes through one side of the stop block 4 and is equipped with an adjusting block 305. The surface of the adjusting block 305 is provided with anti-slip texture.

[0032] The block 4 has a handle 401 installed on one side, which makes it easy to insert the sealing head 2 into the socket 101 and the insertion port 102, and also makes it easy to pull out the sealing head 2.

[0033] The surface of one end of the fixing block 304 is provided with anti-slip texture. The anti-slip texture can increase the friction of the surface of the fixing block 304, so that the fixing block 304 can fix the sealing head 2 in the socket 101 and the insertion port 102.
