Description

Technical Field

[0001] This utility model belongs to the field of PVC power pipe technology, and more specifically, it relates to an aging-resistant PVC power pipe. Background Technology

[0002] PVC power pipe (polyvinyl chloride power pipe) is a type of pipe mainly used for laying cables in power engineering. It is usually used to protect cables from the influence of the external environment, such as mechanical damage, moisture, chemical corrosion, etc. It is made of polyvinyl chloride (PVC) material and has good insulation, corrosion resistance, aging resistance and high strength.

[0003] Nowadays, some PVC power pipes are often connected using a socket joint. However, during installation, the socket joint is relatively fragile and can easily become loose due to dragging. Moreover, when filling the tunnel with soil or concrete after installation, the external pressure is concentrated on the connection, which can also easily cause loosening.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an aging-resistant PVC 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 an aging-resistant PVC power pipe, which is achieved by the following specific technical means:

[0006] An aging-resistant PVC power pipe includes a multi-layer composite pipe body, which comprises, from the inside out, a PVC base layer, a weather-resistant modified layer, and an outer protective layer. A connecting sleeve is installed at one end of the multi-layer composite pipe body. An installation ring is installed on the periphery of the end of the multi-layer composite pipe body near the connecting sleeve. A pair of installation blocks are installed on the periphery of the installation ring. A through groove is provided on one side of the installation block. An installation ring is installed on the periphery of the end of the multi-layer composite pipe body away from the connecting sleeve. A pair of installation blocks are installed on both sides of the installation ring. A through groove is provided on one side of the installation block. The pipe also includes an arc-shaped baffle and a locking mechanism.

[0007] Furthermore, the weather-resistant modified layer is made of PVC resin.

[0008] Furthermore, the outer protective layer is made of high-density polyethylene.

[0009] Furthermore, the dimensions of the connecting sleeve match the dimensions of the end of the multi-layer composite tube near the second mounting ring.

[0010] Furthermore, the locking mechanism includes a locking bolt, a limiting block, and a nut. One end of the locking bolt is connected to one side of the limiting block. The thread on the surface of the locking bolt matches the thread on the inner ring of the nut. The locking bolt matches the dimensions of through slot one and through slot two.

[0011] Furthermore, a limiting groove is provided on one side of the through groove, and the size of the limiting groove matches the size of the limiting block.

[0012] Furthermore, a pair of connecting grooves are provided on both sides of the first mounting ring, and a pair of connecting grooves are provided on both sides of the second mounting ring at positions corresponding to the pair of connecting grooves.

[0013] Furthermore, a connecting block is installed on one side of the arc-shaped baffle. The dimensions of the connecting block match those of the first connecting groove and the second connecting groove, and the connecting block is interference-fitted with the first connecting groove and the second connecting groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The PVC power pipe is made of PVC resin and high-density polyethylene through a weather-resistant modified layer and an outer protective layer. This improves the aging resistance of the PVC power pipe.

[0016] By using the combined installation blocks 1, through slot 1, installation block 2, through slot 2, connecting slot 1, connecting slot 2, connecting block, and arc-shaped baffle, after the two adjacent multi-layer composite pipes are connected, one end of a pair of locking bolts is passed through the corresponding positions of through slot 1 and through slot 2, causing the limiting block to move into the limiting slot. Then, a nut is placed around the locking bolt and tightened, which further reinforces the connection between the two adjacent multi-layer composite pipes. Then, the connecting block on one side of the arc-shaped baffle is inserted into the corresponding positions of connecting slot 1 and connecting slot 2. Then, the position of the multi-layer composite pipe is adjusted so that the pair of arc-shaped baffles are distributed vertically, which can effectively bear the pressure brought by the backfilling of soil or concrete and prevent the connection of the multi-layer composite pipes from becoming loose.
