Description

Technical Field

[0001] This invention relates to the field of power pipeline technology, specifically high-density polyethylene power pipelines. Background Technology

[0002] Power pipelines are basic electrical equipment. Wires and cables are bundled together and placed in power pipelines, either buried underground or in buildings.

[0003] Chinese utility model patent with authorization number "CN205791305U" discloses a "high-density polyethylene power pipe". The application addresses the problem that existing power pipes suffer severe corrosion on the outside after long-term contact with rainwater or sewage, which seriously threatens the cables inside and affects their service life. By providing an anti-corrosion material layer on the pipe surface and a flame-retardant sleeve inside the outer pipe, the corrosion resistance is improved, indirectly extending the service life and solving the problems existing in the prior art.

[0004] In practical applications, to address the problems of existing technologies, a sandwiched groove can be opened inside the power pipeline, and a protective component with internal foam filling can be installed in the sandwich. When rainwater or sewage corrodes the pipeline to the point where gas can enter the pipeline, the foam filling comes into contact with the gas, causing the foam filling to expand and fill various parts of the pipeline. This not only completes a simple repair of the corroded pipeline, but also further prevents gas, rainwater, and sewage from re-entering, indirectly extending the service life of the pipeline. Therefore, the applicant proposes a new device based on this improvement to solve the problems existing in the prior art. Summary of the Invention

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0028] Power conduits are fundamental electrical equipment. Electrical wires and cables are bundled together and placed within these conduits, buried underground or within buildings. Existing power conduits, after prolonged exposure to rainwater or sewage, suffer severe corrosion on their exterior, seriously threatening the cables inside and affecting their lifespan. Therefore, the applicant proposes a novel device to address the problems existing in the prior art. (Reference...) Figures 1-5 It is known that the device includes a connecting component 2, wherein the connecting component 2 includes a connecting pipe head 201, and an assembly component 1 is installed between the two connecting pipe heads 201. A rotatable protective component 3 is inserted inside the assembly component 1, and one end of the protective component 3 is fixed to one of the connecting pipe heads 201.

[0029] Among them, reference Figure 3 As can be seen, in this application, the assembly component 1 includes an assembly half-pipe 101. There are two assembly half-pipes 101. The interior of each assembly half-pipe 101 is provided with an assembly groove 103. The top of one assembly half-pipe 101 is provided with positioning grooves 102 on both sides. The bottom of the other assembly half-pipe 101 is fixedly connected with positioning pins 105 on both sides. The positioning pins 105 and the positioning grooves 102 are compatible.

[0030] In addition, refer to Figure 5 As can be seen, in this application, the protective component 3 includes a connecting sleeve 301. One end of the connecting sleeve 301 is fixed to the inside of one of the connecting pipe heads 201. The other end of the connecting sleeve 301 is fixedly connected to a columnar mounting bracket 304. The mounting bracket 304 is installed in two assembled half-pipe bodies 101 through the assembly groove 103. Several holding trays 302 are fixedly connected to the outside of the mounting bracket 304. The inside of the holding trays 302 is filled with foaming filler 303. It should be noted that in actual use, by opening a sandwich groove inside the power pipeline and installing the protective component 3 with foaming filler 303 inside the sandwich, when rainwater or sewage corrodes the pipeline to the point that gas can enter the pipeline, the foaming filler 303 comes into contact with the gas, thereby causing the foaming filler to expand and fill various positions inside the pipeline. This not only completes a simple repair of the corroded pipeline, but also further prevents gas, rainwater and sewage from entering again, indirectly extending the service life of the pipeline.

[0031] In addition, refer to Figure 3As can be seen, in this application, the two ends of the assembled half-pipe 101 are respectively fixedly connected with assembly threads 104, and the inner wall of the connecting pipe head 201 is provided with a threaded groove, which is compatible with the assembly threads 104. It should be added that in this application, the middle part of the assembled half-pipe 101 is also coated with an anti-corrosion material. The anti-corrosion material is one of folded epoxy anti-corrosion coating, grease coating or folded modified raw lacquer latex paint. The anti-corrosion material reduces the corrosion of the pipe by rainwater or sewage. It should be emphasized that the improvement proposed in this application is a secondary protection of the pipe based on the anti-corrosion material.

[0032] It should be added that, for reference Figure 4 As can be seen, in this application, a connecting ring 203 is fixedly connected to one end of the connecting pipe head 201, and a reinforcing bolt 205 is inserted and installed on the edge of the connecting ring 203. There are several reinforcing bolts 205, which are evenly distributed at equal angles on the edge of the connecting ring 203. A hand-held notch 202 is provided between every two adjacent reinforcing bolts 205. The hand-held notch 202 serves to enable the connecting pipe head 201 to be screwed and fastened to the outside of the two assembled half-pipe bodies 101 during actual installation.

[0033] It should also be noted that in this application, the two ends of the top of one side of the connecting ring 203 are respectively provided with a fixed connecting pin 204 and a connecting groove 206, wherein the connecting pin 204 and the connecting groove 206 are adapted to each other, and the connecting pin 204 and the connecting groove 206 play a role in enhancing the stability after connection. It should be added that in this application, the radius of the connecting tube head 201 is smaller than the radius of the connecting ring 203, and one end of the connecting sleeve 301 passes through the connecting tube head 201 and is fixed to one side of the connecting ring 203.

[0034] Furthermore, it should be added that in this application, the edge of the connecting ring 203 is provided with a number of connecting holes, which are evenly distributed at equal angles along the edge of the connecting ring 203. The connecting holes are compatible with the reinforcing bolts 205, and a limit nut can be installed on the outside of the reinforcing bolts 205. It should be emphasized that, through the setting of the connecting ring 203 and the reinforcing bolts 205 on the connecting ring 203, this application enables the installation and fixing of multiple pipes to be completed through the reinforcing bolts 205 and the connecting ring 203 during actual use.

[0035] In actual use, the positioning grooves 102 and positioning pins 105 on the two assembled half-pipes 101 are aligned, and the two assembled half-pipes 101 are connected together by applying pressure. At this time, the connecting ring 203 is held and the mounting bracket 304 connected to the connecting ring 203 is inserted into the assembly groove 103 between the two assembled half-pipes 101. After the mounting bracket 304 is inserted into the two assembled half-pipes 101, the connecting pipe head 201 is fastened to the outside of the two assembled half-pipes 101 by rotating the connecting ring 203. At this time, the assembly of a single unit of the device is completed. When multiple units need to be assembled, the connecting pins 204 and connecting grooves 206 on the connecting ring 203 are aligned, and the reinforcing nuts installed on the reinforcing bolts 205 are rotated to achieve the installation of multiple pipes.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
