A glass reinforced plastic pipe

Abstract

This utility model discloses a fiberglass pipe, comprising two or more fiberglass pipes, with a sleeve disposed between the two fiberglass pipes. The outer walls at both ends of the fiberglass pipes are configured with inclined openings, and the inner walls at both ends of the sleeve are configured with inwardly inclined openings adapted to the inclined openings. This utility model achieves an interference fit by setting toothed rings on the inclined openings at both ends of the fiberglass pipes and setting rubber layers on the inwardly inclined openings at both ends of the sleeve, thereby pushing the front end of the fiberglass pipe into the sleeve by external force, ensuring a tight fit between the fiberglass pipe and the sleeve, and improving the sealing performance.

Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe technology, and in particular to fiberglass pipes. Background Technology

[0002] Currently, a large number of power transmission cables are buried underground, which requires fiberglass pipes to protect the cables.

[0003] In existing technologies, cables are placed inside fiberglass pipes. However, the lack of a sleeve connection between two fiberglass pipes can lead to problems such as insufficient sealing, inadequate structural strength, or reduced pressure resistance. For example, in the published document CN210510698U, the use of a threaded rod through two sets of connecting rings prevents the two sets of connecting pipes from coming loose. However, this does not solve the problem of insufficient sealing after the two fiberglass pipes are connected, which can cause rainwater and sewage to seep into the pipes. Long-term immersion of the cable may lead to line faults or short circuits.

[0004] Therefore, the applicant hereby submits this application. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a fiberglass pipe that achieves an interference fit through a toothed ring on the fiberglass pipe and a rubber layer inside the sleeve.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A fiberglass pipe includes two or more fiberglass pipes, with a sleeve provided between the two fiberglass pipes. Both ends of the fiberglass pipes are provided with inclined openings, and both ends of the sleeve are provided with inwardly inclined openings adapted to the inclined openings.

[0008] In the above scheme, preferably, the inclined opening is provided with multiple toothed rings, which are evenly distributed at intervals.

[0009] In the above scheme, preferably, the toothed ring can be circular or semi-circular.

[0010] In the above scheme, preferably, a rubber layer is provided on the inner inclined opening wall.

[0011] In the above scheme, preferably, the rubber layer is an elastic rubber layer.

[0012] In the above scheme, preferably, the toothed ring and the rubber layer are interference fit, each toothed ring has the same height, and the height of the rubber layer is adapted to the height of the toothed ring.

[0013] In the above scheme, preferably, the distance between the fiberglass pipe and the sleeve is the length of the inclined opening.

[0014] The beneficial effects of this utility model are: by setting toothed rings on the inclined openings at both ends of the fiberglass pipe and setting rubber layers on the inner inclined openings at both ends of the sleeve, the front end of the fiberglass pipe is pushed into the sleeve by external force to achieve an interference fit, ensuring a tight fit between the fiberglass pipe and the sleeve and improving the sealing performance.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0020] See Figures 1-4 A fiberglass pipe 1 includes two or more fiberglass pipes 1. The fiberglass pipe 1 can be used for cable protection. Since there will be gaps between two fiberglass pipes 1, resulting in poor sealing, insufficient sealing can easily lead to rainwater and sewage seeping into the pipe. Long-term immersion of the cable may cause line faults or short circuits. Inclined openings 3 are set at both ends of the fiberglass pipe 1 pair. A sleeve 2 is set between the two fiberglass pipes 1. The two ends of the sleeve 2 are set with inwardly inclined openings 4 that are adapted to the inclined openings 3. Setting the inclined openings 3 and the inwardly inclined openings 4 can improve the strength of the fit between the two.

[0021] Specifically, multiple toothed rings 5 ​​are fixedly installed on the inclined openings 3 at both ends of the fiberglass pipe 1. The toothed rings 5 ​​are evenly spaced and have the same height. A rubber layer 6 is installed on the inner inclined openings 4 at both ends of the sleeve 2. The rubber layer 6 is an elastic rubber layer, and the thickness of the rubber layer 6 is adapted to the height of the toothed rings 5. The thickness of the rubber layer 6 is greater than the height of the toothed rings 5.

[0022] To improve the sealing performance between the fiberglass pipe 1 and the sleeve 2, the toothed ring 5 and the rubber layer 6 are interference fit, which allows the two to fit together tightly. The rubber layer 6 can be used to fill the gap between the sleeve 2 and the fiberglass pipe 1, ensuring no leakage at the joint and improving the sealing performance. A well-sealed connection can reduce pipeline corrosion or structural damage caused by media leakage, and indirectly extend the service life of the overall pipeline system.

[0023] Furthermore, the elastic rubber layer adheres to the wall of the inner inclined opening 4 of the sleeve 2. Under the action of external force, the front inclined opening 3 of the fiberglass pipe 1 is pushed into the inner inclined opening 4 of the sleeve 2. Due to the buffering effect of the elastic rubber layer, the inclined opening 3 of the fiberglass pipe 1 is completely pushed into the inner inclined opening 4 of the sleeve 2. The toothed ring 5 can achieve a tight fit with the rubber layer 6, improving the sealing performance of the connection between the two. The good sealing performance between the fiberglass pipe 1 and the sleeve 2 can effectively isolate sewage, rainwater and mud, avoid the cable from being immersed in water for a long time or being chemically corroded, and ensure the safe operation of the line. The distance that the fiberglass pipe 1 is pushed into the sleeve 2 is the length of the inclined opening 3. The interference fit between the two improves the installation efficiency between the fiberglass pipe 1 and the sleeve 2.

[0024] In this embodiment, the toothed ring 5 can be semi-circular or circular, and can be designed according to actual needs. In order to further improve the tight fit between the fiberglass pipe 1 and the sleeve 2, a rubber ring that matches the toothed ring 5 can be set on the rubber layer 6. The two can fit tightly to achieve double sealing. In this embodiment, the sleeve 2 can also be adapted to the needs of different working scenarios.

[0025] Working principle: With the multiple toothed rings 5 ​​on the inclined openings 3 at both ends of the fiberglass pipe 1 and the elastic rubber layer on the inner inclined openings 4 at both ends of the sleeve 2, the fiberglass pipe 1 is pushed into the sleeve 2 under the action of external force. The inclined openings 3 at both ends of the fiberglass pipe 1 are pushed along the inner inclined openings 4 of the sleeve 2. When the inclined openings 3 of the fiberglass pipe 1 are completely inserted into the inner inclined openings 4 of the sleeve 2, the toothed rings 5 ​​on the inclined openings 3 are completely and tightly fitted with the elastic rubber layer on the inner inclined openings 4, which improves the sealing performance of the connection between the two fiberglass pipes 1 through the sleeve 2.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
