Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion MPP power pipe technology, specifically an anti-corrosion MPP power pipe. Background Technology

[0002] MPP power pipes are mainly used for laying cables, providing protection and support to ensure the safe operation of cables in various environments.

[0003] For example, a corrosion-resistant and flame-retardant MPP power pipe with authorization announcement number "CN221885958U" has a first and second reinforcing plate arranged alternately. By setting a flame-retardant reinforcing layer between the inner tubes and setting an anti-corrosion layer on the outer surface of the outer tube, the flame-retardant and anti-corrosion performance of the pipe is improved. Due to the rigid support structure on the elastic flame-retardant body of the flame-retardant reinforcing layer, it plays a role in strengthening the support and improving the overall strength of the pipe. However, in the use of MPP power pipes, multiple MPP power pipes need to be connected to achieve the protection of long cables. When connecting MPP power pipes, they rely on a large loop inside a small loop for insertion. This type of connection has no fixed structure, which may cause the connected MPP power pipes to separate, resulting in insufficient stability of the MPP power pipe connection and reducing the protective effect of the MPP power pipe. Utility Model Content

[0004] The purpose of this invention is to solve the problem of insufficient connection stability of MPP power pipes, which reduces the protective effect of MPP power pipes, and to propose an anti-corrosion MPP power pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a corrosion-resistant MPP power pipe, including a collar, a fixing structure connected to the outer wall of the collar, a protective structure connected to the rear of the inner wall of the collar, an insulating layer connected to the inner wall of the protective structure, and a groove plate connected to the right side of the fixing structure.

[0007] Preferably, the fixing structure includes a base and bolts. The inner wall of the base is fixedly connected to the lower part of the outer wall of the collar. The top left and right sides of the base are respectively threaded to the outer walls of two bolts. The outer walls of the bolts are threaded with arc plates.

[0008] Preferably, the inner wall of the arc plate fits against the outer wall of the collar.

[0009] Preferably, the right side of the base is fixedly connected to the left side of the groove plate.

[0010] Preferably, the protective structure includes an anti-corrosion layer and a thickening layer. The front of the outer wall of the anti-corrosion layer is fixedly connected to the rear of the inner wall of the collar. The inner wall of the anti-corrosion layer is fixedly connected to the outer wall of the thickening layer. An inner layer is fixedly connected to the inner wall of the thickening layer.

[0011] Preferably, the inner wall of the inner layer is fixedly connected to the outer wall of the insulating layer.

[0012] The present invention proposes a corrosion-resistant MPP power pipe with the following advantages: The inner wall of the arc plate in the fixing structure is fitted to the top of the outer wall of the collar. Bolts are then threaded onto the left and right sides of the top of the arc plate. Note that the bolts on both sides should not be tightened individually; after rotating the left bolt two turns, rotate the right bolt two turns to ensure consistent bolt descent and prevent misalignment or jamming. Continue until the outer wall of the bolt is fully inserted into the top circular opening of the base. At this point, the base, in conjunction with the arc plate, clamps the collar, preventing the inserted power pipe from detaching. This improves the connection strength at the collar, enhances the stability of the MPP power pipe connection, and improves the protective effect of the MPP power pipe. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] Please see Figure 1-4 In this embodiment, a corrosion-resistant MPP power pipe includes a collar 1, a fixing structure 2 connected to the outer wall of the collar 1, the collar 1 being modified polypropylene, a protective structure 3 connected to the rear of the inner wall of the collar 1, an insulating layer 4 connected to the inner wall of the protective structure 3, the insulating layer 4 being made of polyimide film, and a groove plate 5 connected to the right side of the fixing structure 2.

[0021] The fixing structure 2 includes a base 201 and bolts 202. The inner wall of the base 201 is fixedly connected to the lower part of the outer wall of the collar 1. The top left and right sides of the base 201 are respectively threaded to the outer walls of two bolts 202. The outer walls of the bolts 202 are threadedly connected to an arc plate 203. The bolts 202 fix the arc plate 203 and the base 201, and can stably press the power pipe inside the collar 1. The inner wall of the arc plate 203 fits against the outer wall of the collar 1. The right side of the base 201 is fixedly connected to the left side of the groove plate 5.

[0022] The inner wall of the arc plate 203 in the fixed structure 2 is fitted with the top of the outer wall of the collar 1. Then, bolts 202 are threadedly connected to the top left and right sides of the arc plate 203. Note that the bolts 202 on both sides should not be turned individually. After rotating the left bolt 202 two turns, rotate the right bolt 202 two turns to ensure that the bolts 202 descend in a consistent manner to prevent misalignment and jamming. Continue until the outer wall of the bolt 202 is completely inserted into the top round opening of the base 201. At this time, the base 201 and the arc plate 203 clamp the collar 1 to prevent the plugged power pipe from coming off, which improves the connection strength at the collar 1, improves the docking stability of the MPP power pipe, and improves the protection effect of the MPP power pipe.

[0023] The protective structure 3 includes an anti-corrosion layer 301 and a thickened layer 302. The front of the outer wall of the anti-corrosion layer 301 is fixedly connected to the rear of the inner wall of the collar 1. The anti-corrosion layer 301 is made of modified polypropylene. The inner wall of the anti-corrosion layer 301 is fixedly connected to the outer wall of the thickened layer 302. An inner layer 303 is fixedly connected to the inner wall of the thickened layer 302. Both the thickened layer 302 and the inner layer 303 are made of polypropylene. The inner wall of the inner layer 303 is fixedly connected to the outer wall of the insulating layer 4.

[0024] Working principle:

[0025] Corrosion-resistant MPP power pipe connection:

[0026] After multiple anti-corrosion MPP power pipes (pipes made of modified polypropylene) are fitted onto the outer wall of the cable, the outer wall of the front anti-corrosion layer 301 is inserted into the inner wall of the rear collar 1. Then, the inner wall of the arc plate 203 is fitted into the top of the outer wall of the collar 1. Next, bolts 202 are threaded onto the top left and right sides of the arc plate 203. Note that the bolts 202 on both sides should not be turned individually. After rotating the left bolt 202 two turns, rotate the right bolt 202 two turns to ensure that the bolts 202 descend in a consistent manner to prevent misalignment and jamming. Continue until the outer wall of the bolt 202 is completely inserted into the top round opening of the base 201. At this time, the base 201 and the arc plate 203 clamp the collar 1 to prevent the inserted power pipe from coming off and improve the connection strength at the collar 1.

[0027] Corrosion-resistant MPP power pipe protection:

[0028] Both the inner layer 303 and the thickened layer 302 are made of polypropylene. The increased wall thickness improves their compressive strength. Meanwhile, the anti-corrosion layer 301 on the outer wall of the thickened layer 302 is made of modified polypropylene, which has stronger corrosion resistance than polypropylene and effectively prevents acid and alkali corrosion. The insulation layer 4 on the inner wall of the inner layer 303 provides good insulation through its own polyimide film and is also resistant to high temperatures.

[0029] Example 2:

[0030] Please see Figure 1-4 In this embodiment, a corrosion-resistant MPP power pipe also includes a convex plate 6. The right side of the convex plate 6 is fixedly connected to the left side of the base 201, and the outer wall of the convex plate 6 is inserted into the inner wall of the groove plate 5.

[0031] Working principle:

[0032] When multiple anti-corrosion MPP power pipes are placed, the outer wall of the convex plate 6 can be inserted into the groove plate 5 on the right side of the adjacent base 201. At this time, the two bases 201 are spliced ​​together, so that multiple anti-corrosion MPP power pipes can be placed flat.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
