Magnetic quick butt joint MPP power protection tube

Abstract

This utility model discloses a magnetic quick-connect MPP power protection tube. It relates to the field of protection tube technology and includes a first protection tube and a second protection tube on the left side of the first protection tube. A magnetic ring is connected to the side of the first protection tube near the second protection tube, and a magnetic ring is connected to the side of the second protection tube near the first protection tube. The magnetic poles of the first and second magnetic rings are opposite. The advantage of this utility model is that the cooperation of the first and second magnetic rings allows the first and second protection tubes to be quickly connected and fixed. During this process, multiple positioning blocks enter the positioning groove and compress the pressing block, causing the spring and telescopic column to retract until they are completely submerged in the positioning groove. Then, the spring force drives the pressing block to reset, causing the positioning block and the protection tube to rotate at a small angle, thus locking the positioning block in the positioning groove and further fixing the first and second protection tubes, resulting in a rapid connection.

Description

Technical Field

[0001] This utility model relates to the field of protection tube technology, specifically a magnetic fast docking MPP power protection tube. Background Technology

[0002] MPP power pipes are divided into ordinary type and reinforced type. The reinforced type is further divided into open-cut pipe and trenchless pipe. The so-called MPP trenchless pipe is also known as MPP jacking pipe, MPP traction pipe, MPP power pipe, MPP cable pipe, MPP power cable protection pipe. MPP power pipes are generally butt welded by a welding machine. The fusion point is around 200 degrees Celsius and should not exceed 220 degrees Celsius. Once the temperature is reached, the two ends can be butt-welded. Modified polypropylene power pipes have the characteristics of high temperature resistance and external pressure resistance, and are suitable for high voltage power transmission cable ducts above 10KV.

[0003] In existing technologies, the splicing speed of MPP power protection pipes is relatively slow during the splicing process, and it is very inconvenient to achieve complete alignment. Special tooling is required for adjustment and alignment, which cannot meet the needs of rapid installation of MPP power protection pipes. Therefore, we propose a magnetic quick-connection method for MPP power protection pipes. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic fast-connection MPP power protection tube.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic quick-connect MPP power protection pipe, comprising a first protection pipe, a second protection pipe disposed on the left side of the first protection pipe, a magnetic ring first connected to the side of the first protection pipe near the second protection pipe, and a magnetic ring second connected to the side of the second protection pipe near the first protection pipe. The magnetic poles of the first and second magnetic rings are arranged in opposite directions. A positioning block is connected to the side of the first and second protection pipes that are close to each other. A positioning groove is formed on the side of the first and second protection pipes that are close to each other. The positioning blocks and positioning grooves on the same side are staggered. One end of a telescopic column is connected to the inside of the positioning groove. A spring is disposed on the outside of the telescopic column. A pressing block is connected to the other end of the telescopic column. The pressing block is inclined on the side near the positioning block. A slot is formed on the outside of the first and second protection pipes. Two fastening rings are disposed on the outside of the side of the first and second protection pipes that are close to each other. One end of a telescopic rod is connected to the left and right sides of the bottom fastening rings. A support ring is connected to the other end of the telescopic rod.

[0006] As a further embodiment of this utility model: two retaining rings are connected to each other on the side of the two fastening rings that are close to each other, and the retaining rings and retaining grooves are correspondingly arranged.

[0007] As a further embodiment of this utility model: extension blocks are connected to both the front and rear sides of the two fastening rings, and bolts are threaded through the center of the two extension blocks on the same side, with nuts threaded to the outer bottom of the bolts.

[0008] As a further embodiment of this utility model: one end of the positioning block on the left penetrates through one side of the inner side of the magnetic ring two, and one end of the positioning block on the right penetrates through one side of the inner side of the magnetic ring one.

[0009] As a further embodiment of this utility model: the top side of the support ring is provided with multiple anti-slip textures, and the positioning block and positioning groove are both L-shaped.

[0010] As a further embodiment of this utility model: one end of the spring is connected to the outer wall of the extrusion block, and the other end of the spring is connected to the inner wall of the positioning groove.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] 1. This utility model, through the cooperative arrangement of magnetic ring one and magnetic ring two, enables protective tube one and protective tube two to be quickly connected and fixed. During this process, multiple positioning blocks enter the positioning groove and squeeze the extrusion block, causing the spring and telescopic column to retract until they are completely submerged in the positioning groove. Then, the spring force drives the extrusion block to reset, causing the positioning block and the protective tube to rotate at a small angle, thereby making the positioning block engage in the positioning groove, further fixing protective tube one and protective tube two, and making the connection quick.

[0013] 2. This utility model, through the setting of two support rings, can support the first protective tube and the second protective tube respectively, keeping them on the same reference plane, which facilitates the alignment when the first protective tube and the second protective tube are spliced, and is convenient to use. At the same time, the splicing position of the first protective tube and the second protective tube is protected and fixed by two fastening rings, and the first protective tube and the second protective tube are further tightened by the cooperation of the retaining ring and the retaining groove.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0021] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see the appendix Figure 1 - Appendix Figure 4 This utility model discloses a magnetic quick-connect MPP power protection tube, including a first protection tube 1, a second protection tube 2 disposed on the left side of the first protection tube 1, a magnetic ring 3 connected to the side of the first protection tube 1 near the second protection tube 2, and a magnetic ring 4 connected to the side of the second protection tube 2 near the first protection tube 1. The magnetic poles of the first magnetic ring 3 and the second magnetic ring 4 are arranged in opposite directions. Positioning blocks 5 are connected to the sides of the first protection tube 1 and the second protection tube 2 that are close to each other. Positioning grooves 6 are formed on the sides of the first protection tube 1 and the second protection tube 2 that are close to each other. 5 and positioning groove 6 are staggered. One end of telescopic column 7 is connected to the inside of positioning groove 6. Spring 8 is provided on the outside of telescopic column 7. Compression block 9 is connected to the other end of telescopic column 7. Compression block 9 is inclined on the side near positioning block 5. Slots 10 are opened on the outside of protective tube 1 and protective tube 2. Two fastening rings 11 are provided on the outside of the side of protective tube 1 and protective tube 2 that are close to each other. One end of telescopic rod 16 is connected to the left and right sides of bottom fastening ring 11. The other end of telescopic rod 16 is connected to support ring 17.

[0023] In the first embodiment, two retaining rings 12 are connected to each other on the side of the two fastening rings 11 that are close to each other. The retaining rings 12 and the retaining grooves 10 are set accordingly. Extension blocks 13 are connected to the front and rear sides of the two fastening rings 11. Bolts 14 are inserted through the center of the two extension blocks 13 on the same side. Nuts 15 are threaded to the outer side of the bottom end of the bolts 14. Multiple anti-slip textures are provided on the top side of the support ring 17. The positioning block 5 and the positioning groove 6 are both L-shaped.

[0024] Specifically, two support rings 17 support the first protective tube 1 and the second protective tube 2 respectively. The adjustable setting of the telescopic rod 16 makes it easy to change the support position of the first protective tube 1 and the second protective tube 2 so that the first protective tube 1 and the second protective tube 2 are located on the same reference plane. Then the first protective tube 1 and the second protective tube 2 are spliced ​​together, and the two fastening rings 11 are fixed by bolts 14 and nuts 15, which can be used for splicing protection.

[0025] In embodiment 2, one end of the left positioning block 5 penetrates the inner side of the magnetic ring 2 4, and one end of the right positioning block 5 penetrates the inner side of the magnetic ring 1 3. One end of the spring 8 is connected to the outer wall of the extrusion block 9, and the other end of the spring 8 is connected to the inner wall of the positioning groove 6.

[0026] Specifically, during the assembly process, multiple positioning blocks 5 enter the positioning groove 6 and compress the pressing block 9 in the positioning groove 6, causing the spring 8 and telescopic column 7 to retract until they are completely submerged in the positioning groove 6. Then, the spring force of the spring 8 drives the pressing block 9 to reset, causing the positioning block 5 and the protective tube to rotate at a small angle, thereby making the positioning block 5 engage in the positioning groove 6, further fixing the protective tube 1 and the protective tube 2.

[0027] Working principle:

[0028] In use, the two support rings 17 firstly support the protective tube 1 and the protective tube 2 respectively. The adjustable telescopic rod 16 allows for easy adjustment of the support positions of the two tubes, ensuring they are on the same reference plane. Then, the two tubes are joined together. The magnetic rings 3 and 4 work together to quickly connect and fix the two tubes. During this process, multiple positioning blocks 5 enter the positioning groove 6, compressing the pressing block 9 within the groove, causing the spring 8 and the telescopic column 7 to retract. Once fully submerged in the positioning groove 6, the spring force of the spring 8 drives the pressing block 9 to reset, causing the positioning block 5 and the protective tube to rotate at a small angle, thus locking the positioning block 5 into the positioning groove 6, further fixing the protective tube 1 and the protective tube 2. After fixing, the splicing position of the protective tube 1 and the protective tube 2 is protected and fixed by two fastening rings 11. At the same time, the connection between the protective tube 1 and the protective tube 2 is further reinforced by the cooperation of the retaining ring 12 and the retaining groove 10. Then, the two fastening rings 11 are fixed by the bolt 14 and the nut 15, completing the splicing protection. At this point, the entire process is completed.
