Description

Technical Field

[0001] This utility model belongs to the field of MPP power pipe technology, and more specifically, it relates to a novel MPP power pipe. Background Technology

[0002] MPP power conduit, also known as MPP pipe, MPP power cable protection pipe, or MPP cable protection pipe, is divided into open-cut and trenchless types. Trenchless MPP pipe is also called MPP jacking pipe or drag pipe. MPP power conduit uses modified polypropylene as its main raw material, featuring high temperature resistance and external pressure resistance, and is suitable for high-voltage power transmission cable ducts below 10KV. MPP power conduit is available in standard and reinforced types. The standard type is suitable for open-cut laying and trenchless crossing projects with a burial depth of less than 4 meters, while the reinforced type is suitable for trenchless crossing projects with a burial depth greater than 4 meters.

[0003] Based on the above, the inventors have discovered the following problems: Most MPP power pipes are usually connected by heat fusion during construction, but this is time-consuming, requires heat fusion equipment, and is not convenient for later maintenance.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a new type of MPP power tube in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effect of this novel MPP power pipe are achieved by the following specific technical means:

[0006] A novel MPP power pipe includes a first power pipe and a second power pipe. A connector 1 is installed at one end of the first power pipe, and a connector 2 is installed at one end of the second power pipe. An installation block is installed on one side of the connector 2. A sealing ring is fitted on the surface of the installation block. The installation block is engaged with the first power pipe. A locking pin assembly is installed between the connector 1 and the connector 2.

[0007] Furthermore, the locking pin assembly includes a set of chambers formed inside the mounting block, a spring is installed inside the chambers, a limiting plate is installed on one side of the spring, and an arc-shaped block is installed on one side of the limiting plate.

[0008] Furthermore, the connector one has a set of arc-shaped grooves inside, a spring two is installed on one side of the arc-shaped groove, a trapezoidal block is installed on one side of the spring two, a sliding groove is opened on one side of the arc-shaped groove, a pull rod is installed on one side of the trapezoidal block, and one end of the pull rod passes through the sliding groove and extends to the outside.

[0009] Furthermore, a mounting hole is provided on one side of the arc-shaped groove, and one end of the arc-shaped block passes through the mounting hole and contacts the trapezoidal block.

[0010] Furthermore, both the first and second power pipes are equipped with support bases at their bottoms, and an upper support ring is installed on the top of the support base. Both the support base and the upper support ring have threaded holes inside, and bolts are installed inside the threaded holes.

[0011] Furthermore, the length of the groove is less than the length of the arc-shaped groove.

[0012] Furthermore, the surfaces of the first and second power pipes are provided with a corrosion-resistant layer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By using the spring, limiting plate, arc-shaped block, and mounting hole in combination, when two power pipes need to be connected as one, press the arc-shaped block. Under the action of the spring, the arc-shaped block moves into the interior of the chamber, and the mounting block is inserted into the first power pipe, thus completing the connection of the two power pipes as one. Through the above design, the connection of power pipes can be completed in a short time, which greatly improves the installation efficiency. At the same time, no complicated tools are required during the installation process, reducing the labor intensity of the workers.

[0015] By using the combined use of the arc-shaped groove, spring II, trapezoidal block, slide, and pull rod, when maintenance, pipe replacement, or pipe layout adjustment of the power conduit is required, pulling the pull rod causes it to slide within the slide. Under the action of spring II, the trapezoidal block moves within the arc-shaped groove, pressing against the arc-shaped block and causing it to disengage from the arc-shaped groove and mounting hole, thus detaching the two power conduits. Then, the pull rod is released, and simultaneously, under the action of spring II, the trapezoidal block returns to its original position. This design greatly improves disassembly efficiency, facilitates power conduit maintenance, enhances the flexibility of pipe layout adjustment, and further improves practicality.

[0016] The use of a corrosion-resistant layer, which is an epoxy resin coating, effectively protects the surface of power pipelines from corrosive substances in the external environment, thereby extending the service life of the power pipelines. Attached Figure Description

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 5As shown:

[0029] This utility model provides a novel MPP power pipe, including a first power pipe 1 and a second power pipe 2. A connector 3 is installed at one end of the first power pipe 1, and a connector 4 is installed at one end of the second power pipe 2. An installation block 5 is installed on one side of the connector 4, and a sealing ring 6 is fitted on the surface of the installation block 5. The installation block 5 is engaged with the first power pipe 1, and a locking pin assembly is installed between the connector 3 and the connector 4.

[0030] The locking assembly includes a set of chambers 7 inside the mounting block 5. A spring 8 is installed inside the chambers 7. A limiting plate 9 is installed on one side of the spring 8, and an arc-shaped block 10 is installed on one side of the limiting plate 9. Through the cooperation of the spring 8, the limiting plate 9, the arc-shaped block 10, and the mounting hole 16, when it is necessary to connect two power pipes into one, pressing the arc-shaped block 10 causes it to move into the chamber 7 under the action of the spring 8, thus locking the mounting block 5 into the first power pipe 1, thereby connecting the two power pipes into one. Through the above design, the connection of power pipes can be completed in a short time, greatly improving the installation efficiency. At the same time, no complicated tools are required during the installation process, reducing the labor intensity of the workers.

[0031] The connector 3 has an arc-shaped groove 11 inside. A spring 12 is installed on one side of the arc-shaped groove 11. A trapezoidal block 13 is installed on one side of the spring 12. A sliding groove 14 is provided on one side of the arc-shaped groove 11. A pull rod 15 is installed on one side of the trapezoidal block 13. One end of the pull rod 15 passes through the sliding groove 14 and extends to the outside.

[0032] The arc-shaped groove 11 has a mounting hole 16 on one side. One end of the arc-shaped block 10 passes through the mounting hole 16 and contacts the trapezoidal block 13. Through the coordinated use of the arc-shaped groove 11, spring 12, trapezoidal block 13, slide groove 14, and pull rod 15, when it is necessary to maintain, replace, or adjust the layout of the power pipe, pull rod 15 is pulled. Pull rod 15 slides in slide groove 14. Under the action of spring 12, trapezoidal block 13 moves in arc-shaped groove 11. Trapezoidal block 13 squeezes arc-shaped block 10, causing arc-shaped block 10 to separate from arc-shaped groove 11 and mounting hole 16, thereby disconnecting the two power pipes. Then, pull rod 15 is released, and trapezoidal block 13 returns to its original position under the action of spring 12. Through the above design, the disassembly efficiency is greatly improved, the maintenance of power pipes is convenient, the flexibility of pipeline layout adjustment is improved, and the practicality is further enhanced.

[0033] The first power pipe 1 and the second power pipe 2 are both equipped with support bases 17 at their bottoms. The top of the support base 17 is equipped with an upper support ring 18. Both the support base 17 and the upper support ring 18 have threaded holes 19 inside. Bolts 20 are installed inside the threaded holes 19. The power pipe is installed on the support base 17, the upper support ring 18 is secured to the power pipe, the bolts 20 are inserted into the threaded holes 19, and then tightened. The support base 17 is used to install the power pipe to the ground, which prevents the power pipe from slipping during the installation process and makes the laying of the power pipe more convenient.

[0034] The length of the slide groove 14 is less than the length of the arc groove 11.

[0035] The first power pipe 1 and the second power pipe 2 are provided with a corrosion-resistant layer. The corrosion-resistant layer is an epoxy resin coating, which can effectively protect the surface of the power pipe from corrosive substances in the external environment and improve the service life of the power pipe.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In use, when laying power conduits, the conduits, due to their circular structure, are prone to rolling on the ground. First, the support base 17 is installed on the ground, then the power conduit is installed on the support base 17. When it is necessary to connect two power conduits, the arc-shaped block 10 is pressed. Under the action of the spring 8, the arc-shaped block 10 moves into the cavity 7, inserting the mounting block 5 into the first power conduit 1, thus completing the connection of the two power conduits. This allows for connection of the power conduits in a short time, greatly improving installation efficiency. Then, the upper support ring 18 is secured to the power conduit, the bolt 20 is inserted into the threaded hole 19, and then tightened. The pull rod 15 is tightened to prevent the power pipe from slipping during installation. When maintenance, replacement, or adjustment of the pipe layout is required, the pull rod 15 is pulled, and it slides in the groove 14. Under the action of the second spring 12, the trapezoidal block 13 moves in the arc groove 11. The trapezoidal block 13 squeezes the arc block 10, causing the arc block 10 to disengage from the arc groove 11 and the mounting hole 16, thereby detaching the two power pipes. Then the pull rod 15 is released, and the trapezoidal block 13 returns to its original position under the action of the second spring 12. This facilitates maintenance of the power pipe, improves the flexibility of pipe layout adjustment, and further enhances practicality.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
