Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an MPP modified polypropylene power cable protection pipe. Background Technology

[0002] MPP power pipes, also known as MPP power cable protection pipes or MPP cable protection pipes, are divided into open-cut and trenchless types. Trenchless MPP power pipes are also called MPP jacking pipes or drag pipes. They use MPP modified polypropylene power cable protection pipes to replace traditional hollow cement pipes.

[0003] In the existing MPP modified polypropylene power cable protection pipes, the pipe bodies are usually hot-melt welded together by a welding machine during the pipe laying process. This can cause cracks in the pipe connection welds, resulting in weak welds during pipe laying and pipe detachment. At the same time, misalignment is prone to occur when pipes are connected, causing the pipes to become loose during installation and reducing the pipe's sealing performance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an MPP modified polypropylene power cable protection pipe, which has the advantages of tight pipe connection and positioning connection, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: an MPP modified polypropylene power cable protection pipe, including a pipe body, a limiting groove is formed on the outer wall of the pipe body, an installation plate is installed on the outer wall of the limiting groove, a fixing block is fixedly connected to the outer wall of the installation plate, a bolt is threadedly connected to the inner wall of the fixing block, a first magnet is fixedly installed at the bottom of the installation plate, a butt plate overlaps the bottom of the installation plate, a second magnet is fixedly installed on the inner wall of the butt plate, a rubber sealing ring is installed on the outer wall of the pipe body, and a locking block is formed on the inner wall of the installation plate.

[0006] As a preferred technical solution of this utility model: the card block is adapted to the outer wall of the rubber sealing ring, and the outer wall of the mounting plate is engaged with the limiting groove.

[0007] As a preferred technical solution of this utility model: the number of the limiting grooves is two, and both limiting grooves are engaged with the outer wall of the mounting plate and the docking plate.

[0008] As a preferred technical solution of this utility model: the diameter of the rubber sealing ring is larger than the diameter of the pipe body, and the rubber sealing ring and the pipe body form a rotatable connection.

[0009] As a preferred technical solution of this utility model: the bolt is connected to the inner wall of the fixing block through the fixing block, and the outer wall of the bolt is threaded with a nut.

[0010] As a preferred technical solution of this utility model: there are several first magnets and several second magnets, and the N poles and S poles of the several first magnets and second magnets correspond to each other.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This MPP modified polypropylene power cable protection pipe, when connected and fitted together, uses a rubber sealing ring that rotates and is placed on the outer wall of the pipe body. The rubber sealing ring overlaps the pipe body and the connection point, giving it good elasticity. When the pipe bodies are connected, under a certain pressure, it tightly fits the connection surface of the pipe body, filling the connection gap. Two limiting grooves are formed with the mounting plate and the docking plate to limit the connection during installation, preventing loosening between the pipe bodies. Bolts are used to connect the fixing blocks through threaded connections, and nuts are rotated through the outer wall of the bolts to achieve quick installation, ensuring a tight connection between the mounting plate and the docking plate through the bolts.

[0012] 2. This MPP modified polypropylene power cable protection pipe uses a mounting plate to make the corresponding surfaces of the first and second magnets of the same polarity, so that the opposite polarities of the first and second magnets attract each other. This allows the mounting plate and the mating plate to be positioned correctly and avoids misalignment during installation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 An MPP modified polypropylene power cable protection pipe includes a pipe body 1, a limiting groove 6 formed on the outer wall of the pipe body 1, an installation plate 2 installed on the outer wall of the limiting groove 6, a fixing block 3 fixedly connected to the outer wall of the installation plate 2, a bolt 4 threadedly connected to the inner wall of the fixing block 3, a first magnet 5 fixedly installed at the bottom of the installation plate 2, a butt plate 8 overlapping the bottom of the installation plate 2, a second magnet 9 fixedly installed on the inner wall of the butt plate 8, a rubber sealing ring 7 installed on the outer wall of the pipe body 1, and a locking block 11 formed on the inner wall of the installation plate 2. In the above structure, the installation of the fixing block 3 provides stable support between the bolt 4 and the nut 10, thereby increasing the stability during the installation and connection of the equipment and achieving a tight connection.

[0017] In a preferred embodiment: the locking block 11 is adapted to the outer wall of the rubber sealing ring 7, and the outer wall of the mounting plate 2 is engaged with the limiting groove 6; In the above structure, the mounting plate 2 and the docking plate 8 overlap, the mounting plate 2 and the docking plate 8 abut against the rubber sealing ring 7, and the mounting plate 2 and the docking plate 8 are engaged with the limiting groove 6 to achieve limiting, so that the locking block 11 and the rubber sealing ring 7 are tightly connected, and the rubber sealing ring 7 prevents external dust, moisture and other pollutants from entering the interior between the pipe body 1 and the pipe body.

[0018] In a preferred embodiment: there are two limiting grooves 6, and both limiting grooves 6 are engaged with the outer walls of the mounting plate 2 and the docking plate 8. In the above structure, both limiting grooves 6 are engaged with the outer walls of the mounting plate 2 and the docking plate 8. The mounting plate 2 and the docking plate 8 form an installation limit between the pipe body 1 and the pipe body 1, so as to avoid the connection between the pipe body 1 and the pipe body 1 becoming loose during the installation process, which would result in an unstable installation.

[0019] In a preferred embodiment: the diameter of the rubber sealing ring 7 is larger than the diameter of the tube body 1, and a rotatable connection is formed between the rubber sealing ring 7 and the tube body 1; In the above structure, when the tubes 1 are connected and fitted together, the rubber sealing ring 7 is rotated and placed on the outer wall of the tube 1. The rubber sealing ring 7 overlaps the connection between the tubes 1 and the tubes 1, so that the rubber sealing ring 7 has good elasticity. When the tubes 1 are connected, under a certain pressure, the rubber sealing ring 7 will undergo elastic deformation, tightly fit the connection surface of the tubes 1, fill any possible tiny gaps, and thus effectively prevent fluid from seeping in from the connection of the tubes 1, ensuring the sealing and integrity of the tubes 1.

[0020] In a preferred embodiment: the bolt 4 is connected through the fixing block 3 to the inner wall of the fixing block 3, and the outer wall of the bolt 4 is threaded with a nut 10; In the above structure, when the mounting plate 2 and the docking plate 8 are connected by external force, the bolt 4 is used to make a threaded connection between the fixing block 3 and the fixing block 3. The nut 10 is rotated through the outer wall of the bolt 4 to achieve quick installation, so that the mounting plate 2 and the docking plate 8 can be quickly assembled and disassembled through the bolt 4, the connection is tight and the firmness is increased.

[0021] In a preferred embodiment: there are several first magnets 5 and second magnets 9, and the N poles and S poles of the several first magnets 5 and second magnets 9 correspond to each other; In the above structure, by aligning the N and S poles of several first magnets 5 and second magnets 9, the mounting plate 2 causes the corresponding surfaces of several first magnets 5 and several second magnets 9 to be of the same polarity, so that there is attraction between opposite polarities between the first magnets 5 and second magnets 9, thereby achieving positioning between the mounting plate 2 and the docking plate 8 and avoiding misalignment.

[0022] Working principle: When the pipe body 1 is connected and fitted together, the rubber sealing ring 7 is rotated and placed on the outer wall of the pipe body 1. The rubber sealing ring 7 overlaps with the connection point of the pipe body 1, giving it good elasticity. When the pipe body 1 is connected, under a certain pressure, the rubber sealing ring 7 will undergo elastic deformation, tightly fitting the connection surface of the pipe body 1 and filling any possible tiny gaps. This effectively prevents fluid from seeping in from the connection point of the pipe body 1, ensuring the sealing and integrity of the pipe body 1. The mounting plate 2 and the docking plate 8 overlap, and the mounting plate 2 and the docking plate 8 abut against the rubber sealing ring 7. The mounting plate 2 and the docking plate 8 engage with the limiting groove 6 to achieve limiting, making the locking block 11 and the rubber sealing ring 7 tightly connected. Through the two limiting mechanisms... The grooves 6 are engaged with the outer walls of the mounting plate 2 and the docking plate 8. The mounting plate 2 and the docking plate 8 form an installation limit between the pipe body 1 and the pipe body 1, preventing loosening of the connection between the pipe body 1 and the pipe body 1 during installation. The bolts 4 are used to connect the fixing blocks 3 through the threaded connection. The nuts 10 are rotated through the outer wall of the bolts 4 to achieve quick installation. The mounting plate 2 and the docking plate 8 can be quickly assembled and disassembled through the bolts 4, and the connection is tight. By aligning the N and S poles of several first magnets 5 and second magnets 9, the mounting plate 2 drives the corresponding surfaces of several first magnets 5 and several second magnets 9 to be of the same polarity, so that there is an attraction between opposite polarities of the first magnets 5 and second magnets 9. This achieves positioning between the mounting plate 2 and the docking plate 8 and avoids misalignment.
