Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of protection pipe, especially to a polyethylene power threading protection pipe that eliminates port scratches. BACKGROUND

[0002] Polyethylene power threading protection pipe plays a crucial role in the field of electric power engineering. It is a kind of pipe device specially used for protecting power cables during laying and use. Its advantages are obvious. Polyethylene material itself has good insulation performance, which can effectively prevent power cables from leaking due to contact with the external environment and other safety accidents, ensuring the safety of power transmission. At the same time, it has strong corrosion resistance. Whether in a humid underground environment or in a special area with acid and alkali chemical substances, it can maintain the integrity of the pipe for a long time, thereby providing stable protection for the internal cable. Its weight is relatively light, which is convenient for construction personnel to carry and install, improves the construction efficiency of electric power engineering, and reduces the construction cost.

[0003] In the prior art, polyethylene power threading protection pipe usually adopts a relatively simple connection method, such as some traditional sleeve connection. During the connection process, two pipes are usually only basically sleeved. The working process is mainly to insert one end of one pipe into the interface of the other pipe, and then complete the connection operation by tightening the bolt or buckling the sleeve. This connection method can meet the basic cable protection requirements in a relatively stable environment.

[0004] However, this traditional connection method has certain defects. When the equipment needs to be carried or moved, the two ends of the pipe are easy to rub with other components or the ground, causing scratches on the port. These scratches not only damage the appearance of the pipe, but more importantly, they may damage the structural integrity of the pipe, thereby affecting the connection tightness and stability between the two devices, such as causing the sealing performance of the connection to decrease, allowing moisture, dust and other impurities to enter the pipe, causing damage to the power cable, and in severe cases, even causing power failure, which endangers the safe operation of the entire power system.

[0032] Specifically, in the protection operation of the protection tube 1, first, the two side pull rings 9 are manually pulled, and in the displacement process under the force, the pull rings 9 will produce a linkage effect with the help of the connecting columns 6 connected thereto, the connecting columns 6 will drive the clamping columns 8 to move out from the inside of the clamping grooves 4 pre-provided on one side of the protection tube 1, and in this process, the spring I 7 connected to the clamping column 8 will be extruded due to the movement of the clamping column 8, the spring I 7 gradually occurs elastic deformation and stores elastic potential energy, then the clamping column 8 is moved along the predetermined track to the outer wall position of the clamping groove 4 on the other side of the protection tube 1, at this time, the pulling force on the pull ring 9 is released, and with the help of the rebounding force of the spring I 7, the spring I 7 releases the stored elastic potential energy and pushes the clamping column 8 to be embedded into the inner wall of the other clamping groove 4, through this clamping connection mode, the precise fixing of the position of the protection tube 2 is realized, when the protection tube 2 moves, the rubber protection ring 10 on one side of the protection tube 2 will move to the two ends of the equipment, the rubber protection ring 10 has good elasticity and wear resistance, and it can be tightly fitted on the surface of the two ends of the equipment. In the process of carrying or moving the equipment, the two sides of the rubber protection ring 10 are used to protect the two ends of the equipment, which effectively avoids the phenomenon that the ports of the equipment are scratched due to friction, collision and other situations with external objects, enhances the protection performance of the equipment, and ensures the integrity and safety of the equipment in the process of transportation and storage.

[0033] Referring to Figure 1 and Figure 2The connecting assembly comprises a plurality of clamping balls 13 located at one end of the protection pipe 1. The clamping balls 13 are key locking components and are matched with the grooves on the outer wall of the connecting pipe 17 and are clamped under the action of the second spring 15 to prevent displacement after connection, thereby ensuring reliable and stable connection. The other end of the protection pipe 1 is fixedly connected with the connecting pipe 17, which is an interface for butt joint with pipelines of other devices and is adapted to corresponding systems and cooperates with other components to build a connecting passage, thereby ensuring smooth transmission. The one end of the protection pipe 1 is fixedly connected with the third fixing pipe 11, which provides a mounting base and support for the clamping balls 13 and other components and is a core framework, so that the components work in an orderly manner. The clamping balls 13 are slidingly connected in the third fixing pipe 11 and can be flexibly moved to facilitate clamping into the grooves during connection and moving out during disassembly, thereby realizing convenient operation. The outer wall of the third fixing pipe 11 is fixedly connected with the fixing ring 16 and one end of the second spring 15, thereby providing a force point for the second spring 15 and ensuring stable elastic force. The outer wall of the third fixing pipe 11 is slidingly connected with the baffle 14 located on one side of the clamping balls 13, which is used to limit the position of the clamping balls 13. The baffle 14 blocks the clamping balls 13 when not connected and gives the clamping balls 13 space when connected, thereby orderly controlling the connection function. The inner wall of the third fixing pipe 11 is fixedly connected with the sealing ring 12, which is used to seal the connection between the two devices. The material has elasticity and sealing property and is deformed when connected to fill the gap and prevent leakage. The outer wall of the third fixing pipe 11 is provided with the second spring 15, one end of which is connected to the outer wall of the baffle 14 and the other end of which is connected to the outer wall of the fixing ring 16. The second spring 15 is a key element for providing elastic force. During connection operation, after the baffle 14 is pressed and released, the second spring 15 rebounds to drive the baffle 14 back to the original position and the clamping balls 13 to clamp, thereby simplifying the process and ensuring stable and reliable connection.

[0034] Specifically, when two pipeline connection operations are performed, first, manual pressure is applied to the baffle 14 to move the baffle 14 away from the side of the clamping balls 13 against the original position limitation. In this process, the second spring 15 associated with the baffle 14 is subjected to a pushing force, and the second spring 15 starts to compress and deform, and the elastic potential energy gradually accumulates. Then, the connecting pipe 17 of the other device to be connected is carefully moved into the inner wall of the third fixing pipe 11. In this process, the connecting pipe 17 will exert a squeezing action on the sealing ring 12 previously arranged on the inner wall of the third fixing pipe 11. The sealing ring 12 is made of a material with good elasticity and sealing property and can tightly fit the outer wall of the connecting pipe 17 and the inner wall of the third fixing pipe 11 when subjected to squeezing, thereby effectively filling the small gap between the two and enhancing the sealing property of the connection between the two devices to prevent liquid or gas leakage at the connection. After the connecting pipe 17 is moved to the appropriate position, the external force acting on the baffle 14 is stopped. At this time, the second spring 15 generates a rebounding force by virtue of the stored elastic potential energy to drive the clamping balls 13 to move along the predetermined track until the clamping balls 13 are accurately moved to the groove previously provided on the outer wall of the connecting pipe 17. Through the clamping connection of the clamping balls 13 and the groove, the two devices are quickly connected. This connection method not only is simple and convenient to operate, but also can ensure the stability of the connected structure and meet the use requirements of pipeline connection under different working conditions.

[0035] Working principle: in the process of protecting the two ends of the protection tube 1, pull the pull ring 9 on both sides, the pull ring 9 will be moved by the connecting column 6 to drive the card column 8 from the inside of the card slot 4 to move out, and the spring 7 is extruded, then the card column 8 is moved to the outer wall of the other card slot 4, at this time, the pull ring 9 is released, the spring 7 is used to push the card column 8 to be clamped in the inner wall of the other card slot 4, the position of the protection tube 2 is fixed, at this time, the rubber protection ring 10 on one side of the protection tube 2 is moved to the two ends of the equipment, the rubber protection ring 10 on both sides is used to protect the two ends of the equipment, prevent the equipment port from being scratched in the process of carrying and moving, enhance the protection of the equipment, in the process of connecting two pipes, press the baffle 14, let the baffle 14 move out from the side of the card ball 13, and push the spring 15 to be compressed, at this time, the connecting pipe 17 of the other equipment is moved to the inner wall of the fixed pipe three 11, and the sealing ring 12 is extruded, the sealing ring 12 is used to enhance the sealing of the connecting part of the equipment on both sides, at this time, the pull ring 14 is pulled, the spring 15 is used to push the card ball 13 to move to the recess on the outer wall of the connecting pipe 17, realize the quick connection between two equipment.
