Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to an electric power pipe connecting device. Background Art

[0002] Power pipes are hot-dip coated with PE or epoxy resin, both internally and externally. They offer excellent corrosion resistance, and the coating itself provides excellent electrical insulation, preventing galvanic corrosion. They also have low water absorption, high mechanical strength, and a low friction coefficient, ensuring long-term use. Currently, the connection process for power pipes suffers from poor sealing and installation difficulties, which not only impacts the normal operation of power systems but also poses potential safety risks. Therefore, it is necessary to develop a connection device that can improve the sealing effect of power pipe connections and simplify the installation process.

[0003] The patent with announcement number CN 219659352 U discloses an electric power pipe connection device, including a first electric power pipe and a second electric power pipe. The first electric power pipe and the second electric power pipe are both provided with a first annular groove on their side walls, and a first sealing ring is slidably sleeved inside the two first annular grooves. The connection mechanism includes an upper shell, and the upper filling body is located between the first electric power pipe and the second electric power pipe. When in use, the first electric power pipe and the second electric power pipe can be placed on the lower filling body first, and the two first sealing rings on the first electric power pipe and the second electric power pipe will be inserted into the two second arc-shaped grooves respectively. At this time, the first sealing ring will receive an extrusion force, and under the action of the extrusion force, it will be slightly deformed and retracted into the first annular groove, thereby enhancing the sealing effect of the equipment. Through the design of the first sealing ring and the second sealing ring, the sealing effect of the equipment is better when connected, and the installation and disassembly are more convenient. When the first electric power pipe and the second electric power pipe are damaged, they are convenient to be disassembled and repaired.

[0004] During the construction of power projects, the distance between power pipes is usually not standardized when they are connected to each other. When the above-mentioned device is used, the distance between the two sections of power pipes and the connecting device needs to be consistent to complete the connection operation. This requires manual repeated adjustment, which is particularly difficult when operating larger power pipes. In addition, the above-mentioned connecting device adopts a snap-fit ​​installation method for connection, which fails to take into account the thermal expansion and contraction of the power pipes and the detachment caused by accidental collisions, making it unsafe to use.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
