Description

Technical Field

[0001] The present application relates to the field of electrical installation technology, and in particular to a safety connection device for high-voltage line installation. Background Art

[0002] In the grand blueprint of the power industry, the erection of high-voltage lines undoubtedly plays a vital role. Its safety and stability are not only the cornerstone of the reliable operation of the power grid, but also an important guarantee for the safety of people's lives and property. With the growing demand for electricity and the continuous expansion of the power grid, the erection and connection technology of high-voltage lines is facing unprecedented high standards and severe challenges.

[0003] As the main artery of power transmission, the construction of high-voltage lines often spans thousands of mountains and rivers, involving long distances, high altitudes and complex and changeable geographical environments. However, in the existing technical system, although the connection devices of high-voltage lines have been developed, there are still limitations that cannot be ignored. The traditional connection method mainly relies on two rotating claws to fix the two sections of high-voltage lines and directly connect their wire harness cores. This design seems to be powerless when dealing with complex situations in actual operation. Due to the considerable length and weight of the high-voltage line itself, coupled with the continuous effect of adverse factors such as wind pressure, rain and snow in the natural environment, it often causes the middle section of the high-voltage line to sag, which in turn aggravates the stress concentration at the connection. In the long run, the connection is not only easy to loosen, but may even cause serious faults such as short circuits, posing a threat to the safe operation of the power grid; more importantly, the traditional high-voltage line connection device is difficult to withstand the huge impact force in extreme weather or emergencies in terms of connection strength, increasing the risk of fracture at the connection. In addition, these devices are also powerless when fixed to the tower body, and are prone to cause a series of problems due to loose fixation, further affecting the stability and reliability of the power grid. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a safety connection device for high-voltage line installation to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0006] A safety connection device for high-voltage line installation comprises two high-voltage lines and two raised rings, wherein the outer walls of the opposite ends of the two high-voltage lines are respectively integrally formed with the inner circles of the two raised rings, and a safety connection structure is provided at the connection between the two high-voltage lines. The safety connection structure consists of a connecting mechanism, an auxiliary mechanism, a sealing mechanism and a fixing mechanism.

The insides of the four grooves are respectively clamped and connected with the two ends of the outer walls of the two raised rings. The opposite ends of the four connecting blocks are respectively integrally formed with the outer walls of the two upper clamping rings and the two lower clamping rings, and are bolted to each other. The inner walls of the four groups of connecting blocks are respectively integrally formed with the connecting ends of the two upper clamping rings and the two lower clamping rings, and are locked and connected by the four fastening bolts.

[0008] Furthermore, the auxiliary mechanism includes two reinforcement cylinders and two L-shaped blocks, the inner walls of the two reinforcement cylinders are tightly fitted with the outer walls of the two high-voltage wires, and the bottoms of the opposite ends are integrally formed with the two lower retaining rings, and the tops are tightly fitted with the two upper retaining rings, the bottoms of the two L-shaped blocks are respectively welded to the surfaces of the two reinforcement cylinders, and the opposite ends are respectively bolted to the outer walls of the two upper retaining rings.

[0009] Furthermore, the sealing mechanism includes an insulating gasket, two protrusions and a ring. The insulating gasket has two protrusions on both sides, and is fitted with the opposite ends of the two upper clamping rings and the two lower clamping rings. The outer walls of the two protrusions are fitted with the inner walls of the two raised rings respectively. The ring is arranged at the connection between the two high-voltage wires and is arranged inside the connecting mechanism.

[0010] Furthermore, the fixing mechanism includes four side rods, two bottom rods and a plurality of mounting holes. The top ends of the four side rods are respectively welded to the side walls of the two reinforcement tubes, and the bottom ends are respectively integrally formed with the two ends of the surface of the two bottom rods. The surfaces of the two bottom rods are provided with a plurality of mounting holes at equal intervals.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model designs a high-voltage line connection device, the core of which is to use two raised rings and four grooves specially provided on the outer walls of two high-voltage lines to achieve a clamping connection. This innovative design enables the separated ends of the two raised rings to fit tightly against the opposite ends of the two reinforcement tubes, significantly enhancing the stability of the connection. Through the mutual bolt connection of the four connecting blocks and the locking effect of the four fastening bolts on the two upper clamping rings and the two lower clamping rings, the device realizes an efficient and firm connection between the two high-voltage lines. This multiple locking mechanism effectively avoids the safety hazards such as short circuit and open circuit caused by loosening or falling off of the traditional connection method, and ensures the long-term stability of the high-voltage line connection.

This design not only simplifies the installation process, but also realizes the dual fixed connection between the connecting device and the tower body, so that the high-voltage line is not only stable and not loose at the connection point, but also can cooperate closely with the tower body, further tightening the high-voltage line, effectively preventing the sagging phenomenon caused by environmental factors such as deadweight or wind pressure, thereby ensuring the safe and stable operation of the power grid.

[0014] 3. The utility model provides excellent insulation and sealing performance for the connection by introducing a sealing mechanism, especially the combined use of an insulating pad and a ferrule, effectively preventing impurities such as water vapor and dust from entering the connection, and further improving the safety and reliability of the connection device.

[0015] 4. The utility model can significantly improve the overall performance and stability of the power grid by using a safe connection structure to connect high-voltage lines.

At the same time, the device also has a certain degree of tensile and compression resistance, which can alleviate the line deformation and stress concentration problems caused by temperature changes, wind force and other factors to a certain extent, and extend the service life of the high-voltage line.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] Example:

[0024] See also Figure 1 , Figure 3 , a safety connection device for high-voltage line erection, including two high-voltage lines 1 and two raised rings 2, the outer walls of the opposite ends of the two high-voltage lines 1 are respectively formed in one piece with the inner circles of the two raised rings 2; the high-voltage lines 1, as the core carrier of power transmission, bear the heavy responsibility of efficiently and stably transmitting electric energy to a wide area, and are an indispensable key element in the modern power grid system. With their excellent conductivity and strong carrying capacity, they ensure that electric resources can reach every corner safely and reliably across long distances, providing a continuous source of power support for people's lives, work and the prosperity and development of society. Two integrated raised rings 2 are designed at the corresponding ends of the two high-voltage lines 1, which are naturally integrated with the outer wall of the high-voltage line 1, not only ensuring the indestructible connection, but also greatly promoting the convenience of installation of the subsequent safety connection structure 3. Through this design, the two high-voltage lines 1 can be connected to each other in a stable and safe way, effectively ensuring the continuity and stability of power transmission, and providing a solid guarantee for the overall operation of the power grid system.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4A safety connection device for high-voltage line erection, a safety connection structure 3 is provided at the connection of two high-voltage lines 1, and the safety connection structure 3 consists of a connection mechanism 31, an auxiliary mechanism 32, a sealing mechanism 33 and a fixing mechanism 34; the connection mechanism 31 includes two upper clamping rings 311, two lower clamping rings 312, four connection blocks 313, four sets of connecting blocks 314, four fastening bolts 315 and four grooves 316; the auxiliary mechanism 32 includes two reinforcement cylinders 321 and two L-shaped blocks 322; the sealing mechanism 33 includes an insulating pad 331, two protruding pieces 332 and a ring 333; the fixing mechanism 34 includes four side rods 341, two bottom rods 342 and a plurality of mounting holes 343.

[0026] Among them, the connection mechanism 31 successfully achieves an efficient and stable connection between two high-voltage wires 1 through its unique design and precise structure. The connection mechanism 31 is mainly composed of two symmetrical components: two upper snap rings 311 and two lower snap rings 312. The design of these four snap rings is exquisite in that their inner walls are all provided with four grooves 316, and the shape and size of these grooves 316 match the outer walls of the two raised rings 2 at the ends of the high-voltage wire 1, thereby achieving the precision and firmness of the clamping connection. When the raised rings 2 of the two high-voltage wires 1 are respectively inserted into the grooves 316 of the corresponding upper snap rings 311 and the lower snap rings 312, a tight connection that cannot be easily loosened will be formed between them. In order to further enhance the stability of the connection, the connection mechanism 31 is also equipped with four connection blocks 313. The opposite ends of the four connection blocks 313 are respectively integrally formed with the outer walls of the two upper snap rings 311 and the two lower snap rings 312, and are tightly connected by bolt connection. This design not only simplifies the installation process, but also enables the entire connection mechanism 31 to resist together as a whole when subjected to external forces, thereby improving the reliability of the connection. In addition, the connection mechanism 31 also uses four sets of connecting blocks 314 and four fastening bolts 315 as additional reinforcement measures. The inner walls of the four sets of connecting blocks 314 are respectively integrally formed with the connecting ends of the two upper clamping rings 311 and the two lower clamping rings 312, providing a stable installation foundation for the fastening bolts 315. When the four fastening bolts 315 are tightened one by one, they will further lock the upper clamping ring 311 and the lower clamping ring 312 together through the connecting blocks 314, forming an indestructible connection barrier.

[0027] Among them, the design focus of the auxiliary mechanism 32 is to enhance the connection strength between the high-voltage line 1 and the connecting mechanism 31 through reinforcement and additional support, and to improve the overall performance and safety of the device, providing a solid and reliable guarantee for power transmission. The reinforcement cylinder 321 is the core component of the auxiliary mechanism 32, and there are two of them, corresponding to the two high-voltage lines 1 respectively. The inner wall of each reinforcement cylinder 321 fits tightly with the outer wall of the high-voltage line 1, and the inner part of the opposite end is engaged with the raised ring 2 to ensure the effective transmission and dispersion of force, protecting the high-voltage line 1 from damage. The inner bottom of the opposite ends of the two reinforcement cylinders 321 is integrally formed with the separated ends of the two lower snap rings 312, which means that the connection between them is strong and seamless, which enhances the overall stability. The inner top of the opposite ends of the two reinforcement cylinders 321 fits tightly with the separated ends of the two upper snap rings 311, providing additional support through physical contact. The L-shaped block 322 serves as a connecting bridge between the reinforcement cylinder 321 and the upper snap ring 311, playing an important role in fixing and strengthening. Its bottom end is firmly connected to the surface of the reinforcement tube 321 by welding, ensuring the strength and stability of the connection. The opposite end of the L-shaped block 322 is connected to the outer wall of the upper retaining ring 311 by bolts. This detachable design facilitates installation and maintenance, and also allows the degree of tightening to be adjusted according to actual conditions, and significantly enhances the connection stability between the high-voltage line 1 and the main fixing mechanism 34, reducing the risk of loosening and falling off due to factors such as wind and vibration. In addition, multiple L-shaped blocks 322 can be designed to facilitate fine-tuning and optimization according to actual conditions on site. For example, in areas with strong winds or strong vibrations, the number of L-shaped blocks 322 can be appropriately increased to enhance the fixing effect between the reinforcement tube 321 and the upper retaining ring 311. In areas where space is limited or the structure needs to be simplified, the number of L-shaped blocks can be reduced to meet specific installation requirements.

[0028] Among them, the sealing mechanism 33 plays a vital role. It not only ensures the electrical insulation performance of the high-voltage line connection, but also enhances the overall sealing of the structure to prevent the external environment from causing adverse effects on the connection. As the core component of the sealing mechanism 33, the insulating pad 331 is made of high-quality insulating material and has excellent electrical insulation performance and mechanical strength. Two convex pieces 332 are designed on both sides of the insulating pad 331. These convex pieces not only enhance the contact area between the insulating pad 331 and the upper and lower clamping rings, but also provide additional fixing force to ensure that the insulating pad 331 can fit tightly on the opposite ends of the clamping ring. The existence of the insulating pad 331 effectively isolates the electrical connection between the high-voltage line 1 connection and the external environment, ensuring the safety of power transmission. The two convex pieces 332 on both sides of the insulating pad 331 are precisely processed to ensure that their outer walls can fit tightly with the inner wall of the raised ring 2. This design not only enhances the sealing performance of the sealing mechanism 33, but also disperses the stress at the connection by increasing the contact points, thereby improving the stability and durability of the overall structure. The presence of the protrusion 332 also makes the installation and adjustment of the insulating pad 331 more convenient, providing great convenience for on-site operations. The ferrule 333 is another important component of the sealing mechanism 33. It is sleeved at the connection between the two high-voltage wires 1 and is located inside the connecting mechanism 31. The ferrule 333 is made of elastic insulating material, has good elasticity and sealing properties, and can tightly wrap the connecting part of the high-voltage wire 1 to prevent moisture, dust and other external impurities from entering. At the same time, the ferrule 333 also plays a certain buffering role, reducing the impact of the high-voltage wire 1 on the connecting mechanism 31 under vibration or wind load, and extending the service life of the equipment.

[0029] Among them, the fixing mechanism 34 is convenient for fixing the connection structure 3 on the tower body through its stable support frame and flexible installation method. The side rods 341 are the main supporting components of the fixing mechanism 34, and there are four of them, which are respectively located on both sides of the reinforcement tube 321. The inner top ends of the four side rods are firmly connected to the side walls of the reinforcement tube 321 through a welding process, ensuring the strength and stability of the connection. The bottom ends of the side rods 341 are integrally formed with the two ends of the surface of the bottom rod 342. This design not only simplifies the manufacturing process, but also enhances the connection strength between the side rods 341 and the bottom rod 342, making the entire fixing mechanism 34 a solid whole. The bottom rod 342 serves as the bottom support of the fixing mechanism 34, and a number of mounting holes 343 are opened on its surface at equal intervals. The design of these mounting holes 343 enables the fixing mechanism 34 to be easily installed on the tower body, and the bottom rod 342 is fixed at a predetermined position by bolts or other fasteners. The number and positions of the mounting holes 343 can be adjusted according to actual needs to meet the installation requirements in different scenarios and provide strong support and fixing effect for the high-voltage line 1 connection device.

[0030] The working principle of the safety connection device for high-voltage line erection is as follows: when in use, the insulating pad 331 and the ferrule 333 are firstly sleeved on the high-voltage line 1, and the two high-voltage lines 1 are connected together, and the ferrule 333 is moved to the connection point of the two high-voltage lines 1, and the upper clamping ring 311 and the lower clamping ring 312 in the connection mechanism 31 will respectively clamp the raised ring 2 on the high-voltage line 1, and then when tightened one by one by the fastening bolts 315, they will further lock the upper clamping ring 311 and the lower clamping ring 312 together through the connecting block 314, forming an indestructible connection barrier; at the same time, the inside of the reinforcement cylinder 321 is fitted with the outer wall of the high-voltage line 1 in advance, and the L-shaped block 322 fixes the reinforcement cylinder 321 with the upper clamping ring 311 by welding and bolt connection. At this time, the four connection blocks 313 are tightly connected by bolt connection, so that the two high-voltage lines 1 are tightly fixed together. This design not only ensures the firmness of the connection, but also facilitates subsequent maintenance and overhaul. Through the synergistic effect of the side rods 341, the bottom rods 342 and the mounting holes 343, the fixing mechanism 34 can ensure that the connection device can still maintain a stable supporting state in a harsh external environment. The design of the mounting holes 343 also enables the fixing mechanism 34 to be fixed on the tower body according to actual needs to adapt to different installation environments and requirements.

[0031] It should be noted that the specific model specifications of the upper retaining ring 311 and the lower retaining ring 312 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
