Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line connection, in particular to an overhead power transmission line connection structure. Background Art

[0002] Transmission line towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The materials generally used are Q235 (A3F) and Q345 (16Mn). The rods are connected by rough bolts, which are connected by shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as tower feet are welded from several steel plates into a combination. Therefore, hot-dip galvanizing anti-corrosion, transportation and construction and erection are extremely convenient. For towers with a height of less than 60m, foot nails are set on one of the main materials of the tower to facilitate construction workers to climb the tower;

[0003] In the power industry, aluminum and copper materials with excellent conductivity and low cost are often used to make transmission lines and electrical equipment components. Compared with copper, aluminum has the advantages of low price, low density, and high specific strength. It is often used in large-span transmission lines. Copper itself has better conductivity and is often used in precision electrical equipment, such as transformers, electrical switches, large motors and other equipment. Therefore, in the construction process of power equipment, it is inevitable to encounter connection problems. For this reason, we propose an overhead transmission line connection structure to solve the above problems. Utility Model Content

The first limiting rod 8 and the second limiting rod 9 are both semi-arc structures, and the first limiting rod 8 and the second limiting rod 9 can form a circle, so that they can contact the surface of the wire and play a limiting role.

[0023] Further, see Figure 3 It can be known that the inner top end of the first protective cover 1 is symmetrically fixedly connected with a reset spring 11, and the bottom end of the reset spring 11 is fixedly connected with a second limit rod 9, the second limit rod 9 is a semi-arc mechanism, the first limit rod 8 and the second limit rod 9 are used in conjunction with each other, and the reset spring 11 can limit the second limit rod 9, and the combination of the two facilitates the fixed limiting of the wires.

[0024] Further, see Figure 2 It can be known that a thread groove is provided on the top surface of the first protective sleeve 1, and a threaded rod 3 is inserted into the thread groove. During use, the meshing action between the internal and external threads facilitates the function of limiting and fixing.

[0025] Further, see Figure 2 and Figure 3It can be known that two groups of second limiting rods 9 are provided, and the two groups of second limiting rods 9 are fixedly connected by a connecting fixing rod 10. The connecting fixing rod 10 is located at the bottom end of the threaded rod 3. The connecting fixing rod 10 is pushed to move by the threaded rod 3, so that the two groups of second limiting rods 9 can move simultaneously and approach the first limiting rod 8, thereby limiting the wires.

[0026] Further, see Figure 3 It can be known that a limiting groove is provided inside the fixing block 4, and the limiting rod 7 is inserted inside the limiting groove. The limiting rod 7 and the fixing block 4 are snap-fittedly connected, which can play a role of fixing and limiting during use.

[0027] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, firstly, the first protective cover 1 and the second protective cover 2 are sleeved on the connection port of the electric wire, and then the first protective cover 1 is rotated so that the first protective cover 1 and the second protective cover 2 are engaged with the surface of the electric wire, and then the movable turning handle 5 is rotated, and the rotation of the movable turning handle 5 drives the fixing ring 6 to rotate, and the rotation of the fixing ring 6 drives the limiting plug rod 7 to rotate, so that it is convenient for the limiting plug rod 7 to be inserted into the limiting groove provided on the surface of the fixing block 4, and plays a role of fixing and limiting, and then the threaded rod 3 is rotated, and the threaded rod 3 moves to push the connecting fixing rod 10 to move, and the movement of the connecting fixing rod 10 drives the two sets of second limiting rods 9 to move at the same time, so that it is convenient for people to get close to the first limiting rod 8, so as to play a role of fixing the electric wire;

[0028] When it is necessary to remove the first protective sleeve 1, the threaded rod 3 is rotated counterclockwise, the threaded rod 3 is separated from the surface of the fixed rod 10, and the reset spring 11 is reset by its own contraction force, thereby facilitating the reset of the second limit rod 9. At this time, the movable turning handle 5 is rotated to drive the fixed ring 6 to rotate, and the fixed ring 6 rotates to drive the limit rod 7 to reset and move away from the inside of the fixed block 4, thereby facilitating the hinged opening of the first protective sleeve 1 and the second protective sleeve 2, thereby facilitating the disassembly of the device, and the operation is completed. The above is the entire working principle of the utility model.
