DETAILED DESCRIPTION

[0019] The application is not limited by the following embodiments, and the specific implementation manners can be determined according to the technical scheme of the application and the actual situation.

[0020] In the application, the relative position relationship of each component is described according to the layout mode of the drawings in the description, for example, the position relationship of front, back, top, bottom, left and right is determined according to the layout direction of the drawings in the description. Figure 1 Figure 1 In the application, the relative position relationship of each component is described according to the layout mode of the drawings in the description, for example, the position relationship of front, back, top, bottom, left and right is determined according to the layout direction of the drawings in the description.​​

[0021] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1 like Figures 1-6 As shown, the insulator string for the transmission line includes an insulator string body 100, which includes an insulator string 140. The upper end of the insulator string 140 is provided with a connecting post 130 for connecting with a hook, and the lower end of the insulator string 140 is provided with a sleeve assembly 150 for the transmission line to pass through. Both sides of the connecting post 130 are provided with limiting plates 120 connected to the connecting post 130. The limiting plates 120 are used to cooperate with the angle steel tower to limit the swing amplitude of the insulator string 140.

[0022] In this embodiment, when the construction personnel install the insulator string body 100 on the angle steel tower, they first hang the hook on the angle steel tower, and then connect the connecting column 130 to the hook through the flange 110 and bolts. After the connecting column 130 is connected, the construction personnel pass the transmission line through the sleeve assembly 150 at the lower end of the insulator string 140. When the insulator string body 100 encounters strong winds, it will be blown by the wind and sway. If the swaying amplitude of the insulator string body 100 is too large, the limiting plates 120 on both sides of the connecting column 130 will abut against the angle steel tower to prevent the insulator string body 100 from moving further, thereby preventing the swaying amplitude of the insulator string body 100 from being too large and causing the transmission line to trip.

[0023] In this embodiment, the upper end of the connecting column 130 is provided with a flange 110 that is connected to the hook.

[0024] In this embodiment, after the construction personnel connect the flange 110, they pass the power transmission line through the sleeve 430 in the sleeve assembly 150. Since the power transmission line is relatively long and needs to be laid according to the terrain, it is impossible to guarantee that the power transmission line is in a straight line. The construction personnel can rotate the flange 110 according to different terrains to adjust the fixed position of the flange 110. The rotation of the flange 110 will cause the opening of the sleeve 430 in the sleeve assembly 150 to face the appropriate position, thereby facilitating the passage of the power transmission line.

[0025] In this embodiment, a bird-proof baffle 170 is provided at the lower end of the connecting column 130.

[0026] In this embodiment, the insulator string 140 is positioned below the bird-proof baffle 170. The bird-proof baffle 170 can prevent bird droppings from falling onto the insulator string 140, which could cause line faults such as short circuits or tripping.

[0027] In this embodiment, the flange 110, the bird baffle 170 and the connecting column 130 together constitute a support area for supporting the limiting plate 120; the side wall of the connecting column 130 is provided with a connecting block 310 arranged along the length of the connecting column 130, and the cross-section of the connecting block 310 is T-shaped; one end of the limiting plate 120 is provided with a T-shaped groove 620 for the connecting block 310 to extend into.

[0028] In this embodiment, when installing the connecting block 310, the installer first inserts the T-slot 620 on the limiting plate 120 into the connecting block 310, so that the connecting block 310 extends into the T-slot 620, and the lower end of the limiting plate 120 presses against the bird baffle 170. Then, the flange 110 is fixedly connected to the connecting column 130, thereby restricting the limiting plate 120 within the support area and preventing the limiting plate 120 from shaking or detaching from the connecting column 130.

[0029] The limit plate 120 is made of rubber, which has a good damping effect. At the same time, when the limit plate 120 contacts the angle steel tower, it can play a buffering role and prevent the limit plate 120 from being damaged.

[0030] In this embodiment, the connecting post 130 is provided with a threaded hole 320 along the length of the connecting post 130, and the lower end of the flange 110 is provided with a threaded post 510 extending into the threaded hole 320.

[0031] In this embodiment, the installer can rotate the flange 110 to screw the threaded post 510 at the lower end of the flange 110 into the threaded hole 320 on the connecting post 130, or to screw the threaded post 510 out of the threaded hole 320, thereby facilitating the installation of the flange 110.

[0032] In this embodiment, the lower end of the insulator string 140 is provided with a mounting plate 160, and the sleeve assembly 150 includes a connecting plate 410 connected to the mounting plate 160. The end of the connecting plate 410 away from the mounting plate 160 is provided with a horizontally arranged sleeve 430. A hinge plate 420 is provided between the sleeve 430 and the connecting plate 410, with one end fixedly connected to the sleeve 430 and the other end hinged to the connecting plate 410.

[0033] In this embodiment, since the angle steel towers are built according to the terrain, there are different heights between adjacent angle steel towers. When construction workers are setting up power transmission lines, they can rotate the sleeve 430 so that the sleeve 430 can rotate along the hinge, thereby adjusting the opening direction of the sleeve 430, which makes it easier for construction workers to pass through the sleeve 430.

[0034] In this embodiment, the end face of the limiting plate 120 near the connecting post 130 is an arc-shaped surface 630.

[0035] In this embodiment, the arc-shaped surface 630 on the limiting plate 120 is in contact with the surface of the connecting column 130, thereby preventing damage to the end face of the limiting plate 120 that contacts the connecting column 130 due to the small contact area when the limiting plate 120 contacts the angle steel tower.

[0036] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
