The rust will weaken the structural strength of the bolts and increase the risk of breakage, thereby causing the risk of the transmission line anti-external damage warning device falling. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned technical problems and provide a transmission line anti-external damage warning device, which can stably position the transmission line anti-external damage warning device, thereby avoiding the risk of the transmission line anti-external damage warning device falling.

[0006] In view of this, the present invention provides a power transmission line anti-external damage warning device, characterized in that it comprises: a power transmission line warning body, a fixing rod fixedly connected to one side of the power transmission line warning body, a fixing frame fixedly connected to the end of the fixing rod away from the power transmission line warning body, two sets of limit devices are provided in the fixing frame, and the limit devices are used to clamp and position the tower;

[0007] The limiting device includes a limiting frame, wherein a first clamping plate and a second clamping plate are symmetrically provided on both sides of the limiting frame, and the first clamping plate and the second clamping plate are moved relative to or toward each other through an adjusting component.

[0008] In this technical solution, the transmission line anti-external damage warning device is installed on the tower through a fixing rod and a fixing frame, and the first clamping plate and the second clamping plate in the limiting device are adjusted so that they can move relative to or toward each other through the adjustment component to achieve precise clamping and positioning of the tower. Since the limiting device is located inside the lower surface of the fixing frame, the limiting device is prevented from being affected by rain erosion, thereby improving the service life of the equipment, thereby preventing the first clamping plate and the second clamping plate from weakening the clamping strength of the tower, which would cause the risk of the transmission line warning body falling.

[0009] In the above technical solution, further, the adjustment component includes:

[0010] A bidirectional screw rod is located on both sides of the interior of the fixed frame, and the first and second clamping plates are sleeved on the left and right ends of the outer wall of the bidirectional screw rod;

[0011] Two guide rods are located on both sides of the bidirectional screw rod, and the first clamping plate and the second clamping plate slide with the outer walls of the two guide rods.

[0012] In the above technical solution, further, one end of the bidirectional screw rod extends and rotates to pass through the limit frame and the fixed frame and is provided with a first knob.

[0013] In this technical solution, the staff drives the rotation of the bidirectional screw by turning the first knob. Under the action of the two guide rods, the first clamping plate and the second clamping plate move toward each other or in a relatively straight line, thereby clamping towers of different thicknesses.

[0014] In the above technical solution, further, a first sliding groove is provided on the inner side of the first splint, a slider slides in the first sliding groove, a socket is provided on the outer side of the slider, a second sliding groove is provided on the inner side of the second splint, a limiting block is moved in the second sliding groove by a moving component, an insert block is provided on the outer side of the limiting block, and the insert block is adapted to the socket.

[0015] In this technical solution, the first clamping plate and the second clamping plate move toward each other to clamp and limit the tower, and at the same time, the insert on the limit block on the inner side of the second clamping plate is inserted into the socket in the slider, thereby further improving the limiting capacity of the limiting device.

[0016] In the above technical solution, further, the moving component includes:

[0017] A threaded rod, one end of which is threadedly inserted into the top of the limit block, and the other end of which is connected to a transmission rod, the outer wall of which is sleeved with a worm gear;

[0018] A worm is rotatably arranged inside the second sliding groove, and the worm is threadedly connected to the worm wheel.

[0019] In the above technical solution, further, one end of the worm extends and rotates through the limit frame and is provided with a second knob.

[0020] In this technical solution, after the first and second splints have completed the positioning of the tower, the plug is also inserted into the socket, and the staff drives the worm to rotate by turning the second knob. The rotation of the worm will drive the worm wheel and the transmission rod sleeved on the worm wheel to rotate, and the rotation of the transmission rod will further drive the threaded rod to rotate. Since one end of the threaded rod is threadedly inserted into the top of the limit block, the rotation of the threaded rod will be converted into the upward movement of the limit block in the second slide groove. While the limit block moves upward, the plug drives the slider to move upward, and finally the upper surface of the plug fits with the lower surface of the tower. The fit between the upper surface of the plug and the lower surface of the tower provides additional supporting force, enhances the safety of the entire early warning device, and reduces the risk of the device falling off due to unstable clamping.

[0021] In the above technical solution, further, the inner side surfaces of the first clamping plate and the second clamping plate are fixedly connected to the outer periphery of the first slide groove and the second slide groove to increase the friction with the contact surface on both sides of the tower and improve the clamping stability.

[0022] In the above technical solution, further, a second anti-slip pad is fixedly connected to the upper surface of the insert block to increase the friction force of the contact surface with the lower surface of the tower.

[0023] In the above technical solution, further, a support sleeve is provided on the outer wall of the fixing rod, and the outer walls on both sides of the support sleeve are connected to support rods, and the other end of the support rod is connected to the fixing frame.

[0024] In this technical solution, the provision of the support sleeve and the support rod enhances the connection stability between the fixing rod and the fixing frame, allowing the entire early warning device to be more firmly installed on the tower, reducing shaking caused by external factors such as wind and vibration.

[0025] The beneficial effects of the utility model are:

[0026] 1. Install the transmission line anti-external damage warning device on the tower through the fixing rod and the fixing frame, adjust the first clamping plate and the second clamping plate in the limit device, and make them move relative to or towards each other through the adjustment component to achieve precise clamping and positioning of the tower. Since the limit device is located inside the lower surface of the fixing frame, the limit device is prevented from being affected by rain erosion, thereby improving the service life of the equipment, thereby preventing the first clamping plate and the second clamping plate from weakening the clamping strength of the tower, which causes the risk of the transmission line warning body falling.

[0027] 2. The upper surface of the plug is fitted with the lower surface of the tower. The fitting of the upper surface of the plug and the lower surface of the tower provides additional support, enhances the safety of the entire early warning device, and reduces the risk of the device falling off due to unstable clamping.

[0039] Example 1:

[0040] Depend on Figure 1-4 As shown, this embodiment provides a power transmission line anti-external damage warning device including: a transmission line warning body 1, a fixed rod 2 is fixedly connected to one side of the transmission line warning body 1, and a fixed frame 3 is fixedly connected to the end of the fixed rod 2 away from the transmission line warning body 1, and two sets of limiting devices 6 are provided in the fixing frame 3, and the limiting device 6 is used to clamp and position the tower; the limiting device 6 includes: a limiting frame 7, and a first clamping plate 8 and a second clamping plate 9 are symmetrically provided on both sides of the limiting interior, and the first clamping plate 8 and the second clamping plate 9 are moved relative to or towards each other through an adjustment component 10. The transmission line anti-external damage warning device is installed on the tower through the fixing rod 2 and the fixing frame 3, and the first clamping plate 8 and the second clamping plate 9 in the limiting device 6 are adjusted so that they can move relative to or toward each other through the adjustment component 10 to achieve precise clamping and positioning of the tower. Since the limiting device 6 is located inside the lower surface of the fixing frame 3, the limiting device 6 is prevented from being affected by rain erosion, thereby improving the service life of the equipment, thereby preventing the first clamping plate 8 and the second clamping plate 9 from weakening the clamping strength of the tower, which causes the risk of the transmission line warning body 1 falling.

[0041] Furthermore, the adjustment assembly 10 includes: a bidirectional screw rod 11, which is located on both sides of the inside of the fixed frame 3, and the first splint 8 and the second splint 9 are sleeved on the left and right ends of the outer wall of the bidirectional screw rod 11; two guide rods 12, the two guide rods 12 are located on both sides of the bidirectional screw rod 11, and the first splint 8 and the second splint 9 slide with the outer walls of the two guide rods 12.

[0042] Furthermore, one end of the bidirectional screw rod 11 extends and rotates through the limiting frame 7 and the fixed frame 3 and is provided with a first knob 13. A worker rotates the first knob 13 to drive the bidirectional screw rod 11, and under the action of the two guide rods 12, the first clamping plate 8 and the second clamping plate 9 move toward each other or linearly relative to each other, thereby clamping towers of different thicknesses.

[0043] Furthermore, the inner side of the first clamping plate 8 is provided with a first sliding groove 14, in which a slider 15 slides, and the outer side of the slider 15 is provided with a socket 16. The inner side of the second clamping plate 9 is provided with a second sliding groove 17, and a limit block 18 is moved in the second sliding groove 17 by a moving assembly 19. The outer side of the limit block 18 is provided with an insert 25, and the insert 25 is adapted to the socket 16. When the clamping plate and the second clamping plate 9 move toward each other to clamp and limit the tower, the insert 25 on the limit block 18 on the inner side of the second clamping plate 9 is inserted into the socket 16 in the slider 15, thereby further improving the limiting capacity of the limiting device 6.

[0044] Furthermore, the moving assembly 19 includes: a threaded rod 23, one end of which is threadedly inserted into the top of the limit block 18, the other end of which is connected to a transmission rod, the outer wall of which is provided with a worm gear 21; a worm 22, which is rotatably disposed inside the second slide groove 17 and is threadably connected to the worm gear 21. One end of the worm 22 extends and rotates through the limit frame 7 and is provided with a second knob 24. After the first clamping plate 8 and the second clamping plate 9 have completed the positioning of the tower, the plug 25 is also inserted into the socket 16, and the staff drives the worm 22 to rotate by turning the second knob 24. The rotation of the worm 22 will drive the worm gear 21 and the transmission rod sleeved on the worm gear 21 to rotate, and the rotation of the transmission rod further drives the threaded rod 23 to rotate. Since one end of the threaded rod 23 is threadedly inserted into the top of the limit block 18, the rotation of the threaded rod 23 will be converted into the upward movement of the limit block 18 in the second slide groove 17. While the limit block 18 moves upward, the plug 25 drives the slider 15 to move upward, and finally makes the upper surface of the plug 25 fit with the lower surface of the tower. The fit between the upper surface of the plug 25 and the lower surface of the tower provides additional supporting force, enhances the safety of the entire early warning device, and reduces the risk of the device falling off due to unstable clamping.

[0045] Furthermore, first anti-slip pads 26 are fixedly attached to the inner surfaces of the first and second clamping plates 8, 9, at the peripheries of the first and second chute grooves 14, 17, to increase friction with the contact surfaces on both sides of the tower and improve clamping stability. Second anti-slip pads 27 are fixedly attached to the upper surface of the insert block 25 to increase friction with the lower surface of the tower.

[0046] Furthermore, the outer wall of the fixing rod 2 is covered with a support sleeve 4, and the outer walls of the support sleeve 4 are connected to support rods 5 on both sides. The other ends of the support rods 5 are connected to the fixing frame 3. The provision of the support sleeve 4 and support rods 5 enhances the stability of the connection between the fixing rod 2 and the fixing frame 3, making the entire early warning device more securely mounted on the tower and reducing shaking caused by external factors such as wind and vibration.
