Detailed Description

Referring to fig. 1 to 9, a wind deflection apparatus for a power transmission line of an electric power tower includes:
the same-frequency assembly 3 is arranged on one side, close to the two power transmission lines 1, of the same-frequency assembly and comprises a fixed shaft 4, two wind speed sensors 2 and two buffer mechanisms 12, wherein the fixed shaft 4 is perpendicular to the two power transmission lines 1, the two buffer mechanisms 12 are connected with the fixed shaft 4 in a symmetrical state, and the two wind speed sensors 2 are respectively fixedly connected with two ends of the fixed shaft 4;
Two joint subassemblies 25 link to each other with two buffer gear 12 respectively, every joint subassembly 25 all includes main buckle 26, vice buckle 28, motor 30, damper 36 and two arm of force adjustment mechanism 35, main buckle 26 is articulated with vice buckle 28, solar cell 27 has been linked firmly to one side that vice buckle 28 was kept away from to main buckle 26, motor 30 sets up in the below of main buckle 26 and with solar cell 27 electric connection, two arm of force adjustment mechanism 35 set up in the below of main buckle 26, damper 36 links to each other with two arm of force adjustment mechanism 35.
Because the cable is of a non-rigid structure, the deflection of the transmission line 1 when facing the wind current is a combined movement in the vertical and horizontal direction, and the device needs to recover this deflection. The main buckle plate 26 and the auxiliary buckle plate 28 in the two clamping assemblies 25 are correspondingly buckled and pressed on the two power transmission lines 1 by an operator, the two solar batteries 27 can ensure the endurance of the device, then the two force arm adjusting mechanisms 35 arranged below the main buckle plate 26 can buffer the offset in the vertical direction of the power transmission lines 1 through the damper 36, and the two buffer mechanisms 12 can buffer the offset in the horizontal direction of the power transmission lines 1.
In this process, the two wind speed sensors 2 will detect the wind power, and then transmit the detected signal to the controller, after the controller controls the motor 30 to start, the motor 30 will adjust the arm of force of the damper 36 through the arm adjusting mechanism 35 so as to adapt to different wind powers in the vertical direction, and in this process, the two buffer mechanisms 12 can also adjust so as to adapt to different wind powers in the horizontal direction by the two power lines 1.
To supplement the specific structure of the clamping assembly 25, the following features are specifically provided:
The clamping assembly 25 further comprises a hollowed-out frame 29, a main gear 31, a pinion 32, a screw 33 and a threaded sleeve 34, wherein the hollowed-out frame 29 is fixedly connected with the lower end of the main buckle plate 26, the motor 30 is fixedly connected with one side, far away from the fixed shaft 4, of the hollowed-out frame 29, the main gear 31 is arranged below the motor 30 and is rotationally connected with the hollowed-out frame 29 (as shown in fig. 5), the main gear 31 is fixedly connected with the output end of the motor 30 in a coaxial line, the screw 33 is arranged inside the hollowed-out frame 29 and is rotationally connected with the hollowed-out frame 29, the pinion 32 is fixedly connected with the lower part of the screw 33 in a coaxial line and is meshed with the main gear 31, and the threaded sleeve 34 is in threaded connection with the upper part of the screw 33 and is slidingly connected with the hollowed-out frame 29 (as shown in fig. 9). When the wind speed sensor 2 transmits a detection signal to the controller, and then the controller controls the motor 30 to start and drive the main gear 31 to rotate, the main gear 31 drives the screw 33 to rotate through the auxiliary gear 32, and the screw 33 drives the screw sleeve 34 to move after rotating.
To supplement the specific structure of the arm adjusting mechanism 35, the following features are specifically provided:
The arm adjusting mechanism 35 further includes a main slider 40, a link 41, an auxiliary slider 42, and a U-shaped plate 43, wherein the main slider 40 is fixedly connected with the screw sleeve 34 (refer to fig. 9), one end of the link 41 is hinged with the main slider 40, the other end is hinged with the auxiliary slider 42, and the U-shaped plate 43 is disposed at the upper end of the damper 36 and fixedly connected with the lower end of the auxiliary slider 42. When the screw sleeve 34 moves, the screw sleeve 34 drives the main slide block 40 to move, the main slide block 40 drives the auxiliary slide block 42 to move through the connecting rod 41, and when the auxiliary slide block 42 moves, the U-shaped plate 43 fixedly connected with the auxiliary slide block moves along the damper 36 (refer to fig. 1).
To supplement the specific structure of the damper 36, the following features are specifically provided:
The damper 36 includes a connecting block 37, a rocker arm 38 and two hammer blocks 39, the connecting block 37 is fixedly connected with the lower end of the hollow frame 29 (refer to fig. 8), the middle part of the rocker arm 38 is fixedly connected with the connecting block 37, the two hammer blocks 39 are respectively fixedly connected with two ends of the rocker arm 38, and two U-shaped plates 43 are respectively arranged at the upper ends of the two rocker arms 38. When the U-shaped plate 43 moves, the U-shaped plate 43 can move along the rocker arm 38, at this time, the distance between the U-shaped plate 43 and the hammer 39 is the moment arm of the hammer 39 when the power transmission line 1 is damped, in the process, when the strong wind weather is met, the U-shaped plate 43 should move in the direction away from the hammer 39 to increase the moment arm, so that the damping effect is improved, and when the weak wind or windless weather is met, the U-shaped plate 43 moves in the direction close to the hammer 39 to reduce the moment arm, so that the rocker arm 38 is prevented from being subjected to metal fatigue in continuous vibration.
In this process, the principle of balancing the transmission line 1 and the damper 36 is that the power multiplied by the power arm is equal to the resistance multiplied by the resistance arm. The impact force of the power line 1 on the damper 36 is regarded as resistance, and the force generated by the damper 36 to balance the impact force is regarded as power. When the amplitude of the vibration of the transmission line 1 increases, in order to balance the increased impact force, we need to increase the length of the rocker arm 38 (i.e. the distance between the U-shaped plate 43 and the hammer 39), at which time, by increasing the length of the power arm, the product of the power multiplied by the power arm can be increased, in order to be balanced with the increased resistance (i.e. the increased resistance when the transmission line 1 vibrates) without the power being changed.
To facilitate movement of the U-shaped plate 43, the following features are provided:
The arm adjusting mechanism 35 further includes two pads 44 and two rollers 45, the two pads 44 are symmetrically disposed at the lower end of the U-shaped plate 43 and fixedly connected with the U-shaped plate 43, the two rollers 45 are symmetrically disposed at the upper and lower sides of the rocker arm 38 and are in rolling connection with the rocker arm 38 (refer to fig. 8), and two ends of the rollers 45 are respectively in rotational connection with the two pads 44. When the U-shaped plate 43 moves along the rocker arm 38, the two rollers 45 clamp the rocker arm 38, so that the adjustment speed is prevented from being influenced due to excessive resistance in the moving process of the U-shaped plate 43.

However, the elastic force between the power transmission lines 1 can be changed according to the strength of the wind force by the first spring 24 in the process, and compared with the direct rigid connection of the power transmission lines 1, the first spring 24 can absorb and disperse the impact energy caused by the wind force through the elastic deformation of the first spring, so that the offset amplitude and the swing frequency of the power transmission lines 1 are reduced.
