[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] The present invention provides the following preferred embodiments: Embodiment 1, as Figure 1-Figure 9 As shown, an anti-dancing damping spacer for high-voltage cables comprises a main frame 11, a plurality of rocker arms 13, a plurality of wire holding arms 14, a plurality of cable clamps 48, a plurality of adjustment mechanisms and a plurality of anti-dancing mechanisms, a plurality of avoidance grooves 12 are equidistantly provided on the outer wall of the main frame 11, each rocker arm 13 is rotatably arranged inside a avoidance groove 12 through a rotating shaft, each wire holding arm 14 is slidably arranged inside a rocker arm 13, and each cable clamp 48 is installed at one end of a wire holding arm 14; Each anti-dancing mechanism is installed between the main frame 11 and a rocker arm 13, and each anti-dancing mechanism includes a center plate 30, a moving assembly, two side plates 31, two first magnets 38, two second magnets 39, two transmission assemblies and two traction assemblies. The center plate 30 is fixedly arranged between one end of the two side plates 31, and the other end of each side plate 31 is fixedly connected to the main frame 11. The two second magnets 39 are symmetrically fixedly arranged on both sides of a rocker arm 13, and the two first magnets 38 are respectively arranged on the side away from each other of the two second magnets 39. It should be noted here that the magnetic poles of the first magnet 38 and the second magnet 39 at the end close to each other are the same, and the principle of repulsion of the same pole is used, so a resistance can be formed between the first magnet 38 and the second magnet 39; The moving assembly is installed between the center plate 30 and the two first magnets 38. The moving assembly is used to drive the two first magnets 38 to move so that the two first magnets 38 can be synchronously close to or away from the second magnet 39. When the first magnet 38 moves toward the direction close to the second magnet 39, the distance between the first magnet 38 and the second magnet 39 decreases, and the resistance between the first magnet 38 and the second magnet 39 increases. The two traction assemblies are symmetrically arranged on both sides of the end of the rocker arm 13 away from the cable clamp 48, and each transmission assembly is installed between the moving assembly and a traction assembly. When one of the cables begins to dance, the rocker arm 13 swings along with the swing of the cable. At this time, the transmission assembly is driven to work under the action of the traction assembly, so that one of the transmission assemblies can drive the moving assembly to work, so that the first magnet 38 can move in the direction of the second magnet 39, reducing the distance between the first magnet 38 and the second magnet 39, thereby increasing the resistance between the first magnet 38 and the second magnet 39, improving the stability of the rocker arm 13, and improving the anti-dancing effect of the cable. That is, when the cable is affected by external factors and the greater the amplitude of the cable dance, the smaller the distance between the first magnet 38 and the second magnet 39, the greater the resistance. The resistance can be used to offset the force generated by the dancing of the transmission line, reduce the large-scale dancing of the transmission line, and improve the anti-dancing effect of the line.

[0034] Through the transmission assembly, the traction assembly and the moving assembly can achieve a linkage effect, and no matter which side the rocker arm 13 swings to, one of the transmission assemblies can work, and no matter which transmission assembly works, the moving assembly can be driven to operate; Each adjustment mechanism is installed between a rocker arm 13 and a wire holding arm 14. By setting an adjustment component, the position of the wire holding arm 14 in the rocker arm 13 can be adjusted, so that the position of the cable clamp 48 can be adjusted, so that the spacer can be applied to lines with different spacings and has a wide range of applications.

[0035] like Figure 1-Figure 9As shown, the moving assembly includes a swing rod 42, two hinged rods 43, two second slide grooves 36 and two sliding seats 37. The two second slide grooves 36 are symmetrically arranged on both sides of the center plate 30. Each sliding seat 37 is slidably arranged inside a second slide groove 36. The second slide groove 36 is used to guide the sliding seat 37. The two first magnets 38 are respectively installed on the side where the two sliding seats 37 are close to each other. The middle part of the swing rod 42 is rotatably arranged in the middle part of the side of the center plate 30 away from the rocker arm 13. The two ends of the swing rod 42 are respectively rotatably connected to one end of a hinged rod 43, and the other end of each hinged rod 43 is hinged to the surface of a sliding seat 37. When the cable dances, the rocker arm 13 swings with the swing of the cable. At this time, the traction component drives the transmission component to work, so that one of the transmission components can push one of the sliding seats 37 to move in the direction close to the rocker arm 13. Under the action of the swing rod 42 and the two hinged rods 43, one of the sliding seats 37 can drive the other sliding seat 37 to move synchronously when moving, so that the two sliding seats 37 on both sides can move in the direction close to the rocker arm 13. The sliding seat 37 can drive the first magnet 38 to move, reducing the distance between the first magnet 38 and the second magnet 39, thereby increasing the resistance between the first magnet 38 and the second magnet 39, improving the stability of the rocker arm 13, and improving the anti-dancing effect of the cable. That is, when the cable is affected by external factors and the larger the cable dances, the smaller the distance between the first magnet 38 and the second magnet 39, the greater the resistance. The resistance can be used to offset the force generated by the dancing of the transmission line, reduce the situation of large-scale dancing of the transmission line, and the better the anti-dancing effect of the line.

[0036] like Figure 1-Figure 9 As shown, two arc guide rails 22 are symmetrically arranged on both sides of the rocker arm 13, each arc guide rail 22 is fixedly mounted on the main frame 11, each arc guide block 23 is slidably arranged on one arc guide rail 22, and each arc guide block 23 is fixedly connected to the rocker arm 13; When the rocker arm 13 swings due to the dancing of the cable, the rocker arm 13 can drive the arc-shaped guide block 23 to slide inside the arc-shaped guide rail 22 .

[0037] like Figure 1-Figure 9As shown, each transmission assembly includes a wedge block 29, a fixed plate 33, a guide rod 34, a spring 35, a roller 41 and two connecting frames 40. The wedge block 29 is slidably arranged on the side plate 31. The fixed plate 33 is fixedly installed on the end of the side plate 31 away from the main frame 11. The guide rod 34 is slidably arranged on the fixed plate 33. One end of the guide rod 34 is fixedly connected to the wedge block 29. The spring 35 is sleeved on the guide rod 34. The two ends of the spring 35 are respectively connected to the fixed plate 33 and the wedge block 29. One end of the two connecting frames 40 is fixedly connected to a sliding seat 37. The roller 41 is rotatably arranged on the end of the two connecting frames 40 away from the sliding seat 37. The side wall of the roller 41 abuts against the side wall of the wedge block 29. In the initial state, the spring 35 is in a stretched but not fully stretched state, and the roller 41 is in contact with the end of the wedge block 29 close to the spring 35. When the rocker arm 13 swings with the dancing of the cable, the wedge block 29 is driven to move toward the side close to the main frame 11 under the action of one of the traction components. The spring 35 on the wedge block 29 continues to be stretched, and the other traction component does not generate a pulling force on the wedge block 29. At this time, under the action of the spring 35, the wedge block 29 is driven to move toward the side away from the main frame 11, thereby pushing the roller 41 and the sliding seat 37 to move in the second slide groove 36 toward the rocker arm 13.

[0038] like Figure 1-Figure 9 As shown, a first slide groove 32 is provided on the side plate 31 , and the wedge block 29 is slidably arranged inside the first slide groove 32 . The first slide groove 32 is used to guide the wedge block 29 .

[0039] like Figure 1-Figure 9 As shown, each traction assembly includes a connecting rod 28, a through hole 26, a steel rope 25 and a fixing rod 24. The through hole 26 is opened on the main frame 11. The fixing rod 24 is fixedly mounted on one end of the arc-shaped guide block 23. One end of the steel rope 25 is connected to the fixing rod 24. The other end of the steel rope 25 passes through the through hole 26 and is connected to the connecting rod 28. The connecting rod 28 is fixedly mounted on one side of the wedge block 29. When the rocker arm 13 swings due to the dancing of the cable, the arc-shaped guide block 23 swings synchronously with the rocker arm 13, so that the two fixed rods 24 on the arc-shaped guide block 23 swing synchronously. At this time, the wedge block 29 on one side will move toward the direction close to the main frame 11 under the pulling of the steel rope 25, and the spring 35 on one side of the wedge block 29 will continue to be stretched. The wedge block 29 on the other side will not be pulled by the steel rope 25, and the spring 35 corresponding to the wedge block 29 will drive the wedge block 29 to move toward the side away from the main frame 11. That is, no matter which side the rocker arm 13 swings, it can drive one of the wedge blocks 29 to move toward the side away from the main frame 11, thereby driving the movement of the two sliding seats 37, so that no matter which side the cable dances, the cable can be effectively buffered, thereby improving the shock-absorbing effect of the partition on the transmission line and reducing the impact of the line dance on the power system.

[0040] like Figure 1-Figure 9 As shown, a guide wheel 27 for guiding the steel rope 25 is provided on one side of the through hole 26. The guide wheel 27 is installed on the main frame 11 through an adapter block. The guide wheel 27 can guide the steel rope 25 and reduce the friction between the steel rope 25 and the through hole 26. Specifically, the guide wheel 27 is rotatably connected to the adapter block, and the adapter block is fixedly installed on the main frame 11.

[0041] like Figure 1-Figure 9 As shown, each adjustment mechanism includes a first fixed seat 18, a second fixed seat 19, a screw rod 20, and a handle 21. The first fixed seat 18 is fixedly mounted on one side of the rocker arm 13, the second fixed seat 19 is fixed on one side of the wire holding arm 14, the screw rod 20 passes through the first fixed seat 18 and is threadedly matched with the first fixed seat 18, one end of the screw rod 20 is fixedly connected to the handle 21, and the other end of the screw rod 20 is rotatably connected to the second fixed seat 19 through a bearing; When the position of the cable clamp 48 needs to be adjusted, the handle 21 is turned, and the handle 21 can drive the screw rod 20 to rotate. Due to the threaded fit between the screw rod 20 and the first fixed seat 18, the screw rod 20 is rotatably connected with the second fixed seat 19, and at the same time, the wire holding arm 14 is slidably arranged inside the rocker arm 13. Therefore, when the handle 21 is rotated, it can drive the wire holding arm 14 to slide inside the rocker arm 13, so as to adjust the position of the cable clamp 48, so that the distance between two adjacent cable clamps 48 in the spacer rod is adjustable, which can be applied to lines with different spacings and has a wide range of applications.

[0042] like Figure 1-Figure 9 As shown, each cable clamp 48 includes a fixed clamp 15, a movable clamp 16 and a plurality of fixing bolts 17. The fixed clamp 15 is fixedly mounted on one end of the wire holding arm 14, and the movable clamp 16 is located on the side of the fixed clamp 15 away from the wire holding arm 14. The fixed clamp 15 and the movable clamp 16 are detachably connected by a plurality of fixing bolts 17. The inner walls of the fixed clamp 15 and the movable clamp 16 are both installed with fixing bolts 17. During installation, the movable clamp 16 is first removed from the fixed clamp 15, and the cable to be fixed is placed in the groove of the fixed clamp 15. The movable clamp 16 is fixed to the fixed clamp 15 again by the fixing bolts 17, so that the fixed clamp 15 and the movable clamp 16 can fix the cable.

[0043] like Figure 1-Figure 9As shown, two reinforcement rings 44 are provided in the middle of the main frame 11, and a plurality of support rods 45 are fixed equidistantly between the two reinforcement rings 44. The other end of each support rod 45 is fixedly connected to the main frame 11, and a limiting groove 46 is formed between two adjacent support rods 45 and the two reinforcement rings 44. One end of the wire holding arm 14 away from the cable clamp 48 is inserted into the inside of the limiting groove 46. By utilizing the reinforcement ring 44, the overall strength of the spacer can be increased, which is beneficial to improving the service life.

[0044] The specific working process of the present invention is as follows: When the position of the cable clamp 48 needs to be adjusted, the handle 21 is turned, and the handle 21 can drive the screw rod 20 to rotate. Since the screw rod 20 and the first fixing seat 18 are threadedly matched, the screw rod 20 and the second fixing seat 19 are rotatably connected, and at the same time, the wire holding arm 14 is slidably arranged inside the rocker arm 13, so when the handle 21 is rotated, the wire holding arm 14 can be driven to slide inside the rocker arm 13 to adjust the position of the cable clamp 48, so that the spacing between two adjacent cable clamps 48 in the spacer is adjustable, which can be applied to lines with different spacings and has a wide range of applications. During installation, first remove the movable clamp 16 from the fixed clamp 15, place the cable to be fixed in the groove of the fixed clamp 15, and fix the movable clamp 16 to the fixed clamp 15 again by the fixing bolt 17, so that the fixed clamp 15 and the movable clamp 16 can fix the cable; When the cable dances, the rocker arm 13 swings with the cable. When the rocker arm 13 swings due to the dancing of the cable, the arc guide block 23 swings synchronously with the rocker arm 13, so that the two fixed rods 24 on the arc guide block 23 swing synchronously. At this time, the wedge block 29 on one side will move toward the direction close to the main frame 11 under the pull of the steel rope 25, and the spring 35 on one side of the wedge block 29 will continue to be stretched. The wedge block 29 on the other side will not be pulled by the steel rope 25. Under the action of the spring 35 corresponding to the wedge block 29, the wedge block 29 will be driven to move toward the side away from the main frame 11, thereby pushing the roller 41 and the sliding seat 37 to move in the second slide groove 36 in the direction close to the rocker arm 13. Under the action of the hinged rod 43, one of the sliding seats 37 can drive the other sliding seat 37 to move synchronously when moving, so that the two sliding seats 37 on both sides can move towards the direction close to the rocker arm 13, and the sliding seat 37 can drive the first magnet 38 to move, reducing the distance between the first magnet 38 and the second magnet 39, thereby increasing the resistance between the first magnet 38 and the second magnet 39, improving the stability of the rocker arm 13, and improving the anti-dancing effect of the cable, that is, when the cable is affected by external factors and the larger the cable dancing amplitude is, the smaller the distance between the first magnet 38 and the second magnet 39 is, the greater the resistance is, and the force generated by the dancing of the transmission line can be offset by the resistance, reducing the situation of large-scale dancing of the transmission line, and the better the anti-dancing effect of the line; That is, no matter which side the rocker arm 13 swings, it can drive one of the wedge blocks 29 to move toward the side away from the main frame 11, thereby driving the movement of the two sliding seats 37, so that no matter which side the cable dances, the cable can be effectively buffered, thereby improving the shock-absorbing effect of the partition on the transmission line and reducing the impact of the line dance on the power system.

[0045] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
