[0002] Overhead power transmission lines are prone to vibration and galloping due to weather conditions such as wind, ice, and low temperatures. Vibration dampers are typically suspended from the conductors to protect overhead power lines.

[0044] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] See Figure 1 This invention discloses a vibration damping device for power transmission lines, comprising a first L-shaped plate 1, a second L-shaped plate 2, an elastic element 10, and a damping body for reducing vibration of the power transmission line (attached). Figure 1 The structure includes shock absorbers 3 and 4; the first L-shaped plate 1 and the second L-shaped plate 2 are used to fix the shock absorbers on the power transmission line;

[0046] The first L-shaped plate 1 has a first groove 8 in the direction of the horizontal plate. The second L-shaped plate 2 is inserted into the first L-shaped plate 1 by inserting into the first groove. The vertical plate of the first L-shaped plate 1 and the vertical plate of the second L-shaped plate 2 face the same side.

[0047] The first fixed end of the elastic element 10 is fixed to the bottom of the first groove, and the second fixed end of the elastic element 10 is fixed to the wall surface of the horizontal plate of the second L-shaped plate 2 facing the bottom of the groove.

[0048] The vertical plate of the first L-shaped plate 1 or the vertical plate of the second L-shaped plate 2 is detachably connected to the shock absorber at the bottom of the vertical plate in the direction of orientation.

[0049] In this embodiment, the horizontal plates of the two L-shaped plates are inserted together, and the vertical plates face the same direction. An elastic element is provided at the horizontal plate insertion point. In actual use, the two L-shaped plates are clamped onto the power transmission line by the elastic element, thereby fixing the shock absorber connected to the bottom of the L-shaped plates onto the power transmission line. This embodiment, by elastically clamping the two L-shaped plates onto the power transmission line, is applicable to power transmission lines of different sizes, thus having a wide range of applications. In this embodiment, the first L-shaped plate or the second L-shaped plate is detachably connected to the shock absorber. The first L-shaped plate or the second L-shaped plate is elastically connected to the groove of the first L-shaped plate by the elastic element. It can be pre-assembled on the bottom surface and then directly installed at high altitude, eliminating the need for assembly and fixation with bolts and nuts at high altitude as in existing technologies. It is also easy to remove during disassembly and maintenance, improving the efficiency and safety of installation, disassembly, and maintenance.

[0050] In an optional embodiment, it also includes a rotating shaft 11, a sleeve 13, and an extension rod 30;

[0051] The middle part of the vertical plate of the second L-shaped plate 2 is provided with a second groove 7 in the orientation direction of the vertical plate, and the two ends of the rotating shaft 11 are respectively fixed to the two opposite walls of the second groove;

[0052] One end of the sleeve 13 is fixed to the outer wall surface of the rotating shaft 11, and the orientation of the sleeve 13 is the radial direction of the wall surface on which the sleeve 13 is fixed to the rotating shaft 11.

[0053] The inner wall of the sleeve 13 is provided with an internal thread, and the surface of the extension rod 30 is provided with an external thread. The external thread of the extension rod 30 is threadedly connected to the internal thread of the inner wall of the sleeve 13.

[0054] In this embodiment, the extension rod can adjust the length of the sleeve; when the first L-shaped plate and the second L-shaped plate clamp the power transmission line, the shaft is rotated (the direction of rotation is to bring the sleeve closer to the power transmission line) until the sleeve faces the first L-shaped plate and the power transmission line is surrounded between the sleeve, the first L-shaped plate and the second L-shaped plate. The extension distance of the extension rod is adjusted so that the extension rod abuts against the first L-shaped plate to fix the position of the sleeve and the extension rod.

[0055] In yet another optional embodiment, a fixing rod 12, a limiting rod 15, and a push rod 29 are also included;

[0056] One end of the fixing rod 12 is fixed to the outer wall surface of the rotating shaft 11, and the orientation of the fixing rod 12 is the radial direction at the wall surface on the rotating shaft 11 where the fixing rod 12 is fixed.

[0057] The fixed rod 12 and the sleeve 13 have an angle in the radial direction of their projections on the outer wall surface at any point on the rotating shaft 11;

[0058] One end of the limiting rod 15 is fixed to the outer wall surface of the fixed rod 12, and the orientation of the limiting rod 15 is parallel to the axial direction of the rotating shaft 11.

[0059] The target wall in the two opposing walls of the second groove is located on the same side of the fixing rod 12 as the limiting rod 15; the limiting rod 15 is an elastic element that is elastic in its own orientation direction, and the length of the limiting rod 15 in the uncompressed state is greater than the distance between the target wall and the fixing rod 12, and the length of the limiting rod 15 in the fully compressed state is less than the distance between the target wall and the fixing rod 12;

[0060] A limiting hole is provided on the surface of the target wall. The diameter of the limiting hole is greater than or equal to the diameter of the limiting rod 15, and the limiting hole is located on the movement trajectory of the limiting rod 15 as it moves with the rotating shaft 11.

[0061] The limiting hole is a through hole, and the push rod 29 is inserted into the limiting hole at the outlet located on the back side of the target wall. The push rod 29 is used to push out the limiting rod 15 inserted into the limiting hole.

[0062] In this embodiment, the fixing rod fixed on the rotating shaft restricts the rotational movement of the rotating shaft by being inserted into the through hole, while the push rod is used to push the fixing rod out of the through hole from the back to release the restriction on the rotating shaft.

[0063] In another optional embodiment, an arc-shaped groove 14 is provided on the surface of the target wall that coincides with the movement trajectory of the limiting rod 15; this facilitates the smooth movement of the limiting rod along the trajectory.

[0064] In another optional embodiment, the through hole is provided with an enlarged hole, the enlarged hole being away from the target wall surface, and the diameter of the enlarged hole being larger than the diameter of the through hole at the target wall surface;

[0065] The outer wall surface of the push rod 29 has a protrusion located within the enlarged hole. The diameter of the protrusion is larger than the diameter of the through hole at the target wall surface, and the diameter of the protrusion is smaller than the diameter of the enlarged hole. In this embodiment, the protrusion of the push rod within the enlarged hole restricts the push rod from leaving the through hole.

[0066] In yet another alternative embodiment, such as Figure 6 As shown, the shock absorber includes a housing (attached) Figure 6 The components include five plates 3 and a base plate 4), damping ball 19, and multiple universal joint drive shafts 20.

[0067] The damping ball 19 is a hollow sphere located inside the shell, and the interior of the damping ball 19 is filled with a flowable medium.

[0068] One end of each universal joint drive shaft 20 is fixed to the outer surface of the damping ball 19, and the other end is fixed to the inner wall of the housing.

[0069] In this embodiment, the damping ball is filled with a flowable medium, using liquid as the flowable medium. When shaking occurs, the liquid medium in the outer shell of the ball moves in the opposite direction to the shaking, thereby counteracting the shaking amplitude and achieving a damping effect to maintain stability. The amount of flowable medium injected determines the magnitude of the damping force. By increasing or decreasing the amount of liquid medium injected, the damping effect can be increased or decreased to adapt to the usage requirements of different scenarios. Multiple universal joint drive shafts can fix the damping ball inside the housing by fixing it to the inner wall of the housing. At the same time, the damping ball can absorb the vibration transmitted from all directions of the housing to the universal joint drive shafts.

[0070] In another optional embodiment, the connecting shaft of the universal joint drive shaft 20 is telescopic; this can further absorb vibration energy and improve the shock absorption effect.

[0071] In another optional embodiment, it also includes an anemometer 6 disposed on the outer wall of the housing and a processor 24 disposed inside the housing;

[0072] The data transmission terminal of the anemometer 6 is connected to the data input terminal of the processor 24.

[0073] In another optional embodiment, it further includes a power generation component 22 disposed within the housing and a battery 23 for storing the output electrical energy of the power generation component, the power generation component including a rotor that generates electricity by rotating itself and cutting magnetic field lines;

[0074] The anemometer 6 includes a rotating rod (not shown in the attached figure) that rotates with the wind; the rotating rod is fixedly connected to the rotor so that the rotor and the rotating rod rotate synchronously.

[0075] In this embodiment, under the action of wind, the rotating rod of the anemometer 6 rotates, thereby causing the rotor of the power generation component, which rotates synchronously with the rotating rod, to rotate, cutting magnetic field lines to generate electricity, which is stored in the battery and used to power the electrical equipment. In this embodiment, both the power generation component and the anemometer are fixed by a housing, and the rotating rod of the anemometer is fixedly connected to the rotor. When vibration occurs, the housing equipped with damping balls can reduce the impact of vibration on the normal rotation of the rotor of the power generation component, allowing the power generation component to quickly return to a stable power generation state.

[0076] In another optional embodiment, the housing also includes a communication module 25 for establishing a communication connection with a cloud server, an accelerometer 26 for detecting the displacement of the shock absorber, and a locator 27 for detecting the position of the shock absorber; these sensors can be used for monitoring and maintenance of the device.

[0077] Example 2

[0078] Combined with appendix Figures 1-6 A shock-absorbing device for power transmission lines is provided. The shock-absorbing device includes a connecting component and a functional component. The connecting component and the functional component are connected by a detachable connection. A screw 5 is provided between the connecting component and the functional component. Threaded holes that mate with the screw 5 are respectively provided on the first L-shaped connecting plate 1 and the mounting box 3. The connecting component and the functional component are connected by the screw 5 engaging with the threaded holes on both sides.

[0079] The connecting assembly includes a first L-shaped connecting plate 1 and a second L-shaped connecting plate 2 that is slidably fitted with the first L-shaped connecting plate 1. The first L-shaped connecting plate 1 and the second L-shaped connecting plate 2 are combined to form a U-shaped structure with a downward opening. A tensioning mechanism is provided between the first L-shaped connecting plate 1 and the second L-shaped connecting plate 2 to bring the second L-shaped connecting plate 2 closer to the first L-shaped connecting plate 1. The tensioning mechanism includes a tension spring 10 disposed in a slot 8. The extension and retraction direction of the tension spring 10 is the same as the sliding direction of the second L-shaped connecting plate 2. One end of the tension spring 10 is hooked on the second L-shaped connecting plate 2, and the other end is hooked on the first L-shaped connecting plate 1. When installing with the power transmission line, the power transmission line can be directly clamped between the two, and both can be pulled down to allow the power transmission line to spread them apart. The second L-shaped connecting plate 2 is provided with a stop mechanism that is rotatably disposed between the first L-shaped connecting plate 1 and the second L-shaped connecting plate 2. After installation, the stop mechanism is located below the power transmission line.

[0080] The horizontal portion of the first L-shaped connecting plate 1 has a slot 8 that matches the size of the horizontal portion of the second L-shaped connecting plate 2. The bottom surface of the slot 8 has a limiting groove 9. The second L-shaped connecting plate 2 has a limiting block that matches the limiting groove 9, so that the second L-shaped connecting plate 2 slides horizontally along the limiting groove 9.

[0081] The stop mechanism includes a through groove 7 formed in the middle of the longitudinal part of the second L-shaped connecting plate 2. The through groove 7 extends to the bottom surface of the second L-shaped connecting plate 2. A rotating shaft 11 is rotatably provided on the second L-shaped connecting plate 2 and in the through groove 7. The rotating shaft 11 is provided with two adjustable stop rods 13 and a fixing rod 12 arranged at a 90° angle. The adjustable stop rod 13 includes a hollow connecting sleeve. The inner wall of the connecting sleeve is threaded and threaded to an extension rod 131. The end of the extension rod can be adjusted to fit against the first L-shaped connecting plate 1. A corresponding limit control mechanism is provided between the fixing rod 12 and the second L-shaped connecting plate 2.

[0082] The limit control mechanism includes a hollow fixed sleeve 15 mounted on the side wall of the fixed rod 12. A limit post 16 is slidably disposed in the fixed sleeve 15. A first spring 17 is provided on the side of the limit post 16 near the fixed rod 12 in the fixed sleeve 15, causing the head of the limit post 16 to extend out of the fixed sleeve 15. The head of the limit post 16 is semi-circular. An arc-shaped groove 14 matching the size of the fixed rod 12 is formed on the second L-shaped connecting plate 2. A limit hole communicating with the arc-shaped groove 14 is formed in the second L-shaped connecting plate 2. The limit hole matches the size of the limit post 16. An annular cavity communicating with the limit hole is formed in the second L-shaped connecting plate 2. The annular cavity has an insertion hole extending to the outer side of the second L-shaped connecting plate 2 on the side away from the limiting hole. The diameter of the insertion hole is smaller than the diameter of the annular cavity. The second L-shaped connecting plate 2 has a T-shaped push rod 29 that can pass through the insertion hole, the annular cavity and extend into the limiting hole. The T-shaped push rod 29 has an annular plate in the annular cavity that matches its size to prevent the T-shaped push rod 29 from being pulled out. The T-shaped push rod 29 is fitted with a second spring 18 that fits against the side wall of the second L-shaped connecting plate 2. Pressing the T-shaped push rod 29 in will cause it to extend into the limiting hole and push out the limiting post 16, thereby releasing the limiting of the stop mechanism and putting it in a rotatable state.

[0083] The functional components include a mounting box 3, with mounting holes on the bottom surface of the mounting box 3 and a detachable cover 4. The mounting box 3 is equipped with an adjustable shock-absorbing mechanism, and a sensor mechanism is installed on the cover 4.

[0084] The shock-absorbing mechanism includes four sets of retractable universal joint shafts 20 arranged in a cross shape. The four sets of retractable universal joint shafts 20 are respectively installed on the four sides of the mounting box 3, and the ends of the shafts 20 away from the mounting box 3 are connected to hollow spherical shells 19. The spherical shells 19 are filled with a flowable medium. Liquid is used as the flowable medium to achieve a damping effect. The spherical shells 19 are provided with injection pipes that communicate with the interior of the shells. The injection pipes are provided with caps 28 for sealing. The amount of flowable medium injected determines the magnitude of the damping force.

[0085] The sensor mechanism includes an anemometer 6 mounted on the bottom surface of the cover 4, an accelerometer 26 mounted on the top surface of the cover 4, and a locator 27, which are used to detect wind speed, displacement, and positioning, respectively. A support frame 21 is provided on the top surface of the cover 4. The rotating shaft of the anemometer 6 is connected to a rotating rod that passes through the cover via a coupling. A power generation component 22 is mounted on the support frame 21, and the rotor of the power generation component 22 is connected to the rotating rod. The rotation of the anemometer 6 drives the rotating rod to rotate, thereby causing the rotor of the power generation component 22 to rotate and generate electricity. A battery 23, a communication module 25, and a control module 24 are also provided on the top surface of the cover 4. The battery 23 is electrically connected to the power generation component 22 via an analog-to-digital converter. The control module 24 is electrically connected to the battery 23, the anemometer 6, the communication module 25, the accelerometer 26, and the locator 27. A communication connection is established with the background control system through the communication module 25 to realize information transmission.

[0086] Working principle:

[0087] After the device of this invention is transported to the construction site, it is connected to the first L-shaped connecting plate 1 and the second L-shaped connecting plate 2 via screws. The device is then assembled on the bottom surface. After assembly, the device is positioned at the location where the power transmission line needs to be installed. The power transmission line is placed between the first and second L-shaped connecting plates. The second L-shaped connecting plate is pulled to one side to create a gap, allowing the power transmission cable to be inserted. The first L-shaped mounting plate is then pulled down to move the power transmission line to the top. At this point, the device and the power transmission line are suspended. The fixing rod 12 is manually rotated, causing the fixing sleeve 15 on it to rotate along the arc groove 14 until the limiting post extends and engages with the limiting hole. At this point, the stop bar is placed horizontally below the power transmission line, and the extension rod is adjusted so that it extends and its end face is in contact with the side wall of the first L-shaped connecting plate to achieve a stable connection. Under the action of wind, the rotating part of the anemometer 6 rotates, which in turn rotates the connecting rod connected to the rotating part, thereby driving the rotor of the power generation component to rotate, cutting magnetic field lines to generate electricity, which is stored in the battery and used to power electrical equipment. When shaking occurs, the liquid medium in the outer shell of the sphere will move in the opposite direction of the shaking to counteract the shaking amplitude and maintain stability. By increasing or decreasing the amount of liquid medium injected, the damping effect can be increased or decreased to meet the needs of different scenarios.

[0088] Example 3

[0089] See Figure 7 This embodiment discloses a positioning method for a shock absorber device. This method is used in the shock absorber device described in Embodiment 1 or Embodiment 2, and includes:

[0090] 101. When the accelerometer detects a sudden acceleration, and the accelerometer does not detect a new sudden acceleration within a preset time after the current time, the control positioner obtains the position of the shock absorber at a time after the preset time after the current time, and determines the position as the latest position of the shock absorber.

[0091] In this embodiment, when the accelerometer detects a sudden acceleration and the accelerometer does not detect a new sudden acceleration within a preset time after the current time, that is, when the shock absorber is vibrated and no further vibration occurs within a certain time, the position of the shock absorber is repositioned so that the accurate position of the device can be found during subsequent maintenance.

[0092] Optionally, a lower limit can be set for the sudden acceleration. When the vibration of the damping device is small enough that the instantaneous acceleration measured by the accelerometer is less than the lower limit, positioning will not be triggered, thereby reducing the occurrence of frequent positioning due to frequent small vibrations.

Although the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this invention.
