[0026] The following is combined with Figure 1-9 This application is described in further detail.

[0027] The embodiment of the present application discloses a swing damper.

[0028] Reference Figure 1The swing damper includes a support structure 1 mounted on the inner wall of the tower. In the embodiment of the present application, the support structure 1 can be a beam, a flange or a platform. A number of reinforcing ribs can also be fixedly provided on the support structure 1 to improve the rigidity and strength of the support unit. A swing arm unit is rotatably connected to the support structure 1. The swing arm unit includes a swing arm 2. A number of stacked mass blocks 3 are bolted to the swing arm 2. The operator can remove the mass blocks 3 from the swing arm 2 by disassembling the bolts, so that the number of mass blocks 3 can be set according to the actual size and model of the tower, which is convenient for adjusting the swing frequency of the swing arm 2. A damping unit for controlling the swing amplitude and movement speed of the swing arm unit is provided on the swing arm unit and the support structure 1.

[0029] Therefore, when the swing frequency of the swing damper is adapted to the swing frequency of the tower, the tower will drive the swing arm unit to swing; and when the swing arm unit swings, the inertial force generated by the swing is used to reduce vibration, and the damping unit can control the swing amplitude and movement speed of the swing arm unit, that is, the damping unit is used to control the swing amplitude of the swing arm unit within a controllable range; and under extremely harsh working conditions, as the swing amplitude of the tower increases, the swing amplitude of the swing arm unit will also continue to increase. At this time, controlling the swing amplitude of the swing arm unit through the damping unit can also help improve the stability of the swing damper.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 The damping unit includes a main connecting shaft 4 rotatably connected to the support structure 1, and a swing arm 2 fixedly sleeved on the outer edge of the main connecting shaft 4. In the embodiment of the present application, a bearing can be installed between the support structure 1 and the main connecting shaft 4. The bearing can support and position the main connecting shaft 4 and bear the load, and can reduce friction loss. The main connecting shaft 4 is fixedly sleeved with a main gear 8 at one end away from the support structure. The support structure 1 is also rotatably connected to a slave connecting shaft 6. The slave connecting shaft 6 is fixedly sleeved with a slave gear 9 matching the main gear 8 at one end away from the support structure 1. The main gear 8 and the slave gear 9 are meshed and connected; an electromagnetic component is provided on the slave connecting shaft 6, and the moving part of the electromagnetic component is connected to the slave connecting shaft 6. The electromagnetic component is used to provide resistance when the slave connecting shaft 6 rotates.

[0032] Specifically, the electromagnetic component includes a magnetic part and a conductor part. The moving part of the electromagnetic component is the magnetic part or the conductor part. When the moving part moves, the magnetic part and the conductor part rotate relative to each other to cut the magnetic lines of force and generate a resistance distance. For example, the magnetic part can be a magnetic object such as a disk or a magnet, and the conductor part can be a conductive object such as a conductor shell, a wire winding or a coil. When the conductor part is a wire winding or a coil, an external resistor can be connected to consume energy faster. Therefore, when the magnetic part and the conductor part rotate relative to each other, a resistance distance can be generated due to the movement of cutting the magnetic lines of force.

[0033] Reference Figure 1 and Figure 2 In this embodiment, the arrangement of the electromagnetic assembly is exemplified by taking the conductor as a metal shell 5, preferably a cylindrical metal shell 5, the magnetic component as a disk 7, and the moving part as the disk 7 as an example:

[0034] The cylindrical metal shell 5 is bolted to the supporting structure 1, and the slave connecting shaft 6 is coaxially passed through the metal shell 5 and is rotatably connected to the metal shell 5; the magnetic disk 7 is fixedly sleeved on the outer edge of the slave connecting shaft 6 and the magnetic disk 7 is located as a whole inside the metal shell 5; therefore, when the slave connecting shaft 6 rotates, the magnetic disk 7 will rotate synchronously driven by the slave connecting shaft 6. At this time, the magnetic disk 7 and the metal shell 5 rotate relative to each other to cut the magnetic flux lines, thereby providing resistance to the rotation of the slave connecting shaft 6.

[0035] It should be understood that the moving part can also be a metal shell 5. When the moving part is a metal shell 5, the magnetic disk 7 can be bolted to the supporting structure 1, and the metal shell 5 can be fixedly sleeved on the outer edge of the connecting shaft 6. Then, when the connecting shaft 6 rotates, the metal shell 5 will rotate synchronously driven by the connecting shaft 6. At this time, the magnetic disk 7 and the metal shell 5 will also rotate relative to each other to cut the magnetic lines of force, thereby providing resistance to the rotation of the connecting shaft 6.

[0036] The implementation principle of the embodiment of the present application is: when the swing arm 2 generates a unidirectional two-dimensional swing along the center of the connection point between the swing arm 2 and the support structure 1, the swing arm 2 and the main connecting shaft 4 swing synchronously, and the rotation of the main connecting shaft 4 drives the main gear 8 to rotate. Since the main gear 8 is engaged with the slave gear 9, the slave gear 9 is driven to rotate, thereby driving the slave connecting shaft 6 and the magnetic disk 7 to rotate synchronously. The magnetic disk 7 and the metal shell 5 rotate relative to each other and cut the magnetic lines of force in the magnetic field to generate a resistance distance, thereby realizing the control of the swing amplitude and movement speed of the swing arm 2 and improving the stability of the swing damper.

[0037] Example 2

[0038] Reference Figure 3 and Figure 4The damping unit includes a mounting shaft rotatably connected to the support structure 1 through a joint bearing; the joint bearing is a spherical sliding bearing whose sliding contact surface consists of an inner spherical surface and an outer spherical surface. This structure allows the joint bearing to rotate and swing at any angle during movement. The swing arm 2 is fixedly set on the mounting shaft, and a vertically arranged sliding hole 37 is opened on the swing arm 2. A mounting frame 10 is slidingly connected in the sliding hole 37. A roller 38 is rotatably connected to the surface of the mounting frame 10 facing the swing arm 2. Two slide rails 39 with sizes matching the rollers 38 are bolted to the surface of the swing arm 2 away from the mounting frame 10, and the rollers 38 are rollingly connected between the two slide rails 39; a screw rod 11 is rotatably connected to the inner wall of the tower, and the swing arm 2 swings along the axial direction of the screw rod 11. A screw nut 12 is threadedly connected to the outer edge of the screw rod 11, and the screw nut 12 is fixedly set on the mounting frame 10; the end of the screw rod 11 facing the first casing 13 is coaxially connected to the first rotor shaft 14, and an electromagnetic component is provided on the first rotor shaft 14. The moving part of the electromagnetic component is connected to the first rotor shaft 14, and the electromagnetic component is used to provide resistance when the first rotor shaft 14 rotates.

[0039] Specifically, the setting principle of the electromagnetic component is the same as that of the electromagnetic component in Example 1, and will not be repeated here; Figure 3 and Figure 4 In this embodiment, the arrangement of the electromagnetic assembly is described by taking the first housing 13 as the conductive component and the first winding 16 disposed inside the first housing 13 , the first magnetic steel 15 as the magnetic component, and the moving part as the first magnetic steel 15 as an example:

[0040] The first housing 13 is connected to the support structure 1. The first rotor shaft 14 coaxially passes through the first housing 13 and is rotationally connected thereto. The first magnet 15 is fixedly mounted on the outer edge of the first rotor shaft 14. The first winding 16 is mounted within the first housing 13, with the first magnet 15 entirely located on the inner edge of the first winding 16. Therefore, when the first rotor shaft 14 rotates, the first magnet 15 rotates synchronously with it. At this time, the first magnet 15 and the first winding 16 rotate relative to each other, cutting through the magnetic flux lines, thereby providing resistance to the rotation of the first rotor shaft 14.

[0041] It should also be understood that the moving part can also be the first housing 13 and the first winding 16. In actual operation, the first housing 13 can be fixedly mounted on the outer edge of the first rotor shaft 14, and the first magnet 15 can be fixed on the supporting structure. Such an arrangement can also drive the first magnet 15 and the first winding 16 to rotate relative to each other when the first rotor shaft 14 rotates, thereby cutting the magnetic flux lines and providing resistance to the rotation of the first rotor shaft 14.

[0042] In addition, in this embodiment, the positive and negative poles of the first winding 16 can be short-circuited to increase the reverse torque generated when the damper swings and drives the first rotor shaft 14 to rotate, thereby stopping the swinging damper from swinging, making it easier for subsequent operators to maintain the swinging damper.

[0043] The implementation principle of the embodiment of the present application is: when the swing arm 2 generates a unidirectional two-dimensional swing along the center of the connection point between the swing arm 2 and the support structure 1, the swing arm 2 swings synchronously with the mounting shaft and drives the mounting frame 10 to swing, and the mounting frame 10 drives the lead screw nut 12 to move along the axial direction of the lead screw 11. The lead screw nut 12 moves while driving the lead screw 11 to rotate, and then the rotation of the lead screw 11 drives the first rotor shaft 14 and the first magnet 15 to rotate synchronously. During the rotation process, the first magnet 15 generates an induced current through the interaction of the magnetic field, and then generates a resistance distance to the swing of the swing arm 2, thereby realizing the control of the swing amplitude and movement speed of the swing arm 2, and improving the stability of the swing damper.

[0044] Example 3

[0045] Reference Figure 5 、 Figure 6 and Figure 7 The damping unit includes a first transmission seat 17 rotatably connected to the swing arm 2, a first transmission rod 18 hinged on the first transmission seat 17, a first support frame 19 bolted to the first transmission rod 18, a first support rod 20 ball-hinged on the inner wall of the tower and the first support rod 20 is slidably connected to the first support frame 19. Specifically, the first support rod 20 and the inner wall of the tower can be connected by a joint bearing; a first rack 23 arranged parallel to the first support rod 20 is bolted to the first support rod 20, and a second rotor shaft 26 is rotatably connected to the first support frame 19. The second rotor shaft 26 is fixedly sleeved with a first gear 22 matching the size of the first rack 23 at one end facing the first support rod 20, and the first gear 22 is meshed with the first rack 23; an electromagnetic component is provided on the second rotor shaft 26, the moving part of the electromagnetic component is connected to the second rotor shaft 26, and the electromagnetic component is used to provide resistance when the second rotor shaft 26 rotates.

[0046] Specifically, the setting principle of the electromagnetic component is the same as that of the electromagnetic component in Example 1, and will not be repeated here; Figure 5 、 Figure 6 and Figure 7 In this embodiment, the arrangement of the electromagnetic assembly is described by taking the second housing 21 as the conductor, the second winding 25 disposed inside the second housing 21 , the second magnetic steel 24 as the magnetic component, and the moving part as the second magnetic steel 24 as an example:

[0047] The second housing 21 is fixedly mounted on the first support frame 19. The second rotor shaft 26 passes through the second housing 21 and is rotatably connected thereto. The second magnet 24 is fixedly sleeved on the outer edge of the second rotor shaft 26. The second winding 25 is fixedly disposed within the second housing 21, with the second magnet 24 entirely located on the inner edge of the second winding 25. Therefore, when the second rotor shaft 26 rotates, the second magnet 24 rotates synchronously with it. At this time, the second magnet 24 and the second winding 25 rotate relative to each other, cutting the magnetic flux lines, thereby providing resistance to the rotation of the second rotor shaft 26.

[0048] In addition, in this embodiment, the positive and negative poles of the second winding 25 can be short-circuited to increase the reverse torque generated when the damper swings and drives the second rotor shaft 26 to rotate, thereby stopping the swinging damper from swinging, making it easier for subsequent operators to maintain the swinging damper.

[0049] The implementation principle of the embodiment of the present application is as follows: when the swing arm 2 generates a multi-directional three-dimensional swing along the center of the connection point between the swing arm 2 and the support structure 1, the swing of the swing arm 2 drives the first transmission seat 17 to move, and drives the first transmission rod 18 to move along with the swing of the swing arm 2, so that the first transmission rod 18 drives the first support frame 19 to move; since the first support frame 19 is slidingly connected to the first support rod 20 and the first support rod 20 is ball-hinged with the inner wall of the tower, the movement of the first support frame 19 will drive the first support rod 20 to swing, and the first support frame 19 will drive the first gear 22 to move along the direction of the first rack 23 while moving along the direction of the first support rod 20, and then drive the first gear 22 to rotate, and the rotation of the first gear 22 will drive the second rotor shaft 26 and the second magnet 24 to rotate synchronously, and then the second magnet 24 will generate an induced current through the interaction of the magnetic field during the rotation process, thereby generating resistance to the swing of the swing arm 2, thereby realizing the control of the swing amplitude and movement speed of the swing arm 2, and improving the stability of the swing damper.

[0050] Example 4

[0051] Reference Figure 5 and Figure 8The damping unit includes a second transmission seat rotatably connected to the swing arm 2, a second transmission rod is hinged on the second transmission seat, a second support frame 32 is bolted to the second transmission rod, a second support rod 27 is ball-hinged on the inner wall of the tower, and the second support rod 27 is slidably connected to the second support frame 32, and a plurality of rolling wheels 29 are rotatably connected to the second support frame 32 in turn, a synchronous belt 28 is installed on the second support rod 27, both ends of the synchronous belt 28 are set on the second support rod 27, and the synchronous belt 28 is tightened and wrapped around a plurality of rolling wheels 29 in turn; a third rotor shaft is coaxially connected to one of the rolling wheels 29, and an electromagnetic component is provided on the third rotor shaft, and the moving part of the electromagnetic component is connected to the third rotor shaft, and the electromagnetic component is used to provide resistance when the third rotor shaft rotates.

[0052] Specifically, the setting principle of the electromagnetic component is the same as that of the electromagnetic component in Example 1, and will not be repeated here; Figure 5 and Figure 8 In this embodiment, the arrangement of the electromagnetic assembly is described by taking the third housing as the conductor component and the third winding disposed inside the third housing, the third magnetic steel as the magnetic component, and the third magnetic steel as the moving part as an example:

[0053] The third housing is fixedly mounted on the second support frame 32. The third rotor shaft passes through the third housing and is rotatably connected thereto. A third magnet is fixedly mounted on the outer edge of the third rotor shaft. The third winding is fixedly mounted on the inner edge of the third housing, with the third magnet positioned entirely within the inner edge of the third winding. Therefore, when the third rotor shaft rotates, the third magnet rotates synchronously with it. At this time, the third magnet and the third winding rotate relative to each other, cutting through the magnetic flux lines, thereby providing resistance to the rotation of the third rotor shaft.

[0054] In addition, in this embodiment, the positive and negative poles of the third winding can be short-circuited to increase the reverse torque generated when the damper swings and drives the third rotor shaft to rotate, thereby stopping the swinging damper from swinging, making it easier for subsequent operators to maintain the swinging damper.

[0055] The implementation principle of the embodiment of the present application is: when the swing arm 2 generates a multi-directional three-dimensional swing along the center of the connection point between the swing arm 2 and the support structure 1, the swing of the swing arm 2 drives the second transmission seat position to move, and drives the second transmission rod to move along with the swing of the swing arm 2, so that the second transmission rod drives the second support frame 32 to move. Since the second support frame 32 is slidingly connected to the second support rod 27 and the second support rod 27 is ball-hinged with the inner wall of the tower, the movement of the second support frame 32 drives the second support rod 27 to swing. Since the two ends of the synchronous belt 28 are arranged on the second support rod 27, the second support frame 32 moves along the second support rod 27 while driving several rolling wheels 29 to rotate synchronously. The rotation of several rolling wheels 29 drives the third rotor shaft and the third magnetic steel to rotate synchronously. During the rotation process, the third magnetic steel generates an induced current through the interaction of the magnetic field, and then generates resistance to the swing of the swing arm 2, thereby realizing the control of the swing amplitude and movement speed of the swing arm 2, and improving the stability of the swing damper.

[0056] Example 5

[0057] Reference Figure 5 The damping unit includes a third transmission seat rotatably connected to the swing arm 2, the third transmission seat is hinged with a third transmission rod, the third transmission rod is bolted to the third support frame, the third support rod is ball-hinged on the inner wall of the tower, and the third support rod is slidably connected to the third support frame, and the third support frame is rotatably connected to a plurality of sprockets in turn; a chain is installed on the third support rod, and both ends of the chain are set on the third support rod, and the chain is tightened and wrapped around a plurality of sprockets, the second sprocket and the third sprocket in turn; one of the sprockets is coaxially connected to the fourth rotor shaft, and the fourth rotor shaft is provided with an electromagnetic assembly, the moving part of the electromagnetic assembly is connected to the fourth rotor shaft, and the electromagnetic assembly is used to provide resistance when the fourth rotor shaft rotates.

[0058] Specifically, the setting principle of the electromagnetic component is the same as that of the electromagnetic component in Example 1, and will not be repeated here; Figure 5 and Figure 8 In this embodiment, the arrangement of the electromagnetic assembly is described by taking the fourth housing as the conductor component and the fourth winding disposed inside the fourth housing, the fourth magnetic steel as the magnetic component, and the fourth magnetic steel as the moving part as an example:

[0059] The fourth housing is fixedly mounted on the third support frame. The fourth rotor shaft passes through the fourth housing and is rotatably connected thereto. A fourth magnet is fixedly mounted on the outer edge of the fourth rotor shaft. The fourth winding is fixedly mounted on the inner edge of the fourth housing, with the fourth magnet positioned entirely within the inner edge of the fourth winding. Therefore, when the fourth rotor shaft rotates, the fourth magnet rotates synchronously with it. At this time, the fourth magnet and the fourth winding rotate relative to each other, cutting through the magnetic flux lines, thereby providing resistance to the rotation of the fourth rotor shaft.

[0060] In addition, in this embodiment, the positive and negative poles of the fourth winding can be short-circuited to increase the reverse torque generated when the damper swings and drives the fourth rotor shaft to rotate, thereby stopping the swinging damper from swinging, making it easier for subsequent operators to maintain the swinging damper.

[0061] The implementation principle of the embodiment of the present application is: when the swing arm 2 generates a multi-directional three-dimensional swing along the center of the connection point between the swing arm 2 and the support structure 1, the swing of the swing arm 2 drives the third transmission seat position to move, and drives the third transmission rod to move along with the swing of the swing arm 2, so that the third transmission rod drives the third support frame to move. Since the third support frame is slidingly connected to the third support rod and the third support rod is ball-hinged with the inner wall of the tower, the movement of the third support frame will drive the third support rod to swing; since the two ends of the chain are set on the third support rod, the third support frame will drive several sprockets to rotate synchronously while moving along the third support rod, and the rotation of several sprockets will drive the fourth rotor shaft and the fourth magnet to rotate synchronously. During the rotation process, the fourth magnet will generate an induced current through the interaction of the magnetic field, and then generate resistance to the swing of the swing arm 2, thereby realizing the control of the swing amplitude and movement speed of the swing arm 2, and improving the stability of the swing damper.

[0062] Example 6

[0063] Reference Figure 9 The damping unit includes a fourth transmission seat 33 rotatably connected to the swing arm 2, a conductor rod 34 is hinged on the fourth transmission seat 33, and a guide rail is ball-hinged on the inner wall of the tower; an electromagnetic component is provided between the conductor rod 34 and the guide rail, and the moving part of the electromagnetic component is connected to the conductor rod 34, and the electromagnetic component is used to provide resistance when the conductor rod 34 moves relative to the guide rail.

[0064] Specifically, the electromagnetic component includes a magnetic part and a conductor part. The moving part of the electromagnetic component is the magnetic part or the conductor part. When the moving part moves, the magnetic part and the conductor part are relatively displaced to cut the magnetic lines of force and generate resistance. For example, the magnetic part can be a magnetic object such as a magnet or a magnetic plate, and the conductor part can be a conductive object such as a conductor shell, a wire winding or a coil. When the conductor part is a wire winding or a coil, an external resistor can be connected to consume energy faster. Therefore, when the magnetic part and the conductor part are relatively displaced, resistance can be generated due to the movement of cutting the magnetic lines of force.

[0065] Reference Figure 1 and Figure 2 In this embodiment, the arrangement of the electromagnetic assembly is described by taking the conductor member being a metal conductor frame 35, the magnetic member being a magnetic steel, and the moving part being the conductor frame 35 as an example:

[0066] The conductor frame 35 is bolted to the conductor rod 34, and the conductor frame 35 is slidably connected to the guide rail. The guide rail is a hollow structure and a number of magnets matching the conductor frame 35 are installed inside the guide rail. The guide rail is located at the inner edge of the conductor frame 35. A number of magnet arrays are arranged vertically inside the guide rail, and an induction area is formed between two adjacent magnets; therefore, when the conductor rod 34 drives the conductor frame 35 to move relative to the guide rail under the drive of the swing arm 2, the conductor frame 35 will be displaced relative to the number of magnets to cut the magnetic flux lines and generate resistance, thereby providing resistance to the movement of the conductor rod 34.

[0067] It should be understood that a magnetic steel group can also be set on the conductor frame 35, and conductor blocks can be arranged in an array on the guide rail. Then, when the conductor rod 34 drives the conductor frame 35 to move relative to the guide rail, the magnetic steel group and the conductor blocks on the conductor frame 35 can also produce relative displacement to cut the magnetic flux lines and provide resistance.

[0068] The implementation principle of the embodiment of the present application is: when the swing arm 2 generates a multi-directional three-dimensional swing along the center of the connection point between the swing arm 2 and the support structure 1, the swing of the swing arm 2 drives the fourth transmission seat 33 to move, and then drives the conductor rod 34 to move along with the swing of the swing arm 2, so that the conductor rod 34 drives the conductor frame 35 to move. Since the conductor frame 35 is slidably connected to the guide rail and the guide rail is ball-hinged with the inner wall of the tower; therefore, during the movement, the conductor frame 35 will undergo relative displacement with the magnets arranged inside the guide rail to cut the magnetic lines of force, thereby generating resistance to the swing of the swing arm 2, thereby achieving control of the swing amplitude and movement speed of the swing arm 2, and improving the stability of the swing damper.
