[0017] 1. The energy-dissipating anti-dance device of the present invention, the piston, the first inner cylinder, the energy-dissipating liquid, the flow tube and other components form an inertial volume system. When the piston rod and the piston generate movement along the axial direction, it can be converted into a high-speed flow of the energy-dissipating liquid in the flow tube, thereby realizing efficient energy dissipation. At the same time, since the first inner cylinder is connected to the outer cylinder by a spiral structure, under the push of the piston and the energy-dissipating liquid, the first inner cylinder can move along its own axial direction and generate rotation at the same time. Since the friction plate is always in contact with the friction ring under the action of elastic force, friction energy dissipation is generated, thereby increasing the energy dissipation mode, realizing multiple energy dissipation, and achieving good energy dissipation and vibration reduction effect.

The energy-consuming anti-dancing device of the present invention adopts magnetorheological fluid as the energy-consuming liquid, and a coil is wound around the outer periphery of the first inner cylinder.

[0019] 3. The energy-dissipating and anti-dance device of the present invention has a piston that is larger in the middle and smaller at both ends, and is provided with a conical platform, so that during the movement of the piston, the energy-dissipating liquid can be accelerated to flow to the flow tube, thereby increasing the energy-dissipating effect.

[0020] 4. The energy-dissipating and anti-dance device of the present invention comprises components such as a second inner cylinder, a nut, an iron ball, a first permanent magnet and a baffle, so that when the piston rod moves along its own axial direction, it can drive the nut to rotate, thereby causing the baffle to collide with the iron ball adsorbed on the first permanent magnet, continuously knocking down the iron ball adsorbed on the first permanent magnet, thereby realizing collision energy dissipation, further increasing the energy dissipation mode, and improving the energy dissipation and vibration reduction effect.

[0021] 5. The energy dissipation device of the present invention is provided with an air spring, which, on the one hand, makes up for the problem of reduced stiffness of ordinary springs under repeated extrusion, ensuring that the device can automatically reset. At the same time, when the piston rod squeezes the air spring, the permanent magnets in the additional air cavity will approach each other. Due to the mutual repulsion of magnetism, the permanent magnets will promote the air spring to return to its original state, accelerate the recovery speed, and thus improve the energy consumption efficiency of the entire device.

[0033] For the convenience of description, if the words "upper" and "lower" appear in the present invention, they only indicate that they are consistent with the upper and lower directions of the drawings themselves, and do not limit the structure. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0034] Example 1

[0035] This embodiment provides a multi-adjustable energy dissipation anti-dance device, such as Figure 1-Figure 4 As shown, it includes an outer cylinder 4 and a piston rod 2. The outer cylinder 4 adopts a cylindrical structure or a square structure. In this embodiment, the outer cylinder 4 adopts a cylindrical structure.

[0036] One end of the outer tube 4 is defined as a first end, and the other end is defined as a second end.

[0037] The piston rod 2 extends into the outer cylinder 4 through the first end of the outer cylinder, and the piston rod 2 and the outer cylinder 4 are coaxially arranged. A hole through which the piston rod passes is arranged on the wall of the first end of the outer cylinder 4, and a limiting sleeve 3 is arranged at the hole. The piston rod 2 passes through the limiting sleeve 3 and extends into the outer cylinder 4. The limiting sleeve 3 is used to limit the moving distance of the piston rod 2 and the outer cylinder 4 along the axial direction thereof. Figure 8 As shown, the interior of the limiting sleeve 3 is configured as a hollow structure, and there is an annular baffle 45 in the middle of the hollow structure. The annular baffle 45 is fixedly connected to the piston rod 2. When not subject to external force, the annular baffle is in the middle of the hollow structure. When the piston rod moves up and down, the internal annular baffle 45 encounters the end portion of the limiting sleeve 3 and stops moving, thereby preventing the piston rod 2 from moving up and down too much.

[0038] A first inner cylinder 6 is disposed inside the outer cylinder 4 . The first inner cylinder 6 is also a cylindrical cylinder and is coaxially disposed with the outer cylinder 4 . The piston rod 2 passes through the first inner cylinder 6 along the axial direction of the first inner cylinder 6 .

[0039] Openings through which the piston rod 2 passes are provided on the walls of the two ends of the first inner cylinder 6, and a swivel 9 is provided at the opening. The piston rod 2 is slidably connected to the inner side surface of the swivel 9, so that the piston rod 2 can move along its own axial direction, and relative rotation can be generated between the first inner cylinder 6 and the piston rod 2.

[0040] A sealing process is performed between the rotating ring 9 and the piston rod 2 so that the space inside the partition is a sealed space.

[0041] An annular partition plate 7 is arranged inside the first inner tube 6 . The partition plate 7 is arranged coaxially with the first inner tube 6 , and two ends of the partition plate 7 are fixed to two end tube walls of the first inner tube 6 respectively.

[0042] The partition 7 divides the first inner tube 6 into a space outside the partition and a space inside the partition, and the piston rod 2 passes through the space inside the partition.

[0043] A piston 14 is fixed to the rod section of the piston rod 2 located in the space inside the partition, and the middle portion of the piston 14 fits against the inner side surface of the partition 7 .

[0044] In this embodiment, the cross-sectional size of the piston gradually decreases from the middle to the end of the piston 14. Specifically, the piston 14 adopts a stepped structure, and the cross-sectional size gradually decreases from the middle to the end. Correspondingly, a frustum 15 is provided on the two end walls of the first inner tube 6, wherein the end of the frustum 15 with a larger cross-sectional area is fixed to the end wall of the first inner tube 6.

[0045] The piston 14 partitions the space inside the partition into a first space and a second space.

[0046] A flow tube is fixed on the outer side of the partition 7 . In this embodiment, the flow tube is a spiral tube 8 , which is wound and fixed on the outer side of the partition 7 .

[0047] One end of the spiral tube 8 is connected to the first space, and the other end of the spiral tube 8 is connected to the second space.

[0048] The first inner cylinder 6 is connected to the outer cylinder 4 via a spiral structure. Specifically, spiral tracks 5 are provided at both ends of the outer cylinder surface of the first inner cylinder 6 . The inner cylinder surface of the outer cylinder 4 is provided with friction balls 12 via supports 13 . The friction balls 12 are embedded in the spiral tracks 5 .

[0049] When the outer cylinder 4 and the first inner cylinder 6 generate relative motion along the axis, the first inner cylinder 6 can rotate around its own axis under the action of the spiral track 5 and the friction balls 12 .

[0050] The inner space of the partition 7 and the inner space of the spiral tube are filled with energy-consuming liquid. In this embodiment, the energy-consuming liquid is a magnetorheological fluid 39. Correspondingly, a coil 37 is wound around the outer surface of the first inner tube 6 between the two spiral tracks, and the coil 37 is connected to the power supply 23 through a current controller 42.

[0051] The piston 14 is large in the middle and small at both ends and the frustum 15 is arranged, so that the piston 14 can accelerate the energy-consuming liquid to flow toward the spiral tube 8 during the movement, thereby increasing the energy consumption effect.

[0052] A friction ring 11 is fixed to the outer side surface of the end wall of the first inner cylinder 6 close to the first end of the outer cylinder 4. The friction ring 11 is coaxially arranged with the first inner cylinder 6. The friction ring 11 contacts with a plurality of friction plates 10 distributed at equal intervals along the circumference. The friction plates 10 are elastically connected to the wall of the first end of the outer cylinder 4. Specifically, the friction plate 10 is fixedly connected to one end of a spring 17, and the other end of the spring 17 is fixedly connected to the wall of the first end of the outer cylinder 4. The spring 17 is made of shape memory alloy.

[0053] A second inner cylinder 16 is disposed below the first inner cylinder 6, and a set distance is provided between the second inner cylinder 16 and the first inner cylinder 6 to avoid hindering the movement of the first inner cylinder. A third inner cylinder 24 is disposed below the second inner cylinder 16, wherein the first inner cylinder 6, the second inner cylinder 16 and the third inner cylinder 24 are coaxially disposed and are all made of insulating material. The third inner cylinder 24 is fixedly connected to the cylinder wall of the second end portion of the outer cylinder 4, and the second inner cylinder 16 and the third inner cylinder 24 are fixedly connected.

[0054] like Figure 5 As shown, the piston rod 2 passes through the second inner cylinder 16 along the axial direction of the second inner cylinder 16, and the piston rod 2 is located inside the second inner cylinder 16 and is divided into a ball screw structure, including a screw 28, and the screw 28 is connected to the nut 26 through the ball 27. The screw 28, the ball 27 and the nut 26 together constitute a ball screw structure.

[0055] The end of the nut 26 close to the first inner tube is provided with an annular boss, which is embedded in a groove 25 provided on the wall of the end of the second inner tube 16 close to the first inner tube 6, so that the nut 26 can only rotate around its own axis and cannot move along the axis direction of the piston rod 2. The movement of the piston rod 2 along its own axis can make the nut 26 rotate around its own axis.

[0056] A groove plate 21 is provided at the middle position of the outer side surface of the nut 26. The groove plate 21 is sleeved on the outer periphery of the nut. The groove plate 21 is a conical structure as a whole, and the bottom surface is a plane. The conical surface is a concave surface that is concave away from the first inner cylinder.

[0057] A first permanent magnet 18 is fixed to the inner side of the end wall of the second inner cylinder 16 close to the first inner cylinder 6. The first permanent magnet 18 has an annular structure. A plurality of iron balls 20 are placed in the space between the groove plate 21 and the end wall of the second inner cylinder 16 close to the first inner cylinder 6. The first permanent magnet 18 can adsorb and fix the iron balls 20.

[0058] The outer side surface of the groove plate 21 and the inner cylinder surface of the second inner cylinder 16 are smaller than the diameter of the iron ball 20 so that the iron ball 20 will not fall from the space between the groove plate 21 and the second inner cylinder 16 .

[0059] Two baffles 19 are fixed to the outer surface of the nut 26 , and the two baffles 19 are arranged opposite to each other, that is, arranged at an interval of 180°. The baffles 19 are located below the first permanent magnet 18 . The baffles 19 rotate with the nut 26 and can knock down the iron ball 20 adsorbed on the first permanent magnet 18 .

[0060] like Figure 6 As shown, a stator shell 31 is fixed to the end wall of the second inner cylinder 16 away from the first inner cylinder 6 , and a stator core 30 is fixed in the stator shell 31 . The stator core 30 is sleeved on the outer periphery of the piston rod and fixed to the wall of the second inner cylinder 16 through the stator shell 31 .

[0061] A stator winding 38 is embedded in the stator core 30. Four second permanent magnets 29 arranged in an annular direction are provided in the space between the stator core 30 and the outer side surface of the nut 26. The second permanent magnets 29 are fixed to the outer side surface of the nut 26. The stator winding 38 is connected to the power supply 23 through the rectifier 22, wherein the power supply 23, the rectifier 22 and the current controller 42 are all installed inside the second inner cylinder 16.

[0062] An air spring 32 is arranged inside the third inner cylinder 24, the bottom of the air spring 32 is fixed to the buffer pad 36, the buffer pad 36 is fixed to the end wall of the third inner cylinder 24 away from the second inner cylinder 16, the piston rod 2 extends into the third inner cylinder 24, the end of the piston rod 2 is connected to the top of the air spring 32, and the connection position between the air spring 32 and the piston rod 2 is sealed.

[0063] A pressure detection element is provided between the air spring 32 and the buffer pad 36 . The pressure detection element is a pressure sensor 35 . The pressure sensor 35 is connected to the power source 23 and is powered by the power source 23 .

[0064] The inner side surface of the end wall of the third inner cylinder 24 away from the second inner cylinder 16 is also fixed with multiple additional air cavities 33 distributed at equal intervals along the annular direction. The top of the additional air cavity 33 is connected to one end of the pipeline, and the other end of the pipeline is connected to the bottom of the air spring 32.

[0065] The additional air cavity 33 is provided with a third permanent magnet 43 and a fourth permanent magnet 34 . The third permanent magnet 43 and the fourth permanent magnet 34 are arranged with the same poles facing each other so that a repulsive force can be generated between the third permanent magnet 43 and the fourth permanent magnet 34 .

[0066] The inner surface of the additional air cavity 33 is coated with lubricating oil, and the outer peripheral surfaces of the third permanent magnet 43 and the fourth permanent magnet 34 are in sealing contact with the inner surface of the additional air cavity 33, and the lubricating oil plays a role in sealing and reducing the sliding resistance of the fourth permanent magnet 34.

[0067] The third permanent magnet 43 is fixed at the bottom of the additional air cavity 33 , and a spring is arranged between the third permanent magnet 43 and the fourth permanent magnet 34 , and the spring is made of shape memory alloy material.

[0068] In this embodiment, the outer cylinder 4, the first inner cylinder 6, the second inner cylinder 16 and the third inner cylinder 24 are all made of insulating materials. A first hanging ring 1 is provided at the end of the piston rod 2 passing through the cylinder wall of the first end portion of the outer cylinder 4. A second hanging ring 41 is fixed to the cylinder wall of the second end portion of the outer cylinder 4 through a connecting plate 40, and is connected to the insulator string of the transmission line 44 through the first hanging ring 1 and the second hanging ring 41.

[0069] The working principle of the energy-consuming anti-dancing device of this embodiment is:

[0070] like Fig. 9 As shown, the two hanging rings 1 at the second end of the piston rod 2 and the outer tube 4 are respectively connected to the insulator strings of the two-phase conductors. When the conductors dance, the insulator strings will drive the insulator strings to vibrate against each other, and the insulator strings will drive the piston rod 2 to vibrate up and down along its own axis in the outer tube 4.

[0071] The first inner cylinder 6, the piston 14, the magnetorheological fluid 39, the spiral tube 8 and other components form an inertia system. On the one hand, the piston rod 2 drives the piston 14 in the first inner cylinder 6 to move up and down inside the first inner cylinder 6, squeezing the magnetorheological fluid 39 in the internal space of the partition 7. The magnetorheological fluid 39 will flow into the spiral tube 8 to generate flow, and the energy of the wire vibration is dissipated through the viscosity of the magnetorheological fluid 39 in the spiral tube 8. On the other hand, since the diameter of the first inner cylinder 6 is much larger than the inner diameter of the spiral tube 8, the flow rate of the magnetorheological fluid 39 in the spiral tube 8 is accelerated, thereby forming a hydraulic inertia system to achieve the purpose of efficiently dissipating energy and reducing vibration. At the same time, the piston 14 is large in the middle and small at both ends, and the structure of the frustum 15 makes the magnetorheological fluid 39 tend to be squeezed outward when the piston 14 moves up and down, and the liquid pressure at the inlet and outlet of the spiral tube 8 increases, further enhancing the inertia dissipation effect.

[0072] Under the thrust of the piston 14, the first inner cylinder 6 tends to move along the axis of the piston rod 2. At this time, under the action of the friction ball 12 and the spiral track 5, the first inner cylinder 6 moves along the axis of the piston rod 2 while rotating around its own axis. Since the friction plate 10 is always in contact with the friction ring 11 under the action of the spring 17, the friction plate 10 and the friction ring 11 move relative to each other, generating friction, realizing friction energy consumption, and accelerating energy consumption and vibration reduction.

[0073] Inside the second inner cylinder 16, the iron ball 20 is adsorbed and fixed on the first permanent magnet 18 under the action of the first permanent magnet 18. Since the piston rod 2 is a ball screw structure in the second inner cylinder 16, according to the principle of the ball screw, the nut 26 rotates around its own axis driven by the ball 27. The nut 27 drives the baffle 19 to rotate. When the baffle 19 passes under the first permanent magnet 18, it collides with the iron ball 20 adsorbed on the first permanent magnet 18, knocking the iron ball 20 off, realizing multiple collision energy consumption between the iron ball 20 and the iron ball 20, and between the iron ball 20 and the baffle 19.

[0074] At the same time, the nut 26 drives the second permanent magnet 29 at its bottom to rotate, and then generates a cutting magnetic field with the annular coil of the stator winding 38 to form an electric current, which is then stored in the power supply 23 through the rectifier 22. On the one hand, it realizes energy self-supply, and on the other hand, it converts the rotational energy into electrical energy.

[0075] like Figure 7 As shown, since the up and down movement of the piston rod 2 can generate a force on the air spring 32, the pressure value change detected by the pressure sensor 35 is further fed back to the current controller 42, and the current controller 42 then adjusts the power supply current of the power supply 23 to the outer peripheral coil 37 of the first inner cylinder 6, thereby adjusting the magnetic flux. The viscosity of the magnetorheological fluid 39 will change due to the change of the magnetic field, and then the shock absorbing effect of the entire device can be autonomously adjusted by the amplitude of the vibration.

[0076] When the vibration ends, the spring 17 between the friction plate 10 and the outer cylinder 4 returns to its original state, and the air spring 32 returns to its original state with unchanged stiffness, thereby ensuring that the device works normally during the next vibration reduction.

[0077] When the piston rod 2 squeezes the air spring 32, the third permanent magnet 43 and the fourth permanent magnet 34 in the additional air cavity 33 will approach each other. Due to the mutual repulsion of magnetism, the third permanent magnet 43 and the fourth permanent magnet 34 will promote the air spring 32 to return to its original state, accelerate the recovery speed, and thus improve the energy consumption efficiency of the entire device.

[0078] The device of this embodiment utilizes the inertia effect of the high-speed flow of liquid from the large-section first inner tube 6 to the thin spiral tube 8 to achieve the purpose of amplifying liquid damping and efficient energy consumption; the vertical vibration of the piston rod 2 is converted into the horizontal rotation of the nut 26 through the ball screw, and then the horizontal rotational motion is converted into various forms of collision of the iron ball 20 and electrical energy, thereby achieving multiple energy consumption and energy self-sufficiency; the instantaneous rheological properties of the magnetorheological fluid 39 are utilized in combination with the current controller 42 to achieve autonomous adjustment; the characteristics of the air spring 32 and the memory alloy spring are utilized to achieve self-recovery of the device.

[0079] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
