Description

Technical Field

[0001] The present invention relates to the field of new energy and construction engineering technology, and in particular to a high-efficiency new energy vibration controller integrating passive, semi-active and active control. Background Art

[0002] Vibration control dampers are categorized as active, semi-active, and passive vibration controllers, each with its own advantages and disadvantages. For example, active vibration controllers offer excellent control effects, but they require high precision in modeling the controlled object. The accuracy of the controlled object's parameters (such as mass, stiffness, and damping) directly impacts the control effect and the magnitude of the control parameters (e.g., the stroke and velocity of the inertial mass and the power of the actuator). Semi-active vibration controllers, while requiring relatively low external energy input, offer poor control effects. Passive vibration controllers, while not requiring external energy input, can only control a certain mode of the controlled object and are highly frequency-sensitive.

[0003] Although vibration controllers combining active and passive control have been proposed, traditional active vibration controllers require external energy input. In extreme situations, such as earthquakes and typhoons, power outages can cause traditional vibration controllers to fail. Furthermore, traditional passive vibration controllers are highly sensitive to frequency, occupy a large space, have complex structures, and suffer from poor reliability. Furthermore, traditional vibration controllers cannot generate electricity through multiple channels, resulting in poor efficiency in converting new energy into electricity. Summary of the Invention

[0018] (3) Beneficial effects

[0019] The beneficial effects of the present invention are:

[0020] The present invention provides a high-efficiency new energy vibration controller that integrates passive, semi-active, and active control. Due to the provision of a battery assembly, a wound magnetic device, and an inertial mass assembly, when the inertial mass assembly is subjected to a small external load in response to a controlled object, the electromagnetic wires of the wound magnetic device and the magnetic coils of the magnetic housing are both de-energized, causing the inertial mass assembly to swing, thereby driving the magnetic housing at the bottom of the inertial mass assembly to swing, i.e., passive control. When the magnetic coils in the magnetic housing are energized and the electromagnetic wires of the wound magnetic device are de-energized, the damping parameters can be dynamically adjusted by changing the magnetic field strength in the magnetic housing, i.e., semi-active control. When the external load is rare, the magnetic coils of the magnetic housing and the electromagnetic wires of the wound magnetic device are energized, i.e., active control. The wound magnetic device drives the magnetic housing to cause the inertial mass assembly connected thereto to perform reciprocating motion, i.e., active control. To ensure reliability when the external power supply is cut off under overload conditions, the working state switching mode can be set to: "active-semi-active-passive" switching mode. After the power supply is supplied to the active control mode for a period of time, due to power consumption, when the battery power is reduced to a certain level, it switches to the semi-active control mode. When the power is completely consumed, it automatically switches to the passive control mode.

[0021] In passive control mode, the magnetic field within the magnetic housing and the electromagnetic wire in the wound magnetic device produce relative displacement. This magnetic field cuts the electromagnetic wire, generating electrical energy that is stored in the battery pack via the wound magnetic device. Furthermore, when the electromagnetic wire is cut, a certain resistance is generated to suppress the oscillation of the inertial mass assembly. If the external power source is unavailable, the battery pack can power the electromagnetic wire of the wound magnetic device and the magnetic coil of the magnetic housing, improving the reliability of the high-efficiency vibration controller.

[0022] The inclusion of a damping piezoelectric device not only provides damping but also converts the energy of the external excitation load acting on the controlled object into electrical energy, thereby increasing the utilization rate of new energy. This high-efficiency vibration controller boasts strong vibration suppression capabilities, high reliability, high energy utilization, and a wide range of applications.

[0038] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] like Figure 1-2 As shown, an embodiment of the present invention provides a high-efficiency new energy vibration controller that integrates passive, semi-active, and active control, including a multi-cavity beam 1, a battery assembly 2, a wound magnetic device 3, a damping piezoelectric device 4, an inertial mass assembly 5, a magnetic box 8, and a pendulum length adjustment device 7. The wound magnetic device 3 and the damping piezoelectric device 4 are both connected to an external power supply.

[0040] like Figure 1-2 As shown, the battery assembly 2 is mounted within a multi-cavity beam 1. Both ends of the multi-cavity beam 1 are connected to the controlled object. The bottom of the multi-cavity beam 1 is connected to the inertial mass assembly 5 via a steel wire rope 6. A magnetic box 8 is positioned at the bottom end of the inertial mass assembly 5. The multi-cavity beam 1 is constructed from an I-beam with a hole cut into it. The steel wire rope 6 connects to the multi-cavity beam 1 through the hole. The size and shape of the hole are designed based on the actual load conditions. The multi-cavity beam 1 can be connected to a shear wall or other controlled object via bolts or embedded components. The controlled object can be a building component, a tall wind turbine component, an offshore wind turbine component, or other components requiring vibration control. The steel wire rope 6 can consist of a single or multiple wire ropes 6. The diameter and strength of the wire rope 6 are determined by the specific load conditions and design.

[0041] like Figure 3 As shown, the winding magnetic device 3 includes a connecting rod 31, a plurality of winding rods 33, and an electromagnetic wire 32 wound on the winding rods 33. The winding rods 33 are arranged crosswise, and the center of the intersection coincides with the axis of the connecting rod 31. The top end of the connecting rod 31 is fixedly connected to the bottom of the multi-cavity beam 1, and the bottom end of the connecting rod 31 passes through the central through hole 51 on the inertial mass assembly 5 and is arranged in the magnetic box 8. The magnetic box 8 has a magnetic field and is provided with a magnetic ring 83 for changing the magnitude of the magnetic field. The connecting rod 31 and the winding rod 33 are integrally formed and can be processed from high-strength steel.

[0042] like Figure 2 As shown, the damping piezoelectric device 4 is mounted on the outer wall of the connecting rod 31. The damping piezoelectric device 4 and the wound magnetic device 3 are both electrically connected to the battery assembly 2. Of course, in actual use, the new energy vibration controller also includes a control device that can adjust the current input from the battery assembly 2 into the wound magnetic device 3 to adjust the motion amplitude of the inertial mass assembly 5. The battery assembly 2 includes multiple battery cells, which are connected in series. The multi-cavity beam 1 defines multiple cavities, and a battery cell is sequentially placed in each cavity.

[0043] In practice, for ease of processing and installation, the inertial mass assembly 5 comprises multiple stacked masses. These masses are bolted together, allowing adjacent masses to be detachably connected. This facilitates adjusting the weight of the inertial mass according to actual conditions, thereby achieving the desired control effect. Each mass has an opening at its center. The openings formed by the connection of the multiple masses form a central through-hole 51. The dimensions of central through-hole 51 are determined by the travel of the mass. In this embodiment, it is square, but other shapes are also possible.

[0044] like Figure 5 As shown, the magnetic housing 8 includes a magnetic housing body 81 and multiple pairs of magnetic bodies 82. Each magnetic coil 83 is disposed on each magnetic body 81. By changing the magnitude of the current flowing through the magnetic coil 83, the magnetic field strength within the magnetic housing 8 can be changed, thereby dynamically adjusting the damping parameters. Each pair of magnetic bodies 82 has opposite magnetic properties. The top of the magnetic housing 8 is connected to the bottom of the inertial mass assembly 5. The magnetic housing 8 defines a receiving cavity. Each pair of magnetic bodies 82 is disposed oppositely on the side walls of the magnetic housing body 81 to generate a magnetic field within the receiving cavity. The winding rod 33 on the connecting rod 31 extends through the central through-hole 51 into the receiving cavity, and each pair of magnetic bodies 82 is disposed at each end of the winding rod 33. In this embodiment, the winding magnetic device 3 includes two winding rods 33, which are integrally formed with the bottom end of the connecting rod 31. The magnetic housing body 81 is a rectangular structure, and two pairs of magnetic bodies 82 are disposed oppositely within the receiving cavity.

[0045] In actual application, the magnetic box 8 also includes multiple magnetic rings 83, and each magnetic body 82 is provided with a magnetic ring 83, which can adjust the magnetic field intensity distribution, thereby dynamically adjusting the damping size to better control the swing of the inertial mass component 5.

[0046] like Figure 4As shown, the damping piezoelectric device 4 is a rotating body structure. It includes a sleeved piezoelectric ceramic inner cylinder 41 and a damping rubber outer cylinder 42. The inner wall of the damping rubber outer cylinder 42 is bonded to the outer wall of the damping rubber outer cylinder 42, and the two are connected by bonding. The piezoelectric ceramic inner cylinder 41 is sleeved on the connecting rod 31, and the inner wall of the piezoelectric ceramic inner cylinder 41 is bonded to the outer wall of the connecting rod 31. A power line is connected to the piezoelectric ceramic inner cylinder 41, and the other end of the power line is connected to the battery unit. While providing damping, the damping piezoelectric device 4 can also convert the energy of the external excitation load acting on the controlled object into electrical energy, which is stored in the battery assembly 2 to provide power for the active control mode. The damping rubber outer cylinder 42 in the damping piezoelectric device 4 limits the travel of the inertial mass assembly 5, preventing the inertial mass assembly 5 from colliding with the controlled object, thereby ensuring the safe operation of the high-efficiency new energy vibration controller and improving its reliability.

[0047] In this embodiment, since the damping piezoelectric device 4 and the wound magnetic device 3 can both convert other forms of energy into electrical energy and store it in the battery assembly 2, in addition to powering the new energy vibration controller, they can also power other electrical appliances, thereby improving the reliability of the new energy vibration controller while effectively utilizing energy.

[0048] like Figure 6 As shown, the pendulum length adjustment device 7 can effectively control the pendulum length of the wire rope 6 and thus adjust the swing period of the new energy vibration controller. The pendulum length adjustment device 7 includes a sleeved inner guide cylinder 71 and an outer slide cylinder 72. The top end of the inner guide cylinder 71 is fixedly connected to the bottom end of the multi-cavity beam 1. The inner guide cylinder 71 and the outer slide cylinder 72 are slidably connected. The wire rope 6 passes through the outer slide cylinder 72 and is connected to the bottom end of the inertial mass assembly 5. The outer slide cylinder 72 slides along the inner guide cylinder 71 to adjust the pendulum length of the wire rope 6.

[0049] Specifically, a plurality of first adjustment hole groups are provided on the circumference of the inner guide cylinder 71, and the plurality of first adjustment hole groups are arranged with the axis of the inner guide cylinder 71 as the center, and each first adjustment hole group includes a plurality of first adjustment holes 711 arranged at equal intervals in the vertical direction, and the outer slide cylinder 72 includes a connected fixing portion 721 and a connecting portion 722, and the wire rope 6 passes through the connecting portion 722, and a plurality of second adjustment hole groups are provided on the circumference of the fixing portion 721, and the plurality of second adjustment hole groups are arranged with the axis of the outer slide cylinder 72 as the center, and the second adjustment hole group includes a plurality of second adjustment holes 7211 arranged at equal intervals in the vertical direction, and the fixing portion 721 slides along the inner guide cylinder 71, and bolts pass through the first adjustment holes 711 and the second adjustment holes 7211 to connect the inner guide cylinder 71 and the outer slide cylinder 72. The first adjustment hole 711 and the second adjustment hole 7211 are both threaded holes. By adjusting the outer slide cylinder 72 to slide up and down and then fixing it with bolts, the effective swing length of the wire rope 6 can be adjusted. The swing length of the wire rope 6 can be determined by calculating the control frequency of the controlled object.

[0050] When the effective pendulum length is not within the desired frequency range, a spring (not shown) is provided on the winding rod 33, one end of the spring is connected to the end of the winding rod 33, and the other end of the spring is connected to the magnetic body 82 to increase the stiffness of the high-efficiency new energy vibration controller so that the amplitude of the mass swing is within the expected frequency range.

[0051] When the controlled object is a structure or equipment with greater flexibility (such as a super high-rise building, a TV tower, and a wind turbine, etc.), since the period of the controlled object is too large and the required pendulum length is too long, the connection between the wire rope 6 and the multi-cavity beam 1 can be set to be slidable along the long axis direction of the multi-cavity beam 1 and the circular hole on the outer slide cylinder 72 can be set to a rectangular hole. At the same time, the stiffness of the spring (not shown) on the winding rod 33 can be set to a smaller value, which can greatly reduce the length of the wire rope 6, thereby significantly saving the vertical space occupied by the high-efficiency new energy vibration controller.

[0052] The present invention provides a high-efficiency new energy vibration controller that integrates passive, semi-active, and active control. Due to the provision of a battery assembly 2, a wound magnetic device 3, an inertial mass assembly 5, and a pendulum length adjustment device 7, when the inertial mass assembly 5 is subjected to a small external load under the response of the controlled object, the electromagnetic wire 32 of the wound magnetic device 3 and the magnetic ring 83 of the magnetic box 8 are both de-energized, the inertial mass assembly 5 swings, and thereby drives the magnetic box 8 at the bottom end of the inertial mass assembly 5 to swing, which is passive control. When the magnetic ring 83 in the magnetic box 8 is energized and the electromagnetic wire 32 of the wound magnetic device 3 is de-energized, the damping parameter can be dynamically adjusted by changing the magnetic field strength in the magnetic box 8, which is a semi-active control mode. When the external load is a rare working condition, the magnetic ring 83 of the magnetic box 8 and the electromagnetic wire 32 of the wound magnetic device 3 are energized, which is active control. The wound magnetic device 3 drives the magnetic box 8 to move, causing the inertial mass assembly 5 connected thereto to perform reciprocating motion, which is active control. To ensure reliability when the external power supply is cut off under overload conditions, the working state switching mode can be set to: "active-semi-active-passive" switching mode. After the power supply is supplied to the active control mode for a period of time, due to power consumption, when the battery power is reduced to a certain level, it switches to the semi-active control mode. When the power is completely consumed, it automatically switches to the passive control mode.

[0053] In passive control mode, the magnetic field within magnetic housing 8 and electromagnetic wire 32 of wound magnetic device 3 produce relative displacement. This magnetic field within magnetic housing 8 cuts electromagnetic wire 32, generating electrical energy. This energy is then stored in battery assembly 2 via wound magnetic device 3. Furthermore, when electromagnetic wire 32 is cut, a certain resistance is generated, suppressing the oscillation of inertial mass assembly 5. If an external power source is unavailable, battery assembly 2 can power electromagnetic wire 32 of wound magnetic device 3 and magnetic coil 83 of magnetic housing 8, improving the reliability of the high-efficiency vibration controller.

[0054] At the same time, due to the provision of the damping piezoelectric device 4, when the inertial mass component 5 collides with the damping piezoelectric device 4 on the wound magnetic device 3 due to excessive stroke, the damping piezoelectric device 4 can limit the stroke of the inertial mass component 5 to prevent the inertial mass component 5 from colliding with the controlled object, thereby improving the operational safety of the device. While providing damping, it can also convert the energy of the external excitation load acting on the controlled object into electrical energy. On the basis of the electrical energy generated by the wound magnetic device 3 cutting the magnetic field, the excess kinetic energy of the inertial mass component 5 is converted into electrical energy by impacting the piezoelectric ceramic inner cylinder 41, that is, multi-channel electrical energy generation, thereby improving the utilization rate of new energy.

[0055] Different working modes can be selected and combined according to different working conditions, so that the vibration control effect is significantly improved compared with the control effect of traditional vibration controllers. For example, when the external excitation is a rare typhoon or earthquake, the urban area where the controlled object is located is out of power or the power line of the controlled object is damaged, the active control mode with higher control efficiency can be selected first; when the battery assembly 2 has been working in the active control mode for a period of time, when the power of the battery assembly 2 cannot drive the inertial mass assembly 5 to move, it can be switched to the semi-active control mode; when the power of the battery assembly 2 is exhausted, it can be switched to the passive control mode that does not require the input of electric energy. This can ensure the ability of the controlled object to work normally under rare external excitation (especially the controlled objects that play an important role in society, such as important buildings such as TV signal towers, hospitals, primary and secondary schools, and nuclear power plants, as well as equipment that ensures lifelines), and significantly improve the control effect of the high-efficiency new energy vibration controller.

[0056] When multiple high-efficiency new energy vibration controllers integrating passive, semi-active and active control are arranged vertically and horizontally along the controlled object, and different effective pendulum lengths are set to control each mode of the controlled object respectively, the cost of a single new energy vibration controller and the difficulty of manufacturing its components can be significantly reduced. At the same time, the disadvantage of traditional passive vibration controllers being sensitive to modal period can be avoided, and the vibration control effect under the passive control mode can be improved.

[0057] In summary, this high-efficiency new energy vibration controller can generate electrical energy in multiple channels, has a high new energy conversion rate, and has the characteristics of strong vibration suppression ability, strong reliability, high operational safety and a wide range of applications.
