Description
Technical Field
The utility model relates to the technical field of new energy, in particular to a frequency-adjustable ultralow-frequency multidirectional shaking power generation device.
Background
In order to meet the energy demand of human beings, a large amount of fossil fuels, such as petroleum, coal and the like, are burned. This process produces large amounts of carbon dioxide and other room gases, which exacerbates global climate warming and threatens human survival. Therefore, development of clean energy and improvement of energy utilization efficiency are necessary. The mature clean energy sources of the current development technology mainly comprise nuclear energy, solar energy, wind energy, water energy, mechanical vibration energy and the like; mechanical vibration energy such as periodic vibration during running of a rotary machine, swing arm motion during walking of a person, and the like has difficulty in large-scale development due to small scale of the mechanical vibration energy. But the mechanical vibration is not influenced by factors such as climate environment, and the like, is very common in human life, has lower difficulty in capturing technology, and has wide prospect in solving the power supply problem of the distributed Internet of things equipment.
Mechanical vibration can be roughly classified into low-frequency vibration and high-frequency vibration according to frequency characteristics. The low frequency vibration is more challenging due to the smaller power than the high frequency vibration, and the corresponding energy harvesting. The energy conversion principle applicable to vibration energy collection at present mainly comprises an electromagnetic induction law, a piezoelectric effect, electrostatic induction, a friction electrification effect, a magnetostriction effect and the like; the vibration power generation device based on the electromagnetic induction principle is generally composed of a coil and a magnet, and compared with the vibration power generation device designed based on other principles, the electromagnetic vibration power generation device has stronger environmental adaptability due to no need of advanced materials and complex structures, so that the electromagnetic vibration power generation device has potential in popularization and application.
The existing vibration power generation devices can be roughly divided into two types according to a driving principle, namely an inertial force driving type and a displacement driving type; the inertial force driving type is to drive the mass block by using the inertial force born by the mass block in the vibration process to generate relative motion with the coil, so that the mechanical energy is converted into electric energy through the law of electromagnetic induction.
The common structural forms of the inertial force driving type vibration power generation device are a spring-vibrator structure, a cantilever beam structure and a pendulum-shaped structure, and the spring-vibrator structure is most common: if the patent CN109600013B is granted, the magnetic force is utilized to restrain the vibrating magnet, so that a spring-vibrator structure is formed, and vibration energy collection is realized; as the patent CN105720860B, a device for collecting the vibration energy of the steel rail by utilizing the piezoelectric cantilever beam is proposed; an electromagnetic wave energy collecting device of pendulum-like structure is proposed as the patented patent CN 105888955B.
The inertial force driven vibration power generation device does not need a complex transmission device, so the device has certain advantages in the aspect of miniaturization; the displacement driving type is to drive the transmission device by utilizing displacement generated in the vibration process of the object, so that the linear vibration of the vibrator is converted into rotary motion, and the driving motor converts mechanical energy into electric energy. Patent 206592471U of the issued patent sets forth a vibration energy feedback shock absorber for an automobile. The device can convert the linear vibration of the suspension system into the rotary motion of the motor, and can convert the vibration mechanical energy generated during the running of the automobile into electric energy;
environmental vibration is usually time-varying, and vibration in different environments has a significant difference in frequency characteristics, but most of existing vibration power generation devices cannot adjust their own frequency response characteristics to adapt to different environmental vibrations; the inertial force driven vibration power generation device generally needs mechanical connection mechanisms to restrict the displacement of the vibrator, and the mechanical connection mechanisms need to bear the impact action of the vibrator in the reciprocating motion process, so that the vibration power generation device is a weak link of the whole system; displacement driven vibration power generation devices utilize complex transmissions to convert linear vibrations into rotational vibrations, and this structural complexity often makes it difficult for him to collect vibration energy in multiple directions.
