Description
Technical Field
The invention relates to the technical field of wave energy collection, in particular to a vertical pendulum frequency-raising type wave energy collecting device and carrying equipment.
Background
Wave energy refers to the kinetic and potential energy of waves on the ocean surface. The energy resources of ocean waves are rich, and the development and utilization of the wave energy have a large application space for the endurance of ocean equipment. Wave energy collection is currently mainly of two types: one is that the energy collecting device is directly contacted with the seawater, and the energy conversion device is directly driven by the moving seawater; the other type is that the energy collecting device is integrated in the carrying platform, and the wave energy is indirectly collected by collecting the vibration energy generated by the platform under the action of waves. Human beings have relatively studied energy collecting devices driven by seawater direct contact, such as direct mechanical transmission, low-pressure hydraulic transmission, high-pressure hydraulic transmission, pneumatic transmission and the like, but most of the devices are distributed in coastal or offshore areas, and the devices have huge volumes. The device for indirectly collecting wave energy is developed later, and has the advantages of small volume, easy integration and the like. In order to monitor the marine environment and develop marine resources, the device for indirectly collecting wave energy is integrated in an offshore observation platform, such as an ocean buoy, an offshore vehicle and the like, so that energy collection can be carried out in non-coastal and offshore areas, power is supplied to sensors in equipment platforms, the service life of the equipment is prolonged, and the device has important significance for marine monitoring and development.
At present, there are relatively few devices for indirect collection of wave energy, or wave energy collection devices arranged directly above and below sea level, which can be integrated in equipment platforms at sea as well as in the sea. The existing device generally adopts a form of combining an energy harvesting structure with several power generation types such as electromagnetic power generation, piezoelectric power generation or friction power generation. The electromagnetic power generation type generally adopts a spring vibrator structure and a gear speed-increasing and frequency-increasing mechanism. The carrying platform moves under the action of sea waves and drives the mass block fixed at the movable end of the spring to generate forced vibration, and then the gear set drives the magnet or the metal coil to rotate, so that the induction metal coil on the energy collector generates induced potential and outputs electric energy. The electromagnetic power generation energy collecting device has the characteristics of extremely low frequency and complex vibration waveform in space due to ocean wave vibration, the vibration frequency of the electromagnetic power generation energy collecting device is extremely low, the energy loss is large in the frequency increasing operation process of the gear set, the change rate of the magnetic flux of the metal coil is small, and the power generation output power is not high. The piezoelectric power generation type generally adopts a cantilever beam structure with a mass block attached to the tail end, and the mass block drives the cantilever beam to vibrate spontaneously under the action of sea waves and inertia, so that the cantilever beam made of piezoelectric materials generates positive and negative deflection changes, a piezoelectric effect is generated, and energy output is generated. Because the cantilever beam natural frequency is higher, the coincidence degree with the ocean wave vibration frequency is low, and on the premise that the front end has no relevant frequency raising mechanism, the ocean environment adaptability of the collecting device is poor, and the requirement is difficult to meet. The friction type power generation is a type in which the surfaces of two materials are in contact with and separated from each other, and electric energy output is realized according to the coupling of triboelectric generation and electrostatic induction. Generally, under the action of external force generated by wave vibration, the surfaces of two different materials are contacted and separated by a certain mode, such as mutual impact friction of freely rolling balls on a plane, and the like, so that electric energy is generated and output. And the frequency of the wave vibration in the sea is low, and the vibration waveform in the space is complex, so that the frequency of the contact and separation of the surfaces of the friction materials is low, the rigid bodies collide with each other to greatly lose energy, the service life of the friction materials is shortened, and the output electric energy is low and the service life is short.

The preferred embodiment of the present invention further discloses a carrying device, which carries the pendulous pendulum frequency-raising wave energy collecting device 1 according to any of the above embodiments, and optionally, the carrying device is a buoy 40, an aircraft, or other devices, referring to fig. 5.
When the carrying equipment is static, the mass pendulum 21 is subjected to gravity and supporting force of the main shaft 23, the two parts of torque balance guarantee devices are in a static state, the carrying equipment drives the device to fluctuate and rock under the fluctuation excitation of sea waves, the mass pendulum 21 and the shell generate relative motion under the action of inertia, and the energy harvesting system 2 fluctuates along with the motion of the carrying equipment, so that potential energy exists. Meanwhile, the moment generated in the vertical direction of gravity and the moment generated by the supporting force of the main shaft 23 do not offset, so that the energy capturing system 2 generates reciprocating rotation motion. Under the influence of the interaction between the magnets, assuming that when the pendulum mass 21 swings to one side, the energy capturing magnets 22 in the energy capturing system 2 exhibit attractive force to the energy capturing magnets 34 in the electromagnetic energy converting system 3, when the pendulum mass 21 swings rapidly through the center, the energy capturing magnets 34 originally affected by the attractive force rapidly receive repulsive force due to the change of the polarity of the energy capturing magnets 22, and then the rotating support 32 fixed relative to the energy capturing magnets 34 is turned at high speed and obtains kinetic energy. The pendulum mass 21 is subjected to inertia when it is swung to one side, and when it changes direction, it decreases in speed and makes a short stop on one side, at which time the transducer magnet 34 is always attracted by the energy-capturing magnet 22. Since the transducer magnet 34 has kinetic energy and is in a rotating state, the rotating bracket 32 generates high-frequency reciprocating rotation motion under the influence of attraction force. The metal coil 33 cuts the magnetic induction lines when the transduction magnet 34 reciprocates at high frequency to generate high electric energy output, so that the device realizes the conversion from low-frequency wave excitation to high-frequency alternating current, and can regulate and rectify the electric energy into a waveform matched with a load for output through power management.
In some embodiments, a stroke spring 4 which cooperates with the mass pendulum 21 to limit the swing angle of the mass pendulum 21 is further arranged in the housing. Specifically, one end of the stroke spring 4 is connected to the housing, and the other end is a free end for abutting against the mass pendulum 21. Further, the length of the stroke spring 4 is adjustable, and the maximum swing angle of the mass pendulum 21 is adjusted by adjusting the length of the stroke spring 4. The maximum inclination angle required by equipment carrying when the mass pendulum 21 crosses the potential energy maximum point can also be influenced by adjusting the number of the energy capturing magnets 22 and the energy conversion magnets 34 and changing the mutual stress between the magnets. Therefore, the natural frequency close to or even the same as the applied sea wave motion frequency is adjusted, so that the excitation of the waves in the sea area can be actively responded when the whole device works, the mass pendulum 21 easily crosses the potential trap, and the purposes of efficiently collecting and transmitting energy and realizing the optimization of electric energy output are achieved in a non-contact excitation frequency-increasing mode.
