Description

一种垂摆升频式波浪能收集装置及搭载设备A vertical pendulum up-frequency wave energy collection device and its carrying equipment 技术领域technical field
本发明涉及波浪能收集技术领域，特别涉及一种垂摆升频式波浪能收集装置及搭载设备。The invention relates to the technical field of wave energy collection, in particular to a pendulum up-frequency wave energy collection device and carrying equipment.
背景技术Background technique
波浪能是指海洋表面波浪所具有的动能和势能。海洋波浪的能量资源丰富，发掘利用波浪能为海洋装备续航有很大的应用空间。波浪能收集目前主要有两种类型：一种是能量收集装置直接与海水接触，通过运动的海水直接驱动能量转换装置；另一种是能量收集装置集成搭载平台内部，通过收集平台受到波浪作用产生的振动能量，间接收集波浪能。人类对于海水直接接触驱动的能量收集装置的研究相对较多，如直接机械传动、低压水力传动、高压液压传动、气动传动等，但是大多都分布于沿海或近海地区，且装置体积巨大。间接收集波浪能的装置发展较晚，具有体积小、易于集成等优点。为了监测海洋环境和开发海洋资源，将间接收集波浪能的装置集成于海上观测平台，如海洋浮标、海上航行器等，可在非沿海近海地区进行能源收集，为这些设备平台中的传感器供电并延长设备的使用周期，对海洋的监测和开发具有重要意义。Wave energy refers to the kinetic and potential energy of ocean surface waves. The energy resources of ocean waves are abundant, and there is a great application space for exploring and utilizing wave energy for the battery life of marine equipment. There are currently two main types of wave energy harvesting: one is that the energy harvesting device is directly in contact with seawater, and the energy conversion device is directly driven by the moving sea water; vibration energy, and indirectly collect wave energy. There are relatively many studies on energy harvesting devices driven by direct contact with seawater, such as direct mechanical transmission, low-pressure hydraulic transmission, high-pressure hydraulic transmission, pneumatic transmission, etc., but most of them are distributed in coastal or offshore areas, and the devices are huge. The device for indirect wave energy harvesting was developed late, and has the advantages of small size and easy integration. In order to monitor the marine environment and develop marine resources, devices that indirectly collect wave energy are integrated into offshore observation platforms, such as ocean buoys, marine vehicles, etc., which can collect energy in non-coastal and offshore areas, and provide power for sensors in these equipment platforms. Extending the service life of equipment is of great significance to the monitoring and development of the ocean.
目前，可集成在海上以及海中的设备平台内间接收集波浪能的装置或直接布置在海平面上下的波浪能收集装置相对较少。现有装置一般采用俘能结构与电磁发电、压电发电或摩擦发电等几种发电类型相结合的形式。电磁发电类型一般采用弹簧振子结构，以及齿轮增速升频机构。搭载平台在海浪作用下运动并带动固定在弹簧活动端的质量块产生受迫振动，进而由齿轮组驱动磁体或金属线圈转动，使能量收集器上的感应金属线圈产生感生电势并输出电能。由于海洋波浪振动具有频率极低、空间中振动波形复杂的特点，这种电磁发电能量收集装置的振动频率极低，齿轮组升频操作过程中能量损失较大，金属线圈磁通量的变化率小，发电输出功率不高。压电发电类型一般采用末端附带质量块的悬臂梁结构，在海浪作用以及惯性作用下由质量块带动自发振动，从而使压 电材料的悬臂梁产生正负挠度变化，从而发生压电效应，产生能量输出。由于悬臂梁固有频率较高，与海洋波浪振动频率契合程度低、在前端没有相关升频机制的前提下，这种收集装置的海洋环境适应性差，难以满足需求。摩擦式发电类型是通过两种材料的表面相互接触和分离，根据摩擦生电和静电感应的耦合来实现电能输出。一般是在波浪振动产生的外力作用下，通过某种方式，如在平面上自由滚动小球相互撞击摩擦等，使两种不同的材料表面产生接触和分离，产生电能并输出。同样由于海洋中的波浪振动的频率较低、空间中振动波形复杂的原因，使得摩擦材料表面的接触和分离的频率较低，且相互间刚体撞击极大损失能量，摩擦使之寿命缩短，所以输出的电能较低使用寿命不长。At present, there are relatively few wave energy harvesting devices that can be integrated in equipment platforms on the sea and in the sea to indirectly collect wave energy or directly arranged above and below the sea level. Existing devices generally adopt the form of combining energy harvesting structure with 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-up and frequency-up 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 metal coil to rotate, so that the induction metal coil on the energy harvester generates an induced potential and outputs electric energy. Because ocean wave vibration has the characteristics of extremely low frequency and complex vibration waveform in space, the vibration frequency of this electromagnetic power generation energy harvesting device is extremely low, the energy loss is relatively large during the gear set up-frequency operation process, and the change rate of the magnetic flux of the metal coil is small. Generator output power is not high. The piezoelectric power generation type generally adopts a cantilever beam structure with a mass block at the end. Under the action of sea waves and inertia, the mass block drives spontaneous vibration, so that the cantilever beam of piezoelectric material produces positive and negative deflection changes, resulting in piezoelectric effect. energy output. Due to the high natural frequency of the cantilever beam, the low degree of fit with the vibration frequency of ocean waves, and the absence of a relevant up-frequency mechanism at the front end, this collection device has poor adaptability to the ocean environment and is difficult to meet the demand. The type of friction power generation is through the contact and separation of the surfaces of two materials, and the output of electric energy is realized according to the coupling of friction generation and electrostatic induction. Generally, under the action of external force generated by wave vibration, in some way, such as balls rolling freely on a plane, hitting and rubbing against each other, the surfaces of two different materials are contacted and separated, and electric energy is generated and output. Also due to the low frequency of wave vibration in the ocean and the complex vibration waveform in space, the contact and separation frequency of the friction material surface is low, and the collision of rigid bodies with each other greatly loses energy, and friction shortens its life. The output power is low and the service life is not long.

本发明优选实施例还公开了一种搭载设备，其搭载有上述任一实施例所述 的垂摆升频式波浪能收集装置1，可选的，所述搭载设备为浮标40、航行器等设备，参照图5。The preferred embodiment of the present invention also discloses a carrying device, which is equipped with the pendulum frequency-increasing wave energy collection device 1 described in any of the above embodiments. Optionally, the carrying device is a buoy 40, an aircraft, etc. equipment, refer to Figure 5.
当搭载设备静止时，质量摆21受到重力及主轴23的支持力，两部分扭矩平衡保证装置处于静止状态，在海浪波动激励下，搭载设备带动装置起伏晃动，质量摆21在惯性作用下与壳体产生相对运动，俘能系统2随着搭载设备的运动而发生起伏，从而存在势能。与此同时重力竖直方向上产生的力矩与主轴23的支持力产生的力矩不再相抵，从而俘能系统2产生往复式旋转运动。受磁铁之间的相互影响，假设当质量摆21摆动至一侧时，俘能系统2中的俘能磁铁22对电磁换能系统3中的换能磁铁34表现为吸引力，当质量摆21快速摆过中心时，原来受吸引力影响的换能磁铁34由于俘能磁铁22极性的改变迅速受到排斥力，于是与换能磁铁34相对固定的旋转支架32高速翻转并获得动能。质量摆21在摆动到一侧时会受惯性影响，在改变方向时速度降低并在一侧做短暂停留，此时换能磁铁34始终受到俘能磁铁22的吸引力。由于换能磁铁34本身已经具备动能并处于旋转状态，受吸引力影响，旋转支架32便会产生高频的往复旋转运动。金属线圈33切割换能磁铁34高频往复运动时的磁感应线，产生较高的电能输出，从而使装置实现低频波浪激励到高频交流电的转换，并可通过电源管理将电能稳压整流成匹配于负载的波形输出。When the equipped equipment is stationary, the mass pendulum 21 is supported by gravity and the main shaft 23, and the two parts of the torque balance guarantee device are in a static state. Under the excitation of the wave fluctuation, the driven device of the equipped equipment fluctuates and shakes, and the mass pendulum 21 is in contact with the shell under the action of inertia. The body produces relative motion, and the energy harvesting system 2 fluctuates with the movement of the equipment on board, so there is potential energy. At the same time, the torque generated in the vertical direction of gravity and the torque generated by the supporting force of the main shaft 23 no longer counteract, so that the energy harvesting system 2 generates a reciprocating rotational motion. Affected by the interaction between the magnets, it is assumed that when the mass pendulum 21 swings to one side, the energy capture magnet 22 in the energy capture system 2 behaves as an attraction force to the transducing magnet 34 in the electromagnetic transducing system 3, when the mass pendulum 21 When swinging through the center quickly, the transducing magnet 34 affected by the attractive force is quickly repelled due to the change of the polarity of the energy-capturing magnet 22, so the rotating bracket 32 relatively fixed with the transducing magnet 34 turns over at a high speed and obtains kinetic energy. The mass pendulum 21 will be affected by inertia when it swings to one side, and its speed will decrease and it will stay on one side for a short time when it changes direction. Since the transducing magnet 34 itself already has kinetic energy and is in a rotating state, affected by the attractive force, the rotating bracket 32 will generate high-frequency reciprocating rotational motion. The metal coil 33 cuts the magnetic induction line of the transducing magnet 34 during high-frequency reciprocating motion to generate higher power output, so that the device realizes the conversion from low-frequency wave excitation to high-frequency alternating current, and can stabilize and rectify the power into a matching power supply through power management. Waveform output on the load.
在一些实施例中，所述壳体内还设有与所述质量摆21配合限制质量摆21摆动角度的行程弹簧4。具体的，行程弹簧4的一端与壳体连接，另一端为用于与质量摆21抵接的自由端。进一步的，所述行程弹簧4的长度可调，通过调节所述行程弹簧4的长度调节所述质量摆21的最大摆动角度。也可以通过调整俘能磁铁22与换能磁铁34的数量，改变磁铁之间的相互受力大小，影响质量摆21越过势能最大点时搭载设备所需要的最大倾斜角度。从而调整出与应用海域波浪运动频率相近甚至相同的固有频率，使得在整个装置工作时能够积极响应该域波浪的激励，质量摆21轻松越过势陷，以非接触式激励升频的方式，达到高效收集并传递能量，实现电能输出的优化。In some embodiments, a travel spring 4 cooperating with the mass pendulum 21 to limit the swing angle of the mass pendulum 21 is also provided 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 travel spring 4 is adjustable, and the maximum swing angle of the mass pendulum 21 can be adjusted by adjusting the length of the travel spring 4 . It is also possible to change the mutual force between the magnets by adjusting the quantity of the energy-capturing magnet 22 and the energy-transforming magnet 34, so as to influence the maximum inclination angle required for carrying equipment when the mass pendulum 21 crosses the point of maximum potential energy. In this way, the natural frequency close to or even the same as the wave motion frequency in the application sea area can be adjusted, so that the whole device can actively respond to the excitation of the wave in this area when the whole device is working, and the mass pendulum 21 can easily overcome the potential trap, and achieve Efficiently collect and transfer energy to optimize power output.
本发明垂摆升频式波浪能收集装置能够收集多自由度运动超低频波浪能，采用磁铁之间互相激励的方法，实现了波浪低频激励情况下的非接触式升频，无需额外的传动系统，产生高频交流电压输出，实现波浪能的高效转换。区别于传统齿轮传动结构，该装置可有效避免齿轮接触而产生的磨损现象，有效提 高装置的使用寿命。The vertical pendulum up-frequency wave energy collection device of the present invention can collect multi-degree-of-freedom ultra-low-frequency wave energy, adopts the method of mutual excitation between magnets, and realizes the non-contact up-frequency under the condition of wave low-frequency excitation, without additional transmission system , generate high-frequency AC voltage output, and realize efficient conversion of wave energy.
