本发明涉及波浪能发电领域，具体涉及一种为水下航行器供电的隐蔽状态下波浪能发电装置。The invention relates to the field of wave energy power generation, and in particular to a concealed wave energy power generation device for providing power to underwater vehicles.
背景技术：Background technique:
我国海域面积约470万平方公里，海岸线长达18000多千米，岛屿众多，蕴藏着巨大的能源资源和经济资源。根据权威机构公布的数据，全球波浪能储量达约2.95万TWh/年(295亿千瓦时/年)，我国海域波浪能储量达约1000TWh/年(10亿千瓦时/年)，可开发的理论存储量为7000万千瓦左右。my country's sea area is about 4.7 million square kilometers, with a coastline of more than 18,000 kilometers and numerous islands, which contain huge energy and economic resources. According to data released by authoritative organizations, the global wave energy reserves amount to approximately 29,500 TWh/year (29.5 billion kilowatt hours/year), and the wave energy reserves in my country’s sea areas amount to approximately 1,000 TWh/year (1 billion kilowatt hours/year). The theory that it can be developed The storage capacity is about 70 million kilowatts.
经略海洋在政治和军事上具有举足轻重的战略意义。近年来围绕海洋开发、海洋资源调查、海洋渔业权益，国际上展开了新一轮的海洋竞争，蓝色疆土的保护和开发是以高科技为依托的经济竞争、科技竞争、军事竞争。随着我国近年来进一步提高了对海洋权益和海洋资源的重视程度，作为海洋巡视和监测的重要技术手段，水下无人航行器具有隐蔽、巡航距离长等优点，但同时水下无人航行器多依靠蓄电池为机载设备供电、甚至是提供驱动力。由于蓄电池的容量有限，会导致无人航行器作业半径、航行速度、机载设备探测器距离均受到限制，且无人航行器上浮至母船充电容易暴露目标。Managing the oceans is of strategic importance politically and militarily. In recent years, a new round of marine competition has launched internationally around marine development, marine resource surveys, and marine fishery rights and interests. The protection and development of blue territory is an economic competition, a technological competition, and a military competition based on high technology. As my country has further increased its emphasis on maritime rights and resources in recent years, as an important technical means for ocean patrol and monitoring, underwater unmanned vehicles have the advantages of concealment and long cruising distance, but at the same time, underwater unmanned navigation Aircraft mostly rely on batteries to power onboard equipment and even provide driving force. Due to the limited capacity of the battery, the operating radius, sailing speed, and airborne equipment detector distance of the unmanned vehicle will be limited, and the unmanned vehicle will easily expose the target when it floats to the mother ship for charging.
海洋中的波浪是由于风和地球引力作用产生的，在海洋表面以势能和动能的形式周期转换的机械能，但是波浪能不仅仅影响自由液面，还随着水深方向影响流场，如图1所示，当在1/2个波长水深内，波浪质点的能量依然可达自由液面的4％，而据计算在自由液面1/10波长内波浪质点的能量可达自由液面的54％，对于一个周期为6秒的深水规则波，其1/10波 长接近2.8米，也就是说在自由液面以下3米以内依然有将近50％左右的波浪能可以开发，这从理论上证明水下波浪能装置的开发具有广阔的前景。Waves in the ocean are generated by the action of wind and the earth's gravity. They are mechanical energy that is periodically converted in the form of potential energy and kinetic energy on the ocean surface. However, wave energy not only affects the free liquid surface, but also affects the flow field along the water depth direction, as shown in Figure 1. As shown, when the water depth is within 1/2 wavelength, the energy of the wave particles can still reach 4% of the free liquid surface, and it is calculated that the energy of the wave particles within 1/10 wavelength of the free liquid surface can reach 54% of the free liquid surface. %, for a deep water regular wave with a period of 6 seconds, its 1/10 wave The length is close to 2.8 meters, which means that nearly 50% of the wave energy can still be developed within 3 meters below the free liquid surface. This theoretically proves that the development of underwater wave energy devices has broad prospects.

其中，永磁电机3和蓄电池4均安装在浮力仓2内，永磁电机3和蓄电池4相连接，永 磁电机3包括定子31以及设置在定子31内的转子32，吸波浮体1通过连杆7和永磁电机3的转子32相连接，浮力仓2通过张力腿5和重力锚6相连接。Among them, the permanent magnet motor 3 and the battery 4 are installed in the buoyancy chamber 2, and the permanent magnet motor 3 and the battery 4 are connected. The magneto motor 3 includes a stator 31 and a rotor 32 arranged in the stator 31 . The wave-absorbing floating body 1 is connected to the rotor 32 of the permanent magnet motor 3 through a connecting rod 7 . The buoyancy chamber 2 is connected to the gravity anchor 6 through a tension leg 5 .
在波浪作用下，吸波浮体1由于在水下，其失去了自由面由于波浪升沉引起的垂向静水回复力，导致其在垂向受力大幅减小，且由于锚泊系统限制，那么依靠垂向运动做功难以俘获波浪能，因此本发明利用吸波浮体在波浪作用下的纵摇运动做功。Under the action of waves, since the wave-absorbing buoy 1 is underwater, it loses the vertical hydrostatic restoring force of the free surface caused by wave heaving, resulting in a significant reduction in vertical stress. Moreover, due to the limitations of the mooring system, it relies on It is difficult to capture wave energy when performing vertical motion, so the present invention uses the pitching motion of the wave-absorbing floating body under the action of waves to perform work.
在入射波作用下，吸波浮体1沿入射波方向摇动，同时带动永磁电机3的转子32转动发电，并充进蓄电池4；其中，浮力仓2浮力始终垂直海平面向上，而重力锚6重力远大于浮力仓2浮力，使得张力腿5处于绷紧状态，这种状态是本发明的一个重要技术，当吸波浮体1驱动永磁电机3的转子32转动时会产生反作用力，其将导致浮力仓2也发生转动，而浮力仓2由于浮力大于其重力，其产生的力矩将克服永磁电机3的转子32作用力矩，保障浮力仓处于稳定平衡状态，促使吸波浮体1与永磁电机3的定子31发生相对转动，从而保障高效发电。Under the action of the incident wave, the wave-absorbing floating body 1 shakes in the direction of the incident wave, and at the same time drives the rotor 32 of the permanent magnet motor 3 to rotate to generate electricity and charge the battery 4; among them, the buoyancy of the buoyancy chamber 2 is always vertical to the sea level and upward, while the gravity anchor 6 The gravity is much greater than the buoyancy of the buoyancy chamber 2, causing the tension legs 5 to be in a tight state. This state is an important technology of the present invention. When the wave-absorbing floating body 1 drives the rotor 32 of the permanent magnet motor 3 to rotate, a reaction force will be generated, which will As a result, the buoyancy tank 2 also rotates, and since the buoyancy of the buoyancy tank 2 is greater than its gravity, the torque generated by it will overcome the torque of the rotor 32 of the permanent magnet motor 3, ensuring that the buoyancy tank is in a stable and balanced state, and promotes the connection between the wave-absorbing floating body 1 and the permanent magnet. The stator 31 of the motor 3 rotates relative to each other, thereby ensuring efficient power generation.
在一具体实施例中，上述的连杆7成字母“T”字装，连杆7的竖向部和吸波浮体1相连接，横向部的两端均和永磁电机3的转子32相连接。如此，即可以同时带动两永磁电机3进行发电，以提高发电的效率In a specific embodiment, the above-mentioned connecting rod 7 is shaped like the letter "T", the vertical part of the connecting rod 7 is connected to the wave-absorbing floating body 1 , and both ends of the horizontal part are in phase with the rotor 32 of the permanent magnet motor 3 connect. In this way, the two permanent magnet motors 3 can be driven to generate electricity at the same time to improve the efficiency of power generation.
此外，在连杆7和永磁电机3的转子32之间还连接有棘轮8，当波浪激励力促使吸波浮体1沿着波浪入射反方向运动时，吸波浮体1在棘轮8的作用下不驱动永磁电机3的转子运动，保障吸波浮体1在受纵摇力矩较小时刻能复位，准备下一次沿着入射波方向转动驱动永磁电机3的转子32做功。In addition, a ratchet 8 is also connected between the connecting rod 7 and the rotor 32 of the permanent magnet motor 3. When the wave excitation force urges the wave-absorbing floating body 1 to move in the opposite direction of wave incidence, the wave-absorbing floating body 1 moves under the action of the ratchet 8 The rotor movement of the permanent magnet motor 3 is not driven to ensure that the wave-absorbing floating body 1 can be reset when the pitching moment is small, and is ready to rotate along the direction of the incident wave to drive the rotor 32 of the permanent magnet motor 3 to do work next time.
如图3所示，本波浪能发电装置还包括水下无线充电设备9，水下无线充电设备9通过 电缆10和蓄电池4相连接，以为水下航行器100供电。As shown in Figure 3, the wave energy power generation device also includes an underwater wireless charging device 9. The underwater wireless charging device 9 passes The cable 10 is connected to the battery 4 to provide power to the underwater vehicle 100 .
在一具体实施例中，上述的张力腿5为弹性张力腿，并设置有两根；吸波浮体1、两张力腿5以及重力锚6四者之间成上宽下窄的梯形状。也就是说，整个装置主体是成上宽下窄的梯形状，而且是上轻下重，从而能够进一步保障浮力仓处于稳定平衡状态，促使吸波浮体与永磁电机定子发生相对转动，从而保障高效发电。In a specific embodiment, the above-mentioned tension legs 5 are elastic tension legs, and there are two of them; the wave-absorbing floating body 1, the two force legs 5 and the gravity anchor 6 form a trapezoid shape with a wide top and a narrow bottom. In other words, the main body of the entire device is in the shape of a trapezoid with a wide top and a narrow bottom, and is light at the top and heavy at the bottom, which can further ensure that the buoyancy chamber is in a stable and balanced state, and promote relative rotation between the wave-absorbing buoyant body and the permanent magnet motor stator, thereby ensuring Efficient power generation.
在一具体实施例中，吸波浮体1采用轻质蘑菇型，在波浪作用下运动响应敏感，从而使得吸波浮体1与浮力仓2发生相对运动驱动永磁电机3的转子32做功俘获波浪能并发电。In a specific embodiment, the wave-absorbing floating body 1 adopts a lightweight mushroom shape and is sensitive to movement under the action of waves, so that the wave-absorbing floating body 1 and the buoyancy chamber 2 move relative to each other to drive the rotor 32 of the permanent magnet motor 3 to perform work and capture wave energy. and generate electricity.
