Problems solved by technology

The above-mentioned measures are effective to a certain extent, but at the same time, they will also bring about adverse effects such as higher operating and production costs.
[0003] As mentioned above, the pendulum wave power generation device has a large wave bearing surface, and it will be subjected to a large wave impact force in large waves, which will cause the swing of the pendulum plate to be too large or even exceed the limit of its normal working position, causing fatal damage to the pendulum plate device. mechanical or structural damage

Abstract

The invention discloses a gravity pendulum type wave power generation device with an adjustable wave-bearing area. The gravity pendulum type wave power generation device comprises an outer frame, swing plate units, a generator, a motor mounting platform, hinge supports, adjusting motors, rotating shafts, a power conversion mechanism and a control device, wherein the outer frame is movably connected to the motor mounting platform through the hinge supports at the top, the swing plate units are arranged in the outer frame in a rotating mode through the rotating shafts at the upper end and the lower end, the adjusting motors are located in a watertight cabin at the top end of the outer frame and are connected to the rotating shafts at the upper ends of the corresponding swinging plate units through couplers, the outer frame is in driving connection with the input end of the generator through the power conversion mechanism, and the control device is connected to the generator and the adjusting motors through circuits. The gravity pendulum type wave power generation device has the advantages that the wave-bearing area of the device is controlled by adjusting the posture of the swing plate units, and therefore the wave force output of the whole device can be adjusted, stable output of power under different sea conditions can be realized, and normal work and survival capability of thedevice in the extreme high-wave environment can be guaranteed.

Description

technical field [0001] The invention relates to a wave power generation device, in particular to a pendulum type wave power generation device with adjustable wave front area to change the wave load on the device. Background technique [0002] Environmental, energy and population pressures have accelerated the pace of human development of the ocean. There are abundant wave energy resources in the ocean, and various wave power generation devices have been invented to convert wave energy into electrical energy. The marine environment where wave power generation devices are located is very complex, so an effective wave power generation device must meet the characteristics of continuous and stable power generation, better survivability and maintainability. The pendulum wave power generation device has the characteristics of large geometric scale and large wave-facing area, so its structural strength has high sensitivity to wave loads. However, most of the pendulum wave power ge...
