Description

Device for generating power by ocean wave kinetic energy

Technical field

The invention relates to a new energy power generation device, in particular to a device for generating power by ocean wave kinetic energy.

Background technique

The vast ocean contains huge energy. According to statistics, if the kinetic energy of ocean waves can be converted into electricity by 0.1%, it is equivalent to 5 times the total global energy consumption. Therefore, the ocean is a natural energy "engine", and the waves The energy density is high, which is 4-30 times that of wind energy. Compared with solar energy, wave energy is not affected by weather. Hailang Power is a new green project, and China is in the initial stage. Among the existing technologies that use wave power to generate electricity, some use the potential energy generated by changes in the height of the waves to generate electricity, and some use the kinetic energy generated by the waves rushing to the shore to generate electricity. In the technology, there are more or less problems with low collection efficiency of wave energy, poor stability performance, and reduction in power generation efficiency.

Summary of the Invention

In order to make up for the shortcomings of the above-mentioned wave power generating device, the present invention provides a wave power generating device, which can collect wave energy to the maximum and can continuously generate power.

The technical scheme adopted by the present invention is that the device for generating power by ocean wave energy includes a wave energy conversion component and a generator component, and the generator component is composed of a generator, a gearbox, and a first inertia which are sequentially connected to a flywheel shaft. It consists of flywheel and second gear.

The wave energy conversion component is composed of a water tank and a plurality of impact turbines installed on the top surface of the water tank. The water inlet of the water tank is in the shape of a funnel with a wide outer width and a narrow inner diameter. The water turbine rotates, and two articulated lifting plates are arranged inside the water tank. One end of one of the lifting plates is hinged to the bottom plate of the water tank, and the other lifting plate is connected to the height adjusting member. The rotary shaft of the impact water turbine is provided with a first gear. The first gear and the second gear are coupled through a chain.

The device for generating power by ocean wave kinetic energy further includes an inertia flywheel assembly. The inertia flywheel assembly is composed of a rotating shaft, a support base, and a second inertia flywheel and a clutch respectively fixed on the rotating shaft. The clutch is connected to the rotating shaft of the flywheel. When the wave speed is high, the inertia flywheel assembly is connected through the action of the clutch. The operation of the inertia flywheel makes the generator speed higher and more stable, and the power generation is larger.

Further, the impact water turbine is installed in parallel on the top surface of the water tank, so that half of the blades of the water turbine fall into the water tank, and the other half is exposed outside the water tank.

Further, the distance between the impact water turbine and the top surface of the water tank can be adjusted by a height adjusting member installed on the support base of the impact water turbine, and the height of the impact water turbine can be adjusted according to the height of the waves, so that when the waves hit the turbine blades, Best impact point.

Further, the width of the lifting plate is the same as the width of the interior of the water tank. The lifting plate can be raised and lowered as the height of the impact turbine changes, so that the optimal impact point can be obtained when the waves impact the blades of the turbine.

Further, the width of the impact turbine is slightly smaller than the width of the water tank, increasing the blade area and collecting more wave energy.

Further, the arc of the bucket near the axial end of the impact type turbine is small, and the arc of the far end is large, forming a hook shape. The bucket is provided with a plurality of spaced baffles to prevent the waves from generating buffering motion in the bucket. The buckets have side blades at both ends, and this bucket structure of the turbine is beneficial for collecting more wave energy.

Further, the first gear and the second gear are unidirectional multi-stage gears, which can adjust the rotation speed of the generator shaft and prevent reverse rotation.

Further, the impact type water turbine is provided with a sealed water turbine protective cover, so that the water bucket exposed outside the water tank is exactly contained in the protective cover, so as to avoid the impact of the waves flowing from the outside of the water tank to reduce the speed of the water turbine.

Further, the generator assembly and the inertia flywheel assembly are further provided with a sealed protective cover, so that the main components such as the generator, the gearbox, the first inertia flywheel, the second inertia flywheel, and the clutch are contained in the protective cover to avoid seawater erosion, At the same time, the first inertial flywheel and the second inertial flywheel are prevented from being reduced by the impact of the waves.

The beneficial effects of this utility model are:

First, the unique structural design of the water tank and the impact turbine bucket fully absorbs the kinetic energy of the waves, providing a prerequisite for generating more electricity.

Second, the height of the impact turbine can be adjusted according to the size of the waves, so that the best impact point can be obtained when the waves impact the bucket of the turbine.

Third, the use of unidirectional multi-stage gear can adjust the speed and prevent reverse, which is better for collecting the kinetic energy of the waves.

4. When the speed of large waves is high, the inertial flywheel group is introduced to assist the work, so that the speed of the inertial flywheel is more stable and the output kinetic energy is greater.

Fifth, the turbine protective cover seals the blades in the protective cover to prevent the bucket from being impacted by the waves outside the water tank to reduce the speed.

6. The protective cover of the generator assembly and the inertia flywheel assembly seals the first inertia flywheel and the second inertia flywheel in the protective cover to prevent the impact of the waves and reduce the speed.
