Embodiment 1

[0022] Such as figure 1 and figure 2 As shown, a swing-blade wave energy generating device has a structural form of a one-to-one configuration of a circular rotating floating body, a swing leaf and a swing leaf frame. It includes a swing leaf 1, a swing leaf frame 2, a swing limiter 3, a floating body 4, a transmission shaft 5, a gearbox 6, a flywheel 7, a generator 8 and a fixed stand 9. Described pendulum blade 1 is a kind of streamlined blade, and there is a shaft 11 near the leading edge (referring to image 3 ), the swing blade 1 and the shaft 11 are not fixed, but can rotate relative to each other. The swing leaf frame 2 is divided into two sections from the middle hinge, the upper half section is fixed on the floating body 4, and the bottom half section is connected to the swing leaf 1 at the end. There are 4 (or more) sets of swing leaves 1 and their swing leaf holders 2, which are arranged and fixed along the outer circumference of the floating body 4, and the sha...

Embodiment 2

[0027] Such as Figure 4 and Figure 5 As shown in Fig. 1 , a swing-blade type wave energy generating device has a structure of a non-rotating floating body, and all swing leaves share a swing-leaf frame. It includes a swing leaf 1, a swing leaf frame 2, a swing limiter 3, a floating body 4, a transmission shaft 5, a gearbox 6, a flywheel 7, a generator 8 and a fixed stand 9. Described pendulum blade 1 is a kind of streamlined blade, and there is a shaft 11 near the leading edge (referring to Figure 6 ), the swing leaf 1 is fixed to the shaft 11, and the root of the shaft 11 has a protruding handle. The swing leaf frame 2 is cylindrical and shared by all swing leaves. The shaft 11 of the swing leaf 1 is arranged radially perpendicular to the transmission shaft 5 . The swing limiter 3, under the action of its drive mechanism, adjusts the stopper spacing (see Figure 6 The swing limiter 3) is used to change the swing angle of the swing blade 1 to adjust the output power.

Abstract

The invention provides an oscillating blade type wave energy electricity generation device, and relates to the wave energy utilization technology in the field of new energy resources. The oscillatingblade type wave energy electricity generation device mainly comprises oscillating blades, an oscillating blade frame, oscillation amplitude limiting devices, a floating body, a transmission shaft, a gearbox, a flywheel, a generator and a fixing platform frame. Each oscillating blade is a streamline type blade, a shaft is arranged on the portion, close to the front edge, of each oscillating blade,and the oscillating blades oscillate around the shafts in the water. A plurality of oscillating blades are arranged, and the shafts of the oscillating blades are radially arranged in the mode that theshafts surround the transmission shaft and are perpendicular to the transmission shaft. The oscillating blade frame is a mechanism for supporting the oscillating blades, transmits the kinetic energyof the oscillating blades to the transmission shaft, and can be downwards put into the water or upwards put away. Each oscillation amplitude limiting device is a limiting device, and the electricity generation power can be adjusted by changing the oscillating amplitude angles of the oscillating blades. The floating body floats along with waves, and is of a circular rotation type and a non-rotationtype. The transmission shaft can be a telescopic shaft with a universal joint, and can also be an ordinary hollow shaft. The flywheel is a mechanical energy storage device, and is used for storing orreleasing the rotation kinetic energy.

Description

technical field [0001] The invention relates to wave energy utilization technology. Background technique [0002] The energy contained in waves mainly refers to the kinetic energy and potential energy of ocean surface waves. The power density of huge waves caused by typhoons can reach thousands of kilowatts per meter of the wave surface, and the annual average wave power in the North Sea region of Europe, which is rich in wave energy, is 20-40kW / m 2 , the annual average wave power of most of China's ocean coasts is 2-7kW / m. [0003] Theoretical estimate of wave energy worldwide is 10 9 kW level, great utilization potential. [0004] At present, there are two types of wave energy devices that collect wave energy and convert them into electric energy or other forms of energy, which are arranged on the shore and float in the sea. According to the energy transmission form, there are four types: direct mechanical transmission, low pressure hydraulic transmission, high pressur...
