Embodiment Construction

[0025] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, Features and their functions are described in detail below.

[0026] Such as figure 1 As shown, the impeller structure of a wave energy power conversion device in the present invention includes an impeller body 1 and a plurality of blades 2 evenly distributed on the impeller body.

[0027] Each of the blades 2 is helical, so that the area of ​​the blades is as large as possible in the same size range, so that the force-bearing area of ​​the impeller increases in waves, which can overcome the current disadvantages of small force-bearing area and low efficiency of the impeller. Make effective improvements. The structure of each of the blades 2 is the same, so as to facilitate processing and bear force in waves.

[0028] Such as figure 1 and Figure 4 As shown, the thickness of the blade in each ...

Abstract

The invention relates to an impeller structure and particularly to an impeller structure of a wave-energy power generation conversion device. The structure comprises an impeller body and a plurality of blades which are distributed on the impeller body evenly, wherein each blade is in a spiral shape. According to the structure, in order to improve the conversion efficiency of wave-energy power generation, an existing shape of the blade is discarded, the shape of the blade is changed, spiral blades are adopted, the stressed area of the impeller in waves is increased, the same rotating direction of the impeller in waves of different directions is guaranteed at the same time, and the conversion stability of wave energy is guaranteed well, so that the conversion efficiency of the wave energy is improved. Besides, the problem of up-and-down motion of the impeller under the action of waves can be solved due to the spiral shape.

Description

technical field [0001] The invention relates to an impeller structure, in particular to an impeller structure of a wave energy power conversion device. Background technique [0002] Waves are undulating movements caused by the gravity of wind and water. They have certain kinetic energy and potential energy. Wave energy power generation refers to the process of converting the energy dynamics of waves into electrical energy. Because ocean waves contain huge energy, it is expected that with the depletion of fossil energy resources and the advancement of technology, wave energy power generation will gradually occupy a certain position in countries rich in wave energy. Therefore, there are more and more researches on energy in this field, converting wave energy into mechanical energy, and then driving a generator to generate electricity through a transmission mechanism. [0003] In the existing mechanical wave energy generation, the key of wave energy utilization is the wave ene...
