Problems solved by technology

[0002] At present, there are mainly the following problems in the use of over-wave wave energy generation devices: the safety reliability and wave energy conversion rate cannot be balanced, the construction cost is high, the terrain or sea conditions are strongly restricted, and the scale cannot be well realized. Industrialized and industrialized applications; greatly affected by wave height, unstable power generation
Its disadvantages are: the components of the wave energy generation device are too complicated, inconvenient to maintain, and it floats on the sea surface, the reliability is poor, the conversion rate of wave energy is low, and it is difficult to realize practical application

Embodiment 1

[0029] see Figure 1-Figure 8 , the invention includes a wave energy collection system, a power generation system and a self-opening and closing electric control system. The wave energy collection system includes a reservoir 101 and a wave guiding platform 102. The wave guiding platform 102 is a wedge-shaped structure with a right-angled triangle on the side. Waves enter the reservoir 101 along the wave guiding surface 103 of the wave guiding platform 102. The outside of the reservoir 101 is fixedly connected to the wave-guiding platform 102, the top of the wave-guiding platform 102 is connected to the top of the side of the reservoir 101, the bottom of the wave-guiding platform 102 extends obliquely to the bottom plane of the reservoir 101, and the wave-guiding surface of the wave-guiding platform 102 The slope of 103 is set to 2:3, which is suitable for wave climbing and climbing. The upper part of the reservoir 101 is hollow and is a water inlet A104, and a working platfor...

Embodiment 2

[0039] Except following difference, other is with embodiment 1.

[0040] see Figure 5 , the water turbine 204 is an axial flow paddle type water turbine, including a runner 211 and blades 210, the blades 210 are installed on the runner 211 perpendicular to the axis line of the axial flow paddle type water turbine, and the number of blades 210 is 4-6 pieces . The axial-flow blade water turbine 204 provided by the technical solution can operate under a low water head difference, which reduces the requirement of the wave energy power generation device on the water head.

Abstract

The invention relates to an overtopping wave energy power generation device which is high in efficiency and reliability. The overtopping wave energy power generation device comprises a wave energy collecting system, an electricity generation system and a self-start-stop electric control system. The wave energy collecting system comprises a water storage pool and a wave guiding table and the wave guiding table is fixedly connected with the outer side of the water storage pool. A power generation system comprises a water outlet groove, a water turbine and a generator. One end of the water outlet groove is located in a hollow structure of the bottom of the water storage pool and the other end of the water outlet groove is located at the outer side of the water storage pool. The water turbine is located in the water outlet groove, the generator is located above the water turbine, and the water turbine and the generator are connected through a rotary shaft. The self-on-off electric control system is arranged on an operation platform and comprises a balance weight, a valve and an electric control box. The electric control box comprises a power source, a float switch and a lifting motor. The lifting motor is connected with the valve through a pulley and a mooring rope. Dynamic energy storage and stable power output of the overtopping wave energy power generation device are achieved and the wave energy use ratio and the conversion efficiency are greatly improved.

Description

technical field [0001] The invention relates to a power generation device utilizing wave energy, in particular to a wave-over type wave power generation device with high efficiency and high reliability. Background technique [0002] At present, there are mainly the following problems in the use of over-wave wave energy generation devices: the safety and reliability and the wave energy conversion rate cannot be balanced, the construction cost is high, and the terrain or sea conditions are strongly restricted, and the scale cannot be well realized. Industrialized and industrialized applications; greatly affected by wave height, power generation is unstable. [0003] The patent application with application number 200810121813.0 discloses a floating cofferdam type wave energy generating device, which utilizes the potential energy and kinetic energy of waves during tidal fluctuations and converts them into electrical energy through a hydroelectric generator. Its disadvantages ar...
