Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the "front end" and "rear end" hereinafter are both defined for the flow direction of waves, wherein "front end" refers to the direction facing the incoming wave. The "back end" refers to the end away from the incoming wave direction.

[0017] Such as figure 1 As shown, the direction pointed by the arrow is the incoming wave direction. The present invention includes a number of wave energy collection floating bodies 2 connected in series through two-way hinges 1, several wave energy collection floating bodies 2 connected between two adjacent sections and symmetrically distributed on the upper and lower ends of the central axis of the wave energy collection floating body 2. Rod type hydraulic device 3, and the water inlet and outlet device that connects seawater and rod type hydraulic device 3. The bottom of the first wave energ...

Abstract

The invention relates to an output-adjustable raft type wave pump which comprises wave energy acquisition buoys, hydraulic devices and water inlet and outlet devices. The first wave energy acquisition buoy is anchored on the seabed through an anchor chain. Each wave energy acquisition buoy comprises a rib plate, two vertical slides are tightly connected on each of the front end face of each rib plate and the rear end face of the previous wave energy acquisition buoy, and a rotary part base which is vertically adjustable is arranged on each slide. Each rotary part base on the rib plates is rotationally connected with the bottom end of a cylinder body of the corresponding hydraulic device through a connecting rod, the upper side wall and the lower side wall of the rear end of each cylinder body is provided with a water inlet and a water outlet respectively, and the upper side wall of the front end of each cylinder body is provided with an air hole. A piston rod is inserted in each cylinder body, the rod end of each piston connecting rod horizontally penetrates a through hole formed in the front end face of the corresponding wave energy acquisition buoy and is then rotationally connected with the corresponding rotary part base on the rear end face of the previous wave energy acquisition buoy, and a seal cover is arranged on each through hole. The size of each through hole satisfies the condition that the hydraulic device rotationally connected on each rotary part base and the front end face of the corresponding wave energy acquisition buoy do not interfere with each other when each rotary part base is located at the highest point or the lowest point of the corresponding slide.

Description

technical field [0001] The invention relates to a wave pump, in particular to a raft type wave pump with adjustable output. Background technique [0002] At present, non-renewable energy sources such as fossil fuels are one of the most important energy sources for human production and life. However, with the growth of global energy use, fossil fuels will become increasingly exhausted. In addition, excessive carbon emissions from fossil fuels will cause environmental pollution. And global warming has become one of the greatest challenges facing mankind today. Therefore, seeking renewable green energy is an important measure to solve energy crisis and environmental problems. [0003] Wave energy is a renewable clean energy with the highest energy flow density, the highest grade and the widest distribution in ocean energy. It is people's long-term desire to convert the inexhaustible and inexhaustible wave energy into useful energy. Since the 21st century, the international c...
