Ocean wave energy and solar energy integrated power generation device and working method as well as application thereof

Abstract

The invention relates to an ocean wave energy and solar energy integrated power generation device, which comprises a concave base fixed on a coastline, and a solar energy battery acquisition part arranged on the concave base. A water flow channel is arranged on the lower part of the concave base in a penetrating manner; a baffle driven by sea waves is arranged in the water flow channel; a hydraulic rod and a hydraulic cylinder both being driven along the flowing direction of the sea waves are arranged on the concave base; a rotating shaft is fixedly arranged on the middle part of the baffle; the baffle is arranged in the water flow channel through the rotating shaft; the lower part of the baffle does reciprocal pendulum motion under the driving of the sea waves; a rotating shaft support point enables the upper part of the baffle to drive the hydraulic rod and the hydraulic cylinder to do reciprocating motion for power generation.

Description

technical field [0001] The invention relates to a marine wave energy and solar energy integrated power generation device and its working method and application, belonging to the technical field of wave power generation and solar power generation. Background technique [0002] The environmental degradation caused by the energy crisis and the greenhouse effect has always been the driving force for the development of new energy sources. Although the development of wave energy is nearly ten years behind wind energy and solar energy, in terms of energy density, wave energy is 3-40 times that of wind energy. If wave energy can be effectively developed, the economic benefits it will bring Benefits are much higher than wind and solar energy. [0003] Currently, there are many types of wave energy generating devices. According to the different absorption methods, it can be divided into point absorption device, termination type device and mitigation type device. According to differ...

Problems solved by technology

But this structure has a lot of disadvantages, mainly in two aspects: first, the baffle has a large area, and in the process of swinging the baffle, it will be stressed due to the action of waves, which will hinder the swing of the baffle. force, reducing the efficiency of power generation

Second, the overhang adds bulk and weight to the baffle, thereby increasing the cost of the system

However, there are disadvantages in such a design, mainly in two aspects: first, using a hinged connection, it is easy to break and fail when subjected to shock and vibration, thus affecting the service life of the entire system

Second, the hinged connection method must be used to connect the piston cylinder to the thick wall above the base or on both sides of the thick wall, so that the number of connected piston rod cylinders is limited

As we all know, the energy contained in ocean waves is huge, and it can drive multiple hydraulic cylinders to work at the same time. This system cannot realize the joint work of multiple hydraulic cylinders.
