Problems solved by technology

[0007] The above three types have their own advantages and disadvantages, but a common problem is the intermediate link of converting wave energy into electrical energy, which has low efficiency and large fluctuations in power output. This is also one of the main reasons that have affected the large-scale development and utilization of wave power generation for many years.

Embodiment Construction

[0022] Each hull of the submersible catamaran (1) is composed of upper and lower independent spaces. The buoyancy of the upper space can make the hull and the loaded generator (3), gearbox (4) etc. can be in a suspended state in the water; the buoyancy of the lower space can make the whole ship in a semi-submerged floating state; The lower and lower parts are equipped with an exhaust port and a drain port. After opening, the hull can be stopped at any position from the water surface to the water through the adjustment of the air pressure, so that it can still work normally when the wind and waves are relatively large. The hull is a triangular streamlined structure, and the deck is connected (6) in a grid shape to facilitate water penetration. The generator (3), gearbox (4), pull-off bearing (5), etc. are wrapped and sealed with a boat-shaped seal chamber (2). Speed ​​to suit different waves or currents. The center of gravity of the device structure is at the central point of...

Abstract

The invention is a medium or small sized universal power generation device, from wave energy or ocean current energy, with features of low construction cost, low cost, high-energy conversion efficiency and broad applicability scope. The device adapts to power generation in environments from low wave to high wave; meanwhile, the invention also adapts to power generation through energy conversion from ocean currents, rivers, brooks and etc in water channel speed of 2m / s. The power generation volume of the device can be sized from hundreds of watts to hundreds of kilowatts.

Description

technical field [0001] The invention is a universal generating device for wave energy and ocean current energy. The utility model belongs to the technical field of utilization of ocean wave energy and ocean current energy. Background technique [0002] In 1992, the United Nations listed wave power generation as the first priority in the development of marine renewable energy. According to the estimated figure of UNESCO in 1981, the wave energy of the world's oceans is 3 billion kilowatts. There are about 70 million kilowatts along the coast of China. Within the wave length range of 1M, when the wave height is 2M and the wave period is 6S, the generating power is 24KW; when the wave height is 3M and the wave period is 11S, the generating power can reach 130KW. At present, countries such as Norway, Japan, the United Kingdom, the United States, France, Spain and China have built a number of experimental wave power generation devices ranging from tens of watts to hundreds of ...
