Ocean-current power generation device

Abstract

The invention provides an ocean-current power generation device. A generator, a generator shaft and an energy gathering mechanism are connected. The energy gathering mechanism is composed of a rotating shaft, a driving belt connected with the rotating shaft and vanes fixed onto the driving belt; a rolling axis of the driving belt (4) is identical to current direction of ocean currents; the vanes (1) are wing shaped; the vanes are identical with one another and in same installation relation with motion direction of the driving belt. By application of the wing principle, the vanes are allowed to acquire lifting force in ocean current to drive the generator to run. Compared with a conventional wheel-vane type energy gathering mechanism, the energy gathering mechanism provided with the single generator has larger and more flexible energy gathering range; compared with a garland-type or a paddle-wheel type and a parachute-type energy gathering mechanism, the energy gathering mechanism provided with the energy gathering mechanism cannot produce resistance with the ocean current during revolution, so that the vanes on a rotor can produce driving energy for the generator to deliver the ocean current in the whole circulation path; therefore, the ocean-current power generation device is large in energy gathering range and high in efficiency as compared with the prior art.

Description

technical field [0001] The invention relates to an ocean current power generating device. Background technique [0002] There is a huge amount of energy in the ocean, including tidal energy, wave energy, ocean current energy, temperature difference energy and salinity difference energy, etc. These energies are renewable and inexhaustible. In order to protect the earth and supplement the shortage of mineral energy, human beings have vigorously carried out the development and utilization of renewable energy, including of course the development and utilization of ocean energy. Because of the storability and transportability of electric energy, the development of ocean energy is currently dominated by power generation, some of which are generated by ocean current power generation equipment. Ocean currents include ocean currents and tidal currents, which are directional currents. At present, ocean current power generation equipment mainly includes vane type, parachute type and m...

AI Technical Summary

Problems solved by technology

The ocean current usually has a slow flow rate, so the energy per unit area is small. Among the above-mentioned various ocean current power generation equipment, except for the Coriolis ocean current power generation equipment, which has a strong energy gathering effect, other energy gathering functions are relatively strong. For example, the parachute type has only one parachute opening area, and the garland type has only the area of ​​a string of rotors, that is, the cross-sectional area of ​​the ocean current they actually use is small, so that the collected energy is not large.
