Double-channel ocean current energy power generating device

Abstract

Disclosed is a double-channel ocean current energy power generating device which comprises a water flow channel, a power generating mechanism and a gate mechanism. The power generating mechanism is arranged in the water flow channel and provided with a generator and an impeller connected with the generator, the gate mechanism is arranged on two sides of the impeller and provided with an inflow gate mechanism and a backflow gate mechanism, when seawater flows into the water flow channel, the inflow gate mechanism is opened and the backflow gate mechanism is closed to form a inflow channel, and when the seawater backflows into the water flow channel, the backflow gate mechanism is opened and the inflow gate mechanism is closed to form a backflow channel. The double-channel ocean current energy power generating device converts all back and forth movement of ocean current in off shores and close to island shores into unidirectional rotation of the impeller, so that stability of output power of ocean current energy is improved; compared with existing ocean current energy structures, the double-channel ocean current energy power generating device is simpler and more reliable in structure due to omission of a heavy ratchet wheel and an accumulator; and the horn-shaped water flow channel is in favor of increasing flowing speed of ocean current and improve power generating capacity.

Description

technical field [0001] The invention belongs to the technical field of ocean current energy power generation, and in particular relates to a dual-channel ocean current energy power generation device, which is suitable for power supply for fishermen at sea, buoys at sea, seaside lighting, and lighting and power on islands. Background technique [0002] At present, there are many types of ocean current power generation devices at home and abroad, and the related system structures are relatively complex and bulky, involving alignment devices, energy storage devices, and indirect drive devices such as hydraulic or pneumatic drive motors, etc., with low efficiency; Alignment devices need to adjust the blade angle and blade spacing to align with the current. At the same time, most of the existing ocean current energy is suitable for areas where the ocean current velocity is greater than 2m / s; for areas where the ocean current velocity is less than 2m / s, the power generation effici...

[0002] At present, there are many types of ocean current power generation devices at home and abroad, and the related system structures are relatively complex and bulky, involving alignment devices, energy storage devices, and indirect drive devices such as hydraulic or pneumatic drive motors, etc., with low efficiency; The alignment device needs to adjust the blade angle and blade spacing to align with the sea current

At the same time, most of the existing ocean current energy is suitable for areas where the ocean current velocity is greater than 2m / s; for areas where the ocean current velocity is less than 2m / s, the power generation efficiency is extremely low, and it is currently difficult to apply it on a large scale in practice
