Embodiment Construction

[0014] Such as figure 1 As shown, an auxiliary power take-off structure for ocean current power generation includes at least one auxiliary power take-off frame 2, the auxiliary power take-off frame 2 is installed on the facing surface of the power generation unit frame 5, and is located outside the power generation unit frame 5; The power frame 2 has at least one inclined plane frame 3, one end of which is connected to the power generation unit frame 5 on the upstream side, and forms an acute angle with the power generation unit frame 5 on the upstream side that it blocks. In order to solve the problem of power take-off at low flow rates, the water is introduced into the positive work side of the rotating frame in the frame of the power generation unit through the inclined plane frame on the water facing surface, and the side doing negative work on the return journey of the rotating frame is blocked by the inclined plane frame, effectively Block the impact of incoming water on...

Abstract

The invention discloses an ocean current power generation auxiliary force taking structure. An auxiliary force taking frame is at least included. The auxiliary force taking frame is arranged on the upstream face of a power generation unit frame and located on the outer side of the power generation unit frame. The auxiliary force taking frame is at least provided with one slope frame. One end of the slope frame is connected to the upstream face power generation unit frame, and the acute angle is formed between the slope frame and the upstream face power generation unit frame shielded by the slope frame. Through the arrangement of the auxiliary force taking frame, negative work on the non-acting side from incoming water is reduced, the water flow of the acting side is increased, the effect is improved, and increasing of the final conversion rate is achieved; and winding of return blades through garbage is stopped, the garbage directly follows water flow to flow through equipment from theclosed blades, damage to the equipment is reduced, and the maintenance period is prolonged.

Description

technical field [0001] The invention relates to an auxiliary power-taking structure for ocean current power generation, and belongs to the technical field of ocean current power generation equipment. Background technique [0002] In ocean current power generation, relying on the rotating structure to take force, the tidal energy of the ocean current is converted into mechanical energy and then into electrical energy. The existing ocean current power generation structure does not have a good technical solution in the case of low flow velocity (less than 2m / s). The reason is that the ocean current is a kind of liquid, which has its unique characteristics. When the power generation equipment is put into the ocean current, as given in 201510050922.8 A kind of flowing water power generation device, the water flow pushes the rotating frame to rotate. However, one side of the rotating frame is affected The force does positive work, and the other side is the force to do negative wo...
