Embodiment Construction

[0023] pass figure 1 with figure 2 , the first embodiment of the water turbine blade type power generation device of the present invention will be described. In the middle of the apparatus housing 1, a generator 2 having input shafts 2a, 2a on both sides is fixed. On both sides of the generator 2, water wheel blade type power generating devices 3, 3 are arranged. This water turbine blade type power generation device 3 has the following structure.

[0024] The rotating body 10 having an octagonal outer circumference is fixed to a rotating shaft 11 , and the rotating shaft 11 is connected to the input shaft 2 a of the generator 2 via a joint 12 . The rotating shaft 11 is rotatably supported by a support plate 14 via a bearing 13 , and the support plate 14 is fixed to the bottom plate of the device housing 1 . On the vane mounting surface 10a on the outer periphery of the rotating body 10, an L-shaped vane 15 formed of a fluid receiving portion 15a for water flow or the like...

Abstract

The invention relates to a water turbine blade type power generation device, which can firmly set up a blade plate through a rotator on advancing direction and can reliably topple over the blade plate aside the rotator on a returning direction. Under the rotator (10), a fluid channel frame (21) is arranged in the manner of forming a fluid channel (20); a blade (15) is rotatably arranged on the rotator (10); a fluid receiving part (15a) and a stopping part (15b) shorter than the fluid receiving part (15a) are L-shaped; the stopping part (15b) is arranged on one side of the fluid receiving part(15a) loading the fluid pressure of the fluid channel (20) in the manner of keeping the fluid receiving part (15a) upright; on the periphery of the rotator (10), without influencing the rotation of the blade (15), a blade channel frame (22) is around the rotator (10) and the fluid receiving part (15a) comprises a base fluid receiving section (15a1) and a hammer (15a2) fixed on the front end thereof.

Description

technical field [0001] The present invention relates to a water turbine blade type power generation device for obtaining hydroelectric power by utilizing, for example, water currents such as rivers and seas, ocean currents, and the like. Background technique [0002] As small and simple impellers for hydroelectric power generation, propeller-type and water-turbine-type impellers have been proposed. With the propeller type, since water has a very large resistance compared to air, when used for hydroelectric power generation, sufficient rotation speed and torque cannot be obtained, which is not good. In contrast to this situation, the water turbine type can be easily realized by utilizing the current in the vicinity of the water surface as it is. However, when the water turbine type is installed in water or in the sea and is rotated by currents or sea currents, there are problems as follows. [0003] Since on the forward motion side (same direction as the flow) and return mo...
