Abstract

The invention relates to a straight-wing water flow power generation device. The gear box is fixed in the base, and the rotating disk is arranged above the base. ; The main shaft is linked with the shaft of the generator, the main shaft and the gear box rotate in cooperation, the upper end of the main shaft passes through the upper wall of the gear box and is fixedly connected with the rotating disk; Out of the main shaft and the gear box, it is connected with the water flow direction controller. The upper end passes through the lower wall of the rotating disk to move with the central gear in the rotating disk. This end is in rotation with the upper wall of the rotating disk; Several paddle gears are evenly distributed on the paddle shaft, and the paddle gear is connected with the central gear through a transmission member; the paddle shaft protrudes from the upper wall of the rotating disk, and is fixedly connected to one end of the paddle, and the other end of the paddle rotates to match On the deflector plate; the rotating plate rotates once, and the blade rotates half a circle around its own axis. The present invention can be suitable for running at high and low speeds.

Description

technical field [0001] The invention belongs to the technical field of water flow power generation devices, in particular to a straight wing water flow power generation device. Background technique [0002] At present, hydropower generation mainly uses the water level drop to convert the rotation of the water turbine to drive the generator to generate electricity. There are two main forms of more mature hydropower generation: storage power generation with high water head and tidal power generation with low water head. Water storage power generation requires supporting projects such as blocking the river, repairing dams and building ship locks, and tidal power generation requires large-scale engineering transformation of the bay. Therefore, the current hydropower facilities require huge investment, high maintenance costs, and have a significant impact on the environment. The main types of existing water turbines are: impact water turbine and impact water turbine, impact wate...
