Problems solved by technology

However, since the tidal current energy is a kind of energy that changes with time, the magnitude of its instantaneous energy is beyond our control, so the speed of the conventional water turbine is not constant, and the voltage generated by it is also unstable.

Abstract

The invention discloses a water turbine structure capable of providing stabilized voltage. The water turbine structure comprises an input shaft of a generator rotor, and is characterized in that the input shaft is of a hollow cylinder shape; the end part of the input shaft is connected with a water turbine shell through a flange plate; a pull rod which extends into the input shaft is arranged in the water turbine shell; one end of the pull rod is fixedly connected with a regular triangular prism which is arranged in the water turbine shell, and the other end of the pull rod is connected with a reset spring; three side surfaces of the regular triangular prism are fixedly connected with a rack respectively; all the racks are meshed with gears which are arranged on blade rotary shafts; a blade which is positioned outside the water turbine shell is arranged at the top end of each blade rotary shaft; the blade rotary shafts are rotatably supported on the water turbine shell and can rotate around the self axes; limiting plates are further arranged on two axial sides of the regular triangular prism in the water turbine shell respectively.

Description

technical field [0001] The invention relates to a water turbine structure, in particular to a water turbine structure capable of providing stable voltage. Background technique [0002] Tidal current energy mainly refers to the sea current generated with the tidal phenomenon, and the tidal current changes its magnitude and direction twice a day. The tidal current energy generator can directly use the water flow of the ebb and flow to impact the impeller and other mechanical devices to generate electricity. There are many different types of tidal current energy generation devices at home and abroad. Such as horizontal axis tidal energy turbines, shaft tidal energy turbines, oscillating hydrofoil tidal energy devices, etc. However, since tidal current energy is a time-varying energy source, the magnitude of its instantaneous energy cannot be controlled by us, so the rotational speed of conventional hydro turbines is not constant, and the voltage generated by it is also unstab...
