Jellyfish Turbine

Abstract

The invention discloses a jellyfish type water turbine which comprises a rotor mounted and being capable of rotating around an axis, wherein the rotor comprises blades, an inner ring and an outer ring; the blades are arranged between the inner ring and the outer ring, so as to enable the rotor to rotate around an axis where the inner ring is placed when the blades are positioned in running water; a blade fixing shaft is arranged on each blade and between the inner ring and the outer ring; the unfixed part of each blade is an elastic adjusting area; each elastic adjusting area can be used for automatically changing the angle of the unfixed part of each blade as per the variation of the impact force of water flow on each blade. According to the invention, the angle of the lower part of each adopted blade can be changed automatically under the action of elasticity and flexibility to compensate the instability caused by the variation of the impact force, so that the stable voltage and frequency of a hydro-generator are guaranteed as the rotating speed stability of the water turbine is improved, therefore, the hydro-generator has a wider applicable flow velocity range and higher efficiency; besides, the angle choice is more convenient as a blade adjusting shaft is used for adjusting an optimal angle for each blade.

Description

Technical field [0001] The invention relates to a turbine, in particular to a hydraulic turbine for extracting natural energy from water flow. Background technique [0002] There are many equipment that can be used to extract energy from water flow. Generally, hydraulic turbines are used. Each turbine has two or more blades, but the angle of the blades is usually fixed. When the water flow speed changes, if it needs to be changed The angle enables the turbine to achieve the best operation effect, and a relatively complex and large auxiliary mechanism must be installed to realize the blade rotation and change the angle to achieve the best operation effect. Larger hydro-generators have enough space to install the auxiliary mechanism for changing the angle of the rotor; for other smaller hydro-generators, there is simply not enough space to install the auxiliary mechanism for changing the angle of the rotor. Therefore, the traditional small water turbines are all fixed blades, and ...
