Arc blade type foldable tidal current energy generation device for water turbine

Abstract

The invention discloses an arc blade type foldable tidal current energy generation device for a water turbine. The device comprises a stretchable support pillar, wherein the support pillar has a hexagonal cylinder structure; a fixed base plate is arranged at the bottom of the support pillar; at least three foldable arc blades are connected with the fixed base plate through bolts; a movable base plate movably sleeved on the support pillar is arranged on the upper part of the fixed base plate; the movable base plate is connected with the lower parts of the blades through connecting rods; the control on the opening of the blades is realized by controlling the vertical movement of the movable base plate along the support pillar; a generating cabin is arranged at the top of the support pillar; a generator and an accelerating gearbox are arranged in the generating cabin; the support pillar, served as an input shaft, is connected with the accelerating gearbox; an output shaft of the accelerating gearbox is connected with the generator. The device provided by the invention is used for middle / small-scale generation; the volume of the whole device is reduced through the folding and closing of the arc blades and the contracting of the support pillar; the device can be conveniently transported and used; the arc foldable blades can extremely utilize the current energy.

Description

technical field [0001] The invention belongs to the technical field of tidal current energy generation, and in particular relates to a tidal current energy generating device of an arc blade type folding water turbine. Background technique [0002] Now focusing on the 21st century, countries around the world have already shifted their development focus to the sea. The huge energy contained in the ocean is the main resource lifeline of various countries. Ocean energy is a clean and renewable energy source. According to the estimates published by UNESCO in 1981, the total theoretically renewable total of five types of ocean energy is 76.6 billion kilowatts, and the development prospects are very promising. Our country has 18.000 kilometers of coastline and 6.960 islands with a total area of ​​6.700 square kilometers. Most of these islands are far from land and thus lack energy supplies. Therefore, in order to realize the development and development of my country's sea island...
