Problems solved by technology

Although this technical solution solves the problems that the existing wing-type wind turbines are difficult to manufacture and the maximum power generation is difficult to further increase, it not only has the disadvantages of complex structure and high manufacturing cost due to the installation of a windshield control shell, but at the same time, Because the blades are fixedly connected to the columns, while the sails in the wind flow channel are pushed by the wind, the sails on the opposite side will also be affected by part of the wind force and produce thrust in the opposite direction to the columns, resulting in insufficient wind power waste

Abstract

The invention discloses a wind power generation sail which comprises an upright column and a plurality of sail blades, wherein the upright column is coaxially connected with the input end of a generator; the sail blades are vertically arranged; the sail blades orderly enable the upright column to continuously rotate in the same direction under the action of the wind; the upright column is coaxially fixed with a flange; the flange is connected with cross beams; the cross beams are perpendicular to the upright column; the quantity of the cross beams is corresponding to that of the sail blades; the cross beams are evenly distributed in the circumferential direction of the flange and fixedly connected with support columns; the sail blades are rotatablely supported on the cross beams; the sailblade and the rotating connecting axis on the cross beam are positioned at the far end of each cross beam; when the wind receiving surface of the sail blade faces the wind, the back surfaces are attached to the front side surface of the cross beam; the support columns and the lower ends of the sail blades are respectively fixedly connected with a universal trundle; and the support columns and thesail blades are supported on the hard ground respectively through the universal trundles. The invention fully utilizes wind power, and has the advantages of simple structure, convenient manufacture, low cost and long service life.

Description

technical field [0001] The invention relates to a sail for wind power generation of a wind power generation device, in particular to a vertical wind power generation sail for vertical wind power generation. Background technique [0002] Wind energy is a kind of clean energy. In today's increasingly tense world energy sources, wind energy has attracted more and more attention. The wind rotor is an important part of the wind turbine. Whether the structure of the wind rotor is reasonable or not is directly related to the operating efficiency of the wind turbine. At present, the common wind turbine wind rotor is a propeller-type wind rotor composed of three or more blades. The wind rotor and the main body of the generator constitute the generator head, which is installed on the wind turbine tower in an approximately vertical manner. . Because the wind rotor with this structure has a small wind receiving area, the power generation of the generator is limited to a certain extent...
