Embodiment Construction

[0007] figure 1 As shown, a wind turbine in which the cylinder automatically pushes the tail rudder, the wind pushes the wind blade 1 to rotate to generate power, and the power shaft 2 connected to the wind blade 1 transmits the power to the passive machine 3 to do work, which is characterized in that the passive machine 3 The rear end of the tail rudder is connected with the bracket 9, and the tail rudder 7 is connected to the rear end of the bracket 9 by the rotating shaft 6, so that the tail rudder 7 can rotate around the rotating shaft 6, and the tail rudder 7 is provided with a moment arm 5, and the cylinder 4 The shaft of the power rod is connected to the arm 5, and the other end of the cylinder 4 is connected to the equipment. A tension spring 8 is hung between the arm 5 and the bracket 9. The blade 1 and the tail rudder 7 maintain a vertical angle within the rated wind speed. , so that the wind-receiving surface of the fan blade 1 is kept at a perpendicular angle to th...

Abstract

The invention belongs to the filed of wind energy, and in particular relates to a wind turbine with an air cylinder capable of pushing a tail rudder automatically. The wind turbine is characterized in that the rear end of a driven machine is connected with a bracket (9); the tail rudder (7) is connected to the bracket by a rotary shaft (7); the tail rudder can rotate round the rotary shaft (6); the tail rudder (7) is provided with an actuating arm (5) which is axially connected with a power lever of the air cylinder (4); a tension spring (8) is hanged between the actuating arm (5) and the bracket (9); within a rated wind speed, a blade (1) and the tail rudder (7) rotate vertically; when the wind speed exceeds the rated wind speed, the air pressure in a device increases, the air cylinder (4) overcomes the tension of the spring (8) to start to work, the tail rudder (7) is pushed surrounding the rotary shaft (6) to move from the original position A1 to A2; the wind surface of the blade (1) and the angle of wind direction change, and the aim of speed regulation is achieved; and when the wind speed exceeds the speed regulation range, the air cylinder (4) works with a full rate, the tail rudder (7) is pushed to reach the rated angle, thus the wind surface of the blade (1) is parallel with the wind direction, and the vehicle stops automatically to avoid from danger.

Description

technical field [0001] The invention belongs to the field of wind power energy, in particular to a wind power machine in which a cylinder automatically drives a tail rudder. Background technique [0002] At present, fans of small wind power generation and wind pumping pumps generally use tail rudders to keep the wind-receiving surface of the wind turbine blades at a perpendicular angle to the wind direction. The rudder is pulled sideways to avoid danger. When there is no human on duty, the wind turbine is easily damaged by strong winds. Contents of the invention [0003] In order to overcome the above-mentioned technical deficiencies, a wind turbine with a cylinder that automatically drives the rudder is invented, which can automatically adjust the speed within the rated wind speed. Speed ​​regulation and complete automatic parking avoidance. [0004] The technical solution adopted by the present invention to solve its technical problems is: a wind turbine with a cylinde...
