Embodiment 1

[0031] Embodiment one: see figure 1 — Figure 4 , The main body of the wind power generation device of this embodiment includes a hydraulic piston cylinder 1, a steel cable 2, a column 3, a casing 4, a main engine 5, a fixed blade 6, movable blades 7, 8 and ground piles. Four steel cables 2 are obliquely pulled from the upper part of the column 3 to the ground, and fastened on the ground piles. The bottom center and the rear of the main engine 5 are respectively equipped with hinges, and the upper part of the column 3 is provided with a casing 4 that can rotate 360°. The top of the pipe 4 is hinged with the center of the bottom of the main engine 5 through a pivot pin 9, the side wall of the casing 4 is hinged with one end of the hydraulic piston cylinder 1, and the other end of the hydraulic piston cylinder 1 is hinged with the rear of the main engine 5. Hydraulic piston cylinder 1 is provided and recovered pressure oil by a remote control small-sized oil pressure station, man...

Embodiment 2

[0033] Embodiment two: see Figure 5 — Figure 9 In this embodiment, the blades are unfolded and folded on the power shaft 16. In this embodiment, the power shaft 16 of the main engine 5 is installed on the main shaft 22 through a rolling bearing 23. One end of the power shaft 16 is provided with a circular baffle 13, and the circular The baffle plate 13 is processed with a plurality of pin holes 26 (26A) connecting the blade seats 27, the other end of the power shaft 16 is provided with a gear 18 and a gear step 19, and the gear step 19 is provided with the pin hole 26 of the circular baffle plate 13. Corresponding concentric pin holes, the gear 18 transmits power to the main engine 5 responsible for power generation, and the action motor 21 meshes with the gear 18, wherein the blade seat of the fixed blade 6 is fixed by the long cylindrical pin 24 through the connecting pin hole 14 and the pin hole 26 in an interspersed manner. Connected between the circular baffle plate 13...

Abstract

The invention discloses a wind power generation device with rear-mounted blades. The wind power generation device comprises a stand column, a wind power generation main engine and the blades. The main engine is hinged to the top of the stand column. The blades are installed on the tail of the main engine in a rear-mounted mode. A hydraulic piston cylinder capable of moving telescopically is further hinged between the upper portion of the stand column and the rear portion of the main engine. A piston of the hydraulic piston cylinder moves telescopically to adjust changes of the pitching dip angle, on the stand column, of the main engine. At least three steel cables are uniformly distributed on the upper portion of the stand column and fixedly connected to the upper portion of the stand column. The other ends of the steel cables are fixedly connected with a ground pile in a cable-stayed mode. Due to the design, the steel cables of the stand column and the blades do not interfere with each other in the cable-stayed process of the cables, wind resistance influence is small, diameter space of the blades is enlarged, the swept area of wind power is increased, power is increased, the dip angle can be controlled, adjusted and rotated for harmonizing loads of wind power, and the wind power can be tracked automatically; due to high-gradient hilly area arrangement, the blades rotate in an inclined mode to make the front side face wind, and the wind power is fully utilized; with assistance of the cable-stayed steel cables, the structural cost can be reduced, the defect of the poor wind-proof capacity in tradition is overcome, and the wind power generation device is suitable for being arranged on coasts with strong wind.

Description

technical field [0001] The invention relates to a wind energy utilization device, in particular to a wind power generator whose blades are placed behind a column to rotate and the blades can be folded. Background technique [0002] In the conventional wind power generators that are common at present, the main engine used for power generation is installed horizontally on the top of the column, and the blades are arranged in front of the column. The layout feature of this type of front-mounted horizontal axis wind turbine is that the front of the blade rotates around the horizontal axis against the wind and is not disturbed by the floc flow of the column, but its disadvantage is that when the wind intensity increases, the vertical column will bear a large force Horizontal thrust; the blades and main equipment are arranged at the top of the column, which is heavy and the center of gravity is high. The column is made of steel in the design, and the installation requirements are ...
