Embodiment 1

[0051] Embodiment 1: The integrated vertical axis windmill used for small power generation devices such as Figure 13 As shown: the fan frame adopts 2-4 layers, each layer is 3 meters, and its small fan blades adopt 4-10 on each side, and its structure is: wind direction indicator 1 and at least 2-3 layers of frame pillars 15 that can be plugged up and down And reinforced by steel cables 14, the fan blade frame 8 is arranged in the frame pillar 15, and the transmission shaft 12 is vertically placed on the frame pillar and the center of the fan blade frame, fixedly connected with the fan blade frame 8 and movably matched with the frame pillar 15; the wind direction The indicator 1 is sequentially connected to the wind direction indicating sensor 2 to the hydraulic propeller 3 in the blade frame 8, and the transmission device is connected to the blade frame 8 and 4-10 pairs of vertical axis small fan blades 6 and 7 central axes in the two wings, the small fan The upper and lower...

Embodiment 2

[0052] Embodiment 2: High-power machines for large-scale power plants, such as Figure 12 As shown, fan blade frames with more than 8-10 layers are used, and more than 10 small fan blades are used on each side. The other structures are the same as above, and will not be described in detail.

[0053] Practice has proved that the integrated vertical axis windmill of the present invention has the same fan blade running direction as the wind direction, which is in line with the basic condition of Newton's second law of motion that "the object's motion direction and the direction of the force are the same to produce acceleration", that is, the fan blade The direction of rotation is the same as the direction of the force (wind energy), so it has high efficacy and low cost. Moreover, the fan blade rotates horizontally during operation, and the RPM is kept below 25 rpm, so when the bird accidentally touches it by mistake, it is Throw away in a horizontal direction without death or ser...

Abstract

The integrated vertical shaft windmill includes wind direction indicator vane and at least one layer of frame supporting column which can be up-down plug-connected, and can be reinforced by means of steel rope, in the interior of the frame supporting column the fan blade frame is mounted, the driving shaft is vertically placed in the centre of the frame supporting column and fan blade frame, fixedly connected with the fan blade frame and is movably fit with the frame supporting column. It is characterized by that the wind direction indicator vane is successively connected with wind direction indication sensor and hydraulic propeller in the fan blade frame, its driving device is connected with at least a pair of small fan blade central shafts of vertical shaft, said upper and lower central shafts of the small fan blade are movably fit with fan blade frame.

Description

technical field [0001] The invention relates to an "integrated vertical axis windmill" which utilizes wind energy as power. Background technique [0002] In existing windmills utilizing wind energy, the direction in which the fan blades are placed is 90 degrees from the wind direction, which affects the generation of inertial energy, resulting in poor energy harvesting efficiency. Contents of the invention [0003] The purpose of the present invention is to provide an integrated vertical axis windmill, which utilizes wind energy as power, applies Newton's second kinematics principle, and designs the fan blades to be placed in the same direction as the wind direction, so that it can fully generate inertial energy and achieve high-efficiency "integrated body" Vertical axis windmill". [0004] The present invention is achieved in the following way: an integrated vertical axis windmill, including a wind direction indicator and at least one layer of frame pillars that can be p...
