Problems solved by technology

Existing vertical axis wind generators: such as the patent No. 200910012160.7, the name of the invention is vertical axis wind generators, the disclosed technology has a low conversion rate of wind energy, and it cannot rotate due to its own weight at low wind speeds. In the case of work, if the wind is strong, there will be damage due to structural instability

Embodiment Construction

[0018] see figure 1 , the butterfly-shaped wind-receiving frame 1 is evenly distributed on the rotating sleeve 2, and the rotating sleeve is fixed on the shaft of the rotating sleeve; see figure 2 , the rotating sleeve shaft is vertically fixed on the top of the tower 3; the butterfly-shaped wind-receiving frame is fixed with a honeycomb horizontal flap frame 4; see Figure 3~4 , each polygon of the honeycomb horizontal flap frame has a limiting boss 5 and is fixed with a horizontal flap 6 through a small horizontal shaft 8 .

[0019] Six butterfly-shaped wind-receiving frames are evenly distributed on the rotating sleeve.

[0020] see figure 2 , the outer side of the butterfly-shaped wind-receiving frame is curved 9, which is a bionic structure.

[0021] A support truss 7 is fixed on the butterfly-shaped wind-receiving frame frame.

[0022] The supporting truss is a horizontal cantilever beam fixed on the rotating shaft, and an oblique support beam is fixed on the horiz...

Abstract

The invention provides a honeycomb flap resistance type vertical-axis wind generator. The honeycomb flap resistance type vertical-axis wind generator solves the problem that a pure resistance type vertical-axis generator is still at a small-size stage. The honeycomb flap resistance type vertical-axis wind generator comprises papilionaceous wind bearing frameworks, and is characterized in that the papilionaceous wind bearing frameworks are evenly distributed on a rotary sleeve, the rotary sleeve is fixedly arranged on a rotary sleeve shaft, and the rotary sleeve shaft is vertically and fixedly arranged on the upper portion of a tower; honeycomb type horizontal flap frameworks are fixedly arranged on the papilionaceous wind bearing frameworks, and each polygon of the honeycomb type horizontal flap frameworks is provided with a limiting boss and a horizontal flap in a fixing mode. The honeycomb flap resistance type vertical-axis wind generator has the advantages that multiple flaps solve the problems of jamming and dead points of a single flap caused by freezing and stiction caused by climate, environment and other factors, a domino effect will happen as long as a small number of flaps can work, and all the flaps are driven to work.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a resistance type vertical axis wind power generator using honeycomb flap blades. Background technique [0002] The technical route of vertical axis wind turbines can be divided into two types: lift-drag composite type and pure drag type. In terms of lift-drag composite vertical-axis power generation technology, MW-level units are already in the stage of industrial prototype testing, while pure drag Type vertical axis power generation is still in the small stage. Existing vertical axis wind generators: such as the patent No. 200910012160.7, the name of the invention is vertical axis wind generators, the disclosed technology has a low conversion rate of wind energy, and it cannot rotate due to its own weight at low wind speeds. In the case of work, if the wind is strong, damage will occur due to structural instability. The patent number is 200910132493.3, and the title of th...
