Abstract
The utility model discloses a gravity sail-unfurling windmill comprising a windmill support (3), a wheel spindle (2), a sail support (4) and a sail (6). The gravity sail-unfurling windmill is characterized in that the sail support (4) is fixed on the wheel spindle (2) and can rotate around the wheel spindle; the upper end of the sail (6) is fixed on the cross beam of the sail support (4); and the lower end of the sail is fixedly provided with a gravity rod (5). According to the utility model, the sail is unfurled and furled by use of gravity, so that the upper part and lower part of the sail are subjected to unbalance stress and consequently the wheel spindle rotates to supply power; and the gravity sail-unfurling windmill has the advantages of large design power, high efficiency and good economic benefit.
Description
Technical field
The utility model relates to a kind of equipment of Wind Power Utilization.
Background technique
No matter make a general survey of human exploration to Wind Power Utilization, be the large ship formula windmill of Holland in ancient times, and the still modern fan-shaped windmill of three leaves does not all have to solve the problem of efficiently utilizing wind energy.The particularly existing three leaf sector wind power generators that set up in a large number, because of its cost is high, economic benefit is low, is called to make a show by people widely to denounce.
Summary of the invention
The purpose of the utility model is to provide a kind of can efficiently utilize wind energy, and cost is low, the good in economic efficiency gravity windmill of lifting a sail.
In order to solve above-mentioned technical problem; The utility model is realized through following technological scheme: a kind of gravity windmill of lifting a sail; Comprise windmill support, wheel shaft, sail support, sail; It is characterized in that: the sail support is fixed on the wheel shaft and can rotates around wheel shaft, and the upper end of sail is fixed on the crossbeam of sail support, and a gravity rod is fixed in the sail lower end.
The utility model utilizes gravity sail to be opened and purse up, thereby sail receives force unbalance up and down, thereby make wheel shaft rotate power is provided, and has the advantage that design power is big, efficient is high, good in economic efficiency.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing and practical implementation instance the utility model is done further to set forth.
Can know from Fig. 1; The utility model comprises windmill support 3, wheel shaft 2, sail support 4, sail 6; It is characterized in that: sail support 4 is fixed on the wheel shaft 2 and can rotates around wheel shaft; The upper end of sail 6 is fixed on the crossbeam of sail support 4, and a gravity rod 5 is fixed in the sail lower end, is provided with a control position pearl 1 at two ends of gravity rod 5.
More than show and described basic principle of the utility model and the advantage of major character and the utility model; The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
