Abstract
The utility model relates to a wind-force power generation device, which is characterized in that a plurality of small blades is assembled with a blade bracket through movable locks to form a large blade; at least four large blades are formed into a wind blade that is arranged on a bracket that is sleeved outside a central shaft; the central shaft is connected with a generator through a bearing and a gear unit to generate the electric power. The wind-force power generation device has the advantages of simple structure, convenient installation and low cost, and can be used for generating the electric power in the places with abundant wind-force resource such as the countryside, the plain, etc.
Description
Technical field
The utility model relates to a kind of wind generating unit, relates in particular to a kind of leafy wind generating unit.
Background technique
The equipment of current generating usefulness mostly is that waterpower, firepower etc. are used as power.These power generating equipment construction projects are big, and equipment is huge, expend many, only be suitable for the development and use of large corporation and unit, be unfavorable for scarcity of resources, area backward in economy and the development and utilization electric power in rural area are unfavorable for improving and promoting the development of local economy, must look for another way and method.
Summary of the invention
The purpose of this utility model is to provide a kind of can utilize wind resource, is combined into big blade with small leaf and makes impeller and produce power and drive diesel-electric leafy wind generating unit.
The utility model comprises small leaf, big blade, leaf frame, knot that can be undone by a pull, support and central shaft, and small leaf wherein is connected on the leaf frame with knot that can be undone by a pull separately and is connected into big blade, and this big blade at least can 4 be formed fan blades and is connected on the support.
Described small leaf is centroclinal downwards by required angle.
Central shaft connection wherein is placed in the support, and is connected generator by the bearing that is loaded in the bearing support with gear train.
The utility model adopts bearing support and bearing, and it is reduced friction, and rotating shaft is rotated flexibly, improves rotating speed, cuts down the consumption of energy; Use large and small vane group to become wind wheel, use knot that can be undone by a pull to connect small leaf, can adapt to the variation of blowing of different wind direction and wind velocities, be beneficial to switching, improve the utilization ratio of fan blade.
Description of drawings
Accompanying drawing is the utility model structural plan schematic representation.
Embodiment
Be illustrated in conjunction with the accompanying drawings and embodiments.
As figure, on wind field boundary ground, build up machine room 9 earlier, mounting bracket 6 refills upper bearing bracket 8 and bearing 7 thereof, loads onto gear train 10 again in machine room 9 it is connected with generator 11, and then, the central shaft 2 of packing into is placed in the support 6.When pneumatic, with knot that can be undone by a pull 4 be connected in big blade 1 that the small leaf 5 on the leaf frame 3 forms be subjected to wind-force blow and rotate, drive the central shafts 2 that are connected in the support 6 to rotate, drive to gear train 10 by bearing 7 and make its speed change drive generator for electricity generation.For small leaf 5 can be closed automatically, it is centroclinal downwards that each small leaf is all pressed required angle, promptly tilts to central axis direction.When wind during to the one side of closing, the generation power that just keeps out the wind, fan blade rotates, when wind during to another side, open because of the effect small leaf of knot that can be undone by a pull 4 and to ventilate, fan blade does not rotate, so big blade 1 rotates and drives central shaft and rotate and make gear rotate transmission and work toward a direction all the time.
Claims (3)
1, a kind of leafy wind generating unit, comprise small leaf, big blade, leaf frame, knot that can be undone by a pull, support and central shaft, it is characterized in that, small leaf wherein (5) is connected on the leaf frame (3) with knot that can be undone by a pull (4) separately and is connected into big blade (1), and this big blade (1) can be connected on the support (6) by 4 composition fan blades at least.
According to the described leafy wind generating unit of claim 1, it is characterized in that 2, described small leaf (5) is centroclinal by required angle downwards.
According to the described leafy wind generating unit of claim 1, it is characterized in that 3, central shaft wherein (2) connection is placed in the support (6), and is connected generator (11) by the bearing (7) that is loaded in the bearing support (8) with gear train (10).
