Abstract
A micro-resistance high-efficiency low wind-velocity wind mill with circular fan blade comprises a stand support, a fan blade, a bearing, a wind chamber, a wind helm, a rotating shaft connector and an outer sleeve. The utility model is characterized in that the rotating shaft connector is rotationally arranged on the stand support, the rotating shaft connector is connected with the outer sleeve, the periphery of the outer sleeve is connected with the fan blade, the outer edge of the fan blade is a circular arc wind catching groove in the same circumferential direction, the wind chamber is arranged outside a fan blade wheel and the wind chamber is rotationally connected with the stand support. the utility model has the advantages like: 360 degrees rotary wind chamber is employed without limit on wind direction, which ensures a small resistance, low starting wind speed and a high efficiency when the fan blade is whirled, therefore the utility model is widely applicable to wind power generating set, wind power rice grinding set, wind water pump set and wind threshing set.
Description
Technical field
The utility model belongs to a kind of wind energy conversion system wind mill equipment, the efficiently low wind speed windmill of the little resistance of particularly a kind of fan blade that circles round.
Background technique
Wind energy is inexhaustible renewable energy sources; countries in the world windmill technology is in very fast development at present; but windmill is produced when utilizing wind energy most effectively is no more than 60%; though China is the universally acknowledged the abundantest country of the air quantity amount of accumulateing; but maximum unfavorable factor is a skewness; there is 9,600,000 square kilometres region in China; but the area that the above wind power generating set of 1 megawatt can be installed only is 26% of China's land area; 74% the low wind speed zone of area genus is arranged; can utilize wind speed generally below 3 meter per seconds; Large-scale Wind Turbines and wind energy facility can not be installed; the existing water pumping of the wind-force acc power of China is too little in addition; therefore let alone exploitation wind-force thresher exactly because there is not a high-power low wind speed windmill; wind-force threshing machine and wind-force air bells exhauster.
The model utility content
The purpose of this utility model provides the efficiently low wind speed windmill of the little resistance of a kind of fan blade that circles round; output power is big, and the fan blade resistance that circles round is little, and starting wind velocity is low; the efficient height is applicable to wind power generating set, wind-force thresher group, water pumping of the wind-force unit, wind-force threshing unit.
The purpose of this utility model is achieved by the following technical solution: it comprises frame support body, fan blade, bearing, air compartment, wind rudder, running shaft connector, outer sleeve, it is characterized in that: running shaft connector rotating group is contained on the frame support body, the running shaft connector connects outer sleeve, the periphery of outer sleeve connects fan blade, the peripheral edge portion of fan blade is the groove that goes for a drive with the garden arc of circumferencial direction, air compartment is set outside fan blade, and air compartment is rotatably connected on the frame support body.
One side of above-mentioned air compartment is provided with intake grill, and a corresponding with it side is provided with the air-out narrow slit.
The utility model has the advantages that: structurally adopt rotatable 360 ° air compartment, be not limited by wind direction, guaranteed that fan blade resistance when circling round is little; starting wind velocity is low; the efficient height, applicable wind power generating set, wind-force thresher group, water pumping of the wind-force unit, wind-force threshing unit, widely applicable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that outer sleeve of the present utility model, running shaft connector are rotatably connected on schematic representation on the frame support body.
Embodiment
See Fig. 1,2, concrete structure of the present utility model is as follows: on frame support body 11 by bearing 8 outer sleeve 7 that is rotationally connected, outer sleeve 7 affixed running shaft connectors 9.Connect fan blade 4 in the periphery of outer sleeve 7, the peripheral edge portion of fan blade 4 is provided with garden arc with the circumferencial direction groove 3 that goes for a drive.Air compartment 1 is set outside fan blade, and air compartment 1 is rotatably connected on the frame support body 11 by bearing 10.Side at air compartment 1 is provided with intake grill 2, and a corresponding with it side is provided with multiple tracks air-out narrow slit 6 and wind rudder 5.
Working principle: under the effect of wind-force, fan blade rotates, and drives load by running shaft connector 9.When wind was arranged, the wind rudder 5 on the air compartment 1 made intake grill 2 nature of air compartment 1 towards the direction of the wind comes from, not wind-engaging to restriction.Because the peripheral edge portion of fan blade 4 is provided with garden arc with the circumferencial direction groove 3 that goes for a drive, both guaranteed the enough power of fan blade rotation, basic non-resistance when guaranteed again fan blade circles round.
Claims (2)
