Abstract
The utility model discloses a wind-volume-self-adjustment type draught fan rectification cover. The wind-volume-self-adjustment type draught fan rectification cover is characterized by comprising a base. A hinge base is installed on the base, a swinging support is hinged to the hinge base, a rectification cover support is installed at the upper end of the swinging support, a rectification cover body is installed on the rectification cover support, a vertical shaft is installed at the lower end of the base and installed in a sleeve through a bearing, a flange is fixed outside the sleeve, a tail wing is installed on the base through a tail wing rod, a lead screw is hinged to the upper end of the swinging support and installed in a lead screw driver, and the lead screw driver is hinged to the base through a hinge. The wind-volume-self-adjustment type draught fan rectification cover has the advantages that the wind-volume-self-adjustment type draught fan rectification cover is used for a small axial-flow type wind driven generator, rectification compression is carried out on natural wind, the wind volume can be automatically adjusted according to the environment wind speed, when the environment wind speed is excessively high, the rectification compression degree of the natural wind is changed by changing positions of the rectification cover, and wind driven generator overvoltage, blade throwing damage and the like which are caused by overspeed operation of a draught fan can be avoided within a certain range.
Description
Technical field
The utility model relates to a kind of mechanical device, especially can automatically reconcile according to ambient wind velocity the self-regulated air quantity formula blower fan cowling of air quantity.
Background technique
Rectification Synergistic type wind-driven generator is that to utilize blower fan cowling to carry out rectification to natural wind concentrated, makes that natural wind is accelerated, rectification rear driving vane rotary.But the blower fan cowling using is at present all nonadjustable, when ambient wind velocity is too fast, blower fan cowling still accelerates wind, can make blower fan overspeed, and blower fan overspeed meeting causes the blade of wind-driven generator superpressure, blower fan to be got rid of evil idea etc.
Summary of the invention
For solving the above problems, the utility model provides a kind of self-regulated air quantity formula blower fan cowling.This self-regulated air quantity formula blower fan cowling can be reconciled automatically according to ambient wind velocity the concentrated intensity of wind.
The technological scheme that the utility model technical solution problem adopts is: invent a kind of self-regulated air quantity formula blower fan cowling, be characterized in, the rectification of self-regulated air quantity formula blower fan is covered with a base, hinge base is installed on base, a hinged swinging mounting on hinge base, cowling support is installed in swinging mounting upper end, on cowling support, cowling is installed, a vertical shaft is installed in base lower end, vertical shaft is arranged in a sleeve by bearing, sleeve is fixed a flange outward, on base, by empennage bar, empennage is installed, the hinged rhizoid thick stick in swinging mounting upper end, leading screw is arranged in a wire thilling driver, wire thilling driver is hinged on base by hinge.
The beneficial effects of the utility model are, the utility model is for small-size shaft streaming wind-driven generator, natural wind is carried out to rectification concentrated, can automatically reconcile air quantity according to ambient wind velocity, when ambient wind velocity is too fast, cowling changes the rectification concentrating degree to natural wind by changing position, can avoid within the specific limits the wind-driven generator superpressure, the blade that because of blower fan overspeed, cause to be got rid of evil idea etc.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing is the plan view of the present embodiment.
1 sleeve in figure, 2 flanges, 3 vertical shafts, 4 bases, 5 hinge bases, 6 swinging mountings, 7 cowling supports, 8 cowlings, 9 leading screws, 10 wire thilling drivers, 11 empennages, 12 wind-driven generators.
Embodiment
As shown in drawings, hinge base 5 is installed on base 4, a hinged swinging mounting 6 on hinge base 5, cowling support 7 is installed in swinging mounting 6 upper ends, cowling 8 is installed on cowling support 7, a vertical shaft 3 is installed in base 4 lower ends, vertical shaft 3 is arranged in sleeve 1 by bearing, sleeve 1 is outer fixes a flange 2, on base 4, by empennage bar, empennage 11 is installed, the hinged rhizoid thick stick 9 in swinging mounting 6 upper ends, leading screw 9 is arranged in a wire thilling driver 10, and wire thilling driver 10 is hinged on base 4 by hinge.
Flange 2 is provided with bolt hole, for being connected with wind-driven generator tower frame, vertical shaft 3 can freely rotate sleeve 1 is interior, empennage 11 can be according to ambient wind to driving base 4 rotations, make wind-driven generator 12 face all the time the direction of the wind comes from, wire thilling driver 10 can drive leading screw 9 stretch and can remain on diverse location, under the driving of leading screw 9, swinging mounting 6 can drive cowling support 7 and cowling 8 to swing on base 4, and is parked in a certain special position.Wind-driven generator 12 is provided with speed measurement device and controller, and controller is controlled wire thilling driver 10 according to the rotating speed of wind-driven generator 12, and it is flexible that wire thilling driver 10 is controlled leading screw 9, thereby reaches the object of controlling cowling 8 positions.When ambient wind velocity hour, cowling 8 is horizontal, cover wind-driven generator 12 completely, make its rectification concentrated effect to natural wind reach best, when environment wind-force excessive, when the rotating speed of wind-driven generator 12 surpasses specified value, wire thilling driver 10 drives leading screws 9 to make cowling 8 several angle that recedes, and environment wind-force strengthens again, when the rotating speed of wind-driven generator 12 improves again, cowling 8 continues to recede until leave wind-driven generator 12 completely, and now cowling 8 is completely inoperative.When environment wind-force reduces, the rotating speed of wind-driven generator 12 reduces, and cowling 8 is return gradually again, and environment wind-force subtracts the rotating speed of hour wind-driven generator 12 again and reduces, and the further return of cowling 8, until get back to horizontal position completely.Cowling 8 can be parked in diverse location according to environment wind-force, thereby reaches the object of the rotating speed of controlling wind-driven generator 12.
