Description

A kind of cone cover type windmill

The utility model relates to a kind of windmill, particularly a kind of cone cover type windmill.

The windmill utilization is existing quite historical, its trace is from ancient times to the present all arranged, be used to draw water more, mills etc. are located, and employed blower fan form mostly is plane wind-engaging (common be three or multiple-blade form), it develops so far but still how only to improve on blade and installing angle, make it less windage to improve operation efficiency, but the effect that can improve is unsatisfactory, yet can use the wind-force size to calculate by wind speed and blowing area, and general blowing area is the face of blade gross area, not only be helpless to the wind-force utilization as for interlobate gap, and more can block blade rotation (windage), so its efficient is not high, windmill commonly used is for improving blowing area, lengthened vanes must be strengthened, often must be inserted into tens of meters changes footpath side's tool practicability, but but the other problem of can deriving, as must higher wind just rotating, the long frangibility of blade, cost is also high; Therefore, the windmill of this form is difficult to popularize, and especially doing small-sized use, as household, hot water heating, pressurized air etc., is difficult to especially promote.

The purpose of this utility model be for provide a kind of easy to use, cost is low, the cone cover type windmill that popularizes easily.

The utility model is realized by following technological scheme.Get ready and be subjected to wind apparatus, power switching device and support etc., being subjected to wind apparatus is to connect with an axle center to drive to power switching device, the pedestal frame below of power switching device then sleeve on support; Be subjected to wind apparatus by awl cover, revolve push wing, axle center and pole thereof etc. and constitute, the awl cover is with the tortuous tapered body of thin plate, revolving push wing then is made of oblique guide card and folding guide card, wherein tiltedly guide card is that even distribution vertical welding is fixed in the awl cover awl end and oblique center pointed cone, and the folding guide card is in 90 ° of awl bottom warpages or big slightly obtuse angle at oblique guide card, and be welded on the awl root edge, promptly constitute the cone cover type windmill.

Revolve push wing and settle and also can do a secant angle and be uniformly distributed on the awl cover, and tiltedly guide card with roll over guide card warpage place and can become a little arc round angle; The oblique guide card that revolves push wing on the awl cover is for becoming big arc-curved shape, and and becomes a suitable secant angle to arrange vertical solid welding with awl cover center.

The utility model is full cone superficies because of blowing area, its general each face of blade surface area of windmill is much more, wind-force can be given to the greatest extent and including in and in constantly blowing, more can increase its usefulness because of the utility model windage is little again, so when gentle breeze, can rotate, just can work done (inflating or generating in a small amount) when wind speed 1～2 meter per second in the actual test, practicability and use value have been improved greatly, the utility model is followed suffered wind-force and respectively revolves the awl wing and revolve toward outer rim and get rid of by awl point and the conical surface, make its strength be concentrated to the peripheral folding of each awl cover guide card, and this thrust is to the moment maximum of boring between sharp center (axle center), so can make it to bring into play maximum efficiency, more general windmill mean forced is distributed on each blade different fully, the utility model need not tail vane can adjust the weather side voluntarily, thereby reduced cost, reduced volume, easy to use, popularize easily, can be used as household, hot water heating, pressurized air etc.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is the utility model structural representation

Fig. 2 is the utility model cross-sectional view

Fig. 3 revolves the push wing structural representation for the utility model

Fig. 4 is the utility model awl cover structure schematic representation

Fig. 5 revolves another preferred embodiment figure of push wing for the utility model

Fig. 6 revolves the another preferred embodiment figure of push wing for the utility model

With reference to Fig. 1, get ready and be subjected to wind apparatus, power switching device and support etc., be subjected to wind apparatus by awl cover 10, revolve institutes such as push wing 11, axle center 13 and cradling piece thereof and constitute, axle center 13 reaches power switching device again, and promptly pedestal frame 14 and two

bearing bracket

15,16 thereof are passed in axle center 13, and a belt shaft 17 is also locked in 13 rears, axle center, drive to another belt pulley 19 on the crank rod 20 with a belt 18, crank rod 20 is rotated, and then promote the back plug 22 of cylinder 23, reach compressed-air actuated function; And the power switching device of axle center 13 back transmissions can be generator or other power plant, to cooperate various occasions required; Support for being with a plane bearing 25 and sleeve in axle sleeve 26 holes of brandreth 27 top center, can keep the front wind-engaging to support whole group mechanism and to make awl cover 10 for to weld fulcrum 24 below pedestal frame 14 on the axle automatically; Main feature of the present utility model is the awl cover 10 and the design of revolving push wing 11, and as shown in Figure 3, Figure 4, awl cover 10 is for to form with the thin plate complications, and its taper angle can be required and do selection according to each department wind-force size, is good with the obtuse angle greater than 90 ° generally; Revolving push wing 11 is to be made of oblique guide card 111 and folding guide card 112, and wherein tiltedly guide card 111 is fixed in the awl cover 10 awl end and oblique center pointed cones for even distribution vertical welding; And folding guide card 112 be at oblique guide card 111 in 90 ° of awl bottom warpages or big slightly obtuse angle and be welded on the awl root edge, it is spreadable to respectively revolving push wing 11 and push-jump awl cover 10 and interior axle center thereof to make wind-force blow on the pointed cone and the conical surface back; For to obtain the better thrust of revolving, revolve push wing 11 and also can become a little secant angle 1 to be uniformly distributed on the awl cover 10 as shown in Figure 5, and be to reduce flow-disturbing phenomenon that the right angle may produce again, then can form little arc round angle with folding guide card 112 warpage places at oblique guide card 111; Or as shown in Figure 6, the oblique guide card 111 that revolves push wing 11 is for becoming big arc-curved shape, and and becomes a suitable secant angle to arrange vertical solid welding with awl cover 10 centers, and the folding guide card 112 that its outer end links to each other as above is set forth in to bore 90 ° of bottom warpages or big slightly obtuse angle and be welded in and bores on the root edge.
