Abstract

The utility model discloses a swirl vertical shaft windmill, which is composed of a bracket, a shaft and a wind wheel. The wind wheel which is composed of an upper supporting plate, a lower supporting plate and blades, the blades are fixed between the upper supporting plate and the lower supporting plate, and the middle of the upper supporting plate and the lower supporting plate is provided with the shaft which is arranged on the bracket. The utility model is characterized in that the number of the blades of the wind wheel is six to twelve, and the radian of the blades is 15 DEG to 80 DEG. Therefore, the utility model has the advantages of large wind acceptance area, high conversion of energy and high energy utilization rate.

Description

The rotary flow type upright shaft wind motor

The utility model relates to a kind of rotary flow type upright shaft wind motor.

At present, existing upright shaft wind motor is that the difference of utilizing blade to be in the moment of the axle bed mark different direction that both sides produced promotes the wind wheel rotation.Because its blade is few, radian is little, and the difference of two kinds of moments is little, so it is little to promote the moment of wind wheel rotation, utilization ratio of wind energy is not high.

The rotary flow type upright shaft wind motor that provides a kind of wind energy utilization high is provided the purpose of this utility model.

For achieving the above object, rotary flow type upright shaft wind motor of the present utility model is made up of support, axle, wind wheel, wind wheel is made up of upper bearing plate, lower support plate, fan blade again, fan blade is fixed between the upper and lower support plate, be provided with axle in the middle of the upper and lower support plate, this axle is installed on the support, and the blade that it is characterized in that wind wheel is the 6-12 sheet, and the radian of blade is the 15-80 degree.

After adopting such structure, make the blade of windward slope have half to have guide functions, one side most wind concentration to the forming of wind wheel with the making a concerted effort of value, and the anti-value that produces is very little with joint efforts, and moving air enters wind wheel twice generation successively with value with joint efforts, the difference of making a concerted effort of positive negative value increases, and improves the resultant moment of force when starting, and makes wind speed when 0.3 meter per second, just can start, its effective blowing area is big, and it is big to transform energy, the capacity usage ratio height.

Fig. 1 is the structural representation of the concrete a kind of embodiment of the utility model.

Rotary flow type upright shaft wind motor of the present utility model shown in Figure 1 is made up of support 1, axle 2, wind wheel 6, wind wheel 6 is again by upper and lower support plate 5,3, fan blade 4 is formed, fan blade 4 is fixed between the upper and lower support plate 5,3, be provided with axle 2 in the middle of the upper and lower support plate (5,3), this axle 2 is arranged on the support 1, and feature is that the blade 4 of wind wheel 6 is 8, and its radian is 28 degree.During work, because the blade of windward slope has half to have leading role, most wind concentration forms making a concerted effort with value to one side of wind wheel, and the anti-value that produces is very little with joint efforts, and moving air enters making a concerted effort of the same value of wind wheel twice generation successively, the difference of making a concerted effort of positive negative value increases, improved the moment when starting, so startability is good, tests according to the papery mini Mod, at wind speed during at 0.3 meter per second, just can start, its energy transformation ratio also just increases simultaneously, moreover the friction of blade and air is converted into the ability that wind wheel rotates equally, also reduce loss, increased energy utilization ratio.This rotary flow type upright shaft wind motor has saved steering system, so designs simplification, and is not high to the material requirements of making, relatively firmly, its applicability is also wide, except generating electricity, the power (replacing present sail) that also can be used as small-sized marine ships, so its development prospect is extensively wide.
