Abstract
A wind-driven wheel with vane rings is composed of main body, more main strip vanes fixed to main body, 2-4 connecting rings fixed to said main vanes, the second ring of vanes fixed to said connecting rings, the third ring of vanes alternative with the main and the second vanes, and the fourth ring of vanes alternative with all other vanes. Its advantages are simple structure and low cost.
Description
Technical field
What the present invention relates to is wind wheel apparatus, especially for the wind wheel of windmill, wind generating unit.
Background technique
The wind wheel of existing windmill or wind generating unit is to adopt three or more big blade to constitute, and each blade of wind wheel all is and the direct-connected blade of hub discs.The length of existing this each blade of wind wheel is very long, and volume is big, the blade shape complexity, the technical requirements height, the manufacture cost height, although each blade is very long, volume is bigger, but the blade blade face of wind wheel integral body is less, particularly blade outer end spacing is bigger, and wind wheel blade face on the whole is less, and the windward side is less, wind energy utilization is lower, can not play one's part to the full under less wind-force.Particularly can not fully be fit to rural households' windmill, wind-power electricity generation use.
Summary of the invention
The purpose of this invention is to provide a kind of simple and practically, make easyly, cost is low, is particularly suitable for the windmill that rural households use, the multiple-blade ring plate formula wind wheel of wind generating unit.
The present invention is by wheel shaft 1, front end at wheel shaft 1 is fixed with wheel disc 2, on wheel disc 2, evenly distribute and be fixedly connected with a plurality of long strip primary blades A1, opposed fixedly connected 2 the above connecting ring B that are provided with before and after on primary blades A1,2-4 connecting ring B1 for example, B2, B3, B4, each connecting ring B1, B2, B3, B4 is around axle center radially direct on primary blades A1, at connecting ring B1, B2, B3, the last fixedly connected respectively second ring blade A2 evenly spaced apart of B4B with each primary blades A1, with each primary blades A1 and the second ring blade A2 the 3rd ring blade A3 evenly spaced apart, with each primary blades A1, the second ring blade A2, the 3rd ring blade A3 is Fourth Ring blade A4 spaced apart evenly, forms mutliblade ring plate formula wind wheel.
The present invention is simple in structure, makes easyly, and cost of production is low, and wind wheel blade face on the whole is bigger, and the windward side is big, and wind energy utilization is higher, can play one's part to the full under less wind-force.Be particularly suitable for windmill, wind generating unit use that rural households use.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation.
Fig. 2 is the K-K sectional view of Fig. 1.
Embodiment
The present invention is by wheel shaft 1, front end at wheel shaft 1 is fixed with a wheel disc 2 that is made of double plate, on wheel disc 2, evenly distribute and be fixedly connected with a plurality of (being generally 6-8) long strip primary blades A1, at the opposed connection T-Ring B that is fixedly connected with more than 2 in front and back on the primary blades A1, shown in the accompanying drawing embodiment 2-4 connecting ring B1, B2, B3, B4, each connecting ring B1, B2, B3, B4 is around the axle center, and on primary blades A1, be spaced radial and distribute, at connecting ring B1, B2, B3, the last fixedly connected second ring blade A2 evenly spaced apart of B4 with each primary blades A1, at connecting ring B2, B3, last fixedly connected and each the primary blades A1 of B4, the 3rd ring blade A3 that the second ring blade A2 is evenly spaced apart, at connecting ring B3, last fixedly connected and each the primary blades A1 of B4, the second ring blade A2, the 3rd ring blade A3 is Fourth Ring blade A4 spaced apart evenly, connecting ring B more than 4 in this way, the distribution setting of its blade A is analogized therewith, forms the different multiple-blade of length, the equally distributed ring plate formula of multilayer wind wheel.
The present invention its each blade A1, A2, A3, A4 can be simple long strip flat plate, are connected with each connecting ring B1, B2, B3, B4 by welding manner.So process, make convenience easy to maintenance.The thickness of each blade A1, A2, A3, A4 should successively decrease.
Claims (2)
