Abstract

The present invention relates to a ring blade style wind wheel. A plurality of main blades(A1), each of which has a long strip shape, are uniformly distributed on and fixedly connected to a wheel disk (2); 2 to 4 connecting rings (B1, B2, B3, B4) are arranged on and fixedly connected with each of the main blades(A1); second ring blades(A2) which are uniformly distributed at intervals with the main blades (A1) are respectively fixed on and connected with the connecting rings (B1 to B4B), third ring blades(A3) which are uniformly distributed at intervals with the main blades (A1) and the second ring blades(A2) are respectively fixed on and connected with the connecting rings (B1 to B4B), and fourth ring blades (A4) which are uniformly distributed at intervals with the main blades (A1), the second ring blades(A2) and the third ring blades(A3) are respectively fixed on and connected with the connecting rings (B1 to B4B). The present invention has the advantages of simple manufacture and low production cost, the wind wheel has a larger blade surface on the whole, can fully play a role under weak wind, and is particularly suitable for windmills and wind power generating devices used in countryside families to use.

Description

Ring plate formula wind wheel
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.

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)
