Abstract
The utility model relates to a horizontal axis one axis and multi-grade windmill. The key technique of the windmill is one axis with multi-grade. Wind lead combinations higher than two-grade are installed on one horizontal axis. Secondly, every grade of the wind lead combination is provided with at least three wind leaves. The multi-grade combination of the windmill can be upper drift structure or lower drift structure. The mixing structure of upper drift and lower drift is the best. According to different demands, the windmill can be designed into cone ladder, wind leaf shapes of different grades, the number of wind leaves, anticlockwise rotation, clockwise rotation, and the like.
Description
Technical field
Multistage windmill of horizontal axis is the model utility machinery that effectively utilizes wind energy in the new energy field.
Background technique
The utility model is to improve to design on traditional single-stage horizontal axle windmill basis.Mainly overcome three big shortcomings of traditional single stage horizontal axis windmill: rotor diameter and area are big, and wind energy utilization is low; Wind turbine is load operation greatly; From increasing the power that the wind turbine diameter improves wind turbine, caused the technical barrier on producing and using merely.
Summary of the invention
The purpose of this utility model is the above-mentioned shortcoming that overcomes single-stage horizontal axle windmill, and provides a kind of horizontal axis a multistage windmill.
The technical solution of the utility model is:
1. the utility model is on same feathering axis, and the above fan blade combination of secondary at least is installed.
2. the utility model windmill, the fan blade number that each grade installed is 3 more than the fan blade at least, the fan blade number of each grade can equate, also can be designed to from 3 fan blades combinations of the upwind first order, the structural type that extremely following wind direction fan blade number of combinations at different levels increase progressively gradually.
3. the utility model windmill can be upwind structure or following wind direction structure, also can upwind and following wind direction mixed construction.
4. the utility model windmill can be a cylindrical structural, also can be from upwind, and the round gradient-structure that the diameter of extremely following wind direction wind wheels at different levels increases progressively gradually.
5. the utility model windmill can be to turn clockwise in design and installation, also can be to be rotated counterclockwise.
According to the technical measures that comprised more than the utility model windmill, the utlity model has five superior functionalitys:
1. under impeller was collected folk songs the condition that area equates, the utility model can improve the power of collecting folk songs of unit windmill in a large number, has both improved power, has saved spatial area again.
2. under the power prerequisite was collected folk songs in acquisition equally, cost of investment of the present utility model can significantly reduce.
3. the utility model is multistage because of the one axle, is collecting folk songs in servicely, and the advantage that power is big, operate steadily is arranged.
4. traditional horizontal axis single-stage windmill, the main path of raising single-machine capacity can only be to increase rotor diameter, gives and produces and the technical difficult problem of bringing, and high-power exploitation is restricted.The utility model has solved this problem from multilevel hierarchy.
5. traditional horizontal axis single-stage windmill because rotor diameter is big, fan blade is long, therefore, is resisted the strong wind ability, and the outage caused by strong wind phenomenon is often arranged, and wind speed utilizes narrow range, especially can not utilize the higher speed wind energy, is a big defective.The utility model effectively improves these defectives.
Description of drawings
Fig. 1 and Fig. 2 illustrate the no weathercock of equal 4 blades, upwind and following wind direction mixed construction of numbers of blade at different levels, the horizontal axis windmill of force 3 wind leaf combination.I in the icon, II, III represent the first order, the second level, the third level of the multistage windmill of horizontal axis respectively.
Fig. 3 and Fig. 4 are expressed as: from 3 fan blades of the upwind first order, and three grades of horizontal axis windmills that extremely following wind direction fan blade number of combinations at different levels increase progressively gradually.Numerical code expression among the figure: 3 fan blades of the 1-first order, partial 4 fan blades of 2-, 6 fan blades of the 3-third level, the combination of I-first order fan blade, the combination of II-second level fan blade, the combination of III-third level fan blade.
Fig. 5 and Figure 6 shows that: from the upwind first order, 4 blades, three grades of composite structures of increasing progressively gradually to wind direction rotor diameters at different levels down.
Embodiment
The working principle of the utility model and traditional horizontal axis single-stage windmill is the same with mounting type, and the pylon or the mast of windmill need to be installed, and the motor that matches with the windmill generating, power transmitting device etc.If be used for other machinery operation, then want concrete research and design.
Claims (4)
1. multistage windmill of a horizontal axis is characterized in that, on a concentric feathering axis, the above fan blade combination of secondary is installed at least.
2. multistage windmill of horizontal axis according to claim 1 is characterized in that, multistage windmill of horizontal axis, and the number of blade of each grade fan blade combination is three more than the fan blade at least.
3. multistage windmill of horizontal axis according to claim 1, it is characterized in that, the fan blade of a multistage windmill of horizontal axis makes up the positional structure of designed installation, there is upwind to install, following wind direction installation and upwind and following wind direction are all installed fan blade combination, these three kinds multistage fan blade stack mounting structural types altogether.
4. according to claim 1 or multistage windmill of 2 or 3 described horizontal axis, it is characterized in that the multistage windmill of horizontal axis turns clockwise and is rotated counterclockwise two kinds and turns to form.
