Abstract

A kind of barrier-type vertical axis aerogenerator, comprise generator housing, be arranged on the main shaft in this generator housing, and a plurality of wind wheels that are connected with main shaft, on main shaft, be also connected with a barrier cover that covers wind wheel and can rotate around the spindle, barrier cover comprises cover body and the tail plate being connected with this cover body.This barrier-type vertical axis aerogenerator covers half of wind wheel windward side all the time by the barrier cover that is flexibly connected with main shaft and can rotates around the spindle, half wind wheel being covered on windward side is not subject to the thrust that wind applies it, and the wind wheel not covered produces the moment of rotation under the thrust of wind to main shaft, in the process of rotating at wind wheel, all the time the wind wheel that has half quantity is covered by barrier cover and is not subject to the thrust of extraneous wind, wind wheel is in the moment of arbitrary rotation, all only can produce power moment and can not produce resistance torque main shaft, realize zero resistance, improved vertical axis aerogenerator generating efficiency.

Description

A kind of barrier-type vertical axis aerogenerator

Technical field

The utility model relates to a kind of vertical axis aerogenerator, especially a kind of barrier-type vertical axis aerogenerator.

Background technique

Vertical axis aerogenerator project organization has adopted special air hole mechanics principle, the Placement of triangle vector method and the principle of directly driving type structure, the stressed of wind wheel mainly concentrated on wheel hub, so wind loading rating is stronger; The characteristic of this kind of design is also embodied in the impact of surrounding environment, and during running, noise free and electromagnetic interference be little etc., and feature makes Novel vertical axis wind turbine superiority very obvious.

Common resistance force type vertical shaft wind power generator is utilize the shape of wind wheel shape in direction windward asymmetric, cause resistance coefficient different, thereby produce the poor rotation that realizes generator shaft of thrust, as shown in Figure 1, for existing modal wind-cup type wind energy conversion system, because the resistance coefficient difference on wind wheel 6 windward sides causes the thrust F1>F2 of wind to wind wheel 6, resistance difference (F1-F2) has just produced the torque to wind wheel 6, in Fig. 1, F2 has played negative torque to the rotation of wind wheel 6, will inevitably offset to a certain extent the positive torque that F1 is original produced, F2 has played the effect of resistance with respect to F1, thereby reduced the main shaft rotational speed of vertical axis aerogenerator, affected generating efficiency.

Model utility content

The purpose of this utility model is in order to solve the existing defect of vertical axis aerogenerator in prior art, provides a kind of wind wheel is realized to zero resistance, the barrier-type vertical axis aerogenerator that generating efficiency is high substantially.

To achieve these goals, the technical solution adopted in the utility model is:

A barrier-type vertical axis aerogenerator, comprises generator housing, is arranged on the main shaft in this generator housing, and a plurality of wind wheel being connected with main shaft, is also connected with a barrier cover that covers wind wheel and can rotate around the spindle on described main shaft.

Above-mentioned a kind of barrier-type vertical axis aerogenerator, described barrier cover comprises cover body and the tail plate being connected with this cover body.

Above-mentioned a kind of barrier-type vertical axis aerogenerator, described cover body is semi-cylindrical shaped and covers all the time half of described a plurality of wind wheels windward side, and described tail plate is fish tail shape and extends towards the outside of main shaft.

Above-mentioned a kind of barrier-type vertical axis aerogenerator, described cover body is flexibly connected with described main shaft by connecting rod.

Above-mentioned a kind of barrier-type vertical axis aerogenerator, leaves gap between the rotation side face of the internal surface of described cover body and a plurality of wind wheels.

The beneficial effects of the utility model are: this barrier-type vertical axis aerogenerator covers half of wind wheel windward side all the time by the barrier cover that is flexibly connected with main shaft and can rotates around the spindle, half wind wheel being covered on windward side is not subject to the thrust that wind applies it, and the wind wheel not covered produces the moment of rotation under the thrust of wind to main shaft, in the process of rotating at wind wheel, all the time the wind wheel that has half quantity is covered by barrier cover and is not subject to the thrust of extraneous wind, wind wheel is in the moment of arbitrary rotation, all only can produce power moment and can not produce resistance torque main shaft, realize zero resistance, improved vertical axis aerogenerator generating efficiency.

Accompanying drawing explanation

Fig. 1 is traditional wind-cup type wind energy conversion system rough schematic;

Fig. 2 is plan view of the present utility model;

Fig. 3 is the utility model plan view.

Embodiment

For making that structure characteristic of the present utility model and the effect reached are had and further understand and be familiar with, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:

As shown in Figure 2 and Figure 3, a kind of barrier-type vertical axis aerogenerator, comprise generator housing, be arranged on the main shaft 1 in this generator housing, and a plurality of wind wheel 2 being connected with main shaft 1, on main shaft 1, be also connected with a barrier cover that covers wind wheel and can rotate around main shaft 1, barrier cover comprises cover body 3 and the tail plate 4 being connected with this cover body 3, wherein, cover body 3 is semi-cylindrical shaped and covers all the time half of a plurality of wind wheels 2 windward sides, and tail plate 4 is fish tail shape and extends towards the outside of main shaft 1.

In the utility model, cover body 3 is flexibly connected with main shaft 1 by connecting rod 5, for the ease of wind wheel 2, rotates, and between the internal surface of cover body 3 and the rotation side face of a plurality of wind wheel 2, leaves gap.

As Fig. 2, shown in Fig. 3, false wind is to blowing from left to right in the drawings, the thrust that tail plate 4 is subject to wind will inevitably turn to the right of main shaft 1 and parallel with flowing to of wind, certainly according to the transformation of wind direction, barrier cover also can be along with forwarding to, but barrier cover covers wind wheel 2 windward sides half all the time, half wind wheel 2 being covered on windward side is not subject to the thrust that wind applies it, and the wind wheel 2 not covered produces the moment of rotation to main shaft 1 under the thrust of wind, in the process of rotating at wind wheel 2, all the time the wind wheel 2 that has half quantity is covered by barrier cover and is not subject to the thrust of extraneous wind, wind wheel 2 is in the moment of arbitrary rotation, all only can produce power moment and can not produce resistance torque main shaft, realize zero resistance, improved vertical axis aerogenerator generating efficiency.

More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
