Abstract
The utility model relates to an automatic guiding device of an aerogenerator. A bar-shaped embossment for guiding is arranged on the housing of the aerogenerator; the side walls of the bar-shaped embossment are used for bearing the wind force, and the imbalanced stress on the two sides is used to rotate the generator, thus realizing the aim of guiding for the aerogenerator.
Description
Technical field
The utility model relates to a kind of wind generating unit, and especially a kind of auto-guider of wind-driven generator belongs to the wind energy applied technical field.
Background technique
Wind energy power is as eco-friendly power source, and its technology is constantly progressive, its more and more widely, especially for the purposes generating in lighting installation and remote short of electricity zone more widely; Because the direction of wind-force is often to change, traditional wind energy plant generally is that empennage or wind-driven generator outer installment guiding device are set on wind-driven generator, make the blade of wind-driven generator vertical substantially with maximum wind-force direction, with effective blowing area of the blade of abundant raising, improve the utilization ratio of wind-force; These guide structures, complex structure, cost height.
Summary of the invention
The utility model mainly is to solve existing in prior technology complex structure, technical problem that cost is high, and a kind of auto-guider of wind-driven generator is provided.The auto-guider of a kind of wind-driven generator of the utility model, it is provided with the strip bulge of guiding on the casing of wind-driven generator, it utilizes the sidewall of strip bulge to bear wind-force, thereby utilizes the uneven stressed generator body of actuating of its both sides to rotate the purpose that is reached for the wind-driven generator guiding.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of auto-guider of wind-driven generator, comprise the casing that is built-in with the blade generator coupled, the circumference that described casing closes on blade end is provided with several equally distributed, parallel substantially with blade rotation central direction strip bulges, and this strip bulge can make casing rotate around the shaft under the situation that the two side wind-engaging does not wait.Rotating shaft is the structure that wind-driven generator is fixing, and the casing of wind-driven generator can rotate around the axis under situation under the effect that is subjected to external force; Wind-force can be born in the two side of strip bulge, when wind-force comes to having when departing from more greatly with sidewall direction, wind-force produces active force at the sidewall of strip bulge, under the effect of this active force, casing rotates around the axis, and makes that the sidewall of strip bulge is stressed to be weakened gradually, until its sidewall with the wind comes from that direction is parallel substantially, the two side is stressed about the same, also just make the blowing area maximization in front of blade, even the maximization of also wind power utilization rate; This guide structure is simple and reasonable for structure, and guide effect is good, is easy to make, and cost is low.Rotating shaft as herein described is the rotatingshaft of casing under the effect of wind-engaging power, also can adopt other structures to replace, and has same technical purpose, belongs to simple technology conversion, still belongs within the protection domain of the present utility model.
As preferably, described strip bulge quantity is 2, is symmetrically set in the top and the bottom of casing.Strip bulge is located at the top and bottom of casing, that is unanimous on the whole with rotor shaft direction, improves the receptance to wind direction, makes guide effect better.
As preferably, the triangular in shape or rhombus of the side of described strip bulge or trapezoidal or top are the irregular shape of curve.Having blowing area preferably, and be easy to make.
As preferably, described strip bulge cross section and longitudinal section are that triangle or quadrilateral or sidewall are the irregular shape of curve.To guarantee enough intensity.Cross section as herein described and longitudinal section are direction shown in the drawings.
Be to improve the guidance quality of strip bulge wind-engaging, as preferably, described strip bulge is center of gravity and is partial to blade one side so that its sidewall with respect to the blowing area of blade near-end greater than far-end.This structure helps the blowing area at strip bulge sidewall rear portion greater than the front portion, has wind-engaging effect preferably.
As preferably, described strip bulge is the integrative-structure that casing stretches out and forms.This structure, simple in structure, assemble more simple and convenient.
As the equivalent of such scheme, described strip bulge is connected and fixed on casing by welding or bolt.The structure of this split production is easy to processing.
Based on further optimization steering capability, as preferably, described blade rotates when being subjected to from the wind-force of strip bulge end and drives the coupled generator for electricity generation that places in the casing.This structure avoids making because of the obstruct of blade the wind-engaging abatement of wind of strip bulge.
Therefore, the utlity model has characteristics rational in infrastructure, that steering capability is good, especially have beneficial effect simple in structure, low cost of manufacture.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the auto-guider of a kind of wind-driven generator of the utility model, as shown in Figure 1, it comprises the casing 4 that is built-in with blade 2 generator coupled, the circumference that casing 4 closes on blade 2 ends is provided with the strip bulge 3 parallel substantially with blade 2 center of rotation directions, and this strip bulge 3 can make casing 46 rotate around the shaft under the situation that the two side wind-engaging does not wait.
The integrative-structure that strip bulge 3 stretches out and forms for casing 4.Strip bulge 3 quantity are 2, are symmetrically set in the top and bottom of casing 4.
The side of strip bulge 3 triangular in shape, strip bulge 3 is center of gravity and is partial to blade 2 one sides, that is so that the leg-of-mutton top of its sidewall deflection blade end, make strip bulge 3 sidewalls with respect to the blowing area of blade 2 near-ends greater than far-end.
The cross section of strip bulge 3 and longitudinal section are that triangle or quadrilateral or sidewall are the irregular shape of curve.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also make some improvement and distortion, these also should be considered as belonging to protection domain of the present utility model.
