Abstract
A sand wind-resisting blade for a wind generating set solves the problem that the existing blade is easy to wear. The sand wind-resisting blade comprises a blade body made of composite materials, and is characterized in that a wear-resisting layer is attached on the surface from the middle part of the blade body to the windward side of a blade tip. The wear-resisting layer is fixed on the blade body in an adhering or coating manner. In the utility model, according to the part of the blade easy to be worn, the wear-resisting layer is additionally arranged on the key part of the blade, but not on the whole part of the blade, so that the wearing damage on the blade due to the wind sand is reduced to the minimum degree, and simultaneously the manufacturing cost is lowered to the maximum degree. After the wear-resisting layer is worn, the blade is repaired by replacing or repairing the wear-resisting layer, thus increasing the wear-resisting property of the blade.
Description
Technical field
The utility model relates to a kind of blade of large-scale wind driven generator, specifically a kind of wind generator set blade of anti-the dust storm.
Background technique
Existing fan blade generally is to use glass fiber compound material to make, it have in light weight, intensity is high, corrosion-resistant, electrical insulation capability good, heat transfer is slow, good, the anti-instantaneous superhigh temperature performance of thermal insulation is good and painted easily, can be through characteristics such as electromagnetic waves.In addition, have experiment showed, when the content of glass fibre in the material 15% when above, its wear-resisting property reaches best, the fiber of wear surface and fiber are appeared and have obviously been improved the wear resistance of glass fibre reinforced plastics.But because environment is abominable, and dust storm intensity is very big, and contain hard particles such as sandstone in the dust storm in the NORTHWEST CHINA Desert Area, these particles still can cause certain wearing and tearing to the blade of wind-driven generator, cause descend the working life of blade.
Laboratory data shows that the main abrading section of blade is terminal windward side, and this is directly to accept the dust storm impact owing to the linear velocity of vane tip is higher with the windward side to cause.So crucial wear resistance that is to improve the blade end windward side.
The model utility content
The purpose of this utility model is to provide a kind of wind generator set blade of anti-the dust storm, by setting up the wearing layer of special substance at key position, dust storm is dropped to minimum degree to the wear damage of blade, farthest reduces manufacture cost simultaneously.
The technical scheme in the invention for solving the technical problem is: a kind of wind generator set blade of anti-the dust storm comprises it is characterized in that the blade body of composite that described blade body middle part to the top layer, windward side of blade tip is with wearing layer.
Described wearing layer is fixed on the blade body by bonding way.
Described wearing layer is arranged on the blade body by coating method.
The beneficial effects of the utility model are: at blade position easy to wear, at the key position of blade rather than all set up wearing layer, dust storm is dropped to minimum degree to the wear damage of blade, farthest reduce manufacture cost simultaneously.After treating the wearing layer wearing and tearing, can repair blade, increase the wear resistance of blade by the mode of changing or repairing wearing layer.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the partial enlarged drawing of A-A section among Fig. 1;
Among the figure: 1 blade body, 2 wearing layers.
Embodiment
As shown in Figure 1 and Figure 2, a kind of wear-resisting blade of wind-driven generator comprises elongated blade body 1, and blade body uses glass fiber compound material to make.Blade body 1 middle part to the top layer, windward side of blade tip is with wearing layer 2, and this wearing layer 2 is by bonding or be fixed on the blade body 1 by the mode that applies, and this high-abrasive material is made by special wear-resisting macromolecular material.
Described blade windward side is meant the face in face of wind direction of blade when the normal operating condition lower blade is relative with wind direction.
Owing to only have additional wearing layer at the anti abrasive position of blade, cost increases few, and the thickness of wearing layer can be determined according to the concrete condition at each position of blade simultaneously.Normally in service, the sandstone in the wind can at first impact wearing layer, and wearing layer is impacted, and the wearing layer wearing and tearing are easy to repair or change.Make wind power plant become possibility in the utilization of desert area.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
