Abstract
The utility model provides a large-scaled wind and power engine room cover, belongs to a wind generating set used device and comprises an upper cover body and a lower cover body. The upper cover body and the lower cover body which are made by multi-directional glass fiber cloth are connected by inner flanges. Hollow reinforcement ribs are arranged on the internal surfaces of the upper cover body and the lower cover body. By changing the structure and connection mode of the wind and power engine room cover, the large-scaled wind and power engine room cover improves the mechanical intensity of the product, enhances aging-resistant and wind-load-resistant capacities, maximizes the cover body of the engine room cover, not only has light weight, high intensity and large bearing capacity, but also is economic and safe and is convenient to be installed, and is especially suitable to be used for the wind generating sets with more than 1.5 megawatts.
Description
Technical field
The utility model belongs to wind power generating set equipment, refers in particular to a kind of high electric motor power (more than 1.5 megawatts) wind power generating set large-scale wind electricity engine room cover.
Background technique
Existing wind-power engine room cover, divide small-sized and medium-sized two classes, by the reinforcing fiber hand pasting forming, this type of engine room cover only is applied to the following wind-powered electricity generation unit of 1 megawatt, little and setting height(from bottom) is low because of the volume of middle-size and small-size wind-powered electricity generation unit, less demanding to the engine room cover mechanical strength, but above its installing space of wind-powered electricity generation unit of 1.5 megawatts (is about 10m greatly, wide about 3.6 meters, high about 3.8 meters) and the big height of setting height(from bottom) (50-60 rice), this just requires the engine room cover compact overall structure, in light weight, mechanical strength, wind resistance carries, aging quality resistance is strong, long service life, therefore, the performance of the middle-size and small-size wind-power engine room cover that has of scene and the usage requirement that structure can not satisfy high electric motor power wind power generating set.In addition, the reinforcing fiber that is used to make this kind wind-power engine room cover be longitude and latitude two to cloth, the intensity of product is two-way, the resin glue amount uniformity of fiber is uncontrollable during hand pasting forming, everywhere the intensity inequality; The last lower cover assembling seam of wind-power engine room cover is a dock, also wants butt joint to carry out reprocessing during installation, and the more installation period that causes of installation procedure is long.
Summary of the invention
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, a kind of economy, safety, intensity height are provided, the large-scale wind electricity engine room cover that is applicable to the above wind-powered electricity generation unit of 1.5 megawatts easily is installed, main innovation is that with multidirectional glass fiber cloth be material, product all directions stress improves, and bulk strength strengthens; The last lower cover of wind-power engine room cover adopts flange to connect, with shell ribbing type structure with control engine room cover weight.Specifically implement like this: the large-scale wind electricity engine room cover, comprise upper outlet body, lower cover, it is characterized in that the upper outlet body that multidirectional glass fiber cloth is made is connected by inner flange with lower cover, all is equipped with hollow strengthening rib on the inner side surface of upper outlet body and lower cover.Because the wind-powered electricity generation unit is installed in the high-altitude, consider the load-bearing of whole unit, will want strict control to the weight of engine room cover, therefore adopt shell ribbing type structure with control engine room cover weight, engine room cover cover body thickness only is 7-8mm, also littler than middle-size and small-size engine room cover wall thickness (10mm), because engine room cover cabin bulk area is bigger, therefore cover body rigidity deficiency installs hollow strengthening rib on the cover body inner side surface of cabin, improve the rigidity of bulkhead, prevent the bulkhead distortion; Mode with inner flange connects lower cover, and is easy for installation, quick, and after the installation, the engine room cover profile be can't see the splicing flange, and this flange Connecting format can improve engine room cover overall appearance degree, and flange can be used as the horizontal strengthening rib of bulkhead simultaneously.Last lower cover is a material with multidirectional glass fiber cloth, because of all directions stress improves, bulk strength has also strengthened, select high tenacity simultaneously for use, the mechanical strength height, good heat resistance, the matrix resin of low-shrinkage, guarantee the mechanical strength of product body, during construction, adopt mixed construction technology, that is: injection+hand is stuck with paste the method for construction that combines, hand pasting forming is adopted in the processing that has overcome existing middle-size and small-size engine room cover usually, the uncontrollable deficiency of the resin glue amount uniformity of fiber, use injection method instead after, can guarantee the gel content uniformity of fiber, intensity is even everywhere to make product.
The all surface of the last lower cover of the utility model large-scale wind electricity engine room cover is curved-surface structure, it is that circular arc is along degree of slipping over that each face connects corner, this structure is with respect to the square structure of existing wind-power engine room cover cover body, greatly reduce the resistance of engine room cover surface to moving air, enhancing improves the wind resistance loading capability of engine room cover to the water conservancy diversion of air.
The utility model is by changing the structure and the Placement of wind-power engine room cover, improve the product mechanical strength, strengthen anti-aging, wind resistance loading capability, the engine room cover cover body is maximized, not only in light weight, intensity is high, bearing capacity is big, and economic security, installation are convenient, are specially adapted to the above wind-powered electricity generation unit of 1.5 megawatts.
