Description

Light-weight wind driven generator shell

Technical Field

The utility model belongs to the wind power generation machine field especially relates to a lightweight aerogenerator casing.

Background

Wind power is a renewable clean energy source which is widely applied, the wind energy resource in China is rich, a large amount of wind power generation equipment is widely applied to the ocean and the high mountain in China, but the wind power generation equipment is generally large, taking a 1500KW wind power generator which is commonly used in China as an example, the height of a tower barrel is about 70 meters, the diameter of a motor blade is 77 meters, and the weight of cabin equipment is about 22 tons, so the installation difficulty and the cost are very high, and technicians in the field hope to have a light-weight fan shell on the premise of ensuring the durability of the equipment, thereby the installation difficulty is reduced, and the installation cost is reduced.

Disclosure of Invention

An object of the utility model is to provide a lightweight aerogenerator casing solves the overweight problem of present aerogenerator casing.

In order to achieve the above purpose, the technical scheme of the utility model is that: a light-weight wind driven generator shell comprises end plates arranged at the front side and the rear side, four bases, a U-shaped coaming, two top beams and two motor fixing cylinders,

the motor fixing cylinder comprises a fixing plate and a cylinder ring, wherein the fixing plate is provided with a through hole in the middle, the cylinder ring corresponds to the through hole, the upper end of the fixing plate is fixedly connected with the top beam, the other part of the fixing plate is fixedly connected with the inner wall of the U-shaped bounding wall, the fixing plate is parallel to the end plates and is positioned between the two end plates.

The base is provided with a plurality of vertical supporting plates, and the upper ends of the vertical supporting plates are fixedly connected with the U-shaped coamings.

And a plurality of supporting plates are arranged in the concave groove beam.

The diameter of the cylinder ring is the same as that of the through hole.

The two motor fixing cylinders are arranged in parallel, and the cylinder ring of the motor fixing cylinder and the circle center of the circular opening of the end plate are positioned on the same axis.

The distance between the two motor fixing cylinders is larger than the distance between the motor fixing cylinder and the adjacent end plate.

The two top beams are arranged in parallel.

And a plurality of lacing wires are arranged on the U-shaped coaming along the axis direction.

The utility model discloses lightweight aerogenerator casing has mainly optimized shell structure for traditional aerogenerator casing, improves casing intensity, changes the tradition and utilizes the thinking that the casing intensity was reinforceed to heavy panel to realized utilizing lightweight panel to replace the traditional casing of heavy panel, furthest's reduction casing weight, thereby reduced aerogenerator's installation cost.

Detailed Description

As shown in fig. 1, the light-weight wind driven generator shell comprises end plates 1 arranged on the front side and the rear side, four bases 2, a U-shaped coaming 3, two top beams 4 and two motor fixing cylinders.

Be provided with circular opening on the end plate 1, end plate base both ends are upwards sunken to be formed with base mounting plane 11, base mounting plane 11 is higher than end plate bottom surface 12, 2 one end of base and 11 fixed connection of end plate base mounting plane, the other end is located between the two end plates, two back timber 4 parallel arrangement, both ends are 1 tops of end plate around the fixed connection respectively, 3 both sides of U type bounding wall respectively with front and back end plate 1 fixed connection, U type bounding wall top flushes with the end plate top, U type bounding wall, front and back end plate, the back timber has constituted aerogenerator casing jointly, it can reduce the end plate total area to improve base mounting plane, thereby reduce end plate weight.

The top of two walls of the U-shaped coaming 3 is provided with a concave groove beam 31, the opening of the concave groove beam is positioned on the surface of the U-shaped coaming, a plurality of supporting plates are arranged in the concave groove beam at equal intervals, and the strength of the side wall part of the machine shell can be effectively improved by utilizing the structure of the concave groove beam, so that the thickness of the side plate can be reduced, the weight of the machine shell can be further reduced, and meanwhile, the using amount of the coaming can be reduced and the weight of the machine shell can also be; in order to ensure the strength of the U-shaped coaming, a plurality of lacing wires can be arranged along the axial direction of the U-shaped coaming so as to further improve the strength of the coaming. Because the coaming has adopted U type structure, the lateral wall lower part is the arc structure, in order to guarantee to support intensity, sets up a plurality of backup pads and U type coaming fixed connection on the floor, guarantees casing intensity.

It should be noted that, the utility model discloses a can set up operating window, leak structures such as mouth of a river on the bounding wall according to traditional casing setting mode on the U type bounding wall, above-mentioned part sets up and is not the utility model discloses an innovation point place, detailed description is not carried out to this embodiment.

The motor fixing cylinder comprises a fixing plate 51 with a through hole in the middle and a cylinder ring 52 fixedly connected to the fixing plate, the cylinder ring 52 is the same as the diameter of the through hole, the corresponding arrangement is realized, the upper end of the fixing plate 51 is fixedly connected with a top beam 4, other parts are fixedly connected with the inner wall of the U-shaped coaming 3, the fixing plate 51 is parallel to the end plate 1, the fixing plate is positioned between the two end plates 1, the two motor fixing cylinders are arranged in parallel, the cylinder ring of the motor fixing cylinder and the circle center of the circular opening of the end plate are positioned on the same axis, the distance between the two motor fixing cylinders is larger than the distance between the motor fixing cylinder and the adjacent end.
