Detailed Description

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

1-4, a wind driven generator cabin type rain cover is mainly designed for a 3MW-141 wind driven generator cabin. The rainproof cloth cover comprises a first cuboid 1, the bottom of the first cuboid 1 is open, and an arch structure 2 and a second cuboid 3 are arranged above the first cuboid 1. The arch structure 2 is a half cylinder, and the bottom surface size of the arch structure 2 and the second cuboid 3 is smaller than the upper surface size of the first cuboid 1. Specifically, the size proportion of first cuboid 1, second cuboid 3 and domes 2 designs according to the size in cabin, guarantees that rain-proof cover can cover the cabin completely.

The contact part of the first cuboid 1 and the arch structure 2 and the contact part of the second cuboid 3 are communicated, and the contact part of the arch structure 2 and the second cuboid 3 is communicated.

The bottom of the first cuboid 1 is provided with a plurality of threading eyelets, and nylon ropes are arranged in the threading eyelets in a penetrating mode. Through taut nylon rope, tighten up rain-proof cover lower extreme opening, guarantee that rain-proof cover tightly laminates with the cabin shell, and then improve rain-proof cover's sealed effect. In this embodiment, the interval of the threading holes is 500 mm.

Be provided with four hoist and mount regions 4 on the rain-proof cover, hoist and mount region 4 three limits and be connected with rain-proof cover through waterproof double-end zip fastener. One side of the zipper is provided with a lap, and the width of the lap is not less than 40 mm. The arrangement of the nylon lapping edge covers the zipper, so that moisture can be effectively prevented from entering the inner side of the rainproof cover from the zipper. When the cabin is hoisted, the rain cover does not need to be taken off, and only the zipper of the hoisting area 4 needs to be opened and the lifting hook is fixed, so that the taking off and re-installation processes of the rain cover are omitted.

Five treading-prohibited areas 5 are further arranged on the rain cover. In the present embodiment, the no-stepping regions 5 are provided on the dome-shaped structures 2, and the no-stepping regions 5 are symmetrically distributed about the center lines of the dome-shaped structures 2. The size of the no-tread area 5 is 600mmx800mm, and five places are designed. The inside of the treading forbidding area is marked with the character of 'treading forbidding', the height of the character is 160mm, and the space between the characters is 190 mm.

The specific design position of the hoisting area 4 corresponds to the hoisting position of the nacelle, and the specific design position of the stepping prohibition area 5 corresponds to the position of the stepping prohibition area 5 of the nacelle.

When too big for preventing wind-force, the rain-proof cover is scraped away or is damaged, and rain-proof cover still disposes the windproof net, and the windproof net is installed at rain-proof cover surface, and windproof net bottom surpasss cabin bottom 400 mm. The windproof net is made of tire wires with the diameter not less than 7mm, and the mesh size is 250x250 mm. When the rain cover is installed, the windproof net tightly shines on the outer side of the rain cover and is fixed.

For the intensity at reinforcing rain-proof cover border, reduce the possibility that the border is torn, 1 bottom of cuboid turns over the department along and carries out double-deck reinforcement to do the processing of borduring. In this example, the width of the reinforcing region was 60 mm.

When the wind-proof cover is used, the rain-proof cover is reversely buckled on a cabin of a 3MW-141 wind driven generator, then the thickened nylon rope penetrates through a threading eyelet at the bottom of the first cuboid 1 to tighten and fix the rain-proof cover, and then the wind-proof net covers the rain-proof cover and is tightened. When the engine room is hoisted, the hoisting area 4 of the rain cover is opened, and then the hoisting hook is hung on the hoisting hole of the engine room. After the hoisting is finished, the zipper of the hoisting area 4 is closed.

In addition, each seam and lap joint of the rain cover must ensure 100% waterproofness. The rain cover material is low temperature resistant (-40 deg.C), acid and alkali resistant, folding resistant, dense and rain-proof canvas with RAL5003 (sapphire blue) color.

To sum up, the utility model discloses a rain-proof cover of above-mentioned structure, rain-proof cover close up the bottom through the nylon rope, guaranteed that rain-proof cover can tightly laminate on aerogenerator's cabin, and use the net of preventing wind further fixed rain-proof cover, make rain-proof cover more difficult quilt wind lift, and then make the leakproofness of rain-proof cover better. In addition, the rain-proof cover of this application sets up hoist and mount region and forbids trampling the region, makes rain-proof cover use more convenient.

The above are specific embodiments of the present invention, but the scope of protection of the present invention should not be limited thereto. Any changes or substitutions which can be easily conceived by those skilled in the art within the technical scope of the present invention are covered by the protection scope of the present invention, and therefore, the protection scope of the present invention is subject to the protection scope defined by the claims.
