Description

A kind of wind-driven generator hood

Technical field

The utility model relates to wind generating technology, specifically is a kind of hood that is applicable to wind power generating set.

Background technique

Wind-driven generator is to be the dynamic power machine of mechanical energy with wind energy transformation; the structure of wind-driven generator mainly comprises shaft tower, blade, engine room cover, hubcap, backboard and generator; wherein, engine room cover and backboard and hubcap are assembled into an airtight space, are used to protect inner generator.Traditional engine room cover is because power is less, adopt cast steel material, material consumption is bigger, to wind load, snow load, add local load from heavy load and just seem too heavy, its structure normally engine room cover and hubcap is in composite structure in relative rotation, because the restriction of material property, engine room cover is as a whole usually; After the assembling of hubcap and foundry goods wheel hub finishes again with the piecemeal hubcap that is assembled into of air blade.

At present, because cost and technological progress, the power of wind-powered electricity generation unit trends towards maximizing, the volume of Dui Ying engine room cover, hubcap cover body also constantly becomes big with it, traditional overall structure is little because of its volume, aspect manufacturing, transportation, the installation greater advantage is being arranged, but is not suitable for the bigger wind-powered electricity generation unit of present power, therefore necessaryly develop a kind of novel cover body, satisfy the requirement of high power wind-powered electricity generation unit.

The model utility content

The purpose of this utility model is to provide a kind of wind-driven generator hood, to solve above-mentioned defective of the prior art.

For achieving the above object, the technical solution adopted in the utility model is a kind of wind-driven generator hood, comprises engine room cover, hubcap, backboard, and described engine room cover, hubcap, backboard constitute the inner wind-driven generator of confined space protection,

Described engine room cover is made of n slice, thin piece engine room cover; Described hubcap is made of m slice, thin piece hubcap, wherein, and 2≤n≤5 and/or 2≤m≤4.

Wherein, described backboard is made of one or two sub-backboard.

Wherein, the material of described wind-driven generator hood is a corrosion resistance glass fibre reinforced plastics.

Advantage of the present utility model and beneficial effect are to have increased burst quantity, reduce the production difficulty, and have reduced piece rate, save transport space, the convenient for assembly and favourable demoulding.
