Abstract
The utility model relates to a rain -proof cover installation device of megawatt level wind -powered electricity generation blade, the device include limit for length's pole, perpendicular limit baffle, length limit baffle, spacing hole, fixed plate. Limit for length's pole left end upper portion is equipped with perpendicular limit baffle, its lower part is equipped with length limit baffle, limit for length's pole right -hand member is equipped with two rather than perpendicularly the fixed plate is equipped with two correspondences on this fixed plate spacing hole, and the hole heart line in two spacing holes with limit for length's pole is parallel. The utility model discloses the position that can avoid rain -proof cover to install on the wind -powered electricity generation blade effectively produces great deviation and mistake, exists when having avoided the wind -powered electricity generation blade with the installation of host computer wheel hub and interferes, and rain -proof cover mounted position is accurate, and in the time of can effectively avoiding raining, the rainwater gets into inside the host computer.
Description
Technical field
The utility model relates to megawatt wind-power blade manufacturing technology field, particularly relates to a kind of megawatt wind-power blade rain cover erecting device.
Background technique
On the earth can for human development and fossil energy be limited, and can not regenerate, but along with global industry process progressively expansion and accelerate, the demand of countries in the world to the energy sharply rises, and common coal, the oil and natural gas three macrofossil energy are day by day exhausted.
Wind energy, as a kind of clean renewable energy sources, is more and more subject to the attention of countries in the world.Wind-power electricity generation, for lack of water, short bunker and ungetable offshore islands, Pastoral Areas, mountain area and area, plateau, utilizes wind-power electricity generation with suiting measures to local conditions, very applicable, is well worth doing.
Wind power generating set comprises wind wheel, generator, containing blade, wheel hub, girth member etc. in wind wheel.Blade is parts that are the most basic in wind power generating set and most critical, its good design, and reliable quality and superior performance are the determinant factors ensureing that unit normal table runs.
Current vane manufacturing enterprise does not all give enough attention for the mounting point accuracy of rain cover, general direct use tape measure position, which needs repetitive measurement, strengthens the probability occurring deviation, and rain cover does not have frock to control, in installation process, there is certain distortion.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of megawatt wind-power blade rain cover erecting device, to solve the problem of positional deviation in rain cover installation process.
In order to solve the problem, a kind of megawatt wind-power blade rain cover erecting device described in the utility model, is characterized in that: this device comprises limit for length's bar, vertical postive stop baffle, length postive stop baffle, spacing hole, fixed plate; Described limit for length's bar left upper part is provided with described vertical postive stop baffle, and its underpart is provided with described length postive stop baffle; Described limit for length's bar right-hand member is provided with two perpendicular described fixed plates, and this fixed plate is provided with two corresponding described spacing holes, and the hole heart line of two spacing holes is parallel with described limit for length's bar.
The utility model compared with prior art has the following advantages:
The position that the utility model can avoid rain cover to be arranged on wind electricity blade effectively produces relatively large deviation and mistake, avoid to exist when wind electricity blade and main frame wheel hub are installed and interfere, rain cover mounting point is accurate, and when can effectively avoid rainy, rainwater enters main frame inside.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1, limit for length's bar, 2, vertical postive stop baffle, 3, length postive stop baffle, 4, spacing hole, 5, fixed plate.
Embodiment
A kind of megawatt wind-power blade rain cover erecting device as shown in Figure 1, this device comprises limit for length's bar 1, vertical postive stop baffle 2, length postive stop baffle 3, spacing hole 4, fixed plate 5.Limit for length's bar 1 left upper part is provided with vertical postive stop baffle 2, and its underpart is provided with length postive stop baffle 3; Limit for length's bar 1 right-hand member is provided with two perpendicular fixed plates 5, and this fixed plate 5 is provided with two corresponding spacing holes 4, and the hole heart line of two spacing holes 4 is parallel with limit for length's bar 1.
During use, spacing hole 4 on the utility model is enclosed within wind-power blade root end screw rod, hexagon nut is used to fix at end, install 7 according to identical mode at root of blade, then rain cover butt edge is adjacent to vertical postive stop baffle 2 of the present utility model, guarantee that rain cover entirety is all adjacent to vertical postive stop baffle 2 of the present utility model, finally use tension belt, rain cover is fixed, then takes off the utility model, complete one action.
