Background technology
Huaneng Group Butuo second phase (mending you) wind power plant is located in Butuo County Bu Er townshiies and Huo Lie townshiies territorial scope, and project planning is built
If 25 single-machine capacity 2.0MW blower fan units, wherein limit a power 1.5MW, wind power plant total installation of generating capacity 49.5MW.Wind power plant
Using FD108C-000105HSM type wind power generating sets, all superstructures such as blower fan unit are relied on and are embedded in blower foundation in advance
Foundation ring is supported, and foundation ring radius 2.15m axial fan hubs centre-height is 85m, and unit and tower always weigh about 318.5t.
Wind-powered electricity generation site mean sea level 3100m, belongs to typical plateau climate area, and this area's sunshine is strong, and vegetation is covered
Lid rate is low, and day and night temperature is big, 7.3 DEG C of winter mean height temperature, -8.9 degrees Celsius of mean minimum temperature, to winter construction extremely not
Profit.Blower foundation is circular enlargement formula basis, basis extension position radius 9.9m, upper radius 3.5m, square foundation amount 593m3,
It is mass concrete.Limited by regional development, this area is sold without flyash, all 42.5 early-strengths of Binder Materials are common
Portland cement, through mix-design, blower foundation C35 concrete is 398kg per side's cement consumption, is computed, and concrete is hard
During change, the internal thermoae height of aquation easily produces crack.
Because most of current Sichuan province wind power plant be located at alpine region, such as Ganzi, Aba Prefecture, Goats in Liangshan Prefecture, such
Areas comprehensive situation is similar to Butuo County, and positioned at highlands, weather conditions are severe, and economy falls behind relatively, to concrete construction
Especially winter construction causes certain difficulty.
The content of the invention
The technical problems to be solved in the utility model is：There is provided a kind of blower foundation concrete heat-insulating device, it is to avoid blower fan
Mass of foundation is influenceed greatly by day and night temperature change and is produced thermal cracking, it is ensured that blower foundation is not invaded by outside cold current
Enter, it is ensured that the normal maintenance of concrete.
The technical solution of the utility model is as follows：
A kind of blower foundation concrete heat-insulating device, including it is covered in blower foundation circular enlargement part and upper face
Two-layer heat-preservation cotton quilt, wherein lower floor's cotton-wadded quilt are that water soaks cotton-wadded quilt, and blower foundation circular enlargement portion outboard is provided with heating and increases
Wet device, two-layer heat-preservation cotton is roof insulating by top, and roof insulating ceiling is followed successively by cotton-wadded quilt layer, geotechnological layer of cloth and steel pipe from outside to inside
Structure sheaf, steel-tube construction layer includes the first steel tube component, and the first steel tube component is hinged with the second steel tube component, and hinged place is connected with
Supporting steel pipe component, the supporting steel pipe component other end is placed on blower foundation circular enlargement part, is provided with roof insulating ceiling
Winch, winch is connected by steel wire rope with the free end of the second steel tube component.The setting of winch, facilitate roof insulating ventilation and
Temperature adjustment, steel wire rope can be reeled when temperature of shed is too high so that the second steel tube component around pin joint, turn over counterclockwise by (clockwise)
Turn, open roof insulating, you can ventilation and regulation temperature.Double-deck cotton-wadded quilt realizes the effect of accumulation of heat moisturizing.
The blower foundation circular enlargement part has been disposed radially temperature tube, and many temperature tubes can accurately grasp blower fan
The temperature conditions on basis, the ventilation of convenient adjustment roof insulating and heater.
The built-in fitting of support roof insulating is arranged at the blower foundation top, and built-in fitting is used for connecting upright pole, in support roof insulating
Heart position.
The free end of second steel tube component is placed on ground.
The heating and humidifying device include coal stove, and coal stove top is placed with open water container.
The utility model scene insulated curing device is totally carried out according to " regenerative process " principle, and general thought is summarised as " outward
Scaffolding, interior covering ".Because highlands outside climatic is changeable, often prominent to meet cold current, roof insulating is set up in outside, prevents prominent chance cold current
Caused temperature drastically declines.It is coal-fired in roof insulating to heat up, while being heated up water on coal stove distributes vapor, it is ensured that relative humidity exists
More than 95% (mock standard conserves interior humidity), temperature is in 5 DEG C~8 DEG C, roof insulating inner fan basis covering two-layer cotton
By (its middle and lower part cotton-wadded quilt watering moisturizing, curing concrete), heat storing and heat preserving maintenance is carried out.
The utility model had both avoided invasion of the outside cold current to blower foundation, between roof insulating internal simulation standard curing,
The heat that is distributed using concrete itself is incubated again, it is to avoid blower foundation quality is subject to the day and night temperature to change to be influenceed greatly
And producing thermal cracking, it is ensured that blower foundation is not invaded by outside cold current, it is ensured that the normal maintenance of concrete.
