Description

Buried cartridge type wind driven generator base structure
Technical field
The utility model relates to a kind of wind driven generator base structure, especially a kind of buried cartridge type wind driven generator base structure.Be applicable to land wind driven generator base structure treatment.
Background technology
Energy scarcity and global warming are world today's problems the most deeply concerned; Wind energy is as a kind of reproducible clean energy resource; Huge with its amount of accumulateing, distribute extensively, advantage such as pollutions not, receive the increasing attention in countries in the world, accelerate to develop the common recognition that wind energy has become global energy circle.Wind energy is inexhaustible.In the epoch of stressing sustainable development, protection environment, wind-powered electricity generation has become general welcome clean energy resource.
In China, the wind-power electricity generation industry is an emerging industry.Last century, the eighties rose, and China's introduction of foreign technology is Construction of Wind farm at home progressively.After 2000,, domestic wind-power electricity generation industry is developed rapidly because country encourages the development and utilization to regenerative resource.
Up to the present, China in the Inner Mongol, Gansu, Hebei and the coastal region in east China built up large quantities of land wind energy turbine set.Land wind electric field blower foundation generally adopts spread footing, pile foundation, anchor pole basis, but along with the extensive development of wind-powered electricity generation industry, and land resources is nervous, day by day manifest with the problem such as shield of giving of local other industries.
Summary of the invention
The technical problem that the utility model will solve is: to the problem of above-mentioned existence; A kind of buried cartridge type wind driven generator base structure that can be applicable to various geological conditionss such as beach, Plain and mountain region is provided; Has good bending rigidity; And can well save Reinforced Concrete Materials, and be that a kind of floor space is little, safe and reliable, construction is convenient, the novel wind generator basis pattern of economic environmental protection.
The technical scheme that the utility model adopted is: buried cartridge type wind driven generator base structure; It is characterized in that: the buried cylindrical structure that comprises the hollow reverse frustoconic; This buried cylindrical structure has barrel and tube chassis, along circumference one circle is set at the barrel top and regulates bolt assembly.
Radially be some dishes of radial even layout strutbeam at the top of buried cylindrical structure.
Said adjusting bolt assembly is made up of screw rod, anchoring steel disc and detachable steel loop, and the screw rod of band anchoring steel disc is pre-buried inner in barrel, and the screw rod top is fixed by the detachable steel loop that has two circle bolts hole.
Said dish strutbeam is 3 ~ 5.
The beneficial effect of the utility model is: (1) blower foundation is a special construction by the stressed generation huge bending moment of large eccentricity.Different by vertical drag balance blower fan huge bending moment with conventional blower foundation (spread footing), buried bucket foundation is main horizontal drag balance blower fan huge bending moment by the buried soil body, has given full play to the horizontal force drag of deep foundation; (2) employing dish strutbeam, the dish strutbeam can provide very big horizontal force near basic ground, be used to resist moment of flexure and the horizontal force that blower fan is passed to the basis; (3) adopt buried cartridge type blower foundation, compare floor space with other blower foundations and reduce more than 50%, the protection limited land resources; (4) adopt buried cartridge type blower foundation, compare the base concrete amount with conventional spread footing and can reduce more than 30%, the reinforcing bar amount can reduce more than 70%; (5) adopt buried cartridge type blower foundation, compare face of land excavation area and excavation backfill amount with other blower foundations still less, reduce the ecosystem environment damage; (6) adopt buried cartridge type blower foundation, less or need not drive piles in the relatively poor area piling of grounds such as weak soil; (7) adopt buried cartridge type blower foundation, simple in structure, assembling reinforcement, formwork erection such as build at easy construction; (8) adopt buried cartridge type blower foundation, between blower foundation and tower tube, adopt bolt to be connected, do not need expensive steel discharge ring, bolt connects relative discharge ring and connects stressed more evenly, and connecting bolt applies barrel prestressing force, and connecting fastening force, to be difficult for pine slow.(9) adopt buried cartridge type blower foundation, pre-buried cable conduit path is short, and cable no longer passes through long pipeline, and cable laying is comparatively convenient.
Description of drawings
Fig. 1 is the vertical view of the utility model.
Fig. 2 is the sectional drawing of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2, present embodiment is the buried cartridge type wind driven generator base structure that steel concrete is built, and has the buried cylindrical structure 1 of hollow reverse frustoconic, and said buried cylindrical structure 1 comprises barrel 4 and tube chassis 5, and barrel surrounds a hole 6 with the tube chassis.This routine buried cylindrical structure 1 top radially is 4 dishes of radial even layout strutbeam 2.Said dish strutbeam 2 calculates according to the geological condition of construction environment and determines whether the quantity of arranging and arranging.
Barrel 4 end faces are provided with a circle along circumference and regulate bolt assembly 3; Said adjusting bolt assembly 3 is made up of screw rod 7, anchoring steel disc 8 and detachable steel loop 9; The screw rod 7 of band anchoring steel disc 8 is pre-buried in barrel 4; Screw rod 7 tops are fixing with the detachable steel loop that has two circle bolts hole 9, by the time buried cylindrical structure 1 end face concrete reaches certain intensity, detachable steel loop 9 dismantled so that the recycling steel loop; With prestressing force screw rod 7 is connected with the blower fan tower barrel flange, connects the space and fill and lead up, be in the milk and expect to need to adopt low void content, hang down the material that contraction, high-intensity cement based or epoxy radicals etc. are easy to construct with grouting.
It is suitable that said screw rod 7 exposes barrel 4 end face length, is convenient to connect the coxopodite tower drum flange, and the quantity of screw rod 7 should be consistent with coxopodite tower drum flange and detachable steel loop 9 upper bolt holes.
The degree of depth of said buried cylindrical structure 1 is adjusted according to geology and blower fan load; Dish strutbeam 2 can be according to prevailing wind direction along blower foundation center adjustment position, and dish strutbeam 2 is tied up muscle with buried cylindrical structure 1 and built, and whether tep reel strutbeam 2 calculates according to geological condition blower foundation decides.The tube hole that buried cylindrical structure 1 hollow part forms is used to pass through the outlet cable of wind power generating set, and fills with soil.
