Description
Technical field
The utility model belongs to wind power engineering field, and in particular to a kind of hollow type Wind turbines base that ring beam is arranged
Plinth.
Background technique
China's wind power foundation mainly uses reinforced concrete spread foundation at present, generallys use anchor bolt structure for blower
Basis is connect with tower.But with the fast development of China's wind-powered electricity generation industry, China's wind power generating set is intended to high-power at present
Change and altitude development, prestressed concrete-steel cylinder hybrid wind power generation pylon are able to satisfy large-scale wind electricity machine unit hub due to it
The requirement of height and rigidity, obtains extensive concern in wind-powered electricity generation field.Traditional anchor bolts formula basis resistance to capsizing is insufficient, basis
With the globality poor of tower, the case where being likely to occur basic Inclining destruction in extreme operating condition；In addition, this type of attachment is in week
The effect of phase property environmental load is lower to be easy to loosen, and results even in the fatigue rupture of anchor bolt structure, is unable to satisfy Wind turbines to big
The requirement of type and altitude development.
Utility model content
The purpose of this utility model is in view of the above problems, to provide a kind of reasonable in design, resistance to capsizing
By force, the Wind turbines spread foundation being connected firmly is, it can be achieved that high-power wind turbine crew base and the reasonable of pylon are fastenedly connected.For
This, the utility model uses following technical scheme:
A kind of hollow type Wind turbines basis that ring beam is set, it is characterised in that: including ring beam, spread foundation plate, bottom
Plate, concrete foundation bed course, upper sealing plate, annular haunch, prestress wire, the prestress wire are used for pylon and wind
Electric crew base is connected；
The hollow type Wind turbines foundation structure is followed successively by concrete foundation bed course, lower plate, extension base from the bottom to top
Plinth plate, ring beam, upper sealing plate are located at the top on the basis and are connected with ring beam；Pass through annular haunch and concrete towers at the top of ring beam
Cylinder is connected；
The inside on the basis is equipped with " convex " shape cavity, and upper sealing plate is arranged into people's access opening.
Further, it is in hollow disc shape that the basis is whole.
Further, hollow type Wind turbines basis, in ring beam internal reservation steel strand wires poling, and pre-buried steel strand wires
Lower anchor slab；
Further, the axis vertical take-off of lower anchor slab and steel strand wires, after tower hoisting is in place, by steel strand wires by pylon and base
Plinth is connected, and the cavity inside on basis implements tensioning preload to steel strand wires, and passes through tapered end for steel strand anchoring to ring beam
Bottom.
The beneficial effects of the utility model are:
(1) the utility model proposes a kind of setting ring beam hollow type Wind turbines basis, it is reasonable in design, anti-
Ability of toppling is strong, is connected firmly, it can be achieved that high-power wind turbine crew base and the reasonable of pylon are fastenedly connected.
(2) pylon and blower foundation are connected by prestress wire component, tower frame for wind generating set can be made generally in pre-
Pressure condition greatly improves tensile strength, resistance to capsizing and the stability of tower.
(3) basic construction is convenient for setting cavity, so as to the stretch-draw anchor of steel strand wires, to effectively prevent passing through tower
Tensioning bring high altitude operation risk in top is also convenient for the operation such as subsequent supplement tensioning of equipment O&M, steel strand wires.
Detailed description of the invention
Fig. 1 is the fan foundation structure elevation of the utility model.
Fig. 2 is the fan foundation structure top view of the utility model.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Fig. 1 ~ Fig. 2, a kind of hollow type Wind turbines basis that ring beam is set, including ring beam 1, spread foundation plate 2,
Lower plate 3, concrete foundation bed course 11, upper sealing plate 4, haunch 12, prestress wire 6, lower anchor slab 9 and tapered end 7, the blower
It is basic whole in hollow disc shape."convex" shaped cavity is set in the blower foundation, on the one hand convenient for equipment placement and artificial fortune
Dimension, on the other hand convenient for the stretch-draw anchor of steel strand wires 6 to effectively prevent through tower top tensioning bring high altitude operation
Risk.
The hollow type Wind turbines basis of the setting ring beam is constructed using cast-in-place mode, and strength grade of concrete exists
Between C40 ~ C45, foundation bottom is laid with concrete foundation bed course 11, and spread foundation plate 2 is in trapezoidal shape, is guaranteeing underlying strength
Under the premise of increase earthing amount, promote the resistance to capsizing of tower frame for wind generating set.Basic ring beam internal reservation steel strand wires poling 8, and
Pre-buried steel strand wires cast anchor plate 9, and lower anchor slab is rectangular steel plates, guarantee the axis vertical take-off of anchor slab 9 and steel strand wires when pre-buried.Upper sealing plate 4
Circular hole is arranged into people channel 10 in center, enters basic cavity inside convenient for personnel.
Concrete tower 5 passes through annular haunch 12 and is connected with basic ring beam 1；It, will by steel strand wires 6 after tower hoisting is in place
Pylon is connected with basis, implements tensioning preload to steel strand wires in basic cavity inside, by tapered end 7 by steel strand anchoring to basis
On the lower anchor slab 9 of ring beam bottom.By prestress wire 6 to structure stretch-draw anchor after so that tower frame for wind generating set is integrally located
In preloading condition, tensile strength, resistance to capsizing and the stability of tower are greatly improved.
Above embodiments are only a kind of more excellent technical solution of the utility model, it will be understood by those of skill in the art that
In the case where not departing from the principles of the present invention and essential situation can in embodiment technical solution or parameter modify or
Person's replacement, should be covered within the scope of the utility model.
