Point symmetry is distributed in the both sides of jointed shaft 6, first connecting rod 21 and the second connecting rod 22 strong point on work platforms also symmetrical point
Cloth is in the both sides of jointed shaft, and then is possible to prevent lifting process to topple over because of centre-of gravity shift.
As shown in Figure 5 and Figure 6, in the present embodiment, pedestal 1 includes eight buoyancy tanks 11 and skirtboard 12, arranges in buoyancy tank 11
Having cavity volume, eight buoyancy tanks 11 are evenly arranged around same center in the water surface, fixing connection, buoyancy tank 11 between adjacent buoyancy tank 11
Bottom is connected with skirtboard 12, and in horizontal plane, buoyancy tank 11 forms isosceles trapezoidal structure, and the inward flange of eight buoyancy tanks 11 and outside
Edge forms octagon structure respectively, and the top surface inclination of buoyancy tank 11 is arranged, and the height of inward flange is greater than outward flange, floating
The passage 13 circulated for sea water or air it is provided with on the lateral wall of case 11.
The work progress of this offshore anemometer tower is: assembled by offshore anemometer tower on land, is then placed on marine,
Make whole offshore anemometer tower float on the surface, after being dragged to predetermined position in the way of towage, utilize water pump by sea water warp
Passage 13 pumps in cavity volume, and under gravity, offshore anemometer tower progressively sinks, and makes skirtboard 12 embed sea bed, final pedestal 1
It is supported on sea bed；After a place completes to survey wind task, the sea water in cavity volume is discharged, then by offshore anemometer tower towage
Carry out to another job site surveying wind operation.
By using the pedestal 1 of said structure, on the one hand the weight in offshore anemometer tower transportation, and base can be alleviated
Seat 1 itself can produce buoyancy, reduces the cost of transportation during towage, and offshore anemometer tower on the other hand can be made to repeat profit
With, reduce waste.Further, the top surface inclination of buoyancy tank 11 is arranged, and inward flange is higher than outward flange；When pedestal 1 meets with horizontal direction
Ocean current when washing away, the active force of ocean current forms a downward component on buoyancy tank 11 end face, and then increases pedestal 1 and sea bed
Frictional force, it is to avoid pedestal 1 movement under the washing away of ocean current.It addition, by arranging skirtboard 12, buoyancy tank 11 can be played necessarily
Protective effect.
In order to increase the combination dynamics of pedestal 1 and sea bed, promote the stability of offshore anemometer tower, alleviate ocean current to pedestal 1
Wash away, it is also possible to downwardly convex Embedded Division is set on skirtboard 12.
Certainly, pedestal 1 is not limited in above-mentioned a kind of structure；As it is shown in fig. 7, the second embodiment of the present utility model is then adopted
With the pedestal 1 of another structure, this pedestal 1 includes centre mount 14 and several elemental floating bodies 15, and elemental floating body 15 is by steel
Pipe is made, and the inner of elemental floating body 15 and centre mount 14 is fixing to be connected, and several elemental floating bodies 15 around centre mount 14 in putting
Penetrating shape to be evenly arranged, connect by third connecting rod 16 is fixing between the outer end of adjacent floating body unit 15, elemental floating body 15 is internal to be set
It is equipped with cavity volume.During installation, lifting type workbench is arranged on centre mount 14.
In other embodiments, the quantity of telescopic oil cylinder 4 and position can select as required, if its energy
Enough order about first connecting rod group and second connecting rod group stretches and shrinks；Telescopic oil cylinder 4 such as can be arranged in adjacent
Between two connecting rods 22, or telescopic oil cylinder 4 is arranged between the first connecting rod 21 and pedestal 1 of bottom position.
In other embodiments, the first connecting rod 21 being positioned at tip position can also by slideway 24 with work platforms 3 even
Connecing, the first connecting rod 21 being positioned at bottom position is connected with pedestal 1 also by slideway 24.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
