Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail: Fig. 1 is the front section view on the offshore wind generating basis with down inserting type honeycomb structure chassis, Fig. 2 is that the first of Figure 1A-A sectional view executes example, Fig. 3 is that the second of Figure 1A-A sectional view executes example, Fig. 4 is that the first of Figure 1B-B sectional view executes example, and Fig. 5 is that the second of Figure 1B-B sectional view executes example.
As can be seen from Figure, there is weight and the load of the base support wind-driven generator 1 of the above-water wind generator of large area chassis and many pillar constructions, wind-driven generator 1 can have various different capacity, different structure and weight, and the present invention is specially adapted to the large high-power wind-driven generator be positioned on weak soil basis, shallow sea of bulking value.
The basis of wind-driven generator comprises basic top column 4, basic infrastructure chassis 6, a plurality of support spud pile 11.
Basic infrastructure chassis 6 is positioned at bottom, comprises bottom chassis upper flat plate 7, bottom chassis honeycomb structure vertical wall 8, a plurality of support fix stake holes 10.Basic infrastructure chassis 6 is flat a plurality of honeycomb structure chassis of lower opening back-off, and insert below mud face, seabed, the lower plane of bottom chassis upper flat plate 7 contacts with mud face, seabed, seabed mud surface bearing bottom chassis upper flat plate 7.Bottom chassis upper flat plate 7 and bottom chassis honeycomb structure vertical wall 8 form strength and stiffness all well honeycomb structure chassis, the area on flat basic infrastructure chassis 6 is larger, form wide shallow dark foundation bed structure, basic infrastructure chassis 6 is by the impact less than wave, because bearing area is large, can bear larger turning over load, the silt wherein surrounded has larger quality, make offshore wind generating have lateral stability, be firmly fixed on mud face, seabed.
A plurality of supports of vertical direction are fixed stake holes 10 and are uniformly distributed around chassis, portion 6 under the foundation, support in fixing stake holes 10 to have and support spud pile 11, support spud pile 11 and basic infrastructure chassis 6 connect as one, support spud pile 11 and have larger distribution area, larger support force distance can be formed, support the bearing layer that spud pile 11 squeezes into deep, seabed, can well bear transverse direction and vertical load, make it can not sedimentation downwards and waving, by basic infrastructure chassis, firmly supporting and fixing is at sea, the attack of storm tide or typhoon can be resisted, be applicable to the area of the attack being often subject to strong storm surge or typhoon, make the support wind-driven generator that basis energy is stable.
The top supporting fixing stake holes 10 has to be closed the support spud pile supporting spud pile 11 and to bind block 9, and there is the support spud pile pointed cone 12 of convenient piling the lower end supporting spud pile 11.
Top, basis column 4 is positioned at basic top, for open column shape, offshore wind generating 1 is installed in top, offshore wind generating 1 wind-driven generator fixed screw 2 is fixed, top, basis column 4 comprises top column top platform 3, the top stud wall of column, the transverse direction increasing basic top column strength and vertical a plurality of tops column reinforcing rib 5, top column reinforcing rib 5 makes basic top column have high intensity and rigidity, and the height of top column top platform 3 is higher than climax water level.Top, basis column major part is arranged in seawater, because diameter is less, little by wave impact area, reduces the lateral impact forces of wave, can well supporting wind power generation machine 1.
Top, basis column 4, basic infrastructure chassis 6, the fixing stake holes 10 of support make one, form overall structure.
When using Reinforced Concrete Materials to make wind driven generator base, gene basis weight is large, marine transportation and installation difficulty, chassis, its underpart, basic infrastructure chassis 6 honeycomb structure vertical wall 8 and the bottom chassis upper flat plate 7 of back-off form a plurality of enclosure space, can occluded air, can form buoyancy, basic infrastructure chassis makes by land, can carry out transportation by driving at sea after lower water, transportation by driving can solve volume weight great basic infrastructure chassis marine transportation difficulty.Basic infrastructure chassis is transported to installation site, can sink by nature after deflating.Then continue the air extracting enclosure space out, form negative pressure within the enclosed space, negative pressure makes bottom chassis be pressed into below mud face, seabed.
Basic infrastructure chassis 6 is divided into the enclosure space of multiple diverse location by bottom chassis honeycomb structure vertical wall, different negative pressure is formed in the space of diverse location, make the negative pressure of basic infrastructure chassis 6 diverse location different, in order to control the deflection of basic infrastructure chassis all directions, accurately carry out leveling, make basic infrastructure chassis that the top platform maintenance level of offshore wind generating is installed, ensure offshore wind generating central axis, guarantee the installation quality of offshore wind generating.
Fig. 2 is that the first of Figure 1A-A sectional view executes example, represents that basic infrastructure chassis 6A-A section shape is the section of 7 regular hexagons compositions.
Fig. 3 is that the second of Figure 1A-A sectional view executes example, represents that basic infrastructure chassis 6A-A section shape is circular section.
Fig. 4 is that the first of Figure 1B-B sectional view executes example, represents that basic top column 4B-B section shape is the section of regular hexagon.
Fig. 5 is that the second of Figure 1B-B sectional view executes example, represents that basic top column 4B-B section shape is circular section.
The work progress of wind driven generator base of the present invention is:
1. stake holes 10 is fixed in precasting yard integral prefabricated basic top column 4 by land, basic infrastructure chassis 6, a plurality of support.
Prefabricated employing is continuous line production system in enormous quantities, uses professional production equipment and instrument, land making convenient and quick construction safety, reduces the workload of offshore construction as far as possible, and the marine ships of minimizing costliness is constructed, and raises the efficiency and reduces costs.
2. the lower water in basis and floating transport.
When using Reinforced Concrete Materials to make wind driven generator base, basis due to volume weight comparatively large, lower water and marine transportation difficulty, large area chassis is applicable to floating transport, is transported to installation site venting sinks with tugboat is floating.The mud that the present invention is extremely not low to weak soil basis supporting force is replaced or consolidation process, and basic infrastructure chassis is placed directly on mud face, seabed, and greatly reduce the expense of construction and reduce costs, basic infrastructure chassis is fixing to support by supporting spud pile 11.
3. basic infrastructure chassis negative pressure is sunk and leveling.
Continue the air extracting chassis enclosure space out, form negative pressure, basic infrastructure chassis 6 is pressed in the mud on weak soil basis by negative pressure.Make the negative pressure of basic infrastructure chassis 6 diverse location different, in order to control the deflection of basic infrastructure chassis 6 all directions, accurately carry out the leveling on basic infrastructure chassis 6, guarantee the installation quality of offshore wind generating.
4. squeeze in the fixing stake holes 10 of support and support spud pile 11, perfusion is closed the support spud pile supporting spud pile 11 and to be bound the concrete of block 9.
