Background technology
Wind-powered electricity generation is a kind of reproducible clean energy resource, and land Wind Power Development was rapid in recent years, but the wind energy that land can develop is very limited compared with the available wind energy content in coastal waters.Therefore, China's offshore wind farm has more potentiality to be exploited.An important process of offshore wind farms early development is acquisition and the assessment of wind-resources, and its most frequently used means set up anemometer tower exactly.
Anemometer tower is a kind of tall and slender structure building, tradition anemometer tower foundation form mostly is pile foundation or gravity type foundation, in view of the offshore construction of traditional anemometer tower foundation and mounting cost higher and recycle more loaded down with trivial details, the present invention is a kind of novel triangle buoyancy tank basis that can be applicable to offshore wind measuring tower structure, top is lattice tower, pylon buoyancy tank basis is connected by stiffener, buoyancy tank basis provides buoyancy for during anemometer tower towage, thus avoid the use of bulk transport boats and ships, only skiff need be adopted to arrive at the destination, thus greatly shorten the construction time, reduce costs.
Summary of the invention
The object of the invention is for above-mentioned technical Analysis, a kind of overall triangle buoyancy tank basis of the band lateral support for offshore anemometer tower is provided, this buoyancy tank basis can overall towage transportation by driving, the use of large-scale facility can be reduced in construction, reduce cost of transportation and difficulty of construction, effective shortening short construction period, reduces anemometer tower construction cost.
Technical scheme of the present invention:
A kind of overall triangle buoyancy tank basis of the band lateral support for offshore anemometer tower, end to end and be welded into the overall structure that basic plane is equilateral triangle by three buoyancy tanks, cuboid buoyancy tank is provided with Water filling valve, deep floor is provided with to strengthen the rigidity of buoyancy tank in buoyancy tank, square hole is provided with bottom deep floor, the lateral surface of three buoyancy tanks is respectively equipped with lateral support structure, lateral support structure is made up of three support arms and circular support platform and fixes with buoyancy tank side horizontal, the brace table of three lateral support structure is identical with the distance of three buoyancy tank sides and three brace tables are equilateral triangle, be plane three buoyancy tank intersections be the little buoyancy tank of pentagonal cavity, be provided with identical with little buoyancy tank cross sectional shape bottom little buoyancy tank, the anti-skid skirtboard case of bottom opening, buoyancy tank basis transportation by driving inserts sea bed to stop the slippage of buoyancy tank foundation level after predetermined construction location sinks, overall triangle buoyancy tank basis and top anemometer tower structure integral solder.
Described cuboid buoyancy tank is made up of Plate Welding, buoyancy tank length of side 12.5m, wide 2.5m, high 2.2m, steel plate wall thickness 25mm; Buoyancy tank inside is evenly equipped with the thick transversely stiffened plate of 18mm along its length, and be provided with the square hole of width 20cm, height 10cm bottom deep floor, deep floor spacing is 1.5m.
The little buoyancy tank height of described pentagon is 2.2m; The height of anti-skid skirtboard case is 0.6m, and the steel plate being 25mm by five pieces of wall thickness surrounds, and is highly 0.6m.
After this buoyancy tank basis adopts small-sized barge transportation by driving towage to predetermined construction location, by the Water filling valve on casing to water filling in buoyancy tank, sink down into design elevation and leveling, realize single step and install.
The invention has the beneficial effects as follows:
This buoyancy tank foundation structure good stability, stress performance good and be convenient to marine transportation by driving install; Truss-like anemometer tower structure can be installed in top, and pylon and buoyancy tank base solder integrally, provide buoyancy when buoyancy tank can be the towage of anemometer tower overall structure, avoids using bulk transport boats and ships, can reduce engineering cost, shortens the construction time of anemometer tower structure.
