Description
Technical field
The utility model belongs to the technical field of Oversea wind power generation and mariculture, more particularly to one kind based on single
The structure that the compound cylindrical foundation of offshore wind turbine is combined with spiral skeleton net cage.
Background technology
In recent years, offshore wind farm is quickly grown as a kind of green clean reproducible energy.Offshore wind farm has wind field matter
It measures, the significant advantages such as turbulivity is small, be not take up arable land, annual utilization hours height.But due to maritime environment complexity, stormy waves stream is to base
The coupling of plinth and pylon structure is complicated, and seawater is apparent with corrosion function to washing away for basis, so offshore wind farm is to basis
More demanding, offshore wind power foundation construction cost is higher.
The industrial crops quality of off-lying sea cage culture is good, and yield is good, high financial profit, has huge development potentiality.But
Be since off-lying sea stormy waves is larger, needed for net cage material, structure and anchoring system and coastal waters cage culture cannot be mentioned in the same breath,
And lack power supply facilities, belong to high investment, high risk industry.
Offshore wind turbine foundation is combined with marine cage structure to be helped to reduce capital construction cost, is increased economic efficiency and ecology
Benefit.
Offshore wind turbine foundation with the structure type that marine cage structure is combined must not be to wind turbine safe operation and net cage
Normal cultivation activity generate cross influence.
It needs to solve the problems, such as that offshore wind turbine foundation is stopped with the ship for the structure type that cage structure is combined.
Offshore wind turbine foundation is washed away by wave and flow, this causes the normal safe operation of offshore wind turbine foundation hidden
Suffer from, and the method that currently used jackstone goes along with sb. to guard him basis is ineffective, and it is more serious to wash away problem.
Invention content
The utility model is intended in view of the above-mentioned problems, proposing a kind of spiral aquaculture net cage knot based on compound bucket foundation
Structure is realized under the premise of not contacting blower fan tower barrel, net cage is combined with compound bucket foundation, to improve compound bucket foundation
Utilization ratio and net cage capacity of anti-storm, technology solves the problems, such as ship stop and personnel wind turbine up and down with open arms, and utilizes the knot
Structure mitigation bucket foundation washes away problem.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of spiral aquaculture net cage based on compound bucket foundation, including compound bucket foundation, on the basis of compound cartridge type
Equipped with net cage spiral skeleton, net cage spiral skeleton is helical structure identical with bucket foundation cap diameter；Including spiral skeleton
Support column, upper end weld together with net cage spiral skeleton bottom, and lower end is made as an entirety in advance with bucket foundation；Including net
Clothing, extension invest on the inside of net cage spiral skeleton；Including cushion pad, it is fixed on the outside of net cage spiral skeleton；Including ring ladder, installation
In the upper surface of net cage spiral skeleton；Ladder is connected including tower, net cage spiral skeleton is connected by two platforms and an inclined ladder
On ring ladder and blower fan tower barrel.It is elongate steel plate or high-strength aluminium alloy plate, upper and lower including spiral skeleton connecting rod
It is separately fixed on two helical layers of net cage spiral skeleton the top.Including changeover portion, it is connect with cylindrical foundation head cover top；It crosses
It is steel construction to cross section, and diameter is suitable with blower fan tower barrel lower end diameter, is connected with blower fan tower barrel by flange.
The net cage spiral skeleton is the helical structure that helix angle is 30-60 °, is hollow stainless steel tube or high intensity
Aluminium-alloy pipe material, top are equipped with polyethylene pipe.
It is bolted on the inside of the spiral skeleton connecting rod upper end and the polyethylene pipe of net cage spiral skeleton top layer, under
End is welded in net cage spiral skeleton middle layer inside spiral, for reinforcing the branch between net cage spiral skeleton top layer and its lower layer
It supports and connect.
It is to be hinged between the platform and inclined ladder of the tower connection ladder.The ring ladder both sides and tower connection
Terraced both sides are equipped with guardrail.
To be hinged between the horizontal bar and a heel post of the outer side rail of the ring ladder, and blocks and lean against another heel post
On, so that horizontal bar is rotated by 90 ° counterclockwise.
The spiral skeleton support column is heavy wall stainless steel cylinder or high-strength aluminum alloy cylinder.The cushion pad is trapezoidal
Section strip rubber product.
The spiral skeleton support column totally 4, is distributed in head cover；Spiral skeleton connecting rod totally 4, along net cage helical bone
Frame spiral circumference is uniformly distributed.
The advantages of the utility model and advantageous effect
Mariculture net cage is installed on offshore wind turbine combined type bucket foundation by it, utilizes wind-driven generator building equipment
As the infrastructure of marine cage culture, to which the building equipment of offshore wind generating and marine cage culture facility be built
If in conjunction with capital construction cost is advantageously reduced.
The structural style of net cage spiral skeleton makes the hook attachment of etting and skeleton be dispersed throughout etting circumference and etting axial direction,
More and uniformly distributed tie points keeps the connection of etting and skeleton more secured, and spiral skeleton also plays etting under the conditions of stormy waves
To protective effect, and the rigid connection of Net-cage frame and offshore wind turbine combined type bucket foundation contributes to the steady of net cage entirety
It is qualitative, thus based on the spiral aquaculture net cage of compound bucket foundation, volumetric loss rate is small under Lidar Equation, capacity of anti-storm
By force.
Spiral aquaculture net cage build is similar to spring, belongs to flexible structure in the horizontal direction, by cross force
Effect is lower to have certain cushioning effect, therefore advantageously reduces pair that net cage generates due to by stormy waves load or ship stop
The active force of blower fan tower barrel and combined type bucket foundation, to be conducive to the safe operation of wind turbine.
Since net cage spiral skeleton is that annular rises, ring ladder invests above net cage spiral skeleton, so ship can
It is stopped easily in arbitrary water level, and the mode of wind turbine above and below staff is changed to away ladder by cat ladder, substantially increased
The safety coefficient of upper and lower wind turbine.
The etting of net cage can make by wave generate wave breaking by there is certain wave absorption ability, in addition net cage knot
Structure disturbs peripheral flow phenomenon of the flow to changeover portion and tower, washes away problem to alleviate bucket foundation.
