Description
Technical field
The utility model belongs to field of ocean engineering, is related to a kind of marine large-scale single pile formula assembling efficiency of raising
Mechanical device
Background technology
Offshore wind turbine in the world can be divided into fixed and floatation type according to its support construction pattern.It has built up at present
Marine wind electric field concentrate on the shallow sea that the depth of water is less than 30 meters to fix based on single pile formula support construction.Single pile formula wind turbine pattern
Simply, easy for installation, there is greater advantage in economy.Since the limitation of shallow sea area has some state plans and exists in Europe
Single pile formula wind power plant is established in the marine site addressing of 40 meters of the depth of water or more.
The mounting means of single pile formula wind turbine includes branch's lifting and unit assembling of ship machinery, for large fan, the installation mould of mainstream
Formula is to install the more Fans of Ship Transportation using jack up.In order to efficiently use floor space, individual blade, pylon, cabin difference
It is stored as separate unit.During the installation process, jack-up unit spud leg is inserted into seabed, and platform, which is promoted, is higher than sea level, very greatly
The influence that wave force is avoided in degree operates to loop wheel machine and provides a firm platform.Successively to basis, blower fan tower barrel, wind
Machine cabin and four part of blade carry out lifting and close up.
In the hoisting process of cabin, generally use loop wheel machine constrains cabin by hawser vertically and horizontally
Movement, until the circular hole of cabin bottom and tower is perfectly aligned closes up.In hoisting process, due to the influence of turbulent wind, act on
Wind load in cabin constantly changes, and water shaking can occur for cabin.Meanwhile single pile can also be vibrated because of the influence of wave force,
Further cause the shake of atop a tower.During closing up, since position is difficult to be aligned, it is often necessary to multiple crew's hands
It is dynamic to assist operation, it is longer to expend the time.With the appearance (diameter is up to 8 meters) of ultra-large type single pile wind turbine, operating water depth into one
Step increases (more than 40 meters), and the movement of wave force and tower during closing up suffered by single pile increases, and can be further exacerbated by sea of meetings
Upper wind-powered electricity generation installation cost.
Utility model content
The utility model aim be to propose it is a kind of closing up the auxiliary device used for cabin installation, make tower drum flange and machine
Cabin bottom circular aperture is closed up docking operation and can be quickly completed.
The technical solution of the utility model：
A kind of active damping unit being suitable for marine single pile formula assembling, includes the quality in tower 7
Block 8, spring 9, damper 10, force effect device 11, controller, electro-motor and battery, and the sensor in cabin 5
(Differential Global Positioning System DGPS)；
Mass block 8 is connect by spring 9 with 7 inner wall of tower, and damper 10 and 11 both ends of force effect device respectively connect matter
7 inner wall of gauge block 8 and tower；Mass block 8, spring 9, damper 10 selection should be according to vibration principle, for 7 structure of tower
First natural frequency optimizes adjustment；When installation is complete for tower 7, spring 9 and damper 10 are started to work, and quality is passed through
The movement of block 8, the movement of partial offset tower 7 caused by wave force；Before closing up, force effect device 11 is started to work；Root
The exact position of cabin 5 is obtained according to Differential Global Positioning System DGPS, by force effect device 11, adjustment tower 7 is in the horizontal plane
Position.
The mass block 8 can be solid or liquid unit.
The material of the damper 10 can be rubber.
The force effect device 11 by tower 7 controller and small electric motors drive.
Crucial moment before cabin 5 is closed up, tower 7 are influenced that plane motion by a relatively large margin may occur by wave force.
By mass block 8- spring 9- dampers 10, reduce the plane motion of tower 7.By the active control of force effect device 11, according to
The position of aerial cabin 5 adjusts the position of tower 7 to help to close up.
When cabin 5 and tower 7 are successfully docked, cabin 5 is bolted in tower 7, closes active force effect device
11；And still played a key effect in fan operation by the damping system that mass block 8- spring 9- dampers 10 are constituted, it carries
The fatigue life of high single pile structure.
The wind turbine type that the utility model is applicable in is MW grades of horizontal axis wind-driven generators, and the depth of water is more than 30 meters of scene.
The beneficial effects of the utility model：
(1) installation of the active damping unit, debugging can by land cabin components install when complete.Its composition portion
Part, force effect device, mass block, spring, damping and controller, electro-motor, battery are the industrial products of maturation, are easy real
It applies.
(2) installation time offshore for shortening cabin, reduces set-up time and cost.
(3) when cabin is docked, the degree of automation is improved, human cost is reduced, improves processing safety.
