Existing Anti-Typhoon measure, one of conventional method is stiffening element bearing capacity, and such as basic pylon reinforcement, blade reinforcement, principal shaft braking moment and yaw braking square are strengthened; Another kind of method adopts initiatively protective measure, such as principal shaft braking brake, and prevailing wind direction is followed the trail of in impeller driftage, or impeller is quit work.Parts carrying strengthening measure all requires the rigidity and the main shaft moment that strengthen blade structure, this all requires that the mechanical property of blower fan promotes further, by the increase of mass loading when causing structural design, also can cause further manufacturing, the raising of the relevant cost such as transport and installation.Driving shaft mechanical braking can reduce the infringement of typhoon by brake, but braking state can make driving gear bear the torque load of constantly change, may cause the hidden danger such as driving cog fatigue fracture.And during typhoon; fan blade feathering runs can have certain protective role to blade; but it is limited to produce effects in practice; another kind of thinking is disassembled by huge blade between typhoon or thrown away by blade activation body; these class methods waste time and energy; need a large amount of special devices, time, cost do not allow.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming the Anti-Typhoon technology of existing wind-power generating system, a kind of brand-new simple possible is proposed, effectively can improve blade stress distribution, improve the Anti-Typhoon force control system of offshore wind farm of fan blade counter-bending anti-vibration ability.
To achieve these goals, the present invention adopts following technological scheme: a kind of marine Anti-Typhoon control yarn system is primarily of matrix part sleeve and control force supply part hawser composition.It is characterized in that: on all fan blades, install Anti-Typhoon control gear, control gear is assemblied on blade by tube-in-tube structure form, and mounting point distance blade tip 1/3rd leaf is long; Sleeve comprises upper and lower two intermediate plates, is connected, lower clamping piece on sleeve to ensure that sleeve is fixed on blade by the bolt assembly on intermediate plate edge; Be connected in the middle part of control force hawser and sleeve intermediate plate; Each blade is closely connected by control gear, to ensure the supply of additional control on each blade; Control force hawser with the corresponding rotation of blade in vane propeller-changing and feathering process, can not affect wind power system and normally works.
Useful benefit of the present invention is: provide counter-bending control force by control gear fan blade, reduce bending blade distortion and vibratory response, also stress intensity and the distortion of the positions such as root of blade mounting flange, clamping bolt will be reduced simultaneously, improve the vibrating fatigue phenomenon of fan blade, achieve the anti-typhoon capacity of offshore wind farm system.The present invention does not affect wind power system variable pitch and feathering work, system, produces and does not substantially produce new environmental problem with installing and using, and implementation cost is low, installing/dismounting speed fast, the equipment that needs is few.

Embodiment
Below in conjunction with accompanying drawing and concrete case study on implementation, the structure elements of composing and control of the Anti-Typhoon control system of offshore wind farm of the present invention is described in detail.
As shown in Figure 1, the wind-driven generator structure being provided with Anti-Typhoon control system comprises wheel hub 1, blade 2 and Anti-Typhoon control gear, and Anti-Typhoon control gear forms primarily of matrix part sleeve 3 and control force supply part hawser 4.All fan blades 2 are all provided with sleeve 3, and the mounting point of sleeve 3 on blade 2 is apart from blade tip 1/2nd leaf strong point.The sleeve 3 of each adjacent blades 2 is connected by control force hawser 4, three fan blades 2 are all coupled together by control force hawser 4 by the present invention, substantially increase the performances such as the counter-bending anti-vibration of fan blade like this, also ensure that the stability of the Anti-Typhoon system works of offshore wind farm.
As shown in Figure 2, sleeve 2 is made up of upper and lower two intermediate plates, is connected by upper lower clamping piece by the bolt assembly 3 on intermediate plate edge, and sleeve 2 is fixedly mounted on blade 1.Compact siro spinning technology in the middle part of control force hawser 4 and sleeve 2 intermediate plate, and hawser 4 two ends are connected respectively on the sleeve 2 of adjacent blades 1, it is connected that all blades 1 of such blower fan all pass through control force hawser 4.When larger blast load acts on fan blade 1 surperficial, control force hawser 4 provide additional counter-bending control force can to blade 1.
As shown in Figure 3, when conventional fan unit is subject to typhoon wind load, because strong wind destroys and turbulent flow, blade may produce structural damage or vibrating fatigue to the Anti-Typhoon control system workflow of offshore wind farm, finally causes blade damage or fracture.And when typhoon, offshore wind farm Anti-Typhoon control system energy fan blade provides counter-bending control force, improve the performances such as the flexural rigidity of blower fan, and then the bending large deformation situation improved at extreme wind load lower blade, and the stress intensity of fan blade and arbor join domain can be reduced, reduce the possibility of leaf destruction.Meanwhile, due to the existence of counter-bending control force and the raising of fan blade structure rigidity, the structural vibration response of fan blade also will decline to some extent, therefore control system vibrating fatigue phenomenon that also will improve turbulent flow and cause.Wind load be in blower fan can normal range of operation time, control force hawser can become with the corresponding rotation of blade in oar, feathering process at fan blade, ensures blower fan normal wind-powered electricity generation conversion work.The present invention does not affect the change oar feathering work of wind power system, from the Anti-Typhoon control gear of typhoon failure mechanism design, improves the Anti-Typhoon performance of blower fan under typhoon load, achieves the Anti-Typhoon control of offshore wind farm.
