Description
Technical field
The present invention relates to a kind of wind generator systems peculiar to vessel.
Background technique
Be typically provided on ship too can electricity generation system, but influenced by the sun it is very big, such as cloudy day or rain
When, solar energy can not provide electric power.
Wind-power electricity generation is a kind of clean renewable energy, and reserves are very huge, will be accounted in future world energy pattern
There is important position.Current large size horizontal-shaft wind turbine is commercially widely accepted, and also develops perfect, working principle increasingly
Be: airflow function drives generator to generate electric current on wind wheel, generating aerodynamic load driving wind wheel rotation.
But horizontal-shaft wind turbine construction is complex, rotating wind wheel size is big, and generating set places pylon top, causes
The tilting moment of unit is big, and with unit enlargement develop, the requirement to hull is also higher and higher, cause cost of electricity-generating compared with
Height, performance boost seriously constrain wind-powered electricity generation sustainable development on ship also close to the limit.
Summary of the invention
The present invention is directed to the solid deficiency of current wind-driven generator, proposes a kind of wind generator system peculiar to vessel, feature
It is: is constituted including vibrator 1 and damping fin group 2；Vibrator is the rigid hollow shell of truncated cone-shaped, and inner wall is fixed with damping
Piece group；Damping fin group is the matrix being made of 16 blocky damping fins, is divided into four column in the horizontal direction, by 90 ° of azimuths
Interval is evenly arranged on vibrator inner wall, is arranged as equidistant four layers in vertical direction.
It further include elastic support structure body 3 and piezoelectric material module 4, elastic support structure body 3 is the cylinder of composite material
Body structure；Piezoelectric material module 4 fastens and surrounds the outside wall surface of elastic support structure body, is highly entire elastic support structure
The 60% ~ 90% of body is located at the centre of elastic support structure body 3 in vertical direction.
It further include synthetic fiber rope 7 and spring damping stabilizer 8,7 upper end of synthetic fiber rope is fixed on vibrator 1
On, lower end is connect with spring damping stabilizer 8, and possesses certain length surplus.
Spring damping stabilizer 8 is made of single or multiple high-strength springs, is greater than maximum deviation in vibrator amplitude
When angle, damping increased dramatically, guarantee safety of the system under extreme tilting moment.
The maximum deviation angle is 30 °, is defined as the angle of vibrator middle line and vertical direction.
Compared with current wind-driven generator and other new configuration wind generator systems, wind-power electricity generation peculiar to vessel of the invention
System keeps away that utilization efficiency is high, it is simple to implement, is suitable for using on ship.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of wind generator system peculiar to vessel.
Fig. 2 is the schematic top plan view of AA section in Fig. 1.
Specific embodiment
As shown in Figure 1, wind generator system peculiar to vessel of the invention is to include vibrator 1, damping fin group 2, resilient support knot
Structure body 3, piezoelectric material module 4, synthetic fiber rope 7 and spring damping stabilizer 8.
The working method of present system is: the airflow function of external environment on truncated cone-shaped, rigid hollow vibrator,
By aerodynamic principle, air-flow will generate separation on wall surface, and be formed in wake flow and generate the vortex street that periodically falls off, vibration
Device can also generate periodic vibration；Damping fin group is fixed on the inner wall of vibrator, is made of 16 blocky damping fins
Matrix is divided into four column in the horizontal direction, is evenly arranged on vibrator inner wall by 90 ° of azimuthal separations, in vertical direction
On be arranged as equidistant four layers, effect is control vibrator and the best match of dynamic excitation frequency, is realized to amplitude and frequency
Control；Meanwhile the vibration of system superstructure has also driven elastic structure and piezoelectric material module to occur significantly to deform
Movement, elastic support structure body are the cylindrical structure of composite material, provide support for upper part-structure；Piezoelectric material module is same
Sample is compliant member, fastens and surround the outside wall surface of elastic support structure body, highly 60% for entire elastic support structure body
~ 90%, the centre of elastic support structure body is located in vertical direction, electric current is generated by the piezoelectric effect of piezoelectric material, then via change
Stream device unsteady flow passes to power grid or energy storage device after passing.In addition, the safety and stability ensuring equipment of system are by synthetic fibers
Rope and spring damping stabilizer are constituted, and synthetic fiber rope upper end is fixed on a shaker, lower end and spring damping stabilizer
Connection, and there are certain length surpluses, are small damping fortune to guarantee vibrator amplitude in the maximum deviation angular region of permission
It is dynamic；Maximum deviation angle is 30 °, is defined as the angle of vibrator middle line and vertical direction；Spring damping stabilizer be by single or
Multiple high-strength spring compositions increased dramatically damping, guarantee system is extremely being inclined when vibrator amplitude is greater than maximum deviation angle
Cover the safety under torque.
