Abstract

A swivel-shaped vertical shaft direct-driven tidal stream energy generator belongs to the technical field of renewable ocean energy resource utilization, and is characterized in that an induction coil is arranged in a circular ring surface of a stator; each rotor has a C-shaped cross section; three sides of the rotor cover the stator and is supported by the stator; magnets are mounted in an upper wall and a lower wall of the stator in pairs and are uniformly distributed along the circumference; the anisotropic magnetic poles are opposite; the magnetic poles of two pairs of adjacent magnets are oppositely arranged in the circumferential direction; a plurality of blades and the two circular ring rotors form a cage structure; the rotors rotate around a vertical shaft under the action of hydrodynamic force; and the magnetic fields of the rotors moves relative to the induction coil, and generates current in the induction coil to be output. The utility model has the benefits that a gear accelerator, a large bearing or a hydraulic system and other parts are not required, and only the whole cage structure consisting of the rotors and the blades in the whole device is a main moving element; therefore, the structure is simple and reliable, and the manufacturing, mounting and maintaining costs are greatly lowered.

Description

Turned-in annular vertical pivot directly driving type tidal current energy generating equipment

Technical field

The utility model belongs to regenerable marine energy and utilizes technical field, relates to a kind of turned-in annular vertical pivot directly driving type tidal current energy generating equipment.

Background technique

Using maximum tidal current energy generating equipments at present is horizontal axis turbines formula and vertical pivot turbo type device (as Darrieus type and Gorlov type turbine plant), has also occurred the device of non-turbo machine forms such as vibration hydrofoil formula in the recent period.The rotor of horizontal axis turbines formula and vertical pivot turbo type device is done rotatablely moving of many weeks around running shaft, and its rotating speed needs to drive generator again behind the gear accelerating unit raising rotating speed far below generator speed usually.And vibration hydrofoil formula device drives hydraulic pressure installation usually owing to only do the interior reciprocal rotation of small angle range, and the mechanical energy of rotating shaft is converted to the hydraulic pressure energy, passes through hydraulic motor-driving generator again.

No matter being gear accelerator or hydraulic pressure installation, all is complex structure, manufacturing, the demanding parts of assembly precision.Thereby cause manufacture cost height, poor reliability, marine difficult in maintenance, the total life cycle operation and the maintenance of installing brought negative effect.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, tidal current energy generating equipment that operational reliability is high, and solving existing trend can the apparatus structure complexity, manufacture cost height, reliability problem low, difficult in maintenance.

Principle of the present utility model is: direct drive generator and vertical pivot prismatic blade Darrieus turbo machine are combined into integral body, form a kind of novel tidal current energy generating equipment.Rotor is installed on the ring framework as the trend turbine bucket, and the ring framework is simultaneously also as the rotor of direct drive generator, in establish inductor coil; The ring member of supporting rotor is simultaneously also as the stator of direct drive generator, in establish magnet, rotor and stator constitute the core component of direct drive generator; The rotating speed of rotor rotation is not high, but turning radius is bigger, and is very big in the linear velocity at rotor outer rim place; According to the electricity generating principle of generator, when conductor motion cutting magnetic line, in conductor, can produce electric current, the linear velocity of conductor motion cutting magnetic line is big more, and the electric current of generation is big more.

The technological scheme that the utility model adopted is:

A kind of turned-in annular vertical pivot directly driving type tidal current energy generating equipment, this device comprises ring rotor, prismatic blade, ring stator, bearing, inductor coil, magnet.

The bottom is laid or be anchored in to base support.The ring stator is fixed on the base support.Many group sector conductor coils are embedded in the ring stator toroidal surface, evenly arrange along circumference; Two of each coils are drawn lead, and each coil homonymy is drawn lead and connected respectively, draws as the output line of direct drive generator.The cross section of ring rotor is a C shape, is enclosed within on the ring stator; On ring stator annulus card, annular slide track is set, a plurality of small-sized rollers are installed in the position of corresponding slideway on the ring rotor, make it to roll, guaranteeing relative position and the gap between ring stator and the ring rotor, and reduce the resistance of two member relative movement along slideway.Paired mounting magnet in the two side of ring rotor coating stator, opposite pole is relative, produces the magnetic field perpendicular to ring stator card; Many group magnet are evenly arranged along rotor circumference, make adjacent two pairs of magnet magnetic pole opposed, and promptly the pair of magnet N utmost point is last, and the S utmost point is following, and the then adjacent pair of magnet S utmost point is last, and the N utmost point is following, by that analogy; Adjacent two pairs of magnetic blow out centre equal on the stator sector (-shaped) coil along the spacing of two spur traverses of radial direction along the spacing of rotor circumference.A plurality of prismatic blades two ends are fixedly mounted on up and down on two ring-shaped rotors; A plurality of blades and two annulus rotors form a cage construction; Rotate around vertical pivot at the hydrodynamism lower rotor part, rotor field and stator coil relative movement produce electric current in stator coil, and export by output conductor.Rotor can be made of lightweight material, reduces weight.

Effect of the present utility model and benefit are: do not need parts such as gear accelerator, large size bearing or hydraulic system, the whole cage construction that whole device has only rotor and blade to form is a main motion parts, simple and reliable for structure, greatly reduce manufacturing, installation and maintenance cost.
