Description
Technical field
The utility model relates to a kind of electricity generating device, specifically tidal generating set.
Background technique
Ocean energy is as a kind of clean reproducible energy, and its exploitation can not produce waste water, waste gas, also can not take large stretch of good farmland, more not have radiation pollution.Countries in the world accelerate one after another to be studied the exploitation of ocean energy.Marine tidal-current energy is as the one of marine energy, and the research developed about it is rapid in development in recent years.Research experience about tidal current energy generating equipment is mainly derived from wind generating unit, but the averag density due to seawater is about 800 times of air, so two kinds of units are under the condition of equal-wattage grade, the overall dimensions of marine tidal-current energy power generation hydraulic unit is much less than the overall dimensions of wind power generating set, and this is also to strengthen the major reason to tidal current energy generating equipment research.
Tidal current energy generating equipment, according to water turbine running shaft and the position relationship coming flow path direction and sea level, can be divided into horizontal axial type and vertical shaft type substantially.Compared with horizontal axis water turbine type tidal current energy generating equipment, it is strong that vertical shaft water turbine formula tidal current energy generating equipment has adaptation flow direction property, and be applicable to the features such as large scale array layout, application advantage is obvious.The carrier format of vertical shaft water turbine formula tidal current energy generating equipment is varied.Publication number is disclose a kind of high-power vertical (standing) axle tidal generating set in the patent document of CN101705904A, design a kind of carrier format being connected gravity type base for post and king-post by universal spherical joint, its cabin is arranged on king-post top, and cabin outer rim is distributed with anchor chain orderliness and keg float and anchor chain is connected on anchor with hawser.This carrier format allows unit to swing with ocean current, and (using universal spherical joint connection and anchor chain to add fixedly makes whole carrier be in semi-active state, allow main shaft to a certain extent with stream swing), the unit operating time phase is caused to be in swing state like this, certain damage is caused to the assembling between unit internal structure, and be unfavorable for that unit seals, and installation process is complicated, is unsuitable for operation on the sea.
The general composition form of water turbine is carrier, impeller, speeder and generator set, and speeder often designs too complexity and causes water turbine axial dimension very large, makes the volume and weight of whole water turbine excessive, causes inconvenience to installation and maintenance.Therefore, how to reduce the axial dimension of tidal current energy generating equipment, weight reduction, reduce underwater sealing difficulty, become the technical barrier that those skilled in the art are urgently to be resolved hurrily.Publication number is that the patent of CN102889162A proposes a kind of permanent magnet semi-direct-drive type tidal power generation, half directly driving type combination of simple variable-speed device and permanent magnetism straight hair motor is adopted to adapt to the slow-speed of revolution of low water speed, such simplification speeder design in conjunction with direct driving motor makes the axial dimension of water turbine have certain reduction, but between speeder with generator case subdivision assembling and design equally complicated with traditional approach, namely fundamentally do not solve the technical problem of reduction unit axis volume.

Embodiment
Below in conjunction with accompanying drawing citing, the utility model is described in more detail:
Composition graphs 1 ~ 2, integrated half direct drive tidal power generating device of the utility model forms primarily of pile foundation 1, blade wheel structure and the integrated parts such as generator of partly directly driving, and is that one can adapt to the powerful tidal current energy generating equipment of low flow velocity.
As shown in Figure 1, pile foundation 1 is the carrier of whole tidal generating set, by the position that seabed fixes whole electricity generating device is squeezed in the lower end of pile foundation 1.Composition graphs 1 and Fig. 2, blade wheel structure is installed on the middle part of pile foundation, is placed in below horizontal plane, forms primarily of parts such as outer beam barrel 2, wheel hub 3, blade 4, bearing 5, spoke 6 and interior beam barrels 14.Wherein outer beam barrel 2, wheel hub 3, blade 4 are all fixedly connected with spoke 6, and interior beam barrel 14 is affixed with pile foundation 1, realizes relatively rotating between interior beam barrel 14 and outer beam barrel 2 by bearing 5.Blade 4 accepts washing away of current, water flow dynamic energy is converted into the rotation of blade wheel structure, and the quantity of blade 4 generally selects 3 or 4.The integrated generator that partly directly drives is by planetary gears with directly drive generator two-part and form, and planetary gears comprises ring gear 10, planet wheel 11, central gear 12 and planet carrier 15 and forms; Directly drive generator and mainly comprise the parts compositions such as external stator 7, internal rotor 8 and casing 9.The outer beam barrel 2 that rotates through of blade wheel structure is fixedly connected with to be delivered to planet carrier 15 and partly directly drives master section, and the rotation of planet carrier 15 drives the rotation of planet wheel 11 and central gear 12, achieves the speedup transmission of wheel rotation.Internal rotor 8 and central gear 12 rotatingshaft of generator are connected, and realize the conversion of kinetic energy to electric energy, external stator 7 and ring gear are all fixed on generator casing body 9.The axle of pile foundation 1 is through blade wheel structure and partly directly drive generator, and top is fixedly connected with end cap outer cover 13.
As shown in Figure 1 and Figure 2, in addition to the above, the control apparatus of some necessity can be arranged on pile foundation 1 inside, when keeping in repair tidal current energy generating equipment, maintenance man can open the end cap outer cover 13 that pile foundation 1 is pushed up, and then enters the care and maintenance that control apparatus is carried out in pile foundation 1 inside.The external stator 7 of pile foundation vertical shaft direct drive tidal power generating device and internal rotor 8 are all away from seawater levels, and the requirement for mechanical dynamic seal is lower, do not worry that seawater enters in the casing 9 of generator, affect the normal work of tidal current energy generating equipment.
Selection has comparatively low flow velocity marine site runner, pile foundation vertical shaft half direct drive tidal power generating device is arranged in water channel, when strength of current reaches toggle speed, impeller rotates under the impact of trend, planet carrier 15 is driven to rotate by the rotation of outer beam barrel 2, drive planet wheel 11 and ring gear 10 and central gear 12 engagement driving by planet carrier again, increase the rotating speed of central gear 12 thus internal rotor 8 rotating speed of raising generator.This device can also adapt to the flowing of marine tidal-current energy any direction simultaneously, without the need to the blade pitch device of the convection mechanism or blade that design water turbine set.
