Background technique
Development along with global economy, the non-renewable energy resources fossil fuel of the earth peter out and greenhouse effect day by day serious, increasing country starts to pay close attention to the exploitation of new cleaning fuel, Ocean Tidal Current Energy becomes the focus receiving much concern undoubtedly, Ocean Tidal Current Energy generating is exactly directly to utilize the mechanical devices such as water impact impeller of fluctuation tidewater to generate electricity, because having regular every day, sea tide changes its size and Orientation twice, marine tidal-current energy generating does not need to construct a dam to store water and can not produce the three wastes to environment, do not exist in conventional hydropower station construction and take farmland, the problems such as immigrant, and marine tidal-current energy storage volume is greatly inexhaustible, but the energy density of marine tidal-current energy is lower, be dispersed in current, the water velocity of trend directly affects the generating efficiency of generator, at present a lot of electricity generating devices are only to utilize blade under water hammer, to drive the rotating shaft direct generation of electricity, not only generating efficiency is low and blade when rotating often because there is stuck phenomenon in both direction stress balance, and whole marine tidal-current energy generator device in installation process often because ground injustice cause device also injustice cannot regulate.In order to solve the problem of current tidal current energy generating equipment, need to develop a level of controlling device at any time, can make more concentrated by the flow energy of blade, direction is more unified, the novel tidal current energy generating equipment that generating efficiency is higher, cost of investment is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of tidal current energy generating equipment.
Problem to be solved in the utility model is current tidal current energy generating equipment pedestal adjusting level at any time, and, direction concentrated by the flow energy of blade disperses to make blade easily stuck, the problem that generating efficiency is low.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of tidal current energy generating equipment, comprise base, adjusting bolt, air guide sleeve, generator pedestal, rotating shaft, speed increaser, generator, stator and blade, air guide sleeve is the steel structure connecting in the middle of surrounding sealing, air guide sleeve is designed to the little flaring structure in large centre, two, bottom, air guide sleeve two ends is welded with base, base is by forming one by adjusting bolt between upper and lower two block plates, in the Vertical direction of air guide sleeve middle, rotating shaft is housed, rotating shaft is through air guide sleeve, rotating shaft upper end is equipped with speed increaser and generator successively, generator is arranged on generator pedestal, generator pedestal is welded on above air guide sleeve, two supporting legs of generator pedestal support on the ground, rotating shaft is equipped with blade on the part circumferencial direction of air guide sleeve the inside, air guide sleeve inlet and outlet is equipped with stator, stator is installed between air guide sleeve upper plate and lower plate, stator drives rotating shaft fast rotational after making water (flow) direction more unanimously impact blade, rotating shaft passes to generator by kinetic energy after by speed increaser, generator is electric energy by kinetic transformation.
Air guide sleeve, base and generator base-plates surface be brushing hull special anti-corrosion paint all; Blade is magnalium shaping material, and blade quantity is between 10-18 sheet; Stator is SUS316 stainless steel material, and stator respectively has 2 in air guide sleeve inlet and outlet.
The utility model has the advantages that: on base, set up the levelness that adjusting bolt facilitates controlling device, effectively avoid device in transportation or installation process to occur that height phenomenon causes blade when rotating, to produce distortion power and damages rotating shaft, the selecting of blade magnesium-aluminium alloy material not only met the energy consumption that the needs of intensity in rotary course more can reduce in blade rotary course self, the air guide sleeve design of flaring structure makes more current pass through blade, make flow energy more concentrated, simultaneously in air guide sleeve stator set up the direction that can change current, make water (flow) direction more unanimously reduce opposing torque, improving capacitation efficiency makes generating efficiency higher.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
A kind of tidal current energy generating equipment of the utility model, comprise base 1, adjusting bolt 2, air guide sleeve 3, generator pedestal 4, rotating shaft 5, speed increaser 6, generator 7, stator 8 and blade 9, the steel structure of air guide sleeve 3 for connecting in the middle of surrounding sealing, air guide sleeve 3 is designed to the little flaring structure in large centre, two makes more current rush at blade 9, make flow energy more concentrated, air guide sleeve 3 bottoms, two ends are welded with base 1, base 1 is by forming one by adjusting bolt 2 between upper and lower two block plates, adjusting bolt 2 facilitates the levelness of controlling device effectively to avoid device in transportation or installation process to occur that height phenomenon causes blade 9 when rotating, to produce distortion power and damages rotating shaft 5, in air guide sleeve 3 middle Vertical direction, rotating shaft 5 is housed, rotating shaft 5 is through air guide sleeve 3, rotating shaft 5 upper ends are equipped with speed increaser 6 and generator 7 successively, thereby speed increaser 6 can improve the rotating speed of generator 7 main shafts and improve generating efficiency, generator 7 is arranged on generator pedestal 4, generator pedestal 4 is welded on above air guide sleeve 3, two supporting legs of generator pedestal 4 support and make on the ground structure more stable, rotating shaft 5 is equipped with 10-18 sheet blade 9 on air guide sleeve 3 the inside part circumferencial directions, blade 9 can reduce oneself energy consumption in rotary course for the needs that magnesium-aluminium alloy material can not only meet intensity simultaneously, air guide sleeve 3 inlet and outlet are equipped with the stator 8 of two SUS316 stainless steel materials, stator 8 is installed between air guide sleeve 3 upper plates and lower plate, stator 8 can change the direction of current, make water (flow) direction more unanimously reduce opposing torque and impact blade 9 raising capacitation efficiency, blade 9 drives rotating shaft 5 fast rotational, rotating shaft 5 passes to generator 7 by kinetic energy after by speed increaser 6, generator 7 is electric energy by kinetic transformation, air guide sleeve 3, device working life is improved on base 1 and generator pedestal 4 surfaces all brushing hull special anti-corrosion paint.
The utility model using method, choose trend steady, after the large working sea area of tide flow, accomplish fluently ground, after the tidal current energy generating equipment of having produced is on land installed on ground according to direction of tide, utilize adjusting bolt 2 that device is mixed up to levelness, machinery and electrical engineer are by corresponding mechanical part, after cable and signaling line connect and debug, allow electricity generating device just can in generating state, when flood tide or at ebb tide current just can auto impact blade 9 make blade 9 rotations after by air guide sleeve 3, blade 9 drives rotating shaft 5 rotations, rotating shaft 5 passes to kinetic energy generator 7 after speed increaser 6, generator 7 is that electric energy utilizes for people by kinetic transformation, twice of electricity generating device every day no matter flood tide still ebb tide all can automatic generation, therefore the utlity model has controlling device level at any time, can make the advantages such as more concentrated by the flow energy of blade, direction is more unified, and generating efficiency is higher, cost of investment is lower.
