Abstract
The utility model discloses a megawatt-grade power generation device, especially an ocean current power generation device, which comprises a generator and is characterized in that the generator is driven by a belt pulley to generate power. The belt pulley is provided with a belt and the belt is provided with an energy collecting unit. The energy collecting unit comprises a vertically arranged blade and the blade is arranged on the belt through an inverted T-shaped support. The blade and the support are connected together through a hinge. When the ocean current power generation device is in use, the generator is driven by the kinetic energy of the ocean current to generate power. The ocean current power generation device can be applied to shallow seas and is high in energy conversion rate. When the ocean current power generation device is arranged in a sea with the flow velocity thereof to be two to three meters per second, three to five megawatts of electricity can be generated per hour.
Description
Technical field
The utility model discloses a kind of MW class electricity generating device, is a kind of power generation device from sea current specifically.
Background technique
Huge energy is being contained in the ocean, and the equipment that present energy with water is the power generation electric energy is a lot, but major part is to utilize the potential energy of water; Seawater clocklike flows and forms ocean current; Existing power generation device from sea current structure more complicated, and Applicable scope is less, is only applicable in the middle of the deep-sea; Be not suitable in the shallow sea, obviously designing a equipment of the current power generation in shallow sea that is applicable to becomes the matter of utmost importance that solves energy problem.
Summary of the invention
The utility model is in order to remedy the deficiency of existing technology, and a kind of simple in structure, power generation device from sea current of being applicable to the shallow sea is provided.
The utility model is realized through following technological scheme:
A kind of power generation device from sea current; Comprise generator, its special way is: said generator drives generating through belt pulley, and affiliated belt pulley is provided with belt; Said belt is provided with electricity energy harvester; Electricity energy harvester is the blade that vertically is provided with, and said blade pass is crossed the font of falling T support and is installed on the belt, links together through folding between said blade and the support.
The power generation device from sea current of the utility model is that blade drives the skin rotation above the belt under the promotion of ocean current through being arranged on, and top blade is done positive work, i.e. useful work in movement process; Below blade done negative work, i.e. idle work, when blade contacts with the ocean current forward during on belt top, area of contact is bigger at this moment; Vacuum side of blade leans against on the support, and when blade forwarded the below of belt to, blade was under the impact of current, and the axle of blade in folding rotates 90 degree; This moment, blade and support were straight line, and the side of blade contacts with ocean current, and area of contact is smaller; The coefficient that blocks water is very little, much smaller than the coefficient that blocks water of top blade, thereby can drive generator for electricity generation; When current direction when flowing in the other direction, under the effect of ocean current, the axle of blade in folding below the belt rotates; Face of blade leans against on the support, and this moment, following vacuum side of blade contacted with current direction, and area of contact is bigger; Blade above the belt contacts with current at the impact downside of ocean current, and area of contact is less, and the blade below in reverse procedure is in and drives generator and do positive work.
In order to reduce idle work, improve generating efficiency, blade is made hollow; Synchronous in order to guarantee in the belt rotation process, said belt is a Timing Belt, and belt pulley is a toothed wheel.
The beneficial effect of the utility model power generation device from sea current: realized the kinetic energy of ocean current is driven generator for electricity generation; Be applicable to the shallow sea; And energy transformation ratio is high, this device is put in two to three metre per second (m/s)s flow velocity in the sea, and per hour can realize generating electricity three to five megawatts.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model;
Among the figure, 1, support, 2, belt pulley, 3, blade, 4, folding, 5, belt.
Embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises generator, it is characterized in that: said generator drives generating through belt pulley 2, and affiliated belt pulley 2 is provided with belt 5; Said belt 5 is provided with electricity energy harvester, and electricity energy harvester is the blade 3 that vertically is provided with, and said blade pass is crossed the font of falling T support 1 and is installed on the belt 5; Link together through folding 4 between said blade 3 and the support 1; Said blade 3 is a hollow structure, and said belt 5 is formal belt, and said belt pulley 2 is a toothed wheel.
This device is installed in the position of blade 3 over against ocean current in the sea with the axle that belt pulley belongs to when mounted, and when the ocean current arriving, blade 3 drives belt 5 and walks about under the impact of ocean current, thereby drives generator for electricity generation.The ocean current motion is more regular, and general secondary positive movement is arranged every day, continues six hours at every turn; The secondary reversing motion continue six hours, and continuity is stronger at every turn; Thereby generating is more steady, and generated energy is also bigger, this install flow velocity that unit group only is put into two to three metre per second (m/s)s in the sea; Per hour just can realize generating three to five megawatts, a year generating dutation can reach more than 6,000 hours, and annual electricity generating capacity is up to more than 2,000 ten thousand degree.This embodiment is merely a kind of embodiment of this equipment, and is unrestricted to the present invention, every this principle of utilization all belong to protection scope of the present invention.
In order to be that blade 3 can be turned up or open timely; Reduce idle work; Improve generating efficiency, the side of blade 3 can the beveling structure, so that can fast blade 3 be turned up when flogging a dead horse; Also can make blade 3 and current direction that a little angle is arranged when mounted, so that under the impact of ocean current, open timely and turn up.
