Abstract
The invention discloses a megawatt generation device, particularly an ocean current generation device, which comprises a generator. The ocean current generation device is characterized in that: the generator is driven b a belt pulley to generate power; a belt is arranged on the belt pulley; energy acquisition devices are arranged on the belt, and are vertically arranged blades which are arranged on the belt by an inverted T-shaped bracket; and the blades are connected with the bracket by hinges. The ocean current generation device provided by the invention has the advantages that: the generator is driven by the kinetic energy of ocean current to generate the power; and the ocean current generation device is applied to shallow sea, has a high energy conversion rate and can realize the power generation of 3 to 5 megawatts per hour when arranged in ocean with the flow rate of 2 to 3 meters per second.
Description
Technical field
The invention 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, 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 present invention is in order to remedy the deficiencies in the prior art, and a kind of simple in structure, power generation device from sea current of being applicable to the shallow sea is provided.
The present invention is achieved through the following technical solutions:
A kind of power generation device from sea current, comprise generator, its special way is: described generator drives generating by belt pulley, affiliated belt pulley is provided with belt, described belt is provided with electricity energy harvester, electricity energy harvester is the blade that vertically is provided with, and described blade pass is crossed the font of falling T support and is installed on the belt, links together by folding between described blade and the support.
Power generation device from sea current of the present invention, be that blade drives the skin rotation above the belt under the promotion of ocean current by being arranged on, top blade is done positive work in movement process, it is useful work, get blade below and do negative work, it is idle work, when blade contacts with the ocean current forward during on belt top, this moment, area of contact was bigger, vacuum side of blade leans against on the support, when blade forwards the below of belt to, blade is under the impact of current, the axle of blade in folding rotates 90 degree, this moment, blade and support were straight line, the side of blade contacts with ocean current, area of contact is smaller, and 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, vacuum side of blade below this moment contacts with current direction, and area of contact is bigger, and the blade above the belt contacts with current at the impact downside of ocean current, 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, described belt is a Timing Belt, and belt pulley is a toothed wheel.
The beneficial effect of power generation device from sea current of the present invention: realized the kinetic energy of ocean current is driven generator for electricity generation, be applicable to the shallow sea, and the energy transformation ratio height, 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
The present invention is further illustrated below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention;
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 present invention.This embodiment comprises generator, it is characterized in that: described generator drives generating by belt pulley 2, affiliated belt pulley 2 is provided with belt 5, described belt 5 is provided with electricity energy harvester, and electricity energy harvester is the blade 3 that vertically is provided with, and described blade pass is crossed the font of falling T support 1 and is installed on the belt 5, link together by folding 4 between described blade 3 and the support 1, described blade 3 is a hollow structure, and described belt 5 is formal belt, and described belt pulley 2 is a toothed wheel.
This device is installed in blade 3 in the sea with the axle at belt pulley place over against the position of ocean current when mounted, and when ocean current arrives, blade 3 drives belt 5 and walks about under the impact of ocean current, thus the drive generator for electricity generation.The ocean current motion is more regular, general secondary positive movement is arranged every day, continue six hours, the secondary reversing motion at every turn, each lasting six hours, and continuity is stronger, 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 only is 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, can fast blade 3 be turned up during so that flog 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.
