The invention discloses a novel fluid kinetic energy conversion device with simple manufacture, low production cost, convenient maintenance, high flexibility and high efficiency, comprising a fluid bag, a rotating shaft and a fluid bag stand. The invention is mainly used for converting wind energy and water kinetic energy to mechanical energy so as to be applied to required equipment (such as a generator).
Description
Technical field
A kind of novel fluid kinetic energy conversion device particularly relates to the device (F03D, F03B) that wind energy, hydrodynamic(al) can convert mechanical energy to.
Background technique
At present the fluid dynamic energy switch technology has the rotating shaft turbine-type parallel with direction of flow, propeller type, the rotating shaft pocket formula vertical with direction of flow, loose-leaf type etc., but not the meeting of employing fluid pocket type.
Summary of the invention
The objective of the invention is for remedying the vacancy of prior art, provide a kind of can as small-sized to super sized type, making is simple and easy, cost of production is low, easy to maintenance, flexibility is strong, the novel fluid kinetic energy conversion device of dynamical fluid pocket type.
Novel fluid kinetic energy conversion device of the present invention comprises fluid bag, rotating shaft and fluid bag bracket.The fluid bag bracket is fixed on and is used for fixing fluid bag certain orientation in non-shaft centerline position in the rotating shaft, and as the power transmission; The fluid bag is no less than 2, distributes for the center population equilibrium with the shaft centerline; Fluid sack direction be with the shaft centerline be the center clockwise or unified counterclockwise towards.
Main points of the present invention are the fluid bag, and it is to be made by membranaceous or lamellar soft material (as cloth, plastic film, composite membrane etc.), and when tractive fluid sack made the fluid sack meet stream, fluid can enter the fluid bag, make the expansion of fluid bag, and it is maximum that choked flow power can reach; When making fluid sack back of the body stream at the bottom of the tractive fluid bag, the fluid in the fluid bag can be drained by pressurized, and the fluid bag is drawn in, and it is minimum that choked flow power can become.
The present invention utilizes above-mentioned this characteristic of fluid bag.When novel fluid kinetic energy conversion device of the present invention is in the fluid, rotating shaft vertical with direction of flow or crossing (can not be parallel), the side that the fluid bag is met stream at sack is understood absorption fluids kinetic energy and the rotation of pull fluid bag bracket, use for equipment needed thereby (as generator) by the rotating shaft output kinetic energy again, thereby reach the purpose that fluid dynamic energy converts mechanical energy to.
The present invention is all right: the fluid bag is whole or local to be connected with fluid bag bracket or rotating shaft by stay cord, make stay cord do the power transmission therein, and can function as follows: stay cord and soft fluid bag constitute the nature buffering, by stay cord control fluid sack aperture, in stay cord, be connected in series fluid bag buffering device and is used for the fluid bag and cushions, utilize resilient stay cord to cushion.
The present invention is all right: the fluid bag has support.Support can make the fluid bag open fast when opening, adopt the elasticity material to make can to utilize support to make fluid bag buffering, support as support connects that fluid bag buffering device is made fluid bag buffering, support connects speed-controlling device control fluid sack opening width.
The present invention can also have speed-controlling device directly or indirectly to act on the fluid bag, control fluid sack opening width and realize control speed.
The present invention can also have fluid bag buffering device directly or indirectly to act on the fluid bag, reduces the open impact of moment of fluid bag and reduces noise.
The invention has the beneficial effects as follows: a. adopts the fluid bag to make energy-absorbing, the fluid bag is to be made by membranaceous or lamellar soft material (as cloth, plastic film, composite membrane etc.), draw materials easily, making is simple and easy and oeverall quality is light, the requirement of strength of countershaft and fluid bag bracket is not high, makes cost of production low; B. adopt the fluid bag constructions to have the advantage easy, easy to maintenance, that flexibility is strong is installed; C. the commentaries on classics of fluid bag can be opened at a side pocket mouth of energy-absorbing, at utmost energy-absorbing; The side pocket mouth that the fluid bag changes in the power consumption of circling round can draw in, makes power consumption minimum when circling round, and therefore fluid kenetic energy converting device of the present invention has very high usefulness.

Embodiment
Fig. 1 is the embodiment of the fluid kenetic energy converting device of half pocket type structure among the present invention.The fluid bag is directly installed on the fluid bag bracket 2 for 3 half bags, and fluid bag bracket 2 balances are fixed in the rotating shaft 1, and the fluid sack is that the center is towards unanimity with rotating shaft 1.This device is placed fluid, and a side pocket mouth that changes in the power consumption of circling round when fluid bag 3 can draw in, and a side pocket mouth that changes at energy-absorbing when fluid bag 3 can open, and fluid bag 3 can the absorption fluids kinetic energy and 2 rotations of pull fluid bag bracket; Use for equipment needed thereby by rotating shaft 1 output kinetic energy again, thereby reach the purpose that fluid dynamic energy converts mechanical energy to.
Fig. 2 is the specific embodiments of the fluid kenetic energy converting device of half pocket type structure among the present invention.Fluid bag bracket 2 is that rotating shaft 1 is own in this example, and the fluid bag is directly installed in the rotating shaft 1 for half bag, and sack is that the center is towards unanimity with rotating shaft 1.This device is placed fluid, and fluid bag 3 is understood the absorption fluids kinetic energy and is spurred rotating shaft 1 rotation, thereby the kinetic energy of fluid is converted into mechanical energy output use.
Fig. 3 is controlled fast embodiment of the present invention.Fluid bag 3 covers are tied up on fluid bag bracket 2, are tied with support 5 in the fluid bag, and it is folding that support 5 can make fluid bag 3 be difficult for, and can open fast when opening; Stay cord 4 passes lacing hole 8 and ties up at fluid sack place, serial connection fluid bag buffering device 7 (as extension springs) in stay cord 4, and stay cord 4 the other ends are connected to speed-controlling device 6.This fluid kenetic energy converting device is placed fluid, and fluid bag 3 can the absorption fluids kinetic energy and drive rotating shaft 1 rotation, can dwindle the opening width of sack by stay cord 4 by speed-controlling device 6 when rotating speed is too fast, underspeed; Otherwise, to cross when rotating speed and can loosen stay cord 4 by speed-controlling device 6 when slow, the opening width of sack enlarges, lifting speed.Thereby constant speed to a certain extent is by rotating shaft 1 output kinetic energy.
