Abstract

The invention belongs to the technical field of new energy technology development and fluid power-driven power generation machines and provides a fluid power-driven machine, which is technically characterized by a movable baffle plate which can be immersed in fluid fully or by half in a transverse or vertical arrangement manner and clockwise or anticlockwise rotation manner, solves the problems of low flowing speed, low water head, low potential energy and incompetence of generating power, realizes power generation with building a dam and represents a new breakthrough in the field of hydroelectric generation. The fluid power-driven machine is not limited by a machine shell, has low investment cost and particularly, improves power generation efficiency by using the intercepting face of the movable baffle plate to do work and using the automatic opening of the movable baffle plate to eliminate the resistance to symmetric edges. The fluid power-driven machine can drive a generator to generate power in various kinds of natural fluid such as water in rivers and large rivers, stream, runoff, ocean current, tide, waves and the like or artificial fluid and can be used in large, medium and small power plants with low water heads. The machine is small in investment and floor occupation, avoids influencing natural ecological balance, allows for flexible layout adjustment, can be constructed quickly and is sustainable.

Description

The fluid force machine

Technical field

Moving, the mechanical device that potential energy is converted into electric energy that the present invention relates to that multiple natural fluid such as river, river stream, river stream, runoff, ocean current, morning and evening tides, wave or artificial fluid produced, affiliated new energy technology development hydroelectric power machinery technical field.

Background technique

The machinery of the low-head hydraulic of invention generating does not at present still reach the effect of the big flow generating of low water head, moreover can not in fluid, move in a circle its Total flooding, can only be disposed across in the fluid and can not place vertically, and can only change to a direction, and the present invention has solved the problem of above existence fully, can reach the purpose of the big flow generating of low water head.But Total flooding or partly flood in fluid during installation, can horizontal fluid in or perpendicular putting in the fluid, can be clockwise or commentaries on classics counterclockwise.When flow velocity was constant, the fluid force machine was done uniform circular motion, produced mechanical energy, and drove generator and produced electric energy.

Summary of the invention

The present invention mainly is main technical points with the sideboard, in the existing water engineer Total flooding water or be erected at and be difficult in the water move in a circle, and the present invention has utilized the throttleng surface of sideboard to regulate the resistance on symmetrical limit, the running that this machine of allowing does not stop along with flow velocity, the big rotating speed height of flow velocity, on the contrary rotating speed is low.

Description of drawings

Fig. 1 is the stereogram of the present invention when leaving standstill, and Fig. 2 is structure decomposition map of the present invention. The present invention is made up of eight major parts: main shaft 1; The arm of force (A, B) 2; The connecting ring 3 of the arm of force and main shaft; Change pulley 4; Sideboard 5; Sideboard and arm of force connecting axle, axle sleeve 6; Bearing and seat 7; Generator 8. The connecting ring 3 of main shaft 1, the arm of force 2, the arm of force and main shaft, change pulley 4 are linked together; The arm of force is made up of two steel pipes, an arm of force A is perpendicular to main shaft 1, another root arm of force B overlaps with the tangent line of annulus 3 with arm of force A top and intersects, A, the B intersection fills an axle, be connected with the bearing on the sideboard, the other end of sideboard connects in the same way, and form in twos symmetrical at main shaft, sideboard can fill 4 in the same way, 6, a plurality of symmetry blocks such as 8, make size according to fluid physical machine, can increase many group arm of forces 2, the arm of force is connected with sideboard symmetrical the fixing in the appropriate location of main shaft with the connecting ring 3 of main shaft, the width of sideboard is less than the length of the arm of force, sideboard can utilize special material to make, and is allowed to condition at the twice that buoyancy in the fluid surpasses own wt, and sideboard is placed on respectively same one side of the arm of force. The now explanation as an example of 4 baffle plates example is made as respectively a b c d plate. Allow the coupled arm of force closure of a plate, put into fluid, the two ends of main shaft are fastened on the pile body by bearing and bearing block, and fluid is the connected arm of force closure of b plate during perpendicular to a plate plate face; The vertical simultaneously plate face of the connected arm of force of c plate is parallel to the flow velocity direction of fluid; The connected arm of force closure of d. It is still closed when a arrives the d position; D opens during to the c position, and d plate and the vertical simultaneously plate face of self arm of force are parallel to the flow velocity direction of fluid; C is the connected arm of force closure of c plate during to the b position; B during to a position b plate plate face perpendicular to fluid. Take turns doing like this circulation circular motion that make and break is closed, make and break is closed, solved the resistance of Symmetry Edge when this machine moves in a circle in fluid. The present invention is not limited by casing, uninterrupted sideboard according to fluid can arrange the size that varies in size, reached the effect of easy enforcement, low cost, low friction, low water head, dynamical generating, reduced construct a dam, the wholesale costs of investment such as removal, the hydraulic turbine.

Embodiment

This fluid force machine is placed fluid, and vertical with the flow direction of fluid, the bearing support at two ends is fixed on pile body, and traverse or place vertically in fluid, but Total flooding or partly flood can change clockwise also and can also change counterclockwise.When rate of flow of fluid constant, wherein a baffle plate is closed and vertical with the flow velocity direction with the arm of force, and that the sideboard on symmetrical limit is opened is vertical with the arm of force, the plate face is parallel with the flow velocity direction, the fluid force machine begins to do uniform circular motion, quality m=(1/2) the ρ Lrv that bears on the fluid force machine baffle area this moment (annotate: L is that the long r of sideboard is that sideboard is wide), kinetic energy E=(1/2) mv^2 (annotate: ^2 represent square), potential energy E=mgh, action potential equates (1/2) mv^2=mgh, head h=v^2/2g.Quality on the sideboard produces mechanical energy by arm of force promotion main shaft under the effect of flow velocity thus, drives generator by change pulley and produces electric energy.With Three Gorges section flow velocity is example: establish V=3m/s, and L=50m, r=10m, the fluid force machine was done uniform circular motion when flow velocity was constant, quality m=(1/2) ρ Lrv=1/2 * 1000 * 50 * 10 * 3=750000kg of the water that bears on the baffle plate area; Head h=v^2/2g=3^2/2 * 10=0.45m; Kinetic energy E=(1/2) mv^2=(1/2) * 750000 * 9=3375000 Jiao; Potential energy E=mgh=750000 * 10 * 0.45=3375000 watt; If mechanical efficiency: 0.9; 3375000 watts * 0.9=3037500 watt; If electric work efficient: 0.9; So, effectively electric energy=3037500 watts * 0.9=2733750 watt/second; Can get thus, per hour the effective electric energy of output=2733750 watt/second * 3600 seconds=9841500 kilowatts/time, according to above example, this speculative investment is little, the usefulness height easily implements to be fit to build large, medium and small power station.
