Abstract

The hydraulic engine has reduced water flow speed and increased piston cross section area and stroke and thus less dynamic energy loss and high water energy converting efficiency. The rack block sliding with the rotation of the crankshaft in the horizontal direction perpendicular to the crankshaft drives the gear to transmit the motive force to water distributing block for rotating water distribution. When the piston is in the upper dead point, the water distributing block plugs up the water inlet and water outlet; and when the crankshaft rotates further, the rotating water distributing block makes the water outlet communicated with the water exhaust cylinder to produce work and exhaust water. The flywheel accumulates energy and the rotating main shaft outputs power via the speed varying planetary gear system.

Description

Double-cylinder waterpower engine

The present invention relates to a kind of high-conversion rate water energy converter structure.

In the prior art, the mode that water turbine utilizes impeller to take the water energy is divided into kinetic energy type, potential energy type and kinetic energy potential energy hybrid type.No matter any mode of taking, all be that the impact force of utilizing current to produce makes wheel rotation acting, flow rate of water flow big, thereby kinetic energy can't utilize fully, and utilization ratio is smaller, cause water can conversion ratio not high.

Task of the present invention provides and a kind ofly can satisfy flow and flow rate of water flow is little, and water can the high mechanism of conversion ratio.

The present invention is made up of working system, water distribution system and three parts of speed variator system.Piston, connecting rod, bent axle and cylinder body are formed working system.By increasing piston cross-section size and working stroke, can satisfy traffic requirement, and the acting number of times in the control piston unit time, can reach that flow rate of water flow is little, water flow dynamic energy is little, bigger than pressure energy, and the compressibility of water is minimum, when release pressure, energy loss is little.Because water pressure does work in locking system, utilize more fully, thereby can improve water energy conversion ratio.Speed variator system is made of equally distributed secondary planet train.Can make the gear compact structure on the one hand, the proof strength requirement can obtain bigger no-load voltage ratio on the other hand, and the acting number of times of piston in the unit time reduced.Water distribution system is made up of water distribution piece, gear, rack slide and bent axle, and it realizes in good time water distribution, satisfies the acting requirement.

The present invention is described in further detail below in conjunction with drawings and Examples.The figure medium scale is 1: 6, but does not comprise schematic representation.

Fig. 1 is main sectional view.

Fig. 2 is an echelon sectional view.

Fig. 3 is for removing the plan view after [3].

Fig. 4 is the worm's eye view of [3].

Fig. 5 and Fig. 6 are the planetary gear train schematic representation.

Fig. 7 is the plan view of cylinder sleeve.

Fig. 8 is plan view, left view and the plan view of water distribution piece.

Cylinder cap among Fig. 1 [3] and [4], water distribution piece [5], gear [9], rack slide [11] and bent axle [10] are formed water distribution system.Power passes to rack slide [11] from bent axle [10], passes to gear [9] again, and final gear [10] drives water distribution piece [5] and realizes rotation in good time and water inlet [1] is communicated with the draining cylinder with acting cylinder, water outlet [2].When piston is in upper and lower stop, water distribution piece [5] sealing water outlet [1] and water outlet [2], bent axle [10] rotates again, water distribution piece [5] beginning water distribution.The moving direction of slide block [11] is level and perpendicular to bent axle [10].Water distribution piece [5] is by the both sides that come axle of two quadrant symmetries, and its fan-shaped circumferential surface is just blocked the entry mouth of a river [1] and water outlet [2].Lid [3] and quadrant upper surface Spielpassung, lid [4] and sector unit circumference and lower surface be Spielpassung also, thereby water distribution piece [5] can be rotated, and prevents to leak and influences the acting effect.Piston is made up of two-layer, and skin is the high molecule plastic polyoxymethylene, and internal layer is that cast iron, connecting rod key seat are screwed on the piston internal layer.Cylinder sleeve is also made with polyoxymethylene, like this, both has been convenient to manufacturing, satisfies required precision, can utilize the polyoxymethylene friction factor low again, and its value is 0.15, and moisture absorption is little, and the advantage that dimensional stability is good reduces mechanical loss.

When the invention has the advantages that conversion water energy, the kinetic energy rejection of water energy is little, and the potential energy utilization is abundant, thereby water can the conversion ratio height.

Embodiment:

Piston radius is 200mm, stroke is 200mm, and the piston plastic layer is 30mm, and cast iron layer thickness is 10mm, the main shaft radius is 25mm, the water distribution tile height is 80mm, and segment angle is 90 °, and water distribution piece angle of swing is 60 °, the no-load voltage ratio coefficient of speed change system is 25, two sun gears, three pairs of planet wheels, one of them sun gear is fixed on the housing, and another and main shaft [18] are connected.By with hydrodynamometer test, head is when 5m-10m, and water can conversion ratio be 79.32%, and head is when 10m-20m, and water can conversion ratio be 80.29%, and when head is 30m when above, water can reach 81.03% by conversion ratio.
