Description
The present invention is a kind of hydro-pneumatic hydraulic motor.This hydraulic engine utilizes the natural a large amount of current that continue the slowly motion cylinder that pushes the work forward.This clutch release slave cylinder is a double acting piston pump that is used for pushing highly pressurised liquid, in a common hydraulic-pneumatic two-phase pressure pan, highly pressurised liquid is adjusted to the pressure of regulation.Then, the Conversion of energy with this highly pressurised liquid in the underpressure chamber in a common blade mechanism is a mechanical work, is electric energy with the Conversion of energy of highly pressurised liquid in a generator that connects with it perhaps.
For thousands of years, hydraulic engine early is well-known.That this MU flows or from the energy that current produced that eminence flows down, promote various work mechanisms, particularly promote work such as mill and suction engine with it.In addition, also having a kind of equipment and device is that people are familiar with.They utilize the wave of seawater, and promptly by ebb tide with the periodic fluctuation in stage that produces at the incoming tide, perhaps the kinetic energy of the wave that also never stops in the ocean, boundary carries out work.
With the waterpower grinding machine of impeller-driven, still be used in many places today, although this old technological method more and more is counted as the just remnants of a kind of out-of-date technology of past tense in generation and a kind of souvenir of old mechanism.
In the hydraulic engine in generation, modal is the water turbine of various structure at the same time.In order to drive turbo machine, need high pressure and corresponding high water velocity.Such as, a common hydroelectric power station, its needed descent altitude, promptly the water-head between high water level and the low water level is greater than 200m.In order to reach desired height, and keep enough drinkable water reserves, must build reservoir dam, and the large reservoir in the common mountain valley.Adopt this method, in most of the cases can guarantee to obtain the good technical effect.Yet its shortcoming is, in the ordinary course of things, needs great amount of investment, and today paid particular attention to to catastrophic failure that environment caused.
The present invention is based on such task exactly, has created this hydraulic engine.It can utilize natural a large amount of flow energy of slow motion to meet the modern form that requires.
The working method of the hydro-pneumatic hydraulic motor of mentioning when this paper begins has solved being proposed of task.On fixing base weir dike, select a suitable position.A vertical casing is installed on this position.This casing, is connected with high water level and low water level by the closable communication port of closing means control by being positioned at weir dike next door.This communication port will have enough big cross section.In this casing or each casing, an enough heavy buoyancy aid is all arranged, it can be on the Vertical direction of casing free floating.This buoyancy aid mainly is to be bound up by a length-adjustable connecting rod and a liquid pump, and promptly the piston with clutch release slave cylinder is bound up.Clutch release slave cylinder is pressed into highly pressurised liquid as a double acting piston pump in pressure pan, thereby the piston of this clutch release slave cylinder mainly is that the liquid in the pressure pan is partly worked.The piston of clutch release slave cylinder can transmission power and motion on both direction.(generally speaking, on the highly pressurised liquid horizontal plane in the pressure pan some pressurized air always being arranged).The liquid part of hydraulic-pneumatic pressure pan links by the underpressure chamber of a catheter pressure and blade mechanism, so that eliminate the pressure of highly pressurised liquid.
In order to control this hydraulic engine, need a kind of device.It will have two to measure the switch that SEA LEVEL VARIATION is controlled closing means at least.
Other beneficial direction of the hydraulic engine of being invented is that highly pressurised liquid is to circulate in the system of a sealing.As the clutch release slave cylinder of double acting piston pump, when sucking, can connect by the water reservoir of suction pipe and turbomachine underpressure chamber.This water reservoir is used for collecting post-decompression liquid.
The motor of being invented can will slowly move, or the flow energy that flows down from eminence lentamente is converted into mechanical work (rotation motion of the live axle of corresponding moment of torsion is arranged).Generate electricity if turbomachine and a generator be bound up, will prove that this hydraulic engine is extraordinary.Turbomachine promptly can be a turbo machine like this, also fluid motor.
Common hydraulic oil or the water that has added proper additive all can be used as highly pressurised liquid, because they have enough lubricities, and not quite bubble easily.Certainly, should note avoiding occurring corrosion this moment.
From the above-mentioned actual characteristic of the new hydraulic engine invented, as if can see, as long as the water-head of 1-2 rice is arranged, just can make this machine run fully, can reach the pressure of the desired highly pressurised liquid of machine works without difficulty: 6 to 10KP/cm
2Fixed value.This numerical value is very desirable for hydraulic engine.
In addition, by inventing this method, also available lubricity is good, and gets rid of fully because of wearing and tearing cause the highly pressurised liquid of impurity and directly drive fluid motor, to drive generator for electricity generation.Simultaneously, the efficient of this fluid motor is than the high several times of efficient of turbo machine.
The particularly advantageous purposes of the present invention at first refers following several characteristic:
The hydraulic engine of being invented can be below the high water level in surperficial waters, near the particularly following running of dykes and dams of the high water level in river.Therefore, embankment system that can be special.Like this, just can keep the physical environment in river, thereby also just not have the danger that destroys environment.
This invention can utilize the big and energy in the river that water-head is little of the water yield.Simultaneously, it also can utilize by what the fluctuation of seawater tide formed has only the very little of one to two meter water level, and clocklike the kinetic energy of wave obtains energy.
This hydraulic engine also can turn round under the situation of water level alternate.In other words, work under the situation that it can often change in the high water level and the low water level on the Yan Di both sides of being built.Therefore, in principle, open up a kind of periodic wave that utilizes, promptly utilized the new way of the energy that the seawater plane rises and falls in the periodicity of the fluctuation time of tide.
For the hydraulic engine of realizing technically being invented, do not need new or for this purpose and the special material and the new process of development.The whole constituent elements and the parts of machine can use and use decades in industry, and widespread production and the parts that live through testing make.
As an entity or integral unit, build the hydraulic engine of this invention and the required investment of energy production system seldom, and be safe from danger.This mainly is because its desired retaining is highly very low.
About the essence of the hydraulic engine invented, method of work and further feature will be done more detailed explanation according to institute's accompanying drawing in the topology example below.
