Abstract

A hydraulic mechanical equipment uses the electric energy to control the on-off of a valve and change the flow direction of water. The work principle is that the unbalanced bottom pressure of a quasi-communicating vessel structure forces the shape of a deformable piston with a special structure to turn to an empty drum shape from a canister wall shape; consequently the water level can be heightened. The equipment comprises the deformable piston, a shell of the quasi-communicating vessel structure, a water inlet, a water outlet, an air duct and an electric valve. The deformable piston is arranged in the main shell of the quasi-communicating vessel structure and is divided into two parts. The upper part of the piston is a canister with bottom but without cover and the lower part of the piston is provided with the valve. The lower part looks like an erected barbell. Both an upper bottom and a lower bottom are provided with valves. Under the action of electric control, the valve can be opened or closed. The water flow is utilized to regulate the external pressure. The shape of the deformable piston can change between the canister wall shape and the empty drum. The piston can also floatupward or sink in the main shell of the quasi-communicating vessel structure to lift the natural water level to a certain high level. The invention has the advantages of energy saving, environmentalprotection and high efficiency of water lift, which can replace the prior man-sized water lifting station.

Description

The buoyancy water lifter of connecting vessel structure similar

Technical field

" buoyancy water lifter of connecting vessel structure similar " that the present invention proposes, be the Push And Release that utilizes the small amount of electrical energy control valve, thereby flowing and termination of control water utilize the principle of connecting vessels bottom pressure equilibrium again, and the occurring in nature buoyancy phenomenon, water is carried to eminence from lower.The invention belongs to the technical field of water conservancy machinery facilities and equipment type exploitation.

Background technique

The imbalance of water resources has restricted the development of national economy, has a strong impact on few water area people's life, production, jeopardizes people's living safety, and country throws huge fund energetically down and implements the south water to north, and the equilibrirm water resource is the very important decision that country realizes long-term stability.At present, the south water to north adopts multistage pump station, utilizes electric energy or mechanical energy to promote water pump, and water is carried to eminence from lower, carries as for the few water area of drought again.This method advantage is a technology maturation, and shortcoming is that investment is big, and power consumption is high, and usefulness is low.Also there is patented technology to utilize a part of water falling gravity to produce power, driving water lift equipment promotes another part water, examples " the automatic water elevator of conversion, unit, a group of planes fall into water " etc., Chinese invention patent number are 02129275.5,200510075084.6, all are to adopt this method.The advantage of this class patent is that equipment is simple, but two big drawbacks are arranged, the one, building the place has bigger narrow limitation, positions such as the reservoir that the height of water was bigger about it must be built in, dam, and water from up to down flows and could produce enough power with the upwards lifting of another part water; The 2nd, water lift efficient is low, do not consider any friction or energy loss, suppose 50% fall and other 50% water can be promoted under water, the lifting of first order water is than being 50% of Total Water, if adopt said method to continue to do the second level and promote promoting 50% the water of getting on, then promotes the water yield and has only 25% of Total Water, if do third level lifting, then reduce to 12.5%, every increase one-level, the water yield of lifting is drop by half then.

Summary of the invention

Goal of the invention: for overcoming existing extracting water facility equipment energy consumption height, usefulness is low, the place to use is limited to deficiency, the present invention splits channel in addition, utilize the pressure balanced principle in connecting vessels bottom, use the eternal buoyancy of occurring in nature,, promote than big water quantity with less controlling electric energy, energy-saving and environmental protection, simple in structure, as long as there is water just can use, be not subjected to the restriction of geographical environment, to reach energy-saving safe, water lift is many, efficient is high purpose.Material required for the present invention is common, and is simple in structure, is easy to safeguard that rate of fault is low, can replace existing large-scale extracting water facility equipment fully.

Technological scheme: basic principle of the present invention is a connecting vessels base pressure balance, the liquid that adds in connecting vessels as shown in Figure 1 is nature water, the connecting vessels left side is below natural water level, have abundant water resources, the proportion of putting into a total volume weight bottom the right side is 0.1 movable hollowing shape piston, and then there is the discrepancy in elevation in connecting vessels both sides liquid level.Suppose that depth pistion is 20 meters (it is high 2 meters that weight is equivalent to water column), according to pressure balanced computation rule, the liquid level on right side will exceed 18 meters of left side liquid levels.If (17 meters of example) opening under the liquid level of right side is derived right side liquid, then, the connecting vessels base pressure is uneven again, and left side pressure is greater than right atrial pressure, and unbalanced pressure forces hollowing shape piston come-up and right side liquid to continue to flow out, and forms fluid.Like this, this structure is equivalent to liquid has been improved 17 meters.If float to liquid level top, right side at hollowing shape piston, by control hollowing shape piston being become barrel shape piston, and make piston sink down into the right side liquid bottom, is empty because of barrel shape piston is middle, so do not influence flow of fluid in sinking, in the bottom, allow barrel shape piston become hollowing shape piston again, proportion is still above mentioned 0.1, like this, because of pressure imbalance, hollowing shape piston come-up in right side promotes 17 meters highly follow-up afterflows with the liquid that promotes the connecting vessels right side and goes out.And so forth, this water lift motion will form continuous current.

Key of the present invention is to make Deformed piston, promptly allows barrel shape piston become hollowing shape piston by control, conversely, floats to liquid top at hollowing shape piston, becomes barrel shape piston by hollowing shape piston by control again.This piston mainly is divided into the two large divisions, and the one, piston top, the 2nd, piston bottom.The shape on piston top is a cylindrical shell that end uncovered is arranged, and design has the hole and the electric control valve of conducting on the bottom surface, and the valve of bottom surface can be by automatically controlled formation conducting or closing state.During the valve conducting, a cylindrical shell is then formed at piston top, and liquid can be from top to bottom or free-flow from bottom to top, and during valve closing, liquid can not flow up and down.The barbell that piston bottom likeness in form weightlifter uses, be divided into upper base, push rod, go to the bottom, push rod is by the hole of piston top conducting, can drive the upper and lower end moves up and down, electric control valve is all arranged at upper and lower the end, and during the valve conducting, liquid can be from top to bottom or free-flow from bottom to top, during valve closing, liquid can not flow up and down.

The principle of Deformed piston distortion is: the one, and barrel shape piston becomes hollowing shape piston.At default position, connecting vessels bottom, 3 groups of valve Close Alls of piston top and bottom, add one in the left side of connecting vessels and start water column, the pressure of water is oppressed going to the bottom of Deformed piston bottom by the bottom of connecting vessels, making goes to the bottom promotes upper base by push rod, and whole piston bottom moves up along piston top barrel, imports air simultaneously from the outside, when going to the bottom of piston bottom closely contacted with going to the bottom of piston top, barrel shape piston had then become hollowing shape piston.Hollowing shape piston can upwards float according to principle mentioned above, floods.The 2nd, hollowing shape piston becomes barrel shape piston.Hollowing shape piston floats to liquid top, by automatically controlled, 1 group of valve on Deformed piston top, 2 groups of valves of bottom are all opened, and liquid is free-flow from top to bottom, air in the Deformed piston can be substituted by water like this, and hollowing shape piston then becomes barrel shape piston.Because of the proportion of making the Deformed piston material greater than water, Deformed piston can sink down into default position, connecting vessels bottom by liquid top owing to the gravity reason, waits for that next round barrel shape piston becomes the generation of hollowing shape piston control.Go round and begin again like this, Deformed piston constantly becomes the hollowing shape by the barrel shape, and come-up improves liquid level, becomes the barrel shape by the hollowing shape again when the liquid level top, sinks down into the connecting vessels bottom, waits for becoming hollowing shape come-up once more.

Controlling method of the present invention is to utilize the unlatching of valve or close, and the flow direction and the pressure of control water, thereby the variation of control modification piston between barrel shape and two kinds of forms of hollowing shape to reach come-up, promote the purpose of liquid.

Beneficial effect: the present invention can have the place at water source to use any, does not need generation power such as flowing water drop, and not loss Total Water can be increased to the natural water surface another higher level, flows to the place that needs to use the water source by drainage catheter or irrigation canals and ditches again.Suppose dark 200 meters of connecting vessels, height was 20 meters when Deformed piston was hollowing shape piston, and height then is 40 meters when being barrel shape piston, 160 meters of water lifts of then every operation, and deduction starts 20 meters in current, 140 meters of each clean water lifts.If the piston head area is by 20 square metres of calculating, piston moves 100 times every day, and then this equipment can improve 17 meters with the water of 280000 cubic metres (140 * 20 * 100) in one day, strengthened equipment size, and then the water lift amount is bigger.If multiple devices paired running, water lift amount will be very large.If adopt the mode of multistage water lift, the present invention can improve the height of the water surface in theory arbitrarily, and service society promotes the well-being of mankind.If in the south water to north that country implements, use the present invention, substitute all pump stations, the energy-saving effect highly significant, can produce beyond measure economic and social benefit, might make the desert become the oasis, have the whole world in view, might make very thirsty Africa become the silo of weed fertilizer water U.S..

Embodiment

Fig. 1 is a principle schematic, illustrates that hollowing shape piston 6 in connecting vessels main casing 5, can flood.Mode of execution is: water intake 2 is below the natural water surface 1, the nature water surface 1 flows into connecting vessels pressure regulation housing 27 by water intake 2, in the main casing 5, the connection mouth of intercommunication is arranged at pressure regulation housing 27 and main casing 5 bottoms, hollowing shape piston 6 is assemblied in connecting vessels main casing 5 bottoms, if hollowing shape piston 6 total volume proportions are 0.1, proportion 1.0 much smaller than water, if 20 meters of hollowing shape piston 6 height overalls, according to connecting vessels base pressure equilibrium principle, the water surface of connecting vessels main casing 5 will be higher 18 meters than the natural water surface 1, the water surface 3 after promptly improving exceeds 18 meters than the nature water surface 1, if a water outlet 4 is opened at 1 meter of water level 3 downsides after raising, water after improving is drawn, then the connecting vessels base pressure is uneven again, the pressure of pressure regulation housing 27 bottoms is greater than the pressure of main casing 5 bottoms, and unbalanced pressure forces hollowing shape piston 6 come-ups, promotes in the connecting vessels main casing 5, the water on hollowing shape piston 6 tops continues to discharge from water outlet 4.

Fig. 2 is the Deformed piston structural representation, and this piston can change between hollowing shape piston 6 and barrel shape piston 26 two states under control.Mode of execution is: Deformed piston divides two-part up and down, and being gone to the bottom by upper body 7 and top and 8 forms in top, is provided with ventilating hole 9 on upper body 7, on going to the bottom on top valve B15 is installed, and is reserved with centre hole 10 in the middle of going to the bottom on top.The bottom of Deformed piston is as a barbell that erects, and it is gone to the bottom by bottom upper base 11, push rod 12 and bottom and 13 forms, and valve A14 is installed on bottom upper base 11, and going to the bottom in the bottom is equipped with valve C16 on 13.During assembling, bottom upper base 11 is packed in the upper body 7, and the position and can drive push rod 12 and moves freely in upper body 7 above ventilating hole 9.

If valve A14, valve B15, the valve C16 Close All of Deformed piston upper and lower part, the bottom of Deformed piston is upwards promoted by the external force effect, to bottom upper base 11 and position, upper edge, the bottom of upper body 7 go to the bottom 13 with top go to the bottom 8 contact after, this Deformed piston promptly becomes hollowing shape piston 6.The material proportion of making Deformed piston is assumed to be the high strength alloy material greater than water, and material proportion is between 2～4, but after becoming hollowing shape piston 6, according to total volume and total weight, its proportion promotes the strength that water level rises much smaller than water so it can float to produce.

If valve A14, valve B15, the valve C16 of Deformed piston upper and lower part all open, then water can flow in the Deformed piston upper and lower part by valve, and promptly Deformed piston has become barrel shape piston 26.Because of this piston Manufacturing material proportion greater than water, behind the valve open, liquid can be upper and lower flows, so barrel shape piston 26 can sink down into default position, connecting vessels bottom.

Fig. 3 produces the buoyancy schematic representation, and it can make Deformed piston become hollowing shape piston 6 come-ups by barrel shape piston 26.Mode of execution is: Deformed piston is barrel shape piston 26 and is assemblied in default position in the connecting vessels main casing 5, be fixed at the bottom of connecting vessels main casing 5 by bottom clamp 24, piston upper body 7 can not move, and the piston bottom can move up and down by the connection of push rod 12; Ventilating hole 9 designs fix are gone to the bottom between 8 at Deformed piston bottom upper base 11 and top, link to each other with breathing pipe 21 through breathing pipe switch 22, and seal waterproof; Deformed piston top go to the bottom 8 with pneumostome 23 suitable for reading flushing, do not establish valve on the pneumostome 23, water can be from the natural water surface 1 by connecting vessels auxiliary shell 28 turnover pneumostomes 23, if connecting vessels places very dark natural water, periphery is surrounded by water, and then connecting vessels auxiliary shell 28 can omit; The bottom goes to the bottom 13 on the top of main casing 5 with pressure regulation housing 27 connection mouths.During enforcement, throttle down A14, B15, C16 open breathing pipe switch 22, throttle down D17, open valve E18, throttle down F19, open valve 620.Then improve the back water surface 3 by valve E18 and connecting vessels pressure regulation housing 27, acting on the piston bottom goes to the bottom on 13, exceed the nature water surface 1 because of improving the back water surface 3, so the piston bottom moves up under the effect of pressure, the piston bottom go to the bottom 13 and the top water of going to the bottom between 8 flow to the nature water surface 1 by pneumostome 23, auxiliary shell 28.When push rod 12 moves up, because of valve A14, B15 close, form a negative pressuren zone between 8 so go to the bottom in piston bottom upper base 11 and top, outside air then inwardly replenishes by breathing pipe 21, breathing pipe switch 22, ventilating hole 9.Under the effect of piston bottom push rod 12, piston bottom upper base 11 moves up along piston upper body 7 inwalls, and the water in its upper body 7 flows to the nature water surface by valve G20.

Have the discrepancy in elevation because of improving between the back water surface 3 and the natural water surface 1, so among Fig. 3, the piston bottom is moved on can be continuously, to the piston bottom go to the bottom 13 when going to the bottom 8 tight contacts with top till, piston promptly becomes hollowing shape piston 6 like this.

Fig. 4 is the operation schematic representation, and during operation, hollowing shape piston 6 can be brought up to water and improve the back water surface 3 from the natural water surface 1.Mode of execution is: after Deformed piston becomes hollowing shape piston 6, close breathing pipe switch 22, throttle down E18, open valve D17, throttle down G20, open valve F19, unclamp the bottom clamp 24 of fixed piston afterwards, because the floating function of connecting vessels pressure and hollowing shape piston 6, the current on connecting vessels main casing 5, hollowing shape piston 6 tops are through valve F19, be pushed into the zone of improving the back water surface 3, to realize the function of water lift.By operation, hollowing shape piston 6 can float to the top of connecting vessels main casing 5 always.

Fig. 5 is the sinking schematic representation, and by control, it can make hollowing shape piston 6 become barrel shape piston 26, sinks down into default position, connecting vessels main casing 5 bottoms.Mode of execution is: hollowing shape piston 6 floats to connecting vessels main casing 5 liquid level tops, control top clamp 25 fixed piston upper body 7, make it and to move, then, throttle down F19, open valve G20, valve D17, E18 state are constant, be respectively the opening and closing state, again, open valve A14, B15, C16, like this, the air of going to the bottom between 8 in piston bottom upper base 11 and top leaks by valve A14, valve G20, simultaneously, the space after the water in the natural water surface 1 is also filled up air and leaked by valve G20, valve A14.After valve A14, B15, C16 open, water by valve can be in piston on current downflow, the piston upper and lower is all filled up by water, because of the proportion of making piston material greater than water, after unclamping the top clamp 25 of control piston upper body 7, Deformed piston can be preset the position in free subsidence to connecting vessels bottom.

Fig. 6 is the schematic representation that flows to of water, represents the flow direction of water with the lines of band arrow.Fig. 6-the 1st is when Deformed piston produces buoyancy (Fig. 3) state, improve the water of the back water surface 3 and go to the bottom 13 to the Deformed piston bottom by valve E18, the bottom go to the bottom 13 and the top water of going to the bottom between 8 flow to the nature water surface 1 by pneumostome 23, the water in the Deformed piston upper body 7 flows to the nature water surface 1 by valve 620; Fig. 6-the 2nd is during Deformed piston operation (Fig. 4) state, water in the nature water surface 1, enter main casing 5 by valve D17, connecting vessels pressure regulation housing 27, nature water also can be supplemented in the connecting vessels main casing 5 by pneumostome 23, hollowing shape piston 6 come-ups, with in the main casing 5, the water on hollowing shape piston 6 tops pushes by valve F19 and improves the back water surface 3, to realize the water lift function; When Fig. 6-the 3rd, Deformed piston sank (Fig. 5) state, the water of the natural water surface 1 flowed in the Deformed piston by valve G20, with the gas in the exchange Deformed piston.

Above Fig. 1 to Fig. 6 is the process of a water lift of the present invention, only needs circulation to go down, and will constantly water be promoted to from the natural water surface 1 to improve the back water surface 3, and purposes is very extensive.Energy consumption only is the employed electric energy of switch valve in using, so very energy-conservation.
