Abstract

By using the equipment comprising a vertical cylinder, a gravity float, a non-return water valve, a cylinder bottom gate capable of opening and closing at regular interval and water outlet pipe, water is pressured from lower place to higher place by the buoyancy without needing any other power. The present invention makes it possible to save power, protect ecological environment and utilize natural resource fully.

Description

Utilizing hydraulic buoyancy is motive water level raising technology

A kind of hydraulic buoyancy is motive water level raising technology.The invention belongs to the waterpower application, be a kind of as explanation device shown in the drawings: vertically be fixed in the cabin by one and dive in cylinder body under water together with the hull major part, a gravity floating plug, cylinder bottom door, unidirectional water flowing valve and an outlet pipe that regularly opens and closes is formed.This device utilizes buoyancy of water (reaction force) to be motive force, intermittently hydraulic pressure in the cylinder is hoisted (if the logotype of many covering devices can produce lasting current) by the conversion of gravity floating plug, to reach the purpose of water level raising.This technology is mainly used in hydroelectric power; Or directly be used as power by all kinds of machineries of water wheels interlock; Or be used for irrigating.

Hydroelectric power at present mainly relies on builds a dam raising of water level, or utilizes the nature drop to carry out, and initial investment is big, and length consuming time also has certain influence to ecotope.The present invention is used for the middle and small scale hydroelectric power, can utilize all kinds of big-and-middle-sized vessel disposed of by scrapping transformations of the way, be fixed in any water surface and (must guarantee that the cylinder inner face is vertical with horizontal plane with certain depth, the center of gravity centre of buoyancy is on center line when guaranteeing that the gravity floating plug moves up and down, friction is minimum, and watertight is reliable), thereby investment is few, instant effect, income is big.Only large-area steel plate needs minute surface break-in, processing, assembling, alignment technique to have relatively high expectations, but has the technology of building ton water hydraulic press can guarantee that this device makes fast completely, and the present invention belongs to the our times various countries in fact and researchs and develops first choice of the new energy.Concrete working principle of the present invention such as Fig. 1 Fig. 2 are described as follows:

The condition that Fig. 1 obtains buoyancy (reaction force) is that water is touched in gravity floating plug bottom surface, and the buoyancy that makes progress (reaction force) equals gravity floating plug volume and multiply by proportion and add atmospheric pressure, because condition and result are variant with Archimedes' principle, so the title new theory.

Fig. 2 gravity floating plug volume weight is during more than or equal to outlet pipe overall height water column weight, and water will be by outside whole blow-off pipes in the cylinder.

After Fig. 3 gravity floating plug was pressed and fallen the cylinder bottom low level, the cylinder bottom door was opened, and the gravity floating plug obtains the outer buoyancy of water rising of cylinder (accumulation of energy).After gravity floating plug weight setting-out position drinking water balance, the cylinder bottom door is closed immediately, breaks contacts with the outer water of cylinder.And after the outlet pipe one-way cock is opened because the weight of gravity floating plug is more than or equal to outlet pipe overall height water column weight, and water (exoergic) in the pushing cylinder, the one-way cock through opening, with hydraulic pressure in the cylinder to eminence generating forebay.When the gravity floating plug pressed down, one-way cock was depressed by outlet pipe overall height water column weight and is closed extremely.Open the cylinder bottom door once more.The said process that moves in circles thus, just can be intermittently with hydraulic pressure in the cylinder to high-order, overlap logotype more, just can reach continuously hydraulic pressure in the cylinder to high-order, waste pipe impulsion hydraulic turbine generator generates electricity down in the forebay.

Specific embodiments of the present invention are decided on the depth of water and water surface width and required generation amount of power.The degree of depth and the width of the big or small Ying Yushui of this device adapt.Shallow as water, the water surface is narrow, device is big, can cause buoyancy not enough, device can not operate.As the depth of water, the water surface is wide, device is little, cause water buoyancy not make full use of, benefit is little.By a whole set of device rationally of its condition design.

Advantage of the present invention comes into plain view, and present technique has little, the instant effect of investment, for the development and use new energy have played effect.Play solid effect for preserving the ecological environment.Can reduce the hydroelectric power cost greatly.Find a new approach for making full use of the natural resources.

Claims

1, a kind of hydraulic buoyancy that utilizes is motive water level raising technology, and is main by the straight cylinder body of heavily fortified point, the gravity floating plug, and regularly the cylinder bottom door that opens and closes, one-way valve and water pipe are formed.

2, according to claim 1, this cylinder body, floating plug, cylinder bottom door one-way valve and water pipe can be made with the metal of any thickness according to the requirement of device size.

3, package unit as claimed in claim 2 is partly dived under water by being loaded in the cabin, and part is exposed to level, plays and utilizes buoyancy of water, and floating plug is pushed to eminence.Utilize floating plug weight greater than outlet pipe overall height water column weight water to be pressed to eminence by lower, complete unit can continuously operate repeatedly.
