Abstract

A dam-free hydroelectric generation technology generates power by waterpower with no need of built dams, is non-destructive to water ecology and non-obstructive to fish migration, and is applicable on large scale and insusceptible to terrains. The dam-free hydroelectric generation technology generates power by impact force of river flows according to principle of Taijiquan and converts energy by changing motions. The dam-free hydroelectric generation technology provides a solution to dam building and investment problems of the prior hydroelectric generation. In the dam-free hydroelectric generation technology, waterpower acquired by specially made pontoons as stressed bodies are finally transmitted to generators to generate power through traction ropes by the maturest hydroelectric generator technology and pulley technology.

Description

Without the dam hydraulic power generation technology

Technical field:

Being exactly a kind of technology that utilizes water for producing electric power that does not need to build dam without dam water power technology, is a kind of Ecology that do not destroy, and does not hinder fish migration, the hydraulic power generation technology that is not subjected to the landform restriction that can large-scale application.The principle that this technology has adopted taijiquan is borrowed in generating with the impact force of river waterflow, receives one one and energy is changed among putting.

This technology has solved difficulty and the fund input of the construction dam of present hydroelectric power maximum, utilize the most ripe hydroelectric power motor technology and pulley technology, the waterpower of the pontoon as beaer of especial manufacture being caught by the traction cable finally is transmitted to the technology that generator generates electricity.

Background technique:

There has been rapid development in the epoch that hydroelectric machine technology, pulley technology, cable technology are maked rapid progress in present this new material technology.So that this is at power field, and the price of hydraulic turbine generator is the most cheap.And pulley and cable all are widely used in lifting appliance, and price also is very cheap compared to building dam, and except the stressed pontoon that needs especial manufacture, its cost all only is below 1/10th of present new energy equipment.

Summary of the invention:

This can have several different schemes without dam water power technology, specifically is suitable for according to the landform difference.This technology not only is applied to the river, also can apply to the ocean, only need to have relatively-stationary flow direction to implement, even current can change, also can by at once generating simply is set, not affect generating.

This is without the at first essential stressed pontoon of especial manufacture of dam water power technology, this pontoon is the structure of a hollow, only front end have one can folding gate be used for the power of letting out, when gate altogether, it is exactly a cup, the water that can hold tens tons even up to a hundred tons, the directional flow of these water will be accumulated enough energy at this stressed pontoon and be used for the pulling traction rope cable, rotation by pulley can be with the direction change of power, the other end at the traction cable is the another one weight, place the ground potential condition is arranged can be drawn to eminence with this weight, accumulates potential energy, gate one etc. stressed pontoon is opened, pontoon is stressed to be reduced, and potential energy is discharged, and energy can pass through gear, bearing or capstan winch are transmitted to generator and generate electricity.

Use this technology in the river that bend is arranged, the equipment such as pulley and capstan winch can be arranged on the land, near have height can be converted into these equipment directly can being set to of potential energy and exceed, if there is not natural highland, can builds high platform and form drop and accumulate potential energy.Can arrange in the river that also the another one buoyancy aid carries out the conversion of power, can reduce construction cost like this, this buoyancy aid does not need to have as especial manufacture the sort of the pontoon design of folding gate, only need to be that a stressed buoyancy aid that is smaller than stressed pontoon is just passable.

Do not have in the middle of the river or ocean of bend, just need in water, build a platform and be used for arranging the equipment such as pulley and power generating equipment, this platform can be the reinforced concrete construction of fixing, it also can be a fixing ship, this ship is in the situation that cast anchor and must can bear the traction of stressed pontoon and substantially do not produce displacement, the difference that depends on the complete equipment generated output, different power is also different separately to the requirement of this underwater platform.

As long as in the waters that current are arranged, this hydroelectric installation just can be by the relevant transformation production of generating electricity, it can not destroy and impact environment and ecological the generation, can maximizedly utilize water can carry out energy capture, is a kind of cheaply water power technology yet.Extraterrestrial except without the water source, any waters can develop, and can fundamentally solve the energy problem in the present whole world, can solve the various controversial issues that cause because of energy crisis etc.

Description of drawings:

Fig. 1 is stressed pontoon structural representation (side)

1, the hull of hollow is in order to guarantee that pontoon floats on the surface, perhaps to adopt foamed plastics to fill;

2, receiving sump, is for the cabin of taking in the water energy, under the impact of current, and the energy pulling cable conductance acting that the water among the cabin will be accumulated;

3, sluice gate can be led the water of receiving in the sump to fall off, and energy discharge will be so that the weight of pulley another side initiatively does work, and final so that Conversion of Energy is electric energy, folding is the most laborsaving up and down take axis as fulcrum for sluice gate.

Fig. 2 is stressed pontoon structural representation (front)

1, the hull of hollow;

2, receive sump.

Embodiment:

At first, choose current very fast, and have the river course of bend to use present technique, cost and benefit can be put into maximum.Generator, capstan winch, pulley and some other supplementary equipment can be placed on the bank, and reducing construction cost and reduce difficulty of construction on the one hand on the other hand, also is greatly to reduce to the maintenance difficulties in later stage.

Secondly, combine with a stressed pontoon that does not have an open-close type gate and the proprietary stressed pontoon of open-close type gate of present technique and carry out the conversion of energy be used to catching waterpower.

At last, select as much as possible the large hawser of pulling force and safety hauling capstan pedestal firmly, the restriction of generated output does not also lie in ground potential difference and the water velocity in river course, and is the on the bank strength of pedestal and the pulling force of hawser.

Claims (2)

1. be a kind ofly not need to build dam and just can utilize pulley, hawser and stressed pontoon that the current waterpower of directional flow in the rivers,lakes and seas is caught without the dam hydraulic power generation technology, carry out the technology of transformation of energy generating.

2. be to open an incompatible realization to the utilization of waterpower by one of stressed pontoon gate without the dam hydraulic power generation technology, the specific structure of this stressed pontoon determines the function that it is special.
