Abstract
A facility and its method for generating electricity by using the tide belongs to the field of power generation characteristics are that it is composed of accumulation reservior, hydraulic generator and tail end reservior. Using the tide instead of heat energy to generate electricity can reduce generating cost about 40-60%, increase labor productivity 4-6 times, also it does not pollute environment.
Description
The invention belongs to power field, particularly a kind of hydroelectric power facility and electricity-generating method.
Tidal energy is a kind of cheap energy, and there is more than 20,000 kilometer shore line in China, is containing and is enriching tide energy, remains further to be developed, and makes full use of this natural resources, will accelerate the development of the national economy and development.Small-scale tidal energy development and use are only arranged at present, and the tidal energy of the cheapness of large-scale utilization green will be the human target of pursuing.
Purpose of the present invention designs a kind of large-scale tidal power generating equipment and electricity-generating method that utilizes tide energy to replace the heating power energy exactly.
The present invention realizes like this.Select tidal level difference section significantly by the sea, build a dam and build the storehouse, savings rise tidewater forms drop and promotes hydraulic turbine generator 4 generatings with potential energy.Facility comprises energy storage reservoir 1, inlet gate 2, pressure head water pipe 3, hydraulic turbine generator 4, draft tube 5, tail water storehouse 6, outlet gate 7.The shape in energy storage reservoir 1 and tail water storehouse 6 adopts garden shape, and this storehouse shape can strengthen the ability of opposing tide impact and increase the service life.The flashboard 12 of inlet gate 2 and outlet gate 6 adopts curvilinerar figure and the up big and down small shape outwards protruded, and is added with Stamping Steel Ribbon 11 at periphery, and this form can prolong flashboard can improve sealability again 12 working lifes.
Be to use like this after power generating equipment builds up, when use for the first time the back of going into operation the inlet gate 2 of energy storage reservoir 1 all opened outlet gate 7 Close Alls in tail water storehouse 5.When tidal level reaches the highest at the incoming tide, inlet gate 2 to be closed, the seawater of savings has potential energy in the energy storage reservoir 1, and seawater enters hydraulic turbine generator 4 through pressure head water pipe 3, drives hydraulic turbine generator 4 generatings, and tail water flows into tail water storehouse 6 certainly through draft tube 5.The second time after the operation at the incoming tide, when tidal level equals the water level of energy storage reservoir 1, inlet gate 2 is opened, when treating that tidal level reaches the peak, inlet gate 2 is closed, the outlet gate 7 in tail water storehouse 6 when tidal level equals the tail water reservoir level, is opened outlet gate 7 on the ebb the time, water in the tail water storehouse 6, declining and flow into the sea certainly with tidal level.Beginning is closed outlet gate 7 at the incoming tide, avoids seawater to blow back in the tail water storehouse 6.Circulation according to this, hydraulic turbine generator 4 uninterruptable power generations.
The invention has the advantages that it promptly has remarkable social benefit, has huge economic benefit again.With thermal power generation relatively, the one, free from environmental pollution, the 2nd, can reduce cost of electricity-generating, preresearch estimates, every degree electricity 50-60% that can reduce cost, labour productivity can improve 4-5 doubly.
Accompanying drawing 1 is the floor map of tidal power generating equipment
Accompanying drawing 2 is the longitudinal section schematic representation of tidal power generating equipment
Accompanying drawing 3 is the front view of gate sheet
Accompanying drawing 4 is the drawing in side sectional elevation of gate sheet
The lowest water level 13 of energy storage reservoir 1 of the present invention should ensure and make the hydraulic turbine generator 4 normal generatings of running continuously.The highest water level in tail water storehouse 6 should ensure the gravity flow of hydraulic turbine generator 4 tail water.The height of dam in energy storage reservoir 1 and tail water storehouse 6 should exceed 1.5 meters of maximum tidal level.Other facility and the conventional hydroelectric power plant in power station are basic identical, and difference is that some equipment facility should consider anticorrosion, and inlet gate 2 and outlet gate 7 have a plurality of, are common board-like gate.
