Description

The method of intensive construction natural flow station and natural flow station that can intensive construction

Technical field

The present invention relates to the water generating technical field, specifically refer to a kind of method of intensive construction natural flow station and need not block to build a dam in the river and directly be installed in the hydraulic turbine and just can generate electricity on the water surface Can intensive constructionNatural flow station.

Background technology

The energy water of existing natural flow station utilization all is disposable; Be after water flows out from the power station; This water is just along flow through again tens of or hundreds of kms to next power station or flow directly into the sea of rivers; Can not block the river again because of the restriction of many-sided conditioned disjunction reason therebetween and build a dam and set up natural flow station, make limited water resource cause unlimited waste.

And existing natural flow station basically all is on rivers, to select suitable place to block the river to build a dam, and is installed in the hydraulic turbine under the water power dam with certain height of water, utilizes high drop, the high flow rate of water level to promote hydraulic turbine running generating.Consequently to take the good farmland and plough, move the immigrant, the big and influence ecological environment of construction cost.

Summary of the invention

The present invention provides a kind of method of intensive construction natural flow station and is different from existing water generating mode Can intensive constructionNatural flow station, intensive construction natural flow station in the suitable existing waterway of condition can make limited water resource obtain fully or utilization at double, and more can solve the part plains region has river waterflow but can not build the problem of natural flow station.

For this reason; The technical scheme that is adopted is: a kind of method of intensive construction natural flow station; With delivery port bottom line or the riverbed bottom line built or last seat power station is located is starting line; And with this line downstream square to the two lines going cross each other point place that extends to next section river course and flood season current waterline, can build a said natural flow station again; The highest safe water bit line before next gate of hydropower station is downstream square to bottom line that must not be higher than a last power station delivery port or riverbed bottom line.

A kind of natural flow station comprises the hydraulic turbine, generating set and connects both transmission mechanism; It also comprises first, second diversion gate; First, second bath gate, first, second divider wall and first, second gutter that forms by this first, second divider wall; Said first, second diversion gate and first, second bath gate are built the upstream extremity of river or inflow direction, river successively in, and said first, second divider wall is built the downstream of said first, second bath gate in; The said hydraulic turbine is located among first, second gutter, is connected with said transmission mechanism after the power transmission shaft of each hydraulic turbine that this is horizontal interconnects again.

When the present invention builds natural flow station in the existing waterway; The drop space of several meters or ten several meters between river course normal water flowing water bit line that utilization does not obtain for a long time utilizing except that flood season and the flood season waterline; Use the gate form; After normal water flowing water bit line is increased to the flood season waterline and forms maximum drop height water stream, be installed to the hydraulic turbine and make its running generating on the water surface.And when building the power station,, downstream square when the joining place of the flood season current waterline that extends to next section river course, can build a natural flow station again to build or the riverbed bottom line at place, last seat power station.By this principle; The suitable part rivers section of condition can be built one or several generated energy at thousands of kilowatts to tens thousand of kilowatts perhaps bigger kilowatt natural flow stations according to the difference of coming the water yield within thousands of meters distances; Build the generated energy of building power station afterwards, power station in according to the present invention and will approach to have built the generated energy in power station; And the generated energy in the power station that the front and back of intensive construction are adjacent is basic identical; Make that limited water resource obtains fully, utilization at double, more can solve the part plains region has river waterflow but can not build the problem of natural flow station.

The present invention utilizes the existing waterway to be directly installed on the hydraulic turbine on the water surface, and don't stops up the river course, and the polluted source environment more need not block the river and build a dam, do not take the arable land, good farmland, do not move the immigrant, and cost is low; Except that dry season, do not receive upland water amount size, water to rise and fall to influencing, and, can shunt by diversion gate when flood season comes the water yield bigger than normal basically according to the generated energy that how much increases and decreases that comes the water yield; Riverbank height gate can appropriate be increased in the part section when the surrounding enviroment conditions permit before within the certain distance, drop increases generated energy to flood.

The present invention is suitable for the large, medium and small rivers power station of building that utilizes water for producing electric power.
