Abstract
The utility model relates to a bi-directional diving power generating gate dam built in the water of an existing reservoir area. The bi-directional diving power generating gate dam built in the water of the existing reservoir area can effectively solve the problems that utilization of existing reservoir water conservancy energy is insufficient and silt deposition in a tributary reservoir area is hard to extract. According to the technical solution, the bi-directional diving power generating gate dam built in the water of the existing reservoir area comprises a gate dam body, a group of bulb-type tubular turbine generators are installed in a dam foundation of the gate dam body, and gates are installed on the front faces and the back faces of the bulb-type tubular turbine generators. The bi-directional diving power generating gate dam built in the water of the existing reservoir area is novel, unique and capable of increasing existing reservoir installed power generating capacity, increasing generating capacity and promoting investment efficiency substantially.
Description
Technical field
The utility model relates to hydraulic engineering, particularly a kind of gate dam of two-way diving generating of setting up in the water of existing reservoir area.
Background technology
Water-power plant all is to set up at main stem, utilizing the height of water of swimming over to the downstream on the main stem that generator is installed generates electricity, generating is for unidirectional and irreversible, and because the both sides of main stem have the reservoir area, tributary of diverse location, in the reservoir filling process, silt in the main stem is brought in the reservoir area, tributary with retaining and deposits, the volume of reservoir area, tributary is constantly reducing, how utilizing the reservoir water level drop that disappears reservoir area, tributary riverway sludge is effectively washed away and to clear up, also is to need the problem that solves.
Summary of the invention
At above-mentioned situation, for overcoming the deficiency of prior art, the present invention's purpose just provides a kind of gate dam of two-way diving generating of setting up in the water of existing reservoir area, can effectively solve the problem that sedimentation is difficult to discharge in existing reservoir water conservancy using energy source deficiency and the reservoir area, tributary.
The technical scheme of its solution is, comprises gate dam, and one group of bulb-type tubular-turbine generator is housed in the dam foundation of gate dam, and gate all is housed on the front-back of bulb-type tubular-turbine generator.
The utility model is novel unique, and existing hydropower station installed capacity is increased, and generated energy increases, and efficiency of investment increases substantially.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Provided by Fig. 1, Fig. 2, the utility model comprises gate dam, and one group of bulb-type tubular-turbine generator 3 is housed in the dam foundation 2 of gate dam 1, and gate 4 all is housed on the front-back of bulb-type tubular-turbine generator 3.
The utility model in use, select tributary and main stem intersection appropriate location to set up brace type gate dam 1 in the reservoir area, this position should meet the following conditions: reservoir area, tributary upland water amount is less than 5% of reservoir area, tributary capacity, total generating duration of the scaled bulb tubular hydraulic generator of installing in reservoir area, tributary gate dam 13 should be greater than 3000 hours, and the mutual drop of water level of main stem and reservoir area, tributary just can generate electricity in time more than 2 meters.Scaled bulb tubular hydraulic generator 3 is installed in the dam foundation 2, and fluctuation in stage characteristic when utilizing the reservoir filling flood discharge artificially forms the inside and outside water level discrepancy in elevation of gate dam, generates electricity.Working as capacity as reservoir area, Xiaolangdi Dam Project coal pit ditch tributary is 1.5 hundred million m3, the total installation of generating capacity of scaled bulb tubular hydraulic generator 3 can reach 100,000 kilowatts, upland water amount in the reservoir area, tributary is less than 5% of reservoir area, tributary capacity, can ignore to the drop influence that disappears inside and outside the formation gate dam 1, when reservoir carries out retaining, the gate 4 of reservoir area, tributary gate dam 1 is closed, after rising to relative tributary reservoir water level to exceed 2 meters, the water level of main stem reservoir area forms drop with the reservoir area, tributary, this moment, silt was deposited in the main stem bottom, open the sluices 4 in good time, the water of main stem reservoir area enters the reservoir area, tributary by scaled bulb tubular hydraulic generator 3, can utilize scaled bulb tubular hydraulic generator 3 generatings, when reservoir area, tributary and main stem reservoir water level all reach peak level, the water of main stem no longer enters the reservoir area, tributary, closed shutter 4, work as reservoir spillway, the underwater, reservoir area of main stem drops to and opens the sluices after relative tributary reservoir water level is lower than 2 meters, water in the reservoir area, tributary sluices to main stem by scaled bulb tubular hydraulic generator 3 beginnings, can generate electricity again, so just realized two-way generating, two-way gross generation is not less than 6000 hours generating duration, about 600,000,000 degree of annual electricity generating capacity, can save 200,000 tons in mark coal, reduce 540,000 tons of CO2 emissions, electricity directly inserts national grid, and in this power generation process, the silt of main stem seldom flows to the reservoir area, tributary, to the not influence of storage capacity of reservoir area, tributary, when sluicing in the reservoir area, tributary, the silt at tributary inlet place is washed away.
The present invention is novel unique; existing hydropower station installed capacity is increased; generated energy increases considerably; and solved the problem of reservoir area, tributary silt sediment; increase reservoir service life, gross generation 600,000,000 degree are pollution-free sustainable energies, save a large amount of mark coals; reduce CO2 emissions, protected environment.
