CN1800626A - Energy-saving power station - Google Patents

Abstract

The invention relates to an energy-saving power generator, which builds two opposite walls along the direction of river; builds a group of baffle walls whose ends in concave shape, and has several semi-round cuts on two sides, while the cuts contain upright water turbines; therefore, the power generation station can be divided into first and second group of power generators; the upper ends of two walls individually have several baffle blocks and sliding strobes extending to the upstream and in suspension points shape. The strobes can be switched according to actual condition to drive the turbine and drive the power generators. It is characterized in that: 1, it can be built at the positions with beach; 2, it has not hidden safety trouble to the downstream; 3, it can be used as several power generation stations. Therefore, it has reasonable design and significant social and economic benefits.

Description

Energy-saving power station

One, technical field: the present invention is a kind of modification hydroelectric power plant

Two, background technique: under world today's energy situation more and more in short supply, have only water just to possess the ability of regeneration.(coal can only be kept 200 years, and oil, rock gas have only the reserves in 60 years, the every degree of the electricity price of wind energy, solar energy, geothermal power high 0.50 yuan too expensive, select the user) how reasonably to skilfully use water be that we mankind face existence and the continuous key subjects of research and development.But, since the invention hydroelectric power, just merely utilized its deadweight to produce the impact force generating, and the inertia strength of having ignored, strangled each bar rivers to flow powerfully.So people produce in order to solve, the power station that needs of household electricity is also built higher and higher to build bigger and bigger.(see attached see 1.2), but correspondingly side effect is also increasing.Such as the flooding of: soil, house, historical relic, crowd's big resettlement, deposition of silt foreign material etc. and to the threat of downstream safety.As the factors such as artificial terrorist incident, war, landform variation that take place cause dam to collapse to collapse, and the downstream will be a vast expanse of water.Very select the utilization ratio of landforms, water also not high simultaneously, only account for 1/10th of energy consumption.The water that comes through innumerable trials and tribulations savings ground only with once just being over, is had to and rely on consume coal rich and influential family thermoelectricity to buying water season, cause the water power of China only to account for 17% ratio, very unfavorable to protecting the limited energy.

Three, summary of the invention: the present invention is through long-term observation and research, change the build a dam practice (seeing Appendix 1.2) of dark ponding of present spread eagle form height and make full use of the inertial impact force that great rivers flow powerfully and surge ahead, the object that changes the power station into following current and build, it has following advantage than the power station of spread eagle shape: 1, utilize existing riverbed, the water in summer toos many or too much for use at all and just allows its natural diffluence, winter, each gate closed, the water level that keeps summer at most only extraodinary flood amount (seeing accompanying drawing 1.2) need not flood the soil, the removal house, historical relic, evacuation crowds etc. greatly reduce engineering cost.(every year will be paid 5,000,000,000 yuan cost in the life of settling the reservoir area people in the power station, Three Gorges).2, extremely do not select landforms, as long as the place of beach mouth is arranged.This is to improving the utilization ratio of water, and increasing electric power is good approach.3, the length with the beach can increase generator set one station arbitrarily when multistation usefulness.4, the downstream is not possessed security threat,, there is not threat in the downstream yet even collapse to collapse because of water retention capacity volume of flood only.

Four, mode of execution: A, select the more rapid place of current (do not have beachhead can artificial beachhead) to go downstream to make up twice relatively to exceed the low wide and up narrow body of wall of long-term extraodinary flood figure place rice.B, in the abdomen of two walls, same along the downstream build again one tip be ploughshare mouth shape (and the distance between two walls be no more than the normal flow of buying water season such as Fig. 3 1. 6. 7.) there is the baffle wall of some semicircle breach on both sides, and whole power station is divided into the usefulness that first, second two generators group (Fig. 3 8.) prepares against maintenance.C, also have upstream the bank in the upper end of two walls respectively and extend star ... number dash block of wood and slide board type gate, the width of gate is can open the navigation or air flight just (see Fig. 3 3. 4.).D, at last with the length on beach in half garden v notch v of baffle wall, load onto vertical water turbine (Fig. 3 5.) according to buy, the discharge water water wheels that impact first group or second group of each slide plate gate of situation open and close both sides of flood just can drive a group of planes and generate electricity.The present invention has very high social benefit and economic benefit.

Description of drawings: Fig. 1 represents the side of full river big flood in summer, and at this moment the gate on both sides is all opened with flood discharge, and the width of its Y mouth and the width of water intake whenever increase and be twice flow velocity and just add and be twice, and are subjected to the resistance of slow river not influence the rotating speed of water wheels to guarantee water outlet.(and how many days in fact this situation does not account for yet, most of times are half river or Gu Shui.) Fig. 2 represents to buy the water side in season, though be Gu Shui, the water normal flow in season is bought because of inflow is lower than the whole piece rivers simultaneously because gate closes, and its water yield (position) does not subtract summer in both sides, can make the electric power maintenance electric weight in summer effectively.Owing to there is not the resistance of the slow river of water outlet, water wheels change more vigorously than summer in other words.Fig. 3 represents that whole engineering finishes, and the width that must note water intake when building is less than buying the water normal flow, and the width of turbine blade is less than the width of water intake, and the width of entery and delivery port equates.Here just the sign of Fig. 3 is done at length to introduce: 1. catadromous two bodies of wall.2. dash block of wood.3. floodwater releasing port.4. slide plate gate.5. vertical water turbine.6. water intake.7. water outlet.8. baffle wall.9. Y mouth, 10. current direction.

(this power station does not also have concrete specification now, and wide cut, beach according to each section in the implementation process afterwards are long, flow and deciding, and existing I also do not possess the knowledge of this respect, am willing to that the engineers and technicians to each electric power system learn in implementation process.Relevant data in the above-mentioned explanation is all from Chinese Central Television's news report).

Claims (2)

1, a kind of energy-saving power station, it is to mix the wall that earth builds up by the catadromous reinforcing bar in two sides, has some banks upstream to extend the sluice that blocks water block of wood and slide board type that is the ellipsis prismatic respectively in the upper end of two walls.Also have the one side termination to be ploughshare mouth shape in the corresponding centre of two walls, there is the baffle wall of some half garden v notch vs on both sides, and the breach the inside is vertical covering of the fan water wheels (1.2.3.5.8).

2, according to the feature of claim, can be in power generation process according to situation withered, flood, the sluice on open and close both sides carries out the generating of a plurality of electric power generator groups in single-group type ground on request.
