Title: Anti-drought and anti-flood by  still water circulation  generation

Description:
TECHNICAL FIELD 
     The anti-drought and anti-flood by still water circulation generation of the present invention is suitable for a region or a city and comprises following steps: digging a pit with 10-100 m depth or more near water, connecting a water turbine with a generator and placing at a bottom of the pit, opening a hole on the pit and releasing water of the pit as planned along a water discharge pipe to drive the water turbine at the bottom to rotate, connecting a blade and a chain, the blade and the chain are meshed with an upper gear of the pit and a lower gear of the pit, the upper gear of the pit is driven by an electric motor to drive the blade to rotate in a straight line on the water outlet pipe and in the water outlet pipe, so that the blade in the water outlet pipe moves upwards with water in a circulation manner. Carrying water driving the water turbine to rotate by the blade to be level with water of the pit or 10-50 meters higher than the water of the surface of the pit and power is generated again, and the discharging water is divided into circulation water, anti-drought water, and anti-flood water to be discharged, and if the discharging water is required to generate power circularly, turn off two channels as required, communicate, converge and restore the water with equal flow discharges, equal flow outlet and unequal flow velocity, the water is circularly released and circularly discharged, or the water is constantly released and constantly discharged, making the water turbine keep running at high speed and driving the generator to keep generating electricity, so there is no need for field power supply, electricity demand of a region or a city can be met without power supply from other places, and annual water consumption of an region or a city can be adjusted and controlled. If the total capacity of the local water lake and pit water and the total annual water consumption are estimated, the total capacity and total water consumption is assumed as not equal, then all the local water (processed water), rain, ice and snow melt water are brought to the lake and the pit, if it is not enough, river water is supplemented until the total capacity and total water consumption are equal. If there is a strong rainfall of 150-200 millimeters per hour, the sharp rise in water will cause floods, it is necessary to design a device for discharging 150-200 millimeters of water in an hour. If one device is not enough, then design more, in short, the water cannot be rose rapidly, and water usage of local residents needs to be guaranteed. 
     According to the requirement of electricity, a power station as large as the Three Gorges can be built along the Yangtze River per 30 kilometers, which requires no water interception and can be used to discharge water and generate electricity by digging a pit along both sides of the river, and has no effect on water transport and water discharge. It can be built along the lake, and along the coast. 
     BACKGROUND OF THE INVENTION 
     All the power generation industries around the world are now looking for resources to generate electricity, resulting in damage to the earth, environment and air pollution, harm to humans, excessive submerged land, excessive land occupation, and too much space occupation, even conflict and war. Nevertheless, the resources still can not meet the needs of human electricity consumption even if fully utilized due to limitation, especially human and material resources are consumed greatly. In order to survive, all humans have to face this situation, moreover, the world has no ability to complete control water disaster, although the mankind has taken many measures on the drought and flood problems, the effect is not significant. 
     SUMMARY OF THE INVENTION 
     In view of the shortcomings of the above-mentioned techniques, the purpose of the present invention is to provide anti-drought and anti-flood by still water circulation generation, which is used to replace various forms of power generation with limited still water and water, is able to meet the power generation demand of users and also capable of adjusting and meeting the local water consumption. The present invention is achieved by the following technical scheme: 
     Anti-drought and anti-flood by still water circulation generation, comprising: 
     digging a pit near water; when water of the pit is released, a certain force is generated; 
     releasing water; opening a hole on the pit and releasing the water in a planned way along a water discharge pipe to drive a water turbine to operate; determining a wheel size of a water turbine generator or length of a blade by local electricity demand by using a lever principle, distributing the water by using four or more than four pipes, releasing the water vertically, uniformly and evenly around a wheel of the water turbine generator or the blade, and driving the wheel or the blade to rotate at the most suitable angle; and 
     discharging water; carrying water driving the water turbine to rotate by the blade to be level with water of the pit, discharging the water as required by dividing into circulation water, anti-drought water, and anti-flood water, releasing and discharging the water circularly or constantly, and driving the water turbine to keep running at high speed and driving a generator to keep generating electricity. 
     The anti-drought and anti-flood by still water circulation generation, further comprising a water outlet pipe with a slope of 1:10 or different proportions from a surface of the pit to the bottom of the pit; the smaller slope of the water outlet pipe is, more labor-saving and better effect of the blade carrying the water; the water outlet pipe is tunneled from the bottom of the pit to the ground to reduce excessive use of the ground area. 
     The blade and a chain are connected with each other, the chain and the blade are meshed with an upper gear of the pit and a lower gear of the pit, the upper gear of the pit is driven by an electric motor to drive the blade to rotate in a straight line on the water outlet pipe and in the water outlet pipe, so that the blade in the water outlet pipe moves upwards with water in a circulation manner. 
     The discharging water is discharged at a position higher 10-50 meters or more than the water of the surface of the pit and power is generated again, and the discharging water is divided into three channels: circulation water (used to cycle in the absence of water), anti-drought water, and anti-flood water to be discharged, and if the discharging water is required to generate power circularly, turn off two channels as required. 
     Ice and snow are melted by electric heating in an alpine region, so that water flows circularly and generates power constantly. 
     A good river interception ensures smooth flow of water transport according to requirements of water transport, so that excess water can be discharged and deficient water can be supplemented timely. 
     The anti-drought and anti-flood by still water circulation generation, further comprising electricity and water, so that high pole erection and another channel for cross-regional long-distance transport are not needed. 
     The anti-drought and anti-flood by still water circulation generation of the present invention uses limited still water and water to generate power and anti-drought and anti-flood; it can replace and surpass the modern nuclear power generation, fire power generation, water power generation (water cutoff power generation), solar power, wind power generation and ensure sufficient power, it can infinitely replace and surpass the current use of electric pumping and resist drought, floods, and ensure that annual production and living water of local farmers and residents (except the tsunami and floods over the levee), and it can replace and surpass various uses of coal, natural gas and liquefied petroleum gas in the house of our country farmers and residents with low cost; it generates power and manages water simply, environmental friendly and high effectively; it can reduce the temperature of the weather, greatly reduce the extreme weather, protect people&#39;s health, and protect the natural ecological balance.
