A represents Harbin Electric Machinery Factory in the model spectrum, CJ represents an impact (cutting) turbine, 237 represents the specific speed, W represents the horizontal shaft arrangement, 70 represents the pitch circle diameter of the 70 cm wheel and 1 represents 1. nozzle. , the jet diameter is 7CM
SF represents the hydrogenerator, W also represents the horizontal shaft arrangement, 800 refers to the generator rated power 800KW, 6 refers to the number of pairs of magnetic poles, 740. refers to the outer diameter of the top of the generator 740MM How to make a fish model have enough electrical energy or kinetic energy to swim upstream?
First of all, I forgive you for not understanding the principles of hydroelectric power generation.
To produce electricity, you need potential energy and kinetic energy. Moreover, theKinetic energy you mentioned is one of the energies. The water level is low and the flow is high. If we want to produce the same output, the speed of the unit will be very low and the size will be large. When we want to fully utilize the water resources of the river, the selected value. This model will exceed our human capabilities. For example, ultra-low speed and ultra-large size (theoretically exists). Our materials, structure and project cost can all exceed the standard. Either the extraordinary model cannot be produced or it cannot be exploited. Consequently, the development of a river basin is a matter of rational use of water resources. Make reasonable use of the potential and kinetic energy of water and choose a reasonable model. And to satisfy us as humans. And this cannot exceed our capabilities.
At present, the highest water height pcan reach more than 1,000 meters and the lowest can reach 1 to 3 meters. Different models are available. Every shape is also subject to structural constraints, and you don't have to be as big as you want. As small as you want. For example, for impact units, we only have 6 nozzles at most. For bulbs, the minimum water height is only around 2 meters, which is subject to certain technical restrictions.
It seems impossible to use the point of impact of the water to move the fish according to the situation you describe, because to generate electrical energy, according to the principle of hydroelectricity , water impacts the electricity production system. to generate electrical energy, and at the same time, the water flow acts as a resistance, that is, even if the fish is equipped with an electricity generating device, the electricity generated is generated in consomnant her own diet, therefore she. It is preferable not to install any electricity production device. So I agree with solar or the small generator mentioned above, but the most practical should be battery.
