Background

Enterprises such as electric power and energy firmly establish the concept of energy transformation and green development, technical innovation is increased, energy electric power is promoted from high carbon to low carbon, the pace of replacing petrochemical energy with clean energy is accelerated, and green production and consumption modes are gradually formed. The invention provides a double-anchor double-flow guiding barge and a power station for generating power by utilizing river water flow energy, and aims to exert the good desire of the whole people to participate in green energy construction and combine long-term marine engineering project management, basic level research and profound special thinking.

At present, green energy acquisition mode is comparatively numerous and diverse, and the technical maturity differs: the large wind power generation device is high in manufacturing and operating cost, high in technical requirement, high in installation and maintenance difficulty, long in effect period, capable of forming a huge and dead barrier for seasonally migrating birds and space eagles with strong desire, high in electricity price and not favored by users. The other green energy solar power generation device has large occupied area, and the energy loss of converting light energy into electric energy is large, so that certain light pollution is formed on the periphery. In the aspect of ocean wave energy power generation, certain attempts are made at home and abroad, mainly including three types of mechanical type, pneumatic type and hydraulic type, but the market application prospect is dim, large-scale construction cannot be achieved, and only the creative and experimental stages are remained.

The technology of the invention can also be used for large-scale construction of lower rivers of the power station which is already built and started in the great rivers. If the produced hydroelectric power station is in a full-load operation state, the downward water flow can form impact potential energy, and the potential energy formed by natural fall of the river reach can increase the water flow velocity by 9M/S meters and can drive a propeller with the diameter of 4 meters to drive a generator to generate 500 kilowatts, if a hydroenergy power station is simultaneously provided with 20 sets of water flow generators, the average power of 10000 kilowatts per hour can be generated, and the calculation is carried out by 0.46 yuan per watt, so that 110,400 yuan of RMB can be saved every day for the hydroenergy power station. By this calculation, a hydropower station can create 4029.6 ten thousand yuan of profit all the year round, and the construction cost can be recovered after the hydropower station is put into production for 4 years.

The invention is a continuous utilization of green renewable energy, the power source can not be exhausted, although the generated energy of a single hydroenergy power station has a certain seasonal change between the abundance and exhaustion of river running water, if the site selection is proper (geological conditions, the terrain of the river, the flow velocity of the running water and the water level drop), and the water flow supercharging effect of the double guide plates and a plurality of dragging type hydroenergy power stations which are arranged at a certain distance (the hull is positioned according to the flow velocity, and the distance between the two hydroenergy power stations is proper in 1 sea), the generated energy can be multiplied, the electric power of the plurality of hydroenergy power stations is tuned to a uniform parameter and then is merged into the national power grid. If the technology is applied in a large scale, immeasurable economic and social benefits can be generated, and the fresh water resource value of the great rivers in China is contributed.
