Background
A great amount of flowing water bodies exist in the stream, the Yangtze river and the ocean, the kinetic energy stored in the flowing water bodies is extremely large, and if the flowing water bodies can be developed and utilized in a large scale at low cost, the carbon emission can be greatly reduced, so that offspring and descendants are benefited. However, the current major ocean current development is to build underwater windmills, such as horizontal axis lift type underwater windmills, vertical axis underwater windmills. The horizontal shaft lifting force type underwater windmill has high requirements on the water flow speed, generally not lower than 2 m/s, so that more low-speed water flows can not be fully developed and utilized. Moreover, because the density of the water body is extremely high, various types of underwater windmill blades bear extremely high water flow pressure, the windmill is heavy or extremely easy to damage, and a single underwater windmill is not easy to be enlarged; and the high-speed motion of the blade tip of the underwater windmill has great influence or damage on underwater organisms, so that the underwater windmill is not ecological. Moreover, the underwater windmill needs a large civil foundation or floating body, so that the investment cost is extremely high, and the underwater windmill has great influence on organisms on a riverbed and a seabed.
To this end, it has been proposed: the top ends of the parachute rope terminal umbrellas of a plurality of parachutes are sequentially connected in series on an annular rope or an annular chain according to the head-tail sequence, when water flows, the umbrellas moving against the water flow direction are folded and form a bundle, and the resistance to the water is extremely small; however, the umbrella moving along the flowing water direction is in an open state facing the water, and a rope or a chain, a chain wheel and a generator are pulled to generate electricity. However, the inventor of the present invention has found through research that the above-mentioned concept has major problems and disadvantages in that: how to wind the rope wheel or chain and the chain wheel or generator shaft by the water umbrellas which are connected in series on the annular rope or the annular chain does not have practical feasibility. Therefore, how to develop a novel hydraulic collection device which is low in cost and can develop and utilize advection micro-water energy in a large scale is necessary.
