Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not used to limit the scope of the present invention.

[0024] as attached Figure 1-3 As shown, an automatic opening and closing blade of a water turbine in the present invention includes an arc-shaped blade fan 1 and two arc-shaped blades 2 evenly installed on the blade fan 1, and multi-layer blades 2 can be installed on the blade fan 1 according to the actual situation. , preferably with 1-5 layers, the blade fan 1 is installed on the turbine shaft 4, 70% of the total area of ​​the blade fan 1 is in a hollow state, and the area of ​​the blade 2 is larger than the hollow area in the middle of the blade fan 1, so that When drafting, the blades can rely on the leaf fans, which can reduce the resistance of the water. A collar 9 is fixed on the leaf fan 1 in the middle of the two blades 2, and a lifting rod 3 is sleeved in the collar 9...

Abstract

The invention relates to the technical field of green energy source power generating equipment, in particular to an automatic opening and closing paddle of a water turbine. The automatic opening and closing paddle of the water turbine comprises an arc-shaped blade fan and a plurality of arc-shaped blades which are uniformly mounted on the blade fan, wherein the blade fan is mounted on a rotary shaft of the water turbine. The automatic opening and closing paddle is characterized in that a sleeve ring is fixed on the blade fan between two blades, wherein a lifting rod is arranged in the sleeve ring in a sleeving mode; a slide wheel is mounted on the bottom of the lifting rod; a plurality of semicircular rails which take the rotary shaft as the circle center are paved at one side, against water, of a lower water slot of the water turbine; each of the rail is in the shape of a crescent moon which is horizontal in middle and downward at two ends; and the blades are fixed on the blade fan by hinges. The automatic opening and closing paddle is novel in concept and unique in design; the automatic opening-closing paddle is adopted, so that the resistance force during rotation, against water, of the paddle is greatly reduced, and the water turbine can be wide enough and high enough, and is high in power generating capacity; and power generating power, which is obviously superior to that of current equipment of generating power by utilizing free water, of a power generating set of the single water turbine can reach about 10000 Kw.

Description

technical field [0001] The invention relates to the technical field of green energy power generation equipment, in particular to an automatic opening and closing blade of a water turbine. Background technique [0002] Under the influence of the external environment that energy consumption continues to rise and traditional energy sources are increasingly scarce, it has become an irresistible trend to explore and develop new energy sources. Ocean energy is a clean and environmentally friendly renewable energy. my country is a large ocean country with more than 3 million square kilometers of sea area and 18,000 kilometers of coastline. Ocean energy is rich in resources and has promising development prospects. At present, the main form of utilization of ocean energy is power generation. At the same time, there are more than 1,500 rivers with a drainage area of ​​1,000 square kilometers in my country. The runoff energy formed by the drop of river water is also immeasurable. Due ...
