Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the implementation of the present invention is described in detail as follows:

[0027] exist figure 1 Medium and low water flow sea energy generators are composed of sealing cover 1, hyperbolic platform 2, blade 3, guide vane 4, main shaft 5, thrust bearing 6, universal coupling 7, universal bearing 8, ring star speed increaser Device 9, generator 10 etc. parts constitute. There are several guide vanes 4 outside the circumference between the upper and lower hyperbolic platforms 2; the hyperbolic platforms 2 can be made of corrosion-resistant metal materials, and the 2 guide vanes, which are circular, elliptical or other shapes, are set up and down. 6-12 guide vanes 4 are arranged on the circumference of the middle edge by welding. The guide vane 4 is made of corrosion-resistant metal material, and is made of a flow guiding mechanical structure with the hyperbolic platform 2 at an angle of 30°-35° to the radial direction...

Abstract

Several guide vanes are set on surrounding places between top and bottom hyperbolic platforms of a low flow sea energy generator, with main shaft in central hole of the hyperbolic platforms and several blades mounted on the shaft. A generator is set at the shaft of the top hyperbolic platform and the two are covered with sealing hood separately, including: 1 the guide vanes and the blades are set to be the diversion structure along the cut angle of 30 deg.-35 deg. between the same direction and radio direction and sea flows at the same direction to blades.

Description

technical field [0001] The invention belongs to the category of generators, in particular to marine fluid generators. Background technique [0002] Ocean currents are natural phenomena in which seawater flows continuously in one direction. For example, the Kuroshio Current flowing along the eastern coast of my country has an average daily flow rate of 30-80 nautical miles, which is equivalent to 20 times the total flow of all rivers in the world. This shows that ocean currents contain huge energy. [0003] The theoretical estimate of the energy of ocean currents around the world is on the order of 100 million kilowatts. According to various observations and analysis data of 130 waterways and waterways along the coast of China, statistics and calculations show that the theoretical value of the annual average power of ocean current energy along the coast of China is about 14 million kilowatts. Among them, the sea current energy along the coasts ...
