Generator by using sea energy of low flow

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 ...

Problems solved by technology

However, judging from the products developed by Harbin Engineering University, their hydraulic turbine structure is not suitable for low-velocity subsea applications, and their work requires ocean current velocity V min ≥2.0~2.5m / s, the starting torque is large, not suitable for the conditions and environment of low water flow and sea energy in my country's coastal areas
