Abstract

The invention provides a floating-barrel type tidal current energy generating device which comprises a mooring system, a carrier and a water turbine / generator set. The floating-barrel type mooring system is used for mooring the carrier provided with the water turbine / generator set. The carrier is of a transversely-arranged door structure, wherein the door is shaped like a Chinese character 'ri'. The carrier comprises a streamline body, a personnel operating platform and a two-line water turbine / generator set support. The water turbine / generator set is used for converting motion energy of tidal currents into electrical energy and formed by connecting a water turbine, a generator and an accessory coaxial line in series. The water turbine / generator set is of a two-line contra-rotating type and is installed inside space of the carrier. The floating-barrel type tidal current energy generating device has the advantages that the floating-barrel type tidal current energy generating device does not need to be carried under a floating-type platform and on a pipe foundation or a tension leg, and therefore yawing force generated when the single-rotor water turbine operates is eliminated. Meanwhile, the generating device is simple in structure, low in production and manufacturing cost, convenient to install and maintain, economical, stable in generating performance, and suitable for being applied to a high sea state environment with rich tidal current energy.

Description

technical field

[0001] A buoy type tidal current energy generating device belongs to the field of hydraulic machinery and hydraulic generators. Background technique

[0002] With the development of the economy, the supply of fossil energy such as coal, oil, and natural gas is becoming increasingly tense, and the environmental pollution is intensifying. The development and utilization of green renewable energy has become an effective way to solve the current energy shortage and environmental pollution problems. As a clean and pollution-free green renewable energy, tidal current energy has the characteristics of large reserves, wide distribution, strong predictability, and low environmental pollution. At present, tidal current power generation devices are divided into base type, pile type and floating type according to the structural form of the carrier. Compared with the base type and pile type tidal current energy generation device, the floating tidal current energy generat...
