Novel double-turbine tidal current energy generating device capable of self adapting tidal range

Abstract

The invention relates to a novel double-turbine tidal current energy generating device capable of self adapting tidal range. The novel double-turbine tidal current energy generating device comprises an upright post, wherein a sleeve matched with the upright post is slidably connected to the upright post, and a crane is arranged at the top of the upright post; a generator is fixedly connected withthe upper part of the sleeve, generator rotating shafts are symmetrically arranged on both sides of the generator, and generator gears are arranged at the ends of the generator rotating shafts; an upper floating body, a turbine supporting mechanism and a lower floating body are sequentially arranged on the sleeve from top to bottom, turbine rotating shafts are symmetrically arranged on the two sides of the turbine supporting mechanism, an assembling port matched with the sleeve is formed in the turbine supporting mechanism, and the turbine supporting mechanism is fixedly connected with the sleeve through the assembling port; turbines are fixedly connected with the ends of the turbine rotating shafts, and the turbines are in transmission connection with the generator gears through belts; anair inlet in communication with an annular tube is formed in the upper side portion, near one end of the upper floating body, of the annular tube, and the air inlet is in communication with the lowerfloating body through a vent pipe; and a water outlet in communication with the lower floating body is further formed in the bottom end of the lower floating body. The novel double-turbine tidal current energy generating device has the advantages that the novel double-turbine tidal current energy generating device is simple, reliable and easy to maintain, can realize the high-efficiency operationof the tidal current generator, and can realize the self-adaptive tidal range change of the power generation device.

Description

technical field [0001] The invention belongs to the field of marine energy, and in particular relates to a simple, reliable and easy-to-maintain novel tidal range self-adaptive dual-turbine tidal current energy generating device. Background technique [0002] The ocean energy reserves in the field of renewable energy are huge, and there are many forms of development, but there is still a long way to go before commercial operation. Relatively speaking, tidal current energy is one of the forms of ocean energy with the strongest regularity and the easiest development in the field of ocean energy. Among them, since the energy conversion efficiency of the horizontal axis tidal current energy generation system is significantly better than that of the vertical axis tidal current energy generation system, the horizontal axis tidal current energy generation system is more widely used. [0003] There are other invention patents for horizontal-axis two-way tidal current power generati...

AI Technical Summary

Problems solved by technology

The power generation system fixed by single pile foundation has a certain distance from the seabed in water, which cannot guarantee that the turbine is always in the best position and cannot adapt to changes in tidal range

Moreover, this fixed form is difficult to maintain, and every maintenance will cost a high price.
