Embodiment 2

[0055] Please refer to Figure 5 , Figure 5 It is a structural schematic diagram of another vertical axis tidal current energy generating device of the present invention. This embodiment is basically the same as Embodiment 1, the difference is that there is no anchor chain fixing frame 3, bearing bracket 4, and bearing 41 in this embodiment, and the whole device is simple in structure and easy to operate; the whole device is placed under the object floating on the water surface , such as a ship. During use, pull down anchor chain fixing frame 3, it is fixed on the below of buoyant body again.

Embodiment 3

[0057] Please refer to Image 6 , Image 6 It is a structural schematic diagram of another vertical-axis tidal current energy generating device of the present invention. This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, a total of two vertical axis power generation devices are selected, and the array is placed on the seabed where the tidal current energy passes to form a power field, wherein the number of vertical axis power generation fields in the array is different. Limitations and the number in this embodiment, the number of vertical axis power generation devices can be selected according to needs. This device can supply power for off-shore and off-grid lighthouses, buoys and other devices, and can also form an array and be fixed on the seabed or lake bottom where the tidal current can pass. Generate electricity and provide clean energy for electrical equipment.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of marine renewable energy, in particular to a vertical axis tidal current energy generating device and its application. Background technique [0002] As a clean and pollution-free green renewable new energy, tidal current energy has the characteristics of large reserves, wide distribution, strong predictability, and low environmental pollution. The development and utilization of tidal current energy has important practical significance for alleviating energy shortage and reducing environmental pollution. The main form of tidal current energy utilization is to use the tidal current energy generating device to generate electricity. The principle is: the tidal current energy impacts the water turbine and converts the kinetic energy of the tidal current energy flow into the mechanical energy of the water turbine. The water turbine drives the generator to generate electricity through ...
