Small floating power generation assembly

Abstract

The invention discloses a small floating power generation assembly. The power generation assembly is structured in the following manner: an electric generator is arranged at the center of the bearing part of the shell, the shaft of the electric generator is connected with the main vane outside the shell via a coupler, the upper space of the bearing part is filled with filler, the upper and lower ends of the shell are respectively sealed by an upper end cap and a lower end cap, the assisting vane is distributed in a uniform manner along the axial direction on the outer cylindrical surface of the shell, the main vane and the assisting vane are of the same shape-in the shape of circular curved surface but rotate in the opposite direction. Compared with the ordinary power generation assembly,the assembly in the invention can generate power while floating on the water and features easy installation, reliable structure and low cost; in addition the dual-vane structure and complete contact with the water flow enable increase of equipment power; what is more, the problem that the current floating detection sensor needs to be powered by storage battery and can only operate for a short span of time is solved and self-supply of power is realized. The small floating power generation assembly provides power for sensors in need of a small quantity of power, thus being capable of being usedin the wild and in the military field.

Description

technical field [0001] The invention relates to a power generation device, in particular to a small floating power generation device. Background technique [0002] There are a lot of existing small-scale power generation devices, but it can be found that the vast majority of them are mainly based on the main body of the device, fixed on the river bank, or fixed on the river pile, or fixedly connected to the ship and so on. In this case, the main body of the mechanical energy conversion device (generator) is stationary relative to the fixed object and thus relative to the earth, as long as the energy acquisition structure (such as various blades) obtains the energy of the water flow relative to the main body of the device Movement generates electricity. [0003] Small floating objects, such as military floating detection sensors, have limited power supply due to their long floating distance and long time, and will fail when the power supply is exhausted. Therefore, it is po...

Problems solved by technology

[0004] And the existing various power generating devices are obviously not power generating devices that can meet the above-mentioned purposes, because they are all fixed in the main body, and the floating device is small in size, and its whole is moving with the water flow. The key to realize the function is to make the energy capture device Relative movement with the main body of the floating object
