Technical Field

Background

The wind power generator is an electric power device which converts wind energy into mechanical work, and the mechanical work drives a rotor to rotate so as to finally output alternating current. The site selection of the wind driven generator mainly considers the stability of the annual wind power, and the upper part of the sea does not have any shielding object, so the annual wind power is stable, and the wind driven generator is very suitable for erecting. However, as people have frequent activities on the sea, more and more marine garbage starts to appear, and the flooding of the marine garbage causes serious damage to the marine ecological environment.

In order to solve the problems, Chinese patent CN 107191332A discloses an offshore wind driven generator capable of removing sea surface garbage, which comprises a sea bottom anchor, a support column, a base, a tower barrel, a power generation mechanism and a cleaning mechanism, wherein the power generation mechanism comprises a driving component and a power generation component, the driving component comprises a first rotating shaft, a flange plate, a blade and a first gear, the power generation component comprises a second gear, a second rotating shaft, a gear box and a generator set, the cleaning mechanism comprises a power component and a cleaning component, the cleaning component comprises a cleaning cavity, a piston, a dirt collecting chamber, a filter screen, a first check valve, a second check valve and a support, and the power component comprises a rotary disc, a connecting column and a connecting unit. The wind driven generator can be used for generating power by using stable wind power on the sea and can also be used for collecting and cleaning marine garbage by using power generated when a rotating component in the wind driven generator rotates.

However, the wind turbine generator is not suitable for practical use because it has a small carrying capacity and is likely to cause problems such as clogging when collecting garbage.
