Problems solved by technology

If the wave energy conversion mechanism is placed outside the inertial body, due to the large mass of the conversion mechanism itself, the inertial body can only have a small mass ratio, thereby reducing the wave energy capture efficiency

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The present invention provides an inertial wave energy powered buoy, comprising a buoy casing 21, a support frame 20 fixedly connected to the buoy casing, a fixed shaft 2 fixedly connected to the support frame, and an inertial pendulum integrated with a wave energy conversion mechanism. A groove is arranged at the bottom of the buoy housing 21, and the inertial pendulum is installed in the groove, and the shape of the groove is semicircular, and other shapes are also possible.

[0032] The inertial pendulum is installed on the fixed shaft 2 through ordinary bearings, and can swing relatively around the fixed shaft 2 inside the groove of the buoy shell. The inertial pendulum can rotate at any angle around the fixed axis 2 in the groove. The installation pos...

Abstract

The invention discloses an inertia wave energy power supply buoy. The inertia wave energy power supply buoy comprises a buoy shell and a power generation device and is characterized in that the powergeneration device is composed of an inertia pendulum located in the buoy shell, and the inertia pendulum swings in the buoy shell; the inertia pendulum comprises an energy capturing mechanism which converts back-and-forth swing of the inertia pendulum driven by waves into back-and-forth rotation to be output; a turning mechanism which is used for converting the back-and-forth rotation output by the primary energy capturing mechanism into single-direction rotation; and a power generator which is driven to generate electricity through the single-direction rotation output by the turning mechanism. Compared with the prior art, according to the inertia wave energy power supply buoy, a wave energy conversion mechanism is integrated in the inertia pendulum, the mass ratio of the inertia body relative to the buoy is increased, and therefore the energy capture efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of ocean wave energy power generation, and relates to an inertial wave energy power supply buoy. Background technique [0002] Monitoring marine hydrological and meteorological data is of great significance to the utilization and development of the ocean. At present, the main equipment for monitoring ocean data is buoys. Ocean buoys need to work at sea for a long time. If battery power is used, the battery is limited by its own capacity and needs to be replaced regularly, and it is extremely inconvenient to replace the buoy battery; using solar panels for power has problems such as low power generation and being limited by climate conditions. With the diversification of marine buoy functions, buoys need to carry more monitoring equipment, and higher requirements are placed on the power supply of buoys. Wave energy has a high energy density, and using wave energy to power buoys in situ can meet the high-capa...
