A blade automatic opening and closing type ocean current power generation device

Abstract

The invention provides a blade automatic opening and closing type marine current energy power generating set. The marine current energy power generating set comprises a blade mechanism, a central rotating body and a support base in which a cabin is arranged, wherein the blade mechanism comprises blade mounting shafts fixedly connected to the central rotating body, the mounting shafts are of a hollow cylindrical structure, and two pieces of blades capable of opening and closing are separately arranged on each mounting shaft; the outermost ends of the mounting shafts are provided with limiting components for limiting the blades to axially slide; sliding rods for controlling the opening and closing of the blades are arranged in the mounting shafts, one ends of the sliding rods control the opening and closing of the blades through opening and closing mechanisms, and the other ends of the sliding rods are connected with a crank connecting rod of the central rotating body; the central rotating body is provided with two pairs of meshing gears and a crank connecting rod mechanism; the central rotating body comprises a rotating shaft fixedly connected with the central rotating body, and the rotating shaft is coaxially connected with a motor in the support base; and the support base is provided with a mounting position for fixedly connecting an internal meshing gear wheels and a groove matched with the central rotating body, and the bottom end of the support base is fixedly connected with a base. In the rotating process, the blades can make periodical opening and closing motion and continuously provide power for the motor.

Description

technical field [0001] The invention relates to an ocean current energy utilization device, in particular to an ocean current energy generating device with blades automatically opening and closing, which is suitable for ocean current energy utilization, ocean power generation and other power devices. Background technique [0002] With the increasingly severe energy problems, people pay more and more attention to the development and utilization of new energy and renewable energy. People gradually realize that there are huge energy sources in the ocean, such as temperature difference energy, salinity difference energy, wave energy, ocean current energy, tidal energy, etc. The turbulent waters have a lot of kinetic energy during high tide and low tide. At the same time, in special areas such as some islands, there will be stable ocean currents due to factors such as submarine topography. After continuous research and development, there are various forms of ocean current energ...

Problems solved by technology

It is difficult for the traditional blade opening and closing type power generation device to realize the automatic opening and closing of the blades. For example, the "blade automatic opening and closing type sea current energy generation device" provided by the Chinese Patent Publication No. CN 202645835 U, the blades can be realized by the force of the string at a certain moment. Opening and closing, thereby changing the moment of the opposing blades, but its disadvantage is that the life of the string is low and it is very sensitive to disturbances. Once the direction of the sea current changes slightly, it is difficult to realize the periodic opening and closing process.

The current ocean current power generation devices have disadvantages such as difficult installation, low power generation efficiency, high cost, and strict requirements on the use of environmental conditions. The use of energy is of great significance
