Description

Technical Field

[0001] The invention belongs to the technical field of power generation, and in particular relates to an ocean kinetic energy power generation device. Background Art

[0002] Ocean kinetic energy is a green, pollution-free, environmentally friendly renewable energy. The scientific development and utilization of ocean kinetic energy plays a positive role in alleviating the energy crisis and protecting the ecological environment of human society. Among them, the use of ocean kinetic energy to generate electricity can provide energy supply for underwater robots, submarines, underwater vehicles, etc., and effectively promote the development of underwater equipment technology. Large-scale ocean kinetic energy power generation can also provide electricity for islands, reefs and coastal facilities, effectively promoting the implementation of the country's "dual carbon" strategy.

[0003] The Chinese utility model patent "Wave Energy Power Generation Device and Its Use Method" (CN114704421A) discloses a wave energy gyro power generation device. The device frame includes an outer frame and an inner frame, the power generation shaft system module is placed on the inner frame, one end of the transmission module is connected to the side of the power generation shaft system module, and the other end is connected to the outer frame. Under the periodic excitation of waves, the device can convert wave energy into electrical energy, and has the characteristics of small size, easy installation and maintenance, and wide application range.

[0004] However, its outer frame is a ring structure with poor sealing performance. In the high humidity and high salt marine environment, this structure cannot prevent the outside air from bringing salt and water vapor into the generator. Therefore, the core components of the generator such as the gearbox, gyro rotor and generator are easily corroded. Summary of the invention

[0005] Purpose: To address the deficiencies in the prior art, the present invention provides an ocean kinetic energy power generation device.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a marine kinetic energy power generation device, including a generator, an electric motor, a gyro rotor module, an inner frame, and an outer frame. The gyro rotor module includes a gyro rotor, a main shaft, and a main shaft sleeve. The outer frame includes a sealing cover, a support plate, a support rod, and an end cover; the inner frame includes a layer plate, a side plate, and a hollow shaft. The gyro rotor is fixed on the main shaft. The main shaft sleeve is fixed on the layer plate. The rotating shaft of the motor is fixed to the gyro rotor, and the housing of the motor is fixed to the layer plate. The rotating shaft of the generator is fixed to the hollow shaft, and the housing of the generator is fixed to the support plate. When excited by waves or currents, the movement law of the device is as follows: the waves or currents cause the outer frame to roll, and under the drive of the motor, the gyro rotor rotates along the axis of the motor. Due to the gyro effect, the inner frame obtains an angular velocity along the axis of the generator, thereby driving the rotating shaft of the generator to rotate, so that the generator generates an induced electromotive force. Its structure is relatively simple, corrosion-resistant, and has low maintenance costs. The entire device can be directly fixed on above-water or underwater equipment and provide energy supply for these equipment.

[0007] Preferably, the outer frame is composed of a sealing cover, a support plate, a support rod, and an end cover.

[0008] Preferably, the sealing cover is a transparent hollow cylindrical shell.

[0009] Preferably, the support rod is a variable cross-section rod with threads at both ends. The end caps are placed at both ends of the support rod and fixed by nuts, and the support plate is placed at the step of the support rod and positioned by the step of the support rod.

[0010] Preferably, a groove is provided on one side of the end cover, and the sealing cover is installed in the groove of the end cover.

[0011] Preferably, the inner frame is composed of a concave layer plate, a rectangular side plate and a hollow shaft. The upper plate and the side plate are fixed by bolts, and the hollow shaft is fixed to the side plate by bolts.

[0012] Preferably, the rotating shaft of the generator and the torsion spring shaft on which the torsion spring is placed are on the same axis.

[0013] Beneficial effect: The present invention provides an ocean kinetic energy power generation device that can convert ocean kinetic energy into mechanical energy. The device has a simple structure, is easy to miniaturize, is corrosion-resistant, has high device reliability and low maintenance cost, and can power underwater or submerged equipment.
