The parent-child oscillating water column power generation device simultaneously lowers the first-level oscillating water column, the second-level oscillating water column, and the third-level oscillating water column into the water to form a nested air cavity, which enhances the exchange of airflow and thus improves the power generation efficiency of the oscillating water column.

The upper power generation device retracts the vertical axis fan to avoid damage. Under the action of wave height, the oscillation amplitude of the counter-rotating oscillating float power generation device is enhanced, the efficiency of oscillating compressed air power generation is improved, and damping in the heave direction is generated, thereby increasing the stability and accuracy of the device in observation under high sea conditions.

[0017] Beneficial effects: The target observation device of the present invention can adaptively change the internal chamber structure of the oscillating water column according to the sea conditions and weather conditions of the observed target, maximize the wave energy conversion to extend the working time of the overall system of the observation device, and improve the observation stability and accuracy of the overall device based on the heave damping generated by the bottom counter-rotating float power generation device, further protect the upper wind photovoltaic combined power generation device, thereby reducing the maintenance and operation costs of the observation device, and at the same time promote the wider application and development of renewable energy in the marine field.
