Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] as attached figure 1 As shown, the present invention provides an underwater inflatable flexible solar concentrator and a photovoltaic power generation system thereof. The system includes an inflatable flexible solar concentrator, a solar cell group, a lifting rope and a control platform, wherein the inflatable flexible solar concentrator is composed of a communication pipe, a valve, a flexible transparent film, a bracket and a gas medium inside it. Sunlight shines on the sea surface, and the light passes through the seawater to reach the light-incident surface of the flexible concentrator. Due to the difference in refractive index between the internal gas medium and seawater, the light is refracted and converged when passing through the concentrator, and is transmitted by the solar cell located on its focal plane. The group receives and converts li...

Abstract

The invention provides an underwater inflatable flexible solar concentrator applied to an underwater working device and a photovoltaic power generation system thereof and belongs to the technical field of new energy application. At a non-working state, the underwater inflatable flexible solar concentrator is accommodated in an accommodation box at the top end of the underwater operation device. The underwater inflatable flexible solar concentrator is composed of an inflatable flexible solar concentrator body, a solar cell array, a control platform, a lifting rope and the like. During work, the underwater inflatable flexible solar concentrator inflates the concentrator body and pulls the concentrator body to a specific position of underwater operation by adjusting the lifting rope to enable the solar cell array to be located on the focal plane of the concentrator body. Parallel light is refracted in water through the concentrator body and converged on the solar cell array to convert light energy into electric energy. The electric energy is stored in the control platform through a storage battery, and the using electric power needed by the underwater operation device is obtained after the electric energy passes through an inverter. Charging and discharging of the storage battery, energy supply of the underwater operation device and winding and unwinding of the lifting rope are all achieved through control of the control platform.

Description

[0001] Technical field [0002] The invention relates to an underwater inflatable flexible solar concentrator and a photovoltaic power generation system thereof. The underwater inflatable flexible solar concentrator and its photovoltaic power generation system are located underwater, use the principle of geometric optics to concentrate light and convert light energy into electrical energy through photovoltaic panels, and provide energy supplies for underwater operating devices The system belongs to the field of new energy application technology. Background technique [0003] The ocean is the cradle of life, accounting for about two-thirds of the earth's surface area, not only contains a large number of resources, but also has a significant impact on the global climate and environment. In recent years, with the deepening of marine research, people have gradually deepened their underwater exploration, and the number of underwater working devices has increased. Therefore, the en...
