2results about How to "Improve self-sufficiency" patented technology

The application discloses an offshore photovoltaic power generation protection system based on air curtain wave abatement, and relates to the technical field of photovoltaic power generation protection devices. The system not only provides reliable protection for offshore photovoltaic power generation energy storage devices, but also reduces the dependence on external energy and improves the energy self-sufficiency rate of the whole system. The system comprises a photovoltaic power generation energy storage device and a plurality of air curtain wave abatement devices arranged on the periphery of the photovoltaic power generation energy storage device. The photovoltaic power generation energy storage device comprises photovoltaic panels arranged on a mounting structure and solar cells electrically connected with the photovoltaic panels. The air curtain wave abatement device comprises an air compressor and an exhaust pipe. The air compressor is arranged on the mounting structure and located outside the photovoltaic power generation energy storage device. The exhaust pipe is laid in the underwater area outside the solar cells and has an inlet end in communication with the air compressor. A plurality of exhaust holes and counterweights are arranged on the exhaust pipe. The air compressor is electrically connected with the solar cells. The application is used for improving the performance of the photovoltaic power generation protection system.

The application discloses an Internet of Things data collection box, and belongs to the field of data collection equipment. The collection box comprises a collection box main body, a solar cell panel is installed on the top of the collection box main body through a support, and a cleaning mechanism for cleaning dust on the surface of the solar cell panel is arranged on the support; a water spraying mechanism is arranged on the support, the water spraying mechanism comprises a water pipe installed on the cleaning mechanism, a plurality of spray heads fixedly arranged along the length direction of the water pipe at equal intervals, a water tank arranged on the inner side of the support, a water pump installed on the water tank and communicated with the water tank, and a hose fixedly installed on the output end of the water pump and communicated with the water pipe. When the cleaning mechanism operates, water flow can be sprayed onto the surface of the solar cell panel synchronously, so that dust and sundries can be scraped off by the scraper in a wet state. Compared with the traditional dry scraping mode, the design greatly improves the cleaning efficiency, reduces the cleaning blind area, and avoids the influence of dust residues on the power generation efficiency of the solar cell panel.
