The utility model provides a kind of adjustable photovoltaic sun shield, it includes: fixed on the corner embedded part of building balcony civil engineering beam, with the corner embedded part fixed electric control pivot, fixed on the electric control pivot photovoltaic module, set on the illumination monitoring device and control device of building outer wall, the control device with the illumination monitoring device and the electric control pivot are connected, for according to the solar elevation angle of the illumination monitoring device to control the rotation angle of the electric control pivot.The utility model has the advantages of energy saving and easy maintenance.

The application provides a buoy-shaped double-layer structure wave energy friction nanogenerator, which comprises a buoy shell, an inner layer power generation unit arranged in the buoy shell and an outer layer power generation unit arranged between the inner layer power generation unit and the buoy shell, the inner layer power generation unit is a sliding friction type power generation device and utilizes heaving wave energy to generate electricity, and the outer layer power generation unit is a squeezing friction type power generation device and utilizes pitching wave energy to generate electricity.The application can collect omnibearing wideband wave energy with maximum efficiency through resonance effect and convert the wave energy into electric energy.

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.
