This application discloses a corner-claw photovoltaic glass and its right-angle glass claw, belonging to the technical field of vertical suspension installation of double-sided photovoltaic power generation glass, and is suitable for sway-resistant wind power generation systems. The corner-claw photovoltaic glass includes double-sided photovoltaic power generation glass, with right-angle glass claws attached to its corners. The right-angle glass claw is divided into a right-angle edge bonding area and a right-angle outer edge mounting area. The bonding area is adhered to the mutually perpendicular edge areas of the glass corner by an adhesive layer, and the mounting area is provided with mounting holes for connection to movable connectors. The right-angle glass claw is preferably tempered glass, which can form a U-shaped structure to achieve force distribution on both the front and back sides of the glass. This application replaces existing hanging clamps, solving the defects of existing solutions such as high cost, easy generation of hot spots, and poor stability. It has the advantages of low cost, no shading, strong wind resistance, convenient installation, and long service life, enabling low-cost, high-stability vertical suspension installation of double-sided photovoltaic power generation glass without elastic pads.

The utility model relates to wind driven generator technical field discloses a vertical axis wind driven generator, including fan main shaft, a plurality of first blades, a plurality of first blades are along the circumferential interval of fan main shaft set up on fan main shaft, and a plurality of first blades form first blade group, a plurality of second blades, a plurality of second blades are along vertical direction set up on the downside of first blade group fan main shaft, and a plurality of second blades form second blade group, and second blade group at least partial with generator is at same horizontal height, the vertical axis wind driven generator of the utility model, through setting second blade group downside first blade group, and second blade group at least partial with generator is at same horizontal height, can reduce the gravity position of wind wheel whole. The structure setting of double -deck blade group can alleviate the tremble in the rotation of wind wheel, reduce the possibility of resonance occurrence, are favorable to keep the stable of power generation efficiency.

This application discloses a photovoltaic module and its frame structure. By installing a scraper that can expand and contract with temperature on the lower surface of the top plate of the frame, the scraper can bulge or be flush with the inner side of the top plate when it expands with temperature. Therefore, the dust accumulated between the laminate and the frame can be squeezed inward by the thermal expansion and contraction of the scraper. During rainfall, the dust is washed away by rainwater, and then discharged through the through-holes set on the top plate by the siphon effect, thus achieving a self-cleaning function. This increases the cleanliness of the laminate surface and ensures power generation efficiency. This can extend the cycle of manual dust cleaning. Moreover, the frame structure is intact, and there is no need to remove the top plate or redesign the pressure block, which reduces costs and ensures mechanical strength.

This invention discloses a desert edge photovoltaic ecological barrier system in the field of desertification control. From the desert side to the oasis side, it comprises: a dune-blocking belt, located on the ridge line of the dune chain, with adjustable tilt angle and height; a grid-like blocking belt, using a woven mesh structure to three-dimensionally intercept and stabilize large-scale shifting sand; a low-lying vertical sand-fixing belt, also using a woven mesh structure to stabilize near-surface windblown sand and fix loose sand particles; a first sand-blocking forest belt; a photovoltaic zone; a second sand-blocking forest belt; and a restoration zone. The beneficial effects of this invention are: by systematically integrating multiple levels of structures such as sand source blocking, grid-like sand fixation, windbreak forest belts, extensive array sand control, and enclosure and restoration, a continuous ecological protection chain is constructed from the desert side to the oasis side, effectively improving the system's sand-fixing capacity, ensuring the operational stability and power generation efficiency of the photovoltaic power station, and improving the ecological environment of the desert edge.
