The utility model relates to a kind of solar photovoltaic panel rain-sheltering support of turnable, photovoltaic panel is fixed on board seat, and the board seat is fixed with side plate, and side plate is hingedly connected with straight connecting rod and curved connecting rod, the other end of the straight connecting rod and curved connecting rod is hingedly connected on upper layer base, and the straight connecting rod and curved connecting rod are cross distribution with front and back interval, and the two ends of curved connecting rod are elbow type, and the elbow type two ends of curved connecting rod are central symmetry with curved connecting rod middle part;Any connecting rod is connected with the driving assembly of driving rotation at hinging point place.The utility model provides a kind of photovoltaic panel turnover support by driving motor driving, by connecting rod, so that photovoltaic panel can be turned over 180 °, and by front face upside down to front face downward, so that rainwater cannot be sprinkled to photovoltaic panel front face, to reduce the dirt condition formed by rainwater mixed dust dry, and then subsequent photovoltaic panel cleaning frequency can be reduced, and cleaning cost expenditure is reduced.

This invention discloses a production process for interweaving wool-type composite yarn with silk. The steps are as follows: the tension of both wool and iterated polyester yarn-D is 1g, the twisting tension is 15±0.5g, the twist is 5T, and after setting and forming into bobbins, wool-type composite yarn is obtained; the warp A, warp B and C of the warp and weft interweaving are all raw silk, the weft A is 40N / 1 wool, and the weft B is wool-type composite yarn; the interwoven fabric is immersed in a scouring tank and the sericin of the raw silk warp is removed intermittently, the scouring tank is filled with silk and wool liquid protease; disperse dye and wool reactive dye are placed in the same dyeing vat, dyeing is first carried out at room temperature, and then the temperature is raised, kept warm and lowered in sequence, and the residual water after dyeing is discharged after cooling; during alkaline washing, the temperature is raised, kept warm and lowered, and the residual water after washing is discharged after cooling; the dyed fabric is immersed, squeezed and then hot air stretched and dried, and then low temperature set in eight boxes. Using the above technical solution, the composite yarn has high quality, the fabric is dyed evenly with less staining, and the iterative polyester yarn-D has good color fastness and excellent wearability.
