This utility model relates to the field of noise control technology, and in particular to a transformer noise isolation device, comprising a housing, the housing being a square frame adapted to a transformer, an opening on the front side of the housing for inserting the transformer, and an internal cavity for storing the transformer inside the housing; it also includes a hinge, a soundproof door panel, and a locking assembly, etc. A soundproof door panel is hinged to one side of the front opening of the housing, and an inner groove adapted to the soundproof door panel is provided at the edge of the front opening of the housing. A locking assembly for locking the soundproof door panel is provided on the housing. This utility model, through the sound insulation layer inside the housing, the high-density multi-layer structure of the soundproof door panel, and the application of a rubber sheet, combined with a fastening component, ensures that the rubber sheet is pressed tightly when the soundproof door panel is closed, thereby minimizing noise leakage from the gap between the door panel and the housing, achieving the effect of isolating transformer noise within the housing.

The utility model discloses a kind of angle-adjustable and wind-resistant damping flexible photovoltaic support, including photovoltaic board, support, steel strand and damping mechanism;The steel strand is connected with support, forms well-shaped support frame;The photovoltaic board is installed at the top of well-shaped support frame;The damping mechanism includes damping assembly, connecting assembly and angle adjusting assembly;The top of damping assembly is fixedly connected in the middle of steel strand, bottom and connecting assembly are rotatablely hinged together;The angle adjusting assembly includes fixed part, and fixedly installed with the regulator matched with connecting assembly on fixed part.The utility model damping mechanism and angle adjusting assembly cooperate, solve the problem that existing flexible photovoltaic support cannot adjust angle and wind-resistant damping performance is weak;Photovoltaic board can be adjusted according to the position change of sun Angle, to optimize light energy absorption efficiency, simultaneously, by the connection of damping assembly and steel strand, vibration caused by external factor is effectively dispersed and reduced, and the stability of entire system is improved.
