The invention discloses a double-locking full-time protection safety device which comprises an outer shell, a safety sleeve body, rotating shaft pins, fixing rods, locking pin rings and a safety belt sleeve. The safety sleeve body comprises an upper plate face and a lower plate face which are integrally formed, and a pair of locking pin openings is formed in the connection face of the upper plate face and the lower plate face; a sliding block groove is formed in the upper plate face, and two locating grooves are formed in the lower plate face. A swing arm movably connected with the rotating shaft pins is arranged at the upper end of the upper plate face, and a support is movably connected to the swing arm and fixedly connected with the upper plate face through threaded holes; the safety sleeve body is provided with a pair of locking sheets connected through a spring. By means of the double-locking full-time protection safety device, the technical problem of potential safety hazards can happen during high-altitude moving operation through an existing safety belt is solved, and the double-locking full-time protection safety device has the advantages of being convenient to carry, safe and reliable.

The invention relates to an intelligent curtain wall cleaning system. The system comprises a controller, moving rails of upper and lower frames of a curtain wall and box-shaped vertical columns on theleft and right sides of the curtain wall, and the vertical columns are internally provided with columnar roller brushes; the upper and lower ends of the columnar roller brushes are respectively arranged in the moving rails of the upper and lower frames of the curtain wall, and can rotationally move along the moving rails to clean the curtain wall; a raindrop sensing device is arranged at the upper portion of one of the vertical columns, and the controller controls the columnar roller brushes to clean the curtain wall based on a detection result of the raindrop sensing device. The system achieves the intelligent self-cleaning of the curtain wall.

The invention relates to an easily-handled inward tilt-turn door / window hinge assembly with a bearing reinforcing structure. The easily-handled inward tilt-turn door / window hinge assembly comprises a window frame connection structure and a window / door connection structure. The window frame connection structure is connected with the window / door connection structure through a hinge structure so that an extensible sliding door / window structure is formed. The easily-handled inward tilt-turn door / window hinge assembly is characterized in that the window frame connection structure comprises a window frame hinging plate, at least two rigid fasteners and at least two moving connectors; the rigid fasteners and the moving connectors are disposed on the window frame hinging plate; the rigid fasteners are arranged on the inner side of the window frame hinging plate; the moving connectors are arranged on the outer side of the window frame hinging plate; the rigid fasteners directly extending out of the bottom of the window frame hinging plate are integrated to the window frame hinging plate or are fixedly connected to the bottom of the window frame hinging plate; the moving connectors rotatably disposed at the bottom of the window frame hinging plate are internal-adjustment rotating members, and a moving adjusting connection structure of a window frame is formed by rotational adjustment of the moving connectors. The easily-handled inward tilt-turn door / window hinge assembly has the advantages such that bearing capacity is high, the window / door and the window frame can be stably connected, deformation or loosening rarely occurs, and safety is high.
