The application discloses a heat dissipation structure of an outdoor device and a centralized inverter integrated machine. The copper bar connected between an inverter and a transformer is connected with an internal cavity of an alternating current side of the inverter, heat generated by the copper bar is discharged to the inverter, and the heat exchanger in the inverter is used to discharge waste heat to the external environment. The heat dissipation problem of the copper bar connected between the inverter and the transformer and the connecting cavity is solved, and the cross-sectional size of the copper bar is reduced. The temperature of the copper bar connected between the inverter and the transformer and the connecting cavity is reduced, and the service life of internal devices is prolonged.

The application discloses a large-span light-weight self-balancing glass curtain wall and relates to the technical field of building curtain walls.The large-span light-weight self-balancing glass curtain wall comprises a curtain wall body, the curtain wall body comprises a steel truss and glass panels fixedly installed on the steel truss, exquisite steel support rods, a plurality of groups of the exquisite steel support rods are distributed in a vertical direction, each group of the exquisite steel support rods comprises two exquisite steel support rods symmetrically fixed on left and right sides of the steel truss, a circular hole is formed in an end of each exquisite steel support rod away from the steel truss, and an adjusting pull rod is arranged in the circular hole, and a plurality of stainless steel pull rods are symmetrically distributed on the two sides of the steel truss.The exquisite steel support rods and the stainless steel pull rods are symmetrically arranged, the conical tensioner and the adjusting pull rod are matched, a stable self-balancing tension system is formed, horizontal external forces, such as wind loads and earthquake actions, borne by the building during service can be effectively offset, and a significant out-of-plane bending moment of the glass panel can be avoided.

This invention discloses a lightweight modular FRP lifting device and its control method. The lifting device includes an expandable lifting frame body assembled from several basic structural units. Each basic structural unit adopts a steel-FRP composite structure, with an inner layer of I-beams and an outer layer of FRP fiber-reinforced fabric. A multi-degree-of-freedom adjustment mechanism is installed at the bottom of each basic structural unit. This mechanism includes a linear module and a winch. The linear module is set and fixed along the length of the basic structural unit, and the winch is fixed below the slider of the linear module. The winch's wire rope is connected to the lifting point of the building module to be lifted. The control method uses center-of-gravity calculation and a PID algorithm for real-time feedback control. This invention effectively solves the problems of heavy weight, difficult balance adjustment, and low level of intelligence in traditional lifting devices, achieving automatic leveling and precise positioning of the lifted building module, significantly improving lifting efficiency and safety.
