The utility model relates to a novel photovoltaic support structure, which belongs to the field of photovoltaic technology and comprises a support structure formed by mutually connecting a main beam, a connecting beam, a purline and a support column, an enclosure structure is arranged on the support structure, and a light reflecting device and a sensing control device are arranged in the support structure. The enclosure structure comprises a double-glass assembly, a thin film and a film rolling device, the double-glass assembly is fixed to the upper end of the supporting structure, and the thin film is arranged on the outer side of the supporting structure and can be rolled and unrolled through the film rolling device; the film rolling device is located below the double-glass assembly and can reflect sunlight entering the supporting structure to a back plate of the double-glass assembly, and the sensing control device is connected with the film rolling device and the light reflecting device and can control the film rolling device and the light reflecting device to work. And the novel photovoltaic support structure can actively improve the light incoming amount gain power generation of the back plate of the double-glass assembly through the light reflecting device.

The application provides a kind of generation method and system for the stereoscopic printing data of scanning feature parts, the method comprises: obtaining a plurality of scanning track points of a part to be printed;Obtain a plurality of cross-sectional profile points of the part to be printed at each scanning track point, and record as cross-sectional profile point data;Coordinate conversion is carried out on the cross-sectional profile point data to generate tangent plane profile point data;According to the distance between the tangent planes corresponding to adjacent scanning track points, generate tangent plane distance data;According to the tangent plane profile point data, generate printing trajectory data;According to the tangent plane distance data and the preset line width data, generate printing speed data;And according to the printing trajectory data and the printing speed data, generate the stereoscopic printing data of the part to be printed.The application can realize support-free adaptive spatial slicing, save support materials, and improve printing accuracy.

The utility model discloses an improved prefabricated T-beam temporary supporting device which comprises an adjustable lifting rod, one end of the adjustable lifting rod is detachably connected with a supporting mechanism, and the other end of the adjustable lifting rod is detachably arranged in a fixing mechanism in a penetrating and sleeved mode. The supporting mechanism comprises a supporting top plate; the lower end of the supporting top plate is connected with a supporting sleeve which is connected with the upper end of an adjustable lifting rod in a pluggable mode. The upper end of the fixing mechanism is in lifting movable fit with the adjustable lifting rod, and the lower end of the fixing mechanism makes contact with or is connected with the ground. And the adjustable operating part is arranged on the adjustable lifting rod in a penetrating and sleeving manner in a sliding manner and is used for manually completing lifting of the adjustable lifting rod in the fixing mechanism. The height adjusting device is compact in structure, rapid and convenient to adjust in height, small in occupied space and capable of being rapidly and easily installed on a T-shaped beam or a cross beam needing to be supported in a limited space, time and labor cost are saved, it is guaranteed that the T-shaped beam or the cross beam keeps stable in structure under the action of bearing gravity or other external force, and deformation or inclination is avoided.
