This utility model discloses a greenhouse based on a single-layer front slope and double-layer gable wall, belonging to the technical field of greenhouses. This utility model aims to solve the problems of long construction cycles and high costs associated with the insulation layers of traditional greenhouse back walls and gable walls. The utility model includes multiple outer greenhouse frames, horizontal frames, a central column, greenhouse film, and a front slope insulation blanket. The multiple outer greenhouse frames are linearly distributed and installed on the greenhouse foundation. The horizontal frames are installed on the outer greenhouse frames, connecting them together. The central column is installed on the inner wall of the outer greenhouse frames. A greenhouse film is installed on the front slope of each outer greenhouse frame, and a retractable front slope insulation blanket is installed on the front slope of the outer greenhouse frame. Using a double-layer insulation blanket as the insulation material simplifies the construction process and reduces costs. Simultaneously, the double-layer insulation blanket structure and the cavity formed between them ensure effective heat insulation.

The embodiment of the application discloses a kind of wisdom morphing aircraft and morphing control method, including cabin body base and the skin structure covered in the outer surface of the cabin body base;The cabin body base includes first cabin body base and second cabin body base, and the second cabin body base is combined and fixed to the first cabin body base away from the vertex of the aircraft one end;Multiple first driving members are included between the skin structure and first cabin body base, and the first driving member is configured to drive the skin mechanism to change the shape of the wisdom morphing aircraft;Multiple second driving members are included between the skin structure and the second cabin body base, and the second driving member is configured to drive the skin structure to change the shape of the wisdom morphing aircraft.By corresponding setting skin structure in different cabin section of aircraft, the segmented regulation and control of the shape of aircraft body is realized, and the aerodynamic shape of aircraft is optimized, so that it can adapt to the flight requirements of different flight tasks.

The application discloses a prefabricated ice building indoor ceiling structure, belongs to the technical field of ice building construction, and aims to solve the problem of poor heat preservation effect of the existing indoor roof heat preservation measures for the indoor ceiling structure of an ice building. The indoor ceiling structure comprises a heat insulation plate, a cast ice plate and N connecting nails, wherein N is a positive integer, the cast ice plate is arranged on the top of the heat insulation plate, the cast ice plate is fastened to the heat insulation plate through the N connecting nails, the connecting nail comprises a limiting plate, a vertical nail body and a traction line, the vertical nail body is fixedly connected to the top center of the limiting plate, the axis of the vertical nail body is arranged in line with the axis of the limiting plate, the limiting plate is arranged below the heat insulation plate, the vertical nail body penetrates through the heat insulation plate and is correspondingly arranged in an ice surface through hole, the vertical nail body is fixedly connected to the cast ice plate through ice end water filling, and one end of the traction line is fixedly connected to the top end of the vertical nail body. The application is mainly used as an indoor ceiling structure in an ice building.

The utility model discloses a heat preservation and insulation type door and window which comprises a window frame, the top end and the bottom end of the window frame are respectively provided with an installation clamping groove, two windows which are rotationally symmetrical in position are installed on the inner side of the window frame in a sliding mode, and the top end and the bottom end of each window are connected to the inner sides of the two installation clamping grooves in a sliding and clamping mode respectively. A plurality of supporting springs are fixed to the inner side of the mounting clamping groove, a supporting strip is fixed to one end of each supporting spring, the supporting strips are attached to the window, sealing strips are embedded in the two sides of each supporting strip, a sealing plate is fixed to the upper surface of one end of each supporting strip, and a guide face is arranged at the end, close to the window, of each sealing plate. The supporting strip and the sealing plate are additionally arranged between the window and the window frame, it is guaranteed that the supporting strip is attached to the window all the time through the supporting spring, meanwhile, the gap between the supporting strip and the window frame is filled with the sealing strip, indoor air and outdoor air are isolated, and therefore the heat preservation and heat insulation performance of the door and window is guaranteed.
