[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example: Reference Figure 1-4 A heat-insulating structure for a roof of a civil building is shown, comprising a base plate 1, a reserved groove 2 is provided in the middle of the base plate 1, a dual-shaft motor 3 is provided inside the reserved groove 2, a transmission rod 4 is fixed to both output shaft ends of the dual-shaft motor 3, a first bevel gear 5 is fixed to the other end of the transmission rod 4, the two first bevel gears 5 are respectively arranged on the left and right sides of the base plate 1, a support frame 6 is fixed to the left and right sides of the base plate 1, and a plurality of mounting holes 14 are provided on the base plate 1, with the help of the plurality of mounting holes 14, the base plate 1 is easier to be installed on the roof for use, the top of the inner side of the support frame 6 is rotatably connected to the first screw rod 7 through a bearing, and the bottom end of the first screw rod 7 is fixed to the second conical gear 5. Gear 8, the first bevel gear 5 and the second bevel gear 8 located on the same side of the base plate 1 are meshed with each other, a carrier block 9 is threadedly connected to the first screw rod 7, a carrier frame 10 is fixed between the two carrier blocks 9, a plurality of thermal insulation components arranged linearly from left to right are provided inside the carrier frame 10, a rotating rod 11 is fixed on the front and rear sides of the thermal insulation component, the rotating rod 11 and the carrier frame 10 are rotatably connected through a bearing, a cylindrical gear 12 is fixedly sleeved on the outside of the front rotating rod 11, a fixing plate 13 is fixed on the front side of the carrier frame 10, a driving assembly is provided on the fixing plate 13, the driving assembly is used to drive the cylindrical gear 12 to flip, and the thermal insulation assembly is used for thermal insulation protection of the roof;

[0022] The driving assembly can be used to pull multiple cylindrical gears 12 to rotate, so that the multiple cylindrical gears 12 drive multiple insulation assemblies to flip. In this way, the sun-facing side of the insulation assembly can be adjusted accordingly according to seasonal changes, so that the insulation needs of the building roof in winter and summer can be met. The dual-axis motor 3 is used to drive the two transmission rods 4 to rotate simultaneously, so that the two transmission rods 4 pull the two first bevel gears 5 to rotate. With the help of the first bevel gear 5 and the second bevel gear 8 engaging with each other, the first screw rod 7 can be pulled to rotate, so that the two first screw rods 7 can adjust the distance between the support frame 10 and the base plate 1 in a screw drive manner. In this way, the insulation assembly after the sun-facing side is adjusted can be re-attached to the base plate 1 to better help insulate the roof.

[0023] Among them, a plurality of partitions 15 arranged linearly from left to right are fixed on the upper surface of the bottom plate 1. The plurality of partitions 15 are spaced apart from the plurality of thermal insulation components. A guide block 16 is fixed on the top of the partition 15.

[0024] Filling the gap between two adjacent insulation components with the help of the partition 15 can not only improve the stability of the position of the two adjacent insulation components, but also help insulate the roof. The use of the guide block 16 makes it easier to insert the partition 15 between the two adjacent insulation components.

[0025] The heat insulation assembly includes a protective frame 17, on which the rotating rod 11 is fixedly mounted. A heat insulation layer 18 is fixed inside the protective frame 17. A reflective plate 19 and a heat absorption layer 20 are fixed on the upper and lower sides of the heat insulation layer 18, respectively. The heat absorption layer 20 is made of black rubber material.

[0026] During the high temperatures in summer, the reflective plate 19 reflects sunlight and causes the roof to heat up more slowly. In winter, the heat-absorbing layer 20 can better help the roof heat up with the help of sunlight. At the same time, the thermal insulation layer 18 can play a heat-insulating role. In this way, the indoor temperature is less affected by the roof, which is more conducive to the insulation and heat preservation inside the building.

[0027] The driving assembly includes a rectangular frame plate 21, which is fixedly mounted on the fixed plate 13. A second screw rod 22 is rotatably connected between the left and right inner walls of the rectangular frame plate 21 through a bearing. A slider 23 is threadedly connected to the second screw rod 22. The slider 23 slides with the inner wall of the rectangular frame plate 21, and a rack 24 is fixed to the bottom of the slider 23. The rack 24 and the multiple cylindrical gears 12 are all meshed with each other. A single-axis motor 25 is provided on the right side of the rectangular frame plate 21, and the second screw rod 22 is driven by the single-axis motor 25.

[0028] The single-axis motor 25 is used to drive the second screw rod 22 to rotate, and the second screw rod 22 pulls the slider 23 in a screw transmission manner to drive the rack 24 to move. With the help of the rack 24 and the multiple cylindrical gears 12 engaging with each other, the multiple cylindrical gears 12 can be driven to rotate synchronously, thereby completing the synchronous adjustment of the sun-facing sides of multiple insulation components.

[0029] Working principle of this utility model:

[0030] The base plate 1 is laid on the roof of a civil building and fixed to the roof with bolts along the mounting holes 14. In the hot summer, when there is sufficient sunlight, the reflector 19 in the heat insulation assembly is on the sun-facing side, which can effectively reflect sunlight, reduce the temperature of the base plate 1 and the heat insulation assembly itself, and slow down the temperature rise of the roof. The heat insulation layer 18 can also play a heat insulation role, thus reducing the impact of the high temperature of the roof on the indoor room, so that the indoor room remains cool.

[0031] In the cold winter, the dual-axis motor 3 can be controlled to drive the two transmission rods 4 to rotate forward, and the transmission rod 4 pulls the first bevel gear 5 to rotate. With the help of the first bevel gear 5 and the second bevel gear 8 meshing with each other, the first screw rod 7 can be pulled to rotate. The first screw rod 7 pulls the carrier block 9 to move in the form of a screw drive, so that the two carrier blocks 9 can drive the carrier frame 10 to move up until the partition 15 is completely separated from the heat insulation component. The single-axis motor 25 is controlled to drive the second screw rod 22 to rotate. The second screw rod 22 pulls the slider 23 to drive the rack 24 to move in the form of a screw drive. With the help of the rack 24 and a plurality of cylindrical gears The wheels 12 are meshed with each other, which can drive multiple cylindrical gears 12 to rotate synchronously, completing the synchronous adjustment of the sunny sides of multiple insulation components. At this time, the heat absorption layer 20 is on the sunny side, which can better absorb the heat brought by the sunlight and provide insulation for the roof. After the insulation component is turned over, the dual-axis motor 3 can be controlled to drive the two transmission rods 4 to rotate in the opposite direction, driving the supporting frame 10 to move downward, so that the supporting frame 10 is again fitted with the bottom plate 1. At this time, the partition 15 blocks the gap between the two adjacent insulation components, and the insulation layer 18 can prevent the indoor heat from being lost along the roof to a certain extent, so that the indoor temperature is warmer.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
