DETAILED DESCRIPTION

[0022] In order to achieve the above-mentioned purpose and effect, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0023] like Figure 1-Figure 7 As shown, the present invention provides a rotatable and fitted building curtain wall structure, including a plurality of composite panel components 1, wherein the composite panel components 1 include a heat insulation layer 11, a heat storage layer 12 and a heat absorption layer 13 arranged in sequence; the cross section of the composite panel component 1 is a parallelogram, and a support shaft 14 is arranged in the middle of the composite panel component 1; it also includes two support columns 3 fixed to the outer surface of the building 4, and a rotating component 2 is arranged on both sides of each composite panel component 1, and the composite panel component 1 is connected to the two support columns 3 respectively through the rotating components 2 on both sides; the rotating component 2 includes a mounting plate 21 and two connecting rods 2 arranged in parallel. 2; the mounting plate 21 is arranged parallel to the support column 3, one end of the connecting rod 22 is rotatably connected to the mounting plate 21, and the other end is rotatably connected to the support column 3; the mounting plate 21 is provided with a mounting groove 211, a vertically arranged sliding hole 212 is provided in the mounting groove 211, the support shaft 14 is slidably arranged in the sliding hole 212, a flywheel mechanism 214 is installed on the support shaft 14, and a first rack 213 cooperating with the flywheel mechanism 214 is fixedly installed in the mounting groove 211; the support column 3 is a hollow structure, and a driving mechanism for driving the connecting rod 22 to rotate is arranged inside the support column 3. The flywheel mechanism 214 includes a first gear 2141, a bearing 2143 and a ratchet 2144; the first gear 2141 is installed on the support shaft 14 through the bearing 2143, the ratchet 2144 is installed on the support shaft 14, and one end of the first gear 2141 is provided with an inner ratchet structure 2142.

[0024] In this embodiment, when the external climate changes significantly, the driving mechanism drives the connecting rod 22 of the rotating assembly 2 to rotate upward by a certain angle, so that the mounting plate 21 is away from the outer surface of the building 4, leaving space for the composite panel assembly 1 to rotate; under the action of its own gravity, the composite panel assembly 1 drives the support shaft 14 to slide downward along the sliding hole 212, and the first gear 2141 rotates downward along the first rack 213. Under the limiting action of the ratchet 2144, the inner ratchet structure 2142 drives the support shaft 14 to rotate, so that the composite panel assembly 1 rotates 180°, and the heat insulation layer 11 and the absorption layer 11 are aligned. The hot layer 13 swaps positions; after the composite panel assembly 1 completes the rotation, the driving mechanism drives the connecting rod 22 of the rotating assembly 2 to rotate downward and reset. The composite panel assembly 1 at the bottom layer is guided by the pad 7 with a triangular cross section at the bottom of the building 4, so that the composite panel assembly 1 rises until it fits with the outer surface of the building 4. During the movement, the composite panel assembly 1 drives the support shaft 14 to slide upward along the sliding hole 212, and the first gear 2141 rotates upward along the first rack 213. Since the ratchet 2144 cannot be limited, the internal ratchet structure 2142 no longer drives the support shaft 14 to rotate. The composite panel assemblies 1 of other layers are guided by the top inclined surface of the composite panel assembly 1 of the next layer to rise. The composite panel assembly 1 adopts a parallelogram structure, which is convenient for movement guidance on the one hand, and can make the composite panel assemblies 1 fit tightly with no gaps on the other hand.

[0025] In another embodiment, if Figure 4 As shown, a second rack 216 meshing with the first gear 2141 is slidably disposed in the mounting groove 211 , and the second rack 216 is disposed opposite to the first rack 213 to improve the movement stability of the first gear 2141 .

[0026] In another embodiment, if Figure 4 , Figure 5As shown, a viscous damper 215 and a limiting column 217 are also provided in the mounting groove 211. The viscous damper 215 is located below the second rack 216. A spring 218 is provided at the end of the limiting column 217. The spring 218 is used to clamp the limiting column 217 on the second rack 216. An elastic protrusion 2171 is provided on the limiting column 217, and an inclined surface is provided on the elastic protrusion 2171. A first rotating shaft 221 is provided at one end of the connecting rod 22 of the rotating assembly 2 connected to the mounting plate 21, and a lever 2211 cooperating with the elastic protrusion 2171 is provided on the first rotating shaft 221. When the connecting rod 22 rotates upward, the first rotating shaft 221 rotates relative to the mounting plate 21, so that the lever 2211 pushes the elastic protrusion 2171 in the direction of the spring 218, driving the limiting column 217 to move in the direction of the spring 218, so that the limiting column 217 is separated from the second rack 216; after the second rack 216 loses its limiting function, it can be driven downward by the first gear 2141, and the impact vibration is reduced by the viscous damper 215, thereby improving the movement stability. When the connecting rod 22 rotates downward to reset, the first gear 2141 drives the second rack 216 to move upward to the highest point, and the limiting column 217 is re-engaged on the second rack 216 under the action of the spring 218 to limit, further improving the structural stability.

[0027] In another embodiment, the driving mechanism adopts an electric motor, a hydraulic motor or a rotary cylinder; the output end of the driving mechanism is connected to one of the connecting rods 22 of the rotating component 2.

[0028] In another embodiment, if Figure 7 As shown, the driving mechanism includes a third rack 82 and a hydraulic cylinder 81; the third rack 82 is slidably disposed in the support column 3, and the lower end of the third rack 82 is fixedly connected to the output end of the hydraulic cylinder 81; the end of the connecting rod 22 connected to the support column 3 is provided with a second rotating shaft 222, and the second rotating shaft 222 is fixedly provided with a second gear 83, and the second gear 83 is meshed with the third rack 82. The third rack 82 is pulled downward by the hydraulic cylinder 81, thereby causing the connecting rod 22 to rotate upward; the third rack 82 is pushed upward by the hydraulic cylinder 81, thereby causing the connecting rod 22 to rotate downward. The gravity of the third rack 82 is jointly constrained by the gravity of multiple composite panel assemblies 1, which reduces the work done to overcome gravity and saves driving energy. As a preferred embodiment, when the hydraulic cylinder 81 is pulled, it can be divided into two gears. When it is in the first gear, the top surface of the composite panel assembly 1 can be perpendicular to the outer surface of the building 4 (such as Figure 2 As shown), ventilation and shading are achieved to facilitate dehumidification or cooling of the outer surface of the building 4; when in the second gear, the composite panel assembly 1 can complete a 180° rotation.

[0029] In another embodiment, a temperature sensor 5, a light sensor 6 and a controller are further included; the temperature sensor 5, the light sensor 6 and the controller are all arranged outdoors; the temperature sensor 5, the light sensor 6 and the driving mechanism are all electrically connected to the controller. The temperature and light values ​​sensed by the temperature sensor 5 and the light sensor 6 are transmitted to the controller, so that the driving mechanism is controlled by the controller to drive the rotating assembly 2 to rotate, and finally the automatic rotation of the composite board assembly 1 is realized.

Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, belong to the protection scope of the present invention.
