[0001] The present invention relates to the technical field of construction equipment, and specifically relates to an automatic sunshading device and method for building exterior windows. Background Art

[0002] Building exterior windows are the main components for building lighting and ventilation. However, the sunshading effect and the heat insulation and heat preservation performance of glass windows are poor, which will cause a large amount of solar radiation heat to enter the room in summer, resulting in high cooling energy consumption, and a large amount of heat dissipation in winter, resulting in high heating energy consumption. Existing sunshading devices have a single function. For example, curtains, blinds, etc. all require manual operation and cannot automatically adjust the sunshading effect according to the temperature change within a day, and the sunshading effect is limited. Therefore, in view of this, the present invention proposes an automatic sunshading device and method for building exterior windows to make up for and improve the deficiencies of the existing technology.

While the hot air stored in the heat preservation chamber can be dissipated, the sunshade strips can be automatically controlled to fold and ventilate at night. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Embodiment 2 of the present invention An automatic shading method for building exterior windows comprises the following steps: Step 1: Pour a proper amount of water into the liquid storage tank 314, and adjust the temperature sensor 317 according to the relevant temperature of the season, so that it sends a driving signal to the photoelectric converter 316 when the temperature is high during the day, and sends a stop signal to the photoelectric converter 316 when the temperature is low at night; Step 2: When the temperature is high during the day, the heating tube 315 receives a driving signal to heat the water flow poured into the liquid storage tank 314, so that part of the expanded gas discharged by the heating and temperature rise squeezes the piston column 310 forward until it moves to the minimum contraction distance of the return spring 38, and the plurality of sunshade strips 4 are linked to be laid flat for sunshade, and at this time, the other part is discharged through the exhaust hole 312 to the heat preservation chamber formed between the window frame 2 and the building outer window for storage; Step 3: When the temperature is relatively low at night, the heating pipe 315 receives a stop signal to interrupt heating. At this time, the restoring force of the restoring spring 38 is greater than the thrust generated by the expanding gas squeezing the piston column 310, causing the piston column 310 to move backward after resetting, and driving several sunshade strips 4 to fold and ventilate.

[0018] Working principle and usage process of the present invention: For the convenience of description and understanding, this working process is mainly described in the laying state and the folding state: Preliminary preparation: Pour an appropriate amount of water flow into the liquid storage tank 314, and debug the temperature sensor 317 according to the relevant temperature of the season, so that when the daytime temperature is relatively high, it sends a driving signal to the photoelectric converter 316, and when the nighttime temperature is relatively low, it sends a stop signal to the photoelectric converter 316; In the laying state: When the daytime temperature is relatively high, the sun shines on the solar panel 320, and the photoelectric converter 316 converts the sunlight received by the solar panel 320 into electrical energy for storage. After receiving the driving signal sent by the temperature sensor 317, it controls the heating pipe 315 to heat the water flow poured into the liquid storage tank 314, and the part of the expanding gas discharged by heating and raising the temperature squeezes the piston column 310 to move forward until it moves to the minimum contraction distance of the restoring spring 38. Since the bottom end of the rotating rod 35 is fixedly connected to the secondary bevel gear 36, and the secondary bevel gear 36 meshes and cooperates with the primary bevel gear 34, the top end of the rotating rod 35 is fixedly connected to the tooth column 37, and several rotating shafts 31 are fixedly connected to the gear discs 32, several gear discs 32 mesh with a chain 33, and one of the gear discs 32 is fixedly connected to the primary bevel gear 34, prompting several sunshade strips 4 to lay and rotate along with the forward movement of the piston column 310, and the other part is discharged through the exhaust hole 312 into the heat preservation chamber formed between the window frame 2 and the building exterior window for storage; In the folding state: By reverse deduction from the above working process, when the temperature is relatively low at night, the heating pipe 315 receives a stop signal to interrupt heating. At this time, the restoring force of the restoring spring 38 is greater than the thrust generated by the expanding gas squeezing the piston column 310, causing the piston column 310 to move backward after resetting, thereby driving several sunshade strips 4 to fold and ventilate.
