[0060] In use, the outdoor temperature value is detected in real time by using the temperature sensor, when the detected temperature value is greater than the set first temperature threshold value, the motor 209 is started to drive the traction rod 207 to rotate, the base 204 is driven downward by winding the traction rope 206, and the heat insulation plate 203 is driven downward by the rotation of the reel 201, after the base 204 moves to the bottom of the air cavity wall 103, the joint 302 is completely connected with the liquid inlet head 306, the motor 209 stops rotating, then the electric telescopic part 403 is started to drive the two top positioning plates 401 on both sides to fold towards the heat insulation plate 203, the top of the stretched-out heat insulation plate 203 is positioned by being pressed and abutted on both sides, and the two side positioning plates 402 on both sides of the heat insulation plate 203 are pressed and abutted on both sides by the movement of the top positioning plate 401, so as to position the two sides of the heat insulation plate 203, thereby realizing the overall fixation of the heat insulation plate 203 and preventing the heat insulation plate 203 from resetting.

[0062] The liquid supply assembly 3 further comprises an air pump 304 and a telescopic bag 3041, the air pump 304 is arranged on the bottom surface of the movable frame 1, the telescopic bag 3041 is arranged on the inner bottom surface of the liquid storage tank 301, the telescopic bag 3041 is communicated with the gas conveying end of the air pump 304 through a hose, the base 204 is provided with a heat insulation cavity 305, the heat insulation cavity 305 is used for the entry and distribution of the heat insulation liquid, the middle part of the heat insulation plate 203 is provided with a hollow layer 307, the hollow layer 307 is used for being filled with the heat insulation liquid, the bottom of the heat insulation cavity 305 is provided with a liquid inlet head 306, the top of the heat insulation cavity 305 is provided with a filling head 308 communicated with the hollow layer 307, and the filling head 308 is provided with a control valve.

[0063] Specifically, after the base 204 is completely lowered, the bottom surface is in contact with the bottom surface of the air cavity wall 103, while the liquid inlet head 306 is inserted into the docking head 302 to complete the docking, and then the liquid supply valve 303 and the control valve are opened, the air pump 304 is started to supply air to the telescopic bag 3041, so that the telescopic bag 3041 is elongated upward, and the heat insulation liquid is pushed upward to flow into the heat insulation cavity 305 through the docking head 302 and the liquid inlet head 306.

[0065] Embodiment 2

Therefore, the following improvements are made:

[0069] In use, when one side of the light sensor 106 detects that the light intensity on that side is high, before injecting the heat insulation liquid into the hollow layer 307, the top positioning plate 401 on both sides of the heat insulation plate 203 is first driven away from the heat insulation plate 203 by the electric telescopic part 403 to remove the extrusion and interference of the heat insulation plate 203, and at the same time, the downward traction force of the heat insulation plate 203 is provided by the motor 209 to prevent the heat insulation plate 203 from being rewound and reset upward, and then the electromagnetic slide rail 404 on one side of the heat insulation plate 203 is started synchronously to drive the two side positioning plates 402 on that side to move along the width direction of the heat insulation plate 203, and the side positioning plates 402 stop after moving to the middle part of the heat insulation plate 203, and then the top positioning plate 401 on both sides is driven again by the electric telescopic part 403 to extrude and interfere on both sides of the top of the heat insulation plate 203, and at the same time, the side positioning plates 402 extrude and interfere in the middle part of the heat insulation plate 203, and the corresponding extrusion and interference of the side positioning plates 402 on both sides of the heat insulation plate 203 divides the hollow layer 307 in the heat insulation plate 203 into multiple chambers, and each chamber corresponds to a filling head 308, and then the liquid supply valve 303 and the control valve are opened, and the flux of the control valve on the side with high light intensity is greater than that on the side with low light intensity, so that more heat insulation liquid enters the chamber on the side with high light intensity when the heat insulation liquid is injected into the hollow layer 307, thereby increasing the heat insulation effect of the heat insulation plate 203 and further increasing the heat insulation effect of the heat insulation plate 203 close to the side with high light intensity, thereby improving the heat insulation efficiency, achieving precise heat insulation, avoiding uneven heat insulation, and adjusting the position of the side positioning plate 402 in real time to accurately adjust the heat insulation strength of the heat insulation area to the greatest extent.

[0070] Embodiment 3

[0072] S1, the temperature sensor detects the outdoor temperature in real time, and when the detection value is greater than the first temperature threshold, the motor 209 drives the traction rod 207 to rotate, and the bottom plate 204 and the heat insulation plate 203 are moved downward by winding the traction rope 206;

[0073] Specifically, when the motor 209 drives one side of the traction rod 207 to rotate, the other side of the traction rod 207 is synchronously driven to rotate through the connecting rod 208, so that the two traction ropes 206 are synchronously wound; the sliding block 205 at both ends of the bottom plate 204 slides along the side wall of the air cavity wall 103 to ensure that the heat insulation plate 203 is vertically lowered; the reel 201 rotates synchronously with the unwinding of the heat insulation plate 203, and the spiral spring 202 stores potential energy by elastic contraction, until the bottom surface of the bottom plate 204 contacts the bottom of the air cavity wall 103, at which time the heat insulation plate 203 is completely unfolded to cover the glass area.

[0075] Specifically, the electric telescopic part 403 is extended to push the two side top positioning plates 401 to slide along the top surface of the air cavity wall 103 until the two side top positioning plates 401 tightly fit the top and the two sides of the heat insulation plate 203 to close the gap between the heat insulation plate 203 and the air cavity wall 103; at the same time, the electromagnetic slide rails 404 at the bottom of the top positioning plates 401 drive the side positioning plates 402 to fold towards the two sides of the heat insulation plate 203, and each of the two side positioning plates 402 fits the two side surfaces of the heat insulation plate 203 to form a full-range fixation of the top and the side of the heat insulation plate 203 to prevent the heat insulation plate 203 from resetting under the action of the vortex spring 202.

[0076] S3, when the temperature sensor detects that the outdoor temperature is greater than the second temperature threshold, the liquid supply valve 303 and the control valve are opened, the air pump 304 is started to inflate the telescopic bag 3041, the heat insulation liquid enters the hollow layer 307 to enhance the heat insulation effect, and the heat insulation strength is adjusted by controlling the amount of the heat insulation liquid injected;

[0077] Specifically, the heat insulation liquid stored in the liquid storage tank 301 is transparent ATO solution, the air pump 304 inflates the telescopic bag 3041 to squeeze the heat insulation liquid in the liquid storage tank 301, and the heat insulation liquid enters the heat insulation cavity 305 of the base 204 through the joint 302 and the liquid inlet head 306; the heat insulation liquid flows into the hollow layer 307 of the heat insulation plate 203 through the filling head 308 at the top of the heat insulation cavity 305, and the thickness of the heat insulation liquid in the hollow layer 307 increases with the increase of the injection amount, and the double heat insulation is formed by combining the material of the heat insulation plate 203; when the outdoor temperature decreases, the air pump 304 deflates the telescopic bag 3041 to make the heat insulation liquid flow back to the liquid storage tank 301, the amount of the liquid in the hollow layer 307 is reduced, and the heat insulation strength is reduced.

[0078] S4, when the light intensity on one side of the fixed frame 105 is high, the top positioning plate 401 is first moved away from the heat insulation plate 203 by the electric telescopic part 403, the heat insulation plate 203 is temporarily positioned by the traction of the motor 209, then the side positioning plates 402 on the two sides are driven to move to the middle of the heat insulation plate 203 by the electromagnetic slide rails 404 on one side, and then the top positioning plate 401 and the side positioning plates 402 are driven to restore the positioning of the heat insulation plate 203 by the electric telescopic part 403, at this time, the hollow layer 307 is divided into multiple chambers;

[0079] Specifically, the light sensors 106 on both sides of the activity box 1 detect the light intensity on both sides respectively, when the light value on one side is significantly higher than the other side, the electric telescopic part 403 is retracted to make the top positioning plate 401 disengage from the heat insulation plate 203, the motor 209 keeps the traction force on the traction rope 206 to prevent the heat insulation plate 203 from moving up; the electromagnetic slide rail 404 on the side with lower light intensity is started, and the sliding part drives the side positioning plate 402 to slide along the bottom surface of the top positioning plate 401 to the middle of the heat insulation plate 203, and the two side positioning plates 402 are symmetrically distributed; the electric telescopic part 403 is started again to make the top positioning plate 401 and the side positioning plate 402 re-clamp the heat insulation plate 203, at this time the side positioning plate 402 divides the hollow layer 307 into multiple independent chambers, corresponding to the high light intensity area and the low light intensity area respectively.

[0080] S5, open the liquid supply valve 303 and the control valve, make the flux of the control valve on the side with high light intensity greater than that on the side with low light intensity, inject the heat insulation liquid into the corresponding chamber, and realize differential precise heat insulation.

[0081] Specifically, when supplying liquid, the filling head 308 control valve on the side with high light intensity has a larger opening degree, more heat insulation liquid flows into the hollow layer 307 of the corresponding chamber, and the thickness of the heat insulation liquid in this area is increased; the control valve on the side with low light intensity has a smaller opening degree, and the liquid injection amount is reduced; since the heat insulation plate 203 and the heat insulation liquid are both transparent materials, the light transmittance of the door and window will not be affected; in this way, the heat insulation effect of the high light intensity area is more remarkable through the local strengthening mode.

[0082] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
