[0025] Specific embodiment one: in combination with Figures 1 to 5 It is described that the embodiment, the protective door and window with the inner and outer double-layer shade curtain which can be self-adaptively adjusted in the embodiment includes a door and window body 1, an inner layer shade curtain assembly 2 and an outer layer shade curtain assembly 3, the inner layer shade curtain assembly 2 is arranged at the inner side of the door and window body 1, the upper end of the inner layer shade curtain assembly 2 is connected with an inner layer shade curtain driving mechanism 4, the outer layer shade curtain assembly 3 is arranged at the outer side of the door and window body 1, the upper end of the outer layer shade curtain assembly 3 is connected with an outer layer shade curtain driving mechanism 5, the outer side end of the door and window body 1 is provided with a wind meter 6, the inner side end of the door and window body 1 is provided with an illuminance sensor 7, the inner side of the door and window body 1 is provided with a controller, the inner layer shade curtain driving mechanism 4, the outer layer shade curtain driving mechanism 5, the wind meter 6 and the illuminance sensor 7 are electrically connected with the controller, the wind meter 6 controls the outer layer shade curtain driving mechanism 5 to drive the outer layer shade curtain assembly 3 to spread and retract through the controller, the illuminance sensor 7 controls the inner layer shade curtain driving mechanism 4 to drive the inner layer shade curtain assembly 2 to spread and retract through the controller.

[0026] The illuminance sensor 7 is designed to monitor the indoor light intensity, when the light intensity is higher than the determined value, the illuminance sensor 7 transmits the control signal to the controller, the controller controls the inner layer shade curtain driving mechanism 4 to start the forward rotation, the inner layer shade curtain driving mechanism 4 drives the inner layer shade curtain assembly 2 to spread, so as to realize the light shielding purpose.

[0027] The wind gauge 6 is used to monitor the outdoor wind strength. When the wind strength is higher than a certain value, the wind gauge 6 transmits a control signal to the controller, the controller controls the outer curtain driving mechanism 5 to start forward rotation, the outer curtain driving mechanism 5 drives the outer curtain assembly 3 to spread out, so as to achieve the purpose of protection. When the wind strength is lower than a certain value, the wind gauge 6 transmits a control signal to the controller, the controller controls the outer curtain driving mechanism 5 to start reverse rotation, the outer curtain driving mechanism 5 drives the outer curtain assembly 3 to retract.

[0028] In addition, the controller can also be manually adjusted to control the inner curtain driving mechanism 4 and the outer curtain driving mechanism 5, so as to achieve the expansion and retraction of the inner curtain assembly 2 and the outer curtain assembly 3, and meet the use requirements.

[0029] Specific implementation method two: combined with Figures 1 to 2 In this embodiment, the inner curtain assembly 2 includes an inner curtain 22, an upper fixed plate 23, a lower fixed plate 24, two inner limiting grooves 21 and two traction ropes 25. The two inner limiting grooves 21 are fixedly connected to the left and right sides of the inner side of the door and window body 1. The inner curtain 22 is arranged between the two inner limiting grooves 21. The upper end of the inner curtain 22 is fixedly connected to the upper fixed plate 23, and the lower end of the inner curtain 22 is fixedly connected to the lower fixed plate 24. The upper fixed plate 23 is horizontally fixedly connected to the upper part between the two inner limiting grooves 21. The lower fixed plate 24 is horizontally arranged between the two inner limiting grooves 21 and is slidingly connected along the height direction of the inner limiting groove 21. The two traction ropes 25 are arranged side by side. The lower end of the traction rope 25 is fixedly connected to a counterweight 26, and the counterweight 26 is fixedly connected to the lower end of the lower fixed plate 24. The upper end of the traction rope 25 is sequentially connected to the inner curtain driving mechanism 4 after passing through the lower fixed plate 24, the inner curtain 22 and the upper fixed plate 23. The technical features not disclosed in this embodiment are the same as those in the specific implementation method one.

[0030] In this way, when the inner curtain driving mechanism 4 pulls the traction rope 25 upwards, the lower fixed plate 24 drives the upper inner curtain 22 to move upwards along the inner limiting groove 21, and the inner curtain 22 is stacked between the lower fixed plate 24 and the upper fixed plate 23, so as to achieve the retraction of the inner curtain 22. Conversely, when the traction rope 25 is loosened, the counterweight 26 and the lower fixed plate 24 drive the lower end of the traction rope 25 to move downwards along the inner limiting groove 21 under the action of gravity, and the inner curtain 22 is spread out.

[0031] Specific implementation method three: combined with Figures 1 to 2To illustrate the present embodiment, the inner layer curtain driving mechanism 4 comprises a driving motor 41, a main roller shaft 42, a roller sleeve 43, an adjusting motor 44 and two winding rollers 45. The main roller shaft 42 is horizontally arranged at the upper end between the two inner layer limiting grooves 21 and rotationally connected with the inner layer limiting grooves 21. The driving motor 41 is arranged outside the main roller shaft 42. The output shaft of the driving motor 41 drives the main roller shaft 42 to rotate through a main transmission mechanism. The roller sleeve 43 is externally sleeved on one side of the main roller shaft 42 and rotationally connected with the main roller shaft 42. The adjusting motor 44 is arranged outside the roller sleeve 43. The output shaft of the adjusting motor 44 drives the roller sleeve 43 to rotate through an adjusting transmission mechanism. One winding roller 45 is respectively and fixedly sleeved on the roller sleeve 43 and the main roller shaft 42. The upper end of the traction rope 25 is wound around the winding roller 45 and fixedly connected with the winding roller 45. The technical features not disclosed in the present embodiment are the same as those in the second embodiment.

[0032] When the inner layer curtain 22 is normally spread, the driving motor 41 drives the main roller shaft 42 and the roller sleeve 43 to rotate in the positive direction. The two winding rollers 45 respectively release the two traction ropes 25. The counterweight 26 and the lower fixed plate 24 drive the lower end of the traction rope 25 to move downward along the inner layer limiting groove 21 under the action of gravity, thereby spreading the inner layer curtain 22. Conversely, the inner layer curtain 22 is retracted.

[0033] When the release lengths of the two traction ropes 25 are different, the lower fixed plate 24 will be inclined, which will cause interference or disengagement between the lower fixed plate 24 and the inner layer limiting groove 21. Therefore, when the inclination of the lower fixed plate 24 is found, the adjusting motor 44 can be turned on. The rotation of the adjusting motor 44 drives the roller sleeve 43 to rotate. The winding roller 45 on the roller sleeve 43 adjusts the traction rope 25 alone until the lower fixed plate 24 is adjusted to a horizontal state.

[0034] In the present embodiment, two distance sensors can be arranged below the lower fixed plate 24 to monitor the inclination of the lower fixed plate 24. When the reading monitored by the distance sensor is higher than a predetermined value, the distance sensor sends a control signal to the controller. The controller controls the adjusting motor 44 to automatically turn on to achieve automatic adjustment.

[0035] The output shaft of the adjusting motor 44 and the adjusting transmission mechanism are connected through a clutch 46.

[0036] In this way, when the driving motor 41 normally rotates, the clutch 46 is in a disconnected state to ensure the synchronous rotation of the roller sleeve 43 and the main roller shaft 42. When the lower fixed plate 24 needs to be adjusted, the clutch 46 is in a connected state and the adjusting motor 44 drives the roller sleeve 43 to rotate.
