[0049] Example 2

[0050] On the basis of the first embodiment, the second embodiment further includes:

[0051] A sealing gasket 10 is provided on the bottom side of the installation frame 4 and is sealed to the top side of the top frame 3. A sealing gasket 10 is also provided on the bottom side of the installation frame 4 and is sealed to the top side of the top frame 3, so that when the installation frame 4 and the glass body 6 are closed, external dust and rainwater can be effectively prevented from entering the basement through the gap between the installation frame 4 and the top frame 3, thereby ensuring the normal operation and service life of the system.

[0052] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 8 and the electric push rod 21 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0053] The working principle and use process of this technical solution are as follows: when in use, first, the basement body 1 serves as the main body of the system, and a ventilation shaft 2 is designed on its top. Ventilation holes 16 are provided on both sides of the ventilation shaft 2. One side of the inner wall of each vent 16 is connected to multiple louvers 17 through a rotating shaft. The louvers 17 can be adjusted in angle under the action of an adjustment mechanism to control the ventilation volume and protection. A top frame 3 is fixed on the top side of the ventilation shaft 2, and the top of the top frame 3 is connected to a mounting frame 4 through a hinge. A fixing groove 5 is provided inside the mounting frame 4, and a glass body 6 is installed in the fixing groove 5, which is used to achieve covering protection without affecting the lighting inside the basement. When the angle of the louver 17 needs to be adjusted, the electric push rod 21 starts to work, and the output end of the electric push rod 21 pushes The driving plate 22 moves, thereby driving the driving bar 23 to move. A plurality of teeth 24 are fixed on one side of the driving bar 23, and the teeth 24 mesh with the gear 19 fixed on one end of the driving rod 18. Therefore, when the driving bar 23 moves, the gear 19 is driven to rotate, thereby driving the driving rod 18 and the shutter blade 17 to rotate, so as to achieve the angle adjustment, thereby achieving the purpose of automatically adjusting the angle and opening and closing, avoiding the need for manual operation, and improving convenience. In order to increase the stability of the structure, the fixing plate 25 is fixedly arranged on the bottom side of the driving bar 23, and the top end of the telescopic rod 26 is connected to the bottom side of the fixing plate 25, and the bottom end is fixed to the bottom side of the inner wall of the mounting groove 20, so that the telescopic rod 26 can provide a certain limit support when the driving plate 22 moves, further improving the stability;

[0054] In addition, two connecting rods 27 are provided between the top side of the driving plate 22 and the bottom side of the mounting frame 4. The bottom end of each telescopic rod 26 is hinged to the top side of the driving plate 22, and the top end is hinged to the bottom side of the mounting frame 4, which is conducive to supporting and controlling the mounting frame 4. At the same time, two limiting grooves 28 are provided on the top side of the top frame 3 for the connecting rods 27 to penetrate and limit the sliding. Then, when the shutter blades 17 need to be closed on rainy days or in weather with many mosquitoes, the mounting frame 4 and the glass body 6 can be driven to rotate and close synchronously, and can also be opened synchronously, so that the ventilation shaft 2 can further enhance the ventilation and achieve an integrated effect, which not only enhances the convenience but also improves the applicability. The bottom side of the mounting frame 4 is also provided with a sealing gasket 10 that is sealed and fitted with the top side of the top frame 3, so that when the mounting frame 4 and the glass body 6 are closed, it can effectively prevent external dust and rainwater from entering the basement through the gap between the mounting frame 4 and the top frame 3, thereby ensuring the normal operation and service life of the system.

[0055] When the glass body 6 needs to be wiped, the motor 8 starts to work, and the output end of the motor 8 drives the screw rod 9 to rotate through the coupling. The threaded frame 11 is threadedly connected to the outer wall of the screw rod 9. Therefore, when the screw rod 9 rotates, it will drive the threaded frame 11 to move on the screw rod 9, and the cleaning cotton 12 is clamped and installed on the inner wall of the threaded frame 11. As the threaded frame 11 moves, the cleaning cotton 12 will wipe and clean the surface of the glass body 6, thereby achieving the effect of automatic wiping and cleaning, and avoiding that a lot of dust is attached to the surface of the glass body 6 after long-term use, which greatly affects the glass body. 6, which improves convenience. In order to ensure the stability of the threaded frame 11 during movement, the fixing frame 15 is fixedly arranged on the top side of the mounting frame 4, and the end of the screw rod 9 away from the motor 8 is rotatably connected to one side of the fixing frame 15 through a rotating shaft. At the same time, the limiting rod 14 is fixedly arranged on one side of the fixing frame 15 and extends to the inside of the protective frame 7. A limiting hole 13 is also provided inside the threaded frame 11 for limiting the sliding of the limiting rod 14, thereby ensuring that the threaded frame 11 will not deviate from the track during movement, thereby improving stable movement and wiping, and facilitating use.
