Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Such as Figures 1 to 5As shown in the figure, this embodiment proposes a building construction safety protection device with self-locking, including a frame 1. A fixing plate 2 is connected to the back of the frame 1 by welding. A connecting shaft 4 is connected to the inside of the frame 1 by welding. Both ends of the connecting shaft 4 are connected to a door panel 3 through bearings. A password plate 10 is connected to the front side of the frame 1 by screws. A locking mechanism 9 is connected to the right side of the frame 1 by screws. An infrared induction module 11 is connected to the back of the frame 1 by screws. A buzzer 12 is connected to the back of the frame 1 by screws. An upper support plate 5 and a lower support plate 6 are connected to the inside of the frame 1 by welding. A connecting column 7 is connected between the upper support plate 5 and the lower support plate 6. The outer wall surface of the connecting column 7 is movably sleeved with a spring 8. By setting a self-locking mechanism, a first motor 905 drives a gear 906 to rotate. The gear 906 meshes with a tooth groove 907. A lock block 903 slides inside a chute block 902. The lock block 903 extends or retracts synchronously under the rotation of the first motor 905. When locking the door panel 3, the lock block 903 extends and passes through the lock groove 13 of the door panel 3 into the inside of the frame 1, thus completing self-locking and realizing the automatic opening and closing of the door lock. This not only improves the operation convenience but also reduces errors and delays in manual operations. In addition, the design of the spring 8 ensures that the door can automatically return to the closed position after being opened, further improving the self-locking ability of the door.

[0025] As Figures 1 to 5 shown, the locking mechanism 9 includes a housing 901, a chute block 902, a lock block 903, a boss 904, a first motor 905, a gear 906, and a tooth groove 907. A housing 901 is connected to the right side of the frame 1 by welding. A chute block 902 is arranged inside the housing 901. A lock block 903 is slidably connected inside the chute block 902. A boss 904 is connected to the bottom of the housing 901 by welding. A first motor 905 is connected to the top of the boss 904 by screws. The output end of the first motor 905 is connected to a gear 906 by a key. A tooth groove 907 is arranged on the inner wall surface of the lock block 903. The gear 906 meshes with the tooth groove 907. By setting a password plate 10, an infrared induction module 11, and a buzzer 12, the door will only be unlocked by entering the correct password, effectively preventing unauthorized personnel from entering. The addition of the infrared induction module 11 further enhances the security. It can issue an alarm when detecting unauthorized personnel and notify the management personnel in time, helping to prevent safety accidents.

[0026] As Figures 1 to 5As shown in the figure, the password panel 10 is electrically connected to the first motor 905. The password panel 10 is electrically connected to the infrared induction module 11. The infrared induction module 11 is electrically connected to the buzzer 12. A through hole is provided in the middle of the fixing plate 2 and is fixedly connected to the wall through bolts. According to the construction site with different widths, the widths and heights of the frame body 1 and the door panel 3 are adjusted. The middle of the door panel 3 is made of stainless steel mesh. A lock groove 13 is provided through one side of the door panel 3, and the lock groove 13 cooperates with the lock block 903. The bottom of the spring 8 is welded to the door panel 3, and the top of the spring 8 is welded to the frame body 1. The first motor 905 is a bidirectional rotating motor with a self-locking function, and the door panel 3 can be locked and opened by bidirectional rotation.

[0027] Working principle:

[0028] First, the staff fixes the fixing plate 2 to the wall through bolts. By entering the password on the password panel 10, when the password is correct, the first motor 905 rotates forward. The first motor 905 drives the gear 906 to rotate. The gear 906 meshes with the tooth groove 907, and the lock block 903 rotates backward and retracts into the housing 901. The staff can open the door lock and enter the construction site by pulling the door panel 3. When the self-locking mechanism is opened, the buzzer 12 beeps slowly. While the staff pulls the door panel 3, the spring 8 is stretched. When the staff enters, the door panel 3 is pulled back to its original position by the rebound of the spring 8, and the door panel 3 is locked by the self-locking mechanism; by setting the self-locking mechanism, the first motor 905 drives the gear 906 to rotate. The gear 906 meshes with the tooth groove 907, and the lock block 903 slides inside the chute block 902. The lock block 903 extends or retracts synchronously with the rotation of the first motor 905. When locking the door panel 3, the lock block 903 extends and passes through the lock groove 13 of the door panel 3 into the inside of the frame body 1, and the self-locking can be completed, realizing the automatic opening and closing of the door lock. This not only improves the convenience of operation but also reduces errors and delays in manual operation. In addition, the design of the spring 8 ensures that the door can automatically return to the closed position after being opened, further improving the self-locking ability of the door;

[0029] When the staff member goes out from the inside, when the infrared sensing module 11 senses the infrared signal of the human body, it controls the first motor 905 to rotate forward, opens the self-locking mechanism, and pushes the door panel 3 to leave the area. At the same time, under the resilience of the spring 8, the door panel 3 is pulled back to its original position. When all the internal staff have left and the door lock is changed to the protection mode through the password panel 10, at this time, the infrared sensing module monitors. When it senses the infrared signal of the human body, it emits an alarm sound through the buzzer 12, and at the same time alarms through the password panel 10, prompting the management personnel that there are people breaking into the construction site. By setting the password panel 10, the infrared sensing module 11 and the buzzer 12, the door will only unlock through the correct password input, effectively preventing the entry of unauthorized personnel. The addition of the infrared sensing module 11 further enhances the security, can emit an alarm when detecting unauthorized personnel, and notify the management personnel in time, which helps to prevent the occurrence of safety accidents.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
