Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Please see Figure 1 A preferred embodiment of this application illustrates an elevator shaft safety device comprising a safety door 1, a face recognition device 2, a monitoring camera 3, and a processor 4. The safety door 1 is located at the elevator shaft opening and can be opened and closed in a controlled manner. The face recognition device 2 is located beside the safety door 1 and is used to identify certified personnel. The monitoring camera 3 is located at the top of the safety door 1 and is used to monitor whether personnel are correctly wearing safety protective equipment. The processor 4 is connected to the face recognition device 2 and the monitoring camera 3.

[0021] According to the solution of this utility model embodiment, a face recognition device 2 is set up to identify certified staff members, and a monitoring camera 3 is set up to monitor whether staff members are wearing safety protective equipment correctly. This ensures that only staff members wearing safety protective equipment correctly can open the protective door 1 to enter the elevator shaft for work. This not only avoids the labor and time spent on the traditional disassembly and assembly of the protective door 1, but also prevents unauthorized personnel from entering, thus greatly improving safety.

[0022] The following detailed description uses specific examples:

[0023] Further, please see Figure 1 The elevator shaft opening has vertically aligned sliding rails 5 on both sides, and the safety door 1 has vertically aligned sliding pulleys 6 on both sides that cooperate with the sliding rails 5. The sliding pulleys 6 are limited within the sliding rails 5, and their cooperation with the sliding rails 5 drives the safety door 1 to move vertically back and forth. Next to the safety door 1 is a drive motor 7 connected to the processor 4. A drive rack is located on the side of the safety door 1 facing the drive motor 7, and a drive gear is located on the movable end of the drive motor 7 that meshes with the drive rack. The drive gear and drive rack cooperate to move the safety door 1.

[0024] Please see Figure 1The protective door 1 has movable slide rails 5 on both sides, corresponding to the vertical direction of the elevator shaft wall. Matching movable pulleys 6 are installed on the edges of the protective door 1, and a limiting structure ensures that the movable pulleys 6 always move within the movable slide rails 5, thereby achieving stable reciprocating movement of the protective door 1 in the vertical direction. This structure replaces the traditional detachable door hinge, enabling the protective door 1 to open and close quickly and smoothly, simplifying the construction and opening process. A drive rack is fixed to the side of the protective door 1 facing the drive motor 7, and a drive gear meshes with it. The drive motor 7 drives the drive gear to rotate, which in turn moves the drive rack and the entire protective door 1. This electric drive solution makes the opening and closing of the protective door 1 more precise and reliable.

[0025] Further, please see Figure 1 The protective door 1 is equipped with an indicator light 8 connected to the processor 4 at its top, used to indicate when the door is opened or closed. A buzzer, also connected to the processor 4, is also installed at the top of the protective door 1 for alarm purposes. The indicator light 8 changes from red to green when personnel pass facial recognition and correctly wear protective equipment, indicating that the door can be opened; if the conditions are not met, the light remains red and the door is prevented from opening. The buzzer at the top of the protective door 1 provides an audible and visual alarm when personnel are not wearing protective equipment or have not passed facial recognition, reminding workers and site managers to correct the situation promptly. This audible and visual alarm system plays a crucial role in preventing violations and ensuring construction safety.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
