[0025] In this embodiment: the cleaning device 6 is arranged on the surface of the steel door 2, and the cleaning device 6 includes a slide rail 61 and a cleaning rod 62. The slide rail 61 is fixedly connected to the surface of the steel door 2, and the cleaning rod 62 is slidably connected to the inner wall of the slide rail 61. The interior of the slide rail 61 is fixedly connected with a slide rod 63, and the cleaning rod 62 is slidably connected to the surface of the slide rod 63. A cleaning plate 67 is fixedly connected to the surface of the cleaning rod 62, and a threaded rod 64 is rotatably connected to the inner wall of the slide rail 61.

[0026] Specifically, a nut 65 is fixedly connected to the surface of the cleaning rod 62 , and the nut 65 is threadedly connected to the surface of the threaded rod 64 .

[0027] In this embodiment, the cleaning rod 62 can be moved by providing the nut 65, thereby reducing the movement trajectory of the cleaning rod 62 that cannot move up and down when the device is in use.

[0028] Specifically, both ends of the threaded rod 64 are fixedly connected with connecting caps 66 , and one end of the threaded rod 64 is fixedly connected with a connector 68 . The threaded rod 64 is provided to facilitate the movement of the nut 65 .

[0029] Specifically, one end of the connector 68 is fixedly connected to a motor 69 , and the motor 69 is fixedly connected to the surface of the steel door 2 . The motor 69 is provided to facilitate the rotation of the connector 68 .

[0030] In this embodiment: the inner wall of the steel door 2 is provided with a shielding device 7, the shielding device 7 includes a groove 71 and a shielding plate 72, the groove 71 is opened on the surface of the steel door 2, the shielding plate 72 is slidably connected to the inner wall of the groove 71, the surface of the groove 71 is provided with a slide groove 73, both ends of the slide groove 73 are provided with a clamping groove 75, the surface of the shielding plate 72 is provided with a pressing groove 74, and the inner wall of the pressing groove 74 is slidably connected with a clamping block 76.

[0031] In this embodiment, the shielding plate 72 is provided to shield the observation window 5, thereby reducing the risk of outsiders peeping into the observation window 5 when the device is in use.

[0032] Specifically, one end of the clamping block 76 is fixedly connected to a pressure rod 77 , and the clamping block 76 is clamped with the inner wall of the clamping slot 75 . The clamping block 76 is provided to facilitate limiting the shielding plate 72 .

[0033] Specifically, one end of the block 76 is fixedly connected to a spring 78 , and one end of the spring 78 away from the block 76 is fixedly connected to the inner wall of the pressing groove 74 . The spring 78 is provided to facilitate applying elastic force to the block 76 .

[0034] Working principle: When using the equipment, the user installs the equipment in some factories with higher safety factors to protect some high-risk areas. When the equipment needs to be used, the user starts the motor 69, and then the motor 69 rotates to drive the connector 68 to rotate, and the connector 68 rotates to drive the threaded rod 64 to rotate, and the threaded rod 64 rotates to drive the nut 65 to move, and the movement of the nut 65 drives the cleaning rod 62 to move, and the movement of the cleaning rod 62 drives the cleaning plate 67 to clean the surface of the observation window 5. By setting up the cleaning device 6, the surface of the observation window 5 is effectively cleaned, which plays a role in cleaning the surface of the observation window 5. When the equipment is in use, when the user uses the observation window 5 to observe the outside of the steel door 2, the outside of the observation window 5 is blocked by dust, causing the user to be unable to effectively and clearly observe the environment outside the steel door 2, thereby improving the practicability of the equipment.

[0035] When the device needs to be used, the user presses the pressure rod 77, and the pressure rod 77 moves to drive the block 76 to move.

By setting the shielding device 7, the observation window 5 is effectively shielded, which plays the role of closing the observation window 5, reducing the possibility that pedestrians walking by the steel door 2 can easily observe the inside of the steel door 2 when the device is in use, thereby exposing the internal environment technology, thereby improving the practicability of the device.
