[0039] The radar warning lamp 3 is provided on at least one of said fireproof doors 1, said radar warning lamp 3 projects a line on the ground in front of said fireproof door 1, and is used for monitoring the approach of the moving object in front;

[0040] The sound and light integrated alarm lamp 4 is connected with the main box of said radar warning lamp 3, and when said radar warning lamp 3 detects the approach of the moving object, said sound and light integrated alarm lamp 4 gives an alarm;

[0041] The rotating frame 5 has two, and one said rotating frame 5 is rotatably arranged at the front end of each said fireproof door 1;

[0042] The safety plate 6 has two, and one said safety plate 6 is rotatably arranged at the end of each said rotating frame 5, when said rotating frame 5 is rotated to open to the horizontal state, said safety plate 6 is in the vertical state and located in front of said fireproof door 1.

[0043] The line is red.

[0044] In use, the mine tunnel has a mounting position of the fireproof door 1, the structure of the fireproof door 1 itself is prior art, and the prior art means can be used to install the opposite opening fireproof door 1. The warning lamp adopts an "X" type, facing forward, and the construction personnel can clearly know the warning information of this place. The radar warning lamp 3 includes a projection module and a radar monitoring module, which can project a line on the ground in front, and has a certain width, and the construction personnel can clearly observe the warning of the line. At the same time, the position of the line is also the radar monitoring boundary. When the construction personnel steps into the line, the radar monitoring module detects the approach of the moving object, sends a signal to the sound and light integrated alarm lamp 4 through the main box, and the sound and light integrated alarm lamp 4 starts to flash and give an alarm sound, prompting the construction personnel not to approach.

[0045] The rotating frame 5 is upwardly rotated to open, and when the rotating frame 5 is rotated to the horizontal state and approaches the horizontal state, the safety plate 6 is rotated to the front of the fireproof door 1, and the safety plate 6 and the fireproof door 1 have a spacing therebetween, so as to realize physical isolation. The safety plate 6 is arranged on the front side of each fireproof door 1, and the isolation requirement of the front side can be met.

[0050] The connecting ear 101 can be close to the middle upper position, and when the rotating frame 5 is opened, the rotating frame 5 can be close to the horizontal state and be in the inclined downward state, and the locking force is provided through the friction force. When there is a very large impact force to collide with the safety plate 6 by mistake, the rotating frame 5 can be downwardly rotated to overcome the friction force of the locking bolt 502, so as to reduce the direct impact damage of the impact force, and play a safety buffering role.

[0051] Further, the side of the rotating frame 5 away from the connecting ear 101 has a hanging hole 503, and the upper portion of the safety plate 6 has a hanging shaft 601, and the hanging shaft 601 is rotationally connected with the hanging hole 503.

[0052] In use, the hanging shaft 601 of the upper portion of the safety plate 6 is in a "7" shape or an inverted "L" shape, and is hung on the rotating frame 5 through the rotating connection structure. Under the action of the gravity of the safety plate 6, when the rotating frame 5 is rotated, the safety plate 6 is always in the vertical state.

[0053] Further, the front end of the safety plate 6 is provided with a warning belt 602.

[0054] In use, the safety plate 6 is always in vertical state, and the front side is provided with a warning tape 602, which can be a reflective warning tape 602, capable of safe warning.
