Fire protection settings refer to the automatic fire alarm system in the building. The automatic fire alarm system includes smoke sensors. Smoke sensors are used to detect smoke concentration to prevent fires and are widely used in various fire alarm systems. In order to ensure fire safety, smoke sensors need to be tested regularly.

[0003] Generally, fire safety passages need to be protected from being occupied before a fire occurs, so as to avoid failure to achieve the corresponding effect when a fire occurs. Existing monitoring requires manual monitoring, which is not timely enough. In addition, due to the human walking in the safety passage, dust easily sticks to the monitor, thus affecting the monitoring effect of the monitor. In view of this, we propose a fire monitoring device and monitoring system for building safety passages. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The fire monitoring device and monitoring system for building safety passages are provided with a protective cover on the outside of the monitoring probe, and when dust appears on the outside of the protective cover, the dust sensor is automatically triggered, thereby turning on the micro motor. After the micro motor is turned on, the meshing action of the driving gear and the driven gear can make the adapter sleeve rotate, thereby driving the protective cover to rotate. When the protective cover rotates, the brush rod fixed on the fixed sleeve will clean the dust on the outside of the protective cover during the rotation of the protective cover; at the same time, through the scraper rod, the brush rod will produce a certain rotation during the rolling of the protective cover, thereby causing a certain deformation of the torsion spring arranged inside it.

[0036] See also Figure 2 and Figure 5 , the dust cleaning component 7 is installed on the adapter sleeve 62, and the dust cleaning component 7 includes a sliding seat 71 and a piston cylinder 72. The piston cylinder 72 is fixedly installed inside the fixed sleeve 3. The inner side of the sliding seat 71 is connected with a screw sleeve 76 through a bearing. The screw sleeve 76 is connected to the adapter sleeve 62 through a thread. The inner side of the fixed sleeve 3 is provided with a guide rod 68 for guiding the sliding seat 71 in an annular shape. The fixed sleeve 3 is provided with a lug plate 73 on the side corresponding to the support frame 1. The lug plate 73 is installed with a scraper rod 74 and a brush rod 75.
