Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 5The present invention provides a technical solution: the moving mechanism 100 includes a pair of fixed seats 1001, and a pair of moving grooves 1002 are opened on the opposite sides of the pair of fixed seats 1001, and the interiors of the pair of fixed seats 1001 are rotatably connected with bidirectional screw rods 1003, and the two ends of the pair of bidirectional screw rods 1003 are threadedly connected to the moving seats 1004, and the ends of the pair of moving seats 1004 away from the interior of the fixed seats 1001 extend to the interior of the moving groove 1002, and are clearance-matched with the moving groove 1002. The pair of moving seats 1004 at the same level are parallel to each other. The opposite sides are respectively connected to the outer walls of the fixed base 1001 at the same level. A worm gear 1005 is sleeved on the outer center of a pair of bidirectional screw rods 1003. A worm 1006 is rotatably connected to the inner part of a pair of fixed bases 1001 near the worm gear 1005. The worm 1006 and the worm gear 1005 are meshed with each other. A first motor 1007 is provided on the back of a pair of fixed bases 1001. The output ends of the two first motors 1007 are respectively connected to the pair of worm gears 1006. The outer sides of the two first motors 1007 and the two second motors 2008 are respectively connected to the outer sides of the two first motors 1007 and the two second motors 2008. The top and bottom of a pair of fixing seats 1001 are both connected to a mounting assembly 700, and the mounting assembly 700 includes a mounting seat 7001. A threaded hole 7002 is provided at the inner center of the mounting seat 7001.

The movable seat 1004 moves toward each other under the sliding action of the movable groove 1002. Since a pair of movable seats 1004 and the fixed seat 1001 at the same level are connected, when the two pairs of movable seats 1004 move toward each other, the pair of fixed seats 1001 will move toward each other. By setting the mounting seat 7001 and opening a threaded hole 7002 inside the mounting seat 7001, it is convenient to fix the mounting seat 7001 and the fixed seat 1001 inside the distribution box where electrical appliances are installed through fasteners, thereby performing fire monitoring and early warning for the electrical appliances inside the distribution box.

[0037] Specifically, the working principle of the electrical fire warning device based on smoke detection is as follows: when in use, by setting a mounting base 7001 and opening a threaded hole 7002 inside the mounting base 7001, it is convenient to fix the mounting base 7001 and the fixing base 1001 inside the distribution box where the electrical appliances are installed through fasteners, thereby performing fire monitoring and early warning on the electrical appliances inside the distribution box.

The rods 1003 rotate simultaneously, so that the movable seats 1004 threadedly connected to the opposite threads at both ends of a pair of bidirectional screw rods 1003 can move in opposite directions under the sliding action of the movable groove 1002. Since the pair of movable seats 1004 and the fixed seat 1001 at the same level are connected, when the two pairs of movable seats 1004 move in opposite directions, the pair of fixed seats 1001 can move in opposite directions. When the two second motors 2008 are started, it is easy to drive the pair of rotating shafts 2004 to rotate, so as to realize the rotation of the gear 2005 set on one end thereof, thereby making the rack 2000 meshing above the gear 2005 rotate. 6 and the rack 2006 meshing with the lower part realize stable opposite movement under the sliding action of the limit bar 2007. When a pair of racks 2006 inside a fixing seat 1001 move toward each other, the pair of sliders 2003 will be moved toward each other, thereby driving a pair of connecting plates 300 and the infrared thermal imager 400 to move toward each other, so that the detection range of the infrared thermal imager 400 is expanded, thereby improving the detection efficiency. By setting up the infrared thermal imager 400, if the electrical equipment has poor contact or the wear of the mechanical parts may cause local overheating, it can be detected by the infrared thermal imager 400, and the infrared thermal imager 400 can detect it. The external thermal imager 400 can check the temperature of the electrical connector in a non-contact manner to determine whether a fire will occur, and thus issue an early warning.
