Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, a mobile fire early warning device includes an intelligent vehicle 1, which is used to move an infrared camera 14 along a set route for inspection.

[0024] The top of the intelligent vehicle 1 is equipped with a rotating seat 2 driven by a power unit, and the axis of rotation of the rotating seat 2 extends vertically. The power unit is specifically a power motor 3 that is bolted to the inside of the intelligent vehicle 1. The axis of rotation of the power motor 3 extends upward to the outside of the intelligent vehicle 1. The rotating seat 2 is circular and coaxially fixed to the upper end of the rotating axis of the power motor 3. The power motor 3 drives the rotating seat 2 to rotate, thereby causing the rotating seat 2 to drive the infrared camera 14 to rotate in the horizontal direction, adjusting the horizontal orientation of the infrared camera 14.

[0025] A portal frame 4 is fixedly installed on the top of the rotating seat 2. The frame 4 includes two vertically extending guide rail boxes 5 arranged opposite each other on the left and right. The lower end of the guide rail box 5 is fixedly installed on the top of the rotating seat 2 by bolts, and a top plate 6 is fixedly installed on the upper end of the two guide rail boxes 5 by bolts. The support frame 4 is equipped with a mounting bracket 7 that moves vertically driven by a drive mechanism. The mounting bracket 7 is U-shaped with an open front end, and the two guide rail boxes 5 are open on opposite sides. The mounting bracket 7 is located between the two guide rail boxes 5. A vertically extending slide rod 8 is fixedly installed in the guide rail box 5 on the right side by bolts. A matching slide seat 10 is fixedly installed on the right side of the mounting bracket 7 by bolts. The drive mechanism includes a drive motor 11, which is bolted to the inner side of the bottom wall of the left guide rail box 5. An upwardly extending lead screw 12 is fixedly connected to the rotating shaft of the drive motor 11 by a coupling. The upper end of the lead screw 12 is connected to the top wall of the corresponding guide rail box 5 by a bearing. A matching lead screw nut 13 is fixedly installed on the left side of the mounting bracket 7 by bolts. The drive motor 11 drives the lead screw 12 to rotate, and the lead screw 12 acts on the lead screw nut 13 and drives the mounting bracket 7 to slide up and down along the slide rod 8, thereby adjusting the height of the infrared camera 14.

[0026] The mounting bracket 7 houses an infrared camera 14 that swings vertically in a vertical plane, driven by an adjustment mechanism. The infrared camera 14 is wirelessly connected to a control center. When the infrared camera 14 detects a fire, it sends a signal to the control center to notify personnel to extinguish the fire. Initially, the infrared camera 14 faces directly forward. Figure 3 As shown, horizontally extending mounting shafts 15 are fixedly installed on the left and right sides of the infrared camera 14. The axis of the mounting shafts 15 extends laterally perpendicular to the shooting direction of the infrared camera 14. The two mounting shafts 15 are rotatably mounted on the inner wall of the mounting frame 7 via bearings. The adjustment mechanism includes an adjustment motor 16 bolted to one side of the mounting frame 7. The rotation shaft of the adjustment motor 16 is parallel to the mounting shafts 15, and the rotation shaft of the adjustment motor 16 is connected to one of the mounting shafts 15 via a belt 17. The adjustment motor 16 drives the mounting shaft 15 on one side of the mounting frame 7 to rotate via the belt 17, thereby causing the mounting shaft 15 to drive the mounting frame 7 and the infrared camera 14 to swing up and down, adjusting the orientation of the infrared camera 14 in the vertical direction.

[0027] The infrared camera 14 is equipped with a mounting plate 18 that is driven to swing by a reciprocating mechanism. The plane in which the mounting plate 18 rotates is parallel to the shooting direction of the infrared camera 14. Specifically, as shown in the figure... Figure 4As shown, a mounting base 19 is fixedly installed at the bottom of the infrared camera 14 by bolts. A connecting shaft 20 is vertically rotatably mounted at the front bottom of the mounting base 19 by bearings. The connecting shaft 20 is perpendicular to the shooting direction of the infrared camera 14 and perpendicular to the mounting shaft 15. The mounting plate 18 has a horizontal part and a vertical part extending downward from the front end of the horizontal part. The horizontal part of the mounting plate 18 is fixedly installed at the lower end of the connecting shaft 20 by bolts. A nozzle 21 for spraying water mist in front of the infrared camera 14 is fixedly installed on the vertical part of the mounting plate 18 by nuts.

[0028] A water tank 22 is bolted to the top of the rotating base 2. A hose 23 connects the water tank 22 to the water inlet of the nozzle 21. A water pump 24 is connected to the hose 23 and bolted to the top of the rotating base 2. When the infrared camera 14 detects a fire, the water pump 24 draws water from the water tank 22 and sprays water mist through the nozzle 21 to extinguish small fires and prevent them from spreading further.

[0029] The reciprocating mechanism includes a swing motor 25 bolted to the rear end of the fixed base 19. The rotating shaft of the swing motor 25 extends downwards and is parallel to the connecting shaft 20. A crank 26 is bolted to the rotating shaft of the swing motor 25. A sliding pin 27, parallel to the connecting shaft 20, is fixed to the bottom of the crank 26 away from the swing motor 25. A strip hole 28 matching the sliding pin 27 is provided on the horizontal part of the mounting plate 18. The length of the strip hole 28 extends along the radius of the connecting shaft 20. The sliding pin 27 is slidably installed in the strip hole 28. When the nozzle 21 sprays water mist, the swing motor 25 drives the crank 26 to rotate. The crank 26 drives the sliding pin 27 to move in a circle around the rotating shaft of the swing motor 25. In turn, the sliding pin 27 drives the mounting plate 18 and the nozzle 21 to swing back and forth, thereby increasing the spray range of the water mist from the nozzle 21 and improving the fire extinguishing efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
