As shown in
The automatic fire extinguishing device of the present invention comprises a sweeping robot 1 and a fire extinguishing mechanism 2. Under normal circumstances, the sweeping robot 1 is separated from the fire extinguishing mechanism 2. The fire extinguishing mechanism 2 is placed at a fixed position while the sweeping robot 1 is able to clean the room by sweeping the floor. When the camera 11 of the sweeping robot 1 captures a fire point, the processor will analyze the image. Once the fire point is confirmed, the sweeping robot 1 will quickly move to the position of the fire extinguishing mechanism 2 to connect the supporting base 22 and takes the fire extinguishing mechanism 2 to the fire point for fire extinguishing. It can adjust the spraying angle of the fire extinguisher 3 via the swinging mechanism according to the different position of the fire point. Meanwhile, the clamping mechanism 25 controls the control handle on the fire extinguisher 3, thus realizing the automatic fire extinguishing function. Simple in structure, and safe and reliable in operation, the invention is able to detect fire danger timely and make response promptly, thus effectively avoiding the spread of fire. In addition, the product of the invention has various functions, takes up less space, reduces the cost and enjoys better versatility as the fire extinguisher 3 can be easily replaced.
In the technical embodiment of the present invention, said swinging mechanism comprises two supporting plates, a supporting base 22, two swinging arms, at least one swinging motor for driving the swinging arms to swing, and a retaining ring 23 for fixing the fire extinguisher, wherein said two supporting plates are disposed symmetrically on two sides of the upper end of the supporting platform 21, and the upper ends of said two supporting plates are respectively provided with a horizontal supporting portion 24. Said swinging motor is disposed in said supporting portion 24. The upper ends of said two swinging arms are respectively hinged with said two supporting portions 24 while the lower ends of said two swinging arms are respectively connected to the two ends of said supporting base 22. Said retaining ring 23 is disposed between the upper ends of the two swinging arms. The pitch angle of the two swinging arms can be adjusted via the swinging motor so as to adjust the spraying angle of the fire extinguisher 3, thus extinguishing fires of different heights effectively.
