[0034] Combination Figures 1 to 3 As shown, the rotating plate 13 is made of metal material, and two push rods are arranged on the rotating plate 13, including a first push rod 141 located at a lower relative position and a second push rod 142 located at an upper relative position. Figure 6 As shown, two push rods are arranged at intervals on the upper and lower sides of the opening plate 21 of the dry powder tank 2, the first push rod 141 is located below the opening plate 21, and the second push rod 142 is located above the opening plate 21, and the arrangement directions of the first push rod 141 and the second push rod 142 are perpendicular to the arrangement direction of the opening plate 21 of the dry powder tank 2. The driving motor 11 drives the rotating plate 13 to rotate counterclockwise, and the first push rod 141 fixedly arranged on the rotating plate 13 pushes the opening plate 21 of the dry powder tank 2 to rotate counterclockwise, and the dry powder tank 2 sprays dry powder to perform firefighting operations. The driving motor 11 drives the rotating plate 13 to rotate clockwise, and the second push rod 142 fixedly arranged on the rotating plate 13 pushes the opening plate 21 of the dry powder tank 2 to rotate clockwise, and finally the shutdown is achieved, and the dry powder tank 2 stops spraying dry powder.

[0035] Combination Figures 3 to 6As shown, a first induction switch 151 and a second induction switch 152 are also provided on the other side of the central main board 1. The first induction switch 151 and the second induction switch 152 are both provided with induction probes, which can sense and detect metal objects. When the induction probe senses and detects that the rotating plate 13 passes by, it will transmit a signal to cut off the power and shut down the drive motor 11. The first induction switch 151 is arranged below the bearing seat 12, and the second induction switch 152 is arranged in the horizontal direction of the bearing seat 12 and is located obliquely above the first induction switch 151. The control ends of the first induction switch 151 and the second induction switch 152 are connected to the control end of the drive motor 11 through a signal cable. When the output shaft of the drive motor 11 drives the rotating plate 13 to rotate counterclockwise, the first push rod 141 on the rotating plate 13 pushes the opening plate 21 of the dry powder tank 2 counterclockwise until the induction probe on the second induction switch 152 detects the rotating plate 13, the drive motor 11 stops working, the rotating plate 13 stops rotating, the opening plate 21 stops rotating, and the dry powder tank 2 performs the spraying operation. When the output shaft of the driving motor 11 drives the rotating plate 13 to rotate clockwise, the second push rod 142 on the rotating plate 13 pushes the opening plate 21 of the dry powder tank 2 clockwise until the induction probe of the first induction switch 151 detects the rotating plate 13, the driving motor 11 stops working, the rotating plate 13 stops rotating, the opening plate 21 stops rotating, and the dry powder tank 2 stops spraying. By setting the first induction switch 151 and the second induction switch 152, the working range can be controlled to avoid exceeding the action range of the opening rod 21 of the dry powder tank 2.
