DETAILED DESCRIPTION

[0020] like Figure 1-2As shown, a fire sprinkler device includes a mounting plate 1, a connecting column 2 rotatably connected to the bottom wall of the mounting plate 1, a connecting plate 3 fixedly connected to the lower end of the connecting column 2, and a sprinkler head 4 installed below the connecting plate 3, and also includes an angle adjustment component and an azimuth adjustment component. The angle adjustment component is arranged below the connecting plate 3, and the azimuth adjustment component is arranged between the mounting plate 1 and the connecting plate 3.

[0021] like Figure 1-3 As shown, in order to conveniently adjust the spray angle of the nozzle 4, the angle adjustment component includes a bottom plate 5 fixedly connected to the bottom wall of the connecting plate 3, a connecting frame 6 rotatably connected to the outer wall of the bottom plate 5, a limit frame 7 fixedly connected to both ends of the connecting frame 6, an arc plate 8 fixedly connected between the connecting frames, a rack 9 fixedly connected to the top wall of the arc plate 8, a square plate 10 fixedly connected to the bottom wall of the bottom plate 5, a stepping motor 11 fixedly installed on the outer wall of the square plate 10, a driving gear 12 fixedly connected to the output end of the stepping motor 11, a fixed plate 13 fixedly connected to the bottom wall of the connecting plate 3 and symmetrically arranged, and a cylinder 14 fixedly connected to the outer wall of the fixed plate 13, the middle position of the limit frame 7 is a through setting, one end of the cylinder 14 is set through the middle position of the limit frame 7, the driving gear 12 is meshed with the rack 9, and the nozzle 4 is fixedly installed on the bottom wall of the arc plate 8

[0022] like Figure 1-2 As shown, in order to conveniently adjust the spraying direction of the nozzle 4 and expand its spraying area, the direction adjustment component includes a servo motor 15 fixedly mounted on the bottom wall of the mounting plate 1, a bevel gear 16 fixedly connected to the output end of the servo motor 15, a bevel gear 2 17 fixedly connected to the connecting column 2, and a limit rod 18 fixedly connected to the top wall of the connecting plate 3 and symmetrically arranged. A limit groove 19 is provided on the bottom wall of the mounting plate 1, and the limit groove 19 is circularly arranged. The limit rod 18 is T-shaped, and the upper end of the limit rod 18 is arranged inside the limit groove 19, and the bevel gear 16 and the bevel gear 2 17 are meshed.
