DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a smoke alarm for an industrial control system room, including a storage box 1, a mounting frame 2 is fixedly connected to the left side of the storage box 1, a driving mechanism 4 is arranged in the storage box 1 through the mounting frame 2, a dust blocking mechanism 3 is arranged on the right side of the storage box 1, a mounting seat 5 is arranged in the storage box 1 through the driving mechanism 4, and an alarm 6 is fixedly installed on the right side of the mounting seat 5 and is arranged in the storage box 1.

[0023] The dust shield mechanism 3 includes a connecting rod 301, which is arranged in the storage box 1, and a dust shield plate 302 is arranged on the right side of the connecting rod 301. A fixed shaft 303 is fixedly connected to the top of the front and rear sides of the dust shield plate 302, and a torsion spring 304 is sleeved on the outer side of the fixed shaft 303. A connecting plate 305 is fixedly connected to the left side of the connecting rod 301, a support plate 306 is fixedly connected to the left side of the connecting plate 305, and a first rack 307 is fixedly connected to the right side of the support plate 306. The connecting rod 301 is correspondingly provided with a limiting groove 308 matching it on the inner surface of the storage box 1. Two connecting rods 301 are provided, and the two connecting rods 301 are symmetrically arranged on the right side of the storage box 1 and are slidably arranged in the storage box 1 through the limiting groove 308 respectively. The two ends of the torsion spring 304 are respectively connected to the connecting rod 301 and the dust shield plate 302, and the dust shield plate 302 is arranged on the inner half of the storage box 1 and is arranged on the right side of the storage box 1 through the connecting rod 301.

[0024] Through the operation of the driving mechanism 4, the first rack 307 drives the support plate 306 to slide to the left in the storage box 1, thereby driving the connecting rod 301 to slide through the connecting plate 305. When the dust shield plate 302 is squeezed by the mounting seat 5, the dust shield plate 302 rotates through the fixed shaft 303 and the torsion spring 304, so that the alarm 6 protrudes from the right side of the storage box 1 to perform an alarm operation. Conversely, through the reverse rotation of the motor 401, the alarm 6 is retracted into the storage box 1 through the mounting seat 5, and the dust shield plate 302 slides to the right. Under the resetting action of the torsion spring 304, the dust shield plates 302 are closed to seal the right side of the storage box 1, thereby performing a dust-proof operation on it.

[0025] According to the above working process, it can be known that: by setting the dust shielding mechanism 3, the alarm 6 can be conveniently protected from dust, thereby improving its use effect, so as to perform accurate alarm operation.

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the driving mechanism 4 includes a motor 401, which is fixedly installed in the installation frame 2, and a threaded rod 402 is fixedly connected to the right end of the motor 401. A movable plate 403 is threadedly connected to the threaded rod 402 and is arranged in the storage box 1. A sliding rod 404 is slidably connected to the movable plate 403 and is fixedly connected to the storage box 1 through the installation frame 2. The right ends of the threaded rod 402 and the sliding rod 404 are fixedly connected to a fixed plate 405 and are fixedly installed in the storage box 1. A fixed seat 406 is fixedly connected to the front and rear sides of the fixed plate 405, and a gear 407 is rotatably connected to the fixed seat 406. A second rack 408 is meshedly arranged on the inner side of the gear 407 and fixedly installed on the mounting seat 5. The movable plate 403 is connected to the mounting seat 5, and a through-opening matching the mounting seat 5 is arranged on the fixed plate 405. The mounting seat 5 slides on the fixed plate 405 through the through-opening, and the outer side of the gear 407 is meshed with the first rack 307.

[0027] By running the motor 401, the threaded rod 402 rotates to drive the movable plate 403 to move on the threaded rod 402, and cooperates with the slide rod 404 to allow the movable plate 403 to move in the storage box 1, so that the mounting base 5 pushes the alarm 6 to slide on the right side of the storage box 1, and because the second rack 408 is engaged with the gear 407, the gear 407 rotates, and because the gear 407 is engaged with the first rack 307, the dust shielding mechanism 3 is opened, otherwise it is closed to prevent dust from occurring on the alarm 6, thereby improving the dustproof effect of the device.

[0028] This scheme has the following working process: when this device is used, the device is positioned and installed through the installation frame 2, and the alarm 6 is used to sound an alarm. When the alarm 6 sounds an alarm, the motor 401 is operated to rotate the threaded rod 402 to drive the movable plate 403 to move on the threaded rod 402, and cooperate with the slide bar 404 to allow the movable plate 403 to move in the storage box 1, so that the mounting seat 5 pushes the alarm 6 to slide on the right side of the storage box 1, and because the second rack 408 is meshed with the gear 407, the gear 407 rotates, and because the gear 407 is meshed with the first rack 307, the first rack 30 7 drives the support plate 306 to slide to the left in the storage box 1, thereby driving the connecting rod 301 to slide through the connecting plate 305. When the dust shield plate 302 is squeezed by the mounting seat 5, the dust shield plate 302 rotates through the fixed shaft 303 and the torsion spring 304, so that the alarm 6 protrudes from the right side of the storage box 1 to perform an alarm operation. Conversely, through the reverse rotation of the motor 401, the alarm 6 is retracted into the storage box 1 through the mounting seat 5, and the dust shield plate 302 slides to the right. Under the resetting action of the torsion spring 304, the dust shield plates 302 are closed to block the right side of the storage box 1, thereby performing a dust-proof operation on it.

[0029] In summary: by setting up the dust blocking mechanism 3, the alarm 6 can be conveniently protected from dust, thereby improving its use effect so as to perform accurate alarm operation; by setting up the driving mechanism 4, the alarm 6 can be turned on or off through the dust blocking mechanism 3 according to the working condition of the alarm 6, thereby further improving the dust-proof effect of the alarm 6 and facilitating use.
