Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting sprinkler head with an alarm function. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire. There are drooping sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, side wall sprinkler heads, etc. In general, fire sprinkler heads are installed on walls or ceilings and connected to pressurized water network pipes, or individual sprinkler heads are installed along the pipes to protect the area below them. Existing fire sprinkler heads are often used in conjunction with smoke alarms during use. When a fire occurs, the thick smoke generated will enter the smoke alarm from the smoke inlet of the smoke alarm. The smoke particles in the smoke will enter the internal sensor of the smoke alarm and disrupt the current, causing the alarm to sound, causing the solenoid valve on the fire sprinkler head to open, so that the fire sprinkler head sprays water to extinguish the fire.

[0003] However, after the smoke alarm on the fire sprinkler head has been installed for a long time, dust in the air tends to accumulate in large quantities on the smoke inlet, which can easily cause the smoke inlet to be blocked. As a result, the thick smoke generated by the fire cannot enter the smoke alarm, causing the smoke alarm to malfunction and be unable to sound an alarm. Therefore, the utility model provides a fire sprinkler head with an alarm function. Utility Model Content

[0019] Reference Figure 1-3A fire sprinkler head with an alarm function comprises a fire sprinkler head pipe body 1, a mounting thread 2 is arranged on the surface of the fire sprinkler head pipe body 1, a solenoid valve 3 is arranged on the fire sprinkler head pipe body 1, a mounting plate 4 is fixedly installed on the surface of the fire sprinkler head pipe body 1, a smoke alarm 5 is fixedly installed at the bottom of the mounting plate 4, a smoke inlet groove 6 is provided at the bottom of the smoke alarm 5, a driving assembly is arranged at the bottom of the mounting plate 4, a movable plate 9 is arranged at the bottom of the mounting plate 4 through the driving assembly, the driving assembly comprises a driving motor 14 arranged at the bottom of the mounting plate 4, a rotating shaft 15 is fixedly installed at the output end of the driving motor 14, a rotating disk 16 is fixedly installed at the bottom of the rotating shaft 15, a fixing column 17 is fixedly installed at the bottom of the rotating disk 16, a movable plate 12 is overlapped at the bottom of the rotating disk 16, and the top of the movable plate 12 A slide groove 13 is provided throughout, and a fixed column 17 is slidably connected to the slide groove 13. A connecting rod 11 is fixedly installed on the front side of the movable plate 12. The connecting rod 11 is a rectangular structure. The connecting rod 11 is made of stainless steel. The connecting rod 11 is located below the turntable 16, which is convenient for the connecting rod 11 to have a higher structural strength, so that the connecting rod 11 is not easy to bend, and the connecting rod 11 is prevented from completely causing the movable plate 9 to be unable to move, and the movable plate 9 is prevented from being unable to drive the brush 10 to clean the smoke inlet groove 6 at the bottom of the smoke alarm 5. The connecting rod 11 is fixedly connected to the movable plate 9, and the rotating shaft 15 and the turntable 16 are rotated by the driving motor 14, so that the fixed column 17 rotates with the turntable 16, which will make the fixed column 17 The movable plate 12 is pushed forward and backward by sliding relatively left and right along the slide groove 13, driving the connecting rod 11 to move forward and backward, driving the movable plate 9 to move forward and backward, so as to provide driving force for the forward and backward movement of the movable plate 9, so as to facilitate the brush 10 to clean the dust on the smoke inlet groove 6. The brush 10 is fixedly installed on the top of the movable plate 9, and a guide assembly is arranged inside the movable plate 9, and the guide assembly is connected to the bottom of the mounting plate 4. The guide assembly includes a guide rod 8 arranged inside the movable plate 9, and the guide rod 8 is slidably connected to the movable plate 9. There are multiple guide rods 8, and the multiple guide rods 8 are symmetrically distributed, and the guide rods 8 are cylindrical in structure. A fixed plate 7 is fixedly installed on the surface of the guide rod 8, and the fixed plate 7 is fixed to the mounting plate 4 The movable plate 9 can be limited and guided by the guide rod 8, so that the movable plate 9 can only move in the direction guided by the guide rod 8, thereby ensuring that the movable plate 9 can drive the brush 10 to clean the smoke inlet slot 6, and avoiding the movable plate 9 driving the movable plate 12 to fall through the connecting rod 11, thereby ensuring that the fixed column 17 can always be located inside the slide slot 13, thereby ensuring that the brush 10 can clean the smoke inlet slot 6 at the bottom of the smoke alarm 5. A water splashing component is provided at the bottom of the fire sprinkler pipe body 1. The fire sprinkler head with an alarm function can make the movable plate 9 move forward and backward along the guide component through the driving component, driving the brush 10 to move forward and backward, so as to clean the dust on the smoke inlet slot 6.This avoids the phenomenon that dust in the air easily blocks the smoke inlet slot 6, thereby ensuring that the smoke alarm 5 can detect smoke normally, so that the fire sprinkler head sprays water to extinguish the fire in case of fire.

[0020] according to Figure 1 As shown, the splashing assembly includes a mounting column 18 arranged at the bottom of the fire sprinkler pipe body 1, and a splashing plate 19 is fixedly installed at the bottom of the mounting column 18. There are multiple mounting columns 18, and the multiple mounting columns 18 are symmetrically distributed, and the mounting columns 18 are in an arc-shaped structure. The water sprayed from the bottom of the fire sprinkler pipe body 1 will fall on the splashing plate 19, so that the water can fall from the surrounding of the splashing plate 19 in a dispersed manner, thereby facilitating the expansion of the water spraying range, so that the fire can be better extinguished.

[0021] The fire sprinkler head with alarm function is connected to 220V mains electricity, and the main controller can be a conventional known device for control such as a computer.

[0022] When in use: the fire sprinkler pipe body 1 is installed on the water network pipe full of pressure through the installation thread 2. After a long time of installation, the driving motor 14 is started to rotate the rotating shaft 15, the rotating disk 16 is rotated, and the fixed column 17 is rotated with the rotating disk 16. During the rotation of the fixed column 17, the fixed column 17 will slide relatively left and right along the slide groove 13, so that the movable plate 12 is pushed to move forward and backward, the connecting rod 11 is driven to move forward and backward, the movable plate 9 is driven to move forward and backward along the guide rod 8, and the brush 10 is driven to move forward and backward. The smoke inlet groove 6 is wiped by the forward and backward movement of the brush 10. When a fire occurs, the generated thick smoke will enter the smoke alarm 5 from the smoke inlet groove 6. After the smoke alarm 5 detects a certain concentration of smoke, an alarm sound will be sounded. At the same time, the solenoid valve 3 is opened, and water will be sprayed from the bottom of the fire sprinkler pipe body 1 and fall on the splash plate 19. The water is dispersed and falls through the splash plate 19 to extinguish the fire.
