Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a drainage control structure for a fire sprinkler head. Background Technology

[0002] Fire sprinkler heads are used in fire sprinkler systems. They are triggered by temperature or smoke. In open fire sprinkler systems, smoke detectors are installed to detect smoke. When the smoke reaches a certain concentration, the smoke detectors alarm. After confirmation by the main unit, the alarm is triggered by sound or flashing lights. The alarm also activates the smoke exhaust fan to start exhausting the smoke. At the same time, the solenoid valve of the deluge valve is opened, which activates the sprinkler pump, and the open sprinkler heads spray water directly.

[0003] Existing fire sprinkler heads are usually installed directly at the end of fire hydrants at a fixed angle. They spray water evenly around the fire by spraying water from a sprinkler disc, which cannot accurately extinguish the fire source. This results in a large amount of water being consumed during firefighting, leading to water waste and low firefighting efficiency.

[0004] Therefore, it is necessary to invent a fire sprinkler head drainage control structure to solve the above problems. Utility Model Content

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model provides, for example Figures 1 to 4The fire sprinkler head drainage control structure shown includes a mounting plate 1, a connector 2 on the lower side of the mounting plate 1, and a mounting frame 4 on the upper side of the mounting plate 1. A control component is arranged between the mounting plate 1, the connector 2, and the mounting frame 4. The control component includes a connecting shaft 11, an infrared sensor 12, a connecting frame 13, a first motor 14, a connecting block 21, a transmission shaft 22, a mounting base 41, a connecting groove 42, and a second motor 43. A sprinkler pipe 3 is connected to the lower side of the connector 2, and a water inlet hose 23 is fixedly connected to the side of the connector 2. A threaded hole is opened at the lower end of the connector 2. A threaded tooth 34 is provided on the side of the sprinkler pipe 3 near the upper end. The upper end of the sprinkler pipe 3 is threadedly connected to the threaded hole through the threaded tooth 34. A sprinkler head 31 is fixedly connected to the lower end of the sprinkler pipe 3.

[0032] The fire sprinkler head works in conjunction with a smoke detector. The smoke detector detects smoke, and when the smoke reaches a certain concentration, it alarms. After confirmation by the main unit, the infrared sensor 12 is activated to locate the ignition point. The angle of the sprinkler head 31 is adjusted by the control component to align it with the ignition point. At the same time, the fire solenoid valve is opened, and the sprinkler pump is activated, so that water flows through the sprinkler head 31 and sprays water onto the ignition point, enabling the fire to be quickly and accurately extinguished in its early stages.

[0033] See Figure 2 and Figure 3 The connecting shaft 11 is fixedly connected to the middle of the upper surface of the mounting plate 1. Infrared sensors 12 are fixedly connected to both the front and rear sides of the mounting plate 1. The connecting frame 13 is fixedly connected to the lower surface of the mounting plate 1. The first motor 14 is fixedly installed on the rear side of the connecting frame 13. The mounting base 41 is fixedly connected to the lower end of the mounting frame 4.

The connecting block 21 is fixedly connected to the upper end of the connecting head 2. The front and rear ends of the connecting block 21 are fixedly connected to the transmission shaft 22. The two sets of transmission shafts 22 are rotatably connected to the inner walls of the front and rear sides of the connecting frame 13 respectively. The output end of the first motor 14 is fixedly connected to the rear transmission shaft 22.

[0034] Specifically, after the two sets of infrared sensors 12 work together to locate the ignition point, they transmit the information to the host. Upon receiving the information, the host starts the two sets of motors. At this time, the output end of the first motor 14 drives the transmission shaft 22 to rotate, which in turn drives the connecting block 21 and the connector 2 to rotate, thereby driving the spray pipe 3 to rotate and adjusting the vertical angle of the spray pipe 3. At the same time, the output end of the second motor 43 drives the connecting shaft 11 to rotate, which in turn drives the mounting plate 1 to rotate and adjusts the horizontal angle of the connector 2, thereby adjusting the horizontal angle of the spray pipe 3, so that the spray head 31 is aimed at the ignition point, thereby accurately extinguishing the fire source.

[0035] See Figure 4 and Figure 5 A drain pipe 32 is fixedly connected to the side of the spray pipe 3. A drain valve 33 is provided on the surface of the drain pipe 32. A filter screen 35 is snapped into the inside of the spray pipe 3. Multiple sets of support rods 36 are fixedly connected to the upper surface of the filter screen 35. The upper end of the support rods 36 is snapped into the upper edge of the spray pipe 3.

[0036] In addition, during use, the water is filtered through the filter screen 35 to prevent impurities in the water from clogging the spray holes in the sprinkler head 31, thereby improving the safety of the sprinkler head. At the same time, the drain valve 33 can be opened to flush and clean the impurities accumulated on the surface of the filter screen 35 with water flow, keeping the inside of the sprinkler head unobstructed and improving fire safety.

[0037] The working principle of this utility model is as follows: By controlling and adjusting the angle of the spray head 31 through the control component, the drainage direction of the spray head 31 can be adjusted, which can accurately extinguish the fire in the early stage, effectively improve the fire extinguishing efficiency, reduce property damage and save fire extinguishing water; and the filter screen 35 is used to filter the water to prevent impurities in the water from clogging the spray holes in the spray head 31, keep the inside of the spray head unobstructed and improve fire safety.
