Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler heads, in particular to an anti-clogging fire sprinkler head. Background Art

[0002] Fire sprinkler is a kind of sprinkler that starts automatically within a predetermined temperature range under the action of heat, or is started by a control device according to a fire signal, and sprays water to extinguish fire according to the designed water spraying shape and flow rate. It is a part of the sprinkler system. The water outlet of the fire sprinkler is blocked by thermosensitive glass. When the temperature rises due to indoor fire, the thermosensitive glass breaks and cannot block the water. The sprinkler can then spray water to extinguish the fire.

[0003] The nozzles of fire sprinkler heads are usually tiny, and if the fire sprinkler heads are not used for a long time, the water in the pipes and nozzles will precipitate. Since the water used in fire sprinkler heads usually contains impurities, long-term precipitation will cause the impurities to clog the fire sprinkler heads, resulting in the fire sprinkler heads being unable to spray water in time to extinguish fires when used, greatly affecting fire safety.

The second support rod 14 is driven to rotate by the driven gear 13. The first support rod 9 is provided with a second support rod 14 through a connecting assembly. The second support rod 14 is rotatably connected to the housing 1. The first support rod 9 and the second support rod 14 can be driven to rotate by a motor, so that the filter 10 and the cleaning brush 15 can be operated by a driving element. The cleaning brush 15 is fixedly provided on the surface of the second support rod 14. The cleaning brush 15 and the filter 10 The tops are overlapped, the number of cleaning brushes 15 is multiple, and the multiple cleaning brushes 15 are distributed in a circular array. The multiple cleaning brushes 15 can frequently clean the filter 10 to improve the cleaning strength of impurities. A cleaning component is arranged inside the shell 1, and the cleaning component includes an obstruction frame 16 fixedly arranged on the top of the inside of the shell 1, the bottom of the obstruction frame 16 overlaps with the top of the filter 10, and a moving block 17 is slidingly arranged inside the obstruction frame 16.

The pull block 19 is pulled to move outward, and the movement of the pull block 19 drives the pull rod 18 moves, and the movement of the pull rod 18 drives the moving block 17 to move. The moving block 17 pushes the impurities blocked by the obstruction frame 16 out of the shell 1, so as to avoid excessive impurities staying in the shell 1. A water inlet pipe 2 is fixedly arranged on the top of the shell 1. The water inlet end of the water inlet pipe 2 penetrates the shell 1 and extends to the inside of the shell 1 and overlaps with the top of the filter screen 10. A water outlet pipe 3 is fixedly arranged on the bottom of the shell 1. A water outlet assembly is arranged at the bottom of the water outlet pipe 3. When the anti-clogging fire sprinkler head is used, the rotating motor 8 is started to drive the first support rod 9 to rotate, and the first support rod 9 rotates the filter screen 10 to rotate, so that the water input by the water inlet pipe 2 falls into different positions of the filter screen 10. At the same time, the first support rod 9 rotates to drive the second support rod 14 to rotate through the connecting assembly.The second support rod 14 drives the cleaning brush 15 to rotate and clean the impurities on the top of the filter 10. The device prevents impurities from clogging the fire sprinkler head through the filter 10, and prevents impurities from accumulating on the surface of the filter 10. At the same time, the impurities on the surface of the filter 10 are cleaned, solving the problem of impurities clogging the filter holes and improving the safety of the fire sprinkler head.

[0023] Specifically, the water outlet component includes a sprinkler head 4 fixedly arranged at the water outlet end of the water outlet pipe 3. The water outlet of the sprinkler head 4 is provided with a thermosensitive glass mechanism 5. When the thermosensitive glass encounters high temperature, the glass will break. When a fire occurs indoors, the internal temperature will rise. When the breaking threshold of the thermosensitive glass mechanism 5 is reached, the glass will break, and the internal water pressure will rush out of the sprinkler head 4.

[0024] Specifically, a visual window 6 is fixedly provided inside the shell 1, and the visual window 6 is made of transparent glass. Through the visual window 6 made of transparent glass, the situation inside the shell 1 can be directly understood during maintenance, which is convenient for maintenance of the fire sprinkler head.

[0025] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0026] When in use: the glass of the thermosensitive glass mechanism 5 is broken after sensing the high temperature in the room, the water is sprayed out through the sprinkler head 4, the water inlet pipe 2 transports the water to the inside of the housing 1 and filters the impurities in the water through the filter screen 10, the filtered water is transported to the sprinkler head 4 through the water outlet pipe 3, and the rotating motor 8 is started at the same time to drive the first support rod 9 to rotate, the first support rod 9 rotates the filter screen 10 to rotate, so that the water input by the water inlet pipe 2 falls into different positions of the filter screen 10, the first support rod 9 rotates to drive the driving gear 11 to rotate, and the driving gear 1 1 rotates through the transmission chain 12 to drive the driven gear 13 to rotate, the driven gear 13 rotates to drive the second support rod 14 to rotate, the second support rod 14 drives the cleaning brush 15 to rotate to clean the surface of the filter 10, and clean the impurities in the through holes of the filter 10. After cleaning, the impurities on the surface of the filter 10 rotate with the filter 10 and are blocked by the blocking frame 16. The impurities are accumulated inside the blocking frame 16. Afterwards, the pull block 19 can be pulled, and the pull block 19 drives the moving block 17 to move through the pull rod 18 to discharge the impurities out of the housing 1.

[0027] To sum up, when the anti-clogging fire sprinkler head is in use, the rotating motor 8 is started to drive the first support rod 9 to rotate, and the first support rod 9 rotates the filter screen 10, so that the water input by the water inlet pipe 2 falls into different positions of the filter screen 10, and at the same time, the first support rod 9 rotates to drive the second support rod 14 to rotate through the connecting assembly, and the second support rod 14 drives the cleaning brush 15 to rotate to clean the surface of the filter screen 10, and cleans the impurities in the through holes of the filter screen 10.
