Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler head technology, and in particular to an anti-clogging structure for fire sprinkler heads. Background Technology

[0002] Fire sprinkler heads are fire extinguishing devices and an important component of automatic sprinkler systems. When a fire occurs, the sprinkler head automatically senses temperature changes at the fire scene. When the temperature reaches a certain value, the sprinkler head opens, spraying water evenly over a specific area to extinguish, control, and cool the area, effectively controlling the spread of fire, buying time for evacuation and rescue, and reducing fire damage. The anti-clogging structure of a fire sprinkler head refers to a device installed in the sprinkler head to prevent impurities and foreign objects in the water from entering the nozzles, thus preventing clogging and ensuring the sprinkler head can spray water normally to extinguish the fire.

[0003] Current fire sprinkler heads work by installing a filter screen at the water inlet to intercept impurities and particulate solids in the water, preventing them from entering the sprinkler head and clogging the spray nozzles. However, the mesh of the filter screen can become clogged after filtering impurities for a long time. Once the filter screen is clogged, it not only affects the normal spraying of the sprinkler head but also causes pressure imbalance in the entire sprinkler system, thus affecting the subsequent use of the sprinkler head. Existing technology incorporates a multi-stage filtration structure inside the sprinkler head and in the piping system. Different stages of the filter screen have different pore sizes and filtration precision, gradually filtering impurities in the water from coarse to fine. However, although the filter screen can filter impurities, over time, impurities will gradually adhere to the inner wall of the sprinkler head pipes, leading to blockage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-clogging structure for fire sprinkler heads, aiming to improve the problem in the prior art where impurities gradually adhere to the inner wall of the sprinkler head pipe over a long period of time, thus causing blockage.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fire sprinkler head anti-clogging structure, including a sprinkler head, a support frame fixedly connected to the inner wall of the sprinkler head, a fixed short column rotatably connected to the bottom of the support frame, multiple fixed short plates I fixedly connected at equal intervals to the outer wall of the fixed short column, scrapers fixedly connected to the outer wall of each fixed short plate I on the side away from the outer wall, multiple fixed short plates II fixedly connected at equal intervals to the outer wall of the fixed short column, brushes fixedly connected to the outer wall of each fixed short plate II on the side away from the outer wall, a bidirectional turbine fixedly connected to the bottom end of the fixed short column, a threaded column fixedly connected to the bottom end of the bidirectional turbine, a connecting pipe installed on the top of the sprinkler head, and a reinforcing mechanism installed on the right side of the outer wall of the sprinkler head, the reinforcing mechanism being used to reinforce the connection between the connecting pipe and the sprinkler head.

[0006] As a further description of the above technical solution:

[0007] The reinforcement mechanism includes a hollow short block one, which is installed on the right side of the outer wall of the nozzle. A bidirectional threaded rod is rotatably connected to the middle of the hollow short block one. A worm gear is fixedly connected to the middle of the outer wall of the bidirectional threaded rod. A worm is rotatably connected inside the hollow short block one, and the worm gear meshes with the worm gear. Inner sliding guide plates are fixedly connected to the upper and lower sides of the outer wall of the hollow short block one. Multiple double-sided sawtooth blocks are equidistantly threaded to the outer wall of the bidirectional threaded rod. A hollow short block two is fixedly connected to the right side of the outer wall of the nozzle and the connecting pipe. Spring rods are installed on the front and rear sides of the inner wall of the hollow short block two. A concave tooth plate is fixedly connected to an adjacent end of the outer wall of the spring rod.

[0008] As a further description of the above technical solution:

[0009] A sealing sleeve is fixedly connected to the top of the nozzle.

[0010] As a further description of the above technical solution:

[0011] Each of the outer walls of the spring rod is threaded with a screw three at the end furthest from the other end, and the outer wall of the screw three is threaded with an anti-slip sleeve.

[0012] As a further description of the above technical solution:

[0013] A circular throttle is fixedly connected to the front end of the outer wall of the worm gear.

[0014] As a further description of the above technical solution:

[0015] A protective sleeve is fixedly connected to the outer wall of the circular throttle.

[0016] As a further description of the above technical solution:

[0017] A screw is threadedly connected to the front side of the outer wall of the nozzle, and a warning sign is threadedly connected to the outer wall of the screw.

[0018] As a further description of the above technical solution:

[0019] The nozzle has two screws threadedly connected to the front and rear sides of its outer wall, and a reflective strip is threadedly connected to the outer wall of the screw.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the bidirectional turbine is driven to rotate by the impact of water flow, which in turn drives the fixed short column to rotate. When the fixed short column rotates, the scraper on the outer wall scrapes away impurities from the inner wall of the nozzle, and the brush cleans away fine dirt to ensure cleanliness. The bidirectional turbine accelerates the water flow through the groove of the threaded column, guiding and accelerating the water flow to flush the inside of the nozzle at high speed, preventing impurities from accumulating and clogging. This avoids the problem that impurities will gradually adhere to the inner wall of the nozzle pipe after a long period of time, thus causing blockage.

[0022] 2. In this utility model, by rotating the worm gear and meshing with the worm wheel, the worm wheel and the double-sided threaded rod are driven to rotate. The double-sided sawtooth block on the double-sided threaded rod moves accordingly. Then, the spring rod is pulled to retract the concave tooth plate. When the sawtooth block reaches the appropriate position, the spring rod is released, and the concave tooth plate and the sawtooth are engaged, reinforcing the connection and preventing the connection from loosening due to water flow impact or other factors during use. This ensures a stable connection between the connecting pipe and the sprinkler head and guarantees the normal operation of the fire sprinkler system. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a fire sprinkler head anti-clogging structure, including a sprinkler head 1. A support frame 16 is fixedly connected to the inner wall of the sprinkler head 1. A fixed short column 17 is rotatably connected to the bottom of the support frame 16. Multiple fixed short plates 12 are fixedly connected at equal intervals to the outer wall of the fixed short column 17. Scrapers 18 are fixedly connected to the outer wall of each fixed short plate 12 on the side furthest away from it. Multiple fixed short plates 13 are fixedly connected at equal intervals to the outer wall of the fixed short column 17. Brushes 14 are fixedly connected to the outer wall of each fixed short plate 13 on the side furthest away from it. A bidirectional turbine 15 is fixedly connected to the bottom end of the fixed short column 17. A threaded post 19 is fixedly connected to the bottom of the turbine 15. A connecting pipe 7 is installed on the top of the nozzle 1. A reinforcing mechanism 2 is installed on the right side of the outer wall of the nozzle 1. The reinforcing mechanism 2 is used to reinforce the connection between the connecting pipe 7 and the nozzle 1. A sealing sleeve 20 is fixedly connected to the top of the nozzle 1. The sealing sleeve 20 enhances the sealing of the connection between the connecting pipe 7 and the nozzle 1. A screw 11 is threadedly connected to the outer wall of the spring pull rod 203 at the far end. An anti-slip sleeve 8 is threadedly connected to the outer wall of the screw 11. The anti-slip sleeve 8 can prevent the operator from slipping when pulling the spring pull rod 203.

[0033] Specifically, when water flows through the nozzle 1, it impacts the bidirectional turbine 15 at the bottom of the fixed short column 17, causing the turbine 15 to rotate. The rotation of the turbine 15 drives the fixed short column 17 to rotate. As the fixed short column 17 rotates, the fixed short plates 12 and 13 fixed to its outer wall also rotate. During rotation, the scraper 18 on the fixed short plate 12 contacts the inner wall of the nozzle 1, scraping away impurities adhering to the inner wall and preventing them from accumulating and clogging the surface. The brush 14 on the fixed short plate 13 further cleans the inner wall of the nozzle 1 of fine impurities and dirt, ensuring its cleanliness. Finally, the water flows through the bidirectional turbine 15. The high-speed water flow passes through the grooves on the outer wall of the threaded column 19. These grooves guide and accelerate the water flow, giving it a higher speed. This high-speed water flow can flush away impurities remaining inside the nozzle 1, removing scraped and cleaned impurities in a timely manner and preventing them from accumulating and clogging the nozzle 1. A sealing sleeve 20 is fixedly connected to the top of the nozzle 1. The sealing sleeve 20 enhances the sealing at the connection between the connecting pipe 7 and the nozzle 1. Screws 11 are threadedly connected to the outer wall of the spring lever 203 at the opposite end. Anti-slip sleeves 8 are threadedly connected to the outer wall of screws 11. These anti-slip sleeves 8 prevent the operator from slipping when pulling the spring lever 203.

[0034] Reference Figure 3 and Figure 6 The reinforcement mechanism 2 includes a hollow short block 201, which is installed on the right side of the outer wall of the nozzle 1. A bidirectional threaded rod 202 is rotatably connected to the middle of the hollow short block 201. A worm gear 206 is fixedly connected to the middle of the outer wall of the bidirectional threaded rod 202. A worm 207 is rotatably connected inside the hollow short block 201, and the worm 207 meshes with the worm gear 206. Inner sliding guide plates 209 are fixedly connected to both the upper and lower sides of the outer wall of the hollow short block 201. Multiple double-sided sawtooth blocks 205 are equidistantly threaded onto the outer wall of the bidirectional threaded rod 202. The nozzle 1 is connected to... Hollow short blocks 204 are fixedly connected to the right side of the outer wall of pipe 7. Spring rods 203 are installed on the front and rear sides of the inner wall of hollow short blocks 204. A toothed plate 208 is fixedly connected to one adjacent end of the outer wall of spring rods 203. A circular handle 10 is fixedly connected to the front end of the outer wall of worm gear 207. The circular handle 10 can facilitate the operator to rotate worm gear 207 for use. A protective sleeve 9 is fixedly connected to the outer wall of the circular handle 10. The protective sleeve 9 can protect the circular handle 10 and prevent it from being damaged after long-term use.

[0035] Specifically, by rotating the worm 207, which is meshed with the worm wheel 206, the rotation of the worm 207 will drive the worm wheel 206 to rotate. The worm wheel 206 is fixed to the middle of the outer wall of the double-sided threaded rod 202, so the rotation of the worm wheel 206 will cause the double-sided threaded rod 202 to rotate. When the double-sided threaded rod 202 rotates, the double-sided sawtooth block 205 on the outer wall will move along the double-sided threaded rod 202, which will then pull the spring rod 203, causing the concave tooth plate 208 to retract. Then, when the double-sided sawtooth block 205... 5. After moving to the appropriate position, release the pulled spring rod 203 to make the concave tooth plate 208 engage with the serrations on the outer wall of the double-sided serrated block 205 to reinforce the connection. A circular handle 10 is fixedly connected to the front end of the outer wall of the worm 207. The circular handle 10 can facilitate the operator to rotate the worm 207 for use. A protective sleeve 9 is fixedly connected to the outer wall of the circular handle 10. The protective sleeve 9 can protect the circular handle 10 and prevent it from being damaged after long-term use.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the nozzle 1 is threaded with screw 3. The outer wall of screw 3 is threaded with a warning sign 4. The warning sign 4 can remind the staff of the precautions when operating the nozzle 1. The outer wall of the nozzle 1 is threaded with screw 5. The outer wall of screw 5 is threaded with reflective strip 6. The reflective strip 6 can reflect the surrounding light in a well-lit environment, thereby serving as a warning and reminder to the surroundings.

[0037] Specifically, screw 3 is threaded on the front side of the outer wall of nozzle 1, and warning sign 4 is threaded on the outer wall of screw 3. Warning sign 4 can remind staff of precautions when operating nozzle 1. Screw 5 is threaded on the front and rear sides of the outer wall of nozzle 1, and reflective strip 6 is threaded on the outer wall of screw 5. Reflective strip 6 can reflect the surrounding light in a well-lit environment, thereby serving as a warning and reminder to the surroundings.

[0038] Working principle: When water flows through the nozzle 1, it impacts the bidirectional turbine 15 at the bottom of the fixed short column 17, causing the turbine 15 to rotate. The rotation of the turbine 15 drives the fixed short column 17 to rotate. As the fixed short column 17 rotates, the fixed short plates 12 and 13 fixed to its outer wall also rotate. During rotation, the scraper 18 on the fixed short plate 12 contacts the inner wall of the nozzle 1, scraping away impurities adhering to the inner wall and preventing them from accumulating and clogging the surface. The brush 14 on the fixed short plate 13 further... The inner wall of the nozzle 1 is cleaned to remove fine impurities and dirt, ensuring its cleanliness. Finally, the water flow accelerated by the rotation of the bidirectional turbine 15 passes through the groove on the outer wall of the threaded column 19. The groove on the outer wall of the threaded column 19 guides and accelerates the water flow, giving it a higher speed. The high-speed water flow can flush away the impurities remaining inside the nozzle 1, removing the scraped and cleaned impurities in time, preventing impurities from accumulating inside the nozzle 1 and causing blockage. This avoids the problem of impurities gradually adhering to the inner wall of the nozzle 1 pipe over a long period of time, thus preventing blockage.

[0039] By rotating the worm 207, which meshes with the worm wheel 206, the rotation of the worm 207 will drive the worm wheel 206 to rotate. The worm wheel 206 is fixed in the middle of the outer wall of the double-sided threaded rod 202, so the rotation of the worm wheel 206 will cause the double-sided threaded rod 202 to rotate. When the double-sided threaded rod 202 rotates, the double-sided sawtooth block 205 on the outer wall will move along the double-sided threaded rod 202, and then pull the spring rod 203, causing the concave tooth plate 208 to retract. Then, when the double-sided sawtooth block 205 moves to the appropriate position, the pulled spring rod 203 is released, so that the concave tooth plate 208 and the sawtooth on the outer wall of the double-sided sawtooth block 205 are engaged to strengthen the connection, prevent the connection from loosening due to water flow impact and other factors during use, ensure the connection between the connecting pipe 7 and the sprinkler head 1 is stable, and ensure the normal operation of the fire sprinkler system.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
