Description

Technical Field

[0001] The present application relates to the technical field of fire-fighting equipment, and in particular to a sprinkler for fire-fighting purposes. Background Art

[0002] A fire sprinkler, also known as a sprinkler head in an automatic sprinkler system, is an automatic fire-fighting device used to automatically spray water to extinguish fires when a fire occurs. Its concept is based on using a heat-sensitive element (such as a glass bulb or fusible alloy) to trigger the opening of the sprinkler head when a preset temperature is reached, thereby releasing water flow to control and extinguish the fire.

[0003] In the related art, reference can be made to the Chinese utility model patent with the authorization publication number CN210125121U, which discloses an automatically rotating fire sprinkler. The technical key points include a tubular water joint, a bottom plate, a water delivery pipe, and a splash plate. One end of the water joint is connected to the water pipe inside the roof, and the end of the water joint away from the roof is sequentially and mutually communicated with the bottom plate, the water delivery pipe, and the splash plate. A tee structure is formed between the water joint and the bottom plate. The water delivery pipes are evenly spaced on the circumferential surface of the bottom plate and are mutually communicated at the lower ends. The splash plate is a hollow disc-shaped structure, and a circle of sprinkler nozzles is evenly spaced on the outer circumference of the splash plate. The setting direction of the sprinkler nozzles is inclined to the circumferential tangent direction of the splash plate. The fire sprinkler includes a quick water joint, and the lower end of the converging part of the water delivery pipes is communicated with the splash plate through the quick water joint.

[0004] In actual production work, the storey heights of different buildings are different, and the length of the above-mentioned fire sprinkler is fixed. Therefore, the fire extinguishing effect of the fire sprinkler in buildings with different storey heights is also different. When facing a space with a relatively high storey height, the amount of water and water power sprayed by the fire sprinkler on the ground are weak; when facing a space with a relatively low storey height, the sprinkling area of the fire sprinkler is small. In summary, the above-mentioned fire sprinkler has poor adaptability to buildings with different storey heights. Utility Model Content

[0005] In order to improve the adaptability range of the fire sprinkler to buildings with different storey heights, the present application provides a sprinkler for fire-fighting purposes.

[0006] A sprinkler for fire-fighting purposes provided by the present application adopts the following technical solution:

[0007] A sprinkler for fire-fighting purposes includes a water connection pipe and a water outlet plate rotatably arranged on the water connection pipe. The water connection pipe is communicated with the water pipe on the roof. After the water connection pipe is filled with water, the water is conducted to the water outlet plate. A number of nozzles are evenly distributed on the circumferential side of the water outlet plate. A telescopic mechanism is arranged on the water connection pipe. The water outlet plate is connected to the water connection pipe through the telescopic mechanism. The telescopic mechanism adjusts the distance between the water outlet plate and the water connection pipe. The telescopic mechanism includes:

[0008] A telescopic pipe sleeve, which is vertically slidably arranged on the water connection pipe;

[0009] A water pipe is vertically slidably arranged on the telescopic pipe sleeve, and the water outlet tray is arranged at the bottom end of the water pipe and is communicated with the inside of the water pipe;

[0010] A first positioning component is arranged on the telescopic pipe sleeve and is used to fix the position of the telescopic pipe sleeve on the water connection pipe;

[0011] A second positioning component is arranged on the water pipe and is used to fix the position of the water pipe on the telescopic pipe sleeve.

[0012] By adopting the above technical solution, the telescopic pipe sleeve is vertically sleeved on the water collecting pipe, and then the water pipe connected to the water outlet tray is vertically slidably installed on the telescopic pipe sleeve. When installing the nozzle, according to the storey height of the on-site building, the position of the telescopic pipe sleeve on the water connection pipe can be adjusted by unlocking the first positioning component first, so as to adjust the height of the water outlet tray. When the height of the adjusted water outlet tray reaches the target position, the first positioning component is locked; when the adjusted height has not reached the target position, the second positioning component is unlocked to adjust the position of the water pipe on the telescopic pipe sleeve, so as to perform secondary adjustment on the height of the water outlet tray, so that the position of the water outlet tray can be adapted to the storey height of the building. By using the two height adjustment operations of the telescopic pipe sleeve and the water pipe, the adaptability of the water outlet position of the water outlet tray to buildings with different storey heights is improved.

[0013] Optionally, the first positioning component includes:

[0014] A first positioning plate is rotatably arranged at the top end of the telescopic pipe sleeve. There are a plurality of the first positioning plates, and the plurality of the first positioning plates are evenly arranged along the outer side wall of the top end of the telescopic pipe sleeve;

[0015] A positioning sleeve is vertically slidably sleeved on the telescopic pipe sleeve;

[0016] A driving member is arranged on the telescopic pipe sleeve and is used to drive the positioning sleeve to move. When the positioning sleeve moves to the highest position under the action of the driving member, the positioning sleeve is sleeved on the outer side walls of the plurality of first positioning plates, and the plurality of first positioning plates cooperate to tightly press against the outer side wall of the water connection pipe.

[0017] By adopting the above technical solution, the driving member is used to drive the positioning sleeve to move downward. The positioning sleeve moves downward and disengages from the first positioning plate. After the first positioning plate loses the acting force of the positioning sleeve, it no longer presses against the outer wall of the water connection pipe. Then, the telescopic pipe sleeve can be moved to adjust the position of the telescopic pipe sleeve. After the adjustment is completed, the driving member is used to drive the positioning sleeve to move upward and sleeve the first positioning plate. Under the action of the positioning sleeve, the first positioning plate presses against the outer wall of the water connection pipe, and the first positioning plate presses against the water connection pipe to fix the position of the telescopic pipe sleeve, thus completing the sliding and fixing work of the position of the telescopic pipe sleeve on the water connection pipe.

[0018] Optionally, the driving member includes:

[0019] A driving ring, the driving ring is rotatably arranged at the bottom end of the positioning sleeve. A thread is provided on the outer wall of the telescopic pipe sleeve, and a thread for threaded connection with the outer wall thread of the telescopic pipe sleeve is provided on the inner wall of the driving ring;

[0020] A rubber ring, the rubber ring is sleeved on the outer wall of the telescopic pipe sleeve below the driving ring.

[0021] By adopting the above technical solution, a thread is provided on the outer wall of the telescopic pipe sleeve. Then, by rotating the driving ring, the positioning sleeve can be driven to move up and down. The structure is simple, the operation is convenient, and the work efficiency is high. When the driving ring moves to the target position, the rubber ring is moved to sleeve on the telescopic pipe sleeve below the driving ring, thereby fixing the height of the driving ring and reducing the probability of the driving ring moving due to external vibration and other factors.

[0022] Optionally, the second positioning component includes:

[0023] A second positioning block, a horizontal sliding groove is provided on the outer wall of one end of the water connection pipe that slides in the telescopic pipe sleeve, and the second positioning block is slidably arranged on the sliding groove;

[0024] A second positioning spring, the second positioning spring is arranged on the sliding groove and connected to the second positioning block. The second positioning block partially extends out of the sliding groove under the action of the second positioning spring and presses against the inner wall of the telescopic pipe sleeve;

[0025] A moving member, the moving member is arranged on the water connection pipe and is used to drive the second positioning block to move horizontally.

[0026] By adopting the above technical solution, the moving member is used to drive the second positioning block to compress the second positioning spring and integrally move into the sliding groove, then the limit of the second positioning block on the water connection pipe can be released, and the water connection pipe can be moved to adjust the height of the water outlet tray. After the adjustment is completed, the moving member is stopped, and the second positioning block partially extends out of the sliding groove under the action of the second positioning spring and presses against the inner wall of the telescopic pipe sleeve, then the position of the water connection pipe can be fixed, thus completing the adjustment and fixing work of the height of the water connection pipe.

[0027] Optionally, the moving member includes:

[0028] A moving rod, a horizontal moving space is provided inside the side wall of the water passing pipe, the top of the moving space is communicated with the sliding groove, the moving rod is located in the moving space and the top end is connected to the second positioning block;

[0029] A moving column, a horizontal through hole is provided on the outer side wall of the water passing pipe, the through hole is communicated with the bottom of the moving space, one end of the moving column is connected to the bottom end of the moving rod, and the other end of the moving column horizontally extends out of the through hole.

[0030] By adopting the above technical solution, pressing the moving column causes the moving column to move, driving the moving rod to move, the moving rod drives the second positioning block to compress the second positioning spring and move, and when the second positioning block compresses the second positioning spring and moves, it disengages from the inner side wall of the telescopic pipe sleeve, so that the water passing pipe can be moved to adjust the height of the water passing pipe. After the adjustment is completed, releasing the moving column, while the second positioning spring rebounds, it drives the moving rod to move back to its original position, and the moving rod moving back to its original position drives the moving column to extend out of the through hole, thus completing the movement work of the second positioning block.

[0031] Optionally, an anti-slip rubber pad is provided on the side wall of the first positioning plate close to the water receiving plate.

[0032] By adopting the above technical solution, an anti-slip rubber pad is installed on the side wall of the first positioning plate close to the water receiving plate. Thus, when the first positioning plate abuts against the water receiving pipe, the anti-slip rubber pad buffers the rigid collision between the first positioning plate and the water receiving pipe, reducing the probability of wear between the first positioning plate and the water receiving pipe, and the anti-slip rubber pad increases the friction between the first positioning plate and the water receiving pipe, improving the fixing effect.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. By vertically sleeving a telescopic pipe sleeve on the water collecting pipe and then vertically sliding and installing a water passing pipe connected to the water outlet tray on the telescopic pipe sleeve. When installing the nozzle, according to the storey height of the on-site building, the position of the telescopic pipe sleeve on the water receiving pipe can be adjusted by unlocking the first positioning component first, so as to adjust the height of the water outlet tray. When the height of the adjusted water outlet tray reaches the target position, lock the first positioning component; when the adjusted height has not reached the target position, then unlock the second positioning component to adjust the position of the water passing pipe on the telescopic pipe sleeve, so as to perform a secondary adjustment on the height of the water outlet tray, so that the position of the water outlet tray can be adapted to the storey height of the building. By using the two height adjustment operations of the telescopic pipe sleeve and the water passing pipe, the adaptability of the water outlet position of the water outlet tray to buildings with different storey heights is improved;

[0035] 2. By providing threads on the outer sidewall of the telescopic pipe sleeve, the positioning sleeve can be driven to move up and down by rotating the driving ring. The structure is simple, the operation is convenient, and the working efficiency is high. After the driving ring moves to the target position, the moving rubber ring is sleeved on the telescopic pipe sleeve below the driving ring, thereby fixing the height of the driving ring and reducing the probability of the driving ring moving due to external vibrations and other factors.

[0036] 3. By installing an anti-slip rubber pad on the sidewall of the first positioning plate close to the water receiving plate, when the first positioning plate abuts against the water connection pipe, the anti-slip rubber pad buffers the rigid collision between the first positioning plate and the water connection pipe, reducing the probability of wear between the first positioning plate and the water connection pipe. Moreover, the anti-slip rubber pad increases the friction force between the first positioning plate and the water connection pipe, improving the fixing effect. Brief Description of the Drawings

Detailed Description of the Embodiments

[0042] The following Figure 1 - Figure 3 further describes the present application in detail with reference to the attached

[0043] The embodiment of the present application discloses a fire sprinkler head.

[0044] Referring to Figure 1, the fire sprinkler includes a water connection pipe 1 and a water outlet plate 11 rotatably arranged on the water connection pipe 1. The water connection pipe 1 is communicated with the water pipe on the roof. After the water connection pipe 1 is filled with water, the water is led to the water outlet plate 11. A number of nozzles 12 are evenly distributed and fixed on the circumferential side of the water outlet plate 11. A telescopic mechanism 2 is arranged on the water connection pipe 1. The water outlet plate 11 is connected to the water connection pipe 1 through the telescopic mechanism 2, and the telescopic mechanism 2 adjusts the distance between the water outlet plate 11 and the water connection pipe 1.

[0045] Refer to Figure 1 and Figure 2 , the telescopic mechanism 2 includes a telescopic pipe sleeve 21, a water connection pipe 22, a first positioning component 23 and a second positioning component 24. The telescopic pipe sleeve 21 is vertically slidably installed on the water connection pipe 1. The first positioning component 23 is arranged on the telescopic pipe sleeve 21 and is used to fix the position of the telescopic pipe sleeve 21 on the water connection pipe 1.

[0046] Refer to Figure 2 and Figure 3 , the first positioning component 23 includes a first positioning plate 31, a positioning sleeve 32 and a driving component 33. The first positioning plate 31 is rotatably installed on the upper surface of the telescopic pipe sleeve 21. There are a plurality of first positioning plates 31, and the plurality of first positioning plates 31 are evenly distributed and fixedly installed on the upper surface of the telescopic pipe sleeve 21 along the circumferential direction of the water connection pipe 1. An anti-slip rubber pad 13 is fixedly installed on the side wall of the first positioning plate 31 close to the water connection pipe 1. The positioning sleeve 32 is vertically slidably sleeved on the outer side wall of the telescopic pipe sleeve 21, and the driving component 33 is arranged on the telescopic pipe sleeve 21 and is used to drive the positioning sleeve 32 to move.

[0047] Refer to Figure 2 and Figure 3 , the driving component 33 includes a driving ring 34 and a rubber ring 35. A thread is provided on the outer side wall of the telescopic pipe sleeve 21. The driving ring 34 is fixedly installed on the lower surface of the positioning sleeve 32 and is threadedly connected to the outer side wall of the telescopic pipe sleeve 21. The rubber ring 35 is sleeved on the outer side wall of the telescopic pipe sleeve 21 and abuts against the lower surface of the driving ring 34.

[0048] Refer to Figure 2 and Figure 3, the moving rubber ring 35 disengages from the driving ring 34, and then rotating the driving ring 34 can drive the positioning sleeve 32 to move up and down. When the positioning sleeve 32 moves downward, it disengages from the first positioning plate 31. The disengagement of the positioning sleeve 32 from the first positioning plate 31 causes the first positioning plate 31 to lose the acting force of the positioning sleeve 32 and no longer press against the outer wall of the water connection pipe 1. Then, the telescopic pipe sleeve 21 can be moved to adjust the position of the telescopic pipe sleeve 21. When the positioning sleeve 32 moves upward, the positioning sleeve 32 will cover the outer walls of multiple first positioning plates 31. Under the action of the positioning sleeve 32, the first positioning plate 31 presses against the outer wall of the water connection pipe 1. The first positioning plate 31 pressing against the water connection pipe 1 fixes the position of the telescopic pipe sleeve 21, thus completing the sliding and fixing work of the position of the telescopic pipe sleeve 21 on the water connection pipe 1.

[0049] Refer to Figure 2 , the water through pipe 22 is vertically slidably installed on the telescopic pipe sleeve 21, and the water outlet pipe is fixedly installed on the lower surface of the water through pipe 22 and is internally connected to the water through pipe 22. The second positioning assembly 24 is arranged on the water through pipe 22 and is used to fix the position of the water through pipe 22 on the telescopic pipe sleeve 21.

[0050] Refer to Figure 2 and Figure 4 , the second positioning assembly 24 includes a second positioning block 41, a second positioning spring 42 and a moving member 43. A horizontal sliding groove is formed on the outer wall at the top of the water through pipe 22. The second positioning block 41 is slidably installed on the sliding groove. One end of the second positioning spring 42 is fixedly connected to the inner bottom wall of the sliding groove, and the other end of the second positioning spring 42 is fixedly connected to the second positioning block 41. The second positioning block 41 partially extends out of the sliding groove under the action of the second positioning spring 42 and presses against the inner wall of the telescopic pipe sleeve 21.

[0051] Refer to Figure 2 and Figure 4 , the moving member 43 is arranged on the water through pipe 22 and is used to drive the second positioning block 41 to move horizontally. The moving member 43 includes a moving rod 44 and a moving column 45. A horizontal moving space is formed inside the side wall of the water through pipe 22, and the top of the moving space is communicated with the sliding groove. A through hole horizontally communicated with the moving space is formed on the outer wall of the water through pipe 22. The moving rod 44 is located in the moving space, and the top end of the moving rod 44 is fixedly connected to the lower surface of the second positioning block 41. The bottom end of the moving rod 44 extends to the through hole. The moving column 45 is fixedly connected to the bottom end of the moving rod 44 and extends out of the through hole.

[0052] Refer to Figure 2 and Figure 4, press the moving column 45. The movement of the moving column 45 drives the movement of the moving rod 44. The movement of the moving rod 44 drives the second positioning block 41 to compress the second positioning spring 42 and move. When the second positioning block 41 compresses the second positioning spring 42 and moves, it disengages from the inner side wall of the telescopic pipe sleeve 21, and then the movable water pipe 22 can be moved to adjust the height of the water pipe 22. After the adjustment is completed, release the moving column 45. The second positioning spring 42 rebounds, and the second positioning block 41 partially extends out of the sliding groove under the action of the second positioning spring 42 and abuts against the inner side wall of the telescopic pipe sleeve 21. At the same time that the second positioning spring 42 rebounds, it drives the moving rod 44 to move back to its original position. The moving rod 44 moving back to its original position drives the moving column 45 to extend out of the through hole, thus completing the movement of the second positioning block 41.

[0053] The working principle of the embodiment of the present application is as follows:

[0054] The telescopic pipe sleeve 21 is vertically slidably sleeved on the water collecting pipe, and the water pipe 22 connected to the water outlet tray 11 is vertically slidably installed on the telescopic pipe sleeve 21. Then, when installing the nozzle, according to the storey height of the on-site building, the position of the telescopic pipe sleeve 21 on the water connection pipe 1 can be adjusted by rotating the driving ring 34 first, so as to adjust the height of the water outlet tray 11; when the adjusted height has not reached the target position, then hold the moving column 45 to adjust the position of the water pipe 22 on the telescopic pipe sleeve 21, so as to perform a secondary adjustment on the height of the water outlet tray 11, so that the position of the water outlet tray 11 can be adapted to the storey height of the building. By using the two height adjustment operations of the telescopic pipe sleeve 21 and the water pipe 22, the adaptability of the water outlet position of the water outlet tray 11 to buildings with different storey heights is improved.
