Description

Technical Field

[0001] This application relates to the technical field of fire sprinkler heads, and in particular to an adjustable-angle automatic rotating fire sprinkler head. Background Technology

[0002] Fire sprinkler heads are a key component widely used in automatic fire sprinkler systems. They are typically installed on the ceiling or walls of buildings. When a fire occurs, the sprinkler heads automatically respond to temperature changes or other fire signals at the fire scene, spraying water in a specific manner to extinguish the fire or control its spread.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the prior art, sprinkler heads cannot adjust the spray angle, which may lead to blind spots in the spray range, preventing some areas from being covered by water, thus affecting the fire extinguishing effect and causing greater impact. Utility Model Content

[0004] In order to allow for adjustment of the sprinkler head angle, this application provides an adjustable-angle automatic rotating fire sprinkler head.

[0005] This application provides an adjustable-angle automatic rotating fire sprinkler head, which adopts the following technical solution: it includes an assembly plate, a water supply pipe is fixedly connected to the top of the assembly plate, and a connecting pipe is provided below the assembly plate;

[0006] An electric push rod is provided below the assembly plate. A push rod is fixedly connected to the bottom output end of the electric push rod. A moving block is fixedly connected to the bottom of the push rod. A rotating column is rotatably connected to the right side of the moving block. A rotating plate is fixedly connected to the right side of the rotating column. A nozzle is provided to the left side of the rotating column.

[0007] Optionally, a rotating ring is fixedly connected to the bottom of the assembly plate, the bottom of the rotating ring is fixedly connected to the top of the connecting pipe, and a fixing ring is fixedly connected to the outer wall of the connecting pipe.

[0008] Optionally, a telescopic barrel is fixedly connected to the bottom of the fixing ring, and a telescopic column is slidably connected to the inner wall of the telescopic barrel.

[0009] Optionally, the bottom of the telescopic column is fixedly connected to the top of the movable block, and the inner wall of the movable block is in contact with the outer wall of the connecting pipe.

[0010] Optionally, the top of the electric push rod is fixedly connected to the bottom of the fixing ring, and a water outlet pipe is fixedly connected to the outer wall of the connecting pipe.

[0011] Optionally, a nozzle is rotatably connected to the right side of the water outlet pipe, and a fixing hole is present on the right side of the rotating plate.

[0012] Optionally, the inner wall of the fixing hole is fixedly connected to the outer wall of the nozzle, the number of nozzles is several, and the several nozzles are arranged in a ring array, the number of rotating plates is several, and the several rotating plates are arranged in a ring array.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model is equipped with components such as an electric push rod, a push rod, and a nozzle. The electric push rod is activated, causing the push rod to drive the rotating plate to rotate upward. Since the rotating plate and the rotating column are rotatably connected, the rotating plate will simultaneously drive the nozzle to rotate after rotating upward. This allows the device to adjust the spray angle of the nozzle, avoiding blind spots in the spray range and preventing some areas from being covered by water, thus affecting the fire extinguishing effect.

[0015] 2. This utility model incorporates components such as a connecting pipe and a rotating ring. Water is supplied through a water pipe into the connecting pipe, and then the water is sprayed out from the nozzles through the outlet pipe. Since there are several nozzles arranged in a ring, when several nozzles spray water simultaneously, they will cause the connecting pipe to rotate under the constraint of the rotating ring. This allows the device to rotate using the force of the water spraying out, enabling it to rotate without a power source. At the same time, the centrifugal force of the rotation can be used to increase the coverage area of ​​the spray and improve the fire extinguishing effect. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-4This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] This application discloses an adjustable-angle automatic rotating fire sprinkler head. For example... Figure 1 , Figure 3 As shown, it includes an assembly plate 1, a water supply pipe 11 is fixedly connected to the top of the assembly plate 1, and a connecting pipe 12 is provided below the assembly plate 1.

[0023] In this embodiment, an electric push rod 3 is provided below the assembly plate 1. A push rod 31 is fixedly connected to the bottom output end of the electric push rod 3. A moving block 32 is fixedly connected to the bottom of the push rod 31. The outer walls of the electric push rod 3 and the push rod 31 are coated with a waterproof coating to prevent them from being corroded and to extend the service life of the equipment. A rotating column 34 is rotatably connected to the right side of the moving block 32. A rotating plate 341 is fixedly connected to the right side of the rotating column 34. A nozzle 331 is provided on the left side of the rotating column 34. The inner wall of the fixing hole is fixedly connected to the outer wall of the nozzle 331. There are several nozzles 331, and the several nozzles 331 are arranged in a ring array.

[0024] Please see Figure 2 As shown, a rotating ring 21 is fixedly connected to the bottom of the assembly plate 1. A water-proof plate is provided on the inner wall of the rotating ring 21 to prevent water erosion and seepage at this location. The bottom of the rotating ring 21 is fixedly connected to the top of the connecting pipe 12. A fixing ring 2 is fixedly connected to the outer wall of the connecting pipe 12. A telescopic bucket 22 is fixedly connected to the bottom of the fixing ring 2.

[0025] Please see Figure 2 As shown, a telescopic column 221 is slidably connected to the inner wall of the telescopic barrel 22. Both the telescopic column 221 and the telescopic barrel 22 are coated with a waterproof coating. At the same time, this part can also restrict the movement of the device. The bottom of the telescopic column 221 is fixedly connected to the top of the moving block 32, and the inner wall of the moving block 32 is in contact with the outer wall of the connecting pipe 12.

[0026] Please see Figure 3 As shown, the top of the electric push rod 3 is fixedly connected to the bottom of the fixed ring 2, and the water outlet pipe 33 is fixedly connected to the outer wall of the connecting pipe 12. The nozzle 331 is rotatably connected to the right side of the water outlet pipe 33.

[0027] Please see Figure 4 As shown, there are several rotating plates 341 arranged in a circular array, and there are fixing holes starting from the right side of the rotating plates 341.

[0028] The implementation principle of an adjustable-angle automatic rotating fire sprinkler head in this application embodiment is as follows: The electric push rod 31 drives the rotating plate 341 to rotate upwards. Since the rotating plate 341 and the rotating column 34 are rotatably connected, the upward rotation of the rotating plate 341 simultaneously drives the sprinkler head 331 to rotate counterclockwise. When the moving block 32 moves downwards, it drives the sprinkler head 331 to rotate clockwise via the rotating plate 341. This allows the device to adjust the spray angle of the sprinkler head 331, preventing blind spots in the spray range. To address the issue of some areas not being covered by water, thus affecting the fire extinguishing effect, water is supplied through the water pipe 11 into the connecting pipe 12. Subsequently, the water is sprayed out from the nozzles 331 through the outlet pipe 33. Since there are several nozzles 331 arranged in a ring, when several nozzles 331 spray water simultaneously, they will drive the connecting pipe 12 to rotate under the restriction of the rotating ring 21. This allows the device to rotate using the force of the water spraying, enabling the device to rotate without a power source. At the same time, the centrifugal force of the rotation can be used to increase the coverage area of ​​the spray and improve the fire extinguishing effect.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
