[0015] Preferably, the bottom of the pushing ring is fixedly provided with a plurality of T-shaped rods I in the circumferential direction.

[0016] A sliding strip is fixedly arranged on the adjusting plate, a T-shaped groove is formed in the sliding strip, and the T-shaped rod I is slidably arranged along the T-shaped groove.

DETAILED DESCRIPTION

[0035] Please refer to Figures 1-7 In the embodiment of the application, a high-rise building fire-fighting modular intelligent spraying system comprises:

[0036] The nozzle body 1 comprises a body pipeline 11 arranged vertically and two bypass pipelines 12 symmetrically connected to the two sides of the body pipeline 11.

[0037] The adjusting mechanism 2 is fixedly installed at the lower end of the body pipeline 11.

[0038] The drive mechanism 3 is used for driving the adjusting mechanism 2 and is fixedly installed on the body pipeline 11.

[0039] The adjusting mechanism 2 comprises an adjusting seat 21, an adjusting plate 22, a connecting rod one 23, a connecting rod two 24 and an elastic water curtain 25. The adjusting seat 21 is fixedly installed at the lower end of the body pipeline 11. The outer side of the adjusting seat 21 is uniformly rotationally provided with a plurality of adjusting plates 22 in the circumferential direction. The two sides of each adjusting plate 22 are symmetrically and slidingly provided with a connecting rod one 23 and a connecting rod two 24. The connecting rod one 23 and the connecting rod two 24 are slidingly sleeved. The end of the connecting rod one 23 is fixedly provided with a ball head 231. The end of the connecting rod two 24 is fixedly provided with a ball socket 241 matched with the ball head 231. Adjacent two adjusting plates 22 are interconnected through the rotational connection of the ball head 231 and the ball socket 241. The elastic water curtain 25 is fixedly covered below the plurality of adjusting plates 22 and the plurality of connecting rod ones 23 and connecting rod twos 24.

[0040] It is important to note that all the adjusting plates 22 are hinged together by a ball joint formed by connecting rod 1 23, connecting rod 24, and the ball joint 231 and ball socket 241 between them. This means that multiple adjusting plates 22, connecting rod 1 23, and connecting rod 24 form a closed-loop linkage. When one adjusting plate 22 deflects, it pushes connecting rod 1 23 and connecting rod 24 to slide. Connecting rod 1 23 and connecting rod 24 then transmit this force to the adjacent adjusting plate 22, causing the other adjusting plate 22 to move in the same direction. Furthermore, due to the ball joint, connecting rod 1 23 and connecting rod 24 self-adaptively rotate during sliding, thus compensating for the movement. The relative positional change of two adjacent adjusting plates 22 during deflection ensures smooth and unobstructed linkage. Since the distance between the ends of the two adjacent adjusting plates 22 furthest from the adjusting seat 21 is larger, while the distance between the ends closer to the adjusting seat 21 is smaller, connecting rod 1 23 and connecting rod 24 are designed to be sleeved. This allows for a longer sliding distance between connecting rod 1 23 and connecting rod 24, fully meeting the hinge requirements between the two adjacent adjusting plates 22. Furthermore, multiple connecting rods 1 23 and connecting rod 24 can fill the gaps between the two adjacent adjusting plates 22, thus providing support for the elastic water curtain 25. This ensures that the linked annular plate structure can effectively block and guide the 360° water flow.

[0041] In this embodiment, an annular plate 13 is fixedly installed at the bottom of the main pipe 11. Multiple nozzles 14 are circumferentially opened on the pipe wall of the main pipe 11 above the annular plate 13. The adjustment mechanism 2 is located above the nozzles 14. An mounting base is installed on the annular plate 13. Two support rods are fixedly installed at the bottom of the annular plate 13. A splash plate is fixedly installed at the end of the two support rods. A temperature-sensing glass ball is installed between the splash plate and the mounting base.

[0042] In other words, the main pipe 11 is still a traditional temperature-sensitive sprinkler head structure. When the temperature reaches a certain level, the temperature-sensitive glass ball will break, causing the mounting base to detach from the annular plate 13, thereby opening the main pipe 11 and allowing fire water to spray onto the splash plate from this opening, thus performing the initial fire-fighting function. That is, when the adjustment mechanism 2 or the drive mechanism 3 becomes stuck, the sprinkler head body 1 will not lose its most basic fire-fighting function.

[0043] In this embodiment, the driving mechanism 3 includes a rotating seat 31, a rotating shaft 32, an impeller mechanism 33, and a turntable 34. The rotating seat 31 is fixedly installed on the main pipeline 11, and a cylindrical cavity communicating with the main pipeline 11 is formed inside it. The rotating shaft 32 is rotatably installed on the rotating seat 31, and its two ends pass through the rotating seat 31. The impeller mechanism 33 is fixedly installed on the rotating shaft 32 and located in the cylindrical cavity. Two turntables 34 are configured and fixedly installed at the two ends of the rotating shaft 32 that extend out of the rotating seat 31.

[0044] In this embodiment, extension seats 35 are fixedly installed on both sides of the rotating seat 31. The extension seat 35 has a rotating groove for the turntable 34 to rotate. The extension seat 35 has a sliding groove 351 in the vertical direction. The sliding groove 351 and the rotating groove are connected by a vertical groove. A support rod 352 is slidably arranged in the sliding groove 351. A guide rod 353 is fixedly arranged on the support rod 352. The bottom of the guide rods 353 on the two extension seats 35 are fixedly connected to a push ring 354.

[0045] An annular groove 341 is formed on the turntable 34, and the guide rod 353 passes through the vertical groove and slides along the annular groove 341.

[0046] In this embodiment, a plurality of T-shaped rods 355 are fixedly provided circumferentially at the bottom of the push ring 354;

[0047] A slide bar 221 is fixedly installed on the adjusting plate 22. A T-slot 222 is provided in the slide bar 221. The T-shaped rod 355 is slidably installed along the T-slot 222.

[0048] This embodiment also includes:

[0049] The sensing unit includes multiple distributed temperature, smoke, flame, and carbon monoxide sensors.

[0050] The central control unit is communicatively connected to the sensing unit;

[0051] The solenoid valve assembly is installed on the main water supply pipeline and is electrically connected to the central control unit.

[0052] In practice, the sensing unit can be used to warn of fires and identify fire conditions. When a fire occurs, the sensing unit can quickly detect the fire and transmit data to the central control unit. The central control unit controls the solenoid valve group to open based on the transmitted data, allowing the main fire water supply pipeline to supply water into the sprinkler body 1. Subsequently, the fire water will flow along the main pipeline 11 to the nozzle 14 and spray out from the nozzle 14. At the same time, the impeller mechanism 33 in the drive mechanism 3 will rotate under the force of the water flow, thereby driving the turntable 34 to rotate through the rotating shaft 32. The rotation of the turntable 34 further drives the guide rod 353 to slide along the annular groove 341, thereby causing the support rod 352 to slide up and down along the sliding groove 351. The sliding of the support rod 352 further drives the push ring 354 to slide up and down. At this time, the T-shaped rod 355 will slide along the T-shaped groove 222, and at the same time drive the multiple adjusting plates 22 to deflect up and down along the adjusting seat 21, thereby changing the angle of the water jet sprayed from the nozzle 14, thereby changing the spray range of a single nozzle, eliminating its spray blind zone, and improving the fire extinguishing effect.

[0053] In this embodiment, the bypass pipe 12 has a horizontal inlet and a horizontal outlet, with the inlet located above the drive mechanism 3 and the outlet located below the drive mechanism 3. A piston 121 is slidably and sealed in the bypass pipe 12, with the piston 121 located above the outlet and blocking it. A shear pin is provided between the piston 121 and the inner wall of the bypass pipe 12.

[0054] In this embodiment, a drive ring 111 and a sealing ring 112 are slidably disposed in the main pipeline 11. A plurality of T-shaped rods 113 are fixedly disposed on the sealing ring 112. A plurality of through holes are provided on the drive ring 111 for the T-shaped rods 113 to pass through, and a spring 114 located between the drive ring 111 and the sealing ring 112 is sleeved on the T-shaped rods 113.

[0055] In this embodiment, a plurality of arc-shaped sealing blocks 115 are fixedly provided on the sealing ring 112, and the arc-shaped sealing blocks 115 can block the nozzle 14;

[0056] The drive ring 111 is fixedly connected to the two pistons 121 by two L-shaped rods 116.

[0057] Specifically, when the regulating mechanism 2 or the drive mechanism 3 becomes blocked, the impeller mechanism 33 will not rotate when water flows through the main pipe 11. The impeller mechanism 33 will then block the main pipe 11, reducing or completely blocking the water flow channel. This increases the pressure in the main pipe 11 above the drive mechanism 3, meaning the pressure in the bypass pipe 12 will also increase. When the pressure exceeds the threshold of the shear pin, the shear pin will break. At this point, the piston 121 will slide down the bypass pipe 12 and open its outlet, allowing fire water to flow smoothly to the bottom of the main pipe 11. During the sliding process of the piston 121… It can push the drive ring 111 downward through the L-shaped rod. The downward sliding of the drive ring 111 can further push the sealing ring 112 downward, thereby causing the arc-shaped sealing block 115 to block the nozzle 14. At the same time, due to the jamming of the adjustment mechanism 2 or the drive mechanism 3, the nozzle body 1 does not produce a fire-fighting effect. As the temperature rises, the temperature-sensing liquid inside the temperature-sensing glass ball will expand due to the high temperature and burst the temperature-sensing glass ball, thereby causing the mounting base to detach from the annular plate 13, allowing the fire-fighting water to flow out of the main pipe 11 and spray around through the splash plate, that is, to carry out the most basic spraying work, thereby ensuring that the nozzle body 1 can effectively spray fire-fighting water after a fire occurs.

[0058] In other words, the sprinkler head body 1 has two spraying modes: the first is an oscillating spraying mode formed by the adjustment mechanism 2 and the drive mechanism 3. In this mode, the range of the sprinkler head can change as the spraying occurs, thereby eliminating the blind spots of a single sprinkler head and improving the fire-fighting effect. Then, when the adjustment mechanism 2 or the drive mechanism 3 becomes blocked, making the first mode impossible, the sprinkler head body 1 will switch to the most basic spraying mode, which is to sense the temperature through the temperature sensing element. Then, the temperature sensing element, i.e., the temperature sensing glass ball, breaks, allowing fire water to spray in all directions through the action of the splash plate. By combining the two modes, the sprinkler head body 1 can not only ensure the most basic spraying effect but also have an additional oscillating spraying effect, thereby effectively improving the fire extinguishing effect of the sprinkler head.

[0059] Specifically, this invention enables dynamic adjustment of the spray range of the nozzle body 1 through the action of the drive mechanism 3 and the adjustment mechanism 2, thereby effectively eliminating the spray blind zone of a single nozzle, expanding the coverage area, and improving fire extinguishing efficiency. The impeller mechanism 33 in the drive mechanism 3 is mainly driven by water flow power, while the adjustment plate 22 is linked with the rotary wheel mechanism 33 through the turntable 34, guide rod 353, and push ring 354. Therefore, no additional power is needed to drive the drive mechanism 3. Dynamic adjustment of the nozzle spray range can be achieved simply by the normal operation of the spraying. In addition, when the adjustment mechanism 2 and the drive mechanism 3 become blocked, the nozzle can automatically switch to the basic spraying mode. That is, the piston 121 in the bypass pipe 12 slides under pressure and opens its outlet, while blocking the nozzle 14, forcing the water flow through the temperature-sensing glass ball to spray the water from the splash plate. This ensures that even if the drive mechanism 3 and the adjustment mechanism 2 fail, the nozzle body 1 still has basic fire-fighting functions, thereby improving the reliability of the system.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
