Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a fire-fighting autonomous sprinkler system. Background Technology

[0002] As one of the core devices for fire prevention and fighting, the autonomous fire sprinkler system plays a role in "early detection, early intervention, fire control, and loss reduction," covering the entire process from early fire warning to mid-stage fire suppression and late-stage auxiliary protection.

[0003] The existing utility model patent with publication number CN208990120U discloses an automatic fire sprinkler device, including a motor frame. A rubber pad is fixedly connected to the top of the motor frame, and a motor is fixedly connected inside the motor frame. A first rotating wheel is fixedly connected to the output shaft of the motor, and a second rotating wheel is connected to the first rotating wheel via a belt drive. A rotating shaft is fixedly connected to the axis of the second rotating wheel, and the rotating shaft is rotatably connected to the inner wall of the motor frame. This utility model relates to the field of fire protection equipment technology. This automatic fire sprinkler device, when installed in a designated location, achieves the goal of improving fire safety and timely fire suppression when a fire occurs indoors. It also achieves the goal of further fire suppression by having the motor rotate after the bottom circuit is connected, causing the rotating frame to extend and expand the detection range, thereby effectively controlling a larger area of ​​fire and increasing the fire suppression range.

[0004] The aforementioned sprinkler system is installed directly in series with the fire hydrant. When a fire occurs, all the sprinkler systems in the area will turn on at the same time, causing a drop in water pressure inside the pipe and thus affecting the sprinkler range. In addition, the sprinkler system uses polyethylene wax as a trigger, which triggers the sprinkler when it melts. This method cannot quickly shut down the sprinkler system if the polyethylene wax is accidentally damaged. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an autonomous fire sprinkler system, which solves the problems of the inability to quickly shut down the sprinkler system when the trigger element is accidentally damaged and the impact of pipeline water pressure on the sprinkler range.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fire-fighting autonomous sprinkler system includes a connecting pipe, and a sprinkler mechanism is installed inside the connecting pipe for fire sprinkler operation. The sprinkler mechanism includes:

[0007] The booster assembly includes an oil seal fixedly installed on the top of a connecting pipe, a motor fixedly installed above the connecting pipe, a drive shaft inserted through the center of the oil seal, a guide plate fixedly installed below the drive shaft, an arc plate fixedly installed above the guide plate, a limit plate fixedly installed inside the connecting pipe, and a diaphragm fixedly installed at the bottom end of the connecting pipe.

[0008] The triggering component, located at the bottom of the connecting pipe, is used to trigger the spray at high temperatures.

[0009] Preferably, the triggering component includes a connecting ring fixedly installed on the outer side of the bottom of the connecting pipe, a limiting frame fixedly installed below the connecting ring, a splash plate fixedly installed at the bottom end of the limiting frame, a limiting tube inserted through the center of the limiting frame, a rubber ring fixedly installed at the top end of the limiting tube, a thermistor glass ball fitted into the top of the limiting tube, a spring sleeved on the outer side of the limiting tube, and a silicone tube fixedly installed on the outer side of the limiting tube.

[0010] Preferably, the drive shaft is rotatably connected to the connecting pipe via an oil seal, and the outer edge of the guide plate is provided with fan-shaped notches distributed in a ring around the center of the guide plate.

[0011] Preferably, the arc plate is installed in a ring above the guide plate, the drive shaft and the limiting plate are rotatably connected, and the center of the limiting plate is provided with an opening structure distributed in a ring with the center of the limiting plate as the reference.

[0012] Preferably, the inner wall of the central opening of the disc-shaped structure of the limiting frame is provided with a threaded structure, and the upper half of the outer side of the limiting tube is provided with a threaded structure.

[0013] Preferably, the lower half of the limiting tube is slidably connected to the limiting frame, the top of the limiting tube is provided with an arc-shaped structure that fits into the thermosensitive glass ball, and the bottom end of the silicone tube is fixedly connected to the disc structure at the center of the limiting frame.

[0014] Beneficial effects

[0015] This utility model provides a self-regulating fire sprinkler system. Compared with the prior art, it has the following advantages:

[0016] (1) The fire-fighting autonomous sprinkler system has a threaded inner wall on the central opening of the disc-shaped structure of the limiting frame, and the upper half of the outer side of the limiting tube is also threaded. The lower half of the limiting tube is slidably connected to the limiting frame. The operator can pull the limiting tube down with the spline structure at the bottom of the limiting tube and rotate the limiting tube at the same time so that the thread of the upper half of the limiting tube engages with the thread of the central opening of the limiting frame, fixing the limiting tube in a lower position. At this time, a reserved space is formed between the top of the limiting tube and the connecting tube, which facilitates the quick removal of the damaged thermal glass ball and replacement with a new thermal glass ball. After the replacement is completed, the limiting tube is rotated in the opposite direction to separate the threaded connection between the limiting tube and the limiting frame. The limiting tube moves upward under the action of the spring force, lifting the new thermal glass ball again and fitting it with the diaphragm, sealing the bottom opening of the connecting tube, realizing the rapid shutdown and reset of the sprinkler system, and avoiding continuous water leakage due to damage to the trigger element.

[0017] (2) After the motor starts, the transmission shaft rotates, and the transmission shaft drives the guide plate and the arc plate to rotate synchronously. The arc plate is distributed in a ring above the guide plate. When it rotates, it can guide and squeeze the water flow in the connecting pipe, causing the water flow to concentrate and move to the fan-shaped notch on the outer edge of the guide plate. This process will create a low-pressure area between the guide plate and the limiting plate. Since the limiting plate has a ring-shaped opening structure in the center, the water flow in the horizontal pipe cavity above the connecting pipe will be continuously replenished to the low-pressure area between the guide plate and the limiting plate under the action of pressure difference. The water flow is compressed and pressurized under the continuous action of the guide plate and the arc plate. When the pressurized water flow is sprayed out through the subsequent structure, the kinetic energy is significantly increased. After hitting the splash plate, it can form a larger spray coverage, which effectively solves the problem of reduced pipeline water pressure and reduced spray range caused by multiple units being turned on at the same time in traditional devices.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a fire-fighting autonomous sprinkler device includes a connecting pipe 1, and a sprinkler mechanism 2 is installed inside the connecting pipe 1 for fire sprinkler operation. The sprinkler mechanism 2 includes: a pressurizing component 21, including an oil seal 211 fixedly installed on the top of the connecting pipe 1, a motor 212 fixedly installed above the connecting pipe 1, a drive shaft 213 inserted through the center of the oil seal 211, a guide plate 214 fixedly installed below the drive shaft 213, and an arc plate 215 fixedly installed above the guide plate 214. The internal fixed installation of the limiting plate 216, the bottom end of the connecting pipe 1 is fixedly installed with a diaphragm 217; the drive shaft 213 is rotatably connected to the connecting pipe 1 through the oil seal 211, the outer edge of the guide plate 214 is provided with a fan-shaped notch distributed in a ring with the center of the guide plate 214 as the reference, the arc plate 215 is installed in a ring above the guide plate 214, the drive shaft 213 is rotatably connected to the limiting plate 216, the center of the limiting plate 216 is provided with an opening structure distributed in a ring with the center of the limiting plate 216 as the reference.

[0025] Specifically, the motor 212 has a gearbox, which changes the orientation of the output shaft. The top of the transmission shaft 213 is fixedly connected to the output shaft of the gearbox of the motor 212. The motor 212 drives the transmission shaft 213 to rotate, which causes the guide plate 214 and the arc plate 215 fixed on the outside of the transmission shaft 213 to rotate. The water inside the pipe cavity will be compressed at the notch on the outer edge of the guide plate 214 under the action of the arc plate 215 and move downward, thereby reducing the water pressure between the guide plate 214 and the limiting plate 216. This allows the water in the horizontal pipe cavity above the connecting pipe 1 to enter between the limiting plate 216 and the guide plate 214 through the opening in the center of the limiting plate 216, thereby pressurizing the water flow before it is sprayed out, increasing the kinetic energy of the water flow when it hits the splash plate 223, and thus expanding the spray range.

[0026] Trigger assembly 22, located at the bottom end of connecting pipe 1, is used to trigger the spray at high temperatures. Trigger assembly 22 includes a connecting ring 221 fixedly installed on the outer side of the bottom of connecting pipe 1. A limit frame 222 is fixedly installed below the connecting ring 221. A splash plate 223 is fixedly installed at the bottom end of the limit frame 222. A limit tube 224 is inserted through the center of the limit frame 222. A rubber ring 225 is fixedly installed at the top end of the limit tube 224. A thermal glass ball 226 is fitted into the top of the limit tube 224. A spring 227 is sleeved on the outside of the limiting tube 224, and a silicone tube 228 is fixedly installed on the outside of the limiting tube 224. The inner wall of the central opening of the disc-shaped structure of the limiting frame 222 is provided with a threaded structure. The upper half of the outer side of the limiting tube 224 is provided with a threaded structure. The lower half of the limiting tube 224 is slidably connected to the limiting frame 222. The top of the limiting tube 224 is provided with an arc-shaped structure that fits into the thermosensitive glass ball 226. The bottom end of the silicone tube 228 is fixedly connected to the disc structure at the center of the limiting frame 222.

[0027] Specifically, the limiting bracket 222 restricts the limiting tube 224 to be located directly below the diaphragm 217. A spring 227 between the outer side of the limiting tube 224 and the limiting bracket 222 keeps the limiting tube 224 confining the thermistor glass ball 226 below the diaphragm 217, and maintains the diaphragm 217 in contact with the thermistor glass ball 226 to seal the opening at the bottom of the connecting tube 1. The thermistor glass ball 226 is filled with a thermosensitive liquid. At high temperatures, the thermosensitive liquid vaporizes and expands, causing the thermistor glass ball 226 to shatter. The limiting tube 224 will then move upwards under the influence of the spring 227, clamping the top rubber ring 225 of the connecting tube 1. Water inside the connecting tube 1 will then be sprayed through the limiting tube 224 towards the splash. When replacing the thermal glass ball 226, the position of the limiting tube 224 is adjusted downward through the spline structure at the bottom of the limiting tube 224, and the limiting tube 224 is rotated so that the threaded structure of the upper half of the outer wall of the limiting tube 224 connects the limiting tube 224 to the limiting frame 222. Space is reserved between the top of the limiting tube 224 and the connecting tube 1 for installing the thermal glass ball 226. After the thermal glass ball 226 is installed, the limiting tube 224 is rotated in the opposite direction so that the threaded structure of the limiting tube 224 separates from the limiting frame 222. Under the influence of the elastic force of the spring 227, the limiting tube 224 will push the thermal glass ball 226 upward, which cooperates with the diaphragm 217 to seal the bottom end of the connecting tube 1.

[0028] Specifically, the motor 212 is model Y2-80M1-4 with an integrated LoRa module, which can receive monitoring data from the pipeline water pressure sensor and start when the water pressure fluctuates. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] During operation, the device connects to the fire hydrant via connecting pipe 1. In the trigger assembly 22, the limiting pipe 224, under the elastic force of spring 227, lifts the thermosensitive glass bulb 226, causing it to fit tightly against the diaphragm 217 at the bottom of connecting pipe 1, thus sealing the opening at the bottom of connecting pipe 1 and preventing water from flowing out. When a fire occurs and the ambient temperature rises, the thermosensitive liquid filling the thermosensitive glass bulb 226 vaporizes and expands, eventually causing the thermosensitive glass bulb 226 to shatter. At this time, the elastic force of spring 227 pushes the limiting pipe 224 upward, and the rubber ring 225 at the top of the limiting pipe 224 clamps with the connecting pipe 1. The water flow inside the connecting pipe 1 breaks through the restriction of the diaphragm 217 and flows through the limiting pipe 224 to the splash plate 223. Simultaneously, the pressurization unit... When component 21 is started, motor 212 drives transmission shaft 213 to rotate. The guide plate 214 below transmission shaft 213 and the arc plate 215 installed in a ring above guide plate 214 rotate synchronously with transmission shaft 213. The arc plate 215 drives the water flow in connecting pipe 1 to be compressed and moved downward at the annular fan-shaped notch on the outer edge of guide plate 214, so that the water pressure between guide plate 214 and limiting plate 216 is reduced. The water flow in the horizontal pipe cavity above connecting pipe 1 enters between guide plate 214 and limiting plate 216 through the annular opening structure in the center of limiting plate 216. Before the water flow is sprayed out, it is pressurized to increase the kinetic energy of the water flow when it hits the splash plate 223. Finally, the pressurized water flow is diffused through splash plate 223 to form a large-area spray, realizing fire extinguishing operation.
