Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically a building fire sprinkler system. Background Technology

[0002] A fire sprinkler system is an automatic fire-fighting facility mainly used for fire extinguishing and fire control. It consists of sprinklers, pipes, water pumps, and water tanks, and is usually installed on the ceiling or walls of a building. When the system detects a fire or is manually activated, the sprinklers release water to form a mist to extinguish the fire or reduce the heat of the fire. This system can respond quickly when a fire occurs, helping to reduce the spread of the fire and protect the safety of people and property.

[0017] When the fire source in the application scenario of this intelligent fire sprinkler system increases, the smoke sensor detects an increase in smoke and transmits the signal to the microcontroller. After processing the signal, the microcontroller sends a control signal to the electric telescopic rod, which then starts to drive.

At this time, the grooves at both ends of the sprinkler pipe slide along the surface of the slider, and the sprinkler pipe rotates around the spherical shell. During this process, the sprinkler pipe continues to rotate. When the sprinkler pipe rotates to the rear and presses against the adjusting rod, the spring is compressed. When the sprinkler pipe rotates away from the adjusting rod, the spring loses pressure and pushes the guide slider forward. At this time, the guide slider moves forward along the direction of the guide groove, pushing the adjusting rod forward. The adjusting rod continues to push the sprinkler pipe forward, thereby changing the sprinkler area by adjusting the angle of the sprinkler pipe, which is convenient for adjusting the sprinkler area according to the size of the fire source.

[0026] Please see Figure 1-6 This embodiment provides a technical solution: a building fire sprinkler system, including a support plate 1, a sprinkler mechanism 2, and an adjustment mechanism 3;

[0027] Support plate 1: A water tank 9 is provided at its upper end. A water supply pipe 4 is provided at the outlet of the water tank 9. The lower end of the water supply pipe 4 is located inside the through hole opened on the upper side wall of the support plate 1.

The connecting water pipe 21 is fixedly connected to the inner wall of the inner ring of the sealed bearing 5. The lower end of the water supply pipe 4 is located inside the upper end of the connecting water pipe 21. The lower end of the connecting water pipe 21 is fixedly connected to the spherical shell 22.

The lower end of 23 is provided with a spray pipe 24, and the lower end of the spray pipe 24 is fixedly connected to a spray plate 27. Spray nozzles 28 are provided at the evenly distributed spray outlets on the lower side wall of the spray plate 27. The water pipe 21, spherical shell 22, spherical groove 23, spray pipe 24, and spray plate 27 are connected. The spray mechanism 2 also includes a sliding groove 25 and a slider 26. Slider 26 is provided at both the front and rear ends of the outer arc of the spherical shell 22. Slider grooves 25 are provided at both the front and rear ends of the inner wall of the spherical groove 23. The sliders 26 are slidably connected to the interior of the longitudinally adjacent sliding grooves 25. The staff will then install this intelligent fire protection system. After the sprinkler system is installed in the appropriate location, the staff connects the external water pipe to the inlet of water tank 9. When a fire source occurs, smoke is generated. When smoke sensor 11 detects the smoke, it transmits a signal to microcontroller 10. After processing the signal, microcontroller 10 sends a control signal to water pump 8. Under the control of microcontroller 10, water pump 8 starts to drive, drawing water from inside water tank 9 and transporting it along water pipe 4 to the inside of connecting water pipe 21. At the same time, microcontroller 10 sends a control signal to motor 7, which starts to drive, and then the motor... The output shaft of 7 drives pulley 13 to rotate, which in turn drives belt 15 to rotate. Under the transmission action of belt 15, pulley 14 rotates synchronously, which in turn drives water pipe 21 to rotate, which in turn drives the ball shell 22 at the lower end of water pipe 21 to rotate. At this time, under the mutual restriction of slider 26 and slide groove 25, the ball groove 23 rotates synchronously, which in turn drives spray water pipe 24 to rotate, which in turn drives spray plate 27. At this time, the water inside the water pipe 21 flows downward continuously and is then sprayed out through the nozzle 28 at the lower end of spray plate 27, which facilitates timely spraying when a fire source is discovered.

[0029] Adjustment mechanism 3: It is located at the rear end of the lower side of the support plate 1. The front end of the adjustment mechanism 3 is installed in conjunction with the middle of the sprinkler mechanism 2. The adjustment mechanism 3 includes a mounting plate 31, a sliding barrel 32, an adjusting rod 33, a guide slider 34, a guide groove 35, and a spring 36. The mounting plate 31 is located at the rear end of the lower side of the support plate 1.

A spring 36 is fixedly connected between the guide slider 34 and the rear inner wall of the sliding barrel 32. The front end of the guide slider 34 is fixedly connected to the adjusting rod 33. The front end of the adjusting rod 33 is in contact with the sprinkler water pipe 24. When the fire source in the application scenario of this intelligent fire sprinkler system increases, the smoke sensor 11 senses the increase in smoke. The smoke sensor 11 transmits the signal to the microcontroller 10. After processing the signal, the microcontroller 10 sends a control signal to the electric telescopic rod 12. The electric telescopic rod 12 is driven, and the telescopic end of the electric telescopic rod 12 pulls the slide barrel 32 forward, which in turn drives the guide slider 34 to move forward, which in turn drives the adjusting rod 33 to move forward, which in turn pushes the spray pipe 24 to move. At this time, the sliding grooves 25 at both ends of the spray pipe 24 slide along the surface of the slider 26, and the spray pipe 24 rotates around the spherical shell 22. During this process, the spray pipe 24 continues to rotate. When the spray pipe 24 rotates to the rear and squeezes the adjusting rod 33, the spring 36 is under pressure. When the spray pipe 24 rotates away from the adjusting rod 33, the spring 36 loses pressure and pushes the guide slider 34 forward. At this time, the guide slider 34 moves forward along the direction of the guide groove 35, which in turn pushes the adjusting rod 33 forward. At this time, the adjusting rod 33 continues to push the spray pipe 24 forward, thereby changing the spray area by the angle of the spray pipe 24. When the fire source in the usage scenario increases, the spray area is adaptively increased.

[0030] The system also includes: a microcontroller 10, which is mounted on the upper side of the support plate 1. The input terminals of the microcontroller 10 are electrically connected to an external power supply and the output terminal of the smoke sensor 11. It also includes a water pump 8, which is connected in series in the middle of the water supply pipe 4. The input terminal of the water pump 8 is electrically connected to the output terminal of the microcontroller 10. Finally, it includes an electric telescopic rod 12, which is bolted to the front side of the mounting plate 31. The telescopic end of the electric telescopic rod 12 passes through the front sidewall of the mounting plate 31 and is fixedly connected to the upper rear end of the sliding drum 32. The input end of the electric telescopic rod 12 is electrically connected to the output end of the microcontroller 10. It also includes a motor 7, which is bolted to the front side of the upper side of the support plate 1. The input end of the motor 7 is electrically connected to the output end of the microcontroller 10. The output shaft of the motor 7 passes through the upper side wall of the support plate 1. A pulley 13 is provided at the end of the output shaft of the motor 7. The pulley 13 coincides with the central axis of the output shaft of the motor 7. A pulley 24 is provided in the middle of the outer arc surface of the water pipe 21. The pulley 13 and the pulley 24 are connected by a belt 15.

[0031] The working principle of the building fire sprinkler system provided by this utility model is as follows: First, after the staff installs the intelligent fire sprinkler system in a suitable location, they connect the external water pipe to the inlet of the water tank 9. When a fire occurs, smoke is generated. When the smoke sensor 11 detects the smoke, it transmits a signal to the microcontroller 10. After processing the signal, the microcontroller 10 sends a control signal to the water pump 8. Under the control of the microcontroller 10, the water pump 8 starts to drive. At this time, the water pump 8 draws water from the water tank 9 and transports it along the water supply pipe 4 to the inside of the connecting water pipe 21. At the same time, the microcontroller 1... The controller sends a control signal to motor 7. After being controlled by microcontroller 10, motor 7 starts driving. The output shaft of motor 7 drives pulley 13 to rotate, which in turn drives belt 15. Under the transmission of belt 15, pulley 14 rotates synchronously, driving the connecting water pipe 21 to rotate. This, in turn, drives the ball shell 22 at the lower end of the connecting water pipe 21 to rotate. At this time, under the mutual restraint of slider 26 and slide 25, the ball groove 23 rotates synchronously, driving the spray pipe 24 to rotate, which in turn drives the spray plate 27. Water inside the connecting water pipe 21 continuously flows downwards and then through the spray plate 27. The nozzle 28 at the lower end of the system sprays water. When the fire source in the application scenario of this intelligent fire sprinkler system increases, the smoke sensor 11 detects an increase in smoke and transmits the signal to the microcontroller 10. After processing the signal, the microcontroller 10 sends a control signal to the electric telescopic rod 12, which then starts to drive. The telescopic end of the electric telescopic rod 12 pulls the slide barrel 32 forward, which in turn moves the guide slider 34 forward, which in turn moves the adjusting rod 33 forward, thus pushing the sprinkler pipe 24 to move. At this time, the sliding grooves 25 at both ends of the sprinkler pipe 24 slide along the surface of the slider 26. Then the spray pipe 24 rotates around the spherical shell 22. During this process, the spray pipe 24 continues to rotate. When the spray pipe 24 rotates to the rear and presses the adjusting rod 33, the spring 36 is under pressure. When the spray pipe 24 rotates away from the adjusting rod 33, the spring 36 loses pressure and pushes the guide slider 34 forward. At this time, the guide slider 34 moves forward along the direction of the guide groove 35, which in turn pushes the adjusting rod 33 forward. At this time, the adjusting rod 33 continues to push the spray pipe 24 forward, thereby changing the spray area by the angle of the spray pipe 24.

[0032] It is worth noting that the motor 7 disclosed in the above embodiments can be model YE2-80M-4, the smoke sensor 11 can be model GQQ0.1012, the microcontroller 10 can be model C200H-MR832PLC, and the electric telescopic rod 12 can be model FY0141. The microcontroller 10 controls the operation of the electric telescopic rod 12 and the motor 7 using methods commonly used in the prior art.
