Description

Technical Field

[0002] The high-altitude automatic fire extinguishing device for electrical systems is an intelligent fire-fighting device specifically designed for high-altitude equipment in power systems. It can automatically detect, warn of, and extinguish electrical fires without human intervention, ensuring the safe operation of power facilities.

[0003] The existing authorization announcement number CN205127216U discloses a high-altitude electric automatic fire extinguishing device, including a fire extinguishing box. The bottom of the fire extinguishing box is connected to a utility pole via a support frame. The fire extinguishing box contains a fire extinguisher, the top of which is connected to the fire extinguishing box via a fixing device. The bottom of the fire extinguisher is equipped with a diverter. The surface of the diverter has four connection holes, and a spray pipe is threadedly connected to the connection holes. One end of the spray pipe is equipped with a nozzle. This high-altitude electric automatic fire extinguishing device can accurately and sensitively lock the fire location by setting a start line and extinguish the fire. By setting a diverter, even if multiple parts are on fire, it can effectively provide a timely fire extinguishing source to each spray pipe, which is convenient and fast. By setting a hollow ball, the fire extinguishing box is in a closed state when not in use. This device has a simple structure and can extinguish fire sources in a timely manner, preventing the occurrence of large-scale fires.

[0004] Existing high-altitude electric automatic fire extinguishing devices of this type have the following problems: when using high-altitude electric automatic fire extinguishing devices, the fire extinguishing coverage is limited, and they cannot extinguish fires from distant sources, resulting in poor performance. Therefore, we propose a high-altitude electric automatic fire extinguishing device. Utility Model Content

Both angle sensors 5 and 6 are bidirectionally electrically connected to the microcontroller 8. If the microcontroller 8 determines that a real fire has occurred, it will immediately initiate an automatic fire extinguishing process.The microcontroller 8 controls the operation of motor 479. The output shaft of motor 479 drives worm gear 478 to rotate. Worm gear 478 drives adapter block 41 to rotate through meshing worm wheel 477. Adapter block 41 drives rotary joint 42 to rotate, which in turn drives connecting pipe 43 to rotate horizontally. Angle sensor 5 is connected to the left end of worm gear 478, which detects the rotation angle in real time and feeds it back to microcontroller 8, forming a closed-loop control. At this time, solenoid valve 475 is closed, ensuring that connecting pipe 43 is accurately aligned with the horizontal position of the fire source. The extinguishing agent is driven by compressed inert gas to spray out from nozzle 46, achieving fire extinguishing of a small area of ​​fire source at the lower end of the fire extinguishing device. When a large-scale, long-distance fire source needs to be extinguished, microcontroller 8... The control motor 476 operates, and its output shaft drives the worm gear 474 to rotate.

[0024] The working principle of the high-altitude electric automatic fire extinguishing device provided by this utility model is as follows: When using the high-altitude electric automatic fire extinguishing device, first install the device in the designated position through the mounting plate 1. Then, connect the device to the pressure tank containing the fire extinguishing agent through the external pipe 3. Output is then achieved through the external pipe 3. Next, the fire source detection camera 7 collects image information of the surrounding environment in real time. When the fire source detection camera 7 detects a suspected fire, it transmits the image data to the microcontroller 8 in real time. The microcontroller 8 analyzes and identifies the data to confirm whether it is a real fire. If the microcontroller 8 determines that it is a real fire, it will immediately start the automatic fire extinguishing process. The microcontroller 8 controls the operation of the second motor 479. The output shaft of the second motor 479 drives the second worm gear 478 to rotate. The second worm gear 478 drives the adapter block 41 to rotate through the meshing worm wheel 477.

The angle sensor 5 is connected to the left end of the second worm gear 478 to detect the rotation angle in real time and feed it back to the microcontroller 8, forming a closed loop. In this control state, the solenoid valve 475 is closed, ensuring that the connecting pipe 43 is accurately aligned with the horizontal position of the fire source. The extinguishing agent is driven by compressed inert gas to spray out from the nozzle 46, achieving fire extinguishing of a small area of ​​fire source at the lower end of the fire extinguishing device. When a large-scale, long-distance fire source is to be extinguished, the microcontroller 8 controls the operation of the motor 476. The output shaft of the motor 476 drives the worm gear 474 to rotate. The worm gear 474 drives the rotating end of the rotary joint 44 to rotate through the meshing worm wheel 473, thereby driving the connecting pipe 43 to rotate. Pipe 2 45 rotates around rotary joint 2 44. Angle sensor 2 6 is connected to the left end of worm gear 1 474 to detect the pitch angle in real time and feed it back to microcontroller 8. After adjusting the position of connecting pipe 2 45, the solenoid valve 475 is opened by controlling microcontroller 8. Then, the extinguishing agent is driven by compressed inert gas to pass through rotary joint 1 42, connecting pipe 1 43, rotary joint 2 44 and connecting pipe 2 45, and finally sprayed out through nozzles 46 evenly distributed on the outer surface of both, thereby realizing fire extinguishing in a larger area.
