[0005] To address the aforementioned issues, we propose a high-rise fire extinguishing device. Utility Model Content

[0018] Example 1

[0019] like Figures 1 to 4As shown, this utility model discloses a high-rise fire extinguishing device. The technical solution includes a box body 1, a fire hose connector 2, and a fire hose reel 4. A box door 10 is rotatably installed on the front left side of the box body 1. A fire hose reel 4 is installed on the top of the rear end of the inner side of the box body 1. A fire hose connector 2 is installed on the bottom right side of the inner side of the box body 1, and the bottom of the fire hose connector 2 is connected to a water inlet pipe 9 installed below the box body 1. A water guide pipe 7 is connected to the bottom left side of the fire hose connector 2. A third electric valve 8 is installed on the water guide pipe 7. The other end of the water guide pipe 7 is connected to a detection unit 5 installed on the left side inside the box body 1. By opening the third electric valve 8, water from the bottom of the fire hose connector 2 is introduced into the detection unit through the water guide pipe 7. In unit 5, the detection unit 5 includes a pressure measuring tube 51, a piston rod 52, a piston plate 53, a pressure measuring rod 54, a compression spring 55, a pressure sensor 56, and a baffle 57. The pressure measuring tube 51 is fixedly installed inside the rear left side of the housing 1, and the bottom right side of the pressure measuring tube 51 is connected to the water guide pipe 7. The pressure measuring rod 54 is slidably installed on the top of the pressure measuring tube 51. The top end of the pressure measuring rod 54 passes through the through hole opened on the top of the pressure measuring tube 51 and is fixedly connected to the baffle 57. The compression spring 55 is fitted on the middle of the outer side of the pressure measuring rod 54. The pressure sensor 56 is fixedly installed at the center of the lower surface of the push plate at the bottom of the pressure measuring rod 54. A pointer 58 is set on the front side of the push plate at the bottom of the pressure measuring rod 54. The piston rod 52 is set below the pressure sensor 56, and the piston rod 52 is slidably installed. The piston rod 52 is installed in the guide hole in the middle of the pressure measuring tube 51. The upper and lower ends of the piston rod 52 are fixedly connected to the piston plates 53 that are slidably installed at the upper and lower ends inside the pressure measuring tube 51, respectively. It also includes a protective partition 11, which is fixedly installed inside the rear side of the housing 1. The protective partition 11 is located between the fire hose reel 4 and the pressure measuring tube 51. When the fire hose reel 4 is unfolded for use, the protective partition 11 isolates the detection unit 5 to avoid mechanical interference. A connecting plate 12 is welded to the left side of the protective partition 11, and a scale line 13 is provided on the front side of the connecting plate 12. Water is supplied to the inside of the pressure measuring tube 51 through the water pipe 7. The pressure of the water flow acts on the piston rod 52 and piston plate 53 inside the pressure measuring tube 51, pushing them to move upward. When the piston rod 52 moves upward, it pushes the pressure measuring rod 5. 4. The piston rod rises synchronously and compresses the compression spring 55. Meanwhile, the pressure sensor 56 at the bottom of the pressure measuring rod 54 captures the water pressure data in real time and transmits the electrical signal to the controller 3. At the same time, the pointer 58 at the top of the pressure measuring rod 54 moves with the piston rod 52, providing a visual pressure reading in conjunction with the scale line 13 on the connecting plate 12 to assist in manual verification. The bottom of the detection unit 5 is equipped with a return unit 6, which is connected to the middle of the water inlet pipe 9. The return unit 6 includes a water pump 61, a suction pipe 62, a first electric valve 63, a drain pipe 64, and a second electric valve 65. The water pump 61 is fixedly installed on the bottom left side of the inner side of the housing 1. The suction end of the water pump 61 is equipped with a suction pipe 62, and the other end of the suction pipe 62 is connected to the bottom of the pressure measuring tube 51.A first electric valve 63 is installed in the middle of the suction pipe 62. A drain pipe 64 is installed at the discharge end of the water pump 61. The other end of the drain pipe 64 is connected to the middle of the water inlet pipe 9. A second electric valve 65 is installed at the right end of the drain pipe 64. The controller 3 analyzes the data detected by the pressure sensor 56. When the pressure is normal, the controller 3 starts the water pump 61 and opens the first electric valve 63 and the second electric valve 65. The water pump 61 draws water from the bottom of the pressure measuring pipe 51 through the suction pipe 62 and returns the water to the water inlet pipe 9 through the drain pipe 64, forming a detection cycle. The system also includes a controller 3, which is located at the rear right end of the interior of the housing 1. The output of the controller 3 is electrically connected to the first electric valve 63, the second electric valve 65, the third electric valve 8, and the water pump 61. The input of the controller 3 is electrically connected to the pressure sensor 56 and the output of an external power supply.

[0020] The working principle of this utility model is as follows: When the device is started, the controller 3 controls the third electric valve 8 to open, allowing water from the bottom of the fire hose connector 2 to flow through the water guide pipe 7 into the pressure measuring tube 51 of the detection unit 5. At this time, the water pressure acts on the piston rod 52 and piston plate 53 inside the pressure measuring tube 51, pushing them upward. When the piston rod 52 moves upward, it pushes the pressure measuring rod 54 to rise synchronously and compresses the compression spring 55. Meanwhile, the pressure sensor 56 at the bottom of the pressure measuring rod 54 captures the water pressure data in real time and transmits the electrical signal to the controller 3. At the same time, the pointer 58 at the top of the pressure measuring rod 54 moves with the piston rod 52, providing a visual pressure reading in conjunction with the scale line 13 on the connecting plate 12 to assist manual verification. Then, the controller 3 analyzes the data detected by the pressure sensor 56. Analysis shows that when the pressure is normal, the controller 3 starts the water pump 61 and opens the first electric valve 63 and the second electric valve 65. The water pump 61 draws water from the bottom of the pressure measuring pipe 51 through the suction pipe 62 and returns the water to the inlet pipe 9 through the drain pipe 64, forming a detection cycle. When the pressure is abnormal, such as when the pressure is too low, the controller 3 triggers an alarm or links the fire protection system to prompt maintenance personnel to carry out maintenance. When a fire occurs, that is, when the user opens the valve on the fire hose connector 2, the controller 3 closes the third electric valve 8 to cut off the water flow in the water pipe 7, and at the same time closes the first electric valve 63 and the second electric valve 65 of the return unit 6. At this time, the fire hose connector 2 is supplied with full pressure, the fire hose reel 4 is unfolded and used, and the protective partition 11 isolates the detection unit 5 to avoid mechanical interference.
