The drive component includes a mounting plate 410 fixedly connected to the inner cavity of the rigid connecting pipe 3. A fixing sleeve 411 is fixedly connected to the outside of the mounting plate 410, and a spring is provided in the inner cavity of the fixing sleeve 411. 412, one end of the spring 412 is fixedly connected to the fixed sleeve 411, and the other end of the spring 412 is fixedly connected to the limiting plate 421. A movable rod 413 is fixedly connected to the outer side of the limiting plate 421. The movable rod 413 passes through the fixed sleeve 411 and is fixedly connected to a movable disc 414. A fixed ring 415 is movably connected to the outer side of the movable disc 414. The fixed ring 415 is fixedly connected to the rigid connecting pipe 3.

[0018] By setting up a water pressure monitoring component 4, the movable plate 414 can move under water pressure during firefighting operations, thereby enabling the device to automatically control the rotation of the shaft 45. This allows the device to display the water pressure on the dial 42, making it easier for firefighters to know the water pressure in a timely manner and improving the effectiveness of the device.

[0019] The water pressure compensation component 5 includes two bearing brackets 51 fixedly connected to the inner wall of the connecting box 1. A rotating rod 52 is rotatably connected between the two bearing brackets 51. The top end of the rotating rod 52 passes through the bearing bracket 51 and is connected to a transmission component. A first thread 53 and a second thread 54 are provided on the outer side of the rotating rod 52. The threads of the first thread 53 and the second thread 54 are in opposite directions. A movable seat 55 is threadedly connected to the outer side of both the first thread 53 and the second thread 54. A pressing plate 56 is fixedly connected to the outer side of the movable seat 55. A guide seat 57 is fixedly connected to the side of the pressing plate 56 away from the movable seat 55. A guide rod 58 is slidably connected to the inner cavity of the guide seat 57. Both ends of the rod 58 are fixedly connected to the fixed seats 59, which are fixedly connected to the connecting box 1.

One end of the mounting shaft 511 is rotatably connected to the connecting box 1, and the other end of the mounting shaft 511 passes through the bearing bracket 51 and is fixedly connected to the rotating rod 52.

[0020] By setting up a water pressure compensation component 5, the device can automatically control the rotating rod 52 to rotate when abnormal water pressure is detected, so that the two squeezing plates 56 can move towards each other, so that the two squeezing plates 56 can squeeze or relax the flexible connecting pipe 2 to compensate for the water pressure, thereby avoiding a reduction in the fire-fighting effect of the device due to abnormal water pressure.

[0021] The fire alarm component 6 includes a mounting base 61 fixedly connected to the outside of the connecting box 1. A response element 62 is rotatably connected below the mounting base 61. A striking element 63 is disposed below the response element 62. A mounting rod 64 is fixedly connected to the outside of the striking element 63. The mounting rod 64 is rotatably connected to the connecting box 1, and a gear 65 is fixedly connected to the outside of the mounting rod 64. A rack 66 meshes with the outside of the gear 65. A linkage component is disposed below the rack 66. The linkage component includes a fixing plate 68 fixedly connected to the outside of the connecting box 1. A connecting frame 67 is slidably connected above the fixed plate 68. A rack 69 is fixedly connected to both the upper and lower inner walls of the connecting frame 67. A residual gear 610 meshes between the two racks 69. A linkage rod 611 is fixedly connected to the outer side of the residual gear 610. The linkage rod 611 passes through the connecting box 1 and is fixedly connected to a driven conical wheel 612. A driving conical wheel 613 meshes with the outer side of the driven conical wheel 612. A fixed shaft 614 is fixedly connected to the outer side of the driving conical wheel 613. The fixed shaft 614 passes through the bearing bracket 51 and is fixedly connected to the rotating rod 52.

[0022] By setting up the fire alarm component 6, when the device compresses or releases the flexible connecting pipe 2 to compensate for water pressure, it can automatically control the rotation of the residual gear 610. This allows the device to control the striking element 63 to rotate back and forth continuously, so that the device can continuously strike the response element 62, thereby alerting firefighters that the water pressure is abnormal. This facilitates firefighters in taking appropriate measures, improving the practicality of the device.

[0023] Working principle of the invention: When the device is needed, connect the flexible connecting pipe 2 to the fire hydrant. The water in the fire hydrant will then pressurize the movable plate 414, separating it from the fixed ring 415, thus facilitating normal operation of the device. When the movable plate 414 moves, it drives the connecting plate 416, which is fixedly connected to it, to move synchronously. This, in turn, causes the connecting plate 416 to drive the movable plate 417, which is fixedly connected to it, to move synchronously. The movable plate 417, in turn, drives the rack 418, which is fixedly connected to it, to move synchronously. The gear 420 meshing with it rotates, and when the gear 420 rotates, it drives the connecting rod 49 fixedly connected to it to rotate, which in turn drives the driving wheel 48 fixedly connected to it to rotate. When the driving wheel 48 rotates, it drives the driven wheel 46 to rotate through the belt 47, which in turn drives the rotating shaft 45 fixedly connected to it to rotate. When the rotating shaft 45 rotates, it drives the pointer 44 fixedly connected to it to rotate. When the water pressure is normal, the pointer 44 will point to the designated position on the dial 42. When the water pressure is abnormal, the pressure on the movable disc 414 will increase or decrease. At this time, the driven wheel 46 will rotate. When the driven wheel 46 rotates, it will drive the linkage shaft 515 fixedly connected to it to rotate. This will cause the linkage shaft 515 to drive the driving wheel 514 fixedly connected to it to rotate. When the driving wheel 514 rotates, it will drive the driven wheel 512 to rotate through the belt 513. This will cause the driven wheel 512 to drive the mounting shaft 511 fixedly connected to it to rotate. When the mounting shaft 511 rotates, it will drive the rotating rod 52 fixedly connected to it to rotate. This will cause the rotating rod 52 to drive the threaded wire 53 and the threaded wire 54 to rotate synchronously. Since the threaded wires 53 and 54 are in opposite directions, the two movable seats 55 will move towards each other. When the movable seats 55 move, they will drive the pressing plate 56 fixedly connected to them to move synchronously. This will cause the pressing plate 56 to press or release the flexible connecting pipe 2, thereby compensating for the water pressure during use. When the rotating rod 52 rotates, it drives the fixed shaft 614, which is fixedly connected to it, to rotate. This causes the fixed shaft 614 to drive the driving cone wheel 613, which is fixedly connected to it, to rotate. The driving cone wheel 613, in turn, drives the driven cone wheel 612, which in turn drives the linkage rod 611, which is fixedly connected to it, to rotate. The linkage rod 611, in turn, drives the residual gear 610, which is fixedly connected to it, to rotate. This causes the residual gear 610, under the action of the upper and lower racks 69, to drive the connecting frame 67 to move left and right continuously. When the connecting frame 67 moves, it drives the rack 66, which is fixedly connected to it, to move synchronously. This causes the rack 66 to drive the gear 65, which is fixedly connected to it, to rotate. When the gear 65 rotates, it drives the mounting rod 64, which is fixedly connected to it, to rotate. This causes the mounting rod 64 to drive the striking element 63, which is fixedly connected to it, to swing back and forth continuously. When the striking element 63 swings, it strikes the responding element 62, thereby alerting firefighters that the water pressure is abnormal so that they can take appropriate measures.
