[0035] The present application is further described in detail below in conjunction with the accompanying drawings.

[0036] See also Figure 1 and Figure 2 , is a fire water pressure detection alarm structure disclosed in an embodiment of the present application, comprising a connecting pipe 1, both ends of the connecting pipe 1 are used to connect fire pipes, a pressure test pipe 2 is fixedly connected to the middle of the connecting pipe 1, the pressure test pipe 2 is installed perpendicular to the connecting pipe 1, a pressure bearing plate 31 is slidably installed in the pressure test pipe 2, one end of the pressure test pipe 2 away from the connecting pipe 1 is threadedly connected to a pressure regulating screw 32, a pressure regulating spring 33 is installed between the pressure bearing plate 31 and the pressure regulating screw 32, a stabilizing rod 34 is fixedly connected to the pressure bearing plate 31, the other end of the stabilizing rod 34 passes through the pressure regulating spring 33 and is slidably installed in the pressure regulating screw 32, a trigger member 41 is fixedly installed on the stabilizing rod 34, a first switch 42 is fixedly installed on the pressure test pipe 2, the first switch 42 is located between the trigger member 41 and the pressure bearing plate 31, the first switch 42 is connected to a first alarm 43, a scale hole 201 is opened on the side of the pressure test pipe 2, and a pointer 341 is provided on the stabilizing rod 34, and the pointer 341 is slidably set in the scale hole 201.

[0037] Specifically, a pressure-bearing plate 31 and a stabilizing rod 34 are slidably connected to the pressure-adjusting screw 32, and a pressure-adjusting spring 33 is provided. The water pressure on the pressure-bearing plate 31 is balanced by the pressure-adjusting spring 33, and when the water pressure is less than the pressure of the pressure-adjusting spring 33, the first switch 42 is triggered by the trigger member 41 to cause the first alarm 43 to sound an alarm.

[0038] In this way, by adjusting the pointer 341 to indicate a suitable pressure, an alarm is issued when the pressure does not meet the standard, and the water pressure is monitored in real time.

[0039] In some feasible embodiments, the connecting pipe 1 is a pipe with interface-shaped ends to facilitate connection to a fire-fighting pipe. The pressure test tube 2 is in the shape of a circular tube. The pressure-bearing plate 31 is sealingly and slidingly connected to the pressure test tube 2. To facilitate the sealing of the pressure-bearing plate 31, a plurality of sealing grooves are axially arranged on the outer side of the pressure-bearing plate 31, and a sealing ring 311 is installed in the sealing groove. The trigger member 41 is in the shape of a circular ring, the stabilizing rod 34 is a cylindrical rod, and the pressure-adjusting spring 33 is installed between the trigger member 41 and the pressure-adjusting screw 32. To prevent the pressure-bearing plate 31 from popping out of the pressure test tube 2 due to the pressure of the pressure-adjusting spring 33, a retaining ring is provided near one end of the pressure test tube 2 near the connecting pipe 1, and a sealing plate is fixedly arranged on the pressure test tube 2, and the pressure-adjusting screw 32 is threadedly connected to the sealing plate.

[0040] The following is a further introduction based on specific usage scenarios.

[0041] When in use, the trigger member 41 is pressed against the first switch 42, and the pressure regulating screw 32 is rotated to make the pointer 341 point to the appropriate scale. When the water pressure is greater than the preset water pressure, the pressure-bearing plate 31 is lifted up, so that the first switch 42 disconnects the first alarm 43. When the water pressure is less than the preset water pressure, the pressure regulating spring 33 makes the trigger member 41 press against the first switch 42 to connect the first alarm 43.

[0042] As a specific implementation of a fire water pressure detection alarm structure provided in the application, a second switch 44 is slidably installed on the pressure test tube 2, and the second switch 44 is threadedly connected with a fixing screw 441. The second switch 44 is installed on the side of the trigger member 41 away from the first switch 42, and the second switch 44 is connected to the first alarm 43.

[0043] In general, excessive water pressure in the fire-fighting pipeline may also cause partial fire damage. By setting a second switch 44, the second switch 44 is set above the trigger member 41. When the water pressure is too high, the trigger member 41 moves upward to the second switch 44 to trigger the first alarm 43.

[0044] In some feasible embodiments, a rectangular hole is opened on the side wall of the pressure test tube 2, and rectangular plates are arranged on both sides of the rectangular hole. The rectangular plates are connected by fixing screws 441, and the second switch 44 is installed on the rectangular plates. A slidable pressure test tube 2 is provided to facilitate the adjustment of the maximum warning water pressure.

[0045] As another specific implementation of a fire water pressure detection alarm structure provided in the application, two electrodes 51 are fixedly installed on the inner side of the connecting pipe 1 , and the electrodes 51 are connected to a second alarm 52 .

[0046] In combination with specific usage scenarios, by setting the electrode 51, when water enters the connecting pipe 1, the electrode 51 is conducted by the water, and an early warning is issued through the second alarm 52. An early warning is issued after the sealing of the pressure-bearing plate 31 fails, which is convenient for its maintenance and replacement.

[0047] Furthermore, an insulating mesh tube longer than the electrode 51 is sleeved on the outer side of the electrode 51 .

[0048] It should be understood that by providing the insulating mesh tube, the possibility of the electrode 51 being mistakenly triggered by other metal parts is reduced.

[0049] In some feasible embodiments, the insulating mesh tube is a plastic tube with mesh holes arranged on the side.

[0050] As a specific implementation of a fire water pressure detection alarm structure provided in the application, a trigger member 41 is fixedly connected to a protective tube 61 near one end of the pressure regulating screw 32. The protective tube 61 is sleeved on the outside of the pressure regulating spring 33. The protective tube 61 can be slidably sleeved on the pressure regulating screw 32, and grease is arranged in the protective tube 61.

[0051] In combination with specific usage scenarios, the pressure-adjusting spring 33 needs to be kept in a compressed state. By providing a protective tube 61 and grease, the pressure-adjusting spring 33 is protected to reduce oxidation corrosion of the pressure-adjusting spring 33 and increase its service life.

[0052] Furthermore, a grease-draining hose 62 is installed at the bottom of the protection tube 61 , and one end of the grease-draining hose 62 away from the protection tube 61 is connected to the outside of the pressure test tube 2 .

[0053] It should be understood that when the pressure-adjusting spring 33 is compressed, the space inside the protective tube 61 is compressed. By providing the grease discharge hose 62 , excess grease is discharged during compression, thereby reducing the impact of the compression of the pressure-adjusting spring 33 .

[0054] Furthermore, a grease injection hose 63 is fixedly installed on a side of the protection tube 61 away from the grease discharge hose 62 , and an end of the grease injection hose 63 away from the protection tube 61 is connected to the outside of the pressure test tube 2 .

[0055] It should be understood that by providing the grease injection hose 63, it is convenient to regularly replace the grease.

[0056] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
