Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Referring to Figures 1 to 3 , in the embodiments of the present utility model, an indoor fire-fighting water pipe water pressure detection device includes a base 1, a first support frame 2 fixedly connected to the base 1, a pressure chamber 3 fixedly connected to the first support frame 2, a second support frame 4 fixedly connected to the base 1, a water supply pipe 5 fixedly connected to the second support frame 4, one end of the water supply pipe 5 is fixedly connected to the pressure chamber 3, a one-way sealing assembly is arranged in the water supply pipe 5, the other end of the water supply pipe 5 is fixedly connected to a connector 6, a connecting pipe 7 is fixedly connected to the water supply pipe 5, a connecting seat 8 is fixedly connected to the connecting pipe 7, a water pressure gauge 15 is connected in the water supply pipe 5, a third support frame 19 is fixedly connected to the base 1, a force application pipe 20 is fixedly connected to the third support frame 19, a sliding sealing cylinder 16 is fixedly connected in the pressure chamber 3, a sliding connecting rod 17 is slidably connected in the sliding sealing cylinder 16, one end of the sliding connecting rod 17 is fixedly connected to a sliding piston plate 18, the sliding piston plate 18 is slidably connected to the inner wall of the pressure chamber 3, the other end of the sliding connecting rod 17 is fixedly connected to a driving plate 21, the driving plate 21 is slidably connected in the force application pipe 20, and a pressurizing assembly for pressurizing the force application plate 24 is connected to the driving plate 21. First, one end of the fire-fighting water pipe is connected to the connecting seat 8, and the other end of the fire-fighting water pipe is sealed. Then, water is injected into the connecting pipe 7 and the fire-fighting water pipe through the water supply pipe 5. After the water injection is completed, the water supply pipe 5 is sealed through the one-way sealing assembly. Then, the water in the pressure chamber 3 is pressurized through the pressurizing assembly, and the pressure acts on the fire-fighting water pipe through the water, so as to detect the pressure resistance of the fire-fighting water pipe, and the water pressure of the water is accurately read through the water pressure gauge 15.

[0019] In a case of this embodiment, please refer to Figures 1 to 3, the pressurizing assembly includes a threaded cylinder 22 fixedly connected inside the force - increasing pipe 20. A screw rod 23 is threadedly connected inside the threaded cylinder 22. One end of the screw rod 23 is rotatably connected to a force - increasing plate 24. The force - increasing plate 24 is slidably connected inside the force - increasing pipe 20. A second spring 25 is arranged between the force - increasing plate 24 and the driving plate 21. The other end of the screw rod 23 is fixedly connected to a crank 26. In the present utility model, by shaking the crank 26, the screw rod 23 is driven to rotate. The screw rod 23 drives the screw rod 23 to expand and contract through the threaded connection with the threaded cylinder 22. The screw rod 23 drives the force - increasing plate 24 to expand and contract, and then compresses the second spring 25 through the force - increasing plate 24. The second spring 25 then acts on the driving plate 21 with the pressure.

[0020] In one case of this embodiment, please refer to Figures 1 to 3 , a sliding groove 27 is arranged inside the force - increasing pipe 20. The driving plate 21 passes through the sliding groove 27 and is fixedly connected to a scale 28. The force - increasing plate 24 passes through the sliding groove 27 and is fixedly connected to a pointer 29. The pointer 29 cooperates with the scale 28. In the present utility model, the relative distance between the driving plate 21 and the force - increasing plate 24 is measured through the cooperation between the scale 28 and the pointer 29, and then the compressed distance of the second spring 25 is read. Finally, the driving force exerted by the second spring 25 on the driving plate 21 is accurately read through Hooke's law.

[0021] In one case of this embodiment, please refer to Figures 1 to 3 ,

[0022] In one case of this embodiment, please refer to Figures 1 to 3 , the one - way sealing assembly includes a sealing valve 9 fixedly connected inside the water supply pipe 5. A fixing frame 10 fixedly connected inside the water supply pipe 5 is arranged on one side of the sealing valve 9 close to the water inlet end of the water supply pipe 5. A sliding rod 11 is slidably connected inside the fixing frame 10. One end of the sliding rod 11 is fixedly connected to a sealing block 12. The sealing block 12 is arranged on the side of the sealing valve 9 away from the water inlet end of the water supply pipe 5. The sealing block 12 cooperates with the sealing valve 9. The other end of the sliding rod 11 is fixedly connected to a stop block 13. A first spring 14 sleeved on the sliding rod 11 is arranged between the stop block 13 and the fixing frame 10. When the present utility model injects water into the water supply pipe 5, first, as the water is injected, the water pressure inside the water supply pipe 5 gradually increases. Finally, the water pressure pushes the sealing block 12 to the side away from the sealing valve 9, thus opening the sealing valve 9. At this time, the water inside the water supply pipe 5 flows into the connecting pipe 7, thereby injecting water into the fire hose. After that, when the water in the pressurizing chamber 3 is pressurized, the water pressure in the connecting pipe 7 increases. At this time, the pressure difference pushes the sealing block 12 towards the side of the sealing valve 9, thus pressing the sealing block 12 tightly against the sealing valve 9, thereby sealing the water supply pipe 5, and further preventing the water inside the fire hose from flowing out along the water supply pipe 5 and affecting the detection result of the equipment.
