[0025] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0026] The utility model provides a fire hydrant water pressure detection device, comprising:

[0027] A water pipe 1, one end of which is used to connect to an external fire hydrant, and one end of the water pipe 1 is threadedly connected to the water outlet of the fire hydrant, so that they can communicate with each other;

[0028] The sleeve 2 has one end slidably mounted in the water pipe 1;

[0029] The pressure gauge 3 is arranged on the side wall of the sleeve 2 and is used to test the water pressure in the fire hydrant. The pressure gauge 3 is fixedly mounted on the side wall of the sleeve 2, and the detection end penetrates the side wall of the sleeve 2, so that the water pressure in the sleeve 2 can be detected. At the same time, the pressure gauge 3 can display the pressure, which is convenient for the staff to watch;

[0030] The water tank 4 is arranged on the surface of the water pipe 1. The water tank 4 is welded on the surface of the water pipe 1 and can store water in the water pipe 1 and the sleeve 2, and is used to store water in the fire hydrant;

[0031] The anti-impact device is arranged on the outer surface of the sleeve 2 and connected to the water pipe 1, and is used to reduce the impact of water in the fire hydrant on the sleeve 2.

[0032] Specifically, the anti-impact device includes:

[0033] The annular block 5 is arranged on the outer surface of the sleeve 2. The annular block 5 is welded to the outer surface of the sleeve 2 and can be relatively fixed;

[0034] The annular member 6 is sleeved on the outer surface of the sleeve 2;

[0035] The elastic member 7 is wound and installed on the outer surface of the sleeve 2, and its two ends are respectively connected to the annular block 5 and the annular member 6. The elastic member 7 is a compression spring. The two ends of the elastic member 7 are respectively welded to the two end surfaces of the annular block 5 and the annular member 6, so as to be relatively fixed.

[0036] There are two pairs of connecting frames 8, one end of which is connected to the surface of the water pipe 1 and the other end is connected to the outer surface of the ring 6. The two ends of the connecting frame 8 are respectively welded to the surface of the water pipe 1 and the surface of the ring 6, so that they can be relatively fixed.

[0037] Specifically, a water pump 9 is installed on the inner wall of the water tank 4, the water outlet end of the water pump 9 penetrates the side wall of the water tank 4, and is installed with a water valve 10. The water pump 9 is fixedly installed on the inner wall of the water tank 4, and the water valve 10 is fixedly installed on the water outlet end of the water pump 9. The staff opens the water valve 10 and starts the water pump 9 at the same time, so that the water in the water tank 4 can be pumped out;

[0038] The side wall of the water pipe 1 is connected with a connecting pipe 11, one end of the connecting pipe 11 penetrates the side wall of the water tank 4, and the two ends of the connecting pipe 11 are respectively connected with the water pipe 1 and the water tank 4, so that the water in the water pipe 1 can flow into the water tank 4;

[0039] An electromagnetic valve 12 is installed on the water pipe 1, and the electromagnetic valve 12 can block the connecting pipe 11. The staff can open the electromagnetic valve 12 to connect the connecting pipe 11, so that the water in the water pipe 1 flows into the water tank 4. Closing the electromagnetic valve 12 can close the connecting pipe 11 to prevent the water in the water pipe 1 from flowing into the water tank 4.

[0040] Specifically, an annular groove 13 is formed on the outer wall of the sleeve 2, and an O-ring 14 is installed in the annular groove 13. The outer surface of the O-ring 14 contacts the inner wall of the water pipe 1. The O-ring 14 can seal the gap between the water pipe 1 and the sleeve 2 to prevent water from seeping out.

[0041] Specifically, a limiting groove 15 is formed on the inner wall of the water pipe 1, and a limiting block 16 slidably connected to the limiting groove 15 is installed on the outer surface of the sleeve 2. The limiting block 16 is slidably installed in the limiting groove 15, which can limit the sleeve 2 and prevent the sleeve 2 from shaking.

[0042] Working principle: First, the staff connects one end of the water pipe 1 to the water outlet of the fire hydrant through a thread. At this time, the staff opens the fire hydrant to allow the water in the fire hydrant to flow into the water pipe 1 and the sleeve 2. At this time, the water flow impacts the sleeve 2, causing the sleeve 2 to move. At this time, the elastic member 7 is compressed, which can exert a force on the annular block 5, thereby reducing the impact of the water flow and preventing damage to the entire device. At this time, the pressure gauge 3 can detect the water pressure flowing out of the fire hydrant, which is displayed by the pressure gauge 3 for the convenience of the staff to record. After the detection is completed, the staff closes the fire hydrant and opens the solenoid valve 12 at the same time, so that the water in the water pipe 1 and the sleeve 2 flows into the water tank 4 from the connecting pipe 11, and then closes the solenoid valve 12 to store the water in the water tank 4. At this time, the staff opens the water valve 10 and starts the water pump 9 to pump out the water in the water tank 4, which is convenient for the staff to collect and reuse, thereby reducing the waste of water resources.
