[0016] The following specifically describes the specific embodiments of the present utility model with reference to the drawings.

[0017] Embodiment:

[0018] Combined with the drawings, the specific embodiment of a water level and pressure detection and control fire hydrant of the present utility model is shown as Figure 1, which mainly includes a fire hydrant body 1. On one side of the fire hydrant body 1, there is a pressure detection device 2. The pressure detection device 2 includes a pressure sensor 2a arranged inside the fire hydrant body 1 and a pressure gauge 2c connected to the pressure sensor 2a through a data line 2b. The pressure gauge 2c is installed on the fire hydrant body 1 through a mounting plate 2d.

[0019] On the other side of the fire hydrant body 1, there is a horizontal pipe 3 communicating with the internal space, and a pressure relief device 4 is arranged inside the horizontal pipe 3. Figure 2 , the pressure relief device 4 includes a pressure - actuated moving block 4a. At the right end of the pressure - actuated moving block 4a, there are two connecting plates 4b connected, and at the left end, there are two bottom rods 4c. On both of the two bottom rods 4c, there is a radially outward - protruding convex part 4d. At the bottom of the horizontal pipe 3, there are two slots 3c. Inside the two slots 3c, two springs 3d are respectively installed. The two springs 3d are respectively sleeved on the two bottom rods 4c, and the other end of the spring 3d is connected to the convex part 4d.

[0020] There are two pressure relief holes 3a, one above and one below, on the horizontal pipe 3. At each pressure relief hole 3a, there is a sealing plate 3b for blocking or opening the pressure relief hole 3a. One end of the sealing plate 3b is rotatably installed on a rotating rod 6. The rotating rod 6 is installed on the inner wall of the horizontal pipe 3 through a connecting plate 7. At the other end of the sealing plate 3b, there is a convex column 8. A vertical groove 9 is opened on the connecting plate 4b, and the convex column 8 can be slidably installed in the vertical groove 9. In this embodiment, the convex column 8 penetrates into the vertical groove 9, and the end size of the convex column 8 is larger than the groove width of the vertical groove 9, so that the convex column 8 can be connected to the connecting plate 4b.

[0021] On the horizontal pipe 3, there is also an adjusting mechanism 5 for adjusting the moving stroke of the pressure - actuated moving block 4a. At the bottom of the horizontal pipe 3, there are two accommodating cavities 3e corresponding to and communicating with the two slots 3c one by one. The other end of the accommodating cavity 3e is open to the outside. The adjusting mechanism 5 includes a top rod 5a threadedly connected to the bottom of the accommodating cavity 3e. The top rod 5a can penetrate into the slot 3c and abut against the bottom rod 4c.

[0022] In this embodiment, not shown in the figure, on the fitting surface where the sealing plate 3b fits with the pressure relief hole 3a, there is a sealing gasket to ensure the sealing performance.

[0023] When the fire hydrant of the present utility model is in use, the water pressure inside the hydrant can be directly read through the pressure gauge 2c. If it is confirmed that there is water, it can be directly used, improving the rescue speed. When the pressure inside the fire hydrant is too high, the pressure - actuated moving block 4a is pressed and moves leftward, the spring 3d is compressed, the connecting plate 4b is driven to move leftward, the convex column 8 slides downward along the vertical groove 9, the sealing plate 3b rotates around the rotating rod 6, and the pressure relief hole 3a is opened. As Figure 3 shown, after releasing a certain amount of pressure, the spring 3d resets, and the pressure relief hole 3a automatically closes. When the adjusting mechanism 5 is in use, by screwing the top rod 5a so that it extends into the slot 3c and abuts against the bottom rod 4c, the opening degree of the pressure relief hole 3a can be controlled, or the pressure relief function can be directly turned off (as Figure 4as shown in the figure), to meet the use of fire hydrants in various scenarios.
