The utility model has the advantages of automatically monitoring water pressure and preventing water theft through the coordinated use of a wireless signal transceiver module, a plug body, a pressure gauge, an alarm, a threaded barrel, a threaded column, a cavity, a water pressure sensor, a single-chip microcomputer, a sealing plug, a sealing ring, a speed sensor, a bearing, a remote terminal and a power-off switch, thereby solving the problem that the existing fire hydrants are not intelligent enough, cannot automatically monitor the water pressure in the hydrant, cannot issue an alarm when the water pressure is too high, and do not have the function of preventing water theft.

[0004] Existing smart fire hydrants have poor sealing effects during use. When left outdoors for a long time without being used, excessive internal water pressure may cause the fire hydrants to leak or even burst. When a fire occurs, the fire hydrants cannot be used to extinguish the fire in a timely and effective manner, causing incalculable casualties and property losses.

[0005] Therefore, in order to solve the above problems, a multi-sealed anti-damage intelligent fire hydrant is proposed. Utility Model Content

The sealing effect is good, which prevents the fire hydrant from leaking or even bursting due to excessive water pressure or too long time.

[0016] 2. The utility model fixes the water stop block by means of the first semicircular ring and the second semicircular ring which are fixedly connected to the inner wall of the water outlet pipe. When water flows through the water inlet, the water flow will squeeze the water stop block, so that the side of the water stop block will tightly squeeze the first semicircular ring and the second semicircular ring to block the outflow of water. The threaded rod is rotated to drive the water stop block to rotate, and water will flow out. The sealing effect is good, which can prevent excessive water pressure from causing water to penetrate into the outlet pipe and cause the outflow of fire water resources.

[0031] Working principle and process:

[0032] When installing the smart fire hydrant, the staff screws the upper part of the bolt body 1 to the top cover 14, the lower outer side of the bolt body 1 is fixedly connected to the first flange 2, the bottom end of the first flange 2 fits with the second flange 3, the first flange 2 and the second flange 3 are connected together by bolts, and under the action of the first gasket 22, the connection is tighter and does not cause liquid to flow out. The inner wall of the second flange 3 is fixedly connected to the water inlet pipe 4, and the inner wall of the water inlet pipe 4 is screwed with a valve core 5, which will block the water. If the water pressure is too high or the water seeps into the water due to disrepair, the valve core 5 will block the water. Inside the plug body 1, the surface of the ball core 7 spirally connected to the valve stem 6 fits tightly with the inner wall of the plug body 1. Under the action of the second gasket 23, the connection is made tighter to prevent the leaked water from flowing out and increase the sealing of the device. If the leaked water can enter the outlet pipe 8 through the ball core 7, because the inner wall of the water pipe is fixedly connected with the first semicircular ring 10 and the second semicircular ring 11, the water stop block 13 is fixed. When the water flows through the outlet pipe 8, the water flow will squeeze the water stop block 13, so that the side of the water stop block 13 tightly squeezes the first semicircular ring 10 and the second semicircular ring 11 On one side, the outflow of water is blocked, and the three-layer sealing blockage eliminates the possibility of water leakage caused by high water pressure and disrepair of fire hydrants. The sealing effect is good. When a fire hydrant is needed, the staff can quickly lock the position of the fire hydrant around the fire through the locator 16 fixedly connected in the square groove 15 inside the top cover 14, which is convenient for finding the nearest fire hydrant and quickly solving the fire, reducing the damage caused by the fire. The solar panel 21 fixedly connected to the upper surface of the top cover 14 will store the generated electricity in the battery 20 to prevent the fixed Because the positioner 16 has been without electricity for a long time, it is not convenient for the staff to quickly locate the fire hydrant. After that, the second hand wheel 25 is turned to drive the valve stem 6 to rotate, and drive the ball core 7 and the valve core 5 to move upward, so that water flows into the hydrant body 1, and the water flows into the square groove 15 through the circular hole 17 at the bottom end of the square groove 15, squeezing the pressure sensor 18, so that the staff can know the water pressure and change the water pressure to a pressure suitable for fire extinguishing, and then the first hand wheel 24 is turned to drive the threaded rod 12 to rotate, and the threaded rod 12 drives the water stop block 13 to rotate an angle, so that water flows out.
