The water pressure in the water pipe 105 is monitored by the fire water pressure monitoring equipment 107. The liquid level in the fire water tank is monitored by the water level monitoring mechanism 3. The water pressure of the fire water pressure monitoring equipment 107 and the fire hydrant monitoring equipment 108 can be controlled respectively under the action of the valve body 106. Subsequently, the water inside the water tank body 1 can be discharged through the drain pipe 110.

[0034] When the water level inside the water tank body 1 changes, at this time, the frame 3032 is installed on the inner wall of the fire water pressure monitoring equipment 107 by screws. When the water level inside the water tank body 1 changes, the lifting float 301 moves up and down with the change of the water level inside the water tank body 1. When the lifting float 301 moves up and down, the lifting float 301 drives the adjusting rope 3033 to move on the surface of the guide roller 3031, and the adjusting rope 3033 is guided under the action of the guide roller 3031, and the guide roller 3031 is supported under the action of the frame 3032. When the water level inside the water tank body 1 decreases, the lifting float 301 drives the adjusting rope 3033 to move downward. At this time, the gravity block 302 drives the alarm plate to fit with the alarm on the upper inner wall of the water tank body 1. At this time, the upper alarm sounds an alarm, prompting the inside of the water tank body 1 The amount of water in the water tank body 1 is less. On the contrary, when the amount of water in the water tank body 1 increases, at this time, the lifting float 301 drives the adjusting rope 3033 to move on the surface of the frame 3032, and under the action of the adjusting rope 3033, the gravity block 302 is driven to move to fit with the alarm below the inner wall of the water tank body 1. At this time, the alarm below sounds an alarm to prompt that the amount of water inside the water tank body 1 has increased, so as to realize the water level monitoring function of the monitoring demonstration device, so that the monitoring demonstration device can monitor the amount of water inside the water tank body 1 when it is used, avoiding the phenomenon of excessive or insufficient water in the water tank body 1 during the use of the monitoring demonstration device.
