[0036] Working principle: When monitoring the seepage pressure of a high earth-rock dam, the water level gauge 5, the electromagnetic valve 6 and the air pump 7 are controlled by connecting the relevant monitoring terminal and the connecting line 2. Under the action of the water level gauge 5, the water level in the water storage tank 1 is detected. Under the action of the electromagnetic valve 6, the pressure relief in the water storage tank 1 is controlled. When it is necessary to pressurize the inside of the water storage tank 1, the air pump 7 is started. Under the action of the air pipe 71, the pressure in the water storage tank 1 is changed. When the pressure in the water storage tank 1 exceeds the design requirement, under the connection between the fixed plate 8 and the support column 81, the connection between the connecting sleeve 82 and the telescopic spring 83 changes the ball 84 in the sleeve 85. The position inside achieves the effect of autonomous pressure relief. Under the connection between the water storage tank 1 and the liquid inlet pipe 11, through the connection between the first liquid guide cover 13 and the sliding sleeve 14, and the connection between the sliding sleeve 14 and the second liquid guide cover 15, when the external water enters the water storage tank 1, the guide rod 9 and the guide ball 91 change their positions. At this time, the guide ball 91 and the second liquid guide cover 15 are not in contact, and the water enters the water storage tank 1. When the water in the water storage tank 1 is drained, the air pump 7 is started to change the pressure in the water storage tank 1. At this time, under the action of the support spring 97, the position of the control ball 98 is changed to open the liquid outlet groove 94 channel, thereby achieving the operation effect of draining water from the water storage tank 1.
