The capillary rope 5 is made of hemp ropes, the hemp ropes are soaked in pine oil for 48 hours in advance, the hemp ropes have good water absorption effect, the main reason for water absorption is that tiny capillary spaces exist among all filaments in the hemp ropes, and the linearity of the capillary spaces is small enough to be close to the curvature radius of a liquid meniscus, so that the capillary phenomenon is caused, the capillary effect can be weakened by increasing the size of the capillary spaces among the filaments, namely, the water quantity of water conducted to the water seepage layer 2 through the hemp ropes is reduced;

the gear 4 is positioned on one side of the capillary rope 5 close to the water seepage layer 2, the hard rod between the piston 7 and the rack 3 is a straight rod, and the gear 4 is higher than the overflow hole 9, namely, the gear 4 is rarely submerged by water in use, so that the corrosion degree of the part of the structure of the gear 4 and the rack 3 in use is reduced, and the service life of the whole brick body is prolonged.
