[0034] As an embodiment of the present invention, a hollow box 32 is fixedly connected to the left side of the shell 1, and a semiconductor refrigeration plate 22 is horizontally installed in the hollow box 32.

[0035] In the present invention, when in use, the staff takes three pieces of circular plate-shaped waterproof materials as samples, then opens the sealing door 31, places the waterproof materials on the three support rings 13, then closes the sealing door 31, starts the motor 6 to rotate forward, and the forward rotation of the motor 6 will be transmitted by the transmission belt 9 and the two pulleys 8, so that the two threaded rods 7 rotate synchronously, so that the lifting plate 11 moves downward synchronously, and the downward movement of the lifting plate 11 will use the fixed rod 15 to drive the U-shaped connecting rod 14 to drive the detection tube 12 to move downward until the lower end surface of the detection tube 12 completely contacts the waterproof material, and then the motor 6 is turned off;

[0038] After the detection is completed, multiple sealing doors 31 are opened, and then a water body detector is used to detect whether the lower end surfaces of multiple waterproof materials are leaking to determine the waterproofness of the materials. Subsequently, the sealing doors 31 are closed, and the motor 6 is started to rotate in the opposite direction, so that the lifting plate 11 can be moved up, and the detection cylinder 12 can be moved up. Then, the water will enter the water storage chamber 4 again through the water permeable port and the connecting port 3, and the water will be reused to improve the utilization rate of the water. The upward movement of the lifting plate 11 will move the piston rod and the piston block upward, and cooperate with the second one-way valve 29 to draw the water in the water storage chamber 4 into the inner bottom space of the piston cylinder 25.

[0041] Step 2: Check that the lower end surface of the tube 12 is completely in contact with the waterproof material and turn off the motor 6;

[0042] Step 3: Start the semiconductor cooling sheet 22 and the air pump 20, which will blow high-temperature air into the leftmost detection chamber 2 and blow low-temperature air into the rightmost detection chamber 2, so as to perform material testing at different temperatures, thereby improving the accuracy of the testing;

[0043] Step 4: After the detection is completed, open multiple sealing doors 31 to detect whether the lower end surfaces of multiple waterproof materials are leaking, then close the sealing doors 31, start the motor 6 to rotate in the reverse direction, then open the sealing doors 31, and remove the three waterproof materials.
