The principle of operation of the present invention will now be described as follows: when the air tightness detection is required to be carried out on the produced waterproof paint, the produced waterproof paint is firstly uniformly coated on the plastic air-permeable film 17, after the waterproof paint on the plastic air-permeable film 17 is solidified, the shell 3 is opened through the handle 28 and the hinge 2, the plastic air-permeable film 17 is placed on the opening above the detection box 1, then the shell 3 is placed down, the side wall at the lower end of the shell 3 is clamped above the plastic air-permeable film 17, the joint of the shell 3 and the detection box 1 is tighter by utilizing the shell 3 and the sealing rubber pad 27 arranged on the outer wall of the detection box 1, then the air pump 42 is started, air is introduced into the vacuum shell 41 through the air inlet pipe 44, the first piston 43 moves upwards, the air above the vacuum shell 41 is compressed, the air in the detection box 1 is compressed through the air outlet pipe 45, when the air pump 42 is used for introducing air into the vacuum shell 41, the air also enters the water storage tank 5 through the connecting pipe 46, the second piston 6 is pushed to move upwards, the water level in the water storage tank 5 rises, water in the water storage tank 5 enters the shell 3 through the water inlet pipe 18 and through holes formed in the side wall of the shell 3, the water stays above the plastic air-permeable film 17, the air pressure in the detection box 1 is continuously increased under the continuous pushing of the first piston 43, and when the air tightness of the waterproof paint is poor, the air passes through the plastic air-permeable film 17 and the waterproof paint to enter the water above the waterproof paint, so that bubbles are generated in the water, and a worker can intuitively observe the air tightness of the waterproof paint by observing the bubble change of the water in the shell 3;
After the air tightness of the waterproof paint is detected, the air pump 42 is used for pumping air in the vacuum shell 41, the first piston 43 moves downwards, the second piston 6 moves downwards under the action of the connecting pipe 46, when the second piston 6 moves upwards to enable water in the water storage tank 5 to enter the shell 3, the first rack 7 is driven to move upwards, the second driving bevel gear 15 is driven to rotate, the second driven bevel gear 14 is driven to drive the threaded screw 9 to rotate, the movable sliding block 10 moves downwards, the telescopic rod 13 is driven to move downwards, in the process of moving downwards the telescopic rod 13, because the elastic coefficient of the spring inside the telescopic rod 13 is larger than that of the connecting spring 11, in the process of moving downwards the telescopic rod 13, the length of the output end of one end of the telescopic rod 13 is not shortened, the elastic force of the connecting spring 11 is overcome, the side plate 12 moves downwards, in the process that the side plate 12 continuously moves downwards, when the connecting spring 11 cannot be compressed, one end output end of the telescopic rod 13 continuously moves downwards and stretches towards the inside of the telescopic rod 13, in the process that the second piston 6 moves downwards, the first rack 7 is driven to move downwards, the second drive bevel gear 15 drives the second driven bevel gear 14 to rotate reversely, the threaded screw 9 is driven to rotate reversely, the moving slide block 10 is driven to move upwards, in the process that the moving slide block 10 moves upwards, one end output end of the telescopic rod 13 continuously stretches out, after the output end of the telescopic rod 13 extends out of the telescopic rod 13, the side plate 12 is driven to move upwards continuously, when the second piston 6 reaches the inner wall of the lower end of the water storage tank 5, at the moment, gas in the detection box 1 is rapidly extracted by the first piston 43, in the process that the telescopic rod 13 drives the side plate 12 to move upwards continuously, the second rack 163 is driven to move, the first driving bevel gear 162 is driven to rotate, the first driven bevel gear 165 is driven to rotate, the supporting rod 164 is driven to rotate the belt pulley 166, the screw 168 is driven to rotate through the driving belt 171, the moving plate 169 which is sleeved on the outer wall of the screw 168 in a threaded manner is driven to move downwards, the pressing plate 170 is driven to move downwards, pressure is applied to water above the plastic breathable film 17, the water is downwards pressed, a worker can detect whether the waterproof property of the waterproof paint is good by observing whether water seeps out below the plastic breathable film 17, after the air tightness of the waterproof paint is detected, the waterproof property of the waterproof paint can be directly detected continuously, the detection working efficiency is improved, after the air in the detection box 1 is extracted, the waterproof property of the waterproof paint is detected through the driving of the second piston 6, the air pressure in the detection box 1 is prevented from being equal to the downward pressure of the pressing plate 170, the waterproof paint on the plastic breathable film 17 cannot permeate to the lower side when the upper pressure is applied, the waterproof paint is detected, the waterproof property is detected accurately, and the use effect of the device is improved;
In the process of upward movement of the second piston 6, the clamping block 26 is driven to move upward, when the clamping block 26 passes through the clamping plate 19, when the grooves 20 on two sides of the clamping block 26 are opposite to the clamping rods 22, the clamping rods 22 can be clamped into the grooves 20 under the action of the first springs 23 and the second springs 21, the water inlets of the water inlet pipes 18 are blocked by the clamping block 26, when the second piston 6 moves downward, the clamping rods 22 and the clamping block 26 are firmly clamped at the moment, the upper self-adhesive strip 25 and the lower self-adhesive strip 24 are separated by pulling force, the water inlets of the water inlet pipes 18 can be always blocked by the clamping block 26, water in the shell 3 is prevented from being extracted in the process of downward movement of the second piston 6, the subsequent detection of the waterproof paint is affected, and the stability and the practicability of the device are improved.
