[0050] The coupling 21 is arranged above the interior of the space, and the coupling 21 is used to connect the output end of the second motor 20 with the two sets of transmission shafts 22; the output end of the second motor 20 is connected to the input end of the coupling 21, and the model of the second motor 20 is selected according to actual needs and meets the working conditions; the two sets of transmission shafts 22 are symmetrically arranged on both sides of the coupling 21 and connected to the output end of the coupling 21; the two sets of second worms 23 are connected to the transmission shaft 22 and rotate with the transmission shaft 22; the two sets of second worm gears 24 is arranged on the edge of the second worm 23 and is meshed with the second worm 23. When the second worm 23 rotates, it will drive the second worm wheel 24 to rotate slowly; the two groups of second lead screws 25 are coaxially arranged with the two groups of second worm wheels 24 and rotate with the second worm wheel 24; the two groups of second lead screw nuts 26 are threadedly connected with the second lead screws 25, and the second lead screw nuts 26 are connected to the moving module 2 to drive the moving module 2 to move vertically. When the second lead screw 25 rotates, the second lead screw nut 26 will move upward or downward at the same time.

[0051] Start the second motor 20. The output end of the second motor 20 drives the two sets of transmission shafts 22 to rotate through the coupling 21. The two sets of transmission shafts 22 simultaneously drive the two sets of second worm gears 23 to rotate. The second worm gear 23 drives the second worm wheel 24 to rotate. The second worm wheel 24 simultaneously drives the second lead screw 25 to rotate. The second lead screw 25 will cause the second lead screw nut 26 to move vertically downward.

[0054] Specifically, the chassis 13 is arranged directly below the fixed plate 9 and connected to the fixed module 7; the specimen sleeve mold 10 is arranged between the fixed plate 9 and the chassis 13; the sealing sleeve 11 is arranged on the inner wall of the specimen sleeve mold 10 for sealing, and the concrete is placed inside the sleeve mold 10; the sealing gasket 12 is arranged between the specimen sleeve mold 10 and the chassis 13 for sealing the connection.

When the first worm 15 rotates, it will drive the first worm wheel 16 to rotate; the two groups of first lead screws 17 are coaxially arranged with the first worm wheel 16 and rotate with the first worm wheel 16; the two groups of first lead screw nuts 18 are respectively threadedly connected with the two groups of first lead screws 17. When the first lead screw 17 rotates, the first lead screw nut 18 will move horizontally; the two groups of locks 19 are connected to the first lead screw nuts 18 and move horizontally with the first lead screw nuts 18.

Since the thread directions of the two groups of first lead screws 17 are opposite, the two groups of first lead screw nuts 18 move toward the middle or outward at the same time, and the first lead screw nut 18 drives the lock 19 to move, so that the lock 19 is inserted into the through hole on the limit block 8, thereby fixing the mobile module 2 and the fixed module 7 together to prevent the mobile module 2 from shaking, which is convenient for use.

[0066] When the concrete impermeability tester is in use, first, the user places the concrete in the specimen sleeve mold 10 in sequence, and then starts the second motor 20. The output end of the second motor 20 drives the two sets of transmission shafts 22 to rotate through the coupling 21. The two sets of transmission shafts 22 simultaneously drive the two sets of second worms 23 to rotate. The second worms 23 drive the second worm gear 24 to rotate. The second worm gear 24 simultaneously drives the second lead screw 25 to rotate. The second lead screw 25 causes the second lead screw nut 26 to move vertically downward. The second lead screw nut 26 drives the moving module 2 to move. The moving module 2 simultaneously drives multiple fixed disks 9 to move, so that the fixed disks 9 are docked with the specimen sleeve mold 10, so as to achieve installation and sealing of multiple stations at the same time, making the operation more convenient. In this process, the sleeve mold 10 and the sealing gasket 12 are used to connect The sealing is performed at the place to realize the sealing assembly process to prevent omission during the measurement process. After the mobile module 2 moves to the bottom, the limit block 8 will be inserted into the mobile module 2. At this time, the first motor 14 is started, and the output end of the first motor 14 drives the first worm 15 to rotate. The first worm 15 also drives the first worm gear 16 to rotate slowly. The first worm gear 16 drives the two groups of first lead screws 17 to rotate in the same direction. Since the thread directions of the two groups of first lead screws 17 are opposite, the two groups of first lead screw nuts 18 move toward the middle or outward at the same time. The first lead screw nut 18 drives the lock 19 to move, so that the lock 19 is inserted into the through hole on the limit block 8, thereby fixing the mobile module 2 and the fixed module 7 together to prevent the mobile module 2 from shaking, making it easy to use, and completing the use of this device.
