[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

[0027] Please refer to the following for details. Figure 1-4 A bottom drive device for an anti-permeability meter includes a frame 1 and a drive device. The drive device is located at the bottom of the frame 1, so that when the drive device is maintained, repaired or replaced, the staff does not need to climb to the top of the equipment to work, which eliminates safety hazards and avoids unnecessary damage to the equipment.

[0028] Specifically, the drive device includes a motor 2, a first synchronous pulley 3, two second synchronous pulleys 4, a belt 5, and two lead screws 6. The motor 2 is a geared motor 2, and its output shaft is connected to the first synchronous pulley 3. The two second synchronous pulleys 4 are respectively located on both sides of the frame 1. The belt 5 is sleeved on the first synchronous pulley 3 and the second synchronous pulley 4 and is used to connect the first synchronous pulley 3 and the second synchronous pulley 4. The two lead screws 6 are respectively located on both sides of the frame 1. One end of the lead screw 6 is connected to the second synchronous pulley 4, and the other end of the lead screw 6 passes through several layers of partitions 7 and is connected to the top of the frame 1. The topmost partition 7 is fixed with a lead screw 6 sleeve that is compatible with the lead screw 6.

[0029] It should be noted that: a test mold sleeve is fixed at the bottom of the partition 7 and a test mold pad is fixed at the top of the partition 7. The test mold sleeve and the test mold pad can be interlocked to form a sealed cavity for testing the impermeability of concrete test blocks. Each adjacent partition 7 is connected by a self-locking device. The self-locking device can unlock each layer of partition 7. The above technical means are all existing technologies, so they will not be described in detail.

[0030] Based on the above technical means: the motor 2 drives the first synchronous pulley 3 to rotate, which in turn drives the belt 5 to move, thereby driving the second synchronous pulley 4 to rotate. As a result, the lead screw 6 will also rotate, thereby driving the top partition 7 to rise and fall, so as to realize the separation or synchronous lifting of the upper partition 7 relative to the lower partition 7.

[0031] Furthermore, the drive device also includes two tensioning idler pulleys 8, which are located between the first synchronous pulley 3 and the second synchronous pulley 4 and can tension the belt 5 to ensure that the belt 5 does not come off the synchronous pulley.

[0032] Furthermore, the bottom of the frame 1 is equipped with two tensioning wheel adjustment mechanisms, which can adjust the position of the tensioning idler wheel 8.

[0033] Specifically, the tensioning wheel adjustment mechanism includes a tensioning mounting plate 16, a tensioning top plate 9, two first fasteners 10, two second fasteners 11, and a tensioning adjustment plate 12. The tensioning mounting plate 16 is fixed to the bottom of the frame 1, and the tensioning top plate 9 is fixed on the tensioning mounting plate 16. The first fasteners 10 are set on the tensioning top plate 9, and one end abuts against the tensioning adjustment plate 12. The tensioning adjustment plate 12 has two waist-shaped grooves 15. The second fasteners 11 are inserted into the waist-shaped grooves 15 and fixed on the tensioning mounting plate 16. The tensioning idler wheel 8 is set on the tensioning adjustment plate 12 of the tensioning wheel adjustment mechanism.

[0034] Based on the above technical means: when it is necessary to adjust the tension idler wheel 8, loosen the second fastener 11 slightly. At this time, the tension adjustment plate 12 and the tension idler wheel 8 can be moved. After the adjustment is completed, the first fastener 10 is used to abut against the tension adjustment plate 12. After abutting, the second fastener 11 is tightened. By fine-tuning the tension idler wheel 8, the purpose of tensioning the belt 5 can be achieved.

[0035] Furthermore, a base frame 13 is provided at the bottom of the frame 1. The base frame 13 is welded from multiple square tubes, and the drive device is mounted on the base frame 13.

[0036] Furthermore, five mounting plates 14 are provided on the base frame 13, and the motor 2, the tension wheel adjustment mechanism, and the second synchronous wheel 4 are respectively mounted on the mounting plates 14.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
