[0027] Furthermore, a second support plate 318 is fixedly connected to the outer wall of the base plate 1, and the end of the first electric telescopic rod 315 away from the block 316 is rotatably connected to the inner outer wall of the second support plate 318, so that when the connecting card plate 317 rotates, the threaded rod 319 can be driven to rotate, and the first electric telescopic rod 315 can be supported and rotated by the second support plate 318.

[0028] Furthermore, the slot on the outer wall of the connecting clamp 317 is in the shape of a "cross", and the outer wall of the clamp block 316 fits snugly with the inner wall of the slot, so that the connecting clamp 317 can be limitedly connected to the clamp block 316, thereby driving the threaded rod 319 to rotate.

[0029] The limit test mechanism 32 includes a second electric telescopic rod 321 fixedly connected to the bottom end of the inner side of the support frame 2, the output end of the second electric telescopic rod 321 is fixedly connected to a cover plate 322, the bottom end of the cover plate 322 is fixedly connected to a connecting rod 323, the end of the connecting rod 323 away from the cover plate 322 is fixedly connected to a force block 324, the top of the bottom plate 1 is fixedly connected to a fixed block 325, the outer wall of the fixed block 325 is provided with a sliding hole, the inner wall of the sliding hole is slidably connected to a plug rod 326, one end of the plug rod 326 is fixedly connected to a force block 328, the force block 328 is fixedly connected to a spring 327 near the end of the plug rod 326, and the end of the spring 327 away from the force block 328 is fixedly connected to the outer wall of the fixed block 325.

[0030] Furthermore, a sealing groove is provided at the bottom of the cover plate 322, and the inner wall of the sealing groove fits snugly with the top opening of the test mold 3113, so that the cover plate 322 can perform a good sealing effect on the top opening of the test mold 3113, thereby better performing subsequent testing work.

[0031] Furthermore, there are two force blocks 324 and two force blocks 328, which are distributed on the left and right sides of the test mold 3113 in a left-right symmetrical structure. In this way, the insertion rods 326 on the left and right sides of the test mold 3113 can be squeezed and moved, thereby synchronously limiting the left and right sides of the test mold 3113, thereby improving the stability of the test mold 3113 during the test process.

[0032] The implementation principle of a concrete anti-seepage performance testing device of the present embodiment is as follows: after completing a test, the limiting effect on the test mold 3113 can be released, and then the test mold 3113 is rotated ninety degrees clockwise by rotating the rotating shaft 3112, and then the first electric telescopic rod 315 is started to drive the block 316 to be inserted into the connecting card plate 317, and then the double-axis motor 312 is started, and its output end will drive the transmission wheel 313 to rotate, and when the transmission wheel 313 rotates, it drives the transmission belt 314 to rotate, so that the transmission belt 314 will drive the first electric telescopic rod 315 to rotate, and when the first electric telescopic rod 315 rotates, it can drive the connecting card plate 317 to rotate. When the connecting clamping plate 317 rotates, the threaded rod 319 will be driven to rotate, thereby driving the threaded block 3110 to move to the right. When the threaded block 3110 moves, the test mold 3113 at the top can be driven to move, so that the test mold 3113 can be moved to the position of the cleaning roller 3114 until the cleaning roller 3114 is completely immersed in the test mold 3113, and then the first electric telescopic rod 315 is started to retract, and the engagement connection between the clamping block 316 and the connecting clamping plate 317 is released. At this time, the dual-axis motor 312 continues to rotate, driving the cleaning roller 3114 to rotate, and the concrete remaining on the inner wall of the test mold 3113 is washed, so that the test mold 3113 does not need to be repeatedly disassembled and assembled.

[0033] After the test mold 3113 is moved to the right below the cover plate 322, the second electric telescopic rod 321 is started to drive the cover plate 322 to move downward. When the cover plate 322 moves downward, the connecting rod 323 is driven downward, thereby driving the force block 324 to move downward until it contacts and squeezes the force block 328. The squeezed force block 328 drives the insertion rod 326 to move to the middle position of the test mold 3113, and at the same time squeezes and compresses the spring 327. At this time, the insertion rod 326 will be inserted into the bottom of the test mold 3113 The card hole opened in the outer wall of the end completes the limiting effect on the test mold 3113, and the synchronous cover plate 322 will complete the sealing effect on the top of the test mold 3113. When the limiting of the test mold 3113 is released, the output end of the second electric telescopic rod 321 is started to retract, which can drive the connecting rod 323 and the force block 324 to move upward, releasing the contact and extrusion on the force block 328, and then the spring 327 rebounds and resets, thereby driving the insertion rod 326 to reset and move, and disengage from the limiting effect on the test mold 3113.
