The side wall of the third sliding groove 4 presses against the pressing plate 1102. The second spring 1103 and the elastic connecting piece 1101 are compressed. The pressing plate 1102 drives the pressing block 1105 to insert into the clamping groove 10. The pressing block 1105 pushes the clamping block 313, causing the clamping block 313 to disengage from the clamping groove 10.

[0057] The pressing block 1105 cooperates with the clamping groove 10.

[0058] When the utility model is in use, the electrical components appearing in this application are externally connected to a power source and a control switch during use. The concrete blocks used for dam test detection are placed on the dam concrete strength detection table 1. The hydraulic cylinder 6 pushes the pressing plate 7 to descend. The pressing plate 7 drives the sliding rod 303 to descend. The clamping block 313 on the sliding rod 303 is clamped in the clamping groove 10. The descending of the sliding rod 303 pulls the moving sleeve 301 to descend synchronously;

[0059] The moving sleeve 301 drives the third rotating tooth groove 5 to descend. The third rotating tooth groove 5 drives the rotating gear 327 to rotate. The rotating gear 327 rotates in the second rotating tooth groove 325 and drives the connecting rod 323 to rise. The connecting rod 323 drives the first rotating tooth groove 324 to rise.

[0060] At this time, the baffle 302 abuts against the top of the dam concrete strength detection table 1. The pressing plate 1102 is located in the third sliding groove 4.

The pressing plate 1102 drives the pressing block 1105 to insert into the clamping groove 10. The pressing block 1105 pushes the clamping block 313, so that the clamping block 313 disengages from the clamping groove 10. When the pressing plate 7 continues to descend, the sliding rod 303 is no longer restricted and moves downward with the pressing plate 7. The pressing plate 7 squeezes the concrete block. The pressure sensor 8 detects the pressing force, and observes the situation of the concrete being pressed through the observation plate;

[0061] After the detection is completed, the hydraulic cylinder 6 drives the pressing plate 7 to rise. The pressing plate 7 first drives the sliding rod 303 to slide upward in the moving sleeve 301 until the sliding rod 303 abuts against the baffle 302. At this time, the clamping block 313 is facing the clamping groove 10. The pressing plate 7 continues to rise, driving the sliding rod 303 to push the baffle 302 to rise. The baffle 302 drives the moving sleeve 301 to rise. The rising of the moving sleeve 301 synchronously drives the connecting rod 323 to descend. The descending of the connecting rod 323 drives the shielding plate 201 to rotate upward and open. When the pressing plate 1102 disengages from the third sliding groove 4, the second spring 1103 and the elastic connecting piece 1101 expand and push the pressing block 1105 to disengage from the clamping groove 10. The first spring 312 expands and pushes the clamping block 313 to be re-clamped into the clamping groove 10 to limit the sliding rod 303, facilitating the shielding plate 201 to synchronously shield and open the dam concrete strength detection table 1 as the pressing plate 7 descends and rises, making the whole operation process convenient.
