[0034] Reference Figure 1 , Figure 2 and Figure 5In a preferred embodiment, two mounting brackets 14 are fixedly connected to the bottom inner wall of the mounting frame 1, the inner walls of the two mounting brackets 14 are fixedly connected with electric push rods 13, the output ends of the two electric push rods 13 are fixedly connected with fixing parts 15, the outer walls on the opposite sides of the two fixing parts 15 are fixedly connected with the same collecting frame seat 2, three collecting boxes 12 are arranged on the collecting frame seat 2, and the collecting frame seat 2 and the outer wall on one side of the detection frame 6 are fixedly connected with the same fixed plate rack 8; the sample receiving buffer module 7 includes two mounting blocks 701, the two mounting blocks 701 are fixedly connected to the top inner wall of the mounting frame 1, the outer walls on one side of the two mounting blocks 701 are fixedly connected with telescopic spring rods 706, one end of the two telescopic spring rods 706 are fixedly connected with a connecting frame 705, and the outer walls on the opposite sides of the two connecting frames 705 are fixedly connected with the same A buffer frame 704 is provided, and the inner walls on both sides of the buffer frame 704 are connected to the same mounting rod 707 through bearings, the outer wall of the mounting rod 707 is fixedly connected to the buffer plate 703, and the top of the buffer plate 703 is fixedly connected to the elastic corrugated plate 702; the inner walls on both sides of the buffer frame 704 are connected to the mounting shaft rod 708 through bearings, the outer walls of the two mounting shaft rods 708 are fixedly connected to the resistance sleeve 711, and the two resistance sleeves 711 are provided with resistance plate members 710, and the inner walls of one side of the two resistance sleeves 711 are fixedly connected to the tension spring 709, one end of the two tension springs 709 is respectively fixedly connected to the outer wall of one side of the two resistance plate members 710, and the buffer plate 703 is connected to two connecting rod members 712 through bearings, and one end of the two connecting rod members 712 is respectively fixedly connected to the outer wall of the other side of the two resistance plate members 710.
[0035] Specifically, after the detection, the electric push rod 13 is started, and the electric push rod 13 drives the fixing member 15 to move, and then drives the collecting frame seat 2 to move through the fixing member 15. At this time, the fixed plate frame 8 can drive the detection frame 6 to move synchronously. With the movement of the detection frame 6, the concrete test block will move accordingly and gradually separate from the top of the installation frame 1, so that the concrete test block falls. At this time, with the movement of the fixed plate frame 8, the telescopic spring rod 706 drives the buffer frame 704 to move, so that the concrete test block contacts the buffer plate 703 and the elastic corrugated plate 702 when it falls. At this time, the impact force of the fall will drive the buffer plate 703 to rotate, and then the connecting rod 712 pulls the resistance plate 710. Since there is a certain resistance between the resistance plate 710 and the outer wall of the resistance sleeve frame 711, the tensile spring 709 can be used to buffer the impact force of the concrete test block falling until the concrete test block falls into the collecting box 12. At this time, the buffer plate 703 is reset, and the recovery of multiple concrete test blocks is completed;

[0037] Reference Figure 1 , Figure 5 and Figure 8 In a preferred embodiment, the cleaning module 3 includes a negative pressure filter chamber 302, which is fixedly connected to an outer wall of one side of the detection frame 6, and a negative pressure pump 301 is fixedly connected to an outer wall of one side of the negative pressure filter chamber 302, and a connecting pipe 305 is fixedly connected to an outer wall of the other side of the negative pressure filter chamber 302, and an input end of the connecting pipe 305 is fixedly connected to a cleaning chamber 307; a plurality of cleaning ports 306 are equidistantly provided on the outer wall of the cleaning chamber 307, and a processing port 303 is provided on the outer wall of the negative pressure filter chamber 302, and a closed ring plate 304 is rotatably connected to the outer wall of the negative pressure filter chamber 302.
[0038] Specifically, during operation, since there is a certain gap between the detection frame 6 and the installation frame 1, as the detection frame 6 moves, the concrete test block is recovered. At this time, the fine concrete fragments or dust generated during the detection of the concrete test block will remain on the top of the installation frame 1 due to this gap. At this time, as the detection frame 6 moves, the negative pressure pump 301 is started, and the gas inside the negative pressure filter bin 302 is discharged through the negative pressure pump 301. At this time, the inside of the negative pressure filter bin 302 is in a negative pressure state, and then the connection through the connecting pipe 305 can make the inside of the cleaning bin 307 suck in the gas, and at the same time, the small fragments enter the cleaning bin 307 through the cleaning port 306, until the fine concrete fragments or dust remaining on the top of the installation frame 1 are completely cleaned with the movement of the detection frame 6, and then the small fragments are transported to the inside of the negative pressure filter bin 302 to complete the cleaning and storage. After cleaning, the closed ring plate 304 is rotated to open the processing port 303 to carry out centralized processing of the fragments;
[0039] In a specific application scenario, the cleaning module 3 is suitable for the cleaning of concrete test block fragments, that is, the cleaning module 3 can clean the remaining small fragments on the top of the installation frame 1 after the concrete test block is recovered, so as to avoid the residual small fragments causing the subsequent concrete test block to be tilted, thereby ensuring the detection effect. At the same time, the cleaning module 3 can ensure the cleanliness of the top of the installation frame 1 after cleaning the small fragments, and avoid the detection frame 6 from contacting with small fragments when resetting, causing wear on the top surface of the installation frame 1, so as to increase the use effect and diversity of the device.
[0040] A civil engineering concrete strength testing method, using the civil engineering concrete strength testing device as described above, comprises the following steps:
[0041] Step 1: Set the concrete test block inside the detection frame 6. During the detection, start the electric telescopic rod 502, which can drive the fixed sleeve frame 504 and the drive motor 508 to rise and fall, and then the drive motor 508 drives the mounting frame 520 to rise and fall until the drive gear 506 on the mounting frame 520 is meshed with the inner tooth plate 507. At this time, start the drive motor 508, and the drive motor 508 drives the mounting frame 520 to rotate, thereby driving the drive gear 506 to move. Since the drive gear 506 is meshed with the inner tooth plate 507, the drive gear 506 is meshed with the inner tooth plate 507. The wheel 506 drives the shaft member 511 to rotate, thereby driving the winding wheel 505 to tighten or loosen the connecting cable 518. At this time, the position of the movable block 516 can be adjusted by cooperating with the pressure spring 513, thereby adjusting the position of the installation frame 515 and the hydraulic rod. After the adjustment, the hydraulic rod is started, and the pressure plate 517 can be driven by the hydraulic rod to perform strength testing on the concrete test block. After the test, the position of the hydraulic pump 512 is adjusted again to perform multi-area testing. At the same time, during the test, the position of the inner tooth plate 507 can be adjusted by the electric rod 501 to perform testing on different test blocks.
[0042] Step 2, after the detection, the electric push rod 13 is started, and the electric push rod 13 drives the fixing part 15 to move, and then drives the collecting frame seat 2 to move through the fixing part 15. At this time, the fixed plate frame 8 can drive the detection frame 6 to move synchronously. With the movement of the detection frame 6, the concrete test block will move accordingly and gradually separate from the top of the installation frame 1, so that the concrete test block falls. At this time, with the movement of the fixed plate frame 8, the telescopic spring rod 706 drives the buffer frame 704 to move, so that the concrete test block contacts the buffer plate 703 and the elastic corrugated plate 702 when it falls. At this time, the impact force of the fall will drive the buffer plate 703 to rotate, and then the connecting rod 712 pulls the resistance plate 710. Since there is a certain resistance between the resistance plate 710 and the outer wall of the resistance sleeve frame 711, the tensile spring 709 can buffer the impact force of the concrete test block falling until the concrete test block falls into the collecting box 12. At this time, the buffer plate 703 is reset, and the recovery of multiple concrete test blocks is completed;
[0043] Step three, during operation, since there is a certain gap between the detection frame 6 and the installation frame 1, as the detection frame 6 moves, the concrete test block is recovered. At this time, the fine concrete fragments or dust generated during the detection of the concrete test block will remain on the top of the installation frame 1 due to this gap. At this time, as the detection frame 6 moves, the negative pressure pump 301 is started, and the gas inside the negative pressure filter bin 302 is discharged through the negative pressure pump 301. At this time, the inside of the negative pressure filter bin 302 is in a negative pressure state, and then the connection through the connecting pipe 305 can allow the inside of the cleaning bin 307 to inhale gas, and at the same time allow small fragments to enter the cleaning bin 307 through the cleaning port 306, until the fine concrete fragments or dust remaining on the top of the installation frame 1 are completely cleaned as the detection frame 6 moves, and then the small fragments are transported to the inside of the negative pressure filter bin 302 to complete cleaning and storage. After cleaning, the closed ring plate 304 is rotated to open the processing port 303 for centralized processing of the fragments.
