When the fixed plate 42 descends, the adjustment plate 61 squeezes the airbag 615 downward to deflate, and when the fixed plate 42 rises, the airbag 615 expands to inhale air. When the airbag 615 inhales air, the dust generated after the concrete block is compressed and broken is adsorbed through the suction nozzle 616. When the adjustment plate 61 squeezes the airbag 615, the airbag 615 discharges the dust adsorbed inside.

[0025] Reference Figure 1-Figure 6The adjusting portion includes a collar 64 fixedly connected to the adjusting plate 61, a ring gear 69 is rotatably installed in the collar 64, a rotating gear 610 is meshedly installed on the ring gear 69, when the ring gear 69 rotates, the rotating gear 610 is driven to rotate synchronously, and adjusting tooth plates 612 are meshedly installed on both sides of the rotating gear 610, and the adjusting tooth plates 612 on both sides are arranged one high and one low, the adjusting tooth plates 612 arranged one high and one low cooperate with the fixed plate 42, and the two adjusting tooth plates 612 are arranged on both sides of the rotating gear 610, when the rotating gear 610 rotates, the two adjusting tooth plates 612 slide in opposite directions, and the adjusting The section plate 61 is fixedly connected with a limit ring 614, which is slidably installed in the protective sleeve 6 to limit the moving range of the adjustment plate 61. The ring gear 69 is fixedly connected with a slip ring 613, which is slidably installed in a slideway provided on the sleeve ring 64 to ensure that the ring gear 69 remains stable during rotation. The rotating gear 610 is rotatably installed with a limit rod 611, which is fixedly installed in the sleeve ring 64. The adjusting tooth plate 612 is slidably installed in the sleeve ring 64. A chassis 2 is arranged next to the bottom plate 1, and a control console 3 is fixedly connected to the chassis 2. An oil injection pipe 51 is fixedly connected to the press 5. The oil filling pipe 51 is fixedly connected to the oil tank in the chassis 2, wherein the oil filling pipe 51 is fixedly connected to a connecting pipe 52, the connecting pipe 52 is fixedly connected to a telescopic rod 66, the collar 64 is fixedly connected to a mounting plate 65, the telescopic rod 66 is fixedly connected to the mounting plate 65, a push rod 67 is slidably installed in the telescopic rod 66, a movable tooth plate 68 is fixedly connected to the push rod 67, and the movable tooth plate 68 is meshed and installed with a ring gear 69. The movable tooth plate 68 is driven to move by the telescopic movement of the telescopic rod 66, and then the ring gear 69 is driven to rotate. When the oil filling pipe 51 starts to fill with oil and exert pressure on the concrete, the connecting pipe 52 is used to push the movable tooth plate 68 into the oil filling pipe 51. A small amount of oil is brought into the telescopic rod 66, and the oil pressure pushes the push rod 67 to drive the movable tooth plate 68 to move, and the movable tooth plate 68 drives the ring gear 69 to rotate. The adjustment tooth plate 612 below the initial state extends to the inside of the protective sleeve 6. When the fixed plate 42 descends, it abuts against the adjustment tooth plate 612, and the adjustment plate 61 is driven to descend and squeeze the airbag 615 through the adjustment tooth plate 612. When the fixed plate 42 abuts against the concrete block, it stops moving. At this time, the oil injection pipe 51 begins to inject oil into the press 5, and through the further increase of oil pressure, the press 5 begins to apply uniform and stable pressure to the concrete block. At the same time, due to the connection between the oil injection pipe 51 and the connecting pipe 52, the oil continues to flow into the telescopic rod 66, pushing the push rod 67 to continue to move forward.During this process, the movable tooth plate 68 is tightly meshed with the ring gear 69 as the push rod 67 moves, further driving the ring gear 69 to rotate. As the ring gear 69 rotates, the rotating gear 610 begins to rotate synchronously under the meshing action of the adjusting tooth plates 612 on both sides, and drives the adjusting tooth plates 612 on both sides to slide in opposite directions. At this time, the adjusting tooth plate 612 arranged above moves inward and abuts against the top of the fixed plate 42 to ensure a close fit with the fixed plate 42. After the test is completed, the fixed plate 42 rises and pulls the adjusting plate 61 up through the upper adjusting tooth plate 612, so that the airbag 615 begins to take in air.

[0026] Reference Figure 1-Figure 11 A connecting rod 11 is fixedly connected to the bottom plate 1, a top plate 12 is fixedly connected to the connecting rod 11, a slide plate 13 is slidably installed on the connecting rod 11, a driving motor 4 is fixedly connected to the slide plate 13, a threaded rod 41 is fixedly connected to the driving motor 4 through an output shaft, the threaded rod 41 is meshed and installed in the top plate 12, a fixed plate 42 is fixedly connected to the threaded rod 41, a plurality of water outlets 44 are provided in a ring array on the fixed plate 42, a valve 46 is slidably installed in the water outlet 44, the valve 46 is sealed and installed with the water outlet 44, a pull plate 47 is fixedly connected to the valve 46, a matching rod 45 is fixedly connected to the pull plate 47, the matching rod 45 is slidably installed on the fixed plate 42, and the matching rod 45 matches with the adjusting tooth plate 612, when the fixed plate 42 descends, the matching rod 45 moves to above the adjusting tooth plate 612, and the tooth plate 612 adjusts the matching rod 45 through the continuous descent of the matching rod 45. It acts as an upward force to push the matching rod 45 up. After the matching rod 45 rises, it drives the valve 46 to open. A connecting chamber 410 is opened on the fixed plate 42. The connecting chamber 410 connects several valves 46 to each other. After the valve 46 is opened, the water inside the connecting chamber 410 flows into the protective sleeve 6 through the water outlet 44, so that the concrete block is soaked with water and immersed in water, simulating the use scenario in water conservancy projects. The connecting chamber 410 is fixedly connected to the limit plate 48, and the pull plate 47 is slidably installed in the limit plate 48. The pull plate 47 is fixedly connected to the support spring 49, and the free end of the support spring 49 is fixedly connected to the connecting chamber 410. When the fixed plate 42 rises, the matching rod 45 is separated from the adjusting tooth plate 612. At this time, the valve 46 is closed again by the elasticity of the support spring 49. The connecting chamber 410 is fixedly connected to the water inlet pipe 43, and the water inlet pipe 43 is connected to the drain pipe in the chassis 2.

[0027] Reference Figure 4-Figure 8The suction nozzle 616 is fixedly connected with an air suction pipe 617, which is fixedly connected to the air inlet of the airbag 615. When the airbag 615 is stretched and inflated, suction can be generated through the air suction pipe 617 and the suction nozzle 616. The air outlet of the airbag 615 is fixedly connected with an exhaust pipe 62. A dust box 63 is fixedly installed in the chassis 2. The exhaust pipe 62 is fixedly connected to the dust box 63. When the airbag 615 is inflated, dust or impurities can be blown into the dust box 63 by squeezing the exhaust. The suction nozzle 616 is fixedly connected with a rotating shaft. 618, a rotating plate 619 is rotatably installed on the rotating shaft 618, a movable rod 620 is rotatably installed on the rotating plate 619, a floating rod 621 is fixedly connected to the movable rod 620, a slider 622 is fixedly connected to the floating rod 621, a slide groove 623 is opened on the protective sleeve 6, and the slider 622 is slidably installed in the slide groove 623. When the water level in the protective sleeve 6 rises, the water generates an upward buoyancy on the floating rod 621, and the buoyancy is transmitted to the rotating plate 619 through the movable rod 620, so that the rotating plate 619 rotates around the rotating shaft 618. The rotation of the rotating plate 619 will further drive the adsorption nozzle 616 to change its direction, causing the adsorption nozzle 616 to rotate upward to adsorb dust in the air above the water surface, thereby more effectively utilizing the suction force generated when the airbag 615 is inflated to adsorb and remove impurities or dust on the water surface. In addition, as the rotating plate 619 rotates, the angle between the movable rod 620 and the floating rod 621 will also change. This change is stably supported by the sliding of the slider 622 in the slide groove 623, ensuring that the entire mechanism remains stable during rotation. When the water level in the protective cover 6 drops, the buoyancy of the floating rod 621 decreases, and the rotating plate 619 and the adsorption nozzle 616 will gradually return to their initial positions under the action of gravity, waiting for the next rise in water level. A return spring 624 is fixedly connected to the rotating plate 619 , and the free end of the return spring 624 is fixedly connected to the floating rod 621 . A sliding ball 625 is fixedly connected to the movable rod 620 . A corrugated tooth plate 626 is fixedly connected to the protective sleeve 6 , and the corrugated tooth plate 626 cooperates with the sliding ball 625 .

[0028] Reference Figure 1 , Fig.12The press machine 5 is fixedly connected with a backing plate 7, and a cavity is arranged inside the backing plate 7. The cavity receives water flowing from the water leakage port of the floating plate 72. A hydraulic plate 73 is slidably installed in the backing plate 7. A sleeve 53 is fixedly connected to the press machine 5. The hydraulic plate 73 is plugged and installed with the sleeve 53. The sleeve 53 is pressed by the press machine 5 to drive the hydraulic plate 73 to rise. The plug-in installation of the hydraulic plate 73 is convenient for disassembly. A floating plate 72 is fixedly installed on the hydraulic plate 73. A water leakage port is opened on the floating plate 72. When water flows When entering the protective cover 6, it enters the cavity along the water leakage hole on the floating plate 72 and generates buoyancy on the floating plate 72. When the detection is completed, the floating plate 72 drives the hydraulic plate 73 and the broken concrete blocks above it to rise through buoyancy, and the broken concrete blocks are also lifted up. In this process, the floating plate 72 not only bears the weight of the concrete blocks, but also uses the buoyancy generated by the water flow to raise the pad 7, which is fixedly connected to the drain pipe 71 for draining the water in the cavity. The protective cover 6 is fixedly connected to the pad 7.

[0029] In the present invention, when testing the quality of concrete for water conservancy projects, the concrete block to be tested is first placed inside the protective sleeve 6, and then the drive motor 4 is started to drive the threaded rod 41 to rotate through its output shaft. The rotation of the threaded rod 41 causes the fixed plate 42 to descend along the connecting rod 11 and enter the protective sleeve 6. During the descent of the fixed plate 42, the matching rod 45 gradually approaches the adjusting tooth plate 612. Once the matching rod 45 is contacted and pushed by the adjusting tooth plate 612, the valve 46 opens, and the water in the connecting cavity 410 flows into the protective sleeve 6 through the water outlet 44 until the concrete block is completely immersed. This step simulates the actual use scenario of concrete in water conservancy projects, which helps to more accurately evaluate its quality.

[0030] When the water level in the protective sleeve 6 rises, the floating rod 621 is affected by the buoyancy of the water, and drives the rotating plate 619 to rotate around the rotating shaft 618 through the movable rod 620. The rotation of the rotating plate 619 further changes the direction of the adsorption nozzle 616, so that it can more effectively adsorb dust and impurities in the air above the water surface. With the fluctuation of the water level, the rotating plate 619 and the adsorption nozzle 616 can automatically adjust the angle to meet different detection needs. After the concrete block is fully soaked, the press 5 is operated to supply oil through the console 3. The press 5 applies pressure to the hydraulic plate 73 through the sleeve 53 to push it up. The rise of the hydraulic plate 73 drives the floating plate 72 and the concrete block thereon to rise together, and cooperates with the fixed plate 42 to apply pressure to the concrete block. When the press 5 is supplied with oil, it also drives the movable tooth plate 68 to move, and the movable tooth plate 68 drives the ring gear 69 to rotate, so that the two adjusting tooth plates 612 exchange positions, and the upper adjusting tooth plate 612 abuts against the upper part of the fixed plate 42. The adjusting tooth plate 612 is retracted, so that the water outlet 44 is closed and stops discharging water. The quality of the hydraulic plate 73 can be evaluated by the rising force of the hydraulic plate 73 displayed on the console 3. After the inspection is completed, the oil filling pipe 51 is closed, and the driving motor 4 controls the threaded rod 41 to rotate and drive the fixed plate 42 to rise. After the fixed plate 42 rises, the adjusting plate 61 is driven to rise synchronously, so that the airbag 615 starts to inflate. The inflation process of the airbag 615 generates a strong suction force through the suction pipe 617 and the adsorption nozzle 616, which not only helps to remove dust and impurities on the surface of the concrete, but also discharges the inhaled dust into the dust box 63 through the exhaust pipe 62, so as to achieve the cleaning of the inspection environment. After the inflation of the airbag 615 is completed, the oil is released through the oil filling pipe 51 to return the movable tooth plate 68 to its position, and the buoyancy generated by the floating plate 72 and the water drives the hydraulic plate 73 and the concrete fragments above it to rise synchronously, so as to facilitate the cleaning of the waste. After the cleaning is completed, the drain pipe 71 is opened to discharge the water source inside the protective sleeve 6, so as to facilitate the subsequent inspection and maintenance work.
