[0019] Step 1: Move, push the push rod or pull, so that the first lifting rod and the moving rod drive the moving block to move in the first slide groove, and a blocking block is arranged on the roller surface at the bottom of the base. When the roller rolls, the blocking block will hinder the rolling of the roller, so that the moving block can move in the first slide groove. When the moving block is supported at the end of the first slide groove, the blocking block is pushed into the roller after being subjected to force, and the roller can rotate to drive the base to move.

Pull up the pushing rod to make the first lifting rod move on the surface of the vertical rod. The supporting plate pushes the cross bar to realize the upward movement of the ultrasonic rebound tester. After releasing the pulling of the pulling rod, the spring in the third sliding groove pushes the holding rod so that the holding rod is held in another set of limiting grooves, fixing the positions of the first lifting rod and the supporting plate, and the supporting plate drives the connecting rod to move upward.

3. A concrete quality detection device for water conservancy engineering according to claim 2, characterized in that: The ultrasonic rebound tester (24) is lowered into the through hole (3) and then supported on the surface of the concrete, emitting ultrasonic waves to the concrete for detection.

4. A detection method for a concrete quality detection device for water conservancy engineering according to any one of claims 1 to 3, characterized in that: The following steps are involved: Step 1: Move, push the push rod (30) or pull it, so that the first lifting rod (5) and the moving rod (11) drive the moving block (12) to move in the first slide groove (14), and the surface of the roller (4) at the bottom of the base (1) is provided with a blocking block (31). When the roller (4) rolls, the blocking block (31) will hinder the rolling of the roller (4), so that the moving block (12) can move in the first slide groove (14). When the moving block (12) is held at the end of the first slide groove (14), the blocking block (31) is subjected to force and is In the jacking roller (4), the roller (4) can rotate to drive the base (1) to move, and the first lifting rod (5) drives the supporting plate (10) to move during the movement, so that the protrusion (9) is supported on the surface of the cross bar (27), and the cross bar (27) moves upward in the vertical groove (26). The cross bar (27) drives the second lifting rod (23) to move upward, so that the ultrasonic rebound tester (24) moves upward, and the ultrasonic rebound tester (24) is away from the concrete ground. The ultrasonic rebound tester (24) can be quickly moved upward and move along with the base (1); Step 2: Testing, after the base (1) stops moving, the protrusion (9) no longer presses against the bottom of the cross bar (27), the ultrasonic rebound tester (24) descends under the action of gravity, and the end of the second lifting rod (23) presses against the surface of the force ring (21) after descending, the third spring (22) plays a buffering role, and the end of the ultrasonic rebound tester (24) presses against the surface of the concrete to test the concrete; Step 3: Storage. When the ultrasonic rebound tester (24) is not in use, the pulling rod (29) is pulled to move the pulling rod (29) in the third slide groove (28). The pulling rod (29) drives the supporting rod (6) to move so that the supporting rod (6) is no longer stuck in the limiting groove (7). The pushing rod (30) is pulled upward to move the first lifting rod (5) on the surface of the vertical rod (8). The supporting plate (10) pushes the horizontal rod (27) to achieve the upward movement of the ultrasonic rebound tester (24). After releasing the pulling of the pulling rod (29), the spring in the third slide groove (28) pushes the supporting rod (6) so that the supporting rod (6) is supported in another set of limiting grooves (7). The positions of the first lifting rod (5) and the supporting plate (10) are fixed. The supporting plate (10) drives the connecting rod (15) to move upward. The connecting rod (15) drives The movable plate (20) and the clamping ring (18) move upward, and the movable plate (20) is pushed by the through hole (3), so that the movable ring (17) moves in the second slide groove (19), so that the clamping ring (18) is clamped on the surface of the ultrasonic rebound tester (24), playing a supporting role, and the end of the movable plate (20) is inserted into the insertion groove (25), and if the connecting rod (15) moves downward, the connecting rod (15) moves downward inside the movable ring (17) and does not drive the clamping ring (18) to move downward. Therefore, when the ultrasonic rebound tester (24) is not used, it is ensured that the clamping ring (18) is supported on the bottom of the ultrasonic rebound tester (24), so that the ultrasonic rebound tester (24) will not fall off, and when the blocking block (31) is worn, the screw rod (33) is screwed, and the screw rod (33) causes the blocking block (31) to extend from the roller (4).
