[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: an underwater cast-in-place pile top slurry measuring device, comprising a mounting frame 1 and a buoy 8, a reel 2 is rotatably fitted inside the mounting frame 1, a traction rope 7 is installed between the reel 2 and the buoy 8, a mud cleaning structure is installed at the bottom of the mounting frame 1, the mud cleaning structure corresponds to the traction rope 7, floating plates 9 are fixed on the upper and lower sides of the buoy 8, a piston 12 is slidably fitted inside the buoy 8, and a plurality of slurry inlets 11 are opened on the peripheral side of the bottom of the buoy 8.

[0023] In this embodiment, a first motor 3 is fixed to one side of the mounting frame 1, an output end of the first motor 3 is fixedly connected to the drum 2, one end of a traction rope 7 is wound around the drum 2, and the other end of the traction rope 7 is fixedly connected to the float 8. The mud cleaning structure includes a scraper 6 fixed to the bottom of the mounting frame 1. The scraper 6 is a ring-shaped structure, and the scraper 6 corresponds to the traction rope 7. A through groove 4 is provided at the bottom of the mounting frame 1, and the through groove 4 corresponds to the traction rope 7. The scraper 6 is located on the side of the through groove 4, and a resistance wire 5 is fixed in the through groove 4.

[0024] Specifically, when the buoy 8 sinks, the first motor 3 is started, so that the first motor 3 drives the reel 2 to rotate, so that the reel 2 loosens the traction rope 7, and the buoy 8 can sink into the mud under the action of gravity. When winding, the first motor 3 rotates in the opposite direction, so that the first motor 3 drives the reel 2 to wind up the traction rope 7, and the buoy 8 can be pulled out. When the traction rope 7 is pulled out and wound, the traction rope 7 will pass through the scraper 6 and the through groove 4, and the scraper 6 can scrape off a large amount of mud adhered to the traction rope 7. At the same time, the resistance wire 5 is energized to make the resistance wire 5 heat up, and the traction rope 7 can be dried, thereby reducing the weight of the traction rope 7 and extending the service life of the traction rope 7.

[0025] A second motor 10 is fixed in the buoy 8, and a threaded rod 15 is fixed to the output end of the second motor 10. The threaded rod 15 is threadedly matched with the piston 12. A slide groove 14 is opened in the buoy 8, and the slide groove 14 corresponds to the piston 12. A sealing gasket is installed on the surrounding side of the piston 12. A battery and a wireless module can be installed in the buoy 8. The second motor 10 is started by the wireless module, and the second motor 10 is powered by the battery.

[0026] Specifically, when the mud density is too high and the buoy 8 cannot sink, the second motor 10 is started so that the second motor 10 drives the threaded rod 15 to rotate, thereby driving the piston 12 to move up and down, so that negative pressure is generated in the buoy 8, thereby absorbing the mud into the buoy 8 and increasing the weight of the buoy 8, so that the buoy 8 can sink until the floating plate 9 contacts the concrete pile. The floating plate 9 can prevent the buoy 8 from causing damage to the concrete pile.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
