[0022] Furthermore, the counterweight 5 acts on the internal position of the protective frame 1 through the measuring line 3, the supporting base 2 is in a circular ring shape, the measuring line 3 passes through the surface of the protective frame 1 and is fixedly connected to the counterweight 5, through the connection between the measuring line 3 and the counterweight 5, and under the connection between the pull rope 4 and the measuring line 3, the control effect of the acting position of the counterweight 5 in the protective frame 1 is achieved.

[0023] Furthermore, the limit blocks 6 are evenly distributed on both sides of the measuring line 3, the surface of the limit blocks 6 is in an arc shape, the rotating ball 7 is in a spherical shape, and the cross-section of the placement bin 8 is in a fan-shaped shape. Through the connection between the measuring line 3 and the limit blocks 6, under the action of the limit blocks 6, the sliding direction of the measuring line 3 on the protective frame 1 is limited. Under the connection between the rotating ball 7 and the counterweight 5, through the action of the rotating ball 7, when the counterweight 5 contacts with stones or hard objects in the sediment, the descending path of the counterweight 5 is changed to avoid a large mistake in the sediment measurement.

[0024] Furthermore, the placement bins 8 are opened in two groups on the surface of the counterweight block 5, the counterweight balls 9 are placed inside the counterweight block 5 through the placement bins 8, the float reduction grooves 10 are in the shape of square grooves, and the float reduction grooves 10 are evenly distributed on the surface of the supporting base 2. Through the connection between the placement bins 8 and the counterweight block 5, under the action of the placement bins 8 and the counterweight balls 9, by changing the number of counterweight balls 9 in the placement bins 8, the weight of the counterweight block 5 can be controlled.

[0025] Furthermore, the control board 11 is in a plate shape and acts on the inner side of the floating trough 10. The control board 11 is symmetrically distributed in two groups on the inner side of the floating trough 10. A circular groove is opened on the inner side of the floating trough 10. The control board 11 is rotatably connected to the floating trough 10 through the circular groove. Through the connection between the floating trough 10 and the supporting base 2, under the action of the floating trough 10, the buoyancy of the supporting base 2 is reduced when it descends, thereby improving the stability of the equipment when it descends.

[0026] Furthermore, the control board 11 is elastically rotatably connected to the float reduction tank 10 via a torsion spring 12. The connecting groove 13 is in the shape of a groove. The connecting groove 13 acts on both sides of the interior of the protective frame 1.

[0028] Working principle: When measuring the sediment at the bottom of the pile, the protection frame 1 and the counterweight 5 are lowered by the pull rope 4. During the lowering process, the buoyancy of the water causes the control board 11 to rotate in the floating trough 10. At this time, the effective size of the floating trough 10 becomes larger, reducing the contact buoyancy between the support base 2 and the water, and maintaining the descending state of the protection frame 1. When the support base 2 contacts the sediment, the control board 11 is reset under the action of the torsion spring 12, thereby improving the stability of the support base 2 supporting the protection frame 1. After the position of the support base 2 is fixed, the pull rope 4 is lowered. Under the action of the weight of the counterweight 5, the measuring line 3 slides in the protection frame 1. When the measurement is completed, the pull rope 4 is pulled. At this time, the limit block 6 and the limiting block 15 are abutted. Under the contact between the limiting block 15 and the protection frame 1, the effective position of the counterweight 5 is fixed. The measurement result of the thickness of the sediment at the bottom of the pile is obtained by measuring the lowering distance of the measuring line 3.
