In addition, a limiting groove 701 is provided on the connecting plate 7, and the connecting rod 13 is passed downward from the limiting groove 701, so as to further strengthen the limiting and stress resistance of the connecting rod 13, and prevent the connecting rod 13 from being subjected to the action of wind and waves to generate a large stress in order to resist the swing.

[0026] An annular shielding plate 4 is fixedly connected to the pile foundation 1 above the toothed disc 3, the first motor 6 is fixedly connected to the upper side of the shielding plate 4 corresponding to the gear 5, and the output shaft of the first motor 6 passes through the shielding plate 4 and is fixedly connected to the gear 5. An annular convex edge 404 located on the outer side of the toothed disc 3 is provided at the bottom edge of the shielding plate 4 in a circumferential downward direction to limit the toothed disc 3 and prevent the toothed disc 3 from being separated from the gear 5, and also prevent the toothed disc 3 from being separated from the connecting disc 2.

[0032] In this embodiment, in order to ensure the balance of the toothed disc 3, there are two connecting plates 7, which are symmetrically arranged on the outside of the toothed disc 3. Each connecting plate 7 is provided with a connecting rod 13 that can move along the length direction of the connecting plate 7. A sonar 15 is installed at the bottom of each connecting rod 13, so that the two sonars 15 can work simultaneously, thereby improving the monitoring efficiency and the accuracy of the monitoring results.

[0033] The working process of this embodiment is as follows:

[0034] The gear 5 is driven to rotate by the first motor 6, driving the toothed disc 3 to rotate along the axis. During the rotation of the toothed disc 3, the ring groove on the connecting disc 2, the ball bearing and the limiting groove on the toothed disc 3 are cooperated, and the cooperation of the baffle plate 4 and the convex edge 404 is combined to limit the toothed disc 3 so that it can achieve stability in rotation along the axis; the screw 10 is driven to rotate by the second motor 9, driving the connecting block 12 to move on the screw 10, realizing radial movement of the connecting rod 13, and then realizing the change of the distance between the sonar 15 and the pile foundation 1, so that the monitoring range of the sonar 15 is wider.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
