[0037] like Figures 1 to 6 As shown, a deepwater operation platform for a reservoir dam includes a platform frame 1, on which an underwater hydraulic system 2 and a plurality of thrusters 3 are arranged, and on which a plurality of floating blocks 4 are arranged. The overall size of the platform frame 1 currently designed is 4800 mm long, 2000 mm wide, and 1300 mm high. A limiting chassis 5 is arranged on one side of the platform frame 1, and the working tool is placed on the limiting chassis 5. When in use, a plurality of limiting plates 16 are arranged on the limiting chassis 5 to form a groove shape to limit the periphery of the working tool to prevent it from moving left and right and up and down. The main frame structure of the platform frame 1 is welded by steel pipes. The frame baskets on the left and right sides of the frame body are used to place the underwater packaged hydraulic system 2, and the extension frames on the front and rear sides are used to place the underwater high-power thrusters to realize the underwater movement control of the four thrusters. A hollow working port 101 is arranged on the side of the platform frame 1 close to the reservoir dam, which is used for the working tool to move in this area. In this embodiment, the hollow working port 101 is 2200 mm long and 1800 mm wide.

[0038] A transverse guide rail 6 and a vertical guide rail 7 are provided on the platform frame 1. Transverse sliders 8 cooperating with the transverse guide rail 6 are provided at both ends of the vertical guide rail 7, so that the vertical guide rail 7 can move along the transverse guide rail 6. A vertical slider 9 is provided on the vertical guide rail 7. A mounting frame 10 is provided on the vertical slider 9. A robotic arm 11 is provided on the mounting frame 10. The robotic arm 11 can move along the vertical guide rail 7. Since the vertical guide rail 7 can move along the transverse guide rail 6, the robotic arm 11 can move in two dimensions, so that the robotic arm 11 can move in the area covered by the hollow working opening 101. The transverse slider 8 and the vertical slider 9 are driven by a mobile driving mechanism.

[0039] The mobile driving mechanism includes a first rack 13 arranged on the transverse guide rail 6 or the vertical guide rail 7, a first driving motor 14 is arranged on the vertical guide rail 7 or the mounting frame 10, and an output shaft of the first driving motor 14 is provided with a first gear 15 meshing with the first rack 13.

A plurality of conical microneedles 1205 are provided near the bottom of the reservoir dam of the suction cup shell 1201.

[0042] The basic principle of the swirl suction cup is to use an underwater motor to drive the suction cup blades to stir the water flow inside the suction cup shell, thereby accelerating the water flow inside the suction cup shell to rotate at a high speed around the central axis of the suction cup blades. According to the Bernoulli principle, the water flow velocity inside the suction cup shell is large, while the water flow velocity outside the suction cup shell is small. The part with a large flow velocity has a large pressure, forming a pressure difference on both sides of the suction cup, thereby generating suction.

[0043] By setting the conical microneedle 1205 and inserting it into the surface of the dam concrete, the conical microneedle 1205 collides with the wall surface to produce a conical pit, and the microneedle remains in the wall surface to form a lateral limit, thereby increasing the friction.
