[0021] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the scope of protection of the present invention.

[0022] It should be understood that, in this document, the expressions "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor should they be understood as implicitly indicating the number of technical features indicated. Features defined as "first" or "second" may explicitly or implicitly indicate that at least one of the features is included.

[0023] like Figure 1-Figure 6 A tidal robot positioning mechanism shown includes a liftable walking mechanism 20 arranged at the bottom of the robot shell 10, an electromagnet assembly 50 arranged on both sides of the walking mechanism, and a metal bar 40 pre-buried in a preset position on the ground and adsorbed by the electromagnet assembly; when the walking mechanism moves to the preset position, the walking mechanism rises so that the bottom surface of the robot shell contacts the ground, and then the electromagnet assembly is energized to adsorb the metal bar. In some embodiments, the metal bar is a corrosion-resistant iron bar or iron alloy.

[0024] The electromagnet assembly 30 includes a bracket 500 and two groups of electromagnets 501 respectively arranged at both ends of the bracket. The bracket 500 is provided with a number of vertically distributed sliding rods 502, which pass through the electromagnets to form a sliding connection. A sliding hole 100 is provided at the bottom of the robot shell 10, and the lower end of the electromagnet extends into the sliding hole. A compression spring 503 is provided between the upper end of the electromagnet and the electromagnet bracket; when the bottom surface of the robot shell is separated from the ground, under the action of the compression spring, the lower end of the electromagnet exceeds a preset distance from the bottom surface of the robot shell.

[0025] A base plate 101 is fixedly arranged in the robot housing 10, a channel 102 is arranged at the bottom of the robot housing 10, a lifting mechanism 30 is arranged on the base plate 101, and the lifting mechanism includes a lower connecting plate 300 arranged under the base plate, an upper connecting plate 301 arranged on the upper side of the base plate, and a screw rod 302 fixedly arranged between the upper connecting plate and the lower connecting rod. The walking mechanism 20 is installed on the lower connecting plate 301 and rises and falls in the channel as the lower connecting plate rises and falls; a plurality of guide rods 303 sliding through the base plate are arranged between the upper connecting plate and the lower connecting plate, a screw rod seat 304 is arranged on the base plate, the screw rod passes through the screw rod seat to form a threaded connection, the screw rod seat 304 is rotatably connected to the base plate through a bearing seat 305, a driven gear 306 is fixedly arranged on the outer side of the screw rod seat, a first power 31 driving the screw rod seat to rotate is arranged on the base plate, and a driving gear 307 meshing with the driven gear is arranged on the first power. The first power is configured as a motor.

[0026] An electric-controlled indexer 32 is provided on the lower connecting plate, and the walking mechanism 20 is configured as a crawler-type walking mechanism, which is rotatably connected to the lower connecting plate and adjusts the walking angle through the electric-controlled indexer.

[0027] When in use, the walking angle of the walking mechanism is adjusted through the electric control indexer. When the walking mechanism drives the tidal robot to move to the preset position, the first power drives the lower connecting plate and the walking mechanism to rise, and the bottom surface of the robot shell drops to the ground. Then the electromagnet is energized to magnetically adsorb and locate with the metal strip pre-buried in the ground. At this time, the tidal robot is completely positioned, and the positioning flight is very stable, with strong anti-push and anti-collision performance. When it is necessary to move the position again, the electromagnet is powered off, the lifting mechanism drops and drives the tidal robot to move to another position.
