Specifically, the underwater carrying device provided by the embodiment of the invention is put into water, the counterweight body 02 is submerged into the water, the floating body 01 floats on the water surface, two ends of the rope 03 are respectively pulled downwards by the counterweight body 02 and pulled upwards by the floating body 01, and the rope 03 sequentially passes through the first through hole 0412, the gap between the two first sliding bodies 043 and the second through hole 0413 from top to bottom; in water, the upper floating body 042 moves upwards relative to the bracket body 041 and drives the first sliding body 043 to move upwards in the gathering groove 0411; the distance between the two side walls of the gathering groove 0411 gradually decreases from bottom to top, and the two first sliding bodies 043 are pushed inwards; the two first sliding bodies 043 move inwards under the action of the guiding structure on the upper floating body 042, the rope 03 is positioned in a gap between the two first sliding bodies 043, the two first sliding bodies 043 press the rope 03 inwards, friction force is generated between the first sliding bodies 043 and the rope 03, the friction force of the rope 03 to the first sliding bodies 043 points upwards along the rope 03, the friction force is balanced with the difference between the gravity and the buoyancy of the carrying unit 04 in water, and the carrying unit 04 is hung on the rope 03 and is static relative to the rope 03.
When the floating body 01 moves downwards under the action of water surface waves, the rope 03 moves downwards along with the rope 03, the two first sliding bodies 043 are driven by the rope 03 to move downwards relative to the gathering groove 0411, and as the distance between the two side walls of the gathering groove 0411 is gradually increased from top to bottom, the two first sliding bodies 043 move outwards relative to each other and are far away from the rope 03, and the carrying unit 04 is driven by gravity to move downwards. Since the downward movement of the carrying unit 04 occurs under the action of the difference between the gravity and the buoyancy of the carrying unit, the acceleration of the movement is small; the rope 03 moves downwards along with the wave, so that the acceleration of the movement is high, and the high speed can be achieved in a short time; accordingly, the distance that the carrier unit 04 moves downward is smaller than the distance that the cable 03 moves downward, and the carrier unit 04 moves upward with respect to the cable 03.
