Electromagnetic automatic line throwing appliance for recycling underwater robot

Abstract

The invention relates to the field of underwater robots, in particular to an electromagnetic automatic line throwing appliance for recycling an underwater robot. The electromagnetic automatic line throwing appliance for recycling the underwater robot comprises an electromagnet, a spring clamping ring, a cable, an end cover, a buoyancy block, a launching tube, a bottom steel plate, a spring and a base, wherein the base is fixedly mounted on an underwater robot main body; the launching tube is fixedly mounted on a flange of the base; the electromagnet is arranged in the launching tube and controlled by a control system of the underwater robot main body to be powered on and off; the electromagnet is filled with oil to balance external pressure; the bottom steel plate is arranged in the launching tube and adsorbed by the electromagnet; the spring sleeves the electromagnet; the spring pushes the bottom steel plate and each part above the bottom steel plate out of the launching tube through the spring clamping ring; the cable and the buoyancy block are arranged in the launching tube, within a space between the end cover and the bottom steel plate; one end of the cable is fixedly connected with the bottom steel plate; and the other end of the cable is connected with the underwater robot main body after being led out from the launching tube. The electromagnetic automatic line throwing appliance has the advantages of convenient operation, small size and low cost and can bear deep sea water pressure for a long time.

Description

technical field [0001] The invention relates to the field of underwater robots, in particular to an electromagnetic automatic rope thrower for recycling underwater robots. Background technique [0002] The recovery technology of underwater robots is one of the important factors that limit the development of underwater robots. In the past, the recovery of underwater robots required professionals to take small boats to the water surface to complete the recovery operation, which was relatively dangerous. In order to make it unnecessary for professionals to take a small boat to the water surface to recover the underwater robot, the existing technology enables the underwater robot to automatically throw out the cables on the water surface, and the professionals on the mother ship salvage the cables and perform corresponding recovery operations. The rope throwing devices in the prior art generally use pyrotechnic devices and high-pressure gas cylinders as the power source. Due to ...

AI Technical Summary

Problems solved by technology

The rope throwing devices in the prior art generally use pyrotechnic devices and high-pressure gas cylinders as the power source. Due to the high pressure in the deep sea, most of the rope throwing devices cannot be used underwater, and a few of the pyrotechnic device rope throwing devices that can be used underwater Then there are defects such as high cost, cumbersome operation, and greater influence of individual differences in pyrotechnic products.
