Mobile underwater monitoring device with floating platforms

Abstract

The invention discloses a mobile underwater monitoring device with floating platforms. The device comprises an above-water floating platform, an underwater cradle head and an anchor body. The above-water floating platform comprises two floating platforms, watertight motors and reduction gearboxes, wherein the two floating platforms are opposite to each other; the watertight motors are oppositely and fixedly arranged on the floating platforms; the reduction gearboxes are arranged on the watertight motors, and are connected with an anchor cable capstan and a lifting capstan; anchor cables are wound on the anchor cable capstan; underwater cables are wound on the lifting capstan. The underwater cradle head comprises an underwater cradle head bracket, a plurality of grooved pulleys, a cradle head, an underwater illumination lamp and an underwater camera, wherein the grooved pulleys are arranged on the underwater cradle head bracket; the cradle head is fixedly arranged on the underwater cradle head bracket; the underwater illumination lamp and the underwater camera transmit signals through the underwater cables; the anchor cables are connected between the grooved pulleys. The anchor body comprises a bottom anchor and the anchor cables, wherein the anchor cables are fixedly arranged on the bottom anchor; the bottom anchor is connected with the above-water floating platform through the anchor cables. According to the device, visual areas for underwater monitoring can be added, and the problem of image instability of a conventional underwater device is solved; moreover, the structural design is simplified, and the production and maintenance cost is lowered.

Description

technical field [0001] The invention relates to an underwater monitoring device, in particular to a mobile underwater monitoring device with a floating platform for workers to monitor an underwater test scene. It belongs to the field of offshore oil engineering. Background technique [0002] At present, there are mainly two types of devices for monitoring underwater test scenarios: one is mobile and the other is fixed. Among them, there are also two kinds of mobile underwater monitoring devices, one is the propulsion mobile type, which mainly includes: underwater robot (ROV), underwater autonomous robot (AUV), among them, the underwater robot (ROV) is connected with the umbilical cable Surface vessels exchange energy and data signals. Screw propellers are installed on the front, rear, left, and right sides of the ship, which can move within the range of the umbilical cable. The front of the underwater robot (ROV) is equipped with lights, cameras and mechanical arms for oper...
