Magnetic abutting device of ROV and operation tool library

Abstract

The invention relates to a magnetic abutting device of a ROV and an operation tool library. The magnetic abutting device is used for mechanical, hydraulic or circuit connection between the ROV and theoperation tool library. The abutting device comprises an upper module and a lower module, wherein the upper module and the lower module are respectively fixed on the ROV and the operation tool library by a framework, a guide mechanism, a magnetic lifting device, a magnetic induction electrical connector and a magnetic coupler are arranged on each of the two modules, the guide mechanisms are usedfor adjusting a position before abutting, the magnetic lifting devices automatically suck to each other so that a ROV body and the operation tool library are connected, the magnetic induction electrical connectors are abutted to achieve electrical energy and control signal transmission, and the magnetic couplers are connected so that a motor on the ROV drives a hydraulic pump of an operation toolbox. Compared with the prior art, the magnetic abutting device has the advantages that the abutting gap is relatively large, abutting stuck is prevented, a plug is not needed to be plugged out by a wet hand, the reliability is improved, and the economic cost is reduced; the modular design of the abutting device is applicable to various tool libraries, and the abutting device is convenient to replace and install and simple to operate.

Description

technical field [0001] The invention relates to the technical field of underwater operations, in particular to a magnetic docking device for an ROV and an operating tool magazine. Background technique [0002] ROV is a remotely controlled unmanned submersible, an underwater robot used for underwater observation, inspection and construction. In order to improve the operating capability and efficiency of ROV, a fixed operating tool magazine has been adopted at present. The tool magazine is usually mounted under the ROV and fixedly connected to the ROV. During operation, it is necessary to manually connect the ROV to the operation tool library mechanically, hydraulically or electrically, which greatly affects the efficiency of ROV operation. The existing automatic connection technology between ROV and operation tool storage mainly uses underwater wet plug joints to realize the circuit and hydraulic connection between tool storage and ROV. This method is limited by underwater w...

Problems solved by technology

Environmental factors such as seawater corrosion, sediment, and marine organism adhesion will largely lead to the failure of wet-plug connectors. In addition, wet-plug connectors exposed to seawater for a long time will reduce the success rate of underwater plug-in.

Wet-plug connectors are expensive, have a short service life, need to be replaced frequently, and have high economic costs
