Universal unmanned underwater vehicle recovery device and recovery method

Abstract

The invention discloses a universal unmanned underwater vehicle recovery device and recovery method, and relates to the technical field of underwater robot recovery. The device comprises a cage and atop cross beam. A first lifting lug, a second lifting lug, a guide cable pulley and a camera cable storage box are mounted on the top cross beam, and the top cross beam and the cage are fixedly connected to form a recovery lifting cage. A front fence and a rear fence are arranged at the two ends of the cage correspondingly. A left eye camera and a right eye camera are mounted on the two sides of an inlet of the cage. A top camera is mounted at the top of the inlet of the cage. A T-shaped groove is formed in the bottom of a middle cross beam of the top cross beam. A spherical hinge structure isin sliding connection in the T-shaped groove. The top cross beam is connected with hose clamps through the spherical hinge structure. The universal unmanned underwater vehicle recovery device and recovery method have the advantages that the two work modes of water recovery and underwater recovery are achieved, the proper work modes can be selected according to different work sea conditions, and work efficiency is improved; and the problem of high danger of release and recovery work of unmanned underwater vehicles can be solved.

Description

technical field [0001] The invention relates to the technical field of underwater robot recovery, in particular to a universal unmanned submersible recovery device and recovery method. Background technique [0002] With the development of science and technology, there are more and more explorations of marine resources. As the main exploration tool, unmanned submersibles need to recover and collect data after completing operations. However, the marine environment is complex and changeable, especially in harsh sea conditions. The recovery of unmanned submersibles has become very difficult. [0003] There are two main recovery methods. The first one is that the staff take a small boat close to the unmanned submersible, dock with the artificially assisted lifting device, and complete the recovery. This recovery method is greatly affected by wind and waves, and the risk factor is poor when the sea condition is poor. High, it is easy to cause injury to staff and equipment; the se...

[0002] With the development of science and technology, there are more and more explorations of marine resources. As the main exploration tool, unmanned submersibles need to recover and collect data after completing operations. However, the marine environment is complex and changeable, especially in harsh sea conditions. The recovery of unmanned submersibles has become very difficult

[0003] There are two main recovery methods. The first one is that the staff take a small boat close to the unmanned submersible, dock with the artificially assisted lifting device, and complete the recovery. This recovery method is greatly affected by wind and waves, and the risk factor is poor when the sea condition is poor. High, it is easy to cause injury to staff and equipment; the second is to use floating docks and lifting platforms for underwater docking recovery, which can reduce the impact of wind and waves, but small floating docks have weak wind and wave resistance, and large floating docks The cost is high, the mother ship needs special support, the recycling fee is expensive, and it is not suitable for popular use
