Embodiment Construction

[0053] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0054] as attached figure 1 As shown, an underwater soft arm made of silicone rubber for AUV recovery includes a composite unit 1 with telescopic and bending functions and a bidirectional torsion unit 2 . There are five cylindrical cavities 3~7 in the telescopic and bending composite unit, and a number of 90° circular arc grooves arranged along its axial direction are symmetrically arranged on the outside, and are symmetrically distributed with respect to the central section of the composite unit; unit 1 and Unit 2 is fastened together. The two-way torsion unit is located below the telescopic and bending compound unit, and contains two helical cavities 9 and 10 with a difference of 180° in the ...

Abstract

The invention discloses an underwater flexible arm and an AUV (Autonomous Underwater Vehicle) underwater flexible recovery mechanism. The underwater flexible arm comprises a composite unit, a torsion unit, a two-way pump, a three-position three-way valve, a motor and a control unit, the composite unit and the torsion unit are fixedly connected and are made of a flexible material; a spiral cavity with an opening in one end is formed in the torsion unit; at least five cylindrical cavities of which one ends are opened are formed in the composite unit; two-way pumps and three-position three-way valves are arranged at the opening ends of the spiral cavities and the cylindrical cavities; the two-way pump is driven by a motor; the control unit controls the motor and the three-position three-way valve, and the same-form rigidity changing function of the underwater flexible arm is achieved. The AUV underwater flexible recovery mechanism comprises a bottom plate and a long arm unit. Each long arm unit is composed of at least two underwater flexible arms which are connected in series end to end. According to the underwater flexible recycling mechanism, the AUV can be recycled in a flexible contact mode, and the water leakage risk caused by connection collision of the AUV is avoided.

Description

technical field [0001] The invention relates to the technical field of underwater vehicles, in particular to an underwater flexible arm and an AUV underwater flexible recovery mechanism. Background technique [0002] Autonomous underwater vehicle is a kind of ocean mobile observation platform. It has no cables and does not require human operation. It can autonomously navigate into areas where the submarine observation network cannot be deployed for observation. However, AUVs are usually powered by batteries, so the energy they carry is very limited, and they cannot conduct long-term continuous underwater observation. [0003] In order to improve the underwater observation time of AUV, scientific research institutes at home and abroad have begun to study AUV connection technology, that is, to recover AUV through a bottom-seat connection base station with bell mouth entrance, but the rigid structure of this recovery device will be in the AUV Collision damage to the AUV head d...
