Active recovery pipe for AUV

Abstract

The invention discloses an active recovery pipe for an AUV. Capturing and dragging mechanisms capable of autonomously moving, capturing the AUV and dragging the AUV into the recovery pipe are arrangedon the recovery pipe. In the recovery process of the AUV, after the recovery pipe enables the head of the AUV to enter a guide cover, the work of an AUV propeller can be stopped, and the problem thatthe AUV recovery process is unstable due to the abrupt change of the hydrodynamic performance of the propeller in the limit drainage basin is avoided. The damage of the AUV to the recovery pipe and an underwater recovery platform is lowered. In the recovery process of the AUV, the AUV is guided into the specified drainage basin through the guide cover. A capturing dragger detects the position ofthe AUV to be recovered and drives capturing magnetic sheets to capture the AUV. After capturing is completed, the dragging mechanisms start to work. Driving gear shafts rotate to drive dragging gearsto drag the capturing dragger to move under the cooperation of recovery pipe guide rails, and the recovery pipe ensures the safety and stability of the recovery process of the AUV through the activerecovery mode; and the recovery work of the AUV is completed.

Description

Technical field [0001] The invention relates to the technical field of AUV recovery, in particular to an active recovery tube for AUV. Background technique [0002] The concept that the 21st century is the century of the oceans was first proposed in 2001 in an official document of the United Nations. The document pointed out that in the next 50 years of human development, the international ocean situation will undergo tremendous changes. The ocean will become the main area of ​​competition for international development, including new economic competition oriented by high-tech. In the context of the development of the times, people are paying more and more attention to the development of marine economy, the development of marine energy, and the protection of maritime rights and interests. Therefore, as the main tool of marine transportation and technology exploration, AUV's design and research value has gradually increased. With the continuous expansion of AUV application field...

AI Technical Summary

Problems solved by technology

However, due to the limited energy carried by the AUV itself, the underwater operation time of the AUV is greatly limited.
