AUV underwater docking propeller performance test experimental device applied to pool laboratory

Abstract

The invention provides an AUV underwater docking propeller performance test experimental device applied to a pool laboratory. The AUV underwater docking propeller performance test experimental deviceincludes a pool, an underwater docking base station, an AUV propeller installation and movement system and a data display and preservation system. The underwater docking base station is mounted on theinner wall of the pool through a third rigid connection rod and a cantilever beam; an annular six-component mechanical sensor is connected with a propeller and a hollow transmission shaft, a second rigid connection rod passes through the inside of the hollow transmission shaft, an AUV tail structure is in rigid connection with a gear sealing cabin, and cross beams striding the two sides of the pool are fixedly connected together through a first rigid connection rod. The cross beams are driven by a travelling wheel, and the relative distance between the propeller and an underwater docking device can be changed; the first rigid connection rod is axially telescopic, to change the vertical position of the propeller; the joint of the first rigid connection rod and the cross beams can move laterally; a rotating shaft in each cross beam and the first rigid connection rod can rotate to control the attitude angle of the propeller in the underwater docking process, and thus the testing of the mechanical property of the propeller during the docking is achieved.

Description

technical field [0001] The invention relates to the technical field of AUV underwater performance testing, in particular to an AUV underwater docking propeller performance testing experimental device applied in a pool laboratory. Background technique [0002] Autonomous Underwater Vehicle (AUV) is currently playing a very important role in both military and civilian fields. People's requirements for AUV are getting higher and higher, with large range, high speed, strong maneuverability and high reliability. Become an important technical indicator of AUV. However, due to the limitation of the energy that AUV can carry, the underwater operation time of AUV is greatly affected. Therefore, all countries are currently studying AUV underwater docking technology to improve the operation time and efficiency of AUV. [0003] During the underwater docking process of AUV, there are three motion states of exiting the pipe, entering the pipe, and moving inside the pipe. In these three m...
