Problems solved by technology

From the above-mentioned patents on soft robots: (1) Many of the current soft robots are driven by air pressure. Generally speaking, the air pressure is relatively small, and it is difficult to drive other components or equipment (such as internal in-situ grinding, grasping, etc.) falling debris); (2) For the attitude of the soft robot itself, real-time monitoring cannot be achieved

Embodiment 1

[0037] Embodiment 1: A kind of software intelligent bore detection device and method applied to aero-engine, such as figure 1 The data shown are based on the pressure sensor, temperature sensor and temperature controller data, as the input data of the control system, timely adjust the hydraulic pump supply pressure to drive the guiding structure to move in all directions, and dynamically adjust the camera's pose;

[0038] Among them, the liquid metal is used as the hydraulic medium to drive the deformation of the guiding structure for guidance, and at the same time, the resistance value of the liquid metal between any two measuring electrodes is used, combined with the different deformations of the soft structure layer, resulting in changes in the distance between the measuring electrodes. The distribution of metals also changes.

[0039] In this embodiment, there is liquid metal between any two measuring electrodes, so by measuring the resistance value between any two measuri...

Abstract

The invention discloses a soft intelligent borescope device and method applied to an aero-engine. The soft intelligent borescope device comprises a camera, a guide structure, an extension structure and a control and drive unit. A plurality of elastic cavities are arranged in the guide structure, hydraulic pumps connected with different electromagnetic valves are matched to adjust the bending degree, liquid metal is used for driving the elastic cavities in the circumferential annular array, the pressure intensity of the elastic cavities is controlled to control guide, the working principle is simple and convenient, the multiple measuring electrodes are arranged to obtain the pose of the camera in the working process, an engineer can conveniently control and position a borescope target in real time by means of a digital model of the camera, and the device can also be applied to use scenes of other industrial endoscopes and work of exploration in a human body, has a wider application range, and the method can be used for a hardware foundation and an information source of a digital twinning technology of the aero-engine or an aircraft.

Description

technical field [0001] The invention relates to the technical field of aviation science and technology, in particular to a software intelligent hole detection device and method applied to aeroengines. Background technique [0002] The internal structure damage of the aero-engine occasionally occurs, and the more serious internal structure damage will cause the engine to stop in the air. At present, airlines mainly use the borescope to observe the internal damage of the engine. When the engine is parked on the ground, it is observed with the help of the borehole designed in different structural positions of the engine. The observation results are evaluated in conjunction with the engine maintenance manual, and maintenance is carried out after the evaluation Interval adjustment or immediate repair. [0003] The hole detection technology uses the hole detection equipment as the hardware basis to visually inspect the structural damage inside the engine, and then analyzes it bas...
