Ship model full circle swinging pushing device

Abstract

The invention relates to a ship model full circle swinging pushing device which is composed of an axial transmission mechanism and a circular rotating mechanism. The axial transmission mechanism comprises an upper section inner shaft which is arranged inside an installation base in a penetrating mode, one end of the upper section inner shaft is connected with a first servo motor, the other end of the upper section inner shaft is stretched out of the installation base and is connected one end of a lower section inner shaft, the other end of the lower section inner shaft is connected with a horizontal transmission shaft through a bevel gear, and the horizontal transmission shaft is provided with a propeller. The circular rotating mechanism comprises a circular transmission shaft, the periphery of the circular transmission shaft is connected with a worm gear and a worm, the worm is connected with the output end of a second servo motor, the circular transmission shaft is further connected with one end of an outer shaft through a cover board, and the other end of the outer shaft is matched with a shell on the periphery of the propeller. The ship model full circle swinging pushing device is compact in structure, and small and exquisite in size, can simultaneously achieve axial pushing of the propeller and circular 360-degree rotation of the propeller, meets requirements of installation of models in a water pond, pusher pushing force and locating tests, and obtains good testing effects.

Description

technical field [0001] The invention relates to the field of ship dynamic positioning tests, in particular to a ship model full-rotation propulsion device for ship dynamic positioning tests. Background technique [0002] The dynamic positioning system is a high-tech, high value-added product, and its core technology is completely mastered by a few foreign companies. At present, the domestic technology is still in the stage of exploration and research, and its overall technical level is far from that of foreign countries. In order to break the dynamic positioning system In the situation where the technology is monopolized by foreign countries, it is urgent to develop my country's independent dynamic positioning technology. In order to verify the feasibility of each link of the dynamic positioning system, it is necessary to carry out test debugging and verification. Due to the high cost and long time period of the offshore dynamic positioning system test, so Using the ship model...

AI Technical Summary

Problems solved by technology

[0003] The existing ship model technology is difficult to realize the axial propulsion and circumferential rotation of the propeller at the same time, and the size of the full-turn propulsion device of the ship model is also related to many factors. Condition simulation and other external conditions are demanding. On the contrary, when the volume design is too small, the strength and wear of internal mechanical components cannot meet the requirements of long-term use, and the thrust torque generated is too small to meet the requirements of the test. Cavitation and hydrodynamic distortion are likely to be caused by high-speed rotation, making it impossible to obtain accurate test results
