Underwater charging connection mechanism

Abstract

The object of the present invention is to provide an underwater charging connection mechanism, which includes a short-contact linear auxiliary mechanism of the inner and outer cylinders, a self-formal hollow spherical hinge mechanism, and a spring force retention mechanism. The mechanism uses a hydraulic cylinder or other linear drive mechanism as a power source, and through designing and rationally arranging springs, selecting a suitable type of self-lubricating radial joint ball bearing and designing the length of the hollow bearing shaft, the self-formal hollow bearing with tilt self-adaptive ability The spherical hinge mechanism drives the charging interface plane of the transmitter of the magnetic coupling charging device to closely fit the charging interface plane of the receiver on the underwater robot, and the spring force retention mechanism ensures a certain bonding force for a long time. The charging joint of the present invention can passively adjust its own posture to adapt to the angle deviation between the docking device and the AUV charging interface, and ensure the accuracy of the connection between the charging joint and the charging interface.

Description

technical field [0001] The invention relates to a docking mechanism, specifically an underwater docking mechanism. Background technique [0002] During the use of various underwater robots, especially the use of autonomous underwater vehicles (AUV for short), due to the limitation of their own energy, they usually need to be frequently salvaged to the shore for charging and data exchange. Using the underwater charging method, that is, by connecting the AUV charging interface with the charging connector of the underwater docking device for energy supplementation, can solve frequent salvage work, reduce the consumption of manpower and material resources, and improve the working efficiency of underwater robots. When the AUV is locked in the underwater docking device, there will be an angular deviation between the charging interface on the AUV and the charging connector on the docking device. This deviation is difficult to eliminate, so design a charging connection that can adap...

Problems solved by technology

The Monterey Bay Aquarium Research Institute designed a dual-pin-guided connection mechanism for the connection between the AUV and the charging connector of the docking device. The charging mechanism consists of a pair of metal structure guide pins and a charging connector. The whole mechanism is installed on the linear drive mechanism, and the guide pin is inserted into the guide hole on the AUV to drive the connection between the charging connector and the AUV charging interface. When there is a large position deviation of the charging connector of the docking device, the connection action cannot be performed

The patent document with the patent number "00242747.8" introduces a charging connection mechanism applied to computers, which is characterized in that the interface of the charging stand can be replaced and can adapt to two types of connectors; the mobile robot with the application number "200820020341.5" charges The connector introduces a mechanism that drives the movement of the charging connector through the rack and pinion mechanism driven by the motor. It is characterized in that it can solve the problem of virtual connection of the charging connector. The above two mechanisms do not involve the angle deviation when the charging connector is connected to the charging interface. question
