Abstract

The invention belongs to the technical field of underwater bio-robot ejection devices and aims to provide a vacuum-like ejection device with the simple structure, small size and low cost. A closed space is formed by a piston, a pump, a sealing nut and an adjusting nut. A motor is used for driving a limiting gear to rotate through a transmission unit, and a piston rod is pulled to move backwards, so that the gas volume in the closed space is increased, and the pressure intensity is decreased. When the piston rod reaches a preset position, the piston rod is locked by a spring armature. During ejection, the spring armature is sucked upwards through an electromagnetic mechanism to loosen the piston rod, the piston rod rapidly returns to an initial position under the atmospheric pressure, and movement of the piston rod acts on an ejected light object to achieve the ejection purpose. The atmospheric pressure principle is used, effective control over ejection can be achieved, and continuous ejection can be achieved. The vacuum-like ejection device can achieve tasks such object transferring and carrying in actual application of underwater robots and mutual cooperation of multiple robots.

Description

technical field [0001] The invention belongs to the technical field of underwater bionic robot ejection devices, in particular to a kind of vacuum ejection device. Background technique [0002] At present, there are many kinds of ejection devices used by robots, including rail-type launching devices, drop-type launching devices, suspension devices, connecting launching devices, spring ejecting devices, etc., which can be pneumatic or electromagnetic. Iron etc. as power. The spring device adopts Hooke's law. CN101870350A discloses a crank type ejection device, which uses a motor to drive a bevel gear to drive the crank mechanism, and uses the crank device to compress the spring, release the compression energy of the spring at an appropriate position, and make the spring force act on the object to complete the ejection purpose. The above devices are generally large in size or relatively high in cost, and do not meet the performance requirements of the underwater robot on the...
