UNDERWATER WORKING ROBOT

摘要

The present invention relates to an underwater working robot. The underwater working robot comprises: a main body where a buoyancy device for having neutral buoyancy is installed at one side thereof; a driving device which is installed in the main body and can move along the surface of an object by including multiple wheels; an adsorption pad which is installed in the lower part of the main body, is connected with a vacuum pump through piping, and sucks water through the vacuum pump in order to have adsorptive power with the surface of the object; and multiple ball transfers which are installed in the lower part circumference of the adsorption pad. The provided underwater working robot can perform work such as cleaning on a wall surface through smooth movements by being adsorbed onto the wall surface of a swimming pool using the vacuum pump and the adsorption pad. To be more particular, the underwater working robot can avoid the separation from the wall surface and maintain work by having vacuum power of a fluid due to the suction pressure of the vacuum pump, can operate by adhering to the wall without any influence of the self weight by installing the buoyancy device in the main body in order to have neutral buoyancy under the water, and can increase suction power by enlarging a pressure difference between the inside and the outside of the adsorption pad, by minimizing the gap between the adsorption pad and the surface of the object through the installation of a gap regulating unit protruding downward on the lower part circumference of the adsorption pad. The buoyancy of the buoyancy device can be regulated by a regulating valve in order to smoothly maintain the neutral buoyancy state according to changes in the water depth or the robot weight.
