Manipulator for underwater operation

Abstract

The invention discloses a manipulator for underwater operation. The manipulator structurally comprises a steering rod, a support rod, a base, a holder, a telescopic rod and a joint rod. The steering rod is movably clamped to the upper end position of the support rod. The support rod is welded to the base. One end of the joint rod is connected with the telescopic rod, and the other end of the jointrod is fixedly embedded in the left end position of the steering rod. The holder is mounted at the bottom position of the telescopic rod. A fixing mechanism on the clamping device can fix a sphericalobject. When the clamping block clamps the spherical object, an adsorption mechanism can be contracted inwards by the extrusion force, generated when the spherical object is clamped, on the adsorption mechanism on the fixing mechanism, water in a disc body can be drained through a drainage mechanism on the disc body, and the internal water can be drained through an opening and closing piece on the drainage mechanism when the disc body is extruded by the spherical object and deformed.

Description

technical field [0001] The invention relates to the field of manipulators, in particular to a manipulator for underwater operation. Background technique [0002] The underwater salvage manipulator is mainly used to salvage the sunken objects. It can reach the bottom of the water through the telescopic arm, and then clamp the sunken objects through the gripper at the end, so that the sunken objects can be brought out. The water surface is a common equipment in the salvage industry. Based on the above description, the inventors found that an existing underwater manipulator mainly has the following deficiencies, for example: [0003] Since the underwater salvage manipulator clamps the submerged object through the gripper at the end, when the underwater salvage manipulator salvages the spherical object in salt water, the contact area between the spherical object and the gripper is small, and the The density of water is so high that the water pressure will also be too high. As a...

Problems solved by technology

[0003] Since the underwater salvage manipulator clamps the submerged object through the gripper at the end, when the underwater salvage manipulator salvages the spherical object in salt water, the contact area between the spherical object and the gripper is small, and the The density of water is so high that the water pressure will also be too high, so that when the underwater salvage manipulator salvages spherical objects in this environment, it is easy for the spherical object to fall off before it comes out of the water.
