Abstract

The invention discloses a seawater pressure actuator which comprises a shell, a pilot valve and an actuating cylinder, wherein the shell is composed of a left end cover, a right end cover and a cylinder body; the pilot valve is composed of a pilot valve rod, a valve body, a valve plug, a first baffle plate, a second baffle plate and a valve plug spring; the actuating cylinder is composed of a cylinder body, a piston, a piston rod and a restoring spring; the left end cover and the right end cover are fixed at two ends of the cylinder body; the piston rod passes through a through hole at the center of the right end cover and extends out of the actuator; the left end cover, the right end cover, the cylinder body and the piston rod form an enclosed cavity in the cylinder body; and the pilot valve and the actuating cylinder are positioned in the cavity and are fixedly provided with the inner wall of the cylinder body. The seawater pressure actuator can be directly driven by the pressure ofseawater and does not requires external energy sources, simultaneously linear reciprocating movements can be done without any additional mechanical device, and the seawater pressure actuator is suitable for deep sea operating tools requiring linear reciprocating movements, is high in cost performance, and is convenient to carry and operate.

Description

technical field [0001] The invention belongs to the field of deep sea operation, and in particular relates to a linear reciprocating seawater pressure actuator. Background technique [0002] The deep seabed is rich in mineral resources and biological resources. Countries all over the world are competing to conduct exploration activities in the deep sea in physical, chemical and biological conditions to provide scientific data for the development of mineral resources in the future. [0003] The actuators used in existing deep-sea operation tools are often driven by deep-water motors or hydraulic motors, such as a three-phase DC brushless deep-water motor disclosed in the invention patent with the publication number CN101540535, and the utility model patent with the publication number CN2864188 Disclosed is a seawater resistant hydraulic motor. [0004] When using a deep-water motor or a hydraulic motor as the driving device of the actuator, the deep-water motor or hydraulic ...
