Electric cylinder used for deep sea environment

Abstract

The invention discloses an electric cylinder used for a deep sea environment, and relates to the field of an electric cylinder. The electric cylinder comprises an execution mechanism and a power mechanism; the execution mechanism and the power mechanism both adopt a sealed structure, and the execution mechanism and the power mechanism are sealed mutually; the execution mechanism comprises an outershell, a guiding inner shell, a push rod and a trapezoid lead screw; the guiding inner shell is positioned in the outer shell; one end of the push rod is inserted in the guiding inner shell while theother end is positioned on the exterior of the guiding inner shell; one end of the trapezoid lead screw is connected with the driving execution mechanism while the other end is inserted in the push rod; one end, closes to the interior of the inner shell, of the push rod is connected with the trapezoid lead screw through a nut; the nut is used for converting a rotary motion of the trapezoid lead screw into a reciprocating linear motion and driving the push rod to perform the reciprocating linear motion; and one end, far from the power mechanism, of the push rod can extend out of the outer shell to perform a reciprocating motion. The electric cylinder can bear deep sea high pressure, avoid ocean current interference and can be used as normal for a long term in the deep sea environment.

Description

technical field [0001] The invention relates to the field of electric cylinders, in particular to an electric cylinder used in deep sea environments. Background technique [0002] The electric cylinder is a modular product that integrates the rotating motor and the trapezoidal screw. The motor drives the trapezoidal screw to rotate, and the nut converts the rotational motion of the motor into a reciprocating linear motion, and connects the electric cylinder to a control system such as PLC. The control system controls the rotation of the motor, which can realize high-precision motion control, energy saving, clean, and easy operation and maintenance. [0003] At present, most actuators are driven by hydraulic cylinders in the deep sea environment. However, due to the complexity of the marine environment, the strong corrosion of seawater, and the high pressure in the deep sea, the hydraulic cylinders are easily damaged and the cost of use is high; Cylinders are also difficult ...

Problems solved by technology

[0003] At present, most actuators are driven by hydraulic cylinders in the deep sea environment. However, due to the complexity of the marine environment, the strong corrosion of seawater, and the high pressure in the deep sea, the hydraulic cylinders are easily damaged and the cost of use is high; Cylinders are also difficult to withstand high pressure, mechanical parts are easily radiated by seawater, and are easily affected by ocean currents, making it difficult to use in deep sea environments on a large scale
