Underwater electric manipulator with open structure

Abstract

The invention relates to the related technical field of electric manipulators, in particular to an underwater electric manipulator of an open structure which comprises a connecting end, and a first power source is arranged on the connecting end; the underwater electric manipulator further comprises at least one set of lead screws, and one set of lead screws is connected with the connecting end through the first power source; every two adjacent sets of lead screws are connected through a second power source, and a lead screw nut is further arranged on each lead screw; the lead screw nut of the lead screw at the tail end is connected with a paw connecting rod through a nut base; the manipulator further comprises a paw, and the bottom end of the paw is connected with the lead screw through a second rotating shaft; and the paw is connected with the paw connecting rod through a first rotating shaft. The manipulator has the beneficial effects that the underwater manipulator is simple in structure, parts are fewer than those of a manipulator in the prior art, the maintenance is more convenient, and therefore the underwater manipulator has extensive value in promotion and application.

Description

technical field [0001] The invention relates to the technical field related to electric manipulators, in particular to an open-structure underwater electric manipulator. Background technique [0002] Manipulators are mechanical equipment widely used in industry and scientific research, and the existing manipulators are relatively mature. In recent years, the trend of exploring the ocean has intensified, and manipulators suitable for underwater use are rare. The current underwater electric manipulator is to place the DC motor in the sealed casing to be waterproof, and the manipulator claws are exposed to the water outside the sealed casing. The internal motor realizes the connection with the external mechanical claw mechanism through the transmission shaft. At the connection between the drive shaft and the gripper mechanism, sealing means must be used to prevent external water from penetrating into the sealed housing of the motor. [0003] However, the existing underwater ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing underwater electric manipulator has the following disadvantages: 1. The dynamic seal of the transmission shaft has always been the key technology of the underwater electric manipulator, and the failure rate of the underwater electric manipulator due to the sealing has always been high

The heat generated when the DC motor is working needs to be transferred to the sealed casing first, and then transferred to the external environment by the sealed casing, resulting in a decrease in heat conduction efficiency; 3. The existing manipulator adopts a two-piece gripper to grasp The operation is more complicated when taking irregular objects; the form of the manipulator is fixed, and the entire manipulator needs to be replaced for different tasks
