Embodiment Construction

[0013] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited thereto.

[0014] The invention comprises a propeller rotational motion transmission mechanism, a propeller yaw mechanism and an integral rotary mechanism of an inner sealed cabin. The propeller rotary motion transmission mechanism mainly completes the transmission of the rotary motion of the propulsion motor installed in the inner sealed cabin to the propeller, which can provide propulsion for the underwater robot. The propeller yaw mechanism mainly realizes the yaw movement of the propeller rotation axis around the central axis of the sealed cabin. After a certain angle of deflection, the overall rotation mechanism of the inner sealed cabin will make the propeller rotation axis rotate around the central axis of the sealed cabin by a certain angle. The two kinds of deflection And the rotation movement makes the rotation axis of the prope...

Abstract

The invention discloses a propeller vector propelling device which comprises a propeller rotary motion transmission mechanism, a propeller deflection mechanism and an inner sealed cabin overall rotary mechanism. The propeller rotary motion transmission mechanism is composed of is UPS motion branch chain composed of a U kinematic pair, a P kinematic pair and an S kinematic pair and transmits rotation motion of a propelling motor installed in a sealed cabin to a propeller. The propeller deflection mechanism is composed of a sliding pair composed of a ball screw and an I-shaped guide rail, the mechanism is installed in the inner sealed cabin, and through motion of the lead screw, the propeller deflects around the center axis of the inner sealed cabin. The inner sealed cabin overall rotary mechanism is mainly composed of a pair of inner meshing gear pairs and the inner sealed cabin is driven by rotation of inner meshing gears to rotate within 360 degrees relative to an outer sealed cabin. Through motion synthesis of two independent transmission chains of propeller deflection and inner sealed cabin overall rotation, the propelling device can rotate in all directions at a certain deflection angle. The propeller vector propelling device has the advantages of being convenient to install and control, good in low-speed steering performance and the like.

Description

technical field [0001] The invention relates to the technical field of underwater vehicles, in particular to a propeller vector propulsion device applied to underwater robots. Background technique [0002] At present, the propulsion technology adopted by underwater robots mainly has two schemes: (1) pump jet water jet propulsion, the thrust of which comes from the reaction force of the water jetted out by the water pump. This type of thruster has the advantages of strong cavitation ability, small attachment resistance, good protection, and low noise. However, the water inlet of this propeller is easy to be blocked in waters with a lot of aquatic plants or sundries; and when the speed is low, its propulsion efficiency is lower than that of traditional propellers. (2) Propeller type propeller, the rotation of the propeller causes the water flow to rotate and move backwards, thereby generating the forward movement of the propeller. Only the velocity component parallel to the ...
