Embodiment Construction

[0023] Attached below Figures 1 to 4 The present invention is described in further detail.

[0024] Such as figure 1 As shown, a novel underwater equipment vector thruster of the present invention includes two parts, respectively a propeller drive and a 3-PPS parallel drive mechanism.

[0025] The propeller drive consists of a front propeller 1, a rear propeller 2, a double-rotor underwater motor 3 and a propeller end cover 10.

[0026] The double-rotor underwater motor 3 is a waterproof motor, which has the advantages of small size, pressure resistance, waterproof, corrosion resistance, etc., and has a double-rotor structure. There are two output shafts, which are respectively an inner output shaft and an outer output shaft. The front propeller 1 and the rear propeller 2 are respectively connected with the inner and outer output shafts of the dual-rotor underwater motor 3 through splines or flat keys.

[0027] The output torque of the double-rotor underwater motor 3 drive...

Abstract

The invention discloses a PPS underwater equipment vector propeller. The PPS underwater equipment vector propeller comprises a propeller driver and a 3-PPS parallel driving mechanism; the 3-PPS parallel driving mechanism comprises a movable platform used for being fixedly connected with the propeller driver, a static platform and three PPS driving branched chains arranged between the movable platform and the static platform in parallel. And the two ends of the PPS driving branch chain are movably connected with the movable platform and the static platform correspondingly, the working posturesof the movable platform and the propeller drivers are controlled by adjusting the telescopic length of the PPS driving branch chain, and vector adjustment in the propelling force direction is achieved. The vector propeller adopts a three-degree-of-freedom 3-PPS parallel driving mechanism, has the advantages of being compact in structure and high in rigidity, the propelling posture of the propelleris flexibly adjusted, and the control maneuverability and flexibility of underwater equipment are greatly improved.

Description

technical field [0001] The invention relates to the field of underwater navigation and detection equipment, in particular to a vector thruster for underwater equipment, which is used for vector propulsion of underwater equipment. Background technique [0002] Underwater navigation and detection equipment is an important tool for my country's ocean development, and the propeller is one of the key components of underwater navigation and detection equipment. It provides thrust in different directions to ensure that underwater navigation and detection equipment advance in a predetermined direction. . At present, most underwater vehicles and detection equipment use a propeller with a single motor and a single propeller, and the motor directly drives the single propeller to achieve power output. This traditional thruster has a single attitude and low propulsion efficiency, especially when the underwater equipment is running at a low speed, the manoeuvrability and flexibility of th...
