As a further solution of the present invention, the first ball head is rotatably connected to the first ball seat, and the second ball head is rotatably connected to the second ball seat.

As a further solution of the present utility model, the electric telescopic rod and the connection structure form a steering assembly, and the steering assembly is provided with three groups, and the three groups of steering assemblies are equidistant circular arrays.

As a further solution of the present utility model, each group of the steering components is composed of two electric telescopic rods and a connecting structure, one of which is inclined at 10-20° in the horizontal direction, and the other electric telescopic rod is in the horizontal direction 20-40° tilt setting.

As a further solution of the present utility model, the tip of the driving paddle is arranged in a "bullet-shaped" structure, and the size of the base and the top seat are the same.

The beneficial effects of the utility model are as follows: the movement of the position of the top seat is controlled by the extension and shortening of the six electric telescopic rods, and then the control of six degrees of freedom is realized, and the multi-directional propulsion effect of the single propeller is realized by combining the vector motor with the drive paddle, Compared with the traditional method that requires multiple steering gears to adjust the direction, it is simpler, faster, and has higher precision, and only one or more electric telescopic rods can be used to achieve the direction adjustment during work, and the operation is simpler.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Figure 1-3, an underwater vector thruster includes a base 1 and a top seat 2. The upper part of the top seat 2 is equipped with a vector motor 4 through a flange 3, and one end of the shell of the vector motor 4 is installed with a protective cover. Cover 6, the output shaft of vector motor 4 is positioned at the inner side of guard cover 6 and drive oar 5 is installed, is provided with electric telescopic link 7 between base 1 and top seat 2, and the two ends of electric telescopic link 7 are connected with base 1 and top seat respectively. 2 is provided with connecting structure 8.

In this embodiment, the connection structure 8 includes a first ball seat 9 and a second ball seat 11, the first ball seat 9 is installed on the upper part of the base 1, the second ball seat 11 is fixedly installed on the bottom of the top seat 2, and the electric telescopic rod A first ball head 10 and a second ball head 12 are mounted on both ends of 7 respectively.

The base 1 and the top seat 2 are respectively connected to the electric telescopic rod 7 through the first ball seat 9 and the second ball seat 11, so when the electric telescopic rod 7 is in telescopic work, it can cooperate with the first ball head 10 and the second ball joint The head 12 turns.

In this embodiment, the first ball head 10 is rotatably connected to the first ball seat 9 , and the second ball head 12 is rotatably connected to the second ball seat 11 .

The first ball seat 9 cooperates with the first ball head 10 , and the second ball seat 11 cooperates with the second ball head 12 so that the base 1 and the top seat 2 can be adjusted at multiple angles at both ends of the electric telescopic rod 7 .

In this embodiment, the electric telescopic rod 7 and the connection structure 8 form a steering assembly, and there are three sets of steering assemblies, and the three sets of steering assemblies are equidistant circular arrays.
