[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] The embodiment of the invention discloses an underwater automatic rotating device of an acoustic array.

[0017] The present invention provides Figure 1-6 An acoustic array underwater automatic rotation device shown in the figure includes an N-type bracket 2, a connecting plate 5, an electric control box 6, an operation panel 7 and a roll force module 9. A roll bracket 8 is provided on the N-type bracket 2, a stainless steel bearing 4 is installed on the connecting plate 5, and the connecting plate 5 is rotatably connected to the roll bracket 8 through the stainless steel bearing 4. An XY translation mechanism 1 is provided on the top of the N-type bracket 2. The XY translation mechanism 1 consists of two electric push rods arranged in the XY direction, and mounting plates are provided on the extending ends of the two electric push rods.

[0018] An acoustic array underwater automatic rotation device of the present invention has a stainless steel arc-shaped rack on the connecting plate 5, and a roll force module 9 includes a shell and a motor. The shell is installed on the outer wall of the roll bracket 8 through a frame, and the motor is installed inside the shell. The output end of the motor passes through the shell and is fixedly connected with a gear through a coupling. The gear and the stainless steel arc-shaped rack are meshed and connected, which can facilitate the connection plate 5 to rotate stably and achieve the corresponding use effect.

[0019] In an acoustic array underwater automatic rotation device of the present invention, the electric control box 6 is connected to the XY translation mechanism 1, the operation panel 7 and the rolling force module 9 through wires, which can facilitate the control of the operation of related equipment and improve the convenience of use.

[0020] In an underwater automatic rotation device of an acoustic array of the present invention, a waterproof angle encoder 3 is installed on an N-type bracket 2, and an electric control box 6 is connected to the waterproof angle encoder 3 through electric wires, which can accurately ensure the rotation angle and improve the measurement accuracy of the overall equipment.

[0021] In the underwater automatic rotating device of an acoustic array of the present invention, the XY translation mechanism 1 and the rolling force module 9 are both waterproof structures, which can avoid the phenomenon of being unable to be used due to water ingress and improve the overall service life.

[0022] In the underwater automatic rotating device of an acoustic array of the present invention, the connecting plate 5 is provided with a plurality of screw holes in a ring shape, so as to facilitate fixing the product to be tested on the connecting plate 5 .

[0023] When in use, the upper end of the XY translation mechanism 1 is connected to the flange at the end of the suspension rod of the water pool walking device (the walking device is a prior art and will not be elaborated on here), and then the sealing cover plate at the tail end of the product to be tested is connected to the connecting plate 5 by bolts. After the connection is completed, the gear can be driven to rotate by the motor. Since the gear is meshed with the stainless steel arc rack, the connecting plate 5 can be driven to rotate, thereby driving the product to be tested to rotate and realizing multi-angle rotation operation. Through the operation of the XY translation mechanism 1, the X / Y axis translation movement can be realized to compensate for the position deviation in the four directions of front, back, left and right after the product to be tested is rotated. Through the above method, the accurate directional positioning test of the acoustic array and the array to be tested at different positions can be realized, which reduces the labor intensity of workers, saves the loading and unloading time of the product to be tested, and improves the test efficiency.
