Abstract

The invention provides a mounting method of an acoustic log, which comprises the following steps of: A, introducing a corrected ship body center line into a mounting cabin, marking a straight line vertical to a bow and stern marker line at a mounting rib position, and marking a base mounting center on the cabin ground; B, aligning the center of a base with the marked base mounting center, aligningthe bow and stern line of the base with the bow and stern marker line on the cabin ground, and then welding the base to the cabin ground; C, checking the mounting quality of the base, and ensuring that the mounting direction of the base meets the precision requirement; and D, placing the acoustic log in the base, and completing sealed installation of the acoustic log. The mounding method of the acoustic log has the beneficial effects that the mounding method of the acoustic log is provided, the problems that in the prior art, a rod type sensor of an electromagnetic log extends out of the bottom of a ship for speed measurement, seaweeds are prone to being hooked, breaking is caused, and the rod type sensor is prone to being affected by turbulent flow are solved, and the acoustic log can provide the speed to the ground and the transverse moving speed of the ship; and the navigation precision of ship navigation equipment is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an installation method of an acoustic log. Background technique [0002] In the middle of the 20th century, as a new type of navigation instrument, the electromagnetic log was widely used in the ship navigation system, providing the ship's speed on the water when it was moving forward and backward, and assisting in measuring the ship's voyage. With the emergence of large ships and other navigation and positioning requirements, ships not only need to obtain the forward and reverse water speed, but also need to obtain the ship's ground speed and traversing speed through the navigation system when the ship enters and leaves the port and berths at the dock. In order to meet the new requirements, the acoustic log was developed and then added to the ship navigation system. The speed measurement principle of the acoustic log is as follows: the transducer transmits an acoustic puls...
