Abstract

The invention provides an engineeringship logindicator protection cover and belongs to the technical field of ship accessories. The engineeringship logindicator protection cover comprises a first sliding block, a support, a controller, a first cover body, a second sliding rail, a second sliding block, a second air cylinder, third sliding rails, a first folding cover, third sliding blocks, a second folding cover, a first air cylinder, a supporting frame, a supporting column, a first sliding rail, a second cover body, a first rack, a first machine base, a first motor, first blades, a first spring, a first fisheye bearing, a third air cylinder, a first flexible plate, a fourth air cylinder, a second fisheye bearing, a second flexible plate, a second spring, second blades, a second machine base, a second motor and a second rack, wherein the first cover body is installed below the support, the second sliding rail is installed at the top of the first cover body, the second sliding block is installed on the second sliding rail, two third sliding rails are installed on the side face of the first cover body, the third sliding blocks are installed on the third sliding rails, and the second cover body is installed on the third sliding blocks and the second sliding block. The engineeringship logindicator protection cover has the advantages of avoiding a logindicator against damage caused by air bubbles.

Description

technical field [0001] The invention relates to a protective cover for a speed log of an engineering ship, which belongs to the technical field of ship equipment. Background technique [0002] During the voyage of the ship, the speed and cumulative voyage are usually measured by Doppler log. The working principle of the Doppler log is: use the Doppler frequency shift between the emitted sound wave and the received underwater reflected wave to measure the ship's speed and cumulative voyage relative to the bottom of the water. Log transducers are usually installed in the bow area of ​​the ship. When the ship is sailing, when the water pressure somewhere in the bow drops below the critical value, it will cause explosive vaporization, and the water vapor will enter the gas core through the interface and make it expand to form bubbles, which will easily damage the log. In order to solve the above difficulties, it is necessary to develop a shield for the engineering ship's log t...
