Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

As shown in fig. 1-5, a ship deck flatness detection device, a box assembly 1 can facilitate installation of internal components of the device, a cover plate 2 can fixedly seal a rubber shading block 6 and an insertion strip 7, a through groove 3 and an L-shaped groove 4 can facilitate up-down movement of the rubber shading block 6 and the insertion strip 7, the insertion strip 7 can be inserted in the insertion groove 5, a mounting strip 11 can facilitate installation of a laser lamp 12 in the device, the laser lamp 12 can emit laser, thereby facilitating marking of detected deck unevenness, a groove 13 can facilitate passing of the laser emitted by the laser lamp 12 after the rubber shading block 6 moves downwards, a battery compartment 14 can provide power for the laser lamp 12, the rubber shading block 6 can shade the laser emitted by the laser lamp 12, so that the laser cannot pass through the rubber shading block 6 when the deck is flat, supporting wheel 19 bottom can detect the unevenness of deck, and the installation of fixed plate 9 and spring 10 can be made things convenient for to the inside of opening 8, and inserting groove 5 can carry on spacingly to the top of fixed plate 9, and under spring 10's elastic support, thereby the bottom of spring 10 is fixed can support grafting strip 7 downwards with inserting groove 5's inside.
