This utility model relates to the field of shipbuilding and provides a giant cover plate structure and support assembly for VLEC gas carriers. The cover plate structure includes a cover plate section and a support section. The support assembly includes ground supports that cooperate with the two support sections respectively and support frames that cooperate with the cover plate section. By placing a pair of channel steels on the ground in the construction area and fixing the pair of channel steels with flat steel, the stability and accuracy of the support are ensured. The pair of channel steels clamp the two bottom sides of the support section of the cover plate structure to achieve positioning and limitation, preventing deformation during placement. Two rows of symmetrical support frames support the cover plate section of the cover plate structure, preventing deformation of the pot-shaped cover plate structure during placement, ensuring the precision control of the giant section. The ground supports and support frames can be reused, saving construction costs.

This utility model discloses a stock solution injection pump, including a pump housing, a drive mechanism, and a pump piston. The pump housing has a pump inlet and a pump outlet. The pump piston is driven by the drive mechanism to move up and down in the pump housing. It also includes a limit detection mechanism, which includes an upper limit detection sensor, a lower limit detection sensor, and a detection strip. The detection strip moves up and down synchronously with the pump piston and cooperates with the upper and lower limit detection sensors. This utility model has the advantages of simple structure, good liquid flow rate accuracy control, and improved working reliability.
