Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only the part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area
All other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
Referring to Fig. 1, one kind opens body hopper oil vat for vessel water-tight device, oil cylinder both ends are connected to hull or so halfbody
Go up and drive halfbody 10 to open or close, oil cylinder includes cylinder body 1, the piston 2 in cylinder body, the piston being connected with piston 2
