Description

Fan connecting tooling and cabin exhausting device

Technical field

The utility model relates to the technical field of ship construction, in particular to a fan connecting tooling and a cabin exhausting device.

Background technique

During the construction of the ship, in the limited working space such as the engine room, ballast tank, and narrow closed compartment, due to the large amount of exhaust gas generated during the assembly, electric welding and carbon planing, the working environment of the site and the personal health of the constructor Bringing greater damage. In order to better discharge the exhaust gas generated during the operation, the current method is to arrange more fans in the cabin and pull the air duct into the cabin, to increase the fresh air to “crowd out” the exhaust gas, and to increase The air flow in the work area is used to achieve the discharge of the exhaust gases of the cabin and improve the local and overall ventilation environment.

Whether it is to enter the cabin by multi-arranging the fan or pulling the air duct, although the flow of gas in the cabin is increased, because the cabin is a limited space, the number of air inlets and air outlets is small and the area is small, and the compartments are crossed. More, the exhaust path is long, and the exhaust gas in the independent cabin is often unable to be effectively discharged out of the cabin. Even if it is discharged, the exhaust gas discharged from each compartment will be collected again and then rushed from one space to another inside the hull. Space can not be effectively discharged outside the hull, resulting in poor ventilation in the cabin. Whether it is the on-site operator or the inspection personnel entering the cabin and then coming out, it will become a "black-faced black face", affecting health and violating green shipbuilding.

The utility model has the beneficial effects that the fan connecting tooling and the fan cooperate, and is applied in the engine room and narrow After the exhaust gas is generated in the cabin, the bottom ballast tank, etc., it is not easy to discharge out of the cabin or it is difficult to form an effective ventilation path. The exhaust gas is easily collected, and the exhaust pipe is directly pulled into the above compartment by arranging the fan on the outer hull plate and the top deck. In the middle, the exhaust gas is directly taken out of the hull by the fan, and the exhaust gas entering the exhaust pipe is completely isolated from the space around the exhaust path, and does not cause secondary pollution of the space around the exhaust path, thereby fundamentally “eliminating” the exhaust gas in the cabin. Achieving the goal of improving the working environment is a truly effective and scientific method of pumping during shipbuilding.
