Exhaust pipe cabin-through structure for top of ship chimney

Abstract

The invention discloses an exhaust pipe cabin-through structure for the top of a ship chimney. The exhaust pipe cabin-through structure comprises a slantly arranged chimney top plate, an exhaust pipe which is arranged in the middle of the chimney top plate, a fixing and reinforcing enclosing plate which is fixed on the chimney top plate, a rain shielding enclosing plate which is arranged on the fixing and reinforcing enclosing plate and a plurality of locking mechanisms by which the exhaust pipe is supported and positioned on the fixing and reinforcing enclosing plate; the rain shielding enclosing plate is fixedly connected with the upper end of the exhaust pipe; the exhaust pipe is fixed on the fixing and reinforcing enclosing plate; and after penetrating through the fixing and reinforcing enclosing plate, the lower end of the exhaust pipe is fixedly connected with an exhaust pipeline of the ship chimney through a flange at the lower end of the exhaust pipe, and the rain shielding enclosing plate covers the upper side of the fixing and reinforcing enclosing plate. The exhaust pipe cabin-through structure is simple in structure; all components are connected stably and reliably; a heat transferring area is small; the temperature of the chimney top plate is not prone to raise, the anti-corrosive paint hardly falls off, and the service life of the chimney top plate is prolonged. The exhaust pipe has enough expansion and contraction deformation space, the manufacturing and installation errors are compensated, and the whole exhaust pipe can be installed in place.

Description

technical field [0001] The invention relates to a ship chimney, in particular to a positioning support structure for the top of a ship engine exhaust pipe to pass through a cabin, and belongs to the technical field of ship equipment. Background technique [0002] The exhaust gas generated by the ship's engine is finally discharged to the outside of the ship through the exhaust pipe and muffler connected to the engine. The top of the exhaust pipe passes through the top plate of the chimney and bends to exhaust. A reliable positioning support structure is required between the exhaust pipe and the top plate of the chimney, which can not only ensure that the connection between the exhaust pipe and the top plate of the chimney is stable and reliable, but also ensure that the exhaust pipe It has enough thermal expansion and contraction deformation space, and at the same time prevents rainwater from entering the cabin. The existing exhaust pipe adopts a fixed structure that is di...

AI Technical Summary

Problems solved by technology

The existing exhaust pipe adopts a fixed structure that is directly welded to the chimney roof, which easily causes the chimney roof to deform with the thermal expansion and contraction of the exhaust pipe, and the chimney roof is subject to great temperature stress. A large amount of heat is transferred to the chimney roof, causing the anti-corrosion paint on the chimney roof to be damaged and peeled off after being heated, resulting in corrosion of the chimney roof and shortening its service life
