The invention discloses a ship ventilating duct structure with toughness and anti-seismic performance, relates to the technical field of ship ventilating ducts, and solves the problems that most of filter screens on air inlets at the head ends of existing ventilating duct structures need to be regularly and manually cleaned, and operation is tedious, strenuous and inconvenient. The ship ventilating duct structure with toughness and anti-seismic performance comprises a duct body and a mounting seat, a mounting ring is thickened, welded and fixed to an opening in the head end of the duct body, a circular filter screen is slidably plugged in the mounting ring, a lifting ring is downwards welded to the middle of the bottom of the mounting ring, the mounting seat comprises a six-edge positioning shaft and a six-edge rail rod, and the whole mounting seat is formed by jointly welding a front transverse supporting plate, a rear transverse supporting plate and three middle axial supporting plates at equal intervals. The sliding driving force of the circular filter screen comes from the bumping impact force of the duct body, a cleaning motor additionally matched with the circular filter screen is omitted, and the manufacturing cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of ship ventilation ducts, in particular to a ship ventilation duct structure with toughness and anti-seismic performance. Background technique [0002] Ships are an important means of water transportation. With the development of science and technology, the development of ships has undergone great changes. Ships have evolved from wooden boats to steamboats, and then to today's fully electronically controlled thousand-ton ships. Most of the existing ship ventilation ducts are located inside the hull, and the ventilation inside the hull is poor. In order to increase the ventilation effect inside the ship, ventilation ducts that communicate with the outside world are usually installed in the ship. However, due to the special environment on the ship, ventilation is required Pipes are earthquake resistant. [0003] For example, the patent No. CN201620054748.4 discloses a ship ventilation duct structure. The ven...
