Description
Technical field
The present invention relates to ship machinery manufacturing technology field, specifically it is a kind of it is simple in construction, prevent into water, gas permeability
The good hull with fuel oil tank Ventilated cap protection device of energy.
Background technology
It is well known that the thermic load degree more and more higher of modern ships main frame, in order to ensure the optimum operation of marine main engine
State, ensure the most preferably ventilative state of fuel oil tank, the ventilative of fuel oil tank is that each ship must solve the problems, such as, typically in ship
Fuel oil permeability cell is all connected on the fuel oil tank of body, then permeability cell typically all stretches out the top of deck in ship structure and is provided with Ventilated cap,
But existing Ventilated cap is typically all to cover in the top of permeability cell, but during hull travels, sea beat can incite somebody to action
Seawater is rushed in permeability cell along Ventilated cap, existing Ventilated cap can not complete water proof, and general permeability cell is along
It is connected after being bent in hull with fuel oil tank, there is also defect for gas permeability.
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, there is provided one kind is simple in construction, prevents into water, gas permeability
The good hull with fuel oil tank Ventilated cap protection device of energy.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of hull with fuel oil tank Ventilated cap protection device, provided with hull, fuel oil tank is provided with hull, fuel oil tank is provided with
Air-vent, air-vent are provided with permeability cell, and the lower end of permeability cell is connected with air-vent, and deck in ship structure is stretched out in the upper end of permeability cell
And it is provided with Ventilated cap, it is characterised in that the inner side of described Ventilated cap is provided with backplate, and ventilative chamber is formed between backplate and Ventilated cap,
The middle part of described backplate is provided with connecting hole, and the upper end of described permeability cell is connected with the connecting hole on backplate, described company
The backplate for connecing hole periphery is provided with venthole, and the permeability cell set below described Ventilated cap is equipped with extractor fan, extractor fan
It is connected on permeability cell, is extracted out the gas in permeability cell by rotating extractor fan, while can also obstruct and rush to first through bearing holder (housing, cover)
Seawater is thrown away Ventilated cap by the seawater of plate.
Extractor fan top half of the present invention puts in the lower section of Ventilated cap, and the latter half of extractor fan is stretched out thoroughly
Gas cap, can not only obstruct extraneous seawater can also exhausting, increase the permeability of permeability cell.
The present invention forms ventilative chamber because the inner side of described Ventilated cap is provided with backplate, between backplate and Ventilated cap, described
The middle part of backplate be provided with connecting hole, the upper end of described permeability cell is connected with the connecting hole on backplate, described connecting hole
The backplate on periphery is provided with venthole, and the permeability cell set below described Ventilated cap is equipped with extractor fan, extractor fan warp beam
Bearing sleeve is connected on permeability cell, is extracted out the gas in permeability cell by rotating extractor fan, while can also obstruct and rush to deck
Seawater is thrown away Ventilated cap by seawater, and described extractor fan top half puts in the lower section of Ventilated cap, the lower half of extractor fan
Point stretch out Ventilated cap, can not only obstruct extraneous seawater can also exhausting, increase the permeability of permeability cell, have simple in construction, anti-
Only water inlet, the advantages that permeability is good.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
