Description

View plug under a kind of marine water
Technical field
the utility model belongs to apparel technical field, relates to view plug, particularly a kind of underwater observation plug for boats and ships in-water survey under marine water.
Background technology
the boats and ships of current construction much have the requirement of in-water survey, so-called in-water survey refers to that classification society agrees to use in-water survey to replace a half time survey and dock inspection.The condition of in-water survey is less than 15 years the age of a ship, that half time survey in twice special survey being the cycle with 5 years.The content of inspection is mainly: the content such as structure, stern tube shaft, rudder system, screw propeller of ship hull plate, suction box, ship stern.Current in-water survey is dived into the water by diver to carry out hand inspection to every inspection item of boats and ships.
in above-mentioned inspection some inspection area be in not easily or can not be observed position, as checked rudder stock in rudder system in-water survey project, that whether fixing between rudder pintle and rudder blade has is loosening.Between rudder stock and rudder blade be to be close to cast steel body on rudder blade by the effect of hydraulic efficiency nut by the circular conical surface of rudder stock circular conical surface on and ensure between the two without relative motion, rudder pintle fixing similar with rudder stock, so checking whether rudder stock and rudder pintle have loosening is exactly mainly that to see whether hydraulic efficiency nut has loosening.But the hydraulic efficiency nut of above-mentioned rudder stock and rudder blade is all sealed in rudder blade inside, can not see outside rudder blade, and when checking under water, rudder blade is in below the water surface, so it is loosening very difficult to check whether hydraulic efficiency nut has.
Summary of the invention
the purpose of this utility model there are the problems referred to above for existing technology, proposes view plug under a kind of marine water.The advantages such as this view plug has easy to operate, safe and reliable, with low cost.
the purpose of this utility model realizes by following technical proposal: view plug under a kind of marine water, comprises the tubulose obturating plug of hollow, and on the inwall of described obturating plug, sealing is provided with glass, and described obturating plug also seals towards one end of seawater and is provided with gag.
by arranging glass at obturating plug inner wall sealing, such people just can see the situation of cabin interior residing for view plug from the outside of view plug.One end sealing of obturating plug is provided with gag, during installation, gag is arranged on by seawater side, can ensure that boats and ships are avoided causing damage to glass or destroying in navigation process like this, and the hydraulic pressure when boats and ships absorb water deeply can be avoided to damage glass by pressure.As long as open gag during inspection under water and just can see the situation of cabin interior residing for view plug by light source, easy to operate, safe and reliable, with low cost.
under above-mentioned a kind of marine water in view plug, on the inwall of described obturating plug, sealing is provided with columned plug body, and described plug body is hollow tubular structure, and described glass capsulation is arranged on the inwall of plug body.
on the inwall of obturating plug, sealing arranges plug body, and sealing arranges glass on the inwall of plug body, obturating plug can be made like this to weld on rudder blade well, then plug body is screwed in the inwall of obturating plug, thus can prevent when welding obturating plug because the rising of obturating plug temperature destroys glass by actv..
under above-mentioned a kind of marine water in view plug, described gag comprises operating portion, columned fixed part five, columned lid, the cross-sectional diameter of described lid is greater than the cross-sectional diameter of fixed part five, described operating portion and fixed part five are separately positioned on the both sides of lid, the junction of fixed part five and lid is provided with seal groove two, be provided with O RunddichtringO in described seal groove two, the outer wall of described fixed part five be provided with outside thread and be fixed on the inwall of obturating plug.
can conveniently open or closed gag in gag setting operation portion.
under above-mentioned a kind of marine water in view plug, described glass is also provided with two mutual vertically disposed scales.
glass is arranged scale can judge rudder stock intuitively, whether have between rudder pintle and rudder blade loosening.
under above-mentioned a kind of marine water in view plug, described operating portion is interior hexagonal structure or outer-hexagonal structure.
for on complete hermetic casing, this view plug is installed, because box house does not have light, so at least install two these view plugs, one for observe, another one import light.
the advantages such as compared with prior art, the utility model has: easy to operate, safe and reliable, with low cost
