Abstract
The utility model relates to a gauged orifice device for boats and ships are inspectd under water, including the gauged orifice base (1a) of rigid coupling on rudder blade planking (5), the gauged orifice base is hollow structure, and annular gland (1b) is installed on the top of gauged orifice base, inlay between the annular gland sum check hole bottom seat and establish the two dull and stereotyped transparent thing (1e) that link up each other of separation, the top rigid coupling of annular gland has apron (1d). Dull and stereotyped transparent thing is toughened glass or withstand voltage glass. The up end and rudder blade planking looks parallel and level of apron. Under water among the inspection process, the utility model discloses can effectively prevent the sea water to get into the watertight space, prolong hydraulic nut's life to avoid rudderstock and rudder to sell by the hidden danger of seawater corrosion, reduced cost of maintenance. Additionally, the utility model discloses the cost is lower, and convenient operation does benefit to and in industry popularizes and applies.
Description
Technical field
The utility model relates to the device for checking rudder stock and rudder pintle place hydraulic efficiency nut or plain nut whether to loosen, and specifically refers to, a kind of test hole device for boats and ships in-water survey.
Background technology
In current classification society rule, boats and ships in-water survey is attached great importance to, and be proposed specific requirement.With regard to rudder system, except the axle sleeve divided except axle pastern and sleeve clearances are checked, emphasis is needed to check rudder stock and rudder pintle place hydraulic efficiency nut or plain nut (hereinafter referred to as nut) whether to loosen.The common practice of this inspection is the inspection door by being arranged on rudder blade outside plate, observe the vertical bend pipe be arranged on nut, if this bend pipe is just to inspection door center, nut does not loosen not have displacement then can judge, otherwise judges the loosening situation of nut according to its misalignment.Because inspection door is positioned under water, prior art is used for the form that the inspection door of this inspection normally adopts waterproof plug, its inspection principle is shown in shown in Fig. 1 and Fig. 2, when carrying out in-water survey, the screwed out part of water drain cock special wrench set is screwed out, and then observe the displacement situation of check mark, the watertight space that seawater will inevitably be caused after this operation to enter Fig. 1 indicate, nut is caused to be in the hybird environment of seawater and air, this environment will speed up the corrosion of hydraulic efficiency nut or even rudder stock and rudder pintle, bring boats and ships to use hidden danger, and directly cause economic loss.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of test hole device for boats and ships in-water survey, and seawater can be avoided when carrying out in-water survey operation to enter watertight space.
The utility model solves the problem technical scheme is as follows:
For a test hole device for boats and ships in-water survey, comprise the test hole base be fixed on rudder blade outside plate, it is characterized in that:
Described test hole base is hollow structure, and the top of test hole base is provided with annular gland, and be embedded the dull and stereotyped transparency that both obstructs are mutually through between described annular gland and test hole base, the top of described annular gland is connected with cover plate.
As further improvement, in order to meet the Streamline Design requirement of rudder blade outside plate, the upper surface of described cover plate is mutually concordant with rudder blade outside plate.
Further, in order to strengthen leak tightness, between described dull and stereotyped transparency and annular gland and test hole base, packing seal is installed.
Preferably, be connected by screw between described gland and test hole base, described screw distributes along the annulus uniform intervals of gland.
Preferably, described cover plate is circular, and be connected by screw between cover plate and annular gland, described screw distributes along the periphery uniform intervals of cover plate.
Described dull and stereotyped transparency preferably adopts case hardened glass or withstand voltage glass.
In order to further facilitate observation, the material of described cover plate is transparent material.
Principle of work of the present utility model is, when in-water survey will be carried out, as long as the screw on cover plate is unloaded, namely observe check mark (bend pipe) by dull and stereotyped transparency and whether be shifted, because seawater is isolated from the outside by dull and stereotyped transparency, avoid seawater and enter in seal cavity.Both met the requirement of conventional subsea inspection, the water tightness of nut surrounding environment can have been ensured again.
Compared with prior art, the beneficial effects of the utility model are:
Under water in checkout procedure, the utility model effectively stops seawater to enter watertight space, extends the service life of hydraulic efficiency nut, and avoids rudder stock and rudder pintle by the hidden danger of marine corrosion, reduces maintenance cost.In addition, the utility model cost is lower, easy to operate, is beneficial to and in industry applies.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail; the restriction of described embodiment not to utility model protection scope; obviously; those of ordinary skill in the art are not needing to obtain other embodiments under the prerequisite paying creative work, and these all belong to protection domain of the present utility model.
Shown in composition graphs 3 and Fig. 4, a kind of test hole device for boats and ships in-water survey, comprise the test hole base 1a be fixed on rudder blade outside plate 5, described test hole base is hollow structure, the top of test hole base is provided with annular gland 1b, be embedded the dull and stereotyped transparency 1e that both obstructs are mutually through between described annular gland and test hole base, described dull and stereotyped transparency is preferably case hardened glass or withstand voltage glass.Between described dull and stereotyped transparency and annular gland and test hole base, packing seal 1f is installed.
The top of described annular gland is connected with cover plate 1d.Described cover plate also can adopt transparent material to make, and need not unload lower cover like this and just can carry out in-water survey observation.
In order to meet the Streamline Design requirement of rudder blade outside plate, the upper surface of described cover plate is mutually concordant with rudder blade outside plate.
Be connected by screw 1c between described gland with test hole base, described screw distributes along the annulus uniform intervals of gland.Described cover plate is circular, and be connected by screw 1c between cover plate with annular gland, described screw distributes along the periphery uniform intervals of cover plate.
Principle of work of the present utility model is, when in-water survey will be carried out, as long as the screw on cover plate is unloaded, namely whether be shifted by dull and stereotyped transparency sensing check mark (bend pipe), because seawater is isolated from the outside by dull and stereotyped transparency, avoid seawater and enter in seal cavity.Both met the requirement of conventional subsea inspection, the water tightness of nut surrounding environment can have been ensured again.
