Problems solved by technology
If the nut is loose, it will have a great impact on the rudder system of the ship, thus affecting the safe navigation of the ship
Because the rudder blade has been submerged underwater for a long time, the condition of the internal nut cannot be observed after the traditional rudder blade is sealed, and it is impossible to judge whether the nut has loosened

Embodiment Construction
[0010] Such as figure 1 , 2 As shown, a rudder blade sealing plate observation device is composed of welding seat plate 1 and organic glass 2. The side that rubber washer 3 organic glass 2 is placed around is provided with external thread ring 4, and described sealing plate 5 is provided with observation hole, and round steel 5 is fixed on observation hole by nut 7.
[0011] The outside of the round steel 5 is coated with fluorescent paint.
[0012] The principle is as follows:
[0013] Weld the round steel 5 on the position where the nut 7 is facing the observation hole before the sealing plate 6, paint the fluorescent paint on the round steel 5, and install the rubber gasket 3, the plexiglass 2 and the external thread ring 4 in sequence on the welding In the seat plate 1, the welding seat plate 1 is welded on the sealing plate 6, and finally the sealing plate 6 is welded on the rudder blade.

The invention discloses an observation device of a rudder-blade sealing plate. The observation device consists of a welding seat plate and organic glass, wherein the welding seat plate is arranged on a sealing plate; the organic glass is arranged in the middle of the welding seat plate; a rubber washer is arranged at the periphery of the organic glass; an external thread ring is arranged on one side of the organic glass; an observation hole is formed in the sealing plate; a round steel bar is fixed at the observation hole through a nut. The observation device has the benefits that the observation device is simple to manufacture and mount, is low in cost, does not need to be maintained, is good in airtightness, is durable, can be used for underwater observation, is convenient to operate, and can be manufactured in batches and applied to various ships.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a rudder blade sealing plate observation device. Background technique [0002] The rudder blade is the body that produces the rudder force and is made of wood or steel. Now, except for wooden sailboats, they are all made of steel, and most of them are welded into hollow airfoils. The panel of the rudder blade is called the rudder plate (cover plate), and the rudder blade of the flat rudder (balanced rudder) is also the rudder plate. [0003] The rudder blade is an important part of the ship's rudder system, and it is connected with rudder stock, rudder pin, nut, etc. If the nut is loose, it will have a great impact on the rudder system of the ship, thus affecting the safe navigation of the ship. Because the rudder blade has been submerged underwater for a long time, it is impossible to observe the condition of the internal nut after the traditional rudder blade is...
