Detailed Description

The present invention will be more clearly and completely described below by way of examples and with reference to the accompanying drawings, but the present invention is not limited thereto.

Like parts in the various embodiments are indicated with like reference numerals.

Example 1

As shown in fig. 1 to 3, a rudder blade inspection window according to an embodiment of the present invention includes a window seat 1, a window cover 2, a fixing member 3, and a rotating member 4, wherein the window seat 1 is disposed on a rudder blade 99 and has an inspection opening. The window cover 2 covers the inspection opening to seal the inspection opening, and the inspection opening can be opened at the same time. The fixing piece 3 is detachably connected to the window seat 1 and the window cover 2, when the window cover 2 is closed, the fixing piece 3 fixes the window seat 1 and the window cover 2, and when the window cover 2 is to be opened, the fixing piece 3 is detached. One end of the rotating member 4 is movably connected to the rudder blade 99, and the other end is connected to the window cover 2. The window cover 2 is opened and closed by the rotation of the rotary 4. Through this structure, the testing personnel can open window lid 2 on water and directly observe the inside condition of rudder blade through the visual observation of inspection door, observe whether hydraulic nut has not hard up, whether have the infiltration condition etc. rotating member 4 designs and also can make things convenient for testing personnel switch window lid 2.

The rotating member 4 comprises a base 42 and a bracket 41, the base 42 is movably connected to the rudder blade 99, the bracket 41 is connected to the base 42 and connected to the window cover 2, the base 42 comprises a bearing 422, which is directly connected to the base 42 and connected to the bearing 422, and can directly rotate around the base 42, and thereby the window cover 2 is driven to rotate to realize opening and closing. With this structure, the window cover 2 does not fall off when the window cover 2 is opened, but is rotated to open with the base 42 as the center of the circle, which further facilitates the opening and closing of the window cover 2 by the inspector.

The support 41 is provided with an avoiding groove 43, the avoiding groove 43 is inwards recessed along the direction far away from the rudder blade plate 99, when the detection personnel open the window cover 2, as shown in the figure, the rotating piece 4 is close to the window seat 1, one end of the window seat 1 extends into the avoiding groove 43 and accordingly the opening angle of the window cover 2 is enlarged, and the detection personnel can conveniently carry out the inside detection work of the rudder blade.

The fixing member 3 includes a plurality of bolts 31, a plurality of first through holes 32 are formed in the window base 1, a plurality of second through holes 33 are formed in the window cover 2, the plurality of first through holes 32 and the plurality of second through holes 33 are arranged oppositely, and the plurality of bolts 31 pass through the plurality of first through holes 32 and the plurality of second through holes 33 respectively to fix the window cover 2 on the window base 1. Through the structure, the window cover 2 and the window seat 1 can be connected more stably, and meanwhile, the bolt 31 is convenient to detach and can be used for opening the window cover 2.

The rudder blade inspection window further comprises a sealing ring 5, the sealing ring 5 is arranged between the window cover 2 and the window base 1 in a pressing mode, and the sealing ring 5 surrounds the inspection opening. Through setting up sealing washer 5, can guarantee the inside leakproofness of rudder blade, ensure not to cause the infiltration condition because of the joint gap between window lid 2 and the window seat 1.

The sealing ring 5 is a rubber gasket, so that the cost is reduced while the waterproof requirement is realized.

The observation hole 6 comprises a through hole 61, tempered glass 62 and a sealing element 63, the through hole 61 is opened on the window cover 2, the sealing element 63 covers the through hole 61, in the embodiment, a cavity is arranged between the sealing element 63 and the through hole 61, the tempered glass 62 is clamped in the cavity, the inner condition of the rudder blade can be directly observed by the tempered glass 62, meanwhile, the sealing element 63 strengthens the waterproofness of the whole observation hole 6, and a worker can observe the inner part of the rudder blade through the observation hole 6 underwater.

The window seat 1 and the rudder blade plate 99 are connected by welding, so that the whole inspection window is more stable.

Example 2

As shown in fig. 4 to 6, the same parts of the rudder blade inspection window structure of the present embodiment as those of embodiment 1 will not be repeated, and only the differences will be described. In this embodiment, a sliding slot 421 is further disposed on the base 42, and a bearing 422 is disposed in the sliding slot 421, wherein the bearing 422 is connected to the bracket 41 and can move in the sliding slot 421 to approach and separate from the rudder blade plate 99. This design allows the bearing 422 to slide in the sliding slot 421, which drives the bracket 41 and the window cover 2 connected to the bracket 41, when the bearing 422 is close to the rudder blade 99, the window cover 2 is outward away from the rudder blade 99, and at this time, the angle of rotation of the window cover 2 is larger, so that the angle at which the window cover 2 can be opened is also increased.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
