DETAILED DESCRIPTION

[0022] Embodiment 1:

[0023] The following is a further detailed description of the technical solution of the utility model in conjunction with the drawings and specific embodiments of the specification. A ship air duct provided in the present application includes an air duct side panel 1; an air duct bottom plate 2 is installed at the bottom of the air duct side panel 1, a plug welding hole 201 is provided at the bottom of the air duct bottom plate 2, a plug welding flat steel 3 is installed at the inner top of the air duct bottom plate 2, a through groove 4 is provided on one side of the bottom of the air duct bottom plate 2, an angle steel 5 is installed at the top of the air duct bottom plate 2 near the through groove 4, and a positioning mechanism 6 is installed on the inner wall of the air duct side panel 1.

[0024] Specifically, as attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the bottom of the duct side plate 1 is connected to the duct bottom plate 2 by welding, part of the ordinary ribs of the duct bottom plate 2 are disconnected to form a through groove 4, the duct bottom plate 2 is provided with a plug welding hole 201, the duct bottom plate 2 is provided with a plug welding flat steel 3 at the strong structural ribs, an angle steel 5 is added inside the duct side plate 1, and the duct bottom plate 2 is welded to the angle steel 5, thereby improving the strength of the duct side plate 1 and the duct bottom plate 2, and thus will not affect the structural strength of the hull.

[0025] Furthermore, the positioning mechanism 6 includes an insertion rod 601 and a positioning block 602 . The insertion rods 601 are installed at the four corners of the top of the air duct bottom plate 2 , and the positioning block 602 is installed on one side of the inner wall of the air duct side plate 1 close to the insertion rod 601 .

[0026] Specifically, as attached Figure 3 As shown, in order to achieve positioning when welding the air duct side panel 1 and the air duct bottom panel 2, the plug rod 601 is fixedly installed on the top of the air duct bottom panel 2 by bolts. By moving the air duct bottom panel 2, the plug rod 601 on the top of the air duct bottom panel 2 is inserted into the interior of the positioning block 602, and then the air duct side panel 1 and the air duct bottom panel 2 can be positioned, which is convenient for workers to weld the air duct side panel 1 and the air duct bottom panel 2 later.

[0027] Furthermore, limit blocks 702 are installed on both sides of the insertion rod 601 , and a spring 701 is installed on one side of the limit block 702 close to the insertion rod 601 .

[0028] Specifically, as attached Figure 4 and attached Figure 5 As shown, in order to achieve the fixation between the duct side panel 1 and the duct bottom plate 2, the inside of the plug rod 601 is connected to the limit block 702 through the spring 701. The side of the limit block 702 close to the plug rod 601 is a flat surface, and the side away from the plug rod 601 is an inclined surface. When the plug rod 601 moves upward, the inner wall of the positioning block 602 will squeeze the inclined surface of the limit block 702. At this time, the spring 701 will be compressed. When the limit block 702 moves upward until it moves out of the inside of the positioning block 602, the limit block 702 will move out under the action of the spring 701. When the two groups of limit blocks 702 move outward and are located at the top of the positioning block 602, the fixation between the duct side panel 1 and the duct bottom plate 2 can be achieved.

[0029] Furthermore, a groove 7 is provided inside the insertion rod 601 close to the spring 701 , and the spring 701 is arranged inside the groove 7 .

[0030] Specifically, as attached Figure 5 As shown, in order to realize the movement of the spring 701 and the limit block 702, two groups of springs 701 are arranged inside the groove 7. When the spring 701 is deformed and the limit block 702 moves, it will move inside the groove 7, and the longest movement length of the spring 701 does not exceed the inner diameter of the groove 7, which can prevent the limit block 702 from being completely moved out from the inside of the limit block 702.

[0031] Furthermore, an L-shaped support plate 801 is installed at the corner position of the top inside the air duct side plate 1 , and the top end of the insertion rod 601 is located inside the L-shaped support plate 801 .

[0032] Specifically, as attached Figure 4 As shown, in order to improve the strength between the air duct side panel 1 and the air duct bottom panel 2, when the insertion rod 601 moves upward, the top end of the insertion rod 601 will be located inside the L-shaped support plate 801, and the corner position of the top air duct side panel 1 can be supported by the insertion rod 601 and the L-shaped support plate 801, thereby improving the strength between the air duct side panel 1 and the air duct bottom panel 2.

[0033] Furthermore, a connecting rod 8 is installed on the top of the positioning block 602 , and an L-shaped supporting plate 801 is connected to the top of the connecting rod 8 .

[0034] Specifically, as attached Figure 4 As shown, in order to achieve the connection between the positioning block 602 and the L-shaped support plate 801, the top of the positioning block 602 is connected to the L-shaped support plate 801 through a connecting rod 8, and the top L-shaped support plate 801 can be supported and fixed by the connecting rod 8.

[0035] Furthermore, reinforcing rods 9 are installed between the positioning blocks 602 .

[0036] Specifically, as attached Figure 4 As shown, in order to strengthen the strength of the air duct side plate 1, a reinforcing rod 9 is welded between the two groups of positioning blocks 602. The reinforcing rod 9 can improve the stability between the two groups of positioning blocks 602, thereby improving the strength of the positioning blocks 602.

[0037] Furthermore, a sound-absorbing layer 10 is installed on the inner wall of the air duct side plate 1 and the top of the air duct bottom plate 2 .

[0038] Specifically, as attached Figure 1 , Attachment Figure 3 and attached Figure 4 As shown, in order to reduce the noise of gas flow between the air duct side plate 1 and the air duct bottom plate 2, a sound-absorbing layer 10 is arranged on the inner wall of the air duct side plate 1 and the top of the air duct bottom plate 2, and is composed of a sound-absorbing material, which can reduce the noise of gas flow between the air duct side plate 1 and the air duct bottom plate 2.

[0039] Working principle: By moving the air duct bottom plate 2, the insertion rod 601 on the top of the air duct bottom plate 2 is inserted into the interior of the positioning block 602, and then the inner wall of the positioning block 602 will squeeze the inclined surface of the limit block 702. At this time, the spring 701 will be compressed. When the limit block 702 moves upward until it moves out of the interior of the positioning block 602, the limit block 702 will move out under the action of the spring 701. When the two sets of limit blocks 702 move outward and are located at the top of the positioning block 602, the air duct side plate 1 and the air duct can be closed. The top of the plug rod 601 will be located inside the L-shaped support plate 801, and the top of the air duct side plate 1 can be supported at the corner position by the plug rod 601 and the L-shaped support plate 801. Then the worker welds the air duct side plate 1 and the air duct bottom plate 2, adds plug welding flat steel 3 to the strong structural ribs of the air duct bottom plate 2, adds angle steel 5 inside the air duct side plate 1, and welds the air duct bottom plate 2 to the angle steel 5, which can improve the strength of the air duct side plate 1 and the air duct bottom plate 2.

[0040] As described above, the utility model cooperates with the duct side plates, duct bottom plates, plug welding holes, plug welding flat steels and angle steels for use. The ordinary ribs of the duct bottom plates are disconnected to form through grooves, and angle steels are added inside the duct side plates. The duct bottom plates are welded with the angle steels, so that the strength of the duct side plates and the duct bottom plates can be improved. The plug welding holes are opened in the duct bottom plates, and the plug welding flat steels are added to the strong structural ribs of the duct bottom plates, so that the strength thereof can be improved, and thus the structural strength of the hull will not be affected.

It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
