[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0032] Example 1

[0033] Please refer to Figures 1-8 As shown, a corrosion-resistant outboard exhaust pipe for ships includes a pipe body 1, an access end 101 is provided on the right side of the pipe body 1, a connecting end 102 adapted to the access end 101 is provided on the left side of the pipe body 1, a plurality of groups of fixing grooves 103 are opened on the outside of the access end 101, and a connecting mechanism 2 is installed on the outside of the connecting end 102. The connecting mechanism 2 includes a rotating ring 201, which is rotatably connected to the outside of the connecting end 102, and a plurality of groups of positioning columns 204 adapted to the fixing grooves 103 are slidably connected to the inside of the rotating ring 201. One end of the positioning column 204 passes through the connecting end 102 and extends to the inside of the connecting end 102. A gear ring 203 is fixedly connected to the outside of the rotating ring 201, and a driving module 3 is installed on the outside of the connecting end 102. The driving module 3 includes a driving gear 303, which meshes with the gear ring 203.

[0034] In this solution, the installation is completed by connecting two sets of the present invention end to end. The connecting end 102 of one set of the present invention is sleeved on the outside of the access end 101 of the other set of the present invention. The driving gear 303 can drive the gear ring 203 to rotate the rotating ring 201 on the outside of the connecting end 102, thereby squeezing the positioning post 204, so that the positioning post 204 moves to the inside of the connecting end 102 and is inserted into the inside of the fixing groove 103, thereby fixing the two sets of tube bodies 1.

[0035] It is understood by those skilled in the art that the inner sides of the pipe body 1 , the access end 101 and the connection end 102 are all welded with corrosion-resistant alloy linings, which can effectively resist corrosion of the pipe body 1 , the access end 101 and the connection end 102 by acidic washing water.

[0036] Example 2

[0037] Please refer to Figure 3-Figure 6As shown, a limiting groove 207 corresponding to the positioning post 204 is opened on the outer side of the rotating ring 201 , and the positioning post 204 is slidably connected to the inside of the limiting groove 207 .

[0038] The other end of the positioning post 204 is fixedly connected to an inclined block 208 . The upper surface of the inclined block 208 abuts against the inner wall of the limiting groove 207 . The cross-section of the inclined block 208 is wedge-shaped.

[0039] A fixing box 202 corresponding to the limiting groove 207 is fixedly connected to the outer side of the rotating ring 201 , and a magnet 209 is fixedly connected to the upper end of the fixing box 202 .

[0040] A limit ring 206 is fixedly connected to the inner side of the rotating ring 201 . A guide rail 205 adapted to the limit ring 206 is provided on the outer side of the connecting end 102 . The limit ring 206 is slidably connected to the inside of the guide rail 205 .

[0041] In this embodiment, the rotating ring 201 can drive the limiting groove 207 to rotate, thereby causing the inner wall of the limiting groove 207 to squeeze the upper surface of the inclined block 208, thereby driving the inclined block 208 to move inwardly of the connecting end 102 and driving the positioning column 204 to move;

[0042] Furthermore, when the tube body 1 needs to be maintained or replaced, the rotating ring 201 is rotated in the reverse direction to reset, thereby attracting the inclined block 208 through the magnet 209, causing it to move to the inside of the fixing box 202, thereby driving the positioning column 204 to move from the inside of the fixing groove 103 to the outside, thereby releasing the fixation between the two sets of tube bodies 1 and enabling quick installation and removal;

[0043] Furthermore, the initial state of the inclined block 208 is located inside the fixed box 202, and the upper surface of the inclined block 208 abuts against the inner wall of the limiting groove 207;

[0044] It is understood by those skilled in the art that the inclined block 208 is made of iron and can be attracted by the magnet 209 .

[0045] Example 3

[0046] Please refer to Figure 7-Figure 8 As shown, the driving module 3 further includes a mounting shell 301 , the interior of the mounting shell 301 is rotatably connected to a rotating shaft 302 , and a driving gear 303 is fixedly connected to the outer side of the rotating shaft 302 .

[0047] One end of the rotating shaft 302 extends to the outside of the mounting shell 301 and is fixedly connected to a connecting gear 307 .

[0048] The outer side of the connecting gear 307 is slidably connected to the rotating sleeve 305 .

[0049] A tooth groove 306 is formed on the inner side of the rotating sleeve 305 and meshes with the connecting gear 307 .

[0050] A positioning gear 304 is fixedly connected to the outer side of the mounting shell 301 , and the positioning gear 304 is engaged with the tooth groove 306 .

[0051] In this solution, the tooth groove 306 is engaged with the connecting gear 307, so that the rotating sleeve 305 can drive the connecting gear 307 to rotate, thereby driving the rotating shaft 302 and the driving gear 303 to rotate. After the two sets of tube bodies 1 are fixedly connected, the rotating sleeve 305 is slid to make the tooth groove 306 mesh with the positioning gear 304, thereby fixing the rotating sleeve 305, and then fixing the rotating shaft 302 and the connecting gear 307, preventing the connecting gear 307 from rotating and affecting the connection effect between the tube bodies 1.

[0052] Furthermore, the sliding rotation sleeve 305 disengages the tooth groove 306 from the positioning gear 304 , thereby resuming the rotation of the rotation sleeve 305 .

[0053] The working principle and usage process of the present invention are as follows: First, two sets of the present invention are connected end to end, and the connecting end 102 of one set of the present invention is sleeved on the outside of the access end 101 of the other set of the present invention. Then, the connecting gear 307 is driven to rotate by the rotating sleeve 305, and then the rotating shaft 302 and the driving gear 303 are driven to rotate, thereby driving the gear ring 203 to make the rotating ring 201 rotate on the outside of the connecting end 102 and squeeze the upper surface of the inclined block 208, thereby driving the inclined block 208 to move toward the inside of the connecting end 102, so that the positioning column 204 moves and is inserted into the inside of the fixing groove 103, thereby fixing the two sets of tube bodies 1. After that, the rotating sleeve 305 is slid and the tooth groove 306 is engaged with the positioning gear 304, thereby fixing the rotating sleeve 305, and then fixing the rotating shaft 302 and the connecting gear 307 to prevent the connecting gear 307 from rotating and affecting the connection effect between the tube bodies 1. When the tube body 1 is maintained or replaced, the rotating ring 201 is rotated in the opposite direction to reset, and the inclined block 208 is attracted by the magnet 209 to move it to the inside of the fixed box 202, thereby driving the positioning column 204 to move from the inside of the fixing groove 103 to the outside, releasing the fixation between the two groups of tube bodies 1, and thus the tube body 1 is disassembled.

[0054] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention.
