DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4A ship steering exhaust emission structure includes a vertical discharge pipe 1, a transverse discharge pipe 2, a first elbow pipe 3 and a second elbow pipe 4. The vertical discharge pipe 1 is connected to the middle of the bottom end of the transverse discharge pipe 2. A first sealing plate 5 is arranged on one end of the transverse discharge pipe 2. A servo motor 6 is arranged on the outer side of the first sealing plate 5. A screw 7 is connected to the output end of the servo motor 6. The screw 7 is located in the transverse discharge pipe 2. A first plug 8 is threadedly connected to the screw 7. The first plug 8 is slidably adapted in the transverse discharge pipe 2 near the first plug 8. The first sealing plate 5 is located at the position of the first elbow pipe 3 connected to the top end of the horizontal discharge pipe 2, and the connection is located between the vertical discharge pipe 1 and the first sealing plate 5. A second sealing plate 9 is arranged on the other end of the horizontal discharge pipe 2. A second plug 10 is threadedly connected to the screw 7. The second plug 10 is slidably fitted in the horizontal discharge pipe 2 near the second sealing plate 9. The second elbow pipe 4 is connected to the top end of the horizontal discharge pipe 2 in the opposite direction to the first elbow pipe 3, and the connection is located between the vertical discharge pipe 1 and the second sealing plate 9.

[0021] The servo motor 6 controls the rotation of the screw 7 so that the first plug 8 and the second plug 10 can move synchronously in the same direction, thereby separately sealing the connection parts between the first elbow pipe 3 and the second elbow pipe 4 and the transverse discharge pipe 2, and through the different elbow directions between the first elbow pipe 3 and the second elbow pipe 4, the exhaust gas discharge is diverted, thereby effectively preventing rainwater from entering the interior of the ship through the discharge pipe when sailing in rainy days.

[0022] Specifically, in this embodiment, a protective cover 11 is provided on the outer side of the first sealing plate 5 , and the servo motor 6 is located inside the protective cover 11 . The protective cover 11 protects the servo motor 6 to prevent water from entering and causing a short circuit.

[0023] Specifically, in this embodiment, a baffle 12 is provided on the end of the screw 7 away from the servo motor 6. The baffle 12 is larger than the outer diameter of the screw 7 and is located on the outer side of the second sealing plate 9. The baffle 12 effectively limits the axial movement of the screw 7 and ensures the stability of the screw 7 when rotating.

[0024] Specifically, in this embodiment, threaded holes 13 of the same direction and specification are provided in the first block 8 and the second block 10, and the screw rod 7 is threadedly connected in the threaded hole 13. The same threaded hole 13 enables the rotation of the screw rod 7 to realize the synchronous and same-direction movement of the first block 8 and the second block 10.

[0025] Specifically, in the present embodiment, horizontal limit grooves 14 are provided on the inner walls on both sides of the transverse discharge pipe 2, and limit rods 15 are provided on the outer walls on both sides of the first block 8 and the second block 10. The limit rods 15 are slidably fitted in the limit grooves 14. The cooperation between the limit grooves 14 and the limit rods 15 enables the first block 8 and the second block 10 to perform stable horizontal movement.

[0026] Specifically, in the present embodiment, the lengths of the first plug 8 and the second plug 10 are the same, and both are larger than the inner diameters of the first elbow tube 3 and the second elbow tube 4. The center distance between the first plug 8 and the second plug 10 is the same as the center distance between the first elbow tube 3 and the second elbow tube 4, thereby ensuring the synchronous movement of the first plug 8 and the second plug 10 and smoothly realizing the alternating discharge of the first elbow tube 3 and the second elbow tube 4.

[0027] Specifically, in this embodiment, the ends of the first elbow pipe 3 and the second elbow pipe 4 are both provided with a plurality of leaf plates 16 that are vertically inclined and distributed downward. The leaf plates 16 ensure exhaust gas discharge while preventing rainwater and seabirds from entering.

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
