[0032] The embodiment of the present application provides a ship, which relates to the technical field of water transportation vehicles. The ship includes a yacht, a fishing boat, a cargo ship, a passenger ship, etc., which is not specifically limited here.

[0033] like Figures 1 to 3 As shown, the ship 100 provided in this embodiment includes: a hull 110 and an exhaust assembly 120 .

[0034] The bottom 114 of the hull 110 is provided with a first exhaust port 111, and the tail 115 of the hull 110 is provided with a second exhaust port 112. The exhaust assembly 120 is arranged inside the hull 110, and the exhaust assembly 120 includes a main exhaust pipe 121 and a branch exhaust pipe 122, one end of the main exhaust pipe 121 is connected to the first exhaust port 111, and the other end of the main exhaust pipe 121 is connected to the engine arranged in the hull 110, one end of the branch exhaust pipe 122 is connected to the main exhaust pipe 121, and the other end of the branch exhaust pipe 122 is connected to the second exhaust port 112.

[0035] like Figure 2As shown, exemplarily, the hull 110 has a first side portion 116 and a second side portion 117 that are oppositely disposed in the width direction y thereof, and the exhaust assembly 120 is disposed close to the first side portion 116 or close to the second side portion 117 .

[0036] It should be mentioned that when a ship is sailing, it usually adopts an upward exhaust method, that is, the exhaust pipe connected to the engine extends upward from both sides of the hull 110 to the top of the hull, so as to discharge the exhaust gas of the engine into the air from bottom to top. However, the upward exhaust design will bring a lot of noise, affecting the user experience.

[0037] It can be understood that, in the ship 100 provided in this embodiment, since the bottom 114 of the hull 110 is provided with a first exhaust port 111, the tail 115 of the hull 110 is provided with a second exhaust port 112, one end of the main exhaust pipe 121 is connected to the first exhaust port 111, the other end of the main exhaust pipe 121 is connected to the engine arranged in the hull 110, one end of the branch exhaust pipe 122 is connected to the main exhaust pipe 121, and the other end of the branch exhaust pipe 122 is connected to the second exhaust port 112. In this way, when the ship 100 is sailing, the exhaust gas discharge pressure of the engine is relatively large, and the exhaust gas is mainly discharged underwater (i.e., below the water surface 200) from the first exhaust port 111 at the bottom 114 of the hull 110 through the main exhaust pipe 121, so as to use the seawater to provide a noise reduction effect, reduce the noise caused by the exhaust gas discharge, and provide a quieter and more comfortable boating environment for users. When the ship 100 is in standby mode, the exhaust gas discharge pressure of the engine is relatively low, and the exhaust gas is mainly discharged from the second exhaust port 112 at the rear portion 115 of the hull 110 to the surface of the water (ie, above the water surface 200) through the branch exhaust pipe 122 .

[0038] like Figure 1 As shown, in one embodiment, the bottom 114 of the hull 110 is provided with an arc-shaped recess 113 communicating with the first exhaust port 111 , and the arc-shaped recess 113 is located on one side of the first exhaust port 111 close to the tail 115 of the hull 110 .

[0039] Exemplarily, the arc-shaped recess 113 may be in a shell shape or an arc shape, which is not specifically limited herein.

[0040] In this embodiment, since the bottom 114 of the hull 110 is provided with an arc-shaped recess 113 connected to the first exhaust port 111, the arc-shaped recess 113 is located on the side of the first exhaust port 111 close to the tail 115 of the hull 110. In this way, the arc-shaped recess 113 can reduce the elevation angle of the ship 100 when sailing, and reduce the resistance caused by seawater flowing through the main exhaust pipe 121.

[0041] like Figure 2 and Figure 3As shown, in one embodiment, the exhaust assembly 120 further includes a flexible connecting pipe 123 , which is connected between the engine and an end of the main exhaust pipe 121 away from the first exhaust port 111 .

[0042] Exemplarily, the flexible connecting tube 123 is selected from a bellows, a hose, etc., and no specific limitation is made here. In addition, the bellows and the hose can be made of elastic materials such as rubber, silicone, etc.

[0043] In this embodiment, since the flexible connecting pipe 123 is connected between the engine and the end of the main exhaust pipe 121 away from the first exhaust port 111, a soft connection between the engine and the main exhaust pipe 121 is achieved, thereby avoiding the vibration caused by the engine operation being transmitted to the exhaust component 120 due to a hard connection.

[0044] like Figure 3 As shown, further, the inner diameter of the flexible connecting tube 123 is D 1 , the inner diameter of the main exhaust pipe 121 is D 2 , satisfying: 1<D 2 / D 1 ≤2.

[0045] For example, D 2 / D 1 Any value among 1.2, 1.3, 1.4, 1.45, 1.5, 1.55, 1.6, 1.7, 1.8, 1.9, 2 or any value in the range consisting of any two of them can be selected, and no specific limitation is made here.

[0046] In this embodiment, due to the inner diameter D of the main exhaust pipe 121 2 Greater than the inner diameter D of the flexible connecting tube 123 1 , but less than or equal to the inner diameter D of the flexible connecting pipe 123 1 In this way, the exhaust gas of the engine enters the main exhaust pipe 121 with a larger inner diameter from the flexible connecting pipe 123 with a smaller inner diameter, which can achieve a certain noise reduction effect.

[0047] like Figure 3 As shown, further, the inner diameter of the flexible connecting tube 123 is D 1 The inner diameter of the branch exhaust pipe 122 is D 3 , satisfying: 1 / 3≤D 3 / D 1 <1.

[0048] For example, D 3 / D 1 Any value among 1 / 3, 0.4, 0.5, 0.6, 0.65, 2 / 3, 0.68, 0.7, 0.8, 0.9 or any value in the range consisting of any two of them can be selected, and no specific limitation is made here.

[0049] In this embodiment, since the inner diameter D of the branch exhaust pipe 122 is 3 Smaller than the inner diameter D of the flexible connecting pipe 123 1 , but greater than or equal to the inner diameter D of the flexible connecting pipe 123 1 In this way, the possibility of exhaust gas from the branch exhaust pipe 122 to the water through the second exhaust port 112 when the ship 100 is not in the standby state can be reduced, so that most of the exhaust gas can be discharged underwater from the main exhaust pipe 121 through the first exhaust port 111.

[0050] It should be noted that D 2 / D 1 Preferably, it is 1.5, that is, the inner diameter of the main exhaust pipe 121 is 1.5 times the inner diameter of the flexible connecting pipe 123. 3 / D 1 It is preferably 2 / 3, that is, the inner diameter of the branch exhaust pipe 122 is 2 / 3 of the inner diameter of the flexible connecting pipe 123 .

[0051] like Figure 2 and Figure 3 As shown, in one embodiment, the exhaust assembly 120 further includes a first water guide pipe 124 , which is connected to one end of the main exhaust pipe 121 away from the first exhaust port 111 and is used to introduce seawater into the main exhaust pipe 121 .

[0052] In this embodiment, the first water diversion pipe 124 is connected to one end of the main exhaust pipe 121 away from the first exhaust port 111, and is used to introduce seawater into the main exhaust pipe 121. In this way, seawater is used as a heat exchange medium to reduce the exhaust gas discharge temperature. At the same time, during the exhaust gas discharge through the main exhaust pipe 121, the noise can be transmitted to the seawater introduced by the first water diversion pipe 124. The seawater in mid-air cannot transmit the noise better, and part of the noise of the exhaust gas can be consumed back and forth, thereby achieving a muffler effect similar to that of a muffler, and further reducing the noise caused by the exhaust gas discharge.

[0053] like Figure 3 As shown, further, the exhaust assembly 120 also includes a water spray pipe 125 , which is located inside the main exhaust pipe 121 and connected to the first water guide pipe 124 , and has a plurality of spray holes 1251 .

[0054] In this embodiment, the first water diversion pipe 124 is connected via the water spray pipe 125, so that seawater can be introduced into the main exhaust pipe 121 and the introduced seawater can contact the exhaust gas in the main exhaust pipe 121 in the form of a spray, thereby achieving better cooling and noise reduction effects.

[0055] like Figure 2 and Figure 3As shown, in one embodiment, the exhaust assembly 120 further includes a second water guide pipe 126 , which is connected to one end of the branch exhaust pipe 122 close to the main exhaust pipe 121 and is used to introduce seawater into the branch exhaust pipe 122 .

[0056] In this embodiment, since the second water diversion pipe 126 is connected to one end of the branch exhaust pipe 122 close to the main exhaust pipe 121, it is used to introduce seawater into the branch exhaust pipe 122. In this way, seawater is used as a heat exchange medium to reduce the exhaust gas discharge temperature. At the same time, during the exhaust gas discharge through the branch exhaust pipe 122, the noise can be transmitted to the seawater introduced by the second water diversion pipe 126. The seawater in the air cannot conduct the noise better, so that part of the noise of the exhaust gas can be consumed back and forth, thereby achieving a muffler effect similar to that of a muffler, and further reducing the noise caused by the exhaust gas discharge.

[0057] like Figure 2 and Figure 3 As shown, in one embodiment, the centerline of the main exhaust pipe 121 is perpendicular to the length direction x of the hull 110 , and the centerline of the branch exhaust pipe 122 is parallel to the length direction x of the hull 110 .

[0058] In this embodiment, since the center line of the main exhaust pipe 121 is perpendicular to the length direction x of the hull 110, the center line of the branch exhaust pipe 122 is parallel to the length direction x of the hull 110. In this way, the exhaust gas in the main exhaust pipe 121 can be discharged along a path approximately perpendicular to the water surface 200, and the exhaust gas in the branch exhaust pipe 122 can be discharged along a path approximately parallel to the water surface 200.

[0059] In summary, the ship 100 provided in this embodiment includes a hull 110 and an exhaust assembly 120. A first exhaust port 111 is provided at the bottom 114 of the hull 110, and a second exhaust port 112 is provided at the tail 115 of the hull 110. The exhaust assembly 120 is disposed inside the hull 110, and includes a main exhaust pipe 121, a branch exhaust pipe 122, a flexible connecting pipe 123, a first water diversion pipe 124, a second water diversion pipe 126, and a water spray pipe 125. One end of the main exhaust pipe 121 is connected to the first exhaust port 111, the flexible connecting pipe 123 is connected between the engine and the end of the main exhaust pipe 121 away from the first exhaust port 111, one end of the branch exhaust pipe 122 is connected to the main exhaust pipe 121, and the other end of the branch exhaust pipe 122 is connected to the second exhaust port 112, the first water guide pipe 124 is connected to the end of the main exhaust pipe 121 away from the first exhaust port 111, the water spray pipe 125 is located inside the main exhaust pipe 121 and connected to the first water guide pipe 124, and the water spray pipe 125 has a plurality of spray holes 1251, and the second water guide pipe 126 is connected to the end of the branch exhaust pipe 122 close to the main exhaust pipe 121, and is used to introduce seawater into the branch exhaust pipe 122. The bottom 114 of the hull 110 is provided with an arc-shaped recess 113 connected to the first exhaust port 111, and the arc-shaped recess 113 is located on the side of the first exhaust port 111 close to the tail 115 of the hull 110.

[0060] When the ship 100 is sailing, the exhaust gas emission pressure of the engine is relatively high, and the exhaust gas is mainly discharged underwater (i.e., below the water surface 200) from the first exhaust port 111 at the bottom 114 of the hull 110 through the main exhaust pipe 121, so as to utilize seawater to provide a noise reduction effect and reduce the noise caused by exhaust gas emission, thereby providing users with a quieter and more comfortable boating environment. At the same time, the seawater introduced by the first water pipe 124 is sprayed into the main exhaust pipe 121 through the spray hole 1251 of the water spray pipe 125, which can further achieve a noise reduction effect and reduce the temperature of the exhaust gas discharged from the main exhaust pipe 121. In addition, the arc-shaped recess 113 can reduce the elevation angle of the ship 100 when sailing and reduce the resistance caused by seawater flowing through the main exhaust pipe 121.

[0061] When the ship 100 is in standby mode, the exhaust gas emission pressure of the engine is relatively low, and the exhaust gas is mainly discharged from the second exhaust port 112 at the rear part 115 of the hull 110 to the water (i.e. above the water surface 200) through the branch exhaust pipe 122. At the same time, the seawater introduced by the second water pipe 126 can further achieve a noise reduction effect and reduce the temperature of the exhaust gas discharged from the branch exhaust pipe 122.
