[0002] A yacht refers to a ship with a mechanical propulsion power device that is only used by the yacht owner himself for activities such as sightseeing and leisure entertainment. In developed countries, yachts are mostly privately owned like cars. In developing countries, yachts are mostly used as business items in parks and tourist attractions for people to consume, and a small number are also used as working tools for port supervision, public security, and border defense. The essential feature that a yacht is an entertainment tool differentiates it from high-speed ships and tourist passenger ships that are used as transportation tools. Yachts will become the next generation of durable consumer goods to enter families just like cars.

[0003] In order to ensure the ventilation in the yacht engine room, an air inlet is provided in the engine room to allow external air to enter the engine room. However, due to the high humidity in the sea air and frequent rainy days, moisture and rainwater are easily introduced into the engine room through the air inlet, resulting in excessive humidity in the engine room, which in turn affects the comfort of people in the engine room and may even cause damage to the internal facilities of the engine room due to excessive moisture.

Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1 - 5 , a drainage prevention device for the air inlet of a yacht engine room, including an air inlet pipe 1. A connecting pipe 2 is installed at the bottom of the air inlet pipe 1, and a hose 4 is installed at the top of the air inlet pipe 1. The hose 4 is bent in an arc shape. During actual use, the air inlet pipe 1 is fixed on the outer wall of the yacht engine room, and the connecting pipe 2 is placed inside the engine room. Among them, at least one fan 3 is arranged inside the connecting pipe 2 to guide the air outside the engine room, so that the air can enter the engine room along the air inlet pipe 1 and the connecting pipe 2 from the hose 4.

[0025] As Figure 2 shown, a connecting seat 17 is installed along the edge of the other end of the hose 4. A frame 18 is installed at the bottom of the connecting seat 17. A dust filter 19 is arranged inside the frame 18 to remove dust from the air entering the hose 4, so as to prevent dust and other sundries from entering the engine room along with the air; As Figure 4 and Figure 5 shown, a desiccant box 20 is arranged at the top of the frame 18. Desiccant is arranged inside the desiccant box 20. A connecting frame 21 is arranged along the edge of the bottom of the desiccant box 20. The connecting frame 21 is fixed on the frame 18. When the air enters the hose 4 from the port of the hose 4, it will pass through the desiccant box 20, thereby adsorbing the water vapor in the air, drying the air, and preventing a large amount of water vapor from entering the engine room, thereby preventing the humidity in the engine room from being too high and affecting the comfort of the internal environment of the engine room.

[0026] Furthermore, the frame 18 is fixed on the connecting seat 17 through fasteners, and the connecting frame 21 is fixed on the frame 18 through fasteners. During actual use, the fasteners are one of bolts and screws, so as to facilitate the disassembly of the frame 18 on the connecting seat 17 and the disassembly of the desiccant box 20 on the frame 18, and facilitate the replacement of the dust filter 19 and the desiccant.

[0027] As Figure 1 and Figure 2As shown in the figure, fixed rods 6 are connected to both sides of the connecting seat 17 through support shafts 5. The other ends of the fixed rods 6 are installed on the rotating shaft 7. The rotating shaft 7 is coaxially arranged with the hose 4. Support frames 8 are installed at both ends of the rotating shaft 7. The other ends of the support frames 8 are fixed to the outer wall of the air inlet pipe 1 through fixed frames 9. Under the rotation of the rotating shaft 7, the connecting seat 17 can drive the hose 4 to be wound up, so that the hose 4 deflects with the rotating shaft 7 as the axis. In this way, on rainy days, the port of the hose 4 can be turned downward to prevent rainwater from falling into the hose 4. On sunny days, the port of the hose 4 can be turned to the horizontal direction, so that when the yacht is moving, the convective air can more easily enter the hose 4 and flow into the engine room.

[0028] As Figure 3 shown, a first sprocket 11 is coaxially installed at one end of the rotating shaft 7. A second sprocket 12 is arranged on the side of the first sprocket 11 close to the air inlet pipe 1. The second sprocket 12 is connected to the first sprocket 11 through a chain 13. The second sprocket 12 is coaxially installed on the drive motor 14. The drive motor 14 is arranged in the motor box 15. The motor box 15 is fixed on the support frame 8. The operation of the drive motor 14 provides power for the rotation of the rotating shaft 7.

[0029] Furthermore, in order to protect the sprockets and the chain 13, a protective cover 16 is arranged on one side of the support frame 8. The protective cover 16 is fixed to the support frame 8. Among them, the first sprocket 11, the second sprocket 12 and the chain 13 are all placed in the protective cover 16, so as to wrap the sprockets and the chain 13, thereby isolating the sprockets and the chain 13 from contact with the external environment.

[0030] It should be noted that, as Figure 2 shown, a reinforcing plate 10 is arranged between the support frame 8 and the fixed frame 9. One side of the reinforcing plate 10 is fixed to the support frame 8, and the other side of the reinforcing plate 10 is fixed to the fixed frame 9, which improves the support strength of the fixed frame 9 and the support frame 8.

[0031] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
