Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The components of this application, including the housing 1, positioning ring 2, positioning sleeve 3, rotating block 4, barrier mesh plate 5, positioning cylinder 6, limiting slide groove 7, limiting locking block 8, rotating motor 9, fixing frame 10, rotating blade 11, I-shaped barrier sleeve 12, air guide hole 13, filter mesh plate 14, and limiting ring 15, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0020] Please see Figure 1-3 A ventilation device for ships includes a housing 1 and a limiting groove 7. An air guide hole 13 is provided on the inner surface of the left end of the housing 1. An I-shaped barrier sleeve 12 and a limiting ring 15 are fixedly connected to the left end of the inner cavity of the housing 1. A limiting block 8 is provided on the inner side of the limiting groove 7. A fixing frame 10 is fixedly connected to the left side of the limiting block 8. A positioning cylinder 6 is fixedly connected to the left side of the fixing frame 10. A filter screen 14 is provided between the positioning cylinder 6 and the limiting ring 15. A positioning sleeve 3 is threadedly connected to the right end of the outer surface of the housing 1. A barrier screen 5 is provided on the inner side of the positioning sleeve 3.

[0021] A positioning ring 2 is fixedly connected to the left end of the outer surface of the housing 1, and a limiting groove 7 is provided around the right end of the inner cavity of the housing 1.

[0022] The above technical solution, with the positioning ring 2, facilitates the installation of this device.

[0023] There are multiple air guide holes 13, and the included angle between two adjacent air guide holes 13 is equal. At the same time, the air guide holes 13 are set at an angle.

[0024] Through the above technical solutions, the air guide hole 13 can prevent water from directly entering the shell 1.

[0025] A rotating motor 9 is fixedly installed at the middle of the right side of the fixed frame 10, and a rotating blade 11 is fixedly connected to the output end of the rotating motor 9.

[0026] Through the above technical solution, the rotating blades 11 are driven to rotate by the rotating motor 9, which in turn can draw external gas into the shell 1. Then, the gas is filtered through the filter screen 14 and discharged into the hull through the barrier screen 5 in the positioning sleeve 3.

[0027] The outer surface of the positioning sleeve 3 is fixedly connected with a rotating block 4, and there are multiple rotating blocks 4.

[0028] Through the above technical solutions, the rotating block 4 facilitates the operation of the positioning sleeve 3.

[0029] In use, the air guide hole 13 prevents seawater from directly entering the shell 1, while the I-shaped barrier sleeve 12 blocks the water entering the shell 1 and allows it to be discharged again through the air guide hole 13. The rotating motor 9 drives the rotating blade 11 to rotate, thereby drawing outside air into the shell 1. Then, the air is filtered through the filter screen 14 and discharged into the hull through the barrier screen 5 in the positioning sleeve 3. When the filter screen 14 needs to be replaced, the rotating block 4 drives the positioning sleeve 3 to rotate, causing the positioning sleeve 3 to exit from the right end of the shell 1. Then, after the limiting block 8 and the fixing bracket 10 exit in the limiting slide groove 7, the positioning cylinder 6 can exit at the same time and abandon the positioning of the filter screen 14. Then, the filter screen 14 can be directly removed from the shell 1 for cleaning or replacement, which is convenient for people to use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
