[0021] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0022] Specific embodiments of this application are described below with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0023] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0024] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention. The following description, in conjunction with... Figure 1-8 The preferred embodiments of the present invention will be described in further detail below: like Figure 1-8 As shown, an embodiment of the present invention provides a marine hatch escape device, comprising: The boom base 2 is fixedly mounted on the small hatch cover 1; The boom 3 is detachably fixed to the boom base 2; The lifting device 8 is detachably mounted on the boom 3 and can be lowered into the cabin along the escape passage. Due to the limited space on the upper deck 11, in order to reduce the space occupied on the upper deck 11, in this embodiment of the invention, the boom base 2 is fixedly installed at the small hatch cover 1. By integrating the boom base 2 with the small hatch cover 1, the effective space on the upper deck 11 occupied by the boom 3 is significantly reduced. Furthermore, to ensure the sturdiness of the boom 3 and reduce the installation difficulty of the boom base 2, such as... Figure 5 As shown, the boom base 2 includes at least two base plates 201. Both base plates 201 are horizontally welded to the small hatch cover plate 1, and the two base plates 201 are spaced apart. The two base plates 201 are respectively provided with mounting holes for the boom 3 to pass through, and the boom 3 is respectively fixed with an annular wing plate 4 that abuts against the base plate 201. Furthermore, in one embodiment, in order to further improve the stability of the boom 3 after installation and reduce the installation difficulty of the boom 3, the boom base 2 further includes a sleeve 202, which is inserted between two base plates 201 at the mounting hole position, and the two ends of the sleeve 202 are respectively welded and fixed to the two base plates 201. Of course, the top and bottom ends of the sleeve 202 should preferably not extend beyond the outer surface of the base plate 201. Under normal circumstances, the structural strength redundancy of the small hatch cover plate 1 is limited. Therefore, the method of directly setting the boom base 2 on the small hatch cover plate 1 has not been found. On this basis, in order to ensure the structural stability of the base plate 201 and the small hatch cover plate 1, the boom base 2 also includes several base reinforcing plates 203, which are welded and fixed between the base plate 201 and the small hatch cover plate 1. As described above, to avoid adverse effects on the hatch cover 1 caused by the load transfer of the boom 3 during use, this embodiment of the invention further optimizes the force transmission path of the boom 3 by adding a boom slot 9. The boom slot 9 is welded and fixed to the upper deck 11 directly below the mounting hole of the base plate 201. When the annular wing plate 4 abuts against the base plate 201, the end of the boom 3 is inserted into the boom slot 9. By adding the boom slot 9, part of the force on the boom 3 can be directly transmitted to the upper deck 11 through the boom slot 9. Furthermore, to ensure stable force transmission between the boom 3 and the boom base 2, the... The boom slot 9 and the end of the boom 3 are respectively provided with fixing holes. The marine hatch escape device also includes a fixing pin 10 (preferably a tongue-shaped pin). The fixing pin 10 is inserted into the fixing holes corresponding to the end of the boom 3 in the boom slot 9 to fix the boom 3 on the boom slot 9. Of course, after the boom 3 is inserted into the boom slot 9, the bottom end of the boom 3 can directly abut against the upper deck 11, or a small distance can be reserved between it and the upper deck 11. At the same time, in order to prevent the fixing pin 10, which is a small component, from falling off, the end of the fixing pin 10 is fixed to the boom slot 9 by a chain. like Figure 6 As shown, in one embodiment, the boom 3 is configured as an inverted L-shaped structure, with its upright portion connected to the boom base 2 and its crossbar extending outward to connect to the lifting device 8. Therefore, to ensure that the crossbar of the boom 3 remains stably above the escape passage during use, and that it remains stably outside the escape passage during non-use to avoid affecting its normal operation, the marine hatch escape device also includes a rotation limiting component. This component can fix the boom 3, inserted into the boom base 2, to the boom base 2, preventing the boom 3 from rotating relative to the boom base 2. Further, as... Figure 7-8As shown, the rotation limiting assembly includes a rotation limiting plate 5 fixed on the boom 3. Rotation limiting holes 6 are correspondingly provided on the rotation limiting plate 5 and the base plate 201, and two sets of rotation limiting holes 6 are provided on the base plate 201. The rotation limiting assembly also includes a rotation limiting pin 7 (preferably a tongue-shaped pin). When the rotation limiting pin 7 is inserted into the corresponding rotation limiting holes 6 of the rotation limiting plate 5 and the base plate 201, the boom 3 is in a non-rotatable state. When the rotation limiting pin 7 is inserted into one of the rotation limiting holes 6 of the base plate 201, at least a portion of the boom 3 is located above the escape passage. When the rotation limiting pin 7 is inserted into the other rotation limiting hole 6 of the base plate 201, the entire boom 3 is located outside the escape passage. Of course, in one embodiment, the end of the rotation limiting pin 7 is fixed to the boom 3 by a chain to prevent the rotation limiting pin 7 from being lost.

[0025] The embodiments of the present invention have the following beneficial effects: 1. The boom 3 and boom base 2 are designed separately, which makes it easy to store the boom 3 when it is not in use; 2. The boom base 2 is integrated with the small hatch cover, making it more convenient to use and not taking up extra space on the upper deck 11; 3. The limit and rotation switching of the boom 3 are achieved by using a tongue-shaped pin and a rotating limit plate 5, which further improves the ease of use; 4. A boom slot 9 was added, which optimized the force transmission path of the boom 3 and ensured the stability of the boom 3 and the small hatch cover 1.
