[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0030] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0031] It should also be understood that although the present application has been described with reference to certain specific examples, those skilled in the art will be able to implement many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0032] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0033] Specific embodiments of the present application will be described below with reference to the accompanying drawings; however, it should be understood that the embodiments described are merely examples of the present application and may be implemented in a variety of ways. Familiar and / or repetitive functions and structures are not described in detail to clarify the true intent based on the user's historical operations and to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details described herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any appropriate detailed structure.

[0034] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0035] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-8 , the preferred embodiments of the present invention are further described in detail:

[0036] like Figure 1-8 As shown, an embodiment of the present invention provides a small hatch cover escape device for a ship, comprising:

[0037] A boom base 2, wherein the boom base 2 is fixedly arranged on the small hatch cover coaming 1;

[0038] A boom 3, wherein the boom 3 is detachably fixed to the boom base 2;

[0039] a sling 8, which is detachably mounted on the boom 3 and can be lowered into the cabin along the escape passage;

[0040] Since the space on the upper deck 11 is limited, in order to reduce the space occupied by the upper deck 11, in the embodiment of the present invention, the boom base 2 is fixedly arranged on the small hatch cover coaming 1. By integrating the boom base 2 with the small hatch cover coaming 1 into an integrated design, the effective upper deck 11 space occupied by the boom 3 is greatly reduced. On this basis, in order to ensure the firmness of the boom 3 and reduce the difficulty of installing the boom base 2, as shown in FIG. Figure 5 As shown, the boom base 2 includes at least two base plates 201, both of which are horizontally welded to the small hatch cover coaming 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 correspondingly fixed with an annular wing plate 4 that abuts against the base plates 201;

[0041] Furthermore, in one embodiment, in order to further improve the firmness of the boom 3 after installation and reduce the difficulty of installing the boom 3, the boom base 2 further includes a sleeve 202. The sleeve 202 is inserted between the two base plates 201 at the location of the installation hole, and the two ends of the sleeve 202 are respectively welded to the two base plates 201. Of course, the top and bottom ends of the sleeve 202 are preferably not beyond the outer plate surface of the base plate 201.

[0042] Generally, the structural strength redundancy of the small hatch cover coaming 1 is limited. Therefore, a method of directly arranging the boom base 2 on the small hatch cover coaming 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 coaming 1, the boom base 2 also includes a plurality of base reinforcement plates 203. The base reinforcement plates 203 are welded and fixed between the base plate 201 and the small hatch cover coaming 1.

[0043] As described above, in order to prevent the load transfer of the boom 3 in use from adversely affecting the small hatch cover coaming 1, the embodiment of the present invention further optimizes the force transmission path of the boom 3, and further adds a boom slot 9, which is welded and fixed to the upper deck 11 just 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 transferred to the upper deck 11 through the boom slot 9. Furthermore, in order to ensure stable force transmission between the boom 3 and the boom base 2, the The boom slot 9 is provided with a fixing hole corresponding to the end of the boom 3. The marine small hatch cover escape device further includes a fixed limit pin 10 (preferably a tongue-shaped pin). The fixed limit pin 10 is inserted into the fixing hole corresponding to the boom slot 9 and the end of the boom 3 to fix the boom 3 to 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 rest on the upper deck 11, or a small distance can be reserved between the boom 3 and the upper deck 11. At the same time, in order to avoid the fixed limit pin 10 as a small component from falling off, the end of the fixed limit pin 10 is fixed to the boom slot 9 by a chain.

[0044] like Figure 6 As shown, in one embodiment, the boom 3 is configured as an inverted L-shaped structure as a whole, the upright portion of which is connected to the boom base 2, and the cross bar portion thereof extends outwardly for connecting to the sling 8. Based on this, in order to ensure that the cross bar portion of the boom 3 can always be stably located above the escape passage when in use, and at the same time, when not in use, the cross bar portion of the boom 3 can always be stably located outside the escape passage so as not to affect the normal use of the escape passage, the marine small hatch cover escape device also includes a rotation limit assembly, which can fix the boom 3 inserted on the boom base 2 on the boom base 2 to prevent the boom 3 from rotating relative to the boom base 2. Further, as Figure 7-8 As shown, the rotation limit assembly includes a rotation limit plate 5 fixed on the boom 3, and rotation limit holes 6 are correspondingly provided on the rotation limit plate 5 and the base plate 201, and two groups of rotation limit holes 6 are provided on the base plate 201. The rotation limit assembly also includes a rotation limit pin 7 (preferably a tongue-shaped latch). When the rotation limit pin 7 is correspondingly inserted in the rotation limit space 6 aligned with the rotation limit plate 5 and the base plate 201, the boom 3 is in a non-rotatable state. When the rotation limit pin 7 is inserted in one of the rotation limit holes 6 of the base plate 201, at least part of the rod body of the boom 3 is located above the escape passage. When the rotation limit pin 7 is inserted in another rotation limit hole 6 of the base plate 201, the entire rod body of the boom 3 is located outside the escape passage. Of course, in one embodiment, the end of the rotation limit pin 7 is fixed to the boom 3 by a chain to prevent the rotation limit pin 7 from falling off.

[0045] The embodiments of the present invention have the following beneficial effects:

[0046] 1. The boom 3 and the boom base 2 are designed to be separated, which makes it easy to store the boom 3 when not in use;

[0047] 2. The boom base 2 is integrated with the small hatch cover, making it more convenient to use without taking up additional space on the upper deck 11;

[0048] 3. The use of tongue-shaped latch and rotation limit plate 5 to achieve the limit and rotation switching of the boom 3 further improves the convenience of use;

[0049] 4. The boom slot 9 is added to optimize the force transmission path of the boom 3 and ensure the stability of the boom 3 and the small hatch cover coaming 1.
