Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Please see Figures 1-8 .

[0035] To address the issues in existing technologies where the locking and sealing effect between the hatch cover and the ship's coaming 1 needs improvement, and where a large amount of unused space above the hatch cover cannot be effectively utilized, this solution provides the following technical solution: a hatch cover with a limiting structure, comprising a ship's coaming 1 and a hatch cover body 2 hinged to the upper end of the ship's coaming 1. After the hatch cover body 2 is flipped downwards, a sealing gasket 12 is fitted between it and the ship's coaming 1. A fixing mechanism 6 is located on the front side of the upper end of the ship's coaming 1, and fixing plates 4 are provided at both ends of the fixing mechanism 6. A support plate 13 is fixed to the upper end of the hatch cover body 2, and a first photovoltaic panel 14 is fixedly installed on the upper end of the support plate 13. A second photovoltaic panel 16 is telescopically connected to both the left and right sides inside the support plate 13. The fixing mechanism 6 is composed of a connecting plate 7, a movable plate 8, a connecting rod 9, a connecting cap 10, and a fixing groove 11.

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the hatch cover body 2 is engaged with the upper end of the ship coaming 1, and a sealing gasket 12 is fitted between the fixing rod 3 and the ship coaming 1. The sealing gasket 12 effectively seals the connection between the hatch cover body 2 and the ship coaming 1. Simultaneously, fixing plates 4 are fixedly connected to both the left and right ends of the front side of the hatch cover body 2. Combined with the fixing mechanism 6, the fixing plates 4 are symmetrically arranged on the left and right sides of the fixing mechanism 6. When the hatch cover body 2 needs to be opened, the connecting cap 10, which is threaded onto the outer surface of the connecting rod 9, is rotated. Move forward to move out of the fixed groove 11, thereby releasing the limit between the connecting rod 9 and the connecting plate 7. Then pull the connecting rod 9 towards the side of the vertical central axis of the connecting plate 7. The connecting rod 9 slides between the connecting plate 7 and the connecting plate 7. The connecting rod 9 drives the movable plate 8 to separate from the protrusion 5 and the fixed plate 4, thereby releasing the limit between the hatch cover body 2 and the ship coaming 1. Then hold the fixed rod 3 fixed on the front side of the hatch cover body 2 and flip the hatch cover body 2 upward. The hatch cover body 2 rotates between the hatch cover body 2 and the ship coaming 1, thereby making it easier to open the hatch cover body 2.

[0037] In addition, such as Figure 2 , Figure 7 and Figure 8 As shown, a support plate 13 is fixedly connected to the upper end of the hatch cover body 2. A first photovoltaic panel 14 is fixedly installed on the upper end of the support plate 13. Through the setting of the first photovoltaic panel 14, solar energy can be converted into electrical energy for storage, thus making good use of the empty area at the upper end of the hatch cover body 2. Moreover, by pulling the mounting plate 15 outward, the mounting plate 15 moves in the support plate 13. The mounting plate 15 drives the connecting block 17 to slide between the support plate 13. The mounting plate 15 drives the second photovoltaic panel 16 to move out of the support plate 13, increasing the actual area receiving sunlight. Then, by rotating the connecting bolt 18, the connection between the connecting block 17 and the support plate 13 is limited, and the mounting plate 15 is fixed. By adjusting the extension and retraction of the second photovoltaic panel 16, the external space can be utilized more rationally, and interference can be prevented when activities are carried out on the ship.

[0038] 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.
