[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0026] Reference Figures 1-4 As shown, this utility model discloses a fixing device for an anti-smuggling underwater gate grille, comprising:

[0027] Grating 1;

[0028] Support part 2, the support part 2 includes mounting frame 21, mounting base 22 and bolt 23. Multiple mounting bases 22 are provided along the inner side of mounting frame 21. Bolt 23 passes through grid plate 1 and is connected to mounting base 22. Nut 24 is provided on the side of mounting base 22 away from grid plate 1. Nut 24 is sleeved on the outside of bolt 23.

[0029] The locking part 3 includes a fixing plate 31 and a clamping plate 32. The fixing plate 31 is disposed on the side of the grid plate 1 away from the mounting base 22. The fixing plate 31 is attached to the bolt 23. One side of the fixing plate 31 is connected to the mounting frame 21, and the other side of the fixing plate 31 is connected to the clamping plate 32. The side of the clamping plate 32 away from the fixing plate 31 is bent to form a clamping edge 321. The clamping plate 32 passes through the grid plate 1, and the clamping edge 321 is fastened to the side of the grid plate 1 near the mounting base 22.

[0030] The support part 2 in this utility model is used for installing the grating plate 1. Specifically, multiple mounting seats 22 are arranged circumferentially on the inner side of the mounting frame 21. The outer edge of the grating plate 1 is connected to the mounting seats 22 by bolts 23, fixing the grating plate 1 to the mounting frame 21. The locking part 3 is used to fix and protect the bolts 23. The locking part 3 is installed after the grating plate 1 is installed. Specifically, the fixing plate 31 is attached to one end of the bolt head of the bolt 23, and one side of the fixing plate 31 is connected to the mounting frame 21. The other side of the fixing plate 31 is connected to the clamping plate 32. After the fixing plate 31 and the clamping plate 32 are connected, they form a "7" shape. The function of the entire clamping plate 32 is to fix the side of the fixing plate 31 away from the mounting frame 21. The side of the clamping plate 32 away from the fixing plate 31 is bent to form a clamping edge 321. In the actual installation process, the side of the clamping plate 32 with the clamping edge 321 is passed through the grid hole on the surface of the grating plate 1, and then the clamping edge 321 is fastened to the inner side of the grating plate 1 (the side closer to the mounting base 22). Finally, the fixing plate 31 is welded and fixed to the mounting frame 21. The bolt 23 is encapsulated inside the fixing plate 31. In the event of smuggling, even if the internal nut 24 is damaged, the seabed gate cannot be opened, greatly eliminating the possibility of smuggling.

[0031] The installation of the locking part 3 in this utility model does not affect the original installation of the grating plate 1. The bolt 23 can be sealed by the fixing plate 31 and the clamping plate 32. Even if the nut 24 on the inner side of the grating plate 1 is damaged, the sea gate cannot be opened, which greatly eliminates the possibility of smuggling.

[0032] As a preferred embodiment of this utility model, both the fixing plate 31 and the clamping plate 32 are made of stainless steel flat iron strips. If the ship needs maintenance, it can be easily cut open from the outside with a cutting machine, and it is also convenient for maintenance. There is no situation where it cannot be opened.

[0033] Furthermore, an annular retaining plate 33 is provided on the side of the fixing plate 31 that is in contact with the bolt 23, and the annular retaining plate 33 is fastened to the outside of the screw head of the bolt 23.

[0034] Specifically, during actual installation, the annular locking plate 33 is fastened to the outside of the nut of the bolt 23 to seal the nut portion of the bolt 23 and provide protection for the nut.

[0035] Furthermore, the nut 24 is fixedly connected to the mounting base 22.

[0036] Specifically, in this utility model, the nut 24 and the mounting base 22 are fixed by spot welding, which can prevent the nut 24 from loosening and falling off during the ship's operation; secondly, during the installation of the grating plate 1, the bolt 23 can be directly inserted and connected to the nut 24, which facilitates the installation of the grating plate 1.

[0037] Furthermore, the fixing plate 31 and the clamping plate 32 are integrally formed.

[0038] Specifically, both the fixing plate 31 and the clamping plate 32 are made of 316L stainless steel flat iron strips. The fixing plate 31 and the clamping plate 32 are integrally formed. The stainless steel flat iron strips are stamped into a “7” shape by a bending machine, and the clamping edge 321 is stamped out at the same time.

[0039] Furthermore, a rotating pin 5 is provided between one side of the grille plate 1 and the mounting frame 21.

[0040] Specifically, both the entire grille plate 1 and the mounting frame 21 are rectangular structures. To facilitate the opening and closing of the grille plate 1, the grille plate 1 is connected to the mounting frame 21 via a rotating pin 5. As a preferred embodiment of this utility model, one side of the grille plate 1 is rotatably connected to the mounting frame 21 via a rotating pin 5, and the remaining three sides are used for the installation of the locking part 3. In this utility model, there are seven sets of fixing plates 31 and clamping plates 32, one set on the opposite side of the rotating pin 5, and three sets on each of the remaining two sides.

[0041] Furthermore, the outer edge of the grating plate 1 is provided with a connecting hole 11 that mates with the bolt 23. During installation, the bolt 23 is passed through the connecting hole 11 and then inserted into the mounting base 22.

[0042] Furthermore, the fixing plate 31 is arranged parallel to the grid plate 1, the clamping plate 32 is arranged perpendicular to the fixing plate 31, and the clamping edge 321 is arranged perpendicular to the clamping plate 32. This allows the clamping plate 32 to fit better with the grid plate 1. In actual installation, the dimensions of the fixing plate 31 and the clamping plate 32 can be appropriately increased or decreased according to the gap size of the grid plate 1 and the size of the bolts 23 to meet the actual needs of the final installation. Example 2

[0043] A vessel includes the anti-smuggling underwater gate grating fixing device described in Embodiment 1, and also includes a hull 4. The mounting frame 21 is installed at the bottom of the hull 4, and the grating plate 1 is installed as an underwater gate within the mounting frame 21. Specifically, the bottom of the hull 4 has a notch that mates with the mounting frame 21.

[0044] In summary, this utility model introduces an anti-smuggling underwater gate grating fixing device and a vessel. The specific installation process is as follows: First, the grating plate 1 is connected and fixed by bolts 23. Then, the side of the retaining edge 321 with the retaining edge 321 is engaged with the grating plate 1, so that the annular retaining platform 33 inside the fixing plate 31 is fastened to the nut of the bolt 23. Finally, the fixing plate 31 is welded and fixed to the mounting frame 21. In this utility model, the entire anti-smuggling device does not affect the original installation of the grating plate 1. Secondly, the structure of the entire anti-smuggling device is simple, convenient to manufacture and install. The bolts 23 can be sealed by the fixing plate 31 and the retaining plate 32. Even if the nut 24 on the inner side of the grating plate 1 is damaged, the underwater gate cannot be opened, greatly eliminating the possibility of smuggling.
