[0028] Therefore, the following solutions are proposed:
[0029] See Figure 1 , Figure 3 This utility model provides a ship anti-backflow drainage structure 100, including a check baffle 110 and a fixing member 120, wherein the top of the check baffle 110 is hinged to the fixing member 120, and the check baffle 110 covers a drainage channel 210 located on the side bulkhead 220 of the ship 200 when suspended.Figure 4 (As shown).
[0030] Specifically, in the ship anti-backflow drainage structure 100 provided by this utility model, the fixing member 120 includes at least two fixing seats 121 (e.g., three, four, or five, etc.) and a connecting rod 122. The at least two fixing seats 121 are at the same height, and the connecting rod 122 passes through the fixing seats 121.
[0031] In the ship anti-backflow drainage structure 100 provided by this utility model, the top of the check baffle 110 is provided with a through hole 111 for the connecting rod 122 of the fixing member 120 to pass through, so as to rotatably hinge the top of the check baffle 110 to the fixing member 120.
[0032] As one specific implementation method, such as Figure 1 As shown, the at least two mounting brackets 121 are fixed to the side bulkhead 220 of the vessel 200, located above the drainage channel 210.
[0033] As another specific embodiment, in the ship anti-backflow drainage structure 100 provided by this utility model, the fixing member 120 can also be arranged as follows: Figure 2 As shown, a top plate 130 is provided at the top of the drainage trough 210, and a bottom plate 140 is optionally provided at the bottom of the drainage trough 210. The fixing seat 121 of the fixing member 120 is fixed on the bottom plane of the top plate 130.
[0034] like Figure 4 The diagram shown is a three-dimensional structural schematic of a ship 200, an example type of ship with the anti-backflow drainage structure 100 provided by this utility model. The ship 200 is, for example, a deck cargo ship, a floating dock, or a landing ship. Several drainage channels 210 are provided at the locations of the side bulkheads 220 of the ship 200 to drain water accumulated on the deck. The openings of the drainage channels 210 are provided with... Figure 3 The diagram shows several blocking grilles 211.
[0035] In the anti-backflow drainage structure 100 provided by this utility model, when the check baffle 110 is suspended, its bottom is slightly higher than the bottom of the drainage channel 210. Due to the hinge between the check baffle 110 and the fixing member 120, the check baffle 110 can rotate flexibly around the fixing member 120. When the water inside the ship 200 is discharged outward, the check baffle 110 can open outward to facilitate the discharge of water from the inner deck surface of the ship 200. When the waves outside the ship 200 flow into the inner side of the ship 200 through the drainage channel 210, the check baffle 110 rotates inward, and its bottom is blocked by the blocking grille 211 and cannot be opened, thus preventing seawater from backflowing into the interior of the ship 200.
[0036] In a preferred embodiment, a rubber anti-collision pad 112 is provided on the bottom of the check baffle 110, on the side facing the drainage channel 210, to buffer the impact of its bottom on the blocking grille 211 of the drainage channel 210 when the check baffle 110 rotates inward.
[0037] This utility model provides a ship anti-backflow drainage structure in which a check baffle is hinged to a fixing member. When water on the inside of the ship is discharged outward, the check baffle opens outward to facilitate the discharge of water from the inner deck surface of the ship. When waves on the outside of the ship flow into the inside of the ship through the drainage channel, the check baffle rotates inward but is blocked by the blocking grille and cannot open, thus preventing waves from rushing back into the inner deck and improving the safety of the ship and deck workers.
[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
