Problems solved by technology

[0003] At present, the known suction grille is more suitable for medium and low-speed ships. For high-speed sailing ships, no matter whether the ship is in the high-speed forward working condition or the fast reverse working condition, the water intake efficiency is low, and it cannot fully meet the water requirements of various equipment and systems of displacement high-speed ships. Demand, especially when the ship sails at high speed, when it is necessary to quickly avoid or reverse quickly, if the ship's sea valve box is equipped with ordinary suction grids, it cannot meet the water intake requirements, resulting in serious safety hazards during the ship's navigation

Embodiment 1

[0026] Such as Figure 1-2 As shown, the present embodiment provides a marine high-efficiency water intake device, which includes a frame 1 for connecting with the sea valve box, and also includes a front grille 2 and a rear grille 3 respectively connected to both ends of the frame 1. The frame 1, the front grid plate 2 and the rear grid plate 3 form a triangular space, a certain angle of forward inclination is formed between the front grid plate 2 and the frame 1, and a certain angle of back inclination is formed between the rear grid plate 3 and the frame 1, The connection between the front grid 2 and the rear grid 3 is also provided with a water blocking plate for pocketing water. The water blocking plate is located in the triangular space. This device can effectively improve the water inlet efficiency of the sea valve box, especially When the ship is sailing at high speed, whether it is in the forward or reverse condition, it can realize efficient water intake to meet the ...

Embodiment 2

[0031] Such as Figure 3-4 As shown, the difference between this embodiment and Embodiment 1 is that the water blocking plate is a wedge-shaped plate 5, and one side of the small thickness of the wedge-shaped plate 5 is connected to the frame 1, no matter whether the ship is advancing or retreating, the The above-mentioned wedge-shaped plate 5 can play a good role in pocketing water, forming a positive pressure head near the front grid plate 2 or the rear grid plate 3 and the wedge-shaped plate 5, so as to promote seawater to enter the sea valve box more easily, and improve the water inlet device. water intake efficiency. Further, the wedge plate 5 has an inclined streamlined curved surface, which has less resistance to the navigation of the ship and is more practical.

Embodiment 3

[0033] Such as Figure 5-6 As shown, the difference between this embodiment and Embodiment 1 is that the water blocking plate is a movable straight plate 6, one end of the movable straight plate 6 is hinged with the junction of the front grid plate 2 and the rear grid plate 3, and the other end can be Free swing within a certain angle range. When the ship is moving forward, the movable straight plate 6 is in a backward tilting state, and when the ship is retreating, the movable straight plate 6 is in a forward tilting state, further, the frame 1 is provided with a limiter for limiting the swing range of the movable straight plate 6 Block 7. No matter the ship is in the process of advancing or retreating, the movable straight plate 6 can play a good role in pocketing water, and a positive pressure head is formed near the front grid plate 2 or rear grid plate 3 and the movable straight plate 6, so as to promote seawater to enter more easily In the sea valve box, the water inle...

Abstract

The invention relates to the technical field of ship tools, in particular to an efficient water feeding device for a ship. The efficient water feeding device comprises a frame for being connected with a sea valve box, and further comprises a front grating plate and a back grating plate which are connected with the two ends of the frame respectively. Triangle space is formed by the frame, the front grating plate and the back grating plate, a certain front inclination angle is formed between the front grating plate and the frame, a certain back inclination angle is formed between the back grating plate and the frame, and a water intercepting plate for catching water is further arranged at the connecting portion between the front grating plate and the back grating plate, and is located in the triangle space. By means of the efficient water feeding device, the water feeding efficiency of the sea valve box can be effectively improved, and particularly, when the ship is in the high-speed shipping state, whether the ship is in the advancing working condition or in the retrogressing working condition, efficient water feeding can be achieved, the water requirement of all devices and all systems of a water-draining-type high-speed ship is met, and it is guaranteed that the ship is in the airworthiness state; meanwhile, large sundries can be stopped from entering a seawater valve box, the preliminary filter effect is achieved, and the powerful guarantee is provided for the high shipping speed and the safety of the ship.

Description

technical field [0001] The invention relates to the technical field of ship tooling, in particular to a high-efficiency water inlet device applied to a ship sea valve box system. Background technique [0002] A displacement ship is a ship that sails on the water surface or in water, and its weight is entirely supported by the buoyancy of the water, also known as a floating ship. During the navigation process, its various equipment and systems require a lot of water to ensure that the ship is in a good seaworthy state . [0003] At present, the known suction grille is more suitable for medium and low-speed ships. For high-speed sailing ships, no matter whether the ship is in the high-speed forward working condition or the fast reverse working condition, the water intake efficiency is low, and it cannot fully meet the water requirements of various equipment and systems of displacement high-speed ships. Demand, especially when the ship sails at high speed and needs to quickly ...
