Description

Technical Field

[0001] This utility model relates to the fields of aquaculture and marine engineering, specifically proposing a special device for drawing seawater from the deep sea and applied to the deck of an aquaculture vessel. Background Technology

[0002] With the continuous development of large-scale deep-sea aquaculture facilities technology, especially with the increasing application of aquaculture workboats in the deep-sea aquaculture industry, the industry is showing multiple development directions, such as optimizing ship design, increasing the volume of aquaculture water on workboats, improving automation and aquaculture efficiency, and reducing aquaculture costs.

[0003] Existing deep-sea aquaculture vessels typically employ a closed-hull structure. Water is drawn into the hull through an inlet at the bottom, then pumped into the hull before being supplied to the various aquaculture tanks. Since cold-water fish farming requires water from deeper waters, one or more pipes need to be extended 30-40 meters below sea level. This places high technical standards on the efficiency of lowering and retrieving these pipes from the hull, including requirements for convenient and quick deployment and retrieval, ensuring the pipes do not extend beyond the ship's side during navigation, and ensuring efficient, economical, and durable operations. Currently, the equipment configuration of aquaculture vessels has not effectively addressed these issues.

[0004] In view of the above, this patent application is hereby filed. Utility Model Content

[0044] Based on the structure design of the deck water taking device of the culture work ship, the following taking and placing process of the elbow assembly can be realized:

[0045] 1) the retracted state;

[0046] Gear motor 160 drives gear ring 162 to make second elbow 151 in vertical position, hydraulic cylinder 141 drives piston 142 to make rotary arm 130 move, at the same time, electric hoist 140 moves and makes third elbow 152 all above deck 101 through pull cable 159, that is, according to the regulation of ship industry, the elbow assembly is all above deck 101.

[0047] 2) half-lowering state;

[0048] Gear motor 160 drives gear ring 162 to make second elbow 151 rotate in counterclockwise direction, at the same time, hydraulic cylinder 141 drives piston 142 to make rotary arm 130 move, at the same time, electric hoist 140 moves and makes the center line of third elbow 152 in horizontal position through pull cable 159.

[0050] Electric hoist 140 continues to move and makes third elbow 152 rotate in clockwise direction through pull cable 159, and water suction port 163 rotates and extends to the required depth below sea level.

[0051] It should be noted that pull cable 159 can adjust the extension depth of water suction port 163 of third elbow 152, and can also resist the impact of water flow on third elbow 152 (long pipe part). Because during cultivation, the work ship is single-point mooring, and the water flow is from bow to stern direction.

For those skilled in the art, they can be inspired by this and directly deduce other alternative structures that meet the design concept of the present application. Other structural features obtained thereby should also belong to the scope of the present application.
