Description

Technology Field

[0001] The present invention relates to an underwater intake having a structure installed in a cooling water intake pipe and having a cap-shaped cover provided on the upper part to block the inflow of marine organisms. Background Technology

[0002] A seawater intake device having a function to remove attached organisms is disclosed in Korean Patent Publication No. 10-2023-0102581. More specifically, the seawater intake device has a function to remove attached organisms to prevent accidents in which the intake device is clogged by marine attached organisms (mussels, barnacles, green algae, seaweed, etc.) and floating foreign substances (floating organisms such as seaweed and seaweed shoveled by waves) when taking seawater from the sea in aquaculture farms, raw fish restaurants, laboratories, etc., thereby reducing or stopping the amount of water intake.

[0003] The seawater intake device includes a seawater intake tank, a circular rotating scraper, a piping device, an MSG electrode, and the entire bottom plate (500).

[0004] The seawater intake tank is composed of a perforated plate with countless holes machined at regular intervals to prevent the inflow of foreign substances during water intake.

[0005] The configuration of a flat screen water intake device for a water source connected to the intake pipes of drinking water plants, manufacturing plants, irrigation systems, and power generation facilities is disclosed in U.S. Patent Publication No. 2015-0021249.

[0006] The flat screen water intake device for a water source is mounted on the flat surface of the water source and has a water intake body with a hollow space and an outlet formed inside, and is mounted on the flat surface and has a first interior formed inside.

[0007] The configuration includes a first curved screen connected to a main body, at least one first flow regulator positioned between the first curved screen and the main body and positioned so as to communicate the first interior of the first curved screen with the hollow of the main body, and a concrete platform placed on the bottom of the water source.

[0008] When the amount of water intake decreases due to marine organisms attaching and inhabiting the area and obstructing the flow of seawater, replacing the water intake device installed on the seabed or cleaning work that requires a diver to approach underwater is cumbersome and expensive, and there are inconveniences such as having to stop using the device during cleaning.

[0009] Since the outer wall of the intake device is located on the opposite side of the seawater flow, blockage mainly occurs on the outer wall of the intake device.

[0010] Seawater intake devices are frequently clogged by attached organisms even during use, and such clogging is difficult to predict and can occur suddenly due to mobile algae, leading to secondary damage caused by the interruption of seawater supply. Prior art literature
