Thirdly, the split unit is detachably installed by being combined with a guide member arranged outside the main screen so that the split unit can be pulled out upward. Water intake.

The sub-bars of the division unit of the sub-screen are arranged so as to be positioned on the radiation when the division unit is attached to the water intake port.

It is preferable that the sub-bars are arranged in the shape of elongated plates in a radial shape, because the rectifying effect against the inflow water is obtained and the strength is also excellent, but the sub-bars are arranged concentrically. You can also do it.

The main body and the water intake pipe can be connected not only by directly connecting the water intake pipe to the main body but also by a connection pipe.

The flow guide plate attached to the upper periphery of the main body in the shape of a horizontal collar may be formed by attaching a ring-shaped plate manufactured separately from the main body, or may be formed integrally with the main body.

When the water intake port is used for a long period of time, shellfish or the like adhere to the sub-screen arranged outside the main screen.

When removing the deposits, an operator dives into the water and separates the sub-screen for each division unit by using an underwater crane or the like and pulling it out from the main body.

Then, the detached unit is pulled up to the surface of the water, and then a maintenance work such as repainting is performed in addition to the work of scraping off the adhered substances and the repair work of the coating.

After the work is completed, the divided unit is submerged in water and attached to the body of the water intake.
