JP3063235U - A device to prevent clogging at the drainage port of small vessels - Google Patents

Abstract

(57) [Summary] [Purpose] By attaching to a water level holding pipe, it is possible to prevent overflow of a fish cage and to prevent the discharge of small fish for fishing bait in the fish cage. [Constitution] To maintain and maintain the water level, discharge of fine dust in the water, and cleaning of the net without removing the valve opening / closing function of the water level holding pipe.
It is characterized in that it is possible to open and close or detach the net portion.

Description

[Detailed description of the invention]

[0001]

[Problems to be solved by the invention]

 The cage for small vessels has a water intake and a drain, and the surface of the water at rest is the same as the draft of the ship. So, I installed a pipe about the length of the drain to the drain to keep the water level while driving. One side of this pipe is deformed into a rectangular shape, and also serves as a tool for opening and closing the water supply / drain valve. During high-speed driving, the drainage pressure was quite strong, and the fish was adsorbed on this rectangular part, and the drainage was hindered and water often overflowed from the cage. To prevent this, a net was placed over the rectangular part and many small holes were made on the side of the pipe. However, either the water level was too low or the small holes were clogged and the water overflowed.

[0002]

[Means for Solving the Problems]

 In order to solve the above problem, a detachable disk was attached to the rectangular part of the water level holding pipe, and a hemispherical zigzag net that could be opened and closed was attached to the disk.

[0003]

[Effect of the invention]

 When a small boat runs at high speed, the flow velocity near the drain is almost enough to attract fishing fish.However, when the present invention is installed, the outside of the net is separated from the water inlet by the radius of the ball, There is almost no drainage flow rate and no fish or debris will block the entire net. Therefore, the water does not overflow from the cage.

[Effect of the invention]

When a small boat runs at high speed, the flow velocity near the drain is almost enough to attract fishing fish.However, when the present invention is installed, the outside of the net is far from the water intake and the drain velocity is almost zero. No fish or trash will ever block the entire net. Therefore, the water does not overflow from the cage.
