Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a seawater intake / exhaust device in an on-board fish tank in which seawater is replaced using a dispersion plate.
[0002]
[Prior art]
In the conventional seawater intake / exhaust device in the fish tank, the sliding groove provided on the inner side wall of the left and right side frame of the bottomed frame body slides on the left and right side edges of the lid having a difference in thickness. Pressing by the locking protrusions of the water to close the water inlet and the lid, drain the work in the fish tank, and cover the upper surface of the bottomed frame with a dispersion plate having many pores Thus, there has been proposed a method in which seawater pressure from the outside of the ship is dispersed by a dispersion plate and seawater is fed into the fish tank (see, for example, Japanese Utility Model Publication No. 6-34232).
[0003]
[Problems to be solved by the invention]
In Japanese Utility Model Publication No. 6-34232, since the lid is locked by the locking projection of the sliding groove, the locking projection is worn and the bottomed frame itself must be replaced each time. There was a problem of cost.
Also, when performing drainage work in the fish tank, the lid is moved to the upper surface of the water inlet by pulling the rope, the lid is locked by the locking projection, and the seawater is pumped up by the pipe by driving the pump to the outside of the ship. After draining, the bolts are removed, the dispersion plate is removed from the frame body, and the pressure bolt provided at the center of the narrow pressure plate laid between the left and right side frames is rotated above the water intake port in the direction of the lid to cover the water intake port. In order to prevent the intrusion of seawater completely, and to absorb water, on the contrary, after rotating the pressing bolt upward, attach the dispersion plate to the frame with the bolt and move the lid by pulling the rope. Since the water inlet was opened, the intrusion of seawater into the fish tank could be completely blocked, but there was a problem that labor was required for removing and attaching the dispersion plate.
Also, when the seawater temperature is low, even if the water pressure is dispersed with a dispersion plate, the seawater flows directly above, so the seawater with a low water temperature hits the fish and the fish's health cannot be reliably maintained. there were.
[0004]
The present invention is capable of easily performing the intake and discharge operations in the fish tank without removing the bolts from the framed body and removing the bolts from the framed body for many years, and even when the seawater temperature is low. An object of the present invention is to provide a seawater intake / exhaust device in an on-board fish tank capable of maintaining the health of the fish.
[0005]
