Water is always stored.

A water supply / drainage device 5a according to another embodiment of the present invention.
The operation of will be described below. Each aquarium 1a of pool bench 1
In the case of supplying water to the inside of 1d, when the water is supplied to the inside 9a of the water supply / drainage pipe of the water supply / drainage pipe 9, the sent water passes through the outer periphery of the stop valve 29 and rises in the direction of arrow e, and is formed in the upper cylindrical body 43. Water is supplied to each of the water tanks 1a to 1d from the plurality of water passage holes 47 and 48.

When the water 49 reaches a certain water level in each of the water tanks 1a to 1d by the water supply, the float 39 in contact with the water surface 49a is lifted by buoyancy, and at the same time, the shaft 29a is also lifted and is located below the shaft 29a. Inclined surface 29 of the water stop valve 29
c comes into close contact with the inner wall surface 46a of the lower tubular body 46, and the water supply is stopped.

When the water supply is continued, the control valve 44 fixed to the shaft 29a also rises in the cylinder body 43a at the same time, but the movable valves 44c and 44d attached to the control valve 44 are raised when the control valve 44 is raised. Movable valve 44c in the body 43a
The control valve 44 is pushed down by the water pressure on the water 44d.
Since the water passage holes 44c and 44d are closed due to the close contact with the upper surface of the control valve 44, the control valve 44 itself does not rise rapidly but gradually rises, so that the water supply can be stopped smoothly. This can prevent the generation of water hammer.

When the water in each of the water tanks 1a to 1d is naturally evaporated and the water surface 49a in each of the water tanks 1a to 1d is lowered, the water supply is started. That is, when the water surface 49a of the water 49 in the water tanks 1a to 1d descends, the float 39 simultaneously descends and the shaft 29a to which the holding member 41 of the float 39 is attached.
And the control valve 44 and the water stop valve 29 fixed to the shaft 29a.
Also descends at the same time.

When the control valve 44 descends, the control valve 44
Of water existing below the control valve 44 passes through the water passage holes 44a and 44b formed in the control valve 44, pushes up the movable valves 44c and 44d, and flows out above the control valve 44 as shown by an arrow f. Since the control valve 44 gradually descends without abruptly descending, it is possible to suppress the occurrence of a water hammer generated by the water supply pressure during water supply.

By operating the nut 30 to move the holding member 41 up and down, the water level in each of the water tanks 1a to 1d can be adjusted.

The following effects can be obtained because of the structure described above. First, the pool bench currently in use can be used, and commercially available pipes and vinyl sheets can be purchased and assembled, so that it is inexpensive. Secondly, since water can be supplied and drained in a short time, the roots of the plants are not damaged, and the water level can be adjusted for each plant, so that it is possible to grow good quality plants. Thirdly, since a large number of aquariums can be formed in one pool bench by partitioning, there is an effect that many kinds of plants can be appropriately grown at the same time. Fourthly, when the water supply / drainage valve is operated, the water supply / drainage is automatically performed thereafter, so that the labor can be significantly reduced.
