Description

[Detailed Description of the Invention] The present invention relates to an aquarium equipped with an automatic ebb and flow device for breeding aquatic animals, particularly for breeding saltwater fish and shellfish.

The present inventor previously developed a breeding aquarium with an automatic ebb and flow device for breeding aquatic animals.

That is, as shown in FIG. 1, one opening 3' is provided in the water tank 1 with a slight gap from the inner surface of the ceiling 2', and the other opening 3'' passes through the ceiling 2'.
It is equipped with a U-shaped exhaust pipe 3 located higher than the outer surface, and an appropriate number of vents 5 are provided at the bottom of the side wall, with one opening 4'' extending beyond the peripheral wall of the water tank 1. located outside the aquarium 1,
We have developed an aquarium with an automatic ebb and flow device for rearing aquatic animals, which is provided with an air chamber 2 equipped with a flexible air pipe 4, the other opening 4' of which passes through the lower part of the side wall and communicates with the inside. .

In this breeding aquarium, when water is filled up to A' in the aquarium 1, water also enters the air tank 2 and the U-shaped exhaust pipe 3 up to A'. Then, when four air is pumped through the air pipe, the air is accumulated in the air tank 2, and the water in the air tank 2 and the U-shaped exhaust pipe 3 is discharged into the water tank 1, and the water in the air tank 2 is discharged. When the water reaches the B line, which coincides with the bottom of the U-shaped exhaust 3, the air accumulated in the air tank 2 is discharged into the water in the water tank 1 through the U-shaped exhaust pipe 3. At this time, if the air supply amount and exhaust amount are adjusted so that the amount of air discharged from the U-shaped exhaust pipe 3 is greater than the amount of pressurized air from the air supply pipe 4, the air in the air tank 2 will be The water in the water tank 1 gradually decreases, and at the same time the water in the water tank 1 flows into the air tank 2 through the opening 5.
As the water surface reaches line A, water also flows into the U-shaped exhaust pipe 3, closing it and returning to the initial state.
form a cycle. Note that if air is continued to be pumped from the air pipe 4, the water level in the air tank 2 will change from A to B to A.
As it goes up and down, the water surface in tank 1 also changes from A′→B′→
The tidal effect continues as it rises and falls with A'. and,
To adjust the balance between air supply amount and exhaust amount, that is, to adjust the balance between the air supply amount and the exhaust amount, for example, a Kotoku 6
The cycle of ebb and flow can be adjusted by adjusting the amount of exhaust air from the air pipe 4 and the amount of air sent from the air pipe 4.

However, when a U-shaped exhaust pipe is used, air bubbles tend to accumulate inside the pipe during ebb and flow operations, causing disturbances in the ebb and flow operation.
In other words, it was discovered that there were drawbacks such as disturbances in the vertical width of the water level and the repetition time of the water level, and that the ebb and flow repetition rate was slow, causing inconveniences such as observation. As a result of research on aquariums for breeding animals, they came up with this invention.

The present invention includes a breeding tank having a large-diameter exhaust pipe erected on the bottom, a lower part of the small-diameter exhaust pipe passing through the ceiling plate being inserted into the large-diameter exhaust pipe, and The outer wall of the first side has a gap space with respect to the inner wall of the first side, and a communication port is provided in the lower part of the outer wall and communicates with the water tank through the gap space. In the aquarium for rearing aquatic animals, which comprises an air chamber installed in the aquarium, the height of the large-diameter exhaust cylinder is such that there is a slight gap with respect to the ceiling plate of the air chamber, and The small-diameter exhaust pipe is fixed movably up and down such that the lower end of the lower part of the ceiling plate inserted into the large-diameter exhaust pipe has a gap with the bottom surface of the large-diameter exhaust pipe, and An air vent is provided in the upper part of the plate protruding from the plate, and an air adjustment pot is provided to adjust the degree of opening of the air vent, and one end of the opening communicates with the lower part of the air chamber. An air supply pipe is provided, and when water is fed into the water tank, it also flows into the air chamber, and the water level in the tank rises to the water level at the air vent of the small-diameter exhaust pipe, that is, the water level at the air chamber ceiling plate. When the air chamber, the large-diameter cylindrical body, and the small-diameter cylindrical body are also filled with water to the level of the low tide state where at least a portion of the upper surface is exposed, the water level in the air chamber reaches the upper end of the cylindrical body. When the water level is reached, air is forced into the air pipe and the water level in the air chamber is lowered to the water level at the bottom of the small-diameter exhaust pipe. This is an aquarium for rearing aquatic animals equipped with an automatic ebb and flow device, characterized in that the water is discharged into the water in the aquarium which is raised upwards.

At low tide, the water surface corresponds to the water level A line, B' is the water level line above the flow port 14 of the small diameter pipe 13, and at high tide in the water tank 11, the water level line corresponds to the water level B line. , is shown.

Since the present invention is configured as described above,
When the breeding tank 11 is filled with water selected from freshwater or seawater for aquatic animals up to the A' line water level, the water also fills the large diameter cylinder 17 and the A line in the air chamber 12 is filled with water. At the same time, the air vent 14 of the small-diameter tube body 13 is also filled, and the water is filled up to the A' line water level.

Here, when air is pumped from the air pipe 19, the pumped air is released from the air stone 20 and gradually accumulates in the air chamber 12, and the water in the air chamber 12 is passed through the flow port 18 and the gap 22 into the water tank. 1
1, the water level in the cylinder 17 gradually decreases, and when the water level A line in the air chamber 12 is finally pushed down to the water level B line that coincides with the lower end opening 13' of the small diameter pipe body 13, the water level in the cylinder 17 gradually decreases. Water level within 11
The A' line coincides with the water level B' line, and the state is high tide, and the air accumulated in the air chamber 12 is discharged through the opening 17' of the large diameter cylinder 17 for exhaust, and the lower end opening of the small diameter cylinder 13. It is discharged into the aqueous liquid in the water tank 11 through the air vent 14 and the water outlet 16 through the section 13. At this time, if you adjust the exhaust amount rather than the air supply amount so that the amount of discharged air is greater than the amount of compressed air, the air chamber 1
2 gradually decreases, and at the same time the water in the water tank 11 flows into the air chamber 12 through the gap 22 and the flow port 18, the liquid level rises and reaches line A, and the large diameter exhaust pipe 17 water flows into the pipe, and then into the small diameter exhaust pipe 1
It also flows into 3, closes it and returns to the initial state, completing one cycle of ebb and flow. Note that if the air from the air supply tube 19 continues to be pumped, the air chamber 1
The water level in tank 11 rises and falls from A to B to A, and accordingly, the water level in tank 11 also changes from A' to B' to A', and as long as air continues to be pumped, the vertical movement of the water surface, that is, the ebb and flow effect continues. By adjusting the amount of air supplied and the amount of exhaust air, the cycle of ebb and flow can be adjusted.

In addition, line A corresponds to the low tide water level line A' line.
Line B corresponds to the water level B' at high tide, so
changing the position of the small-diameter exhaust pipe 13 up and down;
That is, by changing the height of the port 14, the water levels of line B and line B' can be adjusted, and the low tide cycle can be adjusted by rotating the pot 15.
By adapting the large and small diameter vents 16 to the vents 14 of the small exhaust pipe body 13, the amount of air exhausted can be controlled and balanced with the amount of air fed from the air pipe 18 and the air stone 20. can. Furthermore, aquarium 11
When the water in the air chamber rises and falls due to the ebb and flow, the water is filtered by glass wool, sand, etc. stored in the interstitial space 22, and the air in the air chamber 12 flows through the exhaust vents 14,
16 into the water in the aquarium 11, the water in the aquarium 11 is kept fresh, and at low tide, the ceiling plate 1 of the air chamber 12 on which earth and sand are placed.
Since the rearing surface on the top of 2' is exposed to air, this device is also suitable for animals that prefer tidal flats.

According to the present invention, when using a 60 cm class aquarium, the previously developed U-shaped exhaust system has a limit of 1 hour/1 repetition, whereas the exhaust small diameter pipe and the exhaust large diameter pipe are used. Since the exhaust system is based on
One repetition is possible, and since the top of the stopcock is raised higher than the high tide water level to adjust the ebb and flow rate, the stopcock can be operated without putting hands into the water, and it is easy to manufacture, assemble, and clean. This resulted in a device that was easy to use.
