[Industrial applications]

 The present invention relates to an aquarium for fish breeding, and particularly relates to improvement of an aquarium system that adopts an overflow filtration system using two aquariums, and more specifically, drains breeding water from an upper aquarium to a lower aquarium. And a fish tank system using the same.

[0002]

[Prior art]

 Filtration methods in fish tanks are roughly classified into an upper filtration method in which water is filtered by a filter installed above the aquarium, a bottom filtration method in which water is filtered by a bottom filter in the aquarium, and water in the aquarium is sealed. A closed filtration method in which the water is drawn into a filter tank of the mold, and is then returned to the water tank after filtration. Two water tanks are arranged vertically, one is used as a breeding tank and the other is used as a filtration tank. There are an overflow filtration method in which water that overflows from a predetermined water level of the breeding tank is drained to the filtration tank, and a combined filtration method in which the above methods are appropriately combined.

FIG. 5 shows an example of the configuration of a conventional device based on the above-mentioned overflow filtration method, in which a breeding tank 11 is arranged in the upper part and a filtering tank 12 is arranged in the lower part, and the inside of a drop-type drain pipe 13 made of a straight pipe. A pumping pipe 14 consisting of a small-diameter pipe is inserted into the above, and a hole for penetrating the drop-type drainage pipe 13 is provided on the bottom surface of the breeding tank 11, and the drainage pipe 13 is passed through the hole to seal the joint liquid-tightly. It will be. The upper end of the drop-type drain pipe 13 corresponds to the water level surface of the breeding tank 11, and when the water in the breeding tank 11 exceeds the upper end of the drain pipe 13, it flows into the drain pipe 13 and is drained. , The constant water level is maintained. The lower end of the drain pipe 13 enters the inside of the filter tank 12, and the drained water is guided to the filter tank 12. The water in the filtration tank 12 is pumped up into the pumping pipe 14 by the pumping motor M, and is supplied into the breeding tank 11 through the pumping pipe 14. A filtration device 15 is provided in the filtration tank 12, and the water that circulates from the breeding tank 11 to the breeding tank 11 via the drop-type drain pipe 13, the filtration tank 12, and the pumping pipe 14 is a circulation process. And is filtered by the filtering device 15.

[0004]

[Problems to be solved by the device]

 According to the above-mentioned overflow filtration method, since two aquariums are used, the total amount of water becomes larger than the capacity of the breeding tank 11 (about twice), and water pollution can be slowed down. The advantage is that the removal of waste products (ammonia, nitrous acid, nitric acid, proteins, etc.) by exchanging the breeding water and the filter material / cleaning etc. The advantage of being simple, and the advantage of being able to easily attach a water quality maintenance device such as a protein skimmer or an ultraviolet sterilization lamp to the side of the fish tank 12 without the filtration device 15 It has various advantages. On the other hand, the bottom of the breeding tank 11 has to be specially processed to allow the drop-type drain pipe 13 to pass therethrough, which is costly and the existing water tank cannot be used. . The present invention has been made in view of the above points, and solves the problems of the conventional overflow filtration type device and makes it possible to take advantage of the advantages, and a drainage pipe unit for a fish breeding tank and the same. An attempt is made to provide a fish tank system using the.

[0005]

[Means for Solving the Problems]

 A drainage pipe unit (1) for a fish tank according to the present invention communicates with an intake port (A) and the intake port (A), and is curved upward at a position higher than the intake port (A). The bending portion (B), the second bending portion (C) that communicates with the first bending portion (B), and is bent downward at a position lower than the first bending portion (B); The upward pipe section (D) leading to the second curved section (C), which is lower than the first curved section (B) and higher than the water intake port (A), is provided with a water drop section (D1). That is formed and provided with an opening (D2) that communicates with the atmosphere above the water drop portion (D1), and the water that falls from the water drop portion (D1) of the pipe portion (D) is drained downward. And a drainage section (E) forming a passage. In the fish tank system according to the present invention, the drain pipe unit (1) and the intake port (A) of the drain pipe unit (1) invade below the water surface in the tank through the upper opening of the tank. So as to receive the drainage from the drainage port (E) of the drainage pipe unit (1) at a position lower than that of the first watertank (2) arranged as described above. The second water tank (3) to be arranged and water in the tank of the second water tank (3) are pumped up, and the water is pumped into the first water tank from the upper opening of the first water tank (2). A pumping unit (M, 4) for supplying water is provided. In the present specification, the positional relationship such as upper, lower, higher, lower, etc. is a term used based on the positional relationship during normal use.

[0006]

[Action]

 As will be described later in detail in the examples, the pipe lines from the water intake (A) of the drainage pipe unit (1) to the curved portions (B, C) and the pipe portion (D) form a siphon pipe. , If the siphon pipe is filled with water and the intake port (A) is placed under the water surface of the first water tank (2), according to the siphon principle, the curved parts (B, C) from the intake port (A) ) And the pipe part (D), water flows out, falls from the falling part (D1) of the pipe line (D), and is discharged to the second water tank (3) through the drain part (E). . Here, since the opening (D2) is provided above the water drop (D1) in the pipe (D) and communicates with the atmosphere through the opening (D2), the water surface at the water drop (D1) Is formed. Therefore, when the water level of the first water tank (2) is lowered to a position corresponding to the height of the water surface of the falling portion (D1), the balance is achieved and the flow of drainage is stopped. At this time, water is retained in the pipeline from the intake port (A) to the curved portions (B, C) and the falling portion (D1) of the pipe portion (D), and the water level of the first water tank (2) is maintained. When the water level rises, the water level in the water drop section (D1) is about to rise, and the increased water automatically falls into the water discharge section (E) and is drained. In this way, the water level of the first water tank (2) is held at a fixed position based on the height of the water drop portion (D1).

Therefore, the drainage pipe unit (1) is used as a drop type drainage pipe unit for dropping the water overflowing from the first water tank (2) into the second water tank (3), and a suitable pumping unit Using (M, 4), the water in the second water tank (3) is pumped up, and water is supplied into the first water tank (2) through the upper opening of the first water tank (2). By doing so, an overflow filtration type water tank system can be easily configured, and the water level of the first water tank (2) can always be maintained at a fixed position to circulate water. Therefore, by using the drainage pipe unit (1) of the present invention, it is possible to overflow the water from the upper opening of the first water tank (2) having a curved shape, which is the same as the conventional one. It does not require any troublesome processing for penetrating the drop type drain pipe unit on the bottom of the upper water tank, and it is simple and inexpensive to use the existing water tank without any processing, and the overflow filtration method is used. It has an excellent effect that a water tank system can be easily configured.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic front view showing an embodiment of a drainage pipe unit 1 for a fish breeding aquarium according to the present invention and an embodiment of an overflow filtration type aquarium system using the drainage pipe unit 1. The drain pipe unit 1 communicates with an intake port A, a first curved part B that is curved upward at a position higher than the intake port A, and communicates with the first curved part B. A second bending portion C that is bent downward at a position lower than the first bending portion B, and an upward pipe portion D that communicates with the second bending portion C, and that is greater than the first bending portion B. A lower part and a higher part than the water intake port A, a water drop part D1 is formed, and an opening part D2 communicating with the atmosphere is provided at the upper part of the water drop part D1, and the water drop part D1 of the pipe part D. And a drainage section E forming a passage for draining water falling from the bottom. Since an opening D2 communicating with the atmosphere is provided above the water drop D1 in the pipe D, the pipe from the intake A to each of the curved portions B and C and the pipe D is a phon pipe. Has become.

In the example of FIG. 1, the pipe portion D is composed of a curved portion that is curved upward (third curved portion), and the vertex of the inner curve of the third curved portion is the water drop portion D1. The third curved portion and the drainage portion E form a continuous pipe, and the opening D2 having an appropriate size is provided at an outer curved portion of the third curved portion. ing. Thus, in this example, the drainage pipe unit 1 is composed of a series of pipes as a whole. Of course, although the drainage pipe unit 1 is made up of a series of pipes as a whole, it does not mean that the drainage pipe unit 1 is inseparable as one body, and as is known in this type of pipe, it may be disposed at an appropriate place. It may be assembled so as to be separable.

In the fish tank system shown in FIG. 1, the first aquarium 2 arranged relatively above is, for example, a breeding tank, and the ornamental fish to be raised in the tank filled with water. Alternatively, live fish are stored. The second water tank 3 arranged relatively in the lower part is, for example, a filtration tank, and is provided with a necessary filtration device 5. Of course, the vertical relationship between the breeding tank and the filtration tank may be reversed. Each of the water tanks 2 and 3 may be a normal water tank having an open top surface. The horizontal lines indicated by reference signs H1 and H2 exemplify the water levels in the respective water tanks 2 and 3.

The drain pipe unit 1 functions as a drop-type drain pipe unit that causes water overflowing from the upper water tank 2 to naturally drop into the lower water tank 3, and the water intake port A of the drain pipe unit 1 serves as the water tank 2. It is arranged so as to enter below the water surface in the tank through the upper opening of the tank. The first curved portion B of the drainage pipe unit 1 is configured to straddle the upper side surface of the water tank 2, and the second curved portion C and the pipe portion including the pipe portion D and the drainage portion E are the same as those of the water tank 2. It is exposed to the outside. The drainage port E1 located at the tip of the drainage part E is put into the second water tank 3 through the upper surface opening and drains into the water tank 3. The pumping unit that pumps the water in the second water tank 3 and supplies the water from the upper opening of the first water tank 2 into the first water tank 3 is for pumping the water in the water tank 3. It includes a submersible motor M and a pumping pipe 4 for guiding the water pumped up by the motor M toward the first water tank 2, which is known or unknown as long as it has a pumping function. Such a configuration may be used. In the figure, the upper portion 4a of the pumping pipe 4 extends laterally along the upper surface of the first water tank 2, but an upper surface filter may be provided along this. Alternatively, the upper portion 4a of the pumping pipe 4 may not be horizontally long as shown in the figure, but may simply be provided with a discharge port.

In the drainage pipe unit 1, the drainage portion E connected to the upwardly curved pipe portion D is a straight line in the drawing, but is not limited to a straight line, and may be appropriately curved or flexible. It may be any one that can be extended, and at least a part of the conduit of the drainage section E may be flexible or bendable. Similarly, the pumping pipe 4 is not limited to a straight line, and may be arbitrarily curved, flexible, or appropriately extendable. Therefore, there is no reason to arrange the second water tank 3 directly below the first water tank 2, and the second water tank 3 can be appropriately arranged. That is, the horizontal arrangement of both water tanks may be appropriately shifted so that the rearing tank 2 (or 3) is conspicuous but the filtration tank 3 (or 2) is not conspicuous.

Next, the operation and usage of this embodiment will be described. First, the both aquariums 2 and 3 are sufficiently filled with desired breeding water (the breeding water includes fresh water, seawater, water containing chemicals, etc. depending on the application). Then, as shown in the figure, the drainage pipe unit 1 is arranged so that the intake port A of the drainage pipe unit 1 is below the water surface of the water tank 2, and by appropriate means (for example, suction from the opening D2 of the pipe portion D). Or fill the siphon pipe part from the intake A of the drain pipe unit 1 to each curved portion B, C and pipe D with water, and then put the intake A below the surface of the water tank 2. Etc.), the siphon pipe portion from the intake port A to the drainage port D1 is filled with water, and the water in the first water tank 2 automatically flows out through the siphon pipe portion by the siphon principle.

According to the siphon principle, water flows out from the water intake A through the curved portions B and C and the pipe portion D, falls from the water drop portion D1 of the pipe line D, and passes through the drainage portion E to the second portion. Drained to aquarium 3. Here, since the opening D2 is provided above the water drop portion D1 in the pipe D and communicates with the atmosphere through the opening D2, a water surface is formed at the water drop portion D1. Therefore, when the water level of the first water tank 2 drops to a position corresponding to the height of the water surface of the falling portion D1, the balance is achieved and the drainage flow stops. An enlarged view of the state at this time is as shown in FIG. 2, and in the pipeline portion from the first and second curved portions B and C to the falling water portion D1 of the pipe portion (third curved portion) D. The water W is retained. Reference numeral H1 'indicates the water surface of the falling water portion D1, and is shown to be slightly higher than the water level H1 of the first water tank 2 due to the influence of surface tension or the like. When the motor M is driven to pump water, the water is supplied to the first water tank 2 through the pump pipe 4, and the water level H1 rises. As the water level H1 rises, the water surface H1 ′ of the third curved portion D also tries to rise, and the increased water flows over the inner curved point of the pipe portion (third curved portion) D, that is, the falling water portion D1. It falls over and falls into the drainage section E. In this way, the water level H1 of the first aquarium 2 is maintained at a fixed position with reference to the height of the water drop portion D1, and the breeding water is constantly circulated and filtered during the pumping drive by the motor M.

It should be noted that the above-described embodiments merely show the main part of the technical idea of the present invention, and various modifications, designs or additions are possible in the concrete implementation thereof. For example, the material of the pipe forming the drainage pipe unit 1 may be any material, and as long as a predetermined positional relationship between the curved portions can be maintained, a soft material such as a flexible material or a hard material can be used. It does not matter whether it is hard or hard. For example, the drain pipe unit 1 may be formed of an appropriate synthetic resin or the like having a certain degree of hardness so that at least the curved portions B, C, D can be fixedly held in a predetermined shape. Good. Alternatively, the drain pipe unit 1 is made of a bendable and bendable pipe material that can retain its shape when bent (for example, a bellows pipe) so that the bending portions B, C, D can be bent and stretched. May be. Alternatively, the curved portions B, C, and D of the drainage pipe unit 1 may be mutually horizontally pivoted so that they can be freely adjusted. Of course, the drain pipe unit 1 and the pumping pipe 4 may be attached to the side surface of the water tank by a suction cup or the like at a required place. Also, for example, even if the material of the pipe constituting the drainage pipe unit 1 itself cannot maintain a predetermined shape like a soft vinyl pipe, it is a support frame member made of wire or hard synthetic resin. Thus, the drain pipe unit 1 according to the present invention can be configured even if the flexible pipe is supported so that the height relationship between the curved portions B, C, and D can be maintained.

In addition, in FIG. 1 and FIG. 2, for convenience of illustration, the curved portions B, C, and D of the drainage pipe unit 1 are shown to be curved on the same plane, but the present invention is not limited to this. Of course. For example, as shown in the front view of FIG. 3A and the side view of FIG. 3B, in the drain pipe unit 1, the second bending portion C is twisted by about 90 degrees with respect to the first bending portion B. Good relationship. With this configuration, when the water intake A is inserted into the water tank 2 through the upper opening of the water tank 2, the pipe portion after the second curved portion C can be aligned with the outer surface 2a of the water tank 2. It is possible to have a compact structure with no protrusion when mounted. The shape as shown in FIG. 3 may be formed of an appropriate synthetic resin or the like having a certain degree of hardness so that it can be fixedly held in a predetermined shape, as described above. It may be formed by freely bending and extending it by a free object, or by forming the curved portions B, C, D by rotationally adjusting them by those which can be mutually rotated in the horizontal direction. May be. Of course, the drainage pipe unit 1 does not need to be configured as an inseparable pipe line, and can be separated / combined at an appropriate pipe portion like various well-known water pipes for convenient cleaning and carrying inside the pipe. You may do so. The same applies to the pumping pipe 4. In that case, for example, if the curved portions B, C, D can be separated / combined freely, it is naturally possible to make the curved portions B, C, D rotatable horizontally relative to each other as described above. It will be possible.

Further, the drainage pipe unit 1 does not necessarily have to be composed of a series of pipes as in the above embodiment, and at least the curved portions B and C and the water drop portion of the pipe portion D from the intake port A. It suffices if the siphon pipe portion leading to D1 is made up of a series of pipes (of course, the siphon pipe portion made up of this series of pipes is also an assembly of a plurality of pipe parts which are separable as described above. May be). For example, as shown in FIG. 4, the drainage pipe unit 1 is separated into a siphon pipe portion 1a extending from the intake port A to the curved portions B and C and the falling portion D1 of the pipe portion D, and a drainage portion E. May be. In this case, the end portion of the pipe portion D is entirely opened, the opening portion is the opening portion D2, and the lower end of the opening portion D2 is the falling water portion D1. In the drainage portion E in FIG. 4, the upper opening E2 thereof spreads in a funnel shape, and the end portion of the siphon tube including the second curved portion C and the pipe portion D is housed in the funnel, and the opening portion is opened. D2, that is, the water overflowing from the water drop portion D1 is collected. In this case, it is preferable that the siphon pipe portion 1a and the drainage portion E which are separated from each other can be connected to each other by an appropriate connecting tool F. In the present invention, fish is a term representative of all aquatic organisms, and is not limited to fish in a narrow sense. That is, the present invention can be applied not only to fish and shellfish but also to breeding tanks for algae, aquatic plants, seaweeds, seaweeds and other aquatic organisms.

[0018]

[Effect of device]

 As described above, according to the drainage pipe unit of the present invention, the upwardly curved first curved portion B connected to the water intake A is formed, and the siphon principle is used to open the water tank from the upper opening to the water tank side surface. In the upward pipe portion D 1 which can overflow the water by straddling and which communicates with the downwardly curved second curved portion C connected to the first curved portion B, it is lower than the first curved portion B 2. Moreover, since the water drop portion D1 is formed at a position higher than the water intake port A, and the opening D2 communicating with the atmosphere is provided at the upper side of the water drop portion D1, the water surface is formed at the water drop portion D1. Therefore, the water level of the water tank leading to the water intake A can always be automatically maintained on the water surface in the falling portion D1. Therefore, unlike the conventional one, there is no need for any complicated processing for penetrating the drop type drain pipe unit on the bottom surface of the upper water tank, and the existing water tank can be used easily and inexpensively without any processing. In addition, it is possible to easily realize an overflow filtration type water tank system, and it is possible to fully enjoy the advantages of the overflow filtration type water tank system while having a simple and inexpensive configuration.
