Description

The present invention relates to, for example, aquarium equipment used for viewing while breeding and cultivating aquatic organisms such as ornamental fish and aquatic plants in ordinary households and the like.

In addition to aquarium fish such as ornamental fish, the aquarium for general ornamental fish, which is often used in each household, is a filtration device for adjusting the water quality and temperature to maintain the water quality above the specified quality. Equipment such as a cooler / heater is arranged. Although such equipment is indispensable for maintaining a good breeding environment, it may be annoying to the viewer and may spoil the aesthetic appearance.

Therefore, as shown in Patent Documents 1 and 2 below, aquarium equipment has been developed in which no equipment for maintaining water quality (for maintaining the breeding environment) is arranged in the ornamental aquarium. This aquarium facility consists of a main aquarium as an ornamental aquarium in which ornamental fish are bred, a sub-aquarium as an aquarium in which equipment for maintaining water quality is placed, and an forward pipe and a return pipe connecting both tanks. And a circulation pump, and by driving the circulation pump, the water in the sub tank is supplied to the main tank via the outbound pipe, and the water in the main tank is returned to the sub tank via the return pipe. ing. By circulating water between the two tanks in this way, the water quality in the main tank is maintained well without arranging equipment in the main tank.

By the way, as a conventional water tank facility having two water tanks as shown in Patent Documents 1 and 2, an ornamental water tank and an instrument water tank are arranged on the base, and the water tank goes inside the base. A water tank facility in which pipes and return pipes are buried has been proposed. In this water tank facility, a discharge port for an outgoing pipe and a water suction port for a return pipe are provided on the bottom surface of the main water tank, and water from the sub water tank is discharged from the discharge port and supplied to the main water tank.

In such a water tank facility, if the opening area of the discharge port provided on the bottom surface of the main water tank is formed large, the momentum of the water discharged from the discharge port becomes weak, so that the so-called shortcut, that is, the water discharged from the discharge port is released. There is a possibility that an unfavorable phenomenon may occur in which the water is immediately sucked from the water inlet without circulating in the main water tank. Therefore, it is necessary to form a small opening area of the discharge port to sufficiently secure the momentum of the discharged water. However, if the opening area of the discharge port is reduced, it becomes difficult to insert a cleaning tool or the like from the discharge port, and there is a problem that maintenance and inspection such as cleaning around the discharge port in the forward pipe cannot be performed reliably. It was.

The present invention has been made in view of the above problems, and ensures sufficient maintenance and inspection around the discharge port in the outbound pipeline while sufficiently ensuring the momentum of water from the discharge port provided on the bottom surface of the main water tank.

As shown in FIGS. 1 and 2, the main water tank peripheral wall body 20 attached to the main water tank side recess 21 in the base 1 constitutes four surrounding walls of the main water tank 2, and is a cylinder in which both upper and lower ends are open. It is formed in a shape (square cylinder shape). The main water tank peripheral wall body 20 is made of a transparent glass plate or a synthetic resin plate, and has a horizontal plane shape (horizontal cross-sectional shape) corresponding to the plane shape of the main water tank side recessed portion 21. The lower end of the main water tank peripheral wall body 20 is fixed in a state of being fitted into the main water tank side recessed portion 21. A paste-like or paste-like silicone-based sealant (not shown) is filled and applied between the lower end of the main water tank peripheral wall 20 and the peripheral edge of the main water tank side recess 21 to fill and apply the main water tank peripheral wall 20.

Here, in the present embodiment, the sub water tank 3 as an instrument water tank is formed by the sub water tank peripheral wall body 30 and the bottom surface of the sub water tank side recessed portion 31.

As shown in FIGS. 1 to 4, on the bottom surface 22 of the main water tank 2, the discharge nozzle 23 is detachably attached to the outflow hole 42 of the discharge port closing lid 41, and the inflow hole 52 of the suction port closing lid 51 is attached. A strainer pipe (pipe with strainer) 24 is detachably attached. As a result, the water in the outbound pipe 4 is discharged into the main water tank 2 via the discharge nozzle 23, and the water in the main water tank 2 is sucked into the return pipe 5 via the strainer pipe 24. ing. The parts provided on the main water tank 2 side, such as the discharge nozzle 23 and the strainer pipe 24, are preferably made of a transparent material so as not to stand out.

Further, on the bottom surface 32 of the sub water tank 3, a strainer pipe (pipe with a strainer) 34 is detachably attached to the return pipe discharge port 5b, and the water in the return pipe 5 is attached to the sub water tank via the strainer pipe 34. It is designed to be sucked into 3.

Further, a discharge pump 15 as a circulation pump is installed on the bottom surface 32 of the sub water tank 3. The discharge port of the discharge pump 15 is arranged so as to be fitted into the outbound pipeline suction port 4a on the bottom surface 32 of the sub water tank, and the suction port of the discharge pump 15 is arranged so as to open in the sub water tank 3. .. Therefore, the water in the sub water tank 3 is sucked into the discharge pump 15 and discharged into the outgoing pipe 4 through the outgoing pipe suction port 4a.

Further, a filter (filtration device) 16 is arranged between the discharge pump 15 and the strainer pipe 34 in the sub water tank 3 so as to partition the two, and is sucked into the sub water tank 3 from the return pipe discharge port 5b. The water is filtered through the filter 16 and then discharged from the outbound pipeline suction port 4a by the discharge pump 15.

In the water tank equipment of the present embodiment configured as described above, both the main water tank 2 and the sub water tank 3 are open to the atmosphere, and both water tanks 2 and 3 are communicated through the outbound pipe 4 and the return pipe 5. It is connected in communication. Therefore, the water stored in the main water tank 2 and the sub water tank 3 has the same water level and the same water surface height.

Then, in this water tank facility, when the discharge pump 15 is driven, the water in the sub water tank 3 is sucked by the discharge pump 15 and discharged into the outgoing pipeline 4 from the suction port 4a. The water discharged into the outbound pipe 4 passes through the outbound pipe 4, passes through the outflow hole 42 of the closing lid 41 provided in the discharge port 4b of the bottom surface 22 of the main water tank, and enters the main water tank 2 from the discharge nozzle 23. Be supplied.

When water is supplied from the sub tank 3 into the main tank 2 in this way, the same amount of water as the supplied amount is automatically returned from the main tank 2 to the sub tank 3 via the return pipe 5. That is, the water in the main water tank 2 is sucked into the return pipe 5 from the inflow hole 52 of the closing lid 51 provided in the suction port 5a via the strainer pipe 24, and the water passes through the return pipe 5. It is sucked into the sub water tank 3 from the discharge port 5b of the bottom surface 32 of the sub water tank via the strainer pipe 34. The water sucked into the sub water tank 3 is filtered through the filter 16 and then sucked into the discharge pump 15 in the same manner as described above and discharged into the outbound pipe line 4.

By circulating water between the main tank 2 and the sub tank 3 in this way, the water quality in the main tank 2 is maintained in a good state without arranging instruments such as filters in the main tank 2. be able to. Therefore, aquatic organisms such as ornamental fish can be bred in the main aquarium 2 under a favorable breeding environment. Further, since a filter, a circulation pump, or the like that hinders the viewing is not arranged in the main water tank 2, a good aesthetic appearance can be obtained for the viewer.

Further, in the water tank equipment of the present embodiment, the discharge port 4b on the bottom surface 22 of the main water tank is closed by the discharge port closing lid 41, and water is discharged into the main water tank 2 from the outflow hole 42 formed in the closing lid 41. I am trying to do it. Therefore, since the opening area of the outflow hole 42 that substantially functions as the discharge port 4b can be reduced, the momentum of the water discharged from the outflow hole 42 into the main water tank 2 can be sufficiently strongly secured. Therefore, the water discharged from the outflow hole 42 is largely circulated in the main water tank 2 and then sucked in from the suction port 5a (inflow hole 52) of the return pipe 5, effectively preventing the occurrence of a shortcut. can do.

Moreover, in the water tank equipment of the present embodiment, since the discharge port closing lid 41 is detachably attached to the discharge port 4b on the bottom surface 22 of the main water tank, the entire area of the discharge port 4b can be opened by removing the discharge port closing lid 41. As a result, the discharge port portion of the outgoing pipeline 4 can be greatly opened. Therefore, by removing the discharge port closing lid 41, the vicinity of the discharge port of the outgoing pipeline 4 can be easily cleaned, and maintenance and inspection around the discharge port can be performed reasonably and reliably.

Further, in the water tank equipment of the present embodiment, since the suction port 5a on the bottom surface 22 of the main water tank is closed by the suction port closing lid 51 with an inflow hole, the opening of the inflow hole 52 that substantially functions as the suction port 5a. The area can be reduced, the inflow hole 52 (suction port 5a) can be prevented from being conspicuous, and the aesthetic appearance can be further improved. Further, by removing the suction port closing lid 51, the entire area of the suction port 5a can be opened widely, so that the area around the suction port of the return pipe 5 can be easily cleaned in the same manner as described above, and maintenance and inspection around the suction port can be performed. It can be done reasonably and reliably.

However, in the present invention, it is not always necessary to attach the closing lid 51 to the suction port 5a of the return pipe 5, and the relatively large suction port 5a may be left as it is on the bottom surface 22 of the main water tank. A plate-shaped strainer member may be directly attached so as to close the large suction port 5a.

Further, in the water tank equipment of the present embodiment, the groove shape is formed so as to bridge the discharge port 4b on the main water tank 2 side and the suction port 4a on the sub water tank 3 side on the back surface side of the upper plate 11 of the base 1. The outbound pipe member 40 is attached to form the outbound pipe 4, and the groove-shaped return pipe member 50 is provided so as to bridge between the suction port 5a on the main water tank 2 side and the discharge port 5b on the sub water tank 3 side. Since it is attached to form the return pipeline 5, the forward pipeline 4 and the return pipeline 5 can be easily formed by simply attaching the groove-shaped pipeline members 40 and 50 to the back surface of the base 1. As a result, the entire aquarium equipment can be manufactured efficiently and easily.

Further, in the water tank facility of the present embodiment, the silicon-based sealing material 7 is filled between the upper opening peripheral edge of the groove-shaped pipeline members 40 and 50 and the back surface of the upper plate of the base 1, and the space between them is closely adhered. Since it is fixed, it is possible to manufacture the forward pipe 4 and the return pipe 5 with high work efficiency and excellent watertightness, and it is possible to reliably provide high-quality water tank equipment without water leakage or the like.

Further, when attaching the pipeline members 40 and 50 to the base 1, after applying the sealing material 7 to the upper opening peripheral edges of the pipeline members 40 and 50, screwing formed on the outer peripheral edges of the pipeline members 40 and 50. Since the piece 63 is screwed and fixed to the screwed portion 13 of the base 1 by the screw 71, the pipeline members 40 and 50 are attached to the base 1 even in the state before the sealing material 7 is cured. It can be fixed in a stable state. Therefore, it is not necessary to leave the sealing material 7 until it is cured, and the next manufacturing process can be carried out as it is in the state before curing. Since the sealing material 7 can be treated without considering the curing time in this way, the water tank equipment can be efficiently assembled in a short time, and the production efficiency can be improved. In some cases, it is possible to ship the sealant 7 as a product even before it has hardened.

Further, in the above embodiment, the main water tank 2 and the sub water tank 3 are formed in a tubular shape so that the horizontal cross-sectional shape does not change regardless of the height position, but the present invention is not limited to this. For example, in the present invention, as the main tank and the sub tank, the horizontal cross-sectional shape and size change depending on the height position, such as a cone shape, a truncated cone shape, a pyramid shape, a truncated cone shape, a drum shape, and a barrel shape. You may use something like that.

Further, it is not necessary to form the main water tank 2 and the sub water tank 3 in the same shape as each other. For example, one water tank may have a circular cross section and the other water tank may have a rectangular cross section.

Further, in the above embodiment, the case where all four peripheral walls of the front, rear, left and right of the main water tank 2 are formed transparently has been described as an example, but the present invention is not limited to this, and in the present invention, at least a part of the main water tank 2 is formed. Region For example, only one side wall needs to be transparently formed.
