Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning device for an aquarium for aquaculture. More specifically, the present invention relates to a cleaning device for an aquarium used for aquaculture of aquatic seeds and seedlings.

[Prior Art] In order to grow seeds and seedlings of aquatic organisms in aquaculture, hatched young fish are raised in a breeding tank, that is, an aquarium, for several months.

This type of aquarium is dangerous when raising young fish, such as the feed input and the excrement of the young fish settling at the bottom of the tank, disturbing the environment inside the tank and killing the young fish being raised. There is.

Therefore, it has been conventional practice to remove the sediment from the bottom of such aquariums. The cleaning was done entirely by human labor, by moving the tip of a pipe connected to a suction pump along the bottom of the tank, sucking up the sediment, and then discharging it.

Such conventional cleaning is not only extremely uneconomical in terms of costs, but also has many disadvantages, such as sucking up a large amount of the young fish being raised and damaging the young fish.

As one of the solutions to these problems,
Patent Application No. 218349 discloses that vertical rails are laid on one side wall of a rectangular aquarium, for example, vertically opposing side walls, and the system runs vertically on a pair of vertical rails. A second rail extending horizontally is laid on this moving platform, and a suction pipe that reaches the bottom of the water tank is mounted on the trolley that runs on the second rail. ,
Discloses a device for removing sediment by manipulating the bottom of the aquarium at the lower end of the suction tube.

[Problems to be Solved by the Invention] The device of the invention of this earlier application exhibits the effects described in the specification, but it is necessary to lay rails on the tops of the opposite side walls of the rectangular water tank. Therefore, when working on the side wall,
Fixed structures such as rails were a hindrance, and the cylindrical structure of the water tank was inconvenient.

[Object of the Invention] In view of the problems described above, the main object of the present invention is to provide an aquarium cleaning device whose plane is circular, that is, cylindrical.

Furthermore, an important object of the present invention is to provide a cleaning device for an aquaculture tank in which there is no fixed structure such as a rail on the top surface of the side wall of the aquarium.

[Structure of the Invention] Preferred embodiments of the invention will be described in detail with reference to the drawings. As can be seen from FIGS. 1 and 3, the aquarium 10 for aquaculture according to the present invention has a circular side wall 12, and the top surface 14 of the side wall 12 is a flat surface, and the top surface 14 of the side wall 12 is a flat surface, and the top surface 14 of the side wall 12 is a flat surface. It can be made to a certain height. A support stand 18 is formed in the center of the circular water tank 10 and projects above the water surface. Preferably, the top surface 20 of the support base 18 is flush with the top surface 14 of the side wall 12 of the aquarium 10. The support base 18 has a hollow chamber 22 as shown in FIG.
It is also possible to provide a full structure. In the water tank 10 shown in FIG. water at a constant level.

In the cylindrical aquarium 10 as described above, the cleaning device 30 of the present invention includes a pedestal 32 that bridges between the support base 18 and the side wall 12 of the aquarium. The pedestal 32 has at least two parallel rails 34 and 35, and can rotate above the circular aquarium 10 along the side wall 12 of the circular aquarium 10 about the support 18. In order to do this, a shaft member 36 is provided at the end of the pedestal 32 on the support base 18 side.
It is rotatably supported in a suitable bearing arrangement, for example a self-aligning bearing 38, which is fixed to the holder.

At the end of the side wall 12 of the water tank 10 of the pedestal 32, a wheel 40 moves on the top surface 14 of the side wall 12 to move the pedestal 32.
2, and the pedestal 32 can be rotated around the shaft member 36. As described above, the rotational movement of the pedestal 32 can be performed by a suitable motion control device 42 disposed in association with the pedestal 32.

The frame 32 has a space 44 between the two rails 34 and 35, a tub 46 provided along the outside of one of the rails 34, and one end of the tub 46 placed along the side wall 12 of the aquarium 10. It terminates in a drainage ditch 48 provided.

A moving cart 5 is mounted on the rails 34 and 35 of the pedestal 32.
0 is placed. The movable trolley 50 receives a signal from the operation control device 42 and moves the trolley 50 to the rails 34,
A drive device (not shown in the drawings) for moving along the road 35 is mounted, and an operation control device 42
A cable 52 for supplying signals or power from the mobile trolley 50 to the motor or other electric device
is wired.

The movable trolley 50 is also equipped with a water pump device 54 that can be operated in response to commands from the operation control device 42. A water suction pipe 56 is attached to the water supply pump device 54 and extends downward through the space 44 between the rails 34 and 35 to a portion approaching the bottom surface of the water tank 10. The water suction pipe 56 can be raised and lowered, or a retractable part is provided on the bottom side of the water tank 10, and the sensor 58 is attached close to the lower end of the water suction pipe 56, so that the lower end of the water suction pipe 56 is connected to the water tank 1.
It is desirable to always have a constant height above the bottom surface of 0.

[Operations and Effects of the Invention] Since the aquarium cleaning device 30 of the present invention is configured as described above, the pedestal 32 on which the movable cart 50 is mounted is arranged around the shaft portion 36, for example, as shown in FIG. While moving the mobile cart 50 in the direction shown by the arrow A, the mobile cart 50 is reciprocated on the rails 34 and 35 of the pedestal 32, that is, in the direction shown by the arrow B in FIG.
and C, and at the same time the water supply pump 54
By moving the water suction pipe 56, the water suction pipe 56 is operated on the bottom surface of the circular aquarium 10 while drawing a trajectory as shown in FIG. The waste materials settled on the bottom surface of the water tank 10 can be sucked up and drained into a drain 48 through a tub 46 provided along the rail 34.

Since the movement of the water suction pipe 56 can be appropriately controlled as necessary, the fry released in the aquarium 10 will not be harmed, and when the inside of the aquarium is manually cleaned, it is often There is no risk of attracting the large number of young fish that are seen in the water.

According to the present invention, there is no need to install rails that require special skill to install in order to guide the wheels 40 of the frame 32 around the side wall 12 of the circular water tank 10, so the construction of the device is easy. , economical.

Further, according to the present invention, since there is no fixed structure such as a rail on the top surface 14 of the side wall 12 of the circular aquarium 10, there is no hindrance when approaching the aquarium 10 from the surrounding area and performing various operations. There is an effect that there is no.
