DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing refuse such as fallen leaves floating on the surface of a garden pond or the like.

[0002]

2. Description of the Related Art Circulating and filtering devices for pond water such as garden ponds are well known. Japanese Utility Model Publication No. 56-12984 is one such example. There are also known devices for introducing and extracting surface water from a water tank or the like into a collecting trough with a float, and for extracting supernatant water from a sedimentation tank.

[0003]

However, the above-mentioned Japanese Utility Model Publication No. Sho 56-12984 filters the pond water, and cannot remove leaves and the like floating on the pond water surface. Further, even if a device for taking out a supernatant such as a settling tank can remove the supernatant with this device, it cannot separate leaves and the like. Therefore, in order to remove the fallen leaves and the like of the garden pond, a small net is used to scoop up or collect the water collected at the outlet. In particular, the fallen leaves falling in the pond settle down quickly, and it is more difficult to remove the fallen leaves.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the gist of the invention is to immerse the lower end of a screw pump in a pond and to fill the pond with a pond. with connecting lower end of the water conduit, which is suspended from the skimmer which is floated on the surface, the upper end of the screw shaft of the screw pump, connects the water turbine shaft hydraulic turbines installed in the vicinity thereof, above the blades of the water wheel , Having a suction pump to draw in pond water from the lower part of the filter tank and facing the tip of the return pipe of the filtered water of the pond water circulating filter device to return the filtered water from the upper part into the pond. A dust receiving screen is provided below the outlet of the pumping water at the upper end of the screw pump.

[0005]

[Action] device according to the invention is Yes constructed as described above, the return water from the upper portion of the filtration tank, and falls onto the blades of the water wheel to rotate the water wheel, the screw pump coupled to the hydraulic turbine shaft Rotate the screw shaft.

[0006] By the rotation of the screw shaft, the surface water of the pond flowing into the skimmer is pumped by the screw blades. Then, the pumped surface water falls into the garbage receiving screen from the discharge port at the upper end of the screw pump, where floating substances such as leaf fall contained in the surface water are separated,
The separated water returns to the pond.

That is, according to the present invention, in a circulating filtration device for a garden pond or the like, defoliation on the surface of the pond has conventionally been difficult to remove by utilizing the energy of the filtered water that has been returned to the pond by no means. Etc. can be easily removed.

[0008] In particular, the fallen leaves falling into the pond are settled in a short time. Even with such suspended matter, the circulation pump is continuously moved, so the screw pump is also continuously operated. The surface water flows toward the skimmer on the pond water surface and can be collected and removed without sinking. Hereinafter, the present invention will be specifically described with reference to the drawings.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 is a garden pond, and 2 is a skimmer floating on the surface of the pond. A water pipe 2a hanging from the skimmer 2 is connected to a suction port 3a at a lower part of a screw pump 3 provided on one side of the garden pond 1.

The upper end of the screw pump 3 faces the periphery of the pond, and a dust receiving screen 4 is provided below the discharge port 3b of the pumping water. At the upper end of the screw shaft 3c of the screw pump 3, a water wheel shaft 5a of a water wheel 5 provided around the pond is connected by a universal joint. Above the blades 5b of the water turbine 5, the tip of the return pipe 6d of the filtered water from the filtering device 6 of the garden pond 1 faces.

[0011] The filtration apparatus 6, the suction port for sucking pond water at the bottom of the filtration tank 6a of Vertical encapsulating inside filter media
Down flop 6b is is provided with, in each other provided with a take-out tube 6c of filtered water to the top of the filtration tank 6a, return pipe 6d described above in the take-out tube 6c is is connected. That is, the filtration device 6 uses a vertical upward-flow type filtration device, and the pond water sucked from the lower part by the return pipe 6d is filtered while rising in the filter medium, and the filtered water is filtered from the top of the filtration tank 6a. but was due to take-out Unishi,
A water head H is maintained between the outlet pipe 6c and the blade 5b of the water wheel 5.

The apparatus according to the present invention is configured as described above. By operating the filtration device 6, the filtered water of the pond water falls on the blades 5b of the water wheel 5, and the water wheel shaft 5a is rotationally driven. . The screw shaft 3c is driven by the rotation of the water wheel shaft 5a, the surface water of the garden pond 1 collected by the skimmer 2 is pumped, and falls into the dust receiving screen 4 from the discharge port 3b at the upper end of the screw pump 3.

The surface water contains fallen leaves and the like that have fallen into the garden pond 1. These contaminants are separated in the dust receiving screen 4, and the separated water returns to the garden pond 1. Since the circulating filtration device used for this kind of garden pond is normally operated continuously throughout the year, surface water can be constantly collected and automatically separated without leaving any leaves.

[0014]

As is apparent from the above description, the present invention utilizes a recirculating filtration device installed in a garden pond or the like by utilizing the energy of the filtered water that has been returned to the pond unintentionally. This is a solution to the conventional problem, and the profit obtained by using it for maintenance and management of garden ponds and the like automatically in terms of operation is enormous.
