Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterfall device installed in a park, garden, or the like.

In particular, it relates to a waterfall device installed integrally with a pond installed in a park or the like. In recent years, as the water situation has worsened, it has not been possible to frequently replace the water in ponds, and there is also a limit to the amount of water that can be supplied to ponds.

Furthermore, it is almost impossible to supply water to a pond in a waterfall. In particular, ponds in urban areas are in a state where there is little water coming in and out, and even the habitat of fish is at risk, and they are gradually becoming undesirable as facilities for entertaining people strolling through parks and gardens. In view of the above-mentioned circumstances, the present invention has been developed to provide a waterfall device that can purify the water of ponds installed in parks and gardens, can also supply oxygen to the water, and can soothe the hearts of viewers. It is intended for the purpose of providing. Hereinafter, the present invention will be explained according to illustrated embodiments.

FIG. 1 is a longitudinal sectional view of the present invention, and FIG. 2 is a plan view, where 1 is the other.

Some parts of the shore of this pond are higher than others,
Waterfall 2 is formed by stacking rocks and rock fragments. On the back side of the waterfall 2, that is, on the opposite side from the pond 1, a plurality of upward flow lachrymal drainage devices 3 are integrally installed as shown. The upflow type filtration device is a known one, in which raw water supplied from a raw water supply pipe 4 is supplied to the lower part of the filtration tank main body 5, and is passed through a filtration layer 6 consisting of a support layer and a droplet. The water is passed in an upward direction to obtain the filtration treated water from above the filtration tank main body 5. In this embodiment, the furnace filtration tank main body 5 is designed so that the filtration treated water can be used as waterfall water.
The upper end is slightly higher than the upper end of waterfall 2. There is a trough 7 between the furnace filtration tank body 5 and the tank, and the trough 7 once receives the furnace filtration water and distributes it uniformly over the upper surface of the waterfall 2. Of course, this trough T is the furnace tank main body 5.
It is also possible to omit the cassava wall on the waterfall side by making it lower than the other cassava walls. In addition, in the figure, 8 is a backwash water discharge trough, and 9 is a valve provided in the backwash water discharge pipe and the Ichikawa Mako pipe. Further, P is a pump for supplying other water to the upflow type furnace casing straight 3, and is provided in the raw water supply pipe 4 described above.
Furthermore, on the suction side of the pump P of this raw water supply pipe 4,
A strainer 11 is provided. In the present invention configured as described above, coarse solids such as leaves are separated from pond water using the strainer 11, and the pump P supplies the water to the upflow filtering device 3.

Water may be taken from another source, such as overflow water from a pond as shown, but it may also be taken from the bottom of the pond. While the pond water sent to the furnace filtration device 3 flows upward through the packed bed 6, suspended solids (SS) contained therein are removed and becomes clear furnace filtration treated water. It flows into the trough 7 from above the tank body.

The water uniformly spread over the waterfall 2 from the trough 7 is
Flow down the waterfall and return to the pond. When water flows down this waterfall,
Contact with air allows sufficient oxygen to be incorporated into the water. Therefore, fish and other creatures can live safely in the pond. The upflow type filtration device 3 used in the present invention can be cleaned in the same manner as a normal filtration device.

That is, when the furnace overload resistance has reached a certain level, or when the furnace overflow process has been performed for a certain period of time, the valve 10 of the overflow equipment is opened, and at the same time, the water flow linear velocity is several times higher than that during the furnace overflow process. Pass water. As a result, the furnace material expands, and the SS attached to the furnace material is peeled off from the furnace wall and removed to the outside of the furnace filtration device. Once this is completed, adjust the water flow linear velocity to the normal furnace passing process.
After the cleaning water is discharged from the discharge pipe 9 for a certain period of time, the valve 10 is closed and the process moves to the furnace passing process. In addition, the above-mentioned cleaning process includes
As with normal upflow filtration equipment, it is also possible to add air backwashing or gas-liquid mixed backwashing to further enhance the cleaning effect.

Also, it is possible to use only one filtration device instead of multiple ones, but in the case of multiple filtration devices, the water supply to the waterfall can be stopped by making a difference in the cleaning process time of each filtration device. It's convenient because there aren't any. As described above, the present invention is capable of keeping pond water clear by using an upflow filtration device, and also supplies water to the pond by using the clear water for a waterfall. As a result, people playing around the pond can feel as if the clear water is gushing out endlessly.
