[Problems to be Solved by the Invention] This fountain effect device includes a drive pump for discharging water flowing into the overflow weir,
A drive pump for the fountain device is provided, but since these are independently configured, the system becomes complicated and causes an increase in cost. The present invention has been made to solve the above-mentioned problem, and an object thereof is to simplify the system of the entire fountain effect device and to provide an inexpensive effect device.

[0004]

According to a first aspect of the present invention, a bottomed overflow weir is provided for water treatment ponds, lakes, marshes, rivers, and the like. The water that has flowed into the pump is drained, and
A fountain effect device in which a fountain device by a fountain tower is installed in the overflow weir, wherein a drive pump of the fountain device and a drive pump for discharging water from inside the overflow weir can be at least coaxially driven. It is characterized by having a relationship.
According to the second aspect of the present invention, in addition to the drive pump for the fountain device and the drive pump for discharging water from the overflow weir, a blower provided in the fountain tower can be coaxially driven.
The invention according to claim 3 is a drive pump for discharging water in a lower layer from the overflow weir, in addition to a drive pump for the fountain device, a drive pump for discharging water from the overflow weir, and a blower provided in the fountain tower. Are all in a relationship that allows coaxial driving.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. 1 and 2 show an embodiment of the present invention. In this embodiment, reference numeral 1 denotes a final sedimentation basin formed in a sewage or water treatment facility, and a water surface 2 is set. Reference numeral 3 denotes an overflow weir having a circular bottomed shape, and a V notch 3a is provided at an upper end thereof.

An outer disk 4 is attached to the outer periphery of the overflow weir 3 so as to be below the water surface 2. The outer disk 4 may be provided with a float. Below the overflow weir 3, the level of the middle water is set, and a bottomed partition 5 for partitioning from the overflow weir 3 is provided. These are supported by supporting means (not shown), but may be configured in a balanced manner by the float and the partitioning machine 5 serving as a weight.

The lower side of the partition 5 is a lower layer 6. A conical fountain tower 7 is provided in the overflow weir 3, and a fountain nozzle 8 is provided at an inner apex of the fountain tower 7. Water is supplied to the fountain nozzle 8 by a fountain drive pump 10 provided in the lower layer 6. An upper pump 11 for discharging scum water is provided in the overflow weir 3, and a lower pump 12 for discharging middle water is provided in the partitioning plate 5, respectively. The scum water and the middle water that flowed in are discharged.

A blower 13 is provided in the fountain tower 7, and air from the blower 13 is blown out from an air blowout pipe 14 provided in a lower layer, so that a water purifying action can be achieved. .

By the way, each of the above pumps 10, 11,
The motors 12 and 13 are coaxially linked by a common drive shaft 16 by a motor 15 provided in the fountain tower 7. The water injected from the fountain device 9 has a V notch 3a.
… So that algae do not develop or grow. Further, the overflow weir 3 is formed of a paint for preventing algae generation or a copper plate.

This invention is a fountain effect device as described above, characterized in that the drive pump of the fountain device and the drive pump for discharging water from the overflow weir are at least coaxially drivable. Therefore, the system of the entire fountain effect device can be simplified, and an inexpensive effect device can be provided. In addition to the drive pump for the fountain device and the drive pump for discharging water from the overflow weir, the blower provided in the fountain tower can be coaxially driven. A pump, a drive pump for discharging water from the overflow weir, a blower provided in the fountain tower, and a drive pump for discharging water below the overflow weir are all coaxially drivable. Then, the cost can be further reduced.
