DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fountain device mainly for purifying water floating and mooring in dams, reservoirs, agricultural ponds and the like, and particularly suitable for cold regions.

[0002]

2. Description of the Related Art Many ponds in the suburban area have become increasingly urbanized in the vicinity, so that household wastewater has flowed in and the water quality has deteriorated, leading to eutrophication. A large amount of water is generated, which emits offensive odor and damages the environment. To prevent this, a fountain is installed in the reservoir for purification.

Conventionally, this type of fountain is of a floating type in which the main body of the fountain is floated and moored by a float. In particular, in the case of a cold district specification, a fountain nozzle, piping, a solenoid valve for controlling fountain, etc. are provided near the water surface. In winter, the fountains are submerged in water or pulled up on land to prevent damage due to freezing.

[0004]

However, in the above-mentioned prior art, there is a problem that the fountain device must be submerged in water during winter extreme cold, or must be lifted up and retreated on land. SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and an object of the present invention is to provide a fountain device capable of wintering on a lake or marsh without sinking the device into water or lifting it up to land.

[0005]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, the present invention is characterized in that a dome covering the upper part is provided on the apparatus body floated on the water surface by the float, a fountain nozzle insertion hole is provided in the dome, and a heat insulating material is attached to the inner surface or outer surface of the dome. is there. Further, the present invention is characterized in that a heating means is provided near the water surface in the water in the apparatus main body, and an upper layer water stirring means is provided.

[0006]

According to the present invention, the water surface inside the apparatus main body and the outside air can be shut off by the dome, and the temperature inside the dome can be prevented from lowering by the heat insulating material, and icing can be prevented. Further, the heating of the vicinity of the water surface in the apparatus main body prevents the water temperature from dropping, and furthermore, the upper layer water in the apparatus constantly flows due to the stirring of the water surface, so that freezing is prevented.

The submersible pump (5) is a turbine pump, three of which are mounted on a bottom plate of a small-diameter drum (9) via a mount (19) as shown in FIG.
Each discharge pipe (20)
Is connected via a check valve (21) to a ring-shaped water collecting header (23) mounted on a large-diameter drum bottom plate (8C) by an adjustment stand (22).

The water collecting header (23) is connected to the lower ends of four water pipes (24), (25), (26) and (27), respectively. 27) are control valves (28), (29) and (3) provided above the water surface, respectively.
0), (31) (for example, an electromagnetic valve) are connected, the water pipes (24), (25) are connected to the directly above sprayed water tank (32), and the water pipe (26) is an upper rectifying water distribution ring header.
