Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fountain device especially suitable for cold regions, which is mainly used for clean water levitated and moored in dams, reservoirs, agricultural ponds and the like.

[0002]

2. Description of the Related Art Many of the ponds in the suburbs near the city have become eutrophication due to poor water quality due to the inflow of domestic miscellaneous drainage due to the progress of urbanization in the vicinity. A large amount of water is generated, which gives off a bad odor and damages the environment. As a countermeasure against this, a fountain device for purification is installed in the reservoir.

Conventionally, this type of fountain device is of a floating type in which the body of the device is floated and moored by a float. Especially, in the case of a cold region type, a fountain nozzle, a pipe, a solenoid valve for controlling the fountain, etc. are arranged near the water surface. In winter, the fountain is submerged or pulled up on land to prevent damage from freezing.

[0004]

However, the above-mentioned conventional technique has a problem that the fountain device must be submerged in water or pulled up on land to be evacuated during extremely cold winter. The present invention has been made by paying attention to the above situation, and an object of the present invention is to provide a fountain device capable of overwintering on a lake without submerging the device in water or pulling it up to the land.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention is characterized in that the device main body floated to the water surface by the float is provided with a dome for covering the upper part, the fountain nozzle insertion hole is provided in the dome, and the heat insulating material is attached to the inner surface or the 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 body, and an upper layer water stirring means is provided.

[0006]

According to the present invention, the water surface in the main body of the apparatus and the outside air can be shielded by the dome, and further, the heat insulating material prevents the temperature inside the dome from lowering and prevents the freezing. Further, heating near the water surface in the apparatus main body prevents a decrease in the water temperature, and furthermore, by stirring the water surface, the upper layer water in the apparatus is constantly flowing, so that freezing is prevented.
