Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a purifying float fountain for purifying water from deep ponds, lakes and the like.

[0002]

2. Description of the Related Art Conventionally, in deep ponds, lakes, etc., a water mass with a high water temperature forms a layer in the surface layer near the water surface due to temperature stratification, and water quality such as water-bloom is generated as a water source. There was a problem of decline. For this reason, water is being purified by artificially circulating the water from ponds and lakes. As a purification circulation device of this type, there is a purification float fountain as shown in FIG.

In FIG. 2, a purifying float fountain 1 is arranged on the surface of water such as lake water, a submersible pump 4 having a fountain nozzle 3 is provided inside a casing 2, and a float 5 is provided around the casing 2. Are arranged.

The casing 2 is made of a water-permeable material such as punching metal into a cylindrical shape having an open upper surface, and its upper portion is set to be exposed above the water surface.

A plurality of submersible pumps 4 are arranged at appropriate intervals in the central portion and the peripheral portion of the casing 2 and are fixed to the casing 2, respectively. A vertical discharge pipe 7 is provided. Then, at the upper end of the discharge pipe 7,
The spouting portion 8 provided with one or a plurality of fountain nozzles 3 is provided, and the fountain nozzles 3 are positioned above the water surface in a state where the upper portion of the casing 2 is exposed above the water surface. 9 is a filter attached to the suction port 6.

The float 5 maintains the casing 2 in which the submersible pump 4 is provided in a floating state, and is provided concentrically with the casing 2 on the outer peripheral surface of the upper portion of the casing 2.

The purifying float fountain 1 is placed on the lake water by the buoyancy of the float 5, and the submersible pump 4 is driven. As a result, the lake water in the vicinity of the purification float fountain 1 passes through the water-permeable casing 2 and the suction port 6
Further, it is sucked into the submersible pump 4, reaches the ejection portion 8 through the discharge pipe 7, and is ejected upward from the fountain nozzle 3 at various angles.

At this time, since the float 5 is provided on the outer peripheral surface of the upper part of the casing 2, only the lower part and the lower surface of the casing 2 are open to the lake water, and the lake water near the lower part and the lower surface of the casing 2 is removed. It is sucked by the submersible pump 4 and ejected onto the water surface. As a result, the lake water near the surface of the water descends as a downward flow, a swirling flow is formed near the purification float fountain 1 to circulate the lake water, and the deterioration of the water quality is prevented or the water quality is improved. The lake water jetted upward from the fountain nozzle 3 contains air and falls into the lake, so that the deterioration of the water quality is prevented or the water quality is improved.

Since the cleaning float fountain 1 is supported by the float 5 and is in a floating state, it can be easily moved to any position. Debris in the water is removed when the lake water passes through the casing 2 and by the filter 9, and the submersible pump 4
Clogging is prevented.

[0010]

However, in the above-mentioned conventional purification float fountain, the water is circulated only in the superficial layer, and the circulation range is limited, so that the water quality is not sufficiently purified. There is a problem.

The present invention solves the above problems, and an object of the present invention is to provide a purifying float fountain capable of effectively purifying water quality by expanding the circulation range of water.

[0012]

In order to solve the above problems, the purifying float fountain of the present invention has a casing which is open near the top and has an intake port at the bottom and is arranged near the water surface. A submersible pump which is provided inside and has a suction port opened in the casing and a fountain part located above the water surface; and a conduit whose upper end side is connected to the water intake port at the bottom of the casing and whose lower end opening is opened under an appropriate water depth. ,
And a float supporting the casing and the conduit.

[0013]

When the purifying float fountain having the above structure is placed on the water and floated by the buoyancy of the float and the submersible pump is driven, the water is sucked up from the lower end opening of the conduit at an appropriate depth and flows into the casing. Then, it is sucked from the suction port and ejected from the fountain portion to above the casing. Therefore, the water in the deep layer is sucked up and sprayed on the surface layer, and the water is circulated in a wide range from the surface layer to the deep layer to effectively purify the water. Since the low temperature water in the deep layer is sprayed to lower the temperature of the water in the surface layer, the generation of water-bloom and the like is also suppressed.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A purifying float fountain according to an embodiment of the present invention will be described below with reference to FIG. The cleaning float fountain of this embodiment is almost the same as the conventional one described with reference to FIG.

The purifying float fountain 11 of this embodiment differs from the conventional one in that the casing 12 is made in a shape in which the upper surface is opened by a material having no water permeability and a plurality of water intake ports 13 are provided at the bottom. The conduit 14 is provided by connecting the upper end side to the water intake 13, and the lower end opening 15 of the conduit 14 is provided.
It is the point that is located under the appropriate water depth. The float 5 supports the casing 12 and the conduit 14.

When the purifying float fountain 11 having the above-mentioned structure is arranged by being floated on the lake water by the buoyancy of the float 5, and the submersible pump 4 is driven, the conduit 14 at an appropriate water depth is provided.
The lake water in the deep layer is sucked up from the lower end opening 15, and the sucked lake water flows into the casing 12 through the intake port 13. The lake water that has flowed into the casing 12 is sucked into the main body of the submersible pump 4 from the suction port 6 through the filter 9, reaches the jetting portion 8 through the discharge pipe 7, and reaches various locations above the casing 12 from the fountain nozzle 3. It is jetted at an angle.

At this time, as the lake water in the deep layer is sucked up, the lake water near the water surface becomes a downward flow and descends, and water is circulated in a wide range from the surface layer to the deep layer. As a result, the formation of temperature stratification is prevented and the water quality is effectively purified, and the low temperature water in the deep layer is sprayed, which lowers the temperature of the surface water, which causes the occurrence of water-bloom etc. Is also suppressed. The lake water jetted upward from the fountain nozzle 3 contains air and falls into the lake, which is useful not only for water purification but also for improving the aesthetics of the landscape.

Since the cleaning float fountain 11 is supported by the float 5 and is in a floating state, it can be easily moved to an arbitrary position, for example, a position where a lot of water-bloom and the like are generated.

[0019]

As described above, according to the present invention, the submersible pump provided with the fountain nozzle is provided inside the casing, and the conduit opening to an appropriate depth is connected to the bottom of the casing. It was made to float by a float. As a result, it is possible to suck up the water in the deep layer at an appropriate depth and spray it to the surface layer, and circulate the water in a wide range from the surface layer to the deep layer to effectively purify the water quality, and to generate water-bloom etc. Can also be suppressed. The water ejected upward from the fountain nozzle contains air and falls into the lake, which is useful not only for water purification but also for improving the aesthetics of the landscape.
