DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an energy-saving water purification apparatus according to the present invention will be described with reference to the accompanying drawings, which show only typical ones. The present invention is not limited by the embodiments.

FIG. 1 is a plan view showing a schematic configuration of an energy-saving water purification apparatus 1 according to a first embodiment of the present invention, and FIG. 2 is a schematic sectional view taken along line AA of FIG. FIG. 3 is a cross-sectional view of a main part schematically showing an example of water pumping means operated by a windmill.

In FIG. 1, the water purification apparatus 1 includes a main body 10 having a float portion, water pumping means 20 fixed to the main body 10 and operated by a windmill 21, and a windmill 21 fixed to the main body 10 and facing the wind direction. And a rudder 30 for orienting the water turbine in an orthogonal manner. The whole can be floated on the water surface of a lake or the like, fixed with the anchor 16 so as not to move freely, and the water wheel can always be directed in the wind direction. It is configured as follows. Also, at the edge of the main body 10,
A slope 11 is provided so that a water animal such as a crab or a water bird does not hinder going up and down, and a concave portion 12 capable of storing water and a convex portion not storing water are provided on the surface of the main body 10. A section 13 and a planting section 14 in which aquatic plants, ground plants, and the like can grow naturally are formed.

The main body 10 is made of, for example, a reinforced plastic (F
Each unit made of RP resin is integrally formed by assembling and fixing, and a float portion 17 for floating the energy-saving water purification device 1 on a water surface such as a lake is provided, and a surface of each unit is provided. Are coated with the photocatalyst body 15. The photocatalyst body 15 is a substance in which a photocatalyst represented by titanium dioxide or the like is carried on the surface of a porous carrier such as silica gel, for example, and water pollution is caused by the photocatalytic function of the photocatalyst excited by sunlight or the like. It can decompose not only substances but also harmful substances such as air pollutants,
These can be purified or detoxified. The constituent materials and the overall shape of the main body 10 can be freely changed in design.

Incidentally, the photocatalyst has a photocatalytic activity that is activated by receiving electromagnetic waves having a wavelength of 400 nm or less and decomposes them. For example, TiO ₂ , ZnO, Fe ₂
O ₃ , CdS, CdSe, SrTiO _{3 and the} like can be mentioned, and one or more of these can be used. From the viewpoint of developing excellent photocatalysis, anatase-type TiO ₂ ( It is preferable to use (titanium oxide). Further, a photocatalyst body 15 in which a finely powdered photocatalyst is supported on a porous carrier such as silica gel or activated carbon.
Is preferred because the contact area with the photocatalyst increases and a stronger photocatalytic effect can be obtained.

Next, as shown in FIGS. 3 and 4, the water pumping means 20 comprises a windmill 21 fixed to the main body 10 and a main body 1
0 and a pumping device 22 which operates in conjunction with the rotation of the windmill 21;
3b, and the water guide pipe 23b can freely adjust the pumping direction and the pumping depth.

Next, the pumping device 22 has a belt 22b provided with a plurality of cup-shaped tub bodies 22a on the outside. Each tub body 22a descends in the direction of the water surface in conjunction with the rotation of the windmill 21, enters under the surface of the lake and pumps the lake water, rises while containing the lake water, and rises to the uppermost position. , And the operation of discharging the pumped water to the water discharge channel 24 and spraying water over the entire surface of the main body 10 is repeated.

When the windmill does not rotate, the water environment cannot be improved because the lake water cannot be pumped, of course. However, in this case, the photocatalyst excited by the sun rays emits no air pollutants. It functions to decompose harmful substances such as detoxification.

Since the surface of the main body 10 is provided with a layer of the photocatalyst 15, the surface layer becomes hydrophilic in response to the excitation of the photocatalyst, so that the surface pollutants such as environmental pollutants in the air and water adhere to the surface. Decomposition products can be washed away.

When such operations are repeated, for example, deep water such as lakes and marshes can be moved in the direction of the water surface while being stirred in the water pipe, and can be finally pumped up and sprinkled on the surface of the main body 10. The water environment is improved by decomposing and purifying the water pollutant by using a photocatalyst described later and feeding it back to the lake or the like.

As shown in FIGS. 5 and 6, for example, the lake water discharged from the discharge channel 24 is divided into a plurality of tanks 25a alternately communicating at the lower end thereof.
It may be configured such that water is guided to a storage tank 25 containing activated carbon or the like in 5a. In this case, water pollutants and the like can be adsorbed and removed by the strong adsorption capacity of activated carbon and the like, and then the decomposition and removal action by the photocatalytic function of the photocatalyst acts. Is more preferable because it can be more efficiently decomposed and removed. Even if activated carbon or the like is not stored in each tank 25a, but a layer of the photocatalyst body 15 is formed on the inner surface, water pollutants and the like can be decomposed and purified by the photocatalytic function.

By the way, the “water purification means” described in each of the claims set forth above means a photocatalytic action of a photocatalyst,
It is used as a term indicating a water treatment method utilizing various known water purification methods such as adsorption capacity of activated carbon and the like, and the structure of the water purification means is different due to the difference in the water purification method used. It is self-explanatory.

Next, an energy-saving water purification apparatus 5 according to a second embodiment will be described.

FIG. 7 is a plan view showing a schematic configuration of the water purification device 5, and FIG. 8 is a longitudinal sectional view of a main part.

In the figure, the water purification device 5 has a structure in which the float 17 is not provided, the whole water purification device 5 is semi-fixed with a pier or the like, and the rudder 3 is integrated with the main body 51. A solar cell panel 52 is disposed on the main body 51, and a submersible pump 53 driven by electricity obtained from the solar cell panel 52 pumps, for example, deep water such as lakes and marshes. Although the configuration is different from the water purification device 1 of the first embodiment in that the configuration for discharging is adopted, other configurations are substantially the same as those of the water purification device 1 of the first embodiment except for these points. The water pipe 54 also allows the direction and depth of pumping to be freely adjusted. Note that a configuration in which the entire device 5 is suspended and installed on the water surface may be employed.

According to the water purification apparatus 5 configured as described above, the deep water such as a lake or the like can be pumped up by the submersible pump 52 and then discharged to the water discharge channel 24 at least during the sunshine. The effects are also substantially the same as the effects obtained by the water purification device 1 of the first embodiment, and thus will not be described repeatedly.

[0030]

As described above, according to the water purification apparatus of the present invention, the environmental load on a clear water environment can be suppressed by maximizing and utilizing the natural purification action, and the habitat of wild animals and plants can be reduced. Can be maintained in good condition, the landscape around semi-occlusive water areas such as dam lakes, aquaculture ponds, reservoirs, etc., and the environment around the closed water areas can be beautifully improved, and the overall equipment can be improved in aesthetics. Excellent effects can be obtained.
