Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for purifying water by purifying plants such as lakes, marshes, dams, etc. by irradiating sunlight to portions where sunlight does not reach, and supplying oxygen by its carbon assimilation. It is intended.

[0002]

2. Description of the Related Art Heretofore, as a water purifying apparatus and a purifying method of this kind, a method of agitating or circulating water with a large-sized pump to aerate the water, and a method of sucking up water to separate and remove water moss and the like are known. ing.

[0003]

However, in the prior art as described above, a pump and a filtration device are required to move water and to filter and separate blue-green algae, and the initial cost and the running cost are high. .

[0004]

The present invention has the greatest feature of using infinite solar energy as energy for purification, and its gist is to float on the surface of water such as lakes and marshes. The float is equipped with a condenser lens on the upper end and an optical fiber holding cylinder with a diffuser lens on the lower end, and the upper end of the focusing of the optical fiber housed in the holding cylinder is the focal point of the condensing lens. The lower end is exposed to the light source part of the diffuser lens.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION That is, the sunlight collected by a condenser lens illuminates the upper end of a converging optical fiber, and the light sent by the optical fiber is emitted by a light source portion of a diffuser lens.
It is designed to illuminate deep water by dispersing it with a diffusing lens. And by the sunlight sent in this way,
It irradiates deep water to vegetate plants and the like in the layer portion to cause carbonic acid assimilation. The plant absorbs rich nutrients and at the same time releases oxygen to purify surrounding water.

As is clear from the above description, if the device is installed, the operation for purification thereafter uses infinite solar energy, so that driving energy is not required,
As the operating cost, only the maintenance and management cost for the condenser lens, the diffuser lens, etc. is sufficient. The float on which the light collecting and dispersing device is mounted may be fixed or movable. Hereinafter, the present invention will be specifically described with reference to the drawings.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a state in which a purifying apparatus according to the present invention is installed on a water surface H, in which reference numeral 1 is a float,
Reference numeral 2 is a holding cylinder that houses a light collecting device such as an optical fiber.
Is a tether wire, and E is a water bottom.

Next, the light collecting device will be described with reference to FIG. A condenser lens 4 made of a convex lens is attached to the upper end of the holding barrel 2, and a diffusing lens 5 made of a concave lens is attached to the lower end of the holding barrel 2. Also, the holding cylinder 2
A focused optical fiber 6 is housed therein, and the upper end surface of the optical fiber 6 faces the focal point F portion of the condenser lens 4 and the lower end surface faces the light source L portion of the diffuser lens 5.

The condenser lens 4 and the diffuser lens 5 are
Transparent protective cover 7a and protective cover 7b, respectively
And is attached to the holding cylinder 2. Then, as shown in FIG. 3, the protective cover 7a of the condenser lens 4 and the protective cover 7b of the diffuser lens 5 have wipers 8a and 8a, respectively.
b is attached for cleaning. Code 9
Is a motor for driving the wiper, and this motor is driven by the solar cell 10 attached to the upper part of the float 1.

The apparatus according to the present invention is constructed as described above, and the sunlight that has passed through the condenser lens 4 is collected at the focal point F thereof, and is placed on the optical fiber 6 having its upper end facing the focal point portion. Irradiate the end face. Then, the irradiation light passes through the optical fiber 6 and is emitted by the light source L portion of the light diffusing lens 5 and diffused by the light diffusing lens 5 to illuminate a deep water layer such as lake water.

That is, natural sunlight is condensed by the condenser lens 4,
It can be sent to the deep layer by the optical fiber 6 and the diffusing lens 5, and promotes the growth and development of aquatic plants and phytoplankton that could not grow due to lack of light quantity, and this growth has contributed to the rich nutrients that were conventionally retained in the deep layer. In addition to absorbing and decomposing water, it is possible to purify the water quality by supplying oxygen into the water by carbonic acid assimilation by growth.

Further, in the above-mentioned purifying action, in the present invention, since infinite solar energy is used as the energy to be used, the driving energy for the pump and the running cost for the chemicals are unnecessary, and the lens cleaning and the like are slightly required. It requires maintenance costs. In addition, since it is purified by natural sunlight and naturally occurring plants, phytoplankton, etc., no secondary pollution occurs at all.

[0013]

As described above, the purification apparatus according to the present invention utilizes infinite solar energy for purification. Therefore, if the apparatus is installed, only maintenance and management of the apparatus is required as a running cost. Since it is natural energy called light, it can be said that there is no secondary pollution as compared with conventional devices and methods, and it is extremely useful in water purification.
