Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses the energy of waves to collect suspended debris, improve the quality of oxygen-deficient seawater and lake water, and distribute aerobic purified water into the sea or lake. The present invention relates to a floating water quality improvement device for supplying. Further, the device of the present invention can be used as a dock or a fish cage while exhibiting the effect of water purification.

[0002]

2. Description of the Related Art Heretofore, in order to collect garbage on a beach or the like, garbage has been collected by a net using a boat. As a method of improving the water quality of poor oxygen, aeration using an air pump has been generally performed. However, those methods consume a lot of fuel and electricity,
It is not economical.

One method that does not require replenishment of fuel or the like is to use wave power. However, the idea of using wave power that has been conceived so far is mainly to improve fixed structures such as breakwaters and seawalls.

[0004]

The above-mentioned fixed structure is usually effective only in places where waves are strong, and the range of the effect is limited to places near breakwaters and the like. In addition, it is difficult to follow the water level fluctuation due to the lake tide, so it may be effective at one water level but not valid at another level.
There is a problem.

The present invention has been made in view of the above-mentioned circumstances, and in the improvement of water quality using wave power, a place where a fixed structure is not good, where there is a lake, or where a wave is relatively quiet. Attempting to provide a floating body-type water quality improvement device that can naturally collect and aerate airborne garbage and aerate aerobic water generated by aeration even in the middle and bottom layers of poor oxygen. It is.

[0006]

The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. 4, a groove 6 is provided on the upper surface of the generally trapezoidal floating body 1, and the upper end of the floating body 1 is open to the upper surface of the floating body 1 and connected to the groove 6, and the lower end has a required water depth position. A tubular body 5 having an opening is vertically provided.

A second aspect of the present invention is the apparatus according to the second aspect, wherein a bottom plate 7 having perforations 8, 8 is provided at a lower end portion of the cylindrical body 5, and a filter medium 9 is set thereon to a required thickness. It is characterized by having done.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. The apparatus of the present invention is composed of a floating body and a cylindrical body. FIGS. 1 and 2 show a basic embodiment, and FIGS. 3 to 6 show other embodiments.

1 and 2, reference numeral 1 denotes a floating body,
The lower surface 3 is a flat surface, and the outer surface 4 is an upwardly inclined surface, and is formed in a substantially hollow trapezoid. At a required position of the floating body 1, for example, at a central portion, a vertically long cylindrical body 5 is provided so as to penetrate the upper part of the floating body 1 vertically and open on the upper surface of the floating body 1. Upper surface 2
Are provided with a plurality of grooves 6, 6 each having an inner end connected to the upper end of the cylindrical body 5 so that the inner end connected to the cylindrical body 5 becomes deeper. The lower end of the cylinder 5 has
A bottom plate 7 having a large number of holes 8, 8 is provided. On the bottom plate 7, a filter medium 9 such as gravel is filled and installed over a required thickness.

The angle between the outer surface of the floating body 1 and the horizontal plane is preferably such that the water can easily run up the slope even in the case of a small wave, and the common sense is, for example, about 5 to 75 degrees. Is preferable. However, where the waves are small,
In order to collect the overtopping water efficiently, the inclined surface may be constituted by a plurality of different gradients. In addition, the length of the cylindrical body 5 is appropriately selected so that the lower end thereof reaches the vicinity of the middle or bottom layer of the water.

Further, the floating body 1 is provided with a means for retaining the floating body 1 at the water bottom with a wire 10 or the like. Further, for the purpose of, for example, reducing the movement of the floating body 1, a float can be appropriately reserved separately at a key point of the floating body 1.

In the above device, since the outer surface 4 of the floating body 1 is inclined, water can easily run up the inclined surface even in the case of a small wave, and the water flows over the upper surface 2. It falls into the grooves 6, 6 and flows into the cylinder 5. At that time, garbage floating on the water surface also flows in and is captured together with the water. Further, the water is aerated at the time of overflow and flows into the cylinder 5 in a state where oxygen is stored.

In this way, aerobic water is supplied to the cylinder 5 one after another, so that the aerobic water stays in the cylinder 5, and through the holes 8, 8 in the bottom plate 7 of the cylinder 5, Will be discharged into the lake water. In this case, since the lower end of the cylinder 5 is located at the middle and bottom layers of poor oxygen, aerobic water is supplied to the poor oxygen layer to improve the water quality.

In addition, dust and the like that have flowed into the cylindrical body 5 and collected can be easily removed and disposed of as appropriate, and suspended substances and the like in water are captured by the filter medium 9. . Therefore, the water discharged from the lower end of the cylindrical body 1 has little dust or suspended matter, and the transparency of seawater or lake water can be improved.

The device of the present invention is not limited to the above-described basic embodiment, but has various concrete configurations.
Can be added. For example, the plane shape of the floating body 1 is square, rectangle, circle, ellipse, star, cross,
Alternatively, a boomerang shape as shown in FIG.
Various shapes such as skewers as shown in FIG. 4 are possible,
The planar shape can be appropriately selected from conditions such as the wave characteristics at the installation location, the terrain, and the multipurpose use of the device of the present invention.

Further, the shape and number of the grooves 6 can be selected as appropriate, and the number of the vertically extending cylindrical bodies 5 can be plural, for example, as shown in FIG. In addition, the filter medium to be used may be sand, lime-containing minerals, earthenware particles, cotton or cloth made of natural or synthetic fibers, in addition to gravel.

The apparatus of the present invention is intended for collecting dust and the like and improving the quality of water. However, the apparatus can be used for other purposes. For example, as shown in FIG. 5, if a platform 11 is attached to the upper surface of the floating body 1, it can be used as a yacht holding facility. In addition, if living things such as fish are kept in the cylinder 5, floating dust and plankton can be removed by the action of the organism, and the cylinder 5 can be used as a living cage.

[0018]

As described above, according to the present invention,
Waves can be used to collect floating debris even in tidal places and relatively quiet places such as harbors, bays and lakes.
Oxygen-containing water can be sent through the cylinder to the middle and bottom layers of poorly oxygenated water, thereby improving the quality of seawater and lake water.

In addition, the suspended matter in the water can be removed by the filter medium provided in the cylindrical body, and a favorable environment can be provided for the animal in the water. Furthermore, the device of the present invention can be used as a versatile facility such as a place for leisure or recreation, or used as a living cage.
