In this embodiment, a water channel 11 is provided on the outer peripheral side of the float 1.

[0015] FIG. 2(a) is a plan view of the waterway 11, and FIG. 2(b) is a plan view of the waterway 11. It is a partial cross-sectional side view taken along I-II line. In the figure, the waterway 11 includes a plurality of (4 in the figure) outflow holes 12 are drilled at the bottom, and during operation, as shown in Figure 1, , is discharged from the impeller 3 through the discharge channel as shown by arrow B, and is received into the waterway 11. The collected water C flows out from the hole 12 into the pond.

[0016] Furthermore, inside the waterway 11, there is a filtration device 13 such as a filter, and a filtration device 13 such as a filter. For example, an adsorbent 14 such as activated carbon is installed. One of the filter devices 13 For example, the roughness of the filter lattice, or the size of the mesh, and one of the adsorbents 14. The amount of activated carbon installed will depend on the degree of need and demand for improving and preserving the quality of pond water. It can be adjusted as appropriate.

[0017] The flow of pond water is as follows. That is, the suction water A flows through the suction bell 7 and the suction pipe. 5, from the discharge channel formed by the upper surface of the float 1 and the deflector 6. , is discharged as shown by arrow B, is aerated when received into waterway 11, and is discharged as shown in arrow C. will be collected in After that, a filtration device 13, an adsorbent 14, etc. provided in the waterway 11, etc. , flows out from the water hole 12 as shown by arrow D, and forms the surface water layer along the pond water surface L. Flow E is formed to aerate the entire pond, remove suspended matter, and reduce chemicals. The pond water circulates and spreads throughout the pond.

[0018] Figure 3 shows an embodiment in which the first idea and the second idea of the present invention are combined. This is a cross-sectional side view of the main parts, and the same reference numerals as in Fig. 1 are not the same. This figure shows similar parts, and points different from the previous embodiment (FIG. 1) will be explained.

[0019] In this embodiment, the flow at the bottom of the water channel 11 provided around the entire outer circumference of the float 1 is A discharge pipe 15 is attached to the exit hole 12, and the discharge pipe 15 is connected to the water depth of the installation pond. It is formed to have approximately the same length as the suction pipes 5, 5a which are extended correspondingly. Up The fact that a filtration device 13, an adsorbent 14, etc. are installed in the dielectric channel 11 is due to the previous implementation. There is no difference from the example (Figure 1).

[0020] According to this embodiment, the suction pipes 5, 5a and the drain pipe 15 are arranged according to the water depth of the installed pond. By adjusting the installation length of the pond, you can eliminate the need for aeration and agitation of the entire pond. , can aerate and agitate the deep water layer and bottom water layer, and at the same time remove suspended solids. It is possible to remove and reduce chemicals and chemicals. Therefore, the water temperature corresponds to the water depth. Since the distribution is maintained and the biological system is not destroyed, it can be used as agricultural water or water for aquaculture. However, it is still usable.

[0021] In addition, if it is necessary to aerate and stir the entire installed pond, please use the method shown in Figure 4. In this case, only the suction pipes 5 and 5a are extended to correspond to the water depth, and the drain pipe 15 is not installed. It can also be configured.

[0022] Figures 5(a) and (b) to 8(a) and (b) show four different usage conditions. A diagram showing an example of the flow pattern (action diagram) and distribution of water temperature and dissolved oxygen It is.

[0023] In FIG. 5(a), the water depth is shallow and the suction pipe 5 is extended, as in the embodiment shown in FIG. This is a flow pattern when neither the pipe 5a nor the drain pipe 15 is attached. In this case, Ikeuchi Suspended matter and chemicals are removed or reduced throughout, and sufficient aeration and agitation are performed. Therefore, the distribution of water temperature and dissolved oxygen becomes uniform throughout the layer, as shown by the solid line in FIG. Note that the dotted line indicates the case where the floating aerator is not installed or operated. This figure shows the distribution of water temperature and dissolved oxygen with respect to water depth (the same applies below).

[0024] Figure 6(a) shows a floating aerator with the same configuration as Figure 5(a) at different water depths. This is the flow pattern when installed in a deep pond. In this case, the deep water layer and bottom water layer The water temperature distribution and dissolved oxygen distribution in the deep water layer and bottom water are different from those in Figure 5(a). The layer remains in its original state and is not improved.

[0025] In FIG. 7(a), as in the embodiment shown in FIG. 3, the water depth is deep and the suction pipes 5, 5a and a flow pattern when the drain pipe 15 is extended according to the water depth. this place In this case, only the deep water layer and bottom water layer below from the lower end of the suction bell 7 and drain pipe 15 are aerated and At the same time as stirring, suspended matter and chemicals are removed or reduced, as shown by the solid line in Figure (b). As shown, the distribution of water temperature and dissolved oxygen becomes uniform only during this period.

[0026] In Fig. 8(a), the water depth is deep, and only the suction pipes 5 and 5a are extended corresponding to the water depth, and the water is drained. This is the flow pattern when pipe 15 is not attached. In this case, the entire installed pond is aerated. The water is stirred and the water temperature and dissolved oxygen distribution become uniform throughout the layer.

[0027] In each of the above embodiments, the structure has four outflow holes 12 at the bottom of the water channel 11. However, the number of holes 12 is appropriately selected depending on the amount of outflow. In addition, the collection water channel provided on the outer circumferential side of float 1 is installed all around the outer circumferential side of the float. Although we have explained the integrally installed structure, it is important to remove floating objects and chemicals, and to Channel 11 can be removed for applications where aeration is not required and only aeration and agitation are required. Can be installed as possible.

[0028]

[Effect of the idea]

As explained above, according to the first invention of the present invention, on the outer circumferential side of the float, It is possible to form a waterway and install a filtration device, adsorbent, etc. inside the waterway. By creating a structure that allows pond water to be aerated and agitated, floating matter and pesticides can be removed at the same time. It is possible to remove and reduce chemicals such as herbicides, nitrogen, and phosphorus.
