The control block 40 is coupled to the upper end of the housing 20 via the floating body 30 so that the control block 40, the floating body 30, and the upper end of the housing 20 may be fixed to each other.

The control block 40 has a power supply for lighting the steering motor 71, the ultraviolet sterilization lamp 50, and the operation of the steering motor 71, the circulation pump 60, the ultraviolet sterilization lamp 50, etc. A controller for controlling is installed.

The ultraviolet sterilization lamp 50 extends downward from the control block 40 and extends from the inside of the housing 20 to the upper side of the space 16 in which the circulation pump 60 is installed.

Since the portion of the UV sterilization lamp 50 where water is substantially sterilized is an area until water is sucked up and discharged from the inside of the housing 20, the UV sterilizing lamp 50 is a suction port 22 in the interior of the housing 20. In the area between) and the outlet 23, part or all of it should be arranged.

The UV sterilization lamp 50 is preferably installed so that a pair extends side by side with each other, and the upper holder 51 supporting the upper end of the UV sterilization lamp 50 is installed in the control block 40, and the circulation pump 60 A lower holder 52 is installed and supported on the upper surface of the space 16 where is installed.

In addition, the intermediate portion of the UV sterilization lamp 50 is installed to pass through the support hole 83 of the photocatalyst casing 80 so that the intermediate portion of the UV sterilization lamp 50 is supported by the photocatalyst casing 80 as well. .

On the other hand, the circulation pump 60 is installed at the lower end of the housing 20 to suck water from the inlet 22 to the inside and rise around the UV sterilization lamp 50 to generate a flow discharged to the outlet 23 Let it.

In the space 16 in which the circulation pump 60 is installed, the upper surface is divided by a diaphragm 17, and the lower holder 52 is installed on the upper surface of the diaphragm 17, and the diaphragm 17 is a circulation pump 60. It may be a plate body, a porous plate, or a mesh plate having a through hole formed in the middle portion so that the water jetting out to the upper side passes.

Meanwhile, a plurality of photocatalysts 85 are disposed around the UV sterilization lamp 50 in the area between the inlet 22 and the outlet 23 of the housing 20.

The photocatalyst material 85 is disposed in a state accommodated in the photocatalyst material casing 80, and the photocatalyst material casing 80 forms a circular cylindrical shape and is fixed to the inner circumferential surface of the housing 20. have.

3 and 4, in the photocatalyst casing 80, a support hole 83 penetrating up and down is formed on the upper surface 81 and the lower surface 82, so that the ultraviolet sterilization lamp 50 passes through the inside and is installed. The upper surface 81 and the lower surface 82 form a network or a porous surface so that rising water can pass in the vertical direction.

The photocatalyst 85 is manufactured in the form of a plurality of balls or grains, and is formed to include TiO2 on the surface.

When TiO2 is irradiated with ultraviolet rays, strong sterilization can be achieved through strong oxidation and reduction by AOP reaction.

On the other hand, in this embodiment, a steering member 72 whose rotation angle is adjusted so that the floating sterilization device 10 can autonomously move within the water storage tank is installed.

3 and 5, the steering member 72 is located at a position in which the discharge port 23 is formed inside the housing 20 so that water rising from the lower side collides and discharges to the discharge port 23 in the lateral direction. To induce.

At this time, as shown in (a) and (b) of Fig. 5, the water hits the steering member 72 and receives a force in the opposite direction to the discharge direction, so that the housing 20 in which the steering member 72 is installed moves. This becomes possible.

The steering member 72 has a steering surface 72a that converts the flow in the lateral direction by hitting water rising from the circulation pump 60, and is connected to the steering motor 71 installed in the control block 40 to change the direction. This is done.

As the steering member 72 rotates at a predetermined angle by the steering motor 71, the direction in which water flows and discharges is determined in the lateral direction, and thus the direction in which the housing 20 moves while floating on the water surface is determined.

That is, the rotation angle is adjusted so that the steering surface 72a of the steering member 72 faces in a selected direction among the circumference of the housing 20 by the rotation of the steering motor 71, and accordingly, the moving direction of the housing 20 Is controlled.

In a configuration in which an external control panel panel 15 is installed so that the administrator can set the condition and operation state, the controller of the control block 40 receives the setting signal from the control panel 15 and transmits it to each device. A configuration including a role and an external control panel 15 becomes the controller of this embodiment.

Meanwhile, in the floating sterilization device 10 of the present invention, a flow and light guide plate 90 may be installed on the upper side of the photocatalyst material casing 80.

The flow and light guide plate 90 induces the water flow rising to the steering member 72 to be concentrated to facilitate the direction change and movement of the floating sterilization device 10, and the ultraviolet rays irradiated from the ultraviolet sterilization lamp 50 It is to increase the reaction action with the photocatalyst and further improve the sterilization power by concentrating the photocatalyst 85.

Referring to Figure 7, the flow and light guide plate 90 is located between the steering member 72 and the photocatalytic material casing 80, has a hat shape in which the upper outlet 91 is formed, according to the shape The inner surface has an annular tapered surface that narrows as it goes upward.

A reflective surface 92 capable of reflecting ultraviolet rays, like a mirror, is formed on the tapered surface.

Accordingly, the flow and light guide plate 90 collects and raises the rising water through the narrowed upper outlet 91 so that water is concentrated and supplied toward the steering member 72 located in the center of the housing 20. In addition, this makes it possible to more smoothly change the direction and move of the floating sterilizer 10 even in a situation where the output of the circulation pump 60 is weak.

In addition, since the tapered surface is formed as the reflective surface 92, the ultraviolet rays irradiated from the ultraviolet sterilization lamp 50 are reflected and further irradiated toward the photocatalyst material 85 accommodated in the photocatalyst casing 80, so that the photocatalyst and The reaction action of can be improved and the sterilizing power can be further improved.

Serrated teeth 93 are formed all over the circumference along the circumference of the upper exit 91, and the serrated teeth 93 can alleviate the inability to concentrate on the steering member 72 due to disturbance of the rising water flow. have.

That is, in the absence of the serrated teeth 93, the ascending water flow increases the speed in a narrowed cross-sectional area, and causes a vortex turbulence outside the upper exit 91, that is, around the upper exit 91, which is the upper circumference of the hatchet shape. Although it prevents the ascending water flow from being concentrated on the steering member 72, the eddy turbulence is weakened due to the serrated teeth 93, and it may be more smooth for the water flow to flow to the steering member 72.

Although the preferred embodiments of the present invention have been described above, the above embodiments are only one embodiment within the scope of the technical idea of the present invention, and for those skilled in the art, within the technical scope of the present invention. Of course, other modified implementations are possible.
