[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention relates to a device for purifying the water quality of a retention pond such as a moat, a pond, or a lake. Particularly, bacteria or ammonia that cause pollution are killed or decomposed throughout the retention pond. By doing so, purification is achieved.

[0002]

2. Description of the Related Art In a holding pond such as a moat, a pond, or a lake, there is almost no movement of water, so that bacteria and the like are greatly propagated, the ammonia concentration becomes high, and Ao midoro is generated, resulting in significant pollution. There were social problems. It is widely known that such water pollution can be purified by dissolving a large amount of air in the polluted water.

From such a point of view, air is pumped into a pipe arranged in water using a compressor or a blower, and the air is ejected as bubbles into the water from a large number of small holes provided in the pipe. It is considered that a water wheel is driven by a driving device such as a motor to generate a violent spray, and a large number of bubbles are scratched into the water by the spray. Since the bubbles in the above are too large, they floated to the water surface in a short time due to the buoyancy of the bubbles themselves, and it was not possible to obtain sufficient time for the air to dissolve in the water.

Therefore, a gas-liquid mixing device disclosed in Japanese Patent Publication No. 61-36448 is proposed. This invention has a configuration in which a driving body that rotates at high speed is concentrically arranged in a linear cylindrical outer shell whose upper end opening projects above the water surface.
A high-speed rotation of the driving body causes a vortex flow between the driving body and the outer shell to mix air and water and eject the water into the water. The air can be dissolved in the water in the form of extremely fine bubbles.

[0005]

However, since the above-mentioned conventional invention is fixedly installed at a fixed location on the water, it is possible to remove water from a wide area such as a moat, a pond, or a retention pond such as a lake. There was a problem that could not be purified.

[0006] Further, if air is simply dissolved in water, the amount of oxygen dissolved in the water is increased, thereby more strongly killing microorganisms causing contamination such as bacteria,
There is a problem that pollutants such as ammonia cannot be decomposed and it takes time to purify water.

Therefore, the present invention was devised to solve the above-mentioned problems in the prior art. By mounting an ozone generator and an agitating / mixing device for gas and liquid on the hull, a moat, a pond, The purpose is to achieve the purification of water over a wide area such as a retention pond such as a lake.

[0008]

Means for solving the above technical problem is to have a hull having a propulsion device and an ozone generator mounted on the hull.
It has a guide tube that is installed upright in the opening of the bottom wall of the hull, connects the ozone generator to the upper end of the hull, and has an air intake port. The drive shaft (18) is arranged coaxially in the outer cylinder (14) that projects downward from the wall opening, the upper end is opened into the guide cylinder, and the water inlet is provided at the upper end. It has a gas-liquid mixing device that stirs and mixes water and gas with the outer cylinder by being rotated and jets the mixture into the water from the lower end opening of the outer cylinder.

For steering the hull, ultrasonic sensors for detecting obstacles are preferably arranged at the front end and right and left of the front end of the hull, and automatically controlled by a detection signal of the ultrasonic sensor.

In addition, the rear end of the hull also serves as a float at the front end opening for collecting suspended matter such as dead aquatic plants on the water surface.
It is good to tie up a bag body provided with a rounded circular reinforcing frame .

[0011]

[Operation] When the hull is floated on the water, water has invaded the guide cylinder with the bottom wall opening at the lower end opening up to a certain water level, and is opened at the upper end of the outer cylinder of the gas-liquid mixing device. The water inlet is located slightly below the water level in the guide cylinder. Further, water penetrates to the same water level between the outer cylinder of the gas-liquid mixing device and the drive shaft.

The ozone generator and the gas-liquid mixing device are driven while the hull is traveling at a low speed by the propulsion device. By driving the gas-liquid mixing device, water and gas between the outer cylinder and the drive shaft are agitated and mixed, and are vigorously ejected downward from the lower end opening of the outer cylinder, and at the same time from the water inlet of the outer cylinder to the guide cylinder. Water continuously flows between the outer cylinder and the drive shaft through the outer cylinder, and the mixed gas of ozone and air generated in the ozone generator from the upper end opening and the water inlet of the outer cylinder becomes the outer cylinder. And the drive shaft are continuously sucked.

Since the bubbles in the gas-liquid mixture ejected from the gas-liquid mixing device into water are extremely small, the residence time in water is long, and therefore ozone and air are strongly dissolved in water. The dissolution of ozone and air into water is achieved in a wide range because the hull is traveling at low speed.

When gas is dissolved in water, not only air but also ozone is dissolved.
Bacteria and microorganisms are more effectively killed, pollutants such as ammonia are efficiently decomposed, and water purification is strongly achieved.

When an ultrasonic sensor is attached to the hull and the ultrasonic sensor detects an obstacle in the navigation of the hull to automatically control the steering of the hull, the hull can be operated unmanned, It is especially effective for purifying water in a wide lake.

If the bag is anchored to the rear end of the hull, it is possible to collect the suspended matter on the water surface, such as dead aquatic plants, as garbage along with the navigation of the hull for water purification. In this case, since the hull sailing good at a low speed, causing trouble in sailing hull to anchor the bag body rather than also the bag
The opening of the body is a reinforced frame that doubles as a float to keep it open.
Since it is located on the surface of the water as it is
The collection can be achieved reliably and satisfactorily, and the bag body becomes a rope on the hull.
More simply tethered, so its handling
It's easy.
