Description

[Detailed description of the device]

[0001]

[Industrial applications]

 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, and achieves purification by killing or decomposing bacteria or ammonia that cause pollution, all over the retention pond. To do.

[0002]

[Prior Art]

 Since there is almost no movement of water in the moats, ponds, lakes, etc. It was happening. 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, it is possible to use a compressor or a blower to pump air into a pipe arranged in water, and to eject the air as bubbles into the water from a large number of small holes provided in the pipe. It is conceivable that a water turbine can be driven by a drive device such as a motor on the water surface to generate a violent splash of water, and a large number of air bubbles can be scratched into the water by the splash of water. The bubbles in the water were so large that 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. The present 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. Is generated, and the air and water are mixed and ejected into the water, and 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 an entire 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, simply dissolving air in water increases the amount of oxygen dissolved in water, thereby more powerfully killing microorganisms that cause pollution such as bacteria and decomposing contaminants such as ammonia. There was a problem that it could not be done and it took time to purify the water.

Therefore, the present invention was devised to solve the above-mentioned problems in the prior art, and by installing an ozone generator and an agitating / mixing device of gas and liquid in the hull, a moat or a pond can be provided. The objective 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 Problems]

 Means for solving the above technical problem are as follows: a hull having a propulsion device, an ozone generator mounted on the hull, and an ozone standing at the bottom wall opening of the hull and an ozone at the upper end. It has a guide tube that communicates the generator and has an air intake port.The guide tube is arranged in this guide tube so that the lower end opening projects downward from the bottom wall opening of the hull and the upper end opens into the guide tube. The drive shaft (18) is coaxially placed in the outer cylinder (14) with the water inlet at the upper end, and the water and gas between the outer cylinder and the outer cylinder are rotated by rotating the drive shaft at high speed. And a gas-liquid mixing device for jetting into the water through the lower end opening of the outer cylinder.

For steering the hull, it is preferable to dispose ultrasonic sensors for detecting obstacles at the front end and the left and right of the front end of the hull, and to automatically control by the detection signal of the ultrasonic sensor.

Further, it is preferable to tie a bag body at the rear end of the hull for collecting suspended matter such as aquatic plants that have died and floated on the water surface.

[0011]

[Action]

 When the hull is floating on the water, water has invaded the guide cylinder with the bottom wall opening at the bottom opening to a certain level, and the water flow opened at the top of the outer cylinder of the gas-liquid mixing device. The inlet is located slightly below the water level in the guide cylinder. Further, water has penetrated 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 low speed by the propulsion device. When the gas-liquid mixing device is driven, the 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. The water continuously flows between the outer cylinder and the drive shaft through the space between the outer cylinder and the outer cylinder, and the mixed gas of ozone and air generated by the ozone generator is generated from the upper end opening of the outer cylinder and the water inlet. It is continuously sucked between the outer cylinder and the drive shaft.

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

When gas dissolves in water, not only air but also ozone dissolves. Therefore, by the action of this ozone, bacteria and microorganisms are more effectively killed, and contaminants such as ammonia are efficiently decomposed. To achieve water purification.

When an ultrasonic sensor is attached to the hull and the ultrasonic sensor detects an obstacle in the navigation of the hull and automatically controls the steering of the hull, the hull can be operated unmanned. , 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 is allowed to travel at a low speed, there is no hindrance to the hull's navigation with the bag tied.

[Effect of the device]

 Since the present invention has the above-mentioned configuration, it has the following effects. Since the hull is equipped with an ozone generator, a guide tube, and a gas-liquid mixing device, the ozone of the ozone generator is agitated and mixed with water from the guide tube by the gas-liquid mixing device into fine bubbles.

Therefore, purification of water can be achieved powerfully and safely.

Ozone and the agitated mixture of air and water ejected from the gas-liquid mixing device mounted on the hull are ejected downward from the opening portion of the bottom wall of the hull, and therefore reach a deep position in water. Therefore, purification of water can be achieved in a sufficiently deep range.

Since the jetting of the agitated mixture of ozone and air into water is performed while the hull is traveling at a low speed, the jetting point of the agitated mixture is all the places where the hull sailed, and thus the water Purification can be achieved over a wide area of the lake.

When the navigation of the hull is achieved by the automatic steering using the ultrasonic sensor and the computer, the operation of the hull can be achieved unmanned, and thus the purification of water over a wide range over a long time can be achieved. Can be achieved safely and at low cost.
