The inlet part 110 is a part that introduces green algae into the ship, and may be located at the head and inclined upward.

In addition, the tip may be located at a depth of 5 to 30 cm so that algae can be drawn into the algae control line.

In this case, as the submerged depth of the green algae control vessel is controlled through the control unit, the position of the inlet portion in the water may be adjusted.

That is, the inlet 110 is located at a shallow water depth when the degree of formation of algae is small, and is located at a deep place when the degree of formation of algae is high, so that the algae can be drawn into the algae control line.

In this way, the inlet part is inclined and the position is adjusted according to the state of the green algae, so that the green algae can be easily collected, and the water can be more effectively purified by reducing the amount of water drawn in together with the green algae.

Separation part 120 is a part from which green algae introduced together with green algae are separated from inlet part 110, and is formed by being connected to inlet part 110, and may include a filter capable of separating green algae and water. .

At this time, one or more filters may be formed, and several filters may be overlapped.

The crushing unit 130 crushes the green algae included in the water moved through the separation unit 120, and may include one or more mixer blades and a mixer motor that drives the mixer blades.

The ultrasonic unit 140 generates ultrasonic waves in the water moved by the crushing unit 130 to destroy remaining cells of the green algae remaining in the water, thereby obtaining an effect of removing the algae. At this time, when the green algae density is high, the effect of removing the algae can be improved by increasing the ultrasonic emission time.

The electrolysis unit 150 supplies current to the water moved from the ultrasonic unit 140 to remove and sterilize algae through the movement of electrons.

More specifically, when electrolysis occurs in water, metal cations and hydroxide ions react to form sediment, and the sediment aggregates green algae and sinks to the bottom, thereby removing algae.

At this time, the electrode for generating metal cations is most preferably aluminum, but is not limited thereto.

In addition, when electrolysis occurs, a sterilization effect can be enjoyed through oxygen and hydrogen generated.

Accordingly, it is possible to remove green algae through the electrolysis unit 150 and improve water quality through a water quality sterilization effect.

In addition, one or more loess propellers 162 may be installed at the top of the loess part 160 so that the sprayed loess can be well dispersed in the green algae.

Accordingly, as the ocher is well dispersed in the water, the green algae are aggregated with the ocher and sink to the bottom, and nitrogen or phosphorus contained in the water can be removed.

The discharge unit 170 is connected to the ocher unit 160 and discharges water moved from the ocher unit 160 to the outside of the green algae control vessel, and may be formed at the lower end of the stern.

Accordingly, the water is purified through the inlet 110, the crushing unit 130, the ultrasonic unit 140, the electrolysis unit 150, the ocher unit 160, and the discharge unit 170, and is discharged to the outside again. By repeating the process, it is possible to improve water pollution by removing residual algae and purifying water.

The body 10 of the unmanned operation algae control vessel according to an embodiment of the present invention may further include an algae moving unit 180 and an algae storage unit 190.

The green algae moving part 180 is a place where green algae introduced from the inlet part 110 moves, and may be connected to the inlet part 110 and formed at the upper end of the main body 10 .

In addition, since the green algae moving unit 180 includes a container belt, the green algae can move from the top of the head to the top of the stern through the green algae moving unit 180.

In addition, the green algae moving unit 180 may include a drying unit 181 on the upper or lower side.

The drying unit 181 has a plurality of holes through which warm air is blown, so that when the green algae move through the moving unit 180, moisture contained in the green algae can be dried.

Accordingly, when storing green algae, it is possible to remove a larger amount of green algae by reducing the weight and volume of the green algae, and also have an effect of reducing fuel consumption due to weight reduction.

In addition, the dried green algae may be moved to the green algae storage unit 190 and stored.

The green algae storage unit 190 is formed in the shape of a groove at the stern end of the green algae moving unit 180, and dried green algae moved through the green algae moving unit 180 can be stored.

In addition, the green algae storage unit 190 may include a container or bag for collecting green algae having a handle therein in order to more conveniently collect the green algae.

Accordingly, when taking out and treating the algae in the algae storage unit 190, only the container or bag containing the algae can be taken out and treated, so that the algae can be treated more easily and the algae storage unit 190 can be used cleanly. .

Referring to FIG. 7 , an unmanned algae control vessel and its system according to the present invention may include an algae control vessel 1, a GPS satellite 2, a sensor unit 3, a terminal 4, and a server 5. .

First, the GPS satellite 2 can determine the real-time location of the green algae control ship 1 and transmit a location signal to the server 5.

The sensor unit 3 may detect a water quality condition around the green algae control line and transmit water quality information to the server 5 . In addition, one or more of a flow measurement sensor, a turbidity sensor, a temperature sensor, an oxygen measurement sensor, and the like are included, but are not limited thereto.

The flow measurement sensor is a sensor that measures the flow rate inflow into the water. In order to secure the amount of dissolved oxygen required according to the degree of contamination in the water, the flow rate inflow into the water is grasped. The rotational speed of the flow generating device 20 can be controlled.

The turbidity sensor is a sensor for measuring the cloudiness of water, and it can be determined that the water pollution is severe as the turbidity is cloudy.

The sources of turbidity are divided into organic and inorganic factors due to natural and artificial causes. Examples of natural factors include floods, microorganisms grown in water, and erosion of rocks, and artificial factors include domestic sewage, industrial wastewater, landfill leachate, etc. there is

The temperature sensor is a sensor that measures the temperature of the water, and since the amount of dissolved oxygen decreases as the temperature of the water increases, the degree of contamination in the water can be determined.

The oxygen measuring sensor is a sensor for measuring the amount of dissolved oxygen, and it may be determined that the water contamination is severe as the amount of dissolved oxygen is lower. Since fish and shellfish or aerobic microorganisms breathe through oxygen dissolved in water, when the amount of dissolved oxygen decreases, fish and shellfish die, and aerobic microorganisms stop proliferating or growing.

In addition, plants also mainly use dissolved oxygen when root respiration, and when dissolved oxygen is low, growth slows down or stops. Accordingly, as the amount of organic matter in water increases, the amount of dissolved oxygen decreases, so dissolved oxygen can measure the degree of contamination in water.

The terminal 4 receives control information from the server 5, grasps the water quality condition, and can monitor and control the algae control ship 1, and remotely operates the algae control ship 1 through the server 5. can do.
