Abstract

PROBLEM TO BE SOLVED: To largely improve the profitability of a large scale algae plantation for energy utilization thereof by using an unmanned and automated algae- harvesting boat instead of a conventional manual operation or a simply mechanized operation of poor profitability. SOLUTION: This algae-cutting boat comprises a plurality of sensors 16 that are attached to a net for culturing algae whose harvesting operations are previously scheduled, where the boat can be propelled in a plurality of directions, as it follows these sensors 16, a pole 4 for controlling depth that can follow the water depth of the algae-culturing net, an algae cutter 8 set to the depth-controlling pole 4, conveying buckets and an automatic moor 12 for a cut algae-conveying boat.

[Means for Solving the Problems] It is basically unmanned. 2. The main movement is based on a computer, and the correction uses a radio control method. 3. Fine adjustment is performed by various sensors, magnetism, light, high frequency, ultrasonic wave, sound, electric current, etc., and control and control by a transmitter / receiver. 4. The reaping boat has a plurality of propulsion units having forward and backward and sensor following control functions. 5. The reaping unit has a plurality of blades having functions such as rotation, reciprocation, and jet flow, and a conveyor, a jet, and a composite device for transporting the cut algae to the deck of the reaping vessel. 6. The reaping vessel performs forward, backward, and left-right corrections according to the reaping unit's ability while faithfully observing the prescribed position and prescribed trajectory of the algae planting net. The mowing unit has a vertical movement mechanism that corrects the variation in the installation depth of the algae planting net from the water surface and a sensor tracking reception function, and performs mowing while maintaining the distance to the algal planting net accurately.

The operation will be described with reference to FIG. The reaping vessel main body 1 has necessary power sources and controller equipment. The planting net 14 is provided with a positioning sensor 7 in which a cutting position is determined in advance. When approaching the set position from the command boat, the mode is switched to the automatic mode. When the mode is switched to the automatic mode, the depth adjusting column 4 is lowered and the depth adjusting column 4 is lowered.
The receiver 6 mounted on the lower part of the vegetation detects and localizes the sensor 7 of the planting net 14. Further, the left-right control of the mowing vessel is performed by the sensor 16 mounted on the sea surface or the planting net. 17 is sensed and controlled by driving a plurality of sensor-following propellers. When the mowing vessel is ready to move, the cutting blade 8 rotates through the mowing motor 5 and the blade driving chain 10 to cut the algae. The cut algae are loaded on a carrier boat 15 which is moored in advance by a transport bucket conveyor 11 provided with suction by a jet provided at the rear. Reference numeral 9 denotes a motor for driving the conveyor bucket conveyor, 13 denotes an auxiliary conveyance chute, 12 denotes a carrier mooring unit, 2 denotes a forward / reverse propeller, and 3 denotes a sensor follower propeller.
