[0015] A method for using an auxiliary vessel for marine aquaculture comprises the following steps:

[0016] S1. After the second motor in the bracket assembly is controlled by the remote control to run, it drives the first gear to rotate. The first gear can drive the second gear, the first rotating shaft and the second pulley to rotate synchronously. At this time, under the action of the first pulley and the first transmission belt, the rotational force will be transmitted to the second rotating shaft below the first pulley. When the second rotating shaft rotates, it will drive the second bevel gear inside the oar frame to rotate. At this time, the second bevel gear will cooperate with the first bevel gear to drive the third rotating shaft to rotate. When the third rotating shaft rotates, the third pulley at its end cooperates with the second transmission belt to drive the fourth rotating shaft to rotate. When the fourth rotating shaft rotates, the paddle wheel located underwater and installed on the surface of the fourth rotating shaft will generate forward and backward thrust on the hull through rotation, thereby pushing the hull forward;

[0017] S2, control the third motor to drive the worm to rotate, at this time the worm will drive the turbine above the mounting plate to rotate, and when the turbine rotates, it will drive the third gear below to rotate through the connecting shaft at the bottom, because the third gear is meshed with the fixed gear above the oar rack, and the fixed gear and the oar rack are in a rotational connection relationship with the second rotating shaft and the second bevel gear, so when the third gear rotates, it will drive the oar rack and the paddle wheel to turn, thereby changing the direction of travel of the hull. The driving system of the entire paddle mechanism can be powered by two motors, and the overall structure is compact, which can effectively reduce the overall volume of the device, reduce equipment cost and use flexibility;

[0018] S3. When feeding, add the feed required for the corresponding breeding area into the silo. At this time, the feed will not be discharged from the bottom of the feeding channel under the action of the auger blade. When the hull reaches the designated area, the first motor is started during the movement. After the first motor is started, the auger blade will be driven to rotate. Since the inside of the silo is inclined, the feed will slide toward the feeding channel, and then will be transported downward under the action of the auger blade.

[0019] S4. Under the action of the auger blades, the feed that is transported downward will squeeze the plug downward. At this time, a gap will appear between the plug squeezing spring and the telescopic rod after contraction and the concave channel, so that the feed is discharged from the expansion port at the bottom of the feeding channel to complete the feeding operation. When the first motor stops running, the auger blades stop transporting the feed downward. At this time, as the pressure above the plug decreases, the spring will rebound and cooperate with the telescopic rod to make the plug move upward stably, and then cooperate with the concave channel to block the feeding channel, so that the feed stops being discharged.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When in use, the overall structure is simple and reasonable. The three motors can be remotely controlled to complete feeding, traveling and steering. There is no need to manually feed the feed by boat. After driving the hull to the feeding area, the first motor can be kept running to continue feeding. After stopping, the internal structure can immediately stop feeding. The operation is convenient, which greatly reduces the cost of marine aquaculture.

[0022] 2. When in use, the driving system of the entire paddle mechanism is powered by two motors, and the overall structure is compact, which can effectively reduce the overall volume of the device, reduce equipment costs and improve flexibility of use;

[0023] 3. When in use, one side of the oar frame is closed, and the third pulley, the fourth pulley and the second transmission belt are closed by installing a protective cover, which can effectively protect the fourth pulley and the second transmission belt located under the water surface from being corroded by seawater. In addition, the third motor, the worm gear and the turbine are closed by arranging an installation cover above the installation plate, so as to protect the steering transmission structure and prevent the intermittently used third motor and the transmission structure from being contaminated and affecting the steering of the hull. The overall core protection performance is high, ensuring the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

When the hull 1 reaches the designated area, the first motor 210 is started during the movement. After the first motor 210 is started, the auger blade 211 will be driven to rotate. Since the interior of the silo 201 is inclined, the feed will slide toward the discharge channel 202.

When the second rotating shaft 405 rotates, it will drive the second bevel gear 505 inside the oar rack 501 to rotate.

When the third rotating shaft 503 rotates, the third pulley 506 at its end cooperates with the second transmission belt 509 to drive the fourth rotating shaft 507 to rotate. When the fourth rotating shaft 507 rotates, the paddle wheel 511 located underwater and installed on the surface of the fourth rotating shaft 507 will generate forward and backward thrust on the hull 1 through rotation, thereby pushing the hull 1 to move forward. During the process, the third motor 603 is controlled to drive the worm 604 to rotate. At this time, the worm 604 will drive the turbine 605 above the mounting plate 601 to rotate. When the turbine 605 rotates, it will drive the third gear 607 below to rotate through the connecting shaft 606 at the bottom. Since the third gear 607 is meshed with the fixed gear 502 above the oar rack 501, and the fixed gear 502 and the oar rack 501 are in a rotational connection relationship with the second rotating shaft 405 and the second bevel gear 505, when the third gear 607 rotates, it will drive the oar rack 501 and the paddle wheel 511 to turn, thereby changing the direction of travel of the hull 1. The driving system of the entire paddle mechanism can be powered by two motors, and the overall structure is compact, which can effectively reduce the overall volume of the device.While reducing the equipment cost, it improves the flexibility of use. In addition, one side of the oar rack 501 is closed, and the third pulley 506, the fourth pulley 508 and the second transmission belt 509 are closed by installing a protective cover 510, which can effectively protect the fourth pulley 508 and the second transmission belt 509 located under the water surface from being corroded by seawater. The third motor 603, the worm 604 and the turbine 605 are closed by arranging an installation cover 602 above the installation plate 601, which plays an effect of protecting the steering transmission structure, preventing the third motor 603 and the transmission structure from being polluted and affecting the steering of the hull 1.

A mounting cover (602) is fixedly connected to the top of the mounting plate (601), and the mounting cover (602) is arranged outside the third motor (603), the worm (604) and the turbine (605).

5. A method for using an auxiliary vessel for marine aquaculture, characterized in that: The use of the marine aquaculture auxiliary vessel as claimed in claim 4 comprises the following steps: S1. The second motor (401) in the support assembly (3) is controlled by a remote controller to run and drive the first gear (402) to rotate. The first gear (402) can drive the second gear (404), the first rotating shaft (403) and the second pulley (407) to rotate synchronously. At this time, under the action of the first pulley (406) and the first transmission belt (408), the rotational force is transmitted to the second rotating shaft (405) below the first pulley (406). When the second rotating shaft (405) rotates, it drives the second cone inside the oar frame (501) to rotate. The gear (505) rotates, and the second bevel gear (505) cooperates with the first bevel gear (504) to drive the third rotating shaft (503) to rotate. When the third rotating shaft (503) rotates, the third pulley (506) at the end thereof cooperates with the second transmission belt (509) to drive the fourth rotating shaft (507) to rotate. When the fourth rotating shaft (507) rotates, the paddle wheel (511) located underwater and mounted on the surface of the fourth rotating shaft (507) generates forward and backward thrust on the hull (1) through rotation, thereby pushing the hull (1) forward. S2, controlling the third motor (603) to drive the worm (604) to rotate, and the worm (604) will drive the turbine (605) above the mounting plate (601) to rotate, and when the turbine (605) rotates, it will drive the third gear (607) below to rotate through the connecting shaft (606) at the bottom. Since the third gear (607) is meshed with the fixed gear (502) above the oar rack (501), and the fixed gear (502) and the oar rack (501) are in a rotational connection relationship with the second rotating shaft (405) and the second bevel gear (505), when the third gear (607) rotates, it will drive the oar rack (501) and the paddle wheel (511) to turn, thereby changing the direction of travel of the hull (1). The driving system of the entire oar mechanism can be powered by two motors; S3. When feeding, the feed required for the corresponding breeding area is added to the silo (201). At this time, the feed will not be discharged from the bottom of the feeding channel (202) under the action of the auger blade (211). When the hull (1) reaches the designated area, the first motor (210) is started during the movement. After the first motor (210) is started, the auger blade (211) is driven to rotate. Since the inside of the silo (201) is inclined, the feed will slide in the direction of the feeding channel (202) and then be transported downward under the action of the auger blade (211); S4. Under the action of the auger blade (211), the feed that is transported downward will press the plug (208) downward. At this time, the plug (208) squeezes the spring (207) and the telescopic rod (206) to contract, and a gap appears between the plug and the concave channel (209), thereby allowing the feed to be discharged from the bottom expansion opening (204) of the feeding channel (202) to complete the feeding operation. When the first motor (210) stops running, the auger blade (211) stops transporting the feed downward. At this time, as the pressure above the plug (208) decreases, the spring (207) will rebound and cooperate with the telescopic rod (206) to cause the plug (208) to move upward stably, and then cooperate with the concave channel (209) to block the feeding channel (202), thereby stopping the discharge of the feed.
