[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] See also Figure 1-3 A multifunctional floating raft maintenance and fish gathering device includes a frame-type floating raft 1, a culture cage 14, and a cage column 13. A ballast tank 15 is provided inside the frame-type floating raft 1, and a propeller 2 is provided at the circular through hole in the middle of the ballast tank 15. A deployable fishing net 3 is installed in the area outside the ballast tank 15 and the propeller 2. Rotatable net washing nozzles 4 are installed around and on the bottom of the frame-type floating raft 1. A control station 6 is fixedly installed on the culture cage 14. A vertical fish-driving board 12 is installed on the outside of the opposite side of the frame-type floating raft 1.

[0029] The control station 6 is equipped with an umbilical cord 5, the end of which, away from the control station 6, is connected to the frame-type floating raft 1. A high-pressure pump station is installed on the aquaculture cage 14, with a connecting water pipe installed between the rotatable net-washing nozzle 4 and the high-pressure pump station. There are four cage columns 13. A ballast water line is installed inside the frame-type floating raft 1, and this line is connected to the ballast pump on the aquaculture cage 14 via the umbilical cord 5 to inject and discharge ballast water.

[0030] In addition, a raft depth detector 7 is provided on the frame-type raft 1 , a ballast liquid level monitor 8 is installed in the ballast tank 15 , and a deployable fishing net monitor 9 is provided on the deployable fishing net 3 .

[0031] It should be noted that the deployable fishing net 3 is a clamshell or swing-open type, and the propeller 2 is a shaftless, propellerless propeller, which is fish-safe, low-vibration, and low-noise, minimizing impact on fish during operation. The raft is equipped with a net-washing nozzle, a deployable fishing net, and a vertical fish-repelling board. The frame-type raft 1 is raised and lowered to perform net-washing and fish-collecting operations efficiently and effectively, significantly reducing operating costs. The frame-type raft 1 is constructed of steel or other reliable materials and can be square, round, diamond, or X-shaped.

[0032] In this embodiment, a frame-type floating raft 1 is provided with two symmetrically arranged net cages. Guide rails 11 are mounted at the four corners of the two net cages on opposite sides. Clamping devices are mounted on the guide rails 11. The four guide rails 11 are respectively connected to the four net cage columns 13. The frame-type floating raft 1 is controlled via an umbilical cord 5.

[0033] When this embodiment is in use, the propeller 2 drives the frame-type floating raft 1 to rise and fall through the balance between its own buoyancy and gravity, and the clamping device on the net cage sliding guide 11 makes the frame-type floating raft 1 float at a fixed depth, and the net washing nozzles 4 arranged around the frame-type floating raft and the expandable fishing net 3 arranged inside the frame-type floating raft are used to clean the net and gather fish.

[0034] Furthermore, the frame-type raft 1 is equipped with a ballast tank 15, a propeller 2, an expandable fishing net 3, a net-washing nozzle 4, a vertical fish-repelling plate 12, and a guide rail 11. By adjusting the water volume in the ballast tank 15, adjusting the thrust of the propeller 2, and controlling the clamping device according to operational needs, net washing or fish gathering operations can be conveniently performed, reducing labor costs and improving work efficiency and comprehensiveness, making it suitable for large-scale, mechanized, modern, and intelligent aquaculture. Example

[0035] See also Figure 4-6 In this embodiment, an adjustment structure 16 is provided on the vertical fish-driving plate 12, and the adjustment structure 16 includes an adjustment plate 1601, a motor 1602, a bidirectional screw 1603, a moving block 1604 and a support rod 1605. The moving block 1604 is threadedly connected to the outside of the bidirectional screw 1603, and both ends of the support rod 1605 are hinged with a hinge seat 1606, and the two hinge seats 1606 are fixed to the moving block 1604 and the opposite side of the adjustment plate 1601 on the separated side.

[0036] Among them, the number of bidirectional screws 1603, moving blocks 1604 and support rods 1605 are two each. The two bidirectional screws 1603 are installed with couplings 1607. The left end of the left bidirectional screw 1603 is fixed to the output shaft of the motor 1602, and the end of the right bidirectional screw 1603 away from the coupling 1607 is connected to the internal rotation of the vertical fish-driving plate 12.

[0037] The vertical fish chasing plate 12 has a receiving slot 1202 formed inside, and a groove 1203 formed inside the receiving slot 1202. Sliders 1608 are fixedly mounted on the outer wall of the opposite side of the adjustment plate 1601. The two slides 1608 are slidably connected to the two grooves 1203. The cooperation between the slides 1608 and the grooves 1203 allows the adjustment plate 1601 to be stably raised and lowered.

[0038] It should be noted that the threads of the two bidirectional screws 1603 are opposite, allowing the two moving blocks 1604 to move relative to or away from each other. The two top hinged seats 1606 are located in the middle of the lower surface of the adjustment plate 1601. The end of the right bidirectional screw 1603 away from the coupling 1607 is connected to the internal bearing of the vertical fish-repelling plate 12.

[0039] Among them, the exterior of the vertical fish-repelling plate 12 is detachably mounted with an inspection cover 1201, which facilitates the inspection of the internal components of the vertical fish-repelling plate 12. The inspection cover 1201 is provided with sealing gaskets at the edges thereof. The motor 1602 is fixedly mounted on the exterior of the vertical fish-repelling plate 12 and is a waterproof motor.

[0040] When this embodiment is in use, the motor 1602 is started, and then the output shaft thereof drives the two bidirectional screws 1603 to rotate through the coupling 1607. Since the threads of the two bidirectional screws 1603 are opposite, the two moving blocks 1604 can be displaced relative to or apart from each other, thereby adjusting the height of the adjustment plate 1601, extending the height of the vertical fish-driving plate 12, and preventing the fish from jumping out of the frame-type floating raft 1 when gathering fish. Example

[0041] See also Figure 7 In this embodiment, a shielding structure 17 is provided on the outside of the ballast tank 15. The shielding structure 17 consists of a frame 1701, a filter screen 1702 and a mounting plate 1704. The top of the frame 1701 is fixedly connected to the connecting end 1703, and the lower surface of the mounting plate 1704 is fixedly installed with a mounting end 1705 threadedly connected to the connecting end 1703.

[0042] Frame 1701 is hollowed out, and there are five filters 1702, mounted around and on the bottom of frame 1701. Mounting holes are provided within mounting plate 1704. The number of shielding structures 17 is the same as the number of propellers 2. Frame 1701 and filters 1702 are both made of stainless steel.

[0043] When this embodiment is in use, the mounting plate 1704 is installed on the outside of the ballast tank 15, and then the frame 1701 is installed through the cooperation of the connecting end 1703 and the mounting end 1705. When in use, the filter net 1702 can filter impurities to prevent impurities or weeds from entering the cabin and causing damage to the propeller 2.

[0044] The working principle of the above embodiment is:

[0045] When cleaning the net, maintenance is performed. The deployable fishing net 3 on the frame raft 1 is in the recovery state. Water is injected into the ballast tank of the floating raft in a floating state. The injection speed is controlled, and the raft slowly sinks. The high-pressure pump station on the aquaculture facility is turned on, and the net washing nozzles 4 around the raft begin to work. When the buoyancy and gravity of the frame raft underwater are close, the water injection valve is closed, the propeller is started, and the raft is raised and lowered by the propeller 2. When it approaches the bottom net, an alarm signal is received from the raft depth monitoring 7. The raft is now fixed by the clamping device 11 on the guide rail, and the bottom net washing nozzle 4 is turned on. When cleaning is completed, the high-pressure pump station and the nozzle manifold valve are closed, the clamping device 11 is released, and the ballast tank is slowly drained. When the frame raft begins to float along the guide rail 11, the propeller 2 is turned on to control the floating speed of the frame raft 11. When the frame raft floats to a completely floating state, the clamping device on the guide rail 11 is used to lock the frame raft, and the cleaning of the deployable fishing net 3 is completed.

[0046] During adult fish harvesting, the fish gathering function is performed. The deployable fishing net 3 on the raft is in the retrieving state. Water is then injected into the ballast tank 15 of the floating frame raft 1 at a controlled rate, causing the frame raft to slowly sink. When the buoyancy and gravity of the frame raft underwater are close, the water injection valve is closed and the propeller 2 is activated. The raft is raised and lowered by the propeller 2, with the guide rail 11 maintaining its direction. Depending on the depth and density of the fish, fish can be gathered in batches or all at once for adult fish harvesting. When the propeller descends to the desired depth, the deployable fishing net 3 is remotely deployed from the control station 6. Once the deployable fishing net 3 is fully deployed, the propeller 2 is controlled to slowly advance upward while the ballast tank 15 is simultaneously drained. When it rises to the vicinity of the live fish delivery port, the raft is fixed by the holding device on the guide rail 11. At this time, the adult fish fishing work can be carried out. The operation can be repeated until the adult fish fishing work is completed. Then the deployable fishing net 3 is remotely controlled to be retracted. When the frame-type raft floats to the water surface and is in a floating state, the holding device on the guide rail 11 is used to lock the frame-type raft, and the fish gathering function is completed.
