Description

Technical Field

[0001] The present invention relates to a marine in-situ cage cleaning machine, belonging to the technical field of aquaculture. Background Art

[0002] Scallops have a wide breeding area in the eastern coastal areas of China. When breeding scallops, scallop cages are mainly used for scallop placement. During the breeding process, parasitic and competing organisms such as shellfish and algae, as well as sand blocks, will adhere to the scallop cages and block the mesh holes on the scallop cages. When in use, it is necessary to remove the sand blocks and other substances adhering to the cages. If not treated, it will reduce the dissolved oxygen in the scallop cages, and then prevent plankton from entering the cages, resulting in scallops not being able to catch enough plankton for feeding, which is not conducive to the growth of scallops. Therefore, it is necessary to regularly clean the surface of the cages to ensure their use effect. Most of the existing cleaning methods for cages are manual, but this cleaning method requires a large amount of manpower and material resources, consumes a lot of time and energy, and has a poor cleaning effect. In the prior art, the Chinese patent application number 201911022223.7 discloses a multi-functional and efficient cage cleaning machine, including a machine shell, a controller, a left feeding roller, a right feeding roller, two groups of right positioning plates, a feeding belt, an upper elastic rolling roller, a lower elastic rolling roller, two groups of limiting springs, two groups of fixed seats, two groups of left positioning plates, a left discharging roller, a right discharging roller, and a discharging belt. A first transmission gear is arranged on the left feeding roller, and both groups of left positioning plates are installed in the left half area of the bottom of the machine shell. A grid is arranged in the right half area of the bottom of the machine shell. The left discharging roller and the right discharging roller are connected by a discharging belt. A second transmission gear is arranged on the right discharging roller. It also includes a first high-pressure water supply pipe, a second high-pressure water supply pipe, and a low-pressure water supply pipe. A plurality of high-pressure fan-shaped nozzles are respectively communicated and arranged on the first high-pressure water supply pipe and the second high-pressure water supply pipe, and a plurality of low-pressure nozzles are communicated and arranged on the low-pressure water supply pipe. It can improve the cleaning effect on the surface of the cage. However, this cleaning machine cannot be applied to marine use and can only transport the cage to land for cleaning, which is time-consuming and laborious. Summary of the Invention

[0003] To solve the problems existing in the prior art, the present invention proposes a marine in-situ cage cleaning machine, aiming to provide a marine cage cleaning machine that can perform cleaning work at sea, so as to remove the attached substances on the cage, significantly improve the cleaning efficiency of the scallop breeding cage, reduce the trouble of sea-land transportation, reduce the manual labor intensity, ensure the effective use of the scallop cage, and further promote the growth of scallops and improve the breeding efficiency.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] To further understand the content of the present invention, the following further elaborates on this technical solution in combination with specific implementation manners.

[0029] Embodiment 1: This embodiment provides a marine in-situ cage cleaning machine. The term "in-situ" means that the cage does not need to be detached from the buoyancy rope during cleaning and only needs to be lifted or lowered. The cage cleaning machine in this embodiment is as shown in Figures 1 to 11 and includes a lifting mechanism, a telescopic mechanism, and a decontamination mechanism. The lifting mechanism is used to drive the cage 26 to move within the decontamination mechanism. As a specific implementation manner of this embodiment, the lifting mechanism includes a hydraulic winch 20, a frame 21, a hook 22, and a hydraulic station 23. The hydraulic winch 20 is installed on the frame 21, the frame 21 is erected on the hull 27, the hook 22 is arranged below the hydraulic winch 20, and the hydraulic station 23 provides a power source for the hydraulic winch 20. The hydraulic station 23 is installed on the telescopic mechanism. The hydraulic winch 20 is used to drive the cage 26 to move up and down within the decontamination mechanism. Specifically, a lifting rope 24 is hung at the top of the cage 26, and the lifting rope 24 is connected to the buoyancy rope 25. The rope of the hydraulic winch 20 is lowered into the sea so that the hook 22 hooks the buoyancy rope 25, thereby lifting or lowering the cage 26.

[0030] A telescopic mechanism for driving a decontamination mechanism to move to a designated position. As a specific implementation manner of this embodiment, the telescopic mechanism includes an upper bracket 11, a lower bracket 12, a moving guide rail 13, a connecting frame 14, and a hydraulic cylinder 15. Both the upper bracket 11 and the lower bracket 12 are provided with four wheel bases 17, and each wheel base 17 is installed with a roller 16. The upper bracket 11 and the lower bracket 12 are arranged oppositely so that the two rollers 16 correspond to each other one by one. The moving guide rail 13 is located between the rollers 16 of the upper bracket 11 and the lower bracket 12. The connecting frame 14 is installed between the parallel moving guide rails 13. A fixed block 18 is provided at the bottom of the A end of the connecting frame 14, and the B end of the connecting frame 14 is used to connect the decontamination mechanism. Through the design of the rollers 16 and the moving guide rail 13, the stability of the connecting frame 14 during movement is ensured. The hydraulic cylinder 15 is installed on the lower bracket 12, and the piston rod 19 of the hydraulic cylinder 15 is softly connected to the fixed block 18 through a floating joint to avoid unsmooth movement during hard connection. When the piston rod 19 extends, the fixed block 18 moves horizontally, thereby driving the B end of the connecting frame 14 to move between the upper bracket 11 and the lower bracket 12. When the piston rod 19 retracts, it drives the B end of the connecting frame 14 to move away from the upper bracket 11. When the moving guide rail 13 moves, it drives the rollers 16 to rotate on the moving guide rail 13. One side of the upper bracket 11 and the lower bracket 12 is installed on the cabin, and the other side is installed on the ship's side. In this way, when the piston rod 19 retracts, it drives the B end of the connecting frame 14 to move away from the upper bracket 11, and then the decontamination mechanism connected to the B end of the connecting frame 14 extends out of the hull 27.

[0031] A decontamination mechanism for cleaning the attachments on the cage 26. As a specific implementation manner of this embodiment, the decontamination mechanism includes a mounting bracket 1, a ring body 2, and a brush 3. The ring body 2 has a first notch 4, and the brush 3 is sleeved on the outer periphery of the ring body 2. Both ends of the mounting bracket 1 are respectively connected to the first ring body 2 and the telescopic mechanism. The mounting bracket 1 is specifically installed at the B end of the connecting frame 14 of the telescopic mechanism. In this embodiment, the decontamination mechanisms are arranged at intervals on the connecting frame 14, and the installation positions of the decontamination mechanisms are opposite to the extending direction of the piston rod 19. There are a total of 5 decontamination mechanisms, which can be specifically set according to the size of the hull 27. By simultaneously cleaning the cage 26 with multiple decontamination mechanisms, the cleaning efficiency of the cage 26 is improved.

[0032] Embodiment 2: As Figures 1 to 11As shown, on the basis of Example 1, the decontamination mechanism in this embodiment further includes a water pipe 5, a connector 6 and two transition plates 7. The water pipe 5 is connected and fixed to the ring body 2 through the connector 6. The water pipe 5 is provided with a water inlet 8 and a water outlet 9. The water inlet 8 is connected to a water pump, and the water outlet 9 is used to flush the net cage 26. The water pipe 5 has a second notch 10 at both ends, and two transition plates 7 are installed at the second notch 10. The transition plate 7, the first notch 4 and the second notch 10 together constitute a clearance opening for the suspension rope 24 to pass through. The opening of the transition plate 7 away from the end where the water pipe 5 is located is larger than the opening close to the end where the water pipe 5 is located, that is, the two transition plates 7 are installed to form a V-shaped opening to guide the suspension rope 24 to pass through, so that the net cage 26 can smoothly enter the inner side of the decontamination mechanism.

[0033] In the actual application process of the present invention, taking Example 2 as an example, Figures 1 to 11 As shown, first, the ship is driven to the designated position, the hydraulic cylinder 15 drives the connecting frame 14 and the decontamination mechanism to move to the outside of the hull 27, and the two hydraulic winches 20 are lowered into the sea, so that the hook 22 below hooks the buoyancy rope 25. At this time, the hydraulic winch 20 is operated to raise the buoyancy rope 25 and the net cage 26 connected thereto, and the lifting rope 24 above the net cage 26 is aligned with the clearance opening, so that the lifting rope 24 enters the inside of the water pipe 5, thereby completing the entry of the net cage 26 into the inside of the water pipe 5; the hydraulic winch 20 is operated to repeatedly raise and lower the net cage 26, and the net cage 26 In the process of moving up and down, it is constantly in contact with the brush 3, and the brush 3 brushes the surface of the net cage 26. At the same time, the water outlet 9 sprays a large amount of liquid to wash the surface of the net cage 26, so that the attachments such as waterweed adsorbed on the surface of the net cage 26 are washed away, and the purpose of removing the attachments on the surface of the net cage 26 is achieved, so that the plankton enters the net cage 26, promotes the growth of scallops, and provides a double cleaning method to make the net cage 26 cleaner; in addition, the present invention directly cleans at sea, and after cleaning, the net cage 26 is put back into the sea to avoid sea and land transportation, which is time-consuming and labor-intensive. According to the needs, the decontamination mechanism is driven by the hydraulic cylinder 15 to move into or out of the ship to realize the position switching of the decontamination mechanism, that is, when the net cage 26 needs to be cleaned, the decontamination mechanism is extended out of the ship under the action of the hydraulic cylinder 15, and when the net cage 26 is cleaned, the decontamination mechanism is retracted into the ship under the action of the hydraulic cylinder 15, so that there is no obstruction when the ship is driving normally and docking. The hydraulic station 23 provides a power source for the hydraulic cylinder 15 and the hydraulic winch 20.
