Description

Technical Field

[0001] The present invention relates to the field of aquaculture, and in particular to an in-situ cleaning ship for aquaculture cages. Background Art

[0002] China is a major country in seafood farming and consumption, with both the farming and consumption volumes ranking first in the world. When conducting artificial farming of seafood, cage farming is one of the most common farming methods, which is suitable for the farming of many precious seafood such as sea cucumbers, oysters, and scallops.

[0003] During the cage farming process, the netting of the cages is often attached by various aquatic organisms. These aquatic organisms will hinder the water exchange between the cages and the outside world, seriously affecting the farming output and cycle, and even causing a large number of deaths of seafood in severe cases. Therefore, it is necessary to regularly clean the cages during the farming process.

[0004] The traditional cleaning of offshore aquaculture cages is mostly carried out manually. That is, the main cable and the cage are lifted from the sea water by the lifting device on the ship, and the worker holds a water spray pipe to wash the cage comprehensively. After the washing is completed, the main cable is lowered. After the ship moves forward a certain distance (generally 3 - 5 meters), the above operation is repeated.

[0005] This operation method has low work efficiency and requires a large amount of manual labor. Its time cost and labor cost are relatively high, seriously restricting the large-scale development of cage farming. Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention

[0006] The present invention is to solve the above-mentioned deficiencies of the prior art, and proposes an in-situ cleaning ship for aquaculture cages with a simple structure, ingenious design, reasonable layout, which can greatly save manual labor and improve the cleaning efficiency.

[0007] The technical solution of the present invention is: an in-situ cleaning ship for aquaculture cages, including a hull 1, characterized in that: a cable guiding mechanism 2 is arranged at the bow of the hull 1, a cleaning mechanism 3 is arranged on the side of the hull 1 behind the cable guiding mechanism 2, a counterweight 4 symmetrically distributed with the cleaning mechanism 3 is also arranged on the other side of the hull 1, and a seawater pump 5 is arranged inside the hull 1.

[0008] The cable guiding mechanism 2 includes a support plate 6 fixed on the hull 1. One end of the support plate 6 is provided with a pair of arc-shaped plates 7. The arc surfaces of the arc-shaped plates 7 face the bow direction. The pair of arc-shaped plates 7 together form a trumpet-shaped opening with an arc-shaped edge.

[0009] The cleaning mechanism 3 includes a support frame 8 fixedly connected to the hull 1. A front guiding groove 9 is provided at the front end of the support frame 8. The front guiding groove 9 includes a semi-cylindrical inclined guiding portion 10. The front end of the inclined guiding portion 10 is an arc surface portion 11. The shape of the arc surface portion 11 matches the outer contour of the hanging cage. The rear end of the inclined guiding portion 10 is connected to the front entrance of a limiting guiding cage 13 which is horizontally distributed on the support frame 8 through a smooth front transition portion 12. A smooth rear guiding groove 14 is provided at the rear exit of the limiting guiding cage 13.

[0010] A main pipeline 15 is provided at the bottom of the support frame 8. The middle of the main pipeline 15 is connected to the outlet end of a water inlet pipeline 16. The inlet end of the water inlet pipeline 16 is connected to the outlet end of a seawater pump 5. At least two annular flushing pipes 17 are equally spaced on the main pipeline 15. The bottom of the annular flushing pipe 17 is interconnected with the main pipeline 15. The top of the annular flushing pipe 17 has a notch 18. A plurality of nozzles 19 are also provided on the inner wall of the annular flushing pipe 17. The nozzles 19 are evenly distributed in the circumferential direction.

[0011] The nozzles 19 are inclined with respect to the axis of the limiting guiding cage 13, and the water spraying openings of the nozzles 19 face the bow direction.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The in-situ cleaning ship for the aquaculture hanging cage with this structural form has a simple structure, ingenious design and reasonable layout. Aiming at the various deficiencies existing in the traditional cleaning method of the aquaculture hanging cage, a special structure is designed. It can automatically complete the cleaning operations of a plurality of hanging cages suspended on the main cable in sequence during the traveling process without manual intervention and operation. For each main cable, the operator only needs to operate once (placing the main cable in the cable guiding mechanism and the annular flushing pipe), which greatly reduces the manual labor intensity and can effectively improve the work efficiency. At the same time, it has no complex power mechanical structure and is very suitable for being refitted on the existing small fishing boats, which also saves a large amount of costs and is more conducive to its popularization and application in this field.

Detailed implementation manner

[0019] The following will describe the detailed implementation manner of the present invention with reference to the drawings as follows: As Figure 1 、 Figure 2 shown, a cleaning ship for in-situ cleaning of a culture cage includes a hull 1. A mooring line guiding mechanism 2 is provided at the bow of the hull 1. A cleaning mechanism 3 is provided on the side of the hull 1 behind the mooring line guiding mechanism 2. A counterweight 4 symmetrically distributed with the cleaning mechanism 3 is further provided on the other side of the hull 1. A seawater pump 5 is also provided inside the hull 1.

[0020] The mooring line guiding mechanism 2 includes a support plate 6 fixed on the hull 1. One end of the support plate 6 is provided with a pair of arc plates 7. The arc surfaces of the arc plates 7 face the bow direction. This pair of arc plates 7 together form a trumpet-shaped opening with an arc-shaped edge.

[0021] The cleaning mechanism 3 includes a support frame 8 fixedly connected to the hull 1. A front guiding groove 9 is provided at the front end of the support frame 8. The front guiding groove 9 includes a semi-cylindrical inclined guiding part 10. The front end of the inclined guiding part 10 is an arc surface part 11. The shape of the arc surface part 11 matches the outer contour of the cage. The rear end of the inclined guiding part 10 is connected to the front end inlet of a limit guiding cage 13 horizontally arranged on the support frame 8 through a smooth front transition part 12. A smooth rear guiding groove 14 is provided at the rear end outlet of the limit guiding cage 13.

[0022] A main pipeline 15 is provided at the bottom of the support frame 8. The middle of the main pipeline 15 is communicated with the outlet end of a water inlet pipeline 16. The inlet end of the water inlet pipeline 16 is connected to the outlet end of the seawater pump 5. At least two annular flushing pipes 17 are equally spaced on the main pipeline 15. The bottom of the annular flushing pipe 17 is communicated with the main pipeline 15. The top of the annular flushing pipe 17 has a notch 18. A plurality of nozzles 19 are also provided on the inner wall of the annular flushing pipe 17. The nozzles 19 are evenly distributed in the circumferential direction.

[0023] The nozzles 19 are inclinedly distributed with respect to the axis of the limit guiding cage 13, and the water spraying ports of the nozzles 19 face the bow direction.

[0024] The working process of the in-situ cleaning ship for aquaculture hanging cages according to the embodiments of the present invention is as follows: First, drive the hull 1 to navigate to the sea area where the aquaculture hanging cages are located, move the hull 1 to one end of a main cable, with the bow facing the direction of the other end of the main cable. The staff on the hull 1 lift the main cable and place it into the annular flushing pipe 17 through the notch 18 at the top of the annular flushing pipe 17. At this time, the main cable is located inside the limit guiding cage 13 and the annular flushing pipe 17, and at the same time, the main cable is placed in the opening gap between the two arc-shaped plates 7. Then, place the pipeline connected to the water inlet of the seawater pump 5 below the sea level, and the preparatory work is completed;

[0025] Drive the hull 1 to move forward uniformly along the direction of the main cable, and turn on the seawater pump 5. During the process of the hull 1 moving along the main cable, the cable guiding mechanism 2 can ensure that the main cable will not break away from the cleaning mechanism 3 at the rear. When the arc surface part 11 in the cleaning mechanism 3 contacts the side wall of the hanging cage, the arc surface part 11 can closely adhere to the outside of the hanging cage. As the hull 1 moves forward, the front guiding groove 9 moves towards the hanging cage, lifting the hanging cage. After the hanging cage passes through the inclined guiding part 10, its posture changes from the vertical state to the horizontal state. The hanging cage in the horizontal state will enter the limit guiding cage 13 and move backward (towards the stern direction) along the axial direction of the limit guiding cage 13;

[0026] During the movement of the hanging cage, the seawater pumped from the sea by the seawater pump 5 will enter the main pipeline 15 through the water inlet pipeline 16, and then enter each annular flushing pipe 17 through the main pipeline 15, and finally be sprayed on the surface of the hanging cage through multiple nozzles 19 on the inner wall of the annular flushing pipe 17, so as to wash down the aquatic organisms attached to its surface. The washed impurities and the water body will return to the ocean together; After the hull 1 travels a certain distance, the tail end of the hanging cage after being washed detaches from the rear guiding groove 14 and naturally hangs down to the vertical state again;

[0027] During the process of the hull 1 sailing from one end to the other end of the main cable, the cleaning mechanism 3 will automatically wash all the hanging cages on this main cable once, and then take out the main cable from the cable guiding mechanism 2 and the annular flushing pipe 17. Drive the hull 1 to sail to one end of another main cable and repeat the above operations to realize the automatic cleaning operation of all the hanging cages on the second main cable.
