Description

Technical Field

[0001] The invention relates to the technical field of fish catch transfer, and in particular to a flexible marine fish catch transfer system and a fish catch transfer method. Background Art

[0002] Offshore fishing is an important part of the marine economy. Trawling is the main fishing method at sea. The fishing net is dragged on the fishing boat and the fish is stored on the fishing boat. After the fishing boat is fishing at sea, if the catch tank is full or the caught fish needs to be transported back to the port as soon as possible for preservation, if the fishing boat goes back and forth to the port to unload, a lot of fishing time will be wasted. Therefore, the fishing boat first transfers the catch to the transport ship, and then transfers it through the transport ship, avoiding the long-distance round trip between the dock and the fishing area at sea.

[0003] When the transport ship and the fishing boat transfer fish at sea, it is necessary to establish a docking between the two ships. At present, the transfer of fish is generally carried out by docking, that is, the fishing boat docks on the side of the transport ship to carry out the fish lifting operation. Due to the limitations of factors such as the length of the crane boom, the fishing boat and the transport ship need to be completely close to each other to achieve this. The marine environment is extremely harsh and changeable. Most of the time, the sea is very rough and it is very easy for ships to collide with each other. Even if anti-collision facilities are added, it may still cause equipment damage, personal injury, and even dangerous situations such as the ship capsizing.

[0004] The patent with authorization announcement number CN210559008U discloses a fish transfer system, which is installed on the deck of a ship and includes at least one transfer unit. The transfer unit includes a rotating arm and a transfer assembly. The rotating arm is rotatably supported on the deck. The transfer assembly includes a hook, a first winch, a first cable, a second winch, a second cable, a fixed arm supported on the deck, a first pulley provided on the fixed arm and located above the cargo hold hatch, and a second pulley provided on the rotating arm. One end of the first cable is connected to the first winch, and the other end bypasses the first pulley to be connected to the hook. One end of the second cable is connected to the second winch, and the other end bypasses the second pulley to be connected to the hook. The rotating arm can rotate and drive the second pulley to move to the outside of the ship's side.

[0005] When the above-mentioned fish transfer system is in operation, anti-collision balls are set between the operating ship and the transport ship to prevent the two ships from colliding. Placing anti-collision balls between the two ships to increase the gap can reduce the occurrence of collisions. However, anti-collision balls have great limitations. The first is the size limit of the anti-collision balls: in order to reduce the probability of collision, it is necessary to increase the gap between the two ships as much as possible, which requires a large diameter anti-collision ball. The larger the diameter, the heavier the anti-collision ball, which not only takes up a lot of deck storage space, but is also very inconvenient to retract and release. The second is the position limit of the anti-collision ball: due to differences in size and shape, fishing boats need to lean against different positions, but the anti-collision balls of transport ships are generally placed in fixed positions, making it difficult to ensure that the two ships can be perfectly leaned against, increasing the risk of collision; the third is the influence of rolling motion: there are large differences between transport ships and fishing boats in terms of scale, displacement, center of gravity height, etc., which leads to the two ships in The amplitude and frequency of movement during rolling are completely different. The anti-collision ball cannot eliminate the mutual influence of the rolling motion between the two ships, and may even further aggravate the amplitude of the motion, causing the ship to become unstable and capsize; fourth, it is restricted by sea conditions: the fish transfer operation between transport ships and fishing boats is greatly affected by sea conditions. The siding method must be carried out in sea conditions below level three, which makes the operation window period short. The installation of anti-collision balls only reduces the intensity of the collision. Once the wind and waves are too strong, it is difficult for the ships to sidle together. Forced siding is very likely to cause collisions or even capsize. The sea is rarely calm, resulting in a short operation window period. More effective methods are urgently needed to ensure operation safety and efficiency. Summary of the invention

[0029] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] A preferred embodiment of a flexible marine fish transfer system of the present invention is as follows: Figures 1 to 7 As shown, the flexible offshore fish transfer system includes a line-throwing gun 1, a rope 2, a first winch 3, a second winch 4, a first crane 5, a second crane 6 and a fish box 7. The first winch 3 and the first crane 5 are both used to be assembled on the deck of a transport ship 11.

[0031] The rope throwing gun 1 is used to throw the rope 2 between the fishing boat 10 and the transport ship 11. The rope 2 is used to establish a flexible channel between the fishing boat 10 and the transport ship 11. The second winch 4 and the second motor are used to be assembled on the deck of the fishing boat 10. The first winch 3 and the second winch 4 are used to drive the rope 2 to move between the transport ship 11 and the fishing boat 10. The first crane 5 and the second crane 6 are used to hoist the catch box 7, and hoist the catch box 7 close to the transport ship 11 or the fishing boat 10 onto the ship. The catch box 7 is used to hold the catch caught by the fishing boat 10. The catch box 7 is a container for loading the catch. The catch box 7 can be designed in various sizes and carrying capacities according to needs to facilitate the transportation of the catch and improve the working efficiency.

[0032] The rope 2 is detachably connected to the rope throwing gun 1. After the rope 2 is connected to the rope throwing gun 1, the rope 2 is in a throwing state. The rope throwing gun 1 is thrown from one of the fishing boat 10 and the transport ship 11 to the other. The rope throwing gun 1 drives the rope 2 to connect the fishing boat 10 and the transport ship 11. After the staff disassembles the rope 2 from the rope throwing gun 1, the rope 2 can be connected to the first winch 3 and the second winch 4. At this time, the rope 2 is in a transfer state. The rope 2 can establish a flexible channel between the fishing boat 10 and the transport ship 11. The flexible channel is used to hoist the catch box 7 to transfer the catch between the transport ship 11 and the fishing boat 10.

[0033] In this embodiment, the tail end of the rope-throwing gun 1 is connected to a lightweight and flexible thin fiber rope, and the end of the fiber rope is used to connect the rope 2. After the rope-throwing gun 1 throws the fiber rope onto the target ship, the rope 2 is pulled onto the target ship. After the rope 2 and the thin fiber rope are disassembled, the rope 2 can be connected to the first winch 3 and the second winch 4 to achieve the establishment of a flexible channel.

[0034] The flexible marine fish transfer system has a detachable rope 2 connected to a rope-throwing gun 1, and the rope-throwing gun 1 is used to throw the rope 2 in a throwing state to a fishing boat 10 or a transport ship 11. After the rope 2 is connected to the first winch 3 and the second winch 4, it is in a transfer state, and a flexible channel can be established. The fish box 7 can be hoisted on the flexible channel by the first crane 5 and the second crane 6. The fish box 7 can be transferred between the fishing boat 10 and the transport ship 11 by starting the first winch 3 and the second winch 4, thereby completing the fish transfer operation; by building a flexible channel, a certain safe distance can be maintained between the fishing boat 10 and the transport ship 11 when transferring the fish, which fundamentally solves the problem of collision between ships, improves the safety of the transfer operation, can cope with the operation requirements under higher sea conditions, increases the operation window period, shortens the cycle of offshore operations, and greatly improves the efficiency of the transfer operation.

[0035] The existing transfer method can only enable ships to operate safely and closely under the third-level sea conditions, which shortens the operation window and cannot meet the actual needs. The flexible marine fish transfer system allows ships to maintain a safe distance by building a flexible channel, which can meet the operation needs under higher sea conditions, increase the operation window, shorten the offshore operation cycle, greatly improve the efficiency of transfer operations, and have significant economic benefits. At the same time, the flexible marine fish transfer system is suitable for ships of various sizes and types, and can meet the needs of marine fish transfer operations.

[0036] The wind and waves at sea are unpredictable. The traditional docking method cannot quickly separate the transport ship 11 from the fishing boat 10 to avoid sudden dangerous situations. The flexible marine fish transfer system adopts a flexible channel marine fish transfer method. On the basis of ensuring the tension of the flexible channel, the allowable load can be set. Once overloaded, it can automatically disconnect to prevent the rope 2 from pulling too much on the two ships and causing damage to the equipment, or the rope 2 from breaking and causing danger, effectively improving the ability to deal with emergencies.

[0037] Preferably, both ends of the rope 2 are connected with shackles 9 , and the rope 2 and the rope-throwing gun 1 are detachably connected via the shackles 9 .

[0038] A shackle 9 is provided on the rope 2, which can realize the rapid disassembly of the rope 2 and the rope-throwing gun 1, and can also realize the rapid disassembly between the rope 2 and the first winch 3 and the second winch 4, so as to facilitate the rapid disengagement of the flexible channel in case of sudden dangerous conditions, and prevent the rope 2 from causing excessive traction on the two ships, thereby causing damage to the equipment or the rope 2 from breaking and causing danger.

[0039] Preferably, the rope 2 is further provided with a fixed eyelet 12 , and a plurality of the fixed eyelets 12 are arranged at intervals along the length direction of the rope 2 , and the fishing box 7 is hoisted on the fixed eyelet 12 .

[0040] A plurality of fixed eyelets 12 are arranged on the rope 2, and shackles 9 can be arranged at the four corners of the catch box 7. The catch box 7 and the rope 2 can be quickly connected or disconnected through the shackles 9 and the fixed eyelets 12, thereby improving the efficiency of the transfer of the catch.

[0041] Preferably, a floating structure is also provided on the fish box 7.

[0042] When the fish box 7 is transferred on the flexible channel, the floating structure enables the fish box 7 to float on the water surface, reducing the force acting on the rope 2 forming the flexible channel and improving safety.

[0043] Preferably, the first winch 3 and the second winch 4 are both constant tension winches.

[0044] The constant tension winch can ensure that the flexible channel has a certain tension while pulling the rope 2 to transfer the fish box 7, which can prevent the flexible channel from being too loose and affecting the fish transfer efficiency, and also prevent the flexible channel from being too tight and breaking when the wind and waves are strong.

[0045] Preferably, it also includes a guide wheel 8, which is used to be fixedly assembled on the decks of the fishing boat 10 and the transport ship 11, and the rope 2 passes around the guide wheel 8 when in the transfer state.

[0046] A guide wheel 8 is installed on the deck of the fishing boat 10 and the transport ship 11 near the side, and the guide wheel 8 can limit and steer the rope 2 to prevent the rope 2 from sliding, wearing, and getting tangled on the side.

[0047] The present invention also provides a preferred embodiment of a fish catch transfer method, that is, a method for using the flexible marine fish catch transfer system in the above embodiment, comprising the following steps:

[0048] S1, before the transfer operation, the transport ship 11 and the fishing boat 10 maintain a set safety distance, connect the rope-throwing gun 1 and the rope 2, and throw the rope-throwing gun 1 from one of the transport ship 11 and the fishing boat 10 to the other;

[0049] S2, disassemble the rope-throwing gun 1 and the rope 2, connect the two ends of the rope 2 to the first winch 3 and the second winch 4 respectively, and establish a flexible passage between the fishing boat 10 and the transport ship 11;

[0050] S3, the second crane 6 is used to hoist the fish box 7 to the side of the fishing boat 10, and the fish box 7 is hoisted onto the flexible channel;

[0051] S4, start the first winch 3 and the second winch 4 to pull the rope 2 to transfer the fish box 7 to the side of the transport ship 11, and start the first crane 5 to hoist the fish box 7 to the transport ship 11;

[0052] S5, repeat the above steps to complete the transfer of fish catch.

[0053] In step S1, the safety distance between the transport ship 11 and the fishing boat 10 can be adjusted according to the size of the wind and waves at sea, the size and type of the transport ship 11 and the fishing boat 10. The flexible channel established by the rope 2 can be suitable for the transfer of fish catches at different safety distances, meeting the needs of marine fish catch transfer operations, and has a wide range of applications.

[0054] In step S2, when constructing the flexible passage, shackles 9 are provided at both ends of the rope 2 to realize quick connection and disassembly between the rope 2 and the rope throwing gun 1, the first winch 3, and the second winch 4. When establishing the flexible passage, the rope 2 is passed around the guide wheels 8 on the side of the fishing boat 10 and the transport ship 11 to prevent the rope 2 from sliding and wearing on the side and getting tangled.

[0055] In step S3, when hoisting and transferring the fish box 7, you can choose to fill the fish box 7 first and then hoist it onto the fixed eye 12 of the rope 2, or you can first hoist the empty fish box 7 onto the rope 2 and then load the fish.

[0056] In step S4, the first crane 5 is started to lift the fish box 7 to the transport ship 11, and then unloaded. The unloaded fish box 7 can be transferred to the fishing boat 10 through the flexible channel to perform repeated fish transfer.

[0057] In some other embodiments, such as Figure 7 As shown, the number of winches, guide wheels 8, rope-throwing guns 1, and ropes 2 can be increased, and two flexible channels can be established between the transport ship 11 and the fishing boat 10 at the same time. One flexible channel is used to transfer the fish box 7 loaded with fish, and the other flexible channel is used to transfer the empty fish box 7 to the fishing boat 10. The two flexible channels are operated simultaneously to improve the transfer efficiency.

[0058] Preferably, in step S4, when transferring the fish box 7, the bows of the fishing boat 10 and the transport ship 11 are both facing the direction of wind and waves, and the fishing boat 10 and the transport ship 11 sail in the same direction.

[0059] The bows of the fishing boat 10 and the transport ship 11 face the direction of the wind and waves, which can reduce the rolling and drifting of the ships. The fishing boat 10 and the transport ship 11 sail in the same direction, and when the water flow is too strong, the positions of the fishing boat 10 and the transport ship 11 can be kept relatively stable.

[0060] In summary, the embodiments of the present invention provide a flexible marine fish transfer system and a fish transfer method, which uses a rope that can be detachably connected to a rope-throwing gun, and uses the rope-throwing gun to throw the rope in a throwing state to a fishing boat or a transport ship. After the rope is connected to the first winch and the second winch, it is in a transfer state, and a flexible channel can be established. The fish box can be hoisted on the flexible channel by the first crane and the second crane, and the fish box can be transferred between the fishing boat and the transport ship by starting the first winch and the second winch, thereby completing the fish transfer operation; by building a flexible channel, a certain safe distance can be maintained between the fishing boat and the transport ship when transferring the fish, which fundamentally solves the problem of collision between ships, improves the safety of the transfer operation, can cope with the operation requirements under higher sea conditions, increases the operation window period, shortens the cycle of offshore operations, and greatly improves the efficiency of the transfer operation.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
