Description

Technical Field

[0001] The present invention relates to the technical field of fishing vessels, in particular to a trawler and a fishing method thereof. Background Art

[0002] At present, the main fishing methods of trawlers are traditional plate trawl and continuous pump-suction outrigger crossbar trawl. However, for the traditional plate trawl fishing method, this fishing method requires frequent raising and lowering of the net, that is, after the net is lowered to catch fish, the net needs to be pulled to the fishing boat to pour out the fish, and then the net needs to be lowered again to catch fish, and this cycle is repeated. Therefore, the operation time of raising and lowering the net takes up a long time of the entire fishing time, which reduces the effective trawl time and affects the fishing efficiency. Secondly, the frequent raising and lowering of the net leads to a higher workload for the operators. Moreover, the frequent use of fishing equipment not only reduces its lifespan, but also consumes energy, which is neither environmentally friendly nor economical. In addition, in this fishing method, all the catches are piled up in the net and are easily crushed, which reduces the quality of the raw fish.

[0003] In order to address the shortcomings of the above-mentioned traditional net trawling method, continuous pump-suction crossbar trawling technology has developed rapidly in recent years. This involves setting outriggers on the port and starboard sides of the fishing vessel, towing the net through the outriggers, and performing pumping operations while towing to suck the fish caught in the net onto the fishing vessel. This fishing method does not require frequent lifting and lowering of the net, which greatly increases the fishing time and ensures the product quality of the raw fish. However, in actual use, other more serious problems have been discovered: First, the time required to raise / lower the net is long. It takes almost 10 hours to set the net on one side, and almost a whole day to set the net on both sides. The continuous long-term operation makes the crew very tired. Second, there are many winches involved in the operation, as many as 16, and some ships even have 20. This brings challenges to the coordinated operation of the winches and also brings a large amount of equipment and supporting costs to the ship construction. Moreover, the outriggers on both sides of the fishing vessel tow the net, and their stress state will have a certain impact on the stability of the ship, causing potential The safety risk is that when the ship turns, in order to prevent the two nets towed in the stern area from colliding / tangling together, the net position needs to be adjusted, which brings difficulties and challenges to the operation; most importantly, there are many ropes and hoses entering the water from the ship, sometimes as many as 10, and if the order is wrong, it has to be started over again, which makes the operation complicated and difficult. For Chinese fishermen, it is not easy to adapt to and master this operation method. Too many ropes will also cause potential harm to protected animals in the sea, and too many ropes exposed at sea will also cause potential harm to protected birds at sea. Summary of the Invention

[0064] See also Figures 1 to 12 It should be noted that the diagrams provided in this embodiment are merely schematic illustrations of the basic concept of the present invention. Therefore, the diagrams only show components relevant to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be arbitrarily changed, and the component layout may also be more complex.

[0065] On the one hand, the present invention provides a trawler, specifically Figures 1 to 3 As shown, the trawler includes two trawling winches 11, two first guide components 110, a net reel 12, a tail unloading winch 21, a tail guide component 22, and a hose winch 13. The two trawling winches 11 are respectively arranged on the left and right sides of the first deck 10, and each trawling winch 11 is wound with a first rope 111; the two first guide components 110 are respectively arranged on the left and right sides of the tail area of ​​the trawler, and each first rope 111 passes through a first guide component during fishing operations. 110 is connected to a net plate 100, that is, the first guide member 110 is used to guide the first rope 111 passed through; the net reel 12 is set on the first deck 10, and the net reel 12 can retract and store the fishing net 120; the tail unloading winch 21 is set on the second deck 20, and the tail unloading winch 21 is wound with a second rope 211, and the second rope 211 can be used to hook with the fishing net 120 on the net reel 12 to pull the fishing net 120 out of the net reel 12. It should be noted that in this embodiment In the embodiment, the height of the second deck 20 is higher than that of the first deck 10; the tail guide component 22 is provided at the tail end of the trawler, and the second rope 211 passes through the tail guide component 22 and extends to the first deck 10 and is hooked with the fishing net 120 during fishing operations. The tail guide component 22 is used to guide the second rope 211; the hose winch 13 is provided on the first deck 10, and a first hose 131 is wound around the hose winch 13. When fishing and setting the net, the first end of the first hose 131 is used to The second end of the first hose 131 is connected to the fishing net 120 and is used to be connected to a pumping device (not shown in the figure); a net position meter 121 is provided at the net mouth of the fishing net 120, and a net position meter winch 14 is also provided on the trawler. The net position meter winch 14 is arranged on the first deck 10 of the trawler and is located in the stern area of ​​the trawler. A net position meter cable 141 is wound around the net position meter winch 14. The net position meter cable 141 is used to provide power and signal transmission to the net position meter (121).

[0066] When the trawler of the present invention is used for fishing, the first ropes 111 on the two trawling winches 11 are first pulled out, so that each first rope 111 passes through a first guide member 110 and is connected to a net plate 100, that is, Figure 3As shown, the first rope 111 on the trawler winch 11 on the left side of the trawler passes through the first guide component 110 on the left side of the stern area and is connected to a net plate 100. The first rope 111 on the trawler winch 11 on the right side of the trawler passes through the first guide component 110 on the right side of the stern area and is connected to a net plate 100. After the first rope 111 is connected to the net plate 100, there is no need to disassemble it later; then the second rope 211 on the tail unloading winch 21 is pulled out, passed through (bypassed) the tail guide component 22 set at the tail end of the trawler, and then extended from the second deck 20 to the first deck 10 and The fishing net 120 is hooked with the fishing net 120 on the net reel 12, and then the tail unloading winch 21 is controlled to pull the fishing net 120 toward the tail end of the trawler, so as to pull the fishing net 120 from the net reel 12 to the first deck 10. At the same time, that is, while pulling the fishing net 120, the first hose 131 on the hose winch 13 is also pulled out, and then the released fishing net 120 is connected to the first hose 131. When the net mouth of the fishing net 120 is pulled to the stern of the trawler (before the stern slide) (at this time, the main body of the fishing net has been pulled into the sea water), the left and right sides of the net mouth of the fishing net 120 are respectively connected to the two net plates 100 mentioned above (as shown in FIG. Figure 4 and Figure 5 As shown), the net position finder cable 141 pulled out from the net position finder cable winch 14 is connected to the net position finder 121 of the network port, and then the trawl winch 11, the hose winch 13 and the net position finder cable winch 14 are controlled to release the first rope 111, the first hose 131 and the net position finder cable 141 respectively, so as to lower the fishing net 120 into the target water depth area. Then, during the pumping fishing process of the trawler, the fishing net 120 is towed by the trawl winch 11 and the net plate 100, and the pumping device is used to perform a pumping operation to pump the fish in the fishing net onto the fishing vessel.

[0067] Therefore, compared to the prior art continuous pump-suction outrigger crossbar trawling method, the trawler provided by the present invention is simple and safe to operate during net-setting fishing operations, with convenient net release and a total net-setting time of approximately two hours. This significantly improves net-setting efficiency and reduces operator labor intensity, saving significant time during pump-suction fishing, thereby improving fishing efficiency. Furthermore, the number of winches involved in net-setting operations (only four winches) is relatively small, simplifying operation and reducing manufacturing costs. Furthermore, the number of exposed ropes is relatively small (only four ropes: two first ropes, a net position finder cable, and a first hose). Consequently, the trawler significantly reduces the potential risk of harm to protected marine animals and birds during fishing operations.

[0068] Specifically, the hose winch 13 is preferably a constant-tension hose winch. That is, when the trawl winch 11 releases the first rope 111 to lower the fishing net 120 to the target water depth, the hose winch 13 activates constant-tension mode, and the first hose 131 on the hose winch 13 automatically releases according to the length of the first rope 111 released, making operation simple and convenient. Preferably, the trawl winch 11 is also a constant-tension winch. This allows the first rope 111 to automatically retract and extend according to external environmental forces through a constant-tension system when the trawl winch 11 tows the fishing net 120 for fishing operations, relieving sudden external forces and ensuring safer and more stable towing of the fishing net. Specifically, in this embodiment, the net finder winch 14 is also a constant-tension net finder winch. Therefore, when the first rope 111 is released to lower the fishing net to the target water depth, the net finder winch 14 activates constant-tension mode, and the net finder cable 141 attached thereto automatically releases as the first rope 111 is released. Specifically, to prevent wear and tear on the net position finder cable caused by contact between the net displacement cable 141 and the hull of the fishing vessel, preferably, in this embodiment, a cable pulley 142 is provided at the rear end of the trawler. The net position finder cable 141 passes through the cable pulley 142 and is connected to the net position finder 121. Of course, in other optional embodiments, those skilled in the art may also choose to install a wireless net position finder at the network port of the fishing net 120. When using a wireless net position finder, there is no need to install a net position finder winch.

[0069] In this embodiment, the net finder winch 14 is positioned on the first deck 10 (the trawl deck) of the trawler, at its lowest point relative to the water surface. Furthermore, it is located in the stern area of ​​the trawler. This design ensures that the net finder cable 141 quickly enters the water, minimizing the length of cable remaining in the air. This significantly reduces the risk to airborne seabirds and makes it easier for fishermen to deploy bird-scare devices. It should be noted that in this embodiment, the first deck 10 is the trawl deck of the trawler.

[0070] Specifically, in this embodiment, the drum of the hose winch 13 is hollow and has a through hole defined in its radial direction. The second end of the first hose 131 passes through the through hole and then extends from an axial end of the drum to connect to the pumping device. This is prior art and will not be further described here.

[0071] Preferably, Figure 1As shown, in this embodiment, the tail guide component 22 includes a fixing frame 221 and a guide pulley 220, wherein the fixing frame 221 is fixedly installed at the tail end of the trawler, and the first end of the fixing frame 221 extends to the rear of the stern away from the stern of the trawler, and the guide pulley 220 is rotatably installed at the first end of the fixing frame 221. Through this structural design, the structure is simple and the service life is long. Figure 2 As shown, in this embodiment, the fixing frame 221 is A-shaped.

[0072] Further, such as Figure 3 and Figure 5 As shown, in this embodiment, the first guide component 110 is a trawl pulley, and it should be noted that, as a preference, in order for the trawl winch 11 to better recover the first rope 111, the setting position of the first guide component 110 needs to satisfy the angle between the rope-out direction of the first rope 111 and the drum of the trawl winch 11 meets relevant requirements.

[0073] Further, such as Figure 1 and Figure 3As shown, in this embodiment, the hose winch 13 is arranged in the stern area of ​​the trawler, and correspondingly, a hose storage winch 23 is also provided on the trawler. The hose storage winch 23 is arranged on the second deck 20, and a second hose 231 is wound around the hose storage winch 23. When performing fishing and netting operations, the stern unloading winch 21 can not only pull the fishing net 120, but also pull the second hose 231 on the hose storage winch 23, and pull the second hose 231 from the second deck 20 to the first deck 10, and drop it on the fishing net 120. , and then connect the released fishing net 120 with the second hose 231, that is, one end of the second hose 231 is connected to the net bag of the fishing net 120, and the tube body of the second hose 231 is connected and fixed to the net body (surface) of the fishing net 120 to fix the second hose 231 and prevent the second hose 231 from swinging back and forth in the water. Then, after the second hose 231 is completely released from the hose storage winch 23, the first end of the first hose 131 on the hose winch 13 is connected to the other end of the second hose 231 and communicated. This structural design can avoid the disadvantages of designing only one hose winch 13. That is, when only one hose winch 13 is designed, if the hose winch 13 is set at the stern, the first hose 131 on the hose winch 13 will inevitably be bent on the deck when connected to the fishing net 120. Since the hose material used in pump-suction fishing is relatively hard and has a large diameter, the bending operation is very difficult to perform and the hose is easily damaged. If the hose winch 13 is set in an area far away from the stern (for example, at the same position as the net winder), after the fishing net and the hose are lowered into the seawater, when the fishing net is towed for fishing pumping operations, a large part of the first hose 131 will remain on the first deck 10. During the pump-suction fishing operation, the first hose remaining on the first deck 10 is likely to collide with other equipment on the first deck and be damaged, and there is also a safety hazard. In this embodiment, the hose winch 13 is arranged at the stern and a hose storage winch 23 is arranged on the second deck. The second hose 231 on the hose storage winch 23 is connected to the fishing net. After the second hose 231 is fully released and the other end (end) of the second hose is pulled to the stern area, the end of the second hose is connected to the first end of the first hose 131 on the hose winch 13, thereby ensuring that the hose and the fishing net are easily connected while avoiding leaving a long hose on the deck. The operation is convenient, simple and safe.

[0074] Preferably, in this embodiment, the length of the second hose 231 stored on the hose storage winch 23 matches the length of the fishing net 120. Through this design, when the fishing net mouth (the end of the second hose) is released to the stern, the end of the second hose 231 is also at the stern, that is, the position of the hose winch 13, thereby facilitating the connection between the first hose 131 and the second hose 231.

[0075] Preferably, Figure 1 As shown, in this embodiment, the position of the hose storage winch 23 is farther from the stern of the trawler than the position of the net reel 12, that is, the hose storage winch 23 is arranged above and behind the net reel 23. Through this arrangement design, the connection operation of the second hose 231 and the fishing net 120 is further facilitated.

[0076] Further, such as Figure 1 and Figure 11 As shown, in this embodiment, a platform frame 40 is provided at the stern area of ​​the trawler, and at least one auxiliary pulley 41 is provided on the platform frame 40. During fishing operations (i.e., after the fishing net 120 is towed), the second rope 211 of the tail unloading winch 21 can be passed through the auxiliary pulley 41 to assist in other operations on the first deck. For example, when the position of the fishing net or the first hose placed on the first deck 10 needs to be adjusted, or when a sinker needs to be connected to the fishing net, since the fishing net, the first hose, the sinker, etc. are all relatively heavy and are measured in tonnage, the second rope 211 of the tail unloading winch 21 can be passed through the auxiliary pulley 41 to connect to the object to be adjusted, and then the position of the object can be adjusted by operating the tail unloading winch 21.

[0077] Further, such as Figure 1 and Figure 11 As shown, the trawler is also equipped with at least one auxiliary winch 31, around which a third rope 311 is wound. Specifically, the auxiliary winch 31 is mounted on a work platform 30, which is higher than the second deck 20. The auxiliary winch 31 is positioned so that the delivery direction of the third rope 311 is tangent to the stern slide of the trawler. With this design, when encountering sporadic fish and the continuous pumping method of the net trawling is not necessary, the trawler can also use the traditional net trawling method for fishing. That is, when using the traditional net trawling method for fishing, the net-releasing operation can omit the connection between the first hose and the second hose, the connection between the second hose and the net, and the connection of the net position meter cable (using a wireless net position meter), resulting in a shorter single net-releasing time.

[0078] When the trawler is fishing by using a conventional trawling method, after the trawling is completed, the third rope 311 of the auxiliary winch 31 is connected to the fishing net (such as Figure 11As shown), the auxiliary winch 31 is then controlled to drag the net bag filled with fish from the water onto the first deck 10. The second rope 211 of the tail unloading winch 21 is then passed through the auxiliary pulley 41 and connected to the net bag to lift the net bag and dump the fish in the net bag. Of course, in this embodiment, the third rope 311 on the auxiliary winch 31 can also be passed through the auxiliary pulley 41 to assist other operations on the first deck 10 (such as Figure 1 Specifically, in this embodiment, the auxiliary winch 31 is a Gilson winch.

[0079] Compared to the conventional continuous pump-suction outrigger crossbar trawling operation, which requires the connection of the net to the hose, the net to the crossbar, the crossbar to the trawl wire rope, the hose to the crossbar, and the hose to the hose, the trawler provided by the present invention is much simpler to operate, the net is easily released, and the entire net-releasing time can be basically controlled to about two hours, which greatly improves the net-releasing efficiency, saves a lot of time for pump-suction fishing, and improves fishing efficiency. In addition, the number of winch equipment involved in the net-releasing operation is relatively small, which simplifies the operation and reduces the manufacturing cost. In addition, the number of exposed ropes is relatively small (only four ropes, two first ropes, a net position meter cable, and a first hose). Therefore, the trawler greatly reduces the potential risk of harm to protected marine animals and protected birds during fishing operations. At the same time, the trawler provided by the present invention can also perform traditional net trawling. With two fishing methods on one vessel, it can be flexibly used according to specific needs and has strong applicability.

[0080] like Figure 12 As shown, another aspect of the present invention further provides a fishing method using the above-mentioned trawler, comprising the following steps: S1, pulling out the first ropes on the two trawler winches from the trawler winches, passing the first ropes through a first guide component, and then connecting them to a net plate;

[0081] Specific as Figure 3 As shown, the first rope 111 on the trawl winch 11 located on the left side of the trawler passes through the first guide component 110 located on the left side of the stern area and is connected to a mesh plate 100. The first rope 111 on the trawl winch 11 located on the right side of the trawler passes through the first guide component 110 located on the right side of the stern area and is connected to a mesh plate 100. After the first rope 111 is connected to the mesh plate 100, there is no need to disassemble it later.

[0082] S2. Pulling a second rope from the tail unloading winch, passing it through a tail guide member provided at the tail end of the trawler, and hooking it with the fishing net on the net reel, thereby pulling the fishing net from the net reel onto the first deck; pulling a second hose from the hose storage winch from the hose storage winch until it falls above the fishing net; and connecting the second hose to the fishing net when releasing the fishing net and the second hose;

[0083] S3. When the opening of the fishing net is pulled to the stern of the trawler, the left and right sides of the opening of the fishing net are connected to the net plates respectively; simultaneously, the first hose is pulled out from the hose winch to the first deck and connected to the second hose; the net position meter cable pulled out from the net position meter cable winch is connected to the net position meter at the opening of the fishing net;

[0084] Specifically, in this step, the upper and lower fork steels on the fishing net 120 are switched off from the net reel 10 and connected to the net plate 100 .

[0085] S4, controlling the trawl winch, the hose winch, and the net position finder cable winch to release the first rope, the first hose, and the net position finder cable, respectively, to lower the fishing net into the target water depth area;

[0086] Specifically, in this step, the aforementioned hose winch 13 and net finder cable winch 14 are both constant tension winches. That is, when the trawl winch 11 releases the first rope 111 to lower the fishing net 120 to the target water depth, the hose winch 13 and the net finder cable winch 14 activate a constant tension mode. The first hose 131 on the hose winch 13 and the net finder cable 141 on the net finder cable winch 14 automatically release according to the length of the first rope 111 released. Specifically, the trawl winch 11 is also a constant tension winch, so that when the trawl winch 11 tows the fishing net 120 for fishing operations, the first rope 111 can be automatically retracted and released through the constant tension system according to external environmental forces, releasing external sudden force, thereby ensuring safer and more stable towing of the fishing net.

[0087] S5. Performing a trawling operation by the trawling winch and performing a continuous pumping operation by the pumping device.

[0088] Compared with the prior art, the fishing method based on the above-mentioned trawler of the present invention adopts the traditional net trawling method that the crew is accustomed to, and then combines it with a continuous pumping fishing method, that is, the continuous pumping fishing method of the net trawling is not only simple and safe to operate, convenient to release the fishing net, and less winch equipment involved in the net releasing operation (only 4 winch equipment), low manufacturing cost, but also does not require frequent lifting and lowering of the fishing net, greatly improving the fishing efficiency and ensuring the quality of the fish; at the same time, the trawler has fewer ropes exposed during fishing operations (only four ropes, two first ropes, a net position meter cable and a first hose), so that the trawler also greatly reduces the potential risk of harm to protected animals in the sea and the potential risk of harm to protected birds in the sea during fishing operations.

[0089] In summary, the trawler and its fishing method of the present invention have a reasonable configuration of fishing gear and equipment, and a simple and convenient fishing method. It uses the traditional plate trawling method that crew members are accustomed to, and then combines it with a continuous pump-suction fishing method to catch fish. That is, fishing is carried out by using the plate trawling continuous pump-suction fishing method. The net-releasing operation is simple, the fishing net is easy to release, and the number of winch equipment involved in the net-releasing operation is small. While the manufacturing cost is low, there is no need to frequently raise and lower the fishing net when catching fish, thus ensuring the quality of the fish and greatly improving the fishing efficiency. This solves the problems of the prior art continuous pump-suction outrigger crossbar trawling method, which is cumbersome and difficult to release the net, takes a long time to release the net, requires multiple winch equipment, and has a large number of exposed ropes. At the same time, the trawler provided by the present invention can also perform traditional plate trawling fishing. With two fishing methods on one vessel, one can flexibly use them according to specific needs and has strong applicability. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial utilization value.
