Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of freshwater aquaculture, in particular to a cultured aquatic product fishing system and a fishing method. BACKGROUND

[0002] Aquatic products are common food materials on the dining table. With the development of production technology, due to the fast breeding speed of artificial breeding and the ability to choose the number and time of fishing, the market supply of freshwater fish has basically changed from natural fishing to artificial breeding. At present, the cultured aquatic products are usually caught by purse seining, that is, the fishing net is thrown or towed while driving the water surface carrier, so as to enclose a specific water area, then the fishing net is retracted to limit the movement of aquatic products, and then the aquatic products are collected and transported by net cages and other fishing tools, that is, the fishing of cultured aquatic products is completed. In the process of purse seining, the fishing net usually needs to be set close to the edge of the culture pond to improve the fishing amount, which requires high skill of carrier and fishing net operation, and usually needs to be operated by experienced personnel, and the net throwing and driving need to be operated manually, which increases the labor cost.

[0003] The patent document with publication number CN113615650B discloses a large-scale aquaculture facility fish high-efficiency fishing method, which includes the following steps: step one, installing main and auxiliary net lifting machines on the left and right sides of the fence platform or truss net cage, and retracting, expanding and towing the net by moving the main and auxiliary net lifting machines; step two, guiding the fish into the net body and into the bag net by towing the net; step three, adjusting the mesh of the bag net according to the size of the fish body; step four, quickly opening or closing the bag net cover; step five, quickly harvesting the fishing fish in the bag net; and step six, retracting the net. The above technical solution can drive the fish into the bag net by the main and auxiliary net lifting machines, which saves the step of purse seining and reduces the labor cost, but it can only fish in the fixed water area enclosed by the net, and cannot freely fish in the peripheral water area, which has obvious limitations and is not suitable for large-scale application. SUMMARY

[0004] In order to solve the above problems, the present application provides a cultured aquatic product fishing system, which can reduce the labor demand in the process of purse seining, is simple to operate, has low experience requirement for the user, and is suitable for various water areas, which can improve the fishing efficiency.

[0005] In order to achieve the above effects, the present application adopts the following technical solutions:

[0007] The traction rope is arranged on the upper side of the net body and extends outward from the traction end of the fishing net, so that the traction end of the fishing net can be moved under the driving of the traction rope. When the traction rope is detachably connected with the guide mechanisms around the edge of the breeding pool, the traction end of the fishing net can be moved towards the nearest guide mechanism under the driving of the traction mechanism. Since the guide mechanisms are detachably connected with the traction rope, when the traction end of the fishing net reaches the nearest first guide mechanism, the connection between the traction rope and the guide mechanism can be released, so that the traction end of the fishing net can continue to move towards the nearest second guide mechanism. According to the above method, the traction end of the fishing net can pass through the positions of all the guide mechanisms, that is, the traction end of the fishing net can move around the edge of the breeding pool, so that most of the aquatic products in the breeding pool can be enclosed in the fishing area formed by the fishing net. Then, the aquatic products in the fishing area can be driven into the fishing box, so that the fishing of the aquatic products can be realized. The above scheme can convert the operations such as driving and netting in the purse seine fishing process, which need human input and have high requirements on proficiency, into mechanical automatic operations. The traction mechanism and the traction rope can be used to realize the purse seine step, so that the human cost can be greatly reduced. Moreover, the size of the fishing area enclosed by the fishing net can be adjusted according to the arrangement mode of the traction mechanism, so that the application range is wide.

[0018] S2, the traction mechanism is started, the second end of the fishing net moves towards the guide mechanism A1, when the second end of the fishing net reaches the guide mechanism A1, the connection between the traction rope and the guide mechanism A1 is released, the fishing net passes through the position of the guide mechanism A1 and continues to move towards the guide mechanism A2, when the fishing net reaches the guide mechanism A2, the connection between the traction rope and the guide mechanism A2 is released, the fishing net passes through the position of the guide mechanism A2 and continues to move towards the guide mechanism A3, the above steps are repeated until the fishing net passes through the guide mechanism An-1 and continues to move towards the guide mechanism An, when the fishing net approaches the guide mechanism An, the connection between the traction rope and the guide mechanism An is released, the fishing net passes through the position of the guide mechanism An and moves towards the second side of the lifting mechanism;

[0019] S3, when the fishing net reaches the second side of the lifting mechanism, the traction mechanism continues to operate, so that the fishing area formed by the fishing net gradually decreases, the movable tank wall of the fishing tank is moved, the aquatic product inlet and outlet are opened, and the aquatic products in the fishing area are driven into the fishing tank;

[0020] S4, the movable tank wall of the fishing tank is moved, the aquatic product inlet and outlet are closed, the fishing tank is lifted out of the farming pond, and one fishing of the farming aquatic product is completed.

[0021] In summary, the application scheme can achieve the following beneficial effects:

[0033] As Figure 1 shown, the present embodiment provides a breeding aquaculture system, which comprises a loading mechanism 1 arranged based on a breeding pond 6, a plurality of guide mechanisms 2, a purse seine mechanism 3, a traction mechanism 4 and a lifting mechanism 5; the loading mechanism 1 is positioned and arranged at the edge of the breeding pond, used for loading aquatic products and transferring them outside the breeding pond; the plurality of guide mechanisms 2 are arranged in sequence around the edge of the breeding pond, used for guiding the movement of the purse seine mechanism 3; the purse seine mechanism comprises a purse seine 32, which is used to enclose the water area in the breeding pond and concentrate the aquatic products therein by shrinking the enclosed water area, and finally drive them into the loading mechanism, and the purse seine is provided with a traction rope 323; the traction mechanism 4 is in driving connection with the traction rope 323 of the purse seine 32 when in use, used to drive the movement of the purse seine 32; the lifting mechanism 5 is arranged at a position close to the loading mechanism, used to lift and place the loading mechanism 1.

[0034] As Figure 4As shown, the loading mechanism 1 includes a fishing box 11 and a positioning rack 12 for placing the fishing box 11, the positioning rack includes three panels surrounding an inner pool area with an opening, the fishing box can be put into or lifted out of the inner pool area in the vertical direction, the upper edge of the fishing box forms a convex structure capable of lapping over the panels to fix the fishing box, the opening direction of the positioning rack corresponds to the direction of the aquatic product outlet of the fishing box, so that the aquatic products can enter the fishing box through the opening of the positioning rack; the fishing box is provided with a movable box wall 111, when the movable box wall is moved upwards, one side of the fishing box forms an open aquatic product outlet, when the movable box wall is moved downwards to reset, the aquatic product outlet is closed, the upper side of the movable box wall is also provided with a lifting bracket 112, the lifting bracket 112 is used to provide a connection site for the lifting mechanism 5, facilitating the movement of the fishing box. In further embodiments, the panels include two fixed panels 121 arranged in parallel and a movable panel 122 arranged vertically compared to the fixed panels, the movable panel 122 can move along the extension direction of the fixed panels to change the size of the inner pool area, and the movable panel can also be separated or installed on the fishing rack in the vertical direction.

[0035] The fishing net 32 includes a net body 321, a weight 322 arranged on the lower side of the net body, and a traction rope 323 arranged on the upper side of the net body, a part of the traction rope 323 extends outward from the traction end of the fishing net, in use, the fixed end of the fishing net is anchored by an anchor rod on one side of the fishing box 11, the traction end is connected to the traction mechanism 4 through the traction rope, and the traction end can be controlled to move under the driving of the traction rope; the traction mechanism 4 has a winding device, after the traction rope 323 is connected with the winding device, the traction mechanism 4 can provide traction to the traction rope by starting the winding device, so that the traction end of the fishing net is subjected to traction and moves. In some embodiments, the winding device can be used in combination with a variable frequency controller to control the winding speed, so that the moving speed of the traction end of the fishing net is relatively stable, which can ensure the working efficiency and avoid damage to the structure of the fishing net caused by too fast winding speed. In some embodiments, the winding device can also be used in combination with a wireless control system to facilitate the control of the traction process. In some embodiments, the purse seine mechanism can also be provided with a carrier 31 to assist in fishing, the carrier is provided with a second traction mechanism, the traction rope is connected to the second traction mechanism after being led out from the traction end of the fishing net, and the traction mechanism 4 is connected with the carrier 31, when the traction mechanism 4 is started and performs the purse seine work (as shown in parts a and b of Figure 2 , the movement of the carrier is directly guided, and the movement of the fishing net is indirectly guided through the carrier, at this time, the second traction mechanism is in the closed state, when the carrier reaches the specified terminal point, the second traction mechanism is started, the water area surrounded by the fishing net is shrunk, and the fishing net is gradually transferred above the carrier (as shown in part c of Figure 2When the transportation of the fishing net is completed, the anchoring rod is released from the fixed end of the fishing net, and the fishing net is retracted into the carrier and lifted out of the breeding pool by the lifting mechanism.

[0036] The guiding mechanism is arranged around the edge of the breeding pool 6 to guide the movement of the leading end of the fishing net, so that the leading end of the fishing net passes through the guiding mechanisms arranged in sequence, for example, in the embodiment shown in Figure 1 four guiding mechanisms A1, A2, A3 and A4 are arranged. When fishing, the leading end of the fishing net will reach the guiding mechanisms A1-A4 in sequence. When reaching a guiding mechanism, the guiding mechanism is disconnected from the leading rope, so that the fishing net will not be entangled with the guiding mechanism when passing through the guiding mechanism, and the guiding mechanism will not restrict the movement of the fishing net. In the subsequent steps, the fishing net can shrink to form a fishing area, which is ready for the next fishing operation. In the case of guiding mechanisms arranged along the edge of the breeding pool, the leading end of the fishing net can move around the edge of the breeding pool, thereby trapping most of the standard-sized aquatic products in the breeding pool. The above-mentioned standard size refers to the size of the aquatic products that have grown to a certain extent and cannot pass through the mesh of the fishing net. During the fishing process, some fry will be filtered out to ensure the continuous output of the water area. Similarly, the fishing net 11 and the positioning frame 12 in the loading mechanism 1 should also have a certain size of mesh structure.

[0037] The present embodiment provides a method for breeding and fishing aquatic products based on the above-mentioned breeding and fishing system. Figures 1 to 3 For example, the specific operation is as follows:

[0038] S1, guiding mechanisms A1, A2, A3 and A4 are arranged around the edge of the breeding pool, the fixed end of the fishing net is positioned in the breeding pool by the anchoring rod on the first side of the loading mechanism, and the leading rope extending outward from the leading end of the fishing net is connected to the leading mechanism arranged on the second side of the loading mechanism. The leading rope is connected to the guiding mechanisms A1, A2, A3 and A4 in sequence around the breeding pool, and the state of the fishing system is as shown in Figure 1 ;

[0039] S2, start the leading mechanism to move the leading end of the fishing net to the guiding mechanism A1, when the second end of the fishing net reaches the guiding mechanism A1, disconnect the leading rope from the guiding mechanism A1, so that the fishing net passes through the position of the guiding mechanism A1, and continues to move to the guiding mechanism A2, at this time the state of the fishing system is as shown in Figure 2As shown in section a; when the fishing net reaches guide mechanism A2, the connection between the traction rope and guide mechanism A2 is released, allowing the fishing net to pass through the position of guide mechanism A2 and continue moving towards guide mechanism A3; when the fishing net reaches guide mechanism A3, the connection between the traction rope and guide mechanism A3 is released, allowing the fishing net to pass through the position of guide mechanism A3 and continue moving towards guide mechanism A4. At this time, the state of the fishing system is as follows. Figure 2 As shown in section b; when the fishing net approaches the guide mechanism A4, the connection between the traction rope and the guide mechanism A4 is released, allowing the fishing net to pass through the location of the guide mechanism A4 and move towards the second side of the loading mechanism. At this time, the state of the fishing system is as follows. Figure 2 As shown in section c;

[0040] S3. After the fishing net reaches the second side of the loading mechanism, the traction mechanism continues to operate, causing the fishing area formed by the fishing net to gradually decrease. At this time, the state of the fishing system is as follows: Figure 2 As shown in sections d and e, the movable box wall of the fishing box is moved to open the aquatic product inlet and outlet, and the aquatic products in the fishing area are driven into the fishing box;

[0041] S4. The movable box wall of the mobile fishing box closes the aquatic product inlet and outlet, and the fishing box is transported out of the aquaculture pond, thus completing one harvest of aquatic products.

[0042] Furthermore, when the amount of aquatic products intercepted in the fishing area exceeds the required catch, it can be determined according to... Figure 4 The structure shown opens the movable panel of the positioning frame, allowing the remaining aquatic products in the fishing area to exit freely. When the quantity of aquatic products to be caught in the fishing area exceeds the single loading capacity of the fishing box, it can be adjusted according to... Figure 4 The movable side panel of the structure shown drives the aquatic products in the inner pool area back into the fishing area formed by the fishing net. Then, the unloaded fishing box is reset on the positioning frame. The movable side panel is then separated from the positioning frame vertically and reset, and the second loading can be carried out. The above steps can be repeated multiple times until the catch demand is met.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
