Description

Technical Field

[0001] The present invention relates to the technical field of ocean ranch fishing equipment, and specifically to a fishing device for ocean ranching. Background Art

[0002] In ocean ranching, fixed-point fishing is usually adopted as one of the fishing methods. Compared with traditional extensive fishing, this method pays more attention to the fishing of target species and reduces the impact on other marine organisms or the ecological environment.

[0003] In ocean ranching, it is usually necessary to use bait to attract fry into the fishing area; such as shrimps, planktonic fish or planktonic algae, etc., which are the natural foods of many fry. Using natural plankton as bait can effectively attract target fish; amino acids and peptides: these are common chemical components in fish food and can trigger the appetite response of fish.

[0004] In the fish farming areas of ocean ranching, feed is usually put in. The feed that is not eaten by fish and fish excrement will also enter the water body, increasing the nutrients such as nitrogen and phosphorus in the water and providing rich growth conditions for seaweed. Therefore, when fish swim in this water area, they are easily attached with seaweed. After the fish enter the fishing device, the fishing device is not immediately taken out of the water, and the seaweed attached to the caught fish cannot be processed in time. The seaweed always adheres to the caught fish, which is likely to affect the appearance and quality of the caught fish. Summary of the Invention

[0029] The present invention has the following beneficial effects:

[0030] (1) With the plurality of brushes provided in the present invention, during the process of the device fishing for fish, when the fish in the trapping box enter the through box through the cylinder, their bodies will continuously contact the bristles of the plurality of long brushes, so that the plurality of long brushes can clean the seaweed attached to the fish. In this way, the seaweed attached to the fish can be cleaned, reducing the amount of seaweed attached to the caught fish, preventing the need to clean a large amount of seaweed attached to the fish after they are caught ashore, thus delaying the time for subsequent processing of the caught fish, and at the same time preventing the fish caught in the fishing cage from being attached with a large amount of seaweed for too long, and the decomposition of seaweed and other organic matters affecting the quality of the fish meat.

[0031] (2) A number of liquid storage tanks I provided in the present invention can store an appropriate amount of algae-removing agent that can help remove the algae attached to the caught fish. The provided round rod assembly can block a number of round holes I, so that the algae-removing agent in the number of liquid storage tanks I will not leak out. When the fish start to push up the two baffle plates I from bottom to top, causing both baffle plates I to rotate, the two baffle plates I will respectively drive the two connecting rods to move downward. When the number of blocking rods no longer completely block the number of round holes I, a part of the algae-removing agent in the number of liquid storage tanks I will flow out through the number of round holes I and flow into the cylinder through the number of liquid outlet holes I, layer by layer in the cylinder, and mix with the seawater in the cylinder. In this way, when the fish continuously swim upward through the box in the cylinder, the algae-removing agent layer by layer from bottom to top in the cylinder mixed in the seawater will also come into contact with the bodies of the fish and react with the algae attached to the fish, further helping to remove the algae attached to the fish, thereby improving the cleaning effect of the device on the algae attached to the fish.

[0032] (3) A number of liquid storage tanks II provided in the present invention can store chemical potions of amino acids and peptides that can trigger the appetite response of fish. The provided round rod assembly can also block a number of round holes II, so that the chemical potions in the number of liquid storage tanks II will not leak out. When the fish start to push up the two baffle plates I from bottom to top, causing both baffle plates I to rotate, the two baffle plates I will respectively drive the two connecting rods to move downward. When the number of blocking rods no longer completely block the number of round holes II, a part of the chemical potions in the number of liquid storage tanks II will flow out through the number of round holes II and flow into the cylinder through the number of liquid outlet holes II, layer by layer in the cylinder, and mix with the seawater in the cylinder. In this way, it can induce the appetite of the fish entering the trapping box, so that the fish in the trapping box enter the cylinder. And because the chemical bait is layer by layer from bottom to top in the cylinder, it can lure the fish to continuously swim in the cylinder and enter the through box, thereby giving the fish in the cylinder a power to enter the through box, preventing the fish entering the trapping box from staying in the trapping box or the cylinder continuously, which will hinder the process of the device trapping other fish into the cylinder to clean the algae attached to the fish, and at the same time causing the device to be unable to better catch more fish.

[0033] (4) The buoyancy board, counterweight, and scraper provided in the present invention. After the device completes the fishing task, it will be lifted out of the water. After the buoyancy board leaves the water, it will no longer be affected by the buoyancy of the water. Under the action of the gravity of the counterweight, it will press the buoyancy board to continuously slide downward, thereby driving the scraper to move downward into the cylinder and continuously move downward to the lower position inside the cylinder. During this process, the scraper will squeeze out the seaweed floating in the seawater inside the cylinder, which has been cleaned from the fish, together with the seawater, and scrape the inner wall of the cylinder from top to bottom, thereby cleaning the seaweed adhering to the inner wall of the cylinder, thus facilitating the subsequent work of the staff to clean the seaweed inside the cylinder.

[0034] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0059] Embodiment 1. Please refer to Figures 1 - 11 As shown, the present invention is a fishing device for a marine ranch, including a fishing cage 13. Symmetrically fixed to the bottom of the fishing cage 13 are support frames 14. Symmetrically hinged to the bottom of both support frames 14 are fixed anchor rods 15. Fixed to the bottom of the fishing cage 13 is a trapping box 16. Fixed to both the bottom and the inner wall of the fishing cage 13 are fish attracting lights 17. Fixed to the inner wall of the fishing cage 13 is a cylinder 18. Fixed to the top of the cylinder 18 is a through box 19. It further includes:

[0060] A fishing mechanism 1, with a fishing space provided inside the fishing mechanism 1;

[0061] A cleaning mechanism 2, provided on the inner wall of the cylinder 18;

[0062] A liquid discharging mechanism 3, provided on the outer wall of the cylinder 18;

[0063] The fishing mechanism 1 includes:

[0064] Two inlet components 11, symmetrically distributed on the inner wall of the trapping box 16;

[0065] An outlet component 12, provided on the inner wall of the through box 19;

[0066] The inlet component 11 includes a rotating shaft one 111 rotatably connected to the inner wall of the trapping box 16. Fixed to the outer wall of the rotating shaft one 111 is a baffle one 113. Symmetrically sleeved on the outer wall of the rotating shaft one 111 are torsion springs one 112. The outer walls of both torsion springs one 112 are fixedly connected to the side wall of the baffle one 113, and the outer walls of both torsion springs one 112 are fixedly connected to the inner wall of the trapping box 16. Symmetrically fixed to the inner wall of the trapping box 16 are blocking strips one 114;

[0067] The outlet component 12 includes a rotating shaft two 121 rotatably connected to the inner wall of the through box 19. Fixed to the outer wall of the rotating shaft two 121 is a baffle two 123. Symmetrically sleeved on the outer wall of the rotating shaft two 121 are torsion springs two 122. The outer walls of both torsion springs two 122 are fixedly connected to the side wall of the baffle two 123, and the outer walls of both torsion springs two 122 are fixedly connected to the inner wall of the through box 19. Fixed to the inner wall of the through box 19 is a blocking strip two 124.

[0068] In the above, the fishing cage 13 is composed of a cage body, a lid bolted to the cage body, and rings fixedly connected to the four corners of the top of the lid;

[0069] In the above, the two fish attracting lights 17 are both composed of a protective housing and a fish attracting light body fixed inside the protective housing. The protective housing prevents fish from hitting the fish attracting light body and causing damage to the fish attracting light body. The fish attracting light body is composed of a light source, a housing, waterproof and anti-corrosion designs, a battery power system, etc. It is a mature technical means in the prior art. In this solution, it is only borrowed for its function of effectively attracting fish schools underwater for a long time and providing assistance for fish fishing. The present invention will not elaborate on its structure and working principle here;

[0070] In the specific implementation of the present invention, on the shore, the lid of the fishing cage 13 is opened, a certain amount of bait such as small fish and shrimps required for fishing is placed inside the fishing cage 13, and then the lid is reinstalled and fixed on the fishing cage 13. The four rings on the fishing cage 13 are respectively connected to the steel cables for extracting the device from the water;

[0071] The device is sent to the deep water in the fish farming area of the marine ranch, and the device is fixed at the position for fishing fish in the water by using the four fixed anchor rods 15. The two fish attracting lights 17 are both powered on and in the on state;

[0072] After the device is in the water, when fish see the bait inside the fishing cage 13, they will want to enter the fishing cage 13 to eat the bait. The fish attracting light 17 at the bottom of the fishing cage 13 will attract the fish to swim to the trapping box 16. Under the dual temptation of the fish attracting light 17 and the bait inside the fishing cage 13, the fish will push against the two first baffles 113 because they want to enter the trapping box 16;

[0073] Under the continuous temptation of the fish attracting light 17, the fish will continuously push against the two first baffles 113, causing both of the two first baffles 113 to be stressed and rotate, thus creating an opening for the fish to enter the trapping box 16 through this opening;

[0074] When both of the two first baffles 113 are stressed and rotate, the two first torsion springs 112 on the same side will both deform. After the fish enter the trapping box 16, the two first baffles 113 no longer receive the pushing force from the fish. Under the reaction force of the two first torsion springs 112 on the same side, both of the two first baffles 113 return to their initial horizontal states;

[0075] After the fish enter the trapping box 16 and both of the first baffles 113 return to the horizontal state, both of the first baffles 113 will abut against the first blocking bars 114. At this time, when the fish in the trapping box 16 push against the first baffles 113, under the combined action of the first blocking bars 114, the first baffles 113 will not rotate, thus preventing the fish that enter the trapping box 16 from escaping and making it impossible for this device to complete the fishing task;

[0076] The blocking effect of the first baffles 113 on the bottom of the trapping box 16 and the function of the four first torsion springs 112 both make it require a certain amount of force to push against the first baffles 113 and make them rotate. Thus, only the big fish with a larger body size and greater strength can push against the first baffles 113 and enter the trapping box 16, while the small fish cannot enter the fishing cage 13. In this way, it can effectively reduce the situation that this device accidentally catches a large number of small fish, thereby causing damage to the ecological environment of the marine ranch;

[0077] After the fish enter the trapping box 16 and pass through the cylinder 18 and enter the through box 19, under the dual temptation of the fish attracting lamp 17 arranged on the inner wall of the fishing cage 13 and the bait in the fishing cage 13, the fish that enter the through box 19 will also push against the second baffle 123, causing the second baffle 123 to rotate and form an opening, allowing the fish in the through box 19 to enter the fishing cage 13 through this opening;

[0078] When the second baffle 123 rotates, both of the second torsion springs 122 will deform. When the fish no longer push against the second baffle 123, under the action of the two second torsion springs 122, the second baffle 123 will return to its initial state and abut against the second blocking bar 124;

[0079] At this time, when the fish that enter the fishing cage 13 push against the second baffle 123, under the action of the second blocking bar 124, the second baffle 123 will not rotate. In this way, it can prevent the fish that have entered the fishing cage 13 from returning to the through box 19, so as to stay in the trapping box 16, the cylinder 18 or the through box 19 for a long time, which will cause an adverse obstruction to the process of this device luring other fish subsequently.

[0088] The through-hole member includes a first liquid outlet hole 323 opened on the outer wall of the cylinder 18. A second liquid outlet hole 327 is opened on the outer wall of the cylinder 18. One-way valves 324 are fixedly connected to the inner walls of the first liquid outlet hole 323 and the second liquid outlet hole 327;

[0089] The brush assembly 21 includes two fixing blocks 212 symmetrically distributed and fixedly connected to the inner wall of the installation groove 211. A third rotating shaft 213 is rotatably connected to the side walls of the two fixing blocks 212. A long hairbrush 215 is fixedly connected to the outer wall of the third rotating shaft 213. Two third torsion springs 214 are symmetrically sleeved on the outer wall of the third rotating shaft 213. The outer walls of the two third torsion springs 214 are fixedly connected to the side wall of the long hairbrush 215, and the outer walls of the same-side third torsion springs 214 and the outer wall of the fixing block 212 are fixedly connected;

[0090] The scraper assembly 22 includes a long rod 223 slidably connected to the inner wall of the fishing cage 13. A buoyancy plate 222 is fixedly connected to the top of the long rod 223. A counterweight 221 is fixedly connected to the top of the buoyancy plate 222. A scraper 224 is fixedly connected to the bottom of the buoyancy plate 222;

[0091] The round rod assembly 31 includes a connecting rod 311 rotatably connected to the bottom of the round rod 312. The bottom of the connecting rod 311 is rotatably connected to the top of the first baffle 113. A number of connecting plates 314 are fixedly connected to the outer wall of the round rod 312 in an equidistant linear array. The side walls of the number of connecting plates 314 are all slidably connected to the side wall of the limiting plate 313. Two blocking rods 315 are fixedly connected to the tops of the number of connecting plates 314;

[0092] The liquid storage assembly 32 includes a first liquid storage tank 321 fixedly connected to the outer wall of the cylinder 18. A circular hole 322 is formed at the bottom of the first liquid storage tank 321. A second liquid storage tank 325 is fixedly connected to the outer wall of the cylinder 18. A circular hole 326 is formed at the bottom of the second liquid storage tank 325. The outer walls of the two plugging rods 315 are respectively slidably connected to the inner walls of the circular hole 322 and the circular hole 326.

[0093] A number of the one-way valves 324 described above are all mature technical means in the prior art. In the present invention, only the function that it only allows the flowing medium to flow in one direction and cannot flow in the other direction is borrowed here, and its structure and working principle will not be elaborated further here;

[0094] A number of the first liquid storage tanks 321 and the second liquid storage tanks 325 described above are all jointly composed of a liquid storage tank body and a round cover threadedly connected to the outer wall of the liquid storage tank body;

[0095] In the specific implementation of the present invention, after putting a number of baits such as small fish and shrimps into the fishing cage 13 on the shore, an appropriate amount of algae-removing agent that can help remove the attached algae on the caught fish is injected into a number of the first liquid storage tanks 321, and a chemical solution of amino acids and peptides that can trigger the appetite reaction of fish is injected into a number of the second liquid storage tanks 325;

[0096] After the device is fixed in deep water, under the buoyancy of water, the buoyancy plate 222 will float up overcoming the weight of the counterweight 221, thereby driving the scraping plate 224 to continuously move upward into the through box 19, and it will not affect the process of fish passing through the cylinder 18 and entering the through box 19;

[0097] When both of the two baffle plates 113 are in a horizontal state, a number of the plugging rods 315 are respectively inserted into a number of the circular holes 322 and the circular holes 326 to block a number of the circular holes 322 and the circular holes 326. At this time, the algae-removing agent and the chemical bait in a number of the first liquid storage tanks 321 and the second liquid storage tanks 325 will never flow from the upper positions inside a number of the first liquid storage tanks 321 and the second liquid storage tanks 325 to the lower positions through a number of the circular holes 322 and the circular holes 326 respectively;

[0098] When the fish trapped by this device start to push the two first baffles 113 from bottom to top, causing both of the two first baffles 113 to rotate, the two first baffles 113 will respectively drive the two connecting rods 311 to move downward, thereby driving the two round rods 312 to slide downward a certain distance respectively within the two limiting plates 313, so that a plurality of blocking rods 315 start to slide downward respectively within a plurality of first round holes 322 and second round holes 326. When a plurality of blocking rods 315 all move downward a certain distance and no longer block the upper plurality of first round holes 322 and second round holes 326 respectively, the algae-removing agents in a plurality of first liquid storage tanks 321 and the chemical baits in a plurality of second liquid storage tanks 325 will both flow from the upper positions inside the plurality of first liquid storage tanks 321 and second liquid storage tanks 325 to the lower positions inside;

[0099] The algae-removing agents flowing into the lower positions inside the plurality of first liquid storage tanks 321 will respectively further flow into a plurality of first liquid outlet holes 323, and thus flow out respectively through a plurality of one-way valves 324, all entering the cylinder 18, distributing layer by layer within the cylinder 18, and mixing with the seawater inside the cylinder 18;

[0100] The chemical baits flowing into the lower positions inside the plurality of second liquid storage tanks 325 will respectively further flow into a plurality of second liquid outlet holes 327, and thus also flow out respectively through a plurality of one-way valves 324, all entering the cylinder 18, distributing layer by layer within the cylinder 18, and mixing with the seawater inside the cylinder 18;

[0101] A plurality of one-way valves 324 function to prevent the seawater inside the cylinder 18 from entering the plurality of first liquid outlet holes 323 and second liquid outlet holes 327, filling the internal spaces of the plurality of first liquid outlet holes 323 and second liquid outlet holes 327, so that the algae-removing agents flowing into the plurality of first liquid outlet holes 323 and the chemical baits flowing into the plurality of second liquid outlet holes 327 cannot smoothly enter the cylinder 18;

[0102] After the chemical baits are distributed layer by layer within the cylinder 18 and mixed with the seawater inside the cylinder 18, they can play a role in inducing the appetite of the fish entering the trapping box 16, causing the fish in the trapping box 16 to enter the cylinder 18. And because the chemical baits are distributed layer by layer from bottom to top within the cylinder 18, they can lure the fish to continuously swim within the cylinder 18 and enter the through box 19, thereby giving the fish inside the cylinder 18 a power to enter the through box 19, preventing the fish entering the trapping box 16 from staying in the trapping box 16 or the cylinder 18 continuously, which will hinder the process of this device from trapping other fish into the cylinder 18 to clean the seaweed attached to the fish, and at the same time causing this device to be unable to better catch more fish;

[0103] When the fish in the trapping box 16 pass through the cylinder 18 and enter the through box 19, their bodies will continuously contact the bristles of several long hair brushes 215, enabling the several long hair brushes 215 to clean the seaweed attached to the fish. In this way, the seaweed attached to the fish can be cleaned, reducing the amount of seaweed attached to the caught fish, preventing the need to clean a large amount of seaweed attached to the fish after they are caught ashore, thus delaying the time for subsequent processing of the caught fish, and at the same time preventing the fish caught in the fishing cage 13 from being attached with a large amount of seaweed for too long, as the decomposition of seaweed and other organic matters may affect the quality of the fish meat;

[0104] When the fish continuously swim from the cylinder 18 into the through box 19, the algicide mixed in the seawater and distributed layer by layer from bottom to top in the cylinder 18 will also contact the bodies of the fish and react with the seaweed attached to the fish, further helping to remove the seaweed attached to the fish, thereby improving the cleaning effect of the device on the seaweed attached to the fish;

[0105] When the fish enter the trapping box 16 and no longer push against the two first baffles 113, under the reaction force of the two first torsion springs 112 on the same side, the two first baffles 113 will rotate and return to their initial horizontal positions. During this process, the two first baffles 113 respectively drive the two connecting rods 311 to move upward, thereby driving the two round rods 312 to slide upward in the two connecting plates 314 respectively, thus driving several connecting plates 314 to all start sliding upward, and then driving several blocking rods 315 to all start sliding upward, so that several blocking rods 315 all return to the state of initially blocking several first round holes 322 and second round holes 326 respectively. In this way, the liquid medicines located above the internal upper positions of several first liquid storage tanks 321 and second liquid storage tanks 325 will no longer flow out through several first round holes 322 and second round holes 326;

[0106] After the device completes the fish-catching task, it will be lifted out of the water. After the buoyancy plate 222 leaves the water, it will no longer be affected by the buoyancy of the water. Under the gravity of the counterweight 221, it will press the buoyancy plate 222 to continuously slide downward, thereby driving the scraper 224 to move downward into the cylinder 18 and continue to move downward to the lower position inside the cylinder 18. During this process, the scraper 224 will squeeze out the seaweed floating in the seawater inside the cylinder 18 and cleaned from the fish bodies together with the seawater out of the cylinder 18, and scrape the inner wall of the cylinder 18 from top to bottom, thereby cleaning the seaweed adhering to the inner wall of the cylinder 18, thus facilitating the subsequent work of the staff to clean the seaweed inside the cylinder 18;

[0107] When the scraping plate 224 continuously moves downward in the cylinder 18, it will press on several long hair brushes 215, causing several long hair brushes 215 to rotate and be received into several installation grooves 211. At this time, several torsion springs three 214 will deform. When several long hair brushes 215 are not stressed, due to the reaction force of several torsion springs three 214, several long hair brushes 215 will rotate and return to their initial states.

[0108] A specific application of this embodiment is as follows:

[0109] Open the lid of the fishing cage 13 on the shore, put a certain amount of bait such as small fish and shrimps required for fishing in the fishing cage 13, inject an appropriate amount of algae-removing agent that can help remove the attached seaweed on the caught fish into several first liquid storage tanks 321, inject chemical potions of amino acids and peptides that can trigger the appetite reaction of fish into several second liquid storage tanks 325, reinstall the lid on the fishing cage 13, and connect the four rings on the fishing cage 13 to the steel cables for extracting the device from the water respectively;

[0110] Send the device to the deep water in the fish farming area of the marine ranch, fix the device at the position for catching the required fish in the water by using four fixed anchor rods 15, and turn on the power of both fishing lights 17 to make them both in the on state;

[0111] The fishing light 17 at the bottom of the fishing cage 13 will lure fish to swim to the trapping box 16. Under the double temptation of the fishing light 17 and the bait in the fishing cage 13, the fish will want to enter the fishing cage 13 to eat the bait, thus pushing two first baffles 113, causing both first baffles 113 to be stressed and rotate, resulting in an opening for the fish to enter the trapping box 16 through this opening;

[0112] During this process, when both first baffles 113 rotate, they will respectively drive two connecting rods 311 to move downward, thereby driving two round rods 312 to slide downward by a certain distance in two limit plates 313 respectively, so that several blocking rods 315 start to slide downward in several first round holes 322 and second round holes 326 respectively. Since several blocking rods 315 all move downward by a certain distance and no longer block the upper several first round holes 322 and second round holes 326 respectively, a part of the algae-removing agent in several first liquid storage tanks 321 and the chemical bait in several second liquid storage tanks 325 will flow out through several first round holes 322 and second round holes 326 respectively, and further flow into several first liquid outlet holes 323 and second liquid outlet holes 327 respectively, and flow out through several first liquid outlet holes 323 and second liquid outlet holes 327 and enter the cylinder 18;

[0113] When the fish enter the trapping box 16 and no longer push against the two first baffles 113, under the reaction force of the two torsion springs 112 on the same side, the two first baffles 113 will rotate to restore their initial horizontal positions. During this process, the two first baffles 113 drive the two connecting rods 311 to move upward respectively, thereby driving the two round rods 312 to slide upward in the two connecting plates 314 respectively, thereby driving a plurality of connecting plates 314 to start sliding upward, thereby driving a plurality of blocking rods 315 to start sliding upward, so that a plurality of blocking rods 315 all return to the state of initially blocking a plurality of first round holes 322 and second round holes 326 respectively;

[0114] After the chemical bait is distributed layer by layer in the cylinder 18 and mixed with the seawater in the cylinder 18, it can play a role in inducing the appetite of the fish entering the trapping box 16, so that the fish in the trapping box 16 enter the cylinder 18, and lure the fish to continuously swim in the cylinder 18 and enter the through box 19;

[0115] During this process, the body of the fish will continuously contact the bristles of a plurality of long hair brushes 215, so that the a plurality of long hair brushes 215 can clean the seaweed attached to the fish. The algicide mixed in the seawater in the cylinder 18 will also contact the body of the fish and react with the seaweed attached to the fish, further helping to remove the seaweed attached to the fish;

[0116] After the fish enter the through box 19, under the double temptation of the fish attracting lamp 17 arranged on the inner wall of the fishing cage 13 and the bait in the fishing cage 13, the fish entering the through box 19 will also push against the second baffle 123, causing the second baffle 123 to rotate to form an opening, so that the fish in the through box 19 can enter the fishing cage 13 through this opening, thus completing the fishing of the fish;

[0117] After the device completes the fishing task of the fish, it will be lifted out of the water. After the buoyancy plate 222 leaves the water, it will no longer be affected by the buoyancy of the water. Under the gravity of the counterweight 221, it will press the buoyancy plate 222 to continuously move downward to the lower position inside the cylinder 18. During this process, the scraper 224 will squeeze out the seaweed floating in the seawater in the cylinder 18 that has been cleaned from the fish together with the seawater out of the cylinder 18, and scrape the inner wall of the cylinder 18 from top to bottom, thereby cleaning the seaweed adhering to the inner wall of the cylinder 18.
