Description

Technical Field

[0001] This invention relates to the field of fishing equipment technology, specifically to a fishing boat with a suction function. Background Technology

[0002] Trawling is one of the most important and productive marine fishing methods in the world. It uses the power of a fishing boat to tow a large fishing net, which travels through the middle or bottom layers of the seawater to catch fish, shrimp and other organisms in the area.

[0003] In the prior art, for example, the invention patent with publication number CN115843753B discloses a trawl device and fishing vessel, the invention patent with publication number CN116076455B discloses a fishing vessel trawl with a net bag that can be quickly separated, and the invention patent application with publication number CN113693037A discloses a fishing vessel trawl device with anti-crushing net inside the net applied to marine fishery engineering. The trawl structure in the above devices uses the towing and interception method to catch fish. After the trawl has passed, it is impossible to carry out secondary fishing operations on the fish that have escaped the catch in time, resulting in low fishing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a fishing boat with a suction function to solve the problems mentioned in the background art above:

[0005] After trawling, it is impossible to catch any fish that have escaped the initial catch in time, resulting in low fishing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The slide bar is horizontally arranged, and its two ends are fixedly connected to the sides of the two lifting rings that are close to each other. The slider is horizontally slidably sleeved on the lead screw and the slide bar. The slider is threadedly sleeved with the lead screw. The fish suction pump is fixedly installed on the outside of the slider.

[0012] Furthermore, the front bumper assembly includes a first sealing ring, multiple sealing plates, multiple rotating shafts, and a linkage component. The first sealing ring is rotatably connected to the front end of the cage. The multiple rotating shafts are all vertically rotatably installed inside the first sealing ring. The multiple sealing plates are respectively vertically fixedly sleeved on the multiple rotating shafts. The linkage component is located inside the first sealing ring and is used to drive the multiple rotating shafts to deflect simultaneously. The guide tube is fixedly connected to the outside of the first sealing ring through a locking block (33).

[0013] Furthermore, the rear baffle assembly includes a second sealing ring, a connector, an impeller, a mesh plate, and a locking device. The second sealing ring is hinged to the rear end side of the cage via the connector. The locking device is fixedly installed at the connection between the cage and the second sealing ring and is opposite to the connector.

The top ends of the two steel cables are wound and connected to the winding device.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] (1) With the cooperation of the fish suction mechanism, fish that have missed the front entrance of the cage can be transported in time and moved to the front of the cage again for secondary fishing in a short time, thereby improving fishing efficiency.

[0018] (2) During the mobile fishing process, the water flows backward and impacts the impeller to rotate. The impeller causes the cage to rotate and the multiple guide plates inside it to rotate. The guide plates press water into the cage, which can impact the fish inside the cage, reduce the contact between the fish inside the cage and the inner wall of the cage, and reduce damage.

[0019] (3) During the rotation of the cage, the net tube is rotated, which is conducive to the evaporation of the bait inside the net tube. Combined with the fish-attracting lamp device, it can attract fish more effectively, causing fish that have missed the front entrance of the cage to gather on the outside of the cage, making it easier for the fish pump to carry them out fully, and further facilitating secondary fishing in a short time.

The two steel cables 29 are respectively embedded in the two pulleys 32, and their bottom ends are fixedly connected to the top of the two lifting rings 3. The top ends of the two steel cables 29 are wound and connected to the winding device 28.

[0041] The working principle of the fishing boat involved in this application:

[0042] When the vessel 1 sails to the fishing area and begins fishing, the steel cables 29 on both sides are released under the operation of the winding device 28, causing the fishing mechanism to move down to the preset depth of the water.

[0043] When fishing is carried out in waters of a preset depth, multiple sealing plates 14 are in a horizontal state, thereby making the first sealing ring 13 open and catching fish. As the boat 1 moves, the fish in front of the cage 2 enter the cage 2 through the gaps between the multiple sealing plates 14, thus catching them. At the same time, multiple fish-attracting lamps 4 light up to attract the fish. The cage 2 moves with the boat 1, causing the turbine 10 to rotate due to the impact of the water flow. The turbine 10 drives the lead screw 8 to rotate. Driven by the reciprocating screw, the slider 12 moves back and forth, driving the fish suction pump 5 to move back and forth. The suction end of the fish suction pump 5 moves along the fish-attracting lamp 4 to suck up the fish attracted by the fish-attracting lamp 4, and then discharges them into the guide pipe 6 through the delivery pipe 7. Finally, the fish are transported to the front port of the first sealing ring 13 through the guide pipe 6 and enter the cage 2.

[0044] With the assistance of the fish suction mechanism, fish that have missed the inlet at the front of the cage 2 can be transported in time and moved back to the front of the cage 2 for secondary fishing in a short time, thus improving fishing efficiency.

[0045] During mobile fishing, the water pushes the fish at the front of the cage 2 into the cage, while the water flows backward and impacts the impeller 22 to rotate. The impeller 22 drives the cage 2 to rotate through the second sealing ring 20. The cage 2 drives the multiple guide plates 25 located inside it to rotate. The guide plates 25 press water into the cage 2, which can impact the fish inside the cage 2, reduce the contact between the fish inside the cage 2 and the inner wall of the cage 2, and reduce damage.

[0046] As the cage 2 rotates, it drives the net tube 27 to rotate, which helps the bait inside the net tube 27 to evaporate. Combined with the fish-attracting light device 4, it attracts fish more effectively, causing fish that missed the front entrance of the cage 2 to gather on the outside of the cage 2, making it easier for the fish pump 5 to fully guide them, and further facilitating secondary fishing in a short time.

[0047] After the fishing operation is completed, the motor 16 starts, driving the transmission shaft 19 to rotate. The transmission shaft 19 drives multiple first gears 17 to rotate. The first gears 17 drive the corresponding rotating shafts 15 to rotate through multiple second gears 18, thereby causing multiple sealing plates 14 to deflect synchronously, blocking the input end inside the first sealing ring 13, and preventing fish and shrimp that have been caught in the net from flowing out when the net is pulled up.

[0048] After the fishing operation is completed, the net hauling operation is carried out. The winding device 28 is started to wind up the steel cable 29. After the cage 2 rises to the side of the hull 1, the two lifting rings 3 respectively engage the sides of the two trusses 31. The power unit 35 is started, driving the main shaft 34 to rotate. The main shaft 34 drives the two trusses 31 to deflect, so that the trusses 31 drive the cage 2 to flip to the upper side of the hull 1. The cages 2 on both sides work synchronously. Then the locking device 24 is opened to open the second sealing ring 20, so that the rear end of the cage 2 is open, and the caught fish and shrimp are unloaded, completing the fishing operation.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
