Description

[Technical field]

[0001] The invention relates to the technical field of fishing, in particular to a net trap fishing device. [Background technology]

[0002] In daily life, people usually fish on the shore or take a boat to the corresponding water surface in rivers, lakes, seas and reservoirs, using fishing rods and other fishing tools to fish. The rod-line fishing method is inefficient and belongs to the traditional blind fishing method. Whether fishing on the shore or taking a boat to the corresponding water surface, the number of anglers is generally limited. It is precisely this fishing method that makes the fun of fishing only experienced by the anglers themselves and difficult to share.

[0003] In addition, for many anglers, the method of fishing in the corresponding waters by boat has the disadvantage of high cost. If you take a general simple buoyancy platform, there will be safety hazards and inconvenience in carrying.

[0004] To this end, the present invention aims at the above-mentioned traditional inefficient blind fishing method and innovatively studies and invents a net trap fishing device. [Summary of the invention]

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. The present invention provides a new fishing method for fishing enthusiasts by configuring a fish-attracting component for inducing fish to enter the enclosed space and / or a visiting component for observing the gathering of fish inside and around the enclosed space on the net trap component or the side of the floating platform on the water, and innovatively uses a net trap component with a controllable opening in combination with a visual visiting component and / or a fish-attracting component. The fisherman can observe the fish entering the enclosed space through the visiting component to decide when to close the entrance of the enclosed space, and the fisherman can further induce the fish to enter the enclosed space through the fish-attracting component, thereby improving the efficiency of fishing; and when fish enter the enclosed space and the entrance is closed, the fisherman can control the opening on the net trap component to rise to be basically flush with the surface of the floating platform on the water, so that the fisherman can scoop up the fish in the enclosed space, which has the characteristics of convenient operation, high efficiency and more entertainment.

[0029] 2. The corresponding upper cover mesh is kept close to the surface of the floating platform on the water by the mesh locking piece, which can ensure that the net trap assembly is more stable relative to the floating platform on the water, avoid interference during the fish scooping process, and avoid the net trap assembly shaking relative to the floating platform on the water to affect the fish scooping; in addition, the upper cover mesh locked to the floating platform on the water can also be stepped on by anglers during the fish scooping process, further facilitating the anglers to approach the net trap assembly for scooping fish, thereby realizing the characteristics of diversified functional use.

[0030] 3. When the net trap assembly of the present invention adopts a rigid net trap cage, telescopic rods are connected between two adjacent net trap annular rings at intervals, and the net trap cage can be telescoped according to usage requirements, which is beneficial to reducing the space required for storage and is convenient for storage and carrying.

[0031] 4. When the net trap component of the present invention uses a flexible sleeve net, the lower end of the soft sleeve net is pulled by the cooperation of the fish driving winch component and the pulling and swinging flexible member. That is, during the process of the angler scooping the fish, the fish driving winch component winds up the pulling and swinging flexible member to pull up the lower end of the sleeve net, and the fish in the fish trapping space of the sleeve net can be driven upward to the opening for the angler to scoop the fish; in addition, the fish driving winch component can also wind up the pulling and swinging flexible member to pull up the lower end of the sleeve net so that the lower end of the sleeve net is aligned with the mouth of the fish basket, and then the fish can be released by opening the lower opening of the sleeve net; moreover, the fish driving winch component is arranged deviating from the directly above position of the net trap component, and the pulling and swinging flexible member is obliquely connected to the lower end of the sleeve net, so it will not interfere with scooping the fish when winding up and driving the fish.

[0032] 5. In order to avoid the fish attracting component from affecting scooping the fish, the hanging part arranged on the side of the fish attracting component is hung on the side of the net trap component to achieve the positioning purpose.

[0033] 6. In the present invention, a spreading ring is connected to the lower opening of the sleeve net. Through the spreading ring, it can be ensured that the lower opening of the sleeve net is always in the maximum open state, which is convenient for the lower cover of the net trap to smoothly enter and exit the lower opening of the sleeve net to achieve a better effect of the fish entering the trapping space; at the same time, the spreading ring can also play a certain role in weighing the sleeve net so that the sleeve net remains vertical in the water.

Specific Embodiments

[0051] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings.

[0052] As Figures 1-16As shown in the figure, a net trap fishing device of the present invention includes a bracket assembly 2 that can be stably installed on a water buoyancy platform 1. A net trap assembly 4 is suspended on the bracket assembly 2 so as to be liftable relative to the water buoyancy platform 1. A net trap winch assembly 3 for controlling the up and down movement of the net trap assembly 4 relative to the water buoyancy platform 1 is also provided on the bracket assembly 2. The net trap assembly 4 is configured to have a trapped space 400 that can selectively open or close the entrance at least when sinking into the water. The net trap fishing device further includes a fish attracting assembly 5 and / or a viewing assembly 6. The fish attracting assembly 5 and / or the viewing assembly 6 is relatively fixed or relatively movable and is arranged on the net trap assembly 4 or on the side of the water buoyancy platform 1. The fish attracting assembly 5 is configured to induce fish to enter the trapped space 400 after the net trap assembly 4 sinks into the water. The viewing assembly 6 is configured to observe the gathering situation of fish inside and around the trapped space 400 after the net trap assembly 4 sinks into the water. The net trap winch assembly 3 is configured to limit the up or down movement of the net trap assembly 4 relative to the water buoyancy platform 1 to the maximum stroke and lock at any position within the maximum stroke range of up or down movement. In the present invention, the fish attracting assembly 5 and the viewing assembly 6 can be selectively configured and installed on the net trap assembly 4 or on the side of the water buoyancy platform 1. During operation, after the angler controls the net trap assembly to descend relative to the water buoyancy platform 1 and sink into the water through the net trap winch assembly, the entrance of the trapped space on the net trap assembly is opened. According to the corresponding configuration, the angler can manually scatter bait into the trapped space on the net trap assembly or induce fish to enter the trapped space of the net trap assembly through the fish attracting assembly. The angler can observe the gathering situation of fish inside and around the trapped space through the viewing assembly, so as to achieve the purpose of visualizing in real time and facilitating the angler to share the fishing scene, effectively improving the efficiency and entertainment of fishing. In addition, by controlling the net trap assembly to descend to different depths, the angler can choose to catch fish living in waters at different depths. Moreover, by using the net trap for fishing in this application, the caught fish will not be damaged, ensuring that the caught fish remains fresh and lively.

[0053] The present invention abandons the traditional inefficient blind fishing method using a fishing rod, and innovatively uses a net trap assembly with a controllable opening combined with a visual viewing assembly and / or a fish attracting assembly. The angler can observe the fish entering the trapped space through the viewing assembly to decide when to close the entrance of the trapped space, and the angler can further induce fish to enter the trapped space through the fish attracting assembly, improving the fishing efficiency. And when there are fish in the trapped space and the entrance is closed, the angler can control the opening on the net trap assembly to rise to be basically flush with the surface of the water buoyancy platform, so that the angler can scoop up the fish in the trapped space, which has the characteristics of convenient, efficient and more entertaining operation.

[0054] The present invention can be implemented in waters such as rivers, lakes, seas and reservoirs, with the aid of a bracket assembly that can be stably erected on various water surface buoyancy platforms and can hang the net trap assembly as a necessary condition. The various water surface buoyancy platforms include but are not limited to air bag buoyancy platforms that can be quickly disassembled and transported, buoyancy box platforms that can be quickly assembled and disassembled, integral annular water surface buoyancy platforms with strong wind and wave resistance, and other floating islands.

[0055] In order to better protect the fishery, when in use, the mesh aperture of the net trap assembly of the present invention is larger than the mesh aperture required by relevant laws and regulations.

[0056] like Figures 1-5 As shown, as a first embodiment of the net trap assembly 4, the net trap assembly 4 includes a hard net trap cage body 41 with upper and lower openings, the upper portion of the net trap cage body 41 is directly or indirectly connected to the net trap winch assembly 3, the upper opening of the net trap cage body 41 is movably covered with a net trap upper cover 411, the lower portion of the net trap cage body 41 is provided with a net trap lower cover 412 which can control the opening and closing of the lower opening of the net trap cage body 41, and the fish attracting assembly 5 is arranged on the upper portion of the net trap cage body 41 and rises and falls in coordination with the net trap cage body 41. During the process of net trap fishing, the net trap lower cover 412 opens the lower opening of the net trap cage body 41, and the fish attracting component 5 works to induce the fish to enter the enclosed space of the net trap cage body 41 from the lower opening of the net trap cage body 41. When the visiting component 6 observes that the fish catch inside the enclosed space 400 reaches the expected level, the net trap lower cover 412 closes the lower opening of the net trap cage body 41, and the net trap winch component 3 controls the net trap component 4 to rise to a preset height relative to the water buoyancy platform 1, and opens the upper cover mesh 413 to facilitate the angler to scoop fish from the upper opening of the net trap cage body 41; in this embodiment, the net trap cage body 41 is made of stainless steel or other hard materials, and has the characteristics of stable structure, strong durability and high ecological compatibility.

[0057] like Figures 1-5 As shown, for the convenience of operation, the net trap upper cover 411 is composed of a plurality of upper cover meshes 413, and the outer side of each upper cover mesh 413 is hinged to the side of the upper opening of the net trap cage body 41, and a net trap avoidance hole 414 is formed between the plurality of upper cover meshes 413 covering the upper opening of the net trap cage body 41 for the fish attracting component 5 to extend into the enclosed space 400. In this embodiment, the fish attracting component 5 extends into the enclosed space 400 through the net trap avoidance hole 414, that is, the inner wall of the net trap avoidance hole can limit and position the fish attracting component to a certain extent, effectively reduce the angle of the fish attracting component 5 relative to the net trap component shaking and offsetting, and ensure the stable operation of the fish attracting component 5.

[0058] like Figure 1 , 2As shown in Figures 5 and 6, one side of the net trap lower cover 412 is hinged to one side of the lower opening of the net trap cage 41, and the other side of the net trap lower cover 412 is connected to an opening and closing control flexible member 415, and a guide member for guiding the opening and closing control flexible member 415 is provided at a corresponding position of the lower opening of the net trap cage 41, and the other end of the opening and closing control flexible member 415 is connected to an opening and closing hoisting component 416 provided on the bracket assembly 2. When in use, the opening and closing hoisting component 416 pulls the net trap lower cover 412 through the opening and closing control flexible member 415, so that the net trap lower cover 412 rotates accordingly to open or close the lower opening of the net trap cage 41. The opening and closing control flexible member 415 in the present invention can adopt a flat belt structure to ensure that the opening and closing control flexible member 415 is smooth and stable during the hoisting process, thereby ensuring that the net trap lower cover 412 moves smoothly and steadily during the pulling process.

In this embodiment, only one set of net trap hoist assembly 3 is connected to the connecting frame 417 to simultaneously control the coordinated action of the net trap cage 41 and the fish attracting assembly 5, which effectively reduces the manufacturing cost and has a simple structure. In addition, the net trap cage 41 is suspended below the connecting frame 417 with upper and lower separation, which reduces the interference of the connecting frame 417 with the net trap upper cover 411, making it convenient for the net trap upper cover 411 to be rotated and opened and for the fisherman to scoop fish.

[0060] like Figure 1 , 3 As shown, the bracket assembly 2 includes a support column 21 for connecting to the floating platform 1 on the water, and the upper cover mesh 413 located on the side of the support column 21 is provided with a mesh notch 418 for avoiding the support column 21 and being close to the surface of the floating platform 1 on the water when the upper cover mesh 413 is turned over. The support column 21 is provided with a mesh locking piece 211 to keep the corresponding upper cover mesh 413 close to the surface of the floating platform 1 on the water, which can ensure that the net trap assembly is relatively stable when it is lifted to be flush with the upper surface of the floating platform on the water, and reduce the shaking of the net trap assembly relative to the floating platform on the water during the fish scooping process by the angler, which affects the efficiency of fish scooping and causes hidden dangers; in addition, the upper cover mesh locked to the floating platform on the water can also support the angler to step on it, so that the angler can approach the net trap assembly to scoop fish, which is convenient to use and has complete and diverse functions.

[0061] like Figure 1 , 2, as shown in Figures 6, 7, and 9, the support assembly 2 includes a plurality of support columns 21 for connecting with the floating platform 1 on water.

[0064] As Figure 9 shown, the net trap hoisting assembly 3 and the cover hoisting component are correspondingly arranged on the outer end of the hanging cantilever 22. Among them, the inner ends of several hanging cantilevers 22 are connected and fixed to each other through cantilever plug-in seats, so as to form an integral structure and improve the structural strength. The cantilever plug-in seat can be a standardized plastic-coated hardware reinforcement base or other structures.

[0065] As Figure 3 shown, the net locking member 211 is slidably connected to the support column 21, and the net locking member 211 is connected with a locking screw for locking the net locking member 211 relative to the support column 21.
