Description

Technical Field

[0001] This utility model relates to the field of fishing equipment technology, and in particular to a marine fishing equipment. Background Technology

[0002] In recent years, the marine aquaculture industry has developed rapidly, and more and more fishermen are improving their quality of life through marine aquaculture. The scale of aquaculture is also getting larger and larger. When the farmed organisms mature, fishermen often catch various fish by casting nets, driving fish, and hauling in the nets.

[0003] A Chinese utility model patent with a publication date of November 26, 2021, discloses a shrimp catching device, including columns, a top cover, a bottom plate, a plastic net, a guide net, a counterweight ring, base feet, a shielding curtain, a counterweight rod, and a pull rope. The top cover and bottom plate are arranged opposite each other in the vertical direction and spaced apart. The columns are arranged vertically, with the upper end of the column connected to the top cover and the lower end connected to the bottom plate. The columns can extend and retract in the vertical direction. There are multiple columns, which are arranged at intervals along the circumference of the bottom plate. A plastic net connects any two adjacent columns. The top cover, bottom plate, columns, and plastic net define a catching box. An inlet is provided at the center of the plastic net. The guide net is located inside the catching box and is located at the inlet. The guide net is a ring-shaped cone-shaped net, and it gradually contracts in the direction from the inlet to the inside of the catching box.

[0004] In operation, the aforementioned technology involves placing the fishing device stably on the bottom of the water. After a certain period, shrimp can enter the fishing box through the open inlet and guide net to feed on the bait. The pull rope is then released, and under the weight of the counterweight, the barrier curtain automatically closes the inlet again, allowing the device to be removed and the shrimp to be caught. However, when the device is removed, the fish inside need to be cleaned, a process that is usually time-consuming, resulting in extended downtime and reduced fishing efficiency. Utility Model Content

[0005] The main objective of this invention is to provide a marine fishing device that reduces downtime and improves fishing efficiency.

[0006] To achieve the above objectives, this utility model proposes a marine fishing device, including a top cover. First pillars are fixedly connected to the four corners of the bottom of the top cover. First plastic nets are fixedly connected between each of the first pillars, and first guide nets are fixedly connected to the sides of each of the first plastic nets. Second plastic nets are fixedly connected to the bottom of each pillar, and second guide nets are fixedly connected to the bottom of the second plastic nets. The cross-sectional area of ​​the second guide nets gradually decreases from top to bottom.

[0007] It also includes a trap box, with a second column fixedly connected to each of the four corners of the trap box. Each side of the trap box has a through hole, and the side with the smaller cross-sectional area of ​​the second guide net is connected to the inside of the trap box.

[0008] It also includes a fixing component, which is used to fix each second column to its corresponding first column.

[0009] In one possible implementation, the fixing assembly includes a fixing plate rotatably connected to the side of each of the first columns, a fixing bolt threadedly connected to the fixing plate, and threaded holes respectively opened on the side of each of the second columns. The side of the fixing plate abuts against the side of the first column and the side of the second column, the bolt head side of the fixing bolt abuts against the side of the fixing plate, and one side of the fixing bolt is threadedly connected to the inside of the threaded hole.

[0010] In one possible implementation, a positioning block is fixedly connected to the top of each of the second columns, and a positioning groove is provided at the bottom of each of the first columns, with each positioning block slidingly connected to the corresponding positioning groove.

[0011] In one possible implementation, the cross-sectional area of ​​each positioning block gradually increases from top to bottom, and each positioning block is interference-fitted with the inner wall of the corresponding positioning groove.

[0012] In one possible implementation, each of the first and second guide nets is equipped with an anti-escape component. The anti-escape component includes an anti-detachment block disposed inside the first and second guide nets respectively, a support frame fixedly connected to the first and second guide nets respectively, and an elastic member disposed between the anti-detachment block and the support frame. One side of each elastic member is fixedly connected to one side of the support frame, and the other side of each elastic member is fixedly connected to the anti-detachment block. There is a gap between the side of the anti-detachment block and the inner wall of the first and second guide nets.

[0013] In one possible implementation, the anti-detachment block has an overall conical structure, with the side of the anti-detachment block with a smaller cross-sectional area located inside the first guide net and the second guide net.

[0014] In one possible implementation, a limiting rod is fixedly connected to the side of the anti-detachment block, the limiting rod is slidably connected to the support frame, and an elastic element is sleeved on the outer surface of the limiting rod.

[0015] Working principle and beneficial effects:

[0016] This invention divides the device into upper and lower parts. The upper part is responsible for inducing and initial capture, while the lower part (the trap box) is specifically designed for collecting the catch. When cleaning is required, the trap box can be quickly separated from the upper main body using a fixing component. Cleaning can be completed by simply tilting or washing the relatively small and structurally independent trap box, eliminating the need to handle the entire large device. This reduces non-fishing operation time, allowing the fishing device to be put back into the water more quickly and improving the fishing efficiency per unit time.

[0017] In addition, operators can set up an extra trap box. When the fishing device is brought to the surface, workers can use securing components to separate the trap box from the main body, then replace it with a brand new trap box and secure it using the same components. Afterward, the new trap box can be returned to the sea to continue fishing operations. This method reduces the downtime for cleaning the fishing device, thereby further improving fishing efficiency.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] Example 1:

[0029] refer to Figure 1-5 This embodiment proposes a marine fishing device, including an upper fishing guidance module and a lower centralized collection module. The fishing guidance module is a three-dimensional frame structure composed of a top cover 1, first pillars 101, first plastic nets 102, and first guide nets 1021. The top cover 1 is rectangular, with a first pillar 101 vertically fixed to each of its four bottom corners. These first pillars 101 extend vertically and together form the supporting skeleton of the module. Between adjacent first pillars 101, a soft and water-permeable first plastic net 102 is tensioned and fixedly connected, forming a fishing chamber with an opening at the top closed by the top cover 1 and open sides. Simultaneously, a second plastic net 103 is fixedly connected to the bottom of each pillar.

[0030] An entrance is provided in the central region of each first plastic net 102, and a funnel-shaped first guide net 1021 is fixedly connected to the inside of the entrance. The larger end of the first guide net 1021 is sealed to the entrance edge on the first plastic net 102, and its net body extends into the fishing chamber and gradually narrows to form a guide channel.

[0031] Secondly, an entrance is provided in the central area of ​​the second plastic net 103, and a funnel-shaped second guide net 104 is fixedly connected to the inside of the entrance, and the cross-sectional area of ​​the second guide net 104 gradually decreases from top to bottom.

[0032] Directly below the trapping and guiding module, there is an independent and detachable centralized collection module, namely the trapping box 105. The trapping box 105 is also generally rectangular, with its four corners reinforced and supported by second pillars 106. The sides of the trapping box 105 are not completely sealed, but have dense perforations to allow water exchange while preventing captured organisms from escaping. The top of the trapping box 105 is open, and the side with the smaller cross-sectional area of ​​the second guide net 104 communicates with the interior of the trapping box 105, allowing shrimp or fish to enter.

[0033] To securely connect the two modules into a single unit for operation, a dedicated fixing assembly is provided between the fishing guidance module and the trapping box 105. Specifically, an L-shaped fixing plate 2, which can rotate horizontally, is hinged to the bottom side of each first column 101 via a pivot. Internally threaded holes 202 are pre-machined on the top side of the corresponding second column 106. When assembly is required, the trapping box 105 is raised so that the top of its second column 106 approaches and aligns with the bottom of the corresponding first column 101. Then, the fixing plate 2 is rotated so that it simultaneously fits against the sides of both the first and second columns 101. Next, the fixing bolts 201 are screwed into the through holes on the fixing plate 2 until the ends of the fixing bolts 201 are tightly screwed into the threaded holes 202 of the second column 106. Through the tightening force of the bolts, the fixing plate 2 is pressed tightly against the two columns, thus achieving the fixation between the two first columns 101 and the second column 106. This structure ensures that the device will not accidentally detach when subjected to water flow or biological impact underwater. When the trap box 105 needs to be separated for cleaning, the locking can be released simply by loosening the bolts. The entire process requires no complicated tools or a lot of time, further improving work efficiency.

[0034] To enable rapid pre-positioning before installing the fixing components, an upwardly protruding positioning block 203 is integrally formed on the top of the second column 106, while a positioning groove 204 with a matching shape is machined on the bottom of the first column 101. The positioning block 203 is designed with a cross-sectional area that gradually increases from top to bottom and has a trapezoidal cross-section, and the positioning groove 204 is also shaped to match it.

[0035] When installing the trap box 105, the operator only needs to roughly align each positioning block 203 with the upper positioning groove 204, and then push the trap box 105 upwards. The positioning blocks 203 will then slide into the positioning groove 204. Due to the trapezoidal structure design and interference fit, the positioning blocks 203 will be naturally guided to center during the process of entering the positioning groove 204, and will generate a certain frictional fastening force after being fully inserted. This allows the two modules to maintain temporary stability before being formally fixed, greatly facilitating the subsequent rotation of the fixing plate 2 and the tightening of the bolts.

[0036] Example 2:

[0037] Based on Example 1, and referring to Figure 6 In order to improve the capture rate and prevent marine organisms from escaping into the device, this embodiment provides an escape prevention component at the entry points of each first guide net 1021 and second guide net 104. The escape prevention component includes an anti-detachment block 3 disposed inside the first guide net 1021 and the second guide net 104, a support frame 301 fixedly connected to the first guide net 1021 and the second guide net 104, and an elastic member 302 disposed between the anti-detachment block 3 and the support frame 301. One side of each elastic member 302 is fixedly connected to one side of the support frame 301, and the other side of each elastic member 302 is fixedly connected to the anti-detachment block 3. There is a gap between the side of the anti-detachment block 3 and the inner wall of the first guide net 1021 and the second guide net 104.

[0038] Meanwhile, the anti-detachment block 3 has a cone-shaped structure, with its cone tip facing the entrance of the first guide net 1021 and the second guide net 104. That is, the side of the anti-detachment block 3 with a smaller cross-sectional area is located inside the first guide net 1021 and the second guide net 104.

[0039] In its natural state, the spring force pushes the anti-detachment block 3 towards the entrance of the guide net, causing its conical surface to partially block the passage. An annular gap remains between the side of the anti-detachment block 3 and the inner wall of the guide net. When fish, shrimp, or other organisms attempt to enter from the outside, they can push against the conical surface of the anti-detachment block 3, overcoming the spring force and causing it to move backward, thus widening the passage for entry. Once the organism has passed, the spring immediately pushes the anti-detachment block 3 back to its original position, reforming the barrier. Due to the conical structure of the anti-detachment block 3, organisms attempting to escape from the inside have difficulty finding a point of leverage to push it open, thus being trapped inside and ensuring efficient harvesting.

[0040] To ensure smooth and non-deflecting movement of the anti-detachment block 3, a limiting rod 303 is fixed at the center of its back. This limiting rod 303 passes forward through a pre-set guide hole in the center of the support frame 301 and engages with it. The aforementioned compression spring is sleeved on the outside of this limiting rod 303. This design ensures that the anti-detachment block 3 can only reciprocate linearly along the axial direction of the limiting rod 303, ensuring stable movement. Simultaneously, it ensures uniform force distribution on the elastic element 302, thereby extending its service life.

[0041] To further expand and enhance the trapping effect of this embodiment, an optical trap can also be installed at the center of the inner top wall of the trapping box 105. This optical trap includes a waterproof shell, a battery, and an LED light source of a specific wavelength. Its light source can be designed to emit blue-green light, which travels a long distance underwater and has a significant attraction effect on many marine organisms. The optical trap is detachably installed inside the trapping box 105, and its power switch can be set to be triggered by external magnetic control or water pressure, automatically lighting up when the device is submerged to a certain depth in the water to enhance the attraction effect on target organisms. It works in conjunction with the physical bait placed inside the trapping box 105 to further improve capture efficiency. This is prior art well known to those skilled in the art, and will not be described further in this embodiment.
