[0070] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0071] refer to Figure 1 In some embodiments, the net-catching device includes a mounting base 1, a support arm 2, a swing arm 3, a fishing net assembly 4, and a first power component 5.

[0072] Support arm 2 is fixedly mounted on mounting base 1. Swing arm 3 is rotatably connected to support arm 2 and can rotate between a first position and a second position. Fishing net assembly 4 is mounted on swing arm 3, and fishing net assembly 4 includes fishing net 41. First power component 5 connects mounting base 1 and swing arm 3, and is configured to drive swing arm 3 to rotate from the first position to the second position, so that fishing net 41 automatically unfolds and is cast out during rotation due to inertia.

[0073] The operation of the net-catching device is as follows: Initially, the swing arm 3 is in the first position, at which point the fishing net assembly 4 is retracted into the swing arm 3. When net casting is required, the first power component 5 is activated, driving the swing arm 3 to rotate relative to the support arm 2, moving from the first position to the second position. During the rotation of the swing arm 3, the fishing net 41 moves with the swing arm 3 and gradually unfolds due to inertia; as the swing arm 3 continues to rotate to near the second position, the fishing net 41 can be released and cast out, covering the target water area. After casting is completed, the fishing net can be retrieved as needed through other mechanisms, allowing the swing arm 3 to return to the first position, preparing for the next operation.

[0074] In the above embodiment, by mounting the fishing net assembly 4 onto the swing arm 3, which is rotatable relative to the support arm 2, and driving the swing arm 3 to rotate from the first position to the second position by the first power component 5, the fishing net 41 can be unfolded and cast out by inertia during rotation, which helps to simplify the casting operation and reduce reliance on an additional release mechanism. In addition, by adjusting the output parameters of the first power component 5 (such as driving force, stroke, or movement speed), the unfolding amplitude and casting range of the fishing net 41 can be adjusted to a certain extent, thereby enhancing the adaptability of the device to different operating conditions.

[0075] The net-catching device provided in this disclosure supports both local manual operation and remote control. Users can operate the device via remote control, mobile terminal applications, etc., and in some embodiments, virtual reality (VR) or augmented reality (AR) technologies can be used to assist interaction. This setup helps lower the operational threshold and improves safety and controllability.

[0076] This disclosure simplifies the operation process and enriches the interaction, transforming traditional net-catching activities into a more engaging leisure experience. It is suitable for scenarios such as scenic spots, study bases, and family activities, thereby expanding the application possibilities of net-catching in the field of leisure and entertainment, and improving the overall user experience to a certain extent.

[0077] In some embodiments, the first power component 5 includes a linear drive device such as a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0078] In the above embodiments, the use of the above-mentioned type of drive element helps to achieve smooth and controllable rotational movement of the swing arm 3; at the same time, such power components have mature structures and reliable responses, making it easy to select the appropriate power form according to operational needs, thereby improving the adaptability and operational convenience of the net-catching device in different application environments.

[0079] In some embodiments, the support arm 2 extends vertically, the swing arm 3 is coaxial or parallel to the support arm 2 in a first position, and the swing arm 3 is substantially perpendicular to the support arm 2 in a second position.

[0080] In the above embodiments, the swing arm 3 in the first position reduces the overall space occupied by the device, facilitating storage or transportation; while in the second position, the lateral expansion of the swing arm 3 provides ample release space and movement trajectory for the fishing net 41, which is beneficial for the smooth unfolding of the fishing net under inertia. At the same time, the vertical arrangement of the support arm 2 and the rotation path of the swing arm 3 make the net casting action more in line with the natural unfolding trend under the direction of gravity, thereby improving the stability and reliability of the net casting.

[0081] In some embodiments, the fishing net assembly 4 further includes a receiving tube 42 and a plurality of net sinkers 43.

[0082] The receiving tube 42 is installed on the swing arm 3 and is configured to hold the fishing net 41. Multiple net sinkers 43 are spaced apart around the edge of the fishing net 41 after it is unfolded.

[0083] The fishing net 41 has a stored state and an unfolded state. In the stored state, the fishing net 41 and multiple net sinkers 43 are stored in the container 42. As the swing arm 3 rotates from the first position to the second position, the multiple net sinkers 43 drive the fishing net 41 from the stored state to the unfolded state and release it.

[0084] In the above embodiments, the sinker 43 refers to a counterweight component disposed at the edge of the fishing net 41, used to increase the sinking force during the casting process and assist the fishing net in unfolding. The sinker 43 can typically be made of metal, high-density polymer, or other materials with a high specific gravity, and its mass and distribution can affect the unfolding shape of the fishing net 41 and its sinking performance after entering the water.

[0085] In the above embodiments, the container 42 can effectively protect the fishing net 41 from tangling or damage when not in operation, while keeping the appearance of the device clean; while the circumferentially distributed net sinkers 43 not only provide the necessary spreading force during the casting process, but also help the fishing net 41 sink quickly after entering the water and form a stable covering shape, thereby improving the effectiveness and success rate of fishing or casting.

[0086] In some embodiments, reference Figure 4 The sinker 43 is provided with a first connecting part 433; the container cylinder 42 is provided with a second connecting part 421.

[0087] In the stored state, the fishing net 41 is located inside the container 42, and the net sinker 43 is limited to the open end of the container 42 through the cooperation of the first joint 433 and the second joint 421, thereby stably keeping the fishing net 41 in the stored state.

[0088] As the swing arm 3 rotates from the first position to the second position, the sinker 43 tends to move outward under the action of centrifugal force and / or gravity, the engagement between the first joint 433 and the second joint 421 is released, and the fishing net 41 is released and unfolded.

[0089] In the above embodiments, the cooperation between the first connecting part 433 and the second connecting part 421 helps to reliably fix the fishing net 41 and its sinker 43 in the non-operational state, preventing the fishing net from unraveling or tangling prematurely due to transportation, movement, or accidental disturbance. At the same time, during the casting process, the connecting structure can automatically disengage at an appropriate time (such as when a predetermined speed or angle is reached), ensuring that the fishing net unfolds in the expected sequence. Thus, the reliability of the device is improved, and the controllability and consistency of the casting action are enhanced.

[0090] The first connecting part 433 and the second connecting part 421 can adopt various mating forms. For example, in some embodiments, the first connecting part 433 includes a protrusion, and the second connecting part 421 includes a groove that matches it, with the protrusion embedded in the groove to achieve a limiting fit. In other embodiments, the first connecting part 433 and the second connecting part 421 can form a magnetically attracted assembly, for example, by respectively setting a permanent magnet or magnetic material and a magnetic conductor, using magnetic force to achieve a releaseable connection. The above-mentioned mating method has a simple structure and reliable response, which can effectively fix the net sinker 43 in the stored state, and can release the fit in time according to the force situation during the rotation of the swing arm 3, thus taking into account both the stable storage and timely release requirements of the fishing net 41.

[0091] In some embodiments, reference Figure 4 The accommodating cylinder 42 includes a main cylinder 422 and multiple guide cylinders 423.

[0092] The main cylinder 422 is configured to hold the fishing net 41. A plurality of guide cylinders 423 are spaced apart on the outer periphery of the main cylinder 422, and a second joint 421 is provided on the guide cylinder 423. At least a portion of the sinker 43 can be accommodated in the guide cylinder 423.

[0093] In the above embodiment, the main cylinder 422 is used to store the fishing net 41, and each guide cylinder 423 can partially accommodate a corresponding net sinker 43. The second connecting part 421 is provided on the guide cylinder 423, for example, on its inner wall or end, and is used to cooperate with the first connecting part 433 on the net sinker 43, so as to confine the net sinker 43 within the guide cylinder 423 in the stored state.

[0094] In the above embodiment, the main cylinder 422 centrally houses the fishing net 41, while the guide cylinder 423 independently guides and positions each net sinker 43, helping to prevent the fishing net 41 from tangling during storage or release. Furthermore, integrating the second connecting part 421 onto the guide cylinder 423 integrates the connecting and guiding functions, simplifying the overall structure and improving the compactness and ease of assembly of the device.

[0095] In some embodiments, reference Figure 3 The net-catching device also includes a mounting frame 6, a first reel 7, and multiple first ropes 8.

[0096] Mounting bracket 6 is located on swing arm 3, and receiving cylinder 42 is located on mounting bracket 6.

[0097] The first retractor 7 is mounted on the mounting frame 6 and located above the receiving cylinder 42.

[0098] One end of each of the multiple first ropes 8 is connected to a sinker 43, and the other end passes through a guide tube 423 and is connected to a first reel 7.

[0099] The guide cylinder 423 is configured to guide the first rope 8, and the first reel 7 is configured to simultaneously release multiple first ropes 8 when the fishing net 41 switches from the retracted state to the unfolded state, and simultaneously reel in multiple first ropes 8 when the fishing net 41 switches from the unfolded state to the retracted state.

[0100] In the above embodiments, the cooperation between the first retractor 7 and multiple first ropes 8 enables control over the unfolding and retrieval process of the fishing net 41, which helps to improve the reliability of the casting and retrieval actions. The guide cylinder 423 is not only used to limit the sinker 43, but also serves as a guide channel for the first ropes 8, reducing the risk of friction, deviation or entanglement of the ropes during movement. Integrating the first retractor 7 into the mounting frame 6 and arranging it above the receiving cylinder 42 helps to optimize the force transmission path and make the unfolding and retrieval process smoother.

[0101] In some embodiments, reference Figure 4 The net sinker 43 includes a sinker 431 and a balance bar 432.

[0102] The sinker 431 is connected to the fishing net 41 to provide the main counterweight.

[0103] The first end of the balance bar 432 is rotatably connected to the drop body 431 via a hinge structure, while the other end is a free end that can swing relative to the drop body 431 within a certain angle range.

[0104] The first joint 433 is provided on the drop body 431 and located below the hinge structure. The first joint 433 is configured to limit the downward rotation of the balance bar 432.

[0105] Optionally, in the retracted state, the balance bar 432 can extend approximately horizontally; during net casting, as the swing arm 3 rotates and centrifugal force acts, the balance bar 432 can flip upwards, thereby assisting the edge of the fishing net 41 to unfold and providing support for stability after entering the water. After the fishing net 41 enters the water, the balance bar 432 can gradually fall back under the combined action of water flow resistance and its own weight, usually swinging downwards and returning to a position approximately horizontal, or abutting against the stop position defined by the first joint 433, thereby working with the sinker 431 to apply a uniform pulling force to the edge of the fishing net 41.

[0106] In the above embodiment, the first connecting part 433 has the following functions: firstly, in the retracted state, it cooperates with the second connecting part 421 on the receiving cylinder 42 to limit the net sinker 43 to the open end of the receiving cylinder 42; secondly, it acts as a mechanical stop to limit the downward rotation of the balance bar 432; when the balance bar 432 swings downward to contact the first connecting part 433, its further downward rotation is prevented, thereby maintaining its movement within a predetermined angle range. This structure not only achieves the dual functions of limiting and stopping through a single component, simplifying the overall structure, but also effectively improves the stability of the device in the retracted state, preventing the balance bar from excessively drooping due to gravity or disturbance, thus preventing the fishing net from tangling; during the casting process, the balance bar can be moderately extended within a controlled range to assist the fishing net edge to open evenly, avoiding unbalanced expansion caused by disordered swinging, and after entering the water, it can adaptively adjust its posture to maintain the horizontal distribution of the fishing net edge in conjunction with the sinker, thereby helping to form a stable and effective coverage area and improving the reliability and user experience of casting the net.

[0107] In some embodiments, the weight 431 is symmetrically provided with two balance bars 432 and two first connecting parts 433, that is, each balance bar 432 corresponds to one first connecting part 433, and the first connecting part 433 is located below the hinge structure. Correspondingly, the cylindrical wall of the receiving cylinder 42 is symmetrically provided with two second connecting parts 421 corresponding to each weight 43, for matching with the two first connecting parts 433, so as to achieve a double-point limiting fit in the stored state.

[0108] In the above embodiment, the symmetrical arrangement of the two balance bars 432 makes the net sinker 43 bear force evenly, which not only improves the stability of the posture when storing and prevents tilting or shaking caused by force on one side, but also helps to make the edge of the fishing net 41 spread evenly in the circumferential direction during the casting process.

[0109] In some embodiments, reference Figure 3 The net-catching device also includes a first reel 7 and multiple first ropes 8.

[0110] The first winding device 7 is located on the swing arm 3.

[0111] One end of each of the multiple first ropes 8 is connected to a sinker 43, and the other end is connected to a first reel 7.

[0112] The first reel 7 is configured to simultaneously release multiple first ropes 8 when the fishing net 41 switches from the retracted state to the unfolded state, and simultaneously reel in multiple first ropes 8 when the fishing net 41 switches from the unfolded state to the retracted state.

[0113] In the above embodiments, the centralized and synchronous control of multiple first ropes 8 by the first retractor 7 helps to achieve consistency and repeatability of the net unfolding and retrieval actions.

[0114] In some embodiments, reference Figure 3 and Figure 5 The net-catching device also includes a mounting frame 6 and multiple guide components 9.

[0115] Mounting bracket 6 is located on swing arm 3, housing cylinder 42 and first retractor 7 are both located on mounting bracket 6, and first retractor 7 is located above housing cylinder 42.

[0116] Multiple guide members 9 are provided on the mounting frame 6 and located between the receiving cylinder 42 and the first retractor 7. Each guide member 9 corresponds to a first rope 8 and is used to guide the first rope 8 to the first retractor 7.

[0117] Optionally, the guide 9 includes a guide wheel to reduce the frictional resistance of the first rope 8 during the winding and unwinding process and improve the smoothness of operation.

[0118] In the above embodiments, by integrating the housing 42, the first retractor 7, and the guide 9 onto the mounting frame 6, a compact layout and orderly guidance of the rope system are achieved. The guide 9 not only ensures that multiple first ropes 8 maintain independent and stable motion trajectories during synchronous release and retraction, but also significantly reduces direct friction between the ropes and structural components, which helps to extend service life and improve the reliability of net casting and net retrieval actions. At the same time, the vertical arrangement of the first retractor 7 above the housing 42, combined with the steering function of the guide 9, optimizes the force transmission path, making the release and retraction process more stable and efficient.

[0119] In some embodiments, reference Figure 3 and Figure 4 The net-catching device also includes a second retractor 10 and a second rope 11.

[0120] The second take-up device 10 is located on the swing arm 3, specifically, the second take-up device 10 is located on the mounting frame 6.

[0121] The second rope 11 is arranged circumferentially along the edge of the opening after the fishing net 41 is unfolded, and is connected to the fishing net 41 by multiple connectors, and one end of the second rope 11 is connected to the second reel 10.

[0122] The second retractor 10 is configured to release the second rope 11 when the fishing net 41 switches from a retracted state to an unfolded state, and to retract the second rope 11 after the netting operation is completed, so as to close the opening of the fishing net 41.

[0123] Alternatively, the connector may include a loop, a stitching tape, or a clamp, etc.

[0124] In the above embodiment, one end of the second rope 11 is connected to the second reel 10, and the remaining portion forms a closed or nearly closed loop structure surrounding the opening of the fishing net. The second reel 10 is configured to: release the second rope 11 when the fishing net 41 switches from a retracted state to an extended state, allowing it to extend along with the fishing net 41; and reel in the second rope 11 after the netting operation is completed, using circumferential tension to gradually close the opening of the fishing net 41, thereby facilitating the concentration of the catch and preventing its escape.

[0125] In the above embodiment, the active control of the opening of the fishing net 41 is achieved through the cooperation of the second retractor 10 and the second rope 11: during the casting stage, the net is allowed to fully unfold to cover the target area, and during the retrieval stage, the net opening is quickly closed by synchronously winding the rope, improving the fishing efficiency and success rate; at the same time, the second rope 11 is distributed circumferentially along the edge of the opening and fixed with multiple connection points, which helps to apply force evenly during the retrieval process, avoid local tearing or deformation, and protect the integrity of the fishing net structure; in addition, this closing mechanism can work in conjunction with the first retractor 7 to manage the unfolding / resetting of the net sinker and the opening and closing of the net opening, making the entire net casting, catching, and retrieval process more orderly and reliable.

[0126] In some embodiments, the second rope 11 is arranged circumferentially along the edge of the opening of the fishing net 41 to form a closed or nearly closed loop structure. A connecting loop is provided at one end of the loop structure, and the other end of the second rope 11 passes through the connecting loop and is connected to the second reel 10.

[0127] In some embodiments, the second retractor 10 is mounted on the mounting bracket 6. Optionally, the second retractor 10 may also be equipped with a guide for guiding the routing of the second rope 11. The second retractor 10 achieves the gathering or unfolding of the opening of the fishing net 41 by winding or releasing the second rope 11.

[0128] In other embodiments (not shown in the figures), the net-catching device also includes a plurality of first retractors and a plurality of first ropes.

[0129] Multiple first retractors are located on the swing arm 3, and each first retractor corresponds to a net sinker 43.

[0130] One end of each of the multiple first ropes is connected to the corresponding sinker 43, and the other end is connected to the corresponding first reel.

[0131] Among them, multiple first retractors are configured to release multiple first ropes when the fishing net 41 switches from a retracted state to an unfolded state, and to retract multiple first ropes when the fishing net 41 switches from an unfolded state to a retracted state.

[0132] In the above embodiments, one sinker 43 corresponds to one first reel. By equipping each sinker 43 with an independent reeling and unloading control unit, the movement state of each sinker can be precisely controlled, avoiding problems such as uneven force, asynchronous release, or retrieval jamming that may occur when multiple ropes share a single reel. During the casting process, each sinker 43 can respond independently according to its own position and centrifugal trajectory, which helps the edge of the fishing net 41 to unfold more evenly and symmetrically. During the retrieval stage, independent reeling can guide the sinkers 43 to return to their positions in an orderly manner, significantly reducing the risk of net entanglement and improving reset accuracy and operational reliability.

[0133] According to the description of the above embodiments, in the net-catching device, the net sinker 43 is connected to the first retractor 7 via the first rope 8, and its winding and unwinding are controlled by the first retractor 7; the opening edge of the fishing net 41 is provided with a second rope 11, which forms a closed or nearly closed loop structure and is connected to the second retractor 10, and its winding and unwinding are controlled by the second retractor 10.

[0134] The working process of the first retractor 7 and the second retractor 10 is as follows:

[0135] Net casting preparation stage: Both the first reel 7 and the second reel 10 are in the release state, allowing the first rope and the second rope 11 to be released freely.

[0136] Net deployment stage: Due to the high-speed rotation and sudden braking of the swing arm 3, the sinker 43 is thrown out under the action of inertial force, which drives the fishing net 41 to quickly unfold and be thrown into the target waters, forming a covering net fishing space.

[0137] Net tightening stage: After the fishing net 41 is fully extended and the catch is completed, the second reel 10 begins to reel in the second rope 11. The contraction of the loop structure gradually closes the opening of the fishing net 41, preventing the catch from escaping.

[0138] Lifting phase: After the fishing net 41 is completely sealed, the first reel 7 and the second reel 10 reel in: the first reel 7 pulls the net sinker 43 upward; the second reel 10 keeps the net opening closed; the two work together to lift the entire fishing net 41 along with the catch to the water surface.

[0139] Unloading and Resetting Stage: After reaching the water surface, the second reel 10 reverses, releasing the second rope 11 and opening the fishing net 41, allowing the catch to fall into the harvest box 13 placed below. Then, the first reel 7 continues to reel in, pulling the net sinker 43 back to its initial storage position, completing the device reset and preparing for the next operation.

[0140] In some embodiments, reference Figure 1 The net-catching device also includes a support carrier 12, a harvesting box 13, and a second power component 14.

[0141] Mounting base 1 is rotatably mounted on support carrier 12. Harvest box 13 is mounted on support carrier 12 and is used to receive the catch caught by fishing net 41. Second power unit 14 is mounted on support carrier 12 and is connected to mounting base 1 for driving mounting base 1 to rotate relative to support carrier 12, so as to transfer the catch caught by fishing net 41 to harvest box 13.

[0142] In the above embodiments, the controllable rotation of the mounting base 1 is achieved by the second power component 14, so that the net casting, capture and unloading operations can be completed continuously on the same device without manual intervention or additional handling; the setting of the harvest box 13 facilitates the centralized collection of harvested materials and improves the efficiency of operation.

[0143] In some embodiments, the second power component 14 includes a motor. The motor is mounted on the support carrier 12, and its output shaft is connected to the mounting base 1 for driving the mounting base 1 to rotate relative to the support carrier 12.

[0144] In some embodiments, the support carrier 12 may be a mobile carrier such as a water-mobile buoyancy platform with an electric propulsion system, a land-mobile support platform, or an unmanned aerial vehicle pod, used to carry the entire net-catching device and achieve flexible deployment of the operating position.

[0145] In some embodiments, reference Figure 1 and Figure 2 The net-catching device also includes a support carrier 12 and a third power component 15.

[0146] Mounting base 1 is located on support carrier 12.

[0147] The third power component 15 is located on the support carrier 12 and is configured to drive the support carrier 12 to rotate in order to adjust the working position of the fishing net 41.

[0148] In the above embodiment, the third power component 15 is disposed on the support carrier 12 and is configured to drive the support carrier 12 to rotate relative to the ground, water surface or air environment, thereby adjusting the working position of the fishing net 41 (such as orientation, horizontal angle, etc.) to adapt to the needs of different fishing areas or target directions.

[0149] In some embodiments, the net-catching device further includes a detection component 17 and a control component 16.

[0150] The detection component 17 is located on the carrier 12 and is configured to detect the distribution information of target organisms suitable for net trapping in the water.

[0151] The control component 16 is electrically connected to the detection component 17 and the first power component 5. It is configured to receive external operation commands and send control commands to the first power component 5 to drive the first power component 5 to rotate the swing arm 3 from the first position to the second position, so that the fishing net 41 automatically unfolds and is cast out by inertia during the rotation.

[0152] In the above embodiments, the detection component 17 is used to detect target organisms such as fish in the water, obtain their location, density or activity area and other distribution information, and assist the user in accurately judging the timing and direction of net casting; the control component 16 is used to convert the operation intention into mechanical action, which significantly improves the targeting and success rate of net casting; at the same time, the first power component 5 drives the swing arm 3 to rotate at high speed to release the fishing net 41, ensuring that the deployment process is stable and reliable.

[0153] In some embodiments, the control component 16 may include a human-machine interface, which includes at least one of the following:

[0154] A touchscreen is used to display images of the water area and receive instructions to cast nets.

[0155] The wireless remote control module communicates with the mobile terminal to receive control signals.

[0156] The physical button group includes a net-throwing button and a reset button.

[0157] In some embodiments, the human-machine interface can be a touch screen mounted on the device body. The touch screen can display in real time a heat map of fish distribution or underwater images acquired by the detection component 17; the user can send a start command to the control component 16 by clicking the "cast net" icon on the interface, thereby driving the first power component 5 to rotate the swing arm 3 and complete the net casting action.

[0158] In other embodiments, the human-machine interface establishes a communication connection with the user's mobile terminal (e.g., smartphone or tablet) via a wireless remote control module (such as a Bluetooth or Wi-Fi module). The user can remotely view underwater images or target organism distribution information transmitted by the detection component 17 through a dedicated application (App), and trigger a net-casting command on the App interface to achieve long-distance, non-contact operation.

[0159] In some embodiments, the detection component 17 may include a camera and / or a sonar detector for acquiring underwater visual images or acoustic echo signals to identify the location and distribution of target organisms.

[0160] In some embodiments, the net-catching device may further include a fish-attracting component, which may include one or more combinations of a sonic fish attractor, a bait dispenser, a fish-attracting lamp, and a fish-attracting sachet. Furthermore, the fish-attracting component may also be equipped with a temperature sensor and / or a coordinate sensor, etc.

[0161] refer to Figure 1 and Figure 2 In some embodiments, the support carrier 12 may include a pontoon 121 and a water divider 122. The pontoon 121 constitutes the main body of the support carrier 12 and is used to provide buoyancy; the water divider 122 is located at the front end of the pontoon 121 and is used to reduce navigation resistance or improve water flow stability.

[0162] In some embodiments, the third power unit 15 may include an electric thruster (e.g., an electrically driven propeller), which is mounted on both sides of the bottom of the support carrier 12 for driving the device to travel and turn on the water surface.

[0163] In some embodiments, the interior of the float 121 may also include a sealed compartment for housing the battery 20. The battery 20 can be used to provide power to the third power unit 15, the control assembly 17, and other electrical components.

[0164] In some embodiments, such as Figure 1 As shown, a plurality of pillars 18 (e.g., four pillars 18) are spaced apart on the support carrier 12, and the upper ends of the plurality of pillars 18 are connected to and support a bracket 19; the mounting base 1 is rotatably mounted on the bracket 19, and the second power component 14 is mounted on the bracket 19 to drive the mounting base 1 to rotate relative to the bracket 19.

[0165] In some embodiments, the net-catching device can also be used in conjunction with a remote operation terminal, which includes smart glasses with visual display and voice control functions.

[0166] Once the fishing net 41 has completed its catch, the remote operator can view the images transmitted back by the detection component 17 in real time through smart glasses and remotely control the net-catching device to move to the designated retrieval position. Subsequently, the remote operator can control the swing arm 3 to rotate and lift the fishing net 41 via voice commands or interface input; or on-site personnel can use lifting equipment to lift the entire fishing net assembly.

[0167] After the fishing net 41 is raised to a suitable height, the staff places the harvest box 13 below the fishing net 41. The remote operator then confirms the alignment through smart glasses and sends a command through the control component 16 to reverse the second reel 10, releasing the second rope 11, thereby opening the opening of the fishing net 41 and allowing the harvest to fall into the harvest box 13.

[0168] Finally, remote operators can use smart glasses to combine image data from the detection component 17 to remotely assess the quantity and quality of the harvest, assisting in subsequent decision-making.
