[0002] We know that fishing is a popular recreational activity, and various fishing and catching equipment are also highly sought after by these people. Among them, the more powerful fishing boats on the market can perform baiting and can be used with underwater cameras for remote monitoring to observe the underwater environment. However, the functions of fishing boats are quite limited, generally only having the function of baiting; when a school of fish is observed through the underwater camera, it cannot be used to catch the fish. If a multi-functional fishing activity involving baiting, fishing, and observation is to be carried out, several fishing equipment need to be used in combination; however, the coordination between various fishing equipment is also complex, inconvenient to use, and time-sensitive.
[0003] It is evident that existing fishing equipment suffers from problems such as limited functionality and complex operation. Summary of the Invention
[0004] In view of this, the main purpose of this utility model is to provide a fishing system that is relatively complete in function, easy to use, and highly intuitive and interesting.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] Figure 1 This is a schematic diagram of the overall structure of the fishing system described in this utility model. Figure 1As shown, the fishing system of this utility model includes: a shore-based operation unit 1 for human-computer interaction, processing and displaying underwater environment data sent by the underwater operation unit 2, sending operation commands to the underwater operation unit 2, displaying underwater alarm signals, and providing power to the shore-based operation unit 1 and the underwater operation unit 2; and a shore-based operation unit 1 for collecting surrounding video images and fish information of the underwater operation unit 2 while it is underwater, performing baiting and attracting fish and shooting fish according to the operation commands sent by the shore-based operation unit 1, identifying and alarming fish schools and fish conditions, and sending the collected video images and fish information to the underwater operation unit 2 of the shore-based operation unit 1; wherein, the underwater operation unit 2 is buoyant and movable; the shore-based operation unit 1 and the underwater operation unit 2 are connected by wires.
[0020] In this invention, the operating instructions include: sinking and floating instructions, movement instructions, baiting and attracting fish instructions, and shooting fish instructions.
[0021] In summary, the fishing system described in this utility model monitors the underwater situation through an underwater operating unit, while the onshore operating system displays the underwater situation in real time and issues commands through human-computer interaction. The underwater operating unit can also identify fish schools and fish activity; when it detects a school or activity, it will issue an alarm signal, which will be displayed on the onshore operating unit. Onshore fishermen, based on the underwater situation and alarm signals observed by the onshore operating unit, send commands for baiting and shooting fish to the underwater operating unit through human-computer interaction. In conclusion, the fishing system described in this utility model is fully functional, easy to use, and highly intuitive and engaging.
[0022] In this invention, the underwater operation unit 2 includes: a sealed chamber that moves up and down and forward and backward according to the buoyancy or movement commands sent by the shore operation unit 1; a camera for transmitting collected underwater surrounding video images to the shore operation unit 1 and the underwater information processing module; a detection module for transmitting collected underwater fish information to the shore operation unit 1 and the underwater information processing module; an underwater information processing module for filtering, identifying fish schools, and processing the surrounding video images and fish information transmitted by the camera, and sending fish school confirmation information or fish condition confirmation information to the shore operation unit 1 and the underwater alarm module; an underwater alarm module for generating an alarm signal after receiving fish school confirmation information or fish condition confirmation information sent by the underwater alarm module, and sending the alarm signal to the underwater alarm module of the shore operation unit 1; a baiting and attracting module for baiting and attracting fish according to the baiting and attracting commands sent by the shore operation unit 1; and a shooting and restraining module for throwing and pulling fish darts at the target fish according to the shooting commands sent by the shore operation unit 1.
[0023] The camera is installed in the middle of the outer front of the sealed chamber, and the detection module is installed in the upper outer front of the sealed chamber. The underwater information processing module and the underwater alarm module are both installed inside the sealed chamber. Part of the fish shooting and restraining module is installed inside the sealed chamber, and the other part is installed outside the sealed chamber. The baiting and fish attracting module is installed at the front of the sealed chamber.
[0024] The camera is connected to the underwater information processing module, the detection module is connected to the underwater information processing module, and the underwater information processing module is connected to the underwater alarm information module via wires.
[0025] In this utility model, the onshore operation part 1 and the underwater operation part 2 are connected by wires. Specifically, the onshore operation part 1 is connected to the camera, the detection module, the underwater alarm module, the information processing module, the baiting and fish-attracting module, and the fish-shooting and restraining module by wires.
[0026] In practical applications, the video images around the underwater operating unit 2 detected by the camera contain information about surrounding fish and obstacles. However, because the camera is underwater, its detection capabilities are limited; therefore, the video images it acquires only display environmental information within a 3-5 meter area in front of the underwater operating unit 2. The detection module detects fish activity information in areas further away than 5 meters, and it can also detect water depth and temperature. Here, fish activity information includes the location and size of the fish schools.
[0027] In practical applications, the fishing system described in this utility model can be used for shooting fish in freshwater and for fishing in seawater. When applied to seawater fishing, it can be used for sea fishing and for stunning fish that have already taken the bait. If stunning fish already taken the bait is to be fished, the operating instructions transmitted by the shore-based operating unit 1 should also include instructions to stun the fish. The underwater operating unit 2 should also include a high-voltage module that sends a certain current to the fish based on the instructions from the shore-based operating unit 1 to stun the fish. The high-voltage module should be installed inside the sealed chamber and connected to the shore-based operating unit 1 via a wire. The current output of the high-voltage module can be controlled according to the size of the fish, but the basic principle is to stun the fish.
[0028] In this invention, the onshore operation module, detection module, underwater alarm module, information processing module, baiting and fish-attracting module, and high-voltage module are all existing technologies and will not be described in detail here.
[0029] In practical applications, the baiting and fish-attracting module can also carry fishing hooks.

Figure 3This is a top view of the sealed chamber, the fish-shooting and restraining module described in this utility model. Figure 4 This is a front view of the sealed chamber, the fish-shooting and restraining module described in this utility model. Figure 5 This is a side view of the sealed chamber, fish-shooting and restraining module described in this utility model. Figures 2-5 As shown, in this utility model, the sealed chamber includes: an outer shell 21 for forming the chamber body; a buoyancy mechanism for adjusting the air volume inside the sealed chamber to achieve buoyancy; two propellers 23 for pushing and pulling the sealed chamber to move back and forth; a front sealing cover 24 for sealing the front end of the sealed chamber; and an upper sealing cover 26 for sealing the upper end of the sealed chamber; wherein,
[0031] The buoyancy mechanism is installed in the middle of the sealed chamber; two propellers 23 are respectively installed on the rear side of the outside of the sealed chamber, and the two propellers are symmetrical about the left and right sides of the sealed chamber.
[0032] In practical applications, the two propellers 23 control the forward and backward movement of the sealed chamber via motors and their control systems. The motors and control systems are existing technologies and will not be described in detail here.
[0033] In practical applications, the buoyancy mechanism includes: a piston for changing the air volume inside the sealed chamber by moving up and down; a push-pull rod for driving the piston up and down; and a buoyancy control unit for driving the push-pull rod; wherein the buoyancy control unit is installed inside the sealed chamber.
[0034] The piston is installed in a piston cylinder on the lower side of the middle of the outer casing 21. One end of the push-pull rod is fixedly connected to the piston, and the other end of the push-pull rod is connected to the buoyancy control unit. Here, the buoyancy control unit can be hydraulically controlled or electrically controlled. Both hydraulic and electric control are existing technologies and will not be described in detail here.
[0035] In practical applications, a through hole is provided at the upper end of the piston cylinder on the lower side of the outer casing 21. The push-pull rod passes through this through hole and is fixedly connected to the piston, and a sealing ring is installed on the through hole. When the buoyancy control unit drives the push-pull rod to move upward, the push-pull rod also drives the piston to move upward along the piston cylinder on the lower side of the outer casing 21. This process compresses the air in the sealed chamber, reducing its volume, and causing the sealed chamber to sink in the water. When the buoyancy control unit drives the push-pull rod to move downward, the push-pull rod also drives the piston to move downward along the piston cylinder on the lower side of the outer casing 21. This process increases the volume of air in the sealed chamber, causing the sealed chamber to float in the water.
[0036] In this invention, the fish-shooting and restraining module includes: two dart tubes 27 for holding fish darts 28, two fish darts 28 for shooting fish, and two fish dart launching and restraining mechanisms 29. Each dart tube 27 holds one fish dart 28, and one fish dart 28 or one dart tube 27 corresponds to one fish dart launching and restraining mechanism 29.
[0037] Two dart tubes 27 are symmetrically installed on the outside of the top of the sealed chamber. Two dart launching and traction mechanisms 29 are installed on the outer shell 21 and the corresponding dart tubes 27. For each dart launching and traction mechanism 29, one part is located inside the corresponding dart tube 27, another part is located between the corresponding dart tube 27 and the outer shell 21, and the third part is located inside the outer shell 21.

Figure 7 This is a front view of the fish-shooting and restraining module described in this utility model inside the outer shell.

The system includes: a stop pin A15 for limiting the firing shaft A11; a second bearing A16 for reducing wear between the stop pin A15 and the inclined surface of the sleeve A14; a first screw A17 for fixing the other end of the firing rope A4; wherein the electromagnetic control unit A1 is connected to the shore operation part 1 via a wire; the first screw A17 is fixed to the fan-shaped balance wheel A6; the other end of the firing rope A4 passes through the first bearing A9 and the fan-shaped balance wheel A6 in sequence and is fixed to the first screw A17;
[0039] One end of the movable slide bar A2 is located inside the electromagnetic control unit A1, and the other end of the movable slide bar A2 is a free end. The retaining ring A5 is fixed to the free end side of the movable slide bar A2, and one end of the firing rope A4 is also fixed to the free end of the movable slide bar A2. The conical spring A3 is sleeved on the outside of the movable slide bar A2 and installed between the retaining ring A5 and the electromagnetic control unit A1.
[0040] The boss A8 is fixed to the inner wall of the outer casing 21, and the first bearing A9 is sleeved on the column on the boss A8; one end of the transmission rod A12 passes through the outer casing 21, and a sleeve is also provided between the transmission rod A12 and the outer casing 21, through which the transmission rod A12 passes; the sleeve is fixed inside the outer casing 21 by a first nut A7, and one end of the transmission rod A12 passes through a sector-shaped swing wheel A6, which can drive the transmission rod A12 to rotate; the sleeve is fixed outside the outer casing 21 by another first nut A7, and a... There is a sealing ring, and two O-rings are also installed between the transmission rod A12 and the sleeve section; the other end of the transmission rod A12 is fixedly connected to the firing shaft A11; the first spring A13 is sleeved on the outside of the transmission rod A12 and installed between the firing shaft A11 and the first nut A7 on the outside of the outer casing 21; a stop pin A15 is welded to the lower middle part of the side of the firing shaft A11, and the second bearing A16 is installed on the stop pin A15; a through hole is opened in the dart tube 27, and a sleeve A14 is welded to the outside of the dart tube 27 at the through hole, and the firing shaft A11 passes through the sleeve A14 and the through hole.
[0041] In practical applications, the dart tube 27, in addition to housing the dart 28, also houses a second spring, a spring sleeve for the second spring, and fishing line. The inner wall of the dart tube 27 is also equipped with a fixing mechanism for securing the fishing line and one end of the second spring. One end of the second spring is fixed to the dart tube 27 via the spring fixing mechanism, while the other end is fixed inside the spring sleeve. One end of the fishing line is fixed to the tail end of the dart 26, and the other end is fixed to the fishing line fixing mechanism.
[0042] In practical applications, the transmission rod A12 and the firing shaft A11 can be a single integrated structure.
[0043] In practical applications, within the harpoon tube 27, when the harpoon 28 is in its initial state, the outer side of the tail end of the harpoon 28 abuts against the spring sleeve, the second spring is compressed, and the firing shaft A11 abuts against the front end of the spring sleeve, with the tail end of the harpoon 28 also abutting against the front end of the spring sleeve. Simultaneously, the first spring A13 is in its natural state. When the fishing and restraint module receives the fishing command sent by the shore operation unit 1, the electromagnetic control unit A1 is de-energized, the conical spring A3 is released, and the firing rope A4 drives the fan-shaped pendulum wheel A6 to rotate forward. The rotating fan-shaped pendulum wheel A6 then sequentially drives the transmission rod A12 and the firing shaft A11 to rotate forward, causing the trip pin A15 on the firing shaft A11 to rotate downward along the inclined surface of the lower end of the sleeve A14. The downward rotating trip pin A15 drives the firing shaft A11 to rotate downward as well, until the firing shaft A11 no longer abuts against the front end of the spring sleeve; simultaneously, the first spring A13 is compressed. When the spring sleeve disengages from the firing shaft A11, the harpoon 28 is launched from the harpoon tube 27 under the force of the second spring. Since the harpoon A8 is pulled by the fishing line, both the harpoon A8 and the fish hit by the harpoon can be retrieved. During this process, under the forward rotation of the fan-shaped balance wheel A6, the catch pin A15 on the firing shaft A11 and the lower inclined surface of the sleeve A14 form a limiting rotation. This limiting rotation is downward, which converts the rotational motion of the transmission rod A12 into the downward motion of the firing shaft A11. After being energized, the electromagnetic control unit A1 controls the sliding rod A2 to move downward, compresses the conical spring A3, and causes the firing rope A4 to drive the fan-shaped balance wheel A6 to rotate in the opposite direction. The rotating sector-shaped balance wheel A6 sequentially drives the transmission rod A12 and the firing shaft A11 to rotate in opposite directions. This causes the catch pin A15 on the firing shaft A11 to rotate upwards along the inclined surface at the lower end of the sleeve A14. The upward rotation of the catch pin A15 drives the firing shaft A11 to rotate upwards as well, until the firing shaft A11 finally abuts against the front end of the spring sleeve. Simultaneously, the second spring is compressed, and the first spring A13 is gradually released to a free state. During the above process, under the reverse rotation of the sector-shaped balance wheel A6, the catch pin A15 on the firing shaft A11 and the inclined surface at the lower end of the sleeve A14 still form a limiting rotation. This limiting rotation is upward, which converts the rotational motion of the transmission rod A12 into the upward motion of the firing shaft A11. In summary, the limiting rotation of the catch pin A15 in conjunction with the inclined surface at the lower end of the sleeve A14 converts the rotational motion of the transmission rod A12 into the linear motion of the firing shaft A11.
[0044] In practical applications, the fishing system also includes two pairs of arc-shaped fastening strips 20 for fixing the dart tube 27 to the outer casing 21. Each pair of arc-shaped fastening strips 20 forms a fastening pair. One fastening pair is attached to the front outer wall of the sealed chamber, and the upper and lower ends of the fastening pair are each fixed by a screw. The other fastening pair is attached to the rear outer wall of the sealed chamber, and the upper and lower ends of the other fastening pair are also each fixed by a screw.
[0045] In practical applications, the electromagnetic control unit A1 is existing technology and will not be described in detail here.
[0046] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
