Description

Technical Field

[0001] This utility model relates to the field of underwater biological monitoring technology, and in particular to an underwater fish face collection device. Background Technology

[0002] Fish information is crucial for various aquaculture management activities, such as feeding decisions, grading optimization, sales timing, fish stocking density and dissolved oxygen consumption calculations, and antibiotic dosage. Therefore, accurate identification of individual fish is of great significance for improving the efficiency of aquaculture management.

[0003] However, at present, most fish identification methods are done manually. Operators need to use handheld RFID terminals for contact measurement, but this method is greatly affected by subjectivity and requires a high level of technical skill from the operators. At the same time, this method is labor-intensive and inefficient. In addition, because the measurement is time-consuming, it may cause stress to the fish and even lead to dehydration and death. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an underwater fish face acquisition device to solve the technical problem of low efficiency in existing fish information acquisition technologies.

[0005] To achieve the above objectives, this utility model provides an underwater fish face acquisition device for collecting fish information when placed in water, comprising:

[0006] The box has a measuring lane inside, and the outside of the box has at least one opening that connects to the measuring lane inside, so that fish can swim into the measuring lane from the opening and stabilize their posture.

[0007] At least one information acquisition component is connected to the housing. The information acquisition component is used to collect information about fish entering the measurement lane. In use, the acquisition device is placed in the water, and fish bait placed in the measurement lane is used to induce fish to swim into the measurement lane from the opening, thereby cooperating with the information acquisition component to collect information about the fish.

[0008] As a preferred embodiment of this utility model, the opening has two parts and is respectively located at the top and bottom of the box.

[0009] As a preferred embodiment of this utility model, the information acquisition component includes:

[0010] A first camera assembly is disposed on the opening at the top, the first camera assembly being used to capture images of fish faces in the swimming lane from top to bottom;

[0011] A second camera assembly is provided on the side of the enclosure, which is used to photograph and measure fish in the swimming lane from the side through the enclosure.

[0012] As a preferred technical solution of this utility model, the collection device further includes several supports disposed on the surface of the box to provide high support for it, so that the opening at the top protrudes above the water surface and the opening at the bottom is separated from the placement surface.

[0013] As a preferred embodiment of this utility model, the acquisition device further includes an adjustment mechanism for adjusting the support height of the bracket, the adjustment mechanism comprising:

[0014] A guide rail is fixedly installed on the outside of the housing, and the bracket is slidably installed in the guide rail. A first threaded groove is opened on the surface of the guide rail, and a plurality of second threaded grooves are opened at intervals on the side of the bracket facing the first threaded groove.

[0015] A positioning bolt used to simultaneously connect the first threaded groove and the second threaded groove.

[0016] As a preferred technical solution of this utility model, a transparent observation window is provided on the side of the box to facilitate the lens of the second camera component to photograph and measure the fish in the swimming lane.

[0017] As a preferred embodiment of this utility model, the exterior of the housing is provided with:

[0018] A first fixing mechanism for fixing the first camera component to the top opening;

[0019] A second fixing mechanism for securing the second camera component to the transparent viewing window.

[0020] As a preferred embodiment of this utility model, the first fixing mechanism includes:

[0021] A mounting bracket with one end fixedly connected to the back of the housing;

[0022] A slide rail that is fixedly connected at one end to the mounting bracket;

[0023] Two sliders disposed in the slide rail slide relative to each other.

[0024] A clamping member is fixedly connected to the slider, and the surface of the clamping member is provided with a clamping groove that is adapted to the shape of the first camera component;

[0025] Rotating the bidirectional lead screw located in the slide rail, the bidirectional lead screw cooperates with the lead screw groove opened on the surface of the slider. By rotating the bidirectional lead screw, the two sliders can be driven to move towards each other or away from each other, thereby causing the clamping member to clamp or release the first camera component.

[0026] As a preferred embodiment of this utility model, the second fixing mechanism includes:

[0027] A fixing block fixedly installed on the side of the box body;

[0028] The rotating shaft is rotatably connected to the fixed block;

[0031] The beneficial effects of this utility model are as follows: By setting a measuring lane in the tank and combining it with a fish bait induction mechanism, fish can swim into the measuring lane through the opening. After stabilizing the fish's posture using the measuring lane, the fish's body information is automatically collected by the information acquisition component. This eliminates the need for manual handheld terminal contact measurement, reduces the technical difficulty of measurement, shortens the measurement time, avoids fish emergency reactions, and effectively improves information acquisition efficiency.

[0040] 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 specific embodiments.

[0041] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0042] like Figure 1 As shown, an underwater fish face acquisition device is used to collect information about fish when placed in water. It includes: a housing 1 with a measurement lane 3 inside, and at least one opening 2 on the outside of the housing 1 communicating with the internal measurement lane 3, allowing fish to swim into the measurement lane 3 through the opening 2 and maintain a stable posture; and at least one information acquisition component connected to the housing 1, which is used to collect information about the fish entering the measurement lane 3. In use, the acquisition device is placed in the water, and bait placed in the measurement lane 3 is used to induce fish to swim into the measurement lane 3 through the opening 2, thereby cooperating with the information acquisition component to collect fish information.

[0043] The above-mentioned technical solution can efficiently collect fish information. In use, the bait is placed in the box 1, and then the box 1 is placed in the water, ensuring that the opening 2 is unobstructed. The bait attracts the fish, and the fish swims into the measuring lane 3 in the box 1 through the opening 2. The information collection component collects the fish's information. Therefore, this utility model, by setting the measuring lane 3 in the box 1 and combining it with the bait induction mechanism, allows the fish to swim into the measuring lane 3 through the opening 2. After stabilizing the fish's posture using the measuring lane 3, the information collection component automatically collects the fish's body information. There is no need for manual handheld terminal contact measurement, which reduces the technical difficulty of measurement and shortens the measurement time. It can also avoid the fish's emergency reaction and effectively improve the information collection efficiency.

[0044] like Figure 1 and Figure 3 As shown, in this embodiment, there are two openings 2, which are respectively located at the top and bottom of the box body 1;

[0045] The above technical solution can collect information on special fish species. For example, groupers do not eat fixed bait but only flowing bait. In this case, the bait needs to be scattered into the measuring channel 3 from the top opening 2. The flowing bait induces the groupers to swim into the measuring channel 3 from the bottom opening 2.

[0046] Furthermore, in this embodiment, the box 1 is equipped with an automatic fish feeder that can automatically sprinkle fish bait from the top opening 2 into the measuring lane 3;

[0047] The above technical solution can automatically distribute fish bait, which can further improve efficiency and save manpower. Automatic fish feeders are existing technologies and can be purchased on the market, so they will not be described in detail here.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the information acquisition component includes: a first camera component 4 disposed on the opening 2 at the top, the first camera component 4 being used to photograph the fish face in the measurement lane 3 from top to bottom; and a second camera component 5 disposed on the side of the box 1, the second camera component 5 being used to photograph the fish body in the measurement lane 3 from the side through the box 1.

[0049] The above technical solution can capture the fish's face and body through the camera components. The first camera component 4 and the second camera component 5 are waterproof cameras. The second camera component 5 can be a 1-megapixel 720P dual-lens synchronous camera.

[0050] like Figure 1 and Figure 3As shown, in this embodiment, the collection device also includes several supports 6 disposed on the surface of the box 1 to provide high support for it, so that the top opening 2 protrudes above the water surface and the bottom opening 2 is separated from the placement surface.

[0051] The above technical solution can ensure that the fish bait is accurately thrown into the measuring channel 3. Since the top opening 2 is exposed above the water surface, when the fish bait is thrown into the top opening 2, the fish bait will be blocked by the inner wall of the measuring channel 3, preventing the fish bait from leaving the measuring channel 3 and thus failing to effectively induce the fish to enter the measuring channel 3. The bottom opening 2 is separated from the placement surface, which makes it convenient for the fish to enter.

[0052] like Figure 3 and Figure 5 As shown, in this embodiment, the acquisition device further includes an adjustment mechanism for adjusting the support height of the bracket 6. The adjustment mechanism includes: a guide rail 19 fixedly disposed on the outside of the housing 1, the bracket 6 slidably disposed in the guide rail 19, a first threaded groove 20 being formed on the surface of the guide rail 19, and a plurality of second threaded grooves 22 being formed at intervals on the side of the bracket 6 facing the first threaded groove 20; and a positioning bolt 21 for simultaneously connecting the first threaded groove 20 and the second threaded groove 22.

[0053] The above technical solution can adjust the height of the box 1. In use, rotate the positioning bolt 21 to disengage it from the second threaded groove 22 on the surface of the bracket 6, thereby releasing the sliding limit on the bracket 6. By sliding the bracket 6, it can move relative to the guide rail 19, thereby adjusting the support height. When the bracket 6 slides to the desired position and the second threaded groove 22 is aligned with the first threaded groove 20, tighten the positioning bolt 21 to connect the second threaded groove 22 and the first threaded groove 20 at the same time, thus completing the height adjustment of a single bracket 6. This device has a total of four brackets 6. By following the above steps to adjust the remaining three brackets 6, the height of the box 1 can be adjusted.

[0054] like Figure 3 As shown, in this embodiment, a transparent observation window 15 is provided on the side of the box 1 so that the lens of the second camera assembly 5 can capture images of the fish in the swimming lane 3.

[0055] The above technical solution allows the second camera component 5 to easily capture images of the fish in the swimming lane 3 from the side.

[0056] like Figure 3 As shown, in this embodiment, the exterior of the housing 1 is provided with: a first fixing mechanism for fixing the first camera assembly 4 to the top opening 2; and a second fixing mechanism for fixing the second camera assembly 5 to the transparent observation window 15.

[0057] The above technical solution can fix the first camera component 4 and the second camera component 5 to the outside of the box 1, thereby taking pictures of the fish from two different angles.

[0058] like Figure 4 As shown, in this embodiment, the first fixing mechanism includes: a mounting bracket 7 with one end fixedly connected to the back of the housing 1; a slide rail 8 with one end fixedly connected to the mounting bracket 7; two sliders 9 slidably disposed in the slide rail 8; a clamping member 10 fixedly connected to the sliders 9, the surface of the clamping member 10 having a clamping groove adapted to the shape of the first camera component 4, the surface of the clamping groove having anti-slip protrusions 11 for increasing the coefficient of friction, the anti-slip protrusions 11 being made of rubber; a bidirectional lead screw 12 rotatably disposed in the slide rail 8, the bidirectional lead screw 12 cooperating with a lead screw groove 13 on the surface of the sliders 9, one end of the bidirectional lead screw 12 passing through the slide rail 8 and connected to a handle 14, by rotating the bidirectional lead screw 12 can drive the two sliders 9 to move towards each other or away from each other, thereby driving the clamping member 10 to clamp or release the first camera component 4;

[0059] The above technical solution can fix the first camera component 4 by clamping. In use, the first camera component 4 is placed between the two clamping members 10. Rotating the handle 14 in the first direction can drive the bidirectional lead screw 12 to rotate, thereby driving the two sliders 9 to move towards each other along the slide rail 8, thereby causing the clamping members 10 to clamp the first camera component 4. When it is necessary to disassemble the first camera component 4, rotating the handle 14 in the second direction opposite to the first direction can drive the two clamping members 10 to release the first camera component 4 through the bidirectional lead screw 12. In this embodiment, the first camera component 4 is cylindrical in shape, so the clamping groove on the surface of the clamping member 10 is arc-shaped, which can better fit the first camera component 4. The relatively soft anti-slip protrusions 11 can play an anti-slip role, preventing the first camera component 4 from falling off, while ensuring that the first camera component 4 will not be deformed by clamping.

[0060] like Figure 1 and Figure 3 As shown, in this embodiment, the second fixing mechanism includes: a fixing block 17 fixedly disposed on the side of the housing 1; a rotating shaft 18 rotatably connected to the fixing block 17; and a cover 16 fixedly connected to both ends of the rotating shaft 18, the inside of which forms a chamber for accommodating the second camera assembly 5; a rubber ring is provided between the rotating shaft 18 and the fixing block 17 to increase the damping during rotation and prevent the cover 16 from opening due to accidental contact.

[0061] The above technical solution allows the second camera component 5 to be installed on the side of the housing 1. During installation, the camera of the second camera component 5 is aligned with the transparent observation window 15 and embedded. Then, the cover 16 is rotated around the pivot 18, thereby covering the second camera component 5 through the cover 16 and completing the installation.

[0062] The detailed dimensions and specifications of this device are as follows:

[0063] 1. The box body 1 is 40cm long and wide, the measuring lane 3 is cylindrical and 30-60cm long, and the overall height of the device is 1m;

[0064] 2. The cross-section of opening 2 is rectangular;

[0065] 3. The sidewalls of measuring lane 3 are made of transparent material to facilitate external observation, such as glass or plastic;

[0066] 4. The cross-section of opening 2 is larger than the cross-section of measuring lane 3, so that fish can swim into measuring lane 3 from the larger opening 2. At the same time, the smaller measuring lane 3 is conducive to the stability of the fish's posture, making it easier for the first camera component 4 and the second camera component 5 to capture images.

[0067] Working principle: When in use, first adjust the overall height of the device, rotate the positioning bolt 21 to disengage it from the second threaded groove 22 on the surface of the bracket 6, thereby releasing the sliding limit on the bracket 6. By sliding the bracket 6, it can move relative to the guide rail 19, thereby adjusting the support height. When the bracket 6 slides to the desired position and the second threaded groove 22 is aligned with the first threaded groove 20, tighten the positioning bolt 21 to connect the second threaded groove 22 and the first threaded groove 20 at the same time. Follow the above steps to complete the adjustment of the remaining three brackets 6, thereby realizing the height adjustment of the tank 1, so as to ensure that the opening 2 at the top of the tank 1 is exposed above the water surface after it is placed in the water.

[0068] Then install the first camera assembly 4 and the second camera assembly 5. Place the first camera assembly 4 between the two clamping members 10. Rotate the handle 14 in the first direction to drive the bidirectional lead screw 12 to rotate, thereby driving the two sliders 9 to move towards each other along the slide rail 8, thereby driving the clamping members 10 to clamp the first camera assembly 4. Align the camera of the second camera assembly 5 with the transparent observation window 15 and embed it. Then rotate the cover 16 to make it rotate around the rotating axis 18, thereby covering the second camera assembly 5 through the cover 16 to complete the installation.

[0069] Fish bait is scattered into the measuring lane 3 through the opening 2 at the top of the tank 1. After the fish bait is scattered into the opening 2, it will be blocked by the inner wall of the measuring lane 3, preventing the fish bait from leaving the measuring lane 3 and thus failing to effectively induce the fish to enter the measuring lane 3. The fish bait attracts the fish, and the fish swims into the measuring lane 3 in the tank 1 through the opening 2. The measuring lane 3 helps stabilize the fish's posture. The first camera component 4 takes pictures of the fish's face, while the second camera component 5 takes pictures of the fish's body through the transparent observation window 15. It should be noted that this device is only used to collect information about the fish, and information analysis and processing will be carried out in subsequent stages.
