Description

Technical Field

[0001] This utility model relates to the field of experimental research technology on fish behavior, specifically an experimental research tank device for monitoring the migratory behavior of parent fish. Background Technology

[0002] Migration is a long-distance, directional migration behavior undertaken by fish during their life cycle for purposes such as reproduction, foraging, or overwintering. It is an important ecological strategy for fish to adapt to environmental changes and maintain population continuity. Water temperature and current are considered key environmental factors influencing fish migration behavior, especially significantly driving the upstream migration of parent fish. Currently, most related research relies on indoor aquarium simulation experiments, constructing controlled water flow and temperature environments to observe the upstream behavioral responses of fish.

[0003] Although existing technologies have developed various experimental devices for studying fish migration behavior, the following shortcomings still exist: The monitoring angle is limited, and there are blind spots.

[0004] Traditional devices often use fixed cameras, which can only capture images from a single angle (usually overhead or side view). Since experimental tanks are mostly linear or large static pools, the placement of cameras is limited and cannot cover the entire tank area. This results in the lack of recording of fish behavior at the edges, bottom, or corners, creating blind spots in the monitoring.

[0005] It cannot adapt to continuous observation of a circular path.

[0006] Fish migration is characterized by continuous and cyclical movement, but existing monitoring equipment lacks dynamic tracking capabilities and cannot adjust the observation perspective as the fish move, resulting in fragmented behavioral data collection. This makes it difficult to reconstruct complete migration trajectories and behavioral rhythms, leading to incomplete experimental data and affecting the accuracy and reliability of research results.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: See attached document Figures 1 to 5 An experimental research tank device for monitoring the migratory behavior of parent fish includes: A ring-shaped water tank 100 consisting of a ring-shaped steel frame and several pieces of white translucent tempered glass; A flow-generating mechanism 200 is disposed inside the annular water tank 100 and is used to agitate the water source inside the annular water tank 100. The flow-generating mechanism 200 includes at least two sets of water flow propellers 201 disposed inside the annular water tank 100 and at least two sets of protective nets 202 for protecting the fish and the water flow propellers 201. The annular water tank 100 is equipped with a flow guide grid frame 203, which is used to stabilize the turbulent water flow discharged by the propellers and stabilize the water flow direction in the tempered glass annular tank 100. At least one set of interception nets 300 are installed inside the annular water tank 100 in a detachable manner to intercept fish during the experimental research process; Temperature control system 400 is connected to annular water tank 100 via pipe; The monitoring component 500 is used to record in real time the autonomous upward movement of experimental fish in the annular tank 100. The monitoring component 500 includes a monitoring camera 501 for monitoring experimental fish, an electric guide rail 502 for adjusting the position of the monitoring camera 501, and a conversion unit 510 for adjusting the monitoring orientation of the monitoring camera 501. The monitoring camera 501 uses an industrial camera from the existing technology to record the autonomous upstream behavior of the experimental fish in the annular tank 100 in real time. The electric guide rail 502 adopts the guide rail component used in the prior art for adjusting horizontal displacement, which is used to drive the conversion unit 510 and the monitoring camera 501 to adjust the displacement, so as to realize the monitoring component 500 to monitor the annular water tank 100 at different ranges. By setting the conversion unit 510, the position of the monitoring terminal of the monitoring component 500 can be adjusted, thereby achieving full coverage of the monitoring component 500 on the annular water tank 100 in the annular state, thus ensuring the comprehensiveness of the monitoring data when the experimental fish are autonomously swimming upstream.

[0021] The annular water tank structure conforms to the migratory habits: The core of the device, the annular water tank 100, is composed of an annular steel frame and white translucent tempered glass. The annular design highly replicates the natural annular movement path of the parent fish during their migration, avoiding the restriction of migratory behavior by straight water tanks. The white translucent material facilitates observation and reduces interference from the external environment on the parent fish, making the swimming and upstream behavior of the experimental fish closer to their natural state, providing real basic data for subsequent behavioral monitoring.

[0022] Stable water flow simulates natural hydrology: The flow-generating mechanism 200 drives the water flow through at least two sets of water flow propellers 201, and, together with the flow guide grid frame 203, sorts out the turbulent water flow, ensuring that the water flow direction is stable and the flow velocity is uniform within the annular water tank 100. This can accurately simulate the water flow environment of natural water bodies such as rivers and oceans where parent fish migrate. At the same time, the protective net 202 can effectively isolate the water flow propellers 201 from the fish, preventing the equipment from causing physical damage to the parent fish and ensuring the normal activity status of the experimental fish. See attached document Figure 1 The temperature control system 400 includes a cooling and heating temperature controller, a circulating water pump, and pipeline valves; the cooling and heating temperature controller has both cooling and heating functions, and is used to pump water from the annular water tank 100 to the built-in water tank of the temperature controller for temperature adjustment. By setting the target temperature, the system automatically determines whether the water in the tank needs to be heated or cooled. The 400 temperature control system integrates a cooling and heating temperature controller, a circulating water pump, and pipeline valves, providing dual cooling and heating functions. The circulating water pump draws water from the annular water tank 100 to the temperature controller's built-in water tank. Target temperatures can be set according to experimental needs, and the system automatically determines whether to raise or lower the water temperature, achieving precise and stable temperature control. This function can meet the specific water temperature requirements of different species of parent fish, such as tropical and cold-water fish, at different growth stages and migration periods, supporting multivariate experimental studies such as the "influence of water temperature on migration behavior."

[0023] See attached document Figure 2 A guide plate 503 is fixedly connected to the movable seat of the electric guide rail 502, and a sliding block 504 that can move up and down is slidably connected inside the guide plate 503. The conversion unit 510 is mounted on the sliding block 504; when the height of the sliding block 504 is adjusted, the height can be adjusted by driving the conversion unit 510, so as to realize the adjustment of the monitoring position of the monitoring camera 501 under different height conditions. The movable base is equipped with an adjustment component for adjusting the height of the sliding block 504; The height of the sliding block 504 is adjusted by setting the adjustment component, which ultimately realizes the height adjustment of the monitoring end of the monitoring component 500. This allows for the monitoring of fish in different depths of the pool, solving the problem that existing monitoring agencies cannot understand the status of fish at different depths when using a top-down monitoring method. Note: Adjusting components include, but are not limited to, cylinders for adjusting the height of sliding block 504.

[0024] See attached document Figure 2 The adjusting component includes a lead screw 505 for adjusting the height of the sliding block 504; The top end of the lead screw 505 is rotatably connected to the top of the guide plate 503 via a bracket, and the outer surface of the lead screw 505 is threaded with a threaded block 506, and the threaded block 506 is fixedly connected to the sliding block 504 via a mounting seat. Rotation of the lead screw 505 drives the threaded block 506 to move up and down, which in turn drives the sliding block 504 to move up and down via the mounting base, ultimately achieving height adjustment of the monitoring camera 501 to meet monitoring needs at different heights. A drive motor 507 for rotating the lead screw 505 in both directions is fixedly connected to the movable base; The drive motor 507 is connected to the control system of the peripheral device. It is a reversible motor in the prior art and is set up using the existing connection and coding methods. It is used to drive the lead screw 505 to rotate in both directions, thereby realizing the height adjustment of the sliding block 504.

[0025] See attached document Figures 3 to 5 The conversion unit 510 includes a fixed base 511 fixed on the sliding block 504, an adjustment motor 512 fixed on the top of the fixed base 511, and an electric telescopic rod 513 fixedly connected to the output shaft of the adjustment motor 512 through a connecting shaft. The monitoring camera 501 is installed on the telescopic end of the electric telescopic rod 513. The adjustment motor 512 is connected to the control system of the external device. It is a reversible motor in the prior art. It is set up using the existing connection and coding methods. It is used to drive the electric telescopic rod 513 to rotate 180 degrees clockwise and counterclockwise through the connecting shaft. This can drive the monitoring camera 501 to monitor different positions of the annular water tank 100 and improve its monitoring range. The electric telescopic rod 513 is connected to an external power source and control switch to drive the monitoring camera 501 to extend and adjust, so as to realize the function of monitoring the fish in the annular water tank 100 from a top-down perspective and to monitor the fish from a top-down perspective.

[0026] See attached document Figure 3 Both sides of the fixed base 511 are fixedly connected to the support bracket 514; The support bracket 514 is used to support the connecting shaft, ensuring its stability after the connecting shaft is adjusted by 180 degrees clockwise and counterclockwise by the motor 512, and enhancing the stability of the monitoring camera 501 during operation.

[0027] Example 2: The difference from Example 1 is that; See attached document Figure 4 and Figure 5 The top of the surveillance camera 501 is hinged to the telescopic end of the electric telescopic pole 513 via a hinge bracket 515. By using a hinged frame 515 to hinge the telescopic end of the electric telescopic rod 513 to the monitoring camera 501, the monitoring end of the monitoring camera 501 can be naturally vertical downwards by gravity. Even when the monitoring camera 501 in this position is switched to the other side by adjusting the motor 512, the monitoring end of the monitoring camera 501 can still be naturally vertical downwards by gravity, thus realizing monitoring work in different positions. Two auxiliary blocks 516 are fixedly connected to the pivot of the hinge frame 515, and a limiting post 517 for limiting the two auxiliary blocks 516 is fixedly connected to the telescopic end of the electric telescopic rod 513. The two auxiliary blocks 516 and the two limit posts 517 are used to ensure that the articulated frame 515 can be adjusted within a certain range of angles, thereby improving its stability after angle adjustment and enhancing the stability of the surveillance camera 501 during operation.

[0028] Example 3: The difference from Example 1 is that; See attached document Figure 3 and Figure 4 Two balance columns 518 are fixedly connected to the base of the electric telescopic pole 513; The distance between the two balance columns 518 is equal to the thickness of the hinge frame 515. This allows the electric telescopic rod 513 to fully retract the monitoring camera 501 via the hinge frame 515. When the camera retracts to a certain position, the two balance columns 518 can limit the upper and lower positions of the hinge frame 515, ensuring that the tilted hinge frame 515 is naturally horizontal. This controls the monitoring end of the monitoring camera 501 to be horizontal. Furthermore, when the height of the monitoring camera 501 is adjusted in conjunction with the adjusting components, it enables the monitoring of fish at different depths within the annular water tank 100. The monitoring angle is automatically adjusted without the need for manual or electric adjustments.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
