[0047] The mounting seat 324 is used to connect the roller 323 to the sliding block 321, and the elastic force generated by the elastic portion 325 can push the roller 323 to always move against the inner wall of the guide groove, effectively ensuring the stability of the sliding block 321 along the annular track 210.

[0048] Furthermore, the elastic portion 325 here is a spring, a spring sheet and an elastic block that are common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0050] By arranging underwater thrusters 322 with opposite propulsion directions on both sides of the sliding block 321 , the sliding block 321 can be driven to slide in opposite directions relative to the annular track 210 .

[0051] Furthermore, the underwater propeller 322 in the present device is a common and easily purchased device on the market, and is a conventional configuration well known to those skilled in the art, and will not be described in detail.

[0052] In this embodiment, Figure 1 As shown, the device also includes a stirring component 400, which includes a stirring paddle 410 and a drive motor 420. The stirring paddle 410 is built into the cultivation tank 100 and can rotate relative to the cultivation tank 100. The fixed end of the drive motor 420 is connected to the bottom of the cultivation tank 100, and the output shaft is connected to the stirring paddle, which is used to drive the stirring paddle to rotate around the axis of the output shaft of the drive motor 420.

[0053] By setting a stirring paddle 410 in the breeding pond 100, the stirring paddle 410 is driven by the output shaft of the driving motor 420 to rotate relative to the breeding pond 100. The rotating stirring paddle 410 can stir the water and create an upstream environment, which is used to detect and observe the upstream swimming ability and endurance of the fry.

[0054] Furthermore, in order to prevent the stirring paddle 410 from causing damage to the fish fry, the stirring paddle 410 rotates at a low speed in the cultivation tank 100, which is a conventional setting known to those skilled in the art and will not be described in detail.

[0055] As an implementation method, Figure 1 As shown, the stirring assembly 400 further includes a mesh cover 430 , which covers the stirring paddle 410 and is connected to the bottom inner wall of the cultivation tank 100 .

[0056] The mesh cover 430 is provided on the stirring paddle to separate the stirring paddle 410 from the fish fry, so as to prevent the rotation of the stirring paddle from damaging the fish fry.

[0057] The specific working process of the present invention is that a circular track 210 and a driving member 220 are provided in the breeding pond 100. The movable end of the driving member 220 is extended or shortened relative to its fixed end, and can drive the circular track 210 to rise and fall relative to the bottom inner wall of the breeding pond 100.

The image detection unit 310 can slide along the guide of the circular track 210 along with the sliding member 320 and collect underwater image information in the breeding pond 100. Compared with the existing technology, underwater image information is collected by providing an image detection unit 310 in the breeding pond 100, wherein the image detection unit 310 can slide along the guide of the circular track 210, and the image detection unit 310 can also rise and fall relative to the bottom inner wall of the breeding pond 100 along with the circular track 210, thereby increasing the freedom of movement of the image detection unit 310, so that it can collect images from multiple angles underwater and accurately detect the fish conditions in the breeding pond 100.

[0058] During use, if the user needs to monitor and observe the fish fry in the breeding pond 100, first drive the underwater propeller 322 to generate thrust, push the sliding block 321 and the image detection unit 310 to slide along the guide of the circular track 210, and collect image information in the breeding pond 100. Then, the extended end of the linear drive part 223 can be driven to extend or shorten relative to its fixed end to drive the circular track 210, the sliding block 321 and the image detection unit 310 to rise and fall as a whole, and monitor and observe the fish fry in different water depths. Finally, the user drives the stirring paddle to rotate through the output shaft of the drive motor 420, stirs the water body to create an upstream environment, and detects and observes the upstream swimming ability and endurance of the fish fry.

[0059] The device, through the above structure, can solve the technical problem in the prior art that the detection effect cannot be achieved because the fry must be observed and detected after entering the observation tube.

[0060] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
