One end of the upper side of the top plate 9 is rotatably connected with a rotating shaft 10. The top end of the rotating shaft 10 is fixedly connected with a connecting rod 11. The connecting rod 11 is of an L-shaped structure. The upper end of the bottom plate 1 is fixedly connected with a box body 21. Two water pools 22 are fixedly connected vertically inside the box body 21. Sampling assemblies 16 are arranged at the end of the connecting rod 11 and inside the water pools 22. The sampling assembly 16 includes a connecting frame 18. The bottom of the connecting frame 18 is fixedly connected with a fixing rod 17. The bottom of the fixing rod 17 is fixedly connected with a sampling bucket 20.

[0029] As Figures 1-7As shown in the figure, on one side of the sleeve rod 2, fixing plates 6 are symmetrically and fixedly connected to both ends of the slotted groove 4. A screw rod 7 is rotatably connected between the fixing plates 6. One end of the screw rod 7 is threadedly connected to the fixing block 5. On the upper side of the fixing plate 6 at the top, a first motor 8 is fixedly connected. The output end of the first motor 8 penetrates through the corresponding fixing plate 6 and is fixedly connected to one end of the screw rod 7. Starting the first motor 8 drives the screw rod 7 to rotate, thereby driving the fixing block 5 to slide up and down along the slotted groove 4, further driving one end of the insertion rod 3 to move up and down inside the sleeve rod 2, and then driving the connecting rod 11 at the top of the insertion rod 3 and its sampling assembly 16 to move up and down, facilitating adjusting the height of the sampling assembly 16 at the end of the connecting rod 11 as needed, inserting it into the pond for sampling or removing it from the pond.

[0030] As Figures 1-7 shown in the figure, on one side of the rotating shaft 10 at the upper end of the top plate 9, a connecting shaft 13 is rotatably connected. At the top of the connecting shaft 13, a driving gear 14 is fixedly connected. One end of the rotating shaft 10 is fixedly connected with a driven gear 12. The driven gear 12 meshes with the driving gear 14. At the bottom of the top plate 9, at the position corresponding to the connecting shaft 13, a second motor 15 is fixedly connected. The output end of the second motor 15 penetrates through the top plate 9 and is fixedly connected to one end of the connecting shaft 13. Starting the second motor 15 drives the connecting shaft 13 and the driving gear 14 to rotate, thereby driving the driven gear 12 meshing with the driving gear 14 to rotate, and then driving the rotating shaft 10 to rotate, which can realize the horizontal rotation of the connecting rod 11 and its sampling assembly 16 around the axis of the rotating shaft 10, facilitating changing the sampling position. At the same time, it is also convenient to rotate the connecting rod 11 above the land, and the staff can replace the sampling assembly 16, remove the sampling assembly 16 that has completed sampling and place it in the water tank 22 for temporary storage.

[0031] As Figures 1-7 shown in the figure, inside the box body 21, above the corresponding water tank 22, a number of U-shaped frames 23 are fixedly connected. The connecting frames 18 corresponding to the sampling assembly 16 are hung on the upper ends of the U-shaped frames 23 to prevent the sampling bucket 20 from tipping over during the movement, causing the fry to overflow. Both sides of the end of the connecting rod 11 and both ends of the corresponding connecting frame 18 are detachably connected by connecting bolts 19, which is convenient for loading and unloading. The sampled sampling assembly 16 is unloaded and placed in the water tank 22 for storage, and then the empty sampling assembly 16 is reinstalled on the connecting rod 11 for the next sampling.

The control panel 25 is electrically connected to both the first motor 8 and the second motor 15, facilitating the control of the switches of the first motor 8 and the second motor 15. An oxygenation pump is provided in each of the pools 22 to provide sufficient oxygen for the fry temporarily stored in the pools 22, preventing the fry from dying due to lack of oxygen and affecting the sampling result statistics. A power supply assembly 26 is provided at the upper end of the bottom plate 1. The power supply assembly 26 is a battery pack. The power supply assembly 26 is electrically connected to the first motor 8, the second motor 15, the control panel 25, and the oxygenation pump to provide a power source for them.

[0033] As Figures 1-7 shown in the figure, a push handle frame 24 is fixedly connected to one end of the bottom plate 1. Universal wheels 27 are fixedly connected to the four corners of the bottom of the bottom plate 1, facilitating movement and taking fry samples at different positions in the pond.

[0034] Working principle: When in use, start the first motor 8, which drives the screw rod 7 to rotate, thereby driving the fixed block 5 to slide up and down along the slot 4, and then driving one end of the insertion rod 3 to move up and down inside the sleeve rod 2, and further driving the connecting rod 11 at the top of the insertion rod 3 and its sampling assembly 16 to move up and down, facilitating the adjustment of the height of the sampling assembly 16 at the end of the connecting rod 11 as needed, inserting it into the pond for sampling or removing it from the pond water surface. Start the second motor 15, which drives the connecting shaft 13 and the driving gear 14 to rotate, and then drives the driven gear 12 meshing with the driving gear 14 to rotate, and further drives the rotating shaft 10 to rotate, enabling the horizontal rotation of the connecting rod 11 and its sampling assembly 16 around the axis of the rotating shaft 10, facilitating the change of the sampling position, and also facilitating the rotation of the connecting rod 11 above the land. The staff can replace the sampling assembly 16, remove the sampling assembly 16 that has completed sampling and place it in the pool 22 for temporary storage. In this way, the sampled fry at different positions can be stored separately and are not easily confused, making it convenient and fast for later statistical detection.
