[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2An embodiment of this utility model provides a fishery survey device for easy water sample collection, comprising a square tube 1, a rack 2 fixedly connected to the inner wall of the square tube 1, a gear 3 meshing with the tooth end of the rack 2, an anti-slip pad 4 fixedly connected to the outer wall of the gear 3, a rack 5 meshing with the tooth end of the gear 3, an inner tube 6 fixedly connected to the outer wall of the rack 5, a filter plate 7 fixedly connected to the inside of the inner tube 6, a suction nozzle 8 fixedly connected to the inner wall of the inner tube 6, a fixed bracket 9 fixedly connected to the outer wall of the inner tube 6, a water suction device 10 fixedly connected to the upper surface of the fixed bracket 9, a water pipe 11 provided inside the inner tube 6, and a limiting component provided on the outer wall of the square tube 1 to prevent the square tube 1 from falling.

[0025] Specifically, pulling down the inner tube 6 moves the rack 5, which in turn moves the gear 3. The square tube 1 restricts the inner tube 6, ensuring its position doesn't shift during movement. Simultaneously, the square tube 1 fixes the rack 2, ensuring its position doesn't change. The rack 2 meshes with the gear 3, so that the movement of the gear 3 synchronously moves the rack 5, which in turn moves the suction nozzle 8. When the suction nozzle 8 reaches a certain water depth, the water suction device 10 is activated, and the water is filtered through the filter plate 7. The inner tube 6 fixes the suction nozzle 8, ensuring its position doesn't change during movement, and also fixes the filter plate 7. To ensure that the filter plate 7 will not fall off during filtration, and the anti-slip pad 4 restricts the gear 3, preventing it from falling off during movement, the water absorber 10 is fixed by the fixed bracket 9, ensuring that the position of the water absorber 10 will not shift during operation. After filtration by the filter plate 7, the water passes through the inner tube 6 and then flows into the water pipe 11. The inner tube 6 fixes the water pipe 11, ensuring that its position will not shift during transportation, and the water pipe 11 guides the sampling tube 23, allowing the water sample inside the water pipe 11 to flow into the sampling tube 23, thus completing the water sample collection. This not only achieves the effect of controlling the extension depth and adapting to sampling at different water depths, but also achieves the effect of water sample purity and improved sampling efficiency.

[0026] Reference Figure 1 The limiting component includes an I-frame 12, the inner wall of which is set on the outer wall of the square tube 1, and a fixed bracket 13 is fixedly connected to the outer wall of the I-frame 12. A limiting frame 14 is fixedly connected to the outer wall of the fixed bracket 13.

[0027] Specifically, the I-beam frame 12 restricts the square tube 1 so that the position of the square tube 1 does not change. The I-beam frame 12 is fixed by the second fixed bracket 13 so that the position of the I-beam frame 12 does not change. The second fixed bracket 13 is also used to fix the limiting frame 14 so that the position of the limiting frame 14 does not change and it supports the inner tube 6.

[0028] Reference Figure 1 , Figure 3 and Figure 4 A universal wheel 15 is fixedly connected to the lower surface of the fixed bracket 13, a motor 16 is fixedly connected to the lower surface of the limiting bracket 14, a limiting post 17 is fixedly set at the output end of the motor 16, a rotating rod 18 is fixedly connected to the outer wall of the limiting post 17, a limiting post 29 is fixedly connected to the outer wall of the rotating rod 18, a rotating rod 20 is rotatably connected to the outer wall of the limiting post 29, a limiting post 3 21 is fixedly connected to the outer wall of the rotating rod 20, a clamp 22 is fixedly connected to the upper surface of the limiting post 3 21, and a sampling tube 23 is attached to the inner wall of the clamp 22.

[0029] Specifically, the caster wheel 15 is fixed by the limiting bracket 14, so that when the caster wheel 15 moves, it synchronously drives the fixed bracket 13 to move. The starting motor 16 drives the limiting post 17 to rotate, which in turn drives the rotating rod 18 to rotate. During operation, the fixed bracket 13 fixes the motor 16 to ensure that the position of the motor 16 does not change during operation. At the same time, the fixed bracket 13 restricts the limiting post 17 to ensure that the position of the limiting post 17 does not shift when driven to rotate by the motor 16. The limiting post 17 also restricts the rotating rod 18, so that when the limiting post 17 rotates, it synchronously drives the rotating rod 18 to rotate. This rotation of the rotating rod 18 drives the limiting post 19 to rotate. The rotating rod 20 rotates, which in turn rotates the limiting post 21. The rotating rod 18 restricts the limiting post 29, so that the rotation of the rotating rod 18 synchronously drives the limiting post 29 to rotate. At the same time, the limiting post 29 restricts the rotating rod 20, ensuring that the rotation of the limiting post 29 synchronously drives the rotating rod 20 to rotate. The rotating rod 20 fixes the limiting post 21, so that the position of the limiting post 21 does not change. Thus, the rotation of the limiting post 21 drives the clamp 22 to move. The clamp 22 moves to clamp and fix the sampling tube 23, so that the position of the fixing bracket 23 does not change when the water sample is input into the water tube 11, achieving the effect of clamping and fixing to prevent leakage when the water sample is input.

[0030] Reference Figure 1 , Figure 3 and Figure 4The sampling tube 23 is slidably connected to an inner tube 24, and a handle 25 is fixedly connected to the outer wall of the inner tube 24. A sealing plug 26 is fixedly connected to the upper surface of the sampling tube 23. A sample tube groove 27 is opened on the upper surface of the fixed bracket 13. A limiting plate 28 is attached to the outer wall of the fixed bracket 13, and a handle 29 is fixedly connected to the outer wall of the limiting plate 28.

[0031] Specifically, when a large volume of water sample is required, pulling handle 25 outward moves the inner tube 24, thus increasing the internal space of the sampling tube 23. The sampling tube 23 restricts and guides the inner tube 24, ensuring that its position does not shift when pulled outward. Simultaneously, the inner tube 24 fixes handle 25, ensuring that pulling handle 25 moves the inner tube 24 synchronously. The sampling tube 23 also fixes the sealing plug 26, sealing the water sample inside the sampling tube 23. Once the water sample is fully injected into the sampling tube 23, pulling handle 29 outward moves the limiting plate 28. The limiting plate 28 fixes handle 29, ensuring that pulling handle 29 moves the limiting plate 28 synchronously. The fully filled sampling tube 23 is then placed into the sample tube slot 27 for water sample collection and storage.

[0032] Reference Figure 1 and Figure 2 The outer wall of the inner tube 6 is slidably connected to the inside of the square tube 1, and the outer wall of the anti-slip pad 4 is slidably connected to the inside of the square tube 1.

[0033] Specifically, the square tube 1 restricts the inner tube 6 so that its position does not change when it slides, and the anti-slip pad 4 restricts the square tube 1 so that the gear 3 does not fall off when it moves.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The outer wall of the limiting post 17 is rotatably connected to the inside of the fixed bracket 2 13, the lower surface of the clamp 22 is slidably connected to the upper surface of the fixed bracket 2 13, and the outer wall of the water pipe 11 is fixedly connected to the inner wall of the sampling pipe 23.

[0035] Specifically, the limiting post 17 is restricted by the fixed bracket 2 13 so that the position of the limiting post 17 will not shift when it is driven to rotate by the motor 16. The clamp 22 is guided by the fixed bracket 2 13 so that the clamp 22 will not fall off when it moves. The sampling tube 23 is guided by the water pipe 11 so that the water sample inside the water pipe 11 flows into the sampling tube 23.

[0036] Reference Figure 1 , Figure 3 and Figure 4The lower surface of the sampling tube 23 is in contact with the upper surface of the fixed bracket 2 13, and the outer wall of the limiting post 3 21 is slidably connected to the inner wall of the fixed bracket 2 13.

[0037] Specifically, the sampling tube 23 is supported by the fixed bracket 2 13 so that the position of the sampling tube 23 does not change. The fixed bracket 2 13 restricts and guides the limiting post 3 21 so that the limiting post 3 21 can only slide inside the fixed bracket 2 13.

[0038] Reference Figure 1 , Figure 3 and Figure 4 The lower surface of the limiting post 19 is rotatably connected to the upper surface of the fixed bracket 13, and the lower surface of the rotating rod 18 is rotatably connected to the upper surface of the fixed bracket 13.

[0039] Specifically, the second fixed bracket 13 supports the second limiting post 19 so that the position of the second limiting post 19 will not fall when it rotates. The second fixed bracket 13 restricts the first rotating rod 18 so that the position of the first rotating rod 18 will not change when it moves.

[0040] Working principle: When water samples need to be collected during fishery surveys, the inner tube 6 is pulled down, which moves the fixed rack 5. The rack 5 moves synchronously, which drives the gear 3 to rotate. This causes the suction nozzle 8 to move with the gear 3 to adjust the depth. After the suction nozzle 8 reaches the specified water depth, the water suction device 10 supported by the fixed bracket 9 is activated. The water passes through the filter plate 7 to filter impurities, and then is guided through the inner tube 6 to the water pipe 11. Finally, the water pipe 11 guides the water into the sampling tube 23, completing the water sample collection. This not only achieves the effect of controlling the extension and retraction depth and adapting to different water depths, but also achieves the effect of water sample purity and improved sampling efficiency.

[0041] When the universal wheel 15 drives the equipment to fix the sampling tube 23 and inject water sample, the motor 16 supported by the fixed bracket 2 13 is started to drive the limiting column 17 to rotate, and the rotating rod 18 rotates synchronously, which in turn drives the limiting column 2 19, the rotating rod 20, and the limiting column 3 21 to rotate in linkage. Finally, the limiting column 3 21 drives the clamp 22 to move, so that the clamp 22 moves to clamp and fix the sampling tube 23, achieving the effect of clamping and fixing to prevent water sample from leaking during input.

[0042] When a large volume of water sample needs to be collected, pull the handle 25 fixed to the inner tube 24. The inner tube 24 slides outward inside the sampling tube 23, expanding the internal space of the sampling tube 23. The sealing plug 26 prevents leakage or contact with air during water sample storage. After the sampling tube 23 is filled with water sample, pull the handle 29 and then place the water sample-filled sampling tube 23 into the sample tube slot 27 for centralized storage. This achieves the effects of water sample storage being airtight, orderly storage, and preventing water sample leakage.

[0043] This fishery survey equipment not only achieves the effects of controlling the extension and retraction depth, adapting to different water depths for sampling, and ensuring water sample purity and improving sampling efficiency, but also achieves the effects of clamping and fixing to prevent water sample leakage during input, and achieves the effects of water sample storage sealing, orderly storage, and water sample avoidance.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
