When the buoyancy cylinder 8 is in a closed state, the accumulated water in the buoyancy cylinder 8 is discharged into the buoyancy box 5 through the pipe and discharged through the buoyancy box 5. The water pump 7 discharges the accumulated water, thereby reducing the weight of the buoyancy tube 8 and the buoyancy box 5, making it easier for the buoyancy box 5 and the buoyancy tube 8 to float on the water surface, wherein the output port of the water pump 7 is fixedly connected to a delivery pipe, the upper end of the delivery pipe passes through the side wall of the buoyancy box 5 and extends to the outside of the buoyancy box 5, making it easier for the water pump 7 to deliver the water in the buoyancy box 5 to the outside of the buoyancy box 5 through the delivery pipe, and a check valve is provided in the delivery pipe to prevent the water outside the buoyancy box 5 from flowing back into the delivery pipe.

[0052] The floating object sampling tube 11 is arranged in the buoyancy tube 8. One side of the floating object sampling tube 11 is open. The side opening of the floating object sampling tube 11 cooperates with the strip-shaped inlet 9. A cover plate 12 is rotatably connected to the inner side wall of the floating object sampling tube 11. The floating object sampling tube 11 is convenient for sampling floating objects and suspended objects in the water. The floating object sampling tube 11 and the cover plate 12 are both made of stainless steel mesh, which is convenient for the water in the floating object sampling tube 11 to seep out through the holes on its side wall, thereby facilitating the filtering treatment of the water in the floating object sample.

[0053] The support frame 1 includes a cross bar 13 and a vertical bar 14 . Moving bars 15 are inserted into both ends of the cross bar 13 . The ends of the moving bars 15 are fixedly connected to fixing blocks 16 .

[0054] The upper end surface of the vertical rod 14 is fixedly connected to the lower surface of the horizontal rod 13 , and the lower end surface of the vertical rod 14 is fixedly connected to a fixing plate 17 , on which screws are fixedly connected, and the screws are used to fix the position of the fixing plate 17 .

At least two sliders 19 are fixedly connected to the side wall of the water sample collection box 2, and the sliders 19 are slidably connected in the strip chute 18. The strip chute 18 on the horizontal bar 13 and the vertical bar 14 facilitates the horizontal or vertical movement of the water sample collection box 2 on the support frame 1, and at least two notches are provided at the bottom of the horizontal bar 13, and the sliders 19 can be downwardly separated from the horizontal bar 13 through the notches, and the two strip chute 18 are interconnected through one of the notches.

[0056] The conveying mechanism includes two drive boxes 20 , and the two drive boxes 20 are fixedly connected to the ends of the cross bar 13 .

[0057] The sprocket 21 is rotatably connected to the inner wall of the driving box 20 , a chain 22 is sleeved between the two sprockets 21 , and a first servo motor 23 is fixedly connected to the end of one of the sprockets 21 , and the first servo motor 23 is fixedly connected to the side wall of the driving box 20 .

[0058] The movable plate 24 is fixedly connected to the chain 22. The lower surface of the movable plate 24 is fixedly connected with an insertion rod 25. The insertion rod 25 is inserted into the water sample collection box 2. The upper surface of the water sample collection box 2 is provided with a socket for inserting the insertion rod 25, which is convenient for inserting the insertion rod 25 into the water sample collection box 2. When the movable plate 24 moves, the water sample collection box 2 is driven to move by the cooperation between the insertion rod 25 and the socket.

[0059] The push plate 26 is arranged on the chain 22, the push plate 26 is located on both sides of the water sample collection box 2, and the push plate 26 is inserted on the outer wall of the water sample collection box 2. The first servo motor 23 drives the chain 22 to rotate forward and reversely through the sprocket 21, thereby driving the push plate 26 to move back and forth, and the water sample collection box 2 is pushed back and forth by the push plate 26, and the water sample collection box 2 is pushed upward by the buoyancy of the buoyancy box 5 in the water, so that the upper surface of the water sample collection box 2 is aligned with the moving plate 24. The lower surface of the push plate 26 abuts against it, so that the chain 22 drives the water sample collection box 2 to move horizontally through the insertion rod 25 when driving the movable plate 24 to move horizontally. The upper end surface of the push plate 26 is fixedly connected to the second connecting plate, and the end of the second connecting plate is fixedly connected to the chain 22. A strip-shaped plug hole is opened on the side wall of the water sample collection box 2, and the top of the strip-shaped plug hole is open. The side wall of the push plate 26 is inserted into the strip-shaped plug hole, which is convenient for pushing the water sample collection box 2 to move horizontally through the push plate 26.

[0060] A rotating disk 27 is rotatably connected to the bottom of the water sample collection box 2, and a sampling bottle 4 is fixedly connected to the upper surface of the rotating disk 27. There are at least two sampling bottles 4, and multiple sampling bottles 4 are distributed in a ring shape. A second drive motor 49 is fixedly connected to the top of the water sample collection box 2, and an output end of the second drive motor 49 is fixedly connected to a rotating shaft, which is fixedly connected to the rotating disk 27, and the lower end of the rotating shaft is rotatably connected to the bottom of the water sample collection box 2, so that the second drive motor 49 drives the rotating disk 27 to rotate. During the rotation of the rotating disk 27, the positions of multiple sampling bottles 4 are converted to each other, so that different sampling bottles 4 can be replaced when sampling at different water levels.

[0061] One end of the sampling pipe 3 passes through the side wall of the water sample collection box 2 and extends to the outside of the water sample collection box 2. The sampling pipe 3 is located at one end of the water sample collection box 2 and bends downward, and the lower end of the sampling pipe 3 is located directly above one of the sampling bottles 4. The diameter of the upper end of the sampling bottle 4 is larger than the diameter of the lower end of the sampling pipe 3, which facilitates water to flow into the sampling bottle 4 through the sampling pipe 3, thereby facilitating the sampling of water.

[0062] A first automatic control valve 28 is arranged in the sampling pipe 3, and the first automatic control valve 28 is connected to the first servo motor 23 through a signal, and the first automatic control valve 28 is connected to the second drive motor 49 through a signal. When it is necessary to sample water, the first automatic control valve 28 is started, and water flows into the water sample collection box 2 through the sampling pipe 3, and flows into the sampling bottle 4 through the lower port of the sampling pipe 3. After sampling, the first automatic control valve 28 is closed. At this time, the first automatic control valve 28 transmits a signal to the second drive motor 49, and the second drive motor 49 drives the rotating disk 27 to rotate, thereby driving the replacement of the position of the sampling bottle 4, so as to facilitate sampling of water again.

[0063] The bottom of the buoyancy box 5 is hemispherical, and the upper surface of the buoyancy box 5 is fixedly connected to the first connecting plate 29, and the upper surface of the buoyancy cylinder 8 is fixedly connected to the lower surface of the first connecting plate 29. The water inlet pipe 6 is located at the lower side of the buoyancy cylinder 8, and a second automatic control valve 30 is arranged in the water inlet pipe 6. When the buoyancy box 5 is moving, since the bottom of the buoyancy box 5 is hemispherical, it can reduce the water resistance of the buoyancy box 5 during movement, thereby facilitating the water sample collection box 2 to drive the buoyancy box 5 to move horizontally, and the buoyancy cylinder 8 further improves the buoyancy effect of the buoyancy box 5. At the same time, when the buoyancy box 5 is installed in the river water, the river water will generate waves during the circulation process, or when it is installed in the lake, the wind will cause waves on the lake surface. Therefore, by arranging the buoyancy cylinders 8 on both sides of the buoyancy box 5, the parallelism of the buoyancy box 5 can be improved, and the amplitude of the buoyancy box 5 shaking in the waves can be reduced.

[0064] The two ends of the buoyancy cylinder 8 are in a closed state, and a circular plate 31 is rotatably connected to an inner side wall of the buoyancy cylinder 8, the end of the inner cylinder 10 is fixedly connected to the circular plate 31, and a strip notch 32 is clamped on the side wall of the inner cylinder 10, and the strip notch 32 cooperates with the strip inlet 9, and at least two first drainage holes 33 are opened on the circumferential wall of the buoyancy cylinder 8, and at least two second drainage holes 34 are opened on the circumferential wall of the inner cylinder 10, and the second drainage holes 34 cooperate with the first drainage holes 33. When the inner cylinder 10 rotates, and the strip notch 32 is engaged with the strip inlet 9, When overlapping, the buoyancy cylinder 8 is in an open state. At this time, water flows into the buoyancy cylinder 8 through the strip inlet 9. Since the open end of the floating object sampling cylinder 11 is opposite to the strip inlet 9, when water drives the floating objects to flow into the buoyancy cylinder 8, the floating object sampling cylinder 11 intercepts the floating objects in the water, thereby achieving the purpose of sampling the floating objects in the water. When the strip notch 32 overlaps with the strip inlet 9, the first drainage hole 33 and the second drainage hole 34 are also in an overlapping state, so that the water in the buoyancy cylinder 8 can flow out through the first drainage hole 33 and the second drainage hole 34 after overlapping.

[0065] A driving rod 35 is rotatably connected inside the buoyancy box 5 . Both ends of the driving rod 35 pass through the side walls of the buoyancy box 5 and are fixedly connected to the circular plate 31 . The driving rod 35 is used to control the rotation of the circular plate 31 , thereby facilitating the control of the rotation of the inner cylinder 10 .

[0066] A rotating cylinder 36 is sleeved on the driving rod 35, and a connecting block 37 is fixedly connected to the circumferential wall of the rotating cylinder 36. One end of the connecting block 37 is fixedly connected to the outer ring wall of the floating object sampling cylinder 11, and the end of the rotating cylinder 36 passes through the side wall of the buoyancy cylinder 8 and is rotatably connected to the buoyancy box 5.

[0067] The two ends of the floating object sampling tube 11 are closed, and a rotating plate 48 is rotatably connected to the side wall of the floating object sampling tube 11, the end of the cover plate 12 is fixedly connected to the rotating plate 48, and a rotating shaft 38 is fixedly connected to the rotating plate 48. One end of the rotating shaft 38 passes through the side wall of the floating object sampling tube 11 and is fixedly connected to the first gear 39. A connecting ring 40 is fixedly connected to one side wall of the buoyancy tube 8, and a meshing tooth 41 is arranged on the inner side wall of the connecting ring 40. The meshing tooth 41 meshes with the first gear 39. A plurality of meshing teeth 41 are distributed in an arc shape on the inner wall of the circular ring and close to the strip-shaped inlet 9, and the arc angle formed by the meshing teeth 41 is 180°. When the rotating tube 36 drives the plurality of floating object sampling tubes 11 to rotate, when the floating object sampling tube 11 rotates to the rotating tube 36 When the floating object sampling barrel 11 is directly below the rotating barrel 36, the first gear 39 on the floating object sampling barrel 11 is meshed with the meshing teeth 41. When the rotating barrel 36 drives the floating object sampling barrel 11 to rotate toward the strip-shaped inlet 9, the first gear 39 rolls on the meshing teeth 41 and drives the rotation of the cover plate 12. When the floating object sampling barrel 11 rotates to one side of the strip-shaped inlet 9, the side opening of the floating object sampling barrel 11 is opposite to the strip-shaped inlet 9, thereby facilitating the sampling of floating objects in the water. When the floating object sampling barrel 11 rotates upward, the first gear 39 rolls on the meshing teeth 41 again and drives the cover plate 12 to rotate. When the floating object sampling barrel 11 rotates to directly above the rotating barrel 36, the cover plate 12 completely covers the side opening of the floating object sampling barrel 11, and the sampling of floating objects in the water is calmly completed.

[0068] A control box 42 is fixedly connected to the top of the buoyancy box 5, and a second servo motor 43 is fixedly connected to the bottom of the control box 42. A second gear 44 is fixedly connected to the output shaft of the second servo motor 43 and the drive rod 35, and the two second gears 44 are meshed with each other. A through hole for the rotating cylinder 36 to pass through is opened on the side walls of the buoyancy box 5 and the control box 42, and a sealing gasket is fixedly connected to the circumferential wall of the through hole. The inner annular wall of the sealing gasket contacts the outer annular wall of the rotating cylinder 36, so as to increase the sealing between the outer annular wall of the rotating cylinder 36 and the through hole, and prevent water from penetrating into the control box 42 through the gap between the rotating cylinder 36 and the through hole.

[0069] A first drive motor 45 is fixedly connected to the side wall of the control box 42, a rotating rod 46 is fixedly connected to the output shaft of the first drive motor 45, a third gear 47 is fixedly connected to the rotating rod 46 and the rotating cylinder 36, and the third gear 47 on the rotating rod 46 is meshed with the third gear 47 on the rotating cylinder 36.

[0070] Working principle: The fixed blocks 16 are fixed on both sides of the river channel by existing technical means such as screws, and then the fixed plates 17 are fixed on the riverbed by screws. When the width of the two sides of the river channel is greater than the width of the cross bar 13, the two fixed blocks 16 are pulled to both sides, and the moving rod 15 slides to the outside of the cross bar 13, thereby increasing the distance between the two fixed blocks 16 and the vertical rod 14, thereby facilitating the installation of the support frame 1 on rivers of different widths and improving the utilization rate of the support frame 1.

[0071] Since the interior of the buoyancy box 5 and the buoyancy cylinder 8 are hollow, and both the buoyancy box 5 and the buoyancy cylinder 8 have buoyancy, the buoyancy box 5 drives the water sample collection box 2 to float on the water surface through the buoyancy of the buoyancy box 5 and the buoyancy cylinder 8 on the water, and the port of the sampling pipe 3 located on the outside of the water sample collection box 2 is located in the water. When sampling is required, the first automatic control valve 28 is started. At this time, water flows into the water sample collection box 2 through the sampling pipe 3, and flows into the sampling bottle 4 through the lower port of the sampling pipe 3, and the opening time of the first automatic control valve 28 is set. When the sampling is completed, the first automatic control valve 28 is closed, and the first automatic control valve 28 transmits a signal to the second drive motor 49. The second drive motor 49 drives the rotating disk 27 to rotate, so that the sampling bottle 4 loaded with the sample rotates to one side, and the sampling bottle 4 not loaded with the sample rotates to the bottom of the lower port of the sampling pipe 3, so as to facilitate the second sampling of water.

[0072] When the sampling position needs to be changed, the first servo motor 23 is started, and the output shaft of the first servo motor 23 drives the chain 22 to rotate through the sprocket 21, thereby driving the movable plate 24 and the push plate 26 to move horizontally. During the horizontal movement of the movable plate 24 and the push plate 26, the water sample collection box 2 is pushed to move horizontally. When the water sample collection box 2 moves to one side of the vertical rod 14, and the slider 19 located in the middle part of the water sample collection box 2 is located directly above the strip slide 18 on the vertical rod 14, and the position of the slider 19 corresponds to the position of the notch at the bottom of the cross bar 13, the second automatic control valve 30 is opened to allow water to flow into the buoyancy box 5 through the water inlet pipe 6. The buoyancy box 5 is thus filled with water, thereby increasing the weight of the buoyancy box 5. As the water in the buoyancy box 5 increases, the gravity of the buoyancy box 5 will also increase, causing the buoyancy box 5 to drive the water sample collection box 2 to sink, so that the water sample collection box 2 sinks into the water. When the water sample collection box 2 sinks to the middle section of the vertical rod 14 and it is necessary to sample the water, the second automatic control valve 30 is closed to stop the external water from continuing to flow into the buoyancy box 5 through the water inlet pipe 6, thereby preventing the buoyancy box 5 from continuing to sink, and then the first automatic control valve 28 is opened to allow the water to flow into the sampling bottle 4 through the sampling pipe 3, thereby realizing the sampling of water at different depths.

[0073] When the buoyancy box 5 sinks to the middle section of the vertical rod 14 and it is necessary to sample the suspended matter in the water, the second servo motor 43 is turned on, and the output shaft of the second servo motor 43 drives the driving rod 35 to rotate through the mutually meshing second gear 44, and drives the circular plate 31 and the inner cylinder 10 to rotate through the driving rod 35. When the strip notch 32 on the inner cylinder 10 overlaps with the strip inlet 9, the first drainage hole 33 and the second drainage hole 34 are also in an overlapping state, and the buoyancy cylinder 8 is in an open state. Water flows into the buoyancy cylinder 8 through the strip inlet 9 and the strip notch 32, and then the first driving motor 45 is started, and the output shaft of the first driving motor 45 drives the rotating rod 46 to rotate, and drives the rotating cylinder 36 to rotate through the mutually meshing third gear 47, thereby driving the floating object sampling cylinder 11 to rotate through the rotating cylinder 36. When the floating object sampling cylinder 11 When it rotates to the bottom of the rotating cylinder 36, the first gear 39 on the floating object sampling cylinder 11 meshes with the meshing teeth 41. When the rotating cylinder 36 drives the floating object sampling cylinder 11 to rotate toward the strip-shaped inlet 9, the first gear 39 rolls on the meshing teeth 41 and drives the cover plate 12 to rotate. When the floating object sampling cylinder 11 rotates to one side of the strip-shaped inlet 9, the side opening of the floating object sampling cylinder 11 is opposite to the strip-shaped inlet 9. When water flows into the buoyancy cylinder 8 through the strip-shaped inlet 9, since the open end of the floating object sampling cylinder 11 is opposite to the strip-shaped inlet 9, when the water drives the floating object to flow into the buoyancy cylinder 8, the floating object sampling cylinder 11 intercepts the floating objects in the water, thereby achieving the purpose of sampling the floating objects in the water. At the same time, since the first drainage hole 33 and the second drainage hole 34 on the buoyancy cylinder 8 and the inner cylinder body 10 overlap, as shown in FIG. Figure 8 As shown, the water in the buoyancy cylinder 8 is facilitated to flow out through the overlapped first drainage hole 33 and the second drainage hole 34, thereby reducing the flow resistance of the buoyancy cylinder 8 to the river water. After sampling of the floating objects in the water at the water level where the buoyancy cylinder 8 is located is completed, the first drive motor 45 is started again, the first drive motor 45 drives the rotating cylinder 36 to rotate, and drives the floating object sampling cylinder 11 loaded with floating objects to rotate upward, the first gear 39 rolls on the meshing teeth 41 again and drives the cover plate 12 to rotate, when the floating object sampling cylinder 11 rotates to the top of the rotating cylinder 36, the cover plate 12 completely covers the side opening of the floating object sampling cylinder 11, and the sampling of floating objects in the water is calmly completed.

[0074] When it is necessary to sample the suspended matter in the water at the bottom of the vertical rod 14, that is, to sample the suspended matter in the water at the bottom of the river channel, the second servo motor 43 is turned on, and the second servo motor 43 drives the driving rod 35 to rotate in the opposite direction through the second gear 44, thereby driving the inner cylinder 10 to rotate in the opposite direction. When the strip notch 32 and the strip inlet 9 are in relative positions, the outer annular wall of the inner cylinder 10 covers the port of the strip inlet 9, thereby closing the strip inlet 9, and the positions of the first drainage hole 33 and the second drainage hole 34 are staggered, as shown in FIG. Fig.10, so that the river water cannot flow into the buoyancy cylinder 8, and the second automatic control valve 30 is opened again, so that the river water continues to flow into the buoyancy box 5 through the water inlet pipe 6, and the gravity value of the buoyancy box 5 is continuously increased by the injection of river water, so that the buoyancy box 5 drives the water sample collection box 2 to continue to sink to the bottom of the river channel. When the buoyancy box 5 contacts the bottom of the river channel, the second servo motor 43 is turned on, and the second servo motor 43 drives the inner cylinder 10 to rotate, so that the position of the strip notch 32 overlaps with the position of the strip inlet 9, so as to facilitate the sampling of suspended matter in the water at the bottom of the river channel, thereby realizing the sampling of floating objects with different height values ​​in the water, which brings convenience to the staff.

[0075] After the sampling of the water sample and the suspended matter at the bottom of the river channel is completed, the second servo motor 43 is started, and the inner cylinder 10 is driven by the second servo motor 43 to rotate in the opposite direction, so that the outer ring wall of the inner cylinder 10 covers the strip inlet 9, and the strip notch 32 is opposite to the inner ring wall of the buoyancy cylinder 8, as shown in FIG. Fig.10 As shown, at this time, the buoyancy tube 8 is in a closed state, and the second automatic control valve 30 is closed, and the water pump 7 is turned on. The water pump 7 transports the water in the buoyancy box 5 to the outside of the buoyancy box 5 through the delivery pipe, thereby discharging the water in the buoyancy box 5. As the water in the buoyancy box 5 is gradually discharged, the weight of the buoyancy box 5 is gradually reduced, so that the water sample collection box 2 is pushed upward by the buoyancy of the buoyancy box 5 in the water. Due to the cooperation between the strip slide 18 and the slider 19 on the vertical rod 14, the position of the water sample collection box 2 is prevented from shifting during the upward floating process. When the water sample collection box 2 floats out of the water, the insertion rod 25 is inserted into the water sample collection box 2, so that the movable plate 24 continues to push the water sample collection box 2 to move horizontally during the movement, thereby realizing the sampling of water and suspended matter in water at different positions and depths, improving the accuracy of the hydrological and water resources survey results, and bringing convenience to the staff.
