Manually drive the first drive motor to move upward relative to the motor mounting shell body, so that the second limit plate is separated from the second limit groove, and the second limit is completed. The drive motor and the motor mounting shell body are separated. When the first drive motor needs to be installed, the first drive motor is manually driven to move so that the second limit plate is inserted into the second limit groove.

[0018] (4) The second gear is driven to rotate by the second driving motor, and the second gear and the second gear ring cooperate to make the second gear drive the second gear ring and the rotating ring to rotate relative to the second fixed ring, and the infrared rangefinder body is driven to move by the second connecting plate, thereby changing the position of the infrared rangefinder body to measure the thickness of the sediment at different positions on the sediment accumulation measuring seat;

[0019] (5) Sediment enters the sediment collecting tube body through the funnel. Sediment can be collected and sampled through the sediment collecting tube body and the funnel.

[0039] The second gear 46 is driven to rotate by the second drive motor 45, and then the second gear 46 cooperates with the second gear ring 43, so that the second gear 46 drives the second gear ring 43 and the rotating ring 40 to rotate relative to the second fixed ring 39, and then the infrared rangefinder body 4 is driven to move by the second connecting plate 42. By changing the position of the infrared rangefinder body 4, the thickness of the sediment at different positions on the sediment accumulation measuring seat 1 can be measured, and the sediment enters the sediment collecting cylinder body 2 through the funnel 3. The sediment can be collected and sampled through the sediment collecting cylinder body 2 and the funnel 3. The bolt 48 is manually driven to rotate so that the bolt 48 is disengaged from the mounting ring 47 and the sediment accumulation measuring seat 1, and the sediment collecting cylinder body 2 can be dismantled, making it easy to remove the sediment collecting cylinder body 2 with collected sediment.

[0040] Example 5, based on Example 1, Figure 6 and Figure 9 The elastic pushing mechanism includes a fixed block 49 fixedly mounted on the rotating and stabilizing plate 8, a slide groove 50 is provided on the fixed block 49, two clamping sliders 51 are provided in the slide groove 50, and two adjacent clamping sliders 51 are connected by a second compression spring 52. A plurality of guide grooves 53 are provided on the inner wall of the slide groove 50, and a guide block 54 is fixedly connected to the clamping slider 51, and the guide block 54 is located in the guide groove 53. The two adjacent clamping sliders 51 are respectively in contact with the two flip support side plates 9;

[0041] The flip support side plate 9 is no longer in contact with the inner wall of the placement groove 7. When the flip support side plate 9 can rotate relative to the rotating stabilizing plate 8, the second compression spring 52 is in a compressed state, and then the second compression spring 52 drives the two clamping sliders 51 to move away from each other. The design of the guide groove 53 and the guide block 54 prevents the clamping slider 51 from disengaging from the slide groove 50. When the clamping slider 51 moves, the flip support side plate 9 is driven by the clamping slider 51 to rotate relative to the rotating stabilizing plate 8. The flip support side plate 9 is supported by the baffle 15. The clamping slider 51 and the baffle 15 clamp the two sides of the flip support side plate 9 so that the flip support side plate 9 and the rotating stabilizing plate 8 are in the same horizontal plane.

[0042] Working principle: During operation, the support leg 5 is inserted into the designated position, and through the design of the transmission lifting assembly, the movable support seat 13 is driven to move in the vertical direction. By driving the movable support seat 13 downward, the iron block 12 drives the magnet 11 and the first connecting plate 10 to change its inclination angle. The magnet 11 is no longer magnetically attracted to the iron block 12, and the rotating stabilizing plate 8 rotates so that the rotating stabilizing plate 8 is perpendicular to the support leg 5. One side of the first connecting plate 10 contacts the side wall of the movable support seat 13. The position of the first connecting plate 10 and the rotating stabilizing plate 8 is limited by the movable support seat 13 to prevent the rotating stabilizing plate 8 and the first connecting plate 10 from shaking. At the same time, the flip support side plate 9 no longer contacts the inner wall of the placement slot 7, and the flip support side plate 9 can rotate relatively. The stabilizing plate 8 rotates, and the second compression spring 52 is in a compressed state, and then the second compression spring 52 drives the two clamping slide blocks 51 to move away from each other. The design of the guide groove 53 and the guide block 54 prevents the clamping slide block 51 from disengaging from the slide groove 50. When the clamping slide block 51 moves, the clamping slide block 51 drives the flipping support side plate 9 to rotate relative to the rotating stabilizing plate 8, and the flipping support side plate 9 is supported by the baffle 15. The clamping slide block 51 and the baffle 15 clamp the two sides of the flipping support side plate 9 so that the flipping support side plate 9 and the rotating stabilizing plate 8 are in the same horizontal plane, which increases the resistance of the sediment accumulation measuring seat 1 and the support leg 5 to move upward, thereby increasing the stability of the sediment accumulation measuring seat 1 and reducing the tipping of the sediment accumulation measuring seat 1 during the measurement process. The possibility of improving measurement accuracy is improved. The first limit plate 28 and the first fixed plate 26 are driven to rotate by the first driving motor 29, and then the rotating shaft 24 drives the turntable 20 to rotate, so that the connecting rod 22 drives the first gear ring 21 to rotate. Through the cooperation of the first gear ring 21 and the first gear 23, when the first gear ring 21 rotates, several first gears 23 can be rotated synchronously, thereby rotating the screw rod 17, changing the length of the screw rod 17 in the threaded sleeve 16, thereby adjusting the height of the threaded sleeve 16 and the movable support seat 13, and manually driving the movable plate 35 to move away from the motor mounting shell body 30, so that the insert block 34 disengages from the first fixed ring 33, and the fixed column 36 and the second fixed plate 37 move synchronously, and the first compression spring 38 is in compression. When the first drive motor 29 needs to be installed, the first drive motor 29 is manually driven to move so that the second limiting plate 31 is inserted into the second limiting groove 32.The motor mounting housing body 30 is manually driven to move upward relative to the sediment accumulation measuring seat 1, so that the first limit plate 28 is inserted into the first limit groove 27, and the first fixing ring 33 is inserted into the motor mounting housing body 30. The movable plate 35 is manually loosened, and the first compression spring 38 drives the second fixing plate 37 to move, thereby moving the fixing column 36 and the movable plate 35, so that one end of the insert block 34 is inserted into the first fixing ring 33, so that the motor mounting housing body 30 can be fixed relative to the sediment accumulation measuring seat 1, completing the installation of the first drive motor 29, and the second gear 46 is driven to rotate by the second drive motor 45, and then the second gear 46 and the second gear ring 43 cooperate. The second gear 46 drives the second gear ring 43 and the rotating ring 40 to rotate relative to the second fixed ring 39, thereby driving the infrared rangefinder body 4 to move via the second connecting plate 42. By changing the position of the infrared rangefinder body 4, the thickness of the sediment at different locations on the sediment accumulation measurement base 1 can be measured. The sediment enters the sediment collection tube body 2 through the funnel 3. The sediment can be collected and sampled through the sediment collection tube body 2 and the funnel 3. The bolt 48 is manually driven to rotate, so that the bolt 48 disengages the mounting ring 47 and the sediment accumulation measurement base 1, and the sediment collection tube body 2 is completely removed, making it easier to remove the sediment collection tube body 2 after collecting the sediment.
