Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example; please refer to Figure 1 - Figure 2 The illustrated seawater sampling device with a self-contained float includes a base 1 and a sampling cylinder 4. The sampling cylinder 4 is engraved with scale lines 41 for observing the capacity; the sampling capacity can be observed intuitively, making it convenient for operators to accurately control the sampling amount to meet different sampling needs; it is also convenient to monitor the sampling progress in real time during the sampling process, avoiding over- or under-sampling, and improving sampling efficiency and accuracy; the sampling cylinder 4 is inserted into the middle of the upper surface of the base 1, and a rotating drain outlet 42 is rotatably connected to the bottom of the sampling cylinder 4; a sampling element 2 for sampling seawater is provided on the right side of the upper surface of the base 1.

[0022] Sampling component 2 includes a fixed base 21 fixedly installed on the top right side of the base 1. A water pump 22 is detachably installed on the top of the fixed base 21 by bolts. A water pump 23 is inserted into the right end of the water pump 22. A winding reel 24 for winding the water pump 23 is rotatably connected to the front of the fixed base 21. This facilitates the storage and organization of the water pump 23, preventing it from scattering or tangling when not in use, reducing pipe wear, and extending its service life. After sampling, the water pump 23 can be quickly retrieved, improving operational convenience and saving manpower and time. A drain pipe 211 is inserted into the left end of the water pump 22. Two sets of first screws 25 of the same diameter are threadedly connected to the right side of the fixed base 21. An adjusting plate 26 is rotatably connected to the two sets of first screws 25. A buffer sleeve 27 for the water pump 23 to pass through is fixedly installed on the adjusting plate 26. A buffer sponge pad for protecting the water pump 23 is adhered inside the buffer sleeve 27. This can reduce the impact of water pump 23 on the water pump 22. The direct friction between the pumping pipe 23 and the buffer sleeve 27 is minimized to prevent wear of the pumping pipe 23 due to frequent contact or shaking, thus protecting the structural integrity of the pumping pipe 23. The sponge pad is elastic and can buffer the vibration of the pumping pipe 23 caused by water flow impact or operation during sampling, maintaining the stability of the pumping pipe 23 and ensuring smooth water intake. A counterweight block 29 is threadedly connected to the end of the pumping pipe 23, and a filter screen 210 is threadedly connected to the counterweight block 29. The filter screen 210 is made of stainless steel and can filter impurities in seawater, preventing pipe blockage or sample contamination. Several sets of buoys 28 with the same spacing are detachably installed on the pumping pipe 23. The buoys 28 are located between the buffer sleeve 27 and the counterweight block 29. An electric push rod 212 is detachably installed on the left side of the fixing base 21, and a clamping block 213 that limits the position of the drain pipe 211 is detachably installed at the output end of the electric push rod 212.

[0023] A cleaning component 3 for cleaning the sampling cylinder 4 is provided on the left side of the upper surface of the base 1. The cleaning component 3 includes a fixing plate 31 fixedly installed on the top left side of the base 1. A limit sleeve 32 is fixedly installed on the top of the fixing plate 31. A first servo motor 33 is detachably installed on the bottom of the fixing plate 31 by bolts. A first switch 331 for controlling the start and stop of the first servo motor 33 is fixedly installed on the fixing plate 31. A second screw 34 is detachably installed on the output end of the first servo motor 33 by a coupling. The end of the second screw 34 is rotatably connected to the limit sleeve 32. A lifting plate 36 is rotatably connected to the second screw 34. A sliding groove 361 is provided on the fixing plate 31. A slider 3 is vertically slidably connected in the sliding groove 361. 62. The slider 362 is fixedly installed on the side wall of the lifting plate 36; it guides the vertical movement of the lifting plate 36, ensuring that it rises and falls stably along a straight line under the drive of the first servo motor 33, and avoids deviation; it restricts the rotational freedom of the lifting plate 36, ensuring that the stirring rod 37 is accurately aligned with the sampling cylinder 4, and improving the stability and reliability of the cleaning process; the top of the lifting plate 36 is detachably installed with a second servo motor 35 by bolts, and the side wall of the lifting plate 36 is fixedly installed with a second switch 351 for controlling the start and stop of the second servo motor 35. The output end of the second servo motor 35 is threadedly connected to the stirring rod 37 through a coupling, and the side wall of the stirring rod 37 is adhered with cleaning cotton 38. The stirring rod 37 is located directly above the sampling cylinder 4.

[0024] Working principle:

[0025] According to the target sampling depth, a corresponding number of buoys 28 are installed on the pumping pipe 23. The buoys 28 are hollow and lightweight structures that provide upward buoyancy, while the counterweight 29 at the end of the pumping pipe 23 provides downward gravity. The two are in balance: the more buoys 28 there are, the greater the buoyancy, and the shallower the pumping pipe 23 sinks; conversely, the fewer buoys 28 there are, the more gravity of the counterweight 29 dominates, and the deeper the pumping pipe 23 sinks, thus achieving precise positioning of a specific water layer. Rotating the two sets of first screws 25 on the fixed base 21 can adjust the front and rear positions of the adjusting plate 26, and then adjust the angle of the pumping pipe 23 through the buffer sleeve 27 to ensure that it sinks perpendicular to the sea surface, avoiding depth errors caused by angle deviation. The buffer sponge pad inside the buffer sleeve 27 can reduce the friction between the pumping pipe 23 and the sleeve body, while absorbing the vibration generated by the water flow impact, protecting the pipe body and maintaining sampling stability.

[0026] Start the water pump 22. The water pump 22 generates negative pressure through the water pump pipe 23. Seawater enters from the end of the water pump pipe 23. At this time, the stainless steel filter screen 210 on the counterweight block 29 can filter impurities in the seawater to avoid clogging the pipe or contaminating the sample. After the extracted seawater is pressurized by the water pump 22, it is discharged into the sampling cylinder 4 through the drain pipe 211. The electric push rod 212 on the fixed base 21 can drive the clamping block 213 to clamp the drain pipe 211 to prevent the drain pipe 211 from shaking under the impact of the water flow and ensure that the seawater flows steadily into the sampling cylinder 4. The sampling volume can be observed through the scale line 41 on the sampling cylinder 4. After the target volume is reached, the water pump 22 is turned off and the winding reel 24 is rotated to wind and recycle the water pump pipe 23. The buoy 28 can reduce the tangling of the water pump pipe 23 during the recycling process and improve the convenience of operation.

[0027] After sampling is completed, open the rotating drain port 42 at the bottom of the sampling tube 4 to drain the seawater sample inside the tube. After closing the drain port, inject an appropriate amount of clean water or cleaning solution into the sampling tube 4. Press the first switch 331 on the fixed plate 31 to start the first servo motor 33. The output end of the first servo motor 33 drives the second screw 34 to rotate through the coupling. Since the second screw 34 is threadedly connected to the lifting plate 36, and the lifting plate 36 is slidably connected to the sliding groove 361 of the fixed plate 31 through the slider 362, the rotation of the screw will be converted into the vertical downward movement of the lifting plate 36 until the stirring rod 37 is fully inserted into the sampling tube 4. Press the second switch 351 on the lifting plate 36 to start the second servo motor 35. The output of the second servo motor 35 drives the stirring rod 37 to rotate at high speed through the coupling. The cleaning cotton 38 on the side wall of the stirring rod 37 will come into full contact with the inner wall of the sampling cylinder 4. The friction removes the seawater impurities, microorganisms and other residues on the cylinder wall. During the cleaning process, the clean water forms a vortex under the rotation of the stirring rod 37, which further enhances the cleaning effect and ensures that there are no residues on the inner wall of the sampling cylinder 4.

[0028] After cleaning, turn off the second servo motor 35, reverse the operation of the first switch 331, so that the first servo motor 33 drives the second screw 34 to rotate in the opposite direction, the lifting plate 36 rises and resets, the stirring rod 37 disengages from the sampling cylinder 4, and the rotating drain port 42 is opened again to discharge the cleaning wastewater, thus completing the entire cleaning process.
