During actual processing, multiple second limit seats 33 can be set through the connecting member 37, thereby increasing the number of samples sampled and further improving the accuracy of the sample monitoring data.

[0049] There are multiple groups of limit units 35, and the multiple groups of limit units 35 are distributed in a circular array with the center point of the first limit seat 32 or the second limit seat 33 as the center. The sampling bottle 34 is firmly limited by the multiple groups of limit units 35.

[0050] The limiting unit 35 includes a receiving groove arranged on the side wall of the first limiting seat 32 or the second limiting seat 33, one end of an extrusion piece 351 installed on the side wall of the receiving groove, one end of a push rod 352 installed at the other end of the extrusion piece 351, and a clamping plate 353 installed at the other end of the push rod 352. Preferably, the extrusion piece 351 is an extrusion spring, and the inner surface of the clamping plate 353 is provided with a rubber pad, which protects the sampling bottle 34 and prevents the surface of the sampling bottle 34 from being damaged due to excessive clamping force.

[0051] Among them, the displacement unit 36 ​​includes a driving member 361 installed at the bottom of the first limit seat 32, a gear 362 installed at the end of the output shaft of the driving member 361, a first rack plate 363 and a second rack plate 364 meshed with the outer side of the gear 362, and the first rack plate 363 and the second rack plate 364 are relatively installed on the inner wall of the supporting seat 31. Preferably, the driving member 361 is a servo motor. When the driving member 361 is working, it will drive the gear 362 to rotate. Since the gear 362 is meshed with the first rack plate 363 and the second rack plate 364, the first limit seat 32 slides along the length direction of the first rack plate 363 and the second rack plate 364.

[0052] Among them, the lifting member 43 includes a screw rod 431 installed on the outside of the vertical tube 42, and a sliding sleeve 432 threadedly connected to the outside of the screw rod 431. A guide rod 433 is installed on the outside of the vertical tube 42 relative to the screw rod 431. A movable sleeve 434 is movably connected to the outside of the guide rod 433.

[0053] The transmission unit 44 includes a double-headed motor 441 installed on the inner side of the hull 1, a transmission rod 442 installed at the end of the output shaft of the double-headed motor 441, a first bevel gear 443 installed on the outer side of the transmission rod 442, a second bevel gear 444 meshed with the side of the first bevel gear 443, a movable rod 445 installed in the middle of the second bevel gear 444, a third bevel gear 446 installed at the end of the movable rod 445, a fourth bevel gear 447 meshed with the side of the third bevel gear 446, a vertical rod installed in the middle of the fourth bevel gear 447, a driving gear 448 installed on the outer side of the vertical rod, and The driven gear 449 meshes with the side of the driving gear 448. The driven gear 449 is installed on the outside of the screw rod 431 and works through the double-headed motor 441 to drive the first bevel gear 443 to rotate. Since the first bevel gear 443 is meshed with the second bevel gear 444, the movable rod 445 is driven to rotate, thereby driving the third bevel gear 446 to rotate. Since the third bevel gear 446 is meshed with the fourth bevel gear 447, the vertical rod is driven to rotate, thereby driving the driving gear 448 to rotate. Since the driving gear 448 is meshed with the driven gear 449, the screw rod 431 is driven to rotate.

[0054] The filter unit 52 includes a fixed cylinder 521 installed between the extraction pipe 41 and the connecting pipe 51 and a filter screen 522 installed on the inner wall of the fixed cylinder 521. Preferably, the filter screen 522 has a conical structure. Fig.10 As shown in , the filter screen 522 is a conical structure which can improve its impact resistance, and when the impurities in the water source come into contact with the filter screen 522, they will slide down along the inclined surface of the filter screen 522, thus preventing the impurities from gathering and clogging in one place.

[0055] The conveying assembly 5 further includes an extraction pump 54 installed on the pipe wall of the connecting pipe 51 .

[0056] Among them, the drainage unit 53 includes a drainage pipe 531 installed at the bottom of the connecting pipe 51, one end of a telescopic pipe 532 movably connected to the inside of the drainage pipe 531, the other end of the telescopic pipe 532 extends through to the bottom of the drainage pipe 531, and a fixing ring is installed on the outer wall of the drainage pipe 531, and a lifting cylinder 533 is arranged between the fixing ring and the bottom of the connecting pipe 51.

[0057] The hull 1 in the device realizes its movement on the water surface through structures such as propellers and control devices in the prior art, which will not be described in detail here.

[0058] When the present invention is used, the device is first placed at the water source to be monitored, and then the buoyancy of the float box 2 makes the device float on the water surface, so that the water quality of any range of the water source can be monitored without restriction;

[0059] When sampling water quality, the extraction pump 54 works to create negative pressure inside the connecting pipe 51 and the extraction pipe 41, so that the water source enters the drain pipe 531 through the vertical pipe 42, the extraction pipe 41 and the connecting pipe 51, and then the lifting cylinder 533 works to push the fixing ring downward, thereby driving the telescopic pipe 532, so that the bottom of the telescopic pipe 532 squeezes the fan-shaped rubber pad into the interior of the sampling bottle 34, so that the water source passes through the telescopic pipe 532 and is discharged into the sampling bottle 34. When the sampling bottle 34 is full, the driving member 361 works to drive the gear 362 to rotate. Since the gear 362 is meshed with the first rack plate 363 and the second rack plate 364, the first limit seat 32 slides along the top of the bearing seat 31. When the first limit seat 32 slides, it drives the plurality of second limit seats 33 to slide through the connecting member 37, so that one of the second limit seats 33 drives the sampling bottle 34 to slide to the bottom of the telescopic pipe 532, thereby realizing multiple sampling of the same water source depth.

[0060] The sampling bottle 34 is limited and fixed by the elastic squeezing action of the squeezing member 351 in cooperation with the push rod 352 and the clamping plate 353, so that it is convenient for personnel to take or fix the sampling bottle 34;

[0061] When it is necessary to sample water quality at different depths, the double-headed motor 441 drives the transmission rod 442 to rotate, thereby driving the first bevel gear 443 to rotate. Since the first bevel gear 443 is meshed with the second bevel gear 444, the movable rod 445 is driven to rotate, thereby driving the third bevel gear 446 to rotate. Since the third bevel gear 446 is meshed with the fourth bevel gear 447, the vertical rod is driven to rotate, thereby driving the driving gear 448 to rotate. Since the driving gear 448 is meshed with the driven gear 449, the screw rod 431 is driven to rotate, so that the sleeve 432 slides along the outer side of the screw rod 431 under the action of the threaded pair, thereby driving the vertical pipe 42 to slide upward or downward, so as to sample water quality at different depths at the water source;

[0062] When the water source is transported through the transport assembly 5, the water source is filtered in cooperation with the filter screen 522 to prevent impurities from clogging the pipeline.

[0063] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
