DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] See also Figure 1-Figure 5 The utility model provides the following technical solutions: a water quality detection device convenient for sampling, comprising a lower box body 1, an upper box body 2 hinged on the top of the lower box body 1, and a detection assembly 3 arranged in the lower box body 1, the detection assembly 3 comprising: a base 31, a water quality measuring instrument 32, a sample carrying mechanism 33, a sampling mechanism 34 and a detection mechanism 35; the water quality measuring instrument 32 is fixed on the base 31; the sample carrying mechanism 33 comprises a turntable 331 rotatably arranged on the base 31 and a plurality of sample cups 335 equidistantly arranged on the turntable 331 along the circumferential direction; the sampling mechanism 34 comprises a rotating A winding roller 341, a water suction hose 345, a counterweight tube 346, a small water suction pump 347 and a hard tube 348 are arranged on the base 31. An L-shaped flow channel 344 is opened in the winding roller 341. One end of the water suction hose 345 is connected to the L-shaped flow channel 344, and the other end is fixed to the counterweight tube 346. The water inlet port of the small water suction pump 347 is connected to the L-shaped flow channel 344 by a rotating joint, and the water outlet port is fixed to the hard tube 348. The detection mechanism 35 includes a detection head 351 movably arranged on the base 31. The detection head 351 is located directly above the sample cup 335 and moves in the vertical direction.

[0043] It should be noted that the water quality meter 32 used in the present invention is a conventional device purchased on the market, such as the water quality meter 32 with model KYS-200W, and its working principle is a well-known prior art, which will not be described in detail here. In addition, the rotary joint connecting the water inlet end of the small water pump 347 and the L-shaped flow channel 344 is also a conventional device purchased on the market, and its internal structure is a well-known prior art, which will not be described in detail here.

[0044] It should be further explained that a rechargeable lithium battery is provided in the lower box 1 of the utility model for supplying power to the water quality detection device.

[0045] Further, by Figure 1-Figure 5 As shown, the release length of the water suction hose 345 can be adjusted by rotating the winding roller 341 to extract water source samples at different depths. The counterweight tube 346 ensures that the lower end of the water suction hose 345 can sink into the water source. When the winding roller 341 is rotated, the presence of the rotating joint ensures that the hard tube 348 will not rotate with the winding roller 341. The sample is extracted by the small water pump 347 and transferred to the sample cup 335 through the water suction hose 345, the L-shaped flow channel 344, the rotating joint, the small water pump 347 and the hard tube 348.

[0046] Further, by Figure 1-Figure 3 As shown, the sample cups 335 can rotate along with the rotation of the turntable 331 , so that different sample cups 335 can receive samples. The rotation of the turntable 331 also transfers different sample cups 335 to the detection mechanism 35 .

[0047] Further, by Figure 1 , Figure 2 and Figure 5 As shown, the detection head 351 is moved down and inserted into the sample cup 335 to achieve water quality measurement. After the measurement is completed, the detection head 351 is raised and reset, and the turntable 331 is rotated to transfer different sample cups 335 to the detection mechanism 35, and then the detection head 351 is moved down and inserted into the sample cup 335 to measure the water quality, and multiple groups of measurements are repeated.

[0048] Depend on Figure 1-Figure 3 As shown, the sample supporting mechanism 33 also includes: a servo motor No. 332 and a support basket 334. The servo motor No. 332 is fixed on the base 31, and the turntable 331 is fixed on the output shaft of the servo motor No. 332. A plurality of placement holes 333 evenly spaced along the circumferential direction are provided on the turntable 331. The support basket 334 is fixed on the bottom surface of the turntable 331 at positions corresponding to the placement holes 333. Therefore, placing the sample cup 335 in the placement hole 333 and supporting it with the support basket 334 has higher stability. The servo motor No. 332 provides power for the rotation of the turntable 331.

[0049] Depend on Figure 1 , Figure 2 and Figure 4 As shown, the sampling mechanism 34 also includes: a perforated support ear 342, a second servo motor 343 and a bracket 349. The two perforated support ears 342 are symmetrically fixed on the base 31. The winding roller 341 is rotatably installed between the two perforated support ears 342. The second servo motor 343 is fixed on the perforated support ear 342 to drive the winding roller 341 to rotate. The bracket 349 is fixed on the base 31 to support the hard tube 348. The second servo motor 343 provides power for the winding roller 341 to rotate, and can accurately control the release length of the suction hose 345. The hard tube 348 is used to accurately transport the sample into the sample cup 335. The bracket 349 is used to support the hard tube 348 to ensure that the hard tube 348 does not rotate when the winding roller 341 rotates.

[0050] Depend on Figure 1 , Figure 2 and Figure 5 As shown, the detection mechanism 35 also includes: a lifting plate 352, which is arranged on the base 31 and has the freedom of movement in the vertical direction. The detection head 351 is fixed on the lifting plate 352, and the detection head 351 is connected to the water quality meter 32 via a data transmission line.

[0051] Further, by Figure 1 , Figure 2 and Figure 5 As shown, the detection mechanism 35 also includes: a top plate 354, a threaded column 355 and a No. 3 servo motor 356. The top plate 354 is supported and fixed on the base 31 by a support column 353, and the support column 353 passes through the lifting plate 352. The threaded column 355 is rotatably installed between the base 31 and the top plate 354, and the threaded column 355 passes through the lifting plate 352 and is connected to the lifting plate 352 by threaded engagement. The No. 3 servo motor 356 is fixed on the top plate 354 to drive the threaded column 355 to rotate. The No. 3 servo motor 356 is started to drive the threaded column 355 to rotate. Under the action of the threaded engagement, the lifting plate 352 drives the detection head 351 to move in the vertical direction.

[0052] Depend on Figure 1 , Figure 2 and Figure 5As shown, the detection mechanism 35 also includes: a fixing frame 357, a cleaning plate 358 and a rubber sheet 3591. The fixing frame 357 is fixed on the base 31, the cleaning plate 358 is fixed on the top of the fixing frame 357, and a circular hole 359 is opened on the cleaning plate 358. The circular hole 359 is located directly below the detection head 351. The rubber sheet 3591 is fixed in the circular hole 359, and a cleaning hole 3592 is opened on the rubber sheet 3591. The diameter of the cleaning hole 3592 is smaller than the diameter of the detection head 351. When the detection head 351 moves downward, it will pass through the cleaning hole 3592 of the rubber sheet 3591. At this time, the cleaning hole 3592 produces elastic expansion. After the detection head 351 moves up and resets, the cleaning hole 3592 is restored. The water sample on the detection head 351 can be scraped off through the cleaning hole 3592 to avoid affecting subsequent detection and ensure the accuracy of the detection.

[0053] Depend on Figure 1 As shown, a handle 4 is fixed on the upper box body 2 to facilitate the carrying of the detection device and to facilitate its use in different occasions.
