[0027] Reference Figures 1 to 3, which is the first embodiment of the utility model, and the embodiment provides a water quality sampling drone that can take samples multiple times, including a sampling component 1 including a bottom box 11, a sampling module 12, a peristaltic pump 13, a pointing module 14, a cleaning module 15, and a machine bottom 16. The bottom box 11 is fixedly arranged at the bottom end of the machine bottom 16, the pointing module 14 rotates the bottom end of the machine bottom 16, the cleaning module 15 is arranged inside the bottom box 11, the sampling module 12 is arranged at the bottom end of the pointing module 14, and the peristaltic pump 13 is arranged at the side end of the pointing module 14. The classification component 2 includes a test tube warehouse 21, a test tube 22, a sample separation module 23, and a drainage trough 24. The test tube warehouse 21 is fixedly arranged inside the bottom box 11, the test tube 22 is arranged inside the test tube warehouse 21 for plugging and unplugging, and the sample separation module 23 is arranged at the test tube warehouse 21. Inside the tube bin 21, a drainage trough 24 is opened at the bottom of the bottom box 11. When the drone descends to the upper end of the water surface for sampling, the pointing module 14 is first driven to extend the sampling module 12 to the designated underwater area, and then the water quality sample is collected into the test tube 22 in the test tube bin 21 through the peristaltic pump 13 (then the sampling module 23 switches the test tube 22 so that it can receive the water quality sample of the new area again). During this period, the sample water overflowed during the sampling module 12 being transported to the test tube 22 can be discharged out of the drone bottom box 11 through the drainage trough 24, and then the cleaning module 15 works to transport clean water to the sampling module 12 to clean the sampling module 12, and then the clean water is discharged by reversing the peristaltic pump 13. The drone arrives at the next area and continues sampling.

[0028] Specifically, the sampling module 12 includes a water suction pipe 12a, a water pump box 12b, and a rubber head 12c. The water suction pipe 12a is rotatably arranged at the bottom end of the bottom box 11, the water pump box 12b is installed at the side end of the water suction pipe 12a, the rubber head 12c is plugged and arranged at the bottom end of the water suction pipe 12a, and the peristaltic pump 13 is fixedly installed inside the water pump box 12b. The pointing module 14 includes a placement frame 14a, a motor 14b, a gear 14c, and a gear bar 14d. The placement frame 14a is fixedly arranged inside the bottom box 11, the motor 14b is rotatably arranged inside the placement frame 14a, the gear 14c is fixedly arranged at the front end of the motor 14b, and the gear bar 14d is meshingly arranged at the lower end of the gear 14c. The water suction pipe 12a is fixedly installed on the side end of the gear bar 14d. The cleaning module 15 includes a water tank 15a, a connecting pipe 15b, and a switch door 15c. The water tank 15a is fixedly arranged inside the bottom box 11, the connecting pipe 15b is fixedly arranged at the front end of the water tank 15a, one of the connecting pipes 15b is connected to the water suction pipe 12a, the switch door 15c is arranged between the two connecting pipes 15b, the switch door 15c is connected to the water suction pipe 12a and the connecting pipe 15b, the switch door 15c includes an annular door frame 15ca, a sliding plate 15cb, a toggle block 15cc, a rubber sheet 15cd, a friction spring 15ce, and an electromagnet 15cf. The annular door frame 15ca is fixedly arranged at the bottom of the connecting pipe 15b, the rubber sheet 15cd is filled and arranged inside the annular door frame 15ca, and the sliding plate 15cb is rotatably arranged. On the inner side of the rubber sheet 15cd, the toggle block 15cc is fixedly arranged at the side end of the sliding plate 15cb, the friction spring 15ce is fixedly arranged between the annular door frame 15ca and the toggle block 15cc, and the electromagnet 15cf is fixedly arranged at the side end of the placement frame 14a. When the drone is located at the upper end of the sampling area, the motor 14b in the placement frame 14a is driven, and the motor 14b rotates to drive the gear 14c, and the gear 14c rotates to drive the gear bar 14d to rotate, so that the water suction pipe 12a tied with the gear bar 14d can be rotated, so that the rubber head 12c at the front section of the water suction pipe 12a can be extended to the designated sampling area (the rubber head 12c is flexible and can adapt to the changing conditions underwater), and then the user drives the water suction pipe 12a to rotate. The peristaltic pump 13 in the pump box 12b starts to extract water quality samples, and sends the water quality samples into the test tube 22 through the sampling module 23. Then the sampling module 23 switches the test tube 22 to wait for the next sampling. When the drone sends the sample into the test tube 22, the electromagnet 15cf is started, and the electromagnet 15cf attracts the toggle block 15cc. When the toggle block 15cc drives the sampling module 23 to rotate and switch the test tube 22, it will also drive the sliding plate 15cb to rotate in the annular door frame 15ca, thereby opening the water tank 15a. The water tank 15a sends clean water into the water suction pipe 12a through the connecting pipe 15b, and discharges the clean water by reversing the peristaltic pump 13 to achieve the purpose of cleaning the water suction pipe 12a. Then the drone arrives at the next working area for sampling.

[0029] Example 2

[0030] Reference Figures 1 to 5 As shown, it is the second embodiment of the utility model, which is different from the previous embodiment in that: the sample separation module 23 includes a fixed disk 23a, a sample feeder 23b, a sample collection port 23c, a fixed block 23d, a coil spring 23e, and a rotating table 23f. The sample feeder 23b is arranged at one end of the water suction pipe 12a located at the bottom box 11, the fixed disk 23a is fixedly arranged inside the bottom box 11, the rotating table 23f is rotatably arranged at the rear end of the fixed disk 23a, one end of the coil spring 23e is fixedly arranged at the center of the fixed disk 23a, and the other end of the coil spring 23e is fixedly arranged at the side end of the rotating table 23f, the sample collection port 23c is opened on the fixed disk 23a, and the sample collection port 23c is also opened on the rotating table 23f, the test tube 22 is plugged into the rotating table 23f, and the fixed block 23d is fixedly arranged at the sample collection port of the rotating table 23f. At the side end 23c, the fixed block 23d and the toggle block 15cc are toggled together, and the test tube is inserted into the sample collecting port 23c of the rotating table 23f. The user can also take out and replace the test tube 22 through the drainage groove 24 in the bottom box 11. The test tube 22 adopts a medical test tube with a rubber head. After the suction tube 12a transfers the sample to the test tube 22, the electromagnet 15cf starts to absorb the toggle block 15cc, and the toggle block 15cc toggles the fixed block 23d, and the toggle block 15cc and the fixed block 23d are out of contact. Under the action of the coil spring 23e, the rotating table 23f drives the test tube 22 to rotate (at this time, the electromagnet 15cf is powered off, and the toggle block 15cc is reset under the action of the friction spring 15ce and clamps the fixed block 23d again, so as to achieve the purpose of cleaning the suction tube 12a and switching the test tube).

[0031] Furthermore, the sample delivery device 23b includes a socket spring 23ba, a socket block 23bb, and a conical hollow column 23bc. The socket spring 23ba is fixedly arranged at one end of the suction pipe 12a located at the bottom box 11, the socket block 23bb is fixedly arranged at the other end of the socket spring 23ba, and the conical hollow column 23bc is fixedly arranged at the front end of the socket block 23bb. The socket spring 23ba at the top of the suction pipe 12a will push the socket block 23bb and the conical hollow column 23bc to pierce the rubber head end of the front section of the test tube 22. After the water pipe 12a completes transporting the sample into the test tube 22, the electromagnet 15cf is started so that when the test tube 22 is switched, the test tube 22 will squeeze the conical hollow column 23bc through the sample collecting port 23c, so that the test tube 22 can be switched smoothly. Subsequently, the toggle block 15cc is reset under the action of the friction spring 15ce and locks the fixed block 23d again. Then, the conical hollow column 23bc is inserted into the new test tube 22 along the sample collecting port 23c under the action of the socket spring 23ba, so that the new test tube 22 is aligned with the sample collecting port 23c.

[0032] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
