[0067] In the embodiment, in order to facilitate the sampling personnel to observe the remote control boat 1, the remote control boat 1 is provided with a monitoring camera, and the remote control boat 1 is also provided with a positioner, which facilitates the sampling personnel to determine whether the remote control boat 1 is moved to the position.

[0068] It should be noted that the remote control boat 1, the heating digestion mechanism 3 and the dosing detection mechanism 5 all belong to mature prior art, and will not be described in detail.

[0069] In an embodiment, the pump suction mechanism 2 comprises:

[0070] The water pump 21 is provided with a multi-way valve at the liquid outlet end, and the water pump 21 is used for pumping water samples and conveying the water samples to different directions by switching the multi-way valve;

[0071] The telescopic pipe assembly 22 is connected to the liquid inlet end of the water pump 21 at one end and inserted into the water body at the other end, and is used for changing the height of the water pump 21 to suck the water sample;

[0072] The telescopic control assembly 23 is used for controlling the telescopic length of the telescopic pipe assembly 22.

[0073] In this way, by placing the remote control boat 1 in the water body required for sampling, the remote control boat 1 is controlled to move to the sampling point, then according to the sampling height required at the point, the telescopic control assembly 23 is controlled to change the telescopic length of the telescopic pipe assembly 22, so that the telescopic pipe assembly 22 is telescoped and inserted into the corresponding water layer height, then the water sample of the water layer can be pumped out by the water pump 21, and the water sample can be collected by receiving the water sample at the water outlet end.

[0074] In an embodiment, the telescopic pipe assembly 22 comprises at least two sleeves 221 which are mutually sleeved and movable along the axial direction, one of the sleeves 221 is connected to the liquid inlet end of the water pump 21, and the sleeve 221 is provided with a anti-drop ring 222 inserted into the adjacent sleeve 221, and a sliding groove is formed in the corresponding sleeve 221 for the anti-drop ring 222 to move along the axis;

[0075] The telescopic control assembly 23 comprises a winding motor and a winding roller arranged at the output end of the winding motor, and a winding rope is detachably arranged on the winding roller. The winding rope is fixedly connected to the outermost sleeve 221 of the telescopic pipe assembly 22 at the end away from the winding roller.

[0076] In this way, the sleeves 221 are sleeved with each other. Due to the self-weight of the sleeves 221, the sleeves 221 will automatically fall and elongate when not limited. The anti-disengagement ring 222 is used to limit the complete disengagement of the adjacent two sleeves 221 during telescopic adjustment, so that the telescopic pipe assembly 22 can be freely adjusted in length within the maximum adjustment range. Since the sleeves 221 are hard pipes, they will not be affected by the water flow to deviate from the measurement point, and will not be affected by the water bottom grass to be unable to move telescopically. The use stability is high. Since the outermost sleeve 221 is connected to the winding rope, the maximum length that the sleeves 221 can elongate depends on the length of the winding rope, so that the number of revolutions of the output end of the winding motor can be controlled to quickly adjust the length of the telescopic pipe assembly 22.

[0077] It should be noted that, in order to prevent the water body of the non-required water layer from entering from the gap between the adjacent sleeves 221, the anti-disengagement ring 222 is provided with a sealing ring abutting against the adjacent sleeves 221, and in order to ensure that the sleeves 221 can normally move up and down, the top of each sleeve 221 provided with a sliding groove is also provided with a pressure stabilizing hole communicating with the sliding groove.

[0078] In an embodiment, one of the liquid outlets of the multi-way valve is provided with a liquid outlet assembly 24 capable of changing the liquid outlet position, and the liquid outlet assembly 24 is located directly above the heating and digestion mechanism 3.

[0079] The liquid outlet assembly 24 comprises a liquid outlet pipe 241 rotatably arranged at one of the liquid outlets of the multi-way valve. The liquid outlet pipe 241 is in an inverted U shape, and the liquid outlet pipe 241 is provided with a driven gear 242 capable of rotating with the liquid outlet pipe 241. The liquid outlet assembly 24 further comprises an angle adjustment motor 243 and a driving gear 244 arranged at the output end of the angle adjustment motor 243. The driven gear 242 and the driving gear 244 are in meshing relationship.

[0080] In this way, the angle adjustment motor 243 is rotated to rotate the liquid outlet pipe 241 under the cooperation of the driven gear 242 and the driving gear 244, so as to change the liquid outlet position. Therefore, the remote control boat 1 can be provided with fixed water sample collection positions and waste liquid discharge positions. After the water sample collection at one of the positions is completed, the liquid outlet position of the liquid outlet pipe 241 can be changed to make the subsequent discharged liquid discharged to the waste liquid discharge position first, so as to discharge the original water sample remaining in the liquid outlet pipe 241 as waste liquid, and then the liquid outlet pipe 241 is rotated to the water sample collection position again for the collection of the subsequent water sample.

[0081] In the embodiment, the water guide plate 9 is arranged on the remote control boat 1 at the waste liquid discharge position, and is used to guide the waste water to be discharged in the direction in which the remote control boat 1 sails away, so that the discharged waste liquid does not affect the collection of the subsequent water sample.

[0082] In an embodiment, the heat exchange mechanism 4 comprises an internally hollow shell 41, a drain pipe 42 arranged at the bottom of the shell 41 and communicating with the inside of the shell 41, a heat exchange piece 43 arranged at the top of the shell 41 and capable of moving up and down, the region between the shell 41 and the heat exchange piece 43 being a heat exchange chamber, and a water inlet pipe 44 arranged at the top of the shell 41 and communicating with the heat exchange chamber, one end of the water inlet pipe 44 being connected with one of the liquid outlet ends of the multi-way valve;

[0083] The heat exchange piece 43 comprises an internally hollow inner cylinder 431 and a plurality of heat dissipation fins 432 arranged on the inner cylinder 431, the inside of the inner cylinder 431 being a water containing cavity, the inner cylinder 431 and the heat dissipation fins 432 being inserted into the shell 41, the shell 41 being provided with an insertion hole for the insertion of the inner cylinder 431 and the heat dissipation fins 432, and a sealing strip being arranged in the insertion hole and abutting against the inner cylinder 431 and the heat dissipation fins 432, at least one convex strip 433 being arranged at the top end of the inner cylinder 431, a first compression spring 434 being arranged between the convex strip 433 and the shell 41, the bottom end of the inner cylinder 431 being flush with the top of the inner cavity of the shell 41 when the first compression spring 434 is in a natural state, and a taking and placing hole being arranged at the top of the inner cylinder 431 and being used for the insertion of the digestion pipe into the inner cylinder 431, the digestion pipe moving mechanism 7 driving the digestion pipe to enter the water containing cavity and then continuing to move downward to press the first compression spring 434 and push the heat exchange piece 43 into the shell 41.

[0084] In this way, the digestion pipe needing to be cooled is moved into the water containing cavity of the heat exchange mechanism 4, so that the pure water in the water containing cavity wraps the digestion pipe and exchanges heat with the digestion pipe, then the heat in the water containing cavity is transferred to the heat exchange chamber, at the same time, the water pump 21 is used to draw the water of the detected water body and inject it into the heat exchange chamber to drive the water in the heat exchange chamber to flow circularly, so that part of the heat is taken away when the water flows out of the heat exchange chamber, thereby realizing rapid cooling, and the water used to enter the heat exchange chamber does not pollute the outer wall of the digestion pipe and affect the subsequent detection precision, and at the same time, the heat is rapidly transferred to the heat exchange chamber under the action of the heat dissipation fins 432, thereby accelerating the cooling, and because the bottom end of the inner cylinder 431 is flush with the top of the inner cavity of the shell 41 when the first compression spring 434 is in a natural state, the inner cylinder 431 only moves downward together with the digestion pipe after the insertion of the digestion pipe, enters the heat exchange chamber, and then moves upward to reset under the pushing of the first compression spring 434 after the digestion pipe is removed, and in the upward movement process, the sealing strip is used to scrape off the adhering matters on the heat dissipation fins 432, thereby ensuring that the heat dissipation fins 432 can maintain the heat conduction efficiency in the next heat exchange.

[0085] It should be noted that, in order to avoid the liquid in the heat exchange chamber from leaking out of the gap between the sealing strip and the heat exchange element 43, a sealing cover can be arranged at the top of the inner cylinder 431. When the digestion tube is cooled, the sealing cover tightly abuts the top of the shell 41, forming a double-layer plugging with the sealing strip, thereby improving the sealing effect. At the same time, when the digestion tube is removed from the water tank, a small amount of pure water will be taken away. In order to ensure that the stable cooling effect can be maintained for a long time, the pure water in the water tank needs to be replenished regularly.

[0086] In an embodiment, the flushing mechanism 6 includes a turnover assembly 61 for driving the digestion tube to turn over and a water spraying assembly 62 for flushing the digestion tube after the turnover assembly 61 turns over;

[0087] The turnover assembly 61 includes a turnover motor 611 and a rotating disc 612 driven by the turnover motor 611 to rotate longitudinally. The rotating disc 612 is provided with a first clamping and locking part 613 located directly above the water spraying assembly 62, which is used for detachable connection with the digestion tube.

[0088] The water spraying assembly 62 includes a hollow telescopic spray rod which can move telescopically.

[0089] In this way, after the first clamping and locking part 613 is fixed with the digestion tube, the digestion tube can be turned over, so that the hollow telescopic spray rod can be inserted into the digestion tube for flushing, thereby further improving the flushing effect.

[0090] It should be noted that the hollow telescopic spray rod is provided with a water storage tank 8 with an open top, which is used to store the waste liquid sprayed by the water spraying assembly 62 through the hollow telescopic spray rod, so that the waste liquid generated by flushing will not be randomly discharged, but will be collected and temporarily stored in the water storage tank 8, and then be treated uniformly.

[0091] In an embodiment, the digestion tube moving mechanism 7 includes a displacement part 71 for driving the digestion tube to displace and a first telescopic part 72 for driving the digestion tube to move up and down.

[0092] The displacement part 71 includes a rotating motor 711 and a hollow tube 712 located at the top of the rotating motor 711 and driven by the first telescopic part 72 to move up and down.

[0094] In this way, the digestion tube can be moved up and down by the displacement component 71 to move in and out of the inner cylinder 431, and can also be rotated, so that the cooled digestion tube can be automatically transferred to the remaining detection stations, or the digestion tube that needs to be cooled can be taken from the water injection and digestion station, and the cooperation of the rectangular bar 724 and the box cover allows one end of the rectangular bar 724 to be inserted into the electric telescopic rod 721, limiting the rotation of the electric telescopic rod 721 without affecting the telescopic movement of the electric telescopic rod 721, so that when the rotary motor 711 drives the hollow tube 712 and the digestion tube arranged thereon to rotate, the electric telescopic rod 721 will not rotate, and when the rotary motor 711 drives the digestion tube to rotate to the bottom of the gland 722, the electric telescopic rod 721 can be retracted to move the gland 722 downward to push the hollow tube 712 and the mounting frame 713 downward, so that the digestion tube moves into the inner cylinder 431, and the opening at the top of the digestion tube is blocked by the gland 722, so that the digestion tube is cooled while avoiding contamination of the liquid inside the digestion tube.
