Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

A multi-water sample continuous detection device and detection method thereof as described in accompanying drawings 1-2, comprising a sample placement platform 1, on which a number of detection water samples 2 are placed on the placement platform 1, and one side of the sample placement platform 1 A stand structure 3 is provided, and a lifting module 4 is slidably arranged on the stand structure 3, and a conversion structure 5 is installed on the lift module 4, and a number of detection devices are arranged around the outside vertical plane of the conversion structure 5. Probe 6, the detection probe 6 located directly below is arranged perpendicular to any of the detection water samples 2, surrounds the outside of the conversion structure 5, and is sequentially provided with washing modules along the rotation direction of a plurality of detection probes 6 7. The dissolving module 8 and the drying module 9, wherein, the washing module 7 and the dissolving module 8 are coaxially sleeved with any of the detection probes 6 and arranged in relative sliding cooperation, and the lifting module 4 is correspondingly provided with A guide structure 10 for sliding fit between the flushing module 7 and the dissolving module 8 .

This solution rotates and replaces different probes to correspond to the detection samples through the conversion structure, and the sample placement platform can be in the form of a turntable or a mobile platform, so that multiple water samples can be corresponding to the detection stations in turn, and the detection probes after use can be converted. After the structure is rotated to adjust the position, it corresponds to the washing module 7, the dissolving module 8 and the drying module 9 in sequence, so that when the probe is replaced for continuous detection, the cleaning operation of the remaining probes is completed synchronously, ensuring that the cleaning operation is completed after the probe rotates one week , can be re-invested in the detection operation, so that continuous and efficient water sample detection operations can be realized, and mutual pollution will not occur between water samples, and the efficiency of continuous detection of multiple water samples is improved on the premise of ensuring the accuracy of detection data .

Since the cleaning operation is carried out synchronously with the detection operation, each probe cannot be in a cooperative state with any module components during the probe conversion. However, it is difficult to ensure the thorough cleaning of the probe after a period of time. Therefore, this plan divides the cleaning operation into multiple parts. In this way, the cleaning operation time for one probe is distributed to multiple detection operation time periods to complete, and multiple probes can be simultaneously cleaned in different stages, so that it will not affect the efficiency of detection. The continuity of detection is guaranteed.

In terms of function, this scheme divides the cleaning operation into three steps: rough rinsing, fine dissolution, and drying, and the functions are respectively distributed in the three modules of the rinsing module 7, the dissolving module 8 and the drying module 9. Among them, firstly, through The flushing module performs rapid high-pressure flushing on the sample residue on the surface of the probe. At this stage, some substances that are easily soluble in water or have low adhesion strength are quickly processed; and then pressurized and stirred by the dissolution module, so that the surface of the probe may be difficult to adhere to. Soluble substances or substances with strong adhesion force fall off or dissolve quickly; finally, the moisture on the surface of the probe is dried by the drying module for subsequent detection.

As a preferred embodiment: the flushing module 7 and the dissolving module 8 both include a chamber body 11, the chamber body 11 is coaxially sleeved relative to the corresponding detection probe 6, and one end of the chamber body 11 is sealed A corresponding nozzle assembly is provided, and the other end of the chamber body 11 is sealed with a liquid pumping structure 13, and the liquid pumping structure 13 is arranged in a sealed sleeve with respect to the root of the corresponding detection probe 6, and the liquid pumping structure 13 passes through The moving seat 14 is slidingly matched with the guide structure 10 .

Among them, the end of the tank body in the flushing module is sealed with nozzles with multiple high-pressure nozzles, which are mainly used to flush the surface of the probe through high-pressure water columns; the pumping structure includes a ring-shaped liquid collection tank set relative to the root of the probe , the side wall of the sump is communicated with a pump tube for pumping liquid.

The dissolving module 8 includes a dissolving spray head 81, the nozzle 811 in the middle of the dissolving spray head 81 is set opposite to the end of the detection probe 6, and the dissolving spray head 81 is slidably arranged relative to the inner wall of the corresponding chamber body 11. The dissolving nozzle 81 is fixedly connected to the mobile mounting plate 82, and the mobile mounting plate 82 is arranged in sliding cooperation with the corresponding guide structure 10, and the distance between the mobile mounting plate 82 and the corresponding mobile seat 14 can be adjusted through the telescopic adjustment rod 83 set up.

The chamber body 11 of the dissolving module 8 is arranged to rotate relative to the seal corresponding to the liquid pumping structure 13 , the chamber body 11 is driven to rotate by a power device 84 , and the inner wall of the chamber body 11 is provided with a stirring structure 85 .

The water inlet end 812 of the dissolving nozzle 81 is coaxially fixed to the output end of the power unit 84, and the water inlet end 812 is connected to the outer wall of the warehouse body 11 through an adapter frame 86, and the adapter frame 86 and the warehouse body 11 are set in a circumferential limit and slide relative to each other in the axial direction.

The water inlet end 812 is connected to the water inlet pipe 88 through a transfer tee 87, and the transfer tee 87 includes a branch pipe communicating with the water inlet pipe 88 and a main pipe sleeved outside the water inlet end 812. The inner annular cavity of the main pipe communicates with the nozzle 811 through a plurality of through holes and an inner through cavity.

Based on the above structure, when the probe corresponds to the dissolving module, firstly, the moving seat drives the entire dissolving module to be sleeved relative to the probe until the bottom pumping structure is sealed and sleeved relative to the root of the probe. Water injection, during the water injection process, the water column also washes the surface of the probe for a second time, and at the same time, the power device drives the chamber body to rotate relatively, thereby driving the internal stirring structure to stir the water body in the chamber body, making the substance more soluble in water and easier to relative to the probe The surface falls off, and at the same time, by driving the telescopic adjustment rod to shrink, the dissolving nozzle makes a piston movement relative to the inner wall of the chamber, thereby exerting pressure on the internal water body, making the substance more soluble in water, and within a certain period of time, the liquid in the chamber is quickly evacuated through the pumping structure , and finally drive the entire dissolving module out of the probe through the moving seat, and have a conversion structure to replace the probe.

The drying module 9 can be arranged at a parallel distance between two boards with heating wires, and the probe can be dried by letting the rinsed and dissolved probe pass between the two boards, and the drying module It does not need to be installed relative to the lifting module, but only needs to be installed at a fixed position relative to the stand structure. By setting the distribution area of the heating wire, it is also possible to realize synchronous heating of multiple probes, further improving cleaning efficiency and indirectly improving detection efficiency.
