[0035] Specifically, in actual operation, the process of testing water samples is as follows:

[0036] S01: Take out a reagent bottle from the reagent rack 2 using the reagent bottle moving device 1;

[0037] S02: using the reagent bottle mobile device 1 to absorb the water sample to be tested, and then injecting it into the taken out reagent bottle;

[0039] S04: the detection device 3 performs pre-treatment (for example, heating) on ​​the water sample in the reagent bottle before detection, and then performs detection and obtains detection data; and

[0040] S05: After the detection is completed, the reagent bottle containing the water sample is moved to the original position of the reagent rack 2 using the reagent bottle moving device 1.

[0041] Thus, in this way, in the process of detecting water samples, detection can be performed according to fixed steps through a whole set of interrelated equipment. And in the detection process, a mechanical structure (i.e., a reagent bottle mobile device) is used for operation, so as to achieve the technical effect that in the process of water sample detection, the detection can be completed according to a fixed process using interrelated equipment. On the premise of ensuring the accuracy of the detection data, time and manpower are saved and work efficiency is improved. This solves the technical problem that the water resource detection work efficiency is low because the water sample collection, water sample detection and water sample analysis are all performed using separate devices, and all steps cannot be performed through a set of devices.

[0042] Optionally, the water sample monitoring device further comprises a chassis 5 , wherein the chassis 5 is located below the table 4 , and a processor is disposed in the chassis 5 , and the processor is respectively connected to the reagent bottle mobile device 1 and the detection device 3 .

[0043] Specifically, refer to Figure 1 as well as Figure 2 As shown, the water sample detection device also includes a chassis 5, in which a processor (not shown) is arranged. The processor is connected to the reagent bottle mobile device 1 and the detection device 3 respectively, and the processor can control the reagent bottle mobile device 1 to move and collect water samples, and control the detection device 2 to perform water sample detection operations. Therefore, in the process of water sample detection, the processor can realize automatic control operations, reduce the dependence on manpower, and greatly improve work efficiency.

[0044] It should be added that in order for the processor to drive the reagent bottle moving device 1 and the detection device 3 to work, the chassis 5 is also provided with conventional devices such as a driver, a relay, a display screen, a temperature controller, a switching power supply, an emergency stop switch and a power switch.

[0045] Optionally, the detection equipment 3 includes: a circulation pool 31, configured to extract water samples from water resources and store them; a mixer 32, configured to mix the reagent bottle injected with the water sample to be detected; a digester 33, configured to digest the water sample to be detected in the reagent bottle after mixing; and a detector 34, configured to detect the digested water sample.

[0046] Specifically, refer to Figure 1 as well as Figure 3 As shown, the detection device 3 includes:

[0047] The circulation pool 31 is connected to the water source to be tested to keep the water source flowing. This ensures that the water sample collected by the reagent bottle mobile device 1 is fresh, ensuring the accuracy of the test results;

[0048] The mixer 32 may be provided with an eccentric rotating mechanism for mixing the reagent bottle injected with the water sample to be tested, so that the water sample to be tested is mixed more evenly, and the precipitation of substances in the water is avoided, so that the test result is more accurate;

[0049] The digester 33 is used to digest the water sample to be tested in the mixed reagent bottle, destroy the organic matter in the water sample, dissolve the suspended solids, and oxidize the elements to be tested in various valence states into a single high-valence state or transform them into inorganic compounds that are easy to separate, so that the results are more scientific and accurate; and

[0050] The detector 34 is used to detect the water sample after digestion (for example, absorbance detection) to obtain detection data.

[0051] Therefore, a complete set of relevant detection equipment can be used to carry out water sample detection, and the accuracy of the measured water sample data can be guaranteed.

[0052] Optionally, refer to Fig. 9 As shown, the processor is respectively connected to the circulation pool 31, the mixer 32, the digester 33 and the detector 34. Thus, through the processing of the processor, automatic water sample detection is achieved.

[0053] Optionally, the reagent bottle moving device 1 includes: a rotatable bracket 12, which is vertically arranged on the table 4; a screw rod 13, which is arranged on the rotatable bracket 12 and parallel to the rotatable bracket 12; and a robotic arm 11, which is arranged on the rotatable bracket 12 and coupled to the screw rod 13, and is configured to rise or fall relative to the rotatable bracket 12 through the rotation of the screw rod 13.

[0054] Specifically, Figure 4 A side view of the reagent bottle moving device 1 is shown, referring to Figure 4As shown, the device includes: a rotatable bracket 12, a screw rod 13 and a mechanical arm 11. The rotatable bracket is perpendicular to the table 4 (please refer to Figure 1 ), the screw rod 13 is arranged on the rotatable support 12 and is kept parallel to the rotatable support 12. The robot arm 11 is arranged on the rotatable support 12 and is coupled with the screw rod 13, and can be raised or lowered relative to the rotatable support 12 by the rotation of the screw rod 13.

[0055] In this way, the reagent bottle moving device 1 can be rotated horizontally and the mechanical arm 11 can be lifted and lowered vertically, thereby making the operations of picking up the reagent bottles and moving the reagent bottles more convenient.

[0056] Optionally, the reagent bottle moving device 1 further includes: a first rotation driving mechanism 14 for driving the rotatable bracket 12 to rotate; and a second rotation driving mechanism 15 disposed on the rotatable bracket 12 and for driving the screw 13 to rotate.

[0057] Specifically, refer to Figure 5 As shown, the first rotary drive mechanism 14 can be a stepper motor, which is connected with the rotatable reagent rack 12, and by the rotation of the stepper motor, the rotatable support 12 is driven to rotate. The second rotary drive mechanism 15 is installed on the inside of the rotatable support 12, and the second rotary drive mechanism 15 can be a stepper motor, which is connected with the screw rod 13, and by driving the screw rod 13 to rotate, the mechanical arm 11 can be controlled to rise or decline. Using a driving mechanism (that is, the first rotary drive mechanism and the second rotary drive mechanism) to drive can make the reagent bottle mobile device 1 move more accurately, saving manpower. And the angle and distance that the reagent bottle mobile device 1 can be moved by adopting a stepper motor can be controlled more accurately.

[0058] Optionally, the end of the robot arm 11 is provided with: a picker 112 configured to pick up a reagent bottle; and a sampler 111 configured to inject a water sample to be tested into the reagent bottle.

[0059] Specifically, refer to Figure 5 as well as Figure 6 As shown, the end of the mechanical arm 11 is provided with a picker 112 for picking up the reagent bottle and a sampler 111 for collecting the water sample. The picker 112 is used to pick up the reagent bottle from the reagent rack 2 (here can refer to Figure 1 ) to take and place the reagent bottle and move the reagent bottle. The sampler 111 is used to absorb the water sample to be tested and inject it into the reagent bottle. At the same time, the picker 112 and the sampler 111 are jointly arranged at the end of the mechanical arm 11, which not only saves space but also facilitates operation.

[0060] Optionally, the picker 112 is configured with an electromagnetic mechanism; the sampler 111 is provided with a syringe 1111, wherein the syringe 1111 is connected to a peristaltic pump via a pipeline 1112 for aspirating and / or injecting water samples.

[0061] Specifically, the interior of the picker 112 is provided with an electromagnetic mechanism (i.e., an electromagnet, not shown in the figure). It should be noted here that the reagent bottle used in conjunction with the electromagnet also needs to be provided with a component (e.g., iron) composed of a material that can be attracted by a magnet. Thus, the reagent bottle can be picked up by the power on and off of the electromagnet. Compared with the traditional method of picking up the reagent bottle by a clamping mechanism (clip), the picker of the electromagnet is safer and will not cause damage to the reagent bottle due to the force of tightening. In addition, by controlling the electromagnetic mechanism, the speed can be increased and the operation can be simplified.

[0062] refer to Figure 7 As shown, the sampler 111 adopts a syringe 1111, and a peristaltic pump (not shown in the figure) is arranged at the other end of the syringe 1111. The syringe 1111 and the peristaltic pump are connected by a pipeline 1112. The water sample can be collected by the action of the peristaltic pump, which replaces manual operation and saves manpower.

[0063] Optionally, refer to Fig. 9 As shown, the processor is connected to the first rotary drive mechanism 14, the second rotary drive mechanism 15, the electromagnetic mechanism and the peristaltic pump respectively. Thus, the processor can control the reagent bottle moving device 1 to rotate horizontally and lift vertically, thereby picking up and moving the reagent bottle, and can also automatically control the collection of water samples. In this way, automation is further achieved in the process of water sample detection.

[0064] Specifically, in actual operation, the processor controls the first rotary drive mechanism 14 to rotate the mechanical arm 11 to the top of the reagent bottle of the reagent rack 2, and then the processor controls the second rotary drive mechanism 15 to lower the mechanical arm 11 to the position of the reagent bottle mouth. Further, the processor controls the electromagnetic mechanism to pick up a reagent bottle. Then, the processor moves the reagent bottle into the mixer 32 by controlling the first rotary drive mechanism 14 and the second rotary drive mechanism 15. Further, the processor controls the peristaltic pump to draw the water sample from the circulation pool 31 using the syringe 1111, and then inject it into the reagent bottle. Then the processor controls the mixer 32 to mix the water sample in the reagent bottle. After completing the mixing operation, the processor moves the reagent bottle into the digester 33 for digestion by controlling the first rotary drive mechanism 14 and the second rotary drive mechanism 15. Finally, under the control of the processor, the reagent bottle containing the water sample is moved to the detector 34 for detection and the detection data is obtained.

[0065] Optionally, a plurality of reagent bottle holes 24 for accommodating reagent bottles are provided on the upper surface of the reagent rack 2, wherein the reagent bottle holes 24 are evenly distributed on a plurality of concentric circles with the center of the reagent rack 2 as the center, and the water sample detection device also includes a third rotation drive mechanism 21 for driving the reagent rack 2 to rotate, and the third rotation drive mechanism 21 is connected to the processor.

[0066] Specifically, refer to Figure 8 and Figure 1 As shown, the surface of the reagent rack 2 is circular, and the reagent bottle holes 24 are evenly distributed on a plurality of concentric circles with the center of the reagent rack 2 as the center. Figure 8 The water sample detection device further includes a third rotation drive mechanism 21 for driving the reagent rack 2 to rotate. The third rotation drive mechanism 21 may be a stepping motor, and the third rotation drive mechanism 21 is connected to the processor (refer to Fig. 9 ). The processor controls the rotation of the stepper motor, thereby controlling the rotation of the reagent rack 2, thereby realizing automatic control of the rotation of the reagent rack, and facilitating the reagent bottle moving device 1 to pick up the reagent bottle from the reagent rack 2.

[0067] Optionally, a plurality of first protrusions 231 are provided on the lower surface of the reagent rack 2, and the plurality of first protrusions 231 are evenly distributed on a first circular track with the center of the reagent rack 2 as the center; a first photoelectric sensor 221 for detecting the first protrusions 231 is also provided below the reagent rack 2, and the first photoelectric sensor 221 is connected to the processor.

[0068] Specifically, refer to Figure 8 As shown, the lower surface of the reagent rack 2 is provided with a plurality of first protrusions 231, and the plurality of first protrusions 231 are evenly distributed on a first circular track with the center of the reagent rack 2 as the center of the circle, and correspond to the reagent bottle holes 24 of the outermost circle (that is, each reagent bottle hole 24 of the outermost circle corresponds to a first protrusion respectively). And the lower part of the reagent rack 2 is also provided with a first photoelectric sensor 221, and the first photoelectric sensor 221 is connected to the processor. In the process of the reagent rack 2 rotating, the first protrusion 231 will pass through the first photoelectric sensor 221, and at the moment when each first protrusion 231 passes through the first photoelectric sensor 221, the first photoelectric sensor 221 will generate a first photoelectric induction pulse signal. At this time, the processor receives and records the number of the first photoelectric induction pulse signals, thereby calculating the angle of rotation of the reagent rack 2 according to the number of the first photoelectric induction pulse signals.

[0069] Optionally, a second protrusion 232 for marking the starting position of rotation is provided on the lower surface of the reagent rack 2, and the second protrusion 232 is provided on a second circular track with the center of the reagent rack 2 as the center; a second photoelectric sensor 222 for detecting the second protrusion 232 is also provided below the reagent rack 2, and the second photoelectric sensor 222 is connected to the processor.

[0070] Specifically, refer to Figure 8 As shown, the lower surface of the reagent rack 2 is provided with a second protrusion 232 for marking the rotation starting position, and the second protrusion 232 is arranged on a second circular track with the center of the reagent rack 2 as the center of the circle. And the lower part of the reagent rack 2 is also provided with a second photoelectric sensor 222, and the second photoelectric sensor 222 is connected with the processor. In the process of the reagent rack 2 rotating, at the moment when the second protrusion 232 passes through the second photoelectric sensor 222, the second photoelectric sensor 222 will produce a second photoelectric induction pulse signal and send it to the processor, and now the processor can receive the second photoelectric induction pulse signal, and the second protrusion is recorded as the starting position of the reagent rack 2 rotation. After determining the starting position, the angle of the reagent rack 2 rotation can be calculated faster by utilizing the first protrusion 231 and the first photoelectric sensor 221 according to the above-mentioned working principle.

[0071] Optionally, the processor is configured to perform the following operations: receiving a photoelectric sensing pulse signal from the second photoelectric sensor 222 ; and switching the rotation angle of the first rotation drive mechanism 14 according to the photoelectric sensing pulse signal received from the second photoelectric sensor 222 .

[0072] Specifically, refer to Fig.10 As shown, the processor is configured to perform the following operations: during the rotation of the reagent rack 2, the processor receives a second photoelectric induction pulse signal from the second photoelectric sensor 222, and then determines that the reagent rack 2 has rotated one circle. In addition, the processor is capable of driving the first rotary drive mechanism 14 to rotate, and when it rotates to the top of the determined reagent bottle. The processor controls the second rotary drive mechanism 15 to drive the robotic arm 11 to descend to the determined position of the reagent bottle to pick up the reagent bottle. In addition, the processor is also configured to switch the rotation angle of the first rotary drive mechanism 14 according to the second photoelectric induction pulse signal, so as to pick up reagent bottles with different circular trajectories on the reagent rack 2. Reference Fig.10 As shown, 241 and 242 are two different circles of reagent bottle holes. For example, when the reagent bottles in the reagent bottle holes of the 241 reagent bottle hole track (for example, the track shown in the figure mark 241) where the mechanical arm is located have been used up (i.e., through the second photoelectric induction pulse signal, it is determined that the reagent rack 2 has rotated one circle), the processor can switch the rotation angle of the first rotary drive mechanism 14, thereby using the first rotary drive mechanism 14 to rotate the mechanical arm 11 to other track positions (i.e., another circle of reagent bottle hole track 242), and then perform the above similar picking operation. Thus, the reagent bottle holes 24 on each circular track of the entire reagent rack 2 can be traversed. In this way, under the action of the processor, the rotation of the reagent rack 2 can be combined with the movement of the reagent bottle moving device 1 to pick up the reagent bottles, and then the automated placement of the reagent bottles can be realized.

[0073] Therefore, according to the technical solution of this embodiment, in the process of detecting water samples, detection can be performed according to fixed steps through a whole set of interrelated equipment. And the detection process is controlled by a processor, which has higher accuracy than manual operation. Thereby, the technical effect of realizing automated operation in the process of water sample detection is achieved. On the premise of ensuring the accuracy of the detection data, time and manpower are saved and work efficiency is improved. This solves the technical problem in the prior art that the water resource detection work efficiency is low because the water sample collection, water sample detection and water sample analysis are all performed by separate devices, and all steps cannot be performed by a set of devices.
