[0032] Regarding the specific composition of each module mentioned above, in this embodiment, the water injection module 3 includes a sampling pump controller 301, a two-way valve 302, a sampling pump 303 and a sampling tube 304. The sampling tube 304 is a medical silicone tube, one end of which is connected to the sampling pump 303 through the two-way valve 302, and the other end is a water injection port corresponding to the sample bottle. The sampling pump controller 301 is electrically connected to the inkjet printer controller 802, and it can select the corresponding fixative or water sample with the corresponding information.

[0033] The corresponding profiling fixture 5 is a double-layer structure, which is opened with a profiling hole 6 corresponding to the sample bottle, and each sample bottle is embedded in the profiling hole 6 and clamped by a spring plunger. Furthermore, the bottle cap is designed as an anti-theft cap. A gantry-type stainless steel frame 7 is also fixed on the processing platform 2, and the stainless steel frame 7 is used to fix the dual-axis drive module 41 and the inkjet printer 801. Figure 4 As shown, after the actual product assembly process, the processing platform 2 can be integrally packaged by the external box 1, and movable casters 10 are provided at the four corners of the bottom of the box 1.

[0034] For the realization of automatic locking and coding, such as Figure 2-Figure 3As shown, the dual-axis drive module 41 includes a first servo electric cylinder 411, a fixed plate 412, a first guide rail 413, a first slider 414, a second servo electric cylinder 415, a second guide rail 416 and a second slider 417. The fixed plate 412 is bolted to the stainless steel frame 7. The track direction of the first guide rail 413 is perpendicular to the axial direction of the sample bottle and is slidably connected to the first slider 414. The output end of the first servo electric cylinder 411 is connected and fixed to the first slider 414.

The two clamps 425 are electromagnetically relatively slidable and are turned on and off by the solenoid valve 422.

[0036] In the actual water quality sampling process, it is implemented according to the following steps:

[0037] 1. The water filling station is fixed above the sample bottle. When a sample bottle is finished filling, the motor will drive the sample assembly to rotate so that the next empty bottle is placed below the water filling station. The sampling pump 303 is connected to the water filling station. The water filling station is provided with a two-way connection. The sampling tube 304 is connected to the two-way connection so that the sampling pump 303 draws water into the sampling tube 304, and the sampling tube 304 flows into the water filling station, and the water filling station then fills the sample bottle with water. The sampling tube 304 has an automatic flushing function to avoid inaccurate sampling results. The sampling tube 304 is a high-strength medical silicone tube, and the pump body is a reinforced engineering plastic quick disassembly module combination. The corresponding motor shaft and pump tube bracket are made of stainless steel.

[0038] 2. The sample bottle is placed in the profiling fixture 5, and the bottle body is clamped by the spring plunger to prevent the position of the sample bottle from shifting during the rotation process, resulting in failure to inject water into the sample bottle. After the water injection is completed, the corresponding fixative is automatically added according to the on-site excessive factor of the water sample, including hydrochloric acid, sulfuric acid and sodium hydroxide solution, to ensure the representativeness of the sample;

[0039] 3. The bottle cap of the sample bottle is designed to prevent theft. The rotating electric clamp 42 is used to automatically screw the bottle cap on the bottle mouth, and fully realize automatic assembly. The bottle cap is designed to prevent theft. When the sample bottle is opened manually, the anti-theft ring will fall off the bottle body and cannot be restored. The rotating electric clamp 42 is provided with a two-axis drive module to complete the tightening of the cap on the sample bottle;

[0040] 4. The bottle caps are clamped and placed by rotating the two groups of clamping jaws 425 in the electric clamping jaws 42. The internal electromagnetic valve 422 is turned on and off to realize the displacement of the two magnetically attracted clamping jaws 425 in the slide groove 424. After being relatively close to each other, the corresponding bottle caps are clamped. Then, the driving body 421 is driven to rotate, and the telescopic block 423 is driven to perform a threading action as a whole, and the bottle caps on the bottle cap placement plate and the tightening threads on the top of the sample bottle are automatically tightened.

[0041] 5. Use the inkjet printer 801 and blockchain technology simultaneously to automatically add labels and seal the water sample bottles when retaining samples to prevent the water samples from being replaced. Encode the required information, including sampling time and sample number, over-standard factors and concentration, etc. The coding is performed after the sample bottle is assembled. It can be set to be sprayed after sampling is completed, or it can be set to be sprayed after each sampling.

[0042] 6. When the measuring instrument is used together, the analysis equipment can be remotely controlled to realize remote sample retention for the detected abnormal situation, thereby solidifying the evidence. The information of exceeding the standard and sample retention is automatically uploaded to the blockchain network, and notifications are sent to the quality control platform and mobile phone App at the same time. The relevant data is uploaded to the quality control platform to leave a record. After the sample retention is completed, a notification will be sent to the operator to remind him to take away the sample bottle and place a new sample bottle and bottle cap.

[0043] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
