[0002] The high-pressure automatic cleaning device for automatic water samplers is an auxiliary device used in automatic water samplers. It uses high-pressure water flow to automatically clean the sampling bottles, pipelines and other components of the sampler to ensure the cleanliness of the sampling equipment, prevent cross-contamination between different water samples, and ensure the accuracy and reliability of the sampling data.

[0003] Currently, the cleaning process of sample holders is often done manually, which can easily lead to residual impurities in the sample bottle, making the sample susceptible to cross-contamination and resulting in distorted test results.

[0004] Therefore, a high-pressure automatic cleaning device for automatic water samplers is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure automatic cleaning device for an automatic water sampler, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure automatic cleaning device for an automatic water sampler, comprising a sampler, wherein the sampler has a door on its front side; A sample retention unit is placed inside a sample retainer. The sample retention unit includes a sample retention bottle, a sample addition component, and a sample discharge component. The sample addition component is used to add a sample into the sample retention bottle, and the sample discharge component is used to discharge the sample from the sample retention bottle. A cleaning unit is located outside the sample retention unit. The cleaning unit includes a cleaning component and a collection component. The cleaning component is used to clean the sample retention bottle, and the collection component is used to collect the wastewater generated during the cleaning of the sample retention bottle. With the cooperation of the sample retention unit and the cleaning unit, automatic water quality sampling and automatic cleaning can be achieved.

[0007] Preferably, the sample dispensing assembly includes a constant temperature fan box, a support is provided below the constant temperature fan box, a sample dispensing tube is connected inside the support, and a sample dispensing head is connected to the end of the sample dispensing tube.

[0008] Preferably, the sampling assembly includes a sample bottle, the bottom of which is provided with an electromagnetic discharge valve, a wire harness is connected to the outer wall of the electromagnetic discharge valve, and a power supply device is connected to the end of the wire harness away from the electromagnetic discharge valve.

[0009] Preferably, the end of the support is connected to the inner wall of the sample holder, and the sample dispensing head is arranged parallel to the sample bottle. With the support of the support, the sample dispensing head can stably add samples into the sample bottle.

[0010] Preferably, the cleaning assembly includes a frame, a motor is connected to one end of the frame, a rotating rod is connected to the output end of the motor, a rotating frame is connected to the end of the rotating rod, a water-air dual-purpose pump is provided above the rotating frame, a delivery pipe is connected to the bottom of the water-air dual-purpose pump, and a nozzle is connected to the end of the delivery pipe away from the water-air dual-purpose pump.

[0011] Preferably, the collection component includes a fixing frame, a screw is sleeved inside the fixing frame, a receiving hopper is sleeved on the outer wall of the screw, a collecting pipe is connected to the bottom of the receiving hopper, and a wastewater collection tank is connected to the end of the collecting pipe away from the receiving hopper.

[0012] Preferably, the outer wall of the rotating frame is rotatably connected to the inside of the receiving hopper, and the bottom of the rotating frame is connected to the top surface of the power supply equipment. The rotating frame can drive the sample dispensing assembly to rotate inside the receiving hopper to transport the sample bottle downwards to the nozzle.

[0013] Preferably, the end of the frame furthest from the motor is connected to the inside of the receiving bucket, and the outer wall of the motor is a waterproof shell to prevent water entering the receiving bucket from damaging the motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The high-pressure automatic cleaning device for the automatic water sampler consists of a sample retention unit. When water samples are retained, the sample retention mechanism adds the sample into the sample bottle through the sample addition tube and sample addition head. Under the control of the constant temperature fan box, the internal temperature of the sampler can be kept constant. After the sample retention is completed, the sample bottle needs to be cleaned. At this time, the power supply equipment opens the electromagnetic valve through the wiring harness to discharge the sample inside the sample bottle, which can then cooperate with the cleaning unit to clean the sample bottle. 2. The high-pressure automatic cleaning device of this automatic water sampler consists of a cleaning unit. When cleaning the sample bottle, the discharge assembly discharges water from inside the bottle. At this time, the water-air dual-purpose pump starts working, supplying water to the nozzle through the delivery pipe. The nozzle sprays water onto the sample bottle for cleaning. The high-pressure water jet is sprayed through the rotating nozzle, thoroughly rinsing the inner wall and bottom of the bottle. The nozzle has nozzles distributed circumferentially around its center. After the sample bottle is cleaned, the discharge assembly transports the wastewater into the receiving hopper and then into the wastewater collection tank through the manifold. After the sample bottle is washed, the water-air dual-purpose pump stops supplying water to the delivery pipe and instead supplies air to the delivery pipe and nozzle. The airflow dries any remaining water droplets on the inner wall of the sample bottle. The system controls the timing and pressure of the air jet to ensure the bottle reaches the required dryness standard. Once the set drying time is reached, the air-washing nozzle valve is closed, stopping the air jet and completing the drying process. At this point, the motor is started, and the rotating rod fixedly installed at its output end rotates accordingly. The rotating rod drives the rotating frame and the sample bottle nested inside the frame to rotate, moving another sample bottle under the nozzle for cleaning. This structure avoids the remnants of algae, silt, oil, or high-concentration pollutants adhering to the sample bottle, which could lead to secondary contamination of subsequent samples and distorted test results. Furthermore, this structure enables automatic cleaning after sampling without manual intervention. The cleaning process is fully automated, requiring no disassembly of components, reducing the frequency of manual intervention, and is particularly suitable for remote, multi-site unattended scenarios.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a high-pressure automatic cleaning device for an automatic water sampler, including a sampler 1, and a door is provided on the front of the sampler 1. The sample retention unit 2 is placed inside the sample retainer 1. The sample retention unit 2 includes a sample retention bottle 25, a sample addition component, and a sample discharge component. The sample addition component is used to add a sample into the sample retention bottle 25, and the sample discharge component is used to discharge the sample into the sample retention bottle 25. The cleaning unit 3 is located outside the sample retention unit 2. The cleaning unit 3 includes a cleaning component and a collection component. The cleaning component is used to clean the sample retention bottle 25, and the collection component is used to collect the wastewater generated from cleaning the sample retention bottle 25.

[0024] When in use, with the cooperation of the sample retention unit 2 and the cleaning unit 3, water quality can be automatically sampled and then automatically cleaned.

[0025] Example 2 Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows: The sample addition assembly includes a constant temperature fan box 21, a support 22 is provided below the constant temperature fan box 21, a sample addition tube 23 is connected inside the support 22, and a sample addition head 24 is connected to the end of the sample addition tube 23. The sample discharge assembly includes a sample retention bottle 25, an electromagnetic discharge valve 26 is provided at the bottom of the sample retention bottle 25, a wire harness 27 is connected to the outer wall of the electromagnetic discharge valve 26, and a power supply device 28 is connected to the end of the wire harness 27 away from the electromagnetic discharge valve 26.

[0026] The end of the support 22 is connected to the inner wall of the sample holder 1, and the sample dispensing head 24 is set parallel to the sample bottle 25. With the support of the support 22, the sample dispensing head 24 stably adds the sample into the sample bottle 25.

[0027] When using the sample holder, the sample holder adds the sample into the sample bottle 25 through the sample tube 23 and the sample head 24. Under the control of the constant temperature fan box 21, the internal temperature of the sample holder 1 can be kept constant. After the sample is collected, the sample bottle 25 needs to be cleaned. At this time, the power supply device 28 opens the electromagnetic valve 26 through the wiring harness 27 to discharge the sample from the sample bottle 25, which can then be used in conjunction with the cleaning unit 3 to clean the sample bottle 25.

[0028] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The cleaning assembly includes a frame 39, with a motor 310 connected to one end of the frame 39. A rotating rod 311 is connected to the output end of the motor 310, and a rotating frame 312 is connected to the end of the rotating rod 311. A water-air dual-purpose pump 31 is installed above the rotating frame 312. A delivery pipe 32 is connected to the bottom of the water-air dual-purpose pump 31, and a nozzle 33 is connected to the end of the delivery pipe 32 away from the water-air dual-purpose pump 31. The collection assembly includes a fixed frame 34, with a screw 35 sleeved inside the fixed frame 34. A receiving hopper 36 is sleeved on the outer wall of the screw 35. A collecting pipe 37 is connected to the bottom of the receiving hopper 36, and a wastewater collection tank 38 is connected to the end of the collecting pipe 37 away from the receiving hopper 36.

[0029] The outer wall of the rotating frame 312 is rotatably connected to the inside of the receiving hopper 36, and the bottom of the rotating frame 312 is connected to the top surface of the power supply equipment 28. The rotating frame 312 can drive the sample dispensing component to rotate inside the receiving hopper 36 to transport the sample bottle 25 to the bottom of the nozzle 33.

[0030] The end of the frame 39 furthest from the motor 310 is connected to the inside of the receiving bucket 36. The outer wall of the motor 310 is a waterproof shell to prevent water from entering the receiving bucket 36 and damaging the motor 310.

[0031] During use, when cleaning the sample bottle 25, the discharge assembly drains the water from inside the bottle. At this time, the water-air dual-purpose pump 31 starts working, supplying water to the nozzle 33 through the delivery pipe 32. The nozzle 33 sprays water onto the sample bottle 25 for cleaning. The high-pressure water jet is sprayed through the rotating nozzle 33, thoroughly rinsing the inner wall and bottom of the bottle. The nozzle 33 has nozzles on its outer wall, distributed circumferentially around its center. After the sample bottle 25 is cleaned, the discharge assembly transports the wastewater into the receiving hopper 36 and then into the wastewater collection tank 38 through the manifold 37. After the sample bottle 25 is completely washed, the water-air dual-purpose pump 31 stops supplying water to the delivery pipe 32 and instead supplies air to the delivery pipe 32 and the nozzle 33. The airflow can dry any remaining water droplets on the inner wall of the sample bottle 25. The timing and pressure of the air are controlled to ensure that the bottle reaches the dryness standard. After the set drying time is reached, the air washing nozzle valve is closed, the air jet stops, and the drying process is completed. At this time, the motor 310 is started, and the rotating rod 311 fixedly installed at its output end rotates accordingly. The rotating rod 311 drives the rotating frame 312 and the sample bottle 25 nested inside the rotating frame 312 to rotate, rotating another sample bottle 25 to below the nozzle 33 for cleaning treatment of the sample bottle 25. This structure can avoid the residual algae, mud, oil or high concentration of pollutants attached to the inside of the sample bottle 25, which will cause secondary contamination of subsequent samples and result in distorted test results. Moreover, this structure can automatically trigger cleaning after sampling without manual intervention. The cleaning process is fully automatic, without the need to disassemble parts, reducing the frequency of manual operation. It is especially suitable for remote, multi-site unattended scenarios.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
