Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and more specifically, to a monitoring and early warning device for perfluorinated compounds in groundwater. Background Technology

[0002] Since their introduction in the 1940s, perfluorinated compounds (PFAS) have been widely used in textiles, fire protection, electronics and other fields due to their unique physicochemical properties. However, with the continuous increase in usage, the negative environmental impact of PFAS has gradually become apparent. Due to their stable chemical structure, they are difficult to degrade in the natural environment. Through atmospheric deposition, surface runoff and other pathways, large amounts of PFAS seep into groundwater, causing varying degrees of pollution to groundwater in many parts of the world. In the face of the increasingly serious problem of PFAS pollution in groundwater, the development of new monitoring and early warning devices is urgently needed.

[0003] A search revealed that Chinese patent CN116698565A discloses "an online sampling and enrichment device and method for perfluorinated compounds in groundwater. The enrichment device includes a first container for storing and measuring groundwater, with a collection device connected to the first container for collecting groundwater; an enrichment device for adsorbing compounds in the groundwater and discharging wastewater, connected to the collection device; a second container for transferring and draining the wastewater discharged from the enrichment device, connected to the enrichment device; and a vacuum pump connected to the second container to control the flow rate of groundwater from the collection device into the enrichment device by changing the pressure inside the second container. This technical solution solves the technical problem of high sample preservation and transportation costs in the detection and analysis of perfluorinated compounds in the prior art. This technical solution achieves in-situ enrichment of perfluorinated compounds in groundwater, greatly reducing sample volume and sample transportation costs." However, the following defects still exist:

[0004] (1) In actual use, the equipment only focuses on the in-situ enrichment of perfluorinated compounds in groundwater and does not involve the real-time monitoring of key indicators such as the concentration of perfluorinated compounds in groundwater. It cannot directly obtain the specific content data of pollutants in the water and is difficult to meet the actual needs of dynamically grasping the groundwater pollution status.

[0005] (2) In actual use, the equipment lacks an alarm mechanism for changes in the concentration of perfluorinated compounds in groundwater. When the pollutant concentration exceeds the safety threshold or abnormal fluctuations occur, it cannot issue a warning signal in a timely manner, making it difficult for relevant personnel to detect pollution changes and take countermeasures in a timely manner, which poses a risk of delayed pollution prevention and control. Therefore, a groundwater perfluorinated compound monitoring and early warning device is proposed. Utility Model Content

Magnet 207 and second magnet 209 are magnetically connected to each other. A display screen 210 is fixedly installed on one side of the body 1. The display screen 210 is electrically connected to the water quality sensor 208. In use, the first motor 203 drives the winding reel 204 to rotate inside the protective shell 202 of the fixed shell 201 on one side of the body 1, which can retract and extend the detection tube 205. The float 206 enables the water quality sensor 208 at the end of the detection tube 205 to float on the water surface, ensuring a stable detection position. The water quality sensor 208 is magnetically connected to the first magnet 207 at the end of the detection tube 205 through the second magnet 209, which is convenient for installation and replacement.

The rotating column 7 rotates on one side of the rotating block 6, and in conjunction with the second motor 10, drives the second support rod 11 to rotate, so that the rain cover 12 between the first support rod 8 and the second support rod 11 can be unfolded or retracted. The unfolded rain cover 12 not only blocks rainwater, but also blocks direct sunlight, avoiding damage to the internal components of the machine body 1 due to high temperature caused by prolonged exposure to strong light; at the same time, it can block dust, fallen leaves and other debris, reducing the pollution and interference of external impurities on the equipment, and ensuring the stable operation of the device in complex outdoor environments.

[0033] like Figure 4As shown, an ultrasonic sensor 13, model AML913, is fixedly installed on one side of the body 1. The ultrasonic sensor 13 is electrically connected to the display screen 210. An ultrasonic transmitter 14 is fixedly installed on the bottom of the ultrasonic sensor 13. In use, the ultrasonic sensor 13 on one side of the body 1 emits ultrasonic waves through the ultrasonic transmitter 14 at the bottom, which can detect the water level depth of groundwater. The detection data is transmitted to the display screen 210 and, together with the data from the water quality sensor 208, comprehensively reflects the condition of groundwater and provides more reference information for monitoring work.

When in use, the indicator light 15 at the bottom of the water quality sensor 208 lights up during detection, indicating that the sensor is in working condition. The internal counterweight 16 can adjust the center of gravity of the sensor to ensure that it maintains a stable detection posture in the water and improves the accuracy of the detection data.

A storage box 19 is fixedly installed on the top of the sliders 18. A pull handle 20 is fixedly installed on the side of the storage box 19 away from the body 1. In use, the storage box 19 in the storage slot 17 on one side of the body 1 can be flexibly pulled out by the sliders 18. Pulling the handle 20 makes it easy to operate. The storage box 19 can be used to store tools, spare sensors and other items for testing, so that operators can easily access them and improve the convenience of monitoring work.

The third magnet 23 and the fourth magnet 24 are magnetically connected to each other. In use, the casters 21 and the sliding handle 22 at the bottom of the body 1 facilitate the movement of the device and can be adjusted according to monitoring needs. The sliding handle 22 is magnetically connected to the fourth magnet 24 on one side of the body 1 through the third magnet 23, which can fix the handle when the device is not moved, avoid shaking, and save space.

[0037] Specifically, when using the local groundwater perfluorinated compound monitoring and early warning device: Inside the protective shell 202 of the fixed shell 201 on one side of the main body 1, the first motor 203 drives the winding reel 204 to rotate, which can retract and extend the detection tube 205. The float 206 allows the water quality sensor 208 at the end of the detection tube 205 to float on the water surface, ensuring a stable detection position. The water quality sensor 208 is magnetically connected to the first magnet 207 at the end of the detection tube 205 via the second magnet 209, facilitating installation and replacement. The perfluorinated compound data detected by the water quality sensor 208 is transmitted to the display screen 210, allowing operators to visually view the groundwater pollution situation and achieve real-time monitoring of groundwater quality (e.g., Figure 2 , Figure 3 and Figure 4 As shown), the sliding block 302 on the top fixing post 301 of the fixed housing 201 provides the mounting base for the alarm 303. When the water quality sensor 208 detects that the perfluorinated compound content exceeds the standard, it will transmit a signal to the controller 305. The controller 305 triggers the alarm 303 and the alarm light 306 to work. The alarm 303 amplifies the alarm sound through the surrounding sound amplification slot 304, and the alarm light 306 lights up, providing a warning from both sound and visual aspects, reminding relevant personnel to take timely measures (such as...). Figure 3 and Figure 5 (As shown).

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
