Description

Technical Field

[0001] This utility model relates to the field of water source monitoring technology, specifically a groundwater pollution monitoring device. Background Technology

[0002] Groundwater pollution is a phenomenon caused by human factors that deteriorate the quality of groundwater. The main causes of groundwater pollution include: direct discharge of industrial wastewater into the ground, intrusion of polluted surface water into underground aquifers, and seepage of water contaminated by human and animal excrement or excessive use of pesticides into the ground. As a result of pollution, the content of harmful components in groundwater such as phenols, chromium, mercury, arsenic, radioactive substances, bacteria, and organic matter increases. Polluted groundwater is harmful to human health and industrial and agricultural production. Currently, groundwater pollution monitoring devices are often used when preventing and controlling groundwater pollution.

[0003] When monitoring groundwater pollution, the device needs to be moved by cable when placed in or removed from the groundwater monitoring well. Due to the narrow internal space of the groundwater monitoring well, the cable will shake when the device is pulled, causing the outer side of the device to collide with the inner wall of the well, resulting in wear and tear on the device. Furthermore, existing technology cannot protect the sensing area of ​​the device, allowing large foreign objects to adhere to the sensing area and affecting the monitoring data.

[0004] To address the aforementioned issues, a groundwater pollution monitoring device is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1-4This utility model discloses a groundwater pollution monitoring device, comprising a mounting base 1, to which a monitoring device body 2 is fixedly connected for water quality monitoring. A filter screen 3 is fitted over the monitoring device body 2, protecting and filtering the sensing area of ​​the monitoring device body 2. Connecting posts 4 are fixedly connected to both sides of the top of the filter screen 3, and insertion holes 5 are provided on the outer sides of the two connecting posts 4, allowing for easy installation and removal of the filter screen 3 with the help of insertion posts 10. Through holes 6 are provided on both sides of the top of the mounting base 1, allowing the connecting posts 4 to pass through. Disassembly components are connected to both sides of the top of the mounting base 1, and these components are located outside the through holes 6. A mounting ring 13 is fitted over the filter screen 3, securing four buffer seats 14. Four buffer seats 14 are fixedly connected to the bottom of the mounting ring 13, and each of the four buffer seats 14 has a sliding groove 15 on its outer side. Two sliders 16 are slidably connected within the sliding groove 15, allowing the sliders 16 to slide within the groove 15. Each of the two sliders 16 is rotatably connected to a movable rod 17 on one adjacent side, which serves as a connection. Each of the two movable rods 17 is rotatably connected to a protective plate 18 at one adjacent end. The protective plate 18 is arc-shaped to improve the protective effect. Four limiting components are connected to the outside of the mounting ring 13, and four flexible spring pieces 27 are fixedly connected to the outside of the mounting base 1. The flexible spring pieces 27 are made of metal and have strong stability, ensuring the stability of the mounting ring 13. Spring dampers 19 are provided on opposite sides of the two sliders 16, and the spring dampers 19 are located within the slide groove 15, serving as shock absorbers and buffers. A connecting rod 24 is fixedly connected to the top of the mounting base 1, and a float 25 is fixedly connected to the top of the connecting rod 24. A cable 26 passes through and is fixedly connected to the float 25, and the bottom of the cable 26 is electrically connected to the monitoring device body 2. The flexible spring 27 corresponds to the limiting component, and a pressing block 28 is fixedly connected to the outer end of the flexible spring 27. The pressing block 28 can deform the flexible spring 27, making it easy to remove the flexible spring 27 from the slot 21.

[0033] Reference Figure 2 and Figure 4 The disassembly assembly includes a fixing post 7, the bottom of which is fixedly connected to the mounting base 1. A telescopic groove 8 is provided inside the fixing post 7, and a spring 9 is fixedly connected inside the telescopic groove 8. An insert post 10 is fixedly connected to one end of the spring 9. The insert post 10 is located inside the telescopic groove 8, and its exterior is slidably connected to the inner wall of the telescopic groove 8. A guide groove 11 is provided through the top of the fixing post 7, and a push block 12 is slidably connected through the guide groove 11. The bottom of the push block 12 is fixedly connected to the insert post 10. The disassembly assembly can easily drive the insert post 10 to extend and retract within the telescopic groove 8, thereby controlling the insertion or removal of the insert post 10 from the insertion hole 5, thus realizing the installation and disassembly of the filter screen cover 3.

[0034] Reference Figure 3 The limiting component includes a mounting block 20, the inner side of which is fixedly connected to the outer side of the mounting ring 13. The top of the mounting block 20 has a slot 21, and the outer side of the mounting block 20 has a groove 22, which communicates with the slot 21. A limiting block 23 is fixedly connected inside the slot 21, and the limiting block 23 is located on both sides of the groove 22. The limiting component can limit the flexible spring sheet 27 on the outer side of the mounting base 1, thereby facilitating the installation and removal of the mounting ring 13.

[0035] Working principle: When monitoring a water source, the monitoring device body 2 is placed into the well to be monitored via cable 26. When the protective plate 18 is impacted, the external force acting on the protective plate 18 causes the slider 16 to slide within the groove 15 via the movable rod 17. The spring damper 19 on the opposite side of the slider 16 acts as a buffer, reducing the shaking of the protective plate 18 and protecting the monitoring device body 2. When the protective plate 18 needs to be installed, the four mounting blocks 20 on the outside of the mounting ring 13 are aligned with the four flexible spring pieces 27 on the outside of the mounting base 1, so that the flexible spring pieces 27 are inserted into the slots 21 in the mounting blocks 20. At this time, the U-shaped flexible spring pieces 27 are compressed by the limiting block 23 and the pressing block 28 enters the slot 22. After the flexible spring 27 is fully inserted into the slot 21, the flexible spring 27 is released from the pressure of the limiting block 23 and thus resets, opening up in the slot 21. The limiting block 23 limits the flexible spring 27, completing the installation of the mounting ring 13 and the protective plate 18. The filter screen 3 can protect and filter the sensing area of ​​the monitoring device body 2, preventing large foreign objects from adhering to the sensing area of ​​the monitoring device body 2 and affecting the monitoring data. When the filter screen 3 needs to be disassembled, push the two push blocks 12 outward. The push blocks 12 drive the insert post 10 to compress the spring 9 and enter the telescopic groove 8. At this time, the insert post 10 is pulled out from the insertion hole 5 on the outside of the connecting post 4, making it convenient for the connecting post 4 to pass through the through hole 6, thus completing the disassembly of the filter screen 3.
