Description

Technical Field

[0001] This utility model relates to the field of groundwater monitoring well technology, specifically a groundwater environment monitoring well. Background Technology

[0002] Groundwater environment monitoring wells are specialized wells used to detect changes in groundwater level, temperature, and quality.

[0003] Chinese utility model patent CN219840633U discloses a groundwater monitoring well, including a vertical shaft with a concrete sleeve inside. A monitoring pipe is installed inside the concrete sleeve. The top of the monitoring pipe is connected to a concrete slab at the shaft opening via a pipe cap bolt, and the bottom is connected to a filter pipe. A water-stop sleeve and a filter sleeve are installed sequentially from top to bottom at the lower end of the concrete sleeve and around the monitoring pipe. This allows the groundwater to be filtered once through the filter sleeve and then filtered a second time through the filter pipe. The filtered groundwater then enters the filter pipe and rises to the monitoring pipe, effectively preventing the monitoring pipe from being blocked by mud and sand in the groundwater. This also helps to reduce construction difficulty and improve construction progress.

[0004] However, impurities such as silt in groundwater can easily adhere to the surface of the filter sleeve and filter pipe, clogging the filter holes and affecting the entry of groundwater into the monitoring pipe, resulting in inaccurate monitoring results and reducing the practicality of the monitoring well.

[0005] Therefore, this utility model provides a groundwater environment monitoring well. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a groundwater environment monitoring well that solves the problems mentioned in the background. This invention allows for the lowering and adjustment of the filter inner cylinder via a handwheel, screw, and screw mechanism, enabling the filter inner cylinder to move out from inside the filter outer cylinder and come into contact with groundwater. This allows groundwater to pass through the filter inner cylinder and enter the monitoring well, facilitating groundwater monitoring, ensuring the accuracy of monitoring results, and demonstrating high practicality.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a groundwater environment monitoring well, including an installation plate, a concrete pipe body fixedly installed at the center of the installation plate, a filter outer cylinder fixedly installed at the bottom end of the concrete pipe body, a filter inner cylinder movably installed inside the concrete pipe body and the filter outer cylinder through an adjustment mechanism, a groove being formed inside the bottom end of the filter inner cylinder, a fixing plate being fixedly installed inside the top end of the concrete pipe body, and a top cover being installed on the top end of the concrete pipe body.

[0008] Furthermore, a limiting mechanism is provided between the top of the filter inner cylinder and the concrete pipe body. The limiting mechanism includes a slider and a groove, and the slider is symmetrically fixed on both sides of the top of the filter inner cylinder.

[0009] Furthermore, the grooves are symmetrically formed on both sides of the inner wall at the bottom end of the concrete pipe, and the slider is limited and slidably installed inside the grooves.

[0010] Furthermore, a screw tube is rotatably installed at the center of the fixed plate, and a handwheel is fixedly installed at the top of the screw tube, which is located inside the concrete pipe.

[0011] Furthermore, a screw is fixedly installed at the center of the inner filter cylinder, and the screw is screwed into the inside of the spiral tube.

[0012] Furthermore, a regular polygonal block is fixedly provided at the top center of the handwheel, and a regular polygonal groove is provided inside the upper cover corresponding to the position of the regular polygonal block, and the regular polygonal block is snapped into the inside of the regular polygonal groove.

[0013] Furthermore, mounting grooves are symmetrically provided inside both ends of the fixing plate, and water quality sensors are symmetrically fixed on both sides of the bottom of the fixing plate, with the water quality sensors located inside the concrete pipe.

[0014] Furthermore, fixing cones are fixedly provided on the four sides of the bottom of the mounting plate. The mounting plate is a concrete disc, and the mounting plate is fixedly installed on the ground by the fixing cones.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a groundwater environment monitoring well where the inner filter cylinder can be lowered and adjusted via a handwheel, screw, and screw rod. This allows the inner filter cylinder to move out from inside the outer filter cylinder, bringing it into contact with groundwater. This allows groundwater to pass through the inner filter cylinder and enter the monitoring well, facilitating groundwater monitoring and ensuring the accuracy of the monitoring results. Furthermore, by adjusting the inner filter cylinder upwards, the bottom of the outer filter cylinder can be used to clean mud and sand from the outer wall of the inner filter cylinder, preventing the monitoring well from being clogged by mud, sand, and other debris. This makes it highly practical. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a groundwater environment monitoring well, including an installation plate 1. A concrete pipe body 2 is fixedly installed at the center of the installation plate 1. A filter outer cylinder 5 is fixedly installed at the bottom end of the concrete pipe body 2. A filter inner cylinder 6 is movably installed inside the concrete pipe body 2 and the filter outer cylinder 5 through an adjustment mechanism. A groove 14 is opened inside the bottom end of the filter inner cylinder 6. A fixing plate 8 is fixedly installed inside the top end of the concrete pipe body 2. A top cover 4 is installed on the top end of the concrete pipe body 2. The filter outer cylinder 5 and the filter inner cylinder 6 can filter mud and other debris in the groundwater, preventing mud and other debris from clogging the monitoring well and the groundwater monitoring. By adjusting the lifting and lowering of the filter inner cylinder 6, mud and other debris on its surface can be cleaned, which can improve the practicality of the monitoring well.

[0023] In this embodiment, a limiting mechanism is provided between the top end of the filter inner cylinder 6 and the concrete pipe body 2. The limiting mechanism includes a slider 12 and a groove 13. The slider 12 is symmetrically fixed on both sides of the top end of the filter inner cylinder 6, and the groove 13 is symmetrically opened on both sides of the inner wall at the bottom end of the concrete pipe body 2. The slider 12 is slidably installed inside the groove 13. The slider 12 and the groove 13 can limit the filter inner cylinder 6, which facilitates the subsequent lifting and lowering adjustment of the filter inner cylinder 6.

[0024] In this embodiment, a screw tube 9 is rotatably mounted at the center of the fixing plate 8. A handwheel 7 is fixedly mounted at the top of the screw tube 9 and is located inside the concrete pipe body 2. A screw rod 10 is fixedly mounted at the center of the inner filter cylinder 6 and is screwed into the inside of the screw tube 9. A regular polygonal block 15 is fixedly mounted at the center of the top of the handwheel 7. A regular polygonal groove is formed inside the upper cover 4 corresponding to the position of the regular polygonal block 15. The regular polygonal block 15 is snapped into the inside of the regular polygonal groove. The fixing plate 8 can support the screw tube 9. The screw tube 9 is rotated by the handwheel 7. The screw connection between the screw tube 9 and the screw rod 10 can drive the inner filter cylinder 6 to descend and adjust inside the monitoring well. The regular polygonal block 15 and the regular polygonal groove can limit the handwheel 7 and prevent the screw rod 9 from rotating on its own.

[0025] In this embodiment, mounting slots are symmetrically provided inside both ends of the fixing plate 8, and water quality sensors 11 are symmetrically fixed on both sides of the bottom of the fixing plate 8. The water quality sensors 11 are installed inside the concrete pipe body 2. The groundwater can be monitored through the water quality sensors 11. The mounting slots facilitate the installation of other sensors, such as water level gauges and water thermometers.

[0026] In this embodiment, the mounting plate 1 is fixedly provided with fixing cones 3 on the four sides of its bottom. The mounting plate 1 is a concrete disc. The mounting plate 1 is fixedly installed on the ground by the fixing cones 3. The mounting plate 1 and the fixing cones 3 can fix the monitoring well and improve the stability of the monitoring well.

[0027] When using this groundwater environmental monitoring well, a hole is drilled at the location where monitoring is required, and the concrete pipe body 2 and the outer filter cylinder 5 are installed inside the hole. Simultaneously, the mounting plate 1 is installed on the ground via a fixing cone 3, which is inserted into the ground. Water quality sensor 11, water level gauge, and water thermometer are installed inside the monitoring well via a mounting groove. The water quality sensor 11 is model SJ-S9. Groundwater is filtered through the outer filter cylinder 5 and the inner filter cylinder 6, allowing it to enter the concrete pipe body 2 for easy access by the water quality sensor 11 and water level gauge. Monitoring instruments such as thermometers and water thermometers are used to monitor groundwater. After a period of use, the top cover 4 is opened and the handwheel 7 is turned. The handwheel 7, through the screw connection between the screw 9 and the screw 10, drives the screw 10 and the inner filter cylinder 6 to descend. The inner filter cylinder 6 slides out from the inside of the outer filter cylinder 5 and comes into contact with the groundwater, facilitating the filtration of groundwater through the inner filter cylinder 6. The inner filter cylinder 6 is repeatedly raised and lowered. The outer filter cylinder 5 can clean the mud and sand on the surface of the inner filter cylinder 6, allowing groundwater to enter the monitoring well through the inner filter cylinder 6, facilitating groundwater monitoring and ensuring the accuracy of the monitoring results.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
