[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 1-4This utility model provides a technical solution for a groundwater quality stratification monitoring device: It includes a base plate 1 and support plates 101 symmetrically installed at both ends of the outer top surface of the base plate 1. A rotating shaft 102 is rotatably installed between the two support plates 101. A wire reel 103 is fixedly sleeved on the outside of the rotating shaft 102, and a wire rope 104 is wound inside the wire reel 103. An opening 105 is provided between the two support plates 101 on the outer top surface of the base plate 1, allowing the wire rope 104 to pass through the opening 105 and extend to the outer bottom surface of the base plate 1, where a connecting block 106 is fixed. Multiple sampling boxes 107 are vertically and equally spaced at the bottom end of the connecting block 106. Adjacent sampling boxes 107 are connected by a spacing adjustment component 2. Water quality sensors 108 are installed on the right outer wall of each sampling box 107. The spacing adjustment component 2 includes a circular sleeve 201 and a sliding rod 2. 02. The outer sidewall of the cylindrical sleeve 201 is provided with limiting holes 203 arranged in a vertical linear array. The sliding rod 202 is inserted into the inner side of the cylinder, and the outer sidewall is provided with a circular hole 204. The inner sidewall of the circular hole 204 is slidably connected to the insertion rod 205. One end of the insertion rod 205 is inserted into the inner sidewall of the limiting hole 203, and the other end is fixedly connected to the inner sidewall of the circular hole 204 through the return spring 206. The opposite ends of the cylinder and the insertion rod 205 are respectively fixed to the corresponding sampling boxes 107. The left outer wall of the three sets of sampling boxes 107 is fixed and connected to the water inlet pipe 3. The outside of the water inlet pipe 3 is fixedly installed with a solenoid valve 301. At the same time, the inlet of the water inlet pipe 3 is fixed with a filter cover 302 by screws. The top of one sampling box 107 is fixed to the connecting block 106, and the bottom of the other sampling box 107 is fixedly connected to the annular counterweight 6.
[0032] In the above embodiment, the insertion rod 205 is first pressed and slid inside the circular hole 204 according to the actual situation, and the return spring 206 is squeezed to make the insertion rod 205 retract into the inside of the cylinder. Then, the slide rod 202 is pulled down to move and adjust the distance between two adjacent sampling boxes 107. After the adjustment is completed, the return spring 206 pushes the insertion rod 205 to be re-inserted into the corresponding limiting hole 203 to limit the insertion rod 205, so that it can obtain the water quality of different water levels as needed, increasing its applicability.
[0033] Then, rotating the rotating shaft 102 drives the wire reel 103 to rotate, unwinding the wire rope 104. This allows the connecting block 106 to carry the sampling box 107 and the water quality sensor 108 into the groundwater, enabling the groundwater flow to contact the water quality sensor 108. The water quality sensor 108 monitors the water quality at different groundwater levels and transmits the monitoring signals to an external processor. The processor can store the monitoring parameters or transmit them to a smart terminal in real time. During the lowering and monitoring process, the gravity of the annular configuration block reduces the tilting of the sampling box 107 and the water quality sensor 108, keeping them vertical. Next, the operator controls the solenoid valve 301 to open the water inlet pipe 3, introducing groundwater at different levels into the corresponding sampling box 107 for sampling and testing. This prevents water sample mixing and further improves monitoring accuracy. The filter cover 302 filters and intercepts impurities in the water, preventing blockage of the water inlet pipe 3.
[0034] The two ends of the rotating shaft 102 extend to the opposite outer walls of the two support plates 101, and the right ends of the outer peripheral surfaces are respectively fixedly installed with a gear 4 and a rotating wheel 401. A semi-circular toothed ring 402 is provided directly above the gear 4. A connecting plate 403 is fixedly installed on the outer wall of one of the support plates 101. A threaded rod 404 is rotatably connected at the center of the outer side of the connecting plate 403. A knob 405 is fixedly installed at the top of the threaded rod 404, and the bottom end passes through the connecting plate 403 and is rotatably connected to the ring. At the same time, guide rods 406 are slidably sleeved at both ends of the inner side of the connecting plate 403. One end of the two guide rods 406 is fixedly connected to the ring.
[0035] In the above embodiment, after the monitoring device reaches the designated position, the turning wheel 401 is stopped, and the knob 405 is turned to drive the threaded rod 404 to rotate. With the assistance of the guide rod 406, the gear ring 402 is driven to move towards the gear 4 and mesh with the gear 4, thereby locking the rotating shaft 102 to prevent it from spinning and thus avoiding affecting the subsequent water quality monitoring work, thereby improving the stability of the device.
[0036] The outer walls of the left and right sides of the base plate 1 are symmetrically provided with square holes 5, and an extension square plate 501 is slidably fitted inside each pair of square holes 5. The opposite ends of the two pairs of extension square plates 501 extend to the outside of the base plate 1 and are respectively fixedly connected to a clamping plate 502. The top of the base plate 1 has symmetrically provided screw holes 503 arranged in a linear array and communicating with the square holes 5 at both ends. The top of the two pairs of extension square plates 501 has a through screw hole 504 arranged in a linear array. The inner sides of screw holes 503 and screw holes 504 are threaded together with a positioning screw 505. According to the size of different monitoring wellheads, the clamping plate 502 is pulled to drive the extension square plate 501 to slide inside the square hole 5, thereby expanding the length of the base plate 1, which makes it easy to adapt to monitoring wellheads of different sizes. Then, the positioning screw 505 is screwed into the inner side of screw hole 504 along screw hole 503, thereby fixing the extension square plate 501, thus increasing the flexibility of the device.
[0037] The working principle of this utility model is as follows: When using it, first adjust the distance between each sampling box 107 according to the actual monitoring needs, then press the insertion rod 205 directly and push or pull the slide rod 202 up or down.
[0038] Meanwhile, the base plate 1 is placed on the monitoring wellhead, and the clamping plate 502 is pushed and pulled to allow the extension square plate 501 to move inside the square hole 5, thereby adjusting the length of the base plate 1.
[0039] Simultaneously, turning the rotating wheel 401 drives the rotating shaft 102 to rotate the wire reel 103, unwinding the wire rope 104 and allowing the sampling box 107 and water quality sensor 108 to enter the groundwater. This allows the groundwater flow to contact the water quality sensor 108, enabling the sensor to monitor the water quality at different groundwater levels. Then, turning the rotating wheel 401 is stopped.
[0040] Next, turning the knob 405 drives the threaded rod 404 to rotate, which drives the gear ring 402 to move towards the gear 4 and mesh with the gear 4 to lock the rotating shaft 102 and prevent it from spinning.
[0041] Finally, the solenoid valve 301 opens the water inlet pipe 3 to introduce groundwater at different water levels into the corresponding sampling box 107 for sampling and testing, avoiding water sample mixing, and cooperating with the water quality sensor 108 to further improve the monitoring accuracy, thereby ensuring the accuracy of the monitoring results.
[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
