Description

Technical Field

[0001] This utility model belongs to the technical field of hydrological monitoring equipment, specifically relating to a hydrogeological monitoring device. Background Technology

[0002] Hydrogeological monitoring is a crucial foundational task in the fields of environmental science and geological engineering. Its main task is to conduct long-term, stable, and systematic collection and analysis of groundwater and soil samples at different depths and in different areas through the deployment of monitoring devices. This results in continuous and reliable hydrogeological data, which is essential for groundwater resource surveys, pollution source tracing and remediation, and mineral resource exploration. It is also necessary for geological disaster risk assessment and early warning, rational allocation of regional water resources, site selection for major engineering projects, and foundation stability analysis. Currently, most hydrogeological monitoring methods rely on borehole sampling or fixed observation wells. While these methods can obtain groundwater or soil information to some extent, they are often complex to operate, time-consuming, and lack flexibility in adjusting sampling depth and location. This makes it difficult to meet the needs of efficient monitoring under various scenarios and conditions. Especially against the backdrop of rapid urbanization and increasingly severe climate change, groundwater environmental problems are frequent, and the risk of geological disasters is increasing. The role of hydrogeological monitoring in disaster prevention and mitigation, ecological environmental protection, and sustainable resource utilization is becoming increasingly prominent. Therefore, improving monitoring equipment is particularly important.

[0003] However, existing hydrogeological monitoring devices still have many shortcomings: First, most devices have a relatively simple sampling function, which can only perform fixed-point sampling at a single depth and cannot obtain comparative samples from multiple depths in a single deployment, resulting in low sampling efficiency and insufficient data comprehensiveness. Second, the equipment has poor adaptability and is difficult to flexibly adapt to the monitoring needs of different strata hardness or depths. Manually adjusting the depth is not only laborious but also inaccurate. Finally, existing devices are not convenient to operate in complex geological environments, require frequent maintenance and are labor-intensive, which limits the implementation of efficient monitoring work. Therefore, this utility model provides a hydrogeological monitoring device to solve the problems of single sampling function, insufficient equipment adaptability, high production cost and low operation and maintenance efficiency in the existing technology. Utility Model Content

[0004] In view of this, this utility model proposes a hydrogeological monitoring device, which is applied to the field of hydrological monitoring equipment technology, and solves the existing technical problems of single sampling function, poor equipment adaptability, high production cost and reduced production efficiency.

[0005] To achieve the above-mentioned technical objectives, the specific technical solution adopted by this utility model is as follows: A hydrogeological monitoring device includes a limiting plate, a limiting sleeve fixedly connected inside the limiting plate, a support screw rotatably connected inside the limiting sleeve, a bottom support rod fixedly connected to one end of the support screw, a movable platform located below the limiting plate threadedly connected to the outer side of the support screw, a heating plate fixedly connected to the bottom of the movable platform and to one side of the support screw, a side mounting plate fixedly connected to one side of the movable platform, a collection tank fixedly connected inside the side mounting plate, an installation pipe extending into the heating plate fixedly connected to the bottom of the collection tank, a water outlet valve fixedly connected to the bottom of the heating plate, and a side of the movable platform... The device is rotatably connected to a swing arm, with a second drive motor fixedly connected to the top of each swing arm at equal intervals. Sampling tubes, each designed for use with a corresponding second drive motor, are fixedly connected to the bottom of each swing arm. Each sampling tube contains a sampling spiral conveyor rod, and a sealing plug is installed at the bottom of each tube. The output end of each second drive motor is connected to the corresponding sampling spiral conveyor rod. In use, the sealing plug at the bottom of the sampling tube is removed, and the second drive motor rotates, driving the corresponding sampling spiral conveyor rod to assist in on-site sampling. Multiple samples can be taken on-site, improving the comprehensiveness of subsequent testing.

[0006] Furthermore, a first drive motor located on one side of the limiting sleeve is fixedly connected to the top of the limiting plate. A first gear is fixedly connected to the output end of the first drive motor. A second gear is fixedly connected to the outside of the support screw and located on the top of the limiting sleeve. The second gear meshes with the first gear. When the first drive motor runs, it drives the first gear to rotate, which in turn drives the second gear meshing on one side to rotate, thereby driving the support screw to rotate as a whole, thus achieving the height adjustment required for the moving platform and meeting different height operation scenarios. The moving platform is equipped with internal support rods that are evenly distributed and extend into the heating plate. The moving platform and the heating plate are reinforced and connected by multiple internal support rods. Heating plates are fixedly connected inside the heating plate and around the installation pipe for heating the transported water. A third drive motor is fixedly connected inside the moving platform. The output end of the third drive motor is fixedly connected to the swing rod. The side of the swing rod away from the third drive motor is rotatably connected to the inside of the moving platform through a connecting shaft. The moving platform has a limiting cavity that cooperates with the rotation of the swing rod. By opening a limiting cavity inside the moving platform to limit the installation of the third drive motor and the swing rod, the angle adjustment is ensured.

[0007] Furthermore, a pipe fixing seat is installed at the top end of the support screw, and a top mounting plate is fixedly connected to the top of the pipe fixing seat.

[0008] Furthermore, a cleaning water storage tank is fixedly connected to the top of the top mounting plate, and a water outlet pipe that runs through the top mounting plate is fixedly connected to the bottom of the cleaning water storage tank. A valve is fixedly connected to the outside of the water outlet pipe, and one end of the water outlet pipe extends into the inside of the pipe fixing seat. The inside of the pipe fixing seat has a storage cavity to accommodate the water outlet pipe, which facilitates the storage of the water outlet pipe when not in operation, improving the aesthetics of the equipment. At the same time, it is convenient to open the valve to deliver the water stored in the cleaning water storage tank, which facilitates local cleaning of the monitored site, thereby improving the flexibility of the equipment. A wireless signal transceiver is fixedly connected to the top of the top mounting plate and to one side of the cleaning water storage tank. A main control board is fixedly connected inside the wireless signal transceiver, and a control chip is fixedly connected to the outside of the main control board. The first drive motor, the second drive motor, the wireless signal transceiver, the valve, the heating plate, the water outlet valve, and the third drive motor are all electrically connected to the control chip. The control chip is used to control the operation of the first drive motor, the second drive motor, the wireless signal transceiver, the valve, the heating plate, the water outlet valve, and the third drive motor, realizing unified management of electrical equipment.

[0009] Furthermore, a support base is fixedly connected to the bottom of the bottom support rod. The support base has equidistantly distributed mounting slots inside, and each mounting slot is threaded with a positioning bolt extending to the bottom of the support base. The mounting slots and positioning bolts work together to facilitate the positioning of the entire equipment and the monitoring work site, thereby improving the overall stability of the equipment during operation.

[0010] Furthermore, a positioning frame is installed at the bottom of the pipe fixing seat. The bottom of the positioning frame is connected to the top of the limiting plate. The positioning frame installed between the pipe fixing seat and the support screw plays an auxiliary limiting role.

[0011] By adopting the above technical solution, this utility model can also bring the following beneficial effects: 1. This utility model discloses a hydrogeological monitoring device. By setting a limiting plate at the bottom of the device, a top mounting plate, and a bottom support rod, and using positioning bolts at the bottom of the support base to drill into the ground, it can achieve rapid fixation in various geological environments. This fixing method not only avoids the instability problem of traditional devices relying on manual weight-bearing or temporary support, but also maintains the stability and verticality of the device under long-term monitoring operations or external interference such as strong winds and vibrations, preventing tilting, displacement, or loosening during the sampling process. This ensures accurate sample collection location and reliable data. At the same time, this structure simplifies the on-site installation process, and deployment can be completed without additional auxiliary tools. It has the advantages of improving overall stability, enhancing environmental adaptability, and reducing the difficulty of manual operation.

This process avoids the errors and laboriousness of manual adjustment, not only improving the flexibility and accuracy of sampling depth adjustment, but also allowing flexible adjustment according to different stratum hardness or depth requirements. It has the advantages of accurate depth adjustment, reliable positioning and convenient operation.

[0013] 3. This utility model discloses a hydrogeological monitoring device. A third drive motor rotates a swing arm, allowing multiple sampling tubes to flexibly adjust their sampling orientation within a certain angle range, covering sampling points in different locations. After removing the sealing plug, a second drive motor rotates a sampling spiral conveyor rod, cutting and lifting the target soil or groundwater sample into the sampling tube. This enables simultaneous multi-point, multi-depth sampling in a single deployment, significantly improving the comprehensiveness and efficiency of sampling. Simultaneously, the device is equipped with a water outlet pipe and replaceable hose, allowing for the discharge of cleaning water from the storage tank for rapid flushing and cleaning of the site, ensuring a clean working environment and reducing subsequent maintenance workload.

[0024] The movable platform 4 is equipped with internal support rods 41 that are evenly distributed and extend into the heating plate 45.

The control chip is used to control the first drive motor 11, the second drive motor 15, the wireless signal transceiver 22, the valve 25, and the heating plate 45. The operation of the outlet valve 46 and the third drive motor 47 enables unified management of the power equipment. The entire workflow is centrally controlled and monitored by the control chip through the wireless signal transceiver 22. Staff can remotely command the equipment to perform a series of operations such as depth adjustment, motor start and stop, heating temperature control, and valve opening and closing, realizing intelligent management of the entire process. The top mounting plate 2 is used for manual transfer of the entire equipment. A handle can be provided on one side of the top mounting plate 2 to assist manual operation. Multiple internal support rods 41 reinforce the connection between the moving platform 4 and the heating plate 45.
