Description

Technical Field

[0001] The present invention belongs to the technical field of sampling devices, and more specifically, particularly relates to a geological exploration sampling device with a water intake function. Background Art

[0002] In the field of geological exploration, in order to understand the underground geological structure and water resource situation, professional sampling devices are often required to collect underground samples and obtain water samples in stages. For example, when studying areas with multi-layer geological structures where each layer may contain water resources with different characteristics, it is necessary to conduct sampling and analysis at different stratigraphic depths respectively to evaluate the impact of the geological structure on groundwater, analyze the vertical changes in the composition of underground water resources, and study the relationship between geological changes and hydrological changes, etc.

[0003] However, in the actual process of geological exploration sampling, in the traditional geological exploration sampling device, during the first sampling, due to factors such as heat generation caused by the friction between the drill bit and soil / rock, and changes in formation pressure, the water intake channel will be disturbed to varying degrees. The debris generated by friction is easily mixed into the water sample, resulting in water sample contamination. This will not only affect the subsequent analysis of the water sample composition, causing deviation in the first sampling result, but also block the internal channel of the water intake device due to excessive impurities, increasing the risk of equipment failure before the second sampling, thereby reducing the efficiency of the entire sampling work.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the setting of the water seepage ring on the outer cylinder, the device can preliminarily filter the incoming water during the sampling process, improving the purity of the water sample obtained by the device. The water seepage ring is composed of a metal filter ring and a ceramic filter ring. The arc-shaped partition in the middle cavity divides it into multiple groups of water seepage cavities. The compression spring and pressing plate structure in the water seepage cavity can be sealed by the centrifugal force when the outer cylinder rotates downward. The pressing plate slides on the slide rail structure through the centrifugal force and moves along the direction of the compression spring to ensure the tightness of the seal between the metal filter ring and the pressing plate, preventing impurities from entering when the device is in the rotating state of the outer cylinder, and improving the dust-proof ability of the device to cope with complex geological environments.

[0016] 2. When using the device, the cooperation of the filter hopper, impeller and scraper on the filter cylinder can be used to clean the impurities in the water, making the device not easily blocked during the water intake process and improving the smoothness of the water intake of the device. The filter hopper cooperates with the end cover with a spiral distribution of water inlet channels to guide the water flow into. The impeller rotates driven by the drive motor, driving the scraper to clean the impurities on the filter hopper and discharging them through the slag discharge port. Then, through the setting of the filter plate at the bottom of the filter cylinder and the water outlet, the device can further purify the water sample and smoothly introduce it into the water intake cavity, ensuring that the obtained water sample meets the subsequent analysis requirements and improving the quality and reliability of the water intake of the device.

[0017] 3. Through the setting of the magnetic float and control module in the receiving cylinder, the device can monitor the water level in the receiving cylinder, improving the monitoring ability of the device for the water intake state. The magnetic float rises and falls with the water level, approaches or moves away from the reed switch, and transmits the triggered signal to the control module. The device uses this water level sensing mechanism to timely feedback the water intake progress, enabling the operator to grasp the water intake situation and then adjust the operation in a timely manner, improving the controllability and adaptability of the device during the water intake process.

[0018] 4. The placement table in the collection assembly is connected to the base through the support column and the buffer column, which can absorb the vibration generated during the operation of the device and avoid the impact of vibration on other components and samples. The electric push rod and clamping ring on the placement table can be operated by the control module to adjust the position and fix the sampling cylinder. The vibration motor at the bottom of the placement table can perform vibration processing on the samples on the placement table under the control of the control module, promoting the separation of the samples from the sampling cylinder, improving the processing ability of the device for the samples, and facilitating the subsequent sample analysis.

Through this setting, the change in the water level inside the receiving cylinder 205 can be sensed and corresponding control can be made, enabling the user to master the water intake state. A guiding tube 404 is provided inside the receiving cylinder 205, and a magnetic float 405 is provided inside the guiding tube 404. The magnetic float 405 rises and falls with the water level, approaches or moves away from the reed switch 402, and the trigger signal is transmitted to the transmitting control module 301. The device uses this water level sensing mechanism to timely feedback the water intake progress.

[0036] In Embodiment 1, only the magnetic float 405 is relied on to trigger the reed switch 402 to control the operation of related components. In Embodiment 2, a damping ring 406 is added to the magnetic float 405. When the water level in the water intake cavity changes, the magnetic float 405 moves inside the guiding tube 404. The damping ring 406 is slidably connected to the guiding tube 404, and can slow down the moving speed of the magnetic float 405. In this way, the frequent mis-triggering of the reed switch 402 caused by too fast water level fluctuations can be avoided, and the signal received by the transmitting module 401 is more stable and accurate. For example, when conducting exploration sampling in some areas with complex geological structures and unstable underground water flow velocities, the water level fluctuates violently. In the device of Embodiment 1, the reed switch 402 may be frequently opened and closed due to the rapid movement of the magnetic float 405, resulting in signal disorder. However, through the setting of the damping ring 406 in Embodiment 2, this problem can be overcome, making the water intake control of the receiving cylinder 205 more reliable, and improving the adaptability and stability of the device under complex hydrogeological conditions. The remaining conditions are the same as those in Embodiment 1, so this embodiment will not be elaborated further.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For a person skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments.
