Abstract
Description
Technical Field
[0001] The invention relates to the field of groundwater detection, in particular to a karst groundwater sampling device. Background Art
[0002] The sum of various forms and hydrological phenomena formed by the destruction and transformation of soluble rocks by groundwater and surface water. Karst is a geological action of water on soluble rocks (carbonate rocks, gypsum, rock salt, etc.) mainly in the form of chemical dissolution, supplemented by mechanical actions such as erosion, subsidence and collapse of flowing water, as well as the general term for the phenomena produced by these actions. The karst environment is regarded as a fragile ecological environment like the edge of a desert. Its vulnerability is mainly manifested in: small environmental capacity, a long time for vegetation to recover after being destroyed, rapid changes in hydrological processes, frequent droughts and floods, and the transition of biological production depends on habitat conditions, but habitat conditions are significantly affected by the environment; the benign evolution of the ecological environment depends on the recovery of vegetation; the sustainable development approach between water resource utilization and land use lacks effectiveness and operability, resulting in unreasonable land use (such as slash-and-burn farming, excessive cultivation), causing serious loss of seed banks in the ecological environment and affecting species diversity. The necessity of karst groundwater sampling lies in its unique geological and hydrological characteristics. The geological structure of the karst area is complex, the groundwater flow path is complex, and it is often accompanied by strong dissolution, which may cause the water to contain special chemical components and microorganisms. These components are very important for assessing the quality of groundwater and its potential environmental impact.
[0003] Karst refers to the geological process in which groundwater dissolves and erodes soluble rocks (such as limestone, gypsum, etc.) under the action of dissolution. This process is mainly due to the reaction of carbon dioxide dissolved in groundwater with carbonates in rocks to form a carbonate solution, which then dissolves the minerals in the rocks, causing geomorphic features such as caves and dissolution troughs on the rock surface. The formation of karst is closely related to geological structure, hydrogeological conditions, climate and other factors. In terms of geological structure, karst mainly occurs in areas containing soluble rocks, such as karst areas. Hydrogeological conditions also play an important role in the development of karst, and the flow and dissolution of groundwater are the key to the formation of karst. Climate conditions can also affect the development of karst. For example, the high temperature and high humidity climate in tropical rainforest areas is conducive to dissolution. Karst landform is a unique landform type with rich caves, underground rivers, underground sediments and other characteristics. Karst areas are rich in groundwater resources and are also important tourist attractions. The study of karst landform is of great significance for the development and utilization of groundwater resources and the prevention and control of geological disasters.
[0004] However, there are still the following problems in the sampling process of existing karst groundwater:
[0005] After the existing karst groundwater is sampled, the traction and conveying mechanism moves the sampling bottle. Since the sampling bottle is prone to shaking during traction and conveying, the sampling bottle may spill, affecting the sampling effect of the sampling bottle. Therefore, it is necessary to involve a karst groundwater sampling device for use in the existing groundwater detection field. Summary of the invention
