Abstract

The invention provides a signal acquisition device. The signal acquisition device comprises a signal source, power supply electrodes, a detection electrode and a signal acquisition module. The power supply electrodes comprise the first power supply electrode and the second power supply electrode which are arranged in parallel in the horizontal direction and connected with two signal output ends of the signal source through power supply cables respectively. The signal source provides alternating signals for the power supply electrodes. The detection electrode is parallel to both the first power supply electrode and the second power supply electrode and connected with the signal acquisition module through a signal cable. According to the signal acquisition device, during laying of a vertical anti-seepage membrane, alternating signals are applied to two sides of the vertical anti-seepage membrane to acquire potential on the surface of the vertical anti-seepage membrane so that seepage property detection of the vertical anti-seepage membrane can be subsequently performed according to the acquired potential conveniently; by means of the signal acquisition device, the potential of a sampling point on the surface of the single side of the vertical anti-seepage membrane can be acquired accurately, and accordingly it is ensured that seepage detection can be performed on the vertical anti-seepage membrane accurately and effectively.

Description

technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a signal acquisition device. Background technique [0002] Nowadays, water resources are seriously scarce, and most drinking water resources are groundwater. Therefore, how to protect the cleanliness of groundwater resources is particularly important. At present, urban domestic waste landfills are mostly set above the groundwater layer, and the groundwater protection of heavy metal-contaminated sites is becoming more and more serious. How to ensure that pollutants do not leak into the groundwater and prevent groundwater from being polluted has become the most important issue in the construction process. . [0003] The laying of vertical anti-seepage membrane has become an increasingly important measure to protect groundwater. Its function is to isolate the inside and outside of the polluted area, control the spread of polluted groundwater to the sur...
