Multilayer underground water level observation device for hydrogeological hole

Abstract

The invention discloses a multilayer underground water level observation device for a hydrogeological hole. The multilayer underground water level observation device comprises a liquid storage barrel,wherein a middle shaft is fixedly connected between the inner walls of the two sides of the liquid storage barrel; the outer wall of the middle shaft is slidably connected with a push-pull disc; a sealing gasket is arranged between the push-pull disc and the middle shaft; two lead screws are movably connected to the inner wall of the bottom part of the liquid storage barrel; the other ends of thetwo lead screws penetrate through the upper side barrel wall of the liquid storage barrel to be fixedly connected with secondary wheel discs; two threaded holes are formed in the push-pull disc; theinner walls of the threaded holes are movably connected with the outer walls of the lead screws; a motor box is fixedly connected to the outer wall of the upper side of the liquid storage barrel; anda first motor is fixedly connected to the inner wall of the motor box. The multilayer underground water level observation device can perform water absorption and water outlet operation on undergroundwater, facilitates underground water sampling and later water pumping detection, solves the problem that a water body is difficult to take out after sampling, improves the underground water level observation efficiency, can use a motor to replace manpower, and reduces the working intensity.

Description

technical field [0001] The invention relates to the technical field of hydrogeology, in particular to a multi-layer groundwater level observation device for hydrogeological holes. Background technique [0002] The content of water level observation includes river bed changes, flow potential, flow direction, flood diversion, ice conditions, aquatic plants, waves, wind direction, wind force, water surface relief, water temperature and other factors that affect water level changes. When necessary, the slope of the water surface is also measured. [0003] At present, the water level observation of multi-layer groundwater is to directly lower the sampling device into the groundwater for sampling. Since the direct container sampling method is adopted, the sampling process is relatively slow, and the container needs to be inspected before it is raised to the ground for testing after sampling. It is very inconvenient to extract the liquid after the container is sealed. Therefore, a ...

[0003] At present, the water level observation of multi-layer groundwater is to directly lower the sampling device into the groundwater for sampling. Due to the direct container sampling method, the sampling process is relatively slow, and the container needs to be inspected before it is raised to the ground for testing after sampling. It is very inconvenient to extract the liquid after the container is sealed. Therefore, a multi-layer groundwater level observation device for hydrogeological holes is proposed to facilitate the sampling and detection of groundwater.
