Underground water level observer for hydrogeological exploration

Abstract

The invention discloses an underground water level observer for hydrogeological exploration, and belongs to the technical field of hydrogeological exploration. The underground water level observer for hydrogeological exploration comprises an observation box, the output end of a motor is coaxially connected with a crank A, a water level prompting assembly is fixedly arranged on the left side of the middle of the upper portion of the observation box through a fixing base, a pull rod is rotationally connected to the interior of a shell through a pin shaft, the front end of the pull rod is coaxially connected with an arc-shaped rack, and a middle shaft is rotatingly connected to the middle part of the shell; a plurality of square rods are fixedly arranged at the upper end of the middle shaft in a triangular structure, and the structures are tightly matched, so that when a measurer measures through a conical floating block and a scale rope, when the scale rope reaches the water level, a sound can be made in time to remind the measurer, and the measurer can know whether the rope is excessive or not; therefore, the scale rope collecting and releasing condition can be accurately mastered, the water level observation efficiency is improved, meanwhile, the measurement accuracy is improved, the accuracy of a data collection result is guaranteed, and a powerful guarantee is provided for data analysis.

Description

technical field [0001] The invention relates to the technical field of hydrogeological exploration, and more specifically relates to a groundwater level observer for hydrogeological exploration. Background technique [0002] Hydrogeology, a branch of geology, refers to the various changes and movements of groundwater in nature. Hydrogeology is the science that studies groundwater. It mainly studies the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational use, and the adverse effects of groundwater on engineering construction and mining and its prevention and control. With the development of science and the needs of production and construction, hydrogeology is divided into sub-disciplines such as regional hydrogeology, groundwater dynamics, hydrogeochemistry, water supply hydrogeology, ore deposit hydrogeology, and soil improvement hydrogeology. Hydrogeological exploration is hyd...

Problems solved by technology

According to different purposes, tasks, requirements and scales, hydrogeological surveys can be divided into comprehensive hydrogeological surveys and specialized hydrogeological surveys. At present, the tools for observing water levels are all used through line The water level is measured by pulling and releasing the rope, but no matter whether the pulling and releasing of the rope is done by tools or manually, there will always be more strings, and the extra strings will not be retracted because the float floats on the liquid surface , resulting in a certain degree of measurement error

The prior art publication number is that the literature of CN206801559U provides a kind of hydrogeological prospecting groundwater level observation device, and this device is provided with slide frame, measuring device, fixed line head frame, measuring line, pulley, scroll spring, soft belt, floating ball, weight The design of the block, roller shaft, roller frame, roller and suspension wire enables the measuring device to rise and fall vertically, cooperates with the measuring line in the measuring device, and can observe the water level according to the length of the wire pulled out by the measuring device, and make the observation data More accurate, in addition other existing CN211178646U, CN210981422U all are the measurement of underground water level purely relying on the experience of the operator, and need not need to carry out the auxiliary operation such as touch water and other loose ropes with the help of no sensor, although this device has beneficial effect There are many, but there are still the following problems: the device directly measures through the floating ball and the rope, and the surveyor cannot know whether the rope is excessive, so it is impossible to grasp whether the retraction is excessive, and it is impossible to remind the measurer when the water level is reached, so Even if the accuracy of multiple measurements is not high, it will affect the purpose of hydrogeological exploration and the results of data collection. At the same time, when measuring water levels at different depths, different lengths of scale ropes are required. At this time, arcs of different sizes need to be used. This device cannot do this, so it is very inconvenient to replace the winding shaft with other specifications. In view of this, we propose a groundwater level observer for hydrogeological exploration
