Portable anti-jamming automatic water level tester

Abstract

A portable anti-jamming manual integrated water level tester, which has a wire hammer, a winding reel, a measuring line, a bracket, a measuring line distributor, a measuring line counting collector, a first motor, a first motor drive module, a second motor, The second motor drive module, PLC programmable controller, encoder, touch screen, brushes, 24V DC power supply. The wire hammer is composed of a plastic hose and iron powder, and the front end of the measuring line is fixedly connected with the plastic hose. The measuring line wound on the reel of the winding reel is connected to the PLC programmable controller through its tail end and the electric brush, and the signal output end of the encoder is connected to the input end of the PLC programmable controller. The output terminals of the programmable controller are respectively connected with the input terminals of the first and second motor drive modules, and the output terminals of the first and second motor drive modules are electrically connected with the first and second motors. The invention solves the problem that the wire hammer and the measuring line are stuck in the water well, has the advantages of convenient operation, accurate measurement result and convenient field use.

Description

technical field [0001] The invention relates to an instrument for automatically measuring the water level of groundwater under a water well, which is applied in the fields of hydrogeology, engineering geology, etc., in particular to a portable anti-jamming and automatic integrated water level tester. Background technique [0002] At present, there are two types of known water level testing devices. One type of structure is composed of a multimeter, an electric wire, a spool and a plumb weight. In the water well, when the lead weight reaches the water surface, the multimeter at the end of the wire is connected, and the pointer swings to indicate that it has reached the water surface. The groundwater level in the well is measured through the scale marked on the wire, and finally the wire and the lead weight are retracted manually. But in the whole measurement process, there are several problems: [0003] First: The lead weight may be stuck in the water pump or other equipment...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a portable anti-jamming integrated water level tester, which can not only effectively solve the problem that the wire hammer and the measuring line (wire) are stuck in the well, but also Realize the full-automatic operation of manual integration in the whole process, and the operation is convenient, the measurement results are accurate, and it is convenient for field use
