Automatically controlled fully penetrating well water pumping simulator

Abstract

The invention relates to a fully penetrating well water pumping simulator applied to teaching trial, which overcomes shortages of big volume, trivial experiment operation and inaccurate experimental data, etc. The measures are as follows: the automatically controlled fully penetrating well water pumping simulator comprises a pedestal 1 which is provided with a mechanical simulation system and an electrical control system connected with the mechanical simulation system; the mechanical simulation system is composed of an annular conducting ring 2, a conducting bearing rod 3, a groove-shaped feeling arm 4, a driving motor 5, a feeling arm motor 6, a position sensor 7, a mark pole sensor 8, a driving screw rod 10, a vernier 11, a probe 12, a probe groove 13 and an angle mark pole 14; the electrical control system is composed of a display module 16, a data result storing module 17, an alternative signal generating module 18, a motor driving module 19, an analog-to-digital conversion module 20, a user interface 21, a serial port communication module 22 and a power supply module 23 which are respectively connected with a central processing unit 15 through conducting wires. The feeling arm motor 6 is connected with the groove-shaped feeling arm 4 which slides on the annular conducting ring 2.

Description

technical field [0001] The invention relates to a simulation device for teaching experiments, in particular to a complete well pumping simulation device capable of automatic control. Background technique [0002] In the current research on the movement of groundwater, mechanical simulation devices based on water simulation principles are often used and completed by manual operation, such as the traditional sand tank simulation device. Although it solves the abstract problem using mathematical methods, it makes the practitioner more intuitive Understand the movement of groundwater, but due to the large volume, cumbersome experimental operations, and inaccurate experimental data, it is difficult to generalize, and the production cost is high. The simulation device improved on the basis of the sand tank simulation device, that is, the Chinese patent announcement number is CN100446052C patent document, which includes a water storage tank with a water pump, a simulation box with ...
