Novel groundwater flow direction measuring instrument

Abstract

The invention relates to special equipment for groundwater flow direction measurement, specifically to a novel groundwater flow direction measuring instrument. The measuring instrument determines a groundwater flow direction through a coaxial pointer and a ribbon connected thereto, direction information directly acts on an annular resistor connected with the coaxial pointer through the coaxial pointer, the annular resistor is connected and fixed to the coaxial pointer and a geomagnetic circle, so that the annular resistor is located in a fixed orientation all the time, the annular resistor isconnected with a built-in circuit, two ends of the resistor are equipped with current measuring device to measure resistor current, and a resistance value is judged through a current value. The equipment provided by the invention has the characteristics of high system adaptability, high information automation degree and safe and reliable information acquisition. Groundwater information intensivismis realized, various data output protocols are provided, the integrating degree of integration of equipment monitoring data and a corresponding application system is improved, and the difficulty of extraction and utilization of related application data is lowered.

Description

technical field [0001] The invention belongs to the technical field of water conservancy information. Specifically relates to a novel groundwater flow direction measuring instrument. Background technique [0002] my country has a long history of hydrology. As early as more than 4,000 years ago, our ancestors began to control water according to the laws of hydrology. Before 2,000 years ago, we gradually began to observe information such as water level, rainfall, and flow. After the founding of New China, the Party Central Committee attached great importance to flood control and disaster reduction and water conservancy construction, and hydrological undertakings also developed rapidly. Hydrological information monitoring stations also spread all over the country, playing an important role in disaster prevention and mitigation, economic construction and various social constructions in our country. effect. As the role of groundwater in the utilization of water resources in my ...

Problems solved by technology

As the role of groundwater in the utilization of water resources in my country is becoming more and more obvious, the requirements for monitoring the groundwater environment are becoming more and more stringent. In groundwater monitoring, equipment often needs to be placed 100 meters or even deeper underground. , has the characteristics of being difficult to operate and invisible. The traditional method of collecting groundwater flow direction information, such as DC charging method, hydrological exploration such as water level drop, or water level inversion, is used to measure the groundwater level. Direct, the measurement results need to be converted by professionals, and the disadvantages of poor operability of the equipment. So far, there is a lack of methods and equipment for intuitively measuring the flow direction of groundwater
