Problems solved by technology

[0002] At present, there is no special instrument for testing the depth of groundwater, only devices for detecting the depth of groundwater. These devices use measuring ropes to measure the depth of groundwater on a regular basis. Due to the discontinuous measurement and manual readings, it is impossible to test The rate of change of groundwater depth at any time

Embodiment Construction

[0029] see figure 1 , the buoy type groundwater depth rate meter, including a water filter pipe 4, a magnetic-sensitive groundwater depth rate sensor 11, a buoy 6, the water filter pipe 4 is vertically buried in the ground 1, and the magnetic-sensitive groundwater depth rate sensor 11 is set Above the water filter pipe 4 and above the ground 1, the magnetic-sensitive groundwater depth rate sensor 11 is covered with a casing 8. The water filter pipe 4 is in the shape of a circular tube with an upper end opening and a bottom plate at the lower end. The bottom plate of the water filter pipe 4 and the side There are evenly distributed permeable filter holes 5 on the wall, groundwater 2 seeps into the filter pipe 4, and a buoy 6 floats on the water surface in the filter pipe 4, and a stainless steel wire 7 is attached to the center of the top surface of the buoy 6; see Figure 2A , Figure 2B , Figure 2C and Figure 2D and Figure 3A , Figure 3B and Figure 3C The magnetic-...

Abstract

The invention discloses a pontoon-type groundwater burial depth rate instrument and a testing method thereof. The pontoon-type groundwater burial depth rate instrument includes a water filtering pipe, a float bowl, a magnetic-sensing groundwater burial depth rate sensor and the like. The pontoon-type groundwater burial depth rate instrument and the testing method thereof can be used for continuous uninterrupted testing at any time, output groundwater burial depth and variation rate data thereof at the measuring point in a wireless manner, have the characteristics of big range, high accuracy, automation, reliability and the like, and are the instrument equipment for detecting the ground water table variation rate.

Description

technical field [0001] The invention relates to a groundwater depth rate meter and a testing method thereof, in particular to a buoy type groundwater depth rate meter and a testing method thereof. Background technique [0002] At present, there is no special instrument for testing the depth of groundwater, only devices for detecting the depth of groundwater. These devices use measuring ropes to measure the depth of groundwater on a regular basis. Due to the discontinuous measurement and manual readings, it is impossible to test The rate of change of groundwater depth at any time. Contents of the invention [0003] Aiming at the shortage of existing instruments and equipment for measuring groundwater depth rate, a buoy-type groundwater depth rate meter and its testing method are proposed. It can conduct continuous and uninterrupted testing, and wirelessly output the groundwater depth and its changes at the measuring point in real time. rate data. [0004] The present inve...
