Embodiment 1

[0038] see Figure 1-6 , the present invention provides a technical solution:

[0039] In this embodiment, the same part as in Embodiment 1 will not be repeated, the difference is:

[0040] A hydrogeological drilling water level automatic acquisition device, comprising a water intake pipe 5, a water level acquisition module and a central acquisition host computer 4, the water intake pipe 5 passes through the soil layer 3 and penetrates downward into the aquifer 2 above the aquifer 1, and the water level The acquisition module includes a water level acquisition box 6 and a data transmission module 9. The data transmission module 9 is used for exchanging information between the water level acquisition module and the central acquisition host computer 4. The outside of the top of the water intake pipe 5 is connected to the inside of the water level acquisition box 6. The water intake pipe The quantity of 5 is at least 3, and the height of the bottom end of the water intake pipe 5...

Embodiment 2

[0043] see Figure 1-6 , the present invention provides a technical solution: the water line information module includes a water level tube 18, a submersible pump 30 and a laser receiver 17, the water level tube 18 is made of glass material, and the water level tube 18 is fixedly arranged on the inside of the water level collection box 6, and the water level The inner side of the top of the pipe 18 communicates with the inner side of the water level collection box 6 through the through hole. The top of the water pipe 5 is connected, the submersible pump 30 is fixedly arranged on the bottom inside of the water level collection box 6, the output end of the submersible pump 30 is connected with the top inside of the water level pipe 18, and the input end of the submersible pump 30 is arranged on the water level collection box 6. Under this arrangement, when the water level of the water level pipe 18 is too high and overflows, and then descends, the submersible pump 30 can pump ou...

Embodiment 3

[0047] see Figure 1-6, the present invention provides a technical solution: the air pressure information module includes an air chamber 11 and a sliding rheostat 28, the inner side of the air chamber 11 communicates with the inner side of the water level collection box 6, and the inner side of the air chamber 11 is slidably connected with a slider 25, when the groundwater After the level changes, the water level in the water level pipe 18 and the water intake pipe 5 changes. Correspondingly, the pressure inside the water level collection box 6 will change. When the groundwater level rises, the slider 25 will move to the left. , the slider 25 will move to the right, and the specific position of the slider 25 will be judged by reading the current in the sliding rheostat 28 circuit at this time, and the groundwater depth H at this time will be calculated to realize a wide range of groundwater depth H. Monitoring, the outside of the air cavity 11 is fixedly connected with a secon...

Abstract

The present invention relates to the technical field of geological exploration, in particular to a hydrogeological drilling water level automatic acquisition device and method, the water level acquisition module includes a water level acquisition box and a data transmission module, the data transmission module is used for the water level acquisition module and the central acquisition host computer For the exchange of information, the outside of the top of the water intake pipe is connected to the inside of the water level collection box, the number of the water intake pipes is at least three, and the height of the bottom end of the water intake pipe is equal to the height of the top end. , on the one hand, the monitoring error can be reduced by taking the average value of the measurements at the three locations; The acquisition module realizes information communication with the central acquisition host computer through the data transmission module, and the water level acquisition module includes an air pump, a fixed module, a water line information module, an air pressure information module and an air pressure compensation module.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a device and method for automatically collecting water levels in hydrogeological boreholes. Background technique [0002] At present, for the measurement of groundwater level in geological exploration, relevant units at home and abroad only use their own subject knowledge and equipment with very limited uses, and there is no device that can track and detect groundwater level in real time. For example, when an observation well is opened, it is convenient to lower the water level gauge into the water layer, obtain the height of the water level gauge from the water surface through the sensing device, and then calculate the height of the water level from the surface wellhead through the length of the wire under the wellhead. However, this method is too limited, has large errors, and is affected by various factors such as terrain, strata, and its own structure, so it ca...
