Embodiment Construction
[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.
[0020] according to Figure 1~4 , including a probe 1, a connecting rod 9, and a hydraulic lifting device 11, the probe 1 is connected to the connecting rod 9, and the connecting rod 9 is fixed on the upper panel of the hydraulic lifting device 11.
[0021] The probe 1 is bullet-shaped as a whole, and the top of the cavity is equipped with an air inlet pipe 3 and an air outlet pipe 4. There are two round holes in the middle of the probe, and permeable stones 2 are respectively embedded in the round holes. The permeable stone 2 and the A sealing valve 8 is provided at the junction in the cavity of the probe 1 , and a sealing valve 6 is provided at the bottom of the outlet pipe 4 . The bullet-shaped probe has less resistance and is easy to penetrate into the soil. The fun...

Abstract
The invention provides a water intake device for groundwater without drilling, which comprises a probe, a connecting rod and a hydraulic lifting device, wherein the probe is connected with the connecting rod, and the connecting rod is fixed on the upper panel of the hydraulic lifting device. The profile of the probe is bullet-shaped; a gas inlet pipe and a gas outlet pipe are installed at the topof the internal of a cavity; two round holes are formed in the middle of the probe; water-permeable stones are embedded in the round holes, respectively; seal valves are arranged on the internal jointparts between the water-permeable stones and the probe cavity; and a seal valve is arranged on the bottom of the gas outlet pipe. The device is different from the traditional way of taking a water sample; additional drilling is not required; the way of combining hydraulic pressure and gas pressure is adopted; the interaction between an impermeable layer and a permeable layer is fully utilized; and the problem of water sample pollution caused by surface water entering groundwater is put an end to.
Description
technical field [0001] The invention relates to the field of groundwater intake counting, in particular to a groundwater intake device without drilling. Background technique [0002] In the environmental monitoring work, it is necessary to take water samples and analyze the groundwater of the site. The traditional method is to collect water samples after drilling on site. This method of drilling is expensive and cannot effectively isolate surface water from entering groundwater. It will cause disturbance of groundwater samples and requires long-term observation and analysis. . In addition, the storage and storage of the boreholes are difficult. Contents of the invention [0003] The invention provides a groundwater water intake device without drilling to solve the problems of disturbing the water sample caused by surface water entering the groundwater when collecting the water sample, high drilling cost and difficulty in preservation. [0004] The invention provides a g...
