Description

Technical Field

[0001] This utility model relates to the field of groundwater sampling and well washing technology, and in particular to a groundwater sampling device. Background Technology

[0002] Groundwater sampling methods are diverse, with conventional methods such as Bayler tube sampling, airbag pump sampling, and variable flow sampling pumps being widely used. Bayler tube sampling is simple to operate, but the representativeness of the collected water samples is easily affected by the water flow velocity and water quality within the well. Airbag pump sampling is suitable for low-permeability formations and deep groundwater, avoiding the influence of airlift and aeration on the water sample; however, its sampling efficiency is relatively low, and it requires a certain level of operator experience. Variable flow sampling is simple to operate, but it is labor-intensive. These sampling methods only extract water from the well; subsequent on-site processes such as data analysis and sample collection are required. Furthermore, sampling points are generally located in the field, requiring sampling personnel to carry numerous instruments and equipment back and forth, necessitating solutions to problems such as numerous on-site equipment, high labor costs, multiple sampling cycles, and low sampling efficiency.

[0003] The existing patent (publication number: CN221224335U) discloses "This utility model discloses a groundwater sampling device, which relates to the field of sampling device technology. This utility model includes a sampling tube, with several hanging rings fixedly connected to the top of the sampling tube. A collection bucket is fixedly connected to the inner wall of the end of the sampling tube away from the hanging rings. Several water inlet holes are opened on the outer wall of the collection bucket. A detection block is fixedly connected to the side of the collection bucket away from the hanging rings. Several fixing rings are fixedly connected to the inner wall of the sampling tube. A micro water pump is fixedly connected to the side of the fixing rings near the collection bucket. A top plate is fixedly connected to the inner wall of the sampling tube. This utility model sets a ball valve in the outlet pipe. When the device needs to divert the sample, it only needs to turn the valve. When the valve is turned, the ball valve will be turned along with it. Then, when the notch on the ball valve is aligned with the outlet pipe, the sample can be diverted from the outlet pipe, thus achieving convenient sampling and diversion to other storage areas."

[0004] In the process of developing this application, the inventors discovered the following problems with the prior art: When existing groundwater sampling devices are used, the devices usually only have the function of collecting samples and cannot achieve timely detection of samples. At the same time, the existing sampling devices are generally large in size, making them inconvenient to carry and operate when conducting field sampling operations. Their overall applicability is small and their practicality is poor.

[0005] Therefore, those skilled in the art have provided a groundwater sampling device to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a groundwater sampling device. Through the design of a telescopic frame and rollers, the device is easy to deploy, store, and move, adapting to different sampling environments. By integrating components, the number of equipment and instruments that need to be transported on-site is reduced, and the carrying load on sampling personnel is reduced by hauling, thereby improving sampling efficiency. At the same time, through structural design, the device can be stored and can achieve sampling of water samples at different flow rates and in parallel, meeting the requirements of multi-index, multi-quantity, and multi-person sampling, thus improving sampling efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

A flow regulating valve is fixedly installed on one side of each of the multiple plastic-steel converters.

[0012] Furthermore, a drain valve is fixedly installed at the lower end of one side of one of the two main skeletons.

[0013] Furthermore, a 90° movable horizontal support plate is fixedly installed at one lower end of the other side of the two main skeletons, and multiple sampling bottles are movably installed on the upper surface of the 90° movable horizontal support plate.

[0014] Furthermore, the testing cup includes a cup body, and a water outlet is fixedly provided in the middle of one side of the cup body.

[0015] Furthermore, the sampling pump deployment and retraction device is rotatably connected to the main frame. The sampling pump deployment and retraction device is equipped with a sampling pump and a water level gauge. Both can be placed or collected simultaneously by rotating the handle, allowing for real-time monitoring of water level changes.

[0016] Furthermore, a plurality of limiting blocks are fixedly provided at the upper end of the inside of the cup body, and a perforated plate is fixedly provided at the upper end of the plurality of limiting blocks.

[0017] Furthermore, a hook is fixedly installed on the upper end of one side of the cup body.
