Description

Technical Field

[0002] After searching, the Chinese patent publication number is CN215727028U, which discloses a groundwater sampling device for hydrogeology and engineering geology, including a support leg located above the ground, a stabilizing cross plate fixedly installed on the upper surface of the support leg, a support frame fixedly installed on both sides of the upper surface of the stabilizing cross plate, a rotatable rotating rod passing through the top of the support frame, and a winding roller fixedly installed on the outer surface of the rotating rod. When using this technical solution, it requires the user to first use a drilling device to drill a hole in the ground to the groundwater, and then use a sampler to perform sampling operations. First of all, when using this device, it is not convenient for the user to carry and move it. However, groundwater sampling in geological surveys often requires sampling across multiple points, which reduces operational efficiency and flexibility. Secondly, when the device is in use, it cannot help the user perform drilling operations, and additional configuration and operation of drilling equipment are required, which not only increases the complexity of carrying tools, but also increases the cumbersomeness of the operating process. Finally, when the structure is in use, it engages the gears of the winding roller through a more complex limiting structure. In actual applications, it often faces problems such as poor gear engagement and poor operational feedback. The use effect of this structure is poor, so the device cannot meet the use requirements. Therefore, a groundwater sampling device for engineering geological surveys is proposed to solve the above-mentioned problems. Summary of the invention
