Description

A sampling device for hydrogeological monitoring

technical field

The invention relates to a recycling device, in particular to a sampling device for hydrogeological monitoring, and belongs to the technical field of geological monitoring.

Background technique

The geological environment mainly refers to the hard shell layer under the earth's surface, that is, the lithosphere. The geological environment is the product of the earth's evolution. The weathering process of rocks under the action of solar energy releases the consolidated substances and participates in the geographical environment. It participates in the geological cycle and even the interstellar material cycle. In the process of hydrogeological monitoring, we need to Sampling the soil, which requires the use of a sampling device.

In the Chinese patent with the application number CN202110162311.8, a new type of sampler for geological environment monitoring is proposed. The support frame is provided with rollers and traction parts, so as to facilitate the movement of the present invention, and the sampler can be adjusted through the angle adjustment device. The sampling direction of the body improves the practicability of the device. Through the cooperation of the internal and external lifting mechanisms of the sampling device with the internal lifting mechanism, the sampler body can be driven for sampling. At the same time, when the protective mechanism is in transit or not in use, it will play a role in the arc-shaped support platform. Support protection, improve the efficiency of sampling, and reduce the labor intensity of the staff.

In the Chinese patent with the application number CN202210133353.3, a sampling device for hydrogeological monitoring is proposed. By controlling the second motor to drive the rotation of the threaded shaft, the threaded shaft drives the movement of the internal thread sleeve, and the internal thread sleeve drives the mounting plate to move down, The mounting plate is moved down with the drill pipe, and the limit sliding sleeve moves up and down on the limit rod. Observe the scale mark on the limit rod to control the drilling depth. Before drilling, control the electric push rod so that the drill bit is in the drill position. On the outside of the bottom of the barrel, the drill bit and the helical blade make the drilling force strong, and the baffle can prevent the soil from entering the inside of the drill barrel during drilling. rod to drive the baffle plate and the drill bit up into the top of the drill pipe, and then continue to drill the drill pipe downward, the target area and the soil below the target depth will enter the interior of the drill pipe, stop drilling, control the The electric push rod pushes the baffle to compact the soil inside the drill pipe, preventing the soil from falling when the drill pipe is moved up and taken out. After the drill pipe is taken out, the electric push rod can be controlled to pass the block The plate pushes out the soil inside the drill barrel, making it easy to remove the soil.

However, the above two comparison documents have some common problems. Most of them are not flexible enough in soil collection, and the collection efficiency is low. At the same time, the collection method is single. For different geological sampling methods, a single sampling method will lead to poor sampling effect or even difficult sampling. Therefore, we propose an optimized and improved sampling device for hydrogeological monitoring.
