Description

Technical Field

[0001] The invention relates to a recycling device, in particular to a sampling device for hydrogeological monitoring, belonging to the technical field of geological monitoring. Background Art

[0002] The geological environment mainly refers to the hard shell under the surface of the earth, namely the lithosphere. The geological environment is the product of the evolution of the earth. The weathering process of rocks under the action of solar energy liberates the consolidated substances and participates in the geographical environment, the geological cycle and even the interstellar matter cycle. It is a kind of natural environment, referring to the environmental system composed of the lithosphere, hydrosphere and atmosphere. In the long-term geological historical evolution process, the hydrosphere, lithosphere and atmosphere carry out material migration and energy conversion to form a relatively balanced open system. Human beings and other organisms rely on the geological environment for survival and development. At the same time, humans and other organisms are constantly changing the geological environment. In the process of hydrogeological monitoring, we need to sample the soil, which requires the use of sampling devices.

[0003] In a Chinese patent with application number CN202110162311.8, a new type of sampler for geological environment monitoring is proposed. Rollers and traction parts are provided on the support frame to facilitate the movement of the present invention. The sampling direction of the sampler body can be adjusted by the angle adjustment device, thereby improving the practicality of the device. The internal and external lifting mechanisms of the sampling device cooperate with the internal lifting mechanism to drive the sampler body for sampling. At the same time, the protective mechanism plays a supporting and protective role on the arc-shaped support platform when it is being transported or not in use, thereby improving the efficiency of sampling and reducing the labor intensity of the staff.

[0004] In the Chinese patent application number CN202210133353.3, a sampling device for hydrogeological monitoring is proposed. By controlling the second motor to drive the threaded shaft to rotate, the threaded shaft drives the internal threaded sleeve to move, and the internal threaded sleeve drives the mounting plate to move downward, and the mounting plate drives the drill tube to move downward. At the same time, the limit sleeve moves up and down on the limit rod. The scale mark on the limit rod can be observed to control the drilling depth. Before drilling, the electric push rod is controlled so that the drill bit is located on the outside of the bottom of the drill tube. The drill bit and the spiral blade make the drilling force of the drill tube strong, and the baffle can prevent The soil enters the drill barrel during drilling. When the drill barrel is observed to have reached the target depth, the electric push rod is controlled to drive the baffle and the drill bit to move upward and enter the upper part of the drill barrel. The drill barrel is then continued to drill downward, and the soil in the target area and below the target depth enters the drill barrel. The drilling is stopped, and the electric push rod is controlled to push the baffle to compact the soil inside the drill barrel to prevent the soil inside from falling when the drill barrel is moved up and taken out. After the drill barrel is taken out, the electric push rod can be controlled again to push the soil inside the drill barrel out through the baffle, thereby facilitating the removal of the soil.

[0005] However, both of the above-mentioned comparative documents have some common problems. Most of them are not flexible enough and have low collection efficiency when collecting soil. At the same time, the collection method is single. The single sampling method for different geological conditions will lead to poor sampling results or even difficulty in sampling. For this reason, we propose an optimized and improved sampling device for hydrogeological monitoring. Summary of the invention

[0006] The purpose of the present invention is to provide a sampling device for hydrogeological monitoring in order to solve the above-mentioned problems. Sampling is carried out through an automatic delivery style dual-mode sampling mechanism.

The automatic delivery style dual-mode sampling mechanism also has two sampling methods. One is to directly dig a square piece of soil to maintain a high degree of integrity, and the other is to drill and crush the soil and then roll it in, which can better sample hard soil. The combination of the two enables the device to sample different types of soil well, and the automatic delivery style dual-mode sampling mechanism is kept inside the sampling tube before sampling and does not contact the external soil.
