Description

Technical Field

[0001] The utility model relates to the technical field of saline-alkali land monitoring, in particular to a saline-alkali land water and salt movement dynamic monitoring device. Background Art

[0002] Saline-alkali land monitoring refers to the regular or irregular observation and analysis of various indicators of saline-alkali land in order to understand the current status, changing trends and management effects of saline-alkali land. The movement of water and salt in the soil with changes in time and space is called water-salt migration. The monitoring of water-salt migration data in saline-alkali land generally uses corresponding dynamic monitoring devices.

[0003] Because the movement of water and salt in the soil will directly affect the conductivity of the soil, most of the existing dynamic monitoring devices for water and salt movement in saline-alkali land use the method of burying electrodes in the soil to monitor the conductivity in the soil in real time, and then judge the data of water and salt movement in saline-alkali land. However, most dynamic monitoring devices for water and salt movement lack a depth adjustment structure that can adjust the monitoring depth, resulting in the application scenarios of the dynamic monitoring devices being relatively limited and inconvenient to use.

[0004] Therefore, those skilled in the art have provided a device for monitoring the dynamic movement of water and salt in saline-alkali land to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0005] The purpose of the utility model is to provide a device for monitoring the movement of water and salt in saline-alkali land to solve the problems raised in the above-mentioned background technology.

[0007] A saline-alkali land water and salt transport dynamic monitoring device comprises a monitoring body, and a monitoring depth adjustment mechanism is arranged on the outer side of the monitoring body;

[0008] The monitoring depth adjustment mechanism includes a fixed cylinder, a movable cylinder is slidably connected inside the fixed cylinder, a movable rod is slidably connected inside the movable cylinder, a detection electrode is fixedly connected to the top of the movable rod, a first hand-tightened tightening bolt is threadedly connected to the inner wall of the fixed cylinder, a second hand-tightened tightening bolt is threadedly connected to the inner wall of the movable cylinder, and a button controller is fixedly connected to the front of the monitoring body.

[0009] As a further solution of the utility model: the bottom end of the fixed cylinder is fixedly connected to the upper surface of the monitoring body, the end of the first hand-tightening bolt close to the movable cylinder is in contact with the outer surface of the movable cylinder, the end of the second hand-tightening bolt close to the movable rod is in contact with the outer surface of the movable rod, the monitoring body and the detection electrode are electrically connected to the button controller through wires, the bottom surface of the monitoring body is fixedly connected to a handle rod, and the outer surface of the handle rod is fixedly connected to a first anti-slip sleeve.

[0010] As a further solution of the utility model: a threaded ring is fixedly connected to the upper surface of the monitoring body, a protective shell is arranged above the monitoring body, and the inner wall of the protective shell is threadedly connected to the outer surface of the threaded ring.

[0011] As a further solution of the utility model: a second anti-skid cover is fixedly connected to the outer surface of the protective shell, and a plurality of identical anti-skid protrusions are fixedly connected to the outer surface of the second anti-skid cover.

[0012] As a further solution of the utility model: two first limit sliding blocks are fixedly connected to the outer surface of the movable cylinder, and the outer surface of each of the first limit sliding blocks is slidably connected to the inside of the fixed cylinder.

[0013] As a further solution of the utility model: two second limit sliding blocks are fixedly connected to the outer surface of the movable rod, and the outer surface of each of the second limit sliding blocks is slidably connected to the inside of the movable cylinder.

The detection electrode can extend a certain length from the inside of the movable cylinder along with the movable rod, and the movable cylinder can extend a certain length from the inside of the fixed cylinder. In addition, the first hand-tightening jacking bolt can tighten the movable cylinder after being threadedly connected to the fixed cylinder, and the second hand-tightening jacking bolt can tighten the movable rod after being threadedly connected to the movable cylinder, so that the monitoring depth of the detection electrode can be adjusted and fixed, which plays a role in adjusting the monitoring depth of the detection electrode and increasing the application scenarios and convenience of use of the monitoring device, avoiding the problem that the application scenarios of the dynamic monitoring device are relatively limited and the use is relatively inconvenient due to the lack of a depth adjustment structure that can adjust the monitoring depth.

[0024] The inner wall of the fixed cylinder 202 is threadedly connected with a first hand-tightened tightening bolt 206, and one end of the first hand-tightened tightening bolt 206 close to the movable cylinder 203 contacts the outer surface of the movable cylinder 203, and the outer surface of the protective shell 5 is fixedly connected with a second anti-slip sleeve 7, and the outer surface of the second anti-slip sleeve 7 is fixedly connected with a plurality of identical anti-slip bosses 8. By providing the anti-slip bosses 8, the friction force of the outer surface of the second anti-slip sleeve 7 can be increased. By providing the second anti-slip sleeve 7 and the anti-slip bosses 8, the two can jointly increase the friction force of the outer surface of the protective shell 5, thereby facilitating the twisting of the protective shell 5 and disassembly of the protective shell 5.

[0025] The inner wall of the movable cylinder 203 is threadedly connected with a second hand-tightened tightening bolt 207, and one end of the second hand-tightened tightening bolt 207 close to the movable rod 204 is in contact with the outer surface of the movable rod 204.

After that, after the soil in the saline-alkali land is loosened, hold the handlebar 3 and the first anti-slip sleeve 4 by hand to insert the detection electrode 205 downward through the loosened saline-alkali land soil, then fill the soil at the junction of the fixed cylinder 202 and the monitoring body 1 and place the entire device stably. Finally, operate the button controller 201 to connect the detection electrode 205 and the monitoring body 1, so that the detection electrode 205 starts real-time monitoring. The real-time data can be reflected on the small screen of the button controller 201 and the data is stored. The design of the entire saline-alkali land water and salt transport dynamic monitoring device effectively solves the problem that the application scenarios of the dynamic monitoring device are relatively limited and inconvenient to use due to the lack of a depth adjustment structure that can adjust the monitoring depth.
