Problems solved by technology

However, the size of the resistance is greatly affected by the soil texture, such as particle distribution, temperature difference and other factors, so it may lead to a large error in the measurement results
[0007] When testing the soil moisture content of the lake wetland soil, it is necessary to sample the deep soil below the surface and the soil in the river channel. It is inconvenient for vehicles to drive in the survey site, and the fluctuation of the lake water level makes the sampling environment more complicated. adversely affect

Embodiment 1

[0037] see Figure 1-5 , a device for monitoring soil moisture content of Tongjiang lake wetland under the condition of water level fluctuation, which includes a bearing plate 1 for supporting and installing the entire device; the left and right sides of the bearing plate 1 are symmetrically arranged to drive the entire device Moving wheels 4; the top side of the bearing plate 1 is provided with an active cavity 7, and the inside of the active cavity 7 is provided with a sampling device 2 for adopting soil, on the bearing plate 1, and located The side of the sampling device 2 is provided with a working system 3 for soil sample detection. By adopting the above-mentioned monitoring device, its operation is simple and convenient, and the wetland soil can be sampled and the moisture content can be measured under the condition of lake water level fluctuation, and the detection result can be obtained in a relatively short period of time, providing reliable data for lake governance. ...

Embodiment 2

[0047] The method for using the soil moisture content monitoring device for Tongjiang Lake Wetland under the condition of water level fluctuation includes the following steps:

[0048] Step1: When the device of the present invention is actually used, the device of the present invention is placed on the ground so that the anti-skid teeth 37 are in contact with the ground, thereby effectively improving the stability of the present invention and the ground. At this time, the sampling device 2 is above the ground and then downward Move the hollow threaded rod 14 of the sampling device 2 to the required depth inside the soil. At this time, the soil inside the hollow threaded rod 14 is the sampling soil, and then move the hollow threaded rod 14 upwards. Since the sampled soil has humidity, the sampled soil adheres to the hollow space. The inside of the threaded rod 14 moves upward together with the hollow threaded rod 14 to take the hollow threaded rod 14 out of the movable cavity 7 ...

Embodiment 3

[0054] When using the device of the present invention to measure the water content of lake soil, in order to prevent the water body from contacting the hollow threaded rod in the sampling device before the detection and thus affecting the subsequent detection results, the device of the present invention should carry out water operations when sampling the soil of the river channel. The method of using the device includes the following steps:

[0055] Step1: Move the sampling device 2 up to the top of the loading plate 1, clamp the sampling device 2 with the universal clamp 12, then take out the four support rods 9 from the placement slot 6, and adjust the angle of the support rods 9 through the rotating shaft 8, Insert the support rods 9 into the soil at the bottom of the lake, and then adjust the length of the four support rods 9 through the screw 10 to keep the whole device stable and level, which is convenient for subsequent collection of soil samples and determination of soi...

Abstract

The invention provides a river-through lake wetland soil moisture content monitoring device and method under a water level fluctuation condition. The river-through lake wetland soil moisture content monitoring device comprises a bearing plate for supporting and mounting the whole device, wheels used for driving the whole device to move are symmetrically arranged on the left side and the right side of the bearing plate correspondingly, a movable cavity is formed in one side of the top of the bearing plate, a sampling device used for sampling soil is arranged in the movable cavity, and a working system used for soil sample detection is arranged on the bearing plate and located on the side face of the sampling device. The device can be used for sampling wetland soil and measuring the moisture content under the condition of lake water level fluctuation, can obtain a detection result in a short time, and provides reliable data for lake treatment.

Description

technical field [0001] The invention relates to a device and method for monitoring the soil moisture content of Tongjiang lake wetland under the condition of water level fluctuation, and belongs to the technical field of soil detection equipment. Background technique [0002] Water is the source of life and one of the necessary conditions for the survival of living things. In a region, the soil moisture content directly affects the growth of crops in the region, and is also one of the important factors affecting crop quality and yield. Therefore, proper moisture content of the soil is a key factor for plant survival. The detection of soil moisture content is the key technology to control soil moisture. The soil water content detected by scientific methods is the basis for realizing the control of soil water content. If the soil water content can be accurately detected, it is not only beneficial to the growth of plants, but also has very important significance for realizin...
