Description

Technical Field

[0001] The present invention relates to the technical field of soil water detection and analysis, and in particular to an automatic sampling and monitoring device and a monitoring method for environmental soil water. Background Art

[0002] Analyzing the content of microorganisms, ammonia nitrogen, metal ions, etc. in soil water can determine the condition of soil water quality. Sampling water in soil is a frequently used method for environmental testing. Sampling devices are usually required to collect soil water. The collected water also needs to be properly filtered to remove large pieces of soil and various debris before water quality analysis and testing.

[0003] A more common method is to use sampling tubes, sampling bottles, etc. to collect moisture in the soil and then send it to the laboratory for analysis and testing. This method cannot provide continuous monitoring. There are also on-site tests using integrated test boxes. For example, China Utility Model Patent (CN212780797U) discloses an integrated box for monitoring water quality and soil, including a box body, which is divided into a water quality monitoring chamber and a soil detection chamber. A horizontal isolation plate is provided between the water quality detection chamber and the soil detection chamber. A motor is provided on one side of the horizontal isolation plate. The output end of the motor is connected to a rotating shaft. A connecting line is sleeved on the rotating shaft. One end of the connecting line is connected to a water quality probe, and the other end of the connecting line is connected to a water quality detector. A conical cylinder and a soil detector are provided in the soil detection chamber. A through groove is provided on the side wall of the conical cylinder near the lower end, and a soil sensor fixedly connected to the soil detector is fixedly connected in the through groove. The utility model monitors soil and water quality by on-site sampling and on-site testing. However, this equipment has requirements for the sampling environment and needs to be close to a water source so that water can be quickly obtained. In addition, when using this equipment, the detection personnel must always be nearby to operate it.

[0004] In addition, soil water in some environments requires a long time to sample and continuous monitoring, which places higher demands on the instruments and methods for outdoor soil water quality monitoring. Summary of the Invention

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] 18.

[0008] The monitoring sensor is connected to the monitoring body arranged in the monitoring and analysis box through a transmission line. The monitoring and analysis box is also provided with a power supply, a main controller and a communication module connected to the power supply, and the main controller is electrically connected to the communication module and the monitoring body respectively.

[0009] This environmental soil water automatic monitoring device can carry out long-term continuous water quality monitoring outdoors through the coordinated setting of the sampling rod and the monitoring and analysis box. The sampling rod can be inserted into the soil as a device for collecting water samples, and can also be used as a fixing device for connecting and supporting the monitoring and analysis box, maintaining the installation stability of the monitoring and analysis box, making it suitable for continuous outdoor use; using the settings of components such as the monitoring sensor, the main controller and the communication module, monitoring data can be uploaded and fed back in real time, which is convenient for experimenters to remotely obtain monitoring data without having to stay outdoors for a long time, thereby improving the convenience and effectiveness of monitoring.

[0018] Furthermore, the partition plate and the filter plate are respectively provided with insertion holes for the installation rod to pass through, and the insertion holes are all eccentrically arranged, and wiring holes are respectively provided near the insertion holes.

[0083] (4) The installed second rod 202 is docked with the first rod 201 , and the transmission line 12 is passed through the wiring channel 13 , and the first rod 201 and the second rod 202 are tightened.

[0084] The sampling rod using this assembly method is easy to operate and can be disassembled and used repeatedly. The components can be removed regularly for cleaning and maintenance and then assembled into the second rod body for long-term cyclic use.

[0085] Example 3:

[0086] A method for automatic sampling and monitoring of environmental soil water comprises the following steps:

[0087] (1) inserting a plurality of the sampling rods 2 into the environmental soil to be monitored, then installing the monitoring analysis box 1 on the plurality of the sampling rods 2, and connecting the transmission lines 12 to the corresponding monitoring bodies 16;

[0088] (2) Turn on the power supply 19 and control the door 15 to open the permeable grille through the mobile terminal connected to the master controller 17; at the same time, start the monitoring body 16 and the monitoring sensor 10 starts working;

[0089] (3) After confirming that the monitoring and analysis box 1 is securely fixed and the line connection and opening and closing are correct, the personnel can leave the site. The master controller 17 uploads the acquired monitoring data to the server in real time through the communication module. The server analyzes and processes the monitoring data and then feeds it back to the mobile terminal, remote access client, and water quality monitoring center. With this arrangement, the operator does not need to be outdoors for a long time, and the monitoring method can be used for continuous monitoring for up to ten hours or even multiple days. The slow and continuous collection function can also be used in situations where there is less moisture under the soil.

[0090] Example 4:

[0091] This embodiment provides a connection method for the first connecting rod.

[0092] like Figure 11 As shown, the first rod 201 is a multi-section, threaded rod. Each section has an internally threaded hole 30 at one end and an externally threaded connecting boss 31 at the other end. The connection between the connecting boss 31 and the internally threaded hole 30 facilitates the connection of multiple sections, allowing the length of the sampling rod to be adjusted for different soil layers and depths.

[0093] like Figure 12 As shown, a foldable solar panel 32 is also provided above the monitoring and analysis box 1. The solar panel 32 is connected to the power supply 19. The solar panel 32 can convert solar energy into electrical energy and store it in the power supply 19, thereby increasing the battery life and being conducive to long-term outdoor work use.

[0094] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
