Description

Technical Field

[0001] This utility model relates to soil monitoring equipment, specifically to a forest soil moisture monitoring device that is easy to assemble and disassemble. Background Technology

[0002] Forest soil moisture status is crucial to the health and stability of forest ecosystems, and accurate monitoring of soil moisture content can provide data support for forest water resource management and ecological protection. Currently, forest soil moisture information is monitored by inserting sensors on the ground. To ensure data accuracy, multiple sensors are often inserted at the same location. However, in practice, the following problems are often encountered: (1) it is difficult to ensure that multiple sensors are evenly spaced and at the same depth; (2) when measuring shallow soil, the sensors are prone to tilting or even falling over due to their shallow insertion depth, resulting in inaccurate monitoring data. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a forest soil moisture monitoring device that is easy to assemble and disassemble, which can ensure that multiple sensors are evenly spaced and at the same depth, and can achieve stable monitoring over a long period of time.

[0004] Technical Solution: This utility model discloses a forest soil moisture monitoring device that is easy to assemble and disassemble, comprising a connecting cover, a sensor for detecting soil moisture, and N combination plates; each combination plate has two splicing edges, the angle formed by the two splicing edges multiplied by N equals 360°; the N combination plates are spliced ​​together to form a complete sensor mounting plate; the two splicing edges of the combination plates have semi-circular notches, and the semi-circular notches of two adjacent combination plates form a cylindrical snap-fit, which is used to fit a groove around the top of the sensor for installation and fixation; the bottom of the sensor is rod-shaped; an arc-shaped plate is fixed to the top of the combination plate, the outer side of the arc-shaped plate has a threaded groove, the N arc-shaped plates are combined to form a ring, and the N threaded grooves form a complete external thread; a central column is fixed through the center of the connecting cover, the lower end of the central column being a conical tip; the connecting cover is installed by its internal thread engaging with the complete external thread, and the central column passes through the center of the sensor mounting plate.

[0005] Furthermore, the composite panels are fan-shaped, and N composite panels are spliced ​​together to form a disc shape.

[0006] Furthermore, the composite panel is in the shape of an isosceles triangle, and N composite panels are spliced ​​together to form a regular polygonal prism.

[0007] Furthermore, the tips formed by the two splicing edges of the composite panel are provided with fan-shaped notches, and the fan-shaped notches of the N composite panels form a central circular hole through which the central column passes.

[0008] Furthermore, the diameter of the central circular hole is equal to the diameter of the central column.

[0009] Furthermore, N is greater than or equal to 3.

[0010] Furthermore, matching protrusions and grooves are provided on the two end faces of the arc plate, and adjacent arc plates are connected and fitted together by the protrusions and grooves.

[0011] Beneficial effects: Compared with the prior art, this utility model has the following advantages:

[0012] This utility model has a modular structure, which is convenient for transportation and carrying, and is simple and convenient to assemble and disassemble.

[0013] When the central column is inserted into the soil, multiple sensors are evenly and symmetrically distributed around it, and all sensors are inserted to the same depth. When measuring shallow soil, the sensors support each other, increasing stability and preventing tilting or toppling, thus ensuring stable long-term monitoring. Furthermore, if foreign objects such as stones prevent a sensor from being inserted smoothly, that sensor can be removed without affecting the installation and monitoring of other sensors.

[0014] In summary, this utility model offers a good user experience, enabling stable soil moisture monitoring at equal intervals and depths over long periods, ensuring comprehensive and accurate monitoring of soil moisture in the monitored area, allowing for data comparison, and providing highly reliable monitoring results.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 5 As shown, this embodiment of the utility model provides a forest soil moisture monitoring device that is easy to assemble and disassemble, including a combination plate 1, a connecting cover 2, and a sensor 3. In this embodiment, the combination plate 1 is fan-shaped, and there are four of them. The two radii of the combination plate 1 are the splicing edges, and the central angle of the combination plate 1 is 90°. The four combination plates 1 can be spliced ​​together to form a disc-shaped sensor mounting plate.

[0019] Sensor 3 is used to detect soil moisture information. It has a cylindrical top and a rod-like bottom. The two splicing edges of the composite plate 1 have semi-circular notches. The semi-circular notches of two adjacent composite plates 1 form cylindrical snap-fit ​​slots 15, which are used to engage with the grooves 31 around the top of sensor 3 for installation and fixation. This snap-fit ​​installation method enables rapid positioning and installation of sensor 3.

[0020] An arc-shaped plate 11 is fixed to the top of the composite plate 1. The outer side of the arc-shaped plate 11 has a threaded groove 12. The four arc-shaped plates 11 are combined to form a ring shape, and the four threaded grooves 12 form a complete external thread. In order to ensure that the four arc-shaped plates 11 are stably combined together and facilitate assembly with the connecting cover 2, matching protrusions 13 and grooves 14 are respectively provided on the two end faces of the arc-shaped plates 11. Adjacent arc-shaped plates 11 are engaged with each other through the protrusions 13 and grooves 14.

[0021] A central column 21 is fixedly inserted into the center of the connecting cover 2, with a conical tip at its lower end. A fan-shaped notch 16 is formed at the tip of the two splicing edges of the composite plate 1, and the fan-shaped notches 16 of the four composite plates 1 form a central circular hole. The diameter of the central circular hole is equal to the diameter of the central column 21. The connecting cover 2 is installed using its internal thread and complete external thread, with the central column 21 passing through the central circular hole. This threaded connection allows for quick assembly and disassembly of the composite plate 1, connecting cover 2, and sensor 3. The central column 21 can be used for positioning, determining the central location area for soil moisture monitoring, and also ensures the overall stability of the monitoring device.

[0022] When the assembly plate 1, connecting cover 2, and sensor 3 are combined, the bottom of the central column 21 is lower than the bottom of the sensor 3. This allows the central column 21 to better secure the entire monitoring device, ensuring the accuracy of the data monitored by the sensor 3. If a sensor 3 cannot be inserted smoothly into the soil due to foreign objects such as stones, that sensor 3 can be removed (i.e., the corresponding bayonet 15 is left unattended) without affecting the installation and monitoring of other sensors 3. During insertion, the central column 21 can generally detect foreign objects before the sensor 3, thus indirectly protecting the sensor 3.
