Description

Technical Field

[0001] This utility model relates to the field of humidity sensor technology, specifically to a monitoring probe structure for soil moisture monitoring. Background Technology

[0002] A soil moisture sensor is an electronic device used to measure the moisture content in soil. It is widely used in agriculture, horticulture, environmental monitoring, and water conservancy projects. It indirectly or directly reflects the soil moisture status by detecting changes in the physical or chemical properties of the soil.

[0003] A search revealed a Chinese patent, CN 221612860U, for a soil moisture monitoring probe structure, relating to the field of soil moisture monitoring technology. The probe includes a U-shaped base with a movable component at its lower end. This movable component includes a threaded cylinder with a first gear fixedly connected to its side wall. The first gear meshes with a second gear, and a motor is mounted on the upper end of the second gear. A monitoring component is located on the side wall of the threaded cylinder, including a protective tube threadedly connected to the side wall of the threaded cylinder. The protective tube has a first and a second mounting groove inside, and two mounting plates located within the first mounting groove. A spring is also present inside the protective tube, and the two mounting plates are fixedly connected to the two ends of the spring. In this invention, a wiping block removes soil from the probe surface, preventing prolonged contact between soil and the probe, reducing soil corrosion, and increasing the lifespan of the monitoring instrument.

[0004] Existing methods for monitoring soil moisture require inserting moisture sensors into the soil for extended periods to monitor soil moisture in real time. However, the soil surface is often dry and contains stones, which can damage the probe during initial insertion. Therefore, a new probe structure for soil moisture monitoring is needed to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a monitoring probe structure for soil moisture monitoring, comprising:

[0028] A humidity sensor, comprising a housing 10 and a monitoring probe 11, wherein the monitoring probe 11 is fixed at the lower end of the housing 10 and is evenly distributed;

[0029] The humidity sensor also includes a cable 12, which is fixed to the upper end of the housing 10;

[0030] The housing 10 serves a protective function and contains electronic components related to signal processing, power management, and communication. The monitoring probe 11 converts soil moisture content into an electrical signal through a moisture-sensitive material and transmits it to the circuit inside the housing 10. The cable 12 is used to transmit the signal.

[0031] The damage prevention component includes a connecting pipe 20, a tapered pipe 22, and an opening 23. The connecting pipe 20 is screwed to the outside of the housing 10, the tapered pipe 22 is fixed to the lower end of the connecting pipe 20, and the opening 23 is opened in the upper section of the tapered pipe 22 and is evenly distributed.

[0032] The damage prevention components also include heat dissipation holes 21 and reinforcing plates 24. The heat dissipation holes 21 are opened on the connecting pipe 20 and are evenly distributed. The reinforcing plates 24 are fixed to the inside of the tapered pipe 22 and are evenly distributed.

[0033] The upper end of the connecting pipe 20 is flush with the upper end of the housing 10, and the length of the connecting pipe 20 is longer than the length of the housing 10. The upper end of the reinforcing plate 24 is attached to the lower end of the housing 10.

[0034] The connecting pipe 20 serves as a connection, the heat dissipation hole 21 facilitates heat dissipation, the cone tube 22 facilitates insertion into the soil, and a small hole is opened at the bottom of the cone tube 22 to prevent water from accumulating inside the cone tube 22 and affecting the monitoring accuracy. The opening 23 facilitates the entry of soil into the cone tube 22, and the reinforcing plate 24 improves the strength of the cone tube 22.

[0035] Working principle:

[0036] Slide the connecting tube 20 from below the monitoring probe 11 upwards, and then screw the connecting tube 20 onto the housing 10. When in use, hold the connecting tube 20 and align the lower end of the cone tube 22 with the ground, insert it downwards until the cone tube 22 is inserted into the ground, and the soil enters the cone tube 22 through the opening 23. The soil moisture will be transferred from the external soil to the internal soil, and the monitoring probe 11 monitors the soil moisture in real time.

[0037] This step protects the monitoring probe 11 from damage caused by soil clumps when it is inserted into the soil.

[0038] Please see Figure 2 , Figure 4-5 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The support assembly includes a first connecting plate 30, a support arc plate 31, a second connecting plate 33, and a connecting shaft 34. The first connecting plate 30 is fixed to the upper end of the connecting pipe 20 and is evenly distributed. The second connecting plate 33 is fixed to the side of the support arc plate 31. The connecting shaft 34 is fixed between the two second connecting plates 33, and the first connecting plate 30 is sleeved on the connecting shaft 34.

[0040] The support assembly also includes torsion springs 35, which are respectively sleeved on both ends of the connecting shaft 34, with one end fixed on the side of the first connecting plate 30 and the other end fixed on the side of the second connecting plate 33.

[0041] The support assembly also includes a limiting arc plate 32 and a limiting ring 36. The limiting arc plate 32 is fixed to the upper end of the support arc plate 31, and the limiting ring 36 is screwed to the outside of the limiting arc plate 32.

[0042] The first connecting plate 30 and the second connecting plate 33 serve to connect the two. The connecting shaft 34 facilitates the rotation of the supporting arc plate 31. The supporting arc plate 31 provides support. The limiting arc plate 32 and the limiting ring 36 provide limiting. The torsion spring 35 has a reset function.

[0043] Working principle:

[0044] When not in use, the limiting ring 36 is screwed onto the limiting arc plate 32. At this time, the supporting arc plate 31 is wrapped around the opening 23 on the outside of the connecting pipe 20 and the tapered pipe 22. When in use, the limiting ring 36 is rotated to disengage it from the limiting arc plate 32. Under the action of the torsion spring 35, the connecting shaft 34 drives the second connecting plate 33 to rotate, which in turn drives the supporting arc plate 31 to rotate. The supporting arc plate 31 opens, allowing the tapered pipe 22 to be inserted into the soil. The supporting arc plate 31 is evenly distributed around the shell 10 and is located above the soil.

[0045] This step provides support for the housing 10, reducing the risk of the humidity sensor tipping over.
