Description

Technical Field

[0001] This utility model belongs to the field of soil monitoring technology, specifically relating to a portable soil water and fertilizer monitoring device. Background Technology

[0002] In the process of planting green manure in dryland areas, there is a significant competition for water and fertilizer resources between fallow crops and subsequent crops. In particular, the competitive use of soil moisture by fallow crops may cause insufficient water supply to affect the growth of subsequent crops, thereby threatening the goal of stable agricultural production. Real-time monitoring of soil moisture and nutrient dynamics in different areas through field experiments is a key means to optimize green manure planting patterns and coordinate water and fertilizer competition.

[0003] In field trials, to accurately capture the spatial heterogeneity of soil properties and compare the differences between different treatments, monitoring devices need to be deployed at multiple locations. However, existing soil monitoring devices mostly use integrated structures powered by solar panels, resulting in a large overall size and weight. In complex field environments, moving these devices requires frequent crossings of furrows and avoidance of plants, making transportation time-consuming and labor-intensive. This severely restricts the convenience of long-term monitoring at multiple locations, thereby affecting the efficiency and accuracy of soil data collection.

[0004] In view of this, the inventor has conducted in-depth research on the above-mentioned defects in the prior art and proposed a portable soil water and fertilizer monitoring device to solve the above problems, thus giving rise to this invention. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a portable soil water and fertilizer monitoring device to solve the problem that the existing soil monitoring devices, which use solar panels for power supply, are too large and heavy to be portable.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] A portable soil water and fertilizer monitoring device includes a housing. A first through-slot is formed at the top of the housing. Slide rails are fixedly installed on both side walls of the first through-slot. A tension assembly is slidably mounted on the slide rails. The tension assembly includes a telescopic rod, a first connecting rod, a second connecting rod, and a mounting rod. The telescopic rod is slidably mounted on the slide rails. A support is fixedly installed at the end of the telescopic rod away from the slide rails. One end of the first connecting rod is hinged to the support, and the other end is hinged to the second connecting rod. The other end of the second connecting rod is hinged to the mounting rod. A rotating shaft is rotatably mounted at the top of the housing, and a flexible solar panel is wound around the rotating shaft. The flexible solar panel is fixedly connected to the mounting rod. A support rod and a ratchet are rotatably mounted on the top of the housing. The support rod and the ratchet are coaxially arranged. A pawl is slidably mounted on the top of the housing. The ratchet matches the pawl. A hook is provided at the end of the support rod. A pull ring is provided at the top of the mounting rod. The hook matches the pull ring. A battery and a soil monitor are provided inside the housing. The soil monitor is slidably mounted inside the housing. The battery is electrically connected to the flexible solar panel. The soil monitor is electrically connected to the battery. A detection hole is provided at the bottom of the housing. The detection hole matches the probe of the soil monitor.

[0008] Based on the above technical solution, the present invention has made the following improvements:

[0009] Furthermore, the housing is equipped with a positioning frame, with fixing rods at each of its four corners. A second through-slot is formed on the side wall of the housing, within which a slider is slidably installed and fixedly connected to the positioning frame. Positioning holes are located at the four corners of the bottom of the housing, matching the fixing rods. The positioning frame is positioned above the soil monitor, and a spring connects the soil monitor to the bottom surface of the housing. By pressing down on the slider, the positioning frame and fixing rods inside the housing slide downwards synchronously. The fixing rods pass through the positioning holes on the housing and insert into the soil, thus securing the equipment and effectively enhancing its wind and impact resistance. Because the positioning frame is above the soil monitor, its downward movement also moves the soil monitor downwards, allowing the probe of the soil monitor to insert into the soil and detect parameters such as soil moisture and nutrients. Moreover, since the positioning frame is above the soil monitor, the fixing rods insert into the soil before the probes, preventing the probes from bending or breaking due to device displacement during insertion.

[0010] Furthermore, the two side walls of the second channel are elastically connected to limit blocks by elastic elements; this structural design prevents the positioning frame from moving inside the box when carried or moved.

[0011] Furthermore, a wireless data transmission system is fixedly installed inside the enclosure. This system is electrically connected to both the battery and the soil monitoring instrument. By wirelessly transmitting the data detected by the soil monitoring instrument through the wireless data transmission system, and providing real-time feedback, researchers can dynamically monitor changes in parameters such as soil moisture and nutrients, avoiding the lag of manual inspections. The accompanying threshold warning function can trigger an alarm immediately when data is abnormal, helping researchers respond quickly to emergencies in the field and effectively improving the efficiency of scientific data collection and the timeliness of decision-making.

[0012] Furthermore, the top of the container is equipped with a handle, and the base is equipped with wheels. This structural design allows for flexible handling of complex terrain such as field furrows, enabling easy lifting and smooth movement, significantly reducing physical exertion during transport. This allows researchers or operators to easily transfer the device, greatly improving the efficiency and comfort of field monitoring work, and ensuring that the equipment combines flexibility and ease of use during long-term field monitoring.

[0013] Furthermore, a rocker arm is fixedly installed at one end of the rotating shaft, and the rocker arm passes through the housing; shaking the rocker arm allows the flexible solar panel to be rewound. This structural design is simple and practical.

[0014] Compared with the prior art, the portable soil water and fertilizer monitoring device disclosed in this utility model replaces the external fixed structure of the traditional rigid solar panel by winding a flexible solar panel around the internal shaft of the box. In the rolled-up state, the overall volume of the device is greatly reduced, and the flexible material reduces the weight of the device. This allows the solar panel to be completely stored in the box during transportation, which significantly improves the problem of inconvenience in handling caused by the external solar panel of the traditional device, which is too large and heavy. This meets the actual needs of field operations for equipment portability. At the same time, by rotating the support rod, it is easy to adjust the flexible solar panel to a suitable position to absorb sunlight for energy storage. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 6As shown, a portable soil water and fertilizer monitoring device includes a housing 1. A first through-slot 2 is formed at the top of the housing 1. Slide rails 3 are fixedly installed on both sides of the first through-slot 2. A tensioning assembly is slidably installed on the slide rails. The tensioning assembly includes a telescopic rod 4, a first connecting rod 6, a second connecting rod 7, and a mounting rod 8. The telescopic rod 4 is slidably installed on the slide rail 3. A support 5 is fixedly installed at the end of the telescopic rod 4 away from the slide rail 3. One end of the first connecting rod 6 is hinged to the support 5, and the other end is hinged to the second connecting rod 7. The other end of the second connecting rod 7 is hinged to the mounting rod 8. A rotating shaft 9 is rotatably installed at the top of the housing 1. A flexible solar panel 10 is wound around the rotating shaft 9. The support rod 11 and ratchet 12 are rotatably mounted on the top of the housing 1, and the support rod 11 and ratchet 12 are coaxially arranged. A pawl 13 is slidably mounted on the top of the housing 1, and the ratchet 12 matches the pawl 13. A hook 111 is provided at the end of the support rod 11, and a pull ring 81 is provided at the top of the mounting rod 8. The hook 111 matches the pull ring 81. A battery 14 and a soil monitor are provided inside the housing 1. The soil monitor 15 is slidably mounted inside the housing 1. The battery 14 is electrically connected to the flexible solar panel 10, and the soil monitor 15 is electrically connected to the battery 14. A detection hole 16 is provided at the bottom of the housing 1, and the detection hole 16 matches the probe of the soil monitor. Pulling the pull ring 81 pulls the telescopic rod 4 to the top of the slide rail 3. Then the telescopic rod 4 pops out and locks at the top of the slide rail 3. Continue pulling the pull ring 81, and the first connecting rod 6, which is hinged to the support 5, and the second connecting rod 7, which is hinged to the first connecting rod 6, are both pulled from the horizontal position to the vertical position. The flexible solar panel 10 is then pulled out and unfolded. Then the pull ring 81 is connected to the pull hook 111. Rotate the support rod 11 to adjust the position of the flexible solar panel 10 facing the light. After the adjustment is completed, slide the pawl 13 to lock the ratchet 12 to fix the adjusted position. Then insert the soil monitoring instrument into the soil to test the soil.

[0025] Specifically, the housing 1 is equipped with a positioning frame 17 inside, and a fixing rod 18 is provided at each of the four corners of the positioning frame 17. A second through groove 19 is opened on the side wall of the housing 1, and a slider 20 is slidably installed in the second through groove 19. The slider 20 is fixedly connected to the positioning frame 17. Positioning holes 21 are opened at the four corners of the bottom of the housing 1. The positioning holes 21 match the fixing rods 18. The positioning frame 17 is located above the soil monitor 15. A spring 22 is connected between the soil monitor 15 and the bottom surface of the housing 1. By stepping down on the slider 20, the positioning frame 17 and the fixing rods 18 inside the housing 1 slide down synchronously. The fixing rods 18 pass through the positioning holes 21 on the housing 1 and insert into the soil, thus fixing the equipment and effectively enhancing the equipment's wind and impact resistance. Since the positioning frame 17 is located above the soil monitor 15, as the positioning frame 17 moves downward, it drives the soil monitor 15 to move downward, allowing the probe of the soil monitor 15 to be inserted into the soil to detect parameters such as soil moisture and nutrients. Furthermore, since the positioning frame 17 is located above the soil monitor 15, the fixing rod 18 will be inserted into the soil before the probe, thus avoiding the probe bending or even breaking due to device displacement when the probe is inserted.

[0026] Specifically, the two side walls of the second channel 19 are elastically connected to the limit block 23 by elastic elements; this structural design prevents the positioning frame 17 from moving inside the box 1 when carried or moved.

[0027] Specifically, a wireless data transmission system 24 is fixedly installed inside the housing 1. The wireless data transmission system 24 is electrically connected to the battery 14 and the soil monitoring instrument 15. By setting up the wireless data transmission system 24 to wirelessly transmit the data detected by the soil monitoring instrument 15 and provide real-time feedback, researchers can dynamically monitor changes in parameters such as soil moisture and nutrients, avoiding the lag of manual inspection. The supporting threshold warning function can trigger an alarm immediately when the data is abnormal, helping researchers to respond quickly to sudden situations in the field and effectively improve the efficiency of scientific data collection and the timeliness of decision-making.

[0028] Specifically, the top of the housing 1 is equipped with a handle 25, and the base of the housing 1 is equipped with wheels 26. This structural design can flexibly cope with the complex terrain of field furrows, allowing for easy lifting and smooth movement, significantly reducing physical exertion during transportation. This enables researchers or operators to easily transfer the device, greatly improving the efficiency and comfort of field monitoring work, and ensuring that the equipment combines flexibility and ease of use during long-term field monitoring.

[0029] Specifically, a rocker arm 27 is fixedly installed at one end of the rotating shaft 9, and the rocker arm 27 passes through the housing 1; by rocking the rocker arm 27, the flexible solar panel 10 can be rewound. This structural design is simple and practical, and improves the convenience of the device.

[0030] The method of using this utility model is as follows: transport the device to the location via rollers 26 and handles 25, then rotate the box 1 to adjust its orientation to facilitate subsequent adjustment of the light-facing position of the flexible solar panel 10, then step on the slider 20, and the slider 20 slides along the second through groove 19 to the bottom, causing the positioning frame 17 and the fixing rod 18 inside the box 1, which are fixedly connected to it, to slide down synchronously. The fixing rod 18 passes through the positioning hole 21 on the box 1 and inserts into the soil. While the positioning frame 17 moves down, it drives the soil monitoring instrument to move down, so that the probe of the soil monitoring instrument is inserted into the soil through the detection hole 16. Then, pull the ring 81 to pull the telescopic rod 4 to the top of the slide rail 3. The telescopic rod 4 then pops out and locks into the top of the slide rail 3. Continue to pull the ring 81, and the first connecting rod 6, which is hinged to the support 5, and the second connecting rod 7, which is hinged to the first connecting rod 6, are both pulled from the horizontal position to the vertical position. The flexible solar panel 10 is then pulled out and unfolded. Then, the ring 81 is connected to the hook 111. Rotate the support rod 11 to adjust the position of the flexible solar panel 10 facing the light. After the adjustment is completed, slide the pawl 13 to lock the ratchet 12 to fix the adjusted position. Then, insert the soil monitoring instrument into the soil to test the soil.
