Description

Technical Field

[0001] This invention belongs to the field of soil water analysis and detection technology, and in particular relates to an intelligent container-integrated soil water analyzer. Background Technology

[0002] Soil moisture refers to the suitable humidity level in the soil for vegetation growth. Soil moisture indicates the degree of dryness or wetness of the soil, also known as the actual water content of the soil. Specifically, it is expressed as a percentage of soil water content relative to field capacity or saturation water content. The Soil Moisture and Drought Management System complies with the latest "Soil Moisture Monitoring Standard SL364-2006, the People's Republic of China Water Resources Industry Standard." It can flexibly provide a stable and reliable optimal monitoring system according to user needs. Designed according to the requirements of the soil moisture monitoring standard, the system can not only monitor the most important parameter of soil moisture in real time, but also add probes according to user needs to monitor soil temperature, soil conductivity, soil pH, as well as air temperature and humidity, light intensity, wind speed and direction, carbon dioxide, rainfall, and other information. The accompanying software can flexibly set the sampling and storage cycle of moisture parameters, and perform functions such as patrol and recall data and data analysis according to user needs.

[0003] Currently, soil moisture sensors are widely used because, compared to methods such as drying, neutron method, time domain reflectometer method, and remote sensing, which are medium-energy methods that act on small areas and are somewhat destructive to the soil, soil moisture sensors not only solve the problem of the lack of soil moisture content detection technology in medium-sized areas, but also have the characteristics of accuracy, speed and convenience.

[0004] However, the soil moisture sensors currently in use require the analysis probe to be constantly moved on the ground to contact the soil in order to measure the soil moisture content. This is a time-consuming and labor-intensive task, which reduces the efficiency of soil water analysis in the region. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Example: Refer to Figures 1-4 A smart container integrated soil water analyzer includes:

[0045] The machine body 1 has rollers 2 rotating around it;

[0046] The control component includes a drive unit arranged on the body 1 and matched one-to-one with a plurality of rollers 2. The drive end of the drive unit is connected to the rollers 2. Any one of the rollers 2 can rotate in opposite directions along a first direction and a second direction through the drive unit, so that the body 1 has at least six degrees of freedom of movement.

[0047] Image acquisition device 3 is located at the front end of body 1 and is used to acquire ground exploration environment parameters. Image acquisition device 3 is communicatively connected to drive components.

[0048] The work frame 4 is arranged on the machine body 1 and is raised and lowered relative to the machine body 1. A pair of sampling plates 6 are movably connected to the work frame 4. The sampling plates 6 are configured to snap together to obtain soil samples.

[0049] The analytical probe 5 is movably mounted on the work frame 4. When the sampling plate 6 acquires a soil sample, the analytical probe 5 can be applied to the soil sample for analysis.

[0050] This technical solution utilizes rotating rollers 2 connected around the body 1 and controls these rollers 2 via a control component. A drive mechanism propels the rollers 2 to rotate along a first and second direction, achieving highly flexible drive control of the entire body 1. Furthermore, an image acquisition device 3 is installed at the front of the body 1 to acquire image information of the ground exploration environment parameters. This image acquisition device 3 is communicatively connected to the drive mechanism, improving the drive control effect of the body 1 and reducing manpower consumption. When the analysis probe 5 performs soil water analysis, it effectively improves operational efficiency. Additionally, the work frame 4 is movably connected to... A pair of sampling plates 6 are arranged opposite each other, allowing them to rise and fall relative to the machine body 1. Soil samples are collected by the snap-fitting of the sampling plates 6. An analysis probe 5 is set on the work frame 4. After the soil sample is collected, the analysis probe 5 is used directly for soil water analysis, improving the analysis efficiency. At the same time, since both the analysis probe 5 and the sampling plates 6 are set on the work frame 4, the relative movement between the analysis probe 5 and the sampling plates 6 is stably supported, improving the operation effect of soil sampling and water analysis, meeting the needs of intelligent integrated water analysis, and thus improving the efficiency and effectiveness of soil water analysis.

[0051] In this technical solution, the image acquisition device 3 is a common camera. After acquiring ambient light, it is converted into an electrical signal by a CCD. After being analyzed by the signal processing circuit, a two-dimensional digital signal is obtained. The two-dimensional digital signal is stored in the signal memory, thereby forming a mark of the ground exploration environment. This avoids the drive component from driving the roller 2 to move the body 1 to repeatedly pass through the same ground exploration route. The image acquisition device 3, in conjunction with the drive component, drives the body 1, effectively improving the efficiency of soil water analysis.

[0052] In this technical solution, the analytical probe 5 is a common detection probe in soil moisture meters. By using its detection end to contact the soil, the soil water can be analyzed.

[0053] Furthermore, it also includes:

[0054] The first control mechanism is set on the working frame 4 and has control terminals that are respectively connected to a pair of sampling plates 6. The pair of sampling plates 6 can move closer or further apart from each other through the first control mechanism and form an adjustable rotation angle relative to the working frame 4. When the machine body 1 is in the ground exploration position, the first control mechanism controls the pair of sampling plates 6 to obtain soil samples.

[0055] The limiting frame is slidably connected to the working frame 4. The working frame 4 is equipped with a first lifting component, and the lifting end of the first lifting component is connected to the limiting frame.

[0056] The second lifting component is installed on the machine body 1 and is configured to be connected to the work frame 4 so that the work frame 4 can be raised or lowered relative to the machine body 1;

[0057] The first control mechanism, the first lifting component, and the second lifting component are all connected to the image acquisition device 3 via communication.

[0058] By setting a first control mechanism on the work frame 4 to drive and control the sampling plate 6, a pair of sampling plates 6 can be adjusted to move closer or further apart from each other and form a rotation angle relative to the work frame 4. This makes it easier to control the sampling plate 6 to collect soil samples. Furthermore, since the sampling plate 6 collects soil by digging, the analysis probe 5 is prevented from directly contacting the ground. The sampling plate 6 loosens the soil and improves the service life of the analysis probe 5.

[0059] In addition, a first lifting component and a second lifting component are also provided on the body 1 to realize the drive control of the limit frame and the working frame 4 respectively. The first control mechanism, the second lifting component and the first lifting component are all connected to the image acquisition device 3 to realize the intelligent drive control of the whole soil water analyzer. Specifically, the control module in the image acquisition device 3 is connected to the signal receiving unit in each drive part to analyze the image signal and convert it into drive control electrical signal to realize the efficient operation of the whole water analyzer.

[0060] Furthermore, the first control mechanism includes:

[0061] The first servo motor 7 is fixedly connected to one side of the work frame 4. The bottom end of the work frame 4 is fixedly connected to the first mounting base 8. The first mounting base 8 is connected to the bidirectional lead screw 9. One end of the bidirectional lead screw 9 is fixedly connected to the output shaft of the first servo motor 7. A pair of first support plates 10 are threaded on the bidirectional lead screw 9. The first support plates 10 are connected to the sampling plate 6 one by one.

[0062] The first servo cylinder 11 is fixedly connected to a groove in the first support plate 10. The bottom end of the first support plate 10 is connected to the second support plate 12. The sampling plate 6 is fixedly connected to the bottom end of the second support plate 12. The side of the second support plate 12 near the first servo cylinder 11 is fixedly connected to the anti-protrusion 13. The first servo cylinder 11 and the anti-protrusion 13 cooperate to make the sampling plate 6 have an adjustable rotation angle relative to the working frame 4.

[0063] After the image signal is analyzed and processed by a computer or processor, the drive command is transmitted to the first servo motor 7 and the first servo cylinder 11 through the servo control system. After the machine body 1 moves to the ground-penetrating position, the first servo motor 7 rotates the bidirectional lead screw 9, which drives a pair of first support plates 10 to move in a direction that approaches each other. During the process, the sampling plate 6 slides in contact with the soil and moves in a direction that moves away from each other under the action of the soil. The first servo cylinder 11 abuts against the anti-protrusion 13, controlling the pair of sampling plates 6 to move closer to each other. Soil samples are collected when the pair of sampling plates 6 are engaged. Then, the analysis probe 5 is moved by the limit frame to contact the collected soil to realize soil analysis. The process can effectively avoid manpower consumption and avoid rigid contact between the analysis probe 5 and the soil, thus improving the analysis effect.

[0064] Furthermore, the sampling plate 6 has a semi-circular arc structure, and the bottom end of the sampling plate 6 is integrally formed with a sealing plate 14. When a pair of sampling plates 6 are fastened together, the two sealing plates 14 overlap.

[0065] By fixing the sealing plate 14 to the center of the sampling plate 6, and the sampling plate 6 having a semi-circular arc structure, after a pair of sampling plates 6 are fastened together, the two work together to form a container, and the baffle can be used to seal, thereby improving the sampling effect of soil samples.

[0066] Furthermore, the first lifting component includes:

[0067] The second servo motor 15 is fixedly connected to the work frame 4. The toothed plate 16 is fixedly connected to the side of the limit frame near the second servo motor 15, and the toothed plate 16 is distributed in the vertical direction.

[0068] Gear 17 is fixed to the output shaft of the second servo motor 15, and gear 17 meshes with gear plate 16.

[0069] The second servo motor 15 drives the gear 17 to rotate. The gear 17 meshes with the toothed plate 16 to control its sliding in the vertical direction. The toothed plate 16 is fixed to the limit frame, so that the limit frame can be raised and lowered in the vertical direction.

[0070] Furthermore, the limiting frame includes at least one pair of limiting plates 18, which are slidably connected to the working frame 4. A third support plate 19 is welded to the bottom of the pair of limiting plates 18. A limiting post 20 is fixedly connected to one side of the third support plate 19. The analysis probe 5 is fixedly connected to the limiting post 20 and is located above the middle of the pair of sampling plates 6 in the vertical direction. The limiting post 20 is slidably connected to the working frame 4.

[0071] The limiting post 20 is slidably connected to the working frame 4, and the analysis probe 5 is fixed on the limiting post 20, thereby improving the stability of the analysis probe 5 relative to the sampling plate 6.

[0072] Furthermore, the second lifting component includes:

[0073] A pair of second mounting seats 21 have limit grooves on their adjacent sides, and a sliding plate 22 is slidably connected in the limit groove. The working frame 4 is slidably connected between the pair of second mounting seats 21, and the two sides of the working frame 4 are respectively fixed to the two sliding plates 22.

[0074] The second servo cylinder 23 is fixedly connected in the limiting slide groove. The output end of the second servo cylinder 23 is fixedly connected to the slide plate 22. One end of the spring 24 is fixedly connected to the side of the slide plate 22 away from the second servo cylinder 23. The other end of the spring 24 is fixedly connected to the inner wall of the limiting slide groove.

[0075] The second servo cylinder 23 starts the slide plate 22 to slide along the limiting slide groove, thereby driving the working frame 4 to slide along the second mounting base 21, controlling the positional relationship between the sampling plate 6 and the soil, and the slide plate 22 and the limiting slide groove are elastically connected by the spring 24 to improve the stability of the slide plate 22 during the sliding process.

[0076] Furthermore, the driving components include:

[0077] The third servo motor 25 is fixed to the bottom of the machine body 1. It has the same number of rollers 2 and corresponds to each other. The output shaft of the third servo motor 25 is fixed to the drive shaft 26 through a coupling. The drive shaft 26 is rotatably connected to the machine body 1 through the bearing 27. The end of the drive shaft 26 away from the third servo motor 25 is fixed to the axis of the roller 2.

[0078] The third servo motor 25 is used to rotate the drive shaft 26, which controls the roller 2 to rotate forward and backward, so that the body 1 can be adjusted relative to the ground probe. The drive shaft 26 is connected to the body 1 by the bearing 27.

[0079] Furthermore, it also includes:

[0080] The controller 28, fixed to the body 1, is used for communication with the image acquisition device 3 and can process the image signals acquired by the image acquisition device 3 into electrical signals for servo drive control. It employs common computer components, etc.

[0081] Furthermore, it also includes:

[0082] The storage battery 29 is fixed on the body 1 and is used to connect to the image acquisition device 3 and the analysis probe 5 for power supply.

[0083] The working process of this embodiment is as follows:

[0084] The battery 29 powers the image acquisition device 3, the analysis probe 5, the first servo motor 7, the second servo motor 15, the third servo motor 25, the first servo cylinder 11, and the second servo cylinder 23, respectively, thereby increasing the overall duration of the intelligent water analysis operation. The controller 28 receives the image information acquired by the image acquisition device 3, processes it, and converts it into drive electrical signals. After controlling the rollers 2 to move the machine body 1 to the ground probe position, the controller analyzes and processes the image signals, transmitting the drive commands to the first servo motor 7 and the first servo cylinder 11 via the servo control system. As the machine body 1 moves... Upon reaching the exploration location, the first servo motor 7 rotates the bidirectional lead screw 9, driving a pair of first support plates 10 to move in a direction closer to each other. During this process, the sampling plate 6 slides in contact with the soil and moves away from each other under the action of the soil. The first servo cylinder 11 abuts against the anti-protrusion 13, controlling the pair of sampling plates 6 to move closer to each other. Soil samples are collected when the pair of sampling plates 6 are engaged. Then, the analysis probe 5 is moved by the limiting frame to contact the collected soil, realizing soil analysis. This process can effectively avoid manpower consumption and avoid rigid contact between the analysis probe 5 and the soil, thus improving the analysis effect.
