Description

Technical Field

[0001] This utility model relates to the field of observation device technology, specifically to an unattended in-situ root observation window. Background Technology

[0002] Plant roots are embedded in the soil, making it difficult to dynamically understand their production, senescence, and death processes. A key challenge in root ecology research is how to obtain dynamic root growth data through continuous in-situ observation without affecting the plant's growth in the field or damaging root morphology. In the field, methods for in-situ observation of plant roots are very limited; microtube and in-situ root window methods are currently the two most commonly used methods for studying fine root dynamics.

[0003] However, due to the small effective observation window area of ​​micro-root canals, it is impossible to observe the complete branching level or functional type of the root (such as absorptive roots and transport roots). Although the in-situ root window method has a larger observation window area, the cover plate needs to be lifted for each scan, which significantly disturbs the root growth environment. In addition, both micro-root canal and in-situ root window methods require manual image acquisition, which is time-consuming, labor-intensive, and has long intervals, making it impossible to capture the dynamic development of the root system at high temporal resolution. Existing sealed automatic root boxes based on root window technology can achieve real-time acquisition, but they are expensive, making it difficult to achieve high-density, large-scale deployment; moreover, they are buried deep underground, making maintenance difficult, and once the automatic image acquisition fails, there is no way to remedy the situation. Utility Model Content

[0004] The purpose of this invention is to provide an unattended in-situ root observation window to solve the problems mentioned in the background art, such as the limited observation effect due to the small effective observation window area of ​​microroot canals, the impact on the growth environment of plant roots during observation, the time and labor-intensive nature of manual observation, the inability to capture the complete dynamics of root development, and the difficulty in maintenance due to deep burial.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an unattended in-situ root observation window, comprising an observation plate and a support, wherein the observation plate and the support are provided with a connecting component for assembly, the connecting component includes protrusions on both sides of the observation plate, each of the two protrusions having a plurality of mating holes on one side, the observation plate having a support on both sides, the support having a support rod on the outside of the support, and the support having a slot on the side near the observation plate;

[0006] The slot has multiple cavities on its inner wall, and each cavity contains a connecting rod. The outer wall of the connecting rod is provided with a spring. One end of the connecting rod is provided with a handle, and the other end is provided with a top block. A square tube is provided between the two brackets, and the top of the square tube is provided with a mounting hole.

[0007] Preferably, the two supports are distributed on both sides of the observation plate. The supports are L-shaped, and the two ends of the support rod are connected to the two sides of the support respectively, forming a triangular structure with the support.

[0008] Preferably, one side of the protrusion is connected to the outer wall of the observation plate, and the other side is inserted into the slot of the bracket via a bracket and slidably connected to the inner wall of the slot.

[0009] Preferably, the plurality of cavity arrays are distributed on the inner wall of the slot, and when the protrusion is embedded in the slot, they correspond to and communicate with the mating holes on the outer wall of the protrusion.

[0010] Preferably, the connecting rod is located inside the cavity and is slidably connected to the inner wall of the cavity. One end of the connecting rod extends to the outside and is connected to the handle, while the other end is embedded in the slot and connected to the top block. The spring is located inside the cavity, and its two ends are respectively connected to the inner wall of the cavity and the outside of the connecting rod.

[0011] Preferably, the square tube is placed between two supports, and both ends extend to the top of the two supports respectively and are connected to the supports by bolts. The central area of ​​the top of the square tube has a reserved mounting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using acrylic material to make the observation plate, the corrosion resistance and moisture resistance of the observation plate can be improved, and the service life can be extended.

At the same time, the stability of the observation plate can be improved by using a bracket. The bracket and the observation plate can be connected by plug-in method, which facilitates assembly and disassembly, improves the convenience of operation, and is reusable. Furthermore, the modular structure eliminates the need for a dedicated data acquisition and wireless transmission device.

[0014] 2. By installing square tubes on the outside of the bracket and reserving mounting holes at the top of the square tubes, high-definition cameras and flatbed scanners can be installed. This achieves high temporal resolution and high-quality time-series images, while acquiring images of different resolutions to meet the needs of different observation objects. It also allows for convenient manual remedial measures in case of unattended data acquisition failures.

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.

[0022] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0023] Please see Figures 1-3 An unattended in-situ root observation window includes an observation plate 1 and a support 3. The observation plate 1 and the support 3 are internally equipped with connecting components for assembly. These connecting components include protrusions 2 on both sides of the observation plate 1. The protrusions 2 can be inserted into slots 4 on the inner wall of the support 3 during assembly, thereby positioning the observation plate 1 and the support 3 at an angle during installation. Each of the two protrusions 2 has multiple mating holes 201 on one side, which correspond to cavities 5 in the slots 4 of the support 3. Supports 3 are provided on both sides of the observation plate 1, and can be connected to the observation plate 1 for support and fixation. Support rods 301 are provided on the outside of the support 3, connecting to the side frames of the support 3 to form a triangular structure, improving overall stability. Slots 4 are provided on the side of the support 3 closest to the observation plate 1.

[0024] Two supports 3 are distributed on both sides of the observation plate 1. The supports 3 are L-shaped structures, and the two ends of the support rod 301 are connected to the two sides of the support 3 respectively, forming a triangular structure with the support 3. One side of the protrusion 2 is connected to the outer wall of the observation plate 1, and the other side is inserted into the slot 4 of the support 3 through the support 3 and is slidably connected to the inner wall of the slot 4.

[0025] Specifically: Observation plate 1 is made of acrylic material and has six neatly arranged square grids inside for easy observation. The oblique openings and root window openings of the support 3 are fitted with covers made of double-sided aluminum foil-coated insulating pearl cotton. During use, the protrusions 2 on both sides of observation plate 1 are inserted into the slots 4 inside the support 3, ensuring the mating holes 201 on the outside of the protrusions 2 correspond and communicate with the cavities 5 on the inner wall of the slots 4. This assembles observation plate 1 and support 3. Then, the frame of observation plate 1 is placed parallel and tightly against one side of the prepared soil profile. The frame is compacted, ensuring the soil is densely filled behind the entire transparent acrylic plate, with no gaps between the plate and the soil profile.

[0026] Please see Figures 2-4 The inner wall of the slot 4 is provided with multiple cavities 5 for housing the connecting rod 502 and positioning the angle of the connecting rod 502 when it slides. The connecting rod 502 is provided inside each of the multiple cavities 5. The two ends of the connecting rod 502 are connected to the handle 503 and the top block 6 respectively, and they are linked together. The outer wall of the connecting rod 502 is provided with a spring 501, which is used to support the connecting rod 502 and push the connecting rod 502 to slide in the cavity 5. One end of the connecting rod 502 is provided with a handle 503, which facilitates the movement of the connecting rod 502 in the multiple cavities 5. The other end is provided with a top block 6, which can move with the connecting rod 502 and extend into the slot 4. When the protrusion 2 is located in the slot 4, it is inserted into the docking hole 201 on the outside of the protrusion 2. A square tube 7 is provided between the two brackets 3. The top of the square tube 7 is provided with a mounting hole 701.

[0027] Multiple cavities 5 are arrayed on the inner wall of slot 4, and when the protrusion 2 is embedded in slot 4, they correspond to and communicate with the docking holes 201 on the outer wall of the protrusion 2. The connecting rod 502 is located in the cavity 5 and is slidably connected to the inner wall of the cavity 5. One end of the connecting rod 502 extends to the outside and is connected to the handle 503, and the other end is embedded in slot 4 and is connected to the top block 6. The spring 501 is located in the cavity 5, and its two ends are respectively connected to the inner wall of the cavity 5 and the outside of the connecting rod 502. The square tube 7 is placed between two supports 3, and its two ends extend to the top of the two supports 3 and are connected to the supports 3 by bolts. The central area of ​​the top of the square tube 7 has a reserved mounting hole 701.

[0028] Specifically: When connecting the observation plate 1 to the bracket 3, the handle 503 needs to be pulled, and the connecting rod 502 needs to be used to drive the top block 6 to retract into the cavity 5, away from the slot 4, so that the protrusion 2 can smoothly enter the slot 4. After the protrusion 2 and the slot 4 of the bracket 3 are properly inserted, the handle 503 is released. The spring 501 in the cavity 5 pushes the connecting rod 502 to slide in the cavity 5, and drives the top block 6 to insert into the mating hole 201 on the outer wall of the protrusion 2, thereby fixing the observation plate 1 and the bracket 3. After assembly, the square tube 7 is passed horizontally between the two brackets 3, and the square tube 7 is connected to the bracket 3 with bolts. Then, the high-definition camera is installed on the square tube 7. At the same time, a flatbed scanner is carried when the equipment is used. The high-definition camera and scanner can improve the in-situ root system data collection. The high-definition camera is used to acquire root system images. The system is set to collect time-series images daily, and the images are automatically saved in memory and automatically uploaded to FTP via 4G network. The images are downloaded periodically for unattended collection.

[0029] When the camera detects abnormal growth events or when it is necessary to observe the microstructure of the root surface, a flatbed scanner is used to acquire images of the root system. During operation, remove the pearl cotton cover plate on the beveled edge of the outer frame, and wipe the outer surface of the transparent frame wall (acrylic panel) clean, ensuring there is no dirt, moisture, or soil residue obstructing the view. Place the scanning surface of the flatbed scanner firmly against the cleaned outer surface of the transparent frame wall and perform the scan.

[0030] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
