Description

Technical Field

[0001] This utility model belongs to the technical field of plant canopy analysis equipment, and specifically relates to a plant canopy analyzer. Background Technology

[0002] A plant canopy analyzer is a professional instrument used to accurately measure and analyze the structure and light energy utilization of plant canopies. It is widely used in agricultural research, ecological monitoring and forestry management, and generally has a rod-shaped collection module and a main unit module.

[0003] In current plant physiology and agricultural and forestry research, plant canopy analyzers are important tools for analyzing canopy structure and light interception.

[0004] However, most existing canopy analyzers have a simple rod-shaped structure, requiring operators to hold the instrument by hand and keep it stable throughout the process. When performing large-area or long-term canopy scans, the continuous tension in the arm muscles can easily lead to fatigue and tremors, which seriously affects the accuracy and consistency of data acquisition.

[0005] In addition, existing equipment typically has its line interface located at the end of the instrument. Placing it vertically directly will compress the connecting cable, causing the interface to loosen or the cable to be damaged. Placing it flat may cause the sensitive probe to come into contact with the ground, resulting in contamination or impact. This dilemma forces operators to frequently plug and unplug cables, which not only accelerates interface wear but may also affect the lifespan of the instrument due to frequent power on and off. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plant canopy analyzer.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a plant canopy analyzer, comprising a collection body, a connecting line being snapped onto one end of the collection body, a main unit module being snapped onto one end of the connecting line, an anti-slip rubber ring being glued to the collection body near the connecting line, and shafts being symmetrically rotatably connected to both sides of the collection body near the connecting line. A bent rod is snapped onto one end of each shaft, a proximal pad is snapped onto the two bent rods near the shaft, and a distal pad is snapped onto the two bent rods away from the shaft. The proximal pad is concave in shape, and the distal pad is convex in shape. A positioning module is provided at the shaft, and a support module is provided at the end of the bent rod away from the shaft.

[0008] Preferably, the positioning module includes: a semi-circular component, which is fixed to the collecting body near the shaft; an arc groove, wherein multiple arc grooves are arranged in a circumferential array on the inner circumferential surface of the semi-circular component; and an arc plate, both ends of which are fixed to the circumferential surface of the shaft, and the circumferential surface of the arc plate is nested within the inner wall of an arc groove.

[0009] Preferably, an L-shaped hook is fixed to the side of the collecting body near the distal end of the hand pad.

[0010] Preferably, the support module includes: a shaft protrusion, one end of which is fixed to one side of the bent rod; a support plate, the inner wall of which is rotatably connected to both ends of the shaft protrusion; a fixing groove, which is formed on the side of the support plate near the bent rod; an L-shaped fastener, the surface of which is slidably connected to the inner wall of the bent rod; a control button, one end of which is fixed to one end of the parallel section of the L-shaped fastener, and the circumferential surface of which is slidably connected to the inner wall of the bent rod; and a return spring, one end of which is fixed to the other end of the parallel section of the L-shaped fastener.

[0011] Preferably, a limit post is fixed to one end of the L-shaped fastener near the return spring, and a limit hole is formed on the inner wall of the bent rod near the L-shaped fastener, with the inner wall of the limit hole slidingly connected to the circumferential surface of the limit post.

[0012] Preferably, one edge of the vertical section of the L-shaped fastener is configured as an auxiliary bevel.

[0013] Preferably, the collecting body has end pads symmetrically glued to one end near the connecting line, and the thickness of the end pads is greater than the diameter of the connecting line.

[0014] Preferably, the end pad has a wire-holding groove in the middle, and the inner wall of the wire-holding groove is in contact with the circumferential surface of the connecting wire.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model provides additional support points for the operator by symmetrically arranging curved rods that can rotate around the shaft on both sides of the collecting body, and setting proximal and distal pads on the curved rods. The operator's forearm can be supported by the curved rods and pads, distributing some of the instrument weight to the arm, which significantly reduces hand and forearm muscle fatigue caused by prolonged holding, effectively suppresses instrument shaking caused by fatigue tremors, and thus ensures the accuracy and consistency of data acquisition during coronal scanning.

[0017] 2. This utility model, through the support module set at the far end of the curved rod, allows the support plate to be unfolded to form a triangular support structure with the curved rod when the instrument needs to be temporarily placed, stably tilting and supporting the collecting body on the ground; when the support plate is not needed, the operator rotates the support plate so that it contacts the L-shaped fixing piece. Due to the auxiliary inclined surface design of the L-shaped fixing piece, the L-shaped fixing piece is pushed by the support plate and automatically snaps into the fixing groove under the action of the return spring to lock the support state. This tilting placement method avoids the connection interface at the end of the collecting body being directly pressured and also prevents the sensitive probe from contacting the ground, effectively solving the problems of traditional rod-shaped instruments pressing on the cable when placed vertically and easily contaminating and damaging the probe when placed flat.

[0018] 3. This utility model, through the cooperation of the semi-circular part of the positioning module, the embedded arc groove and the embedded arc piece on the shaft, allows the bent rod to be adjusted to multiple preset angles relative to the collecting body and reliably positioned, adapting to the usage habits and working postures of different operators, and can be used to form storage or support by adjusting the preset angle.

[0019] 4. This utility model provides buffer protection and cable guide for the connecting wire by setting the end rubber pad and the cable clamping groove at the end of the collecting body, which reduces the bending and stress concentration of the cable at the interface, reduces the risk of interface loosening and wire damage, and helps to fix the connecting wire and prevent it from becoming messy.

[0020] 5. This utility model further enhances the stability of handheld use and the convenience of temporary hanging by using anti-slip rubber rings and L-shaped hooks. When the curved rod rotates to fit tightly against the collection body, the operator can apply a little force to deform the distal end pad and make it fit against the inner surface of the L-shaped hook, thereby assisting the positioning module in storing and positioning the curved rod, preventing the curved rod from rotating during transportation when not in use, and improving the stability of the equipment.

[0039] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0040] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0041] Example 1:

[0042] refer to Figures 1-8A plant canopy analyzer includes a collection body 1, with a connecting line 101 snapped onto one end of the collection body 1 and a main unit module 102 snapped onto the other end of the connecting line 101. An anti-slip rubber ring 204 is glued to the collection body 1 near the connecting line 101. Shafts 203 are symmetrically rotatably connected to both sides of the collection body 1 near the connecting line 101. A bent rod 2 is snapped onto one end of the shaft 203. A proximal pad 201 is snapped onto the two bent rods 2 near the shaft 203, and a distal pad 202 is snapped onto the two bent rods 2 away from the shaft 203. The proximal pad 201 is concave in shape, and the distal pad 202 is convex in shape. A positioning module 3 is provided at the shaft 203, and a support module 5 is provided at the end of the bent rod 2 away from the shaft 203.

[0043] Specifically, by symmetrically arranging curved rods 2 that can rotate around the shaft 203 on both sides of the collection body 1, and by setting proximal pads 201 and distal pads 202 on the curved rods 2, an additional support structure is provided for the operator. The concave design of the proximal pad 201 fits the proximal end of the forearm, and the convex design of the distal pad 202 adapts to the curve of the distal end of the forearm, so that the operator's forearm can be supported by the curved rods 2 and the pads, distributing some of the instrument weight to the arm, significantly reducing hand and forearm muscle fatigue caused by prolonged holding, and effectively suppressing instrument shaking caused by fatigue tremors, thereby ensuring the accuracy and consistency of data acquisition during coronal scanning.

[0044] The positioning module 3 includes: a semi-circular part 301, which is fixed to the collecting body 1 near the shaft 203; an arc groove 302, in which multiple arc grooves 302 are arranged in a circular array on the inner circumferential surface of the semi-circular part 301; and an arc piece 303, both ends of which are fixed to the circumferential surface of the shaft 203, and the circumferential surface of the arc piece 303 is nested with the inner wall of an arc groove 302.

[0045] Specifically, through the cooperation of the semi-circular part 301 of the positioning module 3, the arc grooves 302 formed by the circumferential array on its inner circumference, and the arc plate 303 fixed to the circumference of the shaft part 203, the bent rod 2 can be adjusted at multiple preset angles relative to the collecting body 1. The nesting of the arc plate 303 with different arc grooves 302 provides reliable positioning, adapts to the usage habits and working postures of different operators, and can stabilize the bent rod 2 in specific positions such as storage or support.

[0046] An L-shaped hook 4 is fixed on one side of the main body 1 near the distal end pad 202.

[0047] Specifically, by fixing an L-shaped hook 4 to the side of the collecting body 1 near the distal hand pad 202, the instrument is provided with temporary suspension convenience. When the bent rod 2 is rotated to fit tightly against the collecting body 1 for storage, the distal hand pad 202 can be slightly deformed by applying force and fit against the inner surface of the L-shaped hook 4 to form auxiliary positioning, preventing the bent rod 2 from accidentally rotating and unfolding during transportation when not in use, thereby improving the carrying stability and storage reliability of the equipment.

[0048] The support module 5 includes: a shaft protrusion 501, one end of which is fixed to one side of the bent rod 2; a support plate 502, the inner wall of which is rotatably connected to both ends of the shaft protrusion 501; a fixing groove 503, which is formed on the side of the support plate 502 near the bent rod 2; an L-shaped fastener 504, the surface of which is slidably connected to the inner wall of the bent rod 2; a control button 505, one end of which is fixed to one end of the parallel section of the L-shaped fastener 504, and the circumferential surface of which is slidably connected to the inner wall of the bent rod 2; and a return spring 506, one end of which is fixed to the other end of the parallel section of the L-shaped fastener 504.

[0049] Specifically, through the cooperation of the shaft protrusion 501, support plate 502, fixing groove 503, L-shaped fixing member 504, control button 505 and reset spring 506 of the support module 5, the unfolding and locking functions of the support plate 502 are realized. After unfolding, the support plate 502 and the bent rod 2 form a triangular support structure. The bent rod 2, through rotation, forms a triangular support structure with the collecting body 1, which can stably tilt and support the collecting body 1 on the ground, avoiding pressure on the end connection line 101 interface and contact of the sensitive probe with the ground. When unfolding is required, the operator only needs to press the control button 505 inward to unlock the L-shaped fixing member 504 and the support plate 502.

[0050] One end of the L-shaped fastener 504 near the return spring 506 is fixed with a limit post 6. A limit hole 601 is opened on the inner wall of the bent rod 2 near the L-shaped fastener 504. The inner wall of the limit hole 601 is slidably connected to the circumference of the limit post 6.

[0051] Specifically, the sliding engagement between the limiting post 6 on the L-shaped fastener 504 and the limiting hole 601 on the inner wall of the bent rod 2 restricts the sliding stroke of the L-shaped fastener 504, preventing it from moving excessively or coming out of the bent rod 2, thus ensuring the reliable operation of the support locking mechanism.

[0052] The vertical section edge of the L-shaped fastener 504 is set as an auxiliary bevel 7.

[0053] Specifically, by setting one edge of the vertical section of the L-shaped fastener 504 as an auxiliary inclined surface 7, when the rotating support plate 502 is moved to the storage position, the support plate 502 can smoothly press the auxiliary inclined surface 7 and push the L-shaped fastener 504 backward. After the support plate 502 is in place, the L-shaped fastener 504 automatically engages with its fixing groove 503 under the action of the return spring 506 to achieve locking, thus simplifying the storage operation.

[0054] The collecting body 1 has end pads 8 symmetrically glued to one end near the connecting line 101. The thickness of the end pads 8 is greater than the diameter of the connecting line 101.

[0055] The end pad 8 has a wire-locking groove 9 in the middle, and the inner wall of the wire-locking groove 9 is in contact with the circumference of the connecting wire 101.

[0056] Specifically, by symmetrically gluing and fixing end pads 8 at one end of the collecting body 1 near the connecting line 101, and making the thickness of the end pads 8 greater than the diameter of the connecting line 101, buffer protection is provided for the end of the instrument. When the instrument is placed at an angle, the end pads 8 contact the support surface before the interface of the connecting line 101, effectively avoiding loosening or damage caused by direct pressure on the interface. By opening a wire-holding groove 9 in the middle of the end pads 8, the circumference of the connecting line 101 fits against the inner wall of the wire-holding groove 9, which plays a guiding and limiting role for the connecting line 101, reducing unnecessary bending and stress concentration of the cable at the interface, reducing the risk of cable damage, and helping to keep the lines tidy during on-site operations.

[0057] Example 2:

[0058] refer to Figures 1-8 Staff members used the structure disclosed in this utility model in a smart city road green belt vegetation monitoring project.

[0059] Technicians used this novel plant canopy analyzer to monitor the canopy structure of greenery surrounding traffic lights. The analyzer was used to assess the canopy light transmittance of London plane trees to optimize pruning techniques within the traffic light's field of vision. The main collecting unit 1 is made of 6061 aluminum alloy, 650 mm in length and 45 mm in diameter, with a 150-degree fisheye lens sensor integrated at the front end. The connecting cable 101 is a shielded twisted-pair cable, connected to the main unit module 102 via an aviation plug. The main unit module 102 is equipped with a 5-inch touchscreen that displays leaf area index data in real time.

[0060] The operator holds the main collection body 1 with one hand, with their palm resting on the 3mm thick silicone anti-slip ring 204. The PA66 nylon curved rods 2 on both sides are extended outwards to a working angle of 60 degrees. At this point, the 2Cr13 stainless steel inlaid arc plate 303 on the shaft 203 engages with the third-position inlaid arc groove 302 of the semi-circular part 301 for positioning. The operator rests their right forearm on the proximal pad 201 and the distal pad 202. The proximal pad 201 is a 15mm deep groove molded from TPE material, while the distal pad 202 is a 12mm high arc-shaped protrusion, effectively distributing the weight of the instrument. During two hours of continuous measurement, the operator's arm fatigue decreased by 70%, and the instrument vibration amplitude was controlled within ±0.5 degrees.

[0061] When temporary data recording is needed, the operator presses control button 505 to unlock support module 5, unfolding the POM support plate 502 by 120 degrees. At this time, the collecting body 1 stands on the ground at a 45-degree angle, with the EPDM rubber end pad 8 at the end being 6 mm thick and its cable slot 9 being 4 mm deep, effectively protecting the connector 101 from ground pressure. When the bent rod 2 is stored, the distal pad 202 elastically deforms and snaps into the SUS304 stainless steel L-shaped hook 4 to prevent shaking during transportation.

[0062] This device increases daily measurement efficiency by 3 times, accurately acquiring canopy opening data at 15 key points around traffic lights, providing precise data for municipal greening pruning.

[0063] The working principle of this utility model:

[0064] Step 1: The operator holds the analyzer's collection body 1 with one hand, naturally gripping the anti-slip rubber ring 204 to increase friction and prevent slippage. The other hand extends outward to the curved rods 2 symmetrically positioned on both sides of the collection body 1. The curved rods 2 rotate via the shaft 203.

[0065] During rotation, the retaining piece 303 fixed on the shaft 203 disengages from an retaining groove 302. When rotating to the next comfortable or desired angle, the retaining piece 303 engages with the corresponding retaining groove 302 under pressure. The positioning module 3, through this cooperation between the retaining piece 303 and the retaining groove 302, reliably fixes the bent rod 2 at multiple preset angles to accommodate different operators' usage habits or different measurement postures, such as horizontal or inclined measurements.

[0066] Step 2: When formally collecting canopy data, the operator rests the forearm of the arm holding the forearm on the proximal pad 201 and distal pad 202 on the two curved rods 2 respectively. The concave design of the proximal pad 201 fits the forearm near the elbow, while the convex design of the distal pad 202 adapts to the curve of the distal end of the forearm.

[0067] With these two support points, part of the instrument's weight and load is effectively distributed to the entire forearm, thereby significantly reducing the gripping force that the wrist and hand muscles need to continuously output. This fundamentally avoids muscle fatigue and tremors caused by prolonged operation, ensuring the stability of the instrument and the accuracy of the measurement results during data acquisition.

[0068] Step 3: When the instrument needs to be temporarily placed, the operator adjusts the bent rod 2 to a suitable support angle, then presses the control button 505 inward with their finger, which drives the L-shaped fixing part 504 to compress the reset spring 506 and exit from the fixing groove 503, thereby unlocking the support plate 502. The support plate 502 of the support module 5 is then rotated out from the end of the bent rod 2, and the instrument with the support feet extended is placed on the ground. At this time, the instrument is supported by the support plate 502 and the bent rod 2 together to form a stable triangular support surface, so that the collecting body 1 is in an inclined state.

[0069] This tilted placement ensures that the connector 101 at the end does not directly contact the ground and bears the full weight of the instrument. Meanwhile, the end pad 8 and its cable retainer 9 provide additional cushioning and stress relief, effectively preventing the connector from loosening under pressure and cable damage. The sensitive probe at the front end of the collection body 1 avoids direct contact with the ground, preventing contamination and impacts.

[0070] Step 4: When the instrument needs to be moved or stored, the operator rotates the support plate 502 to a position close to the bent rod 2. The support plate 502 smoothly presses against the auxiliary inclined surface 7 and pushes the L-shaped fixing piece 504 backward. After the support plate 502 is in place, the L-shaped fixing piece 504 automatically engages with its fixing groove 503 under the action of the return spring 506, thus simplifying the storage operation. Then, the bent rod 2 is rotated inward so that it is close to the collection body 1. At this time, the distal pad 202 can be slightly deformed and fit against the inner surface of the L-shaped hook 4 to form an auxiliary fixation, preventing the bent rod 2 from accidentally opening during carrying and transportation. The L-shaped hook 4 itself can also be used to temporarily suspend the entire instrument on a bracket or hook.

[0071] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
