Description

Technical Field

[0001] This invention relates to the field of chlorophyll fluorescence imaging technology, specifically to an active plate that facilitates sample measurement using a chlorophyll fluorescence imaging system. Background Technology

[0002] Chlorophyll fluorescence imaging technology, as a core non-destructive testing technique in fields such as plant photosynthetic physiology research, abiotic stress response analysis, and genetic breeding screening, captures the fluorescence signal generated after chlorophyll in plant leaves is excited. This allows for precise reflection of the functional state, damage level, and adaptive changes of the photosynthetic system, providing crucial data support for agricultural research and ecological monitoring. The sample plate, as the component directly supporting the plant leaves and stems, directly determines the relative positional accuracy of the sample imaging area and the light source, the stability of sample fixation, and the convenience of experimental operation through its structural design.

[0003] The sample plates used with existing chlorophyll fluorescence imaging systems are mostly assembled with the imager using fixed connections such as bolts and clips, which cannot be flexibly adjusted according to actual detection needs, thus affecting their practicality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a movable plate that facilitates sample measurement in chlorophyll fluorescence imaging systems. This solves the problem that traditional chlorophyll fluorescence imaging systems typically use fixed sample plates that cannot be adjusted in height according to detection requirements, thus affecting practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a movable plate for sample measurement using a chlorophyll fluorescence imaging system, comprising a chlorophyll fluorescence imager body, an adjustment structure fixedly connected to one side of the chlorophyll fluorescence imager body, a movable plate disposed on one side of the adjustment structure, adsorption holes uniformly formed on the top of the movable plate, a gas collection chamber formed inside the movable plate, connecting plates symmetrically fixedly connected inside the movable plate, an mounting plate fixedly connected to the opposite side of the connecting plate, a vacuum pump fixedly mounted on the top of the mounting plate, an intake pipe fixedly connected to the input end of the vacuum pump, an exhaust pipe fixedly connected to the output end of the vacuum pump, an electric push rod fixedly mounted on the bottom of the mounting plate, a moving block fixedly connected to the output end of the electric push rod, through holes uniformly formed on one side of the moving block, the outer wall of the moving block slidably connected to the inner wall of the movable plate, and an exhaust pipe fixedly connected to the middle of the movable plate.

[0006] By adopting the above technical solution, the moving block is moved by an electric push rod. Through the cooperation of the electric push rod with the exhaust pipe and the gas supply pipe, the height adjustment of the movable plate and the fixation of the blade are realized. This solves the problem that the sample plates of traditional chlorophyll fluorescence imaging systems are mostly fixed and cannot be adjusted in height according to detection needs, which affects practicality.

[0007] Preferably, the adsorption hole is connected to the gas collection chamber, one end of the air intake pipe is located in the gas collection chamber of the movable plate, and the outer wall of the exhaust pipe is fixedly connected to one side of the chlorophyll fluorescence imager body.

[0008] Preferably, the adjustment structure includes a wedge-shaped movable block, two fixed columns, and two wedge-shaped sliders. The top of the wedge-shaped movable block is fixedly connected to the bottom of the movable block, and the bottom of the wedge-shaped sliders is slidably connected to the inside of the movable plate. The wedge-shaped surface of the wedge-shaped movable block matches the wedge-shaped surface of the wedge-shaped sliders.

[0009] Preferably, a sliding column is fixedly connected to the opposite side of the wedge-shaped slider, the outer wall of the sliding column is slidably connected to the inside of the movable plate, and an L-shaped locking block is fixedly connected to one end of the sliding column.

[0010] Preferably, the sliding column is located below the gas supply pipe, and the gas supply pipe is located below the exhaust pipe.

[0011] Preferably, the outer wall of the L-shaped block is slidably connected to the inside of the movable plate, and a spring is fixedly connected to the side of the L-shaped block that is away from it, with one end of the spring fixedly connected to one side of the movable plate.

[0012] Preferably, the bottom end of the fixed column is fixedly connected to one side of the chlorophyll fluorescence imager body, the top of the fixed column is fixedly connected to a piston block, the outer wall of the piston block is fitted with a movable cylinder, and one side of the movable cylinder is slidably connected to the outer wall of the fixed column.

[0013] Preferably, an air inlet is provided in the middle of the movable cylinder, a limiting block is fixedly connected to the top of the movable cylinder, and a slot is provided on the side of the limiting block that is away from it.

[0014] Preferably, the air inlet of the movable cylinder is connected to one end of the sliding column, and the slot of the limiting block can engage with one end of the L-shaped block.

[0015] Preferably, an installation door is installed on one side of the chlorophyll fluorescence imager body, and a work table is installed at the bottom of the chlorophyll fluorescence imager body, with support legs evenly and fixedly connected to the bottom of the work table.

[0016] Working Principle: The chlorophyll fluorescence imager detects the leaves on the movable plate. A vacuum pump draws air from the gas collection chamber through the suction pipe, uniformly adsorbing the leaves on the movable plate and confining them to the plate. An electric push rod drives a moving block to slide within the movable plate. When the moving block slides to one end of the second exhaust pipe, the air discharged from the first exhaust pipe enters the movable cylinder, thus adjusting the height of the movable plate. When the moving block blocks the gas supply pipe, the movable plate is confined to the adjusted height. To lower the height of the movable plate, the electric push rod drives the moving block to slide between the gas supply pipe and the second exhaust pipe. The weight of the movable plate then forces the gas in the movable cylinder to be discharged sequentially through the gas supply pipe and the second exhaust pipe, thus lowering the height of the movable plate. This allows for adjustment of the height of the movable plate within the chlorophyll fluorescence imager, enabling the adjustment of the leaf height on the movable plate according to detection requirements, ensuring an appropriate distance between the sample imaging area and the light source.

[0017] When the movable plate needs to be removed, the moving block causes the wedge-shaped movable block to come into contact with the wedge-shaped slider, which in turn causes the two L-shaped locking blocks to move away from each other. This allows the lateral end of the L-shaped locking block to leave the slot in the limiting block, thus enabling the movable plate to be removed from the movable cylinder. When the wedge-shaped movable block is not in contact with the wedge-shaped slider, the spring ensures that the L-shaped locking block remains locked in the slot of the limiting block, allowing for quick installation and removal of the movable plate and facilitating maintenance.

[0018] This invention provides an active plate that facilitates sample measurement using a chlorophyll fluorescence imaging system. It offers the following advantages: 1. This invention uses an electric push rod to move the moving block. Through the cooperation of the electric push rod with the exhaust pipe and the gas supply pipe, the height of the movable plate and the blade are adjusted and fixed. This solves the problem that the sample plates of traditional chlorophyll fluorescence imaging systems are mostly fixed and cannot be adjusted in height according to detection needs, which affects practicality.

[0019] 2. In this invention, when the moving block drives the wedge-shaped movable block to abut against the wedge-shaped slider, the two wedge-shaped sliders move away from each other within the movable plate. This causes the two sliding columns to drive the two L-shaped locking blocks away from each other, so that the lateral end of the L-shaped locking block leaves the slot in the limiting block. This allows the movable plate to be removed from the movable cylinder. When the wedge-shaped movable block is not in contact with the wedge-shaped slider, the spring ensures that the L-shaped locking block remains locked in the slot of the limiting block. This allows for quick installation and removal of the movable plate, facilitating maintenance.

[0020] 3. In this invention, an electric push rod drives a moving block to slide within a movable plate. When the moving block blocks one end of the exhaust pipe, the height of the movable plate is adjusted. When the moving block blocks the gas supply pipe, the movable plate is limited to the adjusted height. When it is necessary to lower the height of the movable plate, the electric push rod drives the moving block to slide between the gas supply pipe and the exhaust pipe. The gas in the movable cylinder is then discharged sequentially through the gas supply pipe and the exhaust pipe using the weight of the movable plate, thereby lowering the height of the movable plate. This achieves both height adjustment of the movable plate and fixation of the blades using the adsorption holes and the gas collection chamber. Attached Figure Description

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a movable plate for sample measurement using a chlorophyll fluorescence imaging system. The plate includes a chlorophyll fluorescence imager body 1, an adjustment structure fixedly connected to one side of the body 1, and a movable plate 6 on one side of the adjustment structure. Adsorption holes 9 are evenly distributed on the top of the movable plate 6, and a gas collection chamber 10 is formed inside the movable plate 6. A connecting plate 12 is symmetrically fixedly connected inside the movable plate 6, and a mounting plate 13 is fixedly connected to the opposite side of the connecting plate 12. A vacuum pump 14 is fixedly mounted on the top of the mounting plate 13. A suction pipe 19 is fixedly connected to the input end of the vacuum pump 14, and an exhaust pipe 20 is fixedly connected to the output end of the vacuum pump 14. An electric push rod 21 is fixedly mounted on the bottom of the mounting plate 13, and a moving block 15 is fixedly connected to the output end of the electric push rod 21. Through holes 22 are evenly distributed on one side of the moving block 15, and the outer wall of the moving block 15 is slidably connected to the inner wall of the movable plate 6. An exhaust pipe 5 is fixedly connected to the middle of the movable plate 6.

[0025] Specifically, the chlorophyll fluorescence imager body 1 is used to detect the leaves on the movable plate 6. By adjusting the structure, the height of the movable plate 6 within the chlorophyll fluorescence imager body 1 can be adjusted as needed. The height of the leaves on the movable plate 6 is then adjusted according to the detection requirements, ensuring the sample imaging area is at an appropriate distance from the light source. The vacuum pump 14 and the electric push rod 21 are installed inside the movable plate 6 via the connecting plate 12 and the mounting plate 13. The operation of the vacuum pump 14 draws air from the gas collection chamber 10 through the suction pipe 19 and discharges it into the interior of the movable plate 6 through the exhaust pipe 20. The uniformly spaced adsorption holes 9 on the top of the movable plate 6 then uniformly adsorb the leaves, confining the detected leaves on the movable plate 6 for convenient leaf detection.

[0026] When the electric push rod 21 is running, it drives the moving block 15 to slide within the movable plate 6. When the moving block 15 slides to one end of the exhaust pipe 2 5, its outer wall blocks one end of the exhaust pipe 2 5. Thus, by utilizing the opening of the through hole 22, the air discharged by the exhaust pipe 20 can enter the adjustment structure through the air supply pipe 11, thereby adjusting the height of the movable plate 6. When the moving block 15 slides to one end of the air supply pipe 11, the air supply pipe 11 is blocked, so that the air discharged by the exhaust pipe 20 is discharged through the exhaust pipe 2 5 to the outside of the chlorophyll fluorescence imager body 1, and the movable plate 6 is limited to the adjusted height. When it is necessary to lower the height of the movable plate 6, the electric push rod 21 drives the moving block 15 to slide between the air supply pipe 11 and the exhaust pipe 2 5. Thus, by utilizing the weight of the movable plate 6, the gas of the adjustment structure is discharged sequentially through the air supply pipe 11 and the exhaust pipe 2 5, thereby lowering the height of the movable plate 6.

[0027] When the movable plate 6 needs to be disassembled, the moving block 15 is slid downwards, thereby allowing the movable plate 6 to be released from the installation of the adjustment structure. The movable plate 6 can then be removed for maintenance. The moving block 15 is then moved by the electric push rod 21. Through the cooperation of the electric push rod 21 with the exhaust pipe 5 and the gas supply pipe 11, the height adjustment of the movable plate 6 and the fixation of the blades are realized. This solves the problem that the sample plates of traditional chlorophyll fluorescence imaging systems are mostly fixed and cannot be adjusted in height according to the detection requirements, which affects the practicality.

[0028] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 4 The adsorption hole 9 is connected to the gas collection chamber 10. One end of the air intake pipe 19 is located inside the gas collection chamber 10 of the movable plate 6. The outer wall of the exhaust pipe 2 5 is fixedly connected to one side of the chlorophyll fluorescence imager body 1. An installation door 4 is installed on one side of the chlorophyll fluorescence imager body 1. A worktable 2 is installed at the bottom of the chlorophyll fluorescence imager body 1. Support legs 3 are evenly fixedly connected to the bottom of the worktable 2.

[0029] Specifically, the air intake 19 is connected to the air collection chamber 10 through the adsorption hole 9, and the air intake pipe 19 is connected to the air collection chamber 10, which facilitates the flow of other air and limits the movement of the leaves. The exhaust pipe 2 5 is fixed to the chlorophyll fluorescence imager body 1, thereby installing the exhaust pipe 2 5. The exhaust pipe 2 5 can be a flexible hose. The installation of the installation door 4 facilitates the detection operation. The chlorophyll fluorescence imager body 1 is installed through the setting of the work table 2 and the support leg 3.

[0030] Please see the appendix Figure 2 - Appendix Figure 6The adjustment structure includes a wedge-shaped movable block 23, two fixed posts 7, and two wedge-shaped sliders 24. The top of the wedge-shaped movable block 23 is fixedly connected to the bottom of the movable block 15, and the bottom of the wedge-shaped sliders 24 is slidably connected to the inside of the movable plate 6. The wedge-shaped surfaces of the wedge-shaped movable block 23 and the wedge-shaped surfaces of the wedge-shaped sliders 24 are matched. A sliding post 17 is fixedly connected to the opposite side of the wedge-shaped sliders 24. The outer wall of the sliding post 17 is slidably connected to the inside of the movable plate 6, and an L-shaped locking block 26 is fixedly connected to one end of the sliding post 17. The sliding post 17 is located below the air supply pipe 11, which is located below the exhaust pipe 5. The outer wall of the L-shaped locking block 26 is slidably connected to the inside of the movable plate 6, and a spring 25 is fixedly connected to the opposite side of the L-shaped locking block 26. One end of the spring 25 is fixedly connected to one side of the movable plate 6. The bottom end of the fixed column 7 is fixedly connected to one side of the chlorophyll fluorescence imager body 1. A piston block 27 is fixedly connected to the top of the fixed column 7. A movable cylinder 8 is installed on the outer wall of the piston block 27, and one side of the movable cylinder 8 is slidably connected to the outer wall of the fixed column 7. An air inlet 28 is provided in the middle of the movable cylinder 8. A limiting block 16 is fixedly connected to the top of the movable cylinder 8, and a slot 18 is provided on the side of the limiting block 16 away from it. The air inlet 28 of the movable cylinder 8 is connected to one end of the sliding column 17, and the slot 18 of the limiting block 16 can engage with one end of the L-shaped locking block 26.

[0031] Specifically, by matching the wedge-shaped movable block 23 with the wedge-shaped slider 24, when the moving block 15 causes the wedge-shaped movable block 23 to abut against the wedge-shaped slider 24, the two wedge-shaped sliders 24 move away from each other within the movable plate 6, causing the two sliding columns 17 to slide within the movable plate 6. This, in turn, causes the two L-shaped locking blocks 26 to move away from each other, so that one end of the L-shaped locking block 26 leaves the slot 18 in the limiting block 16, thereby allowing the movable plate 6 to be removed from the movable cylinder 8. When the wedge-shaped movable block 23 is not in contact with the wedge-shaped slider 24, the spring 25 ensures that the L-shaped locking block 26 remains locked within the slot 18 of the limiting block 16, allowing for quick installation and removal of the movable plate 6 for easy maintenance.

[0032] By opening the air inlet 28, air from the gas supply pipe 11 can easily enter the interior of the movable cylinder 8. With the fixed column 7 fixed to the chlorophyll fluorescence imager body 1 and the piston block 27, the pressure of the gas allows the two movable cylinders 8 to slide upward on the two fixed columns 7 respectively, thereby driving the movable plate 6 to adjust its height so that the sample imaging area is at an appropriate distance from the light source.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
