Description

Technical Field

[0001] This utility model belongs to the field of biodiversity conservation, and relates to plant conservation technology, particularly to a sterile photographing stand for plant materials suitable for plant conservation. Background Technology

[0002] In the field of biodiversity conservation, plant conservation is crucial. Taking orchids as an example, aseptic photography of orchid materials is an important process in orchid conservation, and it is of great significance for the observation, conservation, and scientific research of aseptic materials.

[0003] Orchid seeds are only 50 to 300 micrometers in diameter, with each pod containing millions of powdery seeds. Their germination process requires continuous observation of the protocorm's morphological changes. Traditional tissue culture observation involves opening the glass door of a clean bench and photographing the culture dishes inside. This not only exposes the dishes to contamination risks (statistics show a 12% contamination probability within 10 seconds of opening the lid), but also creates blind spots in the photographing process due to the upright position and fixed angle of the dishes. Under these conditions, comprehensive observation of tissue culture cannot be guaranteed, and approximately 35% of protocorm developmental abnormalities cannot be detected in time, resulting in the loss of orchid tissue culture material.

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0054] The purpose of this invention is to provide a sterile photographing stand for plant materials suitable for plant conservation. This stand is specifically designed for tilting and supporting culture dishes in a clean bench, and the tilt angle is adjustable, thereby enabling the culture dishes to be fully exposed to the photographing lens, reducing or even eliminating blind spots in the photographing, and improving the comprehensiveness of tissue culture observation, thus solving the problems existing in the prior art.

[0055] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] Example 1

[0057] This embodiment provides a sterile photographing stand 100 for plant materials suitable for plant conservation, for placement within a clean bench. It includes a base 1, a supporting backplate 2, a backplate support 3, and a support container. The base 1 stably supports the entire stand. The supporting backplate 2 is located above the base 1, and its bottom end is movably connected to the base 1, allowing for an adjustable angle between the backplate 2 and the base 1, thus adjusting the tilt angle of the culture dish on the stand. The top end of the backplate support 3 is movably connected to the backplate 2, and its bottom end is movably connected to the base 1. After the angle between the backplate 2 and the base 1 is adjusted, the backplate support 3 can tilt the backplate 2 above the base 1 to maintain its tilt angle. The support container is located on the front side of the supporting backplate 2, arranged at an angle to it. The support container holds the culture dish, allowing it to rest between the front side of the supporting backplate 2 and the support container. The aforementioned support is specifically designed for tilting and supporting culture dishes inside a clean bench. By adjusting the tilt angle of the support back plate 2, and after the angle is adjusted to the correct position, the support back plate 2 is supported and fixed by the back plate support component 3. This allows the tilt angle of the culture dish to be adjusted, enabling the culture dish to meet different shooting angles and be fully exposed to the shooting lens, reducing or even eliminating blind spots and improving the comprehensiveness of tissue culture observation.

[0058] In some feasible implementations, multiple carriers are provided to adapt to different shaped petri dishes; any one carrier is used to be detachably connected to the front side of the support back plate 2, and multiple carriers are detachably connected to the front side of the support back plate 2 by mutual substitution, that is, only one (set) of carriers is installed on the front side of the support back plate 2 at a time. After the shape or size of the petri dish is changed, the carrier on the front side of the support back plate 2 is removed and replaced with another set of suitable carriers.

[0059] Specifically, each carrying component includes at least two identical carrying plates, and the lengths of the carrying plates in different carrying components are different; the front side of the support back plate 2 is provided with multiple horizontally arranged insertion holes 21, and the number of insertion holes 21 is not less than the number of carrying plates in each carrying component; each carrying plate has an insertion block at its end, and each carrying plate can be inserted and adapted to any insertion hole 21 through the insertion block. The insertion block can be a protrusion specially provided at the end of the carrying plate, or the end of the carrying plate can be used directly as the insertion block.

[0060] In some feasible implementations, each load includes two identical load plates; all the sockets 21 are divided into two groups, and the two groups of sockets 21 are symmetrically spaced, and each group of sockets 21 includes at least two sockets 21; the arrangement of the two groups of sockets 21 extends toward both sides of the support back plate 2.

[0061] Specifically, taking a setup with two culture plates as an example, the two culture plates in one culture plate are longer than the two culture plates in the other culture plate. To distinguish them, the shorter culture plate is called the short culture plate 4, and the longer culture plate is called the long culture plate 5. Both the long culture plate 5 and the short culture plate 4 are long strip-shaped culture plates, with an overall rectangular shape, and the width and thickness of the long culture plate 5 and the short culture plate 4 are the same. Both the long culture plate 5 and the short culture plate 4 are directly inserted into the insertion hole 21 using their own ends. After insertion, both the long culture plate 5 and the short culture plate 4 are in clearance fit with the insertion hole 21, and the insertion hole 21 is deep enough but does not penetrate through the support back plate 2, so as to ensure that after the long culture plate 5 and the short culture plate 4 are inserted into the insertion hole 21, they can be stably connected to the support back plate 2 and provide stable support for the culture dish.

[0062] like Figure 1 As shown, each set of insertion holes 21 contains two insertion holes 21. The two plates in each carrier are inserted into different insertion holes 21 respectively, and the distance between the two plates can be adjusted to accommodate petri dishes of different sizes.

[0063] like Figures 2-4 The diagram shows a structure in which a short substrate plate 4 is inserted into the supporting back plate 2. This structure is suitable for thinner culture dishes such as round culture dishes 7 and square culture dishes 8. Figure 3 The diagram shows a short plate 4 supporting a circular culture dish 7. Figure 4 The diagram shows a short plate 4 supporting a square culture dish 8.

[0064] like Figure 5 and Figure 6 The diagram shows a structure in which a long substrate plate 5 is inserted into the supporting back plate 2. This structure is suitable for bottle-shaped culture dishes (i.e., culture flasks 9) with a relatively long axial length. Figure 6 The diagram shown is a schematic of the structure of the long plate 5 supporting the culture bottle 9.

[0065] In some feasible implementations, the bottom end of the support back plate 2 is preferably hinged to the front end of the base 1 via a pivot 6. Specifically, the pivot 6 is fixed at one of the bottom end of the support back plate 2 and the front end of the base 1, and a shaft housing adapted to the rotation of the pivot 6 is provided at the other of the bottom end of the support back plate 2 and the front end of the base 1. For example, the pivot 6 is fixed to the front end of the base 1, and the bottom end of the support back plate 2 is provided with a shaft housing adapted to the rotation of the pivot 6. The support back plate 2 is rotated and fitted onto the pivot 6 via the shaft housing, thereby achieving the hinge connection between the support back plate 2 and the base 1. This design allows the support back plate 2 and the base 1 to fold and overlap, reducing the overall volume of the bracket when not in use, making it convenient for storage or carrying.

[0066] In some other embodiments, the bottom end of the support back plate 2 and the front end of the base 1 can also be hinged. Hinging is a mature existing technology, and commonly available hinge components can be used between the bottom end of the support back plate 2 and the front end of the base 1.

[0067] Considering that reflections at the bottom of the culture vessel and environmental noise interference can lead to low imaging resolution during imaging, some feasible implementations use a non-transparent background plate, such as a white or black background plate, to prevent light transmission or reflection, thus providing a background color for the culture dish and avoiding low imaging resolution caused by reflections at the bottom of the culture vessel and environmental noise interference. Alternatively, a background layer (including but not limited to a white or black layer) can be applied to the front side of the support back plate 2 to provide a background color for the culture dish, or a non-transparent background film (including but not limited to a white or black background film) can be applied to the front side of the support back plate 2 to provide a background color for the culture dish.

[0068] The support backplate 2 is preferably a flat plate structure with uniform thickness. In addition, in order to further improve the imaging resolution, baffles can be provided on both sides of the front side of the support backplate 2, or the support backplate 2 can be directly set as an arc-shaped back surface, and the aforementioned front side of the support backplate 2 is the concave surface of the arc-shaped back surface.

[0069] In some feasible implementations, the support backplate 2 has multiple upper slots 22 along its height direction, and the base 1 has multiple lower slots 11 along its front-to-back direction. The backplate support 3 is a support plate, and the top end of the support plate can be inserted into any one of the upper slots 22, and the bottom end of the support plate can be inserted into any one of the lower slots 11. By inserting both ends of the support plate (i.e., the backplate support 3) into the upper slots 22 and lower slots 11 respectively, the support backplate 2 can be formed at a fixed angle for supporting the petri dish during photography. By inserting the support plate (i.e., the backplate support 3) into different upper slots 22 and lower slots 11, the support backplate 2 can be supported to different tilt angles, thereby achieving the purpose of adjusting the angle of the support backplate 2.

[0070] It should be noted that the upper slot 22 is located on the back of the support back plate 2 and is arranged near the top of the support back plate 2. Neither of the upper slots 22 penetrates the thickness direction of the support back plate 2, and both upper slots 22 are perpendicular to the support back plate 2. Similarly, the lower slot 11 is located on the upper surface of the base 1 and is arranged near the rear end of the base 1. Neither of the lower slots 11 penetrates the thickness direction of the base 1, and both lower slots 11 are perpendicular to the base 1. Both the upper slots 22 and the support plate are clearance-fitted. When the support plate (i.e., the back plate support 3) supports the aforementioned support back plate 2, the upper slots 22 and the slot sides of the upper slots 22 are mainly used to limit the support plate. Considering that the support plate is generally in an inclined state, to ensure that the support plate can be smoothly inserted into either upper slot 22 or the upper slot 22, it is preferable that the width of both upper slots 22 is wider than the thickness of the support plate.

[0071] As a preferred example: the base 1, the support back plate 2, the back plate support 3, the short carrying plate 4 and the long carrying plate 5 are all preferably made of PP material. The support back plate 2 is black as a whole and is rectangular. For example, the length × width of the support back plate 2 is 25cm × 25cm and the thickness of the support back plate 2 is 0.5cm.

[0072] Furthermore, the insertion hole 21 is preferably a rectangular insertion hole with a length × width × depth of 1cm × 0.5cm × 0.3cm, which can accommodate carriers of different lengths. Both the short carrier 4 and the long carrier 5 are preferably white transparent PP boards, wherein the short carrier 4 has a length × width of 2cm × 1cm and a thickness of 0.5cm, and the long carrier 5 has a length × width of 7cm × 1cm and a thickness of 0.5cm.

[0073] Furthermore, the length × width × depth of the upper slot 22 and the lower slot 11 are both 5cm × 0.7cm × 0.2cm; the length × width × thickness of the support plate (i.e. the back plate support 3) are 30cm × 5cm × 0.5cm.

[0074] The following describes in detail the usage of the aseptic photographing support 100 for plant materials applicable to plant conservation described above, using specific examples.

[0075] Example 1: Taking a circular petri dish 7 used for cultivating sterile orchid materials as an example, the method of use is as follows: Open the autoclaved imaging stand (i.e., the sterile imaging stand 100 for plant materials suitable for plant conservation) in a laminar flow hood; according to the size of the circular petri dish 7, insert the two short plates 4 into a pair of symmetrical holes 21 in the support back plate 2; adjust the angle between the support back plate 2 and the base 1 according to the required imaging angle, and insert the two ends of the support plate (i.e., the back plate support 3) into the corresponding upper slot 22 and lower slot 11 respectively to fix the angle of the support back plate 2. Then place the circular petri dish 7 used for cultivating sterile orchid materials as follows: Figure 3 As shown, the circular petri dish 7 is placed on two short plates 4, with its bottom resting against the support back plate 2.

[0076] If photography is not required, close the laminar flow hood to ensure the circular culture dish 7 is in a sterile environment; when photography is required, simply open the laminar flow hood. During photography, the support plate (i.e., the back plate support 3) can be moved and disassembled to adjust the tilt angle of the support back plate 2 and the circular culture dish 7 in front of it to ensure that there are no blind spots in the photography; after the tilt angle of the support back plate 2 and the circular culture dish 7 in front of it is adjusted to the correct position, insert both ends of the support plate (i.e., the back plate support 3) into the corresponding upper slot 22 and lower slot 11 respectively.

[0077] To ensure a sterile environment within the laminar flow hood, the support frame and petri dishes must be sterilized and disinfected each time the laminar flow hood is opened. During prolonged use, the support frame and petri dishes can also be sterilized with ultraviolet light and wiped with alcohol to ensure a sterile environment.

[0078] Example 2: Taking a square petri dish 8 used for cultivating sterile orchid materials as an example, the method of use is as follows: Open the autoclaved imaging stand (i.e., the sterile imaging stand 100 for plant materials suitable for plant conservation) in a laminar flow hood; according to the size of the square petri dish 8, insert the two short plates 4 into a pair of symmetrical holes 21 in the support back plate 2; adjust the angle between the support back plate 2 and the base 1 according to the required imaging angle, and insert the two ends of the support plate (i.e., the back plate support 3) into the corresponding upper slot 22 and lower slot 11 respectively to fix the angle of the support back plate 2. Then place the square petri dish 8 used for cultivating sterile orchid materials as follows: Figure 4 As shown, the square petri dish 8 is placed on two short plates 4, with its bottom resting against the support back plate 2.

[0079] If no photography is required, close the laminar flow hood to ensure the square petri dish 8 is in a sterile environment; when photography is required, open the laminar flow hood. During photography, the support plate (i.e., the back plate support 3) can be moved and disassembled to adjust the tilt angle of the support back plate 2 and the square petri dish 8 in front of it to ensure no blind spots in the photography; after the tilt angle of the support back plate 2 and the square petri dish 8 in front of it is adjusted, insert both ends of the support plate (i.e., the back plate support 3) into the corresponding upper slot 22 and lower slot 11 respectively.

[0080] To ensure a sterile environment within the laminar flow hood, the support frame and petri dishes must be sterilized and disinfected each time the laminar flow hood is opened. During prolonged use, the support frame and petri dishes can also be sterilized with ultraviolet light and wiped with alcohol to ensure a sterile environment.

[0081] Example 3: Taking the culture bottle 9 for cultivating sterile orchid materials as an example, the method of use is as follows: Open the autoclaved imaging stand (i.e., the sterile imaging stand 100 for plant materials suitable for plant conservation) in the laminar flow hood; according to the size of the culture bottle 9, insert the two long carrier plates 5 into a pair of symmetrical insertion holes 21 in the support back plate 2; adjust the included angle between the support back plate 2 and the base 1 according to the required shooting angle, and insert the two ends of the support plate (i.e., the back plate support 3) into the corresponding upper slot 22 and lower slot 11 respectively to fix the angle of the support back plate 2. Then place the culture bottle 9 for cultivating sterile orchid materials as follows: Figure 6 As shown, the culture flasks are placed on two long plates 5, with the bottom of the culture flasks resting against the support back plate 2.

[0082] If no photography is required, close the laminar flow hood to ensure that the culture flask 9 is in a sterile environment; when photography is required, simply open the laminar flow hood. During photography, the support plate (i.e., the back plate support 3) can be moved and disassembled to adjust the tilt angle of the support back plate 2 and the culture flask 9 in front of it to ensure that there are no blind spots in the photography; after the tilt angle of the support back plate 2 and the culture flask 9 in front of it is adjusted, insert both ends of the support plate (i.e., the back plate support 3) into the corresponding upper slot 22 and lower slot 11 respectively.

[0083] To ensure a sterile environment within the laminar flow hood, the support frame and petri dishes must be sterilized and disinfected each time the laminar flow hood is opened. During prolonged use, the support frame and petri dishes can also be sterilized with ultraviolet light and wiped with alcohol to ensure a sterile environment.

[0084] In summary, the beneficial effects of the aseptic photographing support 100 for plant materials proposed in this solution, suitable for plant conservation, are as follows:

[0085] (1) The overall structure of the support is simple, small in size, and foldable, making it easy to store and carry when not in use. The support can be sterilized by high-pressure steam after being folded, and can also be sterilized by ultraviolet light and wiped with alcohol during long-term shooting to ensure a sterile environment during the shooting process.

[0086] (2) This support tool can stably support the petri dish or culture bottle and supports adjusting the shooting angle of the petri dish / bottle, thus avoiding the problem of blind spots in the shooting.

[0087] (3) The support back plate of this support tool has a background surface, which can effectively eliminate the interference of cluttered background and reflection of petri dishes / bottles, making the image clearer.

[0088] (4) This support tool is particularly suitable for photographing sterile materials of orchid plants in a clean bench, solving problems such as easy contamination during the photographing process of sterile materials, cluttered shooting background, unsuitable shooting angle, and blind spots.

[0089] (5) The support plate is detachable and movable, making the adjustment of the support angle of the support back plate more convenient and efficient.

[0090] (6) All the plates are made of white transparent PP material, which is conducive to the observation and photography of sterile materials.

[0091] Example 2

[0092] This embodiment provides a sterile photographing stand 100 for plant materials suitable for plant conservation. The difference between this stand and Embodiment 1 is that one of the supporting backplate 2 and the base 1 is hinged to the backplate support member 3, while the other has multiple slots for insertion into the backplate support member 3. For example, the bottom end of the backplate support member 3 is hinged to the base 1, while the top end of the supporting backplate 2 has multiple upper slots 22. Inserting the top end of the backplate support member 3 into different upper slots 22 allows it to be adjusted and fixed to the corresponding angle.

[0093] Example 3

[0094] This embodiment provides a sterile photographing support 100 for plant materials suitable for plant conservation. The difference between this support and embodiments 1 and 2 is that: multiple objects are simultaneously arranged on the front side of the support back plate 2, and these objects are spaced apart from the top to the bottom of the support back plate 2; each object includes multiple identical flip-over plates, and the multiple flip-over plates of the same object are arranged horizontally, with different lengths for the flip-over plates of different objects; the bottom of each flip-over plate is hinged to the front side of the support back plate 2, and a limiting structure is provided below each flip-over plate to restrict its downward flipping; the limiting structure is located on the flip-over plate or on the front side of the support back plate 2, and can limit the downward flipping angle of the flip-over plate and support it, so that a space for placing a petri dish is formed between the flip-over plate and the support back plate 2.

[0095] In some feasible implementations, each carrier preferably includes two flip-over carrier plates, which can be flipped and fitted to overlap with the support back plate 2. At this time, the flip-over carrier plates are in a non-use state. Conversely, if it is necessary to use the flip-over carrier plates to support the culture dishes, the flip-over carrier plates of the corresponding length need to be flipped downwards until the flip-over carrier plates contact the limiting structure, and then the culture dishes can be placed on the flip-over carrier plates.

[0096] The arrangement of the carriers in this embodiment is suitable for situations where the area of ​​the support back plate 2 is large. Multiple carriers on the support back plate 2 are arranged at intervals to ensure that culture dishes can be placed on each carrier at the same time.

[0097] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention.
