Description

Technical Field

[0001] The invention relates to the field of space biological engineering, and in particular to a cyclotron and a method for simulating microgravity effects of plants. Background Art

[0002] Simulating microgravity environment is an important foundation for space science research. In recent years, the growth of various crops and model plants has been initially judged using the real microgravity environment of the International Space Station (ISS). However, in addition to the high cost, the limited experimental space of the space station cannot meet the needs of screening batch experimental materials, large-scale measurement of growth and development, and control of the planting environment. Therefore, how to reduce costs and simulate microgravity on the ground and conduct large-scale tests has become a technical problem that needs to be solved in space science.

[0003] There are basically two strategies for simulating microgravity at home and abroad. One is to use a strong magnetic field to offset gravity, and the other is to use rotation or random changes in position to make the direction of gravity felt by the sample constantly change. The former uses a strong magnetic field, which also brings high costs for long-term tracking of plant development. In comparison, the latter is cheaper and some research institutions have purchased it. However, the rotating devices and random positioning machines that simulate the microgravity effects of plants at home and abroad have not conducted large-scale measurements and experimental tracking of the development of the aboveground parts of plants, including plant height, number and angle of lateral branches, fruiting rate and other traits; the current devices are used for experimental materials such as animal cells, plant seedlings, and single mature plants, which cannot meet the needs of large-scale microgravity simulations in a unified environment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a rotator and method for simulating the microgravity effect of plants, which is used for batch testing the growth and development response of the aboveground parts of various plants under microgravity, and is particularly suitable for processing multiple samples at the same time.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A gyrator for simulating microgravity effect of plants, comprising: a main body box and a movable light source, the main body box comprising: a plurality of modules spliced ​​in series, the modules being provided with a plurality of clamps, the clamps being used to place plant culture containers and drive the plant culture containers to rotate;

[0006] The movable light source is arranged at the front side of the main box and has an adjustable distance relative to the main box, and is used to provide illumination for the plant samples.

[0007] The beneficial effect of the present invention is: it overcomes the technical difficulty that the current domestic plant microgravity simulation device cannot perform large-scale measurement and development tracking of plants. The rotator can realize batch testing of the growth and development response of various mature plants under microgravity, which is particularly suitable for processing multiple samples at the same time. The number of samples required by the user can be achieved at a low cost by connecting the required number of modules in series, and each module can be operated independently, so that the microgravity simulation effect of the same or different gradient speeds can be carried out for the same or different batches of samples at the same time, so as to achieve batch data collection under different experimental parameters; in addition, a dark environment can be realized to eliminate phototropic growth, and a single microgravity effect can be detected, or a top or side light source can be realized to induce phototropic growth and detect phototropic reactions under microgravity.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a plurality of groups of the modules are vertically arranged on the base, and a plurality of the clamps are evenly spaced apart along the vertical direction on each module.

[0010] The beneficial effects of adopting the above further scheme are: adding modules can increase the number of tests in the same period, which is particularly suitable for batch comparison of plant materials of multiple varieties, multiple genotypes, different developmental stages of the same genotype, etc. In addition, the relative position of the movable light source can be adjusted to detect the microgravity effect of plants under different directions of light and different light intensities.

[0011] Furthermore, the clamp includes: a connecting platform connected to the module, and a plurality of petals are extended from the connecting platform to clamp the plant culture container.

[0012] The beneficial effects of adopting the above further solution are: the clamps are connected to the modules independently, so the damage of a single clamp component does not affect the rotation of other clamps, and does not require overall maintenance and replacement; the multiple petals extending from the side of the connecting platform close to the movable light source provide a stable clamping environment for the plant culture container. The plant culture container is tightly clamped, effectively preventing the plant species from falling or being damaged due to unstable clamping during the rotation process, thereby ensuring the safety of the experiment and the accuracy of the data.

[0013] Furthermore, a power device is provided on a side of the module away from the clamp, and each clamp is connected to one power device, and the connecting platform and the petal body are driven to rotate by the power device.

[0014] The beneficial effect of adopting the above further scheme is that each clamp corresponds to a power device, which realizes independent control of a single plant culture container. This method makes it possible to adjust the rotation speed, direction and duration of each plant culture container individually as needed in the experiment, so as to meet the simulation of microgravity effects for different plant varieties and different experimental stages. At the same time, independent control also improves the flexibility of the experiment. Precise control helps to reduce errors in the experiment and improve the accuracy and reliability of experimental data.

[0015] Furthermore, it also includes: a controller, which is electrically connected to the power device and is used to control the start and stop, rotation speed and rotation time of the power device.

[0016] The beneficial effect of adopting the above further solution is that the controller, as the overall control of the gyrator, can centrally control the start and stop, rotation speed and rotation time of the power devices corresponding to multiple clamps on the gyrator. In particular, when adding modules, the number of chips in the controller can be increased to control each module separately.

[0017] Furthermore, the controller is provided with a touch screen and a switch button, the touch screen is used for manually triggering to set the rotation speed and rotation time of the power device, and the switch button is used for triggering to start the rotator.

[0018] The beneficial effect of adopting the above further solution is: the rotator is started by controlling the switch button, and the rotation speed and rotation time of the power device are set by manual triggering through the touch screen.

[0019] Furthermore, the movable light source includes: a movable light board and LED light tubes, the movable light board is arranged on the front side of the main box, and a plurality of LED light tubes are arranged on the movable light board at vertical intervals corresponding to the clamps on each module.

[0020] The beneficial effects of adopting the above further scheme are: the setting of the movable light board enables the LED lamp tube to be moved to the corresponding position as needed, meeting the experimental requirements of different plant varieties and plant heights, thereby improving the utilization rate of the equipment and the experimental efficiency; the LED lamp tube is arranged in the vertical direction and corresponds to the modules one by one, so that each plant sample in each module can obtain uniform and sufficient light, and is easy to maintain and replace later; the LED lamp tube as a light source has the advantages of high luminous efficiency, pure light color, and low light decay, further improving the uniformity and stability of light, and saving energy and protecting the environment.

[0021] Furthermore, a pulley is provided below the movable light panel for adjusting the distance between the movable light panel and the main box according to the height of plants of different species or varieties.

[0022] The beneficial effect of adopting the above further scheme is: the distance between the movable light panel and the main box is adjusted by the pulley, and the position of the movable light panel is adjusted according to the actual plant height of the plant variety, which can ensure that the light emitted by the LED lamp can irradiate plant samples of different species or varieties, meet the experimental requirements of plant heights of different plant varieties, and at the same time, the control of the distance is also conducive to improving the accuracy and reliability of the experimental data, solving the problem that the traditional rotating devices and random positioning mechanisms for simulating the microgravity effect of plants at home and abroad cannot adapt to different plant heights, and also prevents the light from being too strong or too weak, reducing the experimental errors caused by light differences.

[0023] Furthermore, the main box and the movable light source are covered by a black shielding member to ensure that all plant samples are exposed to light of the same intensity when rotating in the fixture.

[0024] The beneficial effect of adopting the above-mentioned further scheme is: maximizing the guarantee that all plant samples are exposed to light of the same intensity when rotating in the rotator, while reducing the interference of external light on the internal light source, ensuring that all plant samples are exposed to light of the same intensity from the movable light source when rotating in the rotator, which is conducive to ensuring a stable and consistent experimental environment and ensuring the accuracy of the experimental results.

[0025] A method for simulating microgravity effects on plants is also provided, using the above-mentioned cyclotron for simulating microgravity effects on plants, the steps comprising:

[0026] Choose an artificial climate chamber or plant cultivation room with controlled temperature and humidity, and level the base;

[0027] Fix the plant sample together with the plant culture container in the fixture of the main box, adjust the distance between the movable light panel and the main box according to the height of the plant, and turn on the LED light tube or choose not to turn it on to keep it dark;

[0028] Select the rotation speed and rotation time and start the experiment, turn on the switch button of the controller, touch the touch screen to set the rotation speed and rotation time and start, observe the normal operation of the gyrator, and then cover the outer side of the main box and the movable light panel with a black shield to isolate the uneven ambient light;

[0029] After reaching the set rotation time, the rotator automatically stops rotating and outputs a sound prompt, the switch button of the controller is turned off, and the plant sample is taken out to measure the relevant phenotype.

[0030] The beneficial effects of adopting the above further scheme are: by selecting an artificial climate chamber or plant culture room with controlled temperature and humidity, and leveling the rotator base, the stability and controllability of the experimental environment are ensured, which is conducive to reducing the influence of external factors on the experimental results; by adjusting the distance between the movable light panel and the main box, and covering with black flocking cloth to reduce external light interference, it is ensured that the plant samples are exposed to uniform lighting conditions or dark conditions during the rotation process, which is conducive to the accuracy and reliability of the experiment; compared with space experiments carried out on board spacecraft, this method can simulate the microgravity environment on the ground, greatly reducing the experimental cost and time cost, and is not restricted by time and place, thereby providing a simple and effective means for experiments on the microgravity effect of plants.

[0037] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0038] In the first aspect, the present invention provides a rotator for simulating the microgravity effect of plants, comprising: a main body box 1 and a movable light source 14, wherein the movable light source 14 is arranged on the front side of the main body box 1, and the position of the movable light source 14 is movable, so that the distance between the movable light source 14 and the main body box 1 is adjustable, adapted to the plant height of different species or varieties, and the movable light source 14 is used to provide illumination for the plant samples. The main body box 1 is composed of a plurality of modules connected in series, and the number of modules can be increased or decreased according to the number of plant samples required for the experiment, and customized according to the experimental requirements. A plurality of clamps 6 for placing and clamping plant culture containers are arranged on the module, and the plant culture containers are driven to rotate by the clamps 6 to simulate the microgravity environment. In the present embodiment, the side of the main body box 1 on which the plant samples are placed is the front side of the main body box 1, and the side is arranged opposite to the movable light source 14.

[0039] The movable light source 14 is arranged on the front side of the main box 1 so that the plant samples required for the experiment can be evenly illuminated, and when the light source is located on a single side of the plant sample required for the experiment, the light intensity received on this side is prevented from being higher than the light intensity received by the plants on the other side, thereby eliminating the influence of light on the experiment, and making the experiment only affected by rotating one variable. It can be imagined that as an alternative embodiment, two variables, illumination and rotation, can be introduced for experiment, and the setting position of the light source relative to the main box 1 can be changed during the experiment, for example, the light source can be set on the left side, right side or upper side of the main box 1, etc., to meet the needs of the experiment, and no further limitations are made here.

[0040] The above scheme overcomes the technical difficulty that the current domestic plant microgravity simulation device cannot conduct large-scale measurement and development tracking of mature plants. This rotator can realize batch testing of the growth and development response of various mature plants under microgravity, which is particularly suitable for processing multiple samples at the same time. By connecting the required number of modules in series, the number of samples required by the user can be achieved at a low cost, and each module can be operated independently, so that the same or different batches of samples can be subjected to the same or different gradient speeds of microgravity simulation effects at the same time, so as to achieve batch data collection under different experimental parameters; in addition, a dark environment can be realized to eliminate phototropic growth, and a single microgravity effect can be detected, or a top or side light source can be realized to induce phototropic growth and detect phototropic reactions under microgravity.

[0041] In some feasible embodiments, multiple groups of modules are vertically arranged on the base 7, that is, the modules are fixedly installed on the upper end surface of the base 7 perpendicular to the base 7, and handles are provided on both sides of the length direction of the base 7 for easy carrying. Multiple clamps 6 are evenly spaced in the vertical direction on each module, and plant culture containers can be placed in the clamps 6, wherein the clamps 6 on adjacent modules can correspond to each other one by one and be located on the same horizontal plane, or can be staggered with each other, which is not limited here. It can be imagined that in actual use, multiple groups of modules and bases 7 can be added side by side as needed.

[0042] In the above scheme, the setting of the base 7 provides stable support for multiple groups of modules, and the clamps 6 are evenly spaced on the modules so that the spacing and number of the clamps 6 can be freely adjusted according to experimental requirements, thereby adjusting the position and number of plant culture containers placed on the clamps 6; in addition, the setting of the clamps 6 on adjacent modules provides more layout options to meet different planting or experimental requirements; the movable light source 14 arranged on the front side enables the plants to obtain uniform light and reduces blind spots in light.

[0043] In the preferred scheme, the clamp 6 includes: a connecting platform connected to the module. In order to realize the connection of the clamp 6, an opening for installing the connecting platform is opened on the module, so that the connecting platform is installed in the opening and can rotate in the opening. The side of the connecting platform away from the movable light source extends to the side of the module away from the movable light source; a plurality of petals slightly expanding outward are extended from the side of the connecting platform close to the movable light source. During the experiment, the plant culture container is directly placed in the plurality of petals, and the plurality of petals can clamp the plant culture container to prevent the plant varieties from falling due to unstable clamping during rotation.

[0044] In the above scheme, the clamps 6 are connected to the modules independently, so the damage of a single clamp component does not affect the rotation of other clamps, and does not require overall maintenance and replacement; the multiple petals extending from the side of the connecting platform close to the movable light source provide a stable clamping environment for the plant culture container. The plant culture container is tightly clamped, effectively preventing the plant species from falling or being damaged due to unstable clamping during the rotation process, thereby ensuring the safety of the experiment and the accuracy of the data.

[0045] In order to drive the clamp 6 and the plant culture container to rotate, a power device is arranged on the side of the module away from the clamp 6. The power device is directly connected to the clamp 6 arranged on the extending module. Each clamp 6 is connected to a corresponding power device. The power device drives the clamp 6 to rotate and then drives the plant culture container on the clamp 6 to rotate together.

[0046] In the above scheme, each clamp 6 corresponds to a power device, which realizes independent control of a single plant culture container. This method makes it possible to adjust the rotation speed, direction and duration of each plant culture container individually as needed during the experiment, so as to meet the simulation of microgravity effects for different plant varieties and different experimental stages. At the same time, independent control also improves the flexibility of the experiment. Precise control helps to reduce errors in the experiment and improve the accuracy and reliability of experimental data.

[0047] In some feasible embodiments, a controller 8 is also provided on the rotator, and the controller 8 is electrically connected to the power device. Specifically, the controller 8 can be a circuit board, etc. The power device is installed behind the main box 1, and the power device is connected to the power slot of the controller 8 through wires. The controller 8 is used as the overall control device to control the start and stop, rotation speed and rotation time of the power devices corresponding to multiple clamps 6 on the entire rotator.

[0048] In the above scheme, the controller 8 serves as the overall control of the rotor, and can centrally control the start and stop, rotation speed and rotation time of the power devices corresponding to multiple clamps 6 on the rotor. Especially when adding modules, the number of chips in the controller can be increased to perform individual control of each module.

[0049] Meanwhile, a touch screen 9 and a switch button 10 are provided on the controller 8. The switch button 10 is a control button located on the controller 8 and is used to start the entire rotator; the touch screen 9 is used for manual triggering to set the rotation speed and rotation time of the power device.

[0050] In some feasible embodiments, the movable light source 14 includes: a movable light board 11 and an LED light tube 12. The movable light board 11 is used as the installation body of the LED light tube 12. During the experiment, the movable light board 11 is set at the front side of the main box 1 and is placed directly opposite the main box 1. Specifically, the LED light tube 12 is arranged in a vertical direction corresponding to the module, that is, the number of LED light tubes 12 is set corresponding to the number of modules, and the adjacent LED light tubes 12 are evenly spaced to provide light for the plant samples in each module.

[0051] In the above scheme, the setting of the movable light board 11 enables the LED lamp tube 12 to be moved to the corresponding position as needed, meeting the experimental requirements of plant heights of different plant varieties, thereby improving the utilization rate of the equipment and the experimental efficiency; the LED lamp tube 12 is arranged in the vertical direction and corresponds to the modules one by one, so that each plant sample in each module can obtain uniform and sufficient light, and is easy to maintain and replace later; the LED lamp tube 12, as a light source, has the advantages of high luminous efficiency, pure light color, and low light decay, further improving the uniformity and stability of light, and saving energy and protecting the environment.

[0052] Specifically, a pulley 13 is provided below the movable light panel 11, and the position of the movable light panel 11 relative to the main box 1 is adjusted by the pulley 13. The distance between the movable light panel 11 and the main box 1 can be adjusted according to the height of plants of different species or varieties.

[0053] When the heights of plants on adjacent modules are different, the modules are set corresponding to the movable light panels 11, that is, the movable light panels 11 can be reasonably set according to the heights of the plant samples tested on the modules and the number of LED light tubes 12 corresponding to the modules, and the movable light panels 11 corresponding to the low plant heights can be set closer to the main box 1. It can be imagined that, as a replaceable embodiment, the movable light panel 11 can be divided into multiple areas corresponding to each module of the main box 1, each area is provided with an LED light tube 12, and at least one retractable pull rod can be rotatably connected between each area, and the retractable pull rod is embedded between adjacent areas, and the adjacent areas are plugged in and out of the connection. If the plant varieties on adjacent modules are different in height, the adjacent areas can be separated, and one of the areas can be rotated to be close to or away from the main box 1 by the retractable pull rod, and the retractable pull rod can further adjust the distance of the area from the main box 1 through the multi-section retractable rod.

[0054] In the above scheme, the distance between the movable light board 11 and the main box 1 is adjusted by the pulley 13. The position of the movable light board 11 is adjusted according to the actual plant height of the plant variety, which can ensure that the light emitted by the LED lamp tube 12 can irradiate plant samples of different species or varieties, meeting the experimental requirements of plant heights of different plant varieties. At the same time, the control of the distance is also conducive to improving the accuracy and reliability of the experimental data, solving the problem that the traditional rotating devices and random positioning mechanisms for simulating the microgravity effect of plants at home and abroad cannot adapt to different plant heights, and also prevents the light from being too strong or too weak, reducing the experimental errors caused by light differences.

[0055] In some feasible embodiments, the main box 1 and the movable light source 14 are covered by a black shielding member, which maximizes the guarantee that all plant samples are exposed to light of the same intensity when rotating in the rotor, while reducing the interference of external light on the internal light source, ensuring that all plant samples are exposed to light of the same intensity from the movable light source 14 when rotating in the rotor, which is conducive to ensuring a stable and consistent experimental environment and the accuracy of the experimental results.

[0056] Embodiment 1

[0057] like Figure 1As shown, a rotator for simulating the microgravity effect of plants comprises: a main body box 1 and a movable light source 14, the movable light source 14 is arranged on the front side of the main body box 1, and the position of the movable light source 14 is movable, so that the distance between the movable light source 14 and the main body box 1 is adjustable, adapted to the plant height of different species or varieties, and the movable light source 14 provides illumination for the plant sample. In this embodiment, the main body box 1 is composed of four groups of modules in series, namely: module one 2, module two 3, module three 4 and module four 5. It can be imagined that the number of modules can be increased or decreased according to the number of plant samples required for the experiment, and customized according to the experimental requirements. Four clamps 6 for placing and clamping plant culture containers are arranged on each module, and the plant culture container is driven to rotate by the clamp 6 to simulate the microgravity environment. In this embodiment, the side of the main body box 1 where the plant sample is placed is the front side of the main body box 1, and the side is arranged opposite to the movable light source 14.

[0058] like Figure 1-4 As shown, four groups of modules are vertically arranged on a base 7, and handles are arranged on both sides of the base 7 in the length direction for easy carrying. Four clamps 6 are evenly spaced in the vertical direction on each module, that is, a total of 16 clamps 6 are arranged in a 4*4 arrangement, and plant culture containers are placed in the clamps 6.

[0059] like Figure 3-4 As shown, the clamp 6 includes: a connection platform connected to the module. In order to realize the connection of the clamp 6, an opening for installing the connection platform is provided on the module, so that the connection platform is installed in the opening and can rotate in the opening. The side of the connection platform away from the movable light source extends out of the module away from the movable light source; the side of the connection platform close to the movable light source extends to set four petals that expand slightly outward. During the experiment, the plant culture container is directly placed in the petal body, and the plant culture container is clamped by the petal body to prevent the plant variety from falling due to unstable clamping during rotation. When making, the clamp 6 can be constructed into a groove in the shape of a square by four iron plates, and a plant culture container of 8cm*8cm*8cm can be placed in the clamp 6.

[0060] In order to drive the clamp 6 and the plant culture container to rotate, a power device is provided on the side of the module away from the clamp 6. The power device can be, but is not limited to, a motor. The rotating shaft of the motor is connected to the side of the clamp 6 extending out of the module. Each clamp 6 is connected to a corresponding motor. The motor drives the clamp 6 to rotate and then drives the plant culture container on the clamp 6 to rotate together.

[0061] like Figure 1-3As shown, a controller 8 is also provided on the rotator, and the controller 8 is electrically connected to the power unit. Specifically, in the 4*4 modules of this embodiment, the power unit is installed behind the main box 1, and each power unit in a row of modules is connected to the same electrical slot of the controller 8 through a wire. The controller 8 is used as the overall control device to control the start and stop, rotation speed and rotation time of the power units corresponding to multiple clamps 6 on the entire rotator, wherein the speed adjustment range of the controller 8 is 0-80rph, and the rotation time adjustment range is 0-65536h.

[0062] Meanwhile, a touch screen 9 and a switch button 10 are provided on the controller 8. The switch button 10 is a control button located on the controller 8 and is used to start the entire rotator; the touch screen 9 is used for manual triggering to set the rotation speed and rotation time of the power device.

[0063] like Figure 1 As shown, the movable light source 14 includes: a movable light board 11 and an LED light tube 12. The movable light board 11 is used as the installation body of the LED light tube 12. During the experiment, the movable light board 11 is set at the front side of the main box 1 and is placed directly opposite the main box 1. Specifically, the LED light tube 12 is arranged in a vertical direction, and there are four columns of LED light tubes 12 corresponding to the module. Adjacent LED light tubes 12 are evenly spaced to provide light for the plant samples in each module.

[0064] Specifically, a pulley 13 is provided below the movable light panel 11, and the position of the movable light panel 11 relative to the main box 1 is adjusted by the pulley 13. The distance between the movable light panel 11 and the main box 1 can be adjusted according to the height of plants of different species or varieties.

[0065] In this embodiment, the main box 1 and the movable light source 14 are covered by a black shielding member. The black shielding member is made of but not limited to black flocking cloth, which makes it more convenient to obtain materials and can maximize the guarantee that all plant samples are exposed to the same intensity of light when rotating in the rotor, while reducing the interference of external light on the internal light source, ensuring that all plant samples are exposed to the same intensity of light from the movable light source 14 when rotating in the rotor, which is conducive to ensuring a stable and consistent experimental environment.

[0066] In a second aspect, the present invention further provides a method for simulating microgravity effects on plants, based on the above-mentioned cyclotron for simulating microgravity effects on plants, the steps comprising:

[0067] 1. Experimental environment selection: Select an artificial climate room or plant cultivation room with controlled temperature and humidity, and level the base 7; the base 7 of the rotator can be leveled with a level gauge. If the levelness of the base 7 does not meet the requirements, add padding to ensure that the upper end surface of the base 7 is level. By leveling the base 7, the plant species are completely perpendicular to the direction of gravity during the initial experiment, making the experimental results more accurate.

[0068] 2. Circuit connection: Connect the corresponding wires at the rear of the four modules of the main box 1 to the four sockets at the rear of the controller 8, connect the controller 8 to the power supply, and connect the LED lamp 12 to the power supply.

[0069] 3. Sampling: Fix the plant sample together with the plant culture container in the clamp 6 of the main box 1, adjust the distance between the movable light board 11 and the main box 1 according to the height of the plant, turn on the LED light tube 12 or choose not to turn on the LED light tube 12 to keep it dark; select parameters and start the experiment, turn on the switch button 10 of the controller 8, touch the touch screen 9 of the controller 8 to set the rotation speed and rotation time and start, observe the normal operation of the rotator, ensure that all the clamps 6 in the rotator rotate normally, and cover the outside of the main box 1 and the movable light board 11 with black flocking cloth to isolate the ambient light. The parameters include: the rotation speed and rotation time of the plant variety. The rotation direction is included in the rotation speed. The appropriate rotation speed and rotation time parameters can be selected according to the plant variety based on experience, and the experimental conditions can be flexibly controlled to meet the experimental needs of plants of different species or varieties.

[0070] 4. End of the experiment: After reaching the set rotation time, the rotator automatically stops rotating and outputs a sound prompt, the switch button 10 of the controller 8 is turned off, and the plant samples are taken out to measure the relevant phenotypes to evaluate the growth conditions of the plants in the simulated microgravity environment.
