Description

Technical Field

[0001] This invention relates to the field of aerospace engineering, and in particular to a space breeding experimental module. Background Technology

[0002] The concept of space agriculture originated from breeding needs and the development of modern aerospace technology. With breakthroughs in aerospace technology, manned spacecraft launches, and the establishment of space stations worldwide, scientists began considering finding habitable spaces beyond Earth and utilizing space cultivation to solve the problem of food security. Furthermore, crop seeds can undergo genetic mutations under the mutagenic effects of the space environment, acquiring special functions such as high yield, high quality, and disease resistance, thereby increasing crop production, enriching agricultural resources, and gradually forming a new field of scientific research. Space agriculture, also known as space breeding, is a new breeding technology that involves sending crop seeds or mutagenic materials into space aboard recoverable spacecraft or high-altitude balloons, utilizing the unique mutagenic effects of the space environment to induce seed mutations, and then returning them to Earth to cultivate new crop varieties.

[0003] The space environment is characterized by weak magnetic fields, microgravity, strong radiation, wide temperature range, high vacuum, and ultra-cleanliness, making it difficult to fully simulate on Earth. Furthermore, due to the vibrations of moving components such as flywheels and solar panels, as well as the complex geomagnetic and radiation environment in near-Earth orbit, traditional spacecraft struggle to meet the conditions of extremely low microgravity and extremely weak magnetic fields in orbit. Therefore, given the urgent needs of space agriculture development, developing a spacecraft that can achieve controllable maintenance of extremely weak magnetic fields and ultra-low microgravity, optimize the utilization of the near-Earth radiation environment, and construct a suitable experimental environment for space agriculture is of great significance.

[0072] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are merely some embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without creative effort.

[0073] In describing embodiments of the present invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" express orientations or positional relationships based on the orientations or positional relationships shown in the relevant drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0074] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0075] Combination Figure 1 and Figure 2As shown, according to one embodiment of the present invention, a space breeding test module includes: a support unit 1 and a breeding chamber 2 disposed in the support unit 1; in this embodiment, the support unit 1 provides the main support and corresponding arrangement space for the breeding chamber 2, wherein the support unit 1 has a hollow first receiving cavity 11, and a gripping device 12 is disposed in the first receiving cavity 11. In this embodiment, the breeding chamber 2 is located in the first receiving cavity 11, and the breeding chamber 2 is disposed opposite to the gripping device 12; wherein the breeding chamber 2 is a hollow spherical structure, and its external dimensions are smaller than the cavity dimensions of the first receiving cavity 11. In this embodiment, the gripping device 12 is used to lock the breeding chamber 2 in non-experimental stages (such as the stage of launch, orbit change, and recovery of the test module) to fix the position of the breeding chamber 2 in the first receiving cavity 11; the gripping device 12 is used to release the breeding chamber 2 in the experimental stage to allow the breeding chamber 2 to levitate freely in the first receiving cavity 11.

[0076] With the above configuration, the present invention can provide a reliable and stable ultra-low microgravity environment for the breeding chamber 2 by using the first receiving cavity 11 provided by the support unit, so that the breeding chamber 2 can be freely released in the first receiving cavity 11, so that the breeding chamber 2 is in a state of free suspension in space.

[0077] With the above-mentioned configuration, the present invention uses the gripping device 12 to fix and release the breeding chamber 2, which can flexibly control the suspension state of the breeding chamber 2 according to the flight state of the entire test cabin, ensuring the reliability and stability of the breeding experiment process during the flight of the test cabin along a pure gravity orbit.

[0078] like Figure 3 As shown, according to one embodiment of the present invention, the first receiving cavity 11 includes a breeding chamber arrangement cavity 111 and a fixed mounting cavity 112; in this embodiment, the breeding chamber arrangement cavity 111 and the fixed mounting cavity 112 are connected and coaxial. In this embodiment, the breeding chamber arrangement cavity 111 is a spherical cavity, and the breeding chamber 2 is disposed within the breeding chamber arrangement cavity 111; wherein, by setting the breeding chamber arrangement cavity 111 as a spherical cavity, it is easier to reliably control the interval between the breeding chamber arrangement cavity 111 and the breeding chamber 2, which is beneficial to ensuring the safe operation of the breeding chamber 2 and avoiding collisions.

[0079] In this embodiment, the gripping device 12 is fixedly supported in the fixed mounting cavity 112. The gripping device 12 is installed in a coaxial manner with the fixed mounting cavity 112, thereby ensuring that the gripping device 12 and the entire first receiving cavity 11 are in a coaxial position. Therefore, the gripping device 12 can be used to grip and fix the breeding chamber 2, which can accurately adjust the suspension position of the breeding chamber 2 in the first receiving cavity 11. This has a beneficial effect on ensuring the accurate position of the breeding chamber 2 and avoiding collision between the breeding chamber 2 and the first receiving cavity 11.

[0080] like Figure 3 As shown, according to one embodiment of the present invention, the gap between the outer side of the breeding chamber 2 and the inner side of the breeding chamber arrangement cavity 111 is 5cm to 20cm. This arrangement effectively ensures that the breeding chamber 2 has sufficient microgravity suspension space within the breeding chamber arrangement cavity 111, and effectively avoids collisions.

[0081] Combination Figure 3 , Figure 4 and Figure 5 As shown, according to one embodiment of the present invention, the gripping device 12 includes: a telescopic base 121, a connecting seat 122 disposed at the movable end of the telescopic base 121, a plurality of gripping members 123 rotatably connected to the connecting seat 122, and a damping buffer 124 for connecting to the driving gripping members 123. In this embodiment, the plurality of gripping members 123 are evenly distributed along the circumference of the connecting seat 122; wherein, the bottom end of the gripping member 123 is rotatably connected to the upper end of the connecting seat 122; the fixed end of the damping buffer 124 is rotatably connected to the lower end of the connecting seat 122, and its telescopic end is rotatably connected to the gripping member 123. In this embodiment, a first rotating connecting seat is provided on the outer side of the bottom end of the gripper 123. Correspondingly, a first rotating shaft for connecting to the first rotating connecting seat is provided on the outer edge of the upper end of the connecting seat 122. The first rotating shaft is fixedly connected to the upper end of the connecting seat 122 by a support member. Specifically, the support member is set as an inclined long rod, so that the first rotating shaft has a certain gap relative to the connecting seat 122, thereby facilitating the connection with the first rotating connecting seat and allowing the bottom end of the gripper 123 to have sufficient room for movement. Similarly, a second rotating connecting seat is provided at intervals on the side of the gripper 123 where the first rotating connecting seat is provided, thereby realizing the rotating connection with the telescopic end of the damping buffer 124. On the connecting seat 122, in order to realize a large range of motion of the gripper 123, a radially protruding annular support can be further provided, and a third rotating connecting seat for rotating connection with the fixed end of the damping buffer 124 can be provided on the outer edge of the annular support.

[0082] like Figure 6As shown, in this embodiment, the telescopic base 121 includes: a plurality of nested and slidable sleeves 1211, a lead screw 1212 for driving the plurality of sleeves 1211 to extend and retract sequentially, and a motor 1213 for driving the lead screw 1212 to rotate; wherein, the extension of each sleeve 1211 is controlled sequentially by the motor 1213 driving the lead screw 1212 to rotate, wherein the innermost sleeve 1211 is used to connect to the connecting seat 122, thereby realizing the telescopic control of the gripper 123. The method of driving with the lead screw 1212 and sleeves 1211 can adopt existing mature structures, which will not be described in detail here.

[0083] In this embodiment, the damping buffer 124 can be an electrically operated damping buffer, which can extend and retract through the power controller to achieve a buffering effect on the gripper 123 at different tilt angles.

[0084] In this embodiment, four gripping members 123 can be provided, and four corresponding damping buffers 124 can also be provided to buffer each gripping member 123, thereby avoiding rigid impact between the gripping member 123 and other structures.

[0085] In this embodiment, along the direction from the upper end to the lower end of the gripper 123, the position where the telescopic end of the damping buffer 124 connects to the gripper 123 is aligned with the position where the lower end of the gripper 123 connects to the connecting seat 122, and there is a gap between them. This arrangement effectively ensures that the force applied by the damping buffer 124 to the gripper 123 is aligned with the rotational position of the lower end, which is more beneficial for ensuring the installation and operational accuracy of the gripper 123.

[0086] In this embodiment, the gripper 123 has a spherical panel-like structure. The width of the lower end of the gripper 123 is reduced on both sides by removing portions, thus avoiding interference between adjacent grippers 123. Furthermore, the lower end of the gripper 123 has a beveled surface located on the side away from the first rotating connecting seat. This beveled surface prevents interference between the end of the gripper 123 and the sidewall of the connecting seat 122 during rotation, ensuring reliable and stable operation of the entire gripper 123.

[0087] In this embodiment, the spherical radius of the gripper 123 is the same as the spherical radius of the breeding chamber arrangement cavity 111, so that the surface of the gripper 123 can match the surface of the breeding chamber arrangement cavity 111.

[0088] With the above configuration, by setting the gripper 123 as a spherical panel structure, the present invention can make the surface shape of the gripper 123 match the shape of the inner wall of the breeding chamber arrangement cavity 111. In particular, during the breeding experiment, when the gripper 123 is separated from the breeding chamber 2, the gripper 123 can be retracted to a position that abuts against the breeding chamber arrangement cavity 111, thereby effectively avoiding the gripper 123 from occupying space and interfering with the breeding chamber 2, so as to ensure the smooth progress of the breeding experiment.

[0089] With the above configuration, by setting the gripper 123 as a spherical panel structure, the surface of the gripper 123 can more easily come into contact with the outer surface of the breeding chamber 2, which is more beneficial to the reliable and stable gripping of the breeding chamber 2. In particular, the synchronous action of multiple grippers 123 can also conveniently realize the accurate adjustment of the position of the breeding chamber 2, so that the position of the breeding chamber 2 is accurate and stable when it is released next time.

[0090] Combination Figure 3 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, according to one embodiment of the present invention, the support unit 1 includes: an upper bracket 1a, a lower bracket 1b, a pose camera 1c, a magnetic induction coil 1d, and a heating element 1e. In this embodiment, the upper bracket 1a and the lower bracket 1b are detachably connected to form a first receiving cavity 11 between the upper bracket 1a and the lower bracket 1b; in this embodiment, the pose camera 1c, the magnetic induction coil 1d, and the heating element 1e are respectively mounted on the side wall of the first receiving cavity 11. The pose camera 1c is used to detect the pose of the breeding room 2 to ensure that the breeding room 2 is always in a safe and accurate position, especially in the suspended state. The pose camera 1c can detect the pose and position of the breeding room 2 in real time to ensure the safety of the breeding room 2. In order to realize the pose detection of the breeding room 2 by the pose camera 1c, the marker 21 is set on the outside of the breeding room 2 for easy detection. The marker 21 is set on the outside of the breeding room 2 opposite to each of the pose cameras 1c. Then, the corresponding pose can be accurately obtained by acquiring the image of the marker 21 captured by each pose camera 1c through a visual detection algorithm.

[0091] In this embodiment, the upper support 1a and the lower support 1b are made of heat-treated permalloy. Through this arrangement, by using heat-treated permalloy upper support 1a and lower support 1b, which are interconnected to form the first receiving cavity 11, excellent magnetic shielding can be achieved, realizing comprehensive magnetic shielding of the breeding room 2.

[0092] Combination Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, the upper support 1a includes: a first housing 1a1 and a plurality of connecting legs 1a2; wherein, the first housing 1a1 is generally cylindrical, and the first housing 1a1 is provided with a first cavity portion 1a11. In this embodiment, the opening of the first cavity portion 1a11 is located on the lower side of the first housing 1a1, and it extends in an upward direction. In this embodiment, the first cavity portion 1a11 is part of the breeding chamber arrangement cavity 111, wherein the first cavity portion 1a11 and the first housing 1a1 are coaxially arranged. In this embodiment, a plurality of first grooves are also provided at equal intervals at the edge of the first cavity portion 1a11. The provided first grooves can effectively reduce the weight of the first housing 1a1 to increase the effective load of the entire test chamber, and can also facilitate the abutment and limiting of the gripping member 123 to effectively simplify the positioning difficulty of the breeding chamber 2. Specifically, when it is necessary to fix the position of the breeding chamber 2, the telescopic base 121 can be extended. At this time, the gripping member 123 moves towards the breeding chamber 2 and moves the breeding chamber 2 towards the side wall of the first cavity portion 1a11, so that the breeding chamber 2 is fixed by the gripping member 123 against the side wall of the first cavity portion 1a11. In this embodiment, the end of the gripping member 123 just abuts against the bottom of the first groove. Since the damping buffer 124 can effectively avoid the rigid impact between the gripping member 123 and the first groove, and under the driving action of the telescopic base 121, the gripping member 123 is buffered and supported until the position of the breeding chamber 2 is fixed. When it is necessary to release the breeding chamber 2, the telescopic base 121 can be retracted to the initial position. It should be noted that when it is necessary to adjust the position of the breeding chamber 2 in the first accommodating cavity 11, the position of the support unit 1 relative to the breeding chamber 2 can be adjusted by means of the propulsion section 8 of the test chamber when the breeding chamber 2 is in a free state, so as to achieve flexible control of the suspension state of the breeding chamber 2.

[0093] In this embodiment, multiple connecting legs 1a2 are evenly spaced along the circumference of the first housing 1a1. One end of each connecting leg 1a2 is fixedly connected to the outer side of the first housing 1a1, while the other end extends away from the first housing 1a1. Each connecting leg 1a2 includes a first support member, a second support member, and a connecting member. In this embodiment, the first and second support members are both elongated plates. The upper end of the first support member is aligned with the lower edge of the first housing 1a1, and the upper end of the second support member is fixedly connected perpendicularly to both the outer side of the first housing 1a1 and the outer side of the first support member. In this embodiment, the lower ends of both the first and second support members are fixedly connected to the connecting member. The connecting member is also a plate-shaped structure, horizontally arranged and perpendicular to both the first and second support members, to facilitate the fixed connection between the connecting member and the lower bracket 1b. In this embodiment, the connection between the upper bracket 1a and the lower bracket 1b can be achieved using threaded connections, snap-fit ​​connections, or other methods.

[0094] like Figure 10 As shown, in this embodiment, the lower support 1b includes: a support base plate 1b1, a first hollow cylinder 1b2 and a second hollow cylinder 1b3 fixedly supported on the support base plate 1b1; in this embodiment, the second hollow cylinder 1b3, the first hollow cylinder 1b2 and the support base plate 1b1 are arranged coaxially in sequence; the hollow portion of the first hollow cylinder 1b2 forms a fixed mounting cavity 112; the second cavity portion 1b31 of the second hollow cylinder 1b3 is connected to the fixed mounting cavity 112; and a telescopic base 12 is located in the fixed mounting cavity 112. The bottom of 1 is directly fixed to the support base plate 1b1. The opening size of the fixed mounting cavity 112 connected to the second cavity portion 1b31 is smaller than the size of the gripper 123 in the unfolded state. Thus, when the gripper 123 is in the unfolded state, on the one hand, the shape of the gripper 123 can be used to abut against the side wall of the second cavity portion 1b31, and on the other hand, the bottom end of the gripper 123 can at least partially close the opening, thereby ensuring that the breeding room 2 can only move within the breeding room arrangement cavity 111.

[0095] In this embodiment, the first hollow cylinder 1b2 is generally a straight cylindrical structure, while the second hollow cylinder 1b3 is generally a spherical ring structure. In this embodiment, the connecting leg 1a2 is detachably connected to the support base plate 1b1, and the second hollow cylinder 1b3 is arranged opposite to the first shell 1a1; wherein, the first cavity portion 1a11 and the second cavity portion 1b31 are connected to form a spherical breeding chamber arrangement cavity 111.

[0096] In this embodiment, to increase the connection stability between the first hollow cylinder 1b2 and the support base plate 1b1, the first hollow cylinder 1b2 can be further fixed to the support base plate 1b1 by setting multiple ribs at equal intervals, so as to improve the connection reliability.

[0097] By setting up the upper support 1a and the lower support 1b coaxially and detachably, the structural components can be easily installed and arranged, and the breeding chamber 2 can be easily removed after the experiment, thus improving the ease of use of the invention.

[0098] With the above-described configuration, the combination of the upper support 1a and the lower support 1b allows for better installation of the upper support 1a and the lower support 1b with other necessary system components. For example, various system components (such as test monitoring equipment, force sensors, thermal sensors, data storage devices, communication devices, etc.) can be arranged on the multiple connecting legs 1a2 and the support base plate 1b1. This effectively utilizes the structure and space of the support unit 1, thereby improving the overall space utilization rate of the invention and reducing the overall volume of the test chamber.

[0099] Combination Figure 3 and Figure 9 As shown, according to one embodiment of the present invention, a pose camera 1c and a plurality of magnetic induction coils 1d are disposed on the sidewall of the first cavity portion 1a11. In this embodiment, the pose camera 1c is embedded at the farthest end of the first cavity portion 1a11 from the second cavity portion 1b31, that is, the pose camera 1c is located at the intersection of the first cavity portion 1a11 and the axis of symmetry of the first cavity portion 1a11. The plurality of magnetic induction coils 1d are arranged at intervals, and one of them is coaxial with the pose camera 1c.
