Description

Technical Field

[0001] This utility model relates to the field of aerospace equipment, and in particular to a near-space seed capsule. Background Technology

[0002] The unique and complex extreme environmental conditions of near space (specifically, the airspace at an altitude of 20–100 km above the Earth's surface), characterized by high radiation, low temperature, dryness, and low air pressure, can be compared to the environment of early Earth and the surface environment of modern Mars, making it a natural laboratory for conducting research in geobiology and astrobiology. In recent years, researchers have successively discovered numerous microorganisms at altitudes of 20–41 km in near space, indicating the existence of an unknown biosphere there. With advancements in airship technology and the development of experimental methods and equipment, a series of new progress has been made in areas such as near space biodiversity and its environmental adaptation mechanisms. This provides new breakthroughs for research into astrobiological issues such as the upper boundary of Earth's biosphere, the limits of life's survival, life in Mars-like environments, interstellar transmission of life, and planetary protection.

[0003] Near-space biological experiments, such as near-space seed exposure experiments that expose seeds to light and radiation from space, offer numerous opportunities, high flexibility in distribution and retrieval, low cost, and abundant resources for experimental equipment, making them an important component of space biological science research. Comparative studies with biological experiments in near-Earth orbit can further enhance our understanding of how complex and extreme environments affect organisms and provide a basis for exploring near-space biological communities.

[0004] Currently, there is still a gap in domestic research on near-space seed exposure experiments. Existing seed biological exposure devices often have drawbacks such as a limited number of local installation stations, a limited variety of samples that can be carried, non-reusability, and high maintenance costs. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a near-space seed capsule that can slowly open its lid upon reaching a predetermined near-space altitude, exposing the seeds inside the capsule to the external environment. This allows for the study of the effects of different types of radiation on seed germination and growth, thus providing experimental evidence for future space agriculture.

[0006] According to one aspect of the present invention, a near-space seed chamber is provided, comprising a chamber body in which multiple seed containers and a motor are installed. The motor is connected to the middle of a rotating shaft via a reducer. The front and rear ends of the rotating shaft are respectively connected to two left-right extending supports. The two supports are respectively connected to the top surface of a cover, and the cover is rotatable to cover the top of the chamber body or to move away from the chamber body to expose each of the seed containers.

[0007] In some embodiments, the reducer is connected to the rotating shaft via a coupling. This is advantageous because it further describes the connection method between the reducer and the rotating shaft, allowing for better control of the shaft's rotation.

[0008] In some embodiments, an extension plate is formed on the side of the cabin, and the reducer and the rotating shaft are mounted on the extension plate. The advantage of this is that the extension plate facilitates the installation of the reducer and the rotating shaft.

[0009] In some embodiments, the front and rear ends of the rotating shaft are respectively mounted on the extension plate via two supports. The advantage is that the specific mounting method of the rotating shaft is further described.

[0010] In some embodiments, the lid is made of a transparent material. The advantage of using a transparent material allows most light to pass through, providing conditions for the seeds to receive light and radiation from the universe.

[0011] In some embodiments, a notch is formed in the lid, and the motor is located in the notch. The advantage of this is that the motor can pass through the notch when the lid rotates, thus ensuring that the lid can rotate smoothly. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figure 1-4As shown, the seed compartment mainly includes a compartment 1, which is roughly square in shape, and multiple seed containers 2 are installed in it. The seed containers 2 are fixedly installed on the compartment 1 by screws and are used to hold seeds.

[0019] A motor 3 is installed on the chamber 1, and the rotor of the motor 3 extends to the outside of the chamber 1 and is connected to a reducer 4. The reducer 4 is connected to the middle of a rotating shaft 5, and the two ends of the rotating shaft 5 (the front and rear ends) are respectively connected to two supports 6 extending to both sides (the left and right sides). The two supports 6 are respectively connected to one side (the top surface) of a cover 7 by multiple screws. Thus, when the motor 3 is operating, the reducer 4, the rotating shaft 5 and the two supports 6 can drive the cover 7 to flip, so that the cover 7 covers the top of the chamber 1 or rotates away from the chamber 1 to expose the seed container 2.

[0020] Preferably, the reducer 4 is connected to the middle of the rotating shaft 5 via a coupling.

[0021] The seed compartment is 400mm wide, the compartment 1 is 370mm long, and the cover 7 is 320mm long. When the cover 7 is fully open, the total length of the seed compartment is 675mm, and when the cover 7 is fully closed, the total height of the seed compartment is 71mm.

[0022] Preferably, an extension plate 9 is formed on the side of the cabin 1, the reducer 4 is mounted on the extension plate 9, and the front and rear ends of the rotating shaft 5 are respectively mounted on the extension plate 9 through two supports 10, without affecting the rotation of the rotating shaft 5.

[0023] Preferably, the lid 7 is made of a transparent material, allowing most of the light to pass through, thus providing conditions for the seeds to receive light and radiation from the universe.

[0024] More preferably, a notch 11 is formed on the cover 7. When the cover 7 is closed, the motor 3 is located in the notch 11, so that the motor 3 can pass through the notch 11 when the cover 7 rotates, thereby ensuring that the cover 7 can rotate smoothly.

[0025] Before launch, the seed capsule is sealed to ensure the safety of the internal environment and the protection of the seeds. When the weather balloon flies to the predetermined near-space altitude, the motor 3 starts, and the cover 7 is slowly opened through the reducer 4, rotating shaft 5 and two supports 6. At this time, the seeds in the seed container 2 are exposed to the external environment and can come into contact with various high-energy radiation and other environmental factors in space. This can be used to study the effects of different radiations on seed germination and growth, thus providing experimental evidence for future space agriculture.

[0026] The seed capsule is made of high-strength, lightweight materials to ensure airtightness and durability in extreme environments, and its surface is specially treated to resist oxidation and corrosion, adapting to the harsh conditions of long-term exposure to adjacent space.

[0027] This seed chamber is designed to operate normally in environments as low as -70 degrees Celsius and under low pressure, ensuring that the seeds inside are not damaged by extreme temperature and pressure conditions. The chamber is equipped with specialized temperature and humidity monitoring equipment to monitor and record environmental changes in real time for subsequent data analysis. Even under extreme conditions, the biological materials inside the chamber can still maintain a suitable growth environment.

[0028] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
