Description

Technical Field

[0001] The present invention relates to the technical field of space suits, and in particular to a magnetically controlled bouncing dust removal microstructure space suit. Background Art

[0002] With the development of the space industry, the essential spacesuits for astronauts have been continuously improved and diversified. Spacesuits are enclosed microenvironments that ensure astronauts' safety and normal work. They are divided into intravehicular and extravehicular spacesuits based on their functions. Compared to intravehicular spacesuits, extravehicular spacesuits are more complex in structure and require higher levels of functionality, requiring protection from the vacuum, extreme temperatures, radiation, and lunar dust that can harm the human body. From landing to reentry, most lunar exploration activities are severely impacted by lunar dust. This affects the normal operation of spacecraft and also causes severe physiological reactions in astronauts, posing a threat to their health and safety. Lunar dust typically refers to fine particles of lunar soil, with a diameter of less than 20 μm. It primarily originates from weathered debris on the lunar surface. Its formation is closely related to space weathering, including meteorite and micrometeorite bombardment, solar wind and cosmic rays, and the significant diurnal temperature fluctuations. During landing, the lunar module was obstructed by external dust, significantly reducing its visibility. Furthermore, lunar dust can cause allergic reactions in the human body, resulting in symptoms such as tearing and coughing, and even respiratory distress in severe cases. Other effects include skin irritation, penetration, visual impairment, and mechanical and possible chemical irritation. Due to the impact of lunar micrometeorites, lunar dust contains nano-iron, which is potentially toxic to humans. Long-term inhalation can trigger cancers in various respiratory and internal organs. Lunar dust particles can easily enter spacesuits, and those adhering to the surface of spacesuit fabrics are difficult to remove using conventional methods. Lunar dust particles adhere to spacesuit surfaces through mechanical action or electrostatic adhesion. Mechanical action is due to the lunar vacuum. During solar weathering, lunar dust particles often develop irregular geometric shapes on their edges, resulting in a "spiky" appearance, which allows them to penetrate spacesuit fabrics. Electrostatic adhesion is due to the charging of lunar dust by solar wind plasma and the photoelectric effect, which increases its electrostatic adhesion. The abrasive effects of lunar dust particles adhering to the surface of a spacesuit can wear down the fabric and seals, significantly shortening its service life.

[0003] Therefore, it is urgent to provide a space suit with a dust removal function. Summary of the Invention

[0004] The purpose of the present invention is to provide a magnetically controlled bouncing dust removal microstructure space suit, which is used to remove lunar dust on the space suit and prevent the lunar dust from causing damage to astronauts.

[0015] Furthermore, there is a preferred embodiment in which the surface of the external magnetically controlled bouncing mechanism is coated with a conductive film, which is used to neutralize the electric potential of the lunar dust after coming into contact with the charged lunar dust, and the conductive film is connected to an external capacitor.

[0016] Furthermore, in a preferred embodiment, both the inner and outer magnetically controlled bouncing mechanisms are provided with an electromagnetic network layer inwardly, and the electromagnetic network layer is used to drive the magnetically controlled bouncing mechanism.

[0023] The present invention provides a microstructured spacesuit with magnetically controlled bouncing dust removal. This dust removal utilizes an external magnetically controlled bouncing mechanism. Specifically, after charged lunar dust contacts the conductive film on the surface of the external magnetically controlled bouncing mechanism, its electric potential is significantly reduced, even to zero. Under the action of an alternating magnetic field, the external magnetically controlled bouncing mechanism controls the magnetically controlled bouncing device to continuously convert kinetic energy and strain potential energy, separating a large number of larger lunar dust particles from the spacesuit through deformation and vibration. Small lunar dust particles are also captured using an internal magnetically controlled bouncing mechanism. Specifically, after the large lunar dust particles are separated from the spacesuit by the external magnetically controlled bouncing mechanism, a very small amount of small lunar dust particles still enter the spacesuit through the outermost layer. The internal magnetically controlled bouncing mechanism, under the action of the magnetic field, generates vibrations, driving the small lunar dust particles to move to the electromagnetic shielding layer and fix them in internal pores. The electromagnetic shielding layer requires regular functionality testing and timely replacement.

[0030] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details.

[0031] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

It should be noted that those skilled in the art may make various changes and improvements without departing from the scope of the present invention, and these are all within the scope of protection of the present invention.

[0032] Implementation method 1, see Figure 1 The present embodiment is described. The purpose of the present embodiment is to provide a magnetically controlled bouncing dust removal microstructure space suit, which is used to remove lunar dust on the space suit and prevent the lunar dust from causing damage to astronauts.

[0033] The space suit includes an electromagnetic coil and a magnetically controlled bouncing mechanism;

[0034] The magnetic control bouncing mechanism includes an outer magnetic control bouncing mechanism 2 and an inner magnetic control bouncing mechanism 5;

[0035] The external magnetically controlled bouncing mechanism 2 is sewn to the outermost layer of the space suit;

[0036] The inner magnetically controlled bouncing mechanism 5 is sewn between the outermost layer of the space suit and the thermal insulation layer;

[0037] The electromagnetic coil is used to control the inner and outer magnetically controlled bouncing mechanisms to perform vibration dust removal.

[0038] like Figure 1 As shown, the purpose of this embodiment is to control the magnetically controlled bouncing mechanism through electromagnetic coils to perform vibration dust removal. Furthermore, by adopting the external magnetically controlled bouncing mechanism 2 to remove large-particle lunar dust, and by adopting the internal magnetically controlled bouncing mechanism 5 to remove small-particle lunar dust, it is prevented that lunar dust of any particle size will cause harm to astronauts.

[0039] Implementation method 2, see Figures 1 to 3This embodiment is described. This embodiment specifically describes the structure of the magnetically controlled bouncing dust removal microstructure space suit described in the first embodiment above.

[0040] Specifically:

[0041] like Figure 1 and Figure 2 As shown, the electromagnetic coil controls the magnetically controlled bouncing mechanism for vibratory dust removal. The magnetically controlled bouncing mechanism comprises an outer magnetically controlled bouncing mechanism 2 and an inner magnetically controlled bouncing mechanism 5. Both mechanisms are constructed from multiple spliced ​​bouncing devices. The outer magnetically controlled bouncing mechanism is sewn to the outermost layer of the spacesuit, while the inner magnetically controlled bouncing mechanism is sewn between the outermost layer and the thermal insulation layer. The outer magnetically controlled bouncing mechanism 2 is coated with a conductive film 1, which neutralizes most of the charged lunar dust upon contact.

[0042] Furthermore, the conductive film 1 has a low resistivity and is connected to an external capacitor.

[0043] Furthermore, the magnetically controlled bouncing mechanism is in the shape of a regular hexagon, the circumscribed circle of the outer bouncing mechanism 2 is 5 mm in size, and the circumscribed circle of the inner bouncing mechanism 5 is 2 mm in size.

[0044] Furthermore, the bouncing device is composed of two different materials, namely NdFeB (neodymium iron boron) ferromagnetic particles and silica gel.

[0045] Further, such as Figure 3 As shown, the magnetically controlled bouncing device is composed of 6 magnetizable magnetic panels, specifically 6 magnetic pole panels 8 and respective folds 9.

[0046] The center of the outer magnetically controlled bouncing device is raised by 100 μm, and the center of the inner magnetically controlled bouncing device is raised by 50 μm.

[0047] Furthermore, the inner and outer magnetically controlled bouncing mechanisms are provided with electromagnetic network layers arranged inwardly to drive the magnetically controlled bouncing mechanisms.

[0048] Furthermore, the controllable magnetic field strength range of the electromagnetic network layer is -30 to 20 mT, wherein the magnetic field strength of the inner magnetically controlled bouncing mechanism 5 is controlled at -20 to 10 mT, the maximum value is selected in the external magnetic field strength range, the working magnetic field strength change frequency is 40 Hz, and the waveform is a rectangular wave.

[0049] Furthermore, the inner and outer electromagnetic network layers 6 are connected to different power sources, and the power intensity connected to the outer magnetically controlled bouncing mechanism 2 is greater than the power intensity connected to the inner magnetically controlled bouncing mechanism 5 .

[0050] Furthermore, an electromagnetic shielding layer 4 is provided between the outer electromagnetic network layer 3 and the inner magnetically controlled bouncing mechanism 5 to prevent the magnetic fields generated when the inner and outer electromagnetic network layers are working from interfering with each other.

[0051] Furthermore, the electromagnetic shielding layer 4 has a honeycomb pore structure with a pore size not exceeding 20 μm, and has the function of trapping tiny lunar dust.

[0052] Furthermore, a vibration buffer layer 7 is provided in the heat insulation layer to reduce the vibration impact on the internal instruments of the space suit and the astronauts.

[0053] After the above-mentioned space suit is set up, the storage of strain potential energy is achieved through the magnetically controlled bouncing device. Specifically: 6 magnetic panels are magnetized to align the polarity of the NdFeB ferromagnetic particles, and the magnetism has the same permanent magnetization direction, enabling them to flip under the influence of an external magnetic field, thereby driving the deformation of the entire structure. The folds are composed of a mixture of silicone and polydimethylsiloxane (PDMS) and act as the elastically deformable part of the structure. Compared with the magnetic panels of the structure, the modulus of the folds is smaller, which makes them easier to bend and stretch. During the transition between stable states, the folds can store or release a large amount of strain potential energy.

[0054] Dust is removed through an external magnetically controlled bouncing mechanism. Specifically, after the charged lunar dust comes into contact with the conductive film on the surface of the external magnetically controlled bouncing mechanism, the electric potential is greatly reduced or even reduced to 0. Under the action of the alternating magnetic field force, the external magnetically controlled bouncing mechanism controls the magnetically controlled bouncing device to continuously convert kinetic energy and strain potential energy, and separates a large number of larger particles in the lunar dust from the space suit through deformation and vibration.

[0055] It is captured through the internal magnetic control bouncing mechanism. Specifically: after the large-particle lunar dust is separated from the space suit by the external magnetic control bouncing mechanism, a very small number of small-particle lunar dust still enters the space suit through the outermost layer. The internal magnetic control bouncing mechanism vibrates under the action of the magnetic field force, driving the small particles of lunar dust to move to the electromagnetic shielding layer and fix them in the internal pores. The electromagnetic shielding layer needs to be regularly tested for functionality and replaced in a timely manner.
