Description

Technical Field

[0001] The 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 aerospace industry, space suits, which are essential for astronauts, are also constantly improving and diversifying. Space suits are enclosed microenvironments that ensure the safety of astronauts' lives and normal work. They can be divided into cabin space suits and extravehicular space suits according to their functions. Compared with cabin space suits, extravehicular space suits have more complex structures and higher functional requirements. They need to protect the vacuum, high and low temperatures, radiation, and lunar dust in space from the harm to the human body. During the entire period from landing to return, most of the lunar exploration activities were seriously affected by lunar dust. Lunar dust affects the normal operation of spacecraft, and also causes astronauts to have strong physiological stimulation reactions, endangering the life, health and safety of astronauts. Lunar dust usually refers to fine lunar soil particles with a particle size of less than 20μm. It mainly comes from weathered debris on the lunar surface. Its cause is closely related to space weathering such as meteorites, micrometeorite bombardment, solar wind and cosmic rays, and huge day and night temperature differences. The lunar module was blocked by external dust during the landing process, which significantly reduced its visibility. In addition, lunar dust causes allergic reactions in human functions, causing allergic symptoms such as tears and coughing, and even breathing difficulties in severe cases. It also includes skin irritation, penetration, visual damage, mechanical and possible chemical irritation. Due to the effect of micrometeorites on the lunar surface, there is nano-iron in lunar dust, which may be potentially toxic to the human body. Long-term inhalation can easily induce cancer of various respiratory tracts and internal organs. Moon dust particles can also easily enter the interior of the space suit, and the moon dust particles attached to the surface of the space suit fabric are difficult to remove by ordinary means. Moon dust particles are attached to the surface of the space suit through mechanical action or electrostatic adhesion. The mechanical action is due to the vacuum environment of the moon. In the process of solar weathering, the edge morphology of the moon dust particles is mostly irregular geometric shape, that is, the moon dust particles have a "spike" morphology, which enables them to enter the space suit fabric. Electrostatic adhesion is due to the charging effect of solar wind plasma and photoelectric effect on the moon dust, which causes the moon dust to be charged, thereby increasing the electrostatic adhesion of the moon dust. The abrasive effect of the moon dust particles attached to the surface of the space suit will wear the fabric and sealing mechanism of the space suit, greatly shortening its service life.

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

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

It should be noted that, for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope 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 magnetically controlled bouncing mechanism comprises an outer magnetically controlled bouncing mechanism 2 and an inner magnetically controlled 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 heat 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 an external magnetically controlled bouncing mechanism 2 to remove large-particle lunar dust, and by adopting an internal magnetically controlled bouncing mechanism 5 to remove small-particle lunar dust, it is possible to prevent lunar dust of any particle size from causing 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 is used to control the magnetic control bouncing mechanism to perform vibration dust removal. The magnetic control bouncing mechanism includes an outer magnetic control bouncing mechanism 2 and an inner magnetic control bouncing mechanism 5; both the inner and outer magnetic control bouncing mechanisms are spliced ​​together by multiple bouncing devices, the outer magnetic control bouncing mechanism is sewn to the outermost layer of the space suit; the inner magnetic control bouncing mechanism is sewn between the outermost layer of the space suit and the thermal insulation layer. The outer magnetic control bouncing mechanism 2 is coated with a conductive film 1, which will neutralize most of the electric potential of the lunar dust after contacting with the charged lunar dust.

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

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

[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 six magnetizable magnetic panels, specifically six magnetic pole panels 8 and respective folds 9.

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

[0047] Furthermore, the inner and outer magnetically controlled bouncing mechanisms are provided with electromagnetic network layers 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 of the external magnetic field strength range is selected, 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, the outer electromagnetic network layer 3 and the inner magnetically controlled bouncing mechanism 5 are provided with an electromagnetic shielding layer 4 to prevent the magnetic fields formed 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 20um, 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 vibration impact on the internal instruments of the space suit and the astronauts.

[0053] After the above-mentioned space suit setting, 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, allowing them to flip under the influence of an external magnetic field, thereby driving the deformation of the entire structure. The creases 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 creases is smaller, which makes them easier to bend and stretch. During the transition between stable states, the creases can store or release a large amount of strain potential energy.

[0054] Dust is removed through an external magnetically controlled bouncing mechanism. Specifically, when 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 magnetically controlled bouncing mechanism. Specifically, after the large-particle lunar dust is separated from the space suit by the external magnetically controlled bouncing mechanism, a very small number of small-particle lunar dust still enters the space suit through the outermost layer. The internal magnetically controlled 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.
