Description

Technical Field

[0001] The present invention relates to the field of in-situ penetration detection of extraterrestrial celestial bodies, and particularly to a penetration buffer damping device. Background Art

[0002] For the exploration and research of extraterrestrial celestial bodies, the physical characteristic parameters of deep planetary regolith are the key to deducing the evolution mechanism of the Earth, the origin of Earth's water, the distribution law of cosmic components, etc. Penetrating the warhead into or through the celestial body for detection by penetration is a common method. Among them, the kinetic energy penetration detector is a detection method with a small kinetic energy demand cost and a large detection depth, but it needs to balance the detection depth and the requirement of satellite communication for detection data.

[0003] Currently, the international community has adopted a split scheme to carry out kinetic energy penetration detection, such as MARs-96 of Russia and DeepSpace-2 of the United States. However, the above-mentioned schemes all adopt different outer diameters, directly leaving the communication part on the planet's surface by using different diameters, and completely lack buffer performance, which exacerbates the anti-mechanical conditions of electronic components. For the buffer of kinetic energy penetration, currently, mainly two methods of honeycomb aluminum deformation energy absorption and airbag buffer energy absorption are adopted. Honeycomb aluminum deformation energy absorption requires a large space and stroke, and the absorption capacity is fixed after design. Since it does not have adaptability to kinetic energy, it is necessary to design a sufficient absorption margin, resulting in an increase in weight cost. The airbag buffer method conducts buffer design through the elasticity of the airbag, but the airbag will rebound with the same energy after buffering, and this process is difficult to control, which is not conducive to the stability of the attitude of the equipment stored on the planet's surface.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0025] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] In an exemplary embodiment, the present invention provides a penetration buffering and damping device, as Figure 1 shown, including a penetrator 1. A magnetic conductor 2 is disposed around the non-penetrating end of the penetrator 1. A resistance-increasing plate 3 connected to the penetrator 1 is provided on the lower end surface of the magnetic conductor 2. A magnetic source structure 4 for generating a magnetic force on the magnetic conductor 2 is disposed inside the non-penetrating end of the penetrator 1.

[0027] Specifically, the magnetic source structure 4 includes a magnetic source and a magnetic source controller. When the penetrator 1 comes into contact with the penetrated medium 5, an overload acceleration is generated, and the magnetic source controller turns on the magnetic source.

[0028] When the magnetic source is turned on, the magnetic conductor 2 generates a reverse resistance force on the magnetic source structure 4 to buffer the penetrator 1. The magnitude of the resistance force is adapted to the penetration kinetic energy of the penetrator 1.

[0029] As Figure 2As shown, the penetrator 1, the magnetic conductor 2, the drag-increasing plate 3, and the magnetic source structure 4 are an integral structure. During specific use, the integral structure will penetrate into the medium 5 to be penetrated under the action of a certain kinetic energy.

[0030] Furthermore, the outer diameter of the drag-increasing plate 3 is larger than that of the penetrator 1. Due to the difference in the outer diameters of the drag-increasing plate 3 and the penetrator 1, when the drag-increasing plate 3 contacts the medium 5 to be penetrated, the two impacted bodies will separate, and at this time, the penetrator 1 and the magnetic conductor 2 will also separate. Meanwhile, under the action of factors such as overload, the magnetic source controller will be opened. After the magnetic source controller is opened, the magnetic source inside the penetrator 1 will release a certain magnetic field, and this magnetic field will interact with the magnetic conductor 2. At this time, the magnetic conductor 2 will be subject to the magnetic force interaction 6, which will impede the moving magnetic source in the penetrator 1, thereby buffering the penetrator 1.

[0031] Furthermore, the magnitude of the resistance is related to the relative motion speed, the 6664540 magnetic field intensity, the magnetic permeability, etc. The greater the relative motion speed, the greater the resistance; the smaller the relative motion, the smaller the resistance. By virtue of this effect, a certain buffering effect will be produced on the penetrator, and the buffering effect will be adapted to the penetration kinetic energy through the relative motion speed.

[0032] After the magnetic source and the magnetic conductor 2 are completely separated, the magnetic force interaction 5 will also disappear. The drag-increasing plate 3 and the magnetic conductor 2 will stay on the planet surface, and the penetrator 1 will continue to penetrate under the action of the residual kinetic energy. After the penetration is completed, physical property detection and analysis will be carried out at the corresponding position.

[0033] In one example, for a penetration buffering and damping device, the magnetic conductor 2 and the drag-increasing plate 3 are an integrated structure. Since the magnetic conductor 2 and the drag-increasing plate 3 are an integrated structure, during the buffering process, under the constraint of the interaction force between the magnetic source and the magnetic conductor 2, the possibility of the magnetic conductor 2 and the drag-increasing plate 3 remaining on the star surface bouncing is greatly reduced, avoiding phenomena such as the jumping probability, and ensuring the attitude of the equipment staying on the star surface.

[0034] In one example, for a penetration buffering and damping device, the magnetic conductor 2 is cylindrical and covers the penetrator 1. Specifically, the magnetic conductor 2 entirely envelopes the penetrator 1 so as to generate electromagnetic induction. Connection methods such as shear pins, screws, and pins can be used, and the specific connection method can be designed according to the specific situation and will not be elaborated here.

[0035] In one example, for a penetration buffering and damping device, the penetration end of the penetrator 1 is bullet-shaped.

[0036] In one example, for a penetration buffering and damping device, the drag-increasing plate 3 is a hollow circular plate sleeved on the penetrator 1.

[0037] In one example, an impact buffering and damping device, the resistance increasing plate 3 is in a deployed structure or a metamorphic cell structure, and can be formed by unfolding from a contracted state at a large diameter position.

[0038] The above specific embodiments are detailed descriptions of the present invention. It cannot be determined that the specific embodiments of the present invention are only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions and substitutions can still be made, which should all be regarded as belonging to the protection scope of the present invention.
