A military anti-amphibious combat vehicle landing device and anti-landing equipment

Abstract

The present invention provides a military anti-amphibious vehicle landing device, comprising a drive device, a transmission device, a support portion, and a hook-shaped mechanism. The support portion is fixedly mounted on the fixed portion, the drive device is fixedly mounted on one side of the support portion, the bottom end of the transmission device is fixedly connected to the drive device, the top end of the transmission device is fixedly connected to the top end of the support portion, and the hook-shaped mechanism is fixedly mounted on the top end of the support portion. When an external force acts on the drive device, the drive device can be compressed in the height direction, driving part of the transmission device to move downward, thereby causing part of the transmission device to reciprocate. The vibration generated by the reciprocating motion of the transmission device can rapidly liquefy the surface of the sand and soil, forming a fluid state, rendering an amphibious vehicle traveling on the sand and soil unable to continue moving. At the same time, the downward compression of the drive device causes the amphibious vehicle to sink, and the hook-shaped mechanism can be engaged in the gap between the track teeth, achieving an anti-landing effect.

Description

Technical Field

[0001] The present application relates to the field of anti-landing technology, and in particular to a military anti-amphibious combat vehicle landing device and anti-landing equipment. Background Art

[0002] Sand liquefaction refers to the phenomenon in which saturated loose silt and fine sand suddenly break down under vibration and transform into a liquid state. This change in state occurs due to increased pore water pressure and decreased effective stress. The mechanism of sand liquefaction is that saturated loose silt and fine sand tend to move and densify under vibration, shifting the stress load from the sand skeleton to the water. Due to the poor permeability of silt and fine sand, pore water pressure increases dramatically. When the pore water pressure reaches the total stress value, the effective stress drops to zero, the particles become suspended in water, and the sand liquefies.

[0003] Liquefaction caused by reciprocating loading or shear (also known as reciprocating liquefaction) typically manifests as liquefaction damage in saturated sand foundations and slopes during major earthquakes. This phenomenon can also occur under dynamic forces such as machine foundation vibration and blasting. When saturated sand is subjected to reciprocating shear, shear tension generally occurs when the shear strain is very low, causing an increase in pore water pressure. However, as the shear strain increases, sands with medium or higher densities begin to experience shear dilatation. This occurs because sand particles tumble against each other under high shear strain, increasing the volume of the skeleton. This causes a corresponding decrease in pore water pressure, while the effective stress and shear resistance increase, inhibiting further deformation. After repeated reciprocating shear, the accumulation of shear contraction and pore water pressure in the low shear strain range can lead to liquefaction. When saturated sand is sufficiently loose, it can exhibit "infinite" flow deformation.

[0004] When war or foreign invasion breaks out, areas near the coast or lakeshore often become important targets for countries and regions surrounded by seas or lakes. Preventing foreign enemies from landing on the coast or lakeshore becomes one of the important means of preventing foreign invasion. Summary of the Invention

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way.

[0036] On the one hand, the present application provides a military anti-amphibious combat vehicle landing device, such as Figure 1As shown, the military anti-amphibious vehicle landing device includes a drive device 21, a transmission device 22, a support portion 23, and a hook mechanism 24. The support portion 23 is fixedly mounted on the fixed portion 1 and is used to support the hook mechanism 24 and the drive device 22. The drive device 21 is fixedly mounted on one side of the support portion 23, the bottom end of the transmission device 22 is fixedly connected to the drive device 21, and the top end of the transmission device 22 is fixedly connected to the top end of the support portion 23. The hook mechanism 24 is fixedly mounted on the top end of the support portion 23.

[0037] In one embodiment, if Figure 2 As shown, the driving device 21 includes a driving mechanism 211 and a first protective cover 212 mounted on the outside of the driving mechanism 211. The driving mechanism 211 is fixedly mounted on the fixed portion 1. The first protective cover 212 can prevent the driving mechanism 211 from contacting a large amount of sand and soil, thereby preventing the driving mechanism 211 from failing. The first protective cover 212 includes a top wall and a side wall. A first through hole is provided on the top wall of the first protective cover 212. The transmission device 22 is fixedly connected to the driving mechanism 211 through the first through hole. In order to better prevent sand and soil from entering the interior of the driving device 21, a first sealing portion is provided at the first through hole for sealing the first protective cover 212. Exemplarily, the first sealing portion is a silicone ring or a rubber ring. The side wall of the first protective cover 212 is made of a compressible accordion plate. In the height direction of the driving device 21, the side wall of the first protective cover 212 is compressible.

[0038] In this embodiment, the drive mechanism 211 can be one or more first springs 213 arranged side by side. The top ends of the first springs 213 are fixedly connected to the transmission device 22. Under normal conditions, the first springs 213 are in a normally extended state. To increase the compressible distance, the first springs 213 can be conical springs. Conical springs have a higher compression ratio than ordinary springs and can achieve substantial flattening. The first protective cover 212 is mounted on the exterior of the drive mechanism 211. The top wall of the first protective cover 212 contacts the top of the first spring 213. When an external force is applied to the first protective cover 212 and the first spring 213, the first protective cover 212 and the first spring 213 can be compressed under the action of the external force.

[0039] In one embodiment, if Figure 3As shown, the driving device 21 includes a first spring 213, a protective cover 214 disposed outside the first spring 213, and a lifting portion 215 disposed on top of the first spring 213 and sleeved with the protective cover 214. The protective cover 214 is fixedly mounted on the fixing portion 1, the first spring 213 is disposed inside the protective cover 214, a second through-hole is defined on the top wall of the protective cover 214, the size of the second through-hole being adapted to the size of the lifting portion 215, the lifting portion 215 partially sleeves within the protective cover 214 through the second through-hole, and the bottom of the lifting portion 215 is fixedly connected to the top of the first spring 213. When an external force acts on the lifting portion 215, the lifting portion 215 can compress the first spring 213, and the lifting portion 215 moves toward the interior of the protective cover 214 following the first spring 213.

[0040] In order to prevent sand from entering the interior of the protective cover 214 and hindering the compression of the first spring 213, a second sealing portion is provided at the second through hole for sealing the protective cover 214. Exemplarily, the second sealing portion is a silicone ring or a rubber ring.

[0041] like Figure 4 As shown, the transmission device 22 includes a transmission mechanism 221 and a second protective cover 222 that is sleeved on the outside of the transmission mechanism 221 and fixedly connected to the support portion 23. The transmission mechanism 221 includes a rack 223 whose bottom end is fixedly connected to the driving device 21, a gear 224 that meshes with the rack 223, and a cam mechanism 225 that is coaxially arranged with the gear 224. When the driving device 21 is compressed under the action of an external force, the driving device 21 drives the rack 223 to move downward, thereby driving the gear 224 to move upward relative to the rack 223. When the external force acting on the driving device 21 disappears, the driving device 21 returns to its initial state, and the driving device 21 drives the rack 223 to move upward, thereby driving the gear 224 to move downward relative to the rack 223. In other words, the driving device 21 can drive the gear 224 to reciprocate on the rack 223.

[0042] Continue to refer Figure 4 The cam mechanism 225 includes a cam 2251 coaxially arranged with the gear 224, a sleeve 2252 arranged at the top of the support portion 23, a piston rod 2253 arranged in the sleeve 2252 and adapted to the inner cavity of the sleeve 2252, and a connecting rod 2254. One end of the connecting rod 2254 is hinged to the piston rod 2253, and the other end of the connecting rod 2254 contacts and cooperates with the cam 2251. Preferably, in order to facilitate the arrangement of the sleeve 2252 at the top of the support portion 23, the cam mechanism 225 further includes an L-shaped connecting arm 2255, one end of the L-shaped connecting arm 2255 is fixedly connected to the sleeve 2252, and the other end of the L-shaped connecting arm 2255 is fixedly connected to the top of the support portion 23.

[0043] Under the action of an external force, the driving device 21 is compressed, driving the rack 223 downward, thereby rotating the gear 224 meshing with the rack 223, and further rotating the cam 2251 and gear 224. Since the top of the piston rod 2253 is disposed within the sleeve 2252, and the bottom of the piston rod 2253 is hinged to the top of the connecting rod 2254, the rotation of the cam 2251 causes the piston rod 2253 to perform piston motion within the sleeve 2252. When the external force disappears, the driving device 21 returns to its initial state, driving the rack 223 upward, thereby rotating the gear 224 meshing with the rack 223 in the opposite direction, and further rotating the cam 2251 and gear 224, causing the piston rod 2253 to perform piston motion within the sleeve 2252. In other words, the driving device 21 can drive the piston rod 2253 to perform piston motion within the inner cavity of the sleeve 2252.

[0044] To prevent transmission mechanism 221 from coming into contact with large amounts of sand and soil, and thus prevent failure, a second protective cover 222 is mounted on the outside of transmission mechanism 221. The bottom wall of second protective cover 222 is fixedly mounted to support portion 23, which supports second protective cover 222. A third through-hole and a fourth through-hole are respectively defined in the top and bottom walls of second protective cover 222. A rack 223 passes through the fourth through-hole. The bottom end of rack 223 is fixedly connected to drive mechanism 21, and the top end of rack 223 is located within second protective cover 222. A piston rod 2253 passes through the third through-hole. The top of piston rod 2253 is disposed within sleeve 2252, and the bottom of piston rod 2253 is hingedly connected to connecting rod 2254. To better prevent sand and soil from entering the interior of second protective cover 222, a third sealing portion and a fourth sealing portion are respectively provided at the third through-hole and the fourth through-hole to seal second protective cover 222. Exemplarily, the sealing portions are silicone rings or rubber rings.

[0045] In order to make the second protective cover 222 more stable, Figure 1 As shown, the support portion 23 and the L-shaped connecting arm 2255 can also pass through the top wall and / or bottom wall of the second protective cover 222, and the support portion 23 and the L-shaped connecting arm 2255 are partially arranged inside the second protective cover 222, and the support portion 23, the L-shaped connecting arm 2255 are fixedly connected to the second protective cover 222 at the connection point to support the second protective cover 222.

[0046] like Figure 1 As shown, a hook mechanism 24 is fixedly provided at the top of the support portion 23. Preferably, the height of the hook mechanism 24 is higher than the height of the transmission device 22. In one embodiment, as shown in FIG. Figure 4As shown, the hook mechanism 24 includes a fixing rod 241 and a plurality of hook portions 242 fixedly disposed at the top of the fixing rod 241. Preferably, the top of the fixing rod 241 is conical, and the included angle between the fixing rod 241 and the hook portion 242 in the vertical direction is an acute angle. The number of hook portions 242 can be multiple, and illustratively, the number of hook portions 242 is four, and the four hook portions 242 are evenly disposed at the top of the fixing rod 241. The fixing rod 241 and the hook portion 242 together form a hook mechanism 24 similar to an anchor. Under the action of gravity, the hook mechanism 24 can penetrate into the track of the amphibious combat vehicle, and the hook portion 242 can be stuck in the gap between the grouser teeth of the track, thereby preventing the amphibious combat vehicle from moving forward.

[0047] In another embodiment, Figure 5 As shown, the hook mechanism 24 further includes a second spring 243, one end of the hook portion 242 is hinged to the top of the fixed rod 241, the other end of the hook portion 242 is fixedly connected to one end of the second spring 243, and the other end of the second spring 243 is fixedly set on the fixed rod 241. The angle between the fixed rod 241 and the hook portion 242 in the vertical direction is an acute angle. Figure 5 Shown and referenced Figure 6 The second spring 243 is in a normally extended state when not in operation. When an external force is applied to the hook portion 242, the hook portion 242 can compress the second spring 243, and the hook portion 242 moves closer to the fixing rod 241. The hook mechanism 24 as a whole shrinks laterally and becomes sharp, making it easier for the hook portion 242 to penetrate into the track of the amphibious combat vehicle, thereby preventing the amphibious combat vehicle from moving forward.

[0048] In order to increase the lateral contraction of the hook mechanism 24, the second spring 243 can be a conical spring. The conical spring has a higher compression ratio and can be basically flattened, so that the lateral contraction of the hook mechanism 24 reaches the optimal state, which is more conducive to the hook part 242 penetrating into the track of the amphibious combat vehicle.

[0049] The second aspect of the present application provides an anti-landing device, wherein a plurality of military anti-amphibious combat vehicle landing devices are fixedly arranged on a fixed part 1, such as Figure 7 As shown, several military anti-amphibious combat vehicle landing devices are arranged in sequence along a preset straight line direction and fixed on the fixed part 1. Of course, they can also be arranged in other forms, for example, arranged along a curve, a circle, etc. The arrangement of the military anti-amphibious combat vehicle landing devices is not fixed, and only a few examples are listed here.

[0050] like Figure 7 and Figure 8As shown, the anti-landing device also includes a movable portion 3, which is disposed on top of the drive device 21. The movable portion 3 can be fixed or movably disposed on top of the drive device 21. Each military anti-amphibious vehicle landing device is provided with a movable portion 3. For ease of installation, multiple military anti-amphibious vehicle landing devices can also share a single movable portion 3. The movable portion 3 is used to withstand external forces applied to the military anti-amphibious vehicle landing device. Preferably, the top surface area of ​​the movable portion 3 is larger than the top surface area of ​​the drive device 21. The movable portion 3 can increase the force-bearing area. Driven by the drive device 21 of the military anti-amphibious vehicle landing device, the movable portion 3 can be raised and lowered in the vertical direction.

[0051] like Figure 9 As shown, when in use, the anti-landing equipment is pre-buried in the sand. The distance between the top of the anti-landing equipment and the surface of the sand can be used to obtain the anti-liquefaction strength of the anti-landing sand according to the triaxial test. Then, based on the liquefaction judgment standard and the size characteristics of the military anti-amphibious combat vehicle landing device, the optimal pre-buried depth of the military anti-amphibious combat vehicle landing device that can ensure the liquefaction of the sand is obtained.

[0052] When an amphibious combat vehicle travels over a sandy surface pre-embedded with anti-landing equipment, the vehicle's gravity acts on movable portion 3. This force, in turn, compresses drive mechanism 21, causing the vehicle's head to sink and preventing it from advancing, achieving a preliminary anti-landing effect. Simultaneously, the compression of drive mechanism 21 drives transmission mechanism 221, causing piston rod 2253 to perform piston motion within sleeve 2252. As the amphibious combat vehicle continues to move forward, the drive mechanism, freed from the force of gravity, rapidly rebounds, driving piston rod 2253 to perform piston motion again. The vibrations generated by the movement of piston rod 2253 cause the surface of the sandy soil to rapidly liquefy, forming a fluidized state. The fluidized sandy soil is unable to provide the traction required for the amphibious combat vehicle's forward motion, rendering the tracked vehicle immobile and achieving the desired anti-landing effect.

[0053] At the same time, the bearing capacity of the liquefied sand surface becomes weaker, and the amphibious combat vehicle sinks under the action of gravity. When the amount of sinking is large, the track of the amphibious combat vehicle will contact the hook mechanism 24 of the military anti-amphibious combat vehicle landing device. Since the hook mechanism 24 is in the shape of an anchor, or the hook mechanism 24 can be laterally contracted under the action of the gravity of the amphibious combat vehicle, the hook mechanism 24 can be easily stuck in the gap between the teeth, and the hook mechanism 24 is fixedly connected to the support part 23, and the support part 23 is fixedly set on the fixed part 1. Therefore, when the hook mechanism 24 is stuck in the track, the amphibious combat vehicle will be unable to move forward, causing the amphibious combat vehicle to paralyze in place, achieving the effect of anti-landing of the amphibious combat vehicle.

[0054] In this application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that an article or device comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such article or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the article or device comprising the element.

[0055] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0056] Obviously, those skilled in the art may make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if such changes and modifications of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such changes and modifications.
