Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0030] An embodiment of the multipurpose engineering structure protection structure of the present application comprises at least two protection units, and the plurality of protection units are detachably connected. As shown in the figure, each protection unit comprises an upper plate 1 and a lower plate 2. A plurality of end-closed elastic tube bodies 3 are arranged between the upper plate 1 and the lower plate 2. The plurality of elastic tube bodies 3 are arranged in layers to form a honeycomb structure. The tube walls of the elastic tube bodies 3 on two corresponding surfaces of the honeycomb structure are connected with the upper plate 1 and the lower plate 2. Specifically, the elastic tube bodies 3 are adhered to the upper plate 1 and the lower plate 2 by vulcanization. The material of the upper plate 1 and the lower plate 2 is carbon fiber, which has the characteristic of high strength. Different media are filled in the adjacent two layers of elastic tube bodies 3 in the honeycomb structure. A detachable connecting assembly for connecting with another protection unit is arranged on the protection unit. Figure 1 Specifically, in order to ensure that the protection unit will not tilt in the horizontal and vertical directions when impacted, the embodiment further comprises a mounting bracket. The mounting bracket comprises a bracket base 7 arranged at the bottom of the lower plate 2. Specifically, a groove matching the bracket base 7 is formed at the bottom of the lower plate 2. The bracket base 7 is placed in the groove. A bracket rod 8 vertically arranged on the bracket base 7 is arranged. The bracket rod 8 is arranged in the mounting hole 4 formed in the center of the upper plate 1 and the lower plate 2. The end of the bracket rod 8 protruding out of the upper plate 1 is detachably connected with a bracket cap. The bracket base 7 and the bracket rod 8 are made of carbon fiber material, and the bracket cap 9 is made of rubber material.
[0031] Specifically, one of the two adjacent layers of elastic tube bodies 3 in the honeycomb structure is filled with liquid medium, and the other is filled with gas medium. One of the two adjacent layers of elastic tube bodies 3 is composed of a plurality of elastic tube bodies 3 arranged at intervals, and the other is composed of a plurality of elastic tube bodies 3 arranged continuously. Specifically, as shown in the figure, the black layer of the honeycomb structure in the embodiment is filled with liquid medium, and the white layer is filled with gas medium. The black layer is formed by a plurality of elastic tube bodies 3 arranged at intervals, and the white layer is formed by a plurality of elastic tube bodies 3 arranged continuously. The medium can also be a molten medium according to the need. Since water and air are convenient to obtain, the liquid medium used in the embodiment is water, and the gas medium is air.
[0032] Figure 1 Specifically, one of the two adjacent layers of elastic tube bodies 3 in the honeycomb structure is filled with liquid medium, and the other is filled with gas medium. One of the two adjacent layers of elastic tube bodies 3 is composed of a plurality of elastic tube bodies 3 arranged at intervals, and the other is composed of a plurality of elastic tube bodies 3 arranged continuously. Specifically, as shown in the figure, the black layer of the honeycomb structure in the embodiment is filled with liquid medium, and the white layer is filled with gas medium. The black layer is formed by a plurality of elastic tube bodies 3 arranged at intervals, and the white layer is formed by a plurality of elastic tube bodies 3 arranged continuously. The medium can also be a molten medium according to the need. Since water and air are convenient to obtain, the liquid medium used in the embodiment is water, and the gas medium is air.Figure 1 As shown, in order to support the upper plate 1 on both sides of the honeycomb structure, black layers are connected together on both sides of the honeycomb structure in the vertical direction.
[0033] Specifically, the detachable connecting assembly includes connecting pieces and connecting holes 6, which are arranged on the four corners of the upper plate 1 and the lower plate 2. When one protective unit is connected to another protective unit at the top, the upper plate of one protective unit is connected to the lower plate 2 of another protective unit through the connecting pieces and the connecting holes 6. When one protective unit is connected to another protective unit at one side, the connecting seat 5 of one protective unit is connected to the connecting seat 5 of another protective unit through the connecting pieces and the connecting seat 5.
[0034] Specifically, in order to prevent the medium in other elastic tube bodies 3 from being discharged when one elastic tube body 3 is damaged, causing the protective device to fail, a one-way valve is arranged at the end of each elastic tube body 3 in this embodiment.
[0035] Specifically, the elastic tube body 3 is made of cord fabric, which is a composite of rubber and metal wire. Specifically, cord fabric is commonly used in automobile tires.
[0036] Specifically, the lower plate 2 is spaced apart from the end face of the honeycomb structure by a mounting distance of the connecting bolts and the connecting seat 5.
[0037] Specifically, the cross section of the elastic tube body 3 is a regular hexagon, a square, a triangle or a circle. In order to make the elastic tube body 3 more firmly bonded to the upper plate 1 and the lower plate 2, the elastic tube body 3 with a regular hexagonal or square cross section is selected in this embodiment, so that the contact surface of the elastic tube body 3 and the upper plate 1 and the lower plate 2 is larger and the bonding is more reliable.
[0038] Specifically, in use:
[0039] Step one: first place the mounting bracket at the position to be protected, and then insert the bracket rod 8 of the mounting bracket into the mounting hole 4 of the upper plate 1 and the lower plate 2 of the protective unit (in the Figure 3 state).
[0040] Step two: open the air one-way valve on the honeycomb structure in the protective unit (in the Figure 3 state), and the corresponding honeycomb air bag is filled with air; the corresponding air bag is filled with water. The state of the honeycomb structure after being inflated and filled with water is shown in Figure 1 . At this time, due to the water filling, the weight of the protective structure body increases suddenly, and the lower plate 2 is compacted due to gravity, and the bracket rod 8 prevents the protective structure body from tilting.
[0041] Step three: cover the bracket cap 9.
[0042] Step four: based on the above steps, the installation of the single protective structure module is completed. When the expansion area is needed, multiple protective structure modules can be arranged according to the predetermined position, and the modules are bolted through the small holes of the connecting seat 5. When the height of the protective structure needs to be increased, the expansion connection can be made through the inter-plate connecting holes 6.
[0043] The specific implementation scenario is:
[0044] Implementation scenario one: the invasion explosive ammunition sets the layer fuse to attack the interior of a certain floor of the building; the main working mode of the layer fuse of the invasion explosive ammunition is: the acceleration and impact vibration sensor is arranged in the warhead, when it penetrates through a floor, the sensor will output a certain characteristic impact signal, and after judgment, it counts a layer, and so on. The protective structure can be flexibly arranged in different floors according to the need. In this implementation scenario, the beneficial effects mainly lie in two aspects: first, when the penetrating ammunition penetrates through the protective structure, the impact signal generated is similar to that when it penetrates through the floor, which can deceive the fuse to count the number of layers, so that the floor to be protected can be protected, and the fuse can be started to detonate the warhead in advance; second, the main body of the protective structure is a honeycomb structure, the curtain cloth and the filling water can effectively reduce the speed of the penetrating ammunition (which is basically the same as the effect of the floor), and then reduce the penetration ability of the penetrating ammunition to the building structure, so as to realize the key protection of the floor to be protected.
[0045] Implementation scenario two: the invasion explosive ammunition sets the cavity fuse to attack the interior of underground fortifications, airplane shelters, etc. The protective structure can be flexibly arranged, and in emergency situations, it can be installed on the ground of the protective fortification, and multiple layers can be vertically arranged, that is, multiple protective units are placed on another protective unit, and then one protective unit is connected to another protective unit through the connecting hole 6 and the bolt, that is, the protective structure is formed, so that when the ammunition is attacked, most of the energy of the invasion explosive ammunition is dissipated on the protective structure, and cannot penetrate the permanent protective layer of the underground fortification itself, that is, multiple protective units are vertically arranged. In addition, the honeycomb structure has certain anisotropy (that is, the adjacent two layers of elastic tubes of the honeycomb structure are filled with different media, that is, due to the difference in medium, the impact force of the bullet on the bullet will be different during the penetration process), so that the penetrating ammunition will produce a certain deflection angle during the penetration process, thereby reducing the threat of the bullet to the underground fortification, and further improving the protection ability.
[0046] The third implementation scenario is that the whole-burst ammunition sets the contact fuze to attack the top of the building; the protection structure is arranged flexibly on the roof or hung on the outer wall of the building, that is, the connecting seat 5 of every two protection units is connected by bolts to form an overall flat protection structure; when the whole-burst ammunition contacts or explodes in the near field, the shock wave and the fragment damage elements act on the upper / lower plate of the protection structure, and the water-filled honeycomb structure has good shock wave absorption and buffering effect, and can greatly reduce the speed of the fragments, thereby effectively protecting the local and overall structure of the building.
[0047] Other implementation scenarios: the honeycomb structure of the protection unit has good vibration damping effect; when the floor is paved in the room, the ground vibration and ground impact signals can be well attenuated, and the fragile equipment and personnel can be protected;
[0048] The protection structure is hung on the outside of the large equipment, and has good resistance effect on the shock wave and the fragments; for example, the protection structure is hung on the outside of the light armored vehicle and the command vehicle, and the fragments of the fragmentation bomb can be prevented.
[0049] In summary, the multi-purpose engineering structure protection structure provided by the embodiment of the application sets the honeycomb structure composed of a plurality of elastic pipe bodies between the upper plate and the lower plate, and the adjacent pipe bodies are filled with different media; when the fragments invade, due to the anisotropic characteristics of the honeycomb structure, the fragments will produce a certain deflection angle during the penetration process, thereby changing the trajectory of the fragments, and further reducing the threat of the fragments to the protection body; at the same time, during the fragment invasion process, the honeycomb structure fills the elastic pipe body with water and gas to form a buffer structure, which can buffer the impact force when invaded, thereby further reducing the threat of the fragments to the protection body, and making the protection effect better.
[0050] The above only describes the preferred embodiments of the application and is not intended to limit the application; any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
