Description

Technical Field

[0001] The present invention relates to the field of building structures, in particular to building protection, and more particularly to a deep-sea island reef shelter, and specifically to an anti-fall protection device used inside a deep-sea island reef shelter. Background Art

[0002] The shelters on deep-sea islands and reefs are used to resist damage from external explosives and other weapons during wartime. As important military defense facilities, deep-sea island and reef shelters undertake the important task of protecting the safety of personnel and materials during wartime. However, in the face of the complexity and high intensity of modern warfare, shelters face unprecedented challenges. Under the action of the explosion shock wave, the shelter will not only suffer direct impact damage, but also cause a series of secondary disasters due to the destruction of the internal structure.

[0003] First, the blast wave will cause the rubble inside the shelter to collapse. When the external explosives explode, the huge energy generated will instantly act on the shelter structure, causing rubble and debris from the walls, roof and other parts to fly, posing a serious threat to the personnel in the shelter.

[0004] Secondly, the deep-sea island and reef shelter will also suffer bending and shear failure under the action of the explosion shock wave. Bending failure usually occurs in the middle of the wall. Due to the action of the explosion shock wave, the middle of the wall will be subjected to a large bending moment, causing cracks or even fractures in the wall. Shear failure mainly occurs at the end of the wall. Due to the shear force generated by the explosion shock wave, the end of the wall is prone to shear slippage or fracture, further weakening the overall structural strength of the shelter.

[0005] Therefore, it is necessary to design a new protective device that can effectively resist the damage to internal personnel caused by the rock collapse caused by the explosion shock wave of external explosives and other weapons. Summary of the invention

[0053] The implementation of the present invention is described in detail below in conjunction with preferred embodiments.

[0054] like Figures 1 to 6 As shown, the present invention proposes an anti-fall protection device for the interior of a deep-sea island reef shelter, comprising an anti-fall steel plate frame 1, a buffer device 2, and a plurality of energy dissipation devices 3. The device mainly protects the anti-fall steel plate frame 1 in multiple directions through the buffer device 2 and the plurality of energy dissipation devices 3, significantly improving the overall protection capability of the anti-fall steel plate frame 1, effectively resisting damage from external explosives and other weapons, and preventing rock fragmentation, bending, and shear damage caused by explosion shock waves.

[0055] See also Figures 1 to 4 The anti-fall steel plate frame 1 is formed by two groups of vertical protective steel plates 101 and one group of horizontal protective steel plates 102. The two groups of vertical protective steel plates 101 are double-layer steel plates. A first gap 5 is reserved between the double-layer steel plates. The two groups of vertical protective steel plates 101 are vertically symmetrically arranged on both sides of the inner wall of the shelter 100, and a second gap 6 is reserved between each group of vertical protective steel plates 101 and the shelter 1.

[0056] The transverse protection steel plate 102 is horizontally overlapped on the top of the two sets of vertical protection steel plates 101. A predetermined distance is also reserved between the transverse protection steel plate 102 and the shelter 100, so as to receive the broken stones collapsed from the shelter 100 and prevent the broken stones from collapsing into the shelter 100.

[0057] In some embodiments, the transverse protective steel plate 102 is a movable steel plate. The movable steel plate is slidably mounted on the top of the two sets of vertical protective steel plates 101. The transverse protective steel plate 102 can be pulled out horizontally along the inside of the shelter 100, suitable for receiving the gravel and transporting it to the outside of the shelter 100, thereby preventing the gravel from accumulating inside the shelter 100 and reducing safety hazards.

[0058] In some embodiments, the anti-falling steel plate frame 1 abuts against the sheltering portion 100 through the support member 103 in the second gap 6, thereby enhancing the connection stability between the anti-falling steel plate frame 1 and the sheltering portion 100, making the entire structure more solid and reliable.

[0059] In some embodiments, see Figure 3 , Figure 4 , the support member 103 is a group of support plates extending from the top of each group of vertical protective steel plates 101 toward the second gap 6. Furthermore, each group of support plates includes at least two horizontal steel plates arranged at intervals. A plurality of gravel holes of different sizes are provided on a horizontal steel plate below a group of support plates arranged on the top of the vertical protective steel plates 101, so that the gravel collapsed from the sheltering part 100 can fall to the bottom of the second gap 6, which is convenient for timely cleaning of the gravel later. Or each group of support plates includes two horizontal steel plates arranged at intervals and a pad, wherein the pad is welded between the two horizontal steel plates along the side of the sheltering part 100, and the support plate is abutted against the sheltering part 100 by the pad.

[0060] The support members 103 of the present invention support the shelter 100 along the top of each set of vertical protective steel plates 101, thereby enhancing the overall structural stability of the shelter 100 and making it more resistant to external impact or pressure, such as explosions, earthquakes and other extreme situations.

[0061] In some embodiments, the support member 103 is a group of support plates extending from the bottom of each group of vertical protective steel plates 101 toward the second gap 6. Further, each group of support plates includes at least two horizontal steel plates arranged at intervals. A plurality of gravel holes of different sizes are provided on a horizontal bar plate above a group of support plates arranged at the bottom of the vertical protective steel plates 101, so that the gravel collapsed from the shelter 100 can fall to the bottom of the second gap 6, which is convenient for timely cleaning of the gravel later.

[0062] Continue to see Figures 1 to 4The buffer device 2 includes a fan 201 (suction fan), which is installed in the second gap 6 along at least one side end of each set of vertical protective steel plates 101. The fan 201 blows air directly into the second gap 6, which is suitable for applying lateral wind force to the rubble collapsed from the shelter 100. The buffer device 2 of the present invention, as a primary protection, first reduces the frontal impact force of the rubble collapsed from the shelter 100 on the anti-fall steel plate frame 1.

[0063] It is easy to understand that one side end of the vertical protective steel plate 101 refers to the end along the length direction of the shielding portion 100 .

[0064] In some embodiments, two groups of fans 201 are provided, each group of fans 201 is symmetrically arranged along the two side ends of each group of vertical protective steel plates 101, and one group of fans 201 is installed on the top side of each group of vertical protective steel plates 101 along the second gap 6, and the other group of fans 201 is installed on the bottom side of each group of vertical protective steel plates 101 along the second gap 6.

[0065] It is easy to understand that the present invention installs a group of fans 201 along the top side of each group of vertical protective steel plates 101 in view of the fact that shear failure is prone to occur on the upper part of the shelter 100. A group of fans 201 are installed along the top side of the outer side of each group of vertical protective steel plates 101 to apply lateral wind force to the crushed stones collapsed from the upper part of the shelter 100, thereby reducing the frontal impact force of the crushed stones on the top of the anti-fall steel plate frame 1.

[0066] The present invention installs a group of fans 201 along the bottom side of each group of vertical protective steel plates 101. In addition to applying lateral wind force to the collapsed gravel in the sheltering part 100 to reduce the frontal impact force of the gravel on the anti-falling steel plate frame 1, the gravel falling into the second gap 6 can also be blown from both sides to the middle, which is convenient for later cleaning.

[0067] In some embodiments, see Figure 3 , Figure 4 The buffer device 2 further includes a transverse transport channel 202. The transverse transport channel 202 is arranged at the bottom of the outer sides of the two sets of vertical protective steel plates 101 along the length direction of the shielding portion 100. The top of the transverse transport channel 202 is open, and fans 201 are arranged at both side ends.

[0068] Furthermore, the buffer device 2 also includes a vertical transport channel 203. The vertical transport channel 203 is arranged in the middle of the outer sides of the two sets of vertical protective steel plates 101 along the height direction of the shielding portion 100, the vertical transport channel 203 is connected with the horizontal transport channel 202, and a suction machine 204 (suction fan) is arranged at the top of the vertical transport channel 203.

[0069] Specifically, when the fans 201 on both sides of the horizontal transport channel 202 blow against each other, the gravel on both sides of the second gap 6 is blown to the bottom of the vertical transport channel 203. Since the airflows blowing against each other are mutually restricted at the bottom of the vertical transport channel 203, the bottom gravel is transported to the movable steel plate at the top under the action of the suction machine 204 at the top of the vertical transport channel 203, so that the gravel can be transported to the outside of the shelter 100 through the movable steel plate to prevent blockage that causes the entire device to fail to function.

[0070] In some embodiments, the transverse transport channel 202 can also be set on the top of the outer side of the two groups of vertical protective steel plates 101 along the length direction of the sheltering portion 100. The transverse transport channel 202 set along the top is open to one side of the sheltering portion 100, so that the rubble collapsed from the upper part of the sheltering portion 100 can be transported to the movable steel plate on the top through the transverse transport channel 202 and the vertical transport channel 203 in time, thereby reducing the transport pressure at the bottom of the vertical transport channel 203.

[0071] In the present invention, the transverse transport channel 202 arranged at the outer bottom of the two groups of vertical protective steel plates 101 along the length direction of the shielding portion 100 and / or arranged at the outer top of the two groups of vertical protective steel plates 101 along the length direction of the shielding portion 100 can be used as the support member 103.

[0072] See also Figure 1 , Figure 2 The energy dissipation device 3 is provided with a plurality of energy dissipation devices 3, and the plurality of energy dissipation devices 3 are evenly installed in the first gap 5 of each set of vertical protective steel plates 101 along the length direction of the shelter 100. The energy dissipation device 3 of the present invention serves as a secondary protection to further consume the residual impact energy of the rubble collapsed from the shelter 100 on the anti-fall steel plate frame.

[0073] In some embodiments, see Figure 5 The energy dissipation device 3 includes an energy dissipation block 301 , prestressed tendons 302 , grouting concrete 303 and a buffer column 304 .

[0074] The energy dissipation block 301 is a rectangular solid block, which is installed in the first gap 5 between the double-layer steel plates of the vertical protective steel plate 101, and the outer surface of the block is in close contact with the inner surface of the vertical protective steel plate 101. The energy dissipation block 301 is provided with a plurality of prestressed holes along its length direction, which are suitable for placing the prestressed tendons 302 and stretching them, and then pouring the grouting concrete 303 in the prestressed holes, and finally installing nuts 305 at both ends of the prestressed tendons 302 to fix them. The prestressed tendons 302 and the grouting concrete 303 of the present invention play a role in preventing buckling and dissipating energy.

[0075] Furthermore, both sides of the top and bottom of the energy dissipation block 301 are extended outwardly with connecting plates 3011. The outer surface of the connecting plate 3011 is in close contact with the inner surface of the vertical protective steel plate 101. The connecting plate 3011 is provided with connecting holes 3012, and the vertical protective steel plate 101 and the connecting plate 3011 are provided with the same holes at the corresponding positions where they are in close contact. The buffer column 304 passes through the connecting hole of the connecting plate 3011 and the hole of the vertical protective steel plate 101, and its two ends are fixed by nuts 305. The buffer column 304 of the present invention can play a good role in buffering and dissipating energy.

[0076] In some embodiments, see Figure 6 The buffer column 304 includes a buffer column body 3041, an inner slot 3042 and an inner rotating column 3043. The buffer column body 3041 is a columnar solid body, which is used to penetrate the holes of the energy dissipation block 301 and the vertical protective steel plate 101. The inner slot 3042 is through-opened in the buffer column body 3041, and a plurality of clamping parts (not shown in the figure) are radially arranged on the outer periphery of the inner slot 3042. The inner rotating column 3043 is arranged in the inner slot 3042, and an inner clamping device is arranged on the inner rotating column 3043, which is suitable for abutting against the surface of the inner slot 3042 when the inner rotating column 3043 is in a normal state, and is clamped to the clamping part after the inner rotating column 3043 is rotated under force.

[0077] In a specific embodiment, the engaging portion is a groove whose surface of the inner slot 3042 is recessed inwardly.

[0078] In a specific embodiment, the inner clamping device includes a plurality of telescopic ejection clamping heads, which are arranged around the outer circumference of the inner rotating column 3043 along the length direction thereof. The tails of the plurality of telescopic ejection clamping heads are installed on the inner rotating column 3043, and the heads are compressed and abutted against the surface of the inner clamping groove 3042 in the normal state of the inner rotating column 3043, and are ejected and clamped to the clamping portion after the inner rotating column 3043 is rotated under force. It is easy to understand that the specific structure of the clamping portion and the inner clamping device includes but is not limited to the above structure, and can also be other structures that can realize the above clamping function.

[0079] The energy consumption principle of the energy consumption device 3 of the present invention is:

[0080] When the fallen rocks from the sheltering part 100 hit the anti-falling steel plate frame 1, the impact force will be transmitted to the energy absorbing block 301 of the energy absorbing device. The prestressed energy absorbing block 301 will first consume part of the energy. At the same time, the inner rotating column 3043 of the energy absorbing device 3 will rotate, and at the same time, the inner clamping device will be driven to rotate. Since the inner clamping device can be extended and retracted, and can only be extended and retracted vertically, it will directly pop out and be connected to the clamping part after rotation, thereby further consuming the impact energy of the rocks on the anti-falling steel plate frame 1.

[0081] In some embodiments, see Figure 5, a clamping block 306 is provided at the bottom of the energy dissipation block 301, and a clamping plate is provided at the bottom of the vertical protective steel plate 101 along the first gap 5, and a clamping groove is provided on the clamping plate, and the clamping groove is adapted to the clamping block 306, and is suitable for clamping and fixing the clamping block 306. The present invention uses the clamping block 306 to clamp and fix with the vertical protective steel plate 101, and the clamping and fixing method ensures that the energy dissipation block 301 can remain stable when impacted, and will not fall off or shift, thereby improving the overall safety of the protective device.

[0082] In some embodiments, see Figure 1 , the anti-fall protection device also includes a gravel splashing net 4. The gravel splashing net 4 is installed between the anti-falling steel plate frame 1 and the shelter 100 along the two side ends of the anti-falling steel plate frame 1. The purpose of setting the gravel splashing net 4 in the present invention is to prevent the gravel that falls on the top of the anti-falling steel plate frame 1 and the gravel that is transported to the top of the anti-falling steel plate frame 1 through the transport channel from splashing outside the shelter, causing unnecessary personal injury. In addition, by preventing the gravel from splashing outside the shelter 100, the gravel splashing net 4 reduces the pollution and damage of the external environment, thereby reducing the maintenance cost of the external structure of the shelter 100 and the surrounding environment.

[0083] The present invention utilizes a buffer device and a plurality of energy dissipation devices to provide multi-level protection for the anti-falling steel plate frame. This multi-level protection mechanism can significantly improve the impact resistance of the anti-falling steel plate frame and more effectively prevent the debris that collapses inside the shelter from causing harm to the personnel inside.

[0084] It is easy to understand that the design of the anti-fall protection device for the interior of the deep-sea island and reef shelter proposed by the present invention is flexible and scalable, and one or more such protection devices can be installed on the inner side of the shelter according to the specific size of the shelter and the protection requirements. For a shelter with a shorter depth dimension, only one anti-fall protection device can be set, and for a shelter with a longer depth dimension, multiple anti-fall protection devices can be installed. There may be some structural weaknesses on the inside of the shelter, such as wall cracks, weak areas, etc. Installing anti-fall protection devices at these locations can enhance the overall stability of the structure and prevent overall collapse due to local damage.

[0085] In addition, multiple protection devices can be connected to each other through connectors or supporting structures to form an integrated protection system, which can not only improve the protection effect, but also enhance the overall stability of the structure.

[0086] The present invention also provides a method for installing the above-mentioned anti-fall protection device, comprising the following steps:

[0087] S10: prefabricate two sets of vertical protective steel plates 101 and one set of horizontal protective steel plates 102 of the anti-fall steel plate frame 1 according to the internal dimensions of the deep-sea island reef shelter;

[0088] S20: Prefabricated in the factory Figure 5 The multiple energy dissipation devices 3 shown are all made of steel. Specifically, the prestressed tendons 302 are passed through the prestressed holes reserved in the energy dissipation block 301 to pre-tension the prestressed tendons 302.
