Description

Technical Field

[0001] The invention belongs to the technical field of impact protection, in particular to an energy absorbing and buffering impact protection structure suitable for disasters caused by impact objects such as falling rocks. Background Art

[0002] In the case of impact-proof structures, especially impact-proof nets, when they are affected by the external environment, such as sunlight, alternating hot and cold, the material of the impact-proof net will age faster, its life will be shortened, and its performance will decrease. In some areas, the impact-proof net may hinder the migration routes of wild animals. The impact-proof net is damaged by external forces and produces sharp corners, which will cause harm to wild animals nearby. When the impact objects such as falling rocks are too large, the impact-proof net will be damaged due to the high local force. The impact objects that break through the impact-proof net will not only pose a great threat to people's safety, but also damage the protected objects. In summary, the impact-proof net will fail due to material aging in the natural environment, affecting the normal activities of nearby wild animals. When the impact-proof net is unevenly stressed, it will be damaged. Using this portable long-term energy-absorbing buffer structure that resists impact, it can maintain normal working conditions for a long time, with little impact on wild animals. Impact objects such as falling rocks are blocked in front of the baffle to prevent the impact objects from hitting the protected objects. Summary of the invention

[0003] Aiming at the shortcomings of the existing anti-impact net structure, a portable long-term energy-absorbing and buffering structure that can resist impact is invented.

[0004] The present invention adopts the following technical solution:

[0005] A portable long-acting energy-absorbing and buffering structure for resisting impacts comprises: a baffle (1), an energy-absorbing part, a transmission structure (6), an inner layer structure (7), and an outer layer structure (8); the energy-absorbing part comprises a spring (2), a shear thickening liquid (3), foamed aluminum (4), and a surrounding ring (5); the transmission structure (6) comprises a truncated cone (601), a connecting shaft (602), a fastener (603), and a piston (604); the inner layer structure (7) comprises an inner layer shell wall (701), a piston buckle (702), and a thick liquid channel (703); the outer layer structure (8) comprises an outer layer shell wall (801), a bottom plate (802), and a ring buckle (803); the structure is assembled from the inside out in the order of the transmission structure (6), the inner layer structure (7), and the outer layer structure (8).

[0006] Furthermore, the connection point between the connecting shaft (602) and the baffle (1) is a truncated cone (601), and the contact area between the truncated cone (601) and the baffle (1) is large, thereby providing greater stability.

[0007] Furthermore, a spring (2) is provided in the energy absorbing part, and its two ends are respectively connected to the fastener (603) and the top of the inner shell wall (701), and a total of four springs are provided, which have the energy absorbing effect and the function of resetting the piston (604).

[0008] Furthermore, when an impact object such as a falling rock collides with the piston (604), the piston (604) moves downward, and the piston buckle (702) can stop the piston (604) from falling, thereby preventing the spring (2) from failing due to excessive stretching.

[0009] Furthermore, the energy absorbing part is provided with a shear thickening liquid (3), and when the impact object collides, the piston (604) moves downward, squeezing the shear thickening liquid (3) to flow toward the outer shell wall (801) through the thick liquid channel (703). During the flow of the shear thickening liquid (3), part of the impact force is lost in the friction between the thick liquids.

[0010] Furthermore, the energy absorbing part is provided with a surrounding ring (5) and foamed aluminum (4). Under the extrusion of the shear thickening fluid (3), the surrounding ring (5) is driven to move upward and the foamed aluminum (4) is extruded. The deformation of the foamed aluminum (4) can absorb part of the impact force.

[0011] Furthermore, after the device is operated, the circular buckle (803) can fall around the circular ring (5), leaving a space between the thick liquid channel (703) and the circular ring (5), thereby ensuring that the shear thickening liquid (3) can flow to the outer layer during the next operation.

[0012] The present invention has the following advantages:

[0013] (1) Due to the airtightness of the structure, the interaction between the internal structure and materials and the outside world is reduced to a low level, and the influence of the outside world is small, thus ensuring its working condition.

[0014] (2) The angle of the structure can be adjusted and it can be placed vertically, horizontally or laterally as needed on wildlife migration routes without interfering with the normal activities of wildlife.

[0015] (3) Under the combined action of the baffle and the energy-absorbing part, falling rocks and other impact objects are blocked in front of the baffle and will not hit the protected object. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only 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 the present application.

[0023] The embodiment of the present invention provides an anti-impact structure suitable for impact disasters, which is used to solve the shortcomings of existing anti-impact nets in resisting impact objects such as falling rocks. The anti-impact nets are affected by the external environment, resulting in material aging and reduced efficiency. When arranged in nature, they will hinder the migration routes of wild animals. The protective nets cannot effectively block impact objects such as falling rocks, and the impact objects will continue to move.

[0024] In order to clearly express the purpose, technical solutions and advantages of the present invention, the specific implementation steps of the present invention are further described below in conjunction with the accompanying drawings.

[0025] A portable long-acting energy-absorbing and buffering structure for resisting impact comprises the following steps:

[0026] Assembly of the structure:

[0027] First, insert the connecting shaft (602) through the middle hole of the inner shell wall (801), then push the piston (604) in from the bottom of the inner shell wall (801), and then push the piston buckle (702) in from the bottom.

[0028] , then connect the spring (2) to the fastener (603) and the inner shell wall (801). Push the assembled shaft (602) and inner structure (7) from below the outer shell wall (8) through the hole of the outer shell wall (8).

[0029] , fill the foam aluminum (4) into the gap between the inner shell wall (7) and the outer shell wall (8), then push the surrounding ring (5) in, and then push the ring buckle (803) in to fix it.

[0030] , the shear thickening liquid (3) is filled into the space formed by the surrounding ring (5), the bottom plate (802), the piston (604), the inner shell wall (701), and the thick liquid channel (703), and finally the bottom plate (802) is connected.

[0031] Finally, the baffle (1) is connected to the round table (601), and the round table (601) is connected to the connecting shaft (602). At this point, the overall structure is installed.

[0032] Installation and use of the structure:

[0033] , Use in human activity areas:

[0034] The energy-absorbing buffer structure is installed in a horizontal, oblique, or inverted manner according to the impact direction of the impact object and the position of the protected object. The baffle (1) is installed so that it is inclined in the impact direction of the impact object such as falling rocks. When the impact object such as falling rocks rolls down and hits the structure, the energy-absorbing part of the structure starts to work. After the energy-absorbing action of the spring (2), the shear thickening liquid (3), and the foam aluminum (4), the impact force is partially absorbed. When the impact force exceeds the bearing capacity of the structure, the impact object is rebounded to the original impact direction to prevent the impact object from directly hitting the protected object. It can also be placed in a notch manner, so that one side of the baffle (1) is close to the slope and the other side is away from the slope. When the impact object continues to move after hitting the baffle (1), the impact object will roll out from the notch direction and away from the protected object.

[0035] , Use within the range of wild animal activities:

[0036] When buildings or roads are close to animal habitats, the structure for resisting impact disasters may be installed on the path of wildlife activities. The angle and direction of the baffle (1) and the structure can be adjusted according to the migration route or activity path of local wildlife, so that the wildlife can cross over or bypass the structure.

[0037] , combined use:

[0038] The structure is compact and easy to install. Therefore, when the impact objects such as falling rocks are large and in large numbers, multiple structures can be installed in the area to work together. There are two specific situations: multiple structures are installed independently, and the angle of the baffle (1) of each structure is set according to the rolling direction of the impact object, so that the baffle (1) is directly facing or obliquely facing the rolling direction of the impact object. When the number of impact objects is large, each impact object is blocked separately to ensure the safety of the protected object; multiple structures are installed together and share a baffle (1). When the impact object is too large, multiple structures work simultaneously and work together to block the impact of large-volume impact objects.

[0039] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or structure including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or structure. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or structure including the elements.

[0040] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
