Description

Technical Field

[0001] This invention relates to the field of protective equipment technology, specifically to a flat, overlapping, mortise-and-tenon modular honeycomb interception net and system. Background Technology

[0002] With the rapid popularization of drone technology and the continuous expansion of its application scenarios, the aerial threats posed by malicious drone intrusions are becoming increasingly prominent, posing a severe challenge to the security of fixed facilities such as airports, military bases, energy hubs, and large venues. These aerial threats are characterized by strong concealment, high mobility, and wide attack range. Traditional active interception methods (such as radar monitoring and electronic jamming) are easily affected by complex environments and have blind spots and the risk of false interceptions. Therefore, deploying large-area physical interception networks as a passive protection measure, with its advantages of being direct, reliable, and unaffected by electromagnetic interference, has become an important component of the aerial protection system for fixed facilities.

[0003] Traditional physical interception nets used for aerial threat protection mostly employ an integral woven or welded structure design. While these nets can form a continuous protective surface and possess a certain interception strength, their integral configuration has many inherent drawbacks, severely limiting their practical application effectiveness and promotional value. On the one hand, integral interception nets are bulky and heavy, causing great inconvenience in transportation, especially for special installation scenarios such as mountainous areas and high altitudes, resulting in high transportation costs and difficulties. On the other hand, their installation process is cumbersome and inefficient, requiring the use of large hoisting equipment and multiple workers, leading to low installation efficiency and high requirements for the flatness and load-bearing capacity of the installation site. More importantly, when such nets are partially damaged (such as broken braids or detached welds), targeted local repairs and replacements are not possible; the entire net must be scrapped and replaced. This not only significantly increases subsequent maintenance costs but also leads to prolonged interruptions in the protection system, leaving safety hazards.

[0004] To address the aforementioned shortcomings of monolithic interception nets, the industry has gradually explored modular protection net solutions. These solutions break down the interception net into multiple modular units, aiming to optimize transportation, installation, and maintenance convenience. However, existing modular solutions still face technical bottlenecks, failing to fundamentally balance connection reliability, assembly efficiency, and structural integrity. Furthermore, they do not fully exploit the potential advantages of modular configurations in terms of mechanical performance, and their application effectiveness still falls short of meeting the high-strength aerial protection requirements of fixed facilities.

[0005] Current physical interception systems for protecting fixed facilities from aerial threats, whether traditional monolithic or modular, suffer from insurmountable technical flaws. The market urgently needs a new type of modular protection system that overcomes the inherent shortcomings of discrete point connections, achieving more robust and stable connections between modules. It also simplifies assembly processes, improves alignment efficiency and assembly speed, enables coordinated force distribution between modules, and significantly enhances the overall rigidity, stability, and impact resistance of the entire protection system to meet the practical needs of fixed facilities for efficient and reliable protection against aerial threats. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problems of insufficient overall rigidity, stability and impact resistance of the protection system in the prior art, and to provide a flat overlapping tenon and mortise modular honeycomb interception net and system.

[0007] To address the aforementioned technical problems, this invention provides a flat, overlapping, mortise-and-tenon modular honeycomb interception net, comprising multiple assembly units. Each assembly unit includes an installation frame and connectors. The installation frame includes a central frame and multiple extension plates. The central frame is configured as a hexagonal frame structure. The multiple extension plates are respectively connected to the six sides of the central frame, and adjacent extension plates are alternately arranged on both sides of the central frame in the thickness direction. Each extension plate extends from the side of the central frame in a direction away from the central frame. The connectors pass through the extension plates in adjacent assembly units to allow for detachable connection between the multiple assembly units, and the adjacent assembly units are arranged in a centrally symmetrical structure.

[0008] In one embodiment of the present invention, the thickness of the extension plate is less than the thickness of the central frame, and the two interconnected extension plates together enclose a buffer space, wherein a buffer element is provided in the buffer space.

[0009] In one embodiment of the present invention, the buffer is sleeved on the connector, and the two ends of the buffer abut against the two extension plates respectively.

[0010] In one embodiment of the present invention, the extension plate is provided with a mating hole, the connector includes a bolt and a nut that mates with the bolt, the bolt passes through the mating hole, and the nut abuts against the outer surface of the extension plate and is connected to both ends of the bolt.

[0011] In one embodiment of the present invention, the extension plate is provided with a guide tenon, which extends along the thickness direction of the central frame and can be inserted into the mating hole of the extension plate connected to it.

[0012] In one embodiment of the present invention, the flat overlapping mortise and tenon modular honeycomb interception net further includes multiple energy dissipation units, which are embedded in the connection gaps of the multiple assembly units.

[0013] In one embodiment of the present invention, the energy dissipation unit includes two energy dissipation plates and reinforcing bolts. The two energy dissipation plates are respectively interference-fitted between adjacent extension plates and connected to the extension plates. The reinforcing bolts connect and fix the two energy dissipation plates.

[0014] In one embodiment of the present invention, the assembly unit further includes a filler that fills the interior of the central frame.

[0015] In one embodiment of the present invention, the assembly unit further includes a support member located inside the central frame and abutting against the inner wall of the central frame, and the filler member is connected to the support member.

[0016] The present invention also provides a flat overlapping mortise and tenon modular honeycomb interception system, which includes the above-mentioned flat overlapping mortise and tenon modular honeycomb interception net.

[0017] The technical solution of the present invention has the following advantages compared with the prior art: The flat, overlapping, mortise-and-tenon modular honeycomb interception net and system described in this invention effectively solves the technical defects of traditional interception nets and existing modular solutions, such as inconvenient transportation and installation, insufficient connection strength, low assembly efficiency, poor overall stability, and high maintenance costs, through innovative design of the structural form, connection method, and layout logic of the assembly unit.

[0018] The mounting frame of the assembly unit adopts a hexagonal central frame structure, with extension plates on both sides of the thickness direction alternately arranged on the six sides. When adjacent assembly units are spliced, the extension plates can form a flat and overlapping connection interface. With the help of connectors, they are fixed in place, forming an integrated mortise and tenon joint connection structure. Compared with the traditional discrete point connection structure, this design significantly increases the load-bearing contact area through the flat and overlapping interface. Combined with the fastening effect of the connectors, it forms a strong mechanical interlocking force, making the strength of the connection part close to the frame material itself. The connection reliability is far superior to point connection methods such as bolts and clamps. On the other hand, it can build a continuous force transmission path. When the interception net is subjected to external loads such as drone impacts and wind, the impact energy can be quickly and evenly diffused to adjacent assembly units through the overlapping interface and hexagonal frame, completely avoiding the loosening and breakage failure problems caused by stress concentration at local connection points, and significantly improving the impact resistance and structural durability of the interception net.

[0019] Meanwhile, the adjacent assembly units are arranged in a centrally symmetrical structure, and the design of alternating extension plates allows the extension plates to naturally achieve self-centering positioning during assembly, forming a natural guiding tenon-and-mortise fit relationship. Precise fitting between modules can be achieved without relying on high-precision alignment tools. Fixing can be completed simply by inserting overlapping extension plates through connectors. The operation process is simple and convenient, greatly shortening the construction cycle, reducing construction difficulty and labor and equipment costs, and making it suitable for more complex installation scenarios.

[0020] The honeycomb macrostructure constructed from hexagonal central frame units leverages the inherent high geometric invariance and in-plane stiffness of the hexagon, along with the symmetrical arrangement of adjacent units, to create a unified, force-coordinated interception network rather than a simple stacking of independent modules. This effectively disperses external loads from multiple directions. Whether it's a frontal or oblique impact from a drone, or lateral loads caused by wind, these can be quickly transmitted and dissipated through the overall structure, preventing localized deformation, swaying, or module separation. Compared to existing modular solutions, this represents a qualitative improvement in overall stability, maintaining the flatness and integrity of the protective surface for a long time and ensuring continuous and reliable protection.

[0021] Furthermore, adjacent assembly units are detachably connected via connectors, and each unit is independent and complete. When a part of the interception net is damaged, there is no need to dismantle and replace the entire net. Only the connectors on the extension plate of the corresponding damaged unit need to be disconnected, allowing for quick disassembly and replacement of one or a few assembly units. This makes maintenance operations convenient and efficient, significantly reducing protection downtime, maintenance costs, and resource waste. Moreover, the assembly units adopt a standardized hexagonal structure and uniform connection specifications, allowing for flexible increases or decreases in the number of assembly units based on the shape and size of the protected area. Through a centrally symmetrical layout logic, it is possible to assemble and splice protective surfaces of any area and shape, adapting to the protection needs of different fixed facilities such as airports, military bases, and energy hubs. Its scalability far exceeds that of traditional integrated interception nets and modular solutions with fixed specifications.

[0022] In summary, this invention achieves multiple technical advantages through structural innovation, including robust connection, efficient assembly, overall stability, convenient maintenance, and wide adaptability. It can provide a more reliable and efficient aerial threat protection solution for fixed facilities, and has extremely high industrial application value and promotion prospects.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0027] Example 1: See Figures 1 to 3 As shown, this embodiment provides a flat, overlapping, mortise-and-tenon modular honeycomb interception net, which includes multiple assembly units 100. Each assembly unit 100 includes a mounting frame 110 and a connector 120. The mounting frame 110 includes a central frame 111 and multiple extension plates 112. The central frame 111 is configured as a hexagonal frame structure. The multiple extension plates 112 are respectively connected to the six sides of the central frame 111, and two adjacent extension plates 112 are alternately arranged on both sides of the central frame 111 in the thickness direction. Each extension plate 112 extends from the side of the central frame 111 in a direction away from the central frame 111. The connector 120 passes through the extension plates 112 in adjacent assembly units 100 to allow the multiple assembly units 100 to be detachably connected, and the adjacent assembly units 100 are arranged in a centrally symmetrical structure.

[0028] In this embodiment, the assembly unit 100 serves as the core component of the interception net, undertaking the fundamental functions of constructing the protective surface, transferring loads, and realizing modular splicing. Each assembly unit 100 is structurally independent and complete, allowing for individual production, transportation, and storage. Compared to traditional integrated interception nets, this significantly reduces space occupancy and weight load during transportation, facilitating handling in complex environments such as mountainous areas and high altitudes. It also provides a structural basis for subsequent partial repairs and replacements, and flexible expansion of the protective area.

[0029] The adjacent assembly units 100 are arranged in a centrally symmetrical structure. On the one hand, this ensures that the extension plates 112 of adjacent units can accurately correspond and fit together, ensuring the flatness and overlap of the connection interface and avoiding excessive gaps due to layout deviations, which would affect force transmission and structural rigidity. On the other hand, the centrally symmetrical layout makes the force distribution of the entire interception net more balanced. When subjected to local impact loads, the impact force can be quickly diffused to the surrounding areas through the centrally symmetrical unit structure, avoiding local stress concentration. At the same time, this layout allows the hexagonal units to form a regular honeycomb structure, maximizing the deformation resistance and impact resistance advantages of the honeycomb structure, and improving the overall stability and protective effect of the interception net.

[0030] The mounting frame 110, serving as the main load-bearing structure of the assembly unit 100, is divided into a central frame 111 and an extension plate 112, which work together to achieve load-bearing, positioning, and connection functions. Specifically, the central frame 111 is configured as a hexagonal frame structure, which gives it excellent geometric invariance and in-plane stiffness. Compared to circular or rectangular structures, it provides higher resistance to deformation with the same amount of material, effectively resisting multi-directional external loads such as drone impacts and wind, and preventing localized deformation from causing protection failure. Furthermore, the hexagonal shape is an equilateral structure, with each side serving as a connecting edge to adjacent assembly units 100. It can also naturally form a honeycomb-like macrostructure through splicing, ensuring even distribution of force across the entire interception net and improving overall structural stability. In addition, the hexagonal frame structure is compact, allowing for reasonable weight control while ensuring load-bearing strength, balancing structural strength and lightweight requirements, and facilitating assembly.

[0031] In this embodiment, the multiple extension plates 112 serve as connecting extension structures for the mounting frame 110, and their design and arrangement directly determine the connection reliability and assembly convenience. The extension plates 112 are respectively connected to the six sides of the central frame 111, with adjacent extension plates 112 alternately arranged on both sides of the central frame 111 in the thickness direction, extending from the sides of the central frame 111 away from it. This alternating arrangement allows the extension plates 112 of one unit to mutually abut with the corresponding extension plates 112 of another unit in the thickness direction when adjacent assembly units 100 are connected, forming a flat and overlapping connection interface, rather than discrete contact. This significantly increases the connection bearing area, providing structural support for the subsequent fixing of the connectors 120 and the uniform transmission of force. Simultaneously, the extension length and alternating arrangement angle of the extension plates 112 are precisely designed to form a natural guiding and positioning structure, enabling rapid alignment of adjacent units without the need for additional alignment tools during assembly. In addition, the extension plate 112 serves as the mounting carrier for the connector 120. By reserving mounting holes for the connector 120 to pass through, the connection force can be evenly transmitted to the central frame 111 through the extension plate 112, avoiding stress concentration at the connection point. At the same time, the structural strength of the extension plate 112 can match that of the central frame 111, ensuring that the strength of the connection part is consistent with the main structure and improving the overall load-bearing capacity.

[0032] Furthermore, in this embodiment, the thickness of the extension plate 112 is less than the thickness of the central frame 111. The two interconnected extension plates 112 together enclose a buffer space, in which a buffer element 130 is provided. This dimensional design allows the two interconnected extension plates 112, after being fitted and fixed, to enclose a specific buffer space between the central frames 111 of two adjacent assembly units 100. This buffer space provides a suitable structural carrier for the installation of the buffer element 130, and the buffer element 130 installed within the buffer space can fully exert its energy absorption and shock absorption function. When the interception net is subjected to external impact loads such as drone impacts, the buffer element 130 can absorb and dissipate some of the impact energy first, preventing the impact force from directly acting on the central frame 111 and the connecting parts. The buffer 130 effectively reduces the deformation risk of the central frame 111 and the stress load at the connection point of the extension plate 112. At the same time, the elastic deformation characteristics of the buffer 130 can further optimize the load transmission path, allowing the impact force to spread more smoothly to the entire interception net structure. Combined with the hexagonal honeycomb configuration of the central frame 111 and the flat overlapping connection of the extension plate 112, the impact resistance and structural durability of the interception net are greatly improved. In addition, the reserved buffer space also allows the buffer 130 to be easily disassembled and replaced, further enhancing the convenience of later maintenance of the interception net.

[0033] Specifically, in this embodiment, the buffer 130 is sleeved on the connector 120, and both ends of the buffer 130 abut against the two extension plates 112 respectively. This assembly structure not only achieves precise positioning of the buffer 130 with the help of the connector 120, preventing the buffer 130 from shifting or falling off within the buffer space and ensuring that it is always on the critical path of force transmission, but also enables the buffer 130 to apply a reverse buffering force to the two extension plates 112 simultaneously through its own elastic deformation when the interception net is subjected to external impact loads. This efficiently absorbs and dissipates the impact energy, significantly weakens the impact force transmitted to the connection parts of the extension plates 112 and the central frame 111, and further reduces the risk of stress concentration at the connection points. At the same time, the sleeved cooperation between the buffer 130 and the connector 120 can integrate the buffering function and the connection function without adding extra installation space and operation steps, simplifying the overall assembly process and improving the structural compactness and practicality of the interception net.

[0034] In this embodiment, the buffer 130 is preferably a disc spring. In different implementations, the buffer 130 can also be configured as an elastic structure such as elastic rubber or polymer damping pad according to actual usage requirements. This application does not impose any specific restrictions on it.

[0035] See Figure 3 As shown, in this embodiment, the connector 120 serves as a fixing component between the assembly units 100. Its core function is to achieve detachable connection of multiple assembly units 100 while ensuring connection strength and stability. The connector 120 passes through the overlapping extension plates 112 of adjacent assembly units 100, firmly combining the dispersed assembly units 100 into a whole. Its detachable characteristic enables the interception net to have convenient maintenance and expansion capabilities. When a local unit is damaged, the damaged unit can be quickly replaced by disassembling the corresponding connector 120 without dismantling the entire unit. At the same time, the fastening effect of the connector 120 can enhance the fit between the extension plates 112, forming a tight mechanical interlocking relationship between the flat and overlapping interfaces. This effectively resists the separation force brought by external loads, preventing loosening or displacement between the assembly units 100, and ensuring the integrity and reliability of the entire interception net structure. Compared with discrete connections such as bolts and clamps, the connection method of the connector 120 in conjunction with the extension plates 112 makes the force transmission more continuous and uniform, further improving connection stability.

[0036] In this embodiment, the connector 120 includes a bolt 121 and a nut 122 that mates with the bolt 121. The bolt 121 passes through a mating hole 1121 on the extension plate 112, and the nut 122 abuts against the outer surface of the extension plate 112 and is connected to both ends of the bolt 121. This structural design, through the threaded fastening action of the bolt 121 and the nut 122, can tightly press the extension plates 112 of adjacent assembly units 100 together, ensuring that the flat and overlapping connection interfaces fit tightly, forming a reliable mechanical interlocking structure, and effectively improving the connection strength. At the same time, the detachable connection of the bolt 121 and nut 122 facilitates the disassembly and replacement of damaged assembly units 100 in the future, greatly reducing the difficulty of maintenance operations. In addition, the assembly method of the bolt 121 passing through the mating hole 1121 can accurately define the relative position of adjacent extension plates 112, avoiding misalignment during assembly, and further ensuring the connection accuracy and the stability of the overall structure.

[0037] Furthermore, in this embodiment, the extension plate 112 is provided with a guide tenon 1122, which extends along the thickness direction of the central frame 111 and can be inserted into the mating hole 1121 of the extension plate 112 connected to it. This design enables the extension plate 112 to have a precise self-guiding positioning function. During the assembly of adjacent assembly units 100, the guide tenon 1122 can be inserted into the mating hole 1121 of the corresponding extension plate 112 first, quickly calibrating the relative position of the two extension plates 112, avoiding offset deviations during manual alignment, and greatly improving assembly efficiency and connection accuracy. At the same time, the fitting of the guide tenon 1122 and the mating hole 1121 can pre-form a preliminary mechanical limit before the bolts 121 and nuts 122 are tightened, preventing the assembly unit 100 from shaking or shifting during assembly, providing a stable operating basis for the subsequent installation of the connector 120. The extension structure of the guide tenon 1122 along the thickness direction can further enhance the tightness of the fit between the extension plates 112. Combined with the tightening force of the bolts 121 and nuts 122, the connection interface forms a double-reinforced structure, significantly improving the shear resistance and overall rigidity of the connection part, effectively dispersing impact loads, and preventing the connection point from becoming a weak link with stress concentration.

[0038] In different embodiments, a guide groove can also be provided on the extension plate 112. The guide tenon 1122 can be configured as a T-shaped, dovetail-shaped strip or other structure according to actual usage requirements to cooperate with its corresponding guide groove. This application does not impose specific restrictions on this.

[0039] In this embodiment, the flat, overlapping, mortise-and-tenon modular honeycomb interception net also includes multiple energy dissipation units 200, which are embedded in the connection gaps of the multiple assembly units 100. This design can make full use of the gap space formed after the assembly units 100 are spliced ​​together, thereby further enhancing the protective function, without additionally occupying the effective protective area of ​​the interception net. When the interception net is struck at high speed by a drone, the resulting impact load will first act on the surface of the interception net and then be transmitted to the connection gaps of each assembly unit 100. At this time, the energy dissipation unit 200 embedded therein can quickly absorb and dissipate a large amount of impact energy through its own elastic deformation or plastic deformation, which will significantly reduce the load intensity transmitted to the main body of the assembly unit 100 and the connecting structure, prevent the connection parts from loosening or breaking due to overload, and reduce the deformation damage of the central frame 111, further improving the impact resistance and structural durability of the interception net. In addition, the assembly method of embedding the energy dissipation unit 200 in the connection gap makes it easy to disassemble and replace. When the energy dissipation unit 200 reaches its energy absorption limit, it can be disassembled and replaced individually without modifying the main body of the assembly unit 100, effectively reducing the later maintenance cost and ensuring the continuous protection capability of the interception net.

[0040] Furthermore, the energy dissipation unit 200 in this embodiment includes two energy dissipation plates 210 and reinforcing bolts 220. The two energy dissipation plates 210 are respectively interference-fitted between adjacent extension plates 112 and connected to the extension plates 112. The reinforcing bolts 220 connect and fix the two energy dissipation plates 210. The interference fit assembly method forms a tight fit between the energy dissipation plates 210 and the extension plates 112. On the one hand, it can fill the assembly gap between adjacent extension plates 112, improve the sealing and structural compactness of the connection interface, and prevent external debris from entering the gap and affecting the connection stability. The sidewalls of the energy dissipation plates 210 can also be fixed to the extension plates 112 through the connectors 120. On the other hand, when the interception net is subjected to impact load, the friction force generated by the interference fit can first share part of the load. Combined with the material properties of the energy dissipation plates 210 themselves, it absorbs a large amount of impact energy, significantly reducing the stress load transmitted to the bolt 121 connection structure. The tightening effect of the reinforcing bolts 220 not only firmly connects the two energy dissipation plates 210 into one, strengthening the overall structural strength of the energy dissipation unit 200, but also further presses the contact surface between the energy dissipation plate 210 and the extension plate 112, improving the connection reliability between the energy dissipation unit 200 and the assembly unit 100, preventing the energy dissipation plate 210 from falling off or shifting under impact, and ensuring the continuous effectiveness of the energy dissipation function.

[0041] In this embodiment, the assembly unit 100 further includes a filler, which fills the interior of the central frame 111. On the one hand, the filler can form a co-load-bearing structure with the hexagonal central frame 111, filling the hollow area inside the central frame 111, improving the unit's in-plane stiffness and deformation resistance, and preventing the central frame 111 from bending or breaking due to excessive local stress when subjected to impact loads. At the same time, it can optimize the load transmission path, so that the external impact force is evenly distributed to each side of the central frame 111, further reducing the stress load on the connection part of the extension plate 112. On the other hand, the filler can be made of materials with buffering and interception properties. When the UAV breaks through the surface structure of the interception net, the filler can further dissipate the impact energy through its own extrusion deformation or toughness, slowing down the penetration speed of the UAV and improving the overall interception effect. In addition, the filler can be made of lightweight and high-strength materials, which can avoid a significant increase in the weight of the assembly unit 100 while strengthening the structural performance, ensuring the convenience of modular transportation and assembly of the interception net. At the same time, the matching filling design of the filler and the central frame 111 can reduce the impact of wind resistance on the interception net and improve the structural stability of the interception net in strong wind environments.

[0042] Specifically, the assembly unit 100 also includes a support member located inside the central frame 111 and abutting against the inner wall of the central frame 111. The filler is connected to the support member. This further enhances the load-bearing stability and structural reliability of the assembly unit 100. The close contact between the support member and the inner wall of the central frame 111 effectively disperses the local load borne by the central frame 111, preventing the hexagonal frame from experiencing localized dents or bends due to excessive stress at a single point. Simultaneously, it provides internal support stiffness to the central frame 111, improving the torsional and deformation resistance of the entire assembly unit 100 and ensuring that the central frame 111 maintains its geometric integrity under impact loads. Furthermore, the support member serves as the mounting carrier for the filler, enabling precise positioning and secure fixing of the filler inside the central frame 111. This prevents the filler from shifting, piling up, or falling off during transportation, assembly, and stress application, ensuring that the filler evenly covers the internal area of ​​the central frame 111 and fully utilizes its buffering, energy absorption, and enhanced interception functions. In addition, the support can optimize the force transmission efficiency of the filler. When an external impact is applied to the filler, the energy can be quickly transferred to the central frame 111 and the extension plate 112 connection structure through the support, realizing multi-level load dispersion. Combined with the energy absorption characteristics of the filler and the load-bearing advantages of the central frame 111, the overall protection performance of the assembly unit 100 is further improved. At the same time, the support can be designed with a hollow or lightweight structure, which can enhance the support effect while taking into account the lightweight structure, without affecting the transportation and assembly convenience of the interception net.

[0043] In different embodiments, the support member can be configured as multiple interconnected "Y"-shaped structures to abut against the joint of adjacent sides. This application does not limit the specific structure, shape and material of the support member.

[0044] In summary, the flat overlapping mortise and tenon modular honeycomb interception net described in this embodiment, through the load-bearing foundation of the central frame 111, the precise docking of the extension plate 112, the firm fixing of the connector 120, and the symmetrical arrangement of the units, jointly solves the technical defects of traditional interception nets and existing modular solutions, enabling the interception net to have the core advantages of high strength, high efficiency, high stability, and high adaptability.

[0045] Example 2: This example provides a flat overlapping mortise and tenon modular honeycomb interception system, which includes the flat overlapping mortise and tenon modular honeycomb interception net described in Example 1.

[0046] In summary, the flat overlapping mortise and tenon modular honeycomb interception net and system described in this invention effectively solves the technical defects of traditional interception nets and existing modular solutions, such as inconvenient transportation and installation, insufficient connection strength, low assembly efficiency, poor overall stability and high maintenance costs, through innovative design of the structural form, connection method and layout logic of the assembly unit 100.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
