They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0077] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0078] See Figures 1 to 5 As shown, the prefabricated UAV hub platform provided in this embodiment includes a gatepost 1, a horizontal beam 2, a platform 3, a fence 5, and a supply room 4. (See also...) Figure 5 Multiple rows of gateposts 1 are arranged in parallel, with adjacent rows of gateposts 1 connected by connecting beams 10. A horizontal beam 2 connects to two adjacent gateposts 1 in the same row to form a U-shaped frame. A platform 3 is laid on top of the horizontal beam 2, and multiple supply rooms 4 are provided on the platform 3. Optional, such as... Figure 2 As shown, multiple supply rooms 4 are arranged in multiple rows and columns; or, as... Figure 3 As shown, multiple supply rooms 4 are arranged in a row at intervals along the length of the platform 3. Each supply room 4 has at least one layer of drone parking area. A fence 5 is erected around the platform to prevent drones from sliding off the platform 3. The supply rooms 4 provide parking areas for drones, where they can be charged and repaired in preparation for their next flight. It should be noted that drones can land directly on the platform 3 or directly inside the supply room 4; this application does not specifically limit this.

[0079] Figure 1 The diagram shows a prefabricated UAV hub platform set between two buildings 200. The platform 3 is longer than the distance between the two buildings 200. The two ends of the platform 3 are supported by the buildings 200, and the middle of the platform 3 is supported by a portal frame. Figure 2 This is a schematic diagram of a prefabricated drone hub platform installed above highway 100. The highway passes through the portal frame, and platform 3 is located above highway 100, without obstructing normal traffic. The main structure of the prefabricated drone hub platform is similar in different scenarios. For ease of description, the following detailed description uses a prefabricated drone hub platform installed above highway 100 as an example.

[0080] The connecting beam 10 includes two crossbeams and a supporting beam set within the square frame formed by the two crossbeams and two rows of doorposts 1. Each crossbeam is connected at both ends to one of the two rows of doorposts 1. The supporting beam is arranged in an X-shape within the square frame, and its ends are fixedly connected to the crossbeams.

[0081] See Figures 6 to 12 Two gateposts 1 are located on one side of the highway 100, and a horizontal beam 2 spans the highway 100. The gateposts 1 located on the same side of the horizontal beam 2 are connected by truss beams 11 and diagonal bracing rods 12. The two ends of the truss beams 11 are connected to the two gateposts 1 in a one-to-one correspondence, and the diagonal bracing rods 12 are supported within the square frame formed by the two truss beams 11 and the two gateposts 1.

[0082] See Figures 6 to 12 The truss beam 11 has a first truss connection end 13 at both ends. The tail sleeve of the first truss connection end 13 is fitted onto both ends of the truss beam 11 and fixed with bolts. The first end of the first truss connection end 13 has a snap-fit ​​groove and bolt connection reinforcing plates on both sides of the snap-fit ​​groove. The snap-fit ​​groove of the first truss connection end 13 snaps onto the end protrusion extending from the door post 1 and is fixedly connected to the door post 1 by bolt connection reinforcing plates.

[0083] like Figure 9 As shown, the diagonal brace 12 includes an intermediate sleeve 121, a first connecting rod 122, and a second connecting rod 123. The intermediate sleeve 121 has a positive thread and a negative thread at both ends, respectively. The first connecting rod 122 is connected to the intermediate sleeve 121 via the negative thread, and the second connecting rod 123 is connected to the intermediate sleeve 121 via the positive thread. The ends of the first connecting rod 122 and the second connecting rod 123 away from the intermediate sleeve 121 are respectively hinged to connecting rod hinge seats 124. Specifically, both the first connecting rod 122 and the second connecting rod 123 have hinge holes, and the first connecting rod 122 and the second connecting rod 123 are hinged to the connecting rod hinge seats 124 via hinge pins. The two ends of the diagonal brace 12 are hinged to two adjacent truss beams 11 via the connecting rod hinge seats 124 and are inclined to the truss beams 11.

[0084] like Figures 6 to 12As shown, in this embodiment, the horizontal beam 2 is a cross-braced truss, which includes: an upper horizontal beam 21, a lower horizontal beam 22, vertical supports 23, and truss diagonal braces 24. The two ends of the upper horizontal beam 21 and the lower horizontal beam 22 are fixedly connected to the gatepost 1, and multiple vertical supports 23 are spaced apart between the upper horizontal beam 21 and the lower horizontal beam 22. The truss diagonal braces 24 are supported within the square frame formed by the upper horizontal beam 21, the lower horizontal beam 22, and two adjacent vertical supports 23. Specifically, the two ends of the upper horizontal beam 21 and the lower horizontal beam 22 are fixedly connected to the gatepost 1 via a second truss connecting end 25. The second truss connecting end 25 has the same structure as the first truss connecting end 13, and its specific connection method will not be described further. Multiple vertical supports 23 are evenly distributed between the upper horizontal beam 21 and the lower horizontal beam 22 and fixedly connected to the upper horizontal beam 21 and the lower horizontal beam 22 via first connecting ends. In some embodiments, refer to... Figure 6 and Figure 7 The truss diagonal brace 24 consists of four spliced ​​columns 241 arranged in an X-shape. The outer ends of the spliced ​​columns 241 are fixed to the vertical support 23, the upper beam 21, and the lower beam 22 via second connecting ends. The inner ends of the four spliced ​​columns 241 are fixed together via connecting plates 242. The second connecting ends are sleeved on the spliced ​​columns 241 and have two sets of connecting reinforcing plates, one set of which is parallel to the upper beam 21, and the other set is perpendicular to the upper beam 21. In some other embodiments, see [reference needed]. Figure 10 and Figure 11 The truss brace 24 consists of two spliced ​​columns 241 and one continuous column 243. The two spliced ​​columns 241 are positioned on opposite sides of the continuous column 243, thus forming an X-shaped structure. Designing the flat beam 2 as a lightweight cross-braced truss support structure not only helps to achieve the lightweighting of the hub platform, but also, based on the lightweighting, can form a large-span portal frame with the portal columns 1 at both ends.

[0085] In some embodiments, see Figure 6A support arch 201 is installed at the connection between the flat beam 2 and the gatepost 1. The support arch 201 includes a truss support arch beam and an outer support arch plate. At least three truss support arch beams are arranged sequentially from top to bottom, and the length of the multiple truss support arch beams decreases sequentially from top to bottom. The outer support arch plate is fixedly connected to the periphery of the multiple truss support arch beams by bolts. The multiple truss support arch beams arranged side by side provide multiple layers of protection for the gate frame during load-bearing. The tail end of the truss support arch beam is fitted with a truss connection end, and the head end of the truss connection end is provided with a snap-fit ​​groove and a second connecting reinforcement plate located on both sides of the snap-fit ​​groove. The snap-fit ​​groove of the truss connection end engages with the protruding end of the gatepost 1 and is fixedly connected to the gatepost 1 by the second connecting reinforcement plate. The outer support arch plate covers the multiple truss support arch beams and is fixedly connected by bolts to make them a whole. In some embodiments, a support rod 202 is provided at the connection between the beam 2 and the doorpost 1. One end of the support rod 202 is connected to the beam 2, and the other end is connected to the doorpost 1, to enhance the connection strength and stability of the connection between the doorpost 1 and the beam 2. See also... Figure 8 Alternatively, both the arch support 201 and the arch support rod 202 can be installed simultaneously. The specific structure of the arch support rod 202 is the same as that of the diagonal brace rod 12, and will not be described in detail here.

[0086] To improve the overall support strength of the portal frame, in some embodiments, see [reference needed]. Figure 10 and Figure 11 A vertical support arm 211 is fixedly connected to the flat beam 2. Guide wheels 212 are installed on the portal frame. The two ends of the pull cable 213 pass over the guide wheels 212 and are connected to the bottom of the portal post 1. The vertical support arm 211 and the pull cable 213 are in sliding engagement. If a support arch 201 is provided at the connection between the portal post 1 and the flat beam 2, the guide wheel 212 is installed on the support arch 201. Optionally, each support arch 201 is provided with at least one guide wheel 212. Figure 10 and Figure 11 As shown, each arch support 201 is equipped with two guide wheels 212, which are staggered horizontally and vertically. When only arch support rods 202 are installed at the connection between the gatepost 1 and the beam 2, without arch support 201, the guide wheels 212 can be installed on the gate frame via pulley supports. For example, a pulley support can be installed on the inner side of the gatepost 1 and the bottom of the beam 2, with one guide wheel 212 installed on each pulley support. The two ends of the pull-down cable 213 are connected to an electric hoist 214, which is directly fixed to the bottom of the gatepost 1 or connected to the bottom of the gatepost 1 via a foundation, etc. In some optional embodiments, see [reference needed]. Figure 10The vertical support arm 211 has an end sleeve 2110 at its end. A cable sleeve 215 is fitted onto the pull cable 213, with both ends of the cable sleeve 215 inserted and fixed within the corresponding end sleeve 2110. The pull cable 213 can move within the cable sleeve 215. A rubber post is fitted onto the pull cable 213 at the position connecting to the cable sleeve 215. The rubber post is located between the inner wall of the cable sleeve 215 and the pull cable 213 to reduce friction between them. Optionally, the pull cable 213 is a steel wire rope. It is understood that the end of the vertical support arm 211 can have only one end sleeve 2110 or multiple end sleeves 2110, the specific number matching the number of pull cables 213. For example, if two pull cables 213 are installed in parallel, then two end sleeves 2110 are installed below the vertical support arm 211. Each pull cable 213 is fitted with a cable sleeve 215, and the two cable sleeves 215 are matched one-to-one with the end sleeves 2110 below the same vertical support arm 211. (See reference) Figure 10 The vertical support arm 211 includes a support arm rod and a connecting end sleeved at the end of the support arm rod. An end sleeve 2110 is disposed at the end of the connecting end, which is fixed to the end of the support arm rod by bolts. The top of the support arm rod is fixedly connected to the flat beam 2 by bolts. In some other embodiments, see [reference needed]. Figure 11 A cable pulley 216 is installed at the bottom of the vertical support arm 211, and the pulley 213 slides in conjunction with the cable pulley 216. Specifically, the bottom of the vertical support arm 211 has a pulley mounting seat 2111, and the cable pulley 216 is mounted on the pulley mounting seat 2111 via an axle. The cable pulley 216 has a V-shaped groove, which is slidably connected to the pulley 213.

[0087] In some embodiments, such as Figure 12As shown, a lower suspension rod 217 is fixedly connected to the lower end of the vertical support arm 211, and both ends of the lower suspension rod 217 are connected to the corresponding gatepost 1. Vertical support arms 211 are distributed and connected between the horizontal beam 2 and the lower suspension rod 217. The lower suspension rod 217 is used to support the large-span horizontal beam 2, and both ends of the lower suspension rod 217 are connected to the corresponding gatepost 1. The lower suspension rod 217 includes multiple sets of tie rods 2171, each set of tie rods 2171 including at least three tie rods 2171. Multiple tie rods 2171 within the same set of tie rods 2171 are sequentially hinged together, and the multiple sets of tie rods 2171 are arranged side-by-side. A support column bracket 218 is installed at the bottom of the vertical support arm 211, and the support column bracket 218 is simultaneously connected to the multiple sets of tie rods 2171. With an arch support 201 at the connection between the gatepost 1 and the flat beam 2, the tie rod 2171 at the end is hinged to the arch support 201 on both sides of the gatepost 1. The bottom of multiple vertical connecting arms is fixed to the support column bracket 218, and the top of multiple vertical connecting arms is installed at the bottom of the flat beam 2. The bottom of the support column bracket 218 is fixed to the tie rod 2171 located at the center of the multiple tie rod 2171 groups by bolts.

[0088] In some optional embodiments, an upper tension cable 219 is provided above the flat beam 2. The upper tension cable 219 is installed in a specific space according to usage requirements, i.e., avoiding the areas where drones take off and land, to improve the seismic performance of the entire hub platform. See reference. Figure 10 An upper support arm 220 is installed above the flat beam 2. One end of the upper cable 219 is connected to the upper support arm 220, and the other end is connected to the corresponding gatepost 1. Specifically, the base of the upper support arm 220 is fixedly connected to the flat beam 2 via a support arm panel. The support arm panel is bolted to the bottom of the upper support arm 220 and the flat beam 2. An upper cable connecting seat 221 is fixedly installed on the gatepost 1 and the connecting post of the upper support arm 220. Both ends of the upper cable 219 are installed on the upper cable connecting seat 221 via hinge pin connecting seats 222.

[0089] like Figures 13 to 14 As shown, the platform 3 includes supporting beams 31 and steel grating 32. Multiple supporting beams 31 are laid parallel to each other on the bottom support frame, and the steel grating 32 is laid on the supporting beams 31. The supporting beams 31 are perpendicular to the horizontal beams 2. The steel grating 32 is fixed to the supporting beams 31, and the supply room 4 is fixed to the upper surface of the steel grating 32. The steel grating 32 has a high load-bearing capacity, with a load of more than five tons per square meter, so that the supply room 4 and other facilities can be built on the platform 3. For example, the load of the steel grating 32 per square meter can reach ten tons.

[0090] like Figures 15 to 16As shown, the supporting beam 31 includes a central square tube 311, supporting side plates 312, and supporting outer perimeter plates 313. The supporting outer perimeter plates 313 are sleeved on the outside of the central square tube 311, and the supporting side plates 312 are supported between the central square tube 311 and the supporting outer perimeter plates 313. In some embodiments, there are two supporting side plates 312, fixed to opposite sides of the central square tube 311. Each supporting side plate 312 has two oblique supporting plates that extend outward along the four corners of the central square tube 311, thereby forming an X-shaped support structure between the central square tube 311 and the supporting outer perimeter plates 313. Figure 16 As shown, the supporting side plate 312 is fixed to the central square tube 311 by bolts.

Figure 19 As shown, the protective netting 44 is installed on the open side of the supply room 4. This serves two purposes: preventing accidental entry of drones and maintaining ventilation, facilitating airflow within the supply room 4 and aiding in drone charging and heat dissipation. Optionally, the protective netting 44 can be shaped like a double door. Alternatively, both a protective door 43 and a protective netting 44 can be installed on the front side of the basic frame 41, with the protective netting 44 located inside the protective door 43.

[0093] like Figure 21 and Figure 22 As shown, the basic frame 41 includes supply room columns 411 and supply room beams 412. The two ends of the supply room beams 412 are connected to the supply room columns 411 via supply room beam-column joints 413. Column bases 414 are installed at the bottom of the supply room columns 411 to improve bottom support. The beam-column joints are fitted onto the supply room beams 412 and fixed with bolts. Specifically, the supply room beam-column joints 413 are in the shape of a tube seat, with an extension plate at one end, which is fixed to the supply room columns 411 by bolts. Figure 23 As shown, the supply room column 411 is provided with a protruding locking seat 415, and the beam-column joint has a locking clearance opening that overlaps the locking seat 415. In some embodiments, a cross-shaped support frame is provided within the square frame formed by the supply room beam 412. In some optional embodiments, such as Figure 24 As shown, the cross-shaped support frame includes one long supply room beam and two short supply room beams. The two short supply room beams are located on opposite sides of the long supply room beam and are installed on the long supply room beam via beam combination fasteners 416. Specifically, the beam combination fasteners 416 have two recessed slots 4210 and a connecting plate connecting the two recessed slots 4210. The two short supply room beams are inserted into the two recessed slots 4210 one-to-one and connected by bolts. The connecting plate is mounted on the long supply room beam and fixed by bolts.

[0094] like Figure 25 and Figure 26As shown, the composite wall panel 42 comprises multiple wall panels 421, which are modularly arranged. These panels are assembled into a complete wall panel via tie beams 422. Each wall panel 421 has a groove 4210 along its perimeter. Sealing blocks 423 are filled inside the grooves 4210. The tie beams 422 are embedded at both ends within two adjacent wall panels 421 and pass through the sealing blocks 423. Optionally, the sealing blocks 423 are made of foam. Figure 27 As shown, the wall panel 421 includes a grid layer 4211 and an intermediate filler block 4212, with the intermediate filler block 4212 sandwiched between two grid layers 4211. The grid layers 4211 on both sides and the intermediate filler block 4212 are tightened and fixed by horizontally arranged bolts, and the tie rod 422 is fixed to the inner side of the grid layer 4211. A groove 4210 is formed on the outer edge of the intermediate filler block 4212.

[0095] In some embodiments, such as Figure 28 As shown, a double-layer waterproof roof frame 45 is installed on the supply room 4. The double-layer waterproof roof frame 45 includes: an upper roof frame 451, a lower roof frame 452, and an inclined support beam 453 connecting the upper roof frame 451 and the lower roof frame 452. The upper roof frame 451 and the lower roof frame 452 are composed of multiple horizontal beams spliced ​​together. The inclined support beam 453 is H-shaped, with one end connected to the upper roof frame 451 and the other end connected to the lower roof frame 452. Composite wall panels 42 are laid on the double-layer waterproof roof frame 45. In some other embodiments, such as Figure 29 As shown, a helipad 46 is installed on the roof of the supply room 4, and a lift 47 is installed on one side of the supply room 4. The lift 47 is used to adjust the position of the drones parked on the supply room 4 and the helipad 46. In some optional embodiments, the lift 47 is elevator-shaped, and its specific structure is the same as that of a freight elevator, which will not be described in detail. In some other optional embodiments, such as Figure 30 As shown, the supply room 4 has a lift-and-avoidance passageway 471. Lifting columns 472 are installed around the lift-and-avoidance passageway 471, and a lifting platform 473 is installed on top of the lifting columns 472. A window exit 474 is provided on the lifting platform 473 corresponding to the lift-and-avoidance passageway 471. A lift 475 is installed inside the lift-and-avoidance passageway 471. The lift 475 is used to lift the drone from inside the lift-and-avoidance passageway 471 to above the window exit 474, thereby adjusting the drone's position. For example, it can be used to transport drones parked on the helipad 46 to the supply room 4 for charging, or to move fully charged drones out of the supply room 4 to make room for other drones to charge.

[0096] In this embodiment, the upper beam 21, lower beam 22, vertical support column 23, truss beam 11, supply room beam 412, and other beams used in this embodiment can adopt one or more of the following two beam structures.

[0097] like Figure 31 As shown, the first type of beam structure includes: a rectangular core tube 1001, insert plates 1002 vertically welded to the four walls of the rectangular core tube 1001, support wedges 1003 inserted into the insert plates 1002, and a first outer peripheral plate 1004 sleeved on the outside of the rectangular core tube 1001. The connection ends of the insert plates 1002 and the support wedges 1003 are provided with multiple protruding edges 1005, and the support wedges 1003 are provided with an equal number of insertion slots 1006 corresponding to the protruding edges 1005. The number of support wedges 1003 is the same as the number of insert plates 1002, and multiple support wedges 1003 are arranged in a one-to-one correspondence with multiple insert plates 1002. (See reference...) Figure 31 The rectangular core tube 1001 has four insert plates 1002 around its perimeter, and four support wedges 1003 correspond one-to-one with the four insert plates 1002. The four insert plates 1002 are spaced apart along the length of the rectangular core tube 1001 on its four walls. The support wedges 1003 have three insertion slots 1006, and the insert plates 1002 have three protruding edges 1005, which are inserted into the corresponding insertion slots 1006 on the support wedges 1003. The support wedges 1003 are inserted into the protruding edges 1005 through the insertion slots 1006 and are fixedly connected by welding. The first outer plate 1004 surrounds the rectangular core tube 1001 with the support wedges 1003, and the first outer plate 1004 is fixedly connected to the support wedges 1003 by bolts, thereby enclosing the rectangular core tube 1001.

[0098] like Figure 32The second type of beam structure, as shown, includes a core column 1101, radial spokes 1102, and a second outer perimeter plate 1104. An outer perimeter tube is fitted over the core column 1101, and the radial spokes 1102 are supported between the core column 1101 and the outer perimeter tube. In some embodiments, the radial spokes 1102 include a base plate and two webs located on opposite sides of the base plate, the two webs being V-shaped. The base plate is fixed to the core column 1101, and each web extends outward along the four corners of the core column 1101. An open groove is formed between adjacent webs and the base plate, and multiple wedges 1103 are arranged at intervals within the open groove. The second outer perimeter plate 1104 is fixedly connected to the wedges 1103 by bolts. In some embodiments, there are four radial webs, and the four radial spokes 1102 are welded to the edges at the four corners of the core column 1101. The wedge block 1103 comprises three interconnected plates: a first plate, a second plate, and a third plate. The first and second plates are arranged in parallel, and the third plate is connected between the first and second plates, forming an I-shape. The first plate is bolted to the core post 1101, the second plate is connected to the second outer peripheral plate 1104, and one end of the third plate is welded to the first plate, while the other end is welded to the second plate. The welding method involves first welding the third plate to the first plate, securing the connection by welding the gap between the first and third plates. Then, multiple snap-fit ​​protrusions are formed on the top of the third plate, and corresponding connecting grooves are formed on the second plate at the positions of these protrusions. The snap-fit ​​protrusions are then embedded into the connecting grooves and welded in place, thus resolving connection issues arising from positional interference.

[0099] In this embodiment, the supply room pillar 411, door pillar 1, first vertical support pillar 23, and other pillars used in this embodiment can adopt one or more of the following two pillar structures.

[0100] like Figure 33As shown, the first type of column structure includes: a first central column 1201, radial support plates 1202, and a first outer surrounding plate 1203. The first outer surrounding plate 1203 is sleeved on the outside of the first central column 1201, and the radial support plates 1202 are supported between the first outer surrounding plate 1203 and the first central column 1201. In some embodiments, the radial support plates 1202 are plate-shaped, and there are four of them. The four radial support plates 1202 are welded to the four edges of the first central column 1201, thereby forming a mounting groove between two adjacent radial support plates 1202. In some embodiments, the radial support plates 1202 are bent into an open groove shape, and two radial support plates 1202 are fixed to the opposite surfaces of the first central column 1201, thereby dividing the cavity between the first central column 1201 and the first outer surrounding plate 1203 into four mounting grooves. Multiple connecting wedges 12041103 are arranged at intervals within the mounting groove. The first outer enclosure plate 1203 and the connecting wedges 12041103 are bolted together.

Specifically, multiple male insert plates 1304 are arranged in first, third, fifth, etc., positions, and multiple female insert plates 1305 are arranged in second, fourth, sixth, etc., positions, thus creating an alternating connection between the male insert plates 1304 and the female insert plates 1305. Figure 35 and Figure 36As shown, the plug-in male plate 1304 includes a first plug-in plate 1341, multiple rows of first steel trusses 1342 laid on one side of the plug-in plate, a first protruding bolt 1343 located between two rows of first steel trusses 1342, and butt reinforcing bars 1344 located at the connecting end of the plug-in male plate 1304. Parallel-arranged welding seats for the first butt reinforcing bars 1344 are fixedly connected to the first plug-in plate 1341. The welding seats for the first butt reinforcing bars 1344 have V-grooves, and the butt reinforcing bars 1344 are welded into the V-grooves and extend outward from the connecting end of the plug-in male plate 1304 to form a plug-in section. The first protruding bolt 1343 is perpendicular to the inner wall of the first plug-in plate 1341 and abuts against the outer wall of the second central column 1301. Figure 35 and Figure 36 As shown, the female connector 1305 includes a second connector plate 1351, multiple rows of second steel trusses 1352 laid on the surface of the second connector plate 1351, a second protruding bolt 1353 located between the two rows of second steel trusses 1352, and a butt joint pipe 1354 located at the connecting end of the female connector 1305. Multiple butt joint pipes 1354 are arranged in parallel and fixed to the second connector plate 1351. The insertion sections of the butt reinforcing bars 1344 are inserted into the butt joint pipes 1354 and welded in place. The first connector plate 1341 and the second connector plate 1351 are butt-jointed and welded together for sealing. Grouting pipes are provided on the inner sides of the male connector plate 1304 and the female connector 1305. Grouting holes communicating with the grouting pipes are opened on the outer walls of the male connector plate 1304 and the female connector 1305, through which cement or other materials are injected.

[0103] It should be noted that the prefabricated UAV hub platform provided in this application is mainly made of steel plates. (See reference...)

The inner side of the grid 52 refers to the side of the grid 52 facing the center of the platform 3. The buffer posts 532 are fixed to the connecting base 531. Figure 43 As shown, the connecting base 531 is rectangular, and four buffer posts 532 are located at the four corners of the connecting base 531. The buffer posts 532 are made of buffer material. (See reference...) Figure 2 and Figure 3 Only the two ends of the platform 3 located on the drone's glide path are equipped with buffer structures 53, and the other parts of the fence 5 located on the other two sides of the platform 3 are protected only by grid 52.

[0106] like Figure 2 , Figure 3 and Figure 4 As shown, a forced landing structure 6 is installed on the platform 3, and the forced landing structure 6 is located inside the fence 5.
