[0002] Scenic caves are unique geological landscapes sculpted by nature over countless years, typically hidden deep within mountains. They come in diverse forms, some spacious and grand like palaces, accommodating numerous visitors to stroll and admire the wondrous rock textures and shapes on the cave ceilings and walls; others winding and secluded, with meandering paths inviting exploration. The caves possess unique ecosystems, possibly inhabited by rare cave-dwelling creatures. Their geological structures are complex, with varying rock properties; some rocks are solid and stable, while others are more fragile and easily weathered. Furthermore, underground waterways are often present within the caves, their flowing water adding a touch of dynamism and attracting numerous visitors to experience the wonders of nature. Therefore, protective structures are necessary to enhance visitor safety.
[0003] However, the current safety protection structure for scenic caves has the following shortcomings: Inconvenient disassembly of protective netting: Current scenic cave protective netting often uses fixed installation methods, with complex connection structures and a lack of convenient disassembly designs. For example, overly tight clips and a lack of specialized tools make replacement time-consuming and laborious for staff, affecting maintenance progress and hindering timely updates to ensure safety.

[0026] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a safety protection structure for a scenic cave, comprising a cave 1. Multiple protective nets 2 for intercepting gravel are installed on the inner top side of the cave 1. Fixing plates 7 are fixedly connected to both sides of the protective nets 2. Fixing components are installed on the inner wall of the cave 1 to fix the fixing plates 7 into the cave 1. Multiple protective pipes 6 are fixedly connected inside the cave 1. Protective rods 15 are connected inside the protective pipes 6. A crossbar 16 is fixedly connected to the top of the protective rod 15, and a telescopic rod 14 is fixedly connected to the bottom of the crossbar 16. The bottom end of the telescopic rod 14 is fixedly connected inside the cave 1. A guardrail is formed by the protective pipes 6, protective rods 15, telescopic rods 14, and crossbars 16, thereby preventing tourists from falling into the waterway in the cave 1. A water level monitor 5 is installed inside the cave 1 to monitor the water level in the waterway in real time. If the water level rises too quickly or the water pressure increases abnormally, it may indicate that the stability of the cave structure is affected, and a timely warning will be issued so that the scenic area can take countermeasures such as limiting visitor numbers and reinforcing the structure. Figure 2 and Figure 3 Inside the cavern 1, a bottom plate 8 and a top plate 9 are fixedly connected. A fixed pipe 10 is fixedly connected to the top side of the bottom plate 8. The fixed pipe 10 is inserted into the inside of the fixed plate 7. A rod 11 is slidably connected inside the fixed pipe 10. The top end of the rod 11 is inserted into the inside of the top plate 9. By inserting the rod 11 into the top plate 9, the bottom plate 8 and the top plate 9 are connected, thereby hooking the fixed plate 7 and preventing the fixed plate 7 from detaching from the bottom plate 8 and the top plate 9. A handle 13 is rotatably connected to the bottom side of the bottom plate 8 through a damping shaft. A threaded rod 12 is threadedly connected to the rod 11. The bottom end of the threaded rod 12 is rotatably connected to the inside of the bottom plate 8, and the bottom end of the threaded rod 12 is fixedly connected to the inside of the handle 13. The handle 13 is used to rotate the threaded rod 12, thereby driving the rod 11 to slide inside the fixed pipe 10, so that the rod 11 can detach from or insert into the top plate 9.
[0027] Reference Figure 1 , Figure 4 and Figure 5Two rings 17 are rotatably connected to the outer wall of the protective rod 15. The rings 17 are slidably connected inside the protective tube 6. A limit rod 18 is fixedly connected to the outer wall of the rings 17. The outer wall of the protective tube 6 has a sliding groove and multiple limit grooves. The limit rod 18 is slidably connected inside the sliding groove and engages inside the limit groove. By engaging the limit rod 18 into the limit groove, the position of the protective rod 15 is fixed in the protective tube 6. Baffles 19 are slidably connected inside the two limit grooves on the top side. A keyhole 20 is provided on the outer wall of the protective tube 6. The keyhole 20 is inserted by sliding the baffle 19. The limit rod 18 is either inserted into or removed from the limit groove, thus blocking the limit rod 18 in the limit groove, or the limit groove is exposed so that the limit rod 18 can be removed from the limit groove. The baffle 19 can be slid by the key in the corresponding keyhole 20 to prevent the protective rod 15 from falling out of the protective pipe 6 due to the visitor's accidental operation. Multiple warning signs 3 are fixedly connected to the inner wall of the cave 1. A drainage ditch is opened inside the cave 1. A cover plate 4 is set on the top side of the drainage ditch. The cover plate 4 has water permeable holes. The warning signs 3 indicate "Danger area, do not approach", "Beware of falling rocks", "Be careful of slipping" and other warnings. The drainage ditch collects the water flowing down the cave wall to prevent water from accumulating and causing excessive water accumulation in the cave 1.
[0028] Working principle: First, a drainage ditch is dug along the inner wall of cave 1, close to one side of the inner wall. Then, a cover plate 4 with permeable holes is placed over the drainage ditch to collect water flowing down the cave wall, preventing excessive water accumulation in cave 1. Next, a guardrail formed by the protective pipe 6, protective rod 15, telescopic rod 14, and crossbar 16 is installed on the bank near the waterway. Then, the ring 17 is rotated to disengage the limiting rod 18 from the two limiting slots on the bottom side and rotate it into the sliding groove. Then, the crossbar 16 is pulled to slide the protective rod 15 upwards, allowing it to slide out of the protective pipe 6. The ring 17 is then rotated again to rotate the limiting rod 18 into the two limiting slots on the top side. Then, the key corresponding to the keyhole 20 is inserted into the keyhole 20 to allow the baffle 19 to slide. The baffle 19 is then slid into the bottom of the two limiting slots on the top side, thus fixing the position of the protective rod 15. When it is necessary to lower the protective rod 15... When the height of the guardrail is lowered to facilitate maintenance of the waterway, the above process can be repeated in reverse, which will not be elaborated here. Then, using some climbing tools such as ladders, the bottom plate 8 and the top plate 9 are fixed to the inner wall of the cave 1. Then, the protective net 2 is pulled to the corresponding positions of the bottom plate 8 and the top plate 9. Then, the fixing plate 7 is placed between the bottom plate 8 and the top plate 9 and inserted into the fixing pipe 10. Then, the handle 13 is turned to rotate the threaded rod 12, which drives the insertion rod 11 to slide inside the fixing pipe 10, so that the insertion rod 11 is disengaged from or inserted into the top plate 9, thereby hooking the fixing plate 7 and preventing the fixing plate 7 from falling between the bottom plate 8 and the top plate 9. The installation of the protective net 2 is completed, thereby intercepting the falling rocks above the cave 1. Finally, the warning sign 3 with warning slogans is fixed to the inner wall of the cave 1, and the water level monitor 5 is installed on the waterway to monitor the water level in real time.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
