Description

Technical Field

[0001] This invention relates to the field of geological disaster prevention and control technology, specifically to a multi-level, multi-layer anti-sliding and drainage combined structure for red-bed landslides in mountainous areas. Background Technology

[0002] Mountain red beds refer to strata distributed in mountainous areas, composed of red terrestrial clastic rocks and claystones. Their lithology is weak and easily softened when exposed to water. They often have multiple weak interlayers or weak surfaces, making them highly susceptible to multi-level and multi-stage landslides under the influence of rainfall and gravity. A landslide is a geological phenomenon in which soil or rock masses on a slope slide slowly or rapidly downward or forward along a certain weak surface or sliding zone under the influence of gravity, influenced by factors such as groundwater, rainfall, earthquakes, or human engineering activities. The multi-level and multi-layer anti-sliding and drainage combined structure for red bed landslides in mountainous areas is a comprehensive treatment structure that integrates anti-sliding, anchoring, drainage and assembly, designed to address the multi-level and multi-layer potential instability characteristics of red bed slopes in mountainous areas. It aims to improve the stability of red bed slopes, quickly drain accumulated water and facilitate later maintenance. Therefore, a multi-level and multi-layer anti-sliding and drainage combined structure for red bed landslides in mountainous areas is needed. In existing technologies, the anti-sliding and drainage structures for landslide control are mostly installed as a whole with fixed installation. The components are connected by welding or integral casting, which makes it difficult to disassemble and assemble flexibly during use. This makes it difficult to replace and clean vulnerable components such as the base plate individually, resulting in low maintenance efficiency and affecting the long-term use effect of the structure. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a multi-level, multi-layer anti-sliding and drainage combined structure for red-bed landslides in mountainous areas, which solves the problem that most anti-sliding and drainage structures for landslide control adopt an integral fixed installation, making flexible disassembly and assembly impossible.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-level, multi-layer anti-sliding and drainage combined structure for red-layer landslides in mountainous areas, comprising a positioning frame, a sliding frame slidably connected to the inner wall of the positioning frame, a base plate slidably connected to the inner wall of the sliding frame, a cylinder I threadedly connected to the bottom of the positioning frame, a pin hole I and a pin hole II respectively opened on the side wall of the cylinder I, a cylinder II slidably connected to the positioning frame, the sliding frame, the base plate and the inner wall of the cylinder I, a rotating shaft rotatably connected to the top of the cylinder II, a knob fixedly connected to the top end of the rotating shaft, a limiting ring fixedly connected to the outer wall of the cylinder II, a gear fixedly connected to the bottom end of the rotating shaft, a rack meshing with the tooth end of the gear, a pin fixedly connected to the end of the rack, a limiting plate fixedly connected to the end of the pin, the outer wall of the limiting plate slidably connected to the inner walls of the pin hole I and the pin hole II, and a splicing assembly provided on the outer wall of the base plate.

[0005] Preferably, the splicing assembly includes a protrusion, the outer wall of which is fixedly connected to one side of the base plate, and a groove is provided on the other side of the base plate. The outer wall of the protrusion is slidably connected to the inner wall of the groove, and bolts are threaded through the interior of both the groove and the protrusion.

[0006] Preferably, the outer wall of the insertion post is slidably connected to the inside of the first insertion hole, the second insertion hole, and the second cylinder, respectively.

[0007] Preferably, a sliding groove is provided on the side wall of the first cylinder, a connecting column is slidably connected inside the first cylinder, and a connecting block is fixedly connected to the outer wall of the connecting column.

[0008] Preferably, one end of a connecting rod is rotatably connected inside the connecting block, the other end of the connecting rod is rotatably connected inside the connecting block, and an arc plate is fixedly connected to the outer wall of the connecting block.

[0009] Preferably, the outer wall of the arc plate is fixedly connected with an anti-slip block, the upper surface of the base plate is provided with a drainage groove, and the upper surface of the base plate is fixedly connected with an anti-slip strip.

[0010] Preferably, a connecting box is fixedly connected to the lower surface of the base plate, a rotating column is rotatably connected inside the connecting box, a support column is fixedly connected to the end of the rotating column, and a pin is threaded to the bottom end of the support column.

[0011] Preferably, a disc is fixedly connected to the outer wall of the rotating column, and the outer wall of the disc is rotatably connected to the inside of the connecting box. A slot is provided on the outer wall of the disc.

[0012] Preferably, a cylindrical block is fixedly connected inside the connecting box, a rectangular block is slidably connected to the inner wall of the cylindrical block, the outer wall of the rectangular block is slidably connected to the inner wall of the slot, a handle is fixedly connected to the outer wall of the rectangular block, and the outer wall of the handle is slidably connected to the inside of the cylindrical block.

[0013] Preferably, the outer wall of the handle is provided with a spring, one end of which is fixedly connected to the outer wall of the rectangular block, and the other end is fixedly connected to the inner wall of the cylinder.

[0014] Working Principle: When this structure is needed, first place the positioning frame in the pre-dug hole on the landslide slope using cylinder one to complete the initial positioning and alignment of the overall structure, providing a reference for the subsequent installation of multi-level and multi-layer structures. Then, embed the sliding frame into the positioning frame, and then smoothly slide the base plate along the inner wall of the sliding frame. Subsequently, the angle of the support column can be adjusted according to the slope inclination. First, pull the handle, which drives the rectangular block to slide on the inner wall of cylinder three. At the same time, the rectangular block compresses the spring. When the outer wall of the rectangular block is completely separated from the inner wall of the slot, rotate the support column, which in turn drives the rotating column to rotate. The rotating column drives the disc to rotate inside the connecting box. When it rotates to the specified angle, release the handle. The reaction force of the spring drives the rectangular block to lock into the slot, thus fixing the support column and achieving the adjustment. The tilt angle of the support column is designed to adapt to different slope inclinations. After the angle of the support column is adjusted, it is immediately inserted into the surface soil of the slope. The pins at the bottom of the support column penetrate deep into the soil, forming a shallow anti-slip anchoring system. Through the threaded connection between the pins and the support column, the pins can be quickly replaced individually after wear, bending, or corrosion without dismantling the entire structure, greatly improving the convenience of later operation and maintenance. Multiple drainage channels are opened on the upper surface of the base plate. During rainfall, the slope runoff can be quickly and directionally guided and discharged along the drainage channels, preventing rainwater from accumulating on the slope and infiltrating, which would soften the red soil and reduce the risk of landslides from the source. The anti-slip strips set on the upper surface of the base plate can significantly improve the surface friction coefficient of the structure, ensuring the safety of construction and inspection personnel and also hindering the sliding of the shallow loose soil on the slope to a certain extent, achieving the dual functions of shallow anti-slip and drainage. Addressing the need for large-scale, long-distance red-bed landslide control in mountainous areas, this structure features flexible expansion capabilities. Protrusions on one side of adjacent base plates are aligned with grooves on another base plate and pushed horizontally in, ensuring a tight fit. Bolts are then inserted through the top of the grooves and tightened, forming a rigid whole from multiple base plates. Multiple units are sequentially assembled, and with the support columns and anchors at their respective bases, a continuous, integrated, and high-strength multi-layered anti-sliding and drainage barrier is formed. This multi-layered structure can resist the sliding thrust of soil at different depths. The upper layer resists shallow slope slippage, the middle layer bears the main anti-sliding role, and the lower layer connects to the deep anchoring structure, achieving a multi-level stress, multi-layered protection, and comprehensive drainage control effect. After the overall positioning and splicing are completed, cylinder two is inserted from the top of the positioning frame through the sliding frame and the center hole of the base plate until the bottom end extends into the internal cavity of cylinder one. When the insert pin moves to the corresponding pin hole position, the knob is turned to drive the rotating shaft and gear to rotate. The gear drives the racks on both sides to move radially outward. The racks push the insert pin and the end limiting plate out of cylinder two and through the pin hole of cylinder one until the limiting plate is flush with the outer wall of cylinder one, thus achieving rigid locking between cylinder two and cylinder one. This connects the positioning frame, sliding frame, and base plate into a stable middle-layer locking system, ensuring the coordinated work of multi-level and multi-layer structures. When the base plate needs to be inspected, cleaned, or replaced, simply turn the knob in the opposite direction to make the gear and rack drive the insert pin and the limiting plate to retract. After unlocking, cylinder two can be pulled out, and the splicing bolts can be loosened to remove the base plate separately, achieving quick disassembly and quick maintenance, and significantly reducing the later maintenance cost of mountain slope treatment. To further enhance the anchoring capacity of the structure in deep soil and prevent cylinder one from being pulled out or becoming unstable, cylinder one can be deeply reinforced. After the initial lock is released by rotating the knob in the opposite direction, cylinder one is pressed down, causing cylinder two to move the connecting column downward. The connecting column drives the connecting block to move synchronously, and the connecting block drives the connecting rod to rotate in the groove and extend outward, thereby pushing the arc plate to gradually open. The anti-slip block on the outside of the arc plate is embedded in the surrounding soil to form multi-point, large-area anchoring, which significantly increases the contact area and frictional resistance between cylinder one and the soil, forming a deep anchoring system. When the insert reaches the secondary locking position, the limiting ring is flush with the surface of the positioning frame. Rotating the knob again makes the insert engage the corresponding hole, realizing the limiting and fixing of the arc plate and the anti-slip block. Finally, a multi-level, multi-layer anti-slip system is formed, consisting of shallow anti-slip drainage, middle-layer overall locking, and deep multi-point anchoring. This structure achieves multi-level and multi-layer anti-sliding while integrating drainage function throughout the entire structure and process. It quickly drains rainwater from the slope through drainage channels on the bottom plate surface, and forms an internal drainage channel with the central cylinder through the gaps between the multi-layer splicing, preventing rainwater from infiltrating and softening the weak red layer. It truly realizes the integration of anti-sliding, anchoring, drainage, maintenance and expansion, and greatly improves the safety, durability and practicality of red layer landslide treatment in mountainous areas.

[0015] This invention provides a multi-level, multi-layered anti-sliding and drainage composite structure for red bed landslides in mountainous areas. It has the following beneficial effects: 1. This invention uses a cylindrical tube that passes through a positioning frame, a sliding frame, and a base plate and extends into a cylindrical tube. Rotating a knob drives a rotating shaft, gears, and a rack to work together, pushing the insert pin and the limiting plate through the pin hole to form a locking engagement. By rotating the knob in the opposite direction, the lock is released and the cylindrical tube is removed. This invention provides convenient locking and unlocking of the base plate, enabling quick removal of the base plate for replacement or cleaning, thus improving maintenance efficiency.

[0016] 2. This invention unlocks the cylinder by rotating the knob counterclockwise, causing the second cylinder to move downwards and the connecting column to move downwards. This, along with the connecting block and connecting rod, causes the arc plate to open and the anti-slip block to embed into the soil. Rotating the knob clockwise then causes the insert to engage with the corresponding hole and lock in place. This reinforces the first cylinder and creates multi-point anchoring, increasing the frictional resistance with the soil, preventing the first cylinder from being pulled out, and simultaneously limiting and fixing the arc plate and the anti-slip block, thus improving the overall structural stability.

[0017] 3. This invention aligns and fits the protrusions and grooves of adjacent base plates, and fixes them with bolts to form a rigid connection between the adjacent base plates. Then, multiple base plates are connected in sequence through splicing components. With the cooperation of the support columns and pins at the bottom of each base plate, it can expand the treatment range, enhance the effect of large-area landslide treatment, and improve the overall stability of the slope.

[0018] 4. This invention performs initial positioning by placing the positioning frame in the predetermined hole, and then installs the sliding frame and the base plate in sequence, so that the support column is inserted into the slope and the pin is inserted into the soil. The threaded connection between the support column and the pin facilitates replacement. At the same time, the drainage channel is used to divert the slope runoff, and the anti-slip strip increases friction, which plays a role in diverting rainwater and ensuring walking safety. It achieves the effects of avoiding soil softening, preventing people from slipping, and facilitating maintenance.

[0019] 5. This invention allows the rectangular locking block to slide and compress the spring by pulling the handle. After releasing the locking, the support column is rotated, causing the rotating column and the disc to rotate to a specified angle. Then, the spring reaction force is used to reset the rectangular locking block and lock the support column, which can flexibly adjust the tilt angle of the support column. This achieves the effects of adapting to different inclined slopes, ensuring the stable layout of the structure, and improving the adaptability of the structure. Attached Figure Description

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a multi-level, multi-layer anti-sliding and drainage combined structure for red-layer landslides in mountainous areas, including a positioning frame 1, a sliding frame 2 slidably connected to the inner wall of the positioning frame 1, a base plate 3 slidably connected to the inner wall of the sliding frame 2, a cylinder 4 threadedly connected to the bottom of the positioning frame 1, and pin holes 5 and 6 respectively opened on the side walls of the cylinder 4. A cylinder 7 slidably connected to the inner walls of the positioning frame 1, sliding frame 2, base plate 3 and cylinder 4, a rotating shaft 8 rotatably connected to the top of the cylinder 7, a knob 9 fixedly connected to the top of the rotating shaft 8, a limiting ring 10 fixedly connected to the outer wall of the cylinder 7, a gear 11 fixedly connected to the bottom end of the rotating shaft 8, a rack 12 meshing with the tooth end of the gear 11, a pin 13 fixedly connected to the end of the rack 12, a limiting plate 14 fixedly connected to the end of the pin 13, and the outer wall of the limiting plate 14 slidably connected to the inner walls of pin holes 5 and 6. A splicing assembly is provided on the outer wall of the base plate 3. Specifically, the sliding cooperation between positioning frame 1 and sliding frame 2 enables the overall structure to flexibly adapt to different terrain conditions on the red bed slope in mountainous areas, achieving the effects of reasonably adjusting the installation position, optimizing the stress distribution, and significantly improving the on-site adaptability of the structure. The sliding cooperation between base plate 3 and sliding frame 2 enables the disassembly and convenient relocation of base plate 3, facilitating individual inspection and replacement, timely removal of silt and debris, ensuring unobstructed drainage channels, and reducing the difficulty and cost of later maintenance. The coaxial sliding cooperation between cylinder 1 4 and cylinder 2 7 enables precise docking and coaxial positioning of the anchoring components, achieving high installation alignment accuracy, smooth connection between upper and lower components, and improved overall construction quality. The linkage between knob 9 and rotating shaft 8... The rotation of the gear 11 ensures smooth and synchronous rotation, achieving stable power input, balanced transmission on both sides, and preventing jamming or uneven loading. Through the meshing of the gear 11 and rack 12, the insert pin 13 and the limiting plate 14 move synchronously, enabling quick locking or unlocking with the first and second pin holes 5 and 6, achieving reliable locking and convenient unlocking, and significantly improving assembly and disassembly efficiency. The limiting ring 10 controls the insertion depth of the cylinder 2 7, preventing excessive insertion, ensuring precise installation positioning, reasonable anchoring depth, and protection of the internal mechanism from damage. The multi-stage engagement of the insert pin 13 with the first and second pin holes 5 and 6 enables multi-level height adjustment and double locking. The positioning frame 1, sliding frame 2, base plate 3, and anchoring components work together to achieve the effect of adapting to different burial depths and slope conditions, improving the versatility and stability of the structure. Through the coordinated operation of the positioning frame 1, sliding frame 2, base plate 3, and anchoring components, it drives the orderly combination and collaborative work of multi-level and multi-layer structures, achieving a multi-level and multi-layer anti-slip effect: shallow slope anti-slip, mid-layer overall locking, and deep soil anchoring. Simultaneously, in conjunction with the drainage channels 21 and anti-slip strips 22 on the base plate 3, it enables rapid drainage of rainwater from the slope, reduces water infiltration and softens the red soil, allowing anti-slip and drainage functions to be performed simultaneously, resulting in more uniform overall stress and significantly enhanced resistance to landslides in mountainous red soil areas. Through the mutual cooperation of various components, it can quickly adapt to complex on-site construction conditions and work stably for a long time, effectively improving the anti-slip effect of mountainous red soil slopes. To ensure safety and durability, the limiting plate 14 can slide into the interior of cylinder 2 7, but cannot slide off cylinder 2 7. A limiting frame is fixedly connected to the inner wall of cylinder 2 7, and the outer wall of rack 12 is slidably connected to the inner wall of the limiting frame. Through the limiting frame on the inner wall of cylinder 2 7, rack 12 is smoothly slid along a fixed trajectory, achieving the effect of limiting rack 12 offset and ensuring precise meshing with gear 11. The limiting frame effectively constrains the sliding direction of rack 12, preventing rack 12 from skewing or misaligning during telescopic movement, preventing it from detaching from gear 11, ensuring stable operation of the transmission mechanism, and ensuring reliable execution of locking, unlocking, anchoring, and deployment actions. This allows the entire multi-level, multi-layer anti-slip drainage composite structure to work continuously and stably in complex geological environments.It achieves both layered and zoned resistance to landslide thrust, and efficient drainage and load reduction throughout the entire process, truly realizing integrated anti-slide and drainage, convenient installation and maintenance, and long-term adaptability and protection.

[0024] Please see the appendix Figure 1 and attached Figure 8 The splicing component includes a protrusion 24. The outer wall of the protrusion 24 is fixedly connected to one side of the base plate 3. A groove 23 is provided on the other side of the base plate 3. The outer wall of the protrusion 24 is slidably connected to the inner wall of the groove 23. Bolts 25 are threaded through the interior of both the groove 23 and the protrusion 24. Specifically, the interlocking of the groove 23 on one side of the base plate 3 with the protrusion 24 on the other side ensures precise alignment and neat connection between multiple base plates 3, achieving a combined structural splicing, a regular overall layout, and facilitating large-area paving construction. The tight cooperation between the protrusion 24 and the groove 23 ensures stable overlap between adjacent base plates 3, constraining relative displacement, reducing splicing gaps, preventing soil seepage, and improving structural integrity. The bolts 25, which tighten the groove 23 and protrusion 24, connect the independent base plates 3 into a rigid whole, achieving coordinated force distribution, dispersing landslide thrust, and improving overall deformation resistance. The reliable connection of the splicing components forms a continuous protection system for the multi-level, multi-layer anti-slide structure, expanding the protection range, enhancing overall structural rigidity, and improving slope stability. After splicing, multiple base plates 3 form a continuous and flat row. The water surface, in conjunction with the drainage channel 21, allows rainwater on the slope to flow smoothly without accumulation or leakage. While achieving multi-level and multi-layer anti-sliding, it also ensures efficient drainage, weakening the softening effect of water on the red soil from the source and further enhancing the overall protection effect. The combined use of grooves 23, protrusions 24, and bolts 25 facilitates the rapid assembly and secure locking of the combined structure, achieving convenient installation, high connection strength, simple maintenance, and extended service life. Multiple base plates 3 can be set to form a layered resistance and multi-level stress anti-sliding system. The upper layer restrains the slippage of shallow soil, the middle layer bears the main landslide thrust, and the lower layer works in conjunction with the deep anchoring structure to truly achieve multi-level and multi-layer collaborative protection. The splicing components are reasonably laid out and reliably connected, enabling rapid splicing between base plates 3 and significantly improving the overall structure's anti-sliding bearing capacity and drainage smoothness, providing stable, continuous, and efficient protective support for mountain red slopes.

[0025] Please see the appendix Figure 6 and attached Figure 7 The outer walls of the insert 13 are slidably connected to the inside of the first insert hole 5, the second insert hole 6, and the second cylinder 7, respectively; Specifically, the engagement of the insert post 13 with the first pin hole 5 serves to initially position the first cylinder 4 and the second cylinder 7, achieving rapid alignment and convenient installation. The engagement of the insert post 13 with the second pin hole 6 ensures deep locking of the entire structure, achieving a firm connection and improved overall stability. The sliding of the insert post 13 within the second cylinder 7 allows for flexible extension and retraction of the pin, enabling quick switching between locked and unlocked states and facilitating disassembly and maintenance. Through the cooperation of various components, accurate positioning and reliable locking effectively improve the installation efficiency and safety of the mountain red-layer landslide protection structure.

[0026] Please see the appendix Figure 4 -Appendix Figure 6 The side wall of cylinder 4 is provided with a sliding groove 15, and a connecting column 16 is slidably connected inside cylinder 4; a connecting block 17 is fixedly connected to the outer wall of the connecting column 16; one end of a connecting rod 18 is rotatably connected inside the connecting block 17, and the other end of the connecting rod 18 is rotatably connected inside the connecting block 17; an arc plate 19 is fixedly connected to the outer wall of the connecting block 17; and an anti-slip block 20 is fixedly connected to the outer wall of the arc plate 19. Specifically, the groove 15 on the side wall of cylinder 4 facilitates the smooth sliding of the connecting block 17, ensuring the orderly opening and stable, uninterrupted movement of the arc plate 19. This guarantees a smooth and reliable deployment of the anchoring mechanism. The up-and-down movement of the connecting column 16 drives the linkage between the connecting block 17 and the connecting rod 18, achieving synchronous opening of the arc plate 19, uniform force distribution, and prevention of localized damage, effectively extending the service life of the mechanism. The rotation and pushing of the connecting rod 18 causes the arc plate 19 to unfold outward, expanding the anchoring range, increasing soil grip, and enhancing anchoring depth, thus better adapting to mountainous red soil. In complex soil environments characterized by weak and easily softened layers, the anti-sliding block 20 on the outer wall of the arc plate 19 increases the interlocking friction with the soil, thereby strengthening the anchoring effect and effectively preventing the cylinder 1 4 from being pulled out by the landslide thrust. This significantly improves the reliability of deep anti-slide protection. The downward pressing action of the cylinder 2 7 drives the connecting column 16 to move down and trigger the deployment mechanism, achieving rapid anchoring of deep soil and shortening construction time, thus significantly improving on-site construction efficiency. The secondary engagement of the insert column 13 and the pin hole 2 6 locks the deployed structure, achieving double anchoring from top to bottom, making the overall structure more stable and stronger in resisting landslides.

[0027] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 9The upper surface of the base plate 3 is provided with a drainage groove 21, and the upper surface of the base plate 3 is fixedly connected with an anti-slip strip 22; the lower surface of the base plate 3 is fixedly connected with a connecting box 28, the inside of the connecting box 28 is rotatably connected with a rotating column 29, the end of the rotating column 29 is fixedly connected with a support column 26, and the bottom end of the support column 26 is threaded with a pin 27. Specifically, the drainage channels 21 on the base plate 3 quickly drain rainwater from the slope and guide the orderly discharge of water, reducing water infiltration, preventing long-term rainwater immersion and softening of the red bed soil, and maintaining the overall stability of the slope soil. The drainage channels 21 are arranged along the slope, quickly collecting and draining surface water during rainfall, reducing the deteriorating impact of water on the red bed rock mass from the source, and providing a stable working environment for the multi-level, multi-layered anti-slip structure. The anti-slip strips 22 on the base plate 3 increase the surface friction resistance of the structure and enhance the safety of the slope protection, ensuring the safety of construction and inspection personnel and preventing slippage. As a result, through the cooperation of the support column 26 and the pin 27, the support column 26 and the pin 27 can be deeply anchored in the soil and resist the slippage of shallow soil. This enhances the anti-slip ability of the base plate 3 and improves the overall stability of the structure. The support column 26 and the pin 27 form a multi-layer, multi-point shallow anchoring system, which works in conjunction with the middle layer locking structure and the deep anchoring mechanism to form a complete multi-level, multi-layer anti-slip system. The landslide thrust is distributed layer by layer. Through the threaded cooperation between the pin 27 and the support column 26, the wear parts can be replaced quickly without the need to dismantle the entire structure. This reduces maintenance costs, shortens maintenance time, and extends the service life of the structure.

[0028] Please see the appendix Figure 9 and attached Figure 10 A disc 30 is fixedly connected to the outer wall of the rotating column 29. The outer wall of the disc 30 is rotatably connected to the inside of the connecting box 28. A slot 31 is provided on the outer wall of the disc 30. A spring 35 is provided on the outer wall of the handle 34. One end of the spring 35 is fixedly connected to the outer wall of the rectangular block 33, and the other end is fixedly connected to the inner wall of the cylindrical block 32. Specifically, pulling the handle 34 causes the rectangular locking block 33 to slide along the inner wall of the cylinder 32, thus compressing the spring 35 and releasing the rectangular locking block 33 from the slot 31. This creates conditions for adjusting the angle of the support column 26. The rectangular locking block 33 compresses the spring 35, causing it to store elastic potential energy, allowing for quick re-engagement after releasing the handle 34, ensuring timely fixation after angle adjustment. The rotation of the support column 26 causes the rotating column 29 to rotate synchronously, thus rotating the disc 30 inside the connecting box 28, adjusting the tilt angle of the support column 26. The flexible adjustment, through the rotation of the disc 30, drives the synchronous shift of the slot 31, achieving the effect of adapting to different engagement positions of the rectangular block 33 and meeting the fixing requirements of different tilt angles. Through the reaction force of the spring 35, the rectangular block 33 is reset and locked into the corresponding slot 31, achieving the effect of quickly locking the angle adjustment of the support column 26 and preventing the support column 26 from loosening or shifting. Through the coordinated cooperation of various components inside the connecting box 28, the support column 26 is flexibly adjusted to adjust the tilt angle, achieving the effect of adapting to different slopes of the red layer in mountainous areas, ensuring the stable installation of the base plate 3, and improving the overall adaptability and stability of the structure.
