Description

Technical Field

[0001] This invention relates to the field of open-pit coal mining technology, specifically to a multi-functional device for slope anti-slip and drainage in open-pit coal mines. Background Technology

[0002] Open-pit coal mines are mines that extract surface or shallow coal resources through direct open-pit mining. They have shallow coal seams and simple geological structures, making them suitable for gently sloping or inclined deposits. Globally, approximately 40% of coal production comes from open-pit mining. Major mining areas in China are located in Inner Mongolia and Shanxi, with representative areas including Huolinhe, Pingshuo Antaibao, and Heidaigou. Pingshuo Antaibao, with reserves of 12.6 billion tons, is China's largest open-pit coal mine. Currently, most open-pit coal mines use protective netting for slope stabilization. However, in cases of severe collapse, a single netting may not be sufficient to prevent large-scale rockfalls, leading to irreparable damage. Furthermore, existing open-pit coal mine slopes rely on ditches for drainage, which are easily clogged by impurities, causing blockages. Ultimately, landslides occur on open-pit coal mine slopes in mountainous areas without early warning, potentially resulting in casualties. Summary of the Invention

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0039] Please see Figure 1-8 This invention provides a technical solution: a multi-functional device for anti-slip and drainage on open-pit coal mine slopes, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the structure includes a slope anti-slip structure 1, which includes a slope body 11. A first protective component 12 and a top protective component 13 are installed on the slope body 11. The top protective component 13 is located on the upper side of the first protective component 12. A second slope protection component 14 is installed on the slope body 11. The first protective component 12 includes a first slope protection net 121, which is installed on the slope body 11 via a fixing rod 122. The top protective component 13 includes a telescopic fixing rod 131, the lower side of which is installed on the slope body 11. The telescopic fixing rod 131 is connected to a hollow threaded connector 1. 32. The height is adjusted. An anti-slip geomembrane body 133 is installed on the upper side of the telescopic fixing rod 131 and is used for top rain protection. A water channel 134 is provided on the anti-slip geomembrane body 133. The second slope protection component 14 includes a support frame 141. Fixing members 142 are fixed on the support frame 141. A second slope protection net 143 is installed between the fixing members 142. A sliding groove 144 is opened on the support frame 141. The position of the connecting plate 145 is adjusted by telescopic structure. A third slope protection net 146 is installed on the connecting plate 145 through the fixing members 142, thereby increasing the width of the second slope protection net 143.

[0040] Among them, the slope body 11 is equipped with a control device for controlling the overall equipment. The telescopic structure in this application is a hydraulic cylinder. Hydraulic cylinders are existing technology. Each set of hydraulic cylinders is equipped with a position sensor to monitor its real-time displacement and transmits these data to the control device through a feedback control system. The control device fine-tunes the hydraulic valves according to the feedback data to ensure that the action of each hydraulic cylinder body is always synchronized.

[0041] Specifically, multiple telescopic fixing rods 131 are provided, and the multiple telescopic fixing rods 131 are distributed at equal intervals on the top of the slope body 11. A protective plate is installed on the top of the telescopic fixing rod 131, and the anti-slip geomembrane body 133 is placed on the protective plate, thereby playing a protective role for the anti-slip geomembrane body 133.

[0042] Furthermore, the support frame 141 is arranged in a triangular shape, and multiple sets of support frames 141 are provided, with the multiple sets of support frames 141 arranged symmetrically.

[0043] In the above scheme, the first slope protection net 121 is placed on the surface of the slope body 11 and fixed by the fixing rod 122. The telescopic fixing rod 131 is fixedly installed on the slope body 11. The length of the telescopic fixing rod 131 is adjusted, and the hollow threaded connector 132 on the telescopic fixing rod 131 is rotated to fix it. The protective plate is installed on the top of the telescopic fixing rod 131, and the anti-slip geomembrane body 133 is installed on the surface of the protective plate to prevent rainwater erosion and sediment loss, maintain slope stability, and allow rainwater to pass through the anti-slip geomembrane body 133. The water flows from the trough 134 on the 3rd floor into the inclined trough 212. If a debris flow or landslide occurs on the slope body 11, the crushed stone rollers will provide secondary protection with the assistance of the second slope protection net 143 between the fixing parts 142 on the support frame 141. If the width of the second slope protection net 143 is insufficient, the third slope protection net 146 on the connecting plate 145 will be moved upward to the required position with the assistance of the hydraulic cylinder on the support frame 141, thereby increasing the width of the second slope protection net 143 and better protecting the crushed stone, thus protecting personnel safety.

[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the slope anti-slip structure 1 is provided with a diversion structure 2 for diversion treatment. The diversion structure 2 includes a drainage component 21. An automatic cleaning component 22 is installed on the drainage component 21 for automatic internal cleaning. The drainage component 21 includes a diversion channel 211, which is connected to an inclined channel 212. Steps 213 are installed on the inclined channel 212, which is connected to a guide channel 214. A sealing plate 215 is installed on the top of the guide channel 214. The automatic cleaning component 22 includes a first motor box 221. The motor in the first motor box 221 drives the screw rod 222 to rotate and is used for automatic conveying of mud and impurities. The screw rod 222 is installed in the guide channel 214, which is connected to a discharge pipe 223.

[0045] Multiple sets of diversion channels 211 and inclined channels 212 are provided. Multiple steps 213 are installed on the inclined channel 212 to facilitate the walking and use of maintenance personnel in the later stage.

[0046] Specifically, the motor inside the first motor housing 221 is a dual-head motor, which is existing technology;

[0047] In the above scheme, rainwater flows through the diversion channel 211 into the inclined channel 212, and finally the wastewater enters the guide channel 214. The sealing plate 215 on the upper side of the guide channel 214 plays an auxiliary sealing role. The staff maintains the inclined channel 212 through the steps 213. With the assistance of the dual-head motor in the first motor box 221, the screw rod 222 is driven to rotate. The rotation of the screw rod 222 drives the impurities to be discharged through the discharge pipe 223.

[0048] like Figure 1 and Figure 4 As shown, the diversion structure 2 is connected to the wastewater circulation structure 3 and is used for wastewater treatment. The wastewater circulation structure 3 includes a filter box 31, in which an impurity pretreatment component 32 is installed and used for impurity treatment. A waste plate 33 is provided on the lower side of the impurity pretreatment component 32. The filter box 31 is connected to the wastewater treatment component 35 through a first drain pipe 34. The wastewater treatment component 35 is connected to the water storage tank 38 through a second drain pipe 36. A ceramic membrane body 37 is installed in the water storage tank 38. The water storage tank 38 is connected to the spray component 39, which is installed on the filter box 31. The impurity pretreatment component 32 includes a water tank pipe 321, which is rotatably connected to a baffle 323 through a rotating ring 322. The baffles 323 are installed between each other. The wastewater treatment assembly 35 includes a wastewater treatment tank 351, which contains a pebble filter layer 352, a quartz sand filter layer 353, a modified fiber ball layer 354, and an activated alumina ball water purification filter layer 355. The quartz sand filter layer 353 is located below the pebble filter layer 352, the modified fiber ball layer 354 is located below the quartz sand filter layer 353, and the activated alumina ball water purification filter layer 355 is located below the modified fiber ball layer 354. The spray assembly 39 includes a water supply pipe 391, which is connected to a high-pressure nozzle 393. The high-pressure nozzle 393 is mounted on a support plate 392.

[0049] Among them, there are two sets of baffles 323, and multiple sets of partition plates 326 are fixed between the two sets of baffles 323. The multiple sets of partition plates 326 are evenly distributed between the baffles 323.

[0050] Specifically, multiple sets of high-pressure nozzles 393 are provided on the support plate 392, and the multiple sets of high-pressure nozzles 393 are distributed at equal intervals on the support plate 392;

[0051] Furthermore, the length of the water tank pipe 321 is longer than the space enclosed by the two sets of baffles 323;

[0052] In this preferred embodiment, the wastewater impacts the partition plates 326 between the baffles 323 within the filter box 31 due to its own impact force. The partition plates 326 rotate via rotating rings 322 on the water tank pipe 321. With the assistance of the filter screen 325, impurities in the wastewater are treated. The treated wastewater enters the water tank pipe 321 through the inlet 324. As the baffles 323 rotate, the impurities fall onto the waste plate 33 due to inertia and finally slide into the waste storage tank for further processing. The electric valve on the first drain pipe 34 is activated, and the liquid in the water tank pipe 321 is discharged into the wastewater treatment tank 351 through the first drain pipe 34. The wastewater passes through the pebble filter layer 352 in sequence. The quartz sand filter media layer 353, modified fiber ball layer 354, and activated alumina ball water purification filter media layer 355 are used for treatment. The treated circulating liquid enters the water storage tank 38 through the second drain pipe 36. With the assistance of the ceramic membrane body 37 in the water storage tank 38, suspended solids, colloids, macromolecular organic matter, and heavy metal ions are effectively intercepted, resulting in high filtration accuracy and ensuring that the water quality meets the discharge standards. Finally, the liquid is stored in the water storage tank 38 for recycling. With the assistance of the pressure pump on the water supply pipe 391, the pressurized liquid enters the high-pressure nozzle 393 on the support plate 392 through the water supply pipe 391. With the assistance of multiple sets of high-pressure nozzles 393, the filter screen 325 is cleaned to prevent clogging of the filter screen 325.

[0053] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, a shape measurement structure 4 is installed on the slope anti-slip structure 1 and is used to measure the deformation of the open-pit coal mine slope. The shape measurement structure 4 includes a support pipe 41. The support pipe 41 adjusts the position of the sealing box 42 by telescopic structure. An angle adjustment component 43 is installed inside the sealing box 42. An inSAR radar body 44 is installed on the upper side of the angle adjustment component 43. The angle adjustment component 43 includes a second motor box 431. The motor in the second motor box 431 drives the gear set 432 to rotate. The rotation of the gear set 432 drives the rotating rod 433 to rotate and adjust the angle of the inSAR radar body 44.

[0054] Among them, the motor in the second motor box 431 is a stepper motor, which is existing technology;

[0055] The inSAR radar body 44 calculates surface elevation or deformation information by analyzing the phase difference between two images. It acquires two complex images of the same area by repeatedly observing with two antennas or the same antenna. These two images must have sufficient coherence. After the two images are accurately registered, an interferogram is generated by calculating the phase difference to eliminate terrain phase and atmospheric interference. Finally, the surface elevation or deformation data is obtained by phase difference conversion. This process requires professional algorithm processing to improve accuracy. The inSAR radar body 44 is suitable for all-weather, large-area surface monitoring and can accurately measure deformation caused by disasters such as earthquakes and landslides. It has the advantages of being unaffected by weather and having high spatial resolution.

[0056] In the preferred embodiment, with the assistance of the hydraulic cylinder inside the support pipe 41, the hydraulic rod drives the sealing box 42 to adjust its height. With the assistance of the stepper motor inside the second motor box 431, the gear set 432 rotates. The rotation of the gear set 432 drives the rotating rod 433 to rotate, and the rotation of the rotating rod 433 drives the inSAR radar body 44 to adjust its angle. This allows for better real-time monitoring of the open-pit coal mine slope, providing early warning in the event of disasters such as landslides, and giving workers more time to evacuate.

[0057] Working principle: When using this multi-functional device for anti-slip and diversion of open-pit coal mine slopes, the external power supply is connected. The anti-slip structure 1 provides anti-slip and protection for the open-pit coal mine slope. The diversion structure 2 diverts water and prevents blockage. The wastewater recycling structure 3 ensures the quality of water recovery. The morphological measurement structure 4 monitors the entire slope in real time and provides timely warnings in the event of natural disasters.
