Description

Technical Field

[0001] This application relates to the technical field of mine ecological governance, and particularly relates to an ecological restoration grid for open-pit mine slopes. Background Art

[0002] With the continuous deepening of mine exploitation, the ecological environment of the slopes of open-pit mines will be severely damaged. Rainwater scouring and soil and rock landslides bring serious pollution and safety hazards to the surrounding environment. Therefore, it is necessary to repair the slope ecology of open-pit mines.

[0003] Currently, the main method for ecological restoration of open-pit mine slopes is to build concrete grids on the slopes, and then sow grass seeds in multiple grid areas surrounded by the concrete grids. The concrete grids are used to fix the soil and rock on the slopes, and the method of planting grass for greening is used to prevent soil and water scouring on the slopes, so as to slowly repair the ecological environment of the slopes.

[0004] In the above solution, before the grass seeds grow, the soil in each grid area will be exposed to wind and rain. In rainy or windy weather, the soil in the grid area is likely to be washed away by rain or wind, which is not conducive to the initial repair of slope ecology. Summary of the Invention

An elastic rope is connected to the side of the cleaning brush block away from the pull rope. The other end of the elastic rope is connected to the floating block. And the connection position of the elastic rope and the floating block is located on the side of the floating block away from the fixed pulley. When the fan is blown by the wind and rotates, the fan drives the transmission shaft to rotate. The transmission shaft can wind the pull rope on itself. The pull rope first pulls the cleaning brush block to slide to clean the filter screen. After the cleaning brush block abuts against the fixed pulley, the pull rope then pulls the floating block to slide towards the installation hole.

The shielding mechanism includes a rain shielding component and a wind-driven component. Among them, the floating block can drive the rain shielding rod to slide under the driving force of the buoyancy of rainwater. The rain shielding rod can drive the shielding cloth to unfold under the guiding action of the rain shielding shaft. The shielding cloth in the unfolded state can block the rainwater from scouring the soil in the grid area. The floating block can also slide under the driving force formed by the rotation of the wind-driven fan to drive the rain shielding rod to unfold the shielding cloth. Thus, in rainy or windy weather, the shielding cloth can be automatically unfolded to protect the soil in the grid area from being blown and washed by the wind and rain, and further protect the slope from soil loss in the initial stage of ecological restoration.

[0025] 2. An ecological restoration grid for open-pit mine slopes in the present application further includes a filter screen and a cleaning component.

[0034] The following further elaborates on this application in conjunction with the attached Figures 1-6 drawings to provide a more detailed description.

[0035] An embodiment of this application discloses an ecological restoration grid for open-pit mine slopes. Referring to Figure 1 , an ecological restoration grid for open-pit mine slopes includes a concrete grid 1 and a shielding mechanism 2. The concrete grid 1 is poured on the slope and encloses multiple grid areas 11 on the slope. There are multiple shielding mechanisms 2, and they are respectively arranged in the grid areas 11 one by one. The shielding mechanism 2 includes a rain shielding assembly 3 and a wind driving assembly 4.

[0036] Referring to Figure 1 , Figure 2 and Figure 3 , the rain shielding assembly 3 includes a rain shielding box 31, a connecting rope 32, a connecting part 33, a shielding cloth 34, a floating block 35, a folding part 36 and a rain discharging part 37.

[0037] Referring to Figure 1 , the rain shielding box 31 is arranged at the center position of the grid area 11. There are multiple connecting ropes 32 arranged around the rain shielding box 31, and one end of each connecting rope 32 is fixedly connected to the outer wall of the rain shielding box 31. There are multiple connecting parts 33, and they correspond to the connecting ropes 32 one by one. The connecting parts 33 are respectively connected to the connecting ropes 32 and the concrete grid 1. The connecting parts 33 are used to detachably tension the connecting ropes 32 to the concrete grid 1, so that the rain shielding box 31 can be conveniently recycled.

[0038] Referring to Figure 1 , Figure 2 and Figure 3, an installation hole 311 is provided at the center position of the end of the rain shield box 31 away from the slope, and a plurality of folding holes 312 are provided at one end of the rain shield box 31 close to the installation hole 311. The plurality of folding holes 312 are arranged around the installation hole 311, and the folding holes 312 communicate with the installation hole 311. The shielding cloth 34 is inserted through the installation hole 311 in a posture where the edges converge, and the central part of the shielding cloth 34 passes through the installation hole 311. Part of the cloth is folded and inserted in each folding hole 312 of the shielding cloth 34. A rain collecting hole 341 is provided at the center position of the shielding cloth 34, and the rain collecting hole 341 is used to allow rainwater to flow into the rain shield box 31.

[0039] Refer to Figure 2 and Figure 3 , a floating block 35 is slidably arranged in the rain shield box 31. The side wall of the floating block 35 is attached to the inner side wall of the rain shield box 31. The density of the floating block 35 is less than the density of rainwater. The floating block 35 can slide towards the installation hole 311 under the buoyancy of rainwater. A rain inlet hole 351 is provided at the center position of the floating block 35, and the rain inlet hole 351 penetrates the floating block 35. The folding part 36 is respectively connected to the floating block 35 and the shielding cloth 34. The folding part 36 is used to drive the shielding cloth 34 to unfold into a conical shape when the floating block 35 slides towards the installation hole 311, and the folding part 36 is used to drive the shielding cloth 34 to fold when the floating block 35 slides away from the installation hole 311.

[0040] Refer to Figure 1 , Figure 2 and Figure 3 , a rain discharging part 37 is connected to the rain shield box 31 and is used to discharge the rainwater in the rain shield box 31. The rain discharging flow rate of the rain discharging part 37 is lower than the rain inlet flow rate of the rain inlet hole 351; when the rainfall is lower than the preset rainfall amount, the rain discharging part 37 can discharge the rainwater entering the rain shield box 31, and at this time the shielding cloth 34 maintains a folded state; when the rainfall is not lower than the preset rainfall amount, the rainwater can accumulate in the rain shield box 31 to drive the floating block 35 to slide towards the installation hole 311 through buoyancy.

[0041] Refer to Figure 2 and Figure 3 , the wind driving assembly 4 includes a fan 41 and a transmission part 42. The fan 41 is arranged outside the rain shield box 31. The transmission part 42 is respectively connected to the fan 41 and the floating block 35. The transmission part 42 is used to drive the floating block 35 to slide towards the installation hole 311 when the fan 41 is blown by the wind and rotates, so that the shielding cloth 34 unfolds into a conical shape.

[0042] During use, when it rains on the slope, when the rainfall is lower than the preset rainfall amount, the rainwater entering the rain shield box 31 from the rain collecting hole 341 of the shielding cloth 34 can be discharged by the rain discharging part 37, making it difficult for the floating block 35 to slide towards the installation hole 311 under the buoyancy, and the shielding cloth 34 can be in a folded state, so that the grass seeds in the grid area 11 can receive the nourishment of rainwater.

[0043] When the rainfall is not less than the preset rainfall, rainwater flows from the rain-collecting holes 341 of the shielding cloth 34 through the rain inlet holes 351 of the floating block 35 into one end of the rainshield box 31 close to the slope. Since the rain-draining flow rate of the rain-draining part 37 is lower than the rain inlet flow rate of the rain inlet holes 351, the amount of rainwater flowing into the rainshield box 31 will be greater than the amount of rainwater discharged. Therefore, during heavy rainfall, rainwater can be accumulated in the rainshield box 31, and the accumulated rainwater can drive the floating block 35 to slide towards the mounting hole 311. The floating block 35 unfolds the shielding cloth 34 through the folding part 36. On the one hand, the shielding cloth 34 makes it difficult for rainwater to wash the soil in the grid area 11. On the other hand, the shielding cloth 34 can collect rainwater into the rainshield box 31, so that the rainwater is discharged centrally through the rain-draining part 37, thereby making the soil in the grid area 11 not easily washed by rainwater and enabling the grass seeds to receive the nourishment of rainwater.

[0044] When the slope is windy, the wind can drive the fan 41 to rotate. The fan 41 can drive the floating block 35 to slide towards the mounting hole 311 through the transmission part 42. The floating block 35 can unfold the shielding cloth 34 through the folding part 36. The shielding cloth 34 blocks the wind from directly blowing on the soil in the grid area 11, so that the soil is not easily blown away by the wind.

[0045] In the weather of strong wind and heavy rain, the shielding cloth 34 can be automatically unfolded to block the direct action of wind and rain on the soil, so that the soil in the grid area 11 is not easily lost due to rainwater or wind, which is beneficial to the initial repair of the slope ecology.

[0046] The rainshield box 31 is detachably connected to the concrete grid 1 through the connecting rope 32. On the one hand, it makes the soil and stones in the grid area 11 not easily slide. On the other hand, in the later stage of the repair when the grass seeds grow, the rainshield box 31 can be disassembled and recycled, so that the shielding mechanism 2 can be recycled.

[0047] Specifically, referring to Figure 3 the folding part 36 includes a rainshield shaft 361 and a rainshield rod 362. [[ID=!6]]

[0048] Referring to Figure 2 and Figure 3There are multiple rain shield shafts 361 and rain shield rods 362, and they correspond one to one. The rain shield shafts 361 are arranged in the folding holes 312 one by one, and the rain shield shafts 361 are arranged away from the mounting holes 311. The rain shield shafts 361 are fixedly connected to the rain shield box 31. One end of the rain shield rod 362 is hinged on the side of the floating block 35 near the mounting hole 311, and the hinge between the rain shield rod 362 and the floating block 35 is set near the center of the floating block 35. The rain shield rod 362 slides through the folding hole 312. A sliding hole 363 is provided on the rain shield rod 362, and the rain shield shaft 361 is slidably set in the sliding hole 363. The rain shield rod 362 is fixedly connected to the shield cloth 34. When the floating block 35 slides toward the mounting hole 311, the rain shield rod 362 drives the shield cloth 34 to unfold under the guidance of the rain shield shaft 361. When the floating block 35 slides away from the mounting hole 311, the rain shield rod 362 drives the shield cloth 34 to fold under the guidance of the rain shield shaft 361.

[0049] When the float 35 slides toward the mounting hole 311, the float 35 drives the rain shield rod 362 to gradually slide out of the rain shield box 31. Since the rain shield shaft 361 is arranged away from the mounting hole 311, and the hinge between the rain shield rod 362 and the float 35 is arranged close to the center of the float 35, the end of the rain shield rod 362 away from the float 35 can gradually swing in the direction away from the mounting hole 311 under the guidance of the rain shield shaft 361, so that the shielding cloth 34 can gradually unfold during the swinging process of the rain shield rod 362.

[0050] Specifically, refer to Figure 1 The rain discharge part 37 includes a rain discharge pipe 371 and a drainage pipe 372.

[0051] One end of the rainwater drainage pipe 371 is connected to the end of the rain shield box 31 near the slope, and the other end is connected to the side wall of the drainage pipe 372. The drainage pipe 372 is set at the bottom end of the grid area 11 and is detachably connected to the concrete grid 1. Multiple collection pipes 12 are detachably connected to the concrete grid 1. All collection pipes 12 are arranged obliquely along the slope, with a grid area 11 separating adjacent collection pipes 12 in the horizontal direction. The two ends of each drainage pipe 372 are slidably installed on the two adjacent collection pipes 12, and the drainage pipe 372 is connected to the collection pipe 12. The collection pipe 12 is used to collect rainwater into the canal at the bottom of the slope. The canal at the bottom of the slope is not shown in the figure.

[0052] When draining rainwater, the rain drain pipe 371 can divert the rainwater in the rain shield box 31 into the drainage pipe 372, and the drainage pipe 372 can drain the rainwater into the collection pipe 12. The collection pipe 12 can make the rainwater converge into the water channel on the slope, so that the rainwater is easy to collect and discharge.

[0053] In particular, refer to Figure 1 、 Figure 4 and Figure 5, the concrete grid 1 respectively has the same detachable connection structure with the drainage pipe 372 and the collection pipe 12. The detachable connection structure includes an iron nail 3721 and a wire 3722. The tip of the iron nail 3721 is buried in the concrete grid 1, and the wire 3722 binds the drainage pipe 372 or the collection pipe 12 to the iron nail 3721, so that both the drainage pipe 372 and the collection pipe 12 are convenient to be detached from the concrete grid 1.

[0054] Specifically, referring to Figure 4 , the connecting part 33 includes a connecting rod 331, a connecting sliding rod 332 and a connecting sleeve 333.

[0055] One end of the connecting rod 331 is buried in the concrete grid 1. There are two connecting sliding rods 332 arranged around the connecting rod 331. The connecting sliding rods 332 are fixedly connected to the side wall of the connecting rod 331 exposed outside the concrete grid 1. The two connecting sliding rods 332 are symmetrically arranged, and the connecting sliding rods 332 are in the shape of circular rods.

[0056] One end of the connecting sleeve 333 is sealed and fixedly connected to the connecting rope 32. The connecting sleeve 333 is sleeved on the connecting rod 331. The inner wall of the connecting sleeve 333 fits on the side wall of the connecting rod 331. There are two connecting spiral holes 3331 opened on the side wall of the connecting sleeve 333. The connecting spiral holes 3331 correspond to the connecting sliding rods 332 one by one. The connecting sliding rods 332 are slidably arranged in the connecting spiral holes 3331. By rotating the connecting sleeve 333, the connecting rope 32 can be tightened, and the connecting rope 32 is connected to the concrete grid 1.

[0057] When installing the rainshield box 31, the connecting sleeve 333 is sleeved on the connecting rod 331, and then the connecting sleeve 333 is rotated, so that the connecting sliding rod 332 slides in the corresponding connecting spiral hole 3331. Through the pressing force of the connecting sliding rod 332 on the hole wall of the connecting spiral hole 3331, the connecting rope 32 can be tensioned, and the connecting rope 32 can be connected to the concrete grid 1, so that the rainshield box 31 is not only convenient to be installed on the concrete grid 1, but also convenient to be detached from the concrete grid 1.

[0058] Furthermore, referring to Figure 4 , in order to make the connection between the connecting sleeve 333 and the connecting rod 331 more stable, a locking nut 334 is threadedly sleeved on the connecting sliding rod 332. When the locking nut 334 is screwed to abut against the connecting sleeve 333, the locking nut 334 can fix the connecting rod 331 and the connecting sleeve 333. Through the locking nut 334, the connecting sleeve 333 can be extruded on the connecting rod 331, increasing the friction force between the connecting sleeve 333 and the connecting rod 331, so that the connecting rod 331 and the connecting sleeve 333 are not easily separated.

[0059] Referring to Figure 3, in order to prevent the rainwater drain pipe 371 from being easily blocked, a filter screen 5 is provided at the rain inlet hole 351. The filter screen 5 is fixedly connected to the floating block 35. The rainwater is filtered through the filter screen 5, so that impurities mixed in the rainwater are not easily introduced into the rainwater drain pipe 371, and the rainwater drain pipe 371 is not easily blocked.

[0060] Further, referring to Figure 2 and Figure 3 , in order to facilitate the cleaning of the filter screen 5, the filter screen 5 is located at one end of the rain inlet hole 351 close to the mounting hole 311. A cleaning assembly 6 is provided on the floating block 35. The cleaning assembly 6 includes a cleaning brush block 61. The cleaning brush block 61 is slidably disposed on one side of the floating block 35 close to the mounting hole 311. The sliding track of the cleaning brush block 61 passes through the filter screen 5. When the cleaning brush block 61 is slid, the cleaning brush block 61 can clean the filter screen 5.

[0061] Since the sliding track of the cleaning brush block 61 passes through the filter screen 5, when the cleaning brush block 61 is slid, the cleaning brush block 61 can clean the filter screen 5 to remove the impurities intercepted on the filter screen 5, so that the filter screen 5 can restore its filtering ability.

[0062] Specifically, referring to Figure 3 , the transmission part 42 includes a pull rope 421 and a transmission shaft 422.

[0063] Referring to Figure 3 and Figure 6 , one end of the pull rope 421 is fixedly connected to the cleaning brush block 61. The pull rope 421 is arranged on a fixed pulley 352 provided on the floating block 35. The fixed pulley 352 changes the pulling direction of the pull rope 421. The other end of the pull rope 421 slides out of the rain shield 31 and is connected to the transmission shaft 422. The transmission shaft 422 is rotatably connected to the outer wall of the rain shield 31. The fan 41 is connected to the transmission shaft 422.

[0064] Referring to Figure 2 and Figure 3 , an elastic rope 62 is fixedly connected to the side of the cleaning brush block 61 away from the pull rope 421. The other end of the elastic rope 62 is fixedly connected to the floating block 35, and the connection position of the elastic rope 62 and the floating block 35 is located on the side of the floating block 35 away from the fixed pulley 352. When the fan 41 is driven to rotate by the wind, the fan 41 drives the transmission shaft 422 to rotate. The transmission shaft 422 can wind the pull rope 421 around itself. The pull rope 421 first pulls the cleaning brush block 61 to slide to clean the filter screen 5. After the cleaning brush block 61 abuts against the fixed pulley 352, the pull rope 421 then pulls the floating block 35 to slide towards the mounting hole 311. When the wind stops blowing the fan 41, the elastic rope 62 can drive the cleaning brush block 61 to reset by its elasticity.

[0065] When the wind blows, the wind drives the fan 41 to rotate. The fan 41 drives the transmission shaft 422 to rotate. The transmission shaft 422 winds the pull rope 421 around itself. The pull rope 421 first drives the cleaning brush block 61 to slide to clean the filter net 5, and at the same time stores elastic force in the elastic rope 62. After the cleaning brush block 61 abuts against the fixed pulley 352, the pull rope 421 then drives the floating block 35 to slide towards the mounting hole 311, so that the shielding cloth 34 unfolds. Thus, the wind-driven fan 41 can unfold the shielding cloth 34 and can clean the filter net 5; when the wind stops blowing, the elastic rope 62 can drive the cleaning brush block 61 to slide in the reverse direction through the elastic force, so that the cleaning brush block 61 cleans the filter net 5 again and resets the cleaning brush block 61.

[0066] Further, referring to Figure 6 , in order to make the fan 41 easy to be driven by the wind to rotate, the transmission shaft 422 includes a first rotating shaft 423 and a second rotating shaft 424.

[0067] Referring to Figure 1 , Figure 3 and Figure 6 , the first rotating shaft 423 is rotatably connected to the outer wall of the rain shield box 31. The second rotating shaft 424 is arranged at one end of the first rotating shaft 423 away from the rain shield box 31. The second rotating shaft 424 is in bevel gear transmission connection with the first rotating shaft 423. The fan 41 is fixedly connected to one end of the second rotating shaft 424 away from the first rotating shaft 423. The fan 41 protrudes out of the concrete grille 1. A transmission pipe 425 is sleeved on the first rotating shaft 423 and the second rotating shaft 424 together. The transmission pipe 425 is fixedly connected to the outer wall of the rain shield box 31. Both the first rotating shaft 423 and the second rotating shaft 424 are rotatably connected to the transmission pipe 425. The pull rope 421 slidably passes through the transmission pipe 425 and is fixedly connected to the first rotating shaft 423.

[0068] Through the first rotating shaft 423 and the second rotating shaft 424, the fan 41 can protrude out of the concrete grille 1, making the fan 41 more easily driven by the wind; when the wind drives the fan 41 to rotate, the fan 41 can drive the second rotating shaft 424 to rotate. The second rotating shaft 424 can drive the first rotating shaft 423 to rotate through bevel gear transmission. The first rotating shaft 423 can wind the pull rope 421 around itself, so that the fan 41 is more easily driven by the wind to make the floating block 35 slide towards the mounting hole 311.

[0069] Referring to Figure 3 , in order to make the floating block 35 easy to reset stably, a first magnetic ring 353 is fixedly embedded on one side of the floating block 35 close to the mounting hole 311. A second magnetic ring 313 is fixedly connected to one end of the rain shield box 31 where the mounting hole 311 is opened. The polarities of the mutually approaching sides of the first magnetic ring 353 and the second magnetic ring 313 are the same.

[0070] When the wind and rain stop, the magnetic thrust between the first magnetic ring 353 and the second magnetic ring 313 can assist the floating block 35 to slide towards the slope, so that the shielding cloth 34 can be folded, enabling the floating block 35 to be stably reset under the combined action of gravity and magnetic thrust.

[0071] Specifically, the magnetic thrust between the first magnetic ring 353 and the second magnetic ring 313 only plays an auxiliary role. Under the action of the magnetic thrust between the first magnetic ring 353 and the second magnetic ring 313, the floating block 35 can still slide under the buoyancy of rainwater.

[0072] The implementation principle of an ecological restoration grid for an open-pit mine slope in an embodiment of the present application is as follows: During use, the floating block 35 can drive the rainshield rod 362 to unfold the shielding cloth 34 under the buoyancy of rainwater, and the floating block 35 can also drive the rainshield rod 362 to unfold the shielding cloth 34 under the action of the driving force formed by the wind driving the fan 41 to rotate, enabling the shielding cloth 34 to automatically unfold in windy or heavy rain weather. The unfolded shielding cloth 34 can protect the soil in the grid area 11, so that the slope ecology is not easily caused by soil erosion due to wind and rain during the initial stage of restoration.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
