[0002] During the mining process, a large number of exposed slopes are formed due to excavation, disposal and other activities. These slopes are prone to soil erosion under the influence of natural factors such as rainfall, which not only damages the ecological environment, but may also cause geological disasters such as mud and rock flows and landslides, posing a threat to the safety of life and property in the surrounding areas. Therefore, real-time monitoring of soil erosion is necessary to facilitate the assessment of the soil erosion risk status of the profile.

[0003] A Chinese patent with the announcement number CN217111911U discloses a slope water and soil loss monitoring device, which includes a slope, a placement box and a touch display. The placement box is provided with a mounting groove, a weighing slot and a plurality of weighing sensors. The placement box is provided with an inclined plate connected to the outer surface of the slope. The bottom end of the inclined plate extends to the top of the weighing slot. The two sides of the weighing slot are respectively a baffle and a mounting plate. A push plate movably arranged between the baffle and the mounting plate is used to drive the baffle to rotate. A left drive mechanism is used to drive the push plate. The right drive mechanism is used for the horizontal movement of the plate, and a discharge trough is provided on one side of the mounting groove facing the baffle; when in use, the placement box is set at the bottom of the outer surface of the slope, so that the inclined plate is connected to the outer surface of the slope, and the mud and water on the outer surface of the slope flow into the weighing trough along the inclined plate, and the mud and water in the weighing trough are weighed through multiple weighing sensors, and the weighing results are displayed through the touch display; after weighing is completed, the left drive mechanism drives the baffle to rotate, so that one end of the baffle is rotated into the discharge trough, and the right drive mechanism drives the push plate to move horizontally to push the mud and water in the weighing trough along the baffle.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figures 1 to 8 As shown, a device for assessing the risk of water and soil loss on a slope in a mine remediation project according to an embodiment of the present invention comprises: a slope 1; a collecting trough 2, arranged at the bottom of the slope 1; two side plates 4, which are arranged on both sides of the slope 1, and the bottom ends of which are connected to the side walls of the collecting trough 2; a data acquisition unit, which is arranged in the collecting trough 2 and is used to collect data on water and soil loss on the slope; the data acquisition unit comprises a water collecting box 21, a soil collecting box 22, a first weighing sensor 23 and a second weighing sensor 24; the first weighing sensor 23 is arranged at the bottom of the collecting trough 2 The water collecting box 21 is arranged on the top of the first weighing sensor 23; the second weighing sensor 24 is arranged on the four corners of the top of the water collecting box 21, and the soil collecting box 22 is arranged on the top of the second weighing sensor 24; a plurality of filter holes 25 are provided at the bottom of the soil collecting box 22; a cleaning mechanism is provided above the soil collecting box 22, and the cleaning mechanism includes a rotating plate 35 and a scraper 36; a drainage mechanism is provided on one side of the water collecting box 21, and the drainage mechanism includes a water supply pipe 5, a water spray pipe 54 and a nozzle 55.

[0038] In the prior art, since the silt and rainwater flow into the weighing trough together for weighing, only the total weight can be weighed, and it is impossible to separate the water and silt therein and weigh the silt and rainwater separately, so it is impossible to accurately assess the risk of soil and water loss on the slope, and it is impossible to make accurate protective measures against soil and water loss. When the data acquisition unit provided by the present invention is in use, the silt and rainwater on the slope 1 flow to the collection trough 2 under the action of gravity. When the silt and rainwater pass through the soil collecting box 22, the silt is filtered in the soil collecting box 22, and the rainwater flows into the water collecting trough and is used to monitor the weight of the water in the water collecting box 21 through the first weighing sensor 23 for evaluating the precipitation situation. The second weighing sensor 24 is used to monitor the weight of the silt in the soil collecting box 22 for evaluating the silt loss situation.

[0039] During the flow of rainwater and sediment, the rotating plate 35 pushes the sediment in the soil collecting box 22 to one side to prevent the sediment from blocking the filter hole 25, causing the rainwater to be unable to flow downward and overflow; the scraper 36 scrapes the branches and grass roots on one side of the shielding fence 42 to one side to prevent blocking the flow of rainwater and sediment; the collected rainwater is reused for irrigation through the drainage mechanism.

[0040] like Figure 1 and Figure 4As shown, the water collecting box 21 is rotatably connected to a bidirectional ball screw 31 through a bearing; a first motor 3 is fixed to the side wall of the water collecting box 21, and the output shaft of the first motor 3 is fixed to one end of the bidirectional ball screw 31; two movable plates 33 are threadedly connected to the bidirectional ball screw 31, and the bottoms of the movable plates 33 are rotatably connected to rotating plates 35 through rotating shafts, and the bottoms of the rotating plates 35 are in contact with the bottom of the soil collecting box 22; a micro motor 34 is provided at one end of the rotating shaft; two guide rods 32 are fixed to the collecting trough 2, and the movable plates 33 are slidably connected to the two guide rods 32.

[0041] The bidirectional ball screw 31 provided in the present invention is used to adjust the position of the movable plate 33 when in use. When it rains, rainwater and sediment flow into the collection tank 2. By turning on the first motor 3, the output shaft of the first motor 3 drives the bidirectional ball screw 31 to rotate, and the bidirectional ball screw 31 drives the movable plate 33 to move in different directions. When the movable plate 33 moves, the movable plate 33 slides on the guide rod 32, and the guide rod 32 limits the movable plate 33 to move in the horizontal direction;

[0042] When the movable plate 33 moves to both sides during the movement, the mud and sand in the soil collecting box 22 are moved to one side to prevent the mud and sand from blocking the filter holes 25 and the rainwater from being filtered and flowing down. At this time, the rotating plate 35 is in contact with the bottom of the soil collecting box 22; when the movable plate 33 moves toward the middle, in order to prevent the rotating plate 35 from scraping the mud and sand at the bottom of the soil collecting box 22 to the center, it is necessary to drive the micro motor 34, and the rotating plate 35 is driven by the micro motor 34 to rotate and separate from the bottom of the soil collecting box 22 until the two movable plates 33 move together, thereby realizing the function of thoroughly cleaning the bottom of the soil collecting box 22 and facilitating the pushing out of the mud and sand for unloading.

[0043] like Figure 2 and Figure 7 As shown, the tops of the side panels 4 are fixedly connected to first pillars 41 , and the tops of the two first pillars 41 are fixedly connected to shielding fences 42 ; the side walls of the movable plate 33 are fixedly connected to scrapers 36 , and the scrapers 36 slide in the shielding fences 42 .

[0044] When the scraper 36 provided by the present invention is in use, branches and grass roots may flow down during rainfall and accumulate under the rain, affecting the flow of rainwater and sediment, resulting in inaccurate monitoring data. Therefore, a shielding fence 42 is provided to block branches and grass roots, and a scraper 36 is provided to scrape the branches and grass roots to one side without affecting the flow of rainwater.

[0045] like Figure 1 and Figure 6As shown, both ends of the collecting trough 2 are rotatably connected to a reciprocating screw 61 through bearings, and a sealing plate 6 is threadedly connected to the reciprocating screw 61. Two vertical rods 62 are fixed to the collecting trough 2, and the two vertical rods 62 are respectively arranged on both sides of the reciprocating screw 61, and both ends of the sealing plate 6 are slidably connected to the vertical rods 62; the tops of both ends of the collecting trough 2 are fixed with a second motor 63, and the output shafts of the second motor 63 are respectively fixed to the tops of the reciprocating screw 61.

[0046] The sealing plate 6 provided by the present invention is used to seal the soil collecting box 22 when in use. After the monitoring is completed, the mud and sand in the soil collecting box 22 need to be pushed out and unloaded. By turning on the second motor 63, the reciprocating screw 61 is driven to rotate by the output shaft of the second motor 63, and the sealing plate 6 is driven to move by the reciprocating screw 61. When the sealing plate 6 moves to the bottom, it is used to seal the soil collecting box 22. When the sealing plate 6 moves to the top, it is convenient for unloading of mud and sand. The mud and sand unloading requires the mud and sand in the soil collecting box 22 to be pushed out by the rotating plate 35.

[0047] like Figure 1 and Figure 2 As shown, two second pillars 45 are fixed to the top of the collecting tank 2, and an inclined plate 43 is fixed to the top of the two second pillars 45. One end of the inclined plate 43 is fixed to the top of the first pillar 41, and a photovoltaic panel 44 is fixed to the top of the inclined plate 43.

[0048] When in use, the photovoltaic panel 44 provided by the present invention is used to absorb solar energy, convert it into electrical energy and store the energy, which is convenient for powering the motor and the electric push rod 58. By setting the photovoltaic panel 44 and the inclined plate 43, it is convenient to shield the collection trough 2 to prevent rainwater from falling directly and affecting the monitoring data of soil erosion.

[0049] like Figure 2 、 Figure 5 and Figure 6 As shown, the water collecting box 21 is connected and fixedly connected with a water supply pipe 5, one end of the water supply pipe 5 passes through the collecting tank 2, and is installed with a water pump 53, and the water pump 53 is fixedly connected to the side wall of the water collecting tank through a fixing plate 52; one end of the water supply pipe 5 is rotatably connected to a rotating tube, one end of the rotating tube is fixedly connected to a water spraying pipe 54, and the water spraying pipe 54 is provided with a plurality of nozzles 55; the rotating tube is set as a hollow tube; a gear 56 is fixedly connected to the outer wall of the rotating tube; an electric push rod 58 is fixedly connected to the side wall of the inclined plate 43, and the output end of the electric push rod 58 is fixedly connected to a connecting plate 59, and a rack 57 is fixedly connected to the side wall of the connecting plate 59, and the rack 57 is meshed with the gear 56.

[0050] When the gear 56 and rack 57 provided by the present invention are in use and irrigation is required, the water pump 53 is turned on, and the water in the water collecting tank 21 is output to the water spraying pipe 54 through the water supply pipe 5, and the water in the water spraying pipe 54 is sprayed on the planting area of the slope 1 through the nozzle 55; during the spraying process, the electric push rod 58 is turned on, and the connecting plate 59 is driven to move by the output end of the electric push rod 58, and the rack 57 is driven to move by the connecting plate 59, and the gear 56 is driven to rotate by the rack 57, and the rotating pipe is driven to rotate by the gear 56, and the water spraying pipe 54 is driven to rotate by the rotating pipe, and the nozzle 55 is driven to rotate by the water spraying pipe 54, so as to expand the irrigated area.

[0051] like Figure 6 As shown, a sliding opening is provided on the rack 57 , and two limit blocks 510 are fixedly connected to the side wall of the inclined plate 43 , and the limit blocks 510 are both slidably connected in the sliding opening.

[0052] When the limit block 510 provided by the present invention is in use, the rack 57 is in motion, and the limit block 510 slides in the sliding opening, and the limit block 510 limits the rack 57 from moving in the horizontal direction.

[0053] like Figure 3 As shown, two fixing blocks 51 are fixed to the bottom of the inclined plate 43 , and the water pipe 5 is connected through the two fixing blocks 51 .

[0054] The fixing block 51 provided by the present invention is used to fix the water pipe 5 when in use, so as to prevent the water pipe 5 from getting tangled during the mechanical movement, thereby affecting the progress of the mechanical movement.

[0055] Working principle: The silt and rainwater on the slope 1 flow to the collection trough 2 under the action of gravity. When the silt and rainwater pass through the soil collecting box 22, the silt is filtered in the soil collecting box 22, and the rainwater flows into the water collecting trough. The first weighing sensor 23 is used to monitor the weight of the water in the water collecting box 21 for evaluating the precipitation situation; the second weighing sensor 24 is used to monitor the weight of the silt in the soil collecting box 22 for evaluating the silt loss situation; during the flow of rainwater and silt, the silt in the soil collecting box 22 is pushed to one side by the rotating plate 35 to prevent the silt from blocking the filter hole 25, resulting in the rainwater being unable to flow downward and overflowing; the branches and grass roots on one side of the shielding fence 42 are scraped to one side by the scraper 36 to prevent blocking the flow of rainwater and silt; the collected rainwater is reused for irrigation through the drainage mechanism;

[0056] When it rains, rainwater and sediment flow into the collecting trough 2. By turning on the first motor 3, the output shaft of the first motor 3 drives the bidirectional ball screw 31 to rotate, and the bidirectional ball screw 31 drives the movable plate 33 to move in different directions. When the movable plate 33 moves, the movable plate 33 slides on the guide rod 32, and the guide rod 32 limits the movable plate 33 to move in the horizontal direction. When the movable plate 33 moves to both sides, the sediment in the soil collecting box 22 is moved to one side to prevent the sediment from blocking the filter hole 25, and the rainwater cannot flow. The filter flow is filtered down, and at this time the rotating plate 35 contacts the bottom of the soil collecting box 22; when the moving plate 33 moves toward the middle, in order to prevent the rotating plate 35 from scraping the mud and sand at the bottom of the soil collecting box 22 toward the center, it is necessary to drive the micro motor 34, and the micro motor 34 drives the rotating plate 35 to rotate and separate from the bottom of the soil collecting box 22 until the two moving plates 33 move together, thereby achieving the function of thoroughly cleaning the bottom of the soil collecting box 22 and facilitating the pushing out of the mud and sand for unloading; the moving plate 33 drives the scraper 36 to move, scraping the branches and grass roots to one side without affecting the flow of rainwater;

[0057] After the monitoring is completed, the sediment in the soil collecting box 22 needs to be pushed out for unloading. By turning on the second motor 63, the reciprocating screw 61 is driven to rotate by the output shaft of the second motor 63, and the blocking plate 6 is driven to move by the reciprocating screw 61. When the blocking plate 6 moves to the bottom, it is used to block the soil collecting box 22. When the blocking plate 6 moves to the top, it is convenient for unloading the sediment. The sediment unloading needs to push the sediment in the soil collecting box 22 out by rotating the plate 35.

[0058] When irrigation is needed, the water pump 53 is turned on, and the water in the water collecting tank 21 is output to the water spraying pipe 54 through the water supply pipe 5, and the water in the water spraying pipe 54 is sprayed on the planting area of the slope 1 through the nozzle 55; during the spraying process, the electric push rod 58 is turned on, and the output end of the electric push rod 58 drives the connecting plate 59 to move, and the connecting plate 59 drives the rack 57 to move, and the rack 57 drives the gear 56 to rotate, and the gear 56 drives the rotating pipe to rotate, and the rotating pipe drives the water spraying pipe 54 to rotate, and the water spraying pipe 54 drives the nozzle 55 to rotate, thereby expanding the irrigated area.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention.
