Description

Technical Field

[0001] The invention relates to the technical field of environmental governance, and in particular to a device for preventing soil and water loss in the Loess Plateau. Background Art

[0002] Due to long-term over-cultivation, over-cutting and over-grazing, the sloping cultivated land in the Loess Plateau has suffered from serious soil and water loss, ranging from gentle slopes of 3° to 5° to steep slopes of more than 25°. On average, 1 cm of soil is eroded every year, and the nutrients lost far exceed the annual fertilizer input, making it difficult to accumulate organic matter in the soil and improve land productivity. Now, by trimming the loess slopes into stepped terraces, the ground slope and runoff coefficient are changed, the slope length is shortened, and it has a strong soil and water conservation effect, which is a fundamental measure for the management of sloping cultivated land in the Loess Plateau. However, in practice, factors such as the flatness of horizontal terraces, the height and firmness of field ridges will affect the role of soil and water conservation. The existing ecological slope protection has less slope vegetation and weak soil and water retention capacity, resulting in weak resistance to rainwater erosion, and weak slope anti-seepage capacity. The infiltrated water is not easy to discharge, resulting in slope collapse, which in turn causes safety accidents.

[0003] In order to prevent soil erosion, it is often necessary to use soil erosion prevention devices to protect the soil and water. However, the current soil erosion prevention devices cannot solve the drainage problem, resulting in the accumulation of water being able to be drained only from the top of the prevention frame during the flow, and then the mud in the water will also be lost with the water flow, resulting in poor soil erosion prevention effect of the prevention device, thus affecting the use of the prevention device.

[0004] Therefore, we made improvements and proposed a soil and water loss protection device for the Loess Plateau. Summary of the invention

[0010] As a further solution of the present invention, the intercepting mechanism includes a water collecting box, which is C-shaped. The bottom end of the water collecting box is connected to a third hinge, which is hinged to the first hinge. A plurality of water screening holes are opened on the body of the water collecting box.

[0011] As a further solution of the present invention, the power mechanism includes a first electric push rod, the upper end of which is connected to the side of the intercepting mechanism, the bottom end of which is connected to the rear of the upper end surface of the sliding assembly, and a second electric push rod is connected in the middle of the first electric push rod, and the bottom end of the second electric push rod is connected to the front of the upper end surface of the sliding assembly.

[0012] As a further scheme of the present invention, the water holding mechanism includes a water bucket, both ends of the water bucket are equipped with hanging ears, the hanging ears are rotatably connected to the rope, the rope includes a steel rope and a control box, the control box is fixedly installed on the sliding assembly, one end of the steel rope is fixedly connected to the hanging ear, the other end of the steel rope is passed around the first hanging ring and fixedly connected to the second hanging ring, the end of the steel rope is fixedly installed with a connecting plate, the connecting plate is fixedly connected with a spring push rod, the end of the spring push rod is welded to the cross bar on one side of the first hanging ring, the spring push rod is electrically connected to the control box, a pressure switch is installed on the back of the control box, the bottom end of the water bucket is hinged with a connecting frame, the connecting frame is slidably installed inside the slide slot, and the upper end surface of the connecting frame is connected to the top of the slide slot with a spring.

[0014] The invention provides a device for preventing soil and water loss in the Loess Plateau, which has the following beneficial effects:

[0015] 1. The sliding assembly is installed on the fixed rail, and the shoveling assembly is installed on the sliding assembly, as well as an interception mechanism which is hinged with the shoveling assembly and can be driven to flip by a power mechanism, so that the shoveling assembly and the interception mechanism are intercepted at the edge of the field ridge of the terrace slope, and the muddy water containing silt produced by rainwater erosion is filtered, and the silt is retained in the interception mechanism, while the water flows downward from the interception mechanism, and the sliding assembly is controlled by the water holding mechanism to slide along the cross bar with the shoveling assembly and the interception mechanism. While sliding, the power mechanism drives the interception mechanism to flip along the third hinge, pour out the lining and silt inside the water collecting box, and evenly pave the surface of the terrace slope through the shoveling assembly to repair the terrace slope, ensure the soil stock on the terrace slope and the overall inclination gradient of the terrace slope, thereby strengthening the soil and water conservation of the Loess Plateau.

[0016] 2. By installing the liner inside the interception mechanism, the muddy water is filtered through pores with a smaller filtration coefficient than the water sieve holes, the silt is effectively intercepted to prevent soil erosion. When the interception mechanism is turned over, the liner can be poured out of the interception mechanism and the silt is taken out at one time, thereby avoiding the silt adhering to the inner wall of the interception mechanism and being difficult to pour out, thereby improving the convenience of using the device.

[0017] 3. The water-containing mechanism is installed by sliding on the column, and the upper end of the water-containing mechanism is connected to the rope. The water-containing mechanism receives a part of the leaked water from the intercepting mechanism. When the water inside the water-containing mechanism is full, the weight of the water-containing mechanism and the accumulated water as a whole exceeds the elasticity of the spring. When the water bucket slides down along the column to the bottom of the column as a whole, the water bucket flips over to pour out the accumulated water, and the water bucket rebounds to the upper end of the column. In the process of the water-containing mechanism falling, the mud and sand inside the intercepting mechanism are cleared and processed according to the cleaning action and emptying frequency of the accumulated water inside the water-containing mechanism, so as to improve the self-cleaning effect of the device.

A slide groove 23 is provided in front of the cross bar 21. A first hanging ring 25 is installed at the tail end of the cross bar 21. The ground spikes 24 at the bottom of the cross bar 21 fix the fixed rail 2 as a whole to prevent the device from loosening and shaking in waterlogged soil and ensure the stability of the device. The setting of the column 22 and the slide groove 23 can increase the stability of the device to prevent the interception mechanism 6 and the shovel assembly 5 from tipping over when they are located at the edge of the ladder slope. Secondly, the water holding mechanism 9 can be installed to facilitate the operation of the water holding mechanism 9.

[0033] The sliding assembly 3 includes a sliding platform 31, which is buckled on the outside of the cross bar 21, and a second hanging ring 32 is installed at one end of the sliding platform 31, and a bogie 33 is installed at the other end of the sliding platform 31. The sliding platform 31 connects the support frame 4, the shovel assembly 5 and the interception mechanism 6, so that the shovel assembly 5 and the interception mechanism 6 can be easily separated on the step slope to prevent mud and water from flowing out and causing soil erosion, and can also repair the soil layer on the step slope to avoid erosion of the soil layer thickness.

[0034] The shovel assembly 5 includes a shovel plate 51, which is an arc-shaped shovel with one end upturned, and a first hinge 52 is installed at the upper end of the shovel plate 51, and the first hinge 52 is connected to the interception mechanism 6. A second hinge 53 is installed in the middle of the shovel plate 51, and the second hinge 53 is movably installed with the support frame 4. The tip of the shovel plate 51 is close to the surface of the terraced slope soil layer, so that when rainwater scours, the muddy water flows along the shovel assembly 5 into the interception mechanism 6, avoiding the slope edge of the terraced slope from being washed away by rainwater, ensuring the soil consolidation and water conservation function of the terraced slope, and the shovel plate 51 can evenly spread the mud and sand dumped from the interception mechanism 6 on the soil layer surface when reversed, ensuring the flatness of the terraced slope.

[0035] The interception mechanism 6 includes a water collecting box 61, which is C-shaped. The bottom end of the water collecting box 61 is connected to a third hinge 62, and the third hinge 62 is hinged to the first hinge 52. A plurality of water screening holes 63 are provided on the body of the water collecting box 61. The curved shape of the water collecting box 61 can intercept muddy water, increase the edge height of the ladder slope, and filter out mud and sand.

[0036] The power mechanism 8 includes a first electric push rod 81, the upper end of the first electric push rod 81 is connected to the side of the interception mechanism 6, the bottom end of the first electric push rod 81 is connected to the rear of the upper end surface of the sliding component 3, the middle of the first electric push rod 81 is connected to the second electric push rod 82, the bottom end of the second electric push rod 82 is connected to the front of the upper end surface of the sliding component 3, the power mechanism 8 is connected between the sliding component 3 and the interception mechanism 6, controls the interception mechanism 6 to flip, so that the mud and sand processed inside the interception mechanism 6 can be dumped, so that the interception mechanism 6 can be used for a long time in a cycle.

[0037] The water holding mechanism 9 includes a water bucket 91, both ends of the water bucket 91 are equipped with hanging ears 94, the hanging ears 94 are rotatably connected to the rope 10, the rope 10 includes a steel rope 1001 and a control box 1004, the control box 1004 is fixedly installed on the sliding assembly 3, one end of the steel rope 1001 is fixedly connected to the hanging ear 94, the other end of the steel rope 1001 is fixedly connected to the second hanging ring 32 around the first hanging ring 25, the end of the steel rope 1001 is fixedly installed with a connecting piece 1002, the connecting piece 1002 is fixedly connected to a spring push rod 1003, and the end of the spring push rod 1003 is welded to the first hanging ring 25. On the cross bar 21, the spring push rod 1003 is electrically connected to the control box 1004, and a pressure switch 1005 is installed on the back of the control box 1004. The bottom end of the water bucket 91 is hinged with a connecting frame 92, and the connecting frame 92 is slidably installed inside the slide groove 23, and the upper end surface of the connecting frame 92 and the top of the slide groove 23 are connected with a spring 93. The water bucket 91 is installed below the interception mechanism 6 to receive part of the water filtered out of the interception mechanism 6, and the mud and sand inside the interception mechanism 6 are cleared according to the cleaning action and emptying frequency of the accumulated water inside the water holding mechanism 9, thereby improving the self-cleaning effect of the device.

[0038] The lining 7 is composed of several strip lining curtains, the length of which exceeds the inner wall length of the water collecting box 61, and a fine hole with a diameter smaller than the water screening hole 63 is opened in the middle of the lining 7. The lining 7 is installed inside the interception mechanism 6, and the muddy water is filtered through the fine holes with a smaller filtration coefficient than the water screening hole 63, so as to effectively intercept the mud and sand and prevent soil erosion. When the interception mechanism 6 is turned over, the lining 7 can be poured out from the interception mechanism 6, and the mud and sand can be taken out at one time, thereby avoiding the mud and sand adhering to the inner wall of the interception mechanism 6 and being difficult to pour out, thereby improving the convenience of using the device.

[0039] Specifically, when the device for preventing soil erosion on the Loess Plateau is used: the device is carried as a whole to the loess terrace slope, the crossbar 21 and the column 22 are welded and fixed after adjusting the angles according to the slope and elevation of the terrace slope, the ground nails 24 at the bottom of the crossbar 21 are driven into the soil layer, the fixed rail 2 is fixed as a whole, and then the sliding assembly 3 and the support frame 4 are installed on the crossbar 21, the water-containing mechanism 9 is installed on the column 22, and the upper end of the water-containing mechanism 9 is connected to the rope 10, and the rope 10 is passed through the inner end of the fixed rail 2 and fixed to the sliding assembly 3, and the sliding position of the sliding assembly 3 on the fixed rail 2 is adjusted according to the height of the water-containing mechanism 9;

[0040] During the use of the device, as rainwater washes the soil heavily, the accumulated water accumulates on the loess terrace slope and flows to the lower place with the mud and sand, causing the loss of soil. At this time, the shovel assembly 5 and the interception mechanism 6 are installed at the edge of the terrace slope. The muddy water containing mud and sand flows into the interception mechanism 6 through the shovel assembly 5. The mud and sand are filtered by the interception mechanism 6 and the lining 7, and the mud and sand are retained in the interception mechanism 6. The water flows downward from the interception mechanism 6, and a part of the leaked water is received by the water holding mechanism 9. The water in the water bucket 91 is collected and collected inside the water holding mechanism 9. When the water inside the water holding mechanism 9 is full, the weight of the water holding mechanism 9 and the accumulated water as a whole exceeds the elasticity of the spring 93 and the spring push rod 1003, and the water bucket 91 slides downward along the column 22 as a whole. When it slides to the bottom of the column 22, the bottom of the water bucket 91 tilts and turns along the connecting frame 92 to pour out the accumulated water in the water bucket 91, and the water bucket 91 rebounds to the upper end of the column 22. In the process of the water holding mechanism 9 falling, the other end of the rope 10 is connected to the On the sliding assembly 3, while the water holding mechanism 9 falls and rises, the sliding assembly 3 will slide along the cross bar 21 with the support frame 4, the shoveling assembly 5 and the intercepting mechanism 6. When the sliding assembly 3 drives the control box 1004 to slide to the end of the cross bar 21, the pressure switch 1005 installed on the control box 1004 is squeezed onto the wall of the loess slope, triggering the power supply of the control box 1004. The control box 1004 supplies power to the spring push rod 1003 and the power mechanism 8. The spring push rod 1003 pushes the sliding assembly 3 and the control box 1004 to reset and slide. While sliding, the power mechanism 8 drives the intercepting mechanism 6 to flip along the third hinge 62, pouring out the lining 7 and mud and sand inside the water collecting box 61, and evenly spreading them on the surface of the slope through the shoveling assembly 5, repairing the slope, ensuring the soil stock on the slope and the overall inclination of the slope, thereby strengthening soil and water conservation on the Loess Plateau.
