Description

Technical Field

[0001] The invention relates to the technical field of land improvement, in particular to a slope soil and water conservation, filtering, drainage and slope consolidation device. Background Art

[0002] Drainage and slope consolidation is achieved by setting up slope drainage ditches, intercepting ditches, underground drainage facilities, etc. to drain water from the surface and interior of the slope in a timely manner, lowering the groundwater level, and reducing water infiltration, softening, and hydrostatic pressure on the slope. At the same time, engineering measures such as retaining walls, anti-slip piles, anchor rods, anchor cables, as well as biological measures such as planting trees and grass, are used to enhance the slope's anti-slip force and stability.

[0003] If natural rainfall or irrigation water cannot be properly channeled, it will easily accumulate on the land, causing the soil to become too wet, affecting the respiration of crop roots and hindering their growth. On the other hand, the indiscriminate flow of water will wash away the soil, carrying away a large amount of surface soil, causing soil erosion, destroying soil fertility and structure, and reducing land productivity. Therefore, a slope soil and water conservation, filtration, drainage and slope consolidation device is needed.

[0004] However, the existing slope soil and water conservation, filtration, drainage and slope consolidation devices have the following shortcomings:

[0005] 1) Currently, the slope soil and water conservation, filtration, drainage and slope stabilization devices on the market all divert natural rainfall water through ditches and pipes to other places to prevent the soil from being soaked and causing it to become sparse, loose and slippery. However, when the soil is not in contact with water for a long time, it is easy to cause the soil to dry out, affecting plant growth. If the soil surface is exposed to the outside for a long time, it will still cause soil erosion and landslide problems.

[0006] 2) If the excess rainwater is simply diverted elsewhere, it can only play a surface treatment role and cannot solve the fundamental problem. When the drainage channel is blocked by debris such as branches and leaves, soil erosion will still occur.

[0007] 3) When filtering a large amount of flowing water, some fine sand will still be lost with the water flow, making the soil and water conservation and slope consolidation work incomplete.

[0008] Therefore, we proposed a slope soil and water conservation, filtration, drainage and slope consolidation device to solve the above problems. Summary of the Invention

[0009] The purpose of the present invention is to provide a slope water and soil conservation filtering drainage and slope consolidation device. First, the device is buried under the land area to be protected. When natural rainfall occurs, the grass planted in the vegetation trough prevents rainwater from directly impacting the soil surface, reducing the possibility of soil being washed away by rainwater. When a large amount of rain falls on the ground, if the deep soil is saturated with moisture and no longer absorbs moisture, if the surface water is also saturated with moisture, excess rainwater will accumulate on the surface of the soil. A large amount of rainwater will soak and soften the surface soil, making it easy for the soil to be lost by water flow. At this time, the surface soil is separated from the deep soil by the vegetation trough. When the surface soil is saturated with moisture, the rainwater can penetrate the surface soil in the vegetation trough and pass through the filter trough and the diversion pipe. The filter holes on the filter plate leak into the diversion pipe. At this time, the filtered rainwater falls from the top of the diversion pipe onto the filter plate. At this time, the rainwater with mud is filtered for the second time, and the flowable liquid falls directly to the bottom of the diversion pipe and flows into the water pipe. At the same time, the filtered mud remains on the filter plate. In order to prevent the mud that has just been filtered from sliding when it still contains a lot of water, multiple slag retaining plates are used to block it and prevent it from sliding, so that the time it stays on the filter plate will be extended, so that the filtered mud can be completely drained of water. Finally, the electric telescopic rod is started to drive the slag retaining plate to slide downward, and then the first motor is turned on to drive the scraper to slide on the filter plate, so that the dry mud is pushed by the scraper to be scraped out into the slag conveying pipe to solve the above problem.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The device of the present invention is pre-buried under the land area to be protected. When it rains naturally, the turf in the vegetation trough prevents rainwater from directly impacting the soil, reducing the risk of soil being washed away. When a large amount of rain falls and the moisture of the deep soil and the surface soil is saturated, the excess rainwater accumulates on the surface of the soil to form water accumulation. The soil after being soaked is prone to softening and loss. The vegetation trough separates the surface soil from the deep soil at this time. After the surface soil is saturated with water, the rainwater penetrates through the surface soil in the vegetation trough, passes through the filter trough and the filter holes of the diversion pipe, and flows into the diversion pipe, preliminarily filtering out some of the soil carried by the rainwater. Then, the rainwater falls from the top of the diversion pipe to the filter plate, and secondary filtration occurs. The flowable liquid falls directly to the bottom of the diversion pipe and flows into the water pipe, while the soil remains on the filter plate. Taking into account that the soil just filtered out contains a lot of water and is easy to slide, multiple slag retaining plates on the filter plate are used to limit and block it, extending its residence time on the filter plate to ensure that the soil is completely drained of water. Finally, the electric telescopic rod drives the slag retaining plate to slide down, and at the same time starts the first motor to drive the scraper to slide along the filter plate, pushing the dry soil into the slag conveying pipe through the scraper. The spring telescopic rod on the scraper can adaptively extend and retract to ensure that the scraper is always attached to the filter plate, thereby avoiding the problem of excessive water shortage in the soil caused by the use of traditional ditch water diversion, which makes the soil dry for a long time and affects the growth of plants, thereby avoiding the problem of the soil surface being exposed for a long time due to the lack of good vegetation on the soil surface, which still leads to soil erosion, and increasing the overall stability of the slope protection.

[0025] 2. In order to maximize the benefits of preventing soil erosion, the present invention uses turf to protect the soil surface from being impacted by rainwater. At the same time, green plants with well-developed root systems are selected in the humus soil trough to reinforce the deep soil. Natural materials such as plant branches and leaves are added to the bottom of the isolation board to improve the air permeability of the soil and the efficiency of rainwater penetration. After humification, the soil can form a granular structure, improve ventilation and water permeability, help the root system of green plants grow, and prevent water accumulation while retaining water and fertilizer. On the other hand, excess rainwater is discharged through the isolation board and the humus soil trough. The holes in the humus seep into the water diversion trough and the water pipe for discharge. The rainwater flows into the fertilizer pipe through the funnel, is blocked by the water collection trough, and is then led to the slow-release fertilizer box by the pipe on it, thereby flushing the solid fertilizer inside the slow-release fertilizer box to form fertilizer water. When there is too much fertilizer water, it is diverted to different soil layers by multi-layer distribution pipes to achieve uniform fertilization, improve the fertility of the soil in the humus soil trough, and enable the green plants planted therein to grow better, thereby protecting the deep soil layer, thereby further increasing the anti-soil loss effect of the device and solving the fundamental problem of easy soil loss and landslide.

[0026] 3. When there is too much soil accumulated in the slag conveying pipe, in order to realize the secondary utilization of the soil, the second motor is started. The second motor drives the screw conveyor to rotate. During the rotation of the screw conveyor, the soil accumulated in the slag conveying pipe will be pushed out, and the pushed out soil will fall on the conveyor belt. At the same time, due to the rotation of the second motor, the transmission belt cooperates with the upper transmission groove and the lower transmission groove to transmit the power, so that the lower transmission wheel fixed thereto rotates, thereby driving the conveyor belt to run synchronously and transporting the soil on the conveyor belt to the ground. The collected soil has been infiltrated and washed by water before, and its fertility has been lost. Therefore, after it is piled on the ground, an appropriate amount of fertilizer is added for composting to restore the fertility of the soil so that it can be put into use later, thereby further realizing the ability of the device to prevent soil erosion, and further increasing the benefits of slope soil and water conservation and slope consolidation.

[0038] The effect achieved by the entire embodiment 1 is as follows: rainwater penetrates the surface soil in the vegetation trough 204, flows into the diversion pipe 202 through the filter trough 203 and the filter holes on the diversion pipe 202, completes the primary filtration, filters out some of the soil, and the rainwater after the primary filtration falls from the top of the diversion pipe 202 onto the filter plate 206 for secondary filtration. After filtration, the clean rainwater flows to the bottom of the diversion pipe 202 by gravity and then flows into the water pipe 1. The filtered soil remains on the filter plate 206 to prevent In order to prevent the wet soil that has just been filtered from sliding down, a plurality of slag retaining plates 207 are provided. The slag retaining plates 207 block the soil and allow the soil to stay on the filter plates 206 for a longer period of time so that the moisture in the soil can be fully drained. After the soil is completely dry, the electric telescopic rod 208 is first started to drive the slag retaining plates 207 to slide downward, and then the first motor 210 is started to drive the scraper 215 to slide against the filter plates 206, scraping the dry soil into the slag conveying pipe 201, completing the rainwater filtration and soil treatment process.

[0039] Example 2, according to Figure 2 - Figure 4 As shown, the vegetation slope stabilization component 3 also includes a water trough 301, which is fixedly connected to the outside of the water pipe 1. The water trough 301 is communicated with the water pipe 1, and the top of the water trough 301 is fixedly connected to the humus soil trough 302.

The top of the slow-release fertilizer box 308 is provided with a water collecting trough 307, and the top of the slow-release fertilizer box 308 is provided with multiple water flow grooves.

[0040] The effect achieved by the entire embodiment 2 is as follows: placing plant branches and leaves at the bottom of the isolation plate 303 makes the soil more breathable and rainwater penetrates faster. The plant branches and leaves are buried between the isolation plate 303 and the humus soil groove 302. After humification, the soil here will form a granular structure. The granular structure can make the soil ventilated and permeable, supply oxygen to the roots of green plants, and help the root system grow. Good permeability can also avoid water accumulation, and the soil's ability to retain water and fertilizer is also enhanced. Excess rainwater penetrates the holes in the isolation plate 303 and the humus soil groove 302, seeps into the water diversion groove 301, and then flows into the water pipe 1 for discharge. At the same time, When rainwater flows into the fertilizer pipe 304 through the funnel 306, it is blocked by the water collection tank 307, flows on the top of the water collection tank 307, and then flows through the pipe on the water collection tank 307 to the surface of the slow-release fertilizer box 308. Finally, the rainwater flows along the flow groove on the surface of the slow-release fertilizer box 308 and flows onto the solid fertilizer in the slow-release fertilizer box 308, washing away some of the substances on the surface of the solid fertilizer to form fertilizer water. When there is too much fertilizer water in the fertilizer pipe 304, the fertilizer water is automatically sent to different soil layers through the multi-layer distribution pipes 305 outside the fertilizer pipe 304, and the soil in different soil layers is evenly fertilized.

[0041] Example 3, according to Figure 4 - Figure 8 As shown, the slag recovery component 4 also includes a second motor 403, the second motor 403 is fixedly connected to the outside of the screw conveyor 402, the screw conveyor 402 is rotatably connected to the inside of the slag conveying pipe 201, the outer size of the screw conveyor 402 is smaller than the inner size of the slag conveying pipe 201, the outer cross-sectional area of the slag retaining plate 207 is smaller than the area of the slideway opened on the inner side of the filter plate 206, the filter plate 206 is slidably connected to the slag retaining plate 207 through the slideway opened on the inner side, an upper transmission groove 404 is opened on the inner side of one end of the screw conveyor 402, a transmission belt 405 is sleeved on the inner side of the upper transmission groove 404, and the transmission belt 405 is connected to the slag retaining plate 207. The other end of the inner side is provided with a lower transmission groove 406, the outer side of the lower transmission groove 406 is fixedly connected to the lower transmission wheel 407, the outer side of the lower transmission wheel 407 is transmission-connected to the conveyor belt 408, the other end of the conveyor belt 408 is provided with an upper transmission wheel 409, the outer side of the upper transmission wheel 409 is rotatably connected to the bracket 410, the bracket 410 is threadedly connected to the ground through bolts, and the lower transmission wheel 407 and the outer side of the lower transmission wheel 407 are provided with a protective cover 401, the outer side of the protective cover 401 is fixedly connected to the connecting plate, the connecting plate is rotatably connected to the lower transmission wheel 407, and the surfaces of the upper transmission groove 404 and the lower transmission groove 406 are provided with an anti-slip layer.

[0042] The effect achieved by the entire embodiment 3 is: when a lot of soil accumulates in the slag conveying pipe 201, in order to reuse the soil, the second motor 403 is started, and the motor drives the screw conveyor 402 to rotate. The screw conveyor 402 pushes the soil accumulated in the pipe out, and the pushed-out soil falls onto the conveyor belt 408. At the same time, because the second motor 403 is rotating, the transmission belt 405 cooperates with the upper transmission groove 404 and the lower transmission groove 406, driving the fixed lower transmission wheel 407 to rotate as well, and the conveyor belt 408 runs synchronously to transport the soil to the ground. The fertility of the collected soil is relatively weak, so after it is piled on the ground, some appropriate fertilizer is added for composting to restore the fertility of the soil for future use.

[0043] The working principle of the whole equipment is as follows: the device is pre-buried under the land block to be protected. When encountering natural rainfall weather, the grass planted in the vegetation trough 204 plays a buffering role, blocking the direct impact of rainwater on the soil surface, reducing the risk of soil being eroded and dispersed by rainwater. When the rainfall is large, the deep soil moisture reaches saturation and can no longer absorb water, and the surface soil moisture is also saturated. At this time, excess rainwater will accumulate on the surface of the soil. A large amount of accumulated water soaks for a long time, causing the surface soil to soften, and it is easy to lose under the action of water flow. In this case, the vegetation trough 204 separates the surface soil from the deep soil by itself. After the surface soil is saturated with water, the rainwater penetrates through the surface soil in the vegetation trough 204, and then flows into the diversion pipe 202 through the filter trough 203 and the filter holes opened on the diversion pipe 202, completing the initial filtration. The rainwater that has been filtered for the first time then flows along the diversion pipe 20 2 continues to seep downward and falls from its top to the filter plate 206 below for secondary filtration. At this stage, the purified flowable liquid falls to the bottom of the diversion pipe 202 by gravity and flows into the drainage pipe 1. At the same time, the soil particles blocked by the filter plate 206 during the filtration process cannot penetrate the filter plate 206 and remain on its surface. Since the soil particles that have just been filtered out and are saturated with water are easy to slide, a plurality of slag retaining plates 207 are installed to form a limit to prevent the soil from sliding, ensuring that the soil stays on the filter plate 206 for a longer time so that the water it contains can be fully drained. Until the soil is completely dry, the electric telescopic rod 208 is started to drive the slag retaining plate 207 to slide downward, and then the first motor 210 is turned on to drive the scraper 215 to fit tightly against the filter plate 206. Under the push of the scraper 215, the dry soil is scraped off the filter plate 206 and enters the slag conveying pipe 201.

[0044] In order to maximize the efficiency and effect of preventing soil erosion, while the turf protects the surface of the soil, green plants with well-developed root systems are planted in the humus soil groove 302 to increase the maintenance and reinforcement of the deep soil, and plant branches and leaves are added to the bottom of the isolation board 303 to increase the air permeability of the soil, so that rainwater has increased infiltration efficiency. When the plant branches and leaves buried between the isolation board 303 and the humus soil groove 302 undergo humification reaction, the soil here forms a granular structure. The granular structure can increase the air permeability and water permeability of the soil, provide oxygen to the roots of green plants and promote the growth of the root system. Its good water permeability can also avoid water accumulation and improve the soil's ability to retain water and fertilizer. Excessive rainwater passes through the isolation board 303 and the humus soil groove 302. The holes penetrate into the water diversion trough 301 and flow to the water pipe 1 for discharge. At the same time, when the rainwater passes through the funnel 306 and enters the fertilizer pipe 304, it is blocked by the water collecting trough 307 and flows on its top surface. The rainwater is then guided and concentrated through the pipe on the water collecting trough 307 to flow to the surface of the slow-release fertilizer box 308. Finally, the rainwater flows through the flow groove on the surface of the slow-release fertilizer box 308 to the solid fertilizer inside the slow-release fertilizer box 308. At this time, the rainwater washes away part of the fertilizer material on its surface to form fertilizer water. When there is too much fertilizer water in the fertilizer pipe 304, the fertilizer water flows out to different soil layers through the multi-layer distribution pipes 305 outside the fertilizer pipe 304, and the soil in different soil layers is evenly and comprehensively fertilized, further increasing the fertility of the soil in the humus soil trough 302.

[0045] When too much soil accumulates inside the slag conveying pipe 201, in order to make the soil available for reuse, the second motor 403 drives the screw conveyor 402 to rotate. When the screw conveyor 402 rotates, the soil accumulated inside the slag conveying pipe 201 is brought out of the slag conveying pipe 201. At this time, the soil brought out falls on the conveyor belt 408. While the second motor 403 rotates, the transmission between the transmission belt 405 and the upper transmission groove 404 and the lower transmission groove 406 drives the lower transmission wheel 407 fixed thereto to rotate. At this time, the conveyor belt 408 runs synchronously and drives the soil on it to the ground. Because the soil collected here is all infiltrated and washed by water, the fertility inside it is weak, so the soil is piled on the ground and fertilizer is added to compost it for subsequent use.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
