Description

Technical Field

[0001] This invention relates to the field of slope protection technology, and more specifically, to an ecological slope protection method. Background Technology

[0002] Reservoirs, river embankments, mountains, and roadside slopes often experience soil erosion and landslides. To prevent soil erosion and landslides, slope protection and management are necessary. Currently, the main method for slope protection is to use concrete structures for slope protection.

[0003] To decorate the slope, plants are usually planted on the surface of the slope to achieve ecological slope protection. However, due to the ebb and flow of the river, the river water will periodically wash the plants on the slope. Compared with planting on a flat surface, the water flow on the slope surface is faster and there is less residual water. This will cause the soil on the plant surface to be lost due to repeated washing by the river water. Existing improvements typically involve sealing the plant surface and watering the plants manually from the top. However, the water flow gradually decreases as it flows down the slope, resulting in plants at the bottom of the slope receiving less water and those at the top receiving more, leading to uneven watering.

[0004] In view of this, we propose an ecological slope protection method. Summary of the Invention

[0005] The purpose of this invention is to provide an ecological slope protection system to solve the problem of uneven watering of plants at different heights on a slope, as mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides an ecological slope protection system, comprising a slope protection body and a plurality of equally spaced soil cavities on the slope of the slope protection body. A cover plate is installed on the top of each soil cavity, and a through hole is located at the center of the cover plate. The slope of the slope protection body is provided with equally spaced linearly distributed water guide channels. The curved surface of the water guide channels is provided with multiple sets of vertically equally spaced conical grooves, which are funnel-shaped and have interconnected capillary pores. The capillary pores are connected to the soil cavities, and the taper of the multiple sets of vertically distributed conical grooves decreases progressively. A pumping unit is located at the top of the slope protection body. The pumping unit is used to draw river water from the bottom of the slope protection body and guide it to the top of the water guide channels. When the water flows downwards along the slope inside the guide channels, the conical grooves and capillary pores generate capillary forces on the water flow inside the guide channels, causing the water flow inside the guide channels to be diverted into the soil cavities. The capillary forces generated by the tapered grooves with decreasing taper increase progressively, counteracting the gradually decreasing water flow inside the guide channels, ensuring that the diverted flow rate of the multiple sets of capillary pores at different heights is the same.

[0007] As a further improvement to this technical solution, the pumping unit includes a pumping shell fixedly connected to the top of the slope protection body. The top of the pumping shell is provided with an air inlet, and the center of the pumping shell is provided with a through hole. A drive pulley is rotatably provided at the bottom of the center of the pumping shell. A rotating ring is fixedly installed at the bottom of the drive pulley. Multiple spirally arranged propeller blades are provided at the bottom of the rotating ring. A horizontal tidal pipe is provided at the bottom of the slope protection body.

[0008] As a further improvement to this technical solution, a horizontal tidal pipe is provided at the bottom of the slope protection body, and a vertical air pipe is provided at the top of the slope protection body. The air pipe is connected to the tidal pipe, and the propeller blade is installed inside the air pipe.

[0009] As a further improvement to this technical solution, a generator is also fixedly installed inside the pumping casing. A driven pulley is fixedly connected to the rotating end of the generator. The diameter of the driven pulley is smaller than that of the driving pulley. The driven pulley is connected to the driving pulley via a transmission belt. The generator is electrically connected to a battery pack.

[0010] As a further improvement to this technical solution, a Roots pump is fixedly installed inside the pump housing. The Roots pump includes a pump body and a rotating extrusion component inside the pump body. The Roots pump is also equipped with a rotating motor for driving the extrusion component to rotate. The rotating motor is electrically connected to the battery pack. A suction pipe is conductively connected to the inlet end of the Roots pump, and the suction pipe extends into the tidal pipe. An outlet pipe is conductively connected to the outlet end of the Roots pump.

[0011] As a further improvement to this technical solution, the extruder has a rounded triangular structure, and the three planes on the outer surface of the extruder are provided with inwardly recessed cycloidal grooves. The pump body is equipped with two sets of extruders, and the two sets of extruders are synchronously driven by gears.

[0012] As a further improvement to this technical solution, the drive pulley is a hollow pulley, and a water suction pipe with a through hole is provided at the center of the rotating ring, passing through the through hole at the center of the drive pulley and the center of the rotating ring.

[0013] As a further improvement to this technical solution, the inner diameter of the drive pulley is larger than the inner diameter of the air pipe, the outer diameter of the rotating ring is smaller than the inner diameter of the air pipe, and the top of the rotating ring is provided with a threaded opening, through which the rotating ring is threadedly connected to the bottom of the drive pulley.

[0014] As a further improvement to this technical solution, a diverter is provided at the end of the outlet pipe away from the Roots pump. The bottom of the diverter is provided with outlet holes that correspond one-to-one with the guide channel. The outlet holes face the guide channel. The diverter is hollow inside and connected to multiple sets of outlet holes.

[0015] As a further improvement to this technical solution, the water outlet pipe penetrates the side of the pump housing, and the inner diameter of the water outlet hole is smaller than the inner diameter of the water outlet pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this ecological slope protection, the water guiding channel and conical channel system set on the slope surface utilizes the principle of capillary force to achieve uniform watering of plants. The conical channel adopts a tapered design, so that the capillary pores at different heights generate increasing capillary force. Thus, as the flow rate gradually decreases as the water flows down the slope, the amount of water distributed to each soil cavity is ensured to be consistent by adjusting the magnitude of the capillary force, effectively solving the problem of uneven watering in traditional slope protection.

[0017] 2. In this ecological slope protection, the installation of cover plates prevents river water from directly eroding the plant surface, thus preventing soil erosion and protecting the stable growth of plant roots.

[0018] 3. This ecological slope protection system integrates tidal power generation into the pumping unit. It utilizes the tidal changes in the river channel to drive the propeller blades to generate electricity, which is stored in a battery bank to power the Roots pump. This achieves a self-sufficient pumping system, reducing dependence on the external power grid. It is suitable for remote areas, lowering construction and maintenance costs. The design of the Roots pump ensures the continuity and stability of the pumping process, preventing backflow and improving reliability. The overall structure is compact and efficient, not only enhancing the ecological function of the slope protection but also strengthening its environmental adaptability and sustainability.

[0021] The technical solutions in 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.

[0022] Example 1 Please see Figures 1-9 As shown, this embodiment provides an ecological slope protection, including a slope protection body 1. The slope protection body 1 has a plurality of soil cavities 5 evenly distributed on its slope surface, through which plants can be laid on the slope surface of the slope protection body 1. Since slope protection is often used to prevent the sediment content in rivers from rising, slope protection structures are usually set on both sides of the river to reduce soil erosion on both banks. Because the river water is affected by tides, the river level will rise or fall periodically, which causes the plants planted on the slope to be periodically washed by the river water. However, unlike on flat ground, the soil on the surface of plants on a slope will be loosened by the erosion of the river water, which will lead to soil erosion inside the soil cavity 5. This will cause the plant roots to lose soil protection and wither. Specifically, the differences in soil erosion caused by water flow on inclined planes compared to flat planes are disclosed: When plants are planted on a horizontal surface, they are impacted by the horizontal water flow. Since the direction of the water flow is perpendicular to the direction of gravity, the water flow will not accelerate under the action of gravity. As a result, the horizontal water flow has a relatively low speed when it flows over the plant surface. Furthermore, since the water flow is not affected by gravity, some of the water flow is blocked by the plant branches and leaves and remains on the plant surface, which will not lead to soil erosion. When plants are planted on a slope, the water flow washes over the plant surface. The water flow is affected by gravity on the slope surface, which increases the water flow speed. Due to gravity, the water remaining on the plant surface is reduced. Most of the water flow carries away the soil on the plant surface under the action of gravity, which leads to soil erosion. Therefore, to prevent soil erosion and subsequent wilting of plants planted on the slope surface, a cover plate 4 is installed on top of the soil cavity 5. The cover plate 4 has a through hole in its center. The slope body 1 has linearly distributed, evenly spaced water-guiding channels 3. The curved surface of the water-guiding channels 3 has conical grooves 32, through which capillary pores 31 are connected and communicate with the soil cavity 5. A pumping unit 6 is located at the top of the slope body 1, used to spray water into the water-guiding channels 3. While the cover plate 4 effectively prevents soil erosion, it can also hinder the plants from obtaining water. Therefore, this structure actively replenishes water into the soil cavity 5 through the water-guiding channels 3, conical grooves 32, and capillary pores 31 system, ensuring stable plant growth. Furthermore, the water guiding principle of the water guiding groove 3, the conical groove 32, and the capillary pore 31 is disclosed: When actively watering the plants, the pumping unit 6 can draw water from the bottom of the slope to the top of the slope, and then guide the water evenly into the water guide channel 3. As the water flows down the slope of the water guide channel 3, it will pass through multiple sets of conical grooves 32 and capillary holes 31. The conical grooves 32 and capillary holes 31 are symmetrically arranged on both sides of the water guide channel 3. Therefore, the conical grooves 32 are perpendicular to the direction of water flow. When water flows through the conical groove 32, since the side of the conical groove 32 away from the water guide groove 3 is connected to the capillary hole 31, the conical groove 32 has a capillary absorption effect on the water flowing through the water guide groove 3. Through capillary absorption, some water can enter the conical groove 32 and the capillary hole 31 from the inside of the water guide groove 3, and then flow into the soil cavity 6 to achieve the watering effect. Specifically, the capillary suction principle of the capillary pore 31 and the principle of setting the tapered groove 32 at the end of the capillary pore 31 are disclosed: The capillary pores 31 draw water from the inside of the water channel 3 through capillary force. The core principle of water absorption by the capillary pores 31 comes from the interaction forces between liquid molecules and between liquid molecules and solid tube wall molecules, including the existence of cohesive force and adhesion force. In actual use, multiple sets of conical grooves 32 and capillary pores 31 can be set at the same horizontal height according to the size of the soil cavity 5, so as to ensure that it can generate capillary action while increasing the degree of watering inside the soil cavity 5. Cohesion is the attraction between liquid molecules, which causes the liquid to tend to contract. Adhesion is the attraction between liquid molecules and solid molecules. Capillary action is the result of the "competition" between these two forces. When adhesion is greater than cohesion, the liquid can wet the solid surface. This phenomenon is called wetting (such as water and glass). At this time, the liquid will spread on the solid surface. Due to wetting, the liquid in contact with the inner wall of the capillary will be "pulled up" upward, causing the center of the liquid surface to be concave, forming a concave curved liquid surface. This curved liquid surface will generate an additional pressure (upward), forcing the liquid to rise along the tube wall.

[0023] There is a formula for calculating the relationship between capillary suction height and liquid surface tension: in: h is the height the liquid level rises.

[0024] γ is the surface tension coefficient of the liquid.

[0025] θ is the contact angle between the liquid and the pipe wall, reflecting the degree of wetting.

[0026] ρ is the density of the liquid.

[0027] g is the acceleration due to gravity.

[0028] r is the radius of the capillary pore 31.

[0029] h is positively correlated with the capillary force on the liquid.

[0030] According to the formula, the smaller the radius of the capillary pore 31, the greater the height of the liquid rise, and thus the greater the capillary force. The smaller the contact angle between the liquid and the tube wall in the range of 0° to 90°, the greater the capillary force. Therefore, by controlling the radius of the capillary pore 31 and the taper of the conical groove 32, the magnitude of the capillary force can be controlled. As the water flows down the slope, the capillary pores 31 and conical grooves 32 at the top of the slope come into contact with the water first and absorb a certain amount of water from the water. This results in a reduction in the amount of water that the capillary pores 31 and conical grooves 32 at the bottom of the slope come into contact with. If the cones 32 at the top and bottom have the same taper, the watering effect inside the bottom soil cavity 5 will be lower than the watering effect inside the soil cavity at the top of the slope. Therefore, to overcome the problem of uneven watering in the soil cavities 5 at the top and bottom of the slope, the cone trough 32 at the top of the slope needs to have a larger taper, and the taper of multiple sets of cone troughs 32 needs to gradually decrease along the downward direction of the slope. Example data is provided: the top cone trough 32 has a taper of 60°, the second layer has a taper of 50°, the third layer has a taper of 40°, and the fourth layer has a taper of 30°. The gradually decreasing taper of the cone troughs 32 ensures that the capillary force in the lower layer of the slope is greater than that in the upper layer. Thus, as the water flow gradually decreases as it flows down the slope, the gradually increasing capillary force along the downward direction of the slope helps to achieve the desired effect at the top. The watering effect is consistent with that of the bottom soil cavity 5. In the actual process of processing the slope protection surface, it is easier to open the conical grooves 32 with different tapers on the side of the water guide channel 3 than to open the capillary holes 31 with different inner diameters. Therefore, by changing the taper of the conical grooves 32, the operation difficulty in the actual processing can be reduced. Since the conical grooves 32 with different tapers change the magnitude of the capillary force generated by the capillary holes 31 on the water flow in the water guide channel 3, the capillary force of the top capillary holes 31 is smaller when the water flow is larger, and the capillary force of the bottom capillary holes 31 is larger when the water flow is smaller, thereby achieving the same diversion effect at different heights and thus achieving uniform watering.

[0031] In order to achieve a stable pumping effect, the internal structure of the pumping unit 6 also needs to be disclosed: The pumping unit 6 includes a pumping housing 61 fixedly connected to the top of the slope protection body 1. The top of the pumping housing 61 is provided with an air inlet. The center of the pumping housing 61 is provided with a through hole. The bottom of the center of the pumping housing 61 is rotatably provided with a drive pulley 62. The bottom of the drive pulley 62 is fixedly installed with a rotating ring 69. The bottom of the rotating ring 69 is provided with multiple spirally arranged propeller blades 610. The bottom of the slope protection body 1 is provided with a horizontal tidal pipe 2. The top of the slope protection body 1 is provided with a vertical air pipe 7. The air pipe 7 is connected to the tidal pipe 2. The propeller blades 610 are arranged inside the air pipe 7. The propeller blades 610 enable the pumping unit 6 to generate electricity using tidal energy. The specific principle is as follows: When the river channel experiences tidal phenomena, the river water flows into the tidal pipe 2 during high tide, filling the internal space of the tidal pipe 2. At this time, the bottom of the air pipe 7 achieves an airtight effect through water. When the river water level drops, external air is needed to replenish the internal space of the tidal pipe 2. This generates a unidirectional airflow that enters the tidal pipe 2 from the air inlet at the top of the pump housing 61. When the unidirectional airflow passes through the propeller blade 610, it drives the propeller blade 610 to rotate, which in turn drives the active pulley 62 to rotate through the rotating ring 69. By changing the air pressure in the air pipe 7 through the tidal pipe 2, the unidirectional airflow generated by the change in air pressure is collected to achieve the effect of tidal energy collection. To store the collected tidal energy, a generator 64 is fixedly installed inside the pumping unit 61. A driven pulley 63 is fixedly connected to the rotating end of the generator 64. The diameter of the driven pulley 63 is smaller than that of the driving pulley 62. The driven pulley 63 is connected to the driving pulley 62 via a transmission belt. The generator 64 is electrically connected to a battery pack 65. The tidal energy is converted into electrical energy and stored in the battery pack 65 by the driving pulley 62 driving the driven pulley 63 and the generator 64 to rotate. By collecting tidal energy and storing it as electrical energy, it is possible to avoid powering the pumping unit 6 with external cables during the use of the slope protection system. In some remote areas or mountainous areas where the power grid is not widespread, the pumping unit 6, which can generate its own electricity, will save a lot of cable costs and external power transmission costs, and avoid the maintenance costs of external power transmission cables. After the battery pack 65 has been charged by tidal energy for a period of time, it stores a certain amount of electrical energy. At this time, the battery pack 65 is used to power the Roots pump 66, thereby achieving the effect of pumping water from the bottom of the slope to the top. Therefore, a Roots pump 66 is fixedly installed inside the pump housing 61. The Roots pump 66 includes a pump body and a rotating extrusion member 67 inside the pump body. The Roots pump 66 is also equipped with a rotary motor for driving the rotation of the extrusion member 67. The rotary motor is electrically connected to the battery pack 65. A suction pipe 611 is connected to the water inlet end of the Roots pump 66 and extends into the tidal pipe 2. A water outlet pipe 68 is connected to the water outlet end of the Roots pump 66. Through the unidirectional suction force generated by the rotation of the extrusion member 67 in the Roots pump 66, water in the tidal pipe 2 can be drawn upward through the suction pipe 611, thereby achieving the effect of water transport. Specifically, the working principle of the Roots pump 66 and the reason why the Roots pump 66 was selected as the core pumping component of this device will be disclosed in detail: The Roots pump 66 is a positive displacement vacuum pump that uses two specially shaped rotors to transport gas through synchronous and counter-clockwise rotation within the pump chamber. Two extruders 67 are driven by a pair of gears with a transmission ratio of 1, rotating synchronously in opposite directions within the pump chamber. A small gap (typically 0.1–0.8 mm) is maintained between the extruders 67 and between the extruders 67 and the inner wall of the pump casing, preventing contact between them. The rotation of the extruders 67 draws liquid from the inlet and seals it within the enclosed space formed by the extruders 67 and the pump casing. As the rotors continue to rotate, the drawn-in liquid is pushed in isolation and at an equal volume from the inlet side to the outlet side. During this process, the liquid itself is not compressed. When the top of the extruder 67 passes the edge of the outlet, the enclosed space connects with the high-pressure outlet side. At this point, some of the high-pressure liquid from the outlet side rapidly backflows into the enclosed space, causing a sudden increase in its internal pressure. Subsequently, the extruders 67 push this mixture towards the outlet and discharge it from the pump.

[0032] The Roots pump 66 can generate a continuous unidirectional water flow, thereby achieving the effect of diverting water for irrigation through the water guide channel 3. However, during the pumping process, due to the high slope height, the suction pipe 611 is long and vertical. If the suction force generated by the pump structure is interrupted during the pumping process, the water rising inside the suction pipe 611 will flow back into the tidal pipe 2, thus causing the pumping process to be interrupted. During use, the Roots pump 66 can generate a continuous and uninterrupted suction force on the suction pipe 611 through the continuous rotation of the extrusion member 67. This can prevent the water inside the suction pipe 611 from flowing back, thereby achieving the effect of drawing water upward from the tidal pipe 2.

[0033] To ensure the accurate installation of the suction pipe 611, the positional relationship between the suction pipe 611 and the drive pulley 62 also needs to be defined. The drive pulley 62 is a hollow pulley, and the center of the rotating ring 69 has a through hole. The suction pipe 611 passes through the center of the drive pulley 62 and the center through hole of the rotating ring 69. The hollow structure of the drive pulley 62 and the rotating ring 69 allows the suction pipe 611 to pass through the center and avoids the suction pipe 611 from affecting the rotating drive pulley 62, the rotating ring 69 and the propeller blade 610.

[0034] To ensure that the water outlet pipe 68 can spray water onto multiple sets of water guide channels 3 simultaneously, a diverter is also required at the end of the water outlet pipe 68 away from the Roots pump 66. The bottom of the diverter has water outlet holes that correspond one-to-one with the water guide channels 3, and the water outlet holes face the water guide channels 3. The diverter is hollow inside and connected to multiple sets of water outlet holes. Since the water outlet pipe 68 is close to the Roots pump 66, the water pressure is high when the water flows into the diverter, so it can completely fill the internal space of the diverter in a short time. At this time, the water pressure of multiple water outlet holes is the same, thereby achieving the effect of uniformly diverting water to multiple water guide channels 3.

[0035] The slope protection body 1 and the equally spaced soil cavities 5 set on the slope can achieve the effect of planting plants on the slope surface, and the combination structure of the water guide channel 3 and the pumping unit 6 can achieve the effect of automatic watering of plants. In the initial stage, plants and soil are transplanted into the soil cavity 5 on the slope of the slope protection body 1, and after the transplanting is completed, a fixed cover plate 4 is installed above the plants, with the main stem of the plants extending out from the through hole in the center of the cover plate 4. Subsequently, a pumping unit 6 is installed on the top of the slope protection body 1 and the water outlet position of the pumping unit 6 is adjusted so that the water outlet position of the pumping unit 6 faces the direction of the water guide groove 3 on the inclined surface of the slope protection body 1. When the river channel undergoes tidal changes, the river water periodically enters and flows out of the tidal pipe 2. During the process of the river water flowing out of the tidal pipe 2, negative pressure is generated inside the air pipe 7. The negative pressure generates a one-way airflow inside the air pipe 7. The propeller blade 610 collects the kinetic energy of the one-way airflow and uses the kinetic energy generated by the tidal energy to drive the generator 64 to rotate and generate electricity. The generated electrical energy is stored in the battery pack 65 inside the pumping unit 6. During the watering stage, the battery pack 65 stores a certain amount of electrical energy, which drives the Roots pump 66 to rotate, thereby generating a unidirectional continuous suction force inside the suction pipe 611. The suction force generated by the Roots pump 66 and the suction pipe 611 that extends into the tidal pipe 2 can draw water from the inside of the tidal pipe 2 to the top of the slope protection body 1 and flow out from the outlet pipe 68. After being diverted by the diverter, the water flow is evenly distributed inside multiple water guide channels 3. During the diversion stage, the water flows downward along the slope surface of the slope body 1 inside the water guide channel 3. When the water flows through the top conical channel 32, the water inside the water guide channel 3 is diverted to the conical channel 32 and the capillary channel 31 by the capillary force inside the capillary pore 31. Then, the water in the water guide channel 3 is diverted to the soil cavity 5 through the conical channel 32 and the capillary pore 31. At the same time, the water flow rate inside the water guide channel 3 decreases and continues to flow. When the water flows to the height of the lower conical channel 32, the capillary force generated by the lower conical channel 32 is greater than that generated by the upper conical channel 32 because the taper of the lower conical channel 32 is smaller than that of the upper conical channel 32. This achieves the same water flow rate into the capillary pore 31 by increasing the capillary force when the water flow rate decreases. In the actual setting of the conical groove 32, multiple sets of conical grooves 32 can be set from top to bottom with a gradually decreasing taper according to the inclination angle of the slope body 1. This achieves the effect of balancing the water flow that gradually decreases downward along the slope by increasing capillary force, thereby achieving the effect of consistent watering degree in the soil cavity 5 at the top and bottom.

[0036] The improved ecological slope protection device of this invention has significant advantages, mainly reflected in solving the core problems of traditional slope protection in terms of plant irrigation and soil and water conservation through innovative structural design. Firstly, regarding irrigation uniformity, the device achieves consistent watering on the slope through the precise coordination of the water guide channel 3 and the conical channel 32 system, utilizing the principle of capillary force. Specifically, the conical channel 32 adopts a tapered design (e.g., from 60° at the top to 30° at the bottom), causing the capillaries at different heights to generate increasing capillary force. Thus, as the flow rate naturally decreases as the water flows down the slope, the magnitude of the capillary force is adjusted to ensure that the flow rate in each soil cavity is the same, effectively overcoming the shortcomings of traditional methods where there is excessive watering at the top and insufficient watering at the bottom. Secondly, regarding preventing soil erosion, the installation of the cover plate 4 prevents river water from directly scouring the plant surface, protects the stability of the soil within the soil cavity 5, reduces the risk of root exposure, and improves the durability of the slope protection. Furthermore, the device integrates energy self-sufficiency. The pumping unit 6 utilizes tidal energy to generate electricity, which is driven by pressure changes in the tidal pipe 2 and air pipe 7. This pressure drives the propeller blades to rotate, which in turn powers the generator 64, charging the battery pack 65 and powering the Roots pump 66. This achieves a pumping system with zero dependence on the external power grid, reducing application costs in remote areas and enhancing the device's environmental friendliness and sustainability. Simultaneously, the design of the Roots pump 66 ensures the continuity and stability of the pumping process. The rotation of its extrusion component 67 generates unidirectional suction, preventing backflow and improving overall reliability. Overall, these improvements not only enhance the ecological function of the slope protection but also, through structural optimization and energy innovation, achieve a highly efficient, economical, and environmentally friendly slope protection solution suitable for various terrain conditions.
