Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology, and in particular to an ecological anchoring device with turbine swirling rainwater collection and spiral infiltration functions. Background Technology

[0002] In ecological slope engineering, using plant roots for soil stabilization and slope protection (i.e., "biological reinforcement") is a green and sustainable management method. To address the problems of drought and water shortage on slopes and the difficulty of plant roots penetrating deep, existing technical solutions typically employ diversion pipes or rainwater collection funnels to divert water from the surface soil to the deeper soil layers.

[0003] However, existing ecological diversion devices have the following significant technical shortcomings in actual complex field conditions: (1) The inlet is prone to clogging: Most existing funnels or grid covers adopt static water collection methods. Under the scouring of heavy rain, the mud, sand, dead branches and leaves carried by the slope runoff are easy to clog the inlet, causing the device to fail.

[0004] (2) Hydraulic damage to seedlings: Existing devices usually allow plants to grow directly from the rainwater collection port. The high-speed water flow gathered from the rainwater collection port will directly impact the fragile stem base of the seedlings, which can easily cause the seedlings to fall over, break, or even drown, seriously affecting the initial survival rate.

[0005] (3) Low water utilization rate: In the existing straight pipe diversion structure, water flows vertically and rapidly downward under the action of gravity, which causes most of the water to leak into deeper soil layers quickly, making it impossible to form a lasting moist environment in the target soil layer and making it difficult to effectively induce lateral and deep root development.

[0006] (4) Initial instability: The smooth pipe wall of the rigid pipe body cannot provide sufficient physical anchoring force in the initial stage, and is prone to slippage with the soil.

[0007] In view of this, it is necessary to design an ecological anchoring device with turbine swirl rainwater collection and spiral infiltration functions to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide an ecological anchoring device with turbine vortex rainwater collection and spiral infiltration functions that can avoid the impact of water inlet blockage on water intake efficiency, resolve the contradiction between rainwater collection efficiency and seedling safety, improve water utilization and the anchoring force of the device.

[0009] To achieve the above-mentioned objectives, this invention provides an ecological anchoring device with turbine swirl rainwater collection and spiral infiltration enhancement functions, comprising: The cylinder has an open top and bottom, and spiral blades with decreasing pitch from top to bottom are provided on the outer periphery of the cylinder, so that the side wall of the cylinder is divided into several sections by the spiral blades, and several water seepage holes are provided on the sections; A rain collection plate is located above the cylinder. The rain collection plate is provided with a central through hole communicating with the cylinder and multiple spiral guide ribs distributed circumferentially along the central through hole, so that multiple spiral guide grooves are formed on the surface of the rain collection plate. An annular baffle is located at the central through hole and connected to the rain collection tray via a connector, thereby forming a planting area for planting plants at the central through hole, which is isolated from the spiral guide channel. An annular drainage trough is formed around the outer periphery of the planting area to allow rainwater from the spiral guide channel to flow to the cylinder.

[0010] As a further improvement of the present invention, the surface of the spiral blade is smooth and it is inclined downward away from the axis of the cylinder.

[0011] As a further improvement of the present invention, the downward tilt angle of the helical blade, that is, the angle at which the helical blade tilts downward relative to the vertical line of the cylinder axis, is 3-8°.

[0012] As a further improvement of the present invention, the ratio of the single-sided overhang width of the helical blade to the outer diameter of the cylinder is greater than or equal to 0.5.

[0013] As a further improvement of the present invention, the height of the annular baffle is greater than the height of the spiral guide rib.

[0014] As a further improvement of the present invention, the rain collection disc is connected to the cylinder through a vertical pipe made of a biodegradable material.

[0015] As a further improvement of the present invention, the outer wall of the vertical pipe is provided with an annular fracture groove that is not connected to the interior of the vertical pipe, so that a fracture zone with a relatively small wall thickness is formed at the location of the annular fracture groove, which is easy to break under the pressure of plant growth.

[0016] As a further improvement of the present invention, the wall thickness of the fracture zone is 0.7-1.0 mm.

[0017] As a further improvement of the present invention, the spiral blades are distributed in a gradually changing pitch thread or a segmented variable pitch thread.

[0018] As a further improvement of the present invention, the upper surface of the disc body is provided with a rough surface.

[0019] The beneficial effects of this invention are: 1. This invention utilizes the characteristic that the surface resistance of the spiral blades is much smaller than the pore resistance of the surrounding soil by setting spiral blades with decreasing pitch from top to bottom around the outer periphery of the cylinder. This allows the water flowing out of the seepage holes to preferentially form a water film on the surface of the spiral blades and slide down the spiral channel under gravity. As a result, the water flows a long distance around the surface of the spiral blades while the flow velocity decreases significantly from top to bottom. This results in the water having a longer residence time from top to bottom as it flows into the deep soil at a certain depth. This is beneficial for the water to stay in the deep soil for a long time and to carry out sufficient lateral diffusion, thus achieving "range-extended seepage irrigation".

[0020] 2. The spiral blades of the present invention, with the pitch decreasing from top to bottom on the outer periphery of the cylinder, can achieve "range-extending seepage irrigation" of water flow on the one hand, and enhance the anchoring effect on the other hand, preventing the device from slipping with the soil.

[0021] 3. By setting multiple spiral guide channels on the rain collection plate, the present invention enables the separation of denser silt particles from rainwater by the centrifugal force of the fluid when rainwater flows along the spiral guide channels to the annular drainage trough. This allows the rainwater to flow into the annular drainage trough in a relatively clear state, avoiding blockage of the annular drainage trough and affecting the water intake efficiency.

[0022] 4. By setting a planting area isolated from the spiral guide channel at the center of the rain collection tray and an annular drainage trough located around the periphery of the planting area, the present invention enables rainwater on the rain collection tray to infiltrate in a ring-shaped manner around the periphery of the planting area, avoiding the impact of high-speed water flow on the rain collection tray on the plants or causing the plants to be soaked, thus significantly improving the survival rate of plant seedlings.

[0023] 5. Compared with the existing funnel-shaped diversion port, the design of forming a planting area isolated from the spiral diversion channel by an annular baffle in the central through hole and an annular drainage channel connected to the spiral diversion channel can prevent water from directly rushing into the planting area and damaging the plants. At the same time, it can also make the water flow in a relatively uniform annular distribution to seep down, which can not only moisten the soil inside the cylinder, but also facilitate the water to flow out of the cylinder along the seepage holes and slide down along the spiral blades, so as to form a water gradient in the soil and improve water utilization.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0032] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] like Figures 1-5 As shown, the present invention provides an ecological anchoring device with turbine swirl rainwater collection and spiral infiltration functions, comprising: The cylinder 10 has an open top and bottom, and the outer periphery of the cylinder 10 is provided with spiral blades 11 with decreasing pitch from top to bottom, so that the side wall of the cylinder 10 is divided into several sections 12 by the spiral blades 11, and several water seepage holes 13 are provided on the sections 12. Rain collection plate 20, the rain collection plate 20 is provided with a central through hole that communicates with the upper part of the cylinder 10 and a plurality of spiral guide ribs 21 that are circumferentially distributed along the central through hole, so that a plurality of spiral guide grooves 22 are formed on the surface of the rain collection plate 20. An annular baffle 23 is located at the central through hole and connected to the rain collection plate 20 through a connector, so that a planting area 24 for planting plants is formed at the central through hole, which is isolated from the spiral guide channel 22, and an annular drainage channel 25 is formed on the outer periphery of the planting area 24 for rainwater in the spiral guide channel 22 to flow to the cylinder 10.

[0034] By setting spiral blades 11 with decreasing pitch from top to bottom around the outer periphery of the cylinder 10, on the one hand, the spiral blades 11 can enhance the anchoring effect of the cylinder 10 inserted into the soil. In particular, the decreasing pitch of the spiral blades 11 can gradually enhance the anchoring effect of the cylinder 10 in the vertical downward direction, fully meeting the anchoring requirements of the cylinder 10. On the other hand, the spiral blades 11 can also achieve "range-enhanced infiltration irrigation" by utilizing the principle of "interfacial dominant flow". That is, the surface resistance of the smooth spiral blades 11 is much smaller than the pore resistance of the surrounding soil, so that the water flowing out of the seepage holes 13 will preferentially form a water film on the blade surface and be driven by gravity to slide down the spiral channel. As a result, while the water flows around the surface of the spiral blades 11 for a long distance, the flow velocity also decreases significantly from top to bottom. This makes the water stay longer from top to bottom as it flows to a certain depth of deep soil, which is conducive to the water staying in the deep soil for a long time and carrying out sufficient lateral diffusion, thus achieving "range-enhanced infiltration irrigation".

[0035] For example, such as Figure 5 As shown, the surface of the spiral blade 11 is smooth and it is inclined downwards away from the axis of the cylinder 10. The downward tilt angle of the spiral blade 11, that is, the angle at which the spiral blade 11 tilts downwards relative to the vertical line of the axis of the cylinder 10, is 3-8°. In this example, the downward tilt angle of the spiral blade 11 is 5°. The slight downward tilt angle of the blade away from the axis of the cylinder 10 is conducive to the diffusion and infiltration of water into the surrounding soil along the spiral path.

[0036] For example, the helical blades 11 are distributed in a gradually changing pitch thread or a segmented variable pitch thread, and at least some of the seepage holes 13 on each segment 12 are distributed close to the upper part of the helical blades 11; in this example, the helical blades 11 are segmented variable pitch threads, including a first blade area 111 located on the upper part of the cylinder 10 and a second blade area 112 located on the lower part of the cylinder 10. The first blade area 111 and the second blade area 112 are both set with equal pitch, and the pitch of the helical blades 11 in the first blade area 111 is greater than the pitch of the helical blades 11 in the second blade area 112. Figure 2In the first blade area 111, 2-3 sets of seepage holes 13 are arranged vertically between adjacent spiral blades 11, and 1 set of seepage holes 13 is arranged between adjacent spiral blades 11 in the second blade area 112. Each set of seepage holes 13 includes multiple seepage holes 13 spaced apart along the rotation path parallel to the spiral blades 11. The bottom set of seepage holes 13 in the first blade area 111 is close to the spiral blades 11, and the seepage holes 13 in the second blade area 112 are close to the spiral blades 11, so that rainwater entering the cylinder 10 flows out from the seepage holes 13 in the cylinder 10. Under the pressure of the soil cover, the water flow forms a dominant flow along the smooth, angled surface of the spiral blades 11, and while flowing along the spiral path to diffuse infiltrate the surrounding soil, it also flows downward to swirl and infiltrate the deep soil.

[0037] For example, the ratio of the single-sided overhang width of the helical blade 11 to the outer diameter of the cylinder 10 is greater than or equal to 0.5. By making the width of the helical blade 11 more than 0.5 times the outer diameter of the cylinder 10, it can be ensured that a sufficient flow guiding width is formed to meet the needs of water flow guiding, and to avoid the impact on the water guiding effect of the ecological anchoring device due to the insufficient width of the helical blade 11 affecting the water carrying capacity of the helical blade 11.

[0038] For example, both the cylinder 10 and the helical blade 11 are made of a material with a certain strength so that the cylinder 10 and the helical blade 11 can form an anchor structure to provide sufficient anchoring force. In this example, both the cylinder 10 and the helical blade 11 are made of steel.

[0039] In this example, as Figure 3 As shown, six spiral guide ribs 21 are provided, forming six spiral guide grooves 22 on the surface of the rain collection pan 20. The diameter of the spiral guide grooves 22 gradually decreases towards the center of the rain collection pan 20. By providing multiple spiral guide grooves 22 on the surface of the rain collection pan 20, rainwater can be separated from denser sediment particles by centrifugal force when flowing along the spiral guide grooves 22 to the annular drainage trough 25. This allows the rainwater to flow into the annular drainage trough 25 in a relatively clear state, preventing the annular drainage trough 25 from becoming clogged and affecting the water intake efficiency.

[0040] For example, the disc surface is provided with a rough surface, such as a number of protrusions spaced apart on the disc surface, so as to further promote the separation of denser silt particles from rainwater by utilizing the roughness of the disc surface.

[0041] For example, the height of the annular baffle 23 is greater than the height of the spiral guide rib 21. By isolating the planting area 24 from the spiral guide trough 22 through the annular baffle 23, the rainwater on the rain collection tray 20 can seep down in an annular manner around the outer periphery of the planting area 24, avoiding the impact of the high-speed water flow on the rain collection tray 20 on the plants or causing the plants to be soaked, thus significantly improving the survival rate of plant seedlings.

[0042] In addition, compared with the existing funnel-shaped diversion port, the design of forming a planting area 24 isolated from the spiral diversion channel 22 by the annular baffle 23 in the central through hole and the concave annular drainage channel 25 connected to the spiral diversion channel 22 can prevent water from directly rushing into the central through hole and damaging the plants. At the same time, it can also make the water flow in a relatively evenly distributed annular pattern to seep down. This can not only wet the soil inside the cylinder 10 relatively evenly, but also make the water that seeps down along the side wall of the cylinder 10 quickly flow to the outside of the cylinder 10 along the seepage holes 13 on the side wall and slide down along the spiral blades 11, so as to form a water gradient in the soil and improve water utilization. That is, the annular infiltration method of the rain collection plate 20 can be adapted to the spiral flow guide on the outer wall of the cylinder 10, so that the annular water flow to the cylinder 10 can not only quickly and evenly wet the soil inside the cylinder 10 in a relatively uniform manner, but also facilitate some water flow to quickly diffuse into the soil around the cylinder 10 along the infiltration holes 13 and the spiral blades 11, while also sliding down to the deeper soil, thus realizing "range-extended infiltration irrigation".

[0043] For example, the rain collection tray 20 is connected to the cylinder 10 via a vertical pipe 30. The vertical pipe 30 is made of a biodegradable material. The vertical pipe 30 can be integrated with the rain collection tray 20 or detachably connected to it. In this example, the vertical pipe 30 and the rain collection tray 20 are integrated, and the lower end of the vertical pipe 30 is snapped into the cylinder 10. The vertical pipe 30 is injection molded from biodegradable polylactic acid (PLA) material.

[0044] like Figure 4 As shown, the outer wall of the vertical pipe 30 is provided with an annular fracture groove 31 that is not connected to the interior of the vertical pipe 30. This creates a relatively thin, easily fractured zone at the location of the annular fracture groove 31, which is conducive to fracture under plant growth pressure. The wall thickness of the easily fractured zone is 0.7-1.0 mm. In this example, the annular fracture groove 31 is V-shaped.

[0045] By setting a fracture zone on the vertical pipe 30, the radial pressure generated by the growth and expansion of the plant stem base can be squeezed at the annular fracture groove 31 when it reaches a threshold, causing the groove to break. This creates space between the vertical pipe 30 (i.e., the rain collection tray 20) and the cylinder 10 for the plant roots to extend laterally, preventing the cylinder 10 from binding the plant and restricting the thickening of the plant stems in the later stages of growth. Furthermore, the broken cylinder 10 remains in the soil, providing anchoring force. The vertical position of the fracture zone can be determined based on the growth state of the plant, ensuring that the radial expansion force in the later stages of plant growth can cause the annular fracture groove 31 to break, facilitating lateral growth of the plant stems from the fracture point.

[0046] For example, the connector includes an annular frame 261 sleeved around the outer periphery of the annular baffle 23 and connecting rods 262 connecting the annular frame 261 and the rain collection tray 20. Four connecting rods 262 are spaced apart circumferentially along the annular frame 261. In other examples, the connection between the annular baffle 23 and the rain collection tray 20 can also be achieved directly using the circumferentially spaced connecting rods 262.

[0047] In this example, the length of the cylinder 10 is 60cm, the pitch of the first blade area 111 is 60mm, and the pitch of the second blade area 112 is 30mm; the outer diameter of the cylinder 10 is 40mm, the single-sided overhang width of the spiral blade 11 is 25mm, and the wall thickness of the easily broken area is 0.8mm; the diameter of the rain collection plate 20 is 250mm, and the annular baffle 23 is 40mm higher than the plate surface.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
