Description

Technical Field

[0001] This disclosure pertains to the field of garden irrigation, specifically relating to a garden irrigation device. Background Technology

[0002] In the fields of landscape engineering, slope ecological restoration, and soil and water conservation, efficient and water-saving irrigation of slope vegetation, and effective prevention of soil erosion, are crucial for ensuring vegetation survival rates, enhancing ecosystem stability, and improving engineering durability. Slope topography makes it difficult for traditional surface irrigation water to remain, easily leading to runoff, water waste, and exacerbating the erosion and loss of topsoil and nutrients. Existing technologies have solutions dedicated to rainwater harvesting and reuse to alleviate these problems. For example, Chinese patent document CN218353783U discloses a slope irrigation structure for landscape engineering. This structure, by setting up a water filtration mechanism on the slope and constructing a water storage tank at the bottom of the slope, achieves the collection, filtration, storage, and pumping of rainwater for irrigation, which can utilize rainwater resources to a certain extent and reduce earthwork excavation within the slope.

[0003] However, this "collection-storage-pumping" model primarily relies on passive accumulation to treat sediment (silt) carried down by runoff and ultimately filtered and intercepted. Specifically, the sediment is isolated in a specific area of ​​the water storage tank, treated solely as waste to be processed. Once it accumulates to a certain amount, manual removal and transportation are required. This method has significant limitations: firstly, the intercepted sediment is rich in organic matter and nutrients, which could serve as valuable soil amendments, but current technology does not effectively reuse it on slopes, resulting in resource waste; secondly, the continuous accumulation of sediment encroaches on water storage space, affecting system efficiency, while regular manual dredging significantly increases long-term maintenance costs and operational burdens, making it particularly difficult to implement on steep, large, or remote slopes. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this disclosure is to provide a garden irrigation device that solves the problem that the prior art lacks an effective in-situ recycling mechanism for intercepted sediment in the soil and water conservation process, which leads to the waste of soil resources and additional cleaning and maintenance burden.

[0005] The objective of this disclosure can be achieved through the following technical solutions: A garden irrigation device includes: multiple irrigation chambers, one side of each irrigation chamber having a through hole, through which plant roots can be inserted into the irrigation chamber; Multiple water storage chambers are embedded in the slope, and one side of each water storage chamber is an inclined section. The inclined section has the same inclination angle as the slope, and a water collection port that penetrates the inclined section is opened on the inner side of the inclined section. A repair component is provided on one side of the inclined section; The repair component includes a first baffle and a drive unit. The end of the drive unit is rotatably connected to the first baffle, and the moving direction of the drive unit is set parallel to the slope. When the drive unit is in the retracted state, the first baffle stands upright at the top of the inclined part at an angle perpendicular to the slope, thereby restricting the downward flow of silt. When the drive unit is activated, it drives the first baffle to move upward in a direction parallel to the slope, thereby pushing the silt in front of the first baffle onto the slope.

[0006] In some public disclosures, multiple sets of water storage chambers and repair components are equidistantly arranged along the slope, and the first baffle on the same horizontal plane is arranged laterally along the slope.

[0007] In some disclosures, a connecting pipe is provided between the water storage chamber and the irrigation chamber corresponding to the water storage chamber, and the water storage chamber and the irrigation chamber corresponding to the water storage chamber form a connected structure through the connecting pipe, and the height of the irrigation chamber is lower than the height of the water storage chamber.

[0008] In some disclosures, a filter device is provided on the inner side of the connecting pipe.

[0009] In some disclosures, the drive unit includes an inner rod, an outer rod, and a pressure sensor, with the outer rod fixed to the surface of the inclined portion and the inner rod slidably disposed on the inner side of the outer rod; The inner rod includes a first straight rod, a second straight rod, a first elastic element, and a pressure sensor. The pressure sensor is located between the first straight rod and the second straight rod, and the first elastic element is sleeved on the outside of the pressure sensor. The two ends of the first elastic element are fixedly connected to the first straight rod and the second straight rod, respectively.

[0010] In some disclosures, the repair component further includes a second baffle, which is fixed to the end of the inner cylinder, is arranged parallel to the slope, and has a serrated groove in its forward direction.

[0011] In some disclosures, a second elastic element is fixed to the end of the inner cylinder, and the second elastic element is located at the upper end of the first baffle. The second elastic element applies pressure to the first baffle to bring the first baffle closer to the second baffle.

[0012] In some disclosures, the second elastic element includes an arc-shaped sleeve, an arc-shaped rod, and a spring. The lower end of the arc-shaped sleeve is fixedly connected to the first straight rod, and the arc-shaped rod is slidably connected to the inner side of the arc-shaped sleeve. The end of the arc-shaped rod is fixed with a spring.

[0013] In some disclosures, multiple sets of filter holes are equidistantly arranged below the first baffle.

[0014] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows: A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them; A rotating connection is a connection between parts that allows the parts to rotate relative to each other. Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields. A sliding connection is a connection between parts that allows the parts to slide against each other.

[0015] The beneficial effects of this disclosure are: By combining a movable first baffle with an irrigation chamber featuring through-holes, the design effectively achieves dynamic soil and water circulation restoration on the slope and precise direct irrigation of plant roots. This integrated ecological slope protection system effectively reduces soil erosion and improves irrigation water utilization efficiency. Furthermore, by collecting water in the water storage chamber to replenish the irrigation chamber and repairing the components to maintain the slope cover layer and ensure plant survival, it enhances the growth stability of slope vegetation, reduces long-term manual maintenance costs, and promotes the sustainability of the slope ecosystem.

[0018] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0019] Please refer to Figures 1 to 8 A garden irrigation device includes: multiple irrigation chambers 1, with a through hole 11 on one side of each irrigation chamber 1, through which the roots of plants can be inserted into the irrigation chamber 1. Multiple water storage chambers 2 are embedded in the slope, and one side of the water storage chamber 2 is an inclined part 21. The inclined part 21 has the same inclination angle as the slope. A water collection port 22 that penetrates the inclined part 21 is opened on the inner side of the inclined part 21. A repair component 3 is provided on one side of the inclined part 21; The repair component 3 includes a first baffle 31 and a drive unit 32. The end of the drive unit 32 is rotatably connected to the first baffle 31, and the moving direction of the drive unit 32 is set parallel to the slope. When the drive unit 32 is in the retracted state, the first baffle 31 is erected at the upper end of the inclined part 21 at an angle perpendicular to the slope, thereby restricting the downward flow of silt. When the drive unit 32 is activated, it drives the first baffle 31 to move upward in a direction parallel to the slope, thereby pushing the silt in front of the first baffle 31 onto the slope.

[0020] In normal operation, the first baffle 31 is vertically positioned perpendicular to the slope. When rainwater or sprinkler systems create rainwater on the slope and falls onto it, the water flows downhill due to gravity. The baffle, perpendicular to the slope, intercepts the silt washed down by the rainwater. When silt accumulates in front of the first baffle 31, the drive unit 32 activates, moving the first baffle 31 parallel upwards along the slope, flattening the intercepted silt and redistributing it to exposed or reinforced areas above the slope. By controlling the directional movement of the first baffle 31 along the slope via the drive unit 32, the interception function is transformed into a transport and spreading function. This allows the accumulated sediment to be redistributed to exposed or infertile areas above the slope, achieving a dynamic cycle of "interception-transportation-covering." This not only significantly reduces soil erosion but also transforms the lost sediment into in-situ soil remediation material, continuously improving the growth base for slope vegetation.

[0021] Meanwhile, multiple irrigation chambers 1 distributed across the slope allow plant roots to directly penetrate into them through sidewall openings 11 to absorb water. By setting up irrigation chambers 1 with openings 11, a concealed water source connected to the soil environment is created. Plant roots can naturally penetrate the openings 11 and directly absorb the water stored in the chambers. This method achieves an efficient match between water supply and root needs, reduces irrigation water evaporation and runoff loss, and actively guides and encourages plant roots to develop deeper into the slope.

[0022] The rainwater collected in the water storage chamber 2 can provide a supplementary water source for the irrigation chamber 1; the slope cover layer maintained by the repair component 3 ensures the permeability of the entrance to the irrigation chamber 1 and the survival of the plants.

[0023] Please refer to Figures 1 to 8 Multiple water storage chambers 2 and repair components 3 are equidistantly arranged along the slope, and the first baffle 31 on the same horizontal plane is arranged laterally along the slope.

[0024] By arranging multiple sets of water storage chambers 2 and their repair components 3 equidistantly and laterally along the contour lines of the slope, the entire slope is divided into several independent management units with relatively small vertical heights. When rainfall occurs, the first baffle 31 in each unit is activated synchronously or sequentially. The drive unit 32 moves the first baffle 31 upward along the slope, evenly pushing the intercepted silt to the upper part of the unit or the adjacent upper unit area. This distributed, unitized layout allows water and soil interception, silt backfilling, and slope repair to be carried out simultaneously or stepwise in multiple local areas, thereby achieving systematic and refined management of the entire slope.

[0025] This horizontally distributed contour line layout significantly optimizes system performance. It disperses the overall scouring pressure of a long slope into multiple independent units with small vertical differences, greatly reducing the potential energy and erosive force of water flow at a single point, thereby mitigating the concentrated occurrence of soil erosion.

[0026] Please refer to Figures 1 to 3 A connecting pipe 4 is provided between the water storage chamber 2 and the irrigation chamber 1 corresponding to the water storage chamber 2, and the water storage chamber 2 and the irrigation chamber 1 corresponding to the water storage chamber 2 form a connected structure through the connecting pipe 4, and the height of the irrigation chamber 1 is lower than the height of the water storage chamber 2.

[0027] The water storage chamber 2, located within the slope, is higher than its paired irrigation chamber 1, and the two are connected by a connecting pipe 4, forming a gravity-fed waterway. When rainfall occurs, rainwater flows down the slope and enters the water storage chamber 2 through the collection inlet 22. Subsequently, under gravity, the rainwater stored in the water storage chamber 2 is automatically transported to the lower-positioned irrigation chamber 1 via the connecting pipe 4. The irrigation chamber 1 has through holes 11 on its side wall, allowing plant roots to extend into it, thereby directly and continuously absorbing the water replenished by rainwater within the chamber.

[0028] By collecting natural rainfall on-site and transporting it by gravity, water resources that might otherwise be lost are effectively utilized, providing supplementary irrigation water for plants and improving the overall efficiency of regional water resource utilization. Secondly, it reduces dependence on external irrigation supply, especially during dry seasons or in remote areas without water supply networks, enhancing the self-sufficiency and resilience of the irrigation system. Simultaneously, through direct root absorption, it reduces water loss through evaporation and deep seepage during surface soil transport, improving the effectiveness and targeted nature of water replenishment.

[0029] Please refer to Figure 8 A filter device 41 is provided on the inner side of the connecting pipe 4; When rainwater collected in the storage chamber 2 flows to the irrigation chamber 1 under gravity through the connecting pipe 4, the rainwater first passes through the filter screen. The filter screen intercepts suspended particles, fine silt, and plant debris that enter the storage chamber 2 with the rainwater. The built-in filter screen optimizes water quality management and system maintenance. Its interception of impurities reduces the risk of solid particles entering and depositing inside the irrigation chamber 1, helping to maintain irrigation water quality and thus supporting a more stable water supply to plant roots.

[0030] Please refer to Figures 3 to 6 The drive unit 32 includes an inner rod 322, an outer rod 321 and a pressure sensor 3224. The outer rod 321 is fixed to the surface of the inclined part 21, and the inner rod 322 is slidably disposed on the inner side of the outer rod 321. The inner rod 322 includes a first straight rod 3221, a second straight rod 3222, a first elastic element 3223, and a pressure sensor 3224. The pressure sensor 3224 is located between the first straight rod 3221 and the second straight rod 3222, and the first elastic element 3223 is sleeved on the outside of the pressure sensor 3224. The two ends of the first elastic element 3223 are fixedly connected to the first straight rod 3221 and the second straight rod 3222, respectively. When the soil moves down the slope until it stops in front of the first baffle 31, the first baffle 31 slides along the inner wall of the outer rod 321 under the pressure of the soil. This pushes the first baffle 31 and the first straight rod 3221 towards the side closer to the second straight rod 3222, thereby compressing the first elastic element 3223 (which can be a spring 53) between the first straight rod 3221 and the second straight rod 3222. This compresses the sensitive element (metal diaphragm, silicon diaphragm, or ceramic diaphragm, etc.) of the pressure sensor 3224 until it contacts the second straight rod 3222. The end faces of the two straight rods 3222 come into contact, causing the sensitive element to deform. The pressure on the first baffle 31 is proportional to the volume of the soil. When the amount of soil accumulation is high, the thrust on the first baffle 31 increases. As the thrust on the first baffle 31 increases, the pressure exerted by the first baffle 31 on the first straight rod 3221 increases. Therefore, the pressure on the pressure sensor 3224 increases. The electric telescopic rod can be triggered when the pressure on the pressure sensor 3224 exceeds a certain threshold, thereby controlling the working frequency of the repair component 3.

[0031] Please refer to Figures 3 to 5 The repair component 3 also includes a second baffle 33, which is fixed to the end of the inner cylinder. The second baffle 33 is set parallel to the slope, and a serrated groove 331 is provided in the forward direction of the second baffle 33.

[0032] The soil carried down by the rainwater moves along the slope and eventually accumulates in front of the first baffle 31. When the drive unit 32 drives the first baffle 31 and the second baffle 33 to move up the slope, the second baffle 33 moves in a straight line at an angle parallel to the slope, thereby shoveling down the soil protruding from the slope. The silt layer that has accumulated in front of the first baffle 31 is actively pushed and flattened on the slope. The lower edge of the second baffle 33 acts like a scraper, flattening the irregular protruding soil clods that remain on the slope after the first baffle 31 has been pushed, making the soil backfilled on the top of the slope more evenly and evenly distributed.

[0033] Please refer to Figures 4 to 6 The inner cylinder is fixed with a second elastic element 5 at the end, and the second elastic element 5 is located at the upper end of the first baffle 31. The second elastic element 5 applies pressure to the first baffle 31 to make the first baffle 31 approach the second baffle 33.

[0034] When the electric telescopic rod is retracted to its shortest state, the side wall of the first baffle 31 abuts against the upper end face of the outer cylinder, thereby causing the first baffle 31 to rotate to a state parallel to the upper end face of the outer cylinder. At this time, the second elastic element 5 is in a compressed state. The first baffle 31 and the second baffle 33 are set perpendicularly, and the vertical surfaces of the first baffle 31 and the second baffle 33 form a cavity for accommodating soil. When the drive unit 32 is triggered, the first straight rod 3221 moves upward along the slope, the first baffle 31 separates from the outer cylinder, and the second elastic element 5 applies a rotation force to the first baffle 31 along the rotation axis towards the side closer to the soil. At this time, the soil caused by water and soil erosion is squeezed by the first baffle 31 and the slope, causing the soil at the bottom to adhere to the slope.

[0035] The rotating first baffle 31 exerts a continuous squeezing effect on the soil in its front cavity, pressing the soil against the slope and promoting a tight bond between the soil and the slope. Some soil adheres to the slope under pressure. During this process, the tilt angle of the first baffle 31 is not fixed, but is determined by the dynamic balance between the restoring force of the second elastic element 5 and the resistance of the soil in front: as it moves upward, some soil is compacted and fixed to the slope, the volume of the accumulation gradually decreases, and the resistance of the soil to the first baffle 31 weakens accordingly. The first baffle 31 then continues to increase its tilt angle under the action of elasticity, gradually approaching parallel to the slope, thereby achieving further leveling of the remaining soil at the end of the moving stroke.

[0036] The dynamic rotation design of the first baffle 31 and the second elastic element 5 enables "adaptive compaction and spreading" of the intercepted soil. In the initial stage of the movement, the first baffle 31 applies significant pressure perpendicular to the slope at a large angle, which helps to press the loose soil into the slight depressions on the slope or combine it with the original soil on the slope, improving the adhesion effect. As the soil is compacted and fixed, the first baffle 31 automatically adjusts its angle, gradually turning to a posture that is approximately parallel to the slope, thereby spreading the remaining soil evenly and reducing the formation of local mounds. This dynamic adjustment mechanism enables the restoration process not only to push the soil back to the top of the slope but also to compact and level the backfill soil, significantly improving the surface stability and erosion resistance of the restored slope.

[0037] Please refer to Figure 6 The second elastic element 5 includes an arc-shaped sleeve 51, an arc-shaped rod 52 and a spring 53. The lower end of the arc-shaped sleeve 51 is fixedly connected to the first straight rod 3221, and the arc-shaped rod 52 is slidably connected to the inner side of the arc-shaped sleeve 51. The end of the arc-shaped rod 52 is fixed with a spring 53.

[0038] In use, the curvature of the arc sleeve 51 is the same as that of the arc rod 52. The arc rod 52 can slide along the bending path of the arc sleeve 51. The spring 53 is placed in a bent state on the inner side of the arc sleeve 51. When the first baffle 31 is in a state perpendicular to the slope, the arc rod 52 retracts into the arc sleeve 51, and the spring 53 is in a compressed state at this time. When the first straight rod 3221 extends out, the restriction of the outer cylinder on the first baffle 31 is released, and the first baffle 31 is inclined to rotate by the elastic restoring force of the spring 53.

[0039] The combination of the arc-shaped sleeve 51 and the spring 53 enhances the rotational performance and reliability of the first baffle 31. Its curved path design ensures that the direction of the elastic force always matches the rotational trajectory of the first baffle 31, providing a more direct and efficient power transmission while reducing energy loss and internal stress. This design allows for a wide range of rotation angle adjustments within a compact space and reduces the lateral force or jamming that may occur with the linear spring 53 during rotational applications, resulting in smoother and more precise rotation of the first baffle 31. Simultaneously, the pre-compressed curved spring 53 provides a stable initial driving force, ensuring that the first baffle 31 can respond quickly and begin compaction. The variable characteristic of the elastic force with stroke gives the first baffle 31 excellent self-adaptability, automatically adjusting the compaction strength and inclination rate according to the resistance of the soil ahead, thereby achieving optimal compaction and paving effects under complex and varied slope soil conditions.

[0040] Please refer to Figure 8 The first baffle 31 has multiple sets of filter holes 311 that are equidistantly arranged below it.

[0041] During the initial rain phase, when the first baffle 31 is set perpendicular to the slope, rainwater can pass through the filter holes 311 and flow to the inclined part 21, instead of accumulating directly in front of the first baffle 31, thereby reducing the possibility of the drive unit 32 being accidentally triggered.

[0042] Meanwhile, during the compression process of the first baffle 31, as the original connection between the first baffle 31 and the second baffle 33 separates, excess water flows out along the filter hole 311 and the angle between the first baffle 31 and the second baffle 33, thereby reducing the moisture in the soil used for repair and increasing the viscosity of the soil, which helps to reduce the problem of secondary loss of the repaired slope in a short period of time (before the rain stops).
