Description

Technical Field

[0001] This invention relates to the field of green space irrigation devices, and more particularly to a water-saving irrigation device for landscape green spaces that can store water. Background Technology

[0002] In the field of water-saving irrigation for landscape green spaces, existing automated irrigation systems mostly rely on the coordinated operation of electronic humidity sensors and solenoid valves. While such solutions can achieve on-demand irrigation, they are complex in structure, costly, and the electronic components suffer from decreased reliability and inconvenient maintenance in long-term moist soil environments. Furthermore, these systems typically only perform unidirectional water supply control, failing to effectively recover and recycle naturally infiltrated water or excess irrigation water, thus lacking in the intensive use of water resources. Summary of the Invention

The absorbent body is connected to and supported by the support base. The top of the absorbent body is spaced apart from the lower surface of the corresponding green space unit above it to form a deformable cavity. The absorbent body absorbs excess water falling from the corresponding green space unit above, thereby expanding along the deformable cavity and in the direction close to the green space unit. The adjusting plate is connected to and supported by the absorbent body. When the absorbent body absorbs water and expands, the adjusting plate moves with the expansion of the absorbent body to close the water outlet. When the absorbent body loses water and contracts, the adjusting plate moves with the contraction of the absorbent body to open the water outlet.

[0006] Furthermore, the bottom of the support base is provided with a drainage hole.

[0007] Furthermore, a water-saving irrigation device for landscape green spaces also includes a drainage pipe; the drainage pipe is located below the drainage holes of the plurality of supporting bases.

[0008] Furthermore, the drainage pipes are connected to the water storage tank to collect the water from each of the drainage pipes into the water storage tank.

[0009] Furthermore, the water storage tank is equipped with a water purifier.

[0010] Furthermore, the water supply pipeline is equipped with a water pump, which is used to pump water from the water storage tank into the water supply pipeline.

[0011] Furthermore, the regulating plate is provided with a water inlet and a water sealing surface; the size of the water inlet is smaller than the cross-sectional area of ​​the water outlet.

[0012] Furthermore, the sealing surface is located on the side of the water inlet along the deformed cavity and close to the moisture-absorbing body.

[0013] Furthermore, the support base is provided with a mesh structure, which is used to support the soil covering the green space unit above and allow water in the soil covering the green space unit to flow down.

[0014] Furthermore, the absorbent is one or more composite materials of hygroscopic textile fiber bundles or highly absorbent resin gels.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1.

[0017] 2. Based on the arrangement of the support base in the humidity sensing component being located below the green space unit and on the water outlet path, and the structure of the absorbent body having its bottom connected to the support base and its top spaced apart from the lower surface of the green space unit to form a deformable cavity, the absorbent body can directly receive and absorb excess water falling from above the green space unit, and utilize the deformable cavity to provide physical space and guidance for its expansion towards the green space unit after absorbing water.

[0018] 3. Based on the characteristics of the absorbent body expanding along the deformable cavity towards the green space unit after absorbing water and contracting after losing water, and the design of the regulating plate connected to and supported on the absorbent body, the regulating plate can move synchronously with the volume change of the absorbent body, thereby closing the water outlet when the absorbent body expands and opening the water outlet when the absorbent body contracts, realizing the control of irrigation water supply, thus effectively saving water resources.

[0029] See Figures 1-6 A preferred embodiment of the present invention is described below:

[0030] A water-saving irrigation device for landscape green spaces, characterized in that it includes a water storage tank 1, a water delivery pipe 2, and multiple humidity sensing components 4; the water delivery pipe 2 is connected to the water storage tank 1, and the water delivery pipe 2 is provided with multiple water delivery outlets 3, each water delivery outlet 3 being connected to a different area of ​​green space unit 7 to deliver water from the water storage tank 1 to the corresponding green space unit 7; the humidity sensing components 4 include a support base 401, a moisture absorber 403, and an adjustment plate 404; each support base 401 is located below the corresponding green space unit 7 and on the water outlet path of the corresponding water delivery outlet 3; the moisture absorber 403 is located on the support base 401, and the bottom of the moisture absorber 403 is flush with the support base. 401 is connected to and supported by the base 401. The top of the absorbent body 403 is spaced apart from the lower surface of the corresponding green space unit 7 above to form a deformable cavity 407. The absorbent body 403 is used to absorb excess water falling from the corresponding green space unit 7 above, thereby expanding along the deformable cavity 407 and in the direction close to the green space unit 7. The adjusting plate 404 is connected to and supported by the absorbent body 403. When the absorbent body 403 absorbs water and expands, the adjusting plate 404 moves with the expansion of the absorbent body 403 to close the water outlet 3. When the absorbent body 403 loses water and shrinks, the adjusting plate 404 moves with the shrinkage of the absorbent body 403 to open the water outlet 3.

[0031] The core function of this device is to automatically sense soil moisture and control irrigation through a mechanical structure, thereby achieving effective water conservation.

[0032] Structurally, it mainly consists of three parts: water storage, water delivery, and sensor control. The water storage tank 1 can be any container capable of holding water. The water delivery pipe 2 connects to the water storage tank 1, with each water outlet 3 corresponding to an independent green space unit 7. The key component, the humidity sensing assembly 4, includes a support base 401, a moisture absorber 403, and an adjustment plate 404. The support base 401 is located directly below the green space unit 7 and the water outlet 3, and can be a perforated tray or a mesh plate. The moisture absorber 403, placed on the base, can be made of a water-swellable polymer material, with a gap between its top and the soil surface forming a deformable cavity 407. The adjustment plate 404 is fixed to the moisture absorber 403, and its movement directly opens or closes the water outlet 3.

[0033] When the soil is too moist, the infiltrated water is absorbed by the absorbent body 403, causing it to expand and push the regulating plate 404 to close the outlet and stop water supply. When the soil dries, the absorbent body 403 loses water, and the water in the absorbent body 403 can evaporate from the soil in the upper green space unit 7 or flow away from the perforated tray or grid plate below, thus shrinking and causing the regulating plate 404 to open the outlet and resume irrigation. The entire process is driven entirely by the physical properties of the materials and requires no external control. The movement of the regulating plate 404 can change the opening area of ​​the water inlet 405, thereby changing the water inflow rate and achieving water volume control for irrigation.

[0034] First, install the support base 401 and drainage channel at the bottom of the green space. Install the water supply pipe 2 so that each water outlet is aligned with one support. Place the absorbent body 403 on the support base 401 and connect it to the adjusting plate 404, adjusting the gap between it and the bottom of the soil. After covering with soil, the system will start to operate automatically: supplying water when the soil is dry and stopping watering when the soil is wet, realizing autonomous water-saving irrigation.

[0035] It is understandable that the structural design of the water storage tank 1, the water supply pipe 2 connected to it, and the multiple water outlets 3 set on the pipe enables the device to deliver irrigation water from a central water source to different areas of the green space units 7, laying the foundation for regional independent humidity control. Based on the arrangement of the support base 401 in the humidity sensing component 4 below the green space unit 7 and on the water outlet 3 outlet path, and the structure of the moisture absorber 403 with its bottom connected to the support base 401 and its top spaced apart from the lower surface of the green space unit 7 to form a deformable cavity 407, the moisture absorber 403 can directly receive and absorb excess water falling from above the green space unit 7, and use the deformable cavity 407 to provide physical space and guidance for its expansion towards the green space unit 7 after absorbing water. Based on the characteristics of the absorbent body 403 expanding along the deformable cavity 407 towards the green space unit 7 after absorbing water and contracting after losing water, and the design of the regulating plate 404 connected to and supported on the absorbent body 403, the regulating plate 404 can move synchronously with the volume change of the absorbent body 403, thereby closing the water outlet 3 when the absorbent body 403 expands and opening the water outlet 3 when the absorbent body 403 contracts, thus realizing automatic control of irrigation water.

[0036] Preferably, the bottom of the support base 401 is provided with a drainage hole 408. The drainage hole 408 at the bottom of the support base 401 is mainly used to drain excess water accumulated in the support base 401 in a timely manner, to prevent the moisture absorber 403 from being affected by long-term immersion in water, thus affecting its normal water absorption expansion and water loss contraction functions, and to ensure that the humidity sensing component 4 can accurately respond to changes in the moisture content of the green space.

[0037] Over time, the drain hole 408 allows some of the water absorbed by the absorbent body 403 to flow out naturally under gravity, preventing the absorbent body 403 from remaining in an expanded state due to water retention after the water supply stops. This ensures that the absorbent body 403 can circulate according to the real-time changes in soil moisture, maintaining the accuracy of the regulating plate 404's control over the water outlet 3.

[0038] The drain hole 408 also promotes the natural evaporation of moisture by increasing air circulation. When the ambient temperature is high or the ventilation conditions are good, it accelerates the discharge of excess moisture in the absorbent body 403 and the support base 401, further improving the response speed and working reliability of the entire humidity sensing component 4, making irrigation control more precise and efficient.

[0039] Preferably, a water-saving irrigation device for landscape green spaces also includes a drainage pipe 5; the drainage pipe 5 is located below the drainage holes 408 of multiple support bases 401. The core function of this device is to collect and divert excess water discharged from the support bases 401 through the drainage pipe 5 system.

[0040] Structurally, the drainage pipe 5 is installed below the drainage holes 408 of multiple support bases 401. This pipe can be made of common drainage materials such as PVC pipe, PE pipe, or concrete drainage channels, and its cross-sectional shape can be circular, rectangular, or other structural forms suitable for water flow. The drainage pipe 5 extends along the arrangement direction of the support bases 401, ensuring that the drainage holes 408 of each support base 401 are connected to the drainage pipe 5.

[0041] Its working principle is based on gravity drainage. When water in the support base 401 is discharged through the drain hole 408, it naturally flows into the drainage pipe 5 below under the action of gravity. The drainage pipe 5 collects these dispersed water flows to form an organized drainage system, preventing water from accumulating disorderly at the bottom of the green space.

[0042] After laying the support base 401, install the drainage pipe 5 directly below all the drainage holes 408 of the support base 401. Ensure that the water from each drainage hole 408 falls directly into the drainage pipe 5. The drainage pipe 5 maintains an appropriate slope so that the collected water can flow by gravity to the designated discharge point or recycling device. This structurally ensures that all water discharged from the support base 401 can be effectively collected and diverted.

[0043] Preferably, the drainage pipes 5 are connected to the water storage tank 1 to collect the water from each drainage pipe 5 into the water storage tank 1. The core function of this device is to transport the water collected by the drainage pipes 5 back to the water storage tank 1, thereby realizing the recycling of irrigation water.

[0044] Structurally, the drainage pipe 5 is connected to the water storage tank 1 via a piping system. The connection can be a direct pipe connection, or a collection well can be installed at the end of the drainage pipe 5 before connecting it to the water storage tank 1 via a booster pump. A simple filtration device, such as a filter screen, can be installed at the connection point between the drainage pipe 5 and the water storage tank 1.

[0045] Its working principle is based on the natural guidance or dynamic transport of water flow. The water collected in the drainage pipe 5 flows to the water storage tank 1 under the action of gravity, or is transported to the water storage tank 1 by a lifting device such as a water pump. This process allows the water discharged from the green space to return to the water storage system.

[0046] Preferably, the water storage tank 1 is equipped with a water purifier. The core function of this device is to purify the water returning to the water storage tank 1 through the water purifier, ensuring the cleanliness of the irrigation water.

[0047] Structurally, the water purifier is installed inside the water storage tank 1 or connected to the inlet pipe of the water storage tank 1. The purifier can employ different purification methods such as physical filtration, chemical treatment, or biological purification, including but not limited to purification units such as filter screen filtration, activated carbon adsorption, and ultraviolet disinfection.

[0048] Its working principle is based on the water treatment effect of the purification medium. When the water flowing back from the drain pipe 5 enters the water storage tank 1, the water flows through the water purifier, and the impurities, sediments or microorganisms and other pollutants in it are intercepted, adsorbed or inactivated by the purification medium, so that the water quality stored in the water storage tank 1 is improved.

[0049] Preferably, the water supply pipeline 2 is equipped with a water pump 6, which is used to pump water from the water storage tank 1 into the water supply pipeline 2. The core function of this device is to provide a stable water supply pressure to the water supply pipeline 2 through the water pump 6, ensuring the normal operation of the irrigation system.

[0050] Structurally, the water pump 6 is located at the connection between the water supply pipeline 2 and the water storage tank 1. This water pump 6 can be of different types, such as a submersible pump, centrifugal pump, or pipeline pump, with its power and head selected according to the scale of the irrigation system and water pressure requirements. Its working principle is based on the mechanical pressurization effect of the pump. When the irrigation system needs water, the water pump 6 starts working, drawing water from the water storage tank 1 and pressurizing it into the water supply pipeline 2, establishing the necessary water supply pressure for the entire pipeline system, allowing the water to reach each green space unit 7 through the water outlet 3.

[0051] Preferably, the regulating plate 404 is provided with a water inlet 405 and a water sealing surface 406; the size of the water inlet 405 is smaller than the cross-sectional area of ​​the water outlet 3. The core function of this device is to control the water flow rate through the water inlet 405 on the regulating plate 404.

[0052] Structurally, the regulating plate 404 is provided with a water inlet 405 and a sealing surface 406, wherein the opening area of ​​the water inlet 405 is smaller than the cross-sectional area of ​​the water outlet 3. The water inlet 405 can be a circular, square or other regular shape opening, and the sealing surface 406 is a solid area on the regulating plate 404 used to completely seal the water outlet 3.

[0053] Its working principle is based on the throttling effect of the water inlet 405 on the water flow. When the regulating plate 404 is in the open position, the water flow can only flow out through the smaller water inlet 405, forming a restricted flow; when the regulating plate 404 is completely closed, the sealing surface 406 completely seals the water outlet 3, realizing the cut-off of water flow. This structure enables the irrigation system to achieve flow regulation from fully open to fully closed.

[0054] Preferably, the sealing surface 406 is located on the side of the water inlet 405 along the deformable cavity 407 and close to the absorbent body 403. The core function of this device is to ensure that the regulating plate 404 can effectively seal the water outlet 3 when the absorbent body 403 expands by designing the specific position of the sealing surface 406.

[0055] Structurally, the sealing surface 406 is located on the side of the water inlet 405 near the moisture absorber 403. This arrangement ensures that the expansion direction of the sealing surface 406 and the moisture absorber 403 is consistent, guaranteeing that the moisture absorber 403 can directly push the sealing surface 406 to cover the water outlet 3 during the expansion process.

[0056] Its working principle is based on the precise correspondence of the direction of movement. When the absorbent 403 absorbs water and expands, it moves along the deformable cavity 407 towards the green area. At the same time, the water-sealing surface 406, which is set in the direction of expansion, is pushed synchronously until it completely covers and seals the water outlet 3. This structural design ensures a direct linkage between the water-sealing action and the expansion movement of the absorbent 403.

[0057] Preferably, the support base 401 is provided with a mesh structure, which is used to support the soil covering the upper green space unit 7 and allow water within the soil covering the green space unit 7 to flow down. The core function of this device is to ensure smooth water infiltration while supporting the upper soil through the mesh structure.

[0058] Structurally, the mesh structure is set on the upper surface of the support base 401 and can be made of metal wire mesh, plastic mesh, or other porous permeable materials. The mesh size of the mesh structure can support the weight of the soil covering the green space unit 7 above, while allowing water and fine particles to pass through.

[0059] Its working principle is based on the dual function of the mesh structure. On the one hand, the mesh structure provides a stable support platform for the soil covering of the upper green space unit 7; on the other hand, when irrigating or raining, the water penetrates the soil layer under the action of gravity and can smoothly seep downward through the mesh, enter the support base 401 and be absorbed by the moisture absorber 403 or discharged through the drainage hole 408.

[0060] Preferably, the absorbent 403 is one or more composite materials, namely, a bundle of hygroscopic textile fibers or a superabsorbent resin gel. The core function of this device is to achieve reliable humidity sensing through the absorbent 403 made of a specific material.

[0061] Structurally, the absorbent 403 is made of a material consisting of absorbent textile fiber bundles, superabsorbent resin gel, or a combination of both. The textile fiber bundles can be woven from natural fibers such as cotton and linen or synthetic fibers, and the superabsorbent resin gel can be a high-molecular-weight absorbent material such as sodium polyacrylate.

[0062] Its working principle is based on the hydrophilic properties of the material. When the absorbent 403 comes into contact with water, the textile fibers absorb water through capillary action, and the superabsorbent resin absorbs water through molecular expansion. When the two are combined, they have both rapid water absorption and efficient water retention properties, ensuring that the absorbent 403 can accurately respond to humidity changes and generate sufficient deformation.

[0063] In summary, based on the structure of the water storage tank 1, the water supply pipe 2, and the multiple water outlets 3 thereon, water supply from the central water source to different green space units 7 is realized. By placing the support base 401 in the humidity sensing component 4 below the green space unit 7 and on the path of the water outlet 3, and by connecting the bottom of the absorbent body 403 to the support base 401 and the top of the absorbent body 403 to form a deformable cavity 407 that is spaced apart from the lower surface of the green space unit 7, the absorbent body 403 can directly absorb the infiltrated water, and the deformable cavity 407 provides space and guidance for the expansion of the absorbent body 403 towards the green space unit 7 after water absorption. Furthermore, by utilizing the characteristics of the absorbent body 403 expanding along the deformable cavity 407 after absorbing water and contracting after losing water, and by utilizing the structure of the adjusting plate 404 connected to and supported by the absorbent body 403 and moving synchronously with the volume change, the automatic on / off control of closing the water outlet 3 when the absorbent body 403 expands and opening the water outlet 3 when it contracts is realized, forming a complete mechanical adaptive irrigation system.
