Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration seepage irrigation, and particularly relates to a seepage irrigation device for river beach ecological restoration. Background Art

[0002] The ecological base of the river beach is fragile. During the dry season, the beach is exposed, the wind and sand are raging, and the vegetation on the river beach has seriously degraded. Therefore, the construction of sand prevention and control, the protection of the bare beach from wind and sand and the ecological restoration are necessary measures to promote the construction of green economy and sustainable development.

[0003] When selecting shrubs for river beach ecological restoration, Tamarix chinensis and Salix cheilophila, which grow rapidly and are drought-tolerant and water-wet-tolerant, are generally selected. The associated shrub is Myricaria paniculata. The mixed sowing of shrubs and grasses includes Hippophae gyantsensis, Elymus dahuricus, Artemisia wellbyi, Festuca elata (plateau type), etc. However, during the dry season when the riverbed water level drops, the groundwater level also drops accordingly (in the river beach, riverbed and deep gravel and cobblestone strata, the groundwater level is almost the same as the riverbed water level). In addition, the sandy soil and pebble soil of the beach itself are difficult to retain water, and coupled with the dry climate, effective seepage irrigation is required to ensure the survival of plants.

[0004] At present, there are various types of seepage irrigation technologies applied in agriculture, forestry and ecological management, mainly including traditional surface irrigation, sprinkler irrigation, micro-irrigation and seepage irrigation.

[0005] For surface irrigation, after the water level is lifted by electric energy through a motor-pumped well (pond) or a diversion canal is dug at a high terrain in the upper reaches of the river, the seepage irrigation water is input into the field through field ditches or pipelines. The water flow forms a continuous thin water layer or small water flow and flows along the field surface. It is a method of irrigating the soil by infiltrating under the combined action of gravity and capillary action, also known as the gravity irrigation method.

[0006] Sprinkler irrigation technology uses a set of special equipment to pressurize the seepage irrigation water or use the terrain height difference for self-pressure, and transports the pressurized water through the pipeline system to the spraying device (i.e., the sprinkler head) to be sprayed into the air and dispersed into small water droplets, which fall to the ground like natural rainfall, and then mainly infiltrate into the soil through capillary force and gravity to irrigate the crops.

[0007] Micro-irrigation technology uses a set of special equipment to add low pressure to the filtered seepage irrigation water or use the terrain drop for self-pressure, and transports it through the pipeline system to a special irrigation device on the last-stage pipeline, so that the water and the chemical fertilizer dissolved in the water moisten the surface soil or the soil under the surface near the root zone of the crop evenly and slowly in a relatively small flow rate. The micro-irrigation method mainly relies on capillary action, and there is also partial gravity action to moisten the soil in a local area near the root zone, so it is also called the local seepage irrigation method. According to the different ways of the small water flow flowing out of the irrigation device, the micro-irrigation method can be divided into multiple types such as drip irrigation method, micro-sprinkler irrigation method, fog spray seepage irrigation, small pipe outflow irrigation, pulse seepage irrigation and spring irrigation method.

[0008] Subsurface irrigation technology is a method of introducing irrigation water into the tillage layer of the field by means of special facilities (pipes or mole holes) built underground or special irrigation devices, and wetting the soil around the irrigation devices by capillary action to irrigate crops.

[0009] However, when the above-mentioned conventional subsurface irrigation technology is applied to ecological restoration, there are some inherent limitations or specific challenges.

[0010] Surface irrigation has the disadvantages of low irrigation uniformity and large water waste.

[0011] Sprinkler irrigation has the disadvantages of large initial investment, high operation and maintenance costs, strong technicality, requiring certain technical personnel for operation and management. In addition, sprinkler irrigation is greatly affected by the wind. When the wind speed is greater than level 3, it is not suitable for sprinkler irrigation.

[0012] Micro-irrigation has the following disadvantages: the aperture of the irrigation device is small and is easily blocked by impurities in the water; since micro-irrigation only wets part of the soil, and the growth of crop roots has a tendency towards water, this will cause the crop roots to concentrate and grow towards the wet area, thus affecting root development, restricting its growth, and also being unfavorable for the crop to absorb and utilize natural precipitation; the micro-irrigation system requires a large number of pipes and irrigation devices, with a relatively high investment; the effect of micro-irrigation on regulating the microclimate in the field is not obvious.

[0013] Subsurface irrigation has the following disadvantages: the surface soil humidity is poor, which is not conducive to the germination of crop seeds and the growth of seedlings, nor is it conducive to the growth of shallow-rooted crops; high investment, complex construction, and difficult management and maintenance. Once the pipeline is blocked or damaged, it is difficult to check and repair; when the technical elements are unreasonable, deep leakage is likely to occur, especially for light soils with strong water permeability, and leakage losses are more likely to occur.

[0014] In addition, the implementation of the above-mentioned various subsurface irrigation methods all requires a terrain elevation difference to form self-pressure or requires electric power water level lifting and pressurization. Excavating on the high-level river beach to the high terrain of the upstream river channel to build a diversion channel has a large amount of earthwork, and it is difficult to erect a power supply grid for the municipal power supply on the river beach, with a high later operation cost. If solar panels are used for power supply, the initial construction and later maintenance costs are relatively large. Summary of the Invention

[0015] In order to solve the above-mentioned technical problems, the present invention provides a subsurface irrigation device for river beach ecological restoration, which makes full use of the local rich wind energy without additional energy consumption; through capillary water absorption and capillary penetration, it is not easy to block the pipes and has low maintenance costs. At the same time, it avoids a large amount of earthwork for building diversion channels and maintains the ecological original state.

[0049] Embodiment 1

[0050] As Figure 1 shown, this embodiment discloses the basic composition of a subsurface irrigation device for river beach ecological restoration, which obtains water sources from underground using water-absorbing materials, converts the absorbed water into an available form and stores it through the action of external power, and then transports the stored water to the area that needs subsurface irrigation using water-conveying materials. It includes the following components:

[0051] A water storage space 1, buried underground, which is a container for accommodating and storing the converted free water.

[0052] A capillary water absorption member 2, configured such that a part of it extends into the underground water table, and the other part of the capillary water absorption member 2 is arranged in the water storage space 1. The capillary water absorption member 2 is a polyvinyl alcohol capillary sponge. Capillarity refers to the phenomenon that a liquid rises or falls inside a thin tubular object due to the difference between the cohesive force and the adhesive force, overcoming gravity. A part of the capillary water absorption member 2 is designed to be able to contact the underground water table (i.e., the free surface of the underground saturated water-bearing zone), so as to automatically absorb water from the underground by capillary action until it reaches the saturated state. The other part of it is located in the water storage space 1, and the water in it is the water bound by capillary force in the material pores.

[0053] A power assembly, which acts on the capillary water absorption member 2 to convert a part of the saturated water adsorbed by the capillary water absorption member 2 into free water stored in the water storage space 1 through mechanical action; the applied mechanical action can be physical methods such as extrusion and vibration, and by mechanical action, the capillary state of the water inside the water absorption member is forcibly destroyed, and the saturated water in it is converted into free water - that is, water that is no longer or less bound by capillary force and can flow due to the action of gravity and the like.

[0054] The capillary water conveyance member 3 has one end disposed in the water storage space 1, and the other end of the capillary water conveyance member 3 passes through the water storage space 1 and extends to the plant root area to be infiltrated. The capillary water conveyance member 3 is a porous polyurethane foam strip, and its principle is similar to that of the capillary water absorption member 2. It absorbs free water from the water storage space 1 and slowly and continuously conveys the water along its own structure to the end.

[0055] Embodiment 2

[0056] In this embodiment, a special movable partition is arranged inside the water storage space 1 to functionally divide the space into a water absorption area and a water storage area. The power assembly drives the movement of this partition to squeeze the water absorption material located in the water absorption area, forcing the water therein to enter the water storage area unidirectionally for subsequent conveyance.

[0057] A slidable unidirectional water-permeable partition 12 is arranged in the water storage space 1. The unidirectional water-permeable partition 12 divides the water storage space 1 into a water storage tank 11 and a water absorption tank. The other part of the capillary water absorption member 2 is arranged in the water absorption tank, and one end of the capillary water conveyance member 3 is arranged in the water storage tank 11. The water-permeable direction of the unidirectional water-permeable partition 12 is from the water absorption tank to the water storage tank 11. The power assembly applies a force towards the water absorption tank to the unidirectional water-permeable partition 12, and the unidirectional water-permeable partition 12 squeezes the capillary water absorption member 2. The lower end of the capillary water absorption member 2 passes through the water absorption tank and extends into the underground water table, and the upper end of the capillary water absorption member 2 fills the water absorption tank.

[0058] When the power assembly drives the unidirectional water-permeable partition 12 to move towards the water absorption tank, since the water absorption tank is filled with the capillary water absorption member 2, the moving partition will squeeze the capillary water absorption member 2, and the forced water will be released therefrom. The squeezed water will enter the water storage tank 11 through the unidirectional water-permeable holes 13 on the unidirectional water-permeable partition 12 and accumulate as free water therein.

[0059] When the force of the power assembly is released or moves in the reverse direction, the partition resets, and the capillary water absorption member 2 reabsorbs and becomes saturated, preparing for the next squeezing cycle, and the water that has entered the water storage tank 11 will not flow back.

[0060] As Figure 3 shown, the unidirectional water-permeable partition 12 is vertically arranged in the water storage space 1, and the side surface of the unidirectional water-permeable partition 12 is in dynamic sealing sliding connection with the inner side surface of the water storage space 1. A plurality of unidirectional water-permeable holes 13 are arranged on the unidirectional water-permeable partition 12, and the unidirectional water-permeable holes 13 can adopt various specific structures, such as: elastic flap type, duckbill valve type, umbrella valve type or other micro-unidirectional valve structures.

[0061] Embodiment 3

[0062] This embodiment provides an embodiment of a power assembly. The wind cup 41 is driven by wind power to rotate, driving a vertical rotating shaft 43 to rotate; through a power conversion mechanism 5 installed inside the water storage space 1, the rotational motion of the rotating shaft 43 is converted into the rotational motion of an eccentric wheel; finally, the rotation of the eccentric wheel is used to push the one-way water passing partition 12 mentioned in the second embodiment, generating a periodic reciprocating motion, thereby realizing the extrusion of the capillary water absorption member 2.

[0063] The power assembly includes a wind power driving assembly 4 and a power conversion mechanism 5. The power conversion mechanism 5 is arranged in the water storage tank 11. The power output end of the wind power driving assembly 4 is connected to the power conversion mechanism 5, and the power conversion mechanism 5 applies a force towards the water absorption tank to the one-way water passing partition 12. The wind power driving assembly 4 is responsible for capturing wind energy and converting it into rotational mechanical energy. The power conversion mechanism 5 is responsible for further converting the rotational energy output by the wind power driving assembly 4 into a force for driving the one-way water passing partition 12 to move.

[0064] The wind power driving assembly 4 includes a wind cup 41, a column 42, and a rotating shaft 43. The lower end of the column 42 is connected to the water storage space 1. The rotating shaft 43 is rotatably arranged inside the column 42. The wind cup 41 is fixedly connected to the upper end of the rotating shaft 43 and is driven to rotate by wind power; the column 42 is arranged vertically and serves as the support of the wind power driving assembly 4. The rotating shaft 43 is rotatably connected to the wind cup 41.

[0065] The power conversion mechanism 5 includes a gear set and a cam 51. The central axis of the cam 51 is rotatably connected to the water storage space 1. The gear set is connected between the cam 51 and the rotating shaft 43 and drives the cam 51 to rotate. The cam 51 abuts against the one-way water passing partition 12. The rotation center of the cam 51 does not coincide with its geometric center, or its outer contour is not circular. When it rotates, its edge or a specific point will generate a reciprocating or oscillating displacement relative to the rotation center, which is often used to convert rotational motion into linear or reciprocating motion.

[0066] This embodiment describes in detail the specific structure of the gear set.

[0067] The gear set includes a pinion 53 and a driving tooth pattern. The pinion 53 is fixedly connected to the lower end of the rotating shaft 43. The driving tooth pattern is coaxially arranged on the cam 51. The pinion 53 meshes with the driving tooth pattern and drives the cam 51 to rotate. The vertical rotating shaft 43 drives the pinion 53 at its lower end to rotate. The pinion 53 meshes with the driving tooth pattern on the cam 51, thereby directly driving the cam 51 to rotate around its own horizontal axis, that is, adopting a transmission method similar to bevel gears or worm gears to realize the power transmission and drive from a vertical axis to a horizontal axis.

[0068] The central axes of the upright column 42, the rotating shaft 43, and the pinion gear 53 are coaxially arranged. The central axis of the cam 51 is coaxially arranged and perpendicular to the central axis of the pinion gear 53. The eccentric direction of the cam 51 (i.e., the direction in which the maximum radius of its contour deviates from the rotation center) is perpendicular to the one-way water passage partition 12.

[0069] Embodiment 4

[0070] This embodiment provides another embodiment of the gear set in the power assembly.

[0071] The power assembly includes a wind-driven component 4 and a power conversion mechanism 5. The power conversion mechanism 5 is arranged in the water storage tank 11. The power output end of the wind-driven component 4 is connected to the power conversion mechanism 5, and the power conversion mechanism 5 exerts a force towards the water suction tank on the one-way water passage partition 12.

[0072] The wind-driven component 4 includes a wind cup 41, an upright column 42, and a rotating shaft 43. The lower end of the upright column 42 is connected to the water storage space 1. The rotating shaft 43 is rotatably arranged in the upright column 42. The wind cup 41 is fixedly connected to the upper end of the rotating shaft 43 and is driven to rotate by the wind force.

[0073] The power conversion mechanism 5 includes a gear set and a cam 51. The central axis of the cam 51 is rotatably connected to the water storage space 1. The gear set is connected between the cam 51 and the rotating shaft 43 and drives the cam 51 to rotate. The cam 51 abuts against the one-way water passage partition 12.

[0074] The above structure is similar to the structure in Embodiment 3. This embodiment provides, as Figure 2 shown, another structure of the gear set.

[0075] The gear set includes a pinion gear 53, a turntable 52, and a large gear 54. The pinion gear 53 is fixedly connected to the lower end of the rotating shaft 43. The cam 51 is coaxially and fixedly connected to the turntable 52. The large gear 54 is coaxially arranged on the turntable 52. The pinion gear 53 meshes with the large gear 54 by teeth and drives the turntable 52 to rotate.

[0076] To prevent the rotation speed of the cam 51 from being too fast, in this embodiment, a turntable 52 is added to slow down the rotation speed of the cam 51. The transmission method of driving a large gear 54 (driven wheel) coaxially and fixedly arranged on the large-diameter turntable 52 by a small gear 53 (driving wheel) fixed on the input rotating shaft 43 is adopted. According to the basic principle of gear transmission, when the small gear 53 drives the large gear 54, the ratio of the output angular velocity to the input angular velocity is equal to the inverse ratio of the number of teeth of the two gears (or approximately equal to the inverse ratio of the radius or diameter when the module is the same). Therefore, by selecting a large gear 54 with a diameter (and its corresponding number of teeth) significantly larger than that of the small gear 53 and installing it on the corresponding large-diameter turntable 52, a transmission pair with a speed reduction function is formed. Even if the rotation speed of the input rotating shaft 43 (and the small gear 53) driven by the wind is relatively high, after being decelerated by the large and small gears 53, the final rotational angular velocity transmitted to the turntable 52 and the cam 51 fixed thereon will be effectively reduced, thereby realizing the regulation of the working speed of the cam 51, which may help extend the service life of the components, optimize the extrusion frequency of the water pump, or reduce mechanical shock.

[0077] Since the diameter of the turntable 52 is larger than the maximum length of the cam 51, when the turntable 52 and the large gear 54 rotate, a part of their trajectories is located in the water suction tank area, and the other part is in the water storage tank 11 area. Therefore, it is necessary to set a through groove adapted to the large gear 54 and the turntable 52 on the one-way water passing partition plate 12, and a part of the large gear 54 passes through the through groove and extends into the water suction tank.

[0078] The central axes of the column 42, the rotating shaft 43, and the small gear 53 are coincidentally arranged, and the central axes of the turntable 52, the cam 51, and the large gear 54 are coincidentally arranged and perpendicular to the central axis of the small gear 53;

[0079] The eccentric direction of the cam 51 is perpendicular to the one-way water passing partition plate 12. The side surface of the turntable 52 is in dynamic seal with the through groove to prevent the free water in the water storage tank 11 from leaking to the water suction tank side through the through groove through which the large gear 54 passes, ensuring effective water isolation between the two boxes.

[0080] Embodiment Five

[0081] The infiltration irrigation device described in this embodiment operates based on the principle of combining wind energy drive, capillary water absorption and water conveyance, and mechanical force conversion of water form.

[0082] Driving stage: When the natural wind blows, the wind cup 41 installed on the top of the device is driven to rotate, and then drives the vertical rotating shaft 43 connected thereto to rotate synchronously. The rotation of the rotating shaft 43 is transmitted through the gear set and drives the cam 51 to rotate around its own axis, pushing the one-way water passing partition plate 12 in contact with it to generate periodic reciprocating linear motion (or swing).

[0083] Capillary absorption stage: The lower end of the capillary water absorption member 2 (polyvinyl alcohol capillary sponge) has extended below the groundwater level of the river beach. Using the capillary action of its own material, it continuously absorbs water from the ground. Under the action of capillary force, the water rises along the water absorption member, making the part located in the water absorption tank reach or approach a saturated state, and the interior is filled with capillary water.

[0084] Water storage stage: When the one-way water-permeable partition 12 moves towards the water absorption tank, it directly squeezes the capillary water absorption member 2 that is located in the water absorption tank and has been saturated with water, forcing the saturated water to be released from the pores of the capillary water absorption member 2 and pass through the partition, flowing into the water storage tank 11.

[0085] Capillary transportation stage: The free water accumulated in the water storage tank 11 is contacted by the starting end of the capillary water transportation member 3 (porous polyurethane foam strip) connected inside it. Also using capillary action, the water transportation member will spontaneously absorb the free water in the water storage tank 11 and continuously transport the water upward and outward along the strip structure. The end of the capillary water transportation member 3 is arranged near the roots of the plants that need to be drip-irrigated, and the water is finally slowly released into the soil through the water transportation member, completing the drip-irrigation of the plants.

[0086] As long as there is enough wind energy to drive the wind cup 41 to rotate, and the groundwater level can continuously supply water, the above-mentioned cyclic process from energy capture, capillary water absorption, mechanical extrusion conversion, one-way transfer to capillary transportation and drip-irrigation will proceed cyclically, realizing the continuous, automatic and low-energy drip-irrigation of the vegetation in the river beach restoration area.
