Description

Technical Field

[0001] This invention relates to the field of atmospheric water resource collection technology, and in particular to an atmospheric water collection device. Background Technology

[0002] Global freshwater resources are fundamental and strategic resources for maintaining the stability of the Earth's ecosystem and supporting the sustainable development of human society. Surface water and groundwater resources are distributed unevenly due to geographical differences. Atmospheric freshwater, however, is found almost everywhere on Earth, from vast oceans to land, from mountains to plains. Wherever there is an atmosphere, there is atmospheric freshwater, unrestricted by geographical conditions or topography. Atmospheric freshwater collection is an important supplementary means of addressing the global freshwater crisis, especially crucial for extremely water-scarce regions such as deserts. While atmospheric freshwater (such as fog and dew) is widely distributed, its capture efficiency is currently low. Existing atmospheric water collection devices mostly use rectangular or square mesh surfaces as water collection structures, which are passive and static water collection structures. They have the following drawbacks: First, existing water collection structures can generally only remain open and cannot dynamically adapt to environmental changes. Atmospheric water collected in the storage tank will evaporate and be lost excessively through the openings of the integrated structure. Second, the shape of the water collection structure cannot change or deform with time or environmental conditions. Its driving force on droplets (base curvature gradient) is fixed. Droplets tend to linger in areas with small base curvature gradients, which is not conducive to improving water collection efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an atmospheric water collection device to solve the problems existing in the prior art, which can ensure the realization of the fog capture and water collection function and greatly reduce evaporation loss.

[0004] To achieve the above objectives, the present invention provides the following solution: This invention provides an atmospheric water collection device, comprising a water storage tank, a control device, a drive device, and at least one flexible water collection body, wherein: The water storage tank is provided with at least one opening, and the opening corresponds one-to-one with the flexible water collection body; The outline shape of each of the flexible water collection bodies matches the outline shape of the corresponding opening, and each of the flexible water collection bodies is fixedly connected to the corresponding opening of the water storage tank. The flexible water collection body is provided with multiple gaps. The control device can keep the drive device on when the atmospheric humidity meets the set conditions. The driving device enables each of the flexible water collecting bodies to deform toward the inside of the water storage tank. When each of the flexible water collecting bodies deforms, the corresponding gap opens along a first direction, which is the width direction of the corresponding gap.

[0005] Preferably, the control device is a humidity switch, which enables the drive device to start when the humidity switch is turned on and enables the drive device to stop when the humidity switch is turned off.

[0006] Preferably, the control device includes an input conductor and an output conductor, the input conductor and the output conductor are arranged opposite to each other, and a gap is left between the input conductor and the output conductor, the minimum value of the gap being less than the capillary length of water; the input conductor is used to connect to the positive terminal of the power supply, and the drive device is connected to the output conductor and the negative terminal of the power supply respectively to form a power supply circuit.

[0007] Preferably, the gap is vertically arranged, and the upper end of the gap gradually decreases from top to bottom.

[0008] Preferably, the driving device includes an electromagnetic coil and an iron core disposed inside the water storage tank. The electromagnetic coil is sleeved outside the iron core, and the two pins of the electromagnetic coil are respectively connected to the output conductor and the negative terminal of the power supply. The flexible water collection body can deform into the water storage tank under the magnetic field of the electromagnetic coil.

[0009] Preferably, the flexible water collection body is made of hydrogel and iron powder composite.

[0010] Preferably, the inner surface of each of the flexible water collection bodies is coated with a hydrophilic coating, and the outer surface of each of the flexible water collection bodies is coated with a hydrophobic coating.

[0011] Preferably, each of the flexible water collection bodies includes at least two rows of flexible units, each row of flexible units includes multiple rhomboid flexible monomers, the flexible monomers in adjacent rows are staggered, and one side of two adjacent flexible monomers in each row is fixedly connected to one end of an adjacent flexible monomer in the adjacent row.

[0012] Preferably, the upper and lower edges of each row of flexible units are sinusoidal.

[0013] Preferably, each of the flexible monomers can be divided into four slot processing areas by a first connecting line and a second connecting line. Each first connecting line intersects with two opposite edges of the corresponding flexible monomer, and each second connecting line intersects with the other two opposite edges of the corresponding flexible monomer. Each slot processing area is processed with at least two slots.

[0014] The present invention achieves the following technical effects compared to the prior art: This invention provides an atmospheric water collection device, comprising a water storage tank, a control device, a drive device, and at least one flexible water collection body. The water storage tank has at least one opening, each corresponding to a flexible water collection body. The outline shape of each flexible water collection body matches the outline shape of its corresponding opening. Each flexible water collection body is fixedly connected to its corresponding opening in the water storage tank, and each flexible water collection body has multiple slits. The control device can control the drive device to remain open when the atmospheric humidity meets a set condition. The drive device can cause each flexible water collection body to deform towards the inside of the water storage tank. When each flexible water collection body deforms, the corresponding slit opens along a first direction, which is the width direction of the corresponding slit. When the atmospheric humidity meets the set condition, the control device controls the drive device to remain open, causing the flexible water collection body to undergo concave deformation, opening the narrow slits in the width direction to form a larger water collection opening, thereby allowing mist to pass through the water collection opening and ensuring the realization of the mist collection function. When the atmospheric humidity does not meet the set conditions, the control device controls the drive device to remain closed, and the flexible water collection body returns to its initial state. Since the gap is much smaller than the water collection port, it can greatly reduce evaporation loss. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] The purpose of this invention is to provide an atmospheric water collection device to solve the problems existing in the prior art, which can ensure the realization of the fog capture and water collection function and greatly reduce evaporation loss.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-12As shown, the present invention provides an atmospheric water collection device 100, including a water storage tank 1, a control device 2, a drive device 3, and at least one flexible water collection body 4. The water storage tank 1 has at least one opening, with each opening corresponding to a flexible water collection body 4. The outline shape of each flexible water collection body 4 matches the outline shape of its corresponding opening, and each flexible water collection body 4 is fixedly connected to its corresponding opening in the water storage tank 1. Multiple slits 401 are provided on each flexible water collection body 4. The control device 2 can control the drive device 3 to remain open when the atmospheric humidity meets a set condition. The drive device 3 can cause each flexible water collection body 4 to deform towards the interior of the water storage tank 1. When each flexible water collection body 4 deforms, the corresponding slit 401 opens along a first direction, which is the width direction of the corresponding slit 401. When the atmospheric humidity meets the set condition, the control device 2 controls the drive device 3 to remain open, causing the flexible water collection body 4 to undergo inward deformation, opening the narrow slits 401 in the width direction to form a larger water collection opening, thereby allowing mist to pass through the water collection opening and ensuring the realization of the mist collection function. When the atmospheric humidity does not meet the set conditions, the control device 2 controls the drive device 3 to remain closed, and the flexible water collection body 4 returns to its initial state. Since the gap 401 is much smaller than the water collection port, it can greatly reduce evaporation loss.

[0022] In this specific embodiment, the control device 2 is a humidity switch. When the humidity switch is turned on, it enables the drive device 3 to turn on, and when the humidity switch is turned off, it enables the drive device 3 to turn off.

[0023] In this specific embodiment, the control device 2 includes an input conductor 201 and an output conductor 202. The input conductor 201 and the output conductor 202 are arranged opposite to each other, and a gap 203 is left between the input conductor 201 and the output conductor 202. The minimum value of the gap 203 is less than the capillary length of water. The input conductor 201 is used to connect to the positive terminal of the power supply. The drive device 3 is connected to the output conductor 202 and the negative terminal of the power supply respectively to form a power supply circuit.

[0024] In this specific embodiment, the gap 203 is vertically arranged, and the upper section of the gap 203 gradually decreases from top to bottom.

[0025] In this specific embodiment, the driving device 3 includes an electromagnetic coil 301 and an iron core 302 disposed inside the water storage tank 1. The electromagnetic coil 301 is sleeved on the outside of the iron core 302, and the two pins of the electromagnetic coil 301 are respectively connected to the output conductor 202 and the negative terminal of the power supply. The flexible water collecting body 4 can deform inward into the water storage tank 1 under the action of the magnetic field of the electromagnetic coil 301. The mist first condenses into water droplets at the upper ends of the input conductor 201 and the output conductor 202. When it reaches the gap 203 position which is smaller than the capillary length of water, the droplets in the gap 203 form a liquid bridge, connecting the input conductor 201 and the output conductor 202 to form a current path. When the outside is dry and there is no fog, the liquid bridge disappears as the water evaporates, thus creating a gap 401 between the input conductor 201 and the output conductor 202 of the humidity switch. The current path is broken, the electromagnetic coil 301 stops working, and the flexible water collection body 4 returns to its initial planar structure under elastic action. This, together with the side wall of the water storage tank 1, seals the water storage tank 1, leaving only a very small gap 401 in the water storage tank 1, preventing most of the water in the water storage tank 1 from evaporating and escaping to the outside, thus achieving the purpose of long-term storage.

[0026] In this specific embodiment, the flexible water collection body 4 is composed of a hydrogel and iron powder composite. Preferably, it is composed of polyvinyl alcohol (PVA) hydrogel and iron powder composite, wherein the mass ratio of iron powder to PVA is 2:1. The hydrogel is physically cross-linked (freeze-thaw cycle: freezing for 12 hours + thawing at room temperature for 2 hours, repeated twice) to form the flexible water collection body 4, with a thickness controlled at 0.5-2 mm and a length and width of approximately 62 mm × 34 mm.

[0027] In this specific embodiment, a hydrophilic coating is sprayed on the inner surface of each flexible water collection body 4, and a hydrophobic coating is sprayed on the outer surface of each flexible water collection body 4.

[0028] In this specific embodiment, a hydrophobic layer is formed by spraying an octadecyl mercaptan ethanol solution (concentration 5-10 mg / mL) onto the outer surface of the flexible water collecting body 4, with a contact angle ≥120°; the inner surface of the flexible water collecting body 4 maintains the original hydrophilicity of the hydrogel, with a contact angle ≤60°, forming a wettability gradient between the inner and outer surfaces.

[0029] In this specific embodiment, each flexible water collection body 4 includes at least two rows of flexible units. Each row of flexible units includes multiple rhomboid-shaped flexible monomers 402. The flexible monomers 402 in adjacent rows are staggered. One side of two adjacent flexible monomers 402 in each row is fixedly connected to one end of an adjacent flexible monomer 402 in the adjacent row. It should be noted that the rhomboid-shaped flexible monomer 402 of this invention does not specifically refer to a strict rhomboid shape, but is a morphological description and approximation. In this specific embodiment, the upper and lower edges of each row of flexible units are sinusoidal, that is, the flexible unit 402 is a rhomboid structure surrounded by a sinusoidal waveform structure.

[0030] In this specific embodiment, each flexible unit 402 can be divided into four slot 401 processing areas by the first connecting line and the second connecting line. Each first connecting line intersects with two opposite edges of the corresponding flexible unit 402, and each second connecting line intersects with the other two opposite edges of the corresponding flexible unit 402. Each slot 401 processing area is processed with at least two slots 401.

[0031] In this specific embodiment, there are two flexible water collection bodies 4, which are fixed on two opposite side walls of the water storage tank 1. The flexible water collection bodies 4 and these two side walls form the front and rear of the water storage tank 1.

[0032] In this specific embodiment, a power supply 5 is also included. The power supply 5 is a battery, which is fixedly connected to the outside of the water storage tank 1. The battery voltage is 12V. A water discharge switch 6 is provided on the water storage tank 1. When the water discharge switch is opened, the water collected in the water storage tank 1 can flow out through the water discharge switch.

[0033] In this specific embodiment, the drive device 3 is fixedly connected to the water storage tank 1 via the support rod 7, forming a magnetic flux density of approximately 0.5T. The electromagnetic coil 301 is connected to the battery via the wire 8.

[0034] In this specific embodiment, the slits 401 are cut out using a laser cutting machine. Each flexible unit 402 is cut with 4-18 vertical slits 401, the width of which is 0.1-0.5 mm, and the spacing between adjacent slits 401 is 1-3 mm. The flexible water collection body 4 is initially a planar structure. Through stretching, it transforms from a planar structure into a three-dimensional wavy, tendril-like structure, with an overall unfolded area between 20 cm² and 22 cm².

[0035] In this specific embodiment, the outer ring sidewall of the flexible water collection body 4 is in complete contact with the inner sidewall of the opening.

[0036] In this specific embodiment, the iron core 302 is located at the center of the electromagnetic coil 301, thereby increasing the magnetic field strength.

[0037] In this specific embodiment, both the input conductor 201 and the output conductor 202 are stainless steel sheets, and there is a planar funnel-shaped gap 401 between the two stainless steel sheets. The gap 401 gradually tightens from top to bottom and then remains unchanged. The shortest gap 203 is about 1 mm, which is less than the capillary length of water. This causes the droplets in the gap 203 to form a liquid bridge, connecting the two stainless steel sheets on the left and right, thus forming a current path.

[0038] The working principle of the atmospheric water collection device 100 of the present invention is as follows: When the external humidity rises and fog forms, the fog first condenses into water droplets on the stainless steel plate of the humidity switch. Under the influence of gravity, these droplets move from the upper inclined surface of the stainless steel plate towards the gradually narrowing gap 203 at the lower end, forming a liquid bridge at the shortest parallel gap 203. This creates a current path, causing the electromagnetic coil 301 to start working and generate a magnetic field. Because the flexible water collecting body 4 contains iron powder, it will move closer to the electromagnetic coil 301 under the influence of the magnetic field, thus stretching the flexible water collecting body 4 and transforming it from a planar structure to a three-dimensional wavy, tendril-like structure. Figure 11 As shown. Due to the presence of flexible water-collecting bodies 4 on both the front and rear sides of the device, under the influence of the magnetic field, both flexible water-collecting bodies 4 will open, allowing mist to pass through the device, thereby improving the overall mist collection efficiency of the device. Simultaneously, due to the presence of gaps 401, the effective stiffness of the gap 401 region is much lower than that of the surrounding intact material region. When subjected to external forces, the gap 401 region is more prone to deformation, acting as a flexible hinge for the entire structure. At these "hinges" of gaps 401, in order to release the huge local stress generated by extreme stretching, the material will spontaneously bend inward and outward, jumping out of the original two-dimensional plane and entering three-dimensional space. Because the gaps 401 are regular, i.e., all are long strips, vertically oriented, the three-dimensional wave-shaped tendril-like structure formed after the flexible water-collecting body 4 deforms, as... Figure 12 As shown, after deformation, the slit 401 forms a wave-shaped unit. This wave structure has a geometric curvature gradient from the crest (the middle region of the long side of the slit 401) to the trough (the two ends of the long side of the slit 401). The curvature at the crest is greater than that at the trough, thus driving the droplets to move directionally from the crest to the trough. During the directional movement, the small droplets 9 continuously converge to form large droplets 10. Then, under the action of the wetting gradient of the external hydrophobic and internal hydrophilic properties of the flexible water collecting body 4, the droplets move towards the internal hydrophilic surface, leaving a clean external hydrophobic surface, laying the foundation for the next fog accumulation. The droplets that have moved to the internal hydrophilic surface will gradually gather downwards under the action of gravity and eventually detach from the flexible water collecting body 4. This invention improves the droplet detachment speed through the synergistic effect of the geometric gradient and the wetting gradient, that is, it allows the gathered droplets to quickly detach from the flexible water collecting body 4 and accumulate at the bottom of the device, thereby improving the fog collection efficiency of the device.

[0039] The water collection efficiency of the flexible water collection body 4 increases with the increase of the number of gaps 401 on the flexible single unit 402, as demonstrated by experiments (experimental data are shown in Table 1 and 2). Figure 13 As shown), Figures 6-8The water collection efficiencies of the flexible monomer 402 with 4, 8, and 18 vertical slits 401 are 2.0625, 2.5432, and 3.3557 times that of a stripeless rectangular structure with the same planar dimensions (62 mm × 34 mm used in the experiment), respectively. Figure 9 As shown, the area of ​​the flexible water collection body 4 was varied to verify the results under the condition of equal area. The experimental results are shown in Table 2 and 3. Figure 14 As shown in the figure), the water collection efficiency of the 6-row flexible monomer 402, 5-row flexible monomer 402, 4-row flexible monomer 402, and 3-row flexible monomer 402 structures is 3.2781, 2.9881, 2.5384, and 2.1656 times that of the stripeless rectangular structure with the same planar dimensions (62 mm × 34 mm used in the experiment), respectively. It can be seen that the flexible water collection body 4 with 6 rows of flexible monomers 402 and 18 vertical slits 401 in the flexible monomers 402 has the highest water collection efficiency, approximately 3.3 times. Experimental tests (experimental data are shown in Table 3 and...) further confirm this. Figure 15 As shown), Figure 14 As shown, the water collection efficiency of the flexible water collection body 4 can be further improved by increasing the wetting gradient. The same structure was tested and found to have a water collection efficiency of up to 5.6708 times that of the flexible water collection body 4 without a wetting gradient, which is much higher than that of the flexible water collection body 4 without a wetting gradient, thus reducing droplet retention.

[0043] This invention utilizes a magnetic field to drive the dynamic deformation of a flexible water collection body 4, constructing an intelligently openable and closable water collection system. This solves the problems of low efficiency and poor environmental adaptability in traditional water collection technologies, achieving efficient capture and directional transport of atmospheric freshwater. Specifically, this invention has the following advantages: First, it can dynamically adapt to water collection: the structure is opened and closed by magnetic field drive, and the flexible water collection body 4 is stretched by magnetic control, transforming it from a planar structure to a three-dimensional wave-like tendril structure. Combined with the setting of a wetting gradient, it accelerates droplet removal and improves water collection efficiency by more than 5 times. Second, it features optimized structural design: it adopts a discontinuous cell + multi-slit 401 structure (18 slits 401 achieve the highest efficiency), increasing the gas-liquid contact area. Single-sided hydrophobic treatment forms a wetting gradient, reducing droplet retention. Third, it features low-energy drive: it uses a non-contact magnetic field drive, eliminating the need for complex mechanical structures and offering durability and ease of maintenance.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
