DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The purpose of the present invention is to provide a water collecting device to solve the problems existing in the above-mentioned prior art and improve the water collecting efficiency.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 16 As shown, this embodiment provides a water collecting device 100, including: a water collecting structure, a water seal structure 2 and a water storage structure 3, the water collecting structure includes a plurality of water collecting components 1, the water collecting components 1 are spirally arranged from the upper end of the water collecting component 1 to the lower end of the water collecting component 1, the lower end of the water collecting component 1 extends into the water seal structure 2 or is located above the water seal structure 2, the water seal structure 2 is located on the water storage structure 3, the water collected by the water collecting structure can enter the water storage structure 3 through the water seal structure 2, and the water seal structure 2 can also close the water storage inlet 10 of the water storage structure 3.

[0039] In this embodiment, the water collection component 1 can directly use spiral cutting waste. The spiral water collection component 1 can disturb the airflow, thereby increasing the probability of the fog droplets in the air colliding with the fog-facing surface of the water collection component 1 and condensing, thereby increasing the condensation speed of the fog droplets. Fig.10 and Fig.11 As shown, the air flow speed increases at the water collecting assembly 1 .

[0040] In this embodiment, the water collection component 1 is vertically arranged, and the fog facing surface of the water collection component 1 is inclined. Specifically, the upper end of the fog facing surface of each circle of the water collection component 1 is inclined from the outside to the lower end of the fog facing surface. In each circle of the water collection component 1, the water collection component 1 forms a structure similar to an inverted pagoda, that is, in each circle of the water collection component 1, the small end is at the bottom and the large end is at the top. The width of the fog facing surface is on the millimeter scale. The fog beads are in contact with the fog facing surface, and the fog facing surface is inclined downward, thereby ensuring that the condensed and grown fog beads will be driven by the interfacial tension and gravity, and gradually move downward along the surface of the water collection component 1. In this process, they gradually merge with the tiny fog beads along the way, and the spiral water collection component 1 also enables the fog beads to sweep across each circle of the fog facing surface along the way, thereby leaving a clean fog facing surface to prepare for the next round of condensation. The vertically arranged water collection component 1 allows the fog facing surface of the water collection component 1 to always remain clean, and the condensation speed of the fog beads can be maintained at a high level, thereby achieving the purpose of efficient automatic water collection. Figures 12 to 16As shown, the mist drops move directionally on the water collection assembly 1 as time changes.

[0041] The water collection component 1 of this embodiment was used to conduct a comparative experiment with the prior art to collect fog and collect water. Five groups were tested for half an hour each. The fog-facing surface area of ​​the water collection component 1 was 40*50mm, and the control group was a 40*50mm flat plate. The test found that the water collection capacity of the water collection component 1 of this embodiment in half an hour was 1.91±0.32g, and the water collection capacity of the flat plate of the control group in half an hour was 0.81±0.07g. It can be found that the water collection speed of the water collection component 1 of this embodiment is increased by 1.39±0.59 times.

[0042] In this embodiment, the water seal structure 2 can be prepared by 3D printing. The water seal structure 2 includes a water seal body 4 and a cover plate 5. The water seal body 4 extends upward to form a baffle 9. The cover plate 5 is located on the water seal body 4 and on the inner side of the baffle 9. A plurality of through holes 6 are arranged on the cover plate 5. The diameter of the through holes 6 is 0.1 mm to 0.8 mm, preferably 0.5 mm. The water seal body 4 is provided with a water seal inner cavity 7. The water seal inner cavity 7 is used to hold water. The lower end of the water seal body 4 is provided with a water seal outlet 8. The diameter of the water seal outlet 8 is 0.7 mm to 1.2 mm, preferably 1 mm. The cover plate 5 is located above the water seal outlet 8. The distance between the lower surface of the cover plate 5 and the water seal outlet 8 is 15 mm to 25 mm, preferably 20 mm. The cover plate 5 and the water seal outlet 8 are both hydrophilically treated using a plasma generator. When in use, the water seal inner cavity 7 is filled with water in advance, thereby ensuring that the collected mist drops can smoothly pass through the water seal structure 2 into the water storage structure 3 and preventing the collected mist water from evaporating and dissipating again.

[0043] In this embodiment, the sum of the interface pressure generated by water at the cover plate 5 and the interface pressure generated by water at the water seal outlet 8 is greater than the water pressure in the water seal inner cavity 7. The diameter R1 of the through hole 6 of the cover plate 5 is 0.5 mm, the diameter R2 of the water seal outlet 8 is 1 mm, the surface tension γ of water is 72 mN·m, and the water density ρ is 1000 kg / m 3 , gravitational acceleration g = 9.8 m / s 2, the distance h from the water seal outlet 8 to the cover plate 5 is 20mm, so the sum of the interface pressure generated by the water at the cover plate 5 and the interface pressure generated by the water at the water seal outlet 8, Δp, is: Δp = 2γR1 + 2γR2 = 2×72 / 0.25 + 2×72 / 0.5 = 864Pa> ρgh = 196Pa, so the upward force generated by the sum of the interface pressure generated by the water at the cover plate 5 and the interface pressure generated by the water at the water seal outlet 8 is sufficient to resist the pressure generated by the liquid column of the water in the water seal structure 2. When there is no fog water gathered on the upper side of the cover plate 5, the sum of the interface pressure generated by the water at the cover plate 5 and the interface pressure generated by the water at the water seal outlet 8 can still be relied on to ensure that the water inside the water seal structure 2 will not flow out along the water seal outlet 8 below, ensuring that the inside of the water seal structure 2 is always full of water.

[0044] In this embodiment, the water seal body 4 is funnel-shaped, and the water seal outlet 8 is arranged at the center of the lower end of the water seal body 4. The taper of the water seal body 4 matches the taper of the upper end of the water storage structure 3, and both are about 2. The water seal structure 2 is arranged on the water storage structure 3. Since the taper of the water seal body 4 matches the taper of the upper end of the water storage structure 3, the connection sealing of the water storage structure 3 and the water seal structure 2 is ensured, and the accumulated mist droplets are prevented from evaporating again and escaping into the air.

[0045] In this embodiment, the water storage structure 3 is provided with a water storage cavity 14, a water storage inlet 10 is provided at the upper part of the water storage structure 3, the water seal structure 2 can be connected with the water storage inlet 10, and the water storage structure 3 is also provided with a water storage outlet 11, and a valve 12 is provided at the water storage outlet 11.

[0046] In this embodiment, a vent hole 13 is further provided on the water storage structure 3, and the vent hole 13 is connected to the water storage cavity 14. The diameter of the vent hole 13 is 0.1-0.2 mm, ensuring that the collected mist beads can flow out through the water storage outlet 11 after the valve 12 is opened.

[0047] Since the water seal structure 2 is filled with water, and the water seal outlet 8 below the water seal structure 2 is lower than the cover plate 5, a negative pressure is formed at the through hole 6 of the cover plate 5, thereby driving the mist beads collected by the water collecting component 1 to quickly pass through the through hole 6 of the cover plate 5 and enter the water seal inner cavity 7. When the mist beads enter the water seal inner cavity 7, the volume of water is greater than the volume of the water seal inner cavity 7, and the concave surfaces of the water at the water seal outlet 8 and the through hole 6 of the cover plate 5 become gentle. The upward force generated by the sum of the interfacial pressure generated by the water at the cover plate 5 and the interfacial pressure generated by the water at the water seal outlet 8 is less than the pressure generated by the liquid column of the water in the water seal structure 2, so that the water in the water seal inner cavity 7 will Under the action of gravity, the water flows out along the water seal outlet 8 and enters the water storage structure 3. As the water flows out, when the volume of the water gradually approaches the volume of the water seal inner cavity 7, the curved surface of the water at the water seal outlet 8 and the water at the through hole 6 of the cover plate 5 returns to the concave initial position. The upward force generated by the sum of the interface pressure generated by the water at the cover plate 5 and the interface pressure generated by the water at the water seal outlet 8 is greater than the pressure generated by the liquid column of the water in the water seal structure 2. The water stops flowing out, and the water storage inlet 10 of the water storage structure 3 is covered by the water seal structure 2, thereby ensuring that the gathered fog beads will not be re-dissipated into the air due to evaporation, ensuring the unidirectional flow of the water collection process. When the water in the water storage structure 3 is almost full, the water is discharged through the water storage outlet 11.

[0048] The water collection device 100 of this embodiment mainly utilizes the inclined fog-facing surface of the spiral water collection component 1, which can drive the condensed fog beads to move downward all the time, and also enables the fog beads to sweep across each circle of the fog-facing surface along the way, without providing energy to remove the droplets. The sum of the interfacial pressure generated by the water at the cover plate 5 and the interfacial pressure generated by the water at the water seal outlet 8 of this embodiment is greater than the pressure of the water in the water seal inner cavity 7, ensuring that the water inside the water seal structure 2 will not flow out along the water seal outlet 8 below, so that the water seal structure 2 can ensure that the gathered fog beads pass smoothly and prevent the fog beads from evaporating and escaping into the air again. This embodiment mainly relies on the spiral water collection component 1 to collect water, which not only has a compact and simple structural design and low production cost, but also has the characteristics of no maintenance and low labor cost, and has a wide range of applications.

[0049] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
