[0004] This invention provides a self-cleaning nano-coating condensation device based on photovoltaic modules, comprising: Support components are fixedly placed on the ground; The photovoltaic panel is fixedly mounted at an angle on the top of the support assembly, and its surface is coated with a self-cleaning nano-coating. A water-collecting component is located below the lower end of the photovoltaic panel and is fixedly connected to the support component. It is used to collect dew that condenses on the surface of the photovoltaic panel and flows down. A water collection component is disposed below both ends of the water receiving component and is fixedly connected to the support component. It is used to collect the dew received by the water receiving component and filter it. The dripping components are evenly distributed at the bottom of the water receiving components. When the dripping components are closed, the dew received by the water receiving components flows into the water collecting components. When the dripping components are open, the dew received by the water receiving components flows into the ground.

[0005] Furthermore, the support assembly includes several bases buried in the ground, with vertical rods fixedly installed on the top of each base. Adjacent vertical rods are fixedly connected by horizontal rods. Inclined frame plates are fixedly connected to the tops of the vertical rods, and diagonal braces are fixedly installed between the tops of the vertical rods and the frame plates on both sides.

[0006] Furthermore, the surfaces of the vertical rods, horizontal rods, frame plates, and diagonal braces are all coated with a self-cleaning nano-coating.

[0007] Furthermore, the water receiving assembly includes a water receiving trough disposed below the lower end of the photovoltaic panel. The length of the water receiving trough is not less than the length of the photovoltaic panel. Several connecting plates are fixedly disposed on one side of the water receiving trough, and the connecting plates are fixedly connected to the support assembly by screws.

[0008] Furthermore, the water collection assembly includes trays respectively disposed below both ends of the water receiving tank. The trays are fixedly connected to the support assembly via connecting frames. The top of the tray is provided with a groove, on which a water collection bucket is placed.

Each end of the water receiving groove has an installation groove, and a baffle is detachably inserted into the installation groove to seal both ends of the water receiving groove.

[0010] Furthermore, this invention also provides an effect test for the self-cleaning nano-coating condensation device based on photovoltaic modules as described above, including the following steps: 1) A control device is set up on one side of the condensation device. The only difference between the control device and the condensation device is that the photovoltaic panel of the control device is not coated with a self-cleaning nano-coating. 2) Weigh the dew collected in the water collection components of the dew collection device and the control device in the early morning, and record the weight values ​​respectively; 3) Take two towels with a weight difference of less than 0.1g, and wipe the photovoltaic glass of the photovoltaic panel of the condensation device and the control device with the same force.

[0011] Compared with the prior art, the beneficial effects of the present invention are: (1) The condensation device of the present invention is provided with a water receiving component, a water collecting component and a water dripping component. By spraying a self-cleaning nano-coating on the surface of the photovoltaic panel, its "super-hydrophilicity" is improved, so that the dew condensed on the surface of the photovoltaic panel flows down quickly.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please refer to Figures 1-3 The present invention provides a self-cleaning nano-coating condensation device based on a photovoltaic module, comprising: Support component 1 is fixedly placed on the ground; Photovoltaic panel 2 is fixedly mounted at an angle on top of support component 1, and its surface is coated with a self-cleaning nano-coating. Water receiving component 3 is located below the lower end of photovoltaic panel 2 and is fixedly connected to support component 1. It is used to receive dew that flows down after condensation on the surface of photovoltaic panel 2. The water collection component 4 is located below both ends of the water receiving component 3 and is fixedly connected to the support component 1. It is used to collect the dew received by the water receiving component 3 and filter it. The dripping components 5 are evenly distributed at the bottom of the water receiving components 3. When the dripping components 5 are closed, the dew received by the water receiving components 3 flows into the water collecting components 4. When the dripping components 5 are open, the dew received by the water receiving components 3 flows into the ground.

[0019] In this embodiment, a self-cleaning nano-coating is sprayed onto the surface of the photovoltaic panel 2, which improves the "superhydrophilicity" of the photovoltaic panel 2. This allows the dew condensed on the surface of the photovoltaic panel 2 to flow down quickly, greatly reducing the amount of dew left on the surface of the photovoltaic panel 2. After being received by the water receiving component 3, the dew can be collected by the water collection component 4, which increases the effective amount of dew collected to alleviate water shortage problems in water-scarce areas. Alternatively, the dew can be dripped directly onto the ground by the dripping component 5 to improve soil and water conservation and improve the environment.

[0020] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the support assembly 1 includes several bases 11 buried in the ground. A vertical rod 12 is fixedly installed on the top of the base 11. Adjacent vertical rods 12 are fixedly connected by a horizontal rod 13. An inclined frame plate 14 is fixedly connected to the top of several vertical rods 12. Diagonal bracing rods 15 are fixedly installed on both sides of the top of the vertical rod 12 and the frame plate 14, respectively.

[0021] In this embodiment, the photovoltaic panel 2 is supported by a base 11, a vertical rod 12, a horizontal rod 13, a frame plate 14, and a diagonal brace 15. The structure is stable and ensures the safety of the photovoltaic panel 2.

[0022] In a preferred embodiment, the surfaces of the vertical rod 12, horizontal rod 13, frame plate 14 and diagonal brace 15 are all coated with a self-cleaning nano-coating, which allows the dew condensed on the support component 1 to flow down quickly and enter the ground, avoiding direct evaporation while remaining on the support component 1, thus improving the soil and water conservation effect.

[0023] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the water receiving component 3 includes a water receiving trough 31 located below the lower end of the photovoltaic panel 2. The length of the water receiving trough 31 is not less than the length of the photovoltaic panel 2. Several connecting plates 32 are fixedly installed on one side of the water receiving trough 31. The connecting plates 32 are fixedly connected to the support component 1 by screws 33.

[0024] In this embodiment, the water collection trough 31 is placed below the lower end of the photovoltaic panel 2 by the connecting plate 32. The dew condensed on the surface of the photovoltaic panel 2 flows to the lower end of the photovoltaic panel 2 under the action of gravity and flows into the water collection trough 31, resulting in good dew collection effect.

[0025] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, the water collection assembly 4 includes trays 41 respectively disposed below both ends of the water receiving tank 31. The trays 41 are fixedly connected to the support assembly 1 through the connecting frame 42. The top of the trays 41 is provided with a groove, on which a water collection bucket 43 is placed. The water collection bucket 43 is rotatably connected to a handle 44. The top of the water collection bucket 43 is provided with a first cylinder 45. The bottom end of the first cylinder 45 is provided with a first variable diameter section 46 that is inserted into the water collection bucket 43. The first cylinder 45 is provided with a first filter plate 47, which is densely covered with first filter holes 48. The top of the first cylinder 45 is provided with a second cylinder 49. The bottom end of the second cylinder 49 is provided with a second variable diameter section 410 that is inserted into the first cylinder 45. The second cylinder 49 is provided with a second filter plate 411, which is densely covered with second filter holes 412. The diameter of the first filter holes 48 is smaller than the diameter of the second filter holes 412.

[0026] In this embodiment, the dew flowing from both ends of the water receiving tank 31 is filtered sequentially through the second filter plate 411 and the first filter plate 47 before entering the water collection tank 43 for collection. Filter media can be filled into the first cylinder 45 and the second cylinder 49 as needed, or the number of cylinders can be increased to improve the filtration effect through multiple filtrations. The collected dew is further processed according to subsequent application needs before reuse, thereby alleviating water pressure.

[0027] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the dripping assembly 5 includes dripping pipes 51. Several dripping pipes 51 are connected at equal intervals along the length of the bottom of the water receiving tank 31. The bottom end of each dripping pipe 51 is threaded with a sealing cap 52. A sealing ring is embedded in the sealing cap 52. The two ends of the water receiving tank 31 are respectively provided with installation grooves. A baffle 53 can be detachably inserted into the installation groove for sealing the two ends of the water receiving tank 31.

[0028] In this embodiment, the state of the dripping component 5 is adjusted according to the different needs of dew. When collecting dew, the bottom end of each dripping pipe 51 is screwed with a sealing cap 52 and the baffle 53 is pulled out so that the collected dew flows out through the water receiving tank 31 and enters the collection component 4 for collection. When used for soil and water conservation, unscrew the sealing cap 52 and insert baffles 53 into both ends of the water collection trough 31, so that the dew collected in the water collection trough 31 flows directly out through each drip pipe 51 and drips into the ground. The setting of the drip component 5 improves the applicability of the condensation device.

[0029] Furthermore, embodiments of the present invention also provide an effect test for the self-cleaning nano-coating condensation device based on photovoltaic modules as described above, including the following steps: 1) A control device is set up on one side of the condensation device. The only difference between the control device and the condensation device is that the photovoltaic panel 2 is not coated with a self-cleaning nano-coating. 2) Weigh the dew collected in the water collection components 4 of the dew collection device and the control device in the early morning, and record the weight values ​​respectively; 3) Take two towels with a weight difference of less than 0.1g, and wipe the photovoltaic glass of the photovoltaic panel 2 of the condensation device and the control device with the same force. Weigh the towels after wiping and record the weight difference between the two towels before and after wiping. 4) Take two paper towels with good absorbency and a weight difference of less than 0.1g, and wipe the frame of the photovoltaic panel 2 of the condensation device and the control device with the same force. Weigh the paper towels after wiping and record the weight difference between the two paper towels before and after wiping. 5) The effect of the condensation device can be intuitively evaluated by using the weight parameters recorded in steps 2), 3), and 4).

[0030] In this embodiment, the morphology and fluidity of water droplets on the surfaces of the control device and the condensation device were observed by utilizing the natural dew in the early morning.

[0031] Condensation device: There are no obvious water droplets on the surface, a uniform water film is formed and flows downwards quickly, and water droplets "drip down in streams" at the edge.

[0032] Control device: Water droplets on the surface "gather into beads" and have no continuous flow, while water droplets at the edge "drop sporadically and slowly".

[0033] Table 1 shows a comparison of the data from the effectiveness test:

[0034] As shown in Table 1, the self-cleaning nano-coating significantly enhances the "superhydrophilicity" of photovoltaic panel 2, making dew flow more easily. While the amount of dew absorbed on the photovoltaic glass did not differ significantly, the dew collection amount of the coated condensation device was approximately 1.9 times that of the uncoated control device (141.3g / 73.9g), indicating that the self-cleaning nano-coating strengthens the aggregation and guidance of dew, effectively increasing the amount of dew collected.

[0035] The dew absorption of the frame of the coated photovoltaic panel 2 is about 2.4 times that of the frame of the uncoated photovoltaic panel 2 (7.9g / 3.3g). Moreover, the former shows a "continuous water film flowing down rapidly", while the latter shows "water droplets gathering and dripping slowly", indicating that the dew condensation effect is significantly improved after the self-cleaning nano-coating is sprayed on the frame.

[0036] By comparing the water collection and surface dew conditions of the two sets of devices, the condensation effect of the condensation device of this application can be intuitively obtained, providing a reliable data basis for its application layout.

[0037] In the description of this specification, the terms "connection," "installation," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
