Description

Technical Field

[0001] The invention relates to the field of cleaning equipment, and in particular to integrated equipment for air-water extraction, cleaning and recycling for photovoltaic panels. Background Art

[0002] The core working principle of photovoltaic panels is to efficiently convert light energy into electrical energy by capturing solar radiation. The cleanliness of the panel surface is directly related to the light transmittance and the photoelectric conversion efficiency of photovoltaic cells. Specifically, when sand, dust or other types of pollutants are deposited on the surface of photovoltaic panels, these impurities will form a light-shielding covering on the surface of the panel, effectively blocking the penetration of sunlight, thereby weakening the light intensity reaching the photovoltaic cells, resulting in a significant decline in the overall power generation efficiency.

[0003] In view of this, in order to ensure that the photovoltaic panels maintain an efficient and stable operating state, regular dust removal and cleaning operations are particularly critical. Water is an important material for photovoltaic panel dust removal. By flushing, photovoltaic panels can be quickly cleaned. However, photovoltaic panels are usually set up outdoors, and it is inconvenient to get water. Therefore, how to solve the problem of water shortage for outdoor photovoltaic panels is a problem that this solution needs to solve. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an integrated device for air water extraction, cleaning and recycling of photovoltaic panels.

The water entering the water collecting container is filtered through a filter membrane to prevent impurities from entering the water collecting area below. The filtered water can be transported out again through the outlet pipe to clean the photovoltaic panel, thereby achieving the purpose of recycling and reusing the water after cleaning the photovoltaic panel.

[0010] The metal-organic framework material body captures water from the air, and the capillary action and gravity of the superhydrophilic material collect the captured water, decoupling the water absorption and water collection processes.

[0012] Preferably, the metal organic framework material body has a plurality of protrusions distributed in a matrix, and the super hydrophilic material piece is a linear structure, which is S-shaped and penetrates between the protrusions, thereby increasing the contact area between the metal organic framework material body and the air and the super hydrophilic material piece.

[0013] Preferably, the super-hydrophilic material is a cetyltrimethylammonium chloride composite sodium polyacrylate antibacterial super-hydrophilic material, which improves the wettability and surface activity of the super-hydrophilic material, while exhibiting good antibacterial properties, and avoids contamination of the material during long-term use in an open environment.

[0014] Preferably, the air water intake unit is located in the water intake container, and an electric blade is provided at the upper port of the water intake container.

DETAILED DESCRIPTION

[0025] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0026] Example

[0027] like Figure 1As shown, the integrated equipment for air water extraction, cleaning and recycling for photovoltaic panels includes a cleaning unit, a water purification unit and an air water extraction unit.

[0028] The cleaning unit includes a water spray pipe 1 and a water collecting tank 2 . The water spray pipe 1 is arranged at the upper edge of the photovoltaic panel 3 , and the water collecting tank 2 is arranged at the lower edge of the photovoltaic panel 3 .

[0029] The water purification unit includes a water collection container 4 and a filter membrane 5 arranged on the upper part of the water collection container 4; the water collection container 4 below the filter membrane 5 is connected to the water shower pipe 1 through a water outlet pipe 6, and the water outlet pipe 6 is provided with a water pump, and the water collection container 4 above the filter membrane 5 is connected to the water collection tank 2 through a water inlet pipe 7;

[0030] Combination Figure 2 As shown, the water outlet end of the air water intake unit is connected to the water collecting container 4, and the air water intake unit includes a metal organic framework material body 8 (MOFs) and a super hydrophilic material piece 9.

[0031] The water in the water collecting container 4 is discharged from the shower pipe 1 and then rinses the surface of the photovoltaic panel 3. The water in the photovoltaic panel 3 flows downward to the water collecting tank 2, where the water is collected and then flows back to the water collecting container 4 through the water inlet pipe 7. The water entering the water collecting container 4 is filtered through the filter membrane 5 to prevent impurities from entering the water collecting area below. The filtered water can be transported out again through the water outlet pipe 6 to clean the photovoltaic panel 3, thereby achieving the purpose of recycling and reusing the water after cleaning the photovoltaic panel 3.

[0032] The metal organic framework material body 8 captures water in the air, and the capillary action and gravity of the super hydrophilic material piece 9 collect the captured water, decoupling the water absorption and water collection processes, achieving efficient air water collection in two steps, and collecting the water into the water collection container 4.

[0033] Given the remarkable characteristics of high porosity, large specific surface area and highly adjustable structure, the metal organic framework material 8 shows unique application potential in the field of air water extraction. Specifically, the metal organic framework material 8 exhibits excellent thermal stability and recycling ability, and by introducing hydrophilic functional groups, it greatly enhances its ability to capture water vapor, thereby effectively improving the overall efficiency of air water extraction and achieving the first step of water adsorption.

[0034] The super-hydrophilic material piece 9 is inserted into the metal organic framework material body 8, and a water collecting pipe 10 is provided at the end of the super-hydrophilic material piece 9, and the end of the water collecting pipe 10 is connected to the water collecting container 4. The super-hydrophilic material piece 9 inserted in the metal organic framework material body 8 can better extract the water in the metal organic framework material body 8, and then the water is concentrated and transported to the water collecting container 4 through the water collecting pipe 10.

[0035] The metal organic framework material body 8 has a plurality of protrusions distributed in a matrix, and the super hydrophilic material piece 9 is a linear structure, which is S-shaped and penetrates between the protrusions, thereby increasing the contact area between the metal organic framework material body 8 and the air and the super hydrophilic material piece 9.

[0036] The super-hydrophilic material 9 is a hexadecyltrimethylammonium chloride composite sodium polyacrylate antibacterial super-hydrophilic material. The wettability and surface activity of the super-hydrophilic material 9 are improved, and at the same time, good antibacterial properties are exhibited to prevent the material from being contaminated during long-term use in an open environment. In terms of structural characteristics, hydrophilic group distribution and water absorption mechanism, it exhibits more excellent hydrophilic properties than the metal organic framework material body 8. In addition, the composite material also has excellent antibacterial properties and can effectively improve water quality.

[0037] The superhydrophilic material piece 9 has outstanding rapid water absorption and long-lasting water retention capabilities, and can collect water from the metal organic framework material body 8. The material is applied to porous nanotextiles carefully woven from high specific surface area fibers. These fibers have a fine micron-level pore structure and show remarkable flexibility, and exhibit good capillary phenomena when in contact with water. Through the capillary effect, water can be rapidly transferred inside the porous nanotextiles, and under the coordinated guidance of gravity, the water is efficiently transported to the water collection bucket to achieve the second step of water collection. The metal organic framework material body 8 and the superhydrophilic material piece 9 decouple the water collection strategy and the release strategy to efficiently adsorb and collect water from the air.

[0038] The filter membrane 5 is made of polyvinylidene fluoride (PVDF) to achieve a more refined filtration treatment of the collected water (including air water, rainwater and recycled wastewater) to achieve water purification.

[0039] As shown in the figure, the air water intake unit is located in the water intake container 11, and the upper port of the water intake container 11 is provided with an electric vane 12. The electric vane 12 can be opened at night to facilitate the metal organic framework material body 8 to contact with the air to capture moisture in the air. During the hot daytime, the electric vane 12 is closed to reduce the evaporation of water in the water collection container 4.

[0040] The electric vane 12 includes a plurality of parallel strip plates, the two ends of which are rotated to match the upper port of the water collection container 11, and the motor drives the strip plates to rotate, and the strip plates are closed or opened by rotating the head and tail to meet or move the head and tail away. The rotation of multiple strip plates can well realize the opening and closing of the upper port of the water collection container 4, and takes up less space.

[0041] The invention comprises a timer electrically connected to the motor, and the timer is used to start or stop the motor operation at a fixed time. The motor can be started at a fixed time, which is more convenient.

[0042] The water in the water collecting container 4 is discharged from the shower pipe 1 and then rinses the surface of the photovoltaic panel 3. The water from the photovoltaic panel 3 flows downward through the coarse filter 13 to the water collecting tank 2, where the water is collected and then flows back to the water collecting container 4 through the water inlet pipe 7. The water entering the water collecting container 4 is filtered through the filter membrane 5 to prevent foreign particles from entering the water collecting area below. The filtered water can be transported out again through the outlet pipe 6 to clean the photovoltaic panel 3, thereby achieving the purpose of recycling and reusing the water after cleaning the photovoltaic panel 3.

[0043] The water collection tank 2 is provided with a coarse filter 13. It can achieve preliminary filtration of impurities on the photovoltaic panel 3, prevent large impurities from entering the water collection container 4, and prevent them from having a negative impact on the water collection system and subsequent air water intake operations. Whenever it rains, rainwater flows directly into the water collection container 4 through the water collection tank 2. This design allows rainwater to be fully collected, further enriching the water source for air water intake, and at the same time can naturally flush the coarse filter 13 to maintain its good filtering performance. After the cleaning operation, the water flows smoothly back to the water collection barrel through a non-enclosed water delivery channel, realizing dual-effect rainwater collection and wastewater recycling.

[0044] The water collecting tank 2 is inclined at an angle of 8-15 degrees relative to the horizontal plane, so that the collected water has sufficient flow power and is recycled through the water inlet pipe 7.

[0045] Advantages of the present invention:

[0046] This solution significantly improves the utilization rate of water by recycling the clean water used to clean the photovoltaic panel 3, and adopts multiple filtration to improve the cleanliness of water and avoid secondary pollution of the photovoltaic panel 3. The metal organic framework material body 8 captures water in the air, and the capillary action and gravity action of the super hydrophilic material part 9 collect the captured water, decoupling the water absorption and water collection processes, and realizing efficient air water collection in two steps. On the one hand, the clean water is reused repeatedly, and on the other hand, water is taken from the air, which can significantly improve the cleaning ability of the photovoltaic panel 3 and reduce the dependence on external water supply.

[0047] The metal organic framework material body 8 in the water collection device of the present invention plays a key role. These adsorbent materials have been carefully screened and developed, and have excellent adsorption properties, and can keenly capture water vapor molecules in the surrounding atmospheric environment. Its unique microstructure and chemical properties make the material surface have a strong affinity for water vapor, just like a sponge absorbing water, and can efficiently extract moisture from the air during periods of suitable humidity. This process not only depends on the characteristics of the adsorbent material itself, but also cleverly uses the microenvironmental changes generated when the photovoltaic panel 3 is working. Under sunlight, the surface temperature of the photovoltaic panel 3 rises rapidly, forming a significant temperature gradient with the surrounding environment, thereby causing local airflow disturbances. This microenvironmental change creates more favorable conditions for the accumulation of water vapor on the surface of the adsorbent material, accelerates the capture process of water vapor, and reserves sufficient water resources for subsequent cleaning operations.

[0048] As the amount of water absorbed by the adsorption material gradually increases, the super-hydrophilic material piece 9 in the device begins to work. The super-hydrophilic material piece 9 has special surface properties that can greatly reduce the contact angle between water and the material surface, making the water on its surface extremely fluid. Driven by the synergistic effect of capillary action and gravity, the water adsorbed on the surface of the material quickly gathers to form water droplets, and is continuously transmitted to the water collection bucket along the carefully designed water pipe path. This process fully realizes the automated water resource collection function without the need for human intervention, ensuring the efficiency and stability of the collection process.

[0049] The technical difficulty of efficiently and environmentally friendly water collection from the atmosphere has been successfully overcome, and deep integration with the operation of photovoltaic panels 3 has been achieved. The device not only significantly improves the efficiency of water collection, provides a reliable water source guarantee for the stable operation of photovoltaic panels 3, but also ensures the purity and availability of the collected water resources through a series of rigorous processing steps, effectively reducing the water consumption and operating costs of the photovoltaic industry during cleaning operations. It breaks the dependence of traditional photovoltaic applications on external water resources, allowing photovoltaic energy to be promoted and applied on a large scale and efficiently in deserts, arid and semi-arid areas, and urban areas with severe industrial pollution, making a positive contribution to promoting the development of clean photovoltaic panels 3.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
