[0002] Seawater desalination has become an important way to obtain fresh water. Traditional seawater desalination technologies (such as reverse osmosis) have high energy consumption. With the proposal of the "carbon peak" and "carbon neutralization" targets, it is imperative to further reduce energy consumption. Solar seawater desalination converts clean, efficient, and abundant solar energy into heat energy, promotes water evaporation, and thus obtains fresh water, which is one of the important ways to solve the current fresh water problem.

[0003] The existing solar seawater desalination devices generally have the problems of large size, complex structure, inconvenience to carry, etc. They cannot be conveniently stored and carried, the operation is relatively cumbersome, and the efficiency of seawater desalination is affected. Therefore, an umbrella type light-heat conversion seawater desalination device needs to be designed to solve the above problems. UTILITY MODEL CONTENTS

Under the light, it is heated and evaporates to produce steam. The steam rises and condenses into water droplets after contacting the transparent curved surface. The water droplets flow along the curved surface to the edge freshwater collection chamber. Then, the freshwater collection chamber collects the freshwater into the collection bucket through the water guide pipe. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please refer to Figures 1-5 As shown, this utility model provides an umbrella-type photothermal conversion seawater desalination device, including a main pole 1. A collection component for collecting fresh water by photothermal conversion is installed on the outer side of the main pole 1 near the middle and upper part. Multiple sets of umbrella ribs arranged in a circle to support the umbrella surface 2 are installed on the outer side of the main pole 1. An installation cavity 3 is opened on the inner side of the main pole 1 near the middle and upper part. A locking component for supporting the collection component and the support component is installed on the inner side of the installation cavity 3.

[0024] The umbrella ribs can support the umbrella surface 2 for opening or closing and storage, and the locking mechanism can support and lock the umbrella ribs for opening or closing and unlocking. The umbrella surface 2 is opened and placed on the sea surface, and the collecting mechanism collects fresh water through photothermal conversion, thereby improving the efficiency and convenience of seawater desalination.

[0025] Specifically, the collection component includes a fixing ring 4 that is slidably installed on the outside of the main rod 1. A photothermal conversion membrane 5 is fixedly installed on the outside of the fixing ring 4. A seawater desalination chamber 6 is opened between the photothermal conversion membrane 5 and the umbrella surface 2. A freshwater collection chamber 7 is opened at the edge of the photothermal conversion membrane 5 and the umbrella surface 2. Multiple water guide pipes 8 arranged in a circle are connected to the bottom of the freshwater collection chamber 7. A water collection bucket 9 is screwed on the outside of the water guide pipe 8 and near one end. A one-way valve is fixedly installed on the inside of the water guide pipe 8 and near one end. The bottom layer of the photothermal conversion membrane 5 is a hydrophilic layer, and the upper layer of the photothermal conversion membrane 5 is a hydrophobic Janus-type structure.

[0026] Among them, the umbrella surface 2 is made of an arc-shaped transparent material, and the connection between the photothermal conversion membrane 5 and the main rod 1 is a lightweight block or airbag to ensure that the device floats on the water surface. At the same time, the connecting block is higher than the photothermal conversion membrane 5 to prevent water from flowing back into the seawater desalination chamber 6. When the umbrella surface 2 is opened, the photothermal conversion membrane 5 is laid flat and placed on the water surface. Due to the role of the floating block (airbag) and the Janus structure, it is a special structure composed of two or more materials with different physical properties. The characteristics of the Janus structure are mainly reflected in its asymmetry. This asymmetry can manifest in several aspects, including electrical properties, polarity, and hydrophilicity / hydrophobicity. For example, Janus colloidal particles can be designed to have different hydrophilicity / hydrophobicity in their two different regions, thereby reducing the interfacial tension between different phases. In addition, the Janus structure can also respond specifically to external stimuli (such as light and heat), exhibiting photothermal effects, color adjustment, and other functions. It can float on the water surface to perform photothermal conversion for seawater desalination. The photothermal conversion membrane 5 is in direct contact with the water surface. Light shines through the transparent umbrella surface 2 onto the photothermal conversion membrane 5. Under the illumination, the membrane is heated and evaporates to produce steam. The steam rises and condenses into water droplets after contacting the transparent arc surface. The water droplets flow along the arc surface to the edge freshwater collection chamber 7. Then, the freshwater collection chamber 7 collects the freshwater into the water collection tank 9 through the water guide pipe 8.

[0027] More specifically, the umbrella ribs include a fixed frame 10 arranged circumferentially at the edge of the end of the main pole 1. The fixed frame 10 is hinged to the inner side of the umbrella rib pole 11. The umbrella rib pole 11 is hinged to one side of the umbrella rib pole 11. A sliding ring 13 is slidably installed on the outer side of the main pole 1 and above the fixed ring 4. The sliding ring 13 is hinged to the support rod 12. The locking component includes an elastic piece 14 fixedly installed at the bottom of the mounting cavity 3. Locking blocks 15 are fixedly connected to both ends of the elastic piece 14. A fixed plate 16 is fixedly connected to the inner side of the mounting cavity 3 and in the middle of the elastic piece 14. An elastic frame 17 is fixedly connected to both sides of the fixed plate 16. A spring piece 18 is fixedly installed on the inner side of the elastic frame 17. The elastic frame 17 is fixedly connected to the fixed plate 16 and the elastic piece 14 on both sides. The locking blocks 15 are slidably connected to the mounting cavity 3.

[0028] Furthermore, the sliding ring 13 can drive the umbrella rib rod 11 to rotate hingedly via the support rod 12, so that one end of the umbrella rib rod 11 can rotate hingedly within the fixing frame 10. At the same time, the support rod 12 can rotate hingedly on one side of the umbrella frame. The fixing ring 4 can drive the sliding ring 13 to slide on the outside of the column rod. The elastic piece 14 in the mounting cavity 3 can push the locking block 15 out of the mounting cavity 3, so that the two locking blocks 15 can lock and fix or unlock and slide the fixing ring 4. The spring piece 18 can support the elastic frame 17 to increase the strength of the elastic frame 17 supporting the end of the elastic piece 14 and improve the stability of the fixed sliding ring 13 and the fixing ring 4.

[0029] Working principle: First, the fixed ring 4 and the sliding ring 13 slide on the outside of the main rod 1. Then, the elastic plate 14 in the mounting cavity 3 pushes the locking block 15 out of the mounting cavity 3. At this time, the two locking blocks 15 lock and fix the fixed ring 4. At the same time, the spring plate 18 supports the elastic frame 17, and then the elastic frame 17 supports the elastic plate 14.

[0030] At this time, the umbrella surface 2 is opened, the photothermal conversion membrane 5 is laid flat and placed on the water surface. The photothermal conversion membrane 5 is in direct contact with the water surface. The light shines through the transparent umbrella surface 2 onto the photothermal conversion membrane 5. Under the light, it is heated and evaporates to produce steam. The steam rises and condenses into water droplets after contacting the transparent curved surface. The water droplets flow along the curved surface to the edge freshwater collection chamber 7. Then, the freshwater collection chamber 7 collects the freshwater into the water collection bucket 9 through the water guide pipe 8.

[0031] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
