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

[0034] Water surface shading structures can float on water to block light, such as sunlight, reducing the amount of light reaching the water and thus reducing evaporation. However, these structures are prone to damage and are not reliable enough.

[0035] The following analysis explains why water surface shading structures in related technologies are prone to damage. The analysis process and conclusions are part of the inventiveness of this application.

[0036] When a water surface shading structure floats on the water, it is susceptible to significant external loads, such as wind and wave loads, collision loads between multiple floating water surface shading structures, and loads generated during the thermal expansion or contraction of the structure. In related technologies, the water surface shading structure is a closed, hollow structure enclosed by thin walls, which can float on water. However, thin walls often struggle to withstand the aforementioned external loads, easily leading to dents or even leaks, resulting in poor reliability.

[0037] Please refer to Figure 1 and Figure 2The water surface shading structure can float on a water surface 01. The water surface 01 can be a lake surface or a reservoir surface, and the reservoir can be a drinking water reservoir, an irrigation reservoir, a pumped storage power station reservoir, or a hydropower station reservoir.

[0038] Please refer to Figure 1 and Figure 2 The water surface shading structure provided in the embodiments of the present application includes a shell 1, a filler 2, and a counterweight 3. The shell 1 encloses a closed containing cavity 11; the filler 2 is in a granular form and has a density less than that of the shell 1, the filler 2 is filled in the containing cavity 11, and the filler 2 encloses an installation cavity; and the counterweight 3 cooperates with the installation cavity to be fixed in the containing cavity 11.

[0039] Please refer to Figure 1 and Figure 2 The water surface shading structure provided in the embodiments of the present application is filled with the filler 2 in the containing cavity 11, so that the inner surface of the shell 1 can be stably supported by the filler 2. The filler 2 can better share the external load, such as the wind and wave load and the collision load between multiple water surface shading structures, thereby improving the stress condition of the shell 1 and preventing the shell 1 from being easily dented or damaged, and the reliability of the shell 1 is improved. The filler 2 is a solid and has a thermal conductivity greater than that of air. The filler 2 can better absorb the heat or cold of the shell 1, thereby reducing the degree of thermal expansion and contraction of the shell 1. The filler 2 has strong weather resistance, strong adaptability to high temperature, low temperature, and freeze-thaw cycles, and high reliability. The density of the filler 2 is less than that of the shell 1, so that the average density of the water surface shading structure is small, and the water surface shading structure can meet the requirement of floating on the water surface 01 to block sunlight. Therefore, the water surface shading structure provided in the embodiments of the present application can improve the reliability of the water surface shading structure.

[0040] Moreover, the inner surface of the shell 1 can be stably supported by the filler 2, and the stress condition of the shell 1 is improved, so that the thickness of the shell 1 can be set to be relatively thin, thereby reducing the cost of the water surface shading structure.

[0041] In addition, the counterweight 3 cooperates with the installation cavity enclosed by the filler 2, so that the counterweight 3 can be easily fixed at a target position in the containing cavity 11. The filler 2 is used to improve the stress of the shell 1 and to fix the counterweight 3, and the filler 2 is fully utilized, thereby improving the compactness of the structure.

[0042] In addition, the filler 2 is in a granular form. In this way, the process of injecting the filler 2 into the accommodating cavity 11 is more convenient, and the filler 2 is more easily hindered from entering the accommodating cavity 11. Moreover, the position of the weight 3 in the accommodating cavity 11 can be conveniently adjusted, which is beneficial to improve the convenience of processing and manufacturing the water surface shading structure.

[0043] Please refer to Figure 1 and Figure 2 , it should be explained that in the embodiment of the present application, the inner surface of the shell 1 is the side of the shell 1 close to the accommodating cavity 11, and the outer surface of the shell 1 is the side of the shell 1 away from the accommodating cavity 11.

[0044] Please refer to Figure 1 and Figure 2 , it should be explained that in the embodiment of the present application, when the water surface shading structure floats on the water surface, Figure 2 the direction perpendicular to the paper in the figure is the vertical direction a.

[0045] Please refer to Figure 1 and Figure 2 , it should be explained that in the embodiment of the present application, the weight 3 has the same meaning as that commonly understood by those skilled in the art, the density of the weight 3 is greater than the density of the shell 1 and the density of the filler 2, and by arranging the weight 3, the position of the center of gravity of the water surface shading structure can be more easily adjusted, so that when the water surface shading structure floats on the water surface 01, the center of gravity is lower, and it is not easy to roll up and down greatly, causing the end of the water surface shading structure originally facing the light, i.e. the upper end, to contact the water body, and aggravating the evaporation of the water body.

[0046] Please refer to Figure 1 and Figure 2 , in the embodiment of the present application, the shading part can be arranged on at least one of the shell 1, the filler 2 and the weight 3. In some embodiments of the present application, the shading part is a shading layer arranged on the outer surface of the shell 1, the thickness direction of the shading layer can be the same as the thickness direction of the shell 1, and the shading layer can completely shield the outer surface of the shell 1. In this way, the shading part is more convenient to manufacture. In some embodiments of the present application, the shading layer can be formed of a shading material coated on the outer surface of the shell 1. In this way, the shading part is more convenient to manufacture. In some embodiments of the present application, the material of the shading material can include ultraviolet absorbers, such as salicylate ultraviolet absorbers, benzophenone ultraviolet absorbers, benzotriazole ultraviolet absorbers, substituted acrylonitrile ultraviolet absorbers, and triazine ultraviolet absorbers. In this way, the shading effect is better.

[0047] Please refer to Figure 1 and Figure 2In some embodiments of the present application, the shell 1 is injection molded, and the injection material can include light shielding material such as ultraviolet absorber and the like. In this way, the light shielding part is at least a part of the shell 1, and the light shielding part is convenient to manufacture and reliable.

[0048] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the material for manufacturing the shell 1 can include at least one of plastic material such as high density polyethylene (HDPE) and polypropylene. In this way, the cost is low, and the strength of the shell 1 is high.

[0049] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the material for manufacturing the shell 1 can include at least one of anti-aging agent and antioxidant. In this way, it is beneficial to improve the reliability of the shell 1. The person can determine the specific shell 1 material, shell 1 thickness, and shell 1 volume and the like parameters through weather resistance, mechanics, aging, toxicity and the like tests.

[0050] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the counterweight 3 is spaced apart from the inner surface of the shell 1. In this structure, the filler 2 isolates the counterweight 3 from the inner surface of the shell 1, so that the counterweight 3 is not easy to damage the shell 1, which is beneficial to improve the reliability of the water surface light shielding structure, and the degree of freedom of the selection of the material of the counterweight 3 is greater. For example, the counterweight 3 can be selected from stone, brick and the like, which is beneficial to save cost.

[0051] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the filler 2 is made of foamed material. In this way, the cost of the filler 2 is low, the strength is high, and the density is small, which is beneficial to make the water surface light shielding structure have high reliability, and is beneficial to make the average density of the water surface light shielding structure small, so that the water surface light shielding structure can meet the demand of floating on the water surface 01 to shield sunlight. Moreover, the foamed material has high flexibility, which can well buffer the external load, and is beneficial to improve the reliability of the water surface light shielding structure. In the embodiments of the present application, the foamed material can be various, such as foamed plastic, foamed rubber or foamed resin and the like. The foamed plastic can be made of plastic, catalyst and foaming agent through physical foaming and crosslinking foaming. In some embodiments of the present application, the material for manufacturing the filler 2 can include at least one of polyethylene foamed plastic and polyurethane foamed plastic.

[0052] Please refer to Figure 1 and Figure 2In some embodiments of the present application, the accommodating cavity 11 is spherical; along the radial direction of the accommodating cavity 11, the distance between the spherical center of the accommodating cavity 11 and the center of mass of the counterweight 3 is greater than or equal to one-half of the radius of the accommodating cavity 11 and less than or equal to two-thirds of the radius of the accommodating cavity 11. In the embodiments of the present application, the distance between the spherical center of the accommodating cavity 11 and the center of mass of the counterweight 3 can refer to the first distance b in the figure. With this structure, by making the first distance b greater than one-half of the radius of the accommodating cavity 11, it is beneficial to make the center of gravity lower when the water surface shading structure floats on the water surface 01, so that it is not easy to roll up and down to a large extent, causing the end of the water surface shading structure originally facing the light, i.e., the upper end, to roll to a position in contact with the water body, aggravating the evaporation of the water body. In addition, by making the first distance b less than or equal to two-thirds of the radius of the accommodating cavity 11, the center of gravity is not too low when the water surface shading structure floats on the water surface 01, so that the length of the water surface shading structure sinking into the water body is not too large, thereby affecting the shading effect of the water surface shading structure. It can be understood that the cross-sectional profile of the water surface shading structure passing through the spherical center of the accommodating cavity 11 is larger, so that the cross section of the water surface shading structure passing through the spherical center of the accommodating cavity 11 is close to the water surface 01, which can make the shading effect of the water surface shading structure better.

[0053] In the embodiments of the present application, the personnel can adjust the mass, position, and volume of the counterweight 3, the material and density of the filler 2, the density, wall thickness, and volume of the shell 1, and the volume and density of the supporting block 4, and other parameters according to external environmental factors such as the density of the water body, the wind direction and wind force, etc., through orthogonal contrast test, so that the water surface 01 is close to the spherical center of the accommodating cavity 11, to improve the shading effect of the water surface shading structure. In addition, by adjusting the above-mentioned parameters, a water surface shading structure with lower cost and higher reliability can also be obtained more conveniently.

[0054] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the outer surface of the shell 1 is spherical, and the spherical center of the outer surface of the shell 1 is the same as the spherical center of the accommodating cavity 11. With this structure, on the one hand, the cross-sectional profile of the water surface shading structure passing through the spherical center of the accommodating cavity 11 is larger, which is beneficial to improve the shading effect; on the other hand, it is beneficial to make the shell 1 more stably supported on the water surface 01, and not easy to roll up and down to a large extent.

[0055] Please refer to Figure 1 and Figure 2In some embodiments of this application, the shell 1 further includes a support block 4, which is disposed on the outer surface of the shell 1 and protrudes radially outward relative to the outer surface of the shell 1 along the receiving cavity 11. The center of the receiving cavity 11 and the counterweight 3 are arranged along a first direction, and the center of the receiving cavity 11 and the support block 4 are arranged along a second direction, which is perpendicular to the first direction. With this structural form, the support block 4 is provided on the outer surface of the shell 1, which can strengthen the shell 1 and help improve the stress condition of the shell 1. By making the second direction perpendicular to the first direction, when the water surface shading structure floats on the water surface 01, the maximum horizontal section of the shell 1 passes through the support block 4. That is, the support block 4 is located on the water surface shading structure and is more likely to collide with other water surface shading structures. Relative to the outer surface of the shell 1, the support block 4 is more likely to come into contact with other water surface shading structures, reducing the possibility of the outer surface of the shell 1 directly contacting other water surface shading structures, which helps improve the stress condition of the shell 1.

[0056] Please refer to Figure 3 and Figure 4 Furthermore, the support block 4 can also increase the support between the water surface shading structure and the water surface 01, as well as other water surface shading structures, which helps to reduce the up-and-down tumbling of the water surface shading structure and its tumbling along the water surface 01, thus improving the shading effect.

[0057] Please refer to Figure 3 and Figure 4 In some embodiments of this application, the length of the water surface shading structure is less than the length of the shell 1 along the circumferential direction of the outer surface of the shell 1. Thus, when the water surface shading structure floats on the water surface 01, the support blocks 4 of two adjacent water surface shading structures can be supported together along the circumferential direction of the outer surface of the shell 1, which helps to reduce the movement of the water surface shading structure relative to the water surface 01 and improves the shading effect of the water surface shading structure. Of course, in some embodiments of this application, the length of the water surface shading structure can also be equal to the length of the shell 1. In this case, the water surface shading structure extends along the outer surface of the shell 1 to form a closed ring structure, which helps to improve the stress situation of the shell 1.

[0058] Please refer to Figure 3 and Figure 4 In some embodiments of this application, the length of the protruding structure in the first and second directions can be less than the radius of the outer surface of the housing 1. This helps to save materials and reduce costs.

[0059] Please refer to Figure 3 and Figure 4In some embodiments of the present application, the number of support blocks 4 is at least two, and the at least two support blocks 4 are arranged along the circumference of the outer surface of the shell 1. In this way, the support blocks 4 can strengthen the larger area of the shell 1 along the circumference of the outer surface of the shell 1, thereby improving the reliability of the shell 1.

[0060] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the support blocks 4 can be integrally formed with the shell 1. In this way, the support blocks 4 are more convenient to manufacture, and the combination of the support blocks 4 and the shell 1 is more compact and less likely to separate, thereby improving the reliability.

[0061] Please refer to Figure 5 , Figure 1 and Figure 2 The present application also provides a preparation method of a water surface shading structure, the water surface shading structure comprising a shell 1, a filler 2, and a counterweight 3, the shell 1 comprising a first shell part and a second shell part, the first shell part having a first opening, the filler 2 being in a granular form and having a density less than that of the shell 1; the preparation method of the water surface shading structure comprising:

[0062] S1, placing the filler 2 into the first shell part through the first opening;

[0063] S2, placing the counterweight 3 into the first shell part through the first opening, and cooperating the counterweight 3 with the mounting cavity formed by the filler 2;

[0064] S3, blocking the first opening with the second shell part, so that the first shell part and the second shell part jointly form a closed containing cavity 11.

[0065] In this way, the shell 1 comprises the first shell part and the second shell part, and during the manufacturing of the water surface shading structure, the filler 2 and the counterweight 3 are first filled into the first shell part, and then the second shell part blocks the first shell part, thereby making the manufacturing of the water surface shading structure more convenient.

[0066] Please refer to Figure 5 , Figure 1 and Figure 2 In some embodiments of the present application, the first shell part and the second shell part are thermally fused. In this way, the stability of the connection between the first shell part and the second shell part is improved, the sealing property of the containing cavity 11 is improved, water is less likely to penetrate into the containing cavity 11, and the reliability of the water surface shading structure is improved.

[0067] Please refer to Figure 5 , Figure 1 and Figure 2In some embodiments of this application, the first shell and the second shell have the same shape. This facilitates the processing and manufacturing of the first and second shells, which can be made from the same mold, thus improving the production efficiency of the water surface shading structure. In some embodiments of this application, before the second shell seals the first opening to form a closed receiving cavity 11 together with the first and second shells, the method for preparing the water surface shading structure further includes placing the filler 2 into the second shell through the second opening. This improves the filling rate of the receiving cavity 11 by the filler 2 and enhances the reliability of the water surface shading structure.

[0068] Please refer to Figure 5 , Figure 1 and Figure 2 For example, in some embodiments of this application, the receiving cavity 11 is spherical; the outer surface of the shell 1 is spherical, and the center of the sphere on the outer surface of the shell 1 is the same as the center of the sphere in the receiving cavity 11. The inner and outer surfaces of the first shell portion can be concentric and matched hemispheres, and the inner and outer surfaces of the second shell portion can be concentric and matched hemispheres. The inner surfaces of the first and second shell portions have the same radius, and the outer surfaces of the first and second shell portions have the same radius. This facilitates the processing and manufacturing of the first and second shell portions, which can be made from the same mold, thus improving the production efficiency of the water surface light-shielding structure.

[0069] Please refer to Figure 5 , Figure 3 and Figure 4 Based on this, in some embodiments of this application, the housing 1 further includes a support block 4, and the first housing portion and the second housing portion can be arranged opposite each other along a first direction or a second direction. In this way, when the first housing portion and the second housing portion are arranged opposite each other along the first direction, each support block 4 is evenly divided into two identical first sub-support blocks by the interface between the first housing portion and the second housing portion. The two first sub-support blocks can be made using the same mold, which improves the ease of manufacturing the support block 4. When the first housing portion and the second housing portion are arranged opposite each other along the second direction, the interface between the first housing portion and the second housing portion does not need to pass through the support block 4, and the support blocks 4 on the first housing portion and the support blocks 4 on the second housing portion can be made using the same mold, which improves the ease of manufacturing the support block 4. When the first housing portion and the second housing portion are arranged opposite each other along the second direction, the interface between the first housing portion and the second housing portion can also divide the support block 4 into two identical second sub-support blocks. The two second sub-support blocks can be made using the same mold, which improves the ease of manufacturing the support block 4.

[0070] Please refer to Figure 3 and Figure 4The water surface shading structure laying method provided by the embodiment of the present application is applied to the water surface shading structure provided by the embodiment of the present application, and comprises: laying a plurality of water surface shading structures on the water surface 01, and the sum of the maximum cross-sectional areas of the plurality of water surface shading structures is greater than or equal to the area of the water surface 01. In this way, the plurality of water surface shading structures can sufficiently cover the water surface 01, and the number of the water surface shading structures is not too large, which is beneficial to balancing the cost and the shading effect.

[0071] Please refer to ​ and ​ In some embodiments of the present application, before the plurality of water surface shading structures are laid on the water surface 01, the water surface shading structure laying method further comprises arranging the fence 02 extending along the contour of the water surface 01. In this way, after the plurality of water surface shading structures are laid on the water surface 01, the fence 02 can limit the water surface shading structures on the water surface 01, and the water surface shading structures are not easy to fall onto the shore under the action of external loads such as wind and wave loads, which is beneficial to improving the shading effect.
