[0027] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be completely conveyed to those skilled in the art.

[0028] Water surface evaporation refers to the process in which water on the water surface is converted into water vapor due to heat and then lost to the atmosphere. In a reservoir, water surface evaporation has various impacts on the environment and water resource management. In arid or hot regions, evaporation losses may lead to a reduction in the water storage capacity of the reservoir, affecting water supply and irrigation; as the water volume decreases, salts and other dissolved substances in the reservoir may concentrate, resulting in a decline in water quality, which may affect the safety of drinking water and the quality of agricultural irrigation in areas relying on reservoir water supply; the water level changes in the reservoir will affect the surrounding ecosystem, including aquatic organisms and terrestrial organisms relying on the reservoir water area. A decrease in the water level may lead to a reduction in the wetland area, affecting biodiversity; for areas relying on the reservoir for hydropower generation, the reduction in water volume caused by evaporation may affect the power generation efficiency and thus affect the energy supply.

[0029] The anti - evaporation floating ball is a device specifically designed to reduce evaporation losses on the water surface. It is usually made of lightweight and durable materials such as plastics or foams, and is designed in a spherical or similar shape so as to be able to float on the water surface. The working principle of the anti - evaporation floating ball is mainly to cover the water surface, reduce the direct contact between the water surface and the atmosphere, and thus reduce the evaporation rate. However, when the floating balls in the related art are laid in a reservoir, due to the gaps between the spheres that cannot be closely paved, part of the water surface is directly exposed to the air. Moreover, the spheres are prone to roll in the water, taking out the water in the reservoir and then evaporating, thereby reducing the anti - evaporation rate of the floating balls.

[0030] In order to solve the problems that the anti - evaporation floating device cannot be closely paved and is prone to roll in the water, the embodiments of the present application provide a floating device for preventing evaporation on the water surface.

[0031] Refer to Figures 1 to 8 , the embodiments of the present application disclose a floating device for preventing evaporation on the water surface. The floating device includes a plurality of floating balls 1. The spherical surface of the floating ball 1 is provided with a plurality of circular planes 11. The centers of the plurality of circular planes 11 are in the same plane, and the plurality of floating balls 1 are mutually attached through the circular planes 11.

[0032] Specifically, the floating device can be composed of a plurality of floating balls 1, which can float on the water surface, and a plurality of planes can be set around each floating ball 1, that is, a plurality of pieces are cut off around the floating ball 1, and the remaining parts form a plurality of circular planes 11 around the floating ball 1. The centers of the plurality of circular planes 11 around the spherical surface of the floating ball 1 are located on the same latitude of the floating ball 1, that is, the centers of the plurality of circular planes 11 are in the same plane, and the centers of these circular planes 11 are in the same horizontal plane.

[0033] Multiple floating balls 1 fit together through these circular planes 11 to form a continuous covering layer. When the floating balls 1 float in the water, the floating balls 1 can fit together through the circular planes 11. Since the contact surface between the floating balls 1 is a plane, the problem of gaps between the spheres in the traditional spherical contact method is avoided, the direct contact area between the water surface and the atmosphere is effectively reduced, and the anti-evaporation effect is improved. At the same time, since the contact surface between the floating balls 1 is a plane, it is not easy to produce a rolling effect between the spheres, which enhances the stability and integrity of the floating balls 1 on the water surface, making the equipment more durable and efficient. In addition, this tightly fitting design also helps to reduce the impact of wind and waves on the floating balls 1, further improving the stability and service life of the equipment. In addition, since most of the surface area of the floating ball 1 is in a non-immersed state, only the edge part is in contact with water, and the floating ball 1 is not easy to roll, the probability of the water being brought to the side away from the water surface when the water-soaked side of the ball rolls is reduced, the water-soaking rate of the floating body is reduced, and the anti-evaporation effect of the floating device is further improved.

[0034] In the embodiment of the present application, the floating device for preventing evaporation on the water surface includes a plurality of floating balls 1, the spherical surface of the floating balls 1 is provided with a plurality of circular planes 11, the centers of the plurality of circular planes 11 are in the same plane, and the plurality of floating balls 1 are mutually fitted through the circular planes 11. The close paving of the devices in the water is achieved through the fitting of the circular planes, and the water surface can be completely covered, which solves the problem of contact gaps existing in conventional spherical solutions, improves the water surface coverage rate of the floating body, and further improves the anti-evaporation effect; the floating balls fit each other, have the stability of floating in the water, are not easy to roll over, and reduce the water-wetting rate of the floating balls, and the floating balls have a simple structure, are easy to prepare, and have a low cost.

[0035] Reference Figures 1 - 3 The multiple circular planes 11 in the same floating ball 1 are tangent to each other.

[0036] Specifically, in the same floating ball 1, the circular planes 11 can be arranged to be tangent to each other. The circular planes 11 can be arranged along the circumference of the floating ball 1. When the circular planes 11 are tangent to each other, the floating balls 1 can all be in contact with each other through the circular planes 11. When designing the floating ball, the circular planes on the surface of each sphere are closely adjacent and in contact with each other.

[0037] The circular planes 11 are tangent to each other in pairs, ensuring that the floating balls form a tight and continuous covering layer on the water surface. This tight fit can effectively reduce the direct contact area between the water surface and the atmosphere, thereby reducing water surface evaporation. The floating balls 1 can contact each other through these circular planes to form a stable structure. This contact helps to improve the stability of the floating balls in the water and is not easily affected by external forces such as wind and waves. The tangent design of the circular planes 11 facilitates standardized production, which can improve production efficiency and reduce costs. In addition, standardized production also helps to ensure the consistency of the quality and performance of each floating ball.

[0038] Refer to Figure 4 , the connection line between the tangent points of adjacent circular planes 11 in the same floating ball 1 is a regular polygon 12.

[0039] Specifically, since the floating balls 1 are tangent to each other in pairs, connecting the tangent points of the circular planes in sequence can form a regular polygon 12. Multiple floating balls can be densely paved on the water surface.

[0040] Refer to Figure 3 , the plane where the regular polygon 12 is located passes through the center of the sphere of the floating ball 1.

[0041] Specifically, the plane where the regular polygon 12 is located passes through the center of the sphere of the floating ball 1, that is, the plane where the regular polygon 12 is located is the position with the largest circumference of the spherical surface of the floating ball 1, similar to the equator position of the earth. At this time, on both sides of the regular polygon 12, the floating balls are symmetrical.

[0042] Refer to Figures 4 - 5 , the regular polygon 12 is a regular hexagon.

[0043] Specifically, the regular polygon 12 can be set as a regular hexagon. Since the interior angle of a regular hexagon is 120°, when the floating balls 1 float in the water, every three floating balls 1 can just be in complete contact, achieving a dense paving effect.

[0044] Taking a conventional floating ball device with a diameter of 10 cm and the floating device in the embodiment of the present application with corresponding dimensions as an example, refer to Figure 5 , for the core combination shape of 7 floating balls, the covering area of the conventional circular ball is about 0.054978 m 2 , the covering area of the floating device in the embodiment of the present application is about 0.060622 m 2 , and the increase in the covering area reaches 10.3%. The floating device improves the water surface coverage rate of the floating body and enhances its anti-evaporation effect for the reservoir.

[0045] It should be noted that the regular polygon can also be set as a regular quadrilateral. When the floating ball 1 floats in water, every four floating balls 1 can just come into complete contact, achieving a close-packing effect.

[0046] Referring to Figures 2 - 3 , the floating ball 1 is an ellipsoid.

[0047] Specifically, the floating ball 1 is an ellipsoid. The floating ball 1 takes the plane where the regular polygon 12 is located as the symmetry plane, and both the upper and lower sides can be semi-ellipsoids. When the floating ball 1 floats on the water surface and the water surface is stationary, the plane where the regular polygon 12 is located is parallel to the water surface, and a part of the ellipsoidal surface on one side is immersed in the water, and the other side is away from the water surface.

[0048] Referring to Figure 3 , an external force acts on the curved surface of the upper half of the floating body exposed to the air, causing the floating body to generate a moment of inertia and thus roll over. Taking the vertical longitudinal section as an example, referring to Figure 6 , the axis of rotation is the axis of symmetry of the floating body passing through the center of gravity and perpendicular to the longitudinal section. The moment of inertia that causes the floating ball 1 in the embodiment of the present application to rotate along the axis of rotation is L = m(a 2 + b 2 ) / 4, where m is the mass of the floating body, a is the major semi-axis of the ellipse in the longitudinal section, and b is the minor semi-axis of the ellipse in the longitudinal section. The calculation of the moment of inertia of the remaining longitudinal sections is the same, and its value is between m(a 2 + b 2 ) / 4 and mb 2 / 2.

[0049] For the conventional spherical floating body 2, taking the vertical longitudinal section as an example, referring to Figure 7 , the axis of rotation is the axis of symmetry of the floating body passing through the center of gravity and perpendicular to the longitudinal section. The moment of inertia that causes the conventional spherical floating body 2 to rotate along the axis of rotation is L' = m'b' 2 / 2, where m' is the mass of the floating body and b' is the radius of the circle in the longitudinal section.

[0050] Under the condition of the same mass, by design, the floating ball 1 in the embodiment of the present application has a larger moment of inertia. Compared with the conventional spherical floating body 2, its stability in water can be improved. The moment of inertia is a measure of the inertia of an object rotating about an axis, similar to mass in linear motion but playing a similar role in rotational motion. The magnitude of the moment of inertia depends on the mass, shape of the object, and the position of the mass distribution relative to the axis of rotation. A larger moment of inertia means that the object is more difficult to change its rotational state when subjected to an external force, so it is less likely to roll over. The larger the moment of inertia, the stronger the resistance of the object to changing its rotational state. This means that when subjected to an external force, an object with a larger moment of inertia is less likely to change its rotational state, such as rolling over.

[0051] In the embodiments of the present application, a heavy object can be arranged inside the floating ball 1 or a material with a uniform density distribution can be used, so that the mass distribution is more concentrated or uniform, thereby increasing its moment of inertia. The shape of the floating ball 1 is different from that of a conventional spherical floating body, and an elliptical design is adopted, which can increase the moment of inertia of rotation around a specific axis. When the floating ball 1 floats in water, it can better resist the influence of external forces such as wind and waves, maintain a stable floating state, and is not easy to roll over. This not only improves the stability of the floating ball 1, but also reduces its water contact rate, thereby more effectively reducing the evaporation loss of the water surface.

[0052] In the embodiments of the present application, the floating ball 1 is set as an ellipsoid, increasing the moment of inertia, and achieving higher stability and lower water contact rate.

[0053] It should be noted that in the embodiments of the present application, the floating ball 1 can also be a regular sphere.

[0054] Refer to Figure 2 、 5 、6, the length of the major axis of the ellipsoid is equal to the length of the diagonal of the regular hexagon, and the lengths of the minor axes in two directions of the ellipsoid are equal to the length of the line connecting the midpoints of the opposite sides of the regular hexagon.

[0055] Specifically, the length of the major axis of the ellipsoid is equal to the length of the diagonal of the regular hexagon. The distances from the vertices of the regular hexagon to the center of the ellipsoid are equal, and the vertices of the regular hexagon can form a regular circle with the center of the ellipsoid as the center. The major axis of the ellipsoid is equal to the diameter of the regular circle. The minor axis of the ellipsoid is equal to the length of the line connecting the midpoints of the opposite sides of the regular hexagon.

[0056] In order to more clearly express the geometric shape of the ellipsoidal floating ball, the construction process of the geometric shape of the ellipsoid will be introduced below.

[0057] 1. Draw the top-view cross-section of the regular hexagon of the floating ball

[0058] According to the required target size, draw a regular hexagon as the top-view cross-section of the floating ball 1.

[0059] 2. Draw the ellipsoid

[0060] On the top-view plane, draw a regular circle with the length of any diagonal connection of the regular hexagon as the diameter and the center point of the regular hexagon as the center. This regular circle is the top-view cross-section of the target ellipsoid;

[0061] Taking the length of the diagonal connection of the above regular hexagon as the major axis and the length of the perpendicular connection of any pair of opposite sides of the regular hexagon as the minor axis, draw an ellipse. This ellipse is the front-view cross-section of the target ellipsoid.

[0062] Based on the regular circle of the top-view cross-section and the ellipse of the front-view cross-section, the target ellipsoid can be established.

[0063] 3. Stretch to obtain a hexagonal prism 3

[0064] Taking the regular hexagon as the face, stretch the height of the minor axis of the ellipse vertically upward and downward along the center respectively, and a hexagonal prism 3 can be obtained. The hexagonal prism 3 and the ellipse should have equal height in the vertical direction.

[0065] 4. Obtain the geometric shape of the ellipsoidal floating device through Boolean operation.

[0066] Place the obtained ellipsoid in alignment with the center of the hexagonal prism 3 in three-dimensional space to obtain the Figure 8 geometric combination form as described.

[0067] Perform the Boolean operation of "intersection" on the hexagonal prism 3 and the ellipsoid, that is, the geometric shape of the ellipsoidal floating device is obtained, which is the common volume part where the hexagonal prism 3 and the ellipsoid intersect. Boolean Operations is a logical operation based on Boolean algebra, mainly used to process binary data and logical expressions. The basic operations of Boolean operations include AND, OR, NOT, and other operations composed of these basic operations, such as XOR, XNOR, etc. These operations have wide applications in the fields of computer science, electronic engineering, mathematical logic, etc. Through Boolean operation, the geometric shape of the ellipsoidal floating device is obtained.

[0068] In summary, the construction of the improved geometric shape of the ellipsoidal floating device provided by this solution is completed.

[0069] It should be noted that the length of the minor axis can also be designed according to actual needs, that is, the length of the minor axis can be larger or smaller. When the length of the minor axis is smaller, the ellipsoid can be flatter, and when the length of the minor axis is larger, the ellipsoid will be rounder.

[0070] Refer to Figure 2 , the sizes of the multiple circular planes in the same floating ball 1 are the same.

[0071] Specifically, in the same floating ball 1, there can be multiple circular planes, and the size of each circular plane can be the same. The multiple circular planes in the same floating ball having the same size means that when designing the floating ball, the circular planes on the surface of each sphere have the same diameter. The circular planes of the same size can be evenly distributed on the surface of the floating ball, ensuring that the floating ball can float stably on the water surface and is not prone to rolling. All the circular planes having the same size helps to maintain the structural stability of the floating ball. This consistency can reduce the stress concentration caused by planes of different sizes and improve the durability of the floating ball. The circular planes of the same size facilitate mass production and quality control. Manufacturers can use the same molds and processes to produce these planes, thereby improving production efficiency and reducing costs. All the circular planes having the same size ensures the consistency of the floating ball in terms of the anti-evaporation function. This consistency helps to improve the overall performance and efficiency of the entire floating device.

[0072] Refer to Figure 1 、 4 、5, the multiple floating balls are of the same size.

[0073] Specifically, the water surface anti-evaporation device can be composed of multiple floating balls 1, and the size of each floating ball 1 can be the same. When the floating balls 1 float on the water surface, due to the same size of the floating balls 1, close packing can be achieved. At the same time, floating balls of the same size are convenient for standardized production, which can improve production efficiency and reduce costs. In addition, standardized production also helps to ensure the consistency of the quality and performance of each floating ball. Moreover, floating balls of the same size have better stability in water because they have the same buoyancy and weight distribution, which helps to maintain the balance and stability of the entire covering layer. The floating balls 1 of the same size can be evenly distributed on the water surface to form a continuous and uniform covering layer, effectively reducing the direct contact area between the water surface and the atmosphere, thereby reducing evaporation.

[0074] Refer to Figures 1 - 8 , the floating ball 1 is of a hollow structure.

[0075] Specifically, the floating ball 1 can be a hollow sphere. A hollow sphere is a spherical object with a hollow interior and an outer spherical shell.

[0076] The hollow sphere can be produced by injection molding, blow molding, rotational molding (rotational forming), 3D (Three-Dimensional) printing, etc.

[0077] The spherical structure does not have complex connected components, and the manufacturing process is simple, and maintenance and repair are also easier and more economical.

[0078] In the embodiments of the present application, the floating device includes a plurality of floating balls. A plurality of circular planes are arranged on the spherical surface of the floating balls. The centers of the plurality of circular planes are in the same plane. The plurality of floating balls are mutually attached through the circular planes, and the devices are closely paved with each other through the attachment of the circular planes in water, achieving complete coverage of the water surface, solving the contact gap problem existing in the conventional spherical solution, improving the water surface coverage rate of the floating body, and further improving the anti-evaporation effect. The floating balls are mutually attached to each other, having stability in floating in water, not easily rolling over, reducing the water wetting rate of the floating balls, and the floating ball structure is simple, easy to prepare, and has a low cost.

[0079] It should be noted that in this article, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.
