Description

Technical Field

[0001] This utility model relates to an anti-evaporation ball, and more particularly to a reservoir anti-evaporation ball with a compact assembly structure. Background Technology

[0002] The shading effect of shade balls is achieved by laying several hollow, floating spheres on the water's surface to form a shading layer, thus blocking direct sunlight and reducing evaporation. When this technology was first used, black shade balls were laid flat on the water surface, effectively reducing evaporation from reservoirs and saving significant amounts of water for agricultural irrigation. However, the shade balls constantly rotate due to wind and water surface fluctuations. This causes the upper parts of the balls, which absorb heat and become warmer, to rise to the surface. This heat transfer to the water surface further increases the water temperature and causes evaporation. Furthermore, the increased temperature leads to an increase in microorganisms in the water, resulting in deteriorated water quality.

[0003] To address this technical problem, existing technologies employ methods such as adding counterweights and installing connecting parts on the sides of the sphere to prevent it from tipping over. For example, Chinese Utility Model Patent 202210257151.X describes a sunshade ball that can provide shade and generate solar power. The patent proposes that the upper half of the sphere has a solar panel attached to its surface, a ring of suction strips is arranged around its middle section, and a counterweight is located inside the lower part of the sphere. This patent uses the suction strips to hold adjacent spheres together, preventing them from tipping over; the addition of a counterweight in the lower part of the sphere further enhances the ability to prevent tipping. Chinese utility model patent 201811286027.6 describes a sunshade ball that can effectively suppress water evaporation and has strong wind resistance. It also uses a magnetic plastic ring around the outer circumference of the sphere, and sets the number of adsorption surfaces that attract each other to a multiple of six. This allows the hollow spheres to attract each other and connect into a sheet, maximizing the area of ​​the hollow spheres that cover the water surface.

[0004] The drawback of these two methods of connecting sunshade balls using magnetism is that the magnetic attraction method is prone to misalignment. Once two sunshade balls are misaligned and magnetically attracted, it will cause a chain reaction that leads to more sunshade balls being misaligned, resulting in a larger area of ​​the sunshade balls being exposed above the water.

[0005] The following problems also exist: Firstly, typical sunshade balls are made of PVC with very thin walls. The aforementioned patent does not explain how to fix the suction strips to the ball. If the strips are embedded in the ball's surface, fixing grooves and slots need to be created on the surface. The common process for plastic spherical products is: polyethylene → extrusion preform → blow molding → finished product. Creating fixing grooves and slots on the outer wall undoubtedly increases the processing steps, and this poses a significant processing difficulty for balls with a wall thickness of less than 2mm. Increasing the wall thickness would increase production costs. Secondly, if the strips are bonded to the ball's surface, the adhesive is prone to cracking under prolonged exposure to sunlight, causing the strips to detach from the ball. With the ripples of water, the detached strips will bounce up and down, impacting the solar panel above, which is easily damaged. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a compact reservoir anti-evaporation ball with a one-piece molding process and a joint structure that is not prone to stacking or misalignment of the joint parts.

[0007] The purpose of this application is achieved as follows: a compactly assembled reservoir anti-evaporation sphere, comprising a sphere and a docking part integrally connected to the sphere and protruding outward, the sphere comprising a sunshade part on the upper side and a floating part on the lower side, the docking part being a hollow ring with open upper and lower ends, the upper surface of the hollow ring being composed of several continuous upward-protruding arc-shaped convex surfaces, the lower surface of the hollow ring being composed of several continuous downward-protruding arc-shaped convex surfaces, the sunshade part being a hollow body with an open lower end, the lower port of the sunshade part being integrally connected to the upper port of the docking part, and the floating part being a hollow body with an open upper end, the upper port of the floating part being integrally connected to the lower port of the docking part.

[0008] The sunshade part and the floating part have the same shape and are arranged symmetrically. The cavity is a hemisphere or a spherical cap.

[0009] The sunshade and the floating part are asymmetrically arranged, and both the sunshade and the floating part are spherical caps. The height of the hollow spherical cap of the sunshade is less than the height of the hollow spherical cap of the floating part.

[0010] An opening is provided at the bottom of the floating part, and a plug is sealed inside the opening. A counterweight is injected into the floating part through the opening, and the counterweight can be a liquid.

[0011] The docking part includes a vertical docking surface and an upper inclined surface connected to the upper side and a lower inclined surface connected to the lower side of the docking surface.

[0012] The upper edge of the upper slope forms the upper port of the docking part, and the lower port of the sunshade part is integrally connected to the upper edge of the upper slope; the lower edge of the lower slope forms the lower port of the docking part, and the upper port of the floating part is integrally connected to the lower edge of the lower slope.

[0013] The mating surface is composed of six continuous vertical planes connected end to end. The upper edge of each vertical plane is an upward convex arc, and the upper edge is integrally connected to an upward convex arc surface. The lower edge of each vertical plane is a downward convex arc, and the lower edge is integrally connected to a downward convex arc surface.

[0014] The arc-shaped convex surface is an arc-shaped surface that is high in the middle and low on both sides. The two sides of the six arc-shaped convex surfaces on the upper side are connected end to end to form an upper inclined surface, and the two sides of the six arc-shaped convex surfaces on the lower side are connected end to end to form a lower inclined surface.

[0015] The connection between the upper edges of the two vertical planes and the corresponding two curved convex surfaces form a downward-sloping, smooth arc angle, which constitutes the lowest point of the upper inclined surface.

[0016] The lower edges of the two vertical planes connect with the corresponding two curved convex surfaces to form a smooth, upward-sloping arc angle, which constitutes the highest point of the lower slope.

[0017] This application, based on existing technology, forms a sphere with a mating section in a single process of extruding a preform and then blow molding, reducing the number of steps and saving time and costs. Injecting liquid into the sphere allows it to retain its self-righting function, preventing heat from the upper part of the sphere from being carried into the water and reducing water evaporation. The injection hole can be heat-sealed with the same material. Therefore, this application demonstrates a simple structure, fewer manufacturing steps, and achieves an anti-tipping effect. The overall structure is integrally molded and suitable for practical production.

[0018] Compared to existing technologies, this application does not use magnetic attraction to connect several sunshade balls. Instead, it uses the curved surfaces of the upper and lower slopes to make the contact between the joints of the sunshade balls line contact when they overlap, resulting in minimal friction. Therefore, they can slide down naturally by their own weight, making it difficult for the joints to overlap. When sliding down, the joints of adjacent sunshade balls can be pressed down, generating an outward pushing force, which causes the adjacent sunshade balls to move outward, exposing the splicing gaps and achieving the purpose of orderly splicing.

[0027] This application is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this application and the actual situation.

[0028] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0029] The present invention will be further described below with reference to embodiments and accompanying drawings. Embodiment 1: As shown in the figure... Figure 1 , 2 As shown in Figures 3 and 4, a compactly assembled reservoir anti-evaporation ball includes a sphere and a docking part 3 integrally connected to the sphere and protruding outward. The sphere includes a sunshade part 1 on the upper side and a floating part 5 on the lower side. The docking part 3 is a hollow ring with open upper and lower ends. The upper surface of the hollow ring is composed of several continuous upward-protruding arc-shaped convex surfaces, and the lower surface of the hollow ring is composed of several continuous downward-protruding arc-shaped convex surfaces. The sunshade part 1 is a hollow body with an open lower end, and the lower port of the sunshade part 1 is integrally connected to the upper port of the docking part 3. The floating part 5 is a hollow body with an open upper end, and the upper port of the floating part 5 is integrally connected to the lower port of the docking part 3.

[0030] Furthermore, the sunshade part 1 and the floating part 5 have the same shape and are symmetrically arranged, and the cavity is a hemisphere or a spherical crown. The advantage of this arrangement is that even if the whole structure is rotated 180° in extreme cases, it will still be the same as the previous structure and will not affect the subsequent sunshade and splicing effects.

[0031] Example 2: As Figure 5 , 6As shown, a compact, modular reservoir anti-evaporation sphere includes a sphere and a connecting part 3 integrally connected to the sphere and protruding outward. The sphere includes a sunshade part 1 on the upper side and a floating part 5 on the lower side. The connecting part 3 is a hollow ring with open upper and lower ends. The upper surface of the hollow ring is composed of several continuous upward-protruding arc-shaped convex surfaces, and the lower surface of the hollow ring is composed of several continuous downward-protruding arc-shaped convex surfaces. The sunshade part 1 is a hollow body with an open lower end, and the lower port of the sunshade part 1 is integrally connected to the upper port of the connecting part 3. The floating part 5 is a hollow body with an open upper end, and the upper port of the floating part 5 is integrally connected to the lower port of the connecting part 3. The sunshade part 1 and the floating part 5 are asymmetrically arranged.

[0032] Furthermore, the sunshade part 1 and the floating part 5 are spherical, with the height of the hollow spherical crown of the sunshade part 1 being less than the height of the hollow spherical crown of the floating part 5. They are similar in shape but asymmetrically arranged. This structural arrangement shifts the overall center of gravity to the lower side of the docking part 3, preventing the whole from flipping over when blown by the wind on the water surface.

[0033] To further lower the overall center of gravity, an opening is made at the bottom of the floating part 5, and a plug 7 is sealed inside the opening. A counterweight, which can be water, is injected into the floating part 5 through the opening. The injection of water creates a self-sustaining effect, making the entire unit more difficult to flip, thus ensuring that the sunshade part 1 remains stably upward and the floating part 5 remains stably downward.

[0034] Furthermore, in embodiments 1 and 2, the docking part 3 includes a vertical docking surface and an upper inclined surface 2 and a lower inclined surface 4 respectively connected to the upper side and the lower side of the docking surface.

[0035] The upper edge of the upper inclined surface 2 forms the upper port of the docking part 3, and the lower port of the sunshade part 1 is integrally connected to the upper edge of the upper inclined surface 2.

[0036] The lower edge of the lower slope 4 forms the lower port of the docking part 3, and the upper port of the floating part 5 is integrally connected to the lower edge of the lower slope 2.

[0037] Furthermore, the mating surface is composed of six continuous vertical planes connected end to end. The upper edge of each vertical plane is an upwardly convex arc, and the upper edge is integrally connected to an upwardly convex arc-shaped convex surface. The lower edge of each vertical plane is a downwardly convex arc, and the lower edge is integrally connected to a downwardly convex arc-shaped convex surface.

[0038] The arc-shaped convex surface is an arc-shaped surface that is high in the middle and low on both sides. The two sides of the six arc-shaped convex surfaces on the upper side are connected as one to form an upper inclined surface 2, and the two sides of the six arc-shaped convex surfaces on the lower side are connected as one to form a lower inclined surface 4.

[0039] Furthermore, the connection between the upper edges of the two vertical planes and the corresponding two curved convex surfaces form a downward-sloping, smooth arc angle, which constitutes the lowest end of the upper inclined surface 2.

[0040] Furthermore, the lower edges of the two vertical planes connect with the corresponding two curved convex surfaces to form an upwardly sloping, rounded arc angle, which constitutes the highest point of the lower inclined surface 4.

[0041] This structure creates a smooth surface at the junction of the middle of each arc-shaped convex surface of the upper inclined surface 2 and the upper edge of each pair of vertical planes. This ensures that if the mating parts 3 overlap, the contact between the mating parts 3 will be line contact with minimal friction. Therefore, they can slide down naturally under their own weight, making it difficult for the mating parts 3 to overlap.

[0042] Based on existing technology, this application can form a sphere with a docking part 3 in one process of extruding a preform and blowing it. An opening is provided at the bottom of the floating part 5, and filling liquid is injected into the sphere through the injection hole. Then, the plug 7 is formed by heat sealing with the same material. This allows the whole to retain the function of a roly-poly toy after being thrown into the water, preventing the heat of the sunshade part 1 from being carried into the water and reducing the amount of water evaporation.

[0043] In use, this application is thrown onto the surface of a reservoir, completely covering the water. As the water ripples, the application floats to one side, and under the force of the thrust, the individual spheres naturally form a continuous spliced ​​structure through their connecting parts 3. During this process, if the application overlaps, due to its spherical shape, it will naturally move downwards under its own weight, and the connecting parts 3 on each sphere will slide down naturally along the upper and lower inclined surfaces 2 and 4, thus ensuring the orderly connection of the spheres. Each sphere only rises and falls with the water's surface, so even if the upper part of the sphere is heated, the hollow structure makes it difficult for heat to conduct downwards, thereby achieving the purpose of shielding heat from conduction to the water surface, thus reducing water temperature and evaporation.

[0044] The above description is merely an example for clearly illustrating this application and is not intended to limit the implementation of this application. Any obvious variations or modifications derived from the technical solutions of this application are still within the protection scope of this application.
