Description

Technical Field

[0001] The invention relates to the technical field of water resource protection and water saving, in particular to an evaporation-resistant float which can prevent irregular floating and automatically reset. Background Art

[0002] To reduce ineffective evaporation from reservoirs in arid regions, existing technologies include: polystyrene sheet coverings; a method for preventing reservoir evaporation using floating solar panels; a system for preventing evaporation from reservoirs using graphite flakes laid on the surface of the reservoir to form a discontinuous graphite film; a system for preventing evaporation using graphite powder; floating devices that inhibit algae growth and reduce evaporation; a system for covering the water surface with a large number of round buoyant balls placed in the reservoir; and a water storage evaporation control (a floating modular cover for water storage). While all of these methods can prevent evaporation from the reservoir surface, they all suffer from issues such as being easily blown away by wind and being difficult to use on windy water surfaces such as lakes.

[0003] In recent years, steam-blocking float technology has been developed, such as:

[0004] (1) The Chinese invention patent application number 202311611253.8 provides a vapor barrier float and its use method, which is composed of a polygonal plate structure that can be continuously and seamlessly spliced ​​and a vertical structure arranged under the plate structure, and the polygonal plate structure is capable of floating on the water surface; the vertical structure is a hollow cone-shaped vertical structure with an upper end connected to the bottom side of the polygonal plate structure, and a one-way valve mechanism capable of filling the hollow cone is provided at the bottom of the hollow cone-shaped vertical structure, and a water inlet provided at the bottom is connected to the water inlet channel of the one-way valve mechanism; a one-way exhaust valve capable of exhausting air to the outside is provided on the side wall of the hollow cone-shaped vertical structure. By connecting the vapor barrier floats in series through the connecting mechanism, a covering body covering the water surface of the reservoir can be formed.

[0005] (2) Chinese invention patent application number 202410833129.4 provides a vapor barrier float comprising a vertical body and a floating ring mechanism arranged around the vertical body and forming an integral structure with the vertical body; the radial outer side of the floating ring mechanism is a polygonal structure that can be spliced. By connecting the vapor barrier floats together through a connecting mechanism, a covering body can be formed to cover the water surface of the reservoir.

[0006] The non-fixed liquid counterweight in the anti-evaporation float provided above causes the center of gravity to shift or even reverse due to the flow of external force, forming a new center of gravity. The force on the float is redistributed, resulting in inversion, uprightness, semi-lying floating or even overlapping problems, which affects the anti-evaporation effect of the covering body covering the water surface of the reservoir.

[0007] Therefore, it is necessary to develop a kind of anti-evaporation float which prevents irregular floating and can automatically reset to solve the above problems. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide an anti-evaporation float that prevents irregular floating and can automatically reset. The center of gravity of the anti-evaporation float can be fixed, so that it can return to its original position no matter which direction the force is applied to it during the impact of wind and waves. This effectively solves the problem that the center of gravity of the non-fixed liquid counterweight in the conventional float is shifted or even reversed due to the flow of external force, forming a new center of gravity, and the force of the float is redistributed, which leads to reversal, uprightness, semi-lying floating or even stacking.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0010] A vaporization-resistant float that prevents irregular floating and can automatically reset comprises a hollow, saucer-shaped float body, a counterweight fixedly arranged at the center of the float body, and a port sealing cover for fixing the counterweight. The outer periphery of the float body is a regular hexagonal structure; the float body is symmetrical in top and bottom. When 90-95% of the volume of vaporization-resistant liquid is injected into the counterweight body, the specific gravity remains unchanged.

[0011] A further improvement of the technical solution of the present invention is that: the float body is integrally formed, including a floating ring with a regular hexagonal outer periphery floating on the water surface, an arc-shaped upper cover body arranged above the floating ring, and an arc-shaped lower cover body arranged below the floating ring; the upper cover body and the lower cover body are symmetrically arranged, and the curvature, thickness and material of the upper cover body and the lower cover body are consistent.

[0012] A further improvement of the technical solution of the present invention is that the arc elevation angles of the upper cover body and the lower cover body are not less than 10°.

[0013] A further improvement of the technical solution of the present invention is that: the top end of the upper cover body is provided with a plurality of protruding slots for fixing the counterweight body; the bottom end of the lower cover body is provided with a cylindrical groove for clamping the counterweight body.

[0014] A further improvement of the technical solution of the present invention is that the protruding height of the card slot is 2 mm.

[0015] A further improvement of the technical solution of the present invention is that a port fixing thread matching the port sealing cover is provided in the groove.

[0016] A further improvement of the technical solution of the present invention is that: the counterweight body is an integrally formed cylindrical barrel structure, and a liquid injection port and a sealing cover are provided at the bottom end of the counterweight body; a plurality of empty grooves for preventing pre-deformation in winter frost heave are provided on the side wall of the counterweight body; when the top end of the counterweight body contacts and matches the top end of the float body, a plurality of fixing ribs are provided at the top end of the counterweight body.

[0017] A further improvement of the technical solution of the present invention is that the thickness of the fixing rib is 2 mm.

[0018] A further improvement of the technical solution of the present invention is that the top end of the counterweight body can be fixedly installed at any height in the center of the float body.

[0019] A further improvement of the technical solution of the present invention is that the weight of the counterweight body after 90-95% of the volume of the vapor-restricted liquid is injected is equal to the displacement of the float body when it floats on the vapor-restricted liquid.

[0020] Due to the adoption of the above technical solution, the technical advancements achieved by the present invention are:

[0021] 1. The present invention configures the float body as a blow-molded (or injection-molded) integral structure with a hollow saucer-shaped outer periphery and a regular hexagonal shape. The upper and lower covers are symmetrically arranged, and have the same curvature and material. This ensures that the wall thickness of the upper and lower covers is uniform during injection molding, and the upper and lower covers have consistent strength and service life. The simple structure ensures the service life of the evaporation-resistant float. The regular hexagonal structure ensures that the individual units of the evaporation-resistant float can be freely assembled and fitted together, which is conducive to forming a covering body on the water surface that covers the reservoir water surface. The thickness and material are consistent at all points in the float body, ensuring a consistent service life of the evaporation-resistant float during operation.

[0022] 2. The present invention sets the counterweight body as a cylindrical barrel structure formed in one step, and injects 90-95% of the volume of the evaporation-resistant liquid counterweight, so that the counterweight body forms a solid core integral structure and is fixed in the center of the hollow float body. That is, the center of gravity of the evaporation-resistant float is fixed in the center of the interior, and the center of gravity remains unchanged. When wind and waves come, the evaporation-resistant float will drift up and down with the wind and waves, but the downward gravity of the fixed force direction and orientation of the fixed center of gravity can keep the evaporation-resistant float in its original shape and will not float irregularly. Even after floating, it can automatically reset, so that the evaporation-resistant float can float flat on the water surface in sheets to form a covering body, thereby achieving the purpose of preventing water evaporation.

[0023] 3. In the present invention, the arc elevation angles of the upper cover and the lower cover are set to be no less than 10°, so that the evaporation-resistant floats can slide down quickly when encountering wind and waves, thereby ensuring that the evaporation-resistant floats can float on the water surface in pieces to form a complete covering body.

[0024] 4. The protruding height of the card slot in the present invention is 2 mm, which ensures the uniform thickness of the upper cover body, makes it easier to achieve one-piece injection molding, and can better fix the counterweight body.

[0025] 5. In the present invention, a groove for fixing the counterweight body is provided at the bottom end of the lower cover body, and a port fixing thread matching the port sealing cover is provided in the groove, thereby ensuring the sealing performance after the counterweight body is installed in the float body and facilitating the disassembly and assembly of the anti-evaporation float during maintenance.

[0026] 6. The present invention provides a liquid injection port and a sealing cover at the bottom end of the counterweight body, which facilitates the injection and sealing of the anti-evaporation liquid in the counterweight body, and ensures that the weight of the counterweight body will not change at any time during the use of the anti-evaporation float; an empty groove is provided on the side wall of the counterweight body to prevent frost heave pre-deformation in winter, which ensures that the counterweight body will not be pre-deformed by frost heave caused by the drop in weather temperature in winter, and effectively ensures that the center of gravity of the anti-evaporation float remains unchanged in winter.

[0027] 7. In the present invention, a plurality of fixing ribs with a thickness of 2 mm are provided on the top of the counterweight body to ensure that when the counterweight body is inserted into the float body, the fixing ribs can coincide with the slots on the upper cover body, further ensuring the fixed position of the counterweight body and effectively ensuring the stability of the center of gravity.

[0028] 8. The top end of the counterweight 1 in the present invention can be fixedly installed at any height in the center of the float body, so that the counterweight is not restricted by the space of the float body.

[0029] 9. In the present invention, the weight of the counterweight after 90-95% of its volume is injected with the hindered evaporation liquid is equal to the displacement of the float body when floating on the hindered evaporation liquid. According to Archimedes' principle, after the evaporation-resistant float is thrown into the water, the weight of the water displaced equals the buoyancy of the float weight (Gwater displacement = Gfloat). The fixed counterweight set inside the evaporation-resistant float with no center of gravity shift and no weight change can keep the center of gravity of the float fixed, so that it can return to its original position regardless of the direction of force it is subjected to during wind and wave impact. This effectively solves the problem of non-fixed liquid counterweights in conventional floats causing the center of gravity to shift or even reverse due to the flow of external forces, forming a new center of gravity, redistributing the force on the float, and then causing inversion, uprightness, semi-lying floating, or even stacking.

[0035] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or apparatuses.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "several" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0039] like Figure 1 、 Figure 2 、 Figure 3 As shown, an anti-evaporation float that prevents irregular floating and can automatically reset includes a hollow flying saucer-shaped float body, a counterweight body 1 fixedly arranged at the center of the float body, and a port sealing cover 3 for fixing the counterweight body 1. The outer periphery of the float body is a regular hexagonal structure; the float body has a vertically symmetrical structure; 90-95% of the volume of the anti-evaporation liquid is injected into the counterweight body 1, and the specific gravity does not change.

[0040] Specifically, the float body is configured as an integral blow-molded (or injection-molded) structure having a hollow flying saucer shape and a regular hexagonal outer periphery. The structure is symmetrically arranged from top to bottom and is made of HDPE (or PET). This ensures that the wall thickness of the upper cover 2 and the lower cover 5 are uniform during injection (or blow-molding) of the float body, and the upper cover 2 and the lower cover 5 have consistent strength and service life. The structure is simple, thereby ensuring the service life of the anti-evaporation float. The regular hexagonal structural setting ensures that the individual anti-evaporation float units placed on the water surface can be freely assembled and fitted together (without the need for a connecting device) without any gaps, which is conducive to forming a sheet of anti-evaporation water protection layer on the water surface (i.e., a covering body covering the water surface of the reservoir). The thickness of the float body is consistent with the material, thereby ensuring that the service life of the anti-evaporation float is consistent during operation.

[0041] The counterweight 1 is a one-piece cylindrical structure (similar to a mineral water bottle) made of HDPE (or PET). 90-95% of its volume is filled with a vapor-retarding liquid counterweight, forming a solid, integral structure. The counterweight 1 is fixed to the center of the hollow float body, thereby securing the center of gravity of the vapor-retarding float at the center. When wind and waves arrive, the vapor-retarding float will drift up and down with the waves. The presence of the counterweight 1 ensures that the vapor-retarding float is always subject to the downward force of gravity from the fixed center of gravity, imparting excellent stability and wind resistance to the float. This allows the float to maintain its original shape and prevent irregular floating. Even when strong winds cause the float to collapse or tilt, it remains restrained by the fixed center of gravity and automatically adjusts its floating posture to its normal, shielding position, allowing the float to float flat on the water surface, forming a blanket covering the reservoir surface and preventing water evaporation. The hindered evaporation liquid (water in this invention, or purified water) contained in the counterweight body is in a sealed state and an oxygen-free state, so it will not stink or turn green, just like the water in a mineral water bottle will not change color no matter how long it is left.

[0042] The arrangement of the float body and the counterweight body enables the anti-evaporation float to maintain an effective masking surface for a long time, which can be said to achieve maintenance-free use and effectively reduce the subsequent maintenance costs.

[0043] Further, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the float body is integrally formed, comprising a regular hexagonal float ring 4 that floats on the water surface, a curved upper cover 2 positioned above the float ring 4, and a curved lower cover 5 positioned below the float ring 4. The upper and lower covers 2 and 5 are symmetrically arranged, with the same curvature, thickness, and material. The float ring 4 has a certain height (generally greater than 5 cm) and has an upper edge and a lower edge. The lower edge represents the water level when the evaporation barrier float is floating on the water surface. It should be noted that when the evaporation barrier float is used upside down, the upper and lower edges are reversed.

[0044] Furthermore, the arc elevation angles of the upper cover body 2 and the lower cover body 5 are not less than 10°, so that the evaporation-resistant floats can slide down quickly when encountering wind and waves, thereby ensuring that the evaporation-resistant floats can float on the water surface in sheets to form a covering body covering the reservoir water surface.

[0045] Furthermore, the top of the upper cover 2 is provided with a plurality of protruding slots 2-1 for fixing the counterweight 1; the bottom of the lower cover 5 is provided with a cylindrical groove 5-1 for clamping the counterweight 1.

[0046] Furthermore, the protruding height of the slot 2-1 is 2 mm. When the float body is blow-molded (or injection-molded), due to the influence of the existing blow-molding process, the protruding height of the slot 2-1 can only be consistent with the thickness of the float body (thickness is 2 mm).

[0047] Furthermore, a port fixing thread 5-2 matching the port sealing cover 3 is provided in the groove 5-1, so that the port sealing cover 3 can be completely screwed into the groove 5-1. The port sealing cover 3 can cover the bottom of the counterweight body 1, ensuring the sealing performance of the float body structure and preventing water from entering the float body.

[0048] Furthermore, the counterweight body 1 is an integrally formed cylindrical barrel structure, and a liquid filling port 1-2 and a sealing cover are provided at the bottom end of the counterweight body 1; a plurality of empty grooves 1-3 are provided on the side wall of the counterweight body 1 to prevent pre-deformation due to frost heave in winter; when the top end of the counterweight body 1 touches and matches the top end of the float body, a plurality of fixing ribs 1-1 are provided at the top end of the counterweight body 1.

[0049] Furthermore, the thickness of the fixed rib 1-1 is 2 mm, which ensures that when the counterweight body is inserted into the float body, the fixed rib can match the slot on the upper cover body, further ensuring the fixed position of the counterweight body and effectively ensuring the stability of the center of gravity of the anti-evaporation float.

[0050] Furthermore, the top end of the counterweight 1 can be fixedly installed at any height in the center of the float body, so that the counterweight 1 is not restricted by the internal space of the float body.

[0051] Furthermore, the weight of the counterweight body 1 after 90-95% of the volume of the hindered vaporization liquid is injected is equal to the displacement of the float body when it floats on the hindered vaporization liquid.

[0052] Specifically, the weight of the counterweight body after 90-95% of the volume of the vapor-restricted liquid is injected is equal to the displacement of the float body when floating on the vapor-restricted liquid, that is, the weight of the float body, the counterweight body 1 and the port sealing cover 3 is equal to the displacement of the arc-shaped part of the lower cover body 5. When the vapor-restricted float floats on the water surface, the water level line cannot exceed the lower edge line of the floating ring 4 (at any time).

[0053] According to Archimedes' principle, after the evaporation-resistant float is thrown into the water, the weight of the discharged water = the buoyancy of the float (Gwaterdisplaced = Gfloat). The fixed counterweight with no center of gravity offset and no weight change set inside the evaporation-resistant float can keep the center of gravity of the evaporation-resistant float fixed, so that it can return to its original position no matter which direction the force is applied to it during the impact of wind and waves. This effectively solves the problem of non-fixed liquid counterweight in conventional floats causing the center of gravity to shift or even reverse due to the flow of external force, forming a new center of gravity, and the force redistributed on the float, which in turn causes the float to reverse, stand upright, float half-lying, or even overlap.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
