Description

Technical Field

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

[0002] In order to reduce the ineffective evaporation of water in reservoirs in arid areas, the prior art includes: a polystyrene board covering structure for reducing ineffective evaporation; a method for preventing reservoir evaporation by laying floating solar panels; using flake graphite powder to lay on the liquid surface of the reservoir to form a discontinuous graphite powder film; a system for preventing reservoir water evaporation using graphite powder; a floating device on the water surface for inhibiting algae growth and reducing water evaporation; pouring a large number of round floating balls into the reservoir to cover the water surface; Water Storage Evaporation Control (a floating module cover for a water storage device), etc. Although these methods above can achieve the purpose of preventing the evaporation of water on the reservoir surface, they all have problems such as being easily blown over by the wind and being difficult to meet the usage conditions for relatively windy water surfaces and lakes.

[0003] In recent years, the evaporation-resistant float technology has been developed, such as: (1) The Chinese invention patent with the application number 202311611253.8 provides an evaporation-resistant float and its using method, which is composed of a polygonal plate structure that can be continuously and seamlessly spliced and a pituitary structure arranged under the plate structure, and the polygonal plate structure can float on the water surface; the pituitary structure is a hollow conical pituitary structure with its upper end connected to the bottom side of the polygonal plate structure, and a one-way valve mechanism for filling water into its hollow cone is arranged at the bottom of the hollow conical pituitary structure, and the through inlet arranged at its bottom is communicated with the water inlet channel of the one-way valve mechanism; a one-way exhaust valve for exhausting air to the outside is arranged on the side wall of the hollow conical pituitary structure. By connecting these evaporation-resistant floats together through a connecting mechanism, a covering body covering the reservoir water surface can be formed.

[0004] (2) The Chinese invention patent with the application number 202410833129.4 provides an evaporation-resistant float, including a pituitary mechanism and a floating ring mechanism arranged on its periphery and integrated with it; the radially outer side of the floating ring mechanism is a polygonal structure that can be spliced. By connecting these evaporation-resistant floats together through a connecting mechanism, a covering body covering the reservoir water surface can be formed.

[0005] The non-fixed liquid counterweight in the evaporation-blocking float provided above generates flow under the action of external forces, causing the center of gravity to shift or even invert, forming a new center of gravity. The forces on the float are redistributed, resulting in problems such as inversion, erection, semi-lying float, or even stacking, which affects the evaporation-blocking effect of the covering formed to cover the reservoir water surface.

[0006] Therefore, it is necessary to develop an evaporation-blocking float that can prevent irregular floating and can automatically reset to solve the above problems. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an evaporation-blocking float that can prevent irregular floating and can automatically reset, which can keep the center of gravity of the evaporation-blocking float fixed, so that it can return to its original position regardless of the force from any direction during the impact of wind and waves, effectively solving the problem that the non-fixed liquid counterweight in the conventional float generates flow under the action of external forces, causing the center of gravity to shift or even invert, forming a new center of gravity, and the forces on the float are redistributed, resulting in problems such as inversion, erection, semi-lying float, or even stacking.

[0008] To solve the above technical problems, the technical solution adopted by the present invention is: An evaporation-blocking float that can prevent irregular floating and can automatically reset, including a hollow flying-saucer-shaped float body, a counterweight body fixedly arranged at the central position inside the float body, and a port sealing cover for fixing the counterweight body; the outer periphery of the float body is a regular hexagon structure; the float body is a vertically symmetric structure; 90-95% of the volume of the evaporation-blocking liquid is injected into the counterweight body, and the specific gravity remains unchanged.

[0009] 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 hexagon structure on the outer periphery floating on the water surface, an arc-shaped upper cover body arranged on the floating ring, and an arc-shaped lower cover body arranged under the floating ring; the upper cover body and the lower cover body are symmetrically arranged, and the radian, thickness, and material of the upper cover body and the lower cover body are the same.

[0010] A further improvement of the technical solution of the present invention is that: the elevation angles of the radian of the upper cover body and the lower cover body are not less than 10°.

[0011] A further improvement of the technical solution of the present invention is that: several protruding card slots for fixing the counterweight body are arranged at the top end of the upper cover body; a cylindrical groove for clamping the counterweight body is arranged at the bottom end of the lower cover body.

[0012] A further improvement of the technical solution of the present invention is that: the protruding height of the card slot is 2 mm.

[0013] A further improvement of the technical solution of the present invention is that: port fixing threads matching the port sealing cover are arranged in the groove.

[0014] A further improvement of the technical solution of the present invention lies in that: the counterweight is an integrally formed cylindrical barrel structure, and a liquid injection port and a sealing cover body are provided at the bottom end of the counterweight; a number of empty grooves for preventing pre-deformation due to winter frost heaving are provided on the side wall of the counterweight; when the top end of the counterweight touches and fits with the top end of the float body, a number of fixing ribs are provided at the top end of the counterweight.

[0015] A further improvement of the technical solution of the present invention lies in that: the thickness of the fixing rib is 2 mm.

[0016] A further improvement of the technical solution of the present invention lies in that: the top end of the counterweight can be fixedly installed at any height in the center of the float body.

[0017] A further improvement of the technical solution of the present invention lies in that: the weight of the counterweight after injecting 90 - 95% of the volume of the blocked evaporation liquid is equal to the displacement of the float body floating on the blocked evaporation liquid.

[0018] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is as follows: 1. The present invention sets the float body as an integrally blow-molded (or injection-molded) overall structure with a hollow flying saucer shape and a regular hexagon on the outer periphery. The upper cover body and the lower cover body are symmetrically arranged, and the radian and material are the same, so that the wall thickness of the upper cover body and the lower cover body can be ensured to be uniform during the injection molding of the float body, the strength of the upper cover body and the lower cover body is the same, the service life is the same, and the structure is simple, ensuring the service life of the evaporation-blocking float; the regular hexagon structure setting ensures that each individual unit of the evaporation-blocking float can be freely assembled and fitted with each other, which is beneficial to forming a covering body covering the reservoir water surface on the water surface; the thickness and material of each part of the float body are the same, ensuring the same service life during the operation of the evaporation-blocking float.

[0019] 2. The present invention sets the counterweight as a cylinder-shaped barrel structure formed in one time and injects 90 - 95% of the volume of the blocked evaporation liquid for counterweight, so that the counterweight forms a solid core overall structure and is fixed in the center of the hollow float body, that is, the center of gravity of the evaporation-blocking float is fixed in the center. The center of gravity remains unchanged. When the wind and waves come, the evaporation-blocking float will float up and down with the wind and waves, but the downward gravity force in the fixed direction and orientation of the fixed center of gravity can always keep the evaporation-blocking float in its original shape and will not float irregularly. Even after floating, it can automatically reset, enabling the evaporation-blocking float to float flat in sheets on the water surface to form a covering body, achieving the purpose of preventing water evaporation.

[0020] 3. In the present invention, the arc elevation angles of the upper cover and the lower cover are set to be 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 pieces to form a complete covering body.

[0021] 4. The protruding height of the card slot in the present invention is 2 mm, which ensures that the thickness of the upper cover body is consistent, making it easier to achieve one-piece injection molding and better fix the counterweight body.

[0022] 5. In the present invention, a groove capable of clamping and fixing the counterweight 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 of the counterweight after being installed in the float body, and facilitating the disassembly and assembly of the anti-evaporation float during maintenance.

[0023] 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 evaporation-resistant 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 evaporation-resistant float; an empty groove for preventing frost heave pre-deformation in winter is provided on the side wall of the counterweight body, 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 evaporation-resistant float remains unchanged in winter.

[0024] 7. In the present invention, a plurality of fixing ribs with a thickness of 2 mm are arranged on the top of the counterweight body, which ensures that when the counterweight body is inserted into the float body, the fixing ribs can be matched 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.

[0025] 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 limited by the space of the float body.

[0026] 9. In the present invention, the weight of the counterweight after 90-95% of the volume of the hindered evaporation liquid is injected is equal to the displacement of the float body when it floats on the hindered evaporation liquid. 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 weight (Gwater displacement = Gfloat). The fixed counterweight with no center of gravity offset and no weight change arranged inside the evaporation-resistant float can keep the center of gravity of the 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 that the non-fixed liquid counterweight in the conventional float flows due to the action of external force, causing the center of gravity to shift or even invert, forming a new center of gravity, and the float is subjected to force redistribution, thereby causing the problem of reversal, erection, half-lying floating or even stacking.

Detailed implementation manners

[0028] It should be noted that the terms "including" and "having" and any variations thereof in the description and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is 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 construed as a limitation of the present invention.

[0030] In addition, 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 quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a number of" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: As Figure 1 , Figure 2 , Figure 3 shown, an evaporation-resistant float that prevents irregular floating and can automatically reset includes a hollow flying-saucer-shaped float body, a counterweight 1 fixedly arranged at the central position inside the float body, and a port sealing cover 3 for fixing the counterweight 1; the outer periphery of the float body is a regular hexagon structure; the float body is a vertically symmetric structure; 90-95% by volume of evaporation-resistant liquid is injected into the counterweight 1, and the specific gravity remains unchanged.

[0032] Specifically, the float body is set as an integrally blow-molded (or injection-molded) overall structure with a hollow flying-saucer shape and a regular hexagon outer periphery, and is symmetrically arranged up and down. The material used is HDPE (or PET), so that the wall thickness of the upper cover body 2 and the lower cover body 5 can be ensured to be uniform during injection molding (or blow molding) of the float body, the strength of the upper cover body 2 and the lower cover body 5 is consistent, the service life is consistent, the structure is simple, and the service life of the evaporation-resistant float is guaranteed; the regular hexagon structure setting ensures that each individual unit of the evaporation-resistant floats placed on the water surface can be freely assembled and fitted to each other (without setting a connecting device), there will be no gaps, which is beneficial to forming a continuous water body protection layer for evaporation resistance on the water surface (i.e., a covering body covering the reservoir water surface); the thickness of the float body is consistent with the material, which ensures that the service life is consistent during the operation of the evaporation-resistant float.

[0033] The counterweight 1 is set as a cylindrical barrel structure formed in one piece (similar to a mineral water bottle), made of HDPE (or PET), and filled with a blocked evaporation liquid counterweight accounting for 90 - 95% of its volume, so that the counterweight 1 forms a solid core integral structure and is fixed at the center inside the hollow float body. That is, the center of gravity of the blocked evaporation float is fixed at the center inside, and the center of gravity remains unchanged. When the wind and waves come, the blocked evaporation float will drift up and down with the wind and waves. Due to the setting of the counterweight 1, the blocked evaporation float is always subjected to the downward gravity force in the fixed direction and orientation of the fixed center of gravity, enabling the individual blocked evaporation float to have good stability and wind resistance, and enabling the blocked evaporation float to maintain its original shape without irregular floating. Even when the blocked evaporation float is stacked or tilted due to strong winds, it can still be restricted by the fixed center of gravity and can automatically adjust its floating posture to return to the normal shielding state, enabling the blocked evaporation float to float flat in sheets on the water surface to form a covering body covering the reservoir water surface, achieving the purpose of preventing water evaporation. The blocked evaporation liquid contained in the counterweight (in this invention, it is water, and it can also be pure water) will not show phenomena such as emitting an odor or turning green because it is in a sealed state and in an anaerobic state, just like the water in a mineral water bottle will not change color no matter how long it is placed.

[0034] The above settings of the float body and the counterweight enable the blocked evaporation float to maintain an effective shielding surface for a long time, which can be said to achieve maintenance-free use and effectively reduce the later maintenance cost.

[0035] Furthermore, as Figure 1 、 Figure 2 、 Figure 3 shown, the float body is integrally formed, including a floating ring 4 with a regular hexagon structure on the outer periphery floating on the water surface, an arc-shaped upper cover body 2 arranged on the floating ring 4, and an arc-shaped lower cover body 5 arranged under the floating ring 4; the upper cover body 2 and the lower cover body 5 are symmetrically arranged, and the arcs, thicknesses, and materials of the upper cover body 2 and the lower cover body 5 are the same. The floating ring 4 has a certain height (generally greater than 5 cm), with an upper edge line and a lower edge line. The lower edge line is the water level line when the blocked evaporation float floats on the water surface. It should be noted that: when the blocked evaporation float is turned over for use, the upper edge line and the lower edge line mentioned here are reversed.

[0036] Furthermore, the elevation angles of the arcs of the upper cover body 2 and the lower cover body 5 are both not less than 10°, so that when the blocked evaporation float is stacked up by wind and waves, it can also quickly slide down, thus ensuring that the blocked evaporation float can float in sheets on the water surface to form a covering body covering the reservoir water surface.

[0037] Furthermore, several protruding card slots 2-1 for fixing the counterweight 1 are arranged at the top end of the upper cover body 2; a cylindrical groove 5-1 for clamping the counterweight 1 is arranged at the bottom end of the lower cover body 5.

[0038] Furthermore, the protruding height of the card slot 2-1 is 2 mm. When the float body is integrally blow-molded (or injection-molded), due to the influence of the existing blow-molding process, the protruding height of the card slot 2-1 can only be consistent with the thickness of the float body (the thickness is 2 mm).

[0039] Furthermore, a port fixing thread 5-2 matching the port sealing cover 3 is arranged 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 1, ensuring the sealing performance of the float body structure and preventing water from entering the float body.

[0040] Furthermore, the counterweight 1 is a cylindrical barrel structure formed integrally. A liquid injection port 1-2 and a sealing cover body are arranged at the bottom end of the counterweight 1; a plurality of empty grooves 1-3 for preventing pre-deformation due to winter freeze-thaw are arranged on the side wall of the counterweight 1; when the top end of the counterweight 1 touches and fits with the top end of the float body, a plurality of fixing ribs 1-1 are arranged at the top end of the counterweight 1.

[0041] Furthermore, the thickness of the fixing rib 1-1 is 2 mm, which ensures that when the counterweight is inserted into the float body, the fixing rib can fit with the card slot on the upper cover body, further ensuring the fixed position of the counterweight and effectively ensuring the stability of the center of gravity of the evaporation-resistant float.

[0042] 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.

[0043] Furthermore, the weight of the counterweight 1 after injecting 90-95% of its volume of the evaporation-resistant liquid is equal to the displacement of the float body when it floats on the evaporation-resistant liquid.

[0044] Specifically, the weight of the counterweight 1 after injecting 90-95% of its volume of the evaporation-resistant liquid is equal to the displacement of the float body when it floats on the evaporation-resistant liquid, that is, the weight of the float body, the counterweight 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 evaporation-resistant float floats on the water surface, the water level line cannot exceed the lower edge line of the floating ring 4 (at any time).

[0045] According to Archimedes' principle, after the evaporation-resistant float is thrown into the water surface, the weight of the discharged water = the buoyancy of the float (G_water_discharged = G_float). The fixed counterweight with no center-of-gravity shift and no weight change arranged 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 comes from during the impact of wind and waves. It effectively solves the problems of the conventional float, such as the non-fixed liquid counterweight flowing due to external force, resulting in a center-of-gravity shift or even inversion to form a new center of gravity, and the float's force being redistributed, thus causing problems such as inversion, erection, semi-lying floating or even stacking.

[0046] 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 them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and 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 various embodiments of the present invention.
