Description

[0001] This utility model claims priority to Chinese Patent No. 202410833129.4, filed on June 26, 2024. Technical Field

[0002] This utility model belongs to the field of water conservation technology for water resource protection, specifically relating to an anti-evaporation float that is particularly suitable for reducing water evaporation in reservoirs in arid regions. Background Technology

[0003] To reduce ineffective evaporation of water in reservoirs in arid regions, research was conducted on:

[0004] 1. Chinese patent application No. 201510135086.3, publication number CN104727269A discloses a benzene plate covering structure for reducing ineffective evaporation. Specifically, holes are provided at the edges of the benzene plate, which consists of a bottom layer, a benzene plate layer, and a top layer. Connecting devices are used to connect several benzene plates through these holes, forming a benzene plate covering structure that covers the surface of a reservoir, thereby reducing ineffective evaporation. 2. Chinese patent application No. 201610231134.3, publication number CN 105862655A discloses a method for preventing reservoir evaporation by laying floating solar panels. Whether using polystyrene panels for covering or laying floating solar panels to prevent reservoir evaporation, the need to connect the panels through a connecting mechanism, while achieving some of the purpose, has drawbacks such as large joint gaps and complex construction. In addition, the covering structure made of polystyrene panels or solar panels is lightweight and easily blown over by the wind, making it difficult to meet the usage conditions for water surfaces and lakes that are prone to wind.

[0005] 2. Chinese patent application No. 201910489211.9 and publication No. CN 110258438 A discloses a system for preventing reservoir evaporation by using flake graphite powder to lay on the surface of the reservoir to form a discontinuous graphite powder film.

[0006] 3. Chinese patent application No. 201610973174.5, publication number CN N 106320260A, discloses a floating device for inhibiting algae growth and reducing water evaporation. Its structure includes a partition plate, a floating ball, a connecting rod connecting the partition plate and the floating ball, and a counterweight inside the floating ball to keep the connecting rod vertical. This floating device is also prone to being blown away, tumbling, and accumulating in the wind, making it difficult to effectively prevent water evaporation.

[0007] 4. According to television reports, it is also known that pouring a large number of round buoys into the reservoir to cover the water surface can also prevent the evaporation of the reservoir surface. However, the above-mentioned technical solutions for preventing reservoir evaporation all have defects: when using round buoys, not only is the gap rate of the joints between the spheres as high as 11%, but the spheres also roll under the action of the wind, causing the hemispheres that were originally submerged to be exposed, which increases the amount of evaporation. At the same time, strong winds can blow the round buoys onto the reservoir bank and cause them to fall, resulting in a large area of ​​water surface being exposed. Utility Model Content

[0008] The purpose of this invention is to provide an anti-evaporation float that has a simple structure, effectively prevents it from being blown over by the wind, and effectively prevents water evaporation.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] An anti-evaporation float, characterized in that it includes a pendant mechanism and a float ring mechanism disposed around its periphery and integrated therewith; the radially outer surface of the float ring mechanism is a polygonal structure capable of being spliced ​​together.

[0011] Additional technical features constituting the above-mentioned anti-evaporation float also include:

[0012] 1. The aforementioned pituitary mechanism is a water-filled cylindrical hollow structure with a water inlet at the bottom and an exhaust vent at the top or its side.

[0013] 2. A one-way valve mechanism is provided at the water inlet to prevent water from being discharged through it;

[0014] 3. A counterweight mechanism is provided at the bottom of the structure constituting the pituitary mechanism;

[0015] 4. The axial section of the plumb bob mechanism is a curved surface structure, and the water inlet is located at the bottom of the curved surface structure;

[0016] 5. The aforementioned pituitary mechanism is a solid cylindrical structure;

[0017] 6. The aforementioned pituitary mechanism and the floating ring mechanism disposed around it are an integral structure;

[0018] 7. The pituitary mechanism and the floating ring mechanism arranged around it are separate structures, and a connecting mechanism is provided between the two to form a combined body.

[0019] 8. The aforementioned floating ring mechanism is composed of a sealed air ring;

[0020] 9. A pinhole for adjusting the internal air pressure is provided at the upper part of the sealing air ring;

[0021] 10. The floating ring mechanism is a solid structure made of a lightweight material capable of floating;

[0022] 11. The floating ring mechanism is a concave body with a top cover, and the pendant mechanism can be combined with the floating ring mechanism through a connecting mechanism.

[0023] 12. The top cover constituting the floating ring mechanism is an outwardly convex arc shape;

[0024] 13. Three, four, or six fixing holes for fixing the connecting mechanism are evenly arranged around the periphery of the pituitary mechanism.

[0025] 14. A radial groove for fixing the connecting mechanism is provided on the pendant mechanism constituting the fixing hole;

[0026] 15. A radial groove corresponding to the fixing hole is provided at the bottom of the floating ring mechanism for use in fixing the connection mechanism;

[0027] 16. The connecting mechanism is composed of a locking pin and a connecting rod with both ends capable of being inserted into the fixing hole;

[0028] 17. The polygonal structure described herein is a regular hexagon, a regular triangle, a regular quadrilateral, or a rectangular structure in which the longer side is twice the length of the shorter side;

[0029] 18. The thickness of the floating ring mechanism is set between 5 and 60 centimeters.

[0030] Compared with the prior art, the anti-evaporation float provided by this utility model has the following advantages: Firstly, because the structure of the anti-evaporation float consists of a pendant mechanism and a floating ring mechanism integrated with it, the floating ring mechanism can stably support the pendant mechanism on the water surface. Even in strong winds, only one side of the floating ring mechanism sinks in the water, but it still has the buoyancy to support the pendant mechanism, making it extremely difficult to be blown away, thus achieving the stability of the anti-evaporation float on the water surface. Secondly, because the outer surface of the floating ring mechanism is a polygonal structure that can be spliced, it can form a structure that floats on the water surface. Firstly, the continuous, seamless splicing structure effectively prevents water surface evaporation and features a simple structure. Secondly, because three, four, or six fixing holes are evenly arranged around the perimeter of the anti-evaporation float's pendant mechanism to secure the connecting mechanism, and the bottom of the float ring mechanism has radial grooves corresponding to the fixing holes for securing the connecting mechanism, when adjacent anti-evaporation floats are connected by the connecting mechanism, they are engaged in the radial grooves, thus achieving stability in the connection between the anti-evaporation floats. Thirdly, because the connecting mechanism connects adjacent anti-evaporation floats, it simplifies the process of deploying anti-evaporation floats on the lake surface and increases efficiency.

[0041] The following detailed description, in conjunction with the accompanying drawings, describes the steam-blocking float provided by this utility model, as well as the steam-blocking structure and working principle comprising the steam-blocking float.

[0042] like Figure 1 , 2 Figure 3 shows a schematic diagram of an embodiment of the anti-evaporation float provided by this utility model. The structure constituting the anti-evaporation float consists of a floating ring mechanism 1 formed by a hexagonal sealing air ring 16 on the outer side 12 that can be continuously and seamlessly spliced, and a pendant mechanism 2 whose axial cross-section is cylindrical and can be integrally formed with the inner side ring 11 constituting the sealing air ring 16. The pendant mechanism 2 has a water inlet hole 21 at the bottom and an air vent hole 22 at the top, which constitutes a water filling mechanism. The pendant mechanism 2 can be filled with water through the water filling mechanism, so that the anti-evaporation float floats in the water and acts as a counterweight.

[0043] When using the above-described anti-evaporation float structure to achieve surface evaporation, the float is deployed into the reservoir. Under the weight of the pendant mechanism 2, it sinks, and water enters through the inlet 21. Air in the pendant mechanism is expelled through the vent 22 until the weight of the water entering the pendant mechanism balances the buoyancy of the float ring mechanism 1, at which point the anti-evaporation float floats on the water surface. In the above-described anti-evaporation float structure, by adjusting the size of the float ring mechanism 1 (or the volume of the pendant mechanism 2, either can be adjusted), the height of the float ring mechanism 1 above the water surface (i.e., the height of the anti-evaporation float above the water surface) can be set to prevent water from overflowing from the joints of the anti-evaporation float onto the hexagonal float ring mechanism 1, thus preventing new evaporation. The radial cross-section of the float ring mechanism 1 (e.g., the height of the anti-evaporation float above the water surface) is shown in the figure. Figure 2 As shown, it is a regular hexagon (or a regular triangular, quadrilateral, or rectangular structure where the longer side is twice the length of the shorter side), thus enabling seamless splicing of all the anti-evaporation floats composed of the regular hexagonal floating ring mechanism 1 on the water surface, effectively preventing water evaporation; since the pendant mechanism constituting the anti-evaporation float is surrounded by the floating ring mechanism 1, which can be integrated with it, the floating ring mechanism can steadily support the pendant mechanism on the water surface. Even in strong winds, only one side of the floating ring mechanism sinks in the water, but it still plays a floating role, so it is extremely difficult to blow it up, thus achieving the stability of the anti-evaporation float on the water surface.

[0044] In the structure that constitutes the above-mentioned anti-evaporation float:

[0045] 1. The float ring mechanism 1 used to ensure that the anti-evaporation float floats on the water surface can be, for example, as follows: Figure 3 The sealing air ring 16 shown has an outer hexagonal shape, but it can also be as follows: Figure 4 The solid structure shown is made of a lightweight material, such as plastic foam, with an outer hexagonal shape and a density less than water (preferably an inner core 13 made of foam material wrapped in a rigid, impact-resistant plastic outer skin 14); that is, when the float mechanism is a solid structure, not only its cross-section (axial direction of the anti-evaporation float) shape (such as...) Figure 3 The shape shown is approximately circular or as shown in the image. Figure 4 The oval shape shown is easier to set up, and it is more resistant to impacts and has a longer lifespan.

[0046] 2. The plumb bob mechanism 2 constituting the above-mentioned anti-evaporation float and the floating ring mechanism 1 disposed around it can be as follows: Figure 3 The structure shown can be a one-piece structure formed by injection molding in one step, or a one-piece structure formed by bonding separate parts; it can also be as follows: Figure 4 (or Figure 2The diagram shows a separate structure consisting of a pendant mechanism 2 and a float ring mechanism 1, with connecting parts 31 and 32 that can be connected to each other on the inner ring 11 of the float ring mechanism 2 and the outer ring 23 of the pendant mechanism 2, respectively. The connecting parts 3 enable the inner ring 11 of the float ring mechanism 2 and the pendant mechanism 2 to form a combined anti-evaporation float. The manufacturing, transportation, and use (on-site assembly) of this two-part anti-evaporation float are more convenient.

[0047] 3. For example Figure 5 As shown, to facilitate the construction of the anti-evaporation float structure and effectively overcome the requirement of water evaporation through the gap between the two structures, the pendant mechanism 2 and the float ring mechanism 1, the float ring mechanism 1 is a concave body with a top cover 15, and the pendant mechanism 2 is combined with the float ring mechanism through the insertion mechanism 3. In this anti-evaporation float structure, whether the float ring mechanism 1 is composed of a top cover 15 and a sealed air ring structure 16, or a top cover 15 and a solid structure made of lightweight material, when the float ring mechanism is combined with a solid or cylindrical pendant mechanism 2 to form an anti-evaporation float, the top cover 15 of the float ring mechanism 1 effectively overcomes the problem of lake water evaporation through the gap between the pendant mechanism 2 and the float ring mechanism 1. The insertion mechanism 3, which forms the connection between the pendant mechanism 2 and the float ring mechanism 1, can be as follows: Figure 4 The connector shown, which is provided on the inner ring 11 constituting the floating ring mechanism 2 and the outer ring 23 constituting the pendant mechanism 2, can also be as follows: Figure 5 The insertion mechanism 3 shown, consisting of the insert (connector) 31 on the inner side 151 of the top cover constituting the floating ring mechanism and the connector (insert) 32 on the top of the pendant mechanism, can also be a threaded connection structure formed by the screw cylinder c1 on the floating ring mechanism 2 and the thread c2 at the corresponding position on the pendant mechanism 2 (see...). Figure 7 The two can be plugged in or threaded together to form a combined structure of an anti-evaporation float;

[0048] In such Figure 5 In the structure shown, when the axial cross section of the pendulum mechanism 2 is rectangular (cylindrical), a water inlet 21 is provided at its bottom and an air vent 22 is provided on its side. That is, when the anti-evaporation float of this structure is placed in the water, lake water enters the pendulum mechanism 2 through the water inlet 21 and the air in the pendulum mechanism is discharged through the air vent until the water-inlet pendulum mechanism and the float ring mechanism 2 reach buoyancy balance.

[0049] Once the volume (buoyancy) of the float ring mechanism 2 constituting the anti-evaporation float is set, the pendant mechanism 2 constituting the anti-evaporation float can also be set as a barrel-shaped structure with an open top (no top cover 20, and the gap between the plug-in mechanism 3 forms an exhaust hole 22) and a water inlet hole 21 at the bottom. However, the volume (water weight) of the barrel-shaped pendant mechanism should be smaller than the volume (buoyancy) of the float ring mechanism 2, so that the function of the anti-evaporation float can be realized.

[0050] When the top cover 15 constituting the above-mentioned floating ring mechanism is in the shape of an outwardly convex arc 152, its structural strength is higher.

[0051] 4. When the thickness (height) H of the float ring mechanism is set at 5-60 cm, the hexagonal float rings on the outer sides are squeezed together, allowing all the anti-evaporation floats to achieve a seamless splicing. Because there is a 5-60 cm height difference between the water surface and the top of the anti-evaporation floats, it effectively prevents wind from creating waves that could blow the floats over, thus effectively preventing water evaporation. Simultaneously, for the float ring mechanism, whether it is a solid structure made of lightweight materials or a sealed air ring structure 16, the buoyancy is relatively reduced when its height is less than 5 cm. To form a suitable anti-evaporation float, its diameter must be increased. Large-diameter anti-evaporation floats are not only costly to manufacture but also difficult to install and transport. When its height is greater than 60 cm, the anti-evaporation floats will protrude too high above the water surface, increasing the wind resistance on the sides and causing them to be unable to float stably on the water surface.

[0052] 5. When the pituitary mechanism 2 functions as a pituitary (counterweight) through water filling, such as... Figure 3 When using a cylindrical structure (axial cross-section shown), in order to allow the anti-evaporation float placed on the water surface to sink quickly and complete the installation as soon as possible, simply filling water through the water inlet 21 located at the bottom of the plumb bob mechanism would take a long time. Therefore, if... Figure 6 The above-mentioned pendulum mechanism 2 is configured such that its axial cross-section is an arc-shaped spherical surface, and the water inlet 21 is located at the center of the bottom of the arc-shaped spherical surface; of course, it can also be (e.g.) Figure 5 , 6 As shown, by setting a counterweight mechanism 24 at the bottom of the cylindrical structure or the arc-shaped spherical pendant mechanism, the steam-resistant float can also sink quickly, so as to complete the installation and construction requirements as soon as possible.

[0053] 6. To achieve the interconnection of the aforementioned hexagonal float ring mechanism on the outer surface, and to ensure seamless splicing of all anti-evaporation floats, as follows: Figure 6 , 7 As shown in Figure 8, six fixing holes 25 are evenly arranged around the periphery of the pendant mechanism 2, which can be used to fix the connecting mechanism. Figure 6 , 7The connecting mechanism 4, consisting of an expanded turtle head (inserted into the fixing hole 25 and opened and locked) 41 and a connecting rod 42 at both ends, connects and fixes adjacent anti-evaporation floats A and B together; to prevent misalignment between the adjacent anti-evaporation floats when blown by the wind on the lake surface, a central groove 26 is provided at the bottom of the plumb bob mechanism (as shown in the figure). Figure 7 , 8 As shown), the fixing hole 25 is provided in the groove, and a corresponding radial groove 27 is provided in the radial direction corresponding to the fixing hole 25. The connecting rod 42 is inserted into the groove, so that the two anti-evaporation floats connected together are effectively fixed and can prevent misalignment between them.

[0054] like Figure 9 As shown, when the positions of the six fixing holes 25 located around the perimeter of the pituitary mechanism 2 are higher than the height of the floating ring mechanism 1 (also applicable to...), Figure 6 When the diaphragm mechanism is configured such that its axial cross section is an arc-shaped spherical surface and the fixing hole 25 is higher than the float ring mechanism 1), a radial groove 17 corresponding to the fixing hole 25 of the fixing connection mechanism 4 is provided at the bottom of the float ring mechanism 1. The expansion heads 41 provided at both ends of the connection mechanism 4 are respectively inserted into the corresponding fixing holes 25 of the two adjacent anti-evaporation float diaphragm mechanisms, and at the same time the connecting rod 42 is inserted into the radial groove 17 of the two adjacent float ring mechanisms A and B, so that the two anti-evaporation floats can be effectively fixed.

[0055] 7. When structure 2 constituting the pituitary mechanism is a hollow cylindrical structure, after the anti-evaporation float is placed on the water surface, lake water will enter the hollow cylindrical structure through its inlet 21. When the wind blows and the anti-evaporation float swings (or sways) on the lake surface, it prevents water from the pituitary mechanism from being discharged through the inlet, thus reducing the weight of the pituitary mechanism and affecting its counterweight effect. Ideally, the water should be placed at the inlet 21 in the hollow cylindrical structure (e.g., Figure 3 As shown, a rubber sheet fixed to the inner wall of the device serves as a one-way valve mechanism 28. When the anti-evaporation float is placed on the water surface, it sinks under its own weight. Lake water flows through the inlet hole and pushes open the rubber sheet, entering the pendant mechanism. When the anti-evaporation float swings (or sways), water in the pendant mechanism is discharged through the inlet hole. The rubber sheet 28, under water pressure, covers the inlet hole 21, thus preventing water from draining out of the pendant mechanism and ensuring its stable counterweight function. Alternatively, the one-way valve mechanism can also be configured as follows: Figure 10 The device shown consists of a sealing assembly 281 that can seal the inlet hole 21 (which may have multiple small inlet holes), an outer support assembly 283 that prevents the sealing assembly 281 from uncontrollably entering the pendant mechanism during water intake (its length is greater than the diameter of the inlet hole), and a connecting rod 282 that passes through the inlet hole (central hole) 21 and connects the two. It also functions as a one-way valve mechanism 28. A simpler version is... Figure 6As shown, a sphere with a density slightly greater than that of water and a diameter larger than that of the outlet hole 21 is set inside the pendant mechanism whose axial cross section is an arc-shaped spherical surface. This can also realize the function of a one-way valve mechanism 28 that prevents water from draining outward from the inlet hole.

[0056] 8. When the floating ring mechanism constituting the above-mentioned anti-evaporation float is a sealed air ring 16, since the anti-evaporation float is generally used in Xinjiang, where the temperature difference between summer and winter is large, the highest temperature in summer can reach 60 degrees Celsius and the lowest temperature in winter can drop to -30 degrees Celsius, in order to reduce the damage caused by thermal expansion and contraction of the air in the sealed air ring 16 and maintain the balance of its internal air pressure, a pinhole 18 for adjusting its internal air pressure is provided at the upper part of the sealed air ring 16 (e.g., Figure 3 , 6 (as shown in 9); there can be multiple pinholes, but their diameter is generally selected between 0.5 and 1.5 mm. Since lake water or rainwater will generate tension on the surface of the sealing air ring 16, water will not enter through the pinhole 18 and affect the function of the sealing air ring 16 in generating buoyancy.

[0057] 9. The plumb bob mechanism 2, used to ensure the anti-evaporation float sinks into the water and acts as a counterweight, can be as follows: Figure 3 , 4 The cylindrical hollow structure shown in 5 and 7, which can form a counterweight function by filling water through its water inlet 21, can also be as follows: Figure 9 The solid structure shown has a certain weight. Due to the floating ring mechanism 1 around its perimeter, the entire anti-evaporation float can float on the water surface and ensure that it will not be blown over by the wind. Of course, in the structure of this anti-evaporation float, based on the weight of the solid body constituting the pendant mechanism 2, the size of the hexagonal floating ring mechanism 1 fixed to its perimeter is designed according to the principle of buoyancy to ensure that the anti-evaporation float can float stably on the water surface.

[0058] 10. The float ring mechanism constituting the above-mentioned anti-evaporation float is preferably a regular hexagon, which is not only relatively simple in terms of manufacturing process (the blow molding process of forming a regular hexagonal outer side and a circular air sealing ring 16 formed inside), but also simple in terms of assembly process on the water surface. Of course, it can also be set as a regular triangular, regular quadrilateral or a rectangular structure where the long side is twice the length of the short side. At the same time, the radial cross section of the matching pendant mechanism can be set as a corresponding shape or a circle. The number of fixing holes 25 set around the pendant mechanism also corresponds to the number of sides (3 sides, 4 sides) of the regular triangular, regular quadrilateral or rectangular structure where the long side is twice the length of the short side, so as to facilitate the fixed connection between adjacent anti-evaporation floats through the connecting mechanism 4.
