Technical Field
[0001] This utility model relates to the field of evaporation suppression technology for evaporation ponds, and in particular to a float-type evaporation suppression and covering device for evaporation ponds. Background Technology
[0002] In arid and semi-arid regions, water resources are already extremely scarce. As an important facility for water resource recycling and treatment, evaporation ponds face particularly prominent issues of ineffective evaporation. These regions typically have dry climates, strong sunlight, strong winds, and high evaporation rates, resulting in significant water loss from evaporation ponds due to natural evaporation. This not only reduces water resource utilization efficiency but also increases the difficulty and cost of water replenishment. Traditional evaporation suppression methods for evaporation ponds, such as using chemical reagents, biological covering, or simple physical shielding, can reduce evaporation to some extent, but they often have drawbacks such as unstable effectiveness, potential environmental impacts, and high costs. Simple physical shielding may not be effective in coping with complex wind and wave conditions, is prone to capsizing, and is difficult to adjust the evaporation suppression efficiency in a timely manner according to real-time external conditions, thereby reducing the amount of ineffective evaporation and affecting water resource utilization.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0034] Example 1
[0035] Reference Figures 1-5This is the first embodiment of the present invention. This embodiment provides a float-linked evaporation tank anti-evaporation covering device. The float-linked evaporation tank anti-evaporation covering device includes a main component 1, including a pole 11. A base 12 is fixed to the bottom of the pole 11. The base 12 is used with bolts to fix the pole 11 to the bottom of the evaporation tank. A ground nail 13 is fixed below the base 12. The ground nail 13 increases the stability of the pole 11 fixed to the bottom of the evaporation tank. A covering cloth 14 is provided on the pole 11. The covering cloth 14 has a certain elasticity and is used to cover the water body, thereby increasing the anti-evaporation coverage area. In the initial state, the covering cloth 14 is in a naturally contracted state.
[0036] Adjustment component 2, located on pole 11, includes a slider 21. A floating component 22 is rotatably connected to one side of the slider 21. The slider 21 is used to control the expansion of the cover 14, while the floating component 22 can dynamically adjust the anti-evaporation coverage area according to the height of the water body.
[0037] The sliding component 21 includes a lifting sleeve 211 that slides outside the upright 11. The upright 11 has a lifting groove 11-1. The lifting sleeve 211 can slide a distance on the upright 11 that is close to the upper part of the upright 11. The distance that the lifting sleeve 211 can slide on the upright 11 is the length of the lifting groove 11-1. In the initial state, when the water height does not exceed the base 12, the position of the lifting sleeve 211 corresponds to the bottom of the lifting groove 11-1.
[0038] A rotating plate 212 is hinged to one side of the lifting sleeve 211, and a follower plate 213 is provided on one side of the rotating plate 212. A first cylinder 214 is slidably arranged inside the rotating plate 212, and a second cylinder 215 is fixed on the follower plate 213. A rotating sleeve 216 is connected to the rotating plate 212 by a bearing on one side. The cooperation of the first cylinder 214, the second cylinder 215 and the rotating sleeve 216 can change the overall length of the rotating plate 212 and the follower plate 213, which facilitates further expansion of the evaporation suppression coverage area in strong wind environments.
[0039] There are six sets of rotating plates 212, follower plates 213 and intermediate connecting parts, and six sets of floating parts 22, each corresponding to a floating part 22.
[0040] The first cylinder 214 has a protrusion at one end, and the rotating plate 212 has a corresponding groove, which restricts the first cylinder 214 from rotating relative to the rotating plate 212 and only allows it to slide in a straight line within it.
[0041] The floating component 22 includes a rotating shaft 221 rotatably connected to the follower plate 213. A float 222 and a counterweight 223 are bolted to the rotating shaft 221. The cover 14 is circular and has a through groove inside. The middle part of the cover 14 is fixed to the lifting sleeve 211, and the edge of the cover 14 is fixed to the follower plate 213.
[0042] In the initial state, when the water level does not exceed the base 12, the position of the lifting sleeve 211 corresponds to the bottom of the lifting trough 11-1. Gravity causes the counterweight 223 to fit against the base 12, and the cover 14 is in a naturally contracted state. The position corresponding to the top of the lifting trough 11-1 is the safe liquid level line of the evaporation pool. When the water level exceeds the top of the lifting trough 11-1, it is necessary to reduce the evaporation suppression coverage area to increase the evaporation rate and bring the water back to the safe liquid level.
[0043] Under the buoyancy of the water, the float 222 will float on the water surface. As the water height increases, the float 222 will drive one end of the follower plate 213 to move upward. At this time, the relative position of the rotating plate 212 and the follower plate 213 is restricted and will not change. Moreover, the two are closest at this time, which will change the angle between the rotating plate 212 and the follower plate 213 and the upright 11, thereby causing the cover 14 to open, thereby increasing the evaporation suppression coverage area and reducing the ineffective evaporation.
[0044] When the cover 14 is fully opened, but not stretched, and the water level continues to rise, the lifting sleeve 211 will move upward in sync, and the cover 14 will remain fully open. When the lifting sleeve 211 moves to the highest position of the lifting trough 11-1, it cannot move further. If the water level continues to rise, the float 222 will move the edge of the cover 14 upward, eventually causing the cover 14 to contract again, reducing the evaporation suppression coverage area and improving evaporation efficiency.
[0045] Example 2
[0046] Reference Figure 2 , Figure 3 and Figures 5-8 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0047] Specifically, the adjustment component 2 also includes a length adjustment component 23. By setting the length adjustment component 23, when the cover 14 is already open, the evaporation efficiency of the water will be increased in the event of a strong wind. At this time, the overall length of the rotating plate 212 and the follower plate 213 is increased, so that the cover 14 is stretched and the area of the water covered is expanded, thereby increasing the evaporation suppression coverage area and reducing the amount of ineffective evaporation.
[0048] The length adjusting component 23 includes a first slider 231 fixed on the first cylinder 214, a first spiral groove 216-1 opened on the rotating sleeve 216, the first slider 231 sliding in the first spiral groove 216-1, a second spiral groove 216-2 opened on the rotating sleeve 216, and a second slider 232 fixed on the second cylinder 215, the second slider 232 sliding in the second spiral groove 216-2.
[0049] When the first cylinder 214 slides towards the upright 11 within the rotating plate 212, the first slider 231 slides within the first spiral groove 216-1, thereby causing the rotating sleeve 216 to rotate. When the rotating sleeve 216 rotates, the second slider 232 also slides within the second spiral groove 216-2, causing the second cylinder 215 to move away from the first cylinder 214, thereby increasing the overall length of the rotating plate 212 and the follower plate 213, which stretches the cover 14 and expands the area of water coverage.
[0050] Specifically, a rectangular groove 214-1 is provided on the first cylinder 214, and a rectangular block 233 is fixed on one side of the second cylinder 215. The rectangular block 233 slides in the rectangular groove 214-1. Through the cooperation of the two, the second cylinder 215 is restricted from rotating relative to the first cylinder 214.
[0051] Specifically, the adjustment component 2 also includes a trigger 24 located on the pole 11. In strong wind conditions, the length adjustment component 23 can be triggered to further expand the anti-evaporation coverage area.
[0052] The trigger 24 includes a wind vane 241 connected to the top of the pole 11 by a bearing. A rotating frame 242 is fixed to the bottom of the wind vane 241. A vertical plate 243 is rotatably connected inside the rotating frame 242. A bracket is connected to the outer bearing of the wind vane 241. The bracket is U-shaped and fixed to the pole 11, thereby supporting the wind vane 241 and the rotating frame 242. A torsion spring is provided at the position where the vertical plate 243 is rotatably connected to the rotating frame 242. Under the action of the torsion spring, the vertical plate 243 will be perpendicular to the ground.
[0053] In windy conditions, the wind vane 241 will drive the rotating frame 242 to rotate, causing the upright plate 243 to rotate to the windward direction. In strong wind conditions, the upright plate 243 will overcome the force of the torsion spring and rotate downward.
[0054] A support column is fixed at the bottom of the rotating frame 242, and the support column is connected to the top bearing of the rotating column 246.
[0055] Specifically, a lifting frame 244 is slidably installed inside the upright 11. A spring piece 245 is installed at the bottom of the lifting frame 244. The other end of the spring piece 245 is fixed inside the upright 11. Several openings are provided on the side of the lifting frame 244 to prevent obstruction of the wind from exerting force on the upright plate 243. The spring piece 245 applies an upward pushing force to the lifting frame 244.
[0056] In a strong wind environment, the upright plate 243 rotates downward and contacts the upper end of the lifting frame 244, thereby causing the lifting frame 244 to move downward, the spring piece 245 is compressed, the lifting frame 244 is fixed with a protrusion, and the upright plate 243 is provided with a corresponding groove, thereby restricting the lifting frame 244 from rotating and only allowing it to lift vertically.
[0057] Example 3
[0058] Reference Figures 5-9 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0059] Specifically, the upright 11 has a bearing connected to a rotating column 246. The upper end of the rotating column 246 has a third spiral groove 246-1. The rotating column 246 is inserted into the lifting frame 244. A third slider 247 is fixed on the lifting frame 244.
[0060] In strong wind conditions, when the lifting frame 244 moves downward, the third slider 247 slides in the third spiral groove 246-1, which drives the rotating column 246 to rotate.
[0061] Specifically, a disc 248 is slidably mounted on the rotating column 246, and a pull rope 249 is fixed on the disc 248. The other end of the pull rope 249 is fixed to the first column 214. The disc 248 has a protrusion, and the rotating column 246 has a vertical groove corresponding to the protrusion, so that the disc 248 can slide vertically along the rotating column 246, but the two can rotate synchronously.
[0062] When the rotating column 246 rotates, it drives the disc 248 to rotate synchronously. The pull rope 249 will wrap around the surface of the disc 248, thereby driving the first column 214 to slide towards the upright 11 inside the rotating plate 212.
[0063] The rotating plate 212 is hollow inside, and the two sides of the rotating plate 212 are hinged to the lifting sleeve 211, so as to avoid affecting the large pull on the pull rope 249 when the rotating plate 212 rotates.
[0064] Specifically, the top bearing of the disc 248 is connected to an annular plate 2410, and an L-shaped plate 2411 is fixed on the annular plate 2410. The L-shaped plate 2411 is fixed on the lifting sleeve 211. The width of the lifting groove 11-1 corresponds to the L-shaped plate 2411. The L-shaped plate 2411 slides in the lifting groove 11-1. There are a total of six sets of these two, which correspond to some structures of the floating part 22 and the sliding part 21.
[0065] By setting up the annular plate 2410 and the L-shaped plate 2411, the lifting of the lifting sleeve 211 can synchronously drive the disc 248 to lift, ensuring that the relative height between the two remains constant.
[0066] Specifically, a limiting block 2412 is fixed inside the upright 11, and a limiting groove 248-1 is opened on the disc 248. The limiting block 2412 and the limiting groove 248-1 are used to limit the rotation of the disc 248, that is, to limit the change in the overall length of the rotating plate 212 and the follower plate 213. When the liquid level is very low or the liquid level exceeds the safe liquid level, the anti-evaporation coverage area will not be increased in a strong wind environment.
[0067] Specifically, there are two limit blocks 2412. The upper and lower end faces of the disc 248 are provided with corresponding limit grooves 248-1. The two limit blocks 2412 are located on the highest end face and the lowest end face of the lifting groove 11-1, respectively. The upper limit block 2412 is longer and the lower limit block 2412 is shorter.
[0068] When in use, the upright 11 is fixed to the bottom of the evaporation tank with bolts. In the initial state, when the water level does not exceed the base 12, the position of the lifting sleeve 211 corresponds to the bottom of the lifting groove 11-1. Gravity causes the counterweight 223 to fit against the base 12, and the cover 14 is in a naturally retracted state.
[0069] As the liquid level rises, the float 222 floats on the water surface under the buoyancy of the water. As the water level increases, the float 222 will drive one end of the follower plate 213 to move upward. At this time, the relative position of the rotating plate 212 and the follower plate 213 is restricted and will not change, so that the angle between the rotating plate 212 and the follower plate 213 and the upright 11 will change, thereby causing the cover 14 to open, increasing the evaporation suppression coverage area and reducing the ineffective evaporation. After the cover 14 is fully opened, if the water level continues to rise, it will drive the lifting sleeve 211 to move upward in sync. The cover 14 will remain fully open, reducing the ineffective evaporation. When the lifting sleeve 211 moves to the highest position of the lifting trough 11-1, the liquid level reaches the safe height of the evaporation tank. If the liquid level is exceeded, it is necessary to control the liquid level. If the water level continues to rise, the float 222 will drive the edge of the cover 14 to continue to rise, eventually causing the cover 14 to contract again, reducing the evaporation suppression coverage area and improving the evaporation efficiency.
[0070] When encountering strong winds, water evaporation accelerates, thus requiring an increased anti-evaporation coverage area to reduce evaporation efficiency. Under the influence of strong winds, the wind vane 241 will drive the rotating frame 242 to rotate, causing the upright plate 243 to rotate to the windward direction. In strong winds, the upright plate 243 will overcome the force of the torsion spring and rotate downwards. As the upright plate 243 rotates downwards, it contacts the upper end of the lifting frame 244, causing the lifting frame 244 to move downwards. The spring 245 is compressed. When the lifting frame 244 moves downwards, the third slider 247 slides within the third spiral groove 246-1, driving the rotating column 246 to rotate. When the rotating column 246 rotates, it drives the disc 248 to rotate synchronously, and the pull rope 249 will wrap around... The surface of the disc 248 causes the first cylinder 214 to slide towards the upright 11 within the rotating plate 212. The first slider 231 slides within the first spiral groove 216-1, thereby causing the rotating sleeve 216 to rotate. When the rotating sleeve 216 rotates, the second slider 232 also slides within the second spiral groove 216-2, causing the second cylinder 215 to move away from the first cylinder 214. This increases the overall length of the rotating plate 212 and the follower plate 213, stretching the cover 14 and expanding the area covered by the water. When the airflow decreases, the spring 245 causes the lifting frame 244 to reset, restoring the overall length of the rotating plate 212 and the follower plate 213 to its initial state.
[0071] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
