Description

Technical Field

[0001] This utility model relates to the technical field of anti-evaporation devices, and in particular to a floating dish, a floating device and an anti-evaporation system. Background Technology

[0002] Evaporation occurs on the surface of reservoirs due to factors such as the sun and atmosphere, especially in arid northern regions, where evaporation results in significant water loss. Pumped storage power stations typically have two reservoirs, one upper and one lower, with a large water area. Some power stations, particularly in northern regions, lack sufficient natural water replenishment and must purchase water from other sources, paying water resource taxes as needed. For example, a pumped storage power station in Gansu Province experiences annual evaporation of 2 million cubic meters from its upper and lower reservoirs, almost one-fifth of the single reservoir's capacity. The need for replenishment during equipment operation incurs substantial annual costs. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a floating disc, a floating device and an anti-evaporation system to solve the problem of water loss caused by evaporation in reservoirs.

[0004] Based on the above objectives, this utility model provides a floating disc, including an integrally connected first structural part and a second structural part. The first structural part and the second structural part arch outwards in directions away from each other, so that the outer surfaces of the first structural part and the second structural part form arc surfaces, and the inner surfaces of the first structural part and the second structural part enclose each other to form a sealed cavity.

[0005] Furthermore, the first structural portion and / or the second structural portion includes a connected main body portion and an edge portion, wherein the edge portion is located on the periphery of the main body portion; On the first center surface, a turning connection point is formed between the main body and the edge portion, an edge point is formed on the side of the edge portion away from the turning connection point, an arched arc is formed between the two turning connection points, and a transition arc is connected between the turning connection point and the adjacent edge point. The transition arc is lower in arch height than the arched arc. Wherein, the first center plane is the center plane of the floating dish in the height direction.

[0006] Furthermore, the height of the floating dish is 0.5-1 meter, and the diameter of the floating dish is 3-5 meters.

[0007] Furthermore, the diameter of the first and second structural parts is 3-5 meters, and the diameter of the main body is 2.5-4.5 meters.

[0008] Based on the same inventive concept, this application also provides a floating device, including a plurality of floats as described above, the floats being laid on the water surface, with at least a portion of the floats having two adjacent floats in contact.

[0009] Furthermore, the edges of two adjacent floating dishes are arranged to be in relative contact or staggered contact. The edge of the floating disc is the edge of the first structural part and / or the edge of the second structural part.

[0010] Furthermore, the plurality of said floating dishes includes a first floating dish, a second floating dish, and a third floating dish, wherein the first floating dish, the second floating dish, and the third floating dish have different diameters.

[0011] Based on the same inventive concept, this application also provides an anti-evaporation system, including the floating device and the intercepting net as described above. The floating device is used to float on the water surface of the reservoir, and the intercepting net is used to be located at the water outlet of the reservoir to intercept the floating device. The width of the intercepting net is adapted to the water outlet, and the height of the intercepting net is higher than the height of the water outlet.

[0012] Furthermore, at least one first connector is provided on each of the two sides of the water outlet, and at least one second connector is provided on the bottom surface of the water outlet. The two sides of the interception net are respectively connected to the first connectors on the two sides of the water outlet, and the bottom surface of the interception net is connected to the second connector.

[0013] Furthermore, the anti-evaporation system also includes at least one support rod, which is connected to the interception net, and the bottom end of the support rod is connected to the second connector.

[0014] As can be seen from the above description, the present invention provides a floating dish, a floating device, and an anti-evaporation system. The floating dish includes an integrally connected first structural part and a second structural part. The first and second structural parts arch outwards in mutually distancing directions, so that the outer surfaces of the first and second structural parts form arc surfaces, and the inner surfaces of the first and second structural parts enclose a sealed cavity. The floating dish provided by this application has a structure with a sealed cavity, enabling it to float on the water surface and act as a shield, thereby preventing sunlight from accelerating the evaporation rate of water, thus reducing the evaporation rate and water loss. Furthermore, the floating arrangement of the floating dish on the water surface can also absorb evaporated water vapor, which is beneficial for condensation and return to the water surface, preventing water vapor loss and further reducing water loss.

[0020] Evaporation occurs on the surface of reservoirs due to factors such as the sun and atmosphere, especially in arid northern regions, where evaporation results in significant water loss. Pumped storage power stations typically have two reservoirs, upper and lower, with a large water area. Some power stations, especially in northern regions, lack sufficient natural water replenishment sources and must purchase water from other sources, paying water resource taxes as needed. For example, a pumped storage power station in Gansu Province experiences annual evaporation of 2 million cubic meters from its upper and lower reservoirs, almost one-fifth of the single reservoir's capacity. The need for water replenishment for equipment operation incurs substantial annual costs, increasing reservoir maintenance costs.

[0021] Based on this, this application proposes a floating dish, a floating device, and an anti-evaporation system to cover the water surface of a reservoir, reduce water loss in the reservoir, and thus reduce the maintenance cost of the reservoir.

[0022] In some embodiments, a floating dish 100, such as Figure 1 and Figure 2 As shown, it includes a first structural part 110 and a second structural part 120 integrally connected. The first structural part 110 and the second structural part 120 arch outwards in directions away from each other, so that the outer surfaces of the first structural part 110 and the second structural part 120 form arc surfaces, and the inner surfaces of the first structural part 110 and the second structural part 120 enclose and form a closed cavity 130.

[0023] Specifically, the first structural part 110 and the second structural part 120 together form a closed cavity 130 structure, which floats on the water surface and blocks the water surface, thereby reducing the water evaporation rate. In addition, the outer surfaces of the first structural part 110 and the second structural part 120 are both curved, so that the connection between the first structural part 110 and the second structural part 120 is above the water surface. Thus, the side of the float 100 near the water surface can absorb the evaporated water vapor and prevent water loss due to evaporation.

[0024] It should be noted that the first structural part 110 and the second structural part 120 are made of the same material, which can be plastic or other materials with a density lower than that of water and which are high-molecular-weight anti-aging materials.

[0025] In this embodiment, the float 100 has a structure with a sealed cavity 130, which can float on the water surface and block the water surface, thereby preventing sunlight from hitting the water surface and accelerating the evaporation rate of water. This helps to reduce the evaporation rate and reduce water loss. Furthermore, the floating arrangement of the float 100 on the water surface can also absorb the evaporated water vapor, which is conducive to the condensation of water vapor and its return to the water surface, preventing water vapor loss and further reducing water loss, thus helping to reduce water loss.

[0026] In some embodiments, such as Figure 2As shown, the first structural portion 110 and / or the second structural portion 120 include a main body portion 121 and an edge portion 122 connected to each other, wherein the edge portion 122 is located on the periphery of the main body portion 121; On the first center surface, a turning connection point 123 is formed between the main body portion 121 and the edge portion 122. An edge point 124 is formed on the side of the edge portion 122 away from the turning connection point 123. An arched arc 125 is formed between the two turning connection points 123. A transition arc 126 connects the turning connection point 123 and the adjacent edge point 124. The transition arc 126 has a lower arch height than the arched arc 125. Wherein, the first center plane is the center plane of the floating plate 100 in the height direction.

[0027] Specifically, at least one of the first structural portion 110 and the second structural portion 120 includes a connected main body portion 121 and an edge portion 122, and a turning connection point 123 is formed between the main body portion 121 and the edge portion 122 on the first center surface of the floating dish 100. On the first center surface, an arched arc 125 is formed between two of the turning connection points 123, and a transition arc 126 is formed between the turning connection point 123 and its adjacent edge point 124.

[0028] It should be noted that on the first center surface, there are two transition arcs 126, located on both sides of the arched arc 125.

[0029] The arched arc 125 facilitates the arching of the first structural part 110 and / or the second structural part 120 in a direction away from each other, thereby forming a sealed cavity 130. The transition arc 126 enables the sealed cavity 130 to be sealed and connected, while also increasing the distance between the edge part 122 and the water surface. This allows for the adsorption of evaporated water vapor and also enables adjacent floats 100 to overlap or disperse, providing an adjustment range for the distance between adjacent floats 100. This makes the coverage area of ​​adjacent floats 100 adjustable, improving the adaptability of the floats 100.

[0030] In addition, when both the first structural part 110 and the second structural part 120 include a main body part 121 and an edge part 122, or when neither the first structural part 110 nor the second structural part 120 includes a main body part 121 and an edge part 122, the first structural part 110 and the second structural part 120 are symmetrical with respect to the horizontal center plane of the floating dish 100, which facilitates the mass production of the floating dish 100 and helps to reduce production costs.

[0031] When one of the first structural part 110 and the second structural part 120 includes a main body part 121 and an edge part 122, the structural part having the main body part 121 and the edge part 122 is positioned close to the water surface so that the edge part 122 can adsorb water vapor and provide a distance adjustment range.

[0032] For example, if the first structural part 110 includes a main body part 121 and an edge part 122, and the second structural part 120 is an independent arc-shaped structure, then the first structural part 110 is set to be close to the water surface.

[0033] It should be noted that when neither the first structural part 110 nor the second structural part 120 includes the main body part 121 and the edge part 122, that is, when both the first structural part 110 and the second structural part 120 are arc-shaped structures on the first center surface, the floats 100 still have the function of adsorbing water vapor and providing a distance adjustment range between two adjacent floats 100, but the adsorption effect and the adjustment range are not as good as those of floats 100 with the main body part 121 and the edge part 122.

[0034] In some embodiments, the height of the floating dish 100 is 0.5-1 meter, and the diameter of the floating dish 100 is 3-5 meters.

[0035] Specifically, the diameter of the float 100 is between 3 and 5 meters, which facilitates its deployment on the water surface and avoids the problem of excessive spacing between adjacent floats 100. In addition, the height of the float 100 is set at 0.5-1 meter, which is a comprehensive design based on the diameter and buoyancy of the float 100, and is conducive to improving the buoyancy performance and practicality of the float 100.

[0036] It should be noted that if the diameter of the floating disc 100 is too small, it is easy for the floating disc 100 to be lost with the reservoir outlet, and it is difficult to intercept, causing losses and affecting the normal operation of the reservoir.

[0037] In some embodiments, the diameter of the first structural portion 110 and the second structural portion 120 is 3-5 meters, and the diameter of the main body portion 121 is 2.5-4.5 meters.

[0038] Specifically, when one or both of the first structural portion 110 and the second structural portion 120 include a main body portion 121 and an edge portion 122, the diameters of the first structural portion 110 and the second structural portion 120 are the same and are within 3-5 meters. Specifically, for the structural portion including the main body portion 121 and the edge portion 122, the diameter of the corresponding main body portion 121 is 2.5-4.5 meters, and the corresponding diameter of the edge portion 122 is 0.5 meters.

[0039] For example, the first structural part 110 includes a main body part 121 and an edge part 122 connected to each other, and the diameter of the first structural part 110 is 4 meters, then the diameter of the main body part 121 is 3.5 meters, and the diameter of the edge part 122 (i.e., the distance between the outer periphery of the main body part 121 and the outer periphery of the edge part 122) is 0.5 meters.

[0040] In this embodiment, the diameter of the first structural part 110 and the second structural part 120 is the same as the diameter of the float 100, which is 3-5 meters. When at least one of the first structural part 110 and the second structural part 120 includes a connected main body part 121 and an edge part 122, the diameter of the main body part 121 is 2.5-4.5 meters, that is, the diameter of the edge part 122 is determined to be 0.5 meters. This is beneficial for the setting of the edge part 122, and facilitates the natural overlap or non-overlap of the edge parts 122 between two adjacent floats 100 to block the water surface and improve the flexibility and adaptability of the float 100.

[0041] Based on the same inventive concept, this application also provides a floating device 001, such as... Figure 3 As shown, it includes a plurality of floating discs 100 as described above, which are used to be laid on the water surface, and at least some of the floating discs 100 are arranged in contact with each other.

[0042] Specifically, multiple floats 100 are laid together on a water surface to collectively cover the water surface and prevent water evaporation. When the area of ​​the multiple floats 100 laid together on the water surface is larger than the water surface area, some adjacent floats 100 may be stacked one on top of the other, or some floats 100 may not be in contact with the water surface. As the water level rises or falls, the water surface area increases, and multiple floats 100 are all laid on the water surface to cover it. Therefore, the number of floats 100 is not fixed, but is based on the goal of completely covering the water surface.

[0043] In addition, among the multiple floating discs 100, the floating discs 100 located on the water surface and in contact with the water surface work together to block the water surface. Therefore, two adjacent floating discs 100 are in horizontal relative contact or vertical relative contact to achieve connection and jointly block the water surface.

[0044] In this embodiment, the floating device 001 includes multiple floating discs 100, which are laid together on the water surface to block the water surface and prevent water evaporation. This can effectively reduce water evaporation in reservoirs with large fluctuations and frequent changes, reduce reservoir water replenishment, reduce evaporation by 80%, and significantly save water replenishment costs.

[0045] In some embodiments, the edges 122 of two adjacent floating dishes 100 are arranged to contact each other or to make staggered contact. Wherein, the edge portion 122 of the floating plate 100 is the edge portion 122 of the first structural portion 110 and / or the second structural portion 120.

[0046] Specifically, when the first structural part 110 or the second structural part 120 of the float 100 includes a main body part 121 and an edge part 122, the corresponding edge part 122 is the edge part 122 of the float 100. When multiple floats 100 are laid on the water surface, the edge parts 122 of two adjacent floats 100 are arranged opposite each other or in accidental contact to achieve the connection of two adjacent floats 100, so as to jointly shield the water surface, avoid water surface exposure and increase evaporation efficiency, thereby helping to reduce water evaporation, reduce reservoir water replenishment costs, and facilitate the normal operation of the reservoir.

[0047] In some embodiments, the plurality of floating dishes 100 include a first floating dish 100, a second floating dish 100, and a third floating dish 100, wherein the first floating dish 100, the second floating dish 100, and the third floating dish 100 have different diameters.

[0048] Specifically, the floating device 001 includes multiple floats 100 with different diameters, including multiple first floats 100, multiple second floats 100, and multiple third floats 100. The diameters of the first, second, and third floats 100 are different, but they are all located within the diameter range of 3-5 meters. Due to the different diameters, the heights of the first, second, and third floats 100 are also different. The floats 100 at different heights are staggered and contact each other to achieve the enclosure of the water surface to block sunlight. Furthermore, the first, second, and third floats 100 can stack or disperse themselves according to changes in water level and water surface, adapting to frequent changes in water level and water surface in pumped storage reservoirs, which helps to improve the practicality of the floating device 001.

[0049] For example, the diameter of the first floating dish 100 is 3 meters, the diameter of the second floating dish 100 is 4 meters, and the diameter of the third floating dish 100 is 5 meters.

[0050] It should be noted that the ratio of the number of the first floating plate 100, the second floating plate 100 and the third floating plate 100 is 1:1:1.

[0051] Based on the same inventive concept, this application also provides an anti-evaporation system, such as Figure 3 and Figure 4As shown, the system includes a floating device 001 and an intercepting net 200 as described above. The floating device 001 is used to float on the surface of the reservoir water, and the intercepting net 200 is used to be located at the outlet of the reservoir to intercept the floating device 001. The width of the intercepting net 200 is adapted to the outlet, and the height of the intercepting net 200 is higher than the height of the outlet.

[0052] Specifically, the anti-evaporation system includes the floating device 001 and the intercepting net 200. The floating device 001 is used to float on the water surface of the reservoir to block the water surface. The intercepting net 200 is located at the outlet of the reservoir to intercept the floating device 001 when the reservoir discharges water, so as to prevent the floating device 001 from flowing out with the water through the outlet and affecting the normal power generation of the corresponding hydropower station.

[0053] It should be noted that, in order to ensure the interception effect of the interception net 200, the width of the interception net 200 is set to match the width of the water outlet, and the height is higher than the height of the water outlet, so that when the water in the reservoir reaches the highest water level, the floating device 001 is prevented from being higher than the interception net 200, thus preventing the floating device 001 from being intercepted by the interception net 200.

[0054] The bottom of the interception net 200 is 0-0.5 meters away from the bottom surface of the outlet, which is less than the height of the float 100, thus enabling it to intercept the float 100 in the floating device 001.

[0055] In addition, the mesh size of the interception net 200 is no larger than 0.5 meters, which can not only not affect the flow of water, but also effectively intercept the floating disc 100.

[0056] In this embodiment, the floating device 001 is laid on the surface of the reservoir to reduce water evaporation. The intercepting net 200 is set at the reservoir outlet to prevent the float 100 of the floating device 001 from reaching the outlet and entering the waterway to affect the operation of the corresponding generator set equipment in the reservoir. The technology is simple and feasible, requires little investment, and has obvious effects. The floating device 001 adapts to the normal operation of the reservoir and can also reduce water evaporation, thus realizing the sustainable and healthy operation of the reservoir.

[0057] In some embodiments, at least one first connector 300 is provided on each of the two sides of the water outlet, and at least one second connector 400 is provided on the bottom surface of the water outlet. The two sides of the intercepting net 200 are respectively connected to the first connectors 300 on the two sides of the water outlet, and the bottom surface of the intercepting net 200 is connected to the second connector 400.

[0058] Specifically, both the first connector 300 and the second connector 400 are pre-embedded parts, that is, they are pre-embedded when the water outlet is repaired. This setting can improve the connection strength between the first connector 300 and the second connector 400 and the water outlet, and prevent the interception net 200 from detaching from the water outlet during use due to the low connection strength between the first connector 300 and the second connector 400 and the water outlet.

[0059] At least one first connector 300 is provided on one side of the water outlet, and the first connector 300 is provided opposite to it on the other side. That is, the first connectors 300 provided on both sides of the water outlet are symmetrically arranged to ensure that the connection strength on both sides of the interception net 200 is the same.

[0060] At least one second connector 400 is provided on the bottom surface of the outlet so that the bottom surface of the interception net 200 is connected to the outlet through the second connector 400. Since the second connector 400 is lower than the first connector 300, the second connector 400 is subjected to a larger force when the outlet drains water. Therefore, the second connector 400 is different from the first connector 300 to ensure the stability of the interception net 200.

[0061] For example, the first connector 300 is a connecting ring, and the side of the intercepting net 200 passes through the connecting ring to connect with the first connector 300.

[0062] In this embodiment, the first connector 300 is disposed on the side of the water outlet, and the second connector 400 is disposed on the bottom surface of the water outlet. The first connector 300 is used to connect to the side of the interception net 200, and the second connector 400 is used to connect to the bottom surface of the interception net 200. The arrangement of the first connector 300 and the second connector 400 ensures a stable connection between the interception net 200 and the water outlet, which is beneficial to the stability and service life of the anti-evaporation system.

[0063] In some embodiments, the anti-evaporation system further includes at least one support rod 500, which is connected to the interception net 200, and the bottom end of the support rod 500 is connected to the second connector 400.

[0064] Specifically, the support rod 500 and the second connector 400 are arranged in a one-to-one correspondence. The bottom end of the support rod 500 is connected to the second connector 400, the top end of the support rod 500 is a free end, the body of the support rod 500 is connected to the interception net 200, and the interception net 200 is connected to the second connector 400 through the support rod 500.

[0065] It should be noted that the number of the support rods 500 and the second connectors 400 is related to the width of the water outlet, so as to ensure the stability of the width setting of the interception net 200.

[0066] The number of the first connectors 300 is also related to the height of the interception net 200, so as to ensure the stability of the interception net 200 in the height direction.

[0067] For example, the second connector 400 is a base with a threaded groove, the bottom periphery of the support rod 500 is threaded to fit the threaded groove, and the support rod 500 is threadedly connected to the second connector 400.

[0068] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this application (including the claims) is limited to these examples; within the scope of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0069] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
