Description

Technical Field

[0001] The invention relates to the technical field of fresh water storage, and in particular to a ceiling-type flexible water storage structure suitable for underwater use. Background Art

[0002] As an emerging water resource management strategy, underwater water storage technology has shown great development potential. Compared with traditional groundwater storage and reservoir storage, underwater water storage has unique advantages and characteristics: in terms of space utilization, underwater water storage does not occupy precious land space and can be laid out in a wide area of ​​the seabed, which is especially suitable for islands and coastal areas where land resources are scarce. Although groundwater storage does not occupy surface space, it is restricted by geological conditions and may affect the groundwater hydrological environment. Reservoir storage also requires large tracts of land for construction, which has a great impact on the ecological environment and surface land use. In terms of environmental adaptability, underwater water storage is deep in the seabed, unaffected by weather changes and surface activities, and has high stability. Groundwater storage may be affected by geological activities, such as earthquakes and groundwater level changes. Reservoir storage is susceptible to climate change, such as droughts and floods, and has a large amount of evaporation. In terms of safety, underwater water storage has military and security significance, and seabed water storage bags are more difficult to be discovered and destroyed, providing higher security. Both groundwater storage and reservoir storage may face the risk of contamination and may become targets of attack in extreme situations such as war. In terms of economics, the initial construction cost of underwater water storage may be high, but the long-term operating cost is low, especially in terms of maintenance and protection. Groundwater storage and reservoir storage: may require more frequent maintenance and cleaning, which will increase long-term costs.

[0003] There are many ways to store fresh water on offshore islands, mainly including the following methods:

[0004] 1. Underground freshwater storage: Some islands use underground freshwater lenses for water storage. These freshwater lenses are formed by rainfall infiltrating into the island's underground. Low-permeability media materials can be set up in the outer area of ​​the island to prevent seawater intrusion, thereby significantly increasing the underground freshwater reserves.

[0005] 2. Rainwater collection: The rainwater collection system on the island collects and stores rainwater by building water storage dams or water storage tanks. Some islands also plan to build underground reservoirs on reclaimed land to store the collected rainwater underground for emergency use.

[0006] 3. Desalination: Many islands use desalination technology to convert seawater into fresh water to meet water needs. This method is particularly suitable for small island countries that do not have the geographical conditions for fresh water resources.

[0007] 4. Wedge-shaped wells: In some small island countries in the South Pacific, wedge-shaped wells have become an important way to obtain fresh water from underground freshwater layers. These wells use the density difference between underground freshwater layers and saltwater layers to extract fresh water resources by digging at a specific depth.

[0008] Therefore, in response to the urgent need for storing fresh water on existing offshore islands and reefs, a roof-type flexible water storage structure suitable for offshore islands and reefs is provided, which provides a new technical solution for storing fresh water on offshore islands and reefs.

[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] Please refer to Figure 1 - Figure 5 , a ceiling-type flexible water storage structure suitable for underwater use, comprising:

[0045] A flexible capsule 1, wherein the flexible capsule 1 comprises an inner capsule membrane and an outer capsule membrane;

[0046] A binding strap 2, which is arranged on the outer surface of the flexible bladder bag 1 and is used to fix the position of the flexible bladder bag 1;

[0047] A concrete ceiling 3, which corresponds to the position of the flexible bag 1, and the flexible bag 1 is located on the inner side of the concrete ceiling 3. The concrete ceiling 3 is used to stabilize the position of the flexible bag 1 and also to increase the external protection of the flexible bag 1;

[0048] The anchor cable, specifically, includes a ground anchor 5, which is arranged at the lower part of the concrete ceiling 3, one end of which is fixed to the lower end of the concrete ceiling 3, and is used to connect the concrete ceiling 3 and play a fixing role; the anchor cable also includes a horizontal anchor chain 4, which is arranged between the flexible bag 1 and the inner side of the concrete ceiling 3, one end of the horizontal anchor chain 4 is connected to the strap 2, and the other end of the horizontal anchor chain 4 is connected to the concrete ceiling 3, and is used to cooperate with the strap 2 and the concrete ceiling 3 to simultaneously limit the range of movement of the flexible bag 1; the flexible bag 1 is fixedly arranged in the seawater below the concrete ceiling 3 by the strap 2 and the horizontal anchor chain 4;

[0049] The breakwater 8 is arranged at an offshore position, and the flexible bag 1 is located between the breakwater 8 and the island 14; its main function is to reduce the dynamic water load of the seawater to ensure the safety and stability of the structure; the anchor 5 is arranged on the seabed between the breakwater 8 and the island 14;

[0050] A water outlet 13 is arranged above the flexible bag 1, and a water pipe 6 is arranged on the water outlet 13. The end of the water pipe 6 away from the water outlet 13 is connected to a water supply system 7. The water supply system 7 is located inside the island reef 14, and the top of the water supply system 7 extends to the outside of the surface of the island reef 14. A water inlet 9 and a drainage valve 10 are arranged above the water supply system 7.

[0051] like Figure 3-Figure 5 As shown, the concrete ceiling 3 includes concrete arches, columns and beams to form a mesh structure, multiple concrete arches are evenly distributed, columns are set at the ends of the concrete arches, and multiple concrete arches and columns are connected by beams. The layout density of these components is designed according to the volume of the flexible bag 1 and the buoyancy required for the concrete ceiling 3 in the water. The water pipe 6 can pass through the opening of the concrete ceiling 3 (i.e., the gap between the concrete arches) to connect the water outlet 13 of the flexible bag 1 with the water supply system 7. The arrangement density of the concrete arches and beams must be adjusted according to actual needs: if they are arranged too sparsely, their weight will be less than the buoyancy of the flexible bag 1 and the concrete ceiling 3 in the water, and the buoyancy of the bag cannot be balanced; if they are arranged too densely, too much material will be consumed, and the overweight structure may cause the bottom to sink, resulting in an accident. Therefore, the design of the concrete ceiling 3 should be carried out according to the volume of the flexible bag 1.

[0052] The flexible bladder 1 is connected to the concrete roof 3 at multiple points by means of straps 2 and multiple horizontal anchor chains 4. The concrete roof 3 can be fixed directly to the seabed or fixed to the seabed by means of retractable anchor cables.

[0053] Furthermore, the inner membrane of the bladder is made of a hydrophobic material, the outer membrane of the bladder is made of a corrosion-resistant and puncture-resistant material, the water pipe 6 includes an inner layer and an outer layer, the inner layer is a nitrile water-resistant rubber tube, and the outer layer is made of a corrosion-resistant and puncture-resistant material.

[0054] The material selection of the water pipe 6 is similar to that of the flexible bladder 1. Its tube wall is composed of two layers, the inner and outer layers. The inner layer of the tube has an isolation function, which can effectively prevent water leakage and corrosion, so as to prevent the internal water from leaking and polluting the marine environment or the ion penetration outside the bladder from causing water quality degradation. The outer layer of the tube has a protective effect, and has sufficient strength, toughness and corrosion resistance to protect the inner layer from being damaged under the action of hydraulic pressure and wave pressure. Different from the flexible bladder 1, the material of the water pipe 6 can be selected with less flexibility and higher rigidity. The inner layer of the tube is made of nitrile water-resistant rubber tube, which has excellent water resistance, and the long-term use temperature can reach 120 degrees Celsius. The low temperature performance is also very good, and the glass transition temperature can reach -55 degrees Celsius. With the increase of nitrile content, the ductility and tensile properties of the rubber tube will increase, but the resilience and low temperature resistance will decrease, which does not affect its water resistance. Its water resistance is far better than other types of rubber tubes, such as EPDM rubber tubes and silicone tubes.

[0055] The flexible bladder 1 adopts a double-layer design, consisting of an outer membrane and an inner membrane. The inner membrane has an isolation function, which can effectively prevent water penetration and resist corrosion. Its main purpose is to prevent internal water leakage from polluting the marine environment and to prevent external ion penetration from causing water quality degradation; while the outer membrane plays a protective role and has the necessary strength, toughness and corrosion resistance to ensure that the inner membrane will not be damaged under the action of hydraulic pressure and wave pressure.

[0056] In the embodiment, the inner membrane of the capsule uses a HDPE anti-seepage membrane, which has excellent acid and alkali resistance and corrosion resistance: it can resist corrosion from more than 80 chemical media with strong acids and alkalis. It has an excellent anti-seepage effect, and the water vapor permeability coefficient K value is less than or equal to 1.0×1013g﹒cm / (cm﹒s﹒Pa). It also has good low-temperature resistance, with a cold brittle temperature between -60 and -70 degrees Celsius, and high-temperature resistance, with a melting temperature between 110 and 120 degrees Celsius. The overall cost is low, the anti-corrosion and anti-seepage effects are significant, and no leakage will occur.

[0057] Compared with traditional coastal water storage methods, for example, the construction cost of seawater desalination for water intake usually ranges from several million to several billion yuan, depending on the scale and technology of the desalination plant. The operating cost is about 3.5 to 9 yuan per cubic meter of fresh water, mainly depending on the energy price and desalination technology. For rainwater collection and storage, the construction cost is between several hundred thousand yuan and several million yuan, and the operating cost is mainly for the maintenance and cleaning of the system. For underground fresh water storage, the construction cost is medium, possibly ranging from several million to tens of millions of yuan, and the operating cost is mainly for the monitoring and maintenance of the water source. If the water storage method is to ship fresh water, generally high operating costs need to be borne. For islands far from the mainland, the cost can be as high as several hundred yuan per cubic meter. The solution proposed by the present invention is to arrange flexible bags 1 in the water, use high-strength and corrosion-resistant TPU material as the bag body (the outer membrane of the bag), with a volume of 50 cubic meters and a price of about 10,000 yuan each. By utilizing the underwater space, the cost of land acquisition and water storage site construction is eliminated, thus significantly reducing the device cost.

[0058] The water storage process is as Figure 1 shown. By raising the water injection port 9 of the water delivery system 7 to a certain height and utilizing the water head difference between the water injection port 9 and the flexible bag 1, automatic water injection without power is achieved.

[0059] The drainage process is as Figure 2 shown. By lowering the water injection port 9, due to the density difference between fresh water and seawater, a pressure difference is generated inside and outside the flexible bag 1, causing the water to automatically rise along the water delivery system 7 to the ground of the reef 14 under the action of the external seawater pressure, realizing automatic drainage using hydrostatic pressure, thereby reducing energy consumption.

[0060] In the present invention, the height of the water injection port 9, the position of the drainage valve 10, and the underwater placement depth of the flexible bag 1 are interrelated. According to the principle of hydraulic balance, during the water injection process, it is ensured that the water pressure above is greater than the water pressure below, that is, P fresh water > P seawater; while during the drainage process, it is ensured that the water pressure above is less than the water pressure below, that is, P fresh water < P seawater. In addition to the water pressure difference, the influence of wave loads on the flexible bag 1 in seawater also needs to be considered. According to the linear wave theory, the wave surface elevation at any point p(x,y) in the wave field;

[0061]

[0062] According to the liquid pressure calculation formula and considering the action of wave pressure, there is:

[0063] During water injection:

[0064] During water discharge:

[0065] Among them, h is the velocity potential of the incident wave, pfreshwater is the density of the stored water; pseawater is the local seawater density; g is the local standard gravitational acceleration; H is the vertical distance from the bottom of the flexible bag 1 to the sea level; h1 is the vertical distance from the drain valve 10 to the sea level; h2 is the vertical distance from the drain valve 10 to the water inlet 9; Z is the wave surface elevation; k is a coefficient related to the wave period; R is the polar coordinate radius of the selected point in the wave field.

[0066] It can be seen from these parameters that the greater the difference between the density of the stored water and the density of the seawater, the deeper the position where the flexible bag 1 is fixed in the sea, or the greater the wave pressure, the higher the required water injection height. If the water injection height is not enough, the water pressure will not be able to overcome the seawater pressure and wave pressure, resulting in the inability to carry out the water injection work. However, the height of the water tower cannot be too high, otherwise it will increase the difficulty of transporting water to the water injection port 9, making the work more time-consuming and laborious.

[0067] The embodiments of the present invention are not limited to the above description, and other implementations are also possible. Any technical solution formed by equivalent replacement or equivalent transformation is within the protection scope of the present invention.

Both ends of the protective sheet 15 are fixedly connected to the strap 2.

The submerged anchor beam 16 is buried at the bottom of the seabed, and the stability of the submerged anchor beam 16 can be improved by the stable anchor frame 18. The connection of each column in the concrete ceiling 3 is realized by the connecting seat 17, so as to realize the movement limit of the concrete ceiling 3.
