The invention is related to a technology for providing resilience to flood, more particularly to a triadic recurve implosion flood navigation for in-situ tailoring yearn system - [TRINITY - D20].
Seasonal hurricanes, or more frequent extreme climate, often bring excess precipitation, which, if not drained in time, can accumulate and converge into a flood over time. In the construction and layout of city, there is usually not much reserved space for the free flow or circulation of catastrophic heavy rain or flood, which makes it more difficult to effectively drain a sudden flood.
Moreover, if the city is located in the coastal area, melting of icebergs due to global warming will raise sea levels, which may lead to flooding in low-lying areas of the city, severe erosion of beaches and sea cliffs, and intrusion of sea salt into aquifers.
In addition, flood can carry plastic waste and even highly polluting or dangerous chemical products into the sea, causing rapid algae growth, ocean pollution and acidification. And, flood will also take away a large amount of soil on the earth’s surface, making the land barren, destroying vegetation, and deteriorating ecology, which will eventually lead to severe desertification.
It is particularly pointed out that since Saint Christopher and Nevis is located in the Caribbean Sea, based on its geographical location and hydrological characteristics, it is necessary to deal with the above-mentioned problems with corresponding measures, providing regular and sustained water resources management strategies will help fundamentally mitigate or reduce the occurrence of disasters.
In addition, with the development of social economy and the increase of human development and engineering activities, the natural ecological environment and biodiversity have been changed, especially the replenishment rate of groundwater has dropped significantly, and groundwater resources are also over-exploited and polluted, resulting in rapid decreasing of available groundwater.

Wherein, identification of biological functions and bionic design and development of biological structures for the tailoring mechanism 10 was first carried out and completed independently by Professor CHIU Kuo-Wei from the Department of Architecture of Tunghai University, and then was delivered to graduate students to instruct them to carry out the structural design test and functional design confirmation of the triadic recurve in-situ flood navigation array of model TRINITY - D20™. In particular, the design idea of the tailoring mechanism 10 of the invention is derived from guard cells with elastic inner walls of different thicknesses at different positions expanding unevenly due to the presence of air, and forming an osmotic pressure (vapor pressure difference) between the two for gas exchange.
Specifically, the tailoring mechanism 10 comprises a first unit 11 and a second unit 14, wherein the first unit 11 has an arc-shaped first arcuate portion 12, and two arcuate ends of the first arcuate portion 12 are respectively defined as a first end 121 and a second end 122. In this embodiment, the first arcuate portion 12 has a plurality of first columns 13, and the first columns 13 are spaced apart from one another and arranged in an arcuate shape of the first arcuate portion 12.
The second unit 14 has an arc-shaped second arcuate portion 15, and two arcuate ends of the second arcuate portion 15 are respectively defined as a first end 151 and a second end 152. In this embodiment, the second arcuate portion 15 has a plurality of second columns 16, and the second columns 16 are spaced apart from one another and arranged in an arcuate shape of the second arcuate portion 15.
Wherein, each of the first columns 13 and each of the second columns 16 are respectively quadrilateral in cross-sectional shape in a radial direction, preferably trapezoidal. In addition, length, width, height, structural shape, quantity, and positional relationship of the columns can be set according to a size of a field disposed with the tailoring mechanism 10 or a predicted flood water level. For example, as shown in
In addition, since the columns comprised in each of the arcuate portions are spaced apart from one another, each of the arcuate portions has a plurality of gaps, when the fluid flows through each of the arcuate portions, the fluid can be vented out through the gaps to facilitate evacuation of the fluid.
Further, a large number of hydrophilous plants can further be planted on a land disposed with the tailoring mechanism 10. In addition to increasing a moisture content of the soil, the plants can also be used to provide shade from the sun so that the soil can be maintained at an appropriate temperature to reduce evapotranspiration in the soil.
Furthermore, in other embodiments, the tailoring mechanism 10 can be disposed in an intertidal zone or a neritic zone to divide the waters into a plurality of blocks, which can not only slow down coastal erosion, but also create habitats for fish or marine life.
In addition, curvature, arc length, thickness and shape of the first arcuate portion 12 and the second arcuate portion 15 can be adjusted according to actual needs, such as the first arcuate portion 12 and the second arcuate portion 15 in this embodiment are respectively C-shaped, and in other embodying modes, the first arcuate portion 12 or the second arcuate portion 15 can be shaped with a thick middle part, and two gradually thinned sides extending from the middle part.
As shown in
Wherein, ratio or size relationship between the first distance D1, the second distance D2 and the holdup distance D5 can be adjusted according to actual needs, sizes of the distances can respectively determine widths of parts of the curved channel 17 corresponding to the distances. In particular, the second distance D2 can define a width of the inflow end 171 to determine an inflow flow rate. The holdup distance D5 can define a size of a holdup area in the curved channel 17 formed by the arcuate portions intersecting with each other to determine a vortex size formed by an external fluid flowing through the holdup area.
In addition, on the premise that curvature and size of each of the arcuate portions are the same, if a width of the inflow end 171 is equal to a width of the outflow end 172, the tailoring mechanism 10 can be defined as a symmetrical structure.
According to calculation and simulation results, the first distance D1 is between 0.1 m and 0.5 m, and the second distance D2 is 0.5 m.
With the composition of the above components, the main implementation steps of the first embodiment of the invention are as follows:
Firstly, an external fluid enters the curved channel 17 through the inflow end 171. At this time, a fluid pressure is high and its flow rate is relatively high. When there is another static fluid remaining in the curved channel 17, the external fluid will converge with the static fluid and flow together toward an interior of the curved channel 17. In this embodiment, the external fluid is a liquid mainly composed of water.
Then, when the external fluid flows through a connecting position between the first arcuate portion 12 and the second arcuate portion 15, since a bending direction of the concave arcuate surface of the second arcuate portion 15 is opposite to a bending direction of the concave arcuate surface of the first arcuate portion 12, a pressure generated by the external fluid concentrating on the connecting position will cause an implosion, and a large proportion of the external fluid will be vented out through the gaps between the columns, and the pressure will drop sharply.
Finally, the remaining external fluid flows along the curvature of the second arcuate portion 15, and its flow velocity gradually becomes slower, and slowly and calmly flows out to a designated area from the outflow end 172, or the remaining external fluid remains statically in the curved channel 17.
Please refer to a second embodiment of the invention shown in
In addition, a minimum distance between the two adjacent second ends 152A of the second arcuate portions 15A of the tailoring mechanisms 10A is a third distance D3, preferably, the third distance D3 is 0.5 m, so that there is an appropriate buffer space between the tailoring mechanisms 10A to achieve a better flow effect.
As shown in
Specifically, between any two of the adjacent tailoring mechanisms 10B, one end of the second arcuate portion 15B of the tailoring mechanism 10B preceding sequentially located at another end (i.e., the second end 152B) of an arcuate shape of the outflow end 172B is located in the curved channel 17B of the subsequent tailoring mechanism 10B, and one end of the first arcuate portion 12B of the subsequent tailoring mechanism 10B located at another end (i.e., the first end 121B) of an arcuate shape of the inflow end 171B is located in the curved channel 17B of the tailoring mechanism 10B preceding sequentially, and the curved channel 17B of the tailoring mechanism 10B preceding sequentially and the curved channel 17B of the subsequent tailoring mechanism 10B are partially overlapped and communicated with each other. Accordingly, the external fluid can be caused to flow in the curved channels 17B of the tailoring mechanisms 10B that are arranged one by one in order to gradually slow down its flow rate.
As shown in
In addition, the invention can also be used in conjunction with another water conservancy facility to be capable of managing water resources or utilizing water conservancy under different climatic conditions or states. Wherein the water conservancy facility can be, but is not limited to, a rainwater collecting mechanism 30, a bridge water storage mechanism 40 or a road space tailoring mechanism 50, and the structural features of these mechanisms are described in detail below.
As shown in
Specifically, the collecting part 32 has a plurality of arcuate plates 311, each of the plates 311 is a modular nesting component, which can be assembled and combined with one another arbitrarily. For example, any two of the plates 311 are assembled with each other with convex arcuate surfaces facing outward (as shown in
Furthermore, the collecting part 32 and the water storage part 33 are connected with each other through a plurality of pipelines 34, so that the rainwater collected by the collecting part 32 can be distributed and stored in the water storage part 33 through the pipelines 34.
The water storage part 33 has a tank 331, inside the tank 331 is divided into a plurality of storage spaces 333 communicating with one another by a plurality of partitions 332, and the storage spaces 333 are arranged in the tank 331 in sequence from the outside to the inside. The storage spaces 333 receive the rainwater collected by the collecting part 32 through the pipelines 34 respectively, and the storage space 333 located at the outermost periphery receives the rainwater first, when that storage space 333 is full, the rainwater will overflow to the next storage space 333. Accordingly, the rainwater collecting mechanism 30 can be used as a water storage facility to improve the problem of water resources shortage.
In addition, the water storage part 33 is further connected with a drain pipe 35, when the storage spaces 333 are filled with the rainwater to the fullest, or when a water level is about to be full, the drain pipe 35 can be used to drain excess rainwater.
In particular, the design idea of the rainwater collecting mechanism 30 is derived from the shape of the leaves of pineapple.
As shown in
The partition part 42 has a plurality of first partitions 421 and a plurality of second partitions 422, wherein each of the first partitions 421 is respectively disposed in the column body 41 to divide the inner space 411 along a cross-section of the column body 41 in an axial direction into two outer ring areas 412, a connecting area 413 and two central areas 414. Each of the outer ring areas 412 is located at a position adjacent to peripheral walls on two sides of the column body 41, the connecting area 413 is spanned inside the column body 41, two ends thereof are respectively connected to each of the outer ring areas 412, and the connecting area 413 is located between the two central areas 414.
Furthermore, the second partitions 422 are separately disposed in each of the central areas 414, so that each of the central areas 414 is separated by a plurality of pipes 415 that communicate with one another and are parallel to one another. Wherein each of the pipes 415 can be designed with different widths and lengths.
Accordingly, as shown in
Finally, when one set of the bridge water storage mechanisms 40 is full of water, the water can flow into the other set of the bridge water storage mechanism 40 to accumulate and store more water resources.
In particular, the design idea of the bridge water storage mechanism 40 is derived from the xylem used to transport water in trees, wherein, when the tree is upright and functioning normally, the xylem is used to transport nutrients and water absorbed by the roots; however, when the tree is brought down and laid on its side, excess water is trapped in the trunk and builds up gradually.
As shown in
When a tide or a flood exceeds a predetermined capacity, the road module 52 will be dismantled, so that the plates 53 are positioned in the unfolded position to provide more space for a water body to flow under the road module 52; after the tide or the flood has withdrawn, the plates 53 will be reassembled to position in the storage position.
In particular, the design idea of the road space tailoring mechanism 50 is derived from the principle of water regulation at the roots of trees during the dry season and the wet season.
