Description

Technical Field

[0001] The present invention relates to the technical field of flood walls, and in particular to an adaptive lifting flood wall system and a control method. Background Art

[0002] Floods and storm surges have long been one of the main factors threatening the development of the national economy and society. Regional flood control standards are gradually improving, and important cities are increasingly unable to afford or be flooded. Correspondingly, on the one hand, flood control capabilities and standards still need to be improved, but urban areas, especially core areas, have been exhausted, and it is impossible to continue to raise and thicken levees; on the other hand, due to the frequent occurrence of local short-duration heavy rainfall, the flood control situation under extreme climates has become increasingly severe. At present, flood control, especially urban flood control, mainly relies on levee projects, that is, by raising or thickening levees to make their top elevations higher than the design flood level of the corresponding frequency, so as to confine floods within the river channel. However, raising, thickening, and reconstructing levees often results in additional construction land that is difficult to solve; on the other hand, simply raising levees to defend against small-scale floods (tides) is not entirely desirable, as it affects the people's need for water in the long term; and the use of temporary flood control baffles is not only time-consuming and labor-intensive, but also difficult to respond quickly to emergencies.

[0044] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0045] like Figure 1 As shown, a first aspect of the present invention provides an adaptive lifting flood wall system, comprising a multi-stage lifting device 1, a fixing device 2, a connecting water-stopping device 3 and a floating device 4.

[0046] like Figure 1 , 2As shown in Figures 3 and 4, the multi-stage lifting device 1 includes a first-stage lifting device 11, a second-stage lifting device 12, and a third-stage lifting device 13; the first-stage lifting device 11 includes a plate body 11a, an upper non-return device 11b, a first exhaust valve 11c, and a lower non-return device 11d, and the first-stage lifting device 11, the second-stage lifting device 12, and the third-stage lifting device 13 have the same structure, the upper non-return device 11b is located on the upper outer side of the plate body 11a, the first exhaust valve 11c is located on the top of the upper non-return device 11b, the lower non-return device 11d is located on the inner side of the plate body 11a, the lower non-return device 11d on the first-stage lifting device 11 is in contact with the fixing device 2, and the first-stage lifting device 11, the second-stage lifting device 12, and the third-stage lifting device 13 are installed adjacently and in parallel.

[0047] like Figure 1 , 3 As shown, water-stop slide strips 11e are arranged on both sides of the board body 11a on the first-stage lifting device 11, the second-stage lifting device 12 and the third-stage lifting device 13. The water-stop slide strips 11e include water-stop strips and sliders, and the board body 11a can be arranged to be S-shaped.

[0048] It should be noted that, while the multi-stage lifting device 1 can rise by its own buoyancy, it can also be driven to rise by the floating device 4, which is made of lightweight materials; when the water level of the external river is lower than the bottom of the multi-stage lifting device 1, the top of the multi-stage lifting device 1 and the top of the fixing device 2 remain in a horizontal state; when the water level of the external river rises above the bottom of the multi-stage lifting device 1, the multi-stage lifting device 1 begins to be affected by buoyancy, and as the water level rises to a certain height, the multi-stage lifting device 1 causes the first-stage lifting device 11, the second-stage lifting device 12 and the third-stage lifting device 13 to begin to rise synchronously as a whole under the action of buoyancy; when the water level of the external river rises further, the board body 11a of the first-stage lifting device 11 rises completely, and at this time the lower part of the board body 11a is set at the bottom The non-return device 11d and the non-return structure 22 on the fixing device 2 are in contact and restrain each other, so that the first-stage lifting device 11 no longer continues to rise and together with the fixed structure 21 forms a closed first-stage flood control system, thereby achieving a flood control effect of a certain height of the outer river water level and improving the flood prevention capacity; at the same time, the water-stop slide can resist the entry of floods and restrict the sliding of the multi-stage lifting device, thereby improving the operation safety and service life of the flood wall. The first exhaust valve 11c can discharge internal gas when the first-stage lifting device 11 rises, thereby preventing the internal gas resistance from causing the first-stage lifting device 11 to be unable to rise, thereby ensuring the stable operation of the flood wall. The board body is set to be S-shaped, which can greatly improve the flood control strength of the multi-stage lifting device, ensuring that the board body is not damaged under the impact of high-intensity floods and is strong and reliable.

[0049] like Figure 1 , 4As shown, the upper non-return device 11b of the first-stage lifting device 11 is in contact with the plate body 11a of the second-stage lifting device 12, and the upper non-return device 11b of the first-stage lifting device 11 can slide closely on the plate body 11a of the second-stage lifting device 12, and is in contact with and tightly connected with the lower non-return device 11d of the second-stage lifting device 12 to form a water-stop structure.

[0050] It should be noted that when the first-level lifting device 11 cannot continue to rise, when the water level of the outer river rises further, the board 11a of the second-level lifting device 12 will rise completely. At this time, the lower check device 11d set at the bottom of the board 11a of the second-level lifting device 12 and the upper check device 11b set at the first-level lifting device 11 will contact and restrict each other, so that the second-level lifting device 12 will no longer continue to rise and will form a closed second-level flood control system together with the first-level lifting device 11, thereby achieving a higher level of flood control effect at the outer river water level, so that the second-level flood control system can withstand medium and high-intensity floods and improve the flood prevention capacity of the flood wall system.

[0051] like Figure 1 , 4 As shown, the upper non-return device 11b of the secondary lifting device 12 is in contact with the plate body 11a of the tertiary lifting device 13, and the upper non-return device 11b of the secondary lifting device 12 can slide closely on the plate body 11a of the tertiary lifting device 13, and is in contact with and tightly connected with the lower non-return device 11d of the tertiary lifting device 13 to form a water-stop structure.

[0052] It should be noted that when the secondary lifting device 12 cannot continue to rise, when the water level of the outer river rises further, the board 11a of the tertiary lifting device 13 will rise completely. At this time, the lower check device 11d set at the bottom of the board 11a of the tertiary lifting device 13 and the upper check device 11b set at the secondary lifting device 12 will contact and restrict each other, so that the tertiary lifting device 13 will no longer continue to rise and will form a closed three-level flood control system together with the secondary lifting device 12, thereby achieving a higher level of flood control effect at the outer river water level, so that the secondary flood control system can withstand high or extremely high intensity floods and improve the flood prevention capacity of the flood wall system.

[0053] like Figure 1 , 2 As shown, the fixing device 2 includes a fixing structure 21 , a check structure 22 and a second exhaust valve 23 . The check structure 22 is located at the upper end of the fixing structure 21 , and the second exhaust valve 23 is located at the top of the check structure 22 .

[0054] It should be noted that the fixing device 2 includes but is not limited to facilities such as embankments, flood walls, and wave-breaking walls. The fixing device 2 is mainly used as a carrier to install and fix the multi-stage lifting device 1 and the connecting water-stop device 3, so that the multi-stage lifting device 1 can have an operating basis to form a solid flood wall system, and the connecting water-stop device 3 can also stably drive the multi-stage lifting device 1 to operate efficiently, preventing high and low intensity floods from invading the embankment and threatening the lives of shore workers and residents, and providing a safe foundation for the flood wall system to exert its overall performance.

[0055] like Figure 1 , 5 As shown, the connecting water-stop device 3 includes a primary water-stop groove 31, a secondary water-stop groove 32, and a tertiary water-stop groove 33. The primary water-stop groove 31, the secondary water-stop groove 32, and the tertiary water-stop groove 33 are installed on both sides of the outside of the connecting water-stop device 3. An inner groove 34 is provided inside the connecting water-stop device 3. A sliding rod 37 is installed in the inner groove 34. The sliding rod 37 includes a rod body 37a. Slide blocks 37b are provided on both sides of the rod body 37a, and the slide blocks 37b are in contact with the inner groove 34.

[0056] like Figure 1 , 5 As shown in Figures 6 and 8, one end of two first ropes 35 are connected to the sliding rod 37, and the other ends of the two first ropes 35 are synchronously connected to the top of the three-stage lifting device 13 along the three-stage water-stop slide groove 33. Each of the first ropes 35 passes around the first fixed pulley 36. The first fixed pulley 36 is provided with two groups and is symmetrically installed. The first fixed pulley 36 includes a first fixed shaft 36a, which is installed on the top of the connecting water-stop device 3, and the first pulley 36b is installed on the first fixed shaft 36a.

[0057] like Figure 1 , 6 As shown in Figures 7, 8 and 9, one end of a second rope 39 is also connected to the sliding rod 37, and the other end of the second rope 39 is fixed to the floating device 4. The floating device 4 is placed on the supporting device 310, and the supporting device 310 is welded to the outer side of the connecting water-stopping device 3. The second rope 39 passes around the second fixed pulley 38, and the second fixed pulley 38 includes a second fixed shaft 38a, which is installed at the bottom of the connecting water-stopping device 3, and a second pulley 38b is arranged on the second fixed shaft 38a.

[0058] like Figure 1 , 5As shown, the water-stop slides 11e on both sides of the first-level lifting device 11, the second-level lifting device 12 and the third-level lifting device 13 slide in the first-level water-stop slide groove 31, the second-level water-stop slide groove 32 and the third-level water-stop slide groove 33 respectively; the slide groove heights of the first-level water-stop slide groove 31, the second-level water-stop slide groove 32 and the third-level water-stop slide groove 33 correspond one by one to the first-level lifting device 11, the second-level lifting device 12 and the third-level lifting device 13 respectively and increase sequentially.

[0059] It should be noted that when the multi-stage lifting device 1 cannot rise by its own buoyancy, the floating device 4 and the pulley system can be used to drive the multi-stage lifting device 1 to rise; when the water level of the external river is lower than the bottom of the floating device 4, the multi-stage lifting device 1 and the floating device 4 are not affected by buoyancy, and the flood wall system does not operate; when the water level of the external river rises above the bottom of the multi-stage lifting device 1, the multi-stage lifting device 1 and the floating device 4 begin to be affected by buoyancy, and when the water level rises to a certain height, the floating device 4 floats upward, and at this time the floating device 4 pulls the second rope 39, and due to the arrangement of the second fixed pulley 38, when the floating device 4 floats upward, the second rope 39 is pulled upward. 9 will synchronously pull the slide rod 37 downward, so that the slide rod 37 slides horizontally downward in the inner slide groove 34. When the slide rod 37 slides downward, due to the setting of the two groups of first fixed pulleys 36, the slide rod 37 moves on the two groups of first fixed pulleys 36 respectively through the two first ropes 35, thereby pulling the three-stage lifting device 13 to move horizontally upward, and the three-stage lifting device 13 begins to rise, completing the process of the floating device 4 driving the multi-stage lifting device 1 to operate by itself, and together with the fixing device 2 and the connecting water-stopping device 3, a closed flood prevention system is formed, realizing the automatic flood prevention adjustment and control of the flood wall system, improving the regional flood prevention water level and flood prevention capacity, and enhancing the flood prevention capacity.

[0060] It should be noted that when the water level of the outer river rises further, the floating device 4 continues to drive the three-stage lifting device 13 to rise. When the three-stage lifting device 13 rises to the maximum limit, the three-stage lifting device 13 begins to couple with the upper check device 11b of the secondary lifting device 12 through the lower check device 11d, and begins to drive the secondary lifting device 12 to rise through the lower check device 11d, until the three-stage lifting device 13 moves to the top of the three-stage water-stopping chute 33, so as to achieve the purpose of step-by-step rising of the multi-stage lifting device 1, and realize the effect of controlling the height level of the multi-stage lifting device 1 by the height of the outer river water level, so as to confine the river water in the river channel; when the water level drops, the floating device 4 drops accordingly, and the multi-stage lifting device 1 also drops step by step and returns to its initial state. The step-by-step adjustment capability of the flood wall system improves the flexible switching of flood control levels, effectively improves flood control adaptability, reduces the damage and losses caused by flood disasters, and ensures the safety factor of flood defense.

[0061] A second aspect of the present invention provides a control method for an adaptive lifting flood wall system, which is applied to any one of the adaptive lifting flood wall systems described above, and comprises the following steps:

[0062] Acquire several historical height values ​​of the multi-stage lifting device within a preset time period, and divide the preset time period into even time periods to obtain several time nodes;

[0063] Constructing a change curve graph, importing the several historical height values ​​and the several time nodes into the change curve graph, and obtaining a height value-time change curve graph;

[0064] Extracting an altitude value-time change curve from the altitude value-time change curve diagram, and calculating the altitude value-time change curve based on a difference method to obtain a curvature of the altitude value-time change curve;

[0065] Determine whether the curvature of the height value-time variation curve is greater than a preset curvature, and if so, calculate the difference between the curvature of the height value-time variation curve and the preset curvature to obtain a curvature deviation threshold, and adjust the weight or quantity of the floating device based on the curvature deviation threshold;

[0066] If it is less than, the abnormal operation of the multi-stage lifting device is analyzed to generate a fault result.

[0067] It should be noted that the operation of the multi-stage lifting device is mainly regulated by the buoyancy exerted by the external river water on the floating device. However, if the weight of the floating device is greater than the buoyancy exerted by the external river water, the buoyancy of the external river water will not be able to drive the floating device to float upward, so that the multi-stage lifting device cannot rise, and the external river water overflows into the embankment; therefore, a preset time period can be selected as a test node. During this preset time period, the rising height of the multi-stage lifting device changes multiple times. Therefore, the preset time period can be evenly divided into several time nodes and the rising height values ​​of the multi-stage lifting device corresponding to the time nodes are obtained for further analysis. By constructing a height value-time change curve graph through the change curve graph, the degree of change of the height value can be more accurately and intuitively analyzed, and the data error can be reduced. The height value-time change curve graph reflects the change of the height value of the multi-stage lifting device over time nodes. Therefore, by calculating and analyzing the curvature, it can be determined whether the buoyancy exerted by the external river water can drive the multi-stage lifting device to do an upward movement, and adjust the weight and quantity of the floating device according to the judgment result, or detect the multi-stage lifting device. The present invention can analyze whether the buoyancy of the external river water can drive the operation of the multi-stage lifting device, and make corresponding adjustments and optimizations, thereby improving the efficiency and stability of the flood wall system operation, reducing the occurrence of operating errors, and thereby improving the flood control and waterlogging prevention capabilities with high reliability.

[0068] Further, in a preferred embodiment of the present invention, if the value is less than , the abnormal operation of the multi-stage lifting device is analyzed to generate a fault result, which specifically includes the following steps:

[0069] Analyze the altitude value-time change curve to obtain the highest point of historical altitude values ​​and the lowest point of historical altitude values;

[0070] Obtaining the highest value time node and the lowest value time node according to the highest point and the lowest point in the height value-time change curve diagram, and calculating the difference between the highest value and the lowest value to obtain the actual height change difference;

[0073] It is determined whether the actual height change difference is greater than the height change prediction value. If so, there is a deviation in the operation of the multi-stage lifting device, and the multi-stage lifting device is marked as an abnormal fault, generating a fault result.

[0074] It should be noted that the structure of the multi-stage lifting device is compact, and the connection and driving methods are relatively simple. However, due to the changeable environment of the outer river bank, after a period of use, the water-stop slide, the upper non-return device, the lower non-return device and other places are prone to wear, aging, breakage and other faults, which greatly reduces the operation quality of the multi-stage lifting device, resulting in the inability to perform the rising action in time when floods occur; by selecting the highest point and the lowest point of the change value and the time period between the two as the analysis object in the height value-time change curve diagram, analyzing the actual height change difference between the two points, and predicting the height change value in the time period, obtaining the height change prediction value, and comparing the difference between the height change prediction value and the actual height change value, it can be known whether the multi-stage lifting device has an operation abnormality, and if so, it is marked as a fault. The present invention can detect and judge the operation faults of the multi-stage lifting device, can timely discover faults and perform maintenance, reduce the flood control errors caused by faults, reduce the impact of floods on the lives of the masses, and improve the operation quality and efficiency of the multi-stage lifting device.

[0075] The above is based on the ideal embodiment of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
