Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to a levee toughness protection device for preventing ice and flood impacts. Background Art

[0002] In winter at high latitudes or in some areas, the temperature drops below freezing point, and ice crystals formed on the water surface form bank ice at the river bank with slower flow rate. As the temperature continues to remain below freezing point, the bank ice gradually thickens and spreads to form an ice sheet. During the spring melting process, on the one hand, the temperature inside the ice sheet changes, causing the ice to expand, and the frozen connection between the ice sheet and the slope protection is destroyed, resulting in the climbing movement of the ice sheet, and the slope protection and other ancillary structures are damaged. On the other hand, the ice sheet has not fully melted when the flow rate increases significantly, and it breaks and thaws under the action of water flow and wind, causing ice jams or ice dams, thereby leading to ice floods.

[0003] Currently, levees are usually reinforced to improve their impact resistance to cope with ice floods. However, in actual conditions, levees not only resist the impact of ice floods, but are also damaged by the climbing of the ice sheet. At the same time, the occurrence of ice floods is related to the rupture and floating of the ice sheet near the levee.

DETAILED DESCRIPTION

[0044] See also Figure 1-5 In an embodiment of the present invention, a dike resilience protection device for preventing ice and flood impacts includes:

[0045] The embankment body 1 is laid on both sides of the river bank parallel to the flood flow direction;

[0046] The slope protection 2 is laid on the surface of the embankment body 1, and an anti-seepage body 3 for lowering the water level is also provided inside the embankment body 1;

[0047] A wave-breaking wall 4 is provided on top of the embankment body 1;

[0048] The protection components 5 are arranged in multiple groups and fixedly laid on the water side of the embankment body 1 in contact with the slope protection 2;

[0049] The protective plates 6 are arranged in multiple pieces and fixedly mounted on two adjacent protective assemblies 5. Specifically, when facing the impact of ice and flood, the protective plates 6 cooperate with the protective assemblies 5 to improve the overall ability to resist the impact;

[0050] The ice-breaking assembly 7 is arranged between the protective assemblies 5 and passes through the gap between the protective plates 6 toward the river channel. Specifically, the ice-breaking assembly 7 is arranged near the flood level and can effectively break ice blocks when the ice cover climbs or when ice floods impact.

[0051] The barrier cable 8 has one end fixed at the bottom of the protective component 5 and the other end extending through the protective component 5 into the river channel. Specifically, during the formation of the ice sheet, the barrier cable 8 floats on the river surface and then freezes in the ice sheet. When the ice sheet breaks up but has not completely melted, the barrier cable 8 effectively fixes the ice to prevent the ice from drifting away and blocking the river channel, causing ice floods.

[0052] In this embodiment, Figure 2 , the protection component 5 includes:

[0053] The main horizontal frame 51 is laid in close contact with the slope protection 2;

[0054] The lateral frames 52 are fixed to both ends of the main cross frame 51 and are provided with a plurality of support plates. The support plates are used in conjunction with long bolts inserted into the interior of the embankment body 1 to fix the lateral frames 52. Specifically, the lateral frames 52 are arranged from bottom to top along the slope protection 2 and are fixed by multiple groups of bolts that penetrate the slope protection 2 and penetrate into the embankment body 1, thereby ensuring the stability of the main cross frame 51 and the lateral frames 52 on the embankment body 1.

[0055] Buffer components 53, arranged in multiple numbers and disposed on the main cross frame 51;

[0056] A balancing frame 54 is located above the buffer assembly 53, and a connecting column 55 is fixedly connected to the middle of the balancing frame 54;

[0057] The extension plate 56 is provided on one side of the balancing frame 54 and extends outward to contact the ice-breaking assembly 7 .

[0058] As a preferred embodiment, the balance frame 54 is polygonal, and the upper surface of the balance frame 54 is arranged to fit the protective plate 6, and the upper end surface of the connecting column 55 is provided with a threaded hole for fixed connection with the protective plate 6 by bolts, and the lower end surface of the connecting column 55 is connected to the buffer assembly 53. The specific balance frame 54 increases the area of ​​​​supporting the protective plate 6. When the protective plate 6 is impacted, the buffer assembly 53 is squeezed by the connecting column 55 to offset the impact force.

[0059] As a preferred embodiment, the main cross frame 51 is provided with a plurality of slots 1 511 and slots 2 512 . The slots 1 511 are cylindrical, and the slots 2 512 are strip-shaped. The slots 2 512 are provided on both sides of the single slot 1 511 .

[0060] In this embodiment, Figure 3 , the buffer component 53 includes:

[0061] Two transverse sliders 531 are symmetrically arranged, and the transverse sliders 531 are slidably arranged in the second slot 512;

[0062] The buffer spring 532 has two ends fixed on the two symmetrical transverse sliders 531;

[0063] The center column 533 is slidably disposed between the two transverse sliders 531 , and the upper end surface of the center column 533 is connected to the connecting column 55 , and the lower end of the center column 533 can be slidably extended into the inside of the slot 1 511 .

[0064] It needs to be explained that when the protective plate 6 is impacted, the central column 533 will squeeze the transverse slider 531, and the transverse sliders 531 will slide away from each other. At the same time, the buffer spring 532 will be stretched. Specifically, the impact force of the impact on the protective plate 6 will be shared by the buffer spring 532. Multiple buffer springs 532 can share the objective impact force, thereby improving the ability of the protective plate 6 and the embankment body 1 and the slope protection 2 to withstand the impact of ice and floods.

[0065] As a preferred embodiment, wedge-shaped grooves are provided on the opposing surfaces of the two transverse sliders 531, and matching wedge-shaped protrusions are provided on the surface of the central column 533. In addition, an external heating device can be connected to the interior of the transverse slider 531. Specifically, when an ice sheet is climbing, or when there are ice blocks between the protective plate 6 and the protective component 5 and facing ice floods, only heating the transverse slider 531 can ensure the normal operation of the buffer component 53, that is, ensure that the buffer spring 532 normally shares the impact force, and the overall heating workload is smaller. In addition, the protective plate 6 will squeeze the ice blocks between the protective component 5, and the crushed ice blocks will be carried away by the lower river, ensuring the normal operation of the protective component 5.

[0066] In this embodiment, Figure 4 , the ice-breaking assembly 7 includes:

[0067] A fixing block 71 is fixedly mounted on the main cross frame 51;

[0068] An adjusting rod 72 is slidably disposed inside the fixing block 71 . A limit nut 721 is fixedly disposed on the adjusting rod 72 , and an upper end surface of the adjusting rod 72 contacts the extension plate 56 . Specifically, when the protective plate 6 is impacted, the adjusting rod 72 is squeezed by the extension plate 56 , causing the adjusting rod 72 to slide.

[0069] A support block 73 is fixedly mounted on the protective plate 6;

[0070] The ice-breaking arm 74 is hingedly provided on the fixing block 71 , and a deflection cam 741 is provided at one end of the ice-breaking arm 74 , and an ice-breaking blade 742 is provided at the other end.

[0071] As a preferred embodiment, a compression spring is sleeved on the adjusting rod 72, and both ends of the compression spring are respectively limited by the lower end surface of the limiting nut 721 and the upper end surface of the fixing block 71. A pressure plate is provided on the limiting nut 721, and the pressure plate contacts the deflection cam 741, and the support block 73 supports the deflection of the ice-breaking arm 74.

[0072] It needs to be explained that when the adjusting rod 72 slides and squeezes the compression spring, the pressure plate squeezes the deflection cam 741, the ice-breaking arm 74 deflects as a whole, and the ice-breaking blade 742 deflects out from the gap of the protective plate 6, squeezing the ice cubes attached to the protective plate 6, so that the large volume of ice cubes are split, which accelerates the melting of the ice cubes on the one hand and reduces the impact force on the other hand.

[0073] In this embodiment, Figure 5 The barrier rope 8 includes a sleeve 81 provided with a card interface 82, and a plurality of belly bags 83 are provided inside the sleeve 81 with the card interface 82 as the dividing line. The specific card interface 82 ensures the stability of the barrier rope 8 frozen together with the ice cover. The belly bags 83 can be filled with gas so that the barrier rope 8 floats on the river surface, which is convenient for the barrier rope 8 to be frozen together with the ice cover in the early stage of ice cover formation. A tensile skeleton 85 is provided inside the sleeve 81 and a snap ring 86 is provided inside the card interface 82, which further improves the tensile strength of the barrier rope 8.

[0074] As a preferred embodiment, the abdominal bags 83 are connected to each other, the blocking rope 8 is fixed to one end of the protective component 5, and the corresponding abdominal bag 83 can be connected to the inflation pump. The blocking rope 8 extends to one end of the river channel, and the corresponding abdominal bag 83 is connected to a one-way discharge port 84, and a pressure valve is provided inside the one-way discharge port 84.

[0075] It needs to be explained that in the early stage of ice sheet formation, the barrier cable 8 is ensured to be frozen together with the ice sheet. After the ice sheet is broken by the ice-breaking assembly 7 to form ice blocks or the ice sheet melts by itself to form ice blocks, the ice blocks are blocked near the corresponding embankment body 1 under the action of the barrier cable 8 until they melt, which can effectively reduce ice jams, reduce the intensity of ice floods or delay the occurrence of ice floods.

[0076] During specific implementation, when the protective plate 6 is impacted, the central column 533 squeezes the lateral slider 531, and the lateral sliders 531 slide away from each other, and the buffer spring 532 is stretched, specifically, the impact force of the impact on the protective plate 6 is shared by the buffer spring 532. In addition, when the protective plate 6 is impacted, it will synchronously squeeze the adjusting rod 72 through the extension plate 56, causing the adjusting rod 72 to slide and squeeze the compression spring, and the pressure plate squeezes the deflection cam 741. The ice-breaking arm 74 deflects as a whole, and the ice-breaking blade 742 deflects out from the gap of the protective plate 6, squeezing the ice attached to the protective plate 6, so that the large volume of ice is split. In addition, during the formation of the ice sheet, the blocking cable 8 floats on the river surface and can then be frozen in the ice sheet. When the ice sheet is subsequently broken but not completely melted, the blocking cable 8 effectively fixes the ice to prevent the ice from drifting away, blocking the river channel, and causing ice floods.

[0077] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
