Description

Technical Field

[0001] The present invention relates to the technical field of dam protection, and more particularly to a tough energy dissipation protection device for preventing floating ice and surge waves from impacting moraine dams when ice avalanches are triggered by earthquakes. Background Art

[0002] A moraine dam refers to a dam formed by the blocking of a valley by rocks and debris transported and deposited by glaciers, forming a water retaining body similar to a dam in the valley. It is mainly composed of gravel, sand, silt, clay, etc. It has the characteristics of irregular dam shape, complex structure and material composition, and high non-uniformity. When an earthquake triggers an ice avalanche, it is very easy to collapse under the impact of floating ice and surging waves. It is necessary to carry out risk assessment and emergency disposal of the dam. The existing anti-impact structure has a relatively simple structure and function, and can only reduce the impact of surging waves on the dam. Although the anti-impact structure can withstand the impact of surging waves for a long time, it is easy to be damaged when it is hit by floating ice. Therefore, it is necessary to provide a tough energy dissipation protection device to prevent floating ice and surging waves from impacting the moraine dam when an earthquake triggers an ice avalanche, so as to solve the problems raised in the above background technology. Summary of the Invention

[0003] To achieve the above-mentioned object, the present invention provides the following technical solution: a tough energy dissipation protection device for preventing the impact of floating ice and surge on moraine dams when an earthquake triggers an ice avalanche, comprising:

[0004] dam body;

[0005] Energy dissipation device, installed on the horizontal surface in front of the dam body, provides graded energy dissipation and blocking of floating ice and surges;

[0006] The connecting plate is located between the energy dissipation device and the dam body and is hinged to the energy dissipation device;

[0007] The anti-impact device is fixed to the dam body through a fixing column, and the bottom is hinged to the connecting plate. Under the action of the connecting plate, the energy dissipation device is always connected to the anti-impact device, and the energy dissipation device is kept in a horizontal position.

[0008] Furthermore, preferably, the energy dissipation device includes:

[0009] There are multiple mobile platforms distributed in a straight line, and one end close to the dam body is hinged to the connecting plate to carry the entire energy dissipation device and keep it floating on the water surface;

[0010] The first energy dissipation component is arranged in correspondence with the mobile platform and is fixed at the end of the mobile platform away from the dam body. It mainly dissipates energy from surge waves and provides primary buffering for floating ice.

[0011] The second energy dissipation assembly is fixed on the mobile platform at the end opposite to the first energy dissipation assembly, and is mainly used to dissipate energy from floating ice, while also diverting surges to further reduce the surge impact speed;

[0012] The buffer component is connected to the adjacent first energy dissipation component to assist the first energy dissipation component in dissipating energy.

[0013] Furthermore, preferably, the mobile platform includes:

[0014] The platform surface is set below the horizontal plane in front of the dam body and is connected to the anti-impact device through a connecting plate;

[0015] The positioning block is fixed on the end of the platform away from the dam body;

[0016] The limiting shaft is located above the platform surface, with its two ends respectively connected to the positioning block and the second energy dissipation component;

[0017] A movable block is mounted on the limiting shaft and fixedly connected to the bottom of the first energy dissipation assembly. The movable block is categorized as either slidable or fixed, with different movable blocks positioned at the bottom of adjacent first energy dissipation assemblies. When impacted, while the first energy dissipation assemblies dissipate energy, the intervening first energy dissipation assemblies, driven by the slidable movable block, slide on the limiting shaft, thereby pulling the buffer assembly positioned between the adjacent first energy dissipation assemblies to further buffer and dissipate energy.

[0018] Furthermore, preferably, the first energy dissipation component includes:

[0019] The lifting table is fixed on the moving block and moves with the moving block or remains fixed;

[0020] The energy dissipation block is fixed on the side of the lifting platform and located on top of the positioning block. It protects the side of the lifting platform facing the impact direction and maintains the stability of the bottom.

[0021] The transverse rotating cylinder is rotatably fixed to the top of the lifting platform. When impacted, the energy dissipation block protects the lower portion of the first energy dissipation assembly. During the impact, the transverse rotating cylinder continuously rotates to reduce the impact force of swells and ice floes. Simultaneously, with the assistance of the mobile platform and buffer assembly, multi-level buffering is provided.

[0022] Furthermore, preferably, a compression spring is provided within the lifting platform. When a surge impacts the first energy dissipation assembly, the transverse rotating cylinder continues to rotate, reducing the impact force. When an ice floe impacts the first energy dissipation assembly, the transverse rotating cylinder is subjected to pressure from the ice floe while rotating, causing the compression spring within the lifting platform to compress, causing the transverse rotating cylinder to move downward, initially decelerating the ice floe before it passes through the first energy dissipation assembly.

[0023] Furthermore, preferably, the second energy dissipation component includes:

[0024] The fixed slide rail is fixed on the platform surface and is fixedly connected to the limit shaft;

[0025] A plurality of sliding bases are provided and can be slidably fixed on the fixed slide rail;

[0026] The vertical rotating cylinder is provided corresponding to the sliding base and can be rotatably fixed on the sliding base;

[0027] The adjustment assembly is positioned between adjacent sliding bases. After passing through the first energy dissipation assembly, the ice floe, guided by the vertical rotating cylinder, will always pass through the gaps between the second energy dissipation assemblies. If the ice floe's width is smaller than the spacing between adjacent second energy dissipation assemblies, the ice floe will pass directly through the second energy dissipation assemblies after being guided and buffered by the vertical rotating cylinder. If the ice floe's width is greater than the spacing between adjacent second energy dissipation assemblies, the ice floe will push the second energy dissipation assemblies on both sides toward each other, where it will be buffered and dissipated by the adjustment assembly and the vertical rotating cylinder.

[0028] Furthermore, preferably, the adjustment component includes:

[0029] The telescopic shaft is composed of outer shafts at both ends and an inner shaft in the middle, and the outer shafts at both ends are fixedly connected to the sliding bases on both sides respectively;

[0030] An adjustment spring is mounted on the telescopic shaft, with both ends fixedly connected to the sliding base. When an ice floe, wider than the spacing between adjacent second energy dissipation assemblies, passes between the second energy dissipation assemblies under the buffering guidance of the vertical rotating cylinder, the ice floe pushes the second energy dissipation assemblies on both sides outward. The sliding base then drives the telescopic shaft of the adjustment assembly below the ice floe to extend, stretching the adjustment spring. Simultaneously, the adjustment assemblies connected to the outer sides of the second energy dissipation assemblies on both sides contract under this push. The extension and contraction of the adjustment spring cushions and dissipates energy from the ice floe.

[0031] Furthermore, preferably, the buffer assembly includes:

[0032] A first fixing member is fixed to a side surface of the first energy dissipation component;

[0033] a second fixing member fixed to a side surface of the first energy dissipation assembly adjacent to the first fixing member;

[0034] a first fixing block fixed to one end of the first fixing member;

[0035] A first sliding block is slidably fixed on the first fixing member at one end away from the first fixing block;

[0036] a second fixed block, fixed to one end of the second fixing member and located outside the first sliding block;

[0037] A second sliding block is slidably fixed on the second fixing member at one end away from the second fixing block and is located on the inner side of the first fixing block;

[0038] The elastic member has two ends fixedly connected to the inner sides of the first sliding block and the second sliding block respectively. The two sides of the same first energy dissipation component are respectively connected with the first fixed member and the second fixed member. Taking the first energy dissipation component with a slidable movable block fixed at the bottom as an example, the adjacent first energy dissipation components are fixed on the movable platform, and the left side of the first energy dissipation component is fixedly connected with the second fixed member, and the right side is fixedly connected with the first fixed member. When the first energy dissipation component is impacted, it slides on the movable platform, and then the second fixed member on the left side drives the second fixed block to push the first sliding block. At the same time, the second sliding block slides on the second fixed member under the restriction of the first fixed block, thereby compressing the elastic member; at the same time, the first fixed member on the right side drives the first fixed block to move, and at the same time drives the first sliding block to compress the elastic member, and then under the rebound action of the elastic members on both sides, the impact force of the floating ice and the surging waves is buffered and energy dissipated.

[0039] Furthermore, preferably, the anti-shock device includes:

[0040] The impact plate is divided into two parts, the upper and lower parts, which are hinged together, and the hinge is fixed on the fixed column;

[0041] The elastic connecting plate has two ends that can be slidably arranged within the upper and lower impact plates. The impact plates form a V-shaped angle, and the intersection between the upper and lower impact plates can only rotate inward and cannot expand the angle. As the horizontal plane changes, when floating ice and swells impact the middle part of the impact protection device, the elastic connecting plate deforms toward the middle part, and at the same time, the two ends of the elastic connecting plate slide within the upper and lower impact plates, driving the impact plates to close toward the middle part to intercept. When floating ice and swells impact the upper or lower part of the impact protection device, the impacted end of the elastic connecting plate slides on the impact plate, and then the elastic connecting plate forms a guide arc surface, guiding the floating ice and swells toward the unimpacted end of the elastic connecting plate, and then returning to the horizontal plane, avoiding impact on the dam body.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] In the present invention, multi-stage energy dissipation is performed on surges and floating ice through the energy dissipation device. The first energy dissipation component mainly dissipates energy from surges, and the second energy dissipation component mainly dissipates energy from floating ice. They cooperate with each other, are more targeted, and improve the service life of the protective device.

[0044] In the present invention, by setting up the anti-impact device, floating ice and surging waves are intercepted to prevent floating ice and surging waves from directly impacting the dam body and causing damage to the dam body. Under the action of the elastic connecting plate, according to the different heights of the horizontal plane and different impact positions, the elastic connecting plate bends and slides on the impact plate at the same time to dissipate energy and reduce the damage to the protective device caused by the impact.

DETAILED DESCRIPTION

[0052] See also Figures 1 to 6In an embodiment of the present invention, a tough energy dissipation protection device for preventing floating ice and surge waves from impacting a moraine dam when an earthquake triggers an ice avalanche comprises:

[0053] Dam body 1;

[0054] The energy dissipation device 2 is arranged on the horizontal surface in front of the dam body 1 to dissipate energy of floating ice and swells in a graded manner;

[0055] The connecting plate 3 is located between the energy dissipation device 2 and the dam body 1 and is hinged to the energy dissipation device 2;

[0056] The anti-impact device 4 is fixed to the dam body 1 through the fixing column 5, and the bottom is hinged to the connecting plate 3. Under the action of the connecting plate 3, the energy dissipation device 2 is always connected to the anti-impact device 4, and the energy dissipation device 2 is kept in a horizontal position.

[0057] In this embodiment, the energy dissipation device 2 includes:

[0058] There are multiple mobile platforms 21 distributed in a straight line, and one end of the mobile platform 21 adjacent to the dam body 1 is hinged to the connecting plate 3, supporting the energy dissipation device 2 as a whole and keeping the energy dissipation device 2 floating on the water surface;

[0059] The first energy dissipation assembly 22 is provided corresponding to the mobile platform 21 and is fixed to the end of the mobile platform 21 away from the dam body 1. It mainly dissipates energy from surge waves and provides primary buffering for floating ice.

[0060] The second energy dissipation assembly 23 is fixed on the mobile platform 21 at the end opposite to the first energy dissipation assembly 22, and is mainly used to dissipate energy from floating ice and divert swells to further reduce the impact speed of swells.

[0061] The buffer assembly 24 is connected to the adjacent first energy dissipation assembly 22 to assist the first energy dissipation assembly 22 in dissipating energy.

[0062] In this embodiment, the mobile platform 21 includes:

[0063] The platform surface 211 is provided below the horizontal plane in front of the dam body 1 and is connected to the anti-impact device 4 via the connecting plate 3;

[0064] A positioning block 212 is fixed on the end of the platform surface 211 away from the dam body 1;

[0065] The limiting shaft 213 is located above the platform surface 211, and its two ends are respectively connected to the positioning block 212 and the second energy dissipation component 23;

[0066] The movable block 214 is mounted on the limiting shaft 213 and fixedly connected to the bottom of the first energy dissipation assembly 22. The movable blocks 214 are slidable and fixed, with different movable blocks 214 being installed at the bottom of adjacent first energy dissipation assemblies 22. When impacted, while the first energy dissipation assemblies 22 dissipate energy, the spaced first energy dissipation assemblies 22, driven by the slidable movable blocks 214, slide on the limiting shaft 213, thereby pulling the buffer assembly 24 disposed between the adjacent first energy dissipation assemblies 22 to further buffer and dissipate energy.

[0067] In this embodiment, the first energy dissipation component 22 includes:

[0068] The lifting platform 221 is fixed on the moving block 214 and moves along with the moving block 214 or remains fixed;

[0069] The energy dissipation block 222 is fixed to the side of the lifting platform 221 and is located on top of the positioning block 212 to protect the side of the lifting platform 221 facing the impact direction and maintain the stability of the bottom;

[0070] The transverse rotating cylinder 223 is rotatably fixed to the top of the lifting platform 221. When impacted, the energy dissipation block 222 protects the lower portion of the first energy dissipation assembly 22. The transverse rotating cylinder 223 continuously rotates during the impact to reduce the impact force of swells and ice floes. Simultaneously, with the assistance of the mobile platform 21 and the buffer assembly 24, multi-level buffering is provided.

[0071] In this embodiment, a compression spring 2211 is installed inside the lifting platform 221. When a surge impacts the first energy dissipation assembly 22, the transverse rotating cylinder 223 rotates continuously to reduce the impact force. When floating ice impacts the first energy dissipation assembly 22, the transverse rotating cylinder 223 is subjected to pressure from the floating ice while rotating, which in turn compresses the compression spring 2211 inside the lifting platform 221, causing the transverse rotating cylinder 223 to move downward. After initially decelerating the floating ice, the floating ice passes through the first energy dissipation assembly 22.

[0072] In this embodiment, the second energy dissipation component 23 includes:

[0073] The fixed slide rail 231 is fixed on the platform surface 211 and is fixedly connected to the limiting shaft 213;

[0074] A plurality of sliding bases 232 are provided and can be slidably fixed on the fixed rail 231;

[0075] The vertical rotating cylinder 233 is provided corresponding to the sliding base 232 and can be rotatably fixed on the sliding base 232;

[0076] Adjustment assemblies 234 are positioned between adjacent sliding bases 232. After passing through the first energy dissipation assemblies 22, the ice floe, guided by the vertical rotating cylinders 233, will always pass through the spaces between the second energy dissipation assemblies 23. If the ice floe's width is smaller than the spacing between adjacent second energy dissipation assemblies 23, the ice floe will pass directly through the second energy dissipation assemblies 23 after being guided and buffered by the vertical rotating cylinders 233. If the ice floe's width is greater than the spacing between adjacent second energy dissipation assemblies 23, the ice floe will push the second energy dissipation assemblies 23 toward each other, where it will be buffered and dissipated by the adjustment assemblies 234 and the vertical rotating cylinders 233.

[0077] In this embodiment, the adjustment component 234 includes:

[0078] The telescopic shaft 2341 is composed of two outer shafts at both ends and an inner shaft in the middle, and the two outer shafts are fixedly connected to the sliding bases 232 on both sides respectively;

[0079] Adjustment spring 2342 is sleeved on telescopic shaft 2341, with both ends fixedly connected to sliding base 232. When an ice floe, wider than the distance between adjacent second energy dissipation assemblies 23, passes between the second energy dissipation assemblies 23 under the buffering guidance of vertical rotating cylinder 233, the ice floe pushes the second energy dissipation assemblies 23 on both sides outward. The sliding base 232 then drives the telescopic shaft 2341 of the adjustment assembly 234 below the ice floe to extend, stretching adjustment spring 2342. Simultaneously, the adjustment assemblies 234 connected to the outer sides of the second energy dissipation assemblies 23 on both sides contract under this push. Under the extension and contraction of adjustment spring 2342, the ice floe is buffered and energy dissipated.

[0080] In this embodiment, the buffer assembly 24 includes:

[0081] A first fixing member 241 is fixed to the side of the first energy dissipation component 22;

[0082] A second fixing member 242 is fixed to a side surface of the first energy dissipation assembly 22 adjacent to the first fixing member 241;

[0083] A first fixing block 243 fixed to one end of the first fixing member 241;

[0084] A first sliding block 244 is slidably fixed on the first fixing member 241 at an end away from the first fixing block 243;

[0085] A second fixing block 245 is fixed to one end of the second fixing member 242 and is located outside the first sliding block 244;

[0086] The second sliding block 246 is slidably fixed on the second fixing member 242 at one end away from the second fixing block 245 and is located inside the first fixing block 243;

[0087] The elastic member 247 has two ends fixedly connected to the inner sides of the first sliding block 244 and the second sliding block 246 respectively. The two sides of the same first energy dissipation component 22 are respectively connected to the first fixing member 241 and the second fixing member 242. Taking the first energy dissipation component 22 with a slidable movable block 214 fixed at the bottom as an example, the adjacent first energy dissipation components 22 are fixed on the movable platform 21. The left side of the first energy dissipation component 22 is fixedly connected to the second fixing member 242, and the right side is fixedly connected to the first fixing member 241. When the first energy dissipation component 22 is impacted, it slides on the movable platform 21, and then the second fixing member 242 on the left side drives the second fixing block 245 to push the first sliding block 244. At the same time, the second sliding block 246 slides on the second fixing member 242 under the restriction of the first fixing block 243, thereby compressing the elastic member 247; at the same time, the first fixing member 241 on the right side drives the first fixed block 243 to move, and at the same time drives the first sliding block 244 to compress the elastic member 247, and then under the rebound action of the elastic members 247 on both sides, the impact force of the floating ice and the surge is buffered and dissipated.

[0088] Then the elastic member 247 is compressed.

[0089] In this embodiment, the anti-shock device 4 includes:

[0090] The impact plate 41 is divided into two parts, the upper and lower parts, which are hinged together, and the hinge is fixed on the fixed column 5;

[0091] The elastic connecting plate 42 has two ends that are slidably disposed within the upper and lower impact plates 41. The impact plates 41 form a V-shaped angle, and the junction between the upper and lower impact plates 41 can only rotate inward and cannot expand the angle. As the horizontal plane changes, when floating ice and swells impact the middle part of the impact-proof device 4, the elastic connecting plate 42 deforms toward the middle part, and at the same time, the two ends of the elastic connecting plate 42 slide within the upper and lower impact plates 41, driving the impact plates 41 to close toward the middle part to intercept; when floating ice and swells impact the upper or lower part of the impact-proof device 4, the impacted end of the elastic connecting plate 42 slides on the impact plate 41, and then the elastic connecting plate 42 forms a guide arc surface, guiding the floating ice and swells to the unimpacted end of the elastic connecting plate 42, and then returning to the horizontal plane, avoiding impact on the dam body 1.

[0092] In specific implementation, when the ice floes and the surge hit each other, the first energy dissipation assembly 22 in the energy dissipation device 2 will first dissipate the energy, and the surge below the horizontal surface will be buffered by the energy dissipation block 222, while protecting the first energy dissipation assembly 22. Then, under the joint action of the horizontal rotating cylinder 223, the buffer assembly 24 and the mobile platform 21, the surge will be mainly buffered and energy dissipated, and then the ice floes will be decelerated under the action of the lifting platform 221. After passing through the first energy dissipation assembly 22, the surge will be diverted and buffered under the action of the vertical rotating cylinder 233 in the second energy dissipation assembly 23. At the same time, the regulating assembly 22 will be used to adjust the flow of the surge. Under the action of component 234, the floating ice is intercepted and slowed down again, and then the floating ice and swells collide with the anti-impact device 4, and according to the different horizontal planes, they collide with different positions on the elastic connecting plate 42 to provide protection. When the floating ice and swells impact the middle part of the anti-impact device 4, the elastic connecting plate 42 deforms toward the middle part, and the impact plate 41 closes toward the middle part to provide protection. When the floating ice and swells impact the upper or lower part of the anti-impact device 4, the elastic connecting plate 42 guides and protects. The floating ice and swells are returned to the water surface through the arc path generated by the deformation of the elastic connecting plate 42, completing the protection work.

[0093] 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.
