Description

Technical Field

[0001] This invention belongs to the field of dam protection technology, specifically a device for preventing the impact of landslide surge waves on dam structures. Background Technology

[0002] Landslide surge disasters are caused by a landslide of a certain volume impacting a certain volume of water at a certain speed. This can damage downstream water-retaining structures. In severe cases, landslide surges may overflow the dam crest or cause the dam to collapse, resulting in serious casualties and property damage.

[0003] To date, the main methods to prevent landslides from overflowing the dam crest or causing dam failure are to install anti-impact devices on the dam body or increase the height of the dam. However, traditional anti-impact devices are prone to damage after long-term use and are inconvenient to replace. Increasing the height of the dam body, on the other hand, increases the investment in dam construction.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] Example 1

[0029] Reference Figures 1-6 A device for preventing the impact of landslide surge waves on dam structures, comprising:

[0030] Dam body 1 and slope 2, with slope 2 located on one side of dam body 1;

[0031] A guiding assembly, located on the outer wall of dam body 1, includes: a buffer plate 4, a guide plate 5, an impact plate 6, a resistance plate 7, a buffer frame 15, a fixing rod 16, a bolt 21, a tension spring 22, an auxiliary rod 23, an adjusting bolt 24, and auxiliary components. The auxiliary components, located on the outer wall of dam body 1, are used to counteract the direct impact of surging waves on slope 2 and dam body 1. The bolt 21 is rotatably embedded in the central opening of the inner wall of the buffer plate 4, providing stable support for the tension spring 22 and ensuring installation stability. One end of the tension spring 22 is fixedly attached to one end of the bolt 21, and the other end is fixedly attached to the outer wall of the auxiliary rod 23. The adjusting bolt 24 is threadedly connected to the inner wall of the auxiliary rod 23. 4. A nut is used to adjust the working position of the buffer frame 15. The buffer frame 15 is threaded to one end of the adjusting bolt 24. The buffer frame 15 and the fixing rod 16 can transmit the impact force generated by the guide plate 5. One end of the fixing rod 16 is fixed to the outer wall of the buffer frame 15, and the other end of the fixing rod 16 is fixed to the outer wall of the guide plate 5. The resistance plate 7 is fixed to the outer wall of the impact plate 6. The resistance plate 7 can guide the surging waves into turbulence and improve the wave blocking efficiency. The buffer assembly is set on the water surface. The buffer assembly includes a floating plate 3, a connecting steel rope 8, a support plate 301, a rotating plate 302, an auxiliary spring 303, a mounting hole 304, and an anchoring assembly. In actual application, the floating plate 3 needs to be... Additional reflective strips are attached to assist staff in observing swells at night. The anchoring components are installed on the corresponding bank slopes of the dam body 1 on both sides. The support plate 301 is fixedly installed on the top of the outer wall of the floating plate 3. The rotating plate 302 is rotatably embedded in the outer wall of the support plate 301. The rotating plate 302 can achieve efficient swell blocking. One end of the auxiliary spring 303 is fixedly installed on the outer wall of the rotating plate 302. The auxiliary spring 303 can ensure stable support for the rotating plate 302, ensure the rapid reset of the rotating plate 302, and continuously block the swell. The other end of the auxiliary spring 303 is fixedly installed on the outer wall of the support plate 301. The mounting hole 304 is opened on the inner wall of the floating plate 3. The mounting hole 304 matches the connecting steel cable 8. When the swell occurs... During the surge, the lifting rings 28 and anchor bolts 26 installed on the bank slope first restrict the connecting steel rope 8. The floating plate 3 floats on the water surface during the surge. Then, the surge impacts the rotating plate 302, causing the auxiliary spring 303 to be compressed, weakening the impact force of the surge. Subsequently, the auxiliary spring 303 causes the rotating plate 302 to return to its original position, intercepting the next wave of surge. Before the surge impacts the dam body 1, the surge first hits the impact plate 6 and the resistance plate 7. The resistance plate 7 disrupts the flow of the surge and transmits the impact force using the support platform 18. The rubber sleeve 19 and the secondary spring 20 complete the initial buffering. Then, the impact force is transmitted to the buffer plate 4, and the fixed plate 12 and the buffer spring 11 complete the second buffering. When the surge hits the guide plate 5, it drives the buffer frame 15 and the fixed rod 16.This causes the buffer frame 15 to move away from the adjusting bolt 24 and auxiliary rod 23, disengaging them from the buffer plate 4. Combined with the tension spring 22, this further buffers the swell. Simultaneously, the special shape of the guide plate 5 guides the swell to impact the water surface, further preventing it from striking the dam body 1.

[0032] Reference Figures 1-6 The auxiliary components include mounting plate 9, main buffer cylinder 10, buffer spring 11, fixing plate 12, adjusting plate 13, adjusting bolt 14, limiting plate 17, support platform 18, rubber sleeve 19 and secondary spring 20. The buffer spring 11 can achieve efficient buffering, and the buffer spring 11 needs to be rust-proofed. The anchoring components include casting block 25, anchor rod 26, anchor head 27 and lifting ring 28.

[0033] Reference Figures 1-6 Mounting plate 9 is fixed to the outer wall of dam body 1 by bolts. Main buffer cylinder 10 is fixed to the outer wall of mounting plate 9. Fixing plate 12 is slidably embedded in the inner wall of main buffer cylinder 10. Fixing plate 12 can achieve stable installation of buffer plate 4. Adjusting plate 13 is slidably sleeved on the protruding corner of fixing plate 12. One end of adjusting bolt 14 is threaded to the inner center of fixing plate 12 and adjusting plate 13. One end of buffer spring 11 is overhanging on the outer wall of mounting plate 9. The other end of buffer spring 11 is fixed to the bottom of outer wall of adjusting plate 13. Limiting plate 17 is fixed to the top corner of outer wall of buffer plate 4. Support platform 18 is slidably embedded in inner wall of limiting plate 17. One end of secondary spring 20 is fixed to outer wall of limiting plate 17. The other end of spring 20 is fixedly installed at the center of the bottom of the outer wall of support platform 18. Rubber sleeve 19 is rotatably fitted onto the outer wall of secondary spring 20. Cast block 25 is embedded in the bank slope. Anchor rod 26 is embedded in the inner wall of cast block 25. Anchor head 27 is fitted onto the outer wall of anchor rod 26. Lifting ring 28 is fixedly installed at the top of anchor rod 26. Connecting steel rope 8 is wrapped around the outer wall of lifting ring 28. Impact plate 6 is fixedly installed on the outer wall of support platform 18. One end of guide plate 5 is curved in an arc shape. The cross-section of resistance plate 7 is V-shaped. The 16 buffer components are connected together by horizontal and vertical steel ropes to form a four-row, four-column structure. The two outer rows of buffer components are connected to the lifting ring 28 on both bank slopes by connecting steel ropes, thereby fixing the 16 buffer components on the water surface. Figure 2 As shown, the anchor head 27 of the anchoring assembly is inserted into the bank slope.

[0034] Working principle: When a surge occurs, the lifting rings 28 and anchor bolts 26 installed on the bank slope first restrict the connecting steel rope 8, causing the floating plate 3 to float on the water surface during the surge. Subsequently, the surge impacts the rotating plate 302, compressing the auxiliary spring 303 and weakening the impact force of the surge. Then, the auxiliary spring 303 causes the rotating plate 302 to return to its original position, intercepting the next wave of surge. Before the surge impacts the dam body 1, it first strikes the impact plate 6 and the resistance plate 7. The resistance plate 7 disrupts the water flow of the surge while simultaneously using the support platform 18 to transmit the water flow. The impact force is initially buffered by the rubber sleeve 19 and the secondary spring 20. Then the impact force is transmitted to the buffer plate 4, and the second buffer is completed by the fixed plate 12 and the buffer spring 11. When the surge hits the guide plate 5, it drives the buffer frame 15 and the fixed rod 16, causing the buffer frame 15 to pull the adjusting bolt 24 and the auxiliary rod 23 away from the buffer plate 4. Combined with the tension spring 22, the surge is buffered again. At the same time, combined with the special shape of the guide plate 5, the surge is guided to impact the water surface, further preventing the surge from hitting the dam body 1.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
