[0032] Please refer to Figure 1-5 In an embodiment of the present invention, a toughness energy dissipation protection device for impact of glacial landslide collapse on a bank slope is provided, comprising:

[0033] Four energy dissipation and pressurization cylinders distributed in a rectangular shape, each of which is provided with an energy dissipation and pressurization component;

[0034] The drive cylinder 3 is connected between two adjacent energy dissipation and pressure cylinders in the horizontal direction, and a rotating shaft 13 is provided inside the drive cylinder 3 for rotation. When the rotating shaft 13 rotates, it can provide energy dissipation and pressure power for the energy dissipation and pressure assembly.

[0035] A rotational energy dissipation assembly 15 is disposed in the drive cylinder 3 and includes at least a ring gear 19. A pull rope 4 is wound around the outside of the ring gear 19. When the ring gear 19 rotates, it can drive the rotating shaft 13 to rotate synchronously.

[0036] An interception net 5, which is connected and supported by the pull rope 4; and

[0037] There are two nozzles 6 symmetrically distributed up and down, and the nozzles 6 are fixed on the interception net 5. High-pressure nozzles 8 are distributed on the nozzles 6. The nozzles 6 are connected to the energy dissipation and pressure cylinder through the liquid supply pipe 7 and are pressurized by the energy dissipation and pressure assembly.

[0038] In this embodiment, when the tough energy dissipation protection device is used to protect the bank slope, the interception net can intercept large ice blocks, and when the ice blocks hit the interception net, they can drive the pull rope to extend out of the drive cylinder 3 through the interception net, and the pull rope is wound on the ring gear 19. Therefore, in the process of the pull rope 4 being pulled out of the drive cylinder 3, the ring gear 19 rotates accordingly and drives the rotating shaft 13 to rotate synchronously. When the rotating shaft 13 rotates, it can provide energy dissipation and pressure power for the energy dissipation and pressure component. At this time, the energy dissipation and pressure component pressurizes the nozzle 6 and causes the liquid in the nozzle 6 to be ejected from the high-pressure nozzle 8. The high-pressure liquid ejected from the high-pressure nozzle 8 can impact the ice blocks, and, in most cases, the high-pressure liquid ejected from the high-pressure nozzle 8 can break up some of the ice blocks, while the incomplete ice blocks greatly reduce the threat to the bank slope.

[0039] In this embodiment, the two energy dissipation pressure cylinders located at the top are the first energy dissipation pressure cylinders 1, which are connected to the bank slope using a first support 10. The two energy dissipation pressure cylinders located at the bottom are the second energy dissipation pressure cylinders 2, which are connected to the bank slope using a second support 11. In order to effectively intercept ice cubes, the first energy dissipation pressure cylinders 1 are higher than sea level and the upper part of the interception net 5 is higher than sea level. In addition, the first support 10 and the second support 11 are both telescopic energy dissipation parts, such as springs, elastic telescopic rods, etc.

[0040] In this embodiment, the energy dissipation and pressurization component includes:

[0041] The lead screw 12 has one end rotatably disposed in the energy dissipation and pressure cylinder, and the other end is connected to the rotating shaft 13;

[0042] a nut 16, which is transmission-connected to the lead screw 12;

[0043] a push plate 17, which is fixedly sleeved on the outside of the nut 16 and is sealingly and slidingly connected to the energy dissipation and pressurization cylinder; and

[0044] The limiting block 18 is fixed to the end of the push plate 17 , and the wall of the energy dissipation and pressurization cylinder is further provided with a limiting groove for sealing and limiting the sliding connection of the limiting block 18 .

[0045] That is to say, when the shaft rotates, the screw rotates accordingly, and the rotation of the screw can drive the push plate 17 to move, thereby pushing the water in the energy dissipation and pressure cylinder and allowing it to enter the nozzle 6, thereby enabling the high-pressure nozzle 8 to spray high-pressure liquid.

[0046] In addition, in this embodiment, a first one-way valve is provided in the liquid supply pipe 7, which allows water to flow from the energy dissipation and pressure cylinder into the liquid supply pipe 7. The bottom of the energy dissipation and pressure cylinder is also connected to a water supply pipe 9, and a second one-way valve is provided in the water supply pipe 9. The second one-way valve allows water to flow from the water supply pipe 9 into the energy dissipation and pressure cylinder.

[0047] Both the first and second one-way valves are one-way valves, also known as non-return valves or check valves. They are valves used for one-way flow. They typically consist of a movable disc or ball and a spring. When fluid flows in the intended direction, the valve opens, allowing passage; when fluid flows in the opposite direction, the valve closes, preventing backflow.

[0048] It should also be noted that, during implementation, the spring force can be configured to be larger, so that the valve will open and allow passage only when the water pressure is greater than a threshold.

[0049] To reset the rotating shaft, ring chambers 14 are provided on both sides of the rotational energy dissipation assembly 15. These ring chambers 14 are fixedly connected to the inner wall of the drive cylinder 3, and torsion springs are provided between the ring chambers 14 and the rotating shaft 13. These torsion springs not only help reset the rotating shaft but also provide energy buffering for the shaft's rotation when the shaft is driven by the pull rope, thereby reducing the impact of ice cubes.

[0050] In this embodiment, the rotational energy dissipation component 15 further includes:

[0051] Three intermediate gears 21 meshing with the ring gear 19;

[0052] Three friction shafts 22 corresponding to the intermediate gears 21, which are fixed between the two ring chambers and are used to rotate and connect the intermediate gears 21; and

[0053] The gear 20 is fixed on the rotating shaft 13 and meshes with the intermediate gear 21 .

[0054] In addition, a friction ring is provided on the inner wall of the intermediate gear 21 .

[0055] Among them, by configuring gears and intermediate gears, the stability of the transmission of the ring gear 19 can be improved, and the multiple intermediate gears configured can also play the role of energy consumption;

[0056] In summary, the tough energy dissipation protection device in the embodiment of the present invention can realize friction energy consumption through the intermediate gear and the friction shaft, and can also realize rotational energy consumption through the torsion spring. The push plate also consumes energy during the pressurization process. The three forms of energy consumption can effectively buffer the ice cubes.

[0057] 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.
