DETAILED DESCRIPTION

[0037] See also Figure 1-4The present invention provides a device for preventing the impact of ice lake burst flood and ice mixture on the super-large diameter pipeline structure, comprising: a flood discharge pipe 1, an ice block block component 2 is provided at the water inlet of the flood discharge pipe 1, which can buffer the impact of ice blocks in the water flow and can block large-volume ice blocks to the outside of the flood discharge pipe 1, a plurality of slide rails 3 are fixedly provided at the bottom end of the inner part of the flood discharge pipe 1 along the water flow direction, a fixed seat 4 is fixedly provided on the side of the slide rail 3 away from the ice block block component 2, a sliding block 5 is slidably provided on the slide rail 3, a baffle 6 is hinged on the sliding block 5, and a certain resistance to the water flow is generated, an ice crushing component 9 is provided on the baffle 6, and the ice in the water flow is crushed, and an angle adjustment cylinder 7 is hinged on the fixed seat 4, and the angle adjustment cylinder 7 is hinged to the baffle 6, and the angle of the baffle 6 can be controlled to change the resistance to the water flow.

[0038] In this embodiment, a large buffer spring 8 is arranged between the sliding block 5 and the fixing seat 4 , which can generate an impulse force against the water flow on the sliding block 5 .

[0039] In this embodiment, when the large buffer spring 8 is compressed to the limit position, the angle adjustment cylinder 7 is shortened, so that the baffle 6 can be adjusted to be parallel to the water flow, and when the sliding block 5 moves away from the fixed seat 4, the large buffer spring 8 continues to extend.

[0040] It needs to be explained that, when the baffle 6 drives the sliding block 5 to overcome the elastic force of the large buffer spring 8 and approach the extreme position of the fixed seat 4 under the impact of the water flow, the baffle 6 is made parallel to the water flow by controlling the angle adjustment cylinder 7, and the impact force of the water flow on the baffle 6 is sharply reduced. Under the elastic force of the large buffer spring 8, the sliding block 5 moves away from the fixed seat 4. In the process of the sliding block 5 moving away from the fixed seat 4, the angle adjustment cylinder 7 continues to extend, which on the one hand generates a thrust against the water flow on the sliding block 5, and on the other hand, pushes the water flow in the flood discharge pipe 1 outward by increasing the angle between the water flow and the baffle 6.

[0041] In this embodiment, the ice blocking assembly 2 includes:

[0042] The annular outer ring 21 is fixed to the inner wall of the water inlet of the flood discharge pipe 1;

[0043] An ice-blocking column 22 is fixed inside the annular outer ring 21 perpendicular to the water flow direction, and a plurality of ice-blocking columns 22 are linearly arranged to block large-volume ice blocks from reaching the outside of the flood discharge pipe 1; and

[0044] The floating energy dissipation block assembly 23 is slidably disposed on the ice-blocking column 22 , and can buffer the impact of ice blocks on the ice-blocking column 22 .

[0045] It should be explained that the floating energy dissipation block assembly 23 can slide on the ice-blocking column 22, and the floating energy dissipation block assembly 23 can float on the water surface. A plurality of independent floating energy dissipation block assemblies 23 can form a buffer zone under the change of water level. On the one hand, it can buffer the impact of ice blocks on the ice-blocking column 22. On the other hand, only one floating energy dissipation block assembly 23 is configured for each ice-blocking column 22, which will not affect the water flow entering the flood discharge pipe 1.

[0046] In this embodiment, the floating energy dissipation block assembly 23 includes:

[0047] A floating slider 231 is slidably embedded in the outer wall of the ice-blocking column 22;

[0048] An energy dissipation housing 232 is fixed on the floating slider 231; and

[0049] The floating block 233 is fixed on the side of the energy dissipation shell 232 close to the water surface, and can drive the energy dissipation shell 232 to float on the water surface.

[0050] In this embodiment, the floating energy dissipation block assembly 23 further includes:

[0051] An impact layer 234 is fixed to a side of the energy dissipation housing 232 away from the floating slider 231;

[0052] The impact block 235 is disposed inside the energy shell 232 and fixed in the middle of the impact layer 234;

[0053] A vertical buffer spring 236 is disposed between the impact block 235 and the bottom of the energy dissipation housing 232;

[0054] Side rails 237 are symmetrically arranged on both sides between the bottom of the energy dissipation shell 232;

[0055] A side energy dissipation slider 238 is slidably disposed on the side track 237;

[0056] A lateral connecting rod 239, one end of which is hinged to the impact block 235 and the other end of which is hinged to the lateral energy dissipation slider 238;

[0057] A lateral buffer spring 2310 is disposed between the lateral energy dissipation slider 238 and the side wall of the energy dissipation housing 232; and

[0058] The impact plate 2311 has one end hinged to the side wall of the energy dissipation housing 232 and the other end hinged to one end of the impact block 235 away from the side buffer spring 2310 .

[0059] It needs to be explained that the impact layer 234 is made of a flexible material such as rubber. Under the impact of ice cubes, it will deform toward the side close to the impact plate 2311, and transmit the impact force to the impact plate 2311. The impact plate 2311 drives the impact block 235 to overcome the elastic force of the vertical buffer spring 236 and move toward the bottom of the energy dissipation shell 232. The side connecting rod 239 can transfer the excess impact force to the side buffer spring 2310 for energy dissipation through the side energy dissipation slider 238.

[0060] In this embodiment, the ice crushing assembly 9 includes:

[0061] An ice-breaking shell 91 is fixed on the baffle 6;

[0062] The propeller 92 is rotatably arranged linearly outside the ice-breaking housing 91 and can break small ice cubes in the flood discharge pipe 1;

[0063] A buffer plate 93 is slidably disposed at the center of the outer side of the propeller 92; and

[0064] A small buffer spring 94 is disposed between the outer side of the propeller 92 and the buffer plate 93 to buffer the impact of small ice cubes.

[0065] It should be explained that the crushing blades of the propeller 92 are arranged obliquely, and the small ice cubes that hit the buffer plate 93 are crushed under the high-speed rotation of the propeller 92, thereby preventing the ice cubes from hitting the side wall of the flood discharge pipe 1.

[0066] When implementing

[0067] Ice cubes enter the flood discharge pipe 1 along with the water flow, and the floating energy dissipation block assembly 23 forms a buffer zone on the water surface under the change of the water surface. The ice cubes collide with the floating energy dissipation block assembly 23 to dissipate energy, and large ice cubes are blocked outside the flood discharge pipe 1. Small ice cubes pass through the ice blocking column 22 and reach the baffle 6, and are crushed under the high-speed rotation of the propeller 92.

[0068] When the baffle plate 6 drives the sliding block 5 to overcome the elastic force of the large buffer spring 8 and approach the limit position of the fixed seat 4 under the impact of the water flow, the angle adjustment cylinder 7 contracts to make the baffle plate 6 parallel to the water flow, and the impact force of the water flow on the baffle plate 6 is sharply reduced. Under the elastic force of the large buffer spring 8, the sliding block 5 moves away from the fixed seat 4. When the sliding block 5 moves away from the fixed seat 4, the large buffer spring 8 continues to extend, and the baffle plate 6 pushes the water flow out of the flood discharge pipe 1 to disperse the ice accumulated at the entrance of the flood discharge pipe 1.

[0069] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
