Description

Technical Field

[0001] The invention belongs to the technical field of debris flow retaining dams, and in particular relates to a graded filtering device for a debris flow grid retaining dam. Background Art

[0002] A debris flow refers to a special flood carrying large amounts of mud, sand and rocks caused by landslides in mountainous areas or other areas with deep valleys and rugged terrain due to heavy rain, heavy snow or other natural disasters. It is usually blocked by building a retaining dam.

[0030] Specifically, a first limiting groove and a second limiting groove are provided at the bottom of the U-shaped seat 1 , the first limiting groove is plugged into and fitted with the first-level grille 201 , and a detachable retaining dam 5 is installed at the top of the U-shaped seat 1 .

[0031] Furthermore, a first limiting plate 101 is fixedly provided on the side of the U-shaped seat 1 close to the cleaning component 3, a second limiting plate 102 and a third limiting plate 103 are fixedly provided on the top of the first limiting plate 101, and a first electromagnet is installed on one side of the third limiting plate 103 (a protective cover is provided on the top bone of the first limiting plate 101 to reduce damage to the internal structure by the natural environment), a plate inlet 104 is provided on the side of the U-shaped seat 1 close to the first limiting plate 101, a U-shaped positioning frame 105 is fixedly provided on the side of the U-shaped seat 1 away from the first limiting plate 101, a plurality of first openings 202 are provided on the surface of the first-level grille 201, and the filter component 2 also includes a second-level grille 203, which is plugged into the second limiting groove, and a second opening 204 corresponding to the cleaning block 302 is provided on the surface of the second-level grille 203.

When the debris flow flows down, it first hits the first-level grid 201. At this time, the large fallen rocks in the debris flow are blocked by the first-level grid 201, and the debris flow flows out from the first opening 202, and then hits the second-level grid 203. At this time, the small fallen rocks and fallen leaves in the debris flow are blocked by the second-level grid 203, and the debris flow flows out from the second opening 204. The debris flow that has been filtered through multiple stages hits the retaining dam 5. At this time, the silt is blocked on one side of the retaining dam 5. The speed of the debris flow after being blocked by the first-level grid 201 and the second-level grid 203 is slowed down, making it difficult for the retaining dam 5 to be blocked by the debris flow. The safety of the retaining dam 5 is improved. After the impact of the debris flow is over, the silt on one side of the retaining dam 5 is sucked out by a silt suction truck, and then the movable plate 301 is driven to move by the power drive component 4 so that the movable plate 301 enters the U-shaped seat 1. At the same time, the movable plate 301 is controlled to move and fit with the secondary grid 203. At this time, the cleaning block 302 is plugged into the corresponding second opening 204. At this time, the silt and fallen leaves remaining in the second opening 204 are squeezed out by the cleaning block 302, and then the movable plate 301 is controlled to reset. After the movable plate 301 is reset, it continues to clean the remaining fallen rocks and fallen leaves in the U-shaped seat 1.

[0033] Specific embodiment 2, on the basis of specific embodiment 1, a plurality of plug holes 310 are opened on one side of the movable plate 301, and the cleaning component 3 also includes an L-shaped sealing plate 303, a first permanent magnet is installed on one side of the L-shaped sealing plate 303, the first electromagnet and the first permanent magnet are magnetically attracted to each other, the L-shaped sealing plate 303 corresponds to the plate inlet 104, and an elastic reset part 304 is fixedly provided on the other side of the L-shaped sealing plate 303, and one end of the elastic reset part 304 is fixedly connected to the third limit plate 103.

When the second opening 204 on the secondary grille 203 needs to be unblocked, the first electromagnet is controlled to be energized and magnetized. At this time, the L-shaped blocking plate 303 moves to open the inlet 104. During this process, the elastic reset member 304 is compressed, and then the power drive component 4 drives the movable plate 301 to move along the inlet 104 until the plug hole 310 is fully plugged into the plug rod 308. Then, the first motor 309 is driven to drive the driving gear to rotate, and the driving rack 307 is driven to move to drive the L-shaped connecting rod 306 to move, so that the U-shaped movable frame 305 moves and drives the movable plate 301 to move. When the movable plate 301 moves to the secondary grille When the grating 203 is on one side, the cleaning block 302 is plugged into the corresponding second opening 204. When the silt in the secondary grille 203 is squeezed out, the first motor 309 is controlled to rotate in the opposite direction to drive the driving gear to rotate in the opposite direction. The driving rack 307 moves in the opposite direction to drive the L-shaped connecting rod 306 to move in the opposite direction, so that the U-shaped moving frame 305 moves in the opposite direction to drive the moving plate 301 to move in the opposite direction until the moving plate 301 returns to the side of the plate inlet 104 again. At this time, the reverse driving drive assembly 4 drives the moving plate 301 to move, so that the moving plate 301 returns to the initial position, and then the first electromagnet is controlled to be powered off and demagnetized. Under the action of the elastic reset member 304, the L-shaped sealing plate 303 moves toward the plate inlet 104, so that the plate inlet 104 is closed again.

At this time, the fixed plate 402 moves to drive the push-pull bar 401 to move. After being squeezed, the movable plate 301 moves along the plate inlet 104. When the movable plate 301 is completely moved to the inside of the U-shaped seat 1, the movable plate 301 is controlled to dredge the secondary grid 203. When the dredging is completed, the second electromagnet is energized and the second motor 403 is controlled to rotate in the opposite direction. The positioning threaded rod 404 rotates in the opposite direction to drive the fixed plate 402 to move in the opposite direction, so that the push-pull bar 401 moves in the opposite direction and drives the movable plate 301 to move in the opposite direction until the movable plate 301 returns to the initial position.
