Problems solved by technology

However, the grab bucket for cleaning the trash can’t solve the problem of the sticking of branches and trunks between the upper grid holes of the trash rack. There are two common methods. Lift out the orifice, and manually remove the blockage in the grid hole; another method is to wait for the annual fixed maintenance period, lift each trash rack out of the orifice, and then manually remove it. Using these two methods, for the hydropower station to shut down and clean, All will cause considerable economic losses, and the blockages such as branches and trunks stuck in the grid holes are difficult to pull out

Embodiment 1

[0043] Such as Figures 1 to 7 As shown, a trash rack plugging material extraction device includes a balance beam 1, a lifting device 2 that moves horizontally is arranged on the balance beam 1, and a clamping device 3 that moves up and down is connected below the lifting device 2, The clamping device 3 includes a mobile clamping device 4 and a rotary clamping device 5, the mobile clamping device 4 approaches or moves away from the rotary clamping device 5 after clamping the blockage, and the rotary clamping device 5 will move The blockage held by the clamping device 4 is picked up and pulled out.

[0044] The blockage in the grid hole 10 is pulled out by the clamp A43, the clamp B52 clamps and rotates the pulled out blockage by 90°, and the blockage is completely separated from the grid hole 10 with the rotation, and the clamp A43 is close to the grid The hole 10 pulls out the remaining blockage. Under the normal operation state of the generator set, the effect of automaticall...

Embodiment 2

[0046] Such as Figures 1 to 7 As shown, a trash rack plugging material extraction device includes a balance beam 1, a lifting device 2 that moves horizontally is arranged on the balance beam 1, and a clamping device 3 that moves up and down is connected below the lifting device 2, The clamping device 3 includes a mobile clamping device 4 and a rotary clamping device 5, the mobile clamping device 4 approaches or moves away from the rotary clamping device 5 after clamping the blockage, and the rotary clamping device 5 will move The blockage held by the clamping device 4 is picked up and pulled out.

[0047] Described lifting device 2 comprises slide plate 21, I-beam 22, motor B28 and pulley 29, and the upper end of described slide plate 21 is provided with the roller 23 that rolls along the length direction of I-beam 22, and the lower end is provided with motor A24, and described motor At least two reels 25 are fixed on the rotating shaft of A24, the upper end of the steel wir...

Abstract

The invention discloses a trash rack obstruction pulling device and a trash rack obstruction pulling method. The trash rack obstruction pulling device comprises a balance beam, wherein a hoisting device which moves horizontally is arranged on the balance beam, a clamping device which moves up and down is connected below the hoisting device, the clamping device comprises a movable clamping device and a rotary clamping device, the movable clamping device clamps obstructions, and then moves close to or far away from the rotary clamping device, and the rotary clamping device picks up and pulls theobstructions clamped by the movable clamping device. The trash rack obstruction pulling device pulls out the obstructions in rack holes through clamp forceps A, then uses clamp forceps B for clampingthe obstructions pulled out and rotating the obstructions by 90 degrees, enables the obstructions to completely break away from the rack holes along with rotation, then enables the clamp forceps A tomove close to the rack holes so as to pull out the residual obstructions, achieves the function of automatically clearing the obstructions in the rack holes under the normal running state of a generator set, prevents loss from being caused by halt needed in manual clearing, and solves the puzzle that a trash rack is blocked by tree branches, tree trunks and the like.

Description

technical field [0001] The invention belongs to the technical field of water conservancy equipment cleaning, and in particular relates to a device and method for pulling out trash rack blockages. Background technique [0002] In water conservancy and hydropower projects, especially in hydropower stations, the trash rack is used as the first barrier of the water inlet of the generator set. Its function is mainly to intercept floating dirt in the water and prevent blockages from flowing into the generator set through the water inlet. During the flood season every year, a large number of blockages accumulate in front of the trash rack at the water inlet. If there are too many blockages in the inlet holes between the leaves of the trash rack, especially the blockage of branches and trunks, it will not only cause pressure on the front and back of the trash rack. If the difference is too large, it will also affect the inflow of the generator set, and even damage the trash rack. On...
