[specific embodiment]
Please consult Fig. 1 to Fig. 3 simultaneously, the utility model trashrack trash rake is in order to rubbish and dirt on the removing small hydropower station trashrack, and it comprises holder 1, sliding seat 2, rack take 3, pulley 4, chain 5, pulling bar 6.
This holder 1 comprises two vertical vertical rods 12, be positioned at these two vertical rods, 12 tops and connect this two vertical rod 12 cross bar 14, be positioned at this fixed mount 16 of two vertical rods, 12 middle parts in order to fix this two vertical rod 12, these two vertical rods, 12 inboards are respectively equipped with groove 122.This holder 1 can also comprise a torsion bar 7, and this torsion bar 7 comprises a fixed axis 72, be positioned at these fixed axis 72 two ends can be fixed in the spring 76 that these fixed axis 72, one ends are fixed in this scroll wheel 74 around scroll wheel 74 and two one ends that this fixed axis 72 rotates.
This sliding seat 2 is " H " shape, comprises the vertical bar 22 at two ends and connects the intermediate bar 24 of vertical bar 22.Each fixes a roller 222 four jiaos of outsides of this vertical bar 22, and these rollers 222 are contained in respectively in the groove 122 of this holder 1, and can slide up and down along this groove 122, move up and down thereby drive this sliding seat 2.Each tilts to fix one first stator 242 these intermediate bar 24 two ends, the place, centre position tilts to fix one second stator 246, the direction that this first stator 242 and this second stator 246 tilt is opposite, and this first stator 242 is each fixing a pair of ring 248 that is relatively fixed in the next door, the outside of these two first stators 242.This first stator 242 comprises fixedly connected three, and each correspondence is offered a through hole on its opposite face.
This rack take 3 comprises two vertical fixed legs 32, is positioned at the crossbeam 34 that these fixed leg 32 tops connect this fixed leg 32, and the rake body 36 that is fixed on its bottom perpendicular to this fixed leg 32.The upper end of this fixed leg 32 respectively is provided with a sleeve 322, and this sleeve 322 cooperates with retainer ring 248 on this sliding seat 2.Each is convexly equipped with a connecting piece 342 towards the inboard of rack take 3 these crossbeam 34 two ends, offer a through hole 344 on the vertical one side of this brace 342, the upper end is fixed one 346 in the middle of this crossbeam 34, these axle 346 peripheral sheathed cams 348, this cam 348 can freely rotate around this axle 346, the outstanding respectively pull handle 350 and of fixing ends to piece 352 on these cam 348 relative two sides, offers a fixing hole on this pull handle 350.This rake body 36 is made of the silk of removing contamination of in a row parallel arrangement arranged side by side, and this silk of removing contamination is resilient steel wire bar, thereby it prevents the fracture of himself when can effectively take out stains, and can automatic homing when causing bending when touching hard foreign matter.
This pulley 4 is the design of laborsaving pulley, comprises two interior pulleys 42,44, this chain 5 around should in pulley 42 place, this pulling bar 6 around should in pulley 44 place, be used for pulling should in pulley 44 rotate, thereby drive should in pulley 42 rotate.
During installation, at first this rack take 3 is fixed on this sliding seat 2, this sliding seat 2 is placed in this holder 1 inside again, place torsion bar 7 and pulley 4, chain 5, pulling bar 6 then, its concrete installation steps are as described below.
See also Fig. 2, be fixed to the schematic diagram of sliding seat 2 for rack take 3, at first two sleeves 322 of this rack take 3 are positioned over each retainer ring 248 centre of this sliding seat 2 respectively, use cooperating of a bolt and a nut, this sleeve 322 is fixedlyed connected with retainer ring 248 pivots, thereby this rack take 3 can also tentatively be fixed on this rack take 3 on this sliding seat 2 around these sliding seat 2 rotations.Use an elastic joint part 8 to connect first stator 242 of this sliding seat 2 and the brace 342 of rack take 3 then, this elastic joint part 8 comprises a pair of connection spring 82, this is located at a contiguous block 84 to spring 82 1 ends while hook, offer a screw in the middle of this contiguous block 84, this respectively establishes an annulus to spring 82 other ends, when this elastic joint part 8 is installed, use a bolt 86 to pass the screws of through hole 344 these contiguous blocks 84 centres of back screw-in on this brace 342, after using a bolt 88 to pass the annulus of the through hole of this first stator 242 and these company's spring 82 ends then in addition, use a nut 89 to cooperate, thereby this elastic joint part 8 interconnect this first stator 242 and this brace 342 fixing with this bolt 88.
Four rolling 222 with this sliding seat 2 is placed in the groove 122 of this holder 1 then, this pulley 4 is fixed on cross bar 14 middle parts of this holder 1, this chain 5 is a complete loops, the one end is enclosed within on this interior pulley 42, the other end is enclosed within on the pulley 9 that is positioned at this holder 1 bottom, and its middle part is fixed in the fixing hole of pull handle 350 of this rack take 3.
When using this torsion bar 7, these fixed axis 72 two ends are separately fixed in two vertical rods 12 of this holder 1, respectively twine one section on this each scroll wheel 74 and drive rope 78, the other end of this driving rope 78 is fixed on the sliding seat 2, also can be fixed on this rack take 3.This moment, this pulley 4 was fixed in the middle of this fixed axis 72.
During use, at first spur one side of this pulling bar 6, drive this chain 5 motions, this chain 5 is pulling pull handle 350 downwards, then this pull handle 350 drives this cam 348 rotations, thereby should end to piece 352 and also follow this cam 348 rotations, and in rotation process, contact this second stator 246 gradually, when this pull handle 350 drops to its extreme position, promptly begin to drive this remove contamination target 3 and this sliding seat 2 along this holder 1 to lower slider, should end and support piece 352 ending gradually in these second stator, 246 processes of supporting, gradually that this rack take 3 is extrapolated, thus this rake body 36 outwards sticks up, away from trashrack, thereby promptly prevent to bring rubbish in the trashrack into the trashrack bottom, guaranteed that again rack take 3 arrives the trashrack bottom fast, increases work efficiency.Meanwhile, the spring 82 of this elastic joint part 8 is compressed, and the spring 76 of this torsion bar 7 is twisted gradually.
When this rack take 3 drops to this trashrack bottom, stop drag this pulling bar 6, then spring 82 returns of this elastic joint part 8 drive this rake body 36 and get back to the vertical state of nature, and the silk of respectively removing contamination of promptly harrowing body 36 inserts respectively in the grid of this trashrack.
Thereafter, spur the another side of this pulling bar 6, drive this chain 5 motions, this chain 5 upwards spurs pull handle 350, and this pull handle 350 drives this cam 348 rotations then, then should only also follow this cam 348 to piece 352 and rotate, and in rotation process gradually away from this second stator 246, the silk of respectively removing contamination of this rake body 36 moves up along the grid of this trashrack respectively, promptly the upwards release gradually of the rubbish dirt in this grid, thereby has cleared up trashrack.The spring 76 of the torsion bar 7 that is twisted in rack take 3 decline processes resets gradually, and the power that also provides this sliding seat 2 and this rack take 3 to move upward has been saved the power that uses at the pulling bar.
This pulling bar 6 can or use a motor drives by artificial pulling.This sliding seat 3 moves up and down the mode that can use screw rod.This chain 5 also can use the mode of rope.
