Chain conveyer is formed, including：First drive sprocket 26, the second driven sprocket 24, the first driving chain 25, the 3rd driven sprocket
8th, the 4th driven sprocket 6, the second driving chain 7 and power transmission shaft.The second driven sprocket 24 and are fixed in the both ends of power transmission shaft 23 respectively
Three driven sprockets 8；The first drive sprocket 26 and the 5th drive sprocket 5 are fixed with drive shaft 29, shaft end is provided with motor 27；The
One drive sprocket 26, the second driven sprocket 7, the first driving chain 25 form first order Chain conveyer, the 3rd driven sprocket the 8, the 4th
Driven sprocket 6, the second driving chain 7 form second level Chain conveyer, and motor 27 drives drive shaft 29 and by the first order chain during work
Motion and power can be delivered separately to two the 5th by transmission through transmission shaft driven to second level Chain conveyer, this two-stage Chain conveyer
Drive sprocket 5；Draw-gear is made up of two sets of longitudinally displaced Chain conveyers, and by motor 27, actuator drives, its is same during work
Step operation.Chain conveyer is often covered mainly by the 5th drive sprocket 5, the 6th driven sprocket 6, the 7th driven sprocket 18, the 8th driven chain
Wheel 20, conduction chain 9, the composition such as guide rail 11, this four sprocket wheels and a secondary chain form flat deposited rectangular configuration, wherein the of one end
Five drive sprockets 5 and the 3 upper and lower distribution of the 6th driven sprocket are simultaneously arranged on fixed frame 4, two the 7th driven chains of the other end
The driven sprocket 20 of wheel 18 and the 8th is also upper and lower to be distributed and installed in the tensioning sliding rack 19 for being used for the tensioning of conduction chain 9；Two sets
Chain conveyer shares a tensioning apparatus 21 for being fixed on pontoon bridge side, is easy to synchronous tension；The drawing piece 21-1 of tensioning apparatus 21
For U-shape structure, both ends are tensioned sliding rack 19 respectively at two and are fixedly connected, consolidate in the middle part of drawing piece 21-1 with leading screw 21-4 one end
Fixed, the leading screw 21-4 other ends screw in the screw supporting with it after passing through the via being fixed on the tensioning support 21-2 of floating side
21-3 is simultaneously adjacent to being tensioned support 21-2, when rotating screw 21-3 (unshifting) driving leading screw 21-4 displacements (not rotating), i.e.,
Tensioning sliding rack 19 can be dragged to move in foundation bolt sliding groove 31, and then realize the tensioning of conduction chain；Linked network axle 30 is worn
Conduction chain attached plate hole is crossed, both ends are separately installed with guide wheel 10 and roller, and guide wheel 10 runs in the neck of guide rail 22, is primarily subjected to
Garbage barrier net blocks the axial force acted on during dirt on linked network axle 30, and roller is run in guide rail 22, is primarily subjected to act on linked network axle
Radial load on 30.The effect of guide wheel 10 and roller is resistance when reducing draw-gear work；Linked network between centers every it is appropriate away from
It is arranged on two conduction chains from corresponding, in the change 32 of the linked network axle 30 on the conduction chain correspondence position of both sides, is connected with
Steel wire rope 17, the laying installation of garbage barrier net 16 is on steel wire rope 17, and when garbage barrier net 16 blocks dirty work in water, steel wire rope 17 carries
Water resistance is blocked suffered by garbage barrier net 16, prevents the stress of garbage barrier net 16 from damaging.In addition, when conduction chain is run to arc trajectory,
Steel wire rope 17 is carried because running orbit changes, and caused pulling force, prevents garbage barrier net 16 from damaging；The shaft end of linked network axle 30 is set
There is change 32, can be rotated around linked network axle 30, the earrings set 33 that steel wire rope 17 is installed in change 32 deviates the center of change 32, works as traction
Chain is run to arc trajectory, and change 32 can produce bigger torque, is rotated more flexible so that steel wire rope 17 will not be because
Track, which changes, causes torsion.
Main guide rail is closed circular structure, is mainly used in providing guiding for linked network axle 30 and role-taking is on linked network axle 30
The deadweight for blocking water resistance and conduction chain；Flusher is mainly made up of water collection sheet 15, hydraulic giant 14, and it is arranged on pontoon bridge 2
On setting position, for rinsing the debris on garbage barrier net 16；Drainage is made up of water leg 13, water pump 12, blow-off pipe 34,
Water leg 13 is located at the lower section of water collection sheet 15, and for collecting, depositing sewage, water pump 12 and blow-off pipe 23 are used in water leg 13
Sewage discharge is to specified location.
The present invention under control of the control system, motor driving drive shaft, makes two the 5th drive chains through two-stage Chain conveyer
Wheel obtains power and motion simultaneously, and two articles of conduction chains of rotation driving of two the 5th drive sprockets are through three the 6th driven chains
Wheel, the 7th driven sprocket, the 8th driven sprocket are led installed in two in pontoon bridge circular flow on water delivery open channel width
The garbage barrier net drawn between chain will be along main guide rail circular flow.Garbage barrier net on chain under conduction chain, which is in, blocks dirty work
State, lifting state is in the garbage barrier net on cochain transition one end positioned at chain under conduction chain, on conduction chain cochain
Garbage barrier net piece the auto-flushing (debris after flushing is carried out by the flusher being fixed on pontoon bridge under control of the control system
And sewage deposit water leg, then voluntarily handled under control of the control system by the water pump in drainage and blow-off pipe), position
It is in down in the garbage barrier net on the downward chain transition other end of conduction chain cochain and is put into water state.Installed in longitudinally displaced two
Garbage barrier net piece between conduction chain, realizes cycle operation under motor, transmission device, chaindriven traction, it is free of discontinuities block it is dirty,
Decontamination.Dirt-lifting-flushing-decentralization circulation work entirely is blocked, is automatically performed by control system control, eliminates artificial decontamination
Operation, greatlys save operating cost.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
