When the foreign material that the current of arrow direction bring, when resting on the cantilevered folding face trashrack, the current conveyance capacity by this trashrack weakens, and produces bigger differential water pressures before and after making this trashrack.At this moment, pressure sensor sends signal, and by control electric loop and electrical equipment starting electric winch.After the electric winch starting, drive the downstream face of portable rack take, move to the top from its bottom along cantilevered folding face trashrack grizzly bar by wire rope.At this moment, foreign material move up under the pressure of the power of carrying of the rake teeth that passes grizzly bar and current.When foreign material move to the top of cantilevered folding face trashrack,, drive the raking arm and the rake teeth rotating certain angle thereof of rack take simultaneously because the break-in of track makes two sliding shoes certain angle that tilts simultaneously.Rake teeth is pushed to foreign material the top of cantilever grid when rotating, and when moving on it continues foreign material is pushed in the removing contamination bucket that collects in the dirty pond fully.
When portable rack take moves to the top of its track, device disconnects at the electric contact of the electric limit switch on track top, and stop electric winch running by the control electric loop, make portable rack take rely on it under focusing in its track smoothly, to slide to the track bottom, and engaging means are at the electric contact of the electric limit switch of track bottom.After limit switch is connected, start electric winch once more, rack take is moved up once more by the control electric loop.Relaxing when rack take glides owing to wire rope, when the raking arm that makes rack take is run into foreign material on the grizzly bar in the process that rake teeth glides, the energy rotating certain angle, and make in the rake teeth indentation grid crack, thereby guaranteed that rack take is not subjected to the influence of foreign material and downslide smoothly in the process that glides.When rack take moved up once more, wire rope relied on truckle, at first makes the rack take rotating certain angle, and begins to move up after making rake teeth stretch out the grid crack.
Treat that rack take is cleared up foreign material fully and pushed and remove contamination behind the bucket that the differential water pressures before and after the cantilevered folding face trashrack recovers normal.At this moment, pressure sensor sends signal, and by controlling the starting electric loop that electric loop and electrical equipment cut off electric winch, portable rack take is decommissioned after sliding to the track bottom under its deadweight, starts boom hoisting simultaneously.Boom hoisting starting back is at it automatically under the control of control electric loop, and will remove contamination to have struggled against by wire rope winches to the top of barrage, and with after grab after grid open, foreign material toppled over to remove contamination bucket.Before wire rope will be removed contamination the bucket lifting, at first drive scraper plate and rotate, and the foreign material that will rest on the cantilever are scraped into the bucket of removing contamination by rope.After foreign material are toppled over the bucket that to remove contamination, hang in the dirty pond of collection by being arranged on hook on the wire rope bucket of will removing contamination.At this moment and since in the bucket of removing contamination wire rope lax make the bucket of removing contamination before grab grid and hang fully by its deadweight, promptly be in the state of opening fully.When it fell to the inclined-plane of bottom, the dirty pond of collection, its bottom began to grab backward the grid closure along the inclined-plane, will collect foreign material residual in the dirty pond simultaneously and grab in the bucket of removing contamination.When the bucket of removing contamination drops down onto bottom, the dirty pond of collection fully, preceding grab grid with after to grab grid closed fully, the foreign material that will collect simultaneously in the dirty pond are all grabbed into the bucket of removing contamination, and begin to wait for the starting once more of electric winch.After the bucket of removing contamination falls into the dirty pond of collection fully, because hook is no longer stressed, thereby the buoyancy drive hook of ball float is turned an angle, and thoroughly break off relations with hanger.
When the bucket of removing contamination can not fall into collection during dirty pond fully because of stopping of foreign material, because of its hook breaks off relations, therefore will remove contamination after bucket slings and topple over the foreign material grabbing in the bucket of removing contamination by boom hoisting, once more it is hung in and collect dirty pond.Can not enter when bucket of removing contamination when big shape foreign material rest on cantilever top, when removing contamination the bucket lifting, foreign material are entrained in the middle of scraper plate and the dirt-carrying tooth by the elastic force of rope, and with its back removing of slinging.
Because ice slush that the reservoir water surface freezes before the barrage or floating ice slush and large-scale floating thing, discharge capacity to water inlet does not produce any influence, therefore breastwork keeps off face at its upstream with ice slush and large-scale floating thing, thereby the bucket that guaranteed to remove contamination successfully moves up and down at collection top, dirty pond.Could remove foreign material after bucket can only lift by crane owing to remove contamination, so this device can only operate discontinuously.But because the current that enter water inlet from reservoir can not bring continuous foreign material, so the remove contamination requirement of this device can satisfy current fully and from reservoir, enter water inlet the time.
When this device needs maintenance, then in the gate slot in its place ahead, put into Emergency Gate, overhaul after utilizing the hanger at its curb girder top that it is hung out then.Guide strip then can make it accurately in place when it was hung in.
Fig. 3 shows the 3rd embodiment of the present invention.
As shown in Figure 3: the top at the diversion runner 57 of pump chamber 25 is provided with dirt discharge groove 3, is provided with service bridge 39 at the top of dirt discharge groove 3, is placed with stop log gate 53 in the outlet of dirt discharge groove 3.On the bottom and the water cross section excessively between diversion runner 57 bottoms of dirt discharge groove 3 entrance, device has the grid frame that is made of back timber 7, bottom girder 17 and two corresponding mutually curb girders 18, be fixed with 60 at the upstream face of grid frame back timber 7 and be arranged in parallel each other, and the cantilevered of affixed respectively grizzly bar 14 formations after the brute force tension is rolled over the face trashrack between the other end of cantilever 26 that all has 25 millimeters spacings each other and cantilever 26 and bottom girder 17.
Because therefore the portable rack take of downstream face device of this cantilevered folding face trashrack can not in time be cleared up foreign material and the ice slush that current bring, thereby can bring very big pressure to trashrack grizzly bar 14.For preventing that grizzly bar and cantilever from destructive distortion taking place, in the center of two curb girders 17 of this trashrack downstream face, the transverse shape that is fixed with horizontal arrangement is wing wing crossbeam 31.Be connected with gripper shoe 32 respectively between wing crossbeam 31 and the grizzly bar 14.Wing crossbeam 31 and gripper shoe 32 have not only improved the support strength of grizzly bar, and to the drag effects minimum of current.After preventing that a large amount of foreign material from resting on the grizzly bar, the water level of trashrack upstream face is risen and the casual top of generation phenomenon, the flow passage side coping is provided with overflow weir 29 before trashrack.
The direction of pressing the arrow indication when current in runner is during by cantilevered folding face trashrack, and foreign material that brought by current and ice slush be attached on the grizzly bar, tangible water-head occurs before and after making cantilevered folding face trashrack.At this moment, after taking out the stop log gate of dirt discharge groove outlet, can foreign material and ice slush be salvaged to horizontal boom grid top by the rack take of artificial use special use, and foreign material are removed by dirt discharge groove, also can utilize special-purpose salvaging machinery, foreign material and ice slush be salvaged to horizontal boom grid top removed from dirt discharge groove.Though, this device when artificial or other when salvaging machinery and can not in time clear up foreign material and ice slush, can cause the clogging of runner or the blocking-up phenomenon of current, block dirty facility and compare with existing, this device can easily be removed foreign material, can discharge ice slush smoothly again.
