A kind of precipitation pool structure for river sewage processing, as shown in Figure 1 and Figure 2, including sedimentation basin 1, in sedimentation basin 1
Bottom is equipped with drive seat 2 and mud-scraping apparatus 3, and starting drive seat 2 can drive mud-scraping apparatus 3 to start clearly in 1 bottom of sedimentation basin
Mud is managed, is additionally provided with mud mouth 4 in 1 bottom of sedimentation basin, mud mouth 4 is arranged in the edge of sedimentation basin 1, and mud can scrape mud
Gradually toward moving at mud mouth 4 under the action of device 3, while being equipped in the side of sedimentation basin 1 and taking out mud device 5, take out mud device 5 with
Mud mouth 4 is connected to, by can extract the mud at mud mouth 4 outside sedimentation basin 1 out under the action of pumping mud device 5, so
Cycle operation clears up the mud being deposited in sedimentation basin 1.
As shown in Fig. 2, Fig. 3 and Fig. 4, mud-scraping apparatus 3 includes two groups of cleaning shoes 6, and every group of cleaning shoe 6 is provided with two,
Cleaning shoe 6 is vertical two-by-two and is mutually permanently connected, and the rotation center of cleaning shoe 6 is in 1 center of sedimentation basin and bottom surface and sedimentation basin 1
Bottom abuts, and arcwall face 26 is equipped on 6 side wall of cleaning shoe, and the setting of arcwall face 26 can enable cleaning shoe 6 that can preferably strike off
The mud being deposited under sedimentation basin 1 is fixed with main swing arm 7, main swing arm 7 and 1 lower rotation of sedimentation basin at 6 center of cleaning shoe
Connection is fixed with master bevel gear 8 in 7 bottom end of main swing arm, and drive seat 2 includes motor 9, and output bevel gear wheel 10 is equipped on motor 9,
Output bevel gear wheel 10 is intermeshed with master bevel gear 8, and when opening motor 9, the rotation of output bevel gear wheel 10 can drive master bevel gear
8 rotate together, so that cleaning shoe 6 rotates the cleaning for carrying out mud in 1 bottom of sedimentation basin.
One group of cleaning shoe 6 is equipped with push plate 11 wherein, on one piece of cleaning shoe there are two the quantity settings of push plate 11, is scraping
Mud plate 6 is equipped with the guide rod 12 of strip ring seal, and push plate 11 is connected on guide rod 12 and is slidably connected with it, the setting of guide rod 12
Push plate 11 is guide around the sliding of cleaning shoe 6 surrounding, the side wall of push plate 11 is abutted with 6 side wall of cleaning shoe and bottom surface and sedimentation basin 1
Bottom surface abuts, and the universal driving shaft 15 being rotatablely connected with it is in addition equipped at 6 center of cleaning shoe, connection is fixed in the bottom end of universal driving shaft 15
Dynamic bevel gear 17, is equipped with driving member 18 between linkage bevel gear 17 and output bevel gear wheel 10, and driving member 18 includes two cone teeth
Wheel, driving member 18 are engaged with output bevel gear wheel 10 and linkage bevel gear 17 simultaneously, therefore when unlatching motor 9, output bevel gear wheel 10
Rotation can drive simultaneously linkage bevel gear 17 rotate together, while on cleaning shoe 6 be equipped with linkage mechanism, linkage mechanism with connection
Moving axis 15 connects and linkage push plate 11 is slided on cleaning shoe 6, and the setting of guide rod 12 guides push plate 11 by linkage mechanism
Cycle is slided around 6 outer rim of cleaning shoe under the action of thrust, and the side wall of push plate 11 is abutted with 6 side wall of cleaning shoe always when sliding,
Therefore while cleaning shoe 6 rotates cleaning mud, assist to push toward 1 edge of sedimentation basin positioned at the mud at 1 center of sedimentation basin, from
And promote the efficiency of cleaning mud.
It is fixed with linkage gear 16 on 15 top of universal driving shaft, linkage mechanism includes two fixed gears 13 and chain 14,
In two fixed gears 13 be rotatably connected on respectively on cleaning shoe 6, position is in cleaning shoe 6 on one end of 1 outer rim of sedimentation basin,
Chain 14 and two fixed gears 13 are intermeshed, and linkage gear 16 is meshed with chain 14, is uniformly arranged in the bottom surface of chain 14
There are multiple pushing blocks 19 for pushing push plate 11 to be slided on cleaning shoe 6, pushing block 19 to be abutted with push plate 11, meeting when chain 14 moves
It is set to be slided on cleaning shoe 6 promotion of push plate 11 under the action of pushing block 19, when opening motor 9, output bevel gear wheel 10 turns
It is dynamic that linkage bevel gear 17 can be driven to rotate together simultaneously, and then chain 14 is driven to be moved on two fixed gears 13, linkage cone tooth
For wheel 17 after driving member 18 is connect with output bevel gear wheel 10, the direction of rotation of universal driving shaft 15 can be with the direction of rotation of main swing arm 7
On the contrary, therefore cleaning shoe 6 rotate cleaning mud when, push plate 11 can cleaning shoe 6 scrape mud working face from the center of sedimentation basin 1 to
It moves at edge.
As shown in Fig. 2, in 6 symmetrical centre of cleaning shoe, there is the pushing blocks 19 on chain 14, and push plate 11 can not be pushed to turn
Blind area 25, when gradually sliding into blind area 25 under guiding of the push plate 11 in guide rod 12, push plate 11 can with pushing block 19 progressively disengage and
The corner of cleaning shoe 6 is rested on, therefore the two is fixedly linked equipped with steel cable 20 in same group of push plate 11, while steel cable 20
It is in closed state around 6 outer rim one of cleaning shoe circle, the wire casing 21 for being absorbed in storage for steel cable 20, steel cable is in addition provided on cleaning shoe 6
20 are slidably connected with 21 level of wire casing, when push plate 11, which slides into blind area 25, to be detached from pushing block 19, with other one piece of push plate of group
11 still in the stroke pushed by pushing block 19 within, therefore the push plate 11 that is pushed can pull and pushing block 19 under the action of steel cable 20
The push plate 11 of disengaging is slided together, after the push plate 19 drawn slips over blind area 25 push plate 11 can be abutted again with pushing block 19, and
And continue to push mud to sedimentation basin 1 edge from 25 direction of blind area.
4 quantity of mud mouth in 1 bottom of sedimentation basin has 4 and is uniformly arranged, and can be made by the way that multiple mud mouths 4 are arranged
The speed that mud skids off sedimentation basin 1 is accelerated, to promote the whole cleaning efficiency of sedimentation basin 1.
As shown in Figure 4, Figure 5, storage mud groove 22, when mud is excessive, the silt that is pushed by cleaning shoe 6 are equipped at mud mouth 4
Mud can be fallen directly into from mud mouth 4 into storage mud groove 22, and mud is avoided to be pulled at mud mouth 4 because accumulation excessively can not be timely
The case where being pulled away and scraping off mud mouth 4 by the rotation of cleaning shoe 6 again occurs.It includes slush pump 23 to take out mud device 5, in storage mud
22 bottom of slot is equipped with extraction mud pipe 24, and extraction mud pipe 24 mutually converges to be connect with slush pump 23 afterwards, can be incited somebody to action by operating slush pump 23
Store up the extraction out of sedimentation basin 1 of the mud in mud groove 22.
Specific implementation process；Start motor 9 and slush pump 23 works, output bevel gear wheel 10 starts to rotate at this time, rotation
While drive master bevel gear 8 rotate together so that cleaning shoe 61 bottom of sedimentation basin rotate carry out mud cleaning, it is defeated
While going out the drive rotation of master bevel gear 8 of bevel gear 10, linkage bevel gear 17 is driven to rotate together also through driving member 18, in turn
It drives chain 14 to be moved on two fixed gears 13, makes it in guide rod 12 promotion of push plate 11 by pushing block 19 when chain 14 moves
Guiding under cycle slided around 6 outer rim of cleaning shoe, by the mud in 1 center of sedimentation basin toward 1 edge of sedimentation basin in sliding process
It pushes, it is heavy that the mud fallen to from storage mud groove 22 from mud mouth 4 can be retracted under the action of slush pump 23 by extraction mud pipe 24
Outside shallow lake pond 1.
