when the negative weight block is combined with the water bucket, the negative weight block is contacted with the upper edge of the water bucket.

The working principle and the process are as follows:

when the bucket is in work, under a normal state, the gravity of the load block is larger than that of the bucket, the bucket is lifted, and the load block is contacted with the upper edge of the bucket. Accumulated water flows to a geosyncline and flows into a drainage channel through a left ejector rod and a right ejector rod and is collected in a bucket, sundries such as leaves, plastic bags and stones are blocked by the left ejector rod and the right ejector rod and are retained on the left ejector rod and the right ejector rod, when the integral gravity of the accumulated water and the bucket is greater than that of a negative weight block, the bucket moves downwards, the negative weight block moves upwards, a left chain drives a left chain wheel to rotate anticlockwise, the left chain wheel drives a left turning roller to rotate anticlockwise, the left turning roller drives the left ejector rod to stir the sundries to the left side to enable the sundries to fall into a left collection pit, a right chain drives a right chain wheel to rotate clockwise, the right turning roller drives a right ejector rod to stir the sundries to the right side to enable the sundries to fall into a right collection pit, further, sundries remaining on the left ejector rod and the right ejector rod are avoided from being blocked, and cleaning is automatically completed, manual cleaning is not needed, and labor and cost are greatly saved. When the bucket touches the bottom, the bucket is in an inverted cone shell shape, the tip of the bottom of the bucket contacts the ground, the bucket topples to one side due to instability, the wall of the bucket is parallel to the ground at the bottom of the drainage channel after toppling, and accumulated water flows out instantly. At the moment, no water is accumulated in the bucket, the weight block pulls the bucket to move upwards and reset, and then the process is repeated until no water is accumulated. Because the left ejector pins of the adjacent left-turning rollers are arranged in a staggered manner, and the right ejector pins of the adjacent right-turning rollers are arranged in a staggered manner, sundries are remained at the upper ends of the ejector pins, so that not only is the sundries prevented from slipping, but also the sundries cannot enter between the left-turning rollers or the right-turning rollers. The volume of collecting the pit can set up as required, can clear up once for a long time, reduces the amount of labour.

The left ejector pin of the rightmost end left-hand roller and the right ejector pin of the leftmost end right-hand roller are arranged in a staggered mode, so that the rotation of the left-hand roller can not be influenced, meanwhile, a gap between the left toggle mechanism and the right toggle mechanism can be avoided, and sundries are prevented from entering the left-hand roller.

The small plates are vertically fixed on the inner walls of the left end and the two sides of the middle position of the frame, the springs are fixed on the small plates, the upper ends of the springs are fixed with U-shaped frames, left top wheels are installed in the U-shaped frames, and the left top wheels on the same side jack up corresponding left chains to enable the left chains to be separated from the left chain wheel; the small plates are vertically fixed on the inner walls of the right end and two sides of the middle position of the frame, the springs are fixed on the small plates, the upper ends of the springs are fixed with U-shaped frames, right top wheels are installed in the U-shaped frames, and the right top wheels on the same side jack up corresponding right chains to enable the right chains to be separated from the right chain wheel; the left top wheel and the right top wheel are both in a pulley shape. Under the normal state, no water exists in the bucket, the whole weight of the bucket is light, the left top wheel and the right top wheel are jacked up by the elasticity of the spring, and the left top wheel and the right top wheel respectively jack up the left chain and the right chain. When accumulated water flows into the bucket, the bucket is integrally heavy, the spring is pressed, the left chain can be meshed with the left chain wheel again, the right chain can be meshed with the right chain wheel again, the bucket moves downwards and is toppled over when touching the bottom, water flow is exhausted, the left chain and the right chain are jacked up again by the spring elasticity at the moment, the bucket is pulled by the load block to move upwards and reset, the left rotating roller and the right rotating roller cannot be rotated when the chain is reset, the reset of sundries on the left ejector rod and the right ejector rod is avoided, and the unidirectional rotation of the left rotating roller and the right rotating roller is ensured.

The left top wheel and the right top wheel which are positioned in the middle of the frame are coaxially arranged, and then the left chain and the right chain are arranged in a staggered mode. The left ejector pin of the rightmost end left-hand roller and the right ejector pin of the leftmost end right-hand roller are arranged in a staggered mode, the distance between the corresponding left chain wheel and the right chain wheel is very limited, and the left top wheel and the right top wheel are coaxially arranged to ensure that the left top wheel and the right top wheel have large enough sizes to ensure reliable operation of the chain.

The negative weight block is made of iron, and a magnet is fixed on the upper edge of the bucket at a position corresponding to the negative weight block. Heavy burden piece and magnet actuation under normal condition, only when the cask with the gravity of the ponding in it is greater than heavy burden piece gravity and when the magnetic attraction of heavy burden piece and magnet, heavy burden piece and magnet quickly separating, the cask falls fast, and then drives the roller that turns left and the roller that turns right fast rotatory, left ejector pin and right ejector pin have enough centrifugal force like this throw away debris to collecting in the pit, have on avoiding left ejector pin and the right ejector pin to remain, the more thorough of automatically cleaning. When the negative weight block is reset, the negative weight block and the magnet are attracted again.

The magnet is spherical. The accumulated water is difficult to avoid the impurities containing iron, which can be adsorbed on the surface of the magnet, so that the adsorption effect of the magnet and the weight bearing block is poor. The magnet is globular, and the iron impurity can be along the spherical surface landing of magnet, avoids influencing the absorption of magnet and heavy burden piece.

The upper parts of the collecting pits and the drainage channel are provided with communicating grooves. There is ponding inflow sometimes in collecting the pit, and the intercommunication groove can be so that the ponding that overflows flows into drainage channel from the intercommunication groove, avoids collecting the debris in the pit and is washed away by ponding.

The collecting pit is internally matched with a collecting cage. Directly when the pit is collected in the clearance mention can with collecting the cage, it is very convenient to clear up, alleviates sanitationman's work load, improves work efficiency.

The articulated shaft of cask and left chain and the articulated shaft of cask and right chain all are perpendicular with the dead axle. The bucket is the back taper shell shape, and its incline direction is random, and through above-mentioned setting, the bucket just can incline forward or backward when touching the end, and left chain and right chain just need not the bending deformation during the slope, not only makes the bucket can incline completely, and hydroenergy drains to the greatest extent, avoids the chain to buckle moreover and breaks away from with the sprocket.

Compared with the prior art, the invention has the beneficial effects that:

according to the rotary roller separately-shifting type self-cleaning anti-blocking municipal drainage device, when accumulated water and the overall gravity of a water bucket are larger than the gravity of the load block, the water bucket moves downwards, the load block moves upwards, the left chain drives the left chain wheel to rotate anticlockwise, the left chain wheel drives the left rotary roller to rotate anticlockwise, the left rotary roller drives the left ejector rod to shift sundries to the left side, the sundries fall into the left collection pit, the right chain drives the right chain wheel to rotate clockwise, the right chain wheel drives the right rotary roller to rotate clockwise, the right rotary roller drives the right ejector rod to shift the sundries to the right side, the sundries fall into the right collection pit, the sundries are prevented from remaining on the left ejector rod and the right ejector rod, blockage is avoided, cleaning is automatically completed, manual cleaning is not needed, and manpower and cost are greatly saved. When the bucket touches the bottom, the bucket is in an inverted cone shell shape, the tip of the bottom of the bucket contacts the ground, the bucket topples to one side due to instability, the wall of the bucket is parallel to the ground at the bottom of the drainage channel after toppling, and accumulated water flows out instantly. At the moment, no water is accumulated in the bucket, the weight block pulls the bucket to move upwards and reset, and then the process is repeated until no water is accumulated. Because the left ejector pins of the adjacent left-turning rollers are arranged in a staggered manner, and the right ejector pins of the adjacent right-turning rollers are arranged in a staggered manner, sundries are remained at the upper ends of the ejector pins, so that not only is the sundries prevented from slipping, but also the sundries cannot enter between the left-turning rollers or the right-turning rollers. The volume of collecting the pit can set up as required, can clear up once for a long time, reduces the amount of labour. Can accomplish the clearance of water inlet automatically, avoid rubbish and leaf to plug up the water inlet, guarantee that ponding can in time drain away, can automatic collection leaf and rubbish, alleviate sanitationman's burden, effectively prevent urban waterlogging simultaneously.
