the collection pit is positioned at the output end of the conveying rope.

The working principle and the process are as follows:

during operation, the condition such as rainstorm leads to ponding, and ponding flows to geosyncline department, and ponding flows in the drainage pit through the conveying rope and gathers in the cask, and debris such as leaf, plastic bag, stone are blockked by the conveying rope. Along with ponding constantly gathers in the cask, the whole weight of cask constantly increases, and when the gravity of cask was greater than the elasticity of torsional spring, the cask descends, and the stay cord drives the winding roller rotatory, and the winding roller drives the conveying rope and rotates, and debris on the conveying rope move to the collection hole along with the conveying rope, and when reacing the commentaries roller of right-hand member, debris fall to in the collection hole. When the bucket is in contact with the bottom, the ejector rod is jacked up, and accumulated water flows out of the through hole and flows into the main drainage channel along the branch channel. After the accumulated water flows away, the whole weight of the bucket is reduced, the gravity of the bucket is smaller than the elasticity of the torsion spring, the rotating roller rapidly rotates reversely under the elasticity of the torsion spring, and the bucket resets. Under the condition that has ponding, the above-mentioned process of this device continuous repetition can collect debris at the in-process of drainage, again can automatic clearance debris, avoids debris jam grid, need not artifical clearance, very big saving manpower and cost. Sundries can be collected in the collection pit, the volume of the collection pit can be set according to needs, the sundries can be cleaned for a long time, and the labor amount is reduced.

The brush is fixed to the conveying rope output end, inclines to the collection pit, and the brush left end is close to the conveying rope. The leaves can be attached to the conveying rope after being soaked, the leaves can be brushed down through the hairbrush, meanwhile, the hairbrush can also play a role of a sliding groove, and sundries can slide into the collecting pit from the hairbrush.

The upper ends of the collecting pits and the water drainage pits are communicated through the communicating grooves, and the communicating grooves are plugged by the parts of the brushes extending into the collecting pits. It has ponding entering to be difficult to avoid in the collection hole to can float impurity such as leaf, plastic bag on the ponding surface of water, the brush plays the filtering action, and the ponding that overflows can flow in the water drainage hole through the intercommunication groove, thereby impurity is blockked by the brush and stays in collecting the hole.

The position of the rotary roller corresponding to the conveying rope is circumferentially provided with a limiting groove, and the conveying rope is matched in the limiting groove. The spacing groove can avoid the conveying rope skew.

The equidistance sets up gluey post on the conveyer rope medial surface, the position that corresponds gluey post on changeing the roller sets up the counter bore, the counter bore cooperates with gluey post, gluey post interval on all conveyer ropes is the same, the gluey post that corresponds the position on all conveyer ropes is on same straight line, this straight line is the acute angle with the angle that comb plate formed, at the fixed comb plate in geosyncline, the comb plate both ends are fixed on the geosyncline lateral wall, every conveyer rope all is located between the broach that corresponds on the comb plate, inlay the dress and collect the box on the pit lateral wall, it extrudes the side to collect the box to be located gluey post. Occasionally, flaky stones leak from the upper layer of conveying ropes but fall on the lower layer of conveying ropes, and the stones are squeezed between the conveying ropes and the rotating roller along with the movement of the conveying ropes, so that damage is caused. The glue columns and the comb plate are arranged, the glue columns drive the stones to move towards the comb plate, when the stones are blocked by the comb plate, because the glue columns at the corresponding positions on all the conveying ropes are on the same straight line, the angle formed by the straight line and the comb plate is an acute angle, the distance from the glue columns at the corresponding positions to the comb plate is gradually increased from top to bottom, the glue columns play a role in guiding, and thus the stones are forced to move downwards and finally fall into the collecting box. The rubber column is the rubber material, has certain elasticity, and when the stone shape was irregular and the card was between rubber column and comb plate, the rubber column can take place deformation and collapse stone, and the stone falls on the conveyer rope again, and the position also just changes, makes things convenient for hou mian rubber column to promote the stone and gets into and collect the box.

The iron sheet has a limiting effect, and the bucket stops rising when the magnet is contacted with the iron sheet. When the integral gravity of the bucket is greater than the sum of the elastic force of the torsion spring and the magnetic attraction force of the magnet, the magnet is separated from the iron sheet instantly, the bucket falls down quickly, the conveying rope drives sundries to rotate quickly, the conveying rope stops immediately when the bucket touches the bottom, and the sundries are thrown into the collection pit due to inertia. Thus the conveying rope is cleaned more thoroughly.

The magnet is spherical. It is inevitable to have the impurity of iron-bearing in ponding, and it can adsorb on the magnet surface, leads to magnet and iron sheet adsorption effect to worsen. Magnet is globular, and the iron impurity can avoid influencing the absorption of magnet and iron sheet along the spherical surface landing of magnet.
