Description
Technical field
The present invention relates to the dirty equipment of collection of supply and drain water system, mainly is a kind of submerged level crawling sewage collection grating that is used for pumping plant, supply and drain water system irrigation channel.
Background technology
The dirty dirty device of rotary drum collection that adopts of irrigation channel collection such as existing urban water supply and sewerage, water intake pumping station generally is that rotary drum and mill are assembled into one, and dirt is held back and is brought to mill by the fixedly axle center rotation of rotary drum and pulverize.The rotary drum footprint of the dirty device of this collection is little, and inefficiency will enlarge footprint and have only the increasing roller diameter, and the overall volume of the dirty mill of collection is strengthened, and has increased manufacturing cost and installation, maintenance difficulty; The structure installation form that collects dirty rotary drum and mill and be one is restricted, and can not adapt to the needs of the installation occasion of various natural conditions; Have the dead angle in the side away from the dirty device of collection, solid dirt easily is trapped in the place, dead angle and can't brings to the mill pulverizing, can cause secondary pollution for a long time, and it is undesirable to collect dirty effect; The rotary drum fixed axis is provided with the water hole perpendicular to the axle center in the heart, and water hole rotates with the axle center, and water hole is little, and water flow is little, and dirt easily is trapped on the rotary drum barrier, and discharge capacity is poor, the dirty efficient of influence collection.
The disclosed a kind of diving pull-type dirt collecting grille of number of patent application CN200810124028.0, form by the traction astragal that parallel sleeve on the cylinder of vertical parallel placement more than two and adjacent two cylinders is equipped with more than at least one, it is simple in structure, easy for installation, adapt to the dirty demand of irrigation channel collection that area of passage does not wait.But this dirt collecting grille adopts rubber or steel wire traction circle, and traction circle itself or the elastic deformation that is hit or twined by dirt all can change and cross the water spacing between adjacent traction circle, and the dirty efficient of influence collection, service behaviour is reliably unstable, and result of use is not good.
Summary of the invention
The objective of the invention is for shortcoming such as overcome unreasonable structure, cost height that prior art exists, installation and maintenance are loaded down with trivial details, installation form is single, footprint is little, discharge capacity is poor, the dirty effect of collection is undesirable, and provide a kind of simple in structure, footprint big, no dead angle, discharge capacity is strong, the collection dirt is effective, adaptable submerged level crawling sewage collection grating is installed.
In order to achieve the above object, the present invention is by the following technical solutions: a kind of submerged level crawling sewage collection grating, mainly comprise grid framework, be located at reduction box and motor that the grid framework below links to each other, at interval quiet grid sheet more than is installed in the described grid framework, quiet grid sheet two ends are fixed on the grid framework; Be provided with an above eccentric shaft in the grid framework perpendicular to quiet grid sheet, the upper end of eccentric shaft is installed on the grid framework through bearing, the lower end of eccentric shaft connects reduction box through bearing, be with axle sleeve on the eccentric shaft, axle sleeve is provided with moving grid sheet more than, and every moving grid sheet is distributed between the adjacent two quiet grid sheets.
Further, described moving grid sheet is set on the axle sleeve or is flush-mounted in the axle sleeve surface, and moving grid sheet is trapezoidal or rectangle or circular arc, and moving grid sheet length is moved the width that the grid sheet width is not less than quiet grid sheet less than the length of quiet grid sheet.
The present invention drives eccentric shaft by reduction box, the moving grid sheet of eccentric shaft drive installation on the eccentric shaft axle sleeve made horizontal reciprocating movement along the circle of eccentric shaft revolution direction, and the movement travel of moving grid sheet is big, and the tractive force of comparing rotary drum and its generation of traction circle is bigger, collection is dirty effective, collects dirty efficient height; This dirt collecting grille forms a plane and blocks dirty structure, framework can be according to the structure design of dam embankment, can closely contact with the dam embankment, no dead angle, can adopt single group or organize grid and any matched combined use of mill more, it is big to increase the dirty area of collection, and the channel that adapts to different area of passages is installed and used; Cross water by the gap between moving grid sheet and the quiet grid sheet, crossing water space stablizes indeformable, overcome and draw the shortcoming of enclosing the dirty effect of water space deformation effect collection in the public technology, and the sound grid sheet is thinner, is difficult for twining dirt, and water flow is big, hydraulic pressure divides difference little between dirt collecting grille and the mill, moving grid sheet can advance dirt reposefully to mill level wriggling, dirt is difficult for piling up, and it is strong to collect dirty ability; This apparatus structure is simple, and is convenient for installation and maintenance, and cost is low, collects dirty efficient height, and working stability is reliable, satisfies the demand of various occasions.
