Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.
Known in conjunction with Fig. 1-3: water wheels rotary grate 1 described in the utility model is arranged on the overflow weir 21 of storm-water system 20, wherein, storm-water system 20 specifically comprises water inlet pipe 22, rising pipe 23 and leads to the emergency episode pipe 24 of settling pond.
When rainfall occurs, rainwater enters from water inlet pipe 22, and the water level in storm-water system 20 constantly rises, and wherein, the rainwater that has little time directly to enter settling pond enters water body through after being arranged on the screening of the water wheels rotary grate on overflow weir 21.
Wherein, water wheels rotary grate 1 is installed on the upper limb of overflow weir 21.Concretely, the framework 19 of water wheels rotary grate 1 is fixed on overflow weir, and water wheels 9 are installed lower than the position of overflow weir end face in the bottom of framework 19, and water wheels 9 drive crank driving device 8 to move by chain drive.
Wherein, chain drive is connected by chain the first runner and the second runner form; The first runner is arranged in the rotating shaft of described water wheels 9, drives rotation by water wheels 9, then rotates by chain-driving the second runner; The second runner is installed on the top of framework 19, and is connected with crank driving device 8.
Wherein, crank driving device 8 is installed in the rotating shaft of the second runner, and two ends are separately fixed on the second runner, and its two-end-point can be moved in a circle around the rotating shaft of the second runner.
Fishback 4 and loading plate 5 have formed a stripper.Wherein, loading plate 5 is arranged on the other end of driving stem 6, and the broach of fishback 4 be in one line be arranged on loading plate 5 above.
Grizzly bar 2 one end are arranged on the top of framework 19, and the other end is fixed on the inwall of overflow weir 21, forms one grid, for the pollutent of screening and filtering water.Wherein, the grizzly bar gap 3 between grizzly bar 2 is corresponding with the broach of fishback 4, and broach can insert in grizzly bar gap 3 just, thereby coordinates fishback 4 to work, and combing is wrapped in the residual contaminants on grizzly bar 2.
As preferred scheme, in order to allow water wheels high-efficient operation, can one cover be installed at overflow weir 21 tops, its can be further to the end face of external expansion overflow weir 21, object is guiding water (flow) direction, allows water slug how as far as possible on the flabellum of water wheels, improves the efficiency of conversion of power.
Below in conjunction with Fig. 4 and Fig. 5, the principle of work of explanation water wheels rotary grate.
In the time that water level exceedes the height of overflow weir 21, the current that overflow impact on the flabellum of water wheels 9 by the guiding of cover, and water wheels 9 start to rotate; After rotating, water wheels 9 drive crank driving device 8 to rotate by chain gearing, crank driving device 8 drives driving stem 6 under the cooperation of steady bearing 7, along continuous straight runs moves reciprocatingly, in vertical direction, select, now, 4 of fishbacks that are arranged on as seen driving stem 6 the other ends start to carry out the work of peeling off pollutent for grizzly bar 2 combings.Wherein, what Fig. 4 showed is that fishback 4 inserts behind grizzly bar gap 3, following current process from top to bottom, what Fig. 5 showed is that fishback 4 detaches behind grizzly bar gap 3, adverse current process from the bottom to top, this process also can reboot back the pollutent of going out grizzly bar, and it is peeled off grizzly bar 2 and automatically falls into collection space the most at last.
Finally, crank driving device of the present utility model is to adopt water wheels to drive, and this is optimal selection scheme of the present utility model, and as an alternative solution, crank driving device also can be driven by power-actuated motor.
The above-described preferred embodiment of utilizing describes the utility model in detail, and unrestricted scope of the present utility model.Those skilled in the art can, by reading after the utility model, make trickle change and adjustment, and the main idea of the present utility model of will can yet be regarded as place, does not also depart from spirit and scope of the present utility model.
