Description

The device of automatically removing sewage in grid of water intake of river channel

Technical field:

The utility model relates to a kind of in feedwater, water conservancy, water power, removes the device of the automatically removing sewage in grid of water intake of river channel that the dirt on its intake place filtering grid uses, and belongs to intake filtering grid dirt removal technical field.

Background technology:

At feedwater, water conservancy, mistake drift angle water power water intaking oral area,, water withdrawal more shallow when the river accounts for discharge of river amount ratio when big, adopts the mode (general height of dam is lower than 3m) of barrage weir usually, the localized raised river level, increase the local depth of water, to guarantee enough water draw rates.In order to guarantee to fetch water water quality and make full use of head, the position of the present oral area of all will fetching water is arranged on relatively away from project subject zone partly, such as the zone away from power supplies such as water treatment works, main irrigation district, power station, traffic convenience, the position of the oral area of fetching water sometimes and project subject part reach tens of kilometers apart.Floating thing and big particle enter the diversion pipe duct in the river in order to avoid, the grid of having to again be provided with at the intake place, with interception floating thing and big dirts such as particle,, then must often remove the dirt of grid interception for eliminating the influence of the accumulation of dirt before grid to water diversion.At present, in the prior art for adopting power-actuated decontamination apparatus near the removing of the sewage in grid of major project or adopting the artificial cleaning of regularly making an inspection tour, but remove for sewage in grid away from the intake place of major project, then above dual mode all is difficult to realize, one during away from major project, have inconvenient traffic under most of situation, the manual patrol cleaning can't realize; The two is as adopting electric device, because away from the major project zone, therefore all there is very big difficulty in electricity consumption point on the reliability of engineering cost and operational management.Therefore at present running into analogue in engineering utilizes existing technology to solve all to have many problems.

Summary of the invention:

The purpose of this utility model is: provide a kind of investment cost and running cost all cheap, do not have the device of power consumption, unmanned, automatically removing sewage in grid of water intake of river channel that functional reliability is high simultaneously, to overcome the deficiencies in the prior art.

The utility model is achieved in that it comprises the grid (1) that intake is preceding, on the other barrage of grid (1), be provided with the gutter (2) that a river can flow through and bottom surface has difference of height, delivery port place in gutter (2) lower end is provided with a bar spoke formula tumbler (4), pulpboard (3) is housed on bar spoke formula tumbler (4), at the preceding rotating mechanism (6) that is equipped with of grid (1), the skimming rake (5) that can contact with the surface of grid (1) is installed on rotating mechanism (6), driving gear (7) is housed in the rotating shaft of bar spoke formula tumbler (4), driven gear (8) is housed in the rotating shaft of rotating mechanism (6), between driving gear (7) and driven gear (8), is engaged with transition gear (9); Be provided with the pushing off the slag cover plate (10) that intake top can be covered in the rear end, top of grid (1); In the other slag rake skimmer device (11) that is provided with of the rotating mechanism (6) that skimming rake (5) is installed; Grid (1) is a circular shape.

Owing to adopted technique scheme, the utility model utilizes the skimming of nature hydro powered to harrow the dirt of removing on the grid, unregulated power consumes, do not need the personnel marquis of keeping on duty, therefore, the utility model compared with prior art, that the utility model not only has is simple for structure, can save engineering and operating cost, functional reliability height, advantage that maintenance workload is little, thereby but also has the infield that is suitable for various harshnesses, and can reduce advantage such as manpower quota's minimizing expense expenditure.

Operating principle of the present utility model: it utilizes the head of the barrage weir formation that need be provided with because of water intaking, make the river remaining flow penetrated preferably gutter of fetching water, when current have the gutter of difference of height by the bottom surface, its potential energy (potential energy) is converted into kinetic energy (flow velocity increase) and promotes the pulpboard motion, thereby drive the driving gear mechanical rotation by its rotating shaft, and provide rotational power for the skimming rake by driven gear; During the utility model work, its intake water inlet at first supplies user of subordinate or process water by its diversion pipe duct behind the grid interception dirt by circular shape, and the rotation of the dirt of grid interception by the skimming rake is removed, skimming rake rake except that dirt drop on the pushing off the slag cover plate and and skim the system by slag rake skimmer device.Because the rotating speed that the skimming rake requires is very low, even can be lower than per hour 1～2 commentaries on classics, running resistance is very little again, so current can be enough to provide power; Operating between flood period of skimming rake, floating thing and particulate dirt are more, and running resistance increases, and the skimming amount increases, and this moment, the flow by gutter increased naturally, correspondingly provides bigger operation power, makes skimming harrow faster rotational speed; Operating at ordinary times of opposite skimming rake, floating thing and particulate dirt are less, running resistance reduces, the skimming amount reduces, the flow of gutter is also corresponding to be reduced near minimum dependable flow and lead to this moment, the power that corresponding hydraulic drive apparatus provides diminishes, and skimming rake rotating speed slows down, and reaches the purpose of automatic adjusting skimming rake rotating speed.
