Description
Technical field
The present invention relates to a kind of convertible dirt-blocking dirt-cleaning grid, belong to water environment technical field.
Background technology
Trashrack is made up of frame, diaphragm and grizzly bar, is bearing on concrete pier wall, generally manufactures with steel.Interval of grid strip is depending on dirt size, how many and utilization requirement.The interval of grid strip in power station depends on hydraulic turbine model and size, is as the criterion to ensure can not be stuck in water turbine overflowing component by the dirt of trashrack.Sluicing tunnel and spilled water hole generally do not establish trashrack, and as footpath, hole or aperture are little, and dead-wood is more when needing to arrange, and interval of grid strip should strengthen.
Trashrack load, except deadweight, mainly after dirt blocking, due to the water ballast(ing) that water-head is formed before and after grid, generally considers by 2 ~ 4m head.The grid face size of trashrack was decided by grid current amount and allowed grid current speed.For reducing head loss and being convenient to remove contamination, General Requirements is crossed grid current speed and is not more than about 1.0m/s.Trashrack can be made and fixing maybe can to lift by crane.
Trashrack can be arranged to linear or in the plane in the fold-line-shaped of semicircle, facade can be upright or tilts, according to water-borne dirt character, how many, use and to require and the mode of removing contamination determines.The water inlet of the power station at dam toe that head is higher is conventional upright semicircle; The multiplex linear of intake gate, hydraulic tunnel, aqueduct.
The trashrack height of deep type water inlet is relevant with mode of removing contamination with reservoir level.For what do not need often to remove contamination, its crest level can a little more than flood control; Need often to remove contamination, then should higher than the peak level needing remove contamination.Highly larger trashrack, can make a few joint, and the size often saved can be determined according to crane capacity.
At present, trashrack is mainly used in tackling the pollutant that power station and pumping station etc. send drainage works water inlet, as: branch, household garbage, pasture and water etc., prevent floating thing and creep material from entering pumping plant, guarantee the safe operation of pumping plant, reach better economic benefit, domestic many enterprises, because causing termination of pumping without trashrack or because trashrack structure design is not suitable for environment, damage pump configuration, or cause pump to corrode because dirt blocks, unit vibration, very harmful.
Domestic power plant unit is increasing, unit water requirement also increases more, and intake design increases more, and its supporting trashrack hierarchy structure requires also to increase, traditional trashrack is heavier and girder easily produces distortion more has victor to rupture, and there is very large potential safety hazard.User has strong complaints.So the trashrack of development of new formula, equipment performance is stablized, and meets the active demand in market.
The traditional trashrack used in China river course, reservoir, channel, is mostly fixed frame grid structure, is made up of frame, diaphragm and grizzly bar, can tackle the solid suspension in river course.
The drawback of tradition trashrack is that suspension removes problem, and traditional trashrack is fixed on both sides, riverbank usually, and during operation, suspended contaminant is easily suspended on above trashrack, is difficult to cleaning in water.In addition, utilize electric device to carry out the trashrack of Automatic clearance suspension in addition, suspension can be utilized the similar devices such as conveyer belt be sent to dustbin, the suspension solving traditional trashrack removes problem, but electronic trashrack uses the energy, installation and maintenance difficulty is large, and cost is high.Therefore, research and develop and a kind ofly not only can tackle suspended contaminant but also be convenient to the dirt-blocking dirt-cleaning grid cleared up, its cost is low, and does not need the device of additional energy source to be problem demanding prompt solution.
Application number is: the application for a patent for invention of 201210147035.9 discloses a kind of movable trash rack, make the fence that arranges in river course with block dirt or flood passage need carry out switch, effectively can block dirt, not affect again navigation and flood passage.But the trashrack of said structure needs manually to open or close trashrack, and it is more to there is structure member, the defect that volume is larger.
Application number is: the patent application of 201210584851.6, it discloses the cable-styled trashrack of a kind of automatic pollutant removal, it is characterized in that many single Suo Binglie, be combined into cable-styled trashrack, be arranged on power drum by its upper end, lower end makes cable-styled trashrack meet dirty face by reverse wheel to move upward. and centre has guide-localization to take turns and multiple locating wheel blocks dirty about Suo Jinhang locate cable-styled.Simultaneously equip decontamination clip blocking on dirty rope, block in dirty rope rotation process and automatically clear up by decontamination clip the dirt sticked on trashrack timely.But, the complex structure of the trashrack of this kind of structure, and or need to block under driving wheel drives dirty rope meet dirty towards on run, make dirt depart from the water surface, intelligence degree is not high.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provide a kind of and tackle suspension and the trashrack of intelligence removing dirt, this trashrack is without the need to extra electric power, the device being convenient to pollutant removing.
Concrete technical scheme of the present invention is:
A kind of convertible dirt-blocking dirt-cleaning grid, comprise framework below, frame sides, framework top, trashrack bar, rolling bearing, two ends, described framework top are fixed on rolling bearing inner ring, housing washer is fixed on support, framework below, two frame sides and framework top be composed of a fixed connection frame construction, is provided with trashrack bar in the middle of frame construction; Also comprise pressure sensor, rotary drive mechanism and controller, the thrust size that described pressure sensor is formed trashrack bar for detecting current, and the thrust signal of detection is transferred to described controller, controller and described rotary drive mechanism control connection, two ends, described framework top are stretched out the inner ring of described bearing and are connected with the axis of rotation of described rotary drive mechanism, described blowpit is arranged on the back side of described trashrack bar, is fixedly connected on support by fixed mount.
The reductor that described rotary drive mechanism comprises electric rotating machine, is connected with electric rotating machine output shaft, the output shaft of reductor is connected with the two ends of described framework top.
Described framework below, frame sides, framework top be pipe, and framework top external diameter is less than the internal diameter of rolling bearing inner ring.
Described trashrack body is provided with and prevents suspension anti-skid structure along the landing of trashrack bar under self gravitation effect.
Described anti-skid structure be fixed on framework below on rake teeth.
Compared with prior art, its beneficial effect is in the present invention:
The first, the present invention tackles removing suspension, overcomes the drawback that traditional trashrack pollutant stagnates in not easy-clear on trashrack.
The second, Fencing system is provided with the sensor of induction drag force size automatically, when the suspension on current comparatively urgency or fence is more, the pressure that trashrack bar is subject to will increase, power is passed to controller by sensor at any time, controller controls electric rotating machine again and rotates, and trashrack bar is dug immediately, is slipped in blowpit by the effect of suspension self gravitation, achieve the Automated condtrol not needing manpower, significantly reduce the input of manpower.
