Description
Technical field
The present invention relates to hydraulic engineering apparatus field, be specifically related to a kind of water storage flood discharge device.
Background technology
In water storage flood discharge device, water storage flood discharge valve is essential elements.Making a general survey of water storage flood discharge valve both domestic and external, is mostly adopt flap valve, leather bag charge valve or the lift valve that crouches afterwards.
Wherein, flap valve arranges hinge crossbearer in the middle and lower part of valve plate both sides to carry out water storage flood discharge on clump, for flood discharge when valve plate turns to level along horizontally disposed hinge, flood passes through from the upper and lower surface of valve plate, and for water storage when valve plate turns to vertical state along described hinge.But in each flood discharge flap valve easily by water in branch or wood damage, and maintenance cost is high.Leather bag charge valve is then for being used for the valve of flood discharge when being used for water storage, venting during inflation.But due to the impact that snow and rain is white, freezing and the sun tans by the sun, leather bag charge valve easily rots, and its application life is short.
Rear sleeping lift valve is modal is utilize single-acting three-section type plunger case by valve plate jack-up and support valve plate water storage, and three segmented column plug cylinders to bounce back to cylinder body length be three/for the moment valve plate is forgotten about it backward for flood discharge.But it has following defect, 1) once the oil cylinder of rear sleeping lift valve damages, certain control element damages in pipeline leakage or hydraulic system, then namely automatically fell at the impact lower valve plate of current and affected water storage and landscape effect; 2) in annual flood impacts, sandstone is piled up in rotating shaft place that the support valve plate below valve plate rotates, and then the flexibility that when hindering valve plate to be elevated, steel cylinder rotates; 3) due to the impact of natural environment, long-term exposed plunger case surface easily rust corrosion, this not only affects attractive in appearance, and affects the flexible flexibility of plunger case; 4) this valve is when needs flood discharge, needs first to shed plunger case jacking active force upwards, then relies on the water pressure of its valve plate upstream face to be overwhelmed by valve plate, is pushed back by plunger rod in plunger case, and thus its valve plate speed of falling is slow; And facts have proved, the valve of this structure produces when valve plate declines creeps and clashes into, and easily damages oil cylinder, valve plate, steel cylinder and bearing support.
In addition, the water storage flood discharge valve disclosing other kind is also had in prior art.As patent CN201320513732.1 provides a kind of sunk type plane to go straight up to steel-slag sand, be provided with Men Ku below the base plate of lock chamber, extend to a bottom of the reservior portion bottom gate slot, gate slot top extends to lock chamber top, and during gate opening, gate flap sinks to entering Men Ku along gate slot.Gate flap top is provided with cover plate, and headstock gear oil cylinder is located at a body inside, and headstock gear piston rod one end is fixed in the keying frame at gate slot top, is respectively equipped with top, end hydrosphere bottom gate flap top and cover plate, gate flap.This utility model is simple to operate, reliable, novel structure, and dash of controlling flood also effectively prevents Sediment Siltation, without the need to annex, do not limit by headway, space is penetrating, and easy and surrounding enviroment are coordinated, and can artificial waterfall be formed during the unlatching of gate local, there is certain landscape effect.But type of going straight up to the up and down gate that this patent provides also needs the booster action of the electric equipments such as hoist engine, and its complex structure, effect is general.
Separately have in patent application CN201410151458.7 and disclose a kind of hydraulic lifting dam, comprise movable dam plate, described movable dam plate bottom is hinged, the hydraulic pressure cylinder assembly supported in " people " word with described movable dam plate is provided with at the land side of movable dam plate, described hydraulic pressure cylinder assembly comprises the single-unit hydraulic cylinder of multiple arranged, the cylinder body of described each hydraulic cylinder is interconnected, described hydraulic cylinder reversed arrangement, piston rod and the undersetting of downward layout are hinged, and the piston rod upwards arranged and the upper bracket be located on described movable dam plate are hinged.This invents this hydraulic lifting dam provided, and sound construction is reliable, lifting dynamics foot, and rapidly, flood fighting hydraulic impact is strong, and safety is high in response.But the structure on this hydraulic lifting dam is too complicated, practicality is not high.And turning over hydraulic pressure dam under the cambered surface steel provided in the movable dam that patent application CN201410174254.5 provides and patent CN201420658795, also to there is structure all equally too complicated, the problem that practicality is extremely low.
A kind of river fender water storage generating flood discharge dam utilizing hydraulic oil cylinder barrel to control water storage plate lifting of the present inventor's earlier application in patent application CN201310221315.4, hydraulic oil cylinder barrel is provided with before clump, piston rod is provided with in hydraulic oil cylinder barrel, piston rod and above clump hinge connect, the front portion of hydraulic oil cylinder barrel is fixed among the Trolley case of setting, support bar is provided with in Trolley case both sides, the upper hinge of support bar and water storage plate connects, below water storage plate, be provided with bottom hinge, below Trolley case, be provided with light rail.Separately have in patent CN201310007397.2 to also provide and similar to this application theory structure block water device.But be all that cylinder piston rod drives valve plate forward when promoting (directions along current) fall down backward, cylinder piston rod drives valve plate forward upright when pulling backward in these inventions.Thus the problem that sandstone is piled up in the upstream proximity of the rotating shaft that the support valve plate below valve plate rotates cannot all thoroughly be solved.Meanwhile, the piston rod provided in these patents and piston rod are all in the position of vicinity parallel with hardened layer, and easily dirty near such piston rod and piston rod, thus piston rod is easily damaged.
Up to the present, also there is not yet one on the market and can overcome above-mentioned deficiency, especially its rotating shaft place sandstone piles up problem, and process structure is simple, stable and reliable operation, and repair and maintenance is convenient, long service life, the water storage flood discharge device easily manufactured.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, especially solve its rotating shaft place sandstone and pile up problem, provide a kind of process structure simple, stable and reliable operation, repair and maintenance is convenient, long service life, the water storage flood discharge device easily manufactured.Before water storage flood discharge device provided by the invention comprises a kind of piston rod pushing belt move valve plate forward (against the current flow path direction) hold down flood discharge, piston rod post-tensioning then backward (Parallel to the flow direction) rise the valve of valve plate water storage.
