Description
Technical field
The utility model belongs to hydraulic engineering and chokes water hydraulic self-control gate, particularly a kind of sprocket-type hydraulic automatically-controlled shutter gate in flood releasing structure.
Background technology
The large and medium-sized defective sluice in the current whole nation has several ten thousand, is implementing the reinforcement work of defective sluice, and general arrangement form is that sluice is blocked in the build of downstream, Longkou.
There is a kind of hydraulic automatically-controlled shutter gate based on coagulation structure, it is the gate of a kind of pair of fulcrum band connecting rod, its Men Tiwei prefabricated reinforced concrete structure, door body is hinged on buttress by supporting leg seat, the supporting leg seat bottom of a body is hinged at its other end of connecting rod of buttress upper articulation, the front portion of door body is provided with crash bearer, abutment wall is provided with air vent.Its volume is large, and Heavy Weight, due to the limitation of structure, the scope of application is restricted, and promotes universal not enough.
Utility model content
The purpose of this utility model is to provide a kind of sprocket-type hydraulic automatically-controlled shutter gate, its novel structure, opens and closes flexibly, not only can utilize the keying of upper pond level autocontrol valve, do not need other dynamic force-summing device, automatic level-controlling is accurate, operates steadily flexibly, and cost is low, lightweight, convenient management, safety, save man power and material, maintaining is convenient, and the scope of application is wide.
The purpose of this utility model is achieved in that a kind of sprocket-type hydraulic automatically-controlled shutter gate, in lock chamber, the both sides of bottom longitudinally arrange symmetrical strip firm banking respectively, respectively affixed one end of vertical chain on the end face of the firm banking of every firm banking end facing water side, chain coordinates sprocket wheel is installed, chain containing is combined with sprocket wheel, the other end of chain is fixed on sprocket wheel, not by chain contain coordinate sprocket wheel side affixed support arm, the other end of support arm affixed gate sheet, when gate sheet is positioned at dash position, match with lock floor in the base of gate sheet, the dual-side of gate sheet matches with the two side of lock chamber respectively, the dual-side and base of gate sheet arrange weather strip respectively, lock chamber is closed by gate sheet, when gate sheet closes lock chamber, the angle of gate sheet and plumb line is 10 °-15 °.
Operating principle of the present utility model:
The automatic control of sprocket-type hydraulic automatically-controlled shutter gate is that before utilizing lock, hydraulic pressure reaches the open and close of gate to the conduct oneself with dignity unbalance formation rotating torque of the opposing torque formed of the forward moment of gate sheet and gate sheet.Fulcrum place sprocket wheel adds forward moment when starting gate, and when gate falls after rise, sprocket wheel is applied with damping feedback moment, reaches gate and raises with upper pond level, gate opening earial drainage gradually, upper pond level declines, and gate returns gradually and closes retaining, and upper pond level is remained in the scope of requirement.Sprocket-type hydraulic automatically-controlled shutter gate without clashing into and patting phenomenon, uses safer in running.
The utility model is by gate sheet, support arm (arc steel door can be made also can be plain batton door), fixed bearing, sprocket wheel, and the parts such as chain form.One end of chain is fixed on fixed bearing front end, the other end of chain is fixed on sprocket wheel, when upland water flow increases, gate sheet upper pond level is raised, when the moment of flowing pressure to gate sheet fulcrum is greater than the moment that gate sheet is heavy and frictional resistance is to gate sheet fulcrum, gate sheet is opened to certain inclination angle automatically, until when flowing pressure moment about point of support equals gate sheet weight moment about point of support under this inclination angle, reach the new balance under this flow.When flow is constant, opening angle is also constant.And when upstream flowrate reduces to a certain degree, when making the heavy moment about point of support of gate sheet be greater than flowing pressure and frictional resistance moment about point of support, sprocket-type hydraulic automatically-controlled shutter gate can return voluntarily and close certain inclination angle, reach the new balance under this flow.On chain, certain displacement is had at the process central bearing point sprocket wheel of gate sheet Push And Release, the reverse damping torque of chain to sprocket wheel makes the open and close of gate more steady, therefore, sprocket-type hydraulic automatically-controlled shutter gate plate has does not need open/close machinery and corresponding establishment, do not need manual operation, completely by current control automatically, more steadily safer feature in time.
The feature of sprocket-type hydraulic automatically-controlled shutter gate:
Be widely used: sprocket-type waterpower self-control reprint gate can be widely used in rivers, reservoir spillway, channel, urban flood defence retaining, in the engineerings such as power station.
For reservoir spillway: automatically can regulate storage capacity, play the most high benefit of reservoir, guarantee reservoir safety again.Not only greatly reduce flood control level, but also can submerge loss have been reduced, also can improve water storage level.
For power station stem and forebay water-break: by local hydrographic features, in conjunction with installed capacity, maximum economic benefit can be tried to achieve.If forebay sluices, sprocket-type hydraulic automatically-controlled shutter gate discharging capacity is large, and reaction speed is fast.
For shipping and field irrigation: can automatically regulate canal water level, meet navigable depth and irrigation water needs and can keep designing ordinary water level, ensure the flow of inlet water of water intaking head.Gate does not affect lower discharge; In irrigated area, irrigating gate added downstream sprocket-type waterpower self-control reprint lock can solve water inlet sand washing problem, and after gate opening, silt washes away from pocket floor, prevents silt from entering water diverting structure.
For urban environmental protection landscape engineering: be a kind of well choke water building, stable water surface view can be provided, can urban ecological environment be improved, simultaneously can solve again river course flood discharge problem.
Small investment, easy construction, cost are reasonable, stable, convenient management safety.
Preresearch estimates sprocket-type waterpower self-control reprint gate cost is only about 70% of conventional gate; Ability of regulation and control strengthens, and construct simple and easy, the duration is short, and maintaining is convenient.It mainly by upper pond level automatic controlling gate, does not need personal management, does not also need other dynamic force-summing device.
Principle is unique, chain and sprocket wheel damping action is delicate, structure is simple, easily manufactured, security of operation.
The requirements such as the lock that can need according to user is high, lock is wide, priming level, return water level, design various sizes, the sprocket-type hydraulic automatically-controlled shutter gate of various material.
Automatically rise and close, automatic level-controlling is accurate.Effect stability inferior in chain damping during operation is better.Convenient management safety, economize people, save trouble, save time, laborsaving.Unrivaled advantage in the unexpected flood of reply especially.Hydraulic automatically-controlled shutter gate needs spare and accessory parts maintenance expenditures usually hardly, can alleviate riverbed silt deposit year by year rise problem.
The utility model novel structure, open and close flexibly, not only achieve the keying utilizing upper pond level autocontrol valve, do not need other dynamic force-summing device, automatic level-controlling is accurate, operate steadily flexibly, and cost is low, lightweight, convenient management, save man power and material, maintaining is convenient, and the scope of application is wide.
