Description
Technical field
The invention belongs to the hydraulic self-control gate in flood releasing structure is choked water in hydraulic engineering, particularly a kind of sprocket-type waterpower
Automatically-controlled shutter gate.
Background technology
National at present large and medium-sized defective sluice has tens of thousands of seats, is implementing the reinforcement work of defective sluice, general cloth
Put form sluice is blocked for the build of Longkou downstream.
There is a kind of hydraulic automatically-controlled shutter gate based on coagulation structure, be a kind of pair of gate of the fulcrum with connecting rod, its door
Body is prefabricated reinforced concrete structure, and door body is hinged on buttress by supporting leg seat, and in the connecting rod of buttress upper articulation, which is another
End is hinged on the supporting leg seat bottom of door body, the front portion of door body is provided with crash bearer, is provided with passage on abutment wall.Its volume
Greatly, weight weight, due to the limitation of structure, use range is restricted, and promotes and popularizes not enough.
Content of the invention
It is an object of the invention to provide a kind of sprocket-type hydraulic automatically-controlled shutter gate, its structure novelty, open and close flexibly, no
The keying of upper pond level autocontrol valve can only be utilized, it is not necessary to other dynamic force-summing devices, accurately, operation is flat for automatic level-controlling
Steady flexible, and low cost, lightweight, convenient management, safety, man power and material is saved, maintaining is convenient, use range
Extensively.
The object of the present invention is achieved like this：A kind of sprocket-type hydraulic automatically-controlled shutter gate, the two of bottom in the lock chamber
Side difference longitudinally disposed symmetrical strip firm banking, in the firm banking of every firm banking end facing water side
One end of vertical chain being respectively and fixedly connected with top surface, being coordinated sprocket wheel is installed on chain, chain containing is combined with sprocket wheel, chain
The other end be fixed on sprocket wheel, do not contained by chain the sprocket wheel side that coordinates affixed support arm, the other end of support arm is affixed
Gate sheet, when gate sheet is located at dash position, the base of gate sheet is engaged with lock floor, the two sides difference of gate sheet
Be engaged with the two side of lock chamber, sealing strip is respectively provided with two sides and base of gate sheet, makes gate sheet by lock chamber
Closing, when gate sheet closes lock chamber, gate sheet is 10 ° -15 ° with the angle of plumb line.
The operation principle of the present invention：
The automatic control of sprocket-type hydraulic automatically-controlled shutter gate is positive torque and the gate sheet using hydraulic pressure before lock to gate sheet
From the open and close that the unbalance formation rotating torque of the opposing torque for reforming reaches gate.At fulcrum, sprocket wheel is in starting gate
When increased positive torque, when gate falls after rise, sprocket wheel is applied with damping feedback moment, reach gate with upper pond level raise,
Gradually gate opening earial drainage, upper pond level decline, and gate is gradually returned and closes retaining, makes upper pond level remain at the scope of requirement
Interior.Sprocket-type hydraulic automatically-controlled shutter gate without shock and pats phenomenon in running, using safer.
The present invention is by gate sheet, support arm（It can also be plain batton door that arc steel door can be made）, hold-down support, sprocket wheel, chain
The parts such as bar are constituted.One end of chain is fixed on hold-down support front end, and the other end of chain is fixed on sprocket wheel, works as upland water
Flow increases, and gate sheet upper pond level is raised, and flowing pressure is to the torque of gate sheet fulcrum more than gate sheet weight and frictional resistance pair
During the torque of gate sheet fulcrum, gate sheet automatically turns on certain inclination angle, until power of the flowing pressure to fulcrum under the inclination angle
When square is equal to gate sheet weight moment about point of support, the new balance under the flow is reached.When flow is constant, opening angle is not yet
Become.And work as upstream flowrate and reduce to a certain extent, make gate sheet weight moment about point of support more than flowing pressure and frictional resistance to propping up
During the torque of point, sprocket-type hydraulic automatically-controlled shutter gate can voluntarily go back to pass to certain inclination angle, reach the new balance under the flow.
During gate sheet Push And Release, fulcrum sprocket wheel has certain displacement, chain to make the reverse damping torque of sprocket wheel on chain
The open and close of gate is more steady, therefore, sprocket-type hydraulic automatically-controlled shutter gate plate have be not required to open/close machinery and corresponding establishment,
Be not required to manual operation, completely by the timely automated control of current, more steadily safer the characteristics of.
The characteristics of sprocket-type hydraulic automatically-controlled shutter gate：
It is widely used：Sprocket-type waterpower self-control reprint gate can be widely applied to rivers, reservoir spillway, channel, city
In the engineerings such as city's flood control retaining, power station.
For reservoir spillway：Storage capacity can be automatically adjusted, reservoir highest benefit is played, is also ensured that reservoir safety.Both significantly
Reduce flood control level and can reduce again and flood loss, can also improve water storage level.
For power station stem and forebay water-break：Maximum economic effect can be tried to achieve by local hydrographic features, in conjunction with installed capacity
Benefit.If forebay sluices, sprocket-type hydraulic automatically-controlled shutter gate discharging capacity is big, and reaction speed is fast.
For shipping and field irrigation：Canal water level can be automatically adjusted, navigable depth is met and irrigation water needs can be protected
Hold design ordinary water level, it is ensured that the flow of inlet water of water intaking head.Gate is not affected on lower discharge；Under the irrigating gate of irrigated area
Trip is set up sprocket-type waterpower self-control reprint lock and can solve the problems, such as water inlet sand washing, and after gate opening, silt is washed away from pocket floor, is prevented
Silt enters water diverting structure.
For urban environmental protection landscape engineering：It is a kind of good to choke water building, using the teaching of the invention it is possible to provide stable water surface landscape, both
Urban ecological environment can be improved, while river course flood discharge can be solved the problems, such as again.
Small investment, easy construction, cost are reasonable, stable, convenient management safety.
Preresearch estimates sprocket-type waterpower self-control reprint gate cost is only the 70% or so of conventional gate；Ability of regulation and control increases
By force, construct simple, short time limit, maintaining are convenient.It mainly by upper pond level automatic controlling gate, is not required to personal management,
Also without other dynamic force-summing devices.
Principle is unique, and chain is delicate with sprocket wheel damping action, simple structure, easily manufactured, operation safety.
Can be required according to lock height, lock width, priming level, return water level that user needs etc., design various sizes, various materials
The sprocket-type hydraulic automatically-controlled shutter gate of matter.
Automatically rise and close, automatic level-controlling is accurate.During operation, in the presence of chain damping, stability is more preferable.Convenient management is pacified
Entirely, save people, save trouble, save time, laborsaving.Unrivaled advantage especially in terms of unexpected flood is tackled.Hydraulic automatically-controlled shutter gate
Usually with little need for spare and accessory parts maintenance expenditures, riverbed silt can be alleviated and is deposited year by year the problem of rising.
Present configuration is novel, opens and closes flexibly, not only achieves the keying using upper pond level autocontrol valve, be not required to
Other dynamic force-summing devices are wanted, automatic level-controlling accurately, operates steadily flexibly, and low cost, lightweight, convenient management saves people
Power and material resources, maintaining are convenient, and use range is wide.
