Description
Technical field:
The present invention relates to a kind of collapsible unidirectional backwater gate, belong to water conservancy barrage technical field.
Background technology:
In current hydraulic engineering, in river course, mainly adopt rubber dam, dull and stereotyped open-close sluice gate and hinge dam etc. to retain river, rubber dam is adopted to carry out dash, life-span is short, generally just need to change at 10-12, every 2-3 needs frequent maintenance maintenance, needs cofferdam not only to delay operation but also consumed a large amount of manpower and materials, and poor stability, be easily subject to the destruction of upstream floating thing and human factor.Dull and stereotyped open-close sluice gate cost is high.Generally must adopt pier in concrete between 10-20 rice, have a strong impact on flood passage requirement, need transform and add wide river course, and stressed instability, built on the sand, poor safety performance, and easily blocked a large amount of silt, stone and floating thing, make gate can not collapse, occur major accident.Operationally, mainly hydraulic jack plays a supportive role on hinge dam, and hydraulic jack is outside exposed for a long time, is easy to corrosion occurs, and affects the application life of hydraulic jack.Its seal is also easy to aging, and the silt simultaneously in river course is easy to enter hydraulic jack, causes the damage to hydraulic jack, thus affects the operation on whole dam.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of structure simple, practical and convenient, convenient operation, the duration is short, reasonable stress, safety and firmness, long service life, with low cost, and flood discharge is quick, is convenient to the collapsible unidirectional backwater gate safeguarded.
Object of the present invention can be reached by following measure: a kind of collapsible unidirectional backwater gate, it is characterized in that it comprises base, wherein a wing base is flexibly connected the lower end of overall water retaining facing, opposite side base is flexibly connected the lower end of foldable support, the upper end of foldable support is flexibly connected with the middle part of overall water retaining facing, the inner side of foldable support connects piston push rod, each piston push rod all connects a hydraulic jack, piston push rod, hydraulic jack is located between overall water retaining facing and foldable support, foldable support is connected and composed by baffle plate active connection by lower support element and upper supporting piece.
In order to realize object of the present invention further, described foldable support is collapsible flashboard, and collapsible flashboard is connected and composed by baffle plate active connection by lower flashboard and upper flashboard.
In order to realize object of the present invention further, described foldable support is made up of foldable support frame, and each foldable support frame is connected and composed by baffle plate active connection by lower support frame and upper support frame.
In order to realize object of the present invention further, described piston push rod is connected with the inner side of the baffle plate active connection of foldable support.
In order to realize object of the present invention further, described piston push rod is uniformly distributed.
In order to realize object of the present invention further, described overall water retaining facing is the water retaining facing of curved surface steel structure.
The present invention can produce following good effect compared with the prior art: the present invention includes foldable flashboard and monolithic water retaining facing, drives the flexible of hydraulic push rod thus drive rising and falling of panel and flashboard by the hydraulic cylinder be connected with hydraulic system.When gate is raised to requirement height, upper lower flashboard is interlocked, and play main supporting role, hydraulic jack now only plays auxiliary supporting role.After gate is opened completely, be now maximum state of retaining, connect basis form fixed support by base, two steel structure panels and flashboard form the structure of firm triangle solid under middle twisted axis connects, and reasonable stress, safety factor is large.Solve the restriction of dull and stereotyped open-close sluice gate height of dam generally under 7 meters, because bottom is that triangular form structure stress is the most stable, the most rationally, can dash 20 meters of height.The present invention can be adjusted to arbitrarily required water retaining height as required in the process of rising and falling, and arbitrarily can regulate water level, practical and convenient.The present invention in use, the two ends of panel are connected with quaywall close contact, no matter be dash state or collapse dam state, the present invention is elevated the hydraulic test that adopts all in the structure closed, any floating thing and silt, and stone can not impact the lifting of gate, and hydraulic test can not be impaired, improve service life, decrease maintenance frequency, extend the application life of hydraulic test.The present invention, in construction, need not consider the restriction of river width, does not need to change flood discharge river, and centre does not need middle pier, reaches synchronously rising and falling of gate, so can not block water, overall cost saves about 20% than the dull and stereotyped locks that open and close.Structure of the present invention is simple, and convenient operation, the duration is short.Owing to being that steel make, be not afraid of floating thing and artificial destruction.During maintenance, do not need cofferdam, application life is generally at 30-50.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of dash state of the present invention;
Fig. 2 is the structural representation of dam state of collapsing of the present invention;
Fig. 3 is the connection diagram of the foldable support part of one embodiment of the present invention;
Fig. 4 is the connection diagram of the foldable support part of another embodiment of the invention.
Detailed description of the invention: the preferred forms of the present invention below in conjunction with accompanying drawing elaborates:
Embodiment 1: a kind of collapsible unidirectional backwater gate (see Fig. 1, Fig. 2, Fig. 3), it comprises base 1, wherein a wing base 1 is connected with the lower end of the overall water retaining facing 3 of gusset by hinge 2, opposite side base 1 connects the lower end of foldable support 4 by hinge 2, the foldable support 4 of the present embodiment is collapsible flashboard, and the upper end of collapsible flashboard 4 is connected by middle hinge shaft 8 with the middle part of overall water retaining facing 3.Collapsible flashboard 4 passes through baffle plate active connection 5(and baffle plate connecting hinge 5 by lower flashboard 4-1 and upper flashboard 4-2) connect and compose, the inner side of collapsible flashboard 4 connects equally distributed piston push rod 6(and also can connect piston push rod 6 in the inner side of the baffle plate active connection 5 of collapsible flashboard 4 as required), each piston push rod 6 all connects a hydraulic jack 7, piston push rod 6, hydraulic jack 7 is placed between overall water retaining facing 3 and collapsible flashboard 4, overall water retaining facing 3 is preferably the water retaining facing of curved surface steel structure, lower flashboard 4-1 and upper flashboard 4-2 is steel structure panel.
