Description

Movable dam hydraulic pressure strut valve system
Technical field
The utility model relates to a kind of dam body movable gate, especially relates to hydraulic pressure strut gate for a kind of dam body.
Background technology
For rationally utilizing the water conservancy hydraulic power potentials, build dam and establish the lock dash on river,lake and reservior, to flood, for field irrigation, hydroelectric generation, living water use and view retaining; Between flooding period, movable dam can be opened a sluice gate flood discharge fast, reduces in time water level, avoids big flood; Movable dam hydraulic pressure brace apparatus can effectively achieve the above object.The dam body movable gate can replace the fixed weir on top, riverbed, or builds movable gate again on fixed weir and reduce the height of fixed weir, thereby reduces the possibility that the weir upstream is inundated with flood; Unobstructed obstacle during due to dam body movable gate earial drainage, so just can greatly reduce the harm that riverbed is improved year by year due to Sediment Siltation in riverbed.Traditional movable gate has in two: flap gate and rubber dam gate, they have defect separately.
The defect of flap gate is: the panel turnover sluice gate door-plate need arrange buttress, very easily hangs assorted block material during earial drainage, and easy-clear not, causes the gate opening/closing difficulty; The large-sized object that mighty torrent brings often clashes into buttress, even can cause the buttress damage; If want long-term normal the use, the regular maintenance amount is large.In addition, the concrete work amount is larger, and overall cost is higher; During earial drainage, the oblique middle part, dam that is poured into of panel turnover sluice gate door-plate has greatly reduced the flood discharge useful area together with buttress, causes earial drainage slow; During current process flap gate, torrent are patted panel (pulsation), cause vibrations, destroy dam body.
The defect of rubber dam gate is: the rubber dam project cost is high, the carcase work complexity, and the dam body installation requirement is high, long construction period.It is long that pump priming for rubber dam (or gas) fills the dam time, during earial drainage, that body water (or gas) emptying time is long; In addition, rubber dam regular maintenance amount is large, and maintenance cost crosses 1,000,000 large-scale rubber dam year according to statistics.The sharp objects that current bring easily scratches rubber dam to cut, and cut is difficult to repair, and after reparation, more again destroyed, and it is limited to repair number of times; In addition, fire is all the natural enemy of rubber dam with freezing.The aging fast defect of elastomeric material has determined rubber dam application life short (generally being no more than 10 years).Movable dam hydraulic pressure strut valve system can effectively overcome the defect of above-mentioned two kinds of gates.
The utility model content
For retaining box in above-mentioned prior art and movable gate, exist problem, the utility model provides a kind of not only gate opening quick flexible, installation and maintenance convenience, safe and reliable to operation, and the dash water level can regulate, the movable dam hydraulic pressure strut valve system that construction costs is low.Reserve-water-level can be regulated arbitrarily according to actual needs, after the gate panel is toppled over, with fixing dam crest, flush fully, and between gate without dividing pier is set, realize that full section truly drains off floodwaters.
[0004]the technical scheme that the technical problems to be solved in the utility model is taked is: it is by hydraulic cylinder (1), plunger rod (2), the first support bar (3), the second support bar (4), support bar connecting rod (5), stop (6), rotating stand (7), rotating shaft (8) and bearing pin (9), cylinder pedestal (10), support bar base (11), gate (12), hydraulic cylinder groove (13), dam body (14) base body (15), sand discharge hole (16) forms, it is characterized in that being fixedly installed base body (15) in dam body (14) downstream one side, be fixedly installed rotating stand (7) on dam body (14), described gate (12) lower end and rotating stand (7) adopt rotating shaft (8) to be movably connected, described gate (12) can be around rotating bearing (7) rotation, be provided with hydraulic cylinder (1) in the hydraulic cylinder groove (13) of dam body (14) downstream one side, described hydraulic cylinder (1) cylinder pedestal (10) is fixedly installed on hydraulic cylinder groove (13) bottom surface, plunger rod on described hydraulic cylinder (2) is movably hinged with the first support bar (3) and the second support bar (4) three by bearing pin (9), the second support bar (4) is flexibly connected by bearing pin (9) with gate (12), the first support bar (3) afterbody is connected by bearing pin (9) with the support bar base (11) on being fixed on base body (15), when the second support bar (4) and the first support bar (3) link motion stop (6) to linearly the time forces to stop it to continue motion, the second support bar (4) and the first support bar (3) laterally link into an integrated entity with support bar connecting rod (5), make its synchronized movement, toward downstream direction, sand discharge hole (16) is set at hydraulic cylinder groove (13).
[0005]operating principle of the present utility model is:
By the Motor Drive hydraulic pump, to hydraulic medium, pressurize, control hydraulic cylinder (1) action through hydraulic control component, plunger rod (2) stretches out, pushing tow the first support bar (3) and the second support bar (4) are done link motion, the first support bar (3) jack-up gate (12) rotates and is increased to design altitude around rotating bearing (7), meanwhile, when hydraulic cylinder (1) rotates slightly around cylinder pedestal (10), after gate (12) is increased to design altitude one by one, closing direction control valve oil return pipe, make in hydraulic cylinder (1) to keep rated pressure, forms a checkdam; Handle control valve the plunger rod (2) of oil cylinder (1) is retracted, drive the first support bar (3) and the second support bar (4) and do link motion in the other direction, the gate that fell (12) is the dam facing elevation extremely fixedly.In addition, also can gate (12) be fallen to corresponding height according to upper pond level and letdown flow needs, closing direction control valve oil return pipe, maintain static gate (12).
Movable dam hydraulic pressure strut valve system described in the utility model and existing movable gate are compared, and have following advantage:
By the reasonable angle of gate (12) is set, rotating stand (7) locates not produce tensile stress, less demanding to the dam foundation; Gate (12) device adopts double-cantilever structure, and mid span moment reduces more than 80%; Gate (12) and embedded part are made to soak zinc and are processed, and are difficult for corrosion, and structural reliability is high, long service life; Full steel structure, application life, result of use, reliability and safety are good, and cost performance is high; After gate (12) fell fully, be the level of state, be close to dam facing and do not block water, not block material; Hydraulic cylinder (1) drives gate (12) rotation by the first support bar (3) and the second support bar (4), and reserve-water-level can be regulated arbitrarily according to actual needs; After gate (12) reaches the design maximum elevation, the first support bar (3) and the second support bar (4) are stressed larger, and hydraulic cylinder (1) is stressed less; It is flexible, quick that gate (12) opens and closes; Installation, maintenance is simple and convenient, safe and reliable to operation.
