Cylinder pressure controls, and hydraulic cylinder is arranged on to block when dam is found in the upstream of water panel and controlled by hydraulic cylinder.
Compared with the prior art, technical scheme provided by the invention has the beneficial effect that：
The present invention is in patent of invention（The patent No.：ZL 2016 1 0213817.6）On the basis of hydraulic rotating steel dam, in its dam foundation
In set up gallery, hydraulic oil pipe is fixed on the side of gallery, gallery and the dam foundation to the pre- of hydraulic cylinder and drive link activity space
Box out is connection, is so highly convenient for overhauling, no matter river course reclaimed water has more deeply, silt has thickness more, does not influence the inspection of equipment
Repair, and hydraulic system works in dry environment entirely, greatly increases its service life.
Check dam build up after in two kinds of situation, anhydrous behind a kind of dam, the maintenance of hydraulic cylinder and oil pipe is not by water and silt
Limitation, patent of invention（The patent No.：ZL 2016 1 0213817.6）Hydraulic rotating steel dam is relatively applicable such a situation；A kind of dam
After have water, gallery is set up in the dam foundation, hydraulic oil pipe is fixed on gallery inwall, and the hydraulic cylinder being embedded in the dam foundation is to connect with gallery
, in order to overhaul.
Further, gallery is set in the described dam foundation, and the hydraulic oil pipe of each hydraulic cylinder is fixed on the unification of gallery inwall
It is connected to and is arranged on the hydraulic controlling pump work in river course bank control room, the hydraulic cylinder being embedded in the dam foundation connects with gallery,
It can so be completed by gallery in repair apparatus, without the operation in river course muddy water, in order to the inspection of hydraulic cylinder and oil pipe
Repair.
Further, described hydraulic cylinder, by the hydraulic circuit pipeline being embedded in dam foundation gallery, uniformly it is connected to setting
On the hydraulic controlling pump work in river course bank control room, the stroke of hydraulic cylinder is controlled by hydraulic controlling pump work system, from
And realize vertical dam and put dam.
Hydraulic rotating lever dam of the present invention is simple in construction, and putting dam, to found dam fast, puts and is close to riverbed behind dam and does not block water, safely may be used
Lean on, sturdy and durable, maintenance is convenient, long lifespan, not by water quality and territory restriction.
The present invention had both overcome blocking water for automatic panel-turnover dam, floating object jam, the problems such as Sediment Siltation；Rubber is overcome again
The defects of dam is fragile, easy to aging, rises, dam time length of collapsing, and security, reliability are poor, and service life is short；Also solve tradition
Need to set middle pier among when the lower shaft of steel dam is clumsy, span is big, cause to block water, cost is high, it is high to fundamental importance, the dam foundation can not be adapted to
Differential settlement, and the hydraulic cylinder solved in hydraulic pressure dam ducks in drink for a long time, influences service life, inconvenience is overhauled, unsightly
Etc. deficiency in the majority.

Embodiment
In order to be more clearly understood that technical scheme, the present invention is further described below in conjunction with the accompanying drawings.
Referring to Fig. 1-Fig. 4, the difference of water surface width is blocked according to river course, the unit of water panel 1 is blocked by some pieces and forms, its is every
The individual water panel 1 that blocks is connected firmly in the dam foundation by lower shaft 3 by rocker bar bearing 2, and drive link 4 is set in the middle of lower shaft 3 and is blocked
Water panel 1 firmly connects into an entirety, the other end connection liquid cylinder pressure 5 of drive link 4, and hydraulic cylinder 5 is fixed on the dam foundation, passed through
Flexible and stroke the length of hydraulic cylinder 4 is controlled, lower shaft is driven and blocks the rotation of water panel 1, so as to realize vertical dam, put dam
Water height is blocked with regulation.
Referring to Fig. 1-Fig. 4, gallery 8 is set, hydraulic oil pipe 7 is fixed on the inwall of gallery 8 and is uniformly connected in the described dam foundation
It is arranged on the hydraulic controlling pump work in river course bank control room, the hydraulic cylinder 5 being embedded in the dam foundation connects with gallery 8, so
It can be completed by gallery 8 in repair apparatus, without the operation in river course muddy water, in order to hydraulic cylinder 5 and hydraulic oil pipe 7
Maintenance.
Referring to Fig. 1-Fig. 4, the described material for blocking water panel 1 is steel, and shape has plate, arc or according to need
It is fabricated to different shape.
Referring to Fig. 1-Fig. 4, it is described block water panel 1 and block be provided with sealing between water panel 1, block the lower shaft 3 of water panel 1 with
Antipriming is provided between the dam foundation, the dam foundation will do water-proofing treatment to the hole to be provided of hydraulic cylinder 5 and the activity space of drive link 4, make
It forms an entirety with dam foundation surface layer.
Referring to Fig. 1-Fig. 4, described rocker bar bearing 3, firmly it is welded on the steel plate on pre-buried dam foundation surface, steel plate quilt
Reinforcing bar cage is securely attached to dam foundation surface, so that blocking water panel 1, hydraulic cylinder 5 and the dam foundation forms an entirety, reaches and blocks
Water water storage purpose.
Referring to Fig. 1-Fig. 4, described hydraulic cylinder 5, by the hydraulic oil pipeline 7 being embedded in dam foundation gallery 8, unified connection
To being arranged on the hydraulic controlling pump work in river course bank control room, stretching for hydraulic cylinder 5 is controlled by hydraulic controlling pump work system
Contracting amount, so as to realize vertical dam and put dam.Described hydraulic cylinder 5 is arranged on the downstream for blocking water panel 1, when founding dam, to shorten hydraulic pressure
The length of cylinder 5, hydraulic cylinder 5 mainly plays pulling force effect, when putting dam, the pressure by blocking the deadweight of water panel 1 and water, puts dam automatically.Institute
If the hydraulic cylinder 5 stated when founding dam, will extend the length of hydraulic cylinder 5, hydraulic cylinder 5 mainly rises and pushed away installed in the upstream for blocking water panel
Power acts on, and when putting dam, the pressure by blocking the deadweight of water panel 1 and water, puts dam automatically, and hydraulic cylinder 5 can also be dual force cylinder, this
Sample can be controlled when putting dam by hydraulic cylinder 5.
Described hydraulic lock assembly 6, it is the circular rod iron of a small cylinder control, vertical referring to Fig. 1-Fig. 4
