Compared with the prior art, technical solution 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, at it
Gallery is added in the dam foundation, hydraulic oil pipe is fixed on the side of gallery, gallery and the dam foundation to hydraulic cylinder and drive link activity space
Hole to be provided be connection, be highly convenient for overhauling in this way, no matter river Zhong Shui has mostly deep, silt has mostly thick, does not influence equipment
Maintenance, 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 in such situation；A kind of dam
After have water, gallery is added in the dam foundation, hydraulic oil pipe is fixed on gallery inner wall, 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 dam foundation, and the hydraulic oil pipe of each hydraulic cylinder is fixed on the unification of gallery inner wall
It being connected on the hydraulic controlling pump work for being arranged on river bank control room, the hydraulic cylinder being embedded in the dam foundation is connected with gallery,
It can be completed in this way in repair apparatus by gallery, without the operation in river muddy water, in order to the inspection of hydraulic cylinder and oil pipe
It repaiies.
Further, the hydraulic cylinder by the hydraulic circuit pipeline being embedded in dam foundation gallery, is uniformly connected to setting
On the hydraulic controlling pump work in river bank control room, the stroke of hydraulic cylinder is controlled by hydraulic controlling pump work system, from
And it realizes vertical dam and puts dam.
Hydraulic rotating lever dam of the present invention is simple in structure, and putting dam, to found dam fast, puts and is close to riverbed behind dam and does not block water, safely may be used
It leans on, sturdy and durable, maintenance is convenient, long lifespan, not by water quality and territory restriction.
The problems such as present invention had both overcome blocking water for automatic panel-turnover dam, floating material casey, sediment siltation；Rubber is overcome again
Dam is fragile, easy to aging, rise, the dam time of collapsing it is long, the defects of safety, 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.
