Description
Technical field
The present invention relates to hydraulic gate, be in particular a kind of gate is divided into two, relies on gravity to realize opening and closing, under
Double door leafs hydraulic gate of gate dive.
Background technology
At present, the hydraulic gate that China commonly uses mainly has vertical type plane steel gate, gates of segmental shape and tradition double leaf gate,
Existing gate form is required for the opening-closing process relying on high-power headstock gear to complete gate, in opening-closing process headstock gear overload or
Electric power deficiency causes the malfunctioning phenomenon that maybe cannot open and close of keying to happen occasionally.High-power headstock gear has one for power distribution infrastructure
Provisioning request.This makes under condition deviation environment, the medium and small reservoirs that such as mountain area storage capacity is little, head is high, tradition hydraulic gate
Technology exists and actual motion environment does not matches that problem, thus reduces sluice reliability of operation.Meanwhile, existing water conservancy project lock
Door is up opening a sluice gate, and causes keying platform structure height excessive, and structural seismic capacity is poor.
Summary of the invention
For avoiding the deficiency existing for above-mentioned prior art, the present invention proposes double door leafs hydraulic gate that a kind of gravity opens and closes,
, head height medium and small reservoirs little to the storage capacity for remote mountain areas, basic condition deviation, it is to avoid use high-power headstock gear
Drive form and higher big gate structure, decrease single gate size and weight, increases anti-seismic performance, improves sluice and runs
Reliability, ensure water conservancy projects safe and reliable operation.
The present invention solves that technical problem adopts the following technical scheme that
Being structurally characterized in that of double door leafs hydraulic gate that gravity of the present invention opens and closes:
Formed lock hole by both sides gate pier and gate floor, double leaf gate, described double leaf gate split are set in described lock hole
It is set to upper lock gate and tail gates；The framed bent supporting gate includes back timber and T section column, fixes in the bottom of described back timber
Fixed pulley, gate is had to be positioned in the section formed by described gate pier, gate floor, column and back timber；
Upper lock gate hanger is set at the top of described upper lock gate, tail gates hanger is set at described tail gates top, walks around
The two ends of the fixed length steel cable of fixed pulley are fixing with upper lock gate hanger and tail gates hanger respectively to be connected, and makes described upper lock gate and Xia Zha
Door utilizes the suspention of fixed length steel cable in vertical state and can upper and lower translation linkage in corresponding brake application gate slot and tail gates groove；
Arranging described upper lock gate and have inner chamber, with described inner chamber as storage chamber, described storage chamber is respectively provided with top water inlet
Mouthful, bottom discharge mouth and top vent hole, utilize described top water inlet in described inner chamber water filling to increase the weight of upper lock gate
Amount, utilizes the water-retention in described bottom discharge mouth discharge inner chamber to alleviate the weight of upper lock gate, utilizes described top vent hole real
Aerofluxus when water filling now or draining or air inlet, be provided with control valve on described bottom discharge mouth；
Order:
The weight of tail gates is W11, and suffered by tail gates, maximum buoyancy is W12；And have: W1=W11-W12；
The upper lock gate weight when internal vent is W2, and the weight when inner chamber water-filling is W3；
