Description
Technical field
The present invention relates to hydraulic gate, be in particular it is a kind of gate is divided into two, realized by gravity open and close, under
Double door leaf hydraulic gates of gate dive.
Background technology
At present, the common hydraulic gate in China mainly has vertical type plane steel gate, gates of segmental shape and traditional double leaf gate,
Existing gate form is required for completing the opening-closing process of gate by high-power headstock gear, in opening-closing process headstock gear overload or
The phenomenon that electric power deficiency causes to open and close failure or can not open and close happens occasionally.High-power headstock gear has one for power distribution infrastructure
Provisioning request.This causes under condition deviation environment, such as the medium and small reservoirs that mountain area storage capacity is small, head is high, traditional hydraulic gate
Technology there are problems that not matching that with actual motion environment, so as to reduce sluice reliability of operation.Meanwhile existing water conservancy project lock
Door be that uplink is opened a sluice gate, cause open and close platform structure it is highly excessive, structural seismic capacity is poor.
The content of the invention
To avoid the deficiency present in the above-mentioned prior art, the present invention proposes double door leaf hydraulic gates that a kind of gravity opens and closes,
To which the storage capacity for remote mountain areas, basic condition deviation is small, the high medium and small reservoirs of head, avoid using high-power headstock gear
Drive form and higher big gate structure, reduce single gate size and weight, increase anti-seismic performance, improve sluice operation
Reliability, ensure the safe and reliable operation of water conservancy projects.
The present invention adopts the following technical scheme that to solve technical problem：
Double door leaf hydraulic gates that gravity of the present invention opens and closes are structurally characterized in that：
Lock hole is formed by both sides gate pier and gate floor, double leaf gate, the double leaf gate split are set in the lock hole
It is arranged to upper lock gate and tail gates；The framed bent of support gate includes top beam and T section column, is fixed in the bottom of the top beam
There is fixed pulley, gate is located in the section formed by the gate pier, gate floor, column and top beam；
Upper lock gate lifting lug is set at the top of the upper lock gate, tail gates lifting lug is set at the top of the tail gates, is bypassed
The both ends of the fixed length steel cable of fixed pulley are fixedly connected with upper lock gate lifting lug and tail gates lifting lug respectively, make the upper lock gate and lower lock
Door upper and lower translation can simultaneously be linked using the suspention of fixed length steel cable in vertical state in corresponding brake application gate slot and tail gates groove；
Set the upper lock gate that there is inner cavity, using the inner cavity as storage chamber, the storage chamber sets top to intake respectively
Mouthful, bottom discharge mouth and top vent hole, using the top water inlet into the inner cavity water filling to increase the weight of upper lock gate
Amount, the water storage in inner cavity is discharged to mitigate the weight of upper lock gate using the bottom discharge mouth, real using the top vent hole
Exhaust or air inlet when present water filling or draining, control valve is provided with the bottom discharge mouth；
Order：
The weight of tail gates is W11, and maximum buoyancy suffered by tail gates is W12；And have：W1=W11-W12；
Weight of the upper lock gate in internal vent is W2, and the weight in inner cavity during water-filling is W3；
Described W1, W2, W3 and W11 meet condition one and condition two at the same time：
Condition one：W2 is less than W1 so that in the internal vent of upper lock gate, tail gates can decline according to gravity, and gate is beaten
Open；
Condition two：W11 is less than W3 so that after the inner cavity water filling of upper lock gate, upper lock gate can decline according to gravity, and gate closes
Close；
In the ground where the tail gates below cross section place gate floor set U-shaped dive gate slot, make it is described under
