Abstract
Crouch gate under bottom-shaft type, it is related to hydraulic engineering technical field, including lower shaft, lock gate leaf, hydraulic headstock gear, lower shaft is supported on gate branch free bearing, gate branch free bearing is fixed on river bed by embedded part, lock gate leaf is fixedly connected on lower shaft, and the telescopic end of hydraulic headstock gear is connected by gate arm with lock gate leaf；The gate arm is in A types, gate arm includes first support arm, second support arm and the 3rd support arm being wholely set, first support arm and two sides that second support arm is A type gate arms, one end and the telescopic end of hydraulic headstock gear that first support arm is connected with second support arm are hinged, the other end of first support arm is fixedly connected with the other end of second support arm with lock gate leaf, one end of 3rd support arm and the middle part of first support arm are connected, and the middle part of the other end and second support arm is connected.The headstock gear of traditional bottom-shaft type gate is transplanted to outdoor and connecting lever is changed into support arm is connected on lock gate leaf by the present invention, and eliminating keying lock chamber and bringing reduces cost.
Description
Technical field
The present invention relates to the structure of hydraulic engineering technical field, more particularly to gate.
Background technology
Gate is indispensable equipment in existing hydraulic engineering.Closed shutter can raise upper pond level with flood retention, gear tide, retaining, the need for meeting upstream water intaking or navigation；Starting gate with flood discharge, sand surfing, water intaking or according to the need for downstream water demand can adjust flow.Existing gate includes lower shaft, and lock gate leaf is fixed on lower shaft, and one end connecting lever of lower shaft, telescopic end and the connecting lever of hydraulic headstock gear are hinged.The gate of this mode needs to build hoist chamber, and cost is high.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided the gate that crouched under a kind of bottom-shaft type of direct drive.
The object of the present invention is achieved like this：Crouch gate under bottom-shaft type, including lower shaft, lock gate leaf, hydraulic headstock gear, lower shaft is supported on gate branch free bearing, and gate branch free bearing is fixed on river bed by embedded part, lock gate leaf is fixedly connected on lower shaft, and the telescopic end of hydraulic headstock gear is connected by gate arm with lock gate leaf；The gate arm is in A types, gate arm includes first support arm, second support arm and the 3rd support arm being wholely set, first support arm and two sides that second support arm is A type gate arms, one end and the telescopic end of hydraulic headstock gear that first support arm is connected with second support arm are hinged, the other end of first support arm is fixedly connected with the other end of second support arm with lock gate leaf, one end of 3rd support arm and the middle part of first support arm are connected, and the middle part of the other end and second support arm is connected.
Preferably, water gate sealing device is set on the lower shaft, the side antipriming mutually rubbed with seepproof screen in river course is all connected with the both sides of the lock gate leaf.
The operation principle of the present invention：Switch board sends instruction-Oil pump electrical machinery startup-hydraulic cylinder action-gate opening/closing.
Integrated hydraulic headstock gear piston rod stretches out, and gate arm down does circular shaft motion by the connection of lock gate leaf and lower shaft.Of the invention in structure make the connecting lever being connected on lower shaft into gate arm one end is rigidly connected with external headstock gear one end with lock gate leaf compared with traditional bottom-shaft type steel-slag sand, and rotating manner is that lock gate leaf does half circular motion around lower shaft.During gate dash, gate lower shaft front end presss from both sides the sealing mode of rubber using iron plate, and side sealing uses V-type watertight rubber, forms a U-shaped water-stopping end.During gate excessively stream, gate is changed into the over-current state that lies low by setting dash, and the side sealing of gate rubs sealing with seepproof screen all the time, and gate end water and lower shaft rub sealing.
The advantage of horizontal gate and lower shaft gate under perfect adaptation of the present invention.The headstock gear of traditional bottom-shaft type gate is transplanted to outdoor and connecting lever is changed to support arm is connected on lock gate leaf, eliminating keying lock chamber and bringing reduces cost.Space is saved.For to gate opening/closing space requirement is high and upstream excessively stream stone more than in the case of（Sleeping gate uses the easy card stone of pattern of branch free bearing under commonly）, save cost and space and can effectively open and close（The motion of extraneous stone is directly from gate flap excessively on gate opening/closing without influence）.
Brief description of the drawings

Fig. 2 is Fig. 1 top view.
Structural representations of the Fig. 3 for the present invention in gate excessively stream.
Embodiment
As Figure 1-3, crouch gate under bottom-shaft type, including lower shaft 3, lock gate leaf 4, hydraulic headstock gear 1, lower shaft 3 is supported on gate branch free bearing 6, gate branch free bearing 6 is fixed on river bed by embedded part, lock gate leaf 4 is fixedly connected on lower shaft 3, and the telescopic end of hydraulic headstock gear 1 is connected by gate arm 2 with lock gate leaf 4.Water gate sealing device 5 is set on lower shaft 3, the side antipriming 10 mutually rubbed with seepproof screen in river course 9 is all connected with the both sides of lock gate leaf 4.
Gate arm 2 is in A types, gate arm 2 includes first support arm 2-1, second support arm 2-2 and the 3rd support arm 2-3 being wholely set, first support arm 2-1 and second support arm 2-1 is two sides of A types gate arm 2, one end and the telescopic end of hydraulic headstock gear 1 that first support arm 2-1 is connected with second support arm 2-2 are hinged, the first support arm 2-1 other end is fixedly connected with the second support arm 2-2 other end with lock gate leaf 4,3rd support arm 2-3 one end is connected with first support arm 2-1 middle part, and the other end is connected with second support arm 2-2 middle part.
The present invention is applied to drift sand and the more river of stone, it is not necessary to independent lock chamber.It is simple and reliable for structure.
1st, integrated hydraulic hoists：The driver element of gate, controls the driving of integrated motor to perform the stretching motion of hydraulic cylinder by long distance electric.
2nd, gate arm：Headstock gear is connected with lock gate leaf, transmission pulling force and thrust.
3rd, lower shaft：Connect the rotating shaft of lock gate leaf and embedded part.
4th, lock gate leaf：Dash, as shown in Figure 1 when gate dash 7 when erected.Excessively stream when lying low, it is as shown in Figure 3 when gate excessively stream 8.
5th, gate sealing：Sealing effect is played to downstream by being connected with gate lower shaft.
