Abstract
Gate crouches under lower shaft formula relates to hydraulic engineering technical field, and including lower shaft, gate flap, hydraulic hoist machine, the lower shaft supports on a gate free bearing, and a gate free bearing is fixed in the river bed through burying the piece, and gate flap fixed connection is on the lower shaft, and hydraulic hoist machine's flexible end passes through the gate support arm and is connected with gate flap, the gate support arm is the A type, and the gate support arm is two limits of A type gate support arm including integrative first support arm, second support arm and the third support arm that sets up, first support arm and second support arm, and first support arm is articulated mutually with hydraulic hoist machine's flexible end with the one end that the second support arm is connected, and the other end of first support arm is equal and gate flap fixed connection with the other end of second support arm, and the one end of third support arm is connected with the middle part of first support arm, and the other end is connected with the middle part of second support arm. The utility model discloses be transplanted to the headstock gear of traditional lower shaft formula gate outdoor and change the turning arm into support arm and connect on gate flap, cancelled and opened and close the lock chamber and bring reduce cost.
Description
Technical field
The utility model relates to hydraulic engineering technical field, particularly relates to the structure of gate.
Background technology
Gate is indispensable equipment in existing hydraulic engineering.Closed shutter can raise upper pond level with flood retention, gear tide, retaining, to meet upstream water intaking or the needs of navigation；Starting gate can with flood discharge, sand surfing, water intaking or according to downstream water demand need regulate flow.Existing gate includes that lower shaft, lock gate leaf are fixed on lower shaft, and one end of lower shaft connects connecting lever, and the telescopic end of hydraulic headstock gear is hinged with connecting lever.The gate of this mode needs to build hoist chamber, and cost is high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that sleeping gate under the bottom-shaft type of a kind of direct driving.
The purpose of this utility model is achieved in that under bottom-shaft type sleeping gate, including lower shaft, lock gate leaf, hydraulic headstock gear, lower shaft is supported on gate and props up on free bearing, gate props up free bearing and 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 with lock gate leaf by gate arm；Described gate arm is A type, gate arm includes the first support arm, the second support arm and the 3rd support arm being wholely set, first support arm and the second support arm are two limits of A type gate arm, one end that first support arm and the second support arm connect is hinged with the telescopic end of hydraulic headstock gear, the other end of the first support arm and the other end of the second support arm are all fixing with lock gate leaf to be connected, one end of 3rd support arm is connected with the middle part of the first support arm, and the middle part of the other end and the second support arm connects.
Preferably, described lower shaft arranges water gate sealing device, be all connected with the side antipriming rubbed mutually with seepproof screen in river course in the both sides of described lock gate leaf.
Operation principle of the present utility model: 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 by the connection of lock gate leaf with lower shaft and moves.The connecting lever being connected on lower shaft, compared with traditional bottom-shaft type steel-slag sand, is structurally made into gate arm one end and is rigidly connected with lock gate leaf with external headstock gear one end by the utility model, and rotating manner is that lock gate leaf does half circular motion around lower shaft.During gate dash, gate lower shaft front end uses the sealing mode of iron plate folder rubber, and side sealing uses V-type watertight rubber, forms a U-shaped water-stopping end.When stream crossed by gate, gate is changed into, by erectting dash, the over-current state that lies low, and the side sealing of gate rubs with seepproof screen sealing all the time, and gate end water and lower shaft rub sealing.
The advantage of the utility model perfect adaptation time horizontal gate and lower shaft gate.The headstock gear of traditional bottom-shaft type gate it is transplanted to outdoor and connecting lever is changed into support arm is connected on lock gate leaf, eliminating keying lock chamber and bring reduction cost.Save space.For high to gate opening/closing space requirement and on swim across flowstone head many in the case of (under Pu Tong, sleeping gate uses the pattern easy card stone of a free bearing), provide cost savings and space can effectively open and close (motion of extraneous stone is directly crossed gate opening/closing without affecting from gate flap).
Accompanying drawing explanation
Fig. 1 is the utility model structural representation when gate dash.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the utility model structural representation when stream crossed by gate.
Detailed description of the invention
As Figure 1-3, sleeping gate under bottom-shaft type, including lower shaft 3, lock gate leaf 4, hydraulic headstock gear 1, lower shaft 3 is supported on gate and props up on free bearing 6, gate props up free bearing 6 and 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 with lock gate leaf 4 by gate arm 2.Lower shaft 3 arranges water gate sealing device 5, is all connected with in the both sides of lock gate leaf 4 and the side antipriming 10 of seepproof screen in river course 9 phase friction.
Gate arm 2 is in A type, gate arm 2 includes the first support arm 2-1, the second support arm 2-2 and the 3rd support arm 2-3 being wholely set, first support arm 2-1 and two limits that the second support arm 2-1 is A type gate arm 2, one end that first support arm 2-1 and the second support arm 2-2 connects is hinged with the telescopic end of hydraulic headstock gear 1, the other end of the first support arm 2-1 and the other end of the second support arm 2-2 are all fixing with lock gate leaf 4 to be connected, one end of 3rd support arm 2-3 is connected with the middle part of the first support arm 2-1, and the middle part of the other end and the second support arm 2-2 connects.
The utility model is applicable to drift sand and the more river of stone, it is not necessary to individually lock chamber.Simple and reliable for structure.
1, integrated hydraulic hoists: the driver element of gate, controls the driving of integrated motor by long distance electric and performs the stretching motion of hydraulic cylinder.
2, gate arm: headstock gear is connected with lock gate leaf, transmission pulling force and thrust.
3, lower shaft: connect the rotating shaft of lock gate leaf and embedded part.
4, lock gate leaf: dash when erected, when gate dash 7 as shown in Figure 1.Stream is crossed, when stream 8 crossed by gate as shown in Figure 3 when lying low.
5, gate sealing: by being connected sealing effect that downstream is played with gate lower shaft.
