Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Fig. 1 to Fig. 7, high water head plane gate structure of the present invention, including gate flap 2 and with 2 liang of gate flap
Side is individually directed the gate slot 1 of cooperation, and the bottom between the gate slot 1 of two sides is ground sill 3, and the gate flap 2 includes gate flap ontology
21 and frame 22 is filled out, is provided with one with extending separately down in the lower end of 21 two sides of gate flap ontology and fills out frame 22, fill out frame 22 at two
Between formed overcurrent mouth 13, lower counterbore 4 is provided in the bottom of the gate slot 1 of two sides with extending downwardly, the frame 22 of filling out can be stretched
Enter to the lower counterbore 4 of respective side.
Wherein, the purpose for filling out frame 22 is to after gate plays lock, i.e., fill out frame 22 by lower part after gate flap 2 lifts
Cooperate with the gate slot 1 of corresponding side, to fill gate slot 1, can avoid due to the inside rock mass surface 6 of runner 14 is because of gate slot 1 in this way
There is the groove structure being mutated, and then keeps the planarization of 14 interior sidewall surface of runner, turbulent water caused by reducing because of gate slot, into
And avoid occurring cavitation corrosion cavitation phenomenon at gate slot 1, reducing the erosion to gate slot 1 acts on, and improves 1 service life of gate slot.
Certainly, without loss of generality, after gate plays lock, the overcurrent mouth 13 filled out between frame 22 positioned at two sides should be with runner
14 is corresponding, to allow water flow to pass through.In addition, in order to ensure 14 interior sidewall surface of runner is by smooth transition at gate slot 1, the present invention
The shape for being preferably provided with overcurrent mouth 13 is identical with the overflow section shape of runner 14, such as shown in attached drawing 6 and attached drawing 7,
Both for the rectangular configuration of identical size.Certainly, without loss of generality, in the shape of above-mentioned setting overcurrent mouth 13 and runner 14
In the case that overflow section shape is identical, the medial surface needs for filling out frame 22 accordingly are flat with the rock mass surface 6 of 1 oral area of gate slot
Together, as shown in Fig. 3.
In addition, lower counterbore 4 described in aforementioned present invention is to fill out frame 22 accordingly for interim accommodate in the process of the lower gate, when
When gate flap in the present invention is using structure shown in attached drawing 5, only includes gate flap ontology 21 and fill out frame 22 accordingly, this is at present
Counterbore 4 need to be set as and the corresponding blind hole structure for filling out the cooperation of frame 22.More specifically, referring to attached drawing 4,6 and of attached drawing
Shown in attached drawing 7, further preferably setting gate flap 2 further includes connecting cross beam 23 in the present invention, and connecting cross beam 23 is by two
A bottom end connection for filling out frame 22, can be improved the whole structural strength of gate flap 2 in this way；It is further provided with below ground sill 3 at this time
Sinking chamber 5 accommodates corresponding connecting cross beam 23 by sinking chamber 5, and connecting cross beam 23 is allowed to move up and down in sinking chamber 5,
And it can further preferably be arranged after sinking chamber 5 is connected to the lower counterbore 4 of two sides and form whole cavity structure.In above structure
On, it needs still to remain with certain thickness ground sill 3 above sinking chamber 5, just can avoid because sinking chamber 5 is from runner 4 in this way
Bottom surface rock mass is pierced by and is formed the groove structure of mutation, it is ensured that the smooth transition in the bottom surface of runner 4.
In addition, for the ease of being overhauled to gate slot 1 and corresponding gate flap 2, further in each gate slot 1 in the present invention
Inside be additionally provided with access path 7.It is specific then the size of gate slot 1 can be increased inside it, as shown in Fig. 3, in this way
It can be entered by the access path 7 to carry out upkeep operation.
In addition, gate flap ontology 21 is further preferably arranged in the present invention and fills out frame 22 for the ease of installing and overhauling disassembly
It is detachably connected by bolt.Without loss of generality, when being provided with connecting cross beam 23, connecting cross beam 23 with it is corresponding fill out frame 22 it
Between can also be detachably connected by bolt.
In addition, high water head plane gate structure of the present invention is further also wrapped referring to shown in attached drawing 1 and attached drawing 2
Lock chamber 8, mechanism for opening/closing 9, resigning chamber 10, sealing cover 11 and connector 12 are included, the mechanism for opening/closing 9 is mounted in lock chamber 8, described
Resigning chamber 10 is set to 8 lower section of lock chamber and is connected to gate slot 1 with lock chamber 8 by resigning chamber 10, connect in resigning chamber 10 with lock chamber 8
Place is provided with sealing cover 11, and mechanism for opening/closing 9 and gate flap 2 are sequentially connected by the connector 12 after passing through sealing cover.Wherein, it opens and closes
Mechanism 9 is the opening and closing realized by connector 12 to gate flap 2, and then realizes lower lock and the lock control of gate.More specifically, originally
Mechanism for opening/closing 9 in invention is preferably hydraulic cylinder, and corresponding connector 12 is the piston rod of hydraulic cylinder.
It is lock state under gate referring to shown in attached drawing 1 and attached drawing 7, i.e. gate flap 2 is in decentralization state, by gate flap ontology 21
Corresponding part blocks runner 14, realizes shutting off to runner 14；And lock state, i.e. door are played for gate shown in attached drawing 2 and attached drawing 6
Leaf 2, which is in, lifts state, and the overcurrent mouth 13 on gate flap 2 is aligned with runner 14 at this time, makes the smooth overcurrent of runner 14.
