Overcurrent mouth 13 is formed between frame 22, is provided with lower counterbore 4 in the bottom of the gate slot 1 of two sides with extending downwardly, it is described to fill out 22 energy of frame
It enough stretches in 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, this reality
It is identical with the overflow section shape of runner 14 with the novel shape for being preferably provided with overcurrent mouth 13, such as in attached drawing 6 and attached drawing 7
It is shown, both for the rectangular configuration of identical size.Certainly, without loss of generality, in the shape and stream of above-mentioned setting overcurrent mouth 13
In the case that the overflow section shape in road 14 is identical, the medial surface for filling out frame 22 accordingly needs and the rock mass of 1 oral area of gate slot
Surface 6 is concordant, as shown in Fig. 3.
In addition, above-mentioned lower counterbore described in the utility model 4 is to fill out frame accordingly for interim accommodate in the process of the lower gate
22, when the gate flap in the utility model is using structure shown in attached drawing 5, only includes gate flap ontology 21 and fill out frame accordingly
22, lower counterbore 4 need to be set as and the corresponding blind hole structure for filling out the cooperation of frame 22 at this time.More specifically, referring to attached drawing
4, shown in attached drawing 6 and attached drawing 7, further preferably setting gate flap 2 further includes connecting cross beam 23 in the utility model, and even
It connects crossbeam 23 to connect the bottom end that two are filled out frame 22, the whole structural strength of gate flap 2 can be improved in this way；At this time below ground sill 3
It is further provided with sinking chamber 5, corresponding connecting cross beam 23 is accommodated by sinking chamber 5, and allow connecting cross beam 23 in sinking chamber 5
It inside moves up and down, and can further preferably be arranged after sinking chamber 5 is connected to the lower counterbore 4 of two sides and form whole cavity knot
Structure.It on above structure, needs still to remain with certain thickness ground sill 3 above sinking chamber 5, just can avoid because sinking in this way
Chamber 5 is pierced by and is formed the groove structure of mutation from the bottom surface rock mass of runner 4, 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 each in the utility model
The inside of gate slot 1 is additionally provided with access path 7.It is specific then the size of gate slot 1 can be increased inside it, such as institute in attached drawing 3
Show, can be entered in this way by the access path 7 to carry out upkeep operation.
In addition, gate flap ontology 21 is further preferably arranged in the utility model and fills out for the ease of installing and overhauling disassembly
Frame 22 is detachably connected by bolt.Without loss of generality, when being provided with connecting cross beam 23, connecting cross beam 23 is filled out with corresponding
It can also be detachably connected by bolt between frame 22.
In addition, high water head plane gate structure described in the utility model is further referring to shown in attached drawing 1 and attached drawing 2
It further include lock chamber 8, mechanism for opening/closing 9, resigning chamber 10, sealing cover 11 and connector 12, the mechanism for opening/closing 9 is mounted in lock chamber 8,
The 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, in resigning chamber 10 and lock chamber 8
Junction 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,
Mechanism for opening/closing 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
, the mechanism for opening/closing 9 in the utility model 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
