Rotate with described second straight connecting rod one end and be connected, the other end of second straight connecting rod is rotated with gate upper end and is connected, the lock
Door lower end is rotated with the 3rd support base and is connected, and the slewing area of the gate is 0-60 °, and ball float floats, and V-arrangement link rotatable is certain
Angle, so as to drive the first straight connecting rod, triangular oscillating and the second straight connecting rod to rotate, and then drive gate to rotate.
Preferably, also including counterweight, the counterweight is placed on the side be connected with ball float on V-arrangement connecting rod.
Preferably, the V-arrangement connecting rod includes left end connecting rod and right-hand member connecting rod, the left end connecting rod and the be in folder of right-hand member connecting rod
Angle is 125-130 °, and left end length of connecting rod 800-900mm, right-hand member length of connecting rod 1200-1300mm.
Preferably, the length of first straight connecting rod is 400-500mm, and the length of second straight connecting rod is 380-
450mm。
This utility model beneficial effect is:This utility model effectively solving small hydropower station only relies on waterpower to be completed flood discharge and leads
Chute gate automatic open close function, while ensureing that gate is slowly opened, reduces release floodwatering flow speed, the more preferably peace of protection irrigated farmland
Entirely.The mechanism is safe and reliable, and simple structure is with low cost, facilitates handy.

Specific embodiment
In conjunction with the accompanying drawings and embodiments this utility model is described further.
A kind of automatic open close gate mechanism, including ball float, V-arrangement connecting rod, the first straight connecting rod, triangular oscillating and second be direct-connected
Bar, the V-arrangement connecting rod are rotated in the first support base and are connected, and the vertical height of the first support base fixed position is higher than gate
Height, the connection of described V-arrangement connecting rod one end swims in the ball float on the water surface, and the other end and described first straight connecting rod one end rotate and connect
Connect, the one jiao of rotation of the first straight connecting rod other end and the triangular oscillating is connected, another angle of the triangular oscillating and fixation
The second support base rotate connection, the third angle of triangular oscillating and described second straight connecting rod one end rotate and are connected, and described second is straight
The other end of connecting rod and gate upper end rotate and be connecteds, and the gate lower end is connected with the rotation of the 3rd support base, the gate turn
Dynamic scope is 0-60 °, and ball float floats, the certain angle of V-arrangement link rotatable, so as to drive the first straight connecting rod, triangular oscillating and the
Two straight connecting rods are rotated, and then drive gate to rotate.
As shown in figure 1, a kind of automatic open close gate mechanism, including gate, fulcrum bearing, bearing pin, straight connecting rod, V-arrangement connecting rod, three
Angle swing bar, counterweight, ball float, the 3rd fulcrum bearing 17 being connected with gate are mounted at the dam ground level of flood discharge guiding gutter entrance, with
The second fulcrum bearing 11 that triangular oscillating 6 is connected is arranged on flood discharge guiding gutter bottom surface with a slope, vertically below the 3rd
Bearing 200mm, at the 3rd fulcrum bearing 586mm of horizontal direction distance, the first fulcrum bearing being connected with V-arrangement connecting rod 3 is arranged on dam
On the steelframe of top, vertical direction is higher than the 3rd fulcrum bearing 725mm, at the 3rd fulcrum bearing 300mm of horizontal direction distance, gate 15
It is highly 2 times of safe power generation warning line height, 15 upper end of gate connects one end of the second straight connecting rod 13 by bearing pin 4, the
The other end of two straight connecting rods 13 is coupled an angle of triangular oscillating 6 by bearing pin 4, and the inferior horn of triangular oscillating 6 passes through bearing pin 4 and the
Two fulcrum bearings 11 are connected, and the upper angle of triangular oscillating 6 is connected with one end of the first straight connecting rod 8 by bearing pin 4, the first straight connecting rod 8
The other end is connected with one end of V-arrangement connecting rod 3 by bearing pin 4, and the other end and the ball float of V-arrangement connecting rod 3 are connected firmly, and V-arrangement connecting rod 3 is near floating
1 one end of ball is equipped with counterweight 2.
In the present embodiment, the V-arrangement connecting rod includes left end connecting rod and right-hand member connecting rod, the left end connecting rod and right-hand member connecting rod institute
It is 126 ° in angle, and left end length of connecting rod 845mm, right-hand member length of connecting rod 1250mm;The length of first straight connecting rod is 445mm,
