Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing device for the undulating gate and the main sluice gate of a sluice gate having an undulating gate at its upper part.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sluice gate with an undulating gate having a common opening/closing device that can independently open and close the undulating gate and the main sluice gate using a simple opening/closing device.

To explain this invention with reference to the drawings, the embodiment shown in FIGS. 1 and 2 is a water gate in which the main water gate 1 and the undulating gate 2 are opened and closed using only wire ropes.

A hanging shaft 3 is rotatably supported on the upper part of the main water gate 1, and an operating device 4 such as an arm is fixed to this.

The aforementioned operating device 4 is an arm in this embodiment, and rope sheeps 5 and 5' are rotatably attached to both ends of the arm, and a wire rope 7°7' hung thereon is a rope sheep q for operating the water gate. , 9 to two opening/closing machines 10, 10' which are winding drums.

The fixed end 11 of said wire rope 7,7' is fixed to the sluice dam.

A drum serving as the opening/closing machine 10, 10' is provided for each rope 7.7', is driven by a prime mover, and has the same drum diameter.

When it is desired to open (overturn) the undulating gate 2, the right drum is rotated to the left (counterclockwise rotation), and at the same time, the left drum is also synchronously rotated to the left.

In this way, the wire ropes 7 and T', which are hung around the rope sheeps 5 and 9, move in the direction of the arrow in the figure, respectively, and the movement of these ropes is controlled by operating the operating device 4. Rotate to the left (clockwise).

This arm operating device 4 is fixed to the shaft 3 of the hoisting gate 2, so that the hoisting gate 2 can be controlled by the drum opening/closing machine 10,
It will be opened (overturned) according to the rotation of 10'.

If it is desired to close (erect) the undulating gate 2, the operation that is completely opposite to the above may be performed.

In this case, the wire rope will move in the direction of the dotted arrow a.

Furthermore, when it is desired to raise the main water gate door 1, the drum opening/closing machine 10 is rotated clockwise and the drum opening/closing machine 10' is rotated counterclockwise.

In this way, the wire ropes 7, 7' each move in the direction of arrow C in the figure, and the main water gate 1 therefore rises.

Furthermore, if the operation is completely reversed to that described above, the main water gate door 1 will be lowered.

In addition, this opening/closing mechanism allows the main water gate door 1 to be raised and lowered at any desired opening degree of the undulation gate 2.
It also has the feature that the opening degree of the undulation gate can be maintained even if any external force is applied to the undulation gate 2 from above or downstream.

In this way, the shaft 3 serves both as a suspension shaft for raising and lowering the main water gate door 1 and as a rotation shaft for rotating the undulating gate 2.

In the embodiment shown in FIGS. 3 and 4, essentially:
This is the same as in the previous embodiment, and the operating device 4 is a sprocket instead of an arm, and this is connected to the main water gate 1 and the undulation gate 2 by opening/closing machines 10 and 10' using sprockets via a chain 8. Open and close separately.

When the sprocket opening/closing devices 10 and 10' are rotated clockwise, the chain 8, which is hooked to each sprocket on the dam side and the main water gate 1 side, moves in the direction of the dotted arrow a in the figure, as shown in the figure. The sprocket operating device 4 and shaft 3 are rotated to the left, and the undulating gate 2 is closed (erected).

Conversely, when the sprocket switches 10 and 10' are rotated to the left, the chino 8 moves in the direction of the arrow in the figure, opening (lowering) the undulating gate 2.

Also, when the sprocket switch 10 is rotated clockwise and the sprocket switch 10' is rotated counterclockwise, the chain 8 moves in the direction of arrow C in the figure, and the main water gate 1 moves along with the undulating gate 2.
Second ascension.

If you want to lower this water gate door, just do the opposite operation to the above.

The embodiments shown in FIGS. 5 and 6 are a compromise between the two embodiments described above, in which wire ropes 7, 7' and chinos 8 are used together.

That is, the operating device 4 is a sprocket operating device 4' fixed to the rotating shaft 3, and rope sheeps 5, 5 are provided at both ends of the chain 8, and a wire rope 7.7' is placed on this, and this is installed on the dam. It is wound separately around the switches 10 and 10' using winding drums.

The operations are the same as described above, so a description thereof will be omitted.

The switches io and io' may be driven by separate prime movers, or may be driven separately by a single prime mover using a power transmission mechanism.

The water gate with an undulating gate according to the present invention has a suspension shaft 3 provided at the upper part of the main water gate 1 for raising and lowering the gate body, which also serves as a rotating shaft for opening and closing the undulating gate 2. A simple operating device 4, such as an arm, a rope sheep, or a sprocket, is selected and attached to the shaft 3, and this is connected to two opening/closing machines 10, 10' installed on the water gate dam via a rope or chain. It was connected.

Thereby, the opening/closing machines io and io' are rotated in the same direction in the same direction.

Or by making the same rotation in opposite directions.

It can be operated either to open and close the main water gate door 1 or to open and close the undulation gate.

Therefore, the two gates, the main water gate 1 and the undulating gate 2, which are parent and child gates, can be operated using one opening/closing device.

Since the two switchgears 10° and 10' bear half of the load each, this switchgear can be made with small-capacity equipment.

Therefore, the main water gate 1 and the undulating gate 2 can be reliably opened and closed with an extremely simple structure.
