Description

[Detailed description of the invention] (Industrial application field) The present invention is a side-opening waterway gate, and more specifically, it does not require a particularly large space and can be easily installed in any location and shape of the waterway cross section. The present invention also relates to a side-opening waterway gate that is easy to open and close.

(Prior Art) Water is increasingly used as a non-polluting energy source, and the effective use of waterways is becoming increasingly important.

Waterway gates are installed in such waterways, and are used to switch from one waterway intake to a wide variety of waterways, or to close off individual waterways, such as: It functions exactly the same as a stop valve installed in the middle of a pipe that can be opened and closed freely.

FIGS. 5 and 6 are diagrams showing conventional examples of waterway gates.

FIG. 5 shows a sliding gate, where 1 is a waterway and 21 is a partition plate. When water is flowing in the direction of arrow A in waterway 1, insert the partition plate 2 into the flow of waterway 1 and slide it in the direction of arrow B to open the gate, and slide it in the direction of arrow C to open the gate. The gate is about to close.

Figure 6 shows a swing-type gate with a fifth
As in the case of the figure, 1 is a waterway, and 21 is a partition plate. When water is flowing in the water channel 1 in the direction of arrow A, swinging one end of the partition plate 21 as the center and swinging it in the direction of arrow B will open the gate, and swinging it in the direction of arrow C will open the gate. is starting to close.

(Problems to be solved by the invention) In the waterway gate as described above, a large amount of space is required to partition the waterway 1 when the waterway 1 is buried underground. Further, when the cross-sectional shape of the water channel 1 is other than rectangular, it is difficult to attach the partition plate 21.

Furthermore, since the conventional waterway gate opens and closes by inserting the partition plate 21 into the waterway 1 and rotating it within the waterway 1, a large amount of force is required to open and close the gate.

The purpose of the present invention is to provide a side-opening waterway gate that does not require a particularly large space, can be easily installed in any location and in any waterway cross-sectional shape, and is easy to open and close.

(Means for Solving the Problems) In order to achieve the above object, the horizontally opening waterway gate according to the present invention includes a fixed frame fixed to the outer periphery of the waterway cross section, and a fixed frame capable of closing the fixed frame in a watertight manner. A door plate rotatably provided on the frame, a concentration plate provided approximately in the center of the door plate that rotates and moves forward and backward with respect to the door plate, and a plurality of clamps each having one end freely supported by the concentration plate. Inclusive bar and
It consists of a receiving plate provided on the fixed frame to which the tightening bar is engaged and detached, and a tightening bar guide provided on the door plate and serving as a free fulcrum upon which the tightening bar is inserted. 1 to bring it close to the door plate, the tightening bar is used as a lever with the receiving plate as a fulcrum and the tightening bar guide as a point of use to press the door plate against the fixed frame. closing the water channel, rotating the collecting plate in a second direction and moving it away from the door plate to release the lever action of the tightening bar and opening the waterway, and moving the collecting plate towards the second direction. The door plate is configured to be able to further rotate in the direction to detach the tightening bar from the receiving plate and open the door plate laterally.

(Example) The present invention will be described in detail below with reference to the drawings and the like.

Fig. 1 is a front view showing an embodiment of a horizontally opening waterway gate according to the present invention, Fig. 2 is a plan sectional view showing the gate of the embodiment, and Figs. 3 and 4 are gates of the embodiment. It is a figure for explaining the opening and closing mechanism used for.

In Figures 1 to 4, 1 is a water channel, 2 is a door plate, 3 is a tightening handle, 4 is a concentration plate, 5 is a tightening bar, 6 is a receiving plate, 7 is a tightening bar guide, 8 is a hinge Arm, 9 is hinge, 10 is stop valve, 11 is gasket, 12 is fixed frame,
13 is a support member, and 14 is a main screw.

As shown in FIG. 1, receiving plates 6 are fixed to the four corners of the fixed frame 12, and tightening bars 5 are inserted into each of the receiving plates 6. The tightening bar 5 is guided by a tightening bar guide 7 provided on the door 2, and its other end is gathered on the gathering plate 4.

As shown in FIG. 2, a fixed frame 12 is embedded in the water channel 1, and a support member 13 is planted in the fixed frame 12. A hinge arm 8 is attached to the support member 13 via a hinge 9, and the door plate 2 is attached to the hinge arm 8. The door plate 2 is for closing off the waterway 1, and a gasket 11 is provided between the door plate 2 and the inner frame 12 to maintain watertightness.

Next, the detailed structure of the opening/closing mechanism of the waterway gate according to the present invention and the opening/closing operation of the gate will be explained.

As shown in FIG. 3, one end of the tightening bar 5 is gathered by the collecting plate 4, and the other end is pushed into the receiving plate 6. The tightening bar 5 is guided by a tightening bar guide 7 provided on the door plate 2. A main screw 14 is screwed into the collecting plate 4, and the tip of the main screw 14 is in contact with the door plate 2.
A handle 3 is provided on the head. By rotating the handle 3, the concentrating plate 4 is moved in the direction of arrow A or B through the main screw 14.

When closing the waterway gate, the handle 3 is rotated to move the collecting plate 4 in the direction of arrow A in FIG. 3, and to move the tightening bar 5 to the position shown by the solid line in FIG. 3. At this time, tighten the bar guide 7.
is fixed to the door plate 2, so the tightening bar 5 rotates around the tightening bar guide 7.
Since the receiving plate 6 is fixed to the fixed frame 12, an upward force acts on the receiving plate 6, and the door plate 2 moves toward the fixed frame 12 due to the action of the lever. Therefore, the door plate 2 is pressed against the fixed frame 12 via the packing 11, and watertightness can be maintained.

When opening the waterway gate, by rotating the handle 3 in the opposite direction, the collecting plate 4 moves in the direction of arrow B in Figure 3, so the tightening bar 5 tightens in the opposite direction to when closing it. 3rd center around bar guide 7
It moves to the position shown by the two-dot chain line in FIG. 6, and the contact force with the receiving plate 6 is eliminated. At the same time, the packing 11 of the door plate 2 is no longer watertight, and the opening operation can be started.

Next, the operations required to open the door plate 2 laterally will be explained.

When the door plate 2 is closed, the tightening bar 5 is inserted into the receiving plate 6, so the door plate 2 cannot be opened or closed laterally by the hinge 9 as it is.

Therefore, by rotating the collecting plate 4 in the direction of arrow B in FIG. 4 using the handle 3, the free fulcrum within the collecting plate 4 is displaced to the position shown by the two-dot chain line. With this operation, the tightening bar 5 is pulled out and separated from the receiving plate 6 around the tightening bar guide 7. In this separated state, the door plate 2 can be opened laterally around the hinge 9.

The closing operation of the door plate 2 may be performed in the exact opposite direction to the opening operation.

(Effects of the invention) As explained in detail above, according to the invention,
It does not require a particularly large space and can be easily installed in any location and any waterway cross-sectional shape.

In addition, the opening and closing operations are easy, and the waterway can be completely blocked or simply opened.
