Description

[Detailed description of the invention] The present invention relates to an overturning weir installed on a river, etc., and is a water stopper installed to close the gap between a door body rotatably installed on the river bed and an upstream doorstop. A receiving material is provided inside the membrane to prevent the water-stopping membrane from being inserted into the gap.

A water-stop membrane is often installed to close the gap between a door stop and a door rotatably installed on a river bed. FIG. 5 shows a conventional overturning weir of this type, showing a door body 5a rotatably installed on the river bed.
In order to close the gap a between the door stop 5a and the upstream door stop 5a, a water stop film 5c is provided on the door stop 5b so as to protrude toward the door 5a. There was a drawback that water leakage was likely to occur due to getting caught in the lower part of 5a. Therefore, as shown in FIG. 6, a water stop film 6c that completely blocks the gap a is installed.
A structure that is attached to the door body 6a and the door stop 6b has been proposed, but in the case of such a structure, the water-stop film 6c has a width that is wide enough to allow the door body 6a to fall. Therefore, as shown in the figure, when the door body 6a rotates, the water stop film 6c is inserted between the door body 6b and the door stop 6b, and the water stop film 6a
The problem was that it was damaged and caused water leakage.

Therefore, the present invention has been made for the purpose of providing an overturning weir that eliminates the drawbacks of the conventional ones, and includes a receiving material that covers the above-mentioned gap inside the water-stopping membrane. This makes it possible to reliably prevent the water stop film from being caught between the door body and the door stop.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show the overturning weir in an upright state, and 1 is a door body, which is rotatably attached to a pedestal 2 installed on the river bed via a pin 3. Reference numeral 4 denotes a water-stop film formed of a material with water impermeability and flexibility, such as rubber, and its upper end is located at the lower part of the upstream side of the door body 1, and its lower end is located at the river bed on the upstream side of the door body 1. The door stop 5 is mounted on a door stop 5 with bolts and nuts 6 to ensure sufficient watertightness. As shown in Fig. 2, the water-stop film 4
is attached to the entire width of the door body 1 in the river width direction, and its width is provided with sufficient margin to allow the door body 1 to fall over.

Reference numeral 7 denotes a plate-shaped receiving member disposed inside the water-stop membrane 4, which is rotatably supported via pins 8 on base plates 9, 9 installed on the door stop 5. The upper end, which is a free end, contacts the upstream side surface of the door body 1 and covers the gap a between the lower part of the door body 1 and the doorstop 5.

This overturning weir consists of the above-mentioned configuration, with the door body 1
When the support member 7 is laid down, the receiving member 7 is also rotated and laid down around the pin 8 while its upper end is in contact with the door body 1 (see Fig. 3). Even in this state, the gap a is covered with the receiving material 7. In this way, since the gap a is always covered with the receiving material 7, the water-stop film 4 does not enter the gap a and become trapped.

FIG. 4 shows another embodiment of the present invention, in which the upper end of the receiving member 10 is rotatably attached to the side surface of the door body 1 via a pin 11, and the upper end is a free end. The lower end abuts on the doorstop 5 and covers the gap a. In this configuration, as the door body 1 rotates, the receiving material 10 rotates around the pin 11 while its lower end is in contact with the door stop 5 and constantly closes the gap a, so that the water-stop film 4 is sandwiched in the gap a. I don't want to run the risk of being swallowed.

The present invention can be further modified in various ways,
For example, the receiving material may be a bar-shaped body instead of a plate-shaped body, in short, it does not inhibit the rotation of the door body 1, and it can reliably prevent the water-stop film 4 from being inserted into the gap a. It may be of any shape or structure as long as it is a material.

As explained above, the overturning weir according to the present invention has a water-stopping membrane attached to the upstream side of the door rotatably installed on the riverbed and the doorstop installed on the riverbed upstream of the door. In addition, since the receiving material covering the gap between the lower part of the door body and the door stop is rotatably disposed on the door body or the door stop, the water-stop film is sandwiched therein. It will not be damaged and its watertightness will be compromised.
