KR-102963108-B1 - Cylindrical movable weir with bridge functionality

Abstract

The present invention relates to a movable weir that controls the water level of a waterway while rotating. A cylindrical movable weir having a bridge function according to an embodiment of the present invention comprises a cylindrical weir member that controls the water level by opening and closing a waterway while rotating around a central rotation axis, and a movable mechanism that rotates the cylindrical weir member. The cylindrical weir member includes a waterway blocking part formed within a preset angle range with respect to the rotation axis of the cylindrical weir member to seal the waterway so that it reaches a full water level, and a flat waterway bridge part that is positioned in an inverted position with respect to the waterway blocking part and is exposed to the outside to cross the waterway when the cylindrical weir member is rotated to open the waterway.

1. A cylindrical movable beam having a bridge function comprising a cylindrical beam member that rotates around a central pivot axis to open and close a waterway to regulate the water level, and a movable mechanism that rotates the cylindrical beam member. The above cylindrical member is A channel blocking member formed within a preset angle range with respect to the rotation axis of the above-mentioned cylindrical member to seal the channel to the maximum water level, A flat waterway bridge section exposed to the outside to cross the waterway when the cylindrical beam member is rotated to open the waterway by being positioned in an inverted position relative to the above-mentioned waterway blocking section, and A cylindrical movable beam having a bridge function, characterized by including a concave foreign matter groove that accommodates foreign matter and is located in the opposite direction to the channel blocking member while the channel blocking member is blocking the channel, to handle foreign matter that interferes with the rotation of the cylindrical beam member.
2. In paragraph 1, The above waterway bridge section A cylindrical movable beam having a bridge function, characterized by including a stepping protrusion that protrudes higher than the low water level of the waterway from the waterway bridge section to prevent getting wet when crossing the waterway.
3. delete
4. In paragraph 1, The above-mentioned channel blocking part A cylindrical movable weir having a bridge function, characterized by including a fish passage space formed in the channel blocking part for fish to stay in, so as to allow fish to move while maintaining the full water level of the channel even when the cylindrical weir member is reciprocated.

Description

Cylindrical movable weir with bridge functionality The present invention relates to a movable weir that controls the water level of a waterway while rotating. Generally, weirs are installed in waterways to regulate water levels; weirs block the waterway in the form of plates and open or close the waterway by lifting or rotating the weir. Since plate-shaped weirs have difficulty withstanding high water pressure, a "water-stopping device for movable weirs" was previously disclosed in Korean Registered Patent Publication No. 10-1006878 (published Jan. 12, 2011). The aforementioned conventional movable weir sealing device was able to open and close a waterway with relatively high water pressure by supporting the part blocking the waterway through an arc-shaped surface. However, conventional movable weir gates had the problem that when the waterway was opened, it was difficult to cross the weir, requiring the installation of a bridge to cross the waterway, and foreign matter could easily enter, hindering the weir's rotation and causing it to malfunction. In addition, when the waterway was closed, the movement of fish was difficult, leading to the problem of damage to the fish ecosystem. FIG. 1 is a perspective view illustrating a cylindrical movable beam having a bridge function according to an embodiment of the present invention, in a state where the waterway is closed by a waterway blocking part. FIG. 2 is a perspective view illustrating a cylindrical movable beam having a bridge function according to an embodiment of the present invention, in which the waterway is opened and the waterway bridge section is exposed to the outside. FIG. 3 is a closed state of the waterway of a cylindrical movable beam having a bridge function according to an embodiment of the present invention, where (a) is a side cross-sectional view and (b) is a plan view. FIG. 4 is a state in which the waterway of a cylindrical movable beam having a bridge function according to an embodiment of the present invention is opened, where (a) is a side cross-sectional view and (b) is a plan view. FIG. 5 is a perspective view illustrating a modified example of a channel blocking part constituting a cylindrical movable beam having a bridge function according to an embodiment of the present invention. FIG. 6 is a side cross-sectional view illustrating a modified example of a channel blocking part constituting a cylindrical movable weir having a bridge function according to an embodiment of the present invention, wherein (a) shows a state in which a fishway space is located on the upstream side and (b) shows a state in which a fishway space is located on the downstream side. Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. A cylindrical movable beam (100) having a bridge function according to an embodiment of the present invention is installed across a waterway and can maintain a low water level by opening the waterway or maintain a high water level by closing the waterway. Here, a waterway refers to a place where water flows artificially or naturally, such as a river or embankment. As shown in FIGS. 1 to 4, the rotary movable beam can maintain a low water level by opening the waterway as the cylindrical beam member (120) rotates, or maintain a high water level by closing the waterway. The cylindrical member (120) can be formed in a cylindrical shape, and the cylindrical member (120) can rotate around a rotation axis (121) located at the center. The cylindrical member (120) can be rotated by a movable mechanism, and the movable mechanism may be implemented as a cylinder operated by hydraulic or pneumatic pressure or a drive motor that transmits power by a gear connection or a belt or chain. The cylindrical beam member (120) may be configured with a channel blocking part (123) for opening and closing the channel, a foreign matter groove part (125) for receiving foreign matter to prevent foreign matter from getting caught when rotating, and a channel bridge part (127) for crossing the channel while the channel is open. When the cylindrical beam member (120) is viewed from the side, the channel blocking part (123) can be located at an angle of approximately 0° to 90° with respect to the rotation axis (121), the foreign matter groove part (125) can be located at an angle of approximately 90° to 180°, and the channel bridge part (127) can be located at an angle of approximately 180° to 360°. The channel blocking part (123) can raise the water level to full water level by closing the upstream side of the channel to increase the amount of fresh water. Since the channel blocking part (123) is shaped like a fan and becomes thicker towards the bottom, the resistance to water pressure increasing with depth of the channel can be relatively increased. As illustrated in FIGS. 5 and 6, as a modified example of the channel blocking part (123), the channel blocking part (123) may have a fish passage space (123
