Description

Automatic water gate opening and closing device

The present invention relates to an automatic sluice opening and closing device, and more particularly, to an automatic sluice opening and closing device capable of easily eliminating the interference of the closing of the water gate by the foreign matter remaining in the outlet.

The automatic water gate opening and closing device is installed in the river basin or dike, and when the freshwater level is higher than the set height, it automatically opens the discharge port by the fresh water pressure. It is supposed to be possible.

The general automatic gate opening and closing device is mainly applied to the structure that the plate-shaped gate can be opened and closed by rotating the outlet.

The automatic sluice opening and closing device is moved in the discharge direction of the effluent while the foreign body, including wood chips, gravel, etc., flows along with the water discharged through the drain when the sluice is opened. By the way, various foreign matters flowing with water often remain in the closed position of the gate by its weight. In this case, as the fresh water level is lowered and the gate is moved to the closed position due to its own weight, foreign matter remaining on the bottom surface corresponding to the closed position of the gate does not reach the position where the gate is closed to the outlet and leaks. There is a problem that can be.

The task of removing debris that obstructs the closure of the floodgate is very difficult and dangerous because of the effluent flowing quickly through the gap.

In order to improve this problem, Korean Laid-Open Patent Publication No. 1999-0073766 discloses an auxiliary gate opening and closing device having two barrier plates that can be rotated relative to the top and bottom surfaces of an outlet.

However, the auxiliary gate opening and closing device is inconvenient in use because the operator has to adjust the opening and closing direction by using the driving means independently of each level, regardless of the water level, and the second blocking plate has a bottom surface of the outlet and a sealing function In addition, since there is a need to rotate about the bottom surface of the discharge port, there is a problem that may not be rotated when foreign matter such as sand is caught between the second blocking plate and the bottom surface.

The present invention has been made in order to improve the above problems, it is structured to easily remove the deposits remaining in the closed position of the water gate to provide an automatic water gate opening and closing device that can be made smoothly to open and close the gate. There is a purpose.
