Abstract

According to the present invention, an upward sealable nonmetal sluice comprises: a sluice plate which is attached to one surface of a sluice frame having a supporter on both sides in a longitudinal direction, and includes a sealing member for leakage prevention along a circumference of an opening part formed to move water or treatment water, and a first flat bar of a prescribed length in a longitudinal direction of a surface with the sealing member; and a door plate slidably installed on a guide unit of the sluice frame, wherein an upper end thereof is connected to a drive unit to ascend and descend by drive of the drive unit and open and close the opening part of the sluice plate. A first roller is arranged on one surface of the door plate to move along the first flat bar of the sluice plate. The first flat bar guiding a movement of the first roller has an inclined surface maintaining a prescribed thickness and having a thickness becoming gradually smaller on an upper end thereof to allow the first roller to ascend onto the first flat bar along the inclined surface of the first flat bar when the door plate descends and separate the door plate from the sealing member by the thickness of the first flat bar to move the door plate while the door plate does not come in contact with the sealing member to open the sluice. When the door plate ascends, the door plate is separated from the sealing member by the thickness of the flat bar to move while the door plate does not come in contact with the sealing member. When the first roller descends below the first flat bar along the inclined surface of the flat bar, the door plate is tightly attached to the sealing member to close the sluice.

Description

Ascent-Type HDPE Sluice Upward Closed Non-

The present invention relates to an upwardly closed nonmetallic sluice gate, and more particularly, to an upwardly closed nonmetallic sluice gate which is installed to manage raw water flowing in each process in a water purification plant, a sewage treatment plant, a wastewater treatment plant, .

It is well known that a water gate is installed in the drain of the embankment such as a reservoir built for the purpose of storing water in general. The water gate is usually installed as a movable type, and it controls the reservoir water reservoir by storing or discharging water.

In addition, the water gate is installed in a sewage treatment plant, a wastewater treatment plant, a pumping station, a water purification plant, etc. so that the flow rate can be appropriately adjusted and the treatment water installed in the inflow portion of the treatment space .

Such a conventional water gate is composed of a water gate frame which is installed on a ground or a concrete structure of a waterway or the like and has longitudinal guide portions on both sides thereof and an opening which is fixed to one side of the water gate frame and through which water or treatment water moves, A frame plate provided with a sealing member, a door plate which is inserted into the guide portion of the water gate frame and is raised and lowered, and a driving portion which raises and lowers the door plate.

Here, the door plate is moved up and down according to the driving of the driving unit to open and close the opening of the frame sheet, and when the door plate is brought into contact with the surface of the door plate which is raised and lowered, Thereby preventing leakage through the pipe.

However, when the door plate is lifted or lowered in the process of opening and closing the water door, frictional force is generated between the door plate and the sealing member, and the sealing member is worn or torn due to friction with the door plate , Whereby water or process water is leaked and the life of the sealing member is shortened.

In addition, it is necessary to consider the installation direction of hydrofoil because hydrostatic pressure and reverse water pressure are operated according to the direction of the raw water because the maintenance cost is high since the inflow of raw water from each process is blocked from time to time, It is installed in accordance with the process direction of the civil engineering structure while neglecting the direction of reverse hydraulic pressure. The method of ignoring the directional hydraulic pressure disadvantageously hinders the operation of the watercraft.

In addition, since the door plate is made of cast iron, the weight of the door plate is increased, so that the driving force of the driving unit is increased to raise and lower the door plate, and the door plate can not be installed in a corrosive environment such as a sewage treatment plant, There is a problem that the corrosion progresses rapidly and the service life is shortened even when installed.
