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.

Here, the hydrologic frame 100 is fixed to a ground, a concrete structure, or the like of a waterway to form a watercraft frame.

2, the supporters 110 provided at both sides of the water gate 100 serve to guide the door plate 300 and include a gap adjusting bolt 120 (not shown) coupled to the water gate 100, And the interval between the door plate 300 and the door plate 300 is adjusted by adjusting the interval of the interval adjusting bolts 120.

The water level plate 200 is formed with an opening 210 through which water, treatment water or the like is moved, a groove is formed along the periphery of the opening 210, and a sealing member 220 is forcedly inserted into the processed groove .

Here, as shown in FIGS. 3A and 3B, the sealing member 220 is provided with air spaces in which air is contained, that is, independent air bags 221 at regular intervals. At this time, the joint part of the sealing member is sealed with an adhesive by inserting a circular rod into the air space inside. That is, a certain air bag is formed in the interior of the sealing member 220 to provide a restoring force when pressed, thereby improving buffering and airtightness.

In addition, the water level plate 200 is provided with a first flat bar 230 having a predetermined length along the longitudinal direction of the surface provided with the sealing member 220.

The first flat bar 230 has a shape in which the thickness of the first flat bar 230 is gradually decreased at the upper end portion to form a sloped surface. The plurality of first flat bars 230 may be provided at predetermined intervals according to the length of the water level plate 200.

The door plate 300 is slidably mounted on the guide formed by the supporter of the water gate 100 and the door plate 300 And a driving unit 400 for raising and lowering the door plate 300 is connected to the upper end.

The door plate 300 includes a first roller 310 that contacts the first flat bar 230 of the hydrograph plate 200 and rolls on the first flat bar 230 when the door plate 300 is lifted or lowered, .
