DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

1 shows an embodiment of a flushing gate 10 according to the present invention.

Referring to FIG. 1, a flushing gate 10 for flushing a water channel by discharge of water stored in a cleaning tank includes a gate frame 11 for storing water; A gate door (12) coupled to the gate frame (11) so as to be openable and closable while forming a contact surface; And sealing means (171, 172) formed on at least part of the contact surface, said sealing means (171, 172) forming a curved sealing surface extending along the contact surface.

The flushing gate 10 may be installed in a facility or apparatus for cleaning a waterway in which water containing various foreign substances or dirt, such as an overflow reservoir, a canal waterway, A cleaning system may be separately formed for cleaning the water channel, and a water storage dam or a water storage tank may be disposed. The cleaning system can have a structure that allows a certain level of water to be stored and a structure in which the stored water can be discharged at a time. And the flushing gate 10, which forms part of the cleaning system, can function as an outlet for the release of the stored water.

The gate frame 11 can be a frame forming the outlet of a water storage dam or a water storage tank and can be made in a structure protruding from a dam or tank for the discharge of water. For example, the gate frame 11 may be box-shaped and may form part of a dam or tank. The gate frame 11 may have a passage function for discharging the stored water, and the gate door 12 may be coupled to the gate frame 11.

The gate door 12 can be formed in a plate shape and can be coupled to the gate frame 11, for example, by a hinge fastening unit 16 or similar means. The gate frame 11 has a box shape with both sides opened, and the gate door 12 can store or discharge water by opening and closing one side of the gate. Thus, the gate door 12 can have a door function that can be opened or closed for storing or releasing stored water. For example, the upper portion of the gate door 12 in the shape of a square plate can be coupled to the gate frame 11 by the hinge fastening unit 16. The lower portion of the hinge fastening unit 16 is rotated to open and close the gate frame 11 while the hinge fastening unit 16 is engaged. The closed state of the gate door 12 can be maintained by the engagement of the adjustment rollers 14a, 14b, 14n and the opening and closing hook 15. [ The regulating rollers 14a, 14b and 14n and the opening and closing hook 15 are operated for the purpose of cleaning so that the lower part of the gate door 12 is rotated and the gate frame 11 can be opened, The flow path can be cleaned as it is discharged.

The gate frame 11 is held in a fixed state and the gate door 12 can be operated in such a manner as to open and close one side of the gate frame 11. [ Thereafter, the gate frame 11 and the gate door 12 form a contact surface. For example, the outer peripheral portion of the gate frame 11 and the inner peripheral surface of the gate door 12 may be in contact with each other . The water is stored in the discharge induction portion WS of the gate frame 11 while the water is stored and the storage tank can be located at a relatively higher position than the discharge inducing portion WS. Therefore, a large water pressure can be applied to the gate door 12 in a state where water is stored. Whereby water stored in the discharge inducing portion WS through the contact surface can leak.

According to one embodiment of the invention, sealing means (171, 172) can be arranged on at least part of the contact surface and the sealing means (171, 172) form a curved sealing surface extending along the contact surface. The sealing means 171 and 172 may be formed on the outer portion of the gate frame 11 or on the inner portion of the gate door 12 and the gate frame 11 and the gate door 12 may be formed by sealing means 171 and 172 ). For example, the sealing means 171 and 172 can be installed at positions corresponding to each other of the gate frame 11 and the gate door 12, and contact with each other in a state in which the gate door 12 is closed to form a watertight structure Thereby preventing leakage of water through the contact surface. The sealing means 171 and 172 which are in contact with each other can form a curved sealing surface. For example, the sealing means 171 and 172 formed on the circumferential surface of the gate frame 11, It may have a curved shape. The sealing means 171 and 172 formed at corresponding positions of the gate door 12 may also have a bent shape in which mountains and valleys are continuously formed. In this structure, the sealing means 171 and 172 formed on the gate frame 11 and the gate door 12 can be formed such that the mountains and the valleys are staggered to be inserted and accommodated. Accordingly, the closed surface may have a curved shape in which mountains, crests, or similar shapes are continuously formed.

The sealing means 171 and 172 can be made of a material having elastic and hydrophobic properties and can be made of, for example, rubber, silicone, polypropylene, polypropylene or a mixture thereof, but is not limited thereto. The sealing means 171, 172 can also be made in a multi-sealing configuration. The multi-hermetic structure may be, for example, a double-sealed structure in which a direction perpendicular to the extending portion of the rim where the gate frame 11 and the gate door 12 are in contact with each other is formed. A sealing structure having various structures can be formed on the contact surface of the rim and is not limited to the illustrated embodiment.

A plurality of regulating rollers 14a, 14b and 14n may be arranged below the gate door 12. For example, a plurality of regulating rollers 14a , 14b, 14n may be disposed apart from each other at appropriate intervals. The sliding member 131 having the opening and closing hooks 15 engageable with the adjusting rollers 14a, 14b and 14n is provided on the gate frame 11 so as to be movable along the direction in which the adjusting rollers 14a, 14b and 14n are arranged. . A plurality of opening and closing hooks 15 may be disposed integrally with the sliding member 131 or detachable from the sliding member 131 at positions corresponding to the adjusting rollers 14a, 14b and 14n. The sliding member 131 can be moved along the width direction of the gate door 12 or the gate frame 11 by the operation of the operating cylinder 13. [ When the opening and closing hook 15 is engaged with the adjustment rollers 14a, 14b and 14n while the sliding member 131 is moved along the width direction of the gate frame 11 in accordance with the operation of the operating cylinder 13, Can be locked. When the water needs to be discharged for cleaning the water channel after the water is stored in such a state, the sliding member 131 is moved in the direction opposite to the engaging direction along the width direction by the operation of the operating cylinder 13, The engagement of the adjustment roller 15 and the adjustment roller 14a, 14b, 14n can be released. Accordingly, the water can be released as the gate door 12 is opened by the pressure of the water.
