DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In connection with the present invention, a very large number of water gates are installed in a wide river. When such a large number of gates are installed at the same time, the watertightness between the gates is very important. The present invention relates to a watertight portion for maintaining watertightness between water gates.

For convenience of explanation, the termination beam, which is a subordinate configuration of the claim, will be described first, and a description of the watertight portion, which is an independent term configuration, will be described later.

The water gate 10 according to an embodiment of the present invention is configured such that both side portions of the water gate body in the form of a plate are rotatably installed and the space portion between the water gate body and the floor is blocked And may be installed as a support means for supporting the hydrology main body on the drainage side close to the hydrology main body. When the water level in the lower water level rises, the upper side of the water level main body rotates to the drain side to drain water, and when the water level falls, the upper side of the water level main body rotates to the water level side, can do.

These water gates (10) can be automatically adjusted to maintain the water level on the water side constantly by installing the water gauge (10) on the water channel of the reservoir or river.

As shown in Figures 1-3, the gate 10 may include an end beam 30.

The longitudinal beams 30 may be disposed along the height direction of the water gate 10 on the left and right sides with respect to the direction in which the water gates 10 are arranged. That is, the water gate 10 may be disposed at one side or the other side perpendicular to the front surface 2 receiving the water pressure. Also, the end beam 30 may be made of a metal material.

The longitudinal beam 30 serves to improve the durability of the water gate 10 and to connect the water gate 10 and the watertight portion 20 so that the watertight portion 20 to be described later can be firmly fixed to the water gate 10 do.

The longitudinal beam 30 has a cross section in the shape of alphabet I with respect to the transverse direction of the river in which the water gate 10 is installed and can be connected to the left and right along the height direction of the water gate 10, respectively. The longitudinal beam 30 can be joined to the left and right sides of the front surface 2 of the water gate 10 which is the surface where the water gate 10 receives water pressure, that is, the surface where the water gate 10 blocks water.

More specifically, the longitudinal beam 30 is formed in the shape of a plate having a height corresponding to the height of the water gate 10 and extends in the same direction as the transverse direction of the river, And a head 31 joined to the head 31.

The longitudinal beam 30 is formed in a plate shape having a width corresponding to the thickness of the water gate 10 and a height corresponding to the height of the water gate 10 and is formed in a direction perpendicular to the transverse direction of the river, And an abdomen plate 32 joined to a vertical surface 1 perpendicular to the front surface of the water gate 10 in the same direction.

The longitudinal beam 30 is formed to have the same size as the head 31 and is formed in the same direction as the transverse direction of the stream 31 so that the water gate 10 is located on the rear surface 3 of the water gate 10, And a bottom portion 33 joined to the bottom portion.

In the present invention, the end beam 30 is applied as an end beam of an alphabet I shape, but may also be formed as an end beam of an alphabet H shape. Therefore, the shape of the end beam 30 is not limited thereto, and may be formed in various shapes.

The longitudinal beam 30 according to an embodiment of the present invention is described as being separated from the skin plate 40 which will be described later forming the front surface 2 of the water gate 10, .

However, the vertical surface 1, the front surface 2 and the rear surface 3 shown in Fig. 3 and described above are not necessarily physically existing planes but are used to specify the conceptual configuration of the water gate 10.

1 to 3, the water gate 10 according to an embodiment of the present invention includes a watertight portion 20.

The watertight portion 20 can be installed for the watertightness of the water gate 10, which functions as a water storage and drainage, that is, regulates the water level of the river. At this time, the water gate 10 may be a plurality of water gates arranged across a wide river, or may be a water gate installed between a structure installed in a river and a structure.

In connection with this, the water gate 10 is divided into a rotary type, an elevation type, a conductive type, and the like depending on its operating principle, that is, the opening and closing method. The rotary type is a method of opening and closing the water gate by turning around a specific axis. The elevating type lifts the water gate out of the river and closes it again. The conduction type can completely turn the water gate to the bottom of the river, The angle between the bottoms is adjusted to adjust the flow rate.

Therefore, the water gate 10 of the present invention can be any one of the above-mentioned rotary type, elevation type, and conduction type.

This watertight portion 20 can be joined to the baffle plate 32 of the end beam 30. The watertight portion 20 may be formed of a thin metal plate and may extend a long length along the height direction of the water gate 10.

The watertight portion 20 may be formed of a thin metal plate having a thickness of 2 mm to 3 mm. In particular, for example, stainless steel or a metal having low corrosion resistance such as a coated steel sheet. The watertight portion 20 has elasticity by its shape and can be elastically deformed by an external force.

1 to 3, the watertight portion 20 may include a rounded portion 21. The rounding portion 21 is convexly protruded outwardly from the front end of the watertight portion 20, that is, between one end on the front face 2 side opposite to the longitudinal direction of the watertight portion 20 and the other opposite end, And a rounded portion 21 is formed.

The rounded portion 21 is formed uniformly throughout the longitudinal direction of the watertight portion 20, so that the watertight portion 20 can have the same cross-sectional surface over the entire lengthwise direction.

The rounding portion 21 may be formed in a plate shape having a curved shape curved convexly toward the outside of the baffle plate 32. [

Therefore, when the rounding portion 21 comes into contact with the metal plate 71 or the structure to be described later, which is joined to the mating door 10, the rounding portion 21 is elastically deformed by the external force due to the contact, 10 and the structure.

More specifically, the cross section of the rounding portion 21 can be formed so that the point at which the rounding portion 21 rises most from the baffle plate 32 is biased toward the front surface 2 rather than the rear surface 3.

Accordingly, in the front end direction of the watertight portion 20, a more urgent slope can be formed as compared with the backward direction about the highest point of the rounding portion 21. [

On the other hand, in the front end direction of the watertight portion 20, the watertight portion 20 surrounds the head portion 31 of the above-described longitudinal beam 30 while forming a sharp inclination from the highest point of the rounded portion 21, The front end portions of the portions 20 may be arranged in a line parallel to the front surface 2 described above. At this time, the front end of the watertight portion 20 is formed as a free end portion 21a that is not fixed to the water gate 10, so that when the rounded portion 21 is elastically deformed by an external force applied to the rounded portion 21, And can be configured to be movable within a certain range. In addition, the watertight portion 20 is formed to have a relatively gentle slope in the rearward direction about the highest point of the rounded portion 21 and to approach the vertical surface formed on the bending plate 32 of the longitudinal beam 30, (20) is bonded to the bumper plate (32).

At this time, the watertight portion 20 can be fixed by connecting the rear end of the watertight portion 20, which is in close contact with the abdomen plate 32, with the end beam 30 with the screw 60.

1 to 3, the water gate 10 may further include a skin plate 40. The skin plate 40 is formed in a plate shape and can form the front surface 2 of the water gate 10 in the same direction as the transverse direction of the river. The skin plate 40 enhances the durability of the water gate 10 to protect the water gate, resist water pressure, and block the flow of the water.

One or more transverse beams (not shown) arranged to be perpendicular to the longitudinal beam 30 may be joined between the longitudinal beams 30 disposed on the right and left sides of the gate 10 with respect to each other. That is, the transverse beams can be arranged in a plurality of such as the transverse frames of the ladder and can be joined between the end beams 30. This transverse beam can enhance the durability of the water gate 10 by supporting the two end beams 30 and withstanding the water pressure the skin plate 40 is subjected to.

1 to 3, the water gate 10 may further include a lining portion 34. [ The lining portion (34) And may be formed in a plate shape having a thickness.

The lining portion 34 is formed of a strip-shaped metal thin plate having a constant width and is formed on a part of the outer surface of the skin plate 40 in the direction in which the end of the watertight portion 20 extending from the round portion 21 is disposed And can be protruded from the front surface of the skin plate 40 by the thickness of the lining portion 34. [

The lining portion 34 may be made of a metal, particularly a metal resistant to corrosion such as stainless steel. The lining portion 34 is made of stainless steel so that it is possible to prevent the lining portion 34 and the free end portion 21a of the rounding portion 21 from being corroded or rubbed against the rubbed portion.

The lining part 34 is joined to the head 31 of the longitudinal beam 30 so as to surround the head 31 of the longitudinal beam 30 where the free end 21a of the watertight part 20 is located, Shaped metal thin plate having a constant width so as to protect all the range of movement of the free end 21a by the elastic deformation of the free end 21a.

On the other hand, as shown in FIG. 3, the end beam 30 may include a stopper 35.

The stopper 35 may have a plate shape that is narrower than the lining portion 34 and may be bonded to the outer surface of the lining portion 34 in the same direction as the transverse direction of the stream and may protrude from the front surface of the lining portion 34.

The stopper 35 is formed by retreating from the outer end of the lining part 34 to the inside of the water gate 10 by a predetermined distance from the outside end of the lining part 34. In the state where the round part 21 is not elastically deformed, The free end portion 21a of the movable member 21 is spaced apart from the free end 21a by a predetermined distance.

The free end 21a of the stopper 35 and the rounding portion 21 can be located on the same line of the lining portion 34. [ The free end 21a of the rounded portion 21 is selectively moved along the lining portion 34 by the water pressure so as to be able to rub against the stopper 34. [

At this time, the stopper 34 serves as a latching jaw for limiting the section to be moved when the free end 21a of the rounding portion 21 is moved by an external force.

On the other hand, the stopper 35 may be made of metal, especially stainless steel or a metal resistant to corrosion. The free end 21a of the stopper 35 and the rounded portion 21 can be prevented from being corroded or rubbed because the stopper 35 is made of a metal resistant to corrosion.

The head 31 of the end beam 30, the lining part 34 and the stopper 35 can be fastened together by the first fastening part 50 and fixed integrally. At this time, a first through hole (not shown) may be formed in the head 31 of the terminal beam 30, the lining portion 34, and the stopper 35 so as to penetrate the first fastening portions 50 at positions corresponding to each other. have.

The rear end 22 of the watertight portion 20 extending from the rounding portion 21 and coupled to the abdomen portion 32 of the end beam 30 can be fastened to the second fastening portion 60. [ At this time, a second through hole (not shown) may be formed in the rear portion 22 and the abdomen portion 32 of the terminal beam 30 so as to allow the second coupling portion 60 to pass therethrough.

When the water gate 10 is installed in the transverse direction of the river according to the embodiment of the present invention, the watertight portions 20 joined to the baffle plate 32 of the longitudinal beam 30 come into contact with each other, And other structures are brought into contact with each other.

Accordingly, an external force is transmitted to the watertight portion 20 due to the contact with the watertight portion 20 or another structure of the other watertight door 10, and the watertight portion 20 is elastically deformed by an external force. The free end portion 21a of the rounding portion 21 moves in the direction of the water gate 10 and comes into contact with the front end of the stopper 35. [ At this time, the water pressure acts in a direction perpendicular to the free end portion 21a, so that the free end portion 21a can be brought into close contact with the lining portion 34. [

Therefore, the space between the neighboring water gates 10 can be completely sealed and watertight.

As shown in Figs. 1 to 3, the water gate 10 has the watertight portion 20 described above on the baffle plate 32 of one of the two end wings 30, The ribs 70 may be joined to the corner space formed by the head 31 of the cover 30 and the bumper plate 32. That is, in the case where the watertight portion 20 is formed in one of the mutually contacting end beams 30 of the two water gates 10, the rib 70 may be joined to the other end beam 30.

The ribs 70 serve to firmly support the metal plate 70, which will be described later, and can absorb an impact transmitted to the metal plate 71. At this time, a plurality of ribs 70 may be joined in parallel along the height direction of the longitudinal beam 30. The ribs 70 may be formed of a metal plate having a predetermined area.

On the other hand, the ribs 70 and the skin plate 40 can be joined by arranging the metal plates 71 having the both ends 71a bent in the same direction as the flow direction. At this time, the ends of the ribs 70 and the skin plate 40 may be formed so as to be located on the same line in the outward direction of the bumper plate 32. So that the metal plate 71 can be arranged parallel to the bend plate 32.

The metal plate 71 may be joined to the rib 70 and the skin plate 40 by welding. The metal plate 71 can be brought into close contact with the rounded portion 21 of the other mating side gate 10.

The metal plate 71 is made of a thin strip of metal having a constant width and can extend along the height direction of the water gate 10. [ Therefore, corrosion or rubbing of the portion of the metal plate 71 which is in contact with the rounded portion 21 can be prevented, as the metal plate 71 is made of stainless steel or a metal resistant to corrosion.

The frictional force which is applied when opening and closing the water gate 10 of the present invention in which the metal plate 71 and the watertight portion 20 made of stainless steel are formed has a frictional force when opening and closing the watertight door formed of a conventional rubber material .

When the metal plate 71 and the watertight portion 20 provided respectively in the two watertight doors 10 are rubbed by an external force, the watertight portion 20 is elastically deformed, So that the watertightness between the two water gates 10 is tightened.

Also, since the metal plate 71 and the watertight portion 20 are made of a metal having low corrosivity, it is possible to prevent rusting or corrosion of the metal plate 71 and the watertight portion 20 even if they are rubbed.

Also, the water gate 10 of the present invention can be opened and closed with less force than conventional water gate by applying the watertight portion 20 made of a thin metal plate, and the capacity of the water gate opening and closing apparatus can be remarkably reduced.

In the present invention, one or more water gates are installed between structures installed in a river, which are illustrated in the drawings.

However, when the water gate 10 is installed in a narrow river, that is, when a single water gate 10 is provided between the structures, the watertight portion 20 of the end beam 30, which is joined to the abdomen plate 32, Depending on the trajectory, the lining can also be applied to the structure. Lining the structure is to coat the surface of the structure to prevent the structure from cracking and peeling off by the gate.

Therefore, the watertight portion 20 can be joined to the lapping structure 32 and the bending plate 32 of the adjacent longitudinal beam 30. Accordingly, the watertight portion 20 is brought into contact with the lined structure, and the space between the structure and the watertight door 10 can be sealed.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
