Description

HYDRAULIC CONDUCTION FLOODGATE WITH IMPURITIES INTERRUPTER < RTI ID = 0.0 >

The present invention relates to a conductive water gate having an improved foreign matter blocking portion, and more particularly, to a foreign matter blocking portion that is rotated in conjunction with opening and closing of a water door on the downstream side of an irrigation waterway provided with a water gate, The present invention relates to a conduit gate which is capable of blocking foreign matter more efficiently by being folded and folded.

Conduction gates are used to flood water in reservoirs, floods of irrigation channels such as rivers and rivers, or floods due to heavy rainfall, and gates used as movable beams for the purpose of securing various kinds of water.

These conduction gates are mainly called hydraulic conduits because they can be opened and closed by hydraulically operated cylinders.

The hydraulically operated conduit described above can be raised or lowered according to the expansion and contraction of the hydraulic cylinder installed at the bottom of the irrigation channel. It is possible to maintain the hydrone upright for a long period of time for freshwater purposes, There is a problem in that the foreign material is accumulated around the bottom of the irrigation channel to be positioned, and the water gate is not opened and closed smoothly.

1 is a conceptual diagram showing a known structure of a conductive watertight door for removing foreign matter.

The prior art according to FIG. 1 is a conduit gate for easy removal of foreign matter, which is disclosed in Korean Patent No. 1040322, in order to prevent the deposit from accumulating around the front of the gate.

More specifically, the prior art described above is based on the fact that, as can be seen from FIG. 1, the hydraulic cylinder b is mounted on the upper side of the housing of the hydraulic cylinder b or on the upper side of the hydraulic gate a, The upper end of the foreign material removing plate c is hinged to the upper side of the rear surface and the roller d integrally provided at the lower end of the foreign material removing plate c is seated on the downstream side bottom surface, And the upper end of another auxiliary foreign material removing plate (e) is hinged.

According to this structure, the foreign material removing plate (c) is positioned in front of the water gate (a) to block the foreign substance, and the auxiliary foreign material removing plate (e) covers the space below the back side of the water gate (a) It is possible to prevent water or foreign matter falling over the upper end of the water surface from flowing into the space below the water surface.

However, according to this structure, even if the foreign material removing plate is installed at the bottom of the foreign material removing plate because the radius for moving the foreign material removing plate in the forward and backward direction of the floor is unnecessarily long due to the roller installed on the bottom when opening and closing the water gate, It is more likely that the foreign material removing plate will not move because the roller is not rotated due to the foreign material or the stones on the rugged floor rather than pushing out the accumulated foreign matter. In order to move the roller uniformly on the floor, It is troublesome to perform planarization work.

Further, it has been described that the auxiliary foreign material removing plate slides along the upper side of the foreign material removing plate while scraping foreign substances deposited on the foreign substance removing plate. In order to remove another foreign material deposited on the foreign material removing plate, There is a disadvantage in that the installation cost is higher than the utility of the use, which is not economical.

Particularly, in order to cover the entire area of the foreign substance removing plate and to prevent the water gate from being completely laid due to the auxiliary foreign substance removing plate, the auxiliary foreign substance removing plate must be formed much longer than the one shown in the drawing In this case, the auxiliary foreign matter removal plate inevitably comes into contact with the floor of the irrigation canal in the state where the floodgate is in a lying state, so that unnecessary friction with the floor is caused. In addition, There is a problem that the foreign substance removing plate may not return to the foreign substance removing plate again due to the foreign substance.

Therefore, there is a need to develop a new and advanced conductive water gate capable of efficiently blocking foreign matter with a simpler structure by improving the foreign matter removing plate and the auxiliary foreign matter removing plate.

SUMMARY OF THE INVENTION The present invention has been devised to overcome the problems of the prior art, and it is an object of the present invention to improve the foreign matter removing plate in the above-mentioned prior art to a foldable structure by minimizing the contact area with the bottom of the related waterway It is a principal object of the present invention to provide a conductive water gate having a foreign matter blocking portion that can reduce friction with the floor by eliminating troublesome operation to move along the floor.

Another object of the present invention is to provide a screen that extends to the outside of the foreign matter blocking portion while covering the surface of the foreign matter blocking portion, thereby effectively dropping the foreign matter deposited on the surface of the foreign matter blocking portion when gravity is used.

It is a further object of the present invention to provide a bend at the end of the screen to reduce friction with the bottom of the associated waterway.

It is a further object of the present invention to provide a step on the surface of a screen to more effectively induce falling of grains deposited on the surface of the screen in a gravitational direction.

In order to accomplish the above object, the present invention provides a conduit gate having an improved foreign matter blocking unit, comprising: a water gate installed on one side of an irrigation water channel and vertically or horizontally raised and lowered; A hydraulic cylinder which rotates and lifts the water gate in a state of being rotatably extended via a cylinder hinge at the bottom of the irrigation water channel and a lift hinge at a front side of the water door; A basin connected to the water gate via a base hinge on one side of a front surface of the water inlet, as a plate member, connecting the one side of the front surface of the water can, which is spaced apart from the hydraulic cylinder in the downstream direction, And a foreign matter blocking unit comprising a connector extending through a connector hinge at the bottom of the housing and a connection hinge for pivotally connecting the base and the connector.

The foreign matter blocking unit may further include a screen having a lamination portion that covers a part of the surface of the base and an extension portion that extends outwardly from the base portion in the lamination portion,

In addition, the end portion of the screen is formed as a bent portion bent upwards with respect to the extending direction of the screen.

In addition, the screen may include a plurality of stepped portions that are formed stepwise in a stepped manner while being extended to an end.

According to the conduit gate having the improved foreign matter blocking portion according to the present invention,

1) The foreign matter blocking part located at the front end side of the hydraulic cylinder is folded and rotated in the opening and closing process of the water inlet, so that foreign matter is prevented from flowing into the hydraulic cylinder side and the friction with the bottom of the related waterway can be blocked,

2) It is possible to drop foreign substances deposited on the foreign matter blocking part through the screen which minimizes the friction with the floor during the opening and closing of the water door,

3) When the screen touches the floor, the bending part reduces the problem of being bent or caught by the friction with the floor,

4) It has the effect of solving the problem of foreign matter deposition which can occur when opening / closing the water gate more efficiently by various structures added to the screen.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

Fig. 2 and Fig. 3 are sectional views showing the basic structure of the conductive water door of the present invention and the elevation state thereof.

The water gate (10) of the present invention is mounted via a frame (1) provided on both sides and a bottom of an irrigation channel such as a river or a river. Especially, the water gate (10) stands upright in a vertical structure centered on a hinge As shown in FIG.

In the present invention, the rising of the water gate 10 in a vertical structure is referred to as a rising, and the lying in a horizontal structure is referred to as a falling. 2 and 3, the upper surface of the four sides of the water gate 10 is referred to as a rear surface 12 as a fresh water surface (surface contacting the stored water) when the water gate 10 stands, The surface facing the downstream of the channel is referred to as the front surface (11).

Such a water gate 10 is raised and lowered by the rotation of the water gate hinge 13 by the driving of the hydraulic cylinder 20.

Specifically, the hydraulic cylinder 20 is rotated and contracted by the cylinder hinge 21 mounted on the bottom of the irrigation channel, and the piston (or plunger) is extended and contracted. The end of the piston (or plunger) 22 to the one side of the front face 11 of the water gate 10. [ Since the connection between the hydraulic cylinder 20 and the sluice gate 10 is the same as that of the known sluice gate, a detailed description thereof will be omitted.

The foreign matter blocking portion 100 of the present invention connects the one side of the front surface 11 of the water gate 10 spaced from the hydraulic cylinder 20 in the downstream direction to the bottom of the irrigation water channel, And a connector 120 connected to the base 110. As shown in FIG.

The base 110 is an elongated structure connected to one side of the gate 10 via a base hinge 111. The base 110 is preferably made of a plate or panel and extends to both ends of the irrigation channel in the same manner as the gate 10 . At this time, the base 110 may be divided into a plurality of sections based on the width of the irrigation channel, and in this case, the connectors 120 are also installed in the number corresponding to the number of the bases 110.

The connector 120 connects the bottom of the irrigation channel with the base 110. The connector hinge 121 is connected to the bottom of the irrigation channel and the other end is connected to the base 110 via the connection hinge 130. [ ). The connector 120 may have a panel shape as in the case of the base 110. However, the connector 120 may be formed in the form of a rod or rod when the screen 200 is mounted on the base 110, Do.

At this time, the base 110 and the connector 120 may extend to the same length. However, in order to minimize the portion of the connector 120 contacting the bottom of the irrigation channel during the folding, It is preferable that the connector 120 is formed longer than the connector 120.

The operation of the conduit of the present invention having such a structure will now be described with reference to FIGS.

2, the base 110 and the connector 120 are in a folded state when the gate 10 is initially laid down. At this time, both the base 110 and the connector 120 are extended toward the downstream direction . In other words, the folded state of the base 110 and the connector 120 takes a folding and pivoting structure that protrudes convexly toward the downstream direction, which causes the base 110 and the connector 120 in the connecting hinge 130 to move in the downstream direction (For example, by providing a stopper at a connection end of the connection hinge or the base and the connector to induce rotation in a specific direction).

The reason why the base 110 and the connector 120 are folded so as to protrude downstream in the downstream direction is to prevent foreign matter from accumulating in the front space of the foreign matter blocking portion 100 in the irrigation water channel, The foreign matter remaining in the vicinity of the first space 2 is pushed downward in the ascending and descending direction of the water gate 10 and the space between the hydraulic cylinder 20 and the foreign matter blocking portion 100, So as to prevent foreign matter from flowing into a part of the second space (3).

2, a portion of the base 110 connected to the connector 120 (i.e., a peripheral side surface of the connection end) is inserted into the base 110 in a predetermined length along the longitudinal direction of the base 110. As a result, And a connecting hinge 130 may be movably installed along the space in the slit 112. [

2, the angle formed between the base 110 and the bottom of the irrigation canal becomes smaller, and the connecting hinge 130 can be positioned closer to the bottom of the irrigation canal, The portion 100 can be kept in a folded state.

At this time, even if a part of the foreign matter is deposited in the first space 2, the foreign matter blocking part 100 can be folded. However, since the base 110 and the connector 120 are ' The radius of the lower portion of the foreign matter blocking portion contacting the bottom of the foreign matter blocking structure is shorter than that of the known negative (-) structure, so that the foreign matter remaining in the first space 2 is less adversely affected.

In addition, since the base 110 is not horizontally but is inclined downwardly in a state where the foreign matter blocking portion 100 is folded, it is possible to provide a property of blocking foreign matter from accumulating on the surface of the base 110 .

Thereafter, when the hydraulic cylinder 20 operates while extending the piston in the hydraulic cylinder, the water gate 10 rises in the order shown in Figs. 2 and 3 and the foreign matter blocking portion 100 is unfolded. In this way, water and foreign substances are rapidly introduced into the first and second spaces 2 and 3 due to a difference in water pressure during the ascending of the water gate 10. At this time, the second space 3 is blocked by the foreign matter blocking portion 100, The end portion of the base 110 on which the connection hinge 130 is installed is positioned in the first space 2 in the process of descending the water gate 10. In this case, It is possible to prevent foreign matter from accumulating on a part of the first space 2 by folding the connector 120. [

In addition, since the foreign matter blocking portion 100 is maintained in the unfolded state in front of the water gate 10 when the water gate 10 stands up, foreign matter falling over the water gate 10 also flows into the second space 3 Of course it is to block things.

FIG. 4 is a cross-sectional view illustrating the lifting and lowering state of a watercourse in a screen state in the foreign matter blocking portion of the present invention. FIG.

4, the screen 200 may be further provided on one surface of the base 110, specifically, on the surface of the base 110 facing the water surface.

The screen 200 of the present invention is formed of a plate member and has a structure that covers at least a part of the surface of the base 110 but extends to the outside of the base 110 through an end of the base 110 connected to the connector 120. To summarize this again, the screen 200 means that it is composed of a lamination part 201 covering the base 110 and an extension part 202 extending outward from the base 110 in the lamination part 201 to be,

At this time, the screen 200 may cover the entire surface of the base 110, or may cover a part of the surface of the connection hinge 130 side and may be embedded in the surface of the base 110 on the side of the connection hinge 130 Or may be stacked on the depression.

The laminated portion 201 may take any one of the structures covering the entire surface or a part of the surface of the base 110, but it is preferable that the extension portion 202 having a line that matches the portion covered by the base 110 as much as possible, . In addition, the screen 200 is made of a material and a thickness that are not easily bent or warped due to an external force and can be detached from the base 110 so that the base 110 can be replaced at regular intervals. (For example, a bending / concavo-convex coupling structure or the like) interlocked with the surface structure of the screen 200 can be provided.

Such a screen 200 may be constructed such that the screen 200 flows on the surface of the base 110 or a foreign matter passing over the water gate accumulates foreign matter in the first space 2 during the lifting of the water gate 10 or the folding of the foreign matter blocking portion 100 It provides the function to prevent.

That is, a portion extending from the screen 200 through the base 110 to the outside, that is, the extension portion 202 blocks foreign matter from accumulating in the first space 2, that is, the foreign matter blocking portion 100 is unfolded The screen 200 covers a part of the foreign substance blocking portion 100, that is, the base 110 while the foreign substance blocking portion 100 is inclined upright, The extension portion 202 of the screen 200 is brought into contact with the bottom of the irrigation canal so that the bottom of the irrigation canal can be prevented from falling down. It is possible to more completely block the problem of foreign matter remaining in the first space 2 because the foreign matter is pushed in the downstream direction by scratching.

Further, the bent portion 210 may be further provided at the end of the screen 200, that is, at the end of the extending portion 202, which is bent upward with respect to the extending direction of the screen 200.

The bent portion 210 not only provides a function of delaying the falling speed of the foreign material when the water drops 10 fall along the screen 200 while the foreign material blocking portion 100 is folded, It is possible to scrape off the foreign matter in the downstream direction of the irrigation waterway while raising the foreign matter placed on the floor to move the foreign matter away from the second space 3 in the direction away from the second space 3 more efficiently.

In addition, the bent portion 210 is made of an elastic material such as rubber or silicone and has a bent groove 211 extending in the width direction of the screen 200 from the inner surface (the surface facing the bottom) of the screen 200 It is possible to form a plurality of screens 200 at regular intervals along the longitudinal direction of the screen 200.

That is, the problem that the bending part 210 contacts the bottom of the irrigation water channel when the water gate 10 is laid down can be broken or bended due to the impact generated when the water is contacted. The bending part 210 is made of an elastic material It is possible to prevent a problem such as breakage caused by the elasticity of the bending portion 210 and to bend the bending portion 210 according to the strength of the strength of the bending portion 210 against the bottom of the irrigation channel through the plurality of bending grooves 211, It is possible to control it.

5 is a conceptual diagram showing a first modified embodiment in which the screen of the present invention is rotated.

5, the connection part between the base 110 and the connector 120, that is, the periphery of the connection hinge 130, that is, the connection part between the laminate part 201 and the extension part 201, The screen rotation unit 220 may be additionally formed at a boundary portion of the screen rotation unit 202 to rotate the extension unit 202 with respect to the screen rotation unit 220.

As a first embodiment of the present invention, first, a screen 200 is provided around the connection portion between the base 110 and the connector 120 along the width direction of the screen 200, A drive shaft mounted in an extended state, and a motor for rotating the drive shaft, so that the extension portion 202 can be rotated by driving the motor in the forward and reverse directions.

In addition, as the second embodiment, the hydraulic cylinder is additionally mounted on one side of the connector 120, and the screen 200 can be rotated by the operation of the hydraulic cylinder. Of these, the first embodiment that saves space while ensuring the free rotation direction of the extension 202 is more preferable, but various known mechanical rotation means can be applied instead of these two embodiments.

The screen turning unit 220 is designed to pivot the extending portion 202 upward or downward according to circumstances. For example, when a pressure higher than the reference pressure is applied to the extension 202, the extension 202 can be pivoted downward to prevent the extension 202 from being bent, and the extension 202 can be moved to the bottom of the irrigation canal So that the extension portion 202 can be rotated upward when the foreign matter is scratched.

Furthermore, the pressure sensor 202a is additionally mounted on the surface of the extension portion 202 to determine whether the screen rotation unit 220 is driven according to the pressure measured by the pressure sensor 202a, You can control it.

5, a spike 212 is additionally formed in the periphery of the bent portion 210. [

Specifically, the spike 212 refers to a structure formed by projecting a plurality of spikes 210 at regular intervals along the width direction of the extended portion (bent portion) on the inner side (bottom surface) of the inner and outer surfaces of the bent portion 210. The spike 212 is made of a nonmetallic material having a small load, so that the bending portion 210 is prevented from being bent downward by the load of the spike.

The spike 212 is tapered as it extends to the end, so that the spike 212 is pierced between stones or layings placed on the floor of the irrigation waterway when the water gate 10 is in a lying state, And functions to prevent unnecessary flow of the screen 200 including the extension portion 202 according to the flow of water.

Furthermore, at least one of these spikes 212 may be of a length adjustable construction. In other words, the spike 212 can be mounted at the end of the length adjuster, which is not shown in the figure but has the same structure as a known car folding antenna, so that it can dig into the bottom of the irrigation canal and tightly engage with the bottom of the irrigation canal Of the total. In this case, the length adjuster is not necessarily limited to the antenna structure, and the hydraulic cylinder described above may be manufactured in a small size.

Fig. 6 is a conceptual view showing a second modified embodiment in which the screen of the present invention has a stepped structure.

As shown in FIG. 6, the screen 200 includes a plurality of stepped portions 230 that are stepwise processed as the process proceeds to the end.

The height of the step 200 can be adjusted according to the thickness of the screen 200. When the screen 200 is placed in the irrigation channel for a long time in a state in which the screen 200 is not horizontal, It is possible to prevent accumulation of foreign matter on the surface (outer surface) as much as possible and assist the foreign matter to fall along the step 230 in the gravity direction. In order to prevent the gradually increasing thickness of the lean so as to extend downward by the stepped structure of the step 230, the extended surface 230a of the stepped portion is not parallel to the lower surface 200a of the screen but slightly downward It is preferable to extend in an inclined manner.

In addition, it is possible to form protrusions 240 protruding at a constant height on the surface of the entry-side surface of each step 230.

The protrusion 240 prevents foreign matter from accumulating on the surface of each step 230. In other words, when the foreign material moves from one of the step 230 to the downstream side step 230, And the foreign matter that comes into contact with the protruding portion 240 is separated from the surface of the step 230 without being adhered to the surface of the protruding portion 230, do.

Specifically, the protruding portion 240 includes a first rounding portion 241 extending in a rounded shape toward the downstream direction of the irrigation water channel with a first curvature (an inverse number of the radius of curvature) at the entry surface of each step 230, And a second rounding portion 242 that is extended in a convex shape as a second curved line so as to touch the surface of the step portion 230 by changing the extending direction at the end portion t of the first rounding portion 241 At this time, the first curve is smaller than the second curve.

6, the projecting portion 240 is directed not only in a downward direction but also in the direction of the surface of the step portion 230 so as not to be too sharp. As a result, foreign matter does not fall compared with the pointed structure, 240 as well as a function of falling apart from the stepped portion 230 as described above.

As described above, the configuration and operation of the conductive watertight door having the improved foreign matter blocking unit according to the present invention are described in the above description and drawings. However, the present invention is not limited to the above description and drawings. And it is to be understood that various changes and modifications may be made without departing from the spirit of the invention.
