[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water gate structure for water intake.

[0002]

2. Description of the Related Art Conventionally, as a water gate used for temporarily opening and closing a river, a steel gate is provided so that it can be turned upside down so that the water of the river can be used for a certain purpose. If you want to store water, stand up the gate and block the drainage, and if the water volume increases or you do not need to block it, turn the gate over and restore the normal river flow. There is.

The gate is made of steel, and a rib for reinforcement is erected on the back side, and steel sliding plates are stretched on both side walls so as to be watertight with the seal rubber on the side edge of the gate. I have set up.

[0004]

However, the conventional sluice gate has the following drawbacks.

That is, since the gate material is a steel plate, the gate surface side facing the weir side, that is, the upstream side of the river is prone to corrosion due to long-term use, and rust etc. is generated on the gate surface side. There is a possibility that unevenness will be formed on the surface to block the flow of water, or dust mixed in water will be caught in the uneven part and interfere with the flow of water further. , It was difficult to blend in with the natural appearance of the surroundings, making it unsightly.

Further, in order to retard the corrosion of the steel sheet as much as possible, the surface of the steel sheet is coated with corrosion-preventive paint, so that the color of the paint and the texture of the steel sheet do not match the natural appearance of the surroundings, and the landscape of the natural environment. Was to destroy.

[0007]

According to the present invention, left and right sliding plates made of stone plates such as granite are attached to both side surfaces of a river, and a gate plate approximately equal to the width of the river is tipped between the left and right sliding plates. The gate plate is erected freely and is composed of a substantially square steel plate and a drainer protruding from the upper edge of the steel plate, and stone plates are attached to the steel plate and the surface layer facing the upstream side of the river. It is intended to provide a sluice structure for water removal.

EFFECTS OF THE INVENTION According to the present invention, a stone plate is attached to the surface layer of a gate composed of a substantially square steel plate and a drainer, and stone plates such as granite are attached to both side walls of the river on both sides of the gate. Since it is smooth, the surface in contact with the water flow will not be corroded forever, and the water flow will be smooth, and since it is a stone plate, it is not necessary to apply paint for corrosion prevention etc. , It is possible to obtain a natural texture and a natural surface pattern, it is easy to assimilate to the surrounding landscape, the appearance does not cause discomfort to the viewer, and artificial functional features are applied without destroying the natural landscape. In addition, since the gate has a stone plate attached, weight is added to the gate, and even if there is a change in the flow of water, the function of the dam is not changed and it is functionally stable. There is an effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described. FIG. 1 is a front view showing a water gate structure of the present invention, and FIG. 3 is a sectional view of FIG. , B is
It shows both side walls of river A and is constructed with stone walls or concrete blocks.

A sluice gate C is provided in the middle of the river A. The sluice gate C is a gate plate 1 made of a steel plate which is provided so as to be able to fall and stand, and a wire winding device 3 in which the gate plate 1 is connected by a wire 2. And left and right sliding plates 4 located on both sides of the gate plate 1.

The river bottom 5 on the upper side of the sluice C is formed one step higher than the river bottom 6 on the lower side, and is provided with a step portion 7. The step portion 7 is provided with a cover plate 8 made of stainless steel and having a substantially inverted L-shaped cross section. The left and right brackets 10 are covered and are provided on the bottom surface of the riverbed 6 on the lower side via a stainless bottom plate 9, and the bracket 10 is provided on the bottom surface of the lower end of the gate plate 1 via a pivot 11. A gate bracket 14 is pivotally supported.

The gate plate 1 made of a steel plate is provided with a required rib frame 13 on the back surface of the flat steel plate 12 to reinforce the flat steel plate 12, and the lower end of the flat steel plate 12 and the riverbed 5 on the upper side. A watertight rubber plate 15 is provided between them to prevent water from leaking between the gate plate 1 and the river bottom 5 on the upper side. 15-1 is a watertight rubber plate 15
Reference numeral 15-2 denotes a fixing plate for fixing one edge of the same to the cover plate 8, and 15-2 denotes a fixing plate for fixing the other edge to the gate plate 1.

A stone plate D having a constant thickness is attached to the surface layer on the upper side of the gate plate 1.

As the stone plate D, granite is used, and in some cases, square stone plates D are laid adjacent to each other, and a stainless steel holding flange 16 is interposed between them.

A seal rubber plate 17 is continuously provided on both side edges of the gate plate 1, and the seal rubber plate 17 is brought into contact with the left and right sliding plates 4 attached to both side walls B of the river A and the game plate. 1
It functions as a seal on both edges.

The left and right sliding plates 4 are made of a stone plate D also made of granite.

Further, a drainer 18 having a V-shaped cross section is projected from the upper edge of the gate plate 1, and a stone plate D is also attached to the upper surface layer surface of the drainer 18.

When the gate plate 1 is turned over about the pivot 11 to make it horizontal, the stone plate D on the surface of the gate plate 1 is pivoted so as to be at substantially the same level as the upper riverbed 6.
Positions such as 11 and bracket 10 are provided.

When the gate plate 1 falls and stands up, except when it is carried out by the wire winding device 3 via the wire 2, it is carried out by a hydraulic cylinder provided between the gate plate 1 and the riverbed 6 on the lower side. Etc.

The wire winding device 3 is arranged on the ground surface which is the upper end of both side walls B of the river A, and winds the wire 2 connected to the upper corner of the gate plate 1 by an electric motor provided inside. The take-up operation is performed to perform the fall and erect operation of the gate plate 1.

The embodiment of the present invention is configured as described above, and when blocking the flow of water from the upper side to the lower side, the wire winding device 3 is operated to operate the gate plate 1. To stand vertically.

The gate plate 1 is provided with a stone plate D on the surface layer on the right side, and the water that blocks the flow of water by blocking the river A with the stone plate D surface is on the left and right sides of the gate plate 1. The seal rubber plate 17 and the watertight rubber plate 15 completely seal and do not flow out from the lower end or both side ends of the gate plate 1.

If the water level on the right side rises, the water will flow over the upper edge of the gate plate 1, and at this time, the draining body 18 will reduce running noise as much as possible.

The amount of blocking on the upper side is adjusted by the inclination angle of the gate plate 1, which adjusts the amount of wire drawn by the operation of the wire winding device 3.

The overflowing water overflows the upper edge of the gate plate 1 and flows out to the lower side.

In the sluice gate structure for water removal according to the present invention constructed and operated as described above, since the stone plate D is attached to the gate plate 1, the gate plate 1 is slipped due to the sliding state of the surface layer of the stone plate D. Smooths the flow of water in case of tumbling, so that the dirt and mixture mixed in water is less likely to adhere to the stone plate D surface, and the amount of adhered material is smaller than that of the conventional steel plate having an uneven surface. Only the flow of water becomes smooth, and it is possible to reduce the foul-smelling component formed by deposits as much as possible.
This reason can be applied also to the case of the stone plate D provided on the draining body 18 and the left and right sliding plates 4 on both sides, and by using the stone plate D, adhered matters such as water residue and dirt are reduced, and The odor in the area can be removed as much as possible, and moreover, the landscape of the sluice has a natural texture and the colors and patterns are natural, so it matches the surrounding outside scenery and becomes easy to blend in. , And has the effect of not being assimilated together and destroying the natural appearance.

In particular, the place where the stone plate D is attached is a surface which is always in contact with water, and by providing a natural stone plate at this portion, there is no possibility of corrosion, and conventionally, the steel plate is corroded at this place. By doing so, it is possible to eliminate the drawback that odor and the like are deposited and accumulated to give off a bad odor.
