Description

The present invention relates to an undulation gate used for the purpose of raising or discharging water flowing in a water channel by standing up or lying freely with a rotating shaft provided at the bottom of the water channel.

Conventionally, as a undulation gate, a wire rope or chain is attached to the head of a steel door body with a sufficiently strong cross or vertical girder against a steel plate (water stop plate) that receives water pressure, and this is installed on land. A type that winds up or rewinds with a hoisting machine and raises or falls, or a similar steel door body is pushed up by a hydraulic cylinder installed at the bottom of the downstream waterway, and the hydraulic cylinder is reversed. Various types have been developed and used, such as shrinking and lying down.

In recent years, steel is made by inflating the air bag by injecting air into the air bag installed at the base downstream of the steel door body anchored to the bottom of the channel with a flexible and strong band made of rubberized fabric. A type in which the air bag is shrunk and the steel door body is laid down by raising and lowering the door body and exhausting air having pressure from the air bag has been developed and used.

By the way, the undulation gate has a structure in which the water flowing through the water channel is once blocked, but flows over the tip of the steel door body and flows further downstream. The gate is excellent in safety, safety and operability.

Recently, however, there has been an increase in public demand for public facilities that do not disturb the landscape of the gate section and the neighborhood.
1) When the undulation gate is not overflowing, it is hard to be familiar with the appearance of the artifact.
2) It feels rough when it overflows a lot, and the sound of falling water is loud and annoying.
3) Divide the living environment of fish and aquatic organisms and destroy the environment.
Many criticisms have been heard.

Therefore, in order to realize an area-friendly undulation gate that responds to the voices of the surrounding citizens seeking such a “friendly undulation gate”, the applicant has conventionally raised or laid one steel door body. According to Japanese Patent Application No. 2001-256610 (Japanese Patent Application Laid-Open No. 2003-64651, Patent Document), a proposal for improving the undulation gate that has been dammed up or discharged into a undulation gate that uses two steel door bodies. 1).

That is, the upper part of the steel door body having the rotating shaft at an appropriately low position on the downstream side is compared with the main hoisting gate installed by tilting the upper part of the steel door body having the rotating shaft upstream to the downstream side. Tilt to the upstream side, and insert it under the steel door body of the main undulation gate so that it can be undulated freely to make the sub undulation gate.

In addition, after the operation roller at the tip of the steel door body of the subsidiary undulation gate is combined to support the steel door body of the main undulation gate, the steel door body of the subsidiary undulation gate is The steel door body of the main undulation gate is operated by performing the undulation operation.

If constructed in this way, the steel door body of the main undulation gate is responsible for the function of weiring and discharging the original running water of the undulation gate, and the steel door body of the sub undulation gate was generated at the undulation gate Disperses the momentum of the water flowing down the head of the water surface to relieve the harshness and noise of the landscape, and at the same time functions to relieve the sense of incongruity by making the landscape of the undulating gate from the downstream side resemble the rapid stream of a natural river At the same time, it is also responsible for the functions of the main undulation gate operating device.

As described above, the present invention is a new technology capable of meeting new social demands by additionally installing the reverse undulation gates at the positions where they interfere with each other on the downstream side of the steel door body of the conventional undulation gate. It is possible to provide undulating gates.
Japanese Patent Application No. 2001-256610 (Japanese Patent Laid-Open No. 2003-64651)

However, in the preceding undulation gate, water or the like overflowing from the upper end of the door body of the undulation gate hits the upper surface of the door body of the undulation gate, and the door body of the sub undulation gate is There was a problem that it was easily damaged and caused anxiety in terms of durability.

Therefore, the undulation gate of the present invention allows a secondary flow guide plate to freely rotate on the upper part of the main undulation gate door body, so that the undulation gate overflows the main undulation gate door body not only in the standing state but also in the overturned state. The water flowing on the upper surface of the door body of the sub undulation gate is made to flow gently with the auxiliary flow guide plate so as to reduce the intensity of the overflowing water.

According to the undulation gate of the present invention, the auxiliary flow guide plate is rotatably attached to the upper part of the main undulation gate door body, thereby flowing over the main undulation gate door body and flowing over the upper undulation gate door body. I was able to reduce the intensity of water.

Of course, according to the hoisting gate of the present invention, it is a part of a device for hoisting the hoisting door body on the downstream side of one hoisting door body that dams up the water upstream, and at the same time the downstream hoisting gate. Various effects could be obtained by installing another undulating door body having a function of an inclined surface for gently flowing water. That is,
a) The landscape of the relief gate, especially the landscape from the downstream, became very calm. In particular, it has become possible to consider placing stones on the upper surface of the undulation gate.
b) The noise of the undulation gate could be reduced. Since the water that flows over the undulation gate does not fall at a height above the weir, it flows down the inclined surface, so the amount of noise generated becomes very small.
c) Anxiety about lodging problems caused by driftwood was resolved.
d) The undulation gate can also function as a fishway. This can be achieved by grading the inclination angle of the sub-undulation gate when standing or processing the surface.
As described above, the undulating gate according to the present invention is a undulating gate excellent in harmony with the environment, and becomes valuable as a river structure in a new era.

1 and 2 show the prior art of the undulating gate of the present invention, FIG. 1 is a sectional view of the undulating gate, FIG. 2 is a sectional view of the undulating gate, FIG. 3 and FIG. 4 shows another prior art of the undulating gate of the present invention, FIG. 3 is a sectional view of the undulating gate, FIG. 4 is a sectional view of the undulating gate, FIG. 5 and FIG. FIG. 5 is a sectional view of an undulating gate in an upright state, and FIG. 6 is a sectional view of the undulating gate in a collapsed state.

In the prior art shown in FIG. 1 and FIG. 2, the bearing 3 of the anchor hardware 2 at the bottom 1 of the water channel having a rectangular cross section and the bearing 5 at the lower end of the steel door body 4 are freely assembled by the shaft 6 and The other side of the rubber plate 9 is attached to the lower surface of the door body 4 by the bolt 10 and the holding plate 11 and can be raised and lowered by being inclined to the downstream side. Thus, water leakage between the door body 4 and the anchor hardware 2 is prevented to form a main undulation gate.

The door body 4 includes a water stop plate 12 that directly receives water pressure, a cross beam 13, a vertical beam 14, and a flow guide plate 15 that protrudes downstream from the head. At this time, the opposite side of the water stop plate 12 of the stringer 14 is a rolling surface 17 of the operation roller 16 that controls the standing or falling of the door body 4, and a roller stopper 18 protrudes downstream from the upper surface. It also plays the role of supporting the flow guide plate 15.

The bearing 20 of the support base 19 installed on the bottom of the water channel with a suitable amount lower downstream of the main undulation gate and the bearing 22 at the lower end of the door body 21 of the sub undulation gate are assembled freely by the shaft 23 and can be undulated. The rolling surface 17 of the vertical beam 14 of the main undulation gate door 4 is supported by an operation roller 16 which is inserted below the door 4 of the main undulation gate and is freely attached to the tip. .

Further, a lower flow guide plate 24 is provided on the upper surface of the lower end of the door body 21 of the sub undulation gate with a plate having strength and elasticity, and the flow guide plate 15 and the door of the sub undulation gate are provided from the upper part of the door body 4 of the main undulation gate. The water stop plate 25 of the body 21 and the water that has overflowed sequentially are discharged downstream from the support base 19.

On the other hand, on the upper surface of the upper end of the door body 21, the water stop plate 25 is bent so that the overflowing water does not spill into the gap between the door body 4 and the door body 21 when moving from the flow guide plate 15 to the door body 21. A raising portion 26 is provided. At this time, the axis 6 of the main undulation gate and the axis 23 of the sub undulation gate are parallel, the axis 23 is lowered by an appropriate amount, and the dimensions of the door body 4, the door body 21, and the operation roller 16 are selected correctly. Thus, when the sub undulation gate is standing or lying down, the operation roller 16 always supports the rolling surface 17 of the vertical beam 14 of the door body 4 of the main undulation gate tilted downstream so as to lean on this. Therefore, the main undulation gate will also stand up or surrender.

Now, in the main undulation gate and the sub undulation gate installed in this way, there are three sides that are reduced to a flat rectangle when the air is discharged on the bottom of the channel near the shaft 23 of the door body 21 of the sub undulation gate. The open side of the air bag 28 made of rubberized cloth, which is closed and opened on one side, is pressed against the anchor bolt 29 and the press plate 30 to fix the opened side in a sealed state. Then, the air pipe 32 connected to the base 31 at the lower part of the air bag 28 is led to the land by burying it in the concrete of the water channel, etc., and the exhaust gas on-off valve 33, the exhaust flow rate adjusting valve 34, the exhaust air 1 and 2 are connected to the discharge unit 35, the air supply on-off valve 36, the air supply flow rate adjustment valve 37, and the air compressor 38.

Then, as a result of press-fitting air into the air bag 28 from the air compressor 38 via the air supply flow rate adjustment valve 37, the air supply on / off valve 36, the air pipe 32, and the base 31, the air bag 28 is sub-raised. A sectional view of the state in which the steel plate 27 on the lower surface of the door body 21 of the gate is pushed up to raise the door body 21, and as a result, the operation roller 16 pushes up the rolling surface 17 of the door body 4 and the door body 4 stands up. 1.

At this time, the other end of the belt 41 made of rubberized cloth having sufficient strength with one end fixed by the bolt 39 and the holding plate 40 on the upper lower surface of the door body 21 is placed on the water channel bottom upstream of the air bag 28 contacting. Since the anchor bolt 42 and the pressing plate 43 are fixed, the door body 21 is stopped by the tension acting on the band 41. That is, the operation roller 16 is not in contact with the roller stopper 18 at the upper end of the stringer 14 of the door body 4. The roller stopper 18 is provided as a safety measure when the belt 41 is damaged.

In FIG. 1, the pressure of the water dammed up upstream by the door body 4 and the dead weight of the door body 4 are supported by the operation roller 16, although the door body 4 tries to fall down clockwise by the shaft 6. This operation roller 16 is rotatably attached to the tip of the door body 21, and an angle at which a line connecting the rolling surface 17 of the stringer 14, the center of the operation roller 16 and the center of the shaft 23 of the door body 21 intersects.閘 is set larger than 90-. Accordingly, the force applied to the operation roller 16 by the door body 4 acts to cause the door body 21 to fall down counterclockwise by the shaft 23. However, since the air bag 28 is inflated by the air having pressure between the water channel bottom and the steel plate 27 of the door body 21 and supports the door body 21, the entire body stands up stably.

On the other hand, the air compressor 38 is stopped, the air supply open / close valve 36 is closed, the exhaust open / close valve 33 is opened, and the pressure inside the air bag 28 is controlled from the exhaust discharge portion 35 while being controlled by the exhaust flow regulating valve 34. As a result of releasing the air having air into the atmosphere, the air bag 28 is flattened and the door body 21 of the subsidiary undulation gate falls down. As a result, the door body 4 that has lost support by the operation roller 16 also falls down. The figure is FIG. Since the operation roller 16 is supported by the base 44, the door body 21 is supported by the operation roller 16 and the shaft 23, and the door body 4 is supported by the operation roller 16 and the shaft 6. Since the surface of the water stop plate of the door body 21 has an appropriate inclination from upstream to downstream, water and earth and sand can flow down without any trouble. At this time, the water leakage generated below the door body 4 and the door body 21 is discharged downstream of the undulation gate by the drain hole 45, and there is no problem.

3 and 4 show another prior art of the undulating gate according to the present invention. FIG. 3 is a sectional view of the undulating gate, and FIG. 4 is a sectional view of the undulating gate. .

3 and 4, the bearing 3 of the anchor hardware 2 at the bottom 1 of the water channel having a rectangular cross section and the bearing 5 at the lower end of the steel door body 4 are freely assembled by the shaft 6 so that the upper part is inclined downstream. The other side of the rubber plate 9 is attached to the lower surface of the door body 4 by the bolt 10 and the holding plate 11, and is attached to the lower surface of the door body 4 by the bolt 7 and the holding plate 8. The main undulation gate is formed by preventing water leakage between the anchor 2 and the anchor hardware 2.

The door body 4 includes a water stop plate 12 that directly receives water pressure, a cross beam 13, a vertical beam 14, and a flow guide plate 15 that protrudes downstream from the head. At this time, the opposite side of the water stop plate 12 of the stringer 14 is a rolling surface 17 of the operation roller 16 that controls the standing or falling of the door body 4, and a roller stopper 18 protrudes downstream from the upper surface. It also plays the role of supporting the flow guide plate 15.

The bearing 20 of the support base 19 installed on the bottom of the water channel with a suitable amount lower downstream of the main undulation gate and the bearing 22 at the lower end of the door body 21 of the sub undulation gate are assembled freely by the shaft 23 and can be undulated. The rolling surface 17 of the vertical beam 14 of the main undulation gate door 4 is supported by an operation roller 16 which is inserted below the door 4 of the main undulation gate and is freely attached to the tip. .

Further, a lower flow guide plate 24 is provided on the upper surface of the lower end of the door body 21 of the sub undulation gate with a plate having strength and elasticity, and the flow guide plate 15 and the door of the sub undulation gate are provided from the upper part of the door body 4 of the main undulation gate. The water stop plate 25 of the body 21 and the water that has overflowed sequentially are discharged downstream from the support base 19.

On the other hand, on the upper surface of the upper end of the door body 21, the water stop plate 25 is bent so that the overflowing water does not spill into the gap between the door body 4 and the door body 21 when moving from the flow guide plate 15 to the door body 21. A raising portion 26 is provided. At this time, the axis 6 of the main undulation gate and the axis 23 of the sub undulation gate are parallel, the axis 23 is lowered by an appropriate amount, and the dimensions of the door body 4, the door body 21, and the operation roller 16 are selected correctly. Thus, when the sub undulation gate is standing or lying down, the operation roller 16 always supports the rolling surface 17 of the vertical beam 14 of the door body 4 of the main undulation gate tilted downstream so as to lean on this. Therefore, the main undulation gate will also stand up or surrender.

Now, in the main undulation gate and the sub undulation gate installed in this way, the upper part of the hydraulic jack 50 is moderately attached to the bottom of the water channel at a position sufficiently upstream of the shaft 23 of the door body 21 of the sub undulation gate. The roller 52 at the tip of the rod 51 is installed in such a posture that the steel plate 27 on the lower surface of the door body 21 is pushed up by being inclined downstream. After that, the oil feeding pipe 53 connected to the hydraulic jack 50 is led to the land by burying it in the concrete of the water channel, etc., and the hydraulic valve, the fall valve 54, the fall flow regulating valve 55, the standing valve 56, and the standing flow regulating valve of the hydraulic operating device. 57, hydraulic pump 58, and oil tank 59 are connected as shown in FIGS.

Then, as a result of hydraulic oil being pressed into the hydraulic jack 50 from the oil tank 59 via the hydraulic pump 58 via the rising flow rate adjusting valve 57, the rising valve 56, and the oil feed pipe 53, the hydraulic jack 50 is extended and the tip of the rod 51 is extended. The roller 52 pushes up the steel plate 27 on the lower surface of the door body 21 of the sub undulation gate to erect the door body 21, and as a result, the operation roller 16 pushes up the rolling surface 17 of the door body 4 and the door body 4 stands up. FIG. 3 is a sectional view of FIG.

At this time, the anchor bolt 42 is connected to the bottom of the water channel upstream of the hydraulic jack 50 with the other end of the belt 41 made of rubberized cloth having sufficient strength with one end fixed by the bolt 39 and the holding plate 40 on the upper lower surface of the door body 21. And the presser plate 43, the door body 21 is stopped by the tension acting on the band 41. That is, the operation roller 16 is not in contact with the roller stopper 18 at the upper end of the stringer 14 of the door body 4. The roller stopper 18 is provided as a safety measure when the belt 41 is damaged.

In FIG. 3, the pressure of the water dammed up upstream by the door body 4 and the weight of the door body 4 are supported by the operation roller 16, although the door body 4 tries to fall down clockwise by the shaft 6. This operation roller 16 is rotatably attached to the tip of the door body 21, and an angle at which a line connecting the rolling surface 17 of the stringer 14, the center of the operation roller 16 and the center of the shaft 23 of the door body 21 intersects.閘 is set larger than 90-. Therefore, the force applied to the operation roller 16 by the door body 4 acts to cause the door body 21 to fall down counterclockwise by the shaft 23. However, since the hydraulic jack 50 extends by being pressed with hydraulic oil between the water channel bottom and the steel plate 27 of the door body 21, the roller 52 at the tip of the rod 51 pushes up the steel plate 27 to support the door body 21. The whole stands up stably.

On the other hand, the hydraulic pump 58 is stopped, the upright valve 56 is closed, the fall valve 54 is opened, and the hydraulic oil having the pressure inside the hydraulic jack 50 is controlled via the oil feed pipe 53 while being controlled by the fall flow rate adjusting valve 55. As a result of the hydraulic jack 50 being reduced by returning to the oil tank 59, the support by the roller 52 at the tip of the rod 51 is lost and the door body 21 of the subsidiary undulation gate falls down, and as a result, the door that has lost support by the operation roller 16. FIG. 4 is a cross-sectional view of the body 4 lying down. At this time, since the operation roller 16 is supported by the base 44, the door body 21 is supported by the operation roller 16 and the shaft 23, and the door body 4 is supported by the operation roller 16 and the shaft 6. Since the surfaces of the water stop plates of the door body 4 and the door body 21 have an appropriate inclination from upstream to downstream, water and earth and sand can flow without trouble. At this time, the water leakage generated below the door body 4 and the door body 21 is discharged downstream of the undulation gate by the drain hole 45, and there is no problem.

The other side of the rubber plate 9, which can be raised and lowered and is attached to the upper surface of the anchor metal 2 by a bolt 7 and a holding plate 8, is attached to the lower portion of the door body 61 by a bolt 10 and a holding plate 11. The main undulation gate is formed by preventing water leakage between the anchor hardware 2.

The door body 61 includes a water stop plate 62 that directly receives water pressure, a cross beam 63, a vertical beam 64, and a bearing 65 in the upper part of the vertical beam, and the bearing 65 has a bearing 68 of the auxiliary flow guide plate 67 by a shaft 66. The auxiliary flow guide plate 67 is assembled so as to be freely rotatable, and projects downstream of the flow guide plate 69.
At this time, the opposite side of the water stop plate 62 of the stringer 64 is the rolling surface 17 of the operation roller 16 that controls the standing or falling of the door body 61.
Further, the tip 70 of the auxiliary flow guide plate 67 is supported and stabilized by the sliding member 71 on the upper surface of the door body 21 of the auxiliary hoisting gate.

A bearing 20 of the support base 19 installed on the bottom of the water channel at an appropriate amount on the downstream side of the main undulation gate and a bearing 22 at the lower end of the door body 21 of the sub undulation gate are assembled by a shaft 23 so as to be freely rotatable. The upper surface is inserted under the door body 61 of the main raising / lowering gate, and the rolling surface 67 of the stringer 64 of the door body 61 of the main raising / lowering gate is supported by the operation roller 16 that is rotatably attached to the tip. Yes.
In this embodiment, the relationship between the door body 21 of the auxiliary undulation gate, the hydraulic jack 50, the roller 52 at the tip of the rod 51, the oil feeding pipe 53, and other hydraulic operation devices is the same as that in the embodiments of FIGS. Therefore, the door body 61 of the main raising / lowering gate stands by the extension of the hydraulic jack 50, and the door body 61 of the main raising / lowering gate can fall down and function as the raising / lowering gate by reducing the hydraulic jack 50.

In this embodiment, the auxiliary flow guide plate 67 is rotatably attached to the upper part of the door body 61 of the main undulation gate, so that the upper surface of the door body 21 of the sub undulation gate passes over the door body 61 of the main undulation gate. I was able to relieve the intensity of the flowing water.
In the undulating gate shown in this embodiment, in the standing state of the door body 61 of the main undulating gate, the contact portion of the operation roller 16 at the tip of the door body 21 of the auxiliary undulating gate with respect to the door body 61 of the main undulating gate is main.
