Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This device is designed to raise the water level of the irrigation canal to take in agricultural water from the irrigation canal, and at the same time, release excess water over the upper part of the gate, and when there is a non-irrigation period or heavy rainfall. The present invention relates to a small undulating gate used for the purpose of overturning and allowing the running water to flow down without obstacles.

[0002]

[Prior art]

 Conventionally, as a gate used to raise or discharge the water level of an irrigation canal in this way, the undulating gate method is easy to remove the flow and the water level on the weir is easy to adjust. Since it has many advantages such as low construction cost, various types are used.

That is: 1) A wire rope is attached to one or both sides of the undulating door body to provide a wire rope type opening and closing device on the ground, and the wire rope is wound up and rewound to raise or fold the undulating door body. What makes me. 2) A hydraulic jack is installed in the pocket on the downstream side of the undulating door body to pump hydraulic oil to the hydraulic jack. When the hydraulic oil is extended, the undulating door body stands up, and conversely the hydraulic oil from the hydraulic jack. The hydraulic jack contracts when the valve is opened to push out the undulating door body. And so on.

[0004]

[Problems to be solved by the device]

 Certainly, the methods of 1) and 2) make it easy to eliminate the flow of water, and it is easy to adjust the water level above the weir, and construction costs are higher than those of pull-up gates (slide gates and roller gates). Although it is possible to use the advantages of the undulating gate system, such as low cost, and the application effect is sufficiently enhanced, a) For small undulating gates with a waterway width of 2 m or less and a weir height of 1 m or less However, the cost of installing the wire rope type opening / closing device and hydraulic operating device on the ground is large compared to the work cost of the undulating doors and door supports, and the work cost is high. B) In the case of using a waterway as a road, such as an irrigation canal installed parallel to the road, it is difficult to deal with cases where it is not possible to install a switchgear or operating device on the ground. C) The concrete structure of the irrigation canal where the gate will be installed becomes complicated, and the cost and period of civil engineering work will be long, and a long construction period will be required for gate construction. Become. There are still many problems to be improved.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional example, and aims to provide a small undulating gate in which the drainage is easily eliminated, the water level on the weir is easily adjusted, and the construction cost is very low. To do.

[0006]

[Means for Solving the Problems]

 That is, the small undulating gate of the present invention is characterized by being configured as follows. 1) An undulating gate is installed on the floor of the canal by providing a drop with a properly lowered downstream side and by providing vertical grooves on both side walls of the canal so that the drop matches the upstream end. 2) On the other hand, in the vertical grooves of both side walls of the canal, side groove steel is used so that the rear surface is aligned with the surface of the side wall of the canal and the projecting edge is housed in the vertical groove of the side wall. A watertight rubber mount that matches the height of the upstream side of the above, a deposit that also functions as a connecting material for side channel steel, and an upper connecting material that connects the left bank and right bank above the side channel steel. A gate frame is constructed by doing so, and at the same time, there is a dimensional allowance between the two so that the gate frame can be inserted into the undulating gate installation part of the waterway from above or pulled up. 3) Furthermore, the rotating shaft whose position is determined by the bearing portion and the bearing material provided under the side surface channel steel material of the gate frame, has the surface of the shaft not higher than the upstream side channel floor, and the channel floor drop portion. A horizontal girder horizontally attached to this rotary shaft and a girder attached to the rotary shaft, an upper girder attached to the tip of the girder in the waterway crossing direction, and a water stop supported by the rotary shaft, girder, and upper girder. The plate and the plate form an undulating door body that undulates. 4) At this time, a part of the gate frame functions as a door stop, and the lower watertight rubber attached to the metal deposit comes into contact with the surface of the rotating shaft to secure the lower watertightness and to both sides of the water blocking plate of the undulating door. The attached side watertight rubber contacts the back surface of the lateral channel steel to form a side watertight seal. 5) Then, one end of the rotary shaft of the undulating door is extended to the inner pocket of the side wall channel steel of the gate frame, and unnecessary portions of the worm gear are cut off to make the effective angle about 90 °. Install the worm that engages with the worm, and arrange the worm shaft center line horizontally just above the rotating shaft.In addition, install a bevel gear on the worm shaft, and vertically attach the shaft of the small bevel gear that meshes with it. It is extended to the end and a handle mounting part is provided at the tip, and the operation mechanism part is constructed in the inner pocket of the side channel steel. 6) With the above configuration, by attaching the handle to the handle mounting portion of the shaft of the small bevel gear on the ground and rotating it, the rotary shaft of the undulating door body is normally or reversely rotated, and thus the undulating door body is erected or tilted. It is possible.

Since the small undulating gate of the present invention is configured as described above, the operating mechanism section for operating the undulating undulating door body is one set of worm gear and one set of bevel gear, and the rotating shaft and bearing section related thereto. Since it has only detachable handles, the number of parts is small, it is very economical, and since the undulating door body, gate frame, and operating mechanism do not all come out on the ground, removing the detachable handles eliminates obstacles on the ground. It is also convenient when using waterways as roads.

[0008] Also, when the waterway where the undulating gate is installed is constructed of concrete, it is very easy only by providing the head of the flume and the vertical groove on the side wall, and the installation of the undulating gate can be done on the gate frame at the factory. It is very economical as it only requires a short period of time and a short period of work because all that is required is to bring the undulating door and operating mechanism into a single unit, bring them to the site, and inject the sealing material after installation and adjustment.

[0009]

[Embodiment of the invention]

 An embodiment of the small undulating gate of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view (viewpoint = upstream side) when the undulating door is erected, FIG. 2 is a sectional view taken along the line EE in FIG. 1, FIG. 3 is a sectional view taken along the line ROLL in FIG. 1, and FIG. 5 is a sectional view taken along the line of FIG. 4, FIG. 5 is a sectional view taken along the line of FIG. 4, and FIG. 6 is a sectional view taken along the line of FIG. FIG. 8 is a cross-sectional view taken along line H-H in FIG. 7.

In FIG. 1 and FIG. 2, the upstream water channel bed 1 is higher than the downstream water channel bed 2 by the height h of the drop portion 3, and by utilizing this height difference, the metal deposit 4 and the rotary shaft 5 are respectively at the upper ends. The horizontal crossing of the canal is made to match the height of the upstream canal floor 1.

A sealing material 6 is injected into a gap between the metal deposit 4 and the drop portion 3 to prevent water from leaking out, and a lower watertight rubber 8 is attached to a rubber mount 7 of the metal deposit 4 by a rubber retainer 9 and a bolt 10. The lower end of the watertight rubber 8 is in contact with the rotary shaft 5 to form a watertight part of the lower part.

The vertical girder 11 attached to the rotary shaft 5 has an upper horizontal girder 12 attached to the tip thereof. The rotary shaft 5, the vertical girder 11, the upper horizontal girder 12 and the water stop plate attached to these three members. 13 together form an undulating door body.

Side watertight rubbers 14 are attached to both sides of the water stop plate 13 by rubber pressers 15 and bolts 16, and the tips of the side watertight rubbers 14 come into contact with the rear surface 18 of the lateral grooved steel material 17 and It is watertight.

The rear surface 18 of the lateral grooved steel material 17 is adjusted so as to match the side wall surface 19 of the water channel as shown in FIG. 3, and is installed in the vertical groove 20 of the lateral wall of the water channel. A seal material 21 is injected into the gap 20. The lateral channel steel members 17 installed in the vertical grooves 20 on the left and right banks of the waterway are firmly connected and joined by the deposit 4 and the lower connecting member 22 in the lower part and the upper connecting member 23 in the upper part to form the gate frame. Since it is constructed and has sufficient strength and rigidity, it is installed in a factory with an undulating door body and an operating mechanism and transported to the site as a unit, and the head of the waterway floor installed at a predetermined position in the waterway. It is possible to complete the installation by inserting it from above into the installation part of the undulating gate, which is composed of the part 3 and the vertical groove 20 of the water channel side wall whose upstream end is aligned with the drop part 3.

By the way, as shown in FIG. 4 to FIG. 6, a semi-circular arc portion supporting the upper half of the rotating shaft 5 at the lower end of the side surface channel steel 17 so that the rotating shaft 5 can be inserted from below. And a bearing plate 25 for supporting the lower half of the diameter-reduced portion 5-1 of the rotary shaft 5 on the inner pocket side of the lateral grooved steel 17 by means of the bolt nut 26. Since it is attached to the side surface channel steel 17, the position of the rotary shaft 5 is determined. Moreover, since the bearing plate 25 is supported with an adequate margin of movement in the direction of the center line, the undulating door body is attached to the gate frame so as to be able to undulate, and the position with respect to the back surface 18 of the deposit 4 and the lateral grooved steel material 17 is increased. Since the relationship is maintained properly, the watertightness of the lower and side surfaces is also stable.

Further, the required side of the right bank or the left bank is selected, and the diameter reduction portion 5-1 of the rotary shaft 5 is extended by a necessary amount so that the center comes near the center of the depth of the inner pocket of the side grooved steel material 17. Then, a fan-shaped worm gear 27 having an effective angle of about 90 ° is cut off by removing unnecessary portions, and is attached by a key 28.

The worm 29 with a shaft that meshes with the fan-shaped worm gear 27 supports a radial load with the center line thereof horizontal just above the rotary shaft 5 and a thrust load due to a hydraulic load acting on the undulating door body. The bearing 30 is supported by the bearing 30 and the bearing 31 at the opposite position, and is attached to the pocket of the side channel steel material 17.

A shaft 36, to which a small bevel gear 34 is attached by a key 35, which meshes with a bevel gear 33, which is attached to a worm 29 with a shaft by a key 32, is supported by bearings 37 and 38, and has a center line vertical. Then, it is located inside the side channel steel material 17, and has a handle mounting portion 39 machined into a regular hexagon at the upper end thereof.

The fan-shaped worm gear 27, the worm 29 with a shaft, the bearings 30 and 31, the bevel gear 33, the small bevel gear 34, the bearings 37 and 38, the shaft 36, and the handle mounting portion 39 at the upper end thereof are configured. All the operation mechanisms are protected in the inner pocket of the lateral channel steel 17, so they will not be damaged by transportation and installation work after assembly in the factory. Further, even after being installed in the waterway, the function of the undulating gate is maintained by preventing problems such as the rotating part coming into contact with the vertical groove 20 provided on the side wall.

Further, these operation mechanism portions do not project to the upper portion of the side surface channel steel material 17, and only when necessary, the regular hexagonal hole portion 41 of the handle 40 is inserted into the handle mounting portion 39 and driven. In other cases, since the handle 40 is removed, it does not cause any obstacle even when the upper part of the gate is used as a road or the like.

With the above construction, when using the small undulating gate of the present invention, it is sufficient to simply insert the hole 41 of the handle 40 into the handle mounting portion 39 and rotate the handle 40. It is transmitted to the shaft-equipped worm gear 29 via the small bevel gear 34 and the bevel gear 33, and the fan-shaped worm gear 27 rotates to enable the internal groove of the side grooved steel material 17 to rotate by more than 90 °. As a result, the rotary shaft 5 driven by the fan-shaped worm gear 27 rotates, so that the undulating door body can be operated at 90 ° from standing to falling. 7 and 8 show a state in which the undulating door body has fallen down.

Further, since the advance angle of the worm is selected so that the worm gear is self-locked, the situation in which the shaft worm 29 is rotated by the force from the fan-shaped worm gear 27 does not occur.

Therefore, the posture of the undulating door body such as standing, semi-standing, and falling can be changed only by operating the handle 40, and the function of the undulating gate is stabilized.

[0025]

[Effect of the invention]

 Since the small undulating gate of this invention is configured as described above, the undulating door body with a simple structure in which a vertical girder, upper horizontal girder, and water stop plate are attached to the rotating shaft, and a simple operating mechanism with sufficient strength and rigidity. Since it is integrally incorporated in the gate frame having the ridge, the undulating gate can be manufactured at a very low cost. Moreover, the undulating door can be directly driven without using a medium such as a wire rope or a hydraulic jack, and a very compact structure can be achieved.

In addition, since the whole assembly is assembled at the factory and the undulating gates that have been tested are carried together and installed at the predetermined positions in the water channel, the time required for installation is one day from preparation to the injection of sealing material. It will be sufficient, the construction period will be shortened, and the cost will be very low.

Furthermore, the structure of the part where the undulating gate of the waterway is installed is very simple because the head drop of the waterway floor and the vertical groove of the waterway side wall are sufficient, therefore the construction period is shortened and the cost is also low. .

As described above, since it is possible to provide an undulating gate with stable performance at a low cost to a small irrigation channel with a large number of installation locations, there is a great industrial advantage.
