Description

[Detailed description of the invention] This invention relates to a diagonal gutter installed on a slope of a river.
By attaching a swash plate to the -L portion of the door body for scraping off the earth and sand that accumulates in the door guide shutter groove, the door body can be smoothly raised and lowered.

The slope of a river is generally sloped, and when installing a sluice gate, it is advantageous to install the sluice gate diagonally instead of excavating the slope.

In other words, if a slope is excavated and a sluice gate is installed vertically, the construction cost for the excavation will not only increase, but the excavation will shorten the infiltration path length of the embankment, increasing water leakage, and will also damage the river's natural environment. As the shape of the sluice gate is artificially changed, the water flow becomes turbulent and creates eddies, which can damage the slopes and incidental facilities near the sluice gate.

However, if the sluice gate is installed diagonally to form a slanted gutter, earth and sand will easily accumulate in the door guiding groove on the upper part of the door, and the accumulated earth and sand will prevent the door from sliding up and down the door groove. However, diagonal gutters are not generally adopted due to their fatal drawbacks, which make them difficult or impossible to use.
In reality, the slopes were excavated and installed exclusively vertically.

The present invention has been developed in view of these points, and by attaching a swash plate to the top of the door body to scrape off the earth and sand that accumulates in the door guide shutter groove, the door body can be moved along the door groove. When the door is raised, this swash plate is used to scrape off the dirt that accumulates in the door groove while raising the door.In this way, the door body can be raised and lowered smoothly. .

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of a river, in which a diagonal gutter 1 is diagonally installed on an inclined slope, and a water conduit 2 is also provided.

FIG. 2 shows a front view of the diagonal gutter, and FIG. 3 shows a cross-sectional view of the same, in which the door body 3 is slid in the door groove 6 along the slides 5 and 5' by the operation of the hoisting machine 4. It is designed to rise and fall.

A swash plate 7 is attached to the upper end of the door body 3, and this swash plate 7 is connected to a pin rack 13 via a contact plate 8.

The swash plate 7 is disposed obliquely on the upper part of the door body 3 so that its lower end abuts one end -I of the door body 3 and its upper end abuts the bottom surface of the door groove 6.

Guide plates 9 and 9' for guiding the door body 3 are provided on both sides of the lower part of the door groove 6, and a cover 10 having a length that does not cover the water intake is provided on the upper surface of the door groove 6. Screw 1
1 (see the dashed line), and a stopper 12 for positioning the door body 3 is provided at the F end.

Note that this cover 10 is desirably made of an elastic material.

This diagonal gutter is constructed as described above, and since the door groove 6 is covered with the cover 10, earth and sand cannot enter into the door groove 6.

7 difficult. However, even if the cover 10 is attached, it is not possible to completely prevent the infiltration of earth and sand, and the earth and sand enters and accumulates in the door groove 6 especially due to floods.

Such accumulated earth and sand makes it difficult or impossible for the door body to slide up and down as described above, but since the swash plate 7 is attached to the upper part of the main door body 3, the hoisting machine 4 cannot be moved up and down. When the door body 3 is pulled up by the operation, the door body 3 smoothly moves up along the door groove 6 while easily scraping off the sand deposited in the door groove 6 by the upper swash plate 7.

In this way, since the swash plate 7 is attached to the -11 part of the main gutter body 3, even if there is accumulated earth and sand in the door gutter 6, it will not be difficult or impossible to raise and lower the door body 3. do not have.

Furthermore, even if dirt enters the door groove 6 during a flood, the dirt tends to fall down along the swash plate 7, so there is an advantage that it is difficult for the dirt to accumulate on the upper part of the door body 3.

In particular, when the above-mentioned cover 10 is not attached, an extremely large amount of earth and sand will enter the door groove 6, but since most of this intruding earth and sand will fall and flow down along the swash plate 7, the amount of accumulated earth and sand will be small. , even if a little bit of earth and sand accumulates, the gutter body 3 will not touch the swash plate 7.
As a result, it is possible to move smoothly up the inside of the doorway 6 while scraping off the accumulated earth and sand.

In this way, the cover 10 does not necessarily need to be attached to this diagonal gutter.

As explained above, the slanting gutter according to the present invention has a swash plate for scraping off accumulated sand on the top of the door body, and the upper end of the swash plate is attached to the bottom of the door groove for guiding the door body. Even if earth and sand accumulates in the door groove for guiding the door body, the door body can be smoothly raised and lowered.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, in which Fig. 1 is a cross-sectional view of a river, Fig. 2 is a front view of a sluice gate, and Fig. 3 is a side view of the same.
