Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a diagonal gutter installed on a sloped surface such as a reservoir or a waterway. Regarding the structure of the gutter.

(Problems to be solved by conventional technology and ideas) Diagonal gutters installed diagonally on sloped surfaces of reservoirs, waterways, etc. are generally relatively small and have a simple structure, and are especially suitable for use in warm areas near the water surface. Since it is suitable for taking in water, it is often installed as an agricultural water intake facility.

The applicant previously proposed an improvement to this type of diagonal gutter, which has a simple structure and is easy to handle.
No. 56-80293), this one had the disadvantage that garbage easily flowed in from the water intake. In particular, this type of diversion gutter is often installed as a facility to take in water from reservoirs or canals, but the water contains a lot of floating debris, and these debris can be removed from the water intake. There was a problem that it was easy for a large amount to flow in.

SUMMARY OF THE INVENTION The object of the present invention is therefore to provide a diagonal gutter that can effectively prevent underwater debris from entering through a water intake.

(Means for Solving the Problems) For this purpose, the present invention includes a base body 5 formed with a water intake port 6 arranged on an inclined slope, and a water intake pipe provided in the front part of the water intake port 6. 11 and this base 5
and an opening/closing plate 7 that is interposed between the base end of the water intake pipe 11 and slides on the main surface of the base 5 to open and close the water intake 6 by operating the operating handle 3,
The water intake pipe 11 has a shape bent downward, and a dust removal screen 13 is attached to the water intake pipe 11.

(Function) By configuring the diagonal gutter in this way, the structure is such that it is difficult for debris floating in the water to enter the water intake pipe 11, thereby preventing debris from flowing into the water intake 11. This is what I did.

(Example) An example of the present invention will be described below with reference to the drawings.

Figure 1 is a schematic cross-sectional view of an agricultural reservoir, and shows 1
is a diagonal gutter according to the present invention which is installed diagonally above the slope 2. 3 is an operation handle arranged on the upper part of the slope 2, and as will be explained in detail later,
By operating this handle 3, the water intake port is opened and closed. 4 is a water pipe buried behind the diagonal gutter 1. Next, the structure of the diagonal gutter 1 will be described in detail with reference to FIGS. 2 to 5.

Reference numeral 5 denotes a plate-shaped base body disposed on a concrete slope 2, and a water intake port 6 is provided on one side of the base body 5. Reference numeral 7 denotes an opening/closing plate for the water intake 6, which is attached to guide parts 8 and 9 formed on both upper and lower edges of the base body 5, and slides on the main surface of the base body 5 in the lateral direction (a, b direction). It is movably disposed on the base body 5. Reference numeral 10 denotes a guide roller protruding from one side of the opening/closing plate 7, and as will be described later, the opening/closing plate 7 slides in the lateral direction by the guiding action of this guide roller 10.

Reference numeral 11 denotes a water intake pipe, which is bent in a substantially dogleg shape, and its end is fixed to a mounting plate 12. The mounting plate 12 is attached to the guide portion 8 of the base 5,
9 by welding means or the like. The opening/closing plate 7 is interposed between the base body 5 and the base end of the water intake pipe 11.

Reference numeral 11a denotes a flared opening formed at the lower end of the water intake pipe 11, and a dust removal screen 13 is attached to the lower end. As shown in FIG. 4, the substantially doglegged water intake pipe 11 is composed of a horizontal portion 11b and a substantially vertical portion 11c that hangs downward.

Reference numeral 14 denotes an elevating rod connected to the operating handle 3, and the elevating rod 14 is slid in the vertical direction by operating the handle 3. Reference numeral 15 denotes a crank part attached to the lower part of the lifting rod 14, which is composed of a rectangular long box body 15a and a crank groove part 15b bent in a substantially S-shape formed in the long box body 15a. When the diagonal gutter 1 is assembled, the guide roller 10 is fitted into the crank groove 15b. In this state, operate the handle 3 and lift the elevator rod 1.
4 is raised and lowered, the opening/closing plate 7 is guided by the groove 15b and forcibly slides laterally on the main surface of the base body 5, opening and closing the water intake port 6 (see especially FIG. 5). 1
6 is a guide rib for the lifting rod 14.

The diagonal gutter 1 has the above-mentioned configuration, and the water intake 6 is opened and closed by operating the handle 3 and sliding the opening/closing plate 7 in the horizontal direction. When water is taken into the water pipe 4, the water intake pipe 11 having the shape described above is connected to the water intake port 6, so that garbage floating in the water does not flow into the water intake port 6. Further, since the lower end of the water intake pipe 11 is an expanded portion 11a that is expanded in a trumpet shape, a large amount of water can be smoothly sucked in. Although the above embodiment has been described using the opening/closing plate 7 that slides in the horizontal direction as an example, the sliding direction of this kind of opening/closing plate is not limited to the horizontal direction. It may also be possible to open and close the water intake by

(Effect of the invention) As explained above, the diagonal gutter according to the invention includes a base body 5 forming a water intake port 6 arranged on an inclined slope, and a base body 5 formed in the front part of the water intake port 6. The water intake pipe 11 is interposed between the base body 5 and the base end of the water intake pipe 11, and opens and closes the water intake port 6 by sliding on the main surface of the base body 5 by operating the operation handle 3. The water intake pipe 11 has a shape bent downward, and the dust removal screen 13 is attached to the water intake pipe 11, thereby reliably preventing garbage from flowing in from the water intake port 6. be able to.
