Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a water intake device for a reservoir.

[Prior Art] In a conventional device of this type, a water channel is buried horizontally in the embankment of a reservoir, and a gate body is provided on the outer surface of the embankment so that it can be raised and lowered via a guide rail along the slope of the embankment. The mouth of the waterway is opened and closed by lifting and lowering.

In addition, Japanese Utility Model Application Publication No. 61-23328 discloses that a water intake installed on the inside slope of a river is directed downward, and the water intake is connected to the water intake in a chain on the slope and slid laterally along the water intake. A river surface water intake opening/closing device provided with a gate body is disclosed.

[Problem to be solved by the invention] In the above-mentioned conventional technology, the opening and closing of the gates provided at the multiple water intake ports are all linked, and the turbid water containing a lot of earth and sand from the bottom of the reservoir is taken in. I had a problem. Additionally, there were concerns about poor closing of the lower door due to foreign matter getting caught in the door when the door was closed, and water leakage due to corrosion of the door.

SUMMARY OF THE INVENTION An object of the present invention is to provide a water intake device for a reservoir that can effectively block the water intake ports and open the water intake ports individually so that clean water with less sediment can be taken in.

[Means for Solving the Problems] The present invention includes a water pipe installed at an angle inside the embankment of a reservoir, a waterway connected to the water pipe,
A plurality of water intake ports provided in the water pipe, a stopper made of a corrosion-resistant material and provided in the water intake so as to be openable and closable, and a stopper made of a corrosion-resistant material provided in the water intake into which the stopper fits. The valve socket includes a valve socket for attaching the stopper, a lever bar for opening the stopper, and a support rod for supporting the lever bar.

[Function] With the above configuration, the water intake can be well closed by the stopper and easily opened by the lever. Additionally, since the water intake is installed in a water pipe installed at an angle within the embankment, water can be taken from the upper level of the reservoir, where there is less sediment.

[Embodiments] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In Figures 1 to 4, 1 is a reservoir;
A concrete frame body 3 is formed on the embankment 2 of this reservoir 1 so as to cover the embankment.
The frame body 3 has a front wall part 5 inclined along the slope 4 of the embankment 2, and a bottom wall part 6 connected to the lower end of the front wall part 5. Reference numeral 7 denotes a horizontal water channel located within the bottom wall 6 at the bottom of the reservoir 1, and the dirt sweeping opening 8 of this water channel 7 is provided with a guide rail 10 of a vertically arranged frame 9. A dirt-sweeping door 13 is provided along the dirt-sweeping door 13, which is raised and lowered via a threaded portion 12 by operating a handle 11, and the dirt-sweeping port 8 is opened and closed by raising and lowering the dirt-sweeping door 13. Reference numeral 14 denotes a water pipe located within the front wall 5 along the slope of the embankment 2, and the lower end of the water pipe 14 is connected to the water channel 7. Reference numeral 15 denotes an air vent pipe connected to the upper end of the water conduit 14, and a tip opening 15A of the air vent pipe 15 is opened to the atmosphere. 16
are a plurality of water intake ports arranged in a column in communication with the water pipe 14, and each water intake port 16 is fixed to a hole 17 provided in the water pipe 14 and is connected to the hole 18 in the front wall portion 5.
It consists of a cylindrical socket 19 made of metal such as stainless steel located inside, and a valve socket 21 made of a corrosion-resistant material such as vinyl which is screwed onto the upper part of this socket 19 by a tapered threaded portion 20. Further, filler cement 22 is charged between the inner circumferential surface of the hole 18 and the outer circumferential surfaces of the socket 19 and the valve socket 21. Further, a tapered inner circumferential surface 2 is provided in the valve socket 21 via a stepped portion 23.
A fitting socket 24 having a diameter of 4A is formed. 2
Reference numeral 5 denotes a flange formed on the outer peripheral surface of the valve socket 21. Reference numeral 26 denotes a plug made of a corrosion-resistant material such as MC nylon for opening and closing the water intake 16, and a fitting portion 2 having a tapered outer peripheral surface 27A is attached to the plug 26.
7 is provided. Reference numeral 28 is a U-shaped hanging rod, and both legs 28A of this hanging rod 28 are connected to the plug body 26.
The through end 28 is fixed with a nut 29. 30 is a seat plate fixed to the hanging rod 28. A support rod 31 is located above each water intake port 16 and protrudes from the front wall 5, and the lower end of the support rod 31 is fixed to the water conduit 14. 32
is a connector such as a chain that connects the support rod 31 and the stopper 26. 33 is a lever bar, the tip of which is connected to the stopper 26.
The plug body 26 is engaged with the hanging rod 28 of the valve socket 21, and the plug body 26 is opened by levering the support rod 31 as a fulcrum, and the plug body 26 is fitted into the valve socket 21 to close it.

Then, as shown in FIG. 2, the tip of the lever bar 33 is engaged with the hanging rod 28, and the stopper 26 is opened using the support rod 31 as a fulcrum, and in this way, the upper water intake 1
By sequentially opening reservoirs 6 and 6, water from reservoir 1 can be taken in sequentially from the upper level to the lower level. Thus, clean water with less sediment can be supplied to fields, fields, etc. from the intake port 16 through the water pipe 14 and the waterway 7. In addition, by fitting the stopper 26 into the valve socket 21, the water intake port 16 can be effectively closed. Further, the plug body 26 and the valve socket 21 can effectively stop water by fitting the tapered fitting socket 24 and the tapered fitting portion 27, and the plug body 26 and the valve socket 21 are made of corrosion-resistant material. It is possible to maintain a good water-stop state for a long time. Furthermore, since the lever bar 33 has a predetermined length, the stopper 26 can be opened from above the embankment 2.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, the slope of the water pipe may be different from the slope of the embankment, and the number of water intake ports may be selected as appropriate. The stopper and the valve socket are preferably made of a corrosion-resistant material, but may be made of metal, or the outer surface of the metal may be coated with a corrosion-resistant material.

[Effects of the invention] The invention has a water pipe installed at an angle inside the embankment of a reservoir, a waterway connected to the water pipe,
A plurality of water intake ports provided in the water pipe, a plug body made of a corrosion-resistant material and provided in the water intake port so as to be openable and closable, and a plug body made of a corrosion-resistant material provided in the water intake port and into which the plug body is fitted. The valve socket is equipped with a valve socket for attaching the valve body, a lever bar for opening the plug body, and a support rod for supporting the lever bar, so that the water intake can be easily opened and closed, and can be closed well by the plug body, and there is less sediment. It is possible to provide a water intake device for a reservoir that can take water from the water.
