Description

[Detailed description of the invention] This invention relates to a water intake device for a reservoir, etc. More specifically, a water intake ring with a float attached thereto is rotatably connected to a water pipe, and the water taken by the water intake ring is passed through the water pipe. This invention relates to a water intake device for a reservoir or the like, which releases water from a discharge hole drilled in a dam.

By the way, this type of water intake device is conventionally known.

However, in conventional water intake devices of this kind, the lower part of the water pipe (the side opposite to the side where the water intake ring is connected) is rotatably connected to the discharge pipe fixed to the dam, so the water intake device Inspection, repair, or removal of equipment had to be carried out either by removing the water from the reservoir or by choosing a season when the water level was low, which was extremely inconvenient, especially in urgent cases. .

Therefore, an object of the present invention is to provide a water intake device that minimizes wasteful discharge and allows simple and easy work when inspecting, repairing, or dismantling the water intake device.

Furthermore, the present invention enables the installation of a water intake device by using an existing dam emergency gate as is, without having to perform any special construction work to install the water intake device.

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

In Figures 1 and 2, reference numeral 1 denotes a float having an appropriate shape such as a flat cylinder, and a hole (not shown) through which water enters and exits is bored in the bottom surface of the float 1, details of which will be described later. By changing the amount of air (amount of water) in the float 1, the float 1 rises and falls, making it possible to change the water intake position (water intake depth).

At the bottom of this float 1, a trumpet-shaped water intake ring 2 is attached at intervals by several spacers 3 attached with bolts 4.

The lower part of this water intake ring 2 is a cylindrical part 5, and a T-shaped pipe 6 is provided at the lower end of this cylindrical part 5, either made integrally with this or made separately and connected with bolts. The center line of the double pipe 6 is orthogonal to the center line of the cylindrical portion 5 of the water intake ring 2.

7 and 7 are water guide pipes (in this embodiment, two water guide pipes are provided).

) The upper curved pipe portions 8, 8 of the water conduit pipes 7, 7 are rotatably connected to the T-shaped pipe 6.

Therefore, the float 1, the water intake case 2, and the T-tube 6 can be rotated together with respect to the water guide pipes 7, 7.

Further, the lower bent pipes 9, 9 of the water conduit 7.7 are rotatably connected to the T-shaped pipe 10, as shown in FIG.

As shown in Fig. 2, a reinforcing member 18 serving as a float is provided between the pair of water conduit pipes 7. The device is reinforced to avoid making it unnecessarily large.

A door body 11 has a discharge hole 12 formed therein as shown in FIG. 4, and a T-shaped pipe 10 is connected to this door body 11 by a bolt.

This door body 11 is also provided with a bracket (15.15) as shown in FIGS. 3 and 4.
A pivot portion 16.16 of the lower bent pipe portion 9.9 is pivotally connected to 15.15 by a pin 17.17.

Therefore, the water pipes 7, 7 are connected to the door body 1 to which the T-shaped pipe 10 is fixed.
It is designed to be able to rotate relative to 1.

Furthermore, the door body 11 has a retaining part which engages with the guide rail 21.21, in the embodiment shown in FIGS. 4 and 5 a roller 13.
. . . In the embodiment shown in FIG. 6, the flange 1
4.14, and the engaging portions 13..., 14.
14 engages with guide rails 21.21 and is moved up and down by the door body 11.

The guide rail 21.21 is connected to the dam 2 as shown in FIG.
A door body support 22 for supporting the door body 11 is provided at the lower end of the guide rail 21.21.

With the door body 11 shown in FIG. 1 being lowered and supported by the door body holder 22, the water conduit pipes 7, 7 are discharged from the dam 20 through the T-shaped pipe 10 and the discharge hole 12 of the door body 11. It communicates with the hole 23.

The guide rails 21, 21 and discharge holes 23 of the existing dam emergency gate can be used as they are as guide rails and discharge holes of this water intake device.

In addition, in FIG. 1, 24 is an air hole that introduces outside air into the discharge hole 23 bored in the dam 20 to prevent negative pressure vibration of the door body 11, 25 is a winch installed on the upper part of the dam 20, and 26 is a winch with one end. A wire 27 wound around the winch 25 and attached at the other end to the water conduit pipes 7, 7 is airtightly connected at one end to the float 1 and at the other end to a compressed air source (not shown), or by a switching operation. Flexible pipe opened to the atmosphere, 2
8 is a spare flexible tube, and 29 is a spare float.

Since the water intake device according to the present invention is constructed as described above, the rollers 13...
etc., and move the door body 11 to the guide rail 21゜2.
The water intake device is installed by lowering the float 1, water intake case 2, and water guide pipes 7, 7 together into the water of the reservoir, and placing the door body 11 on the door body receiver 22. Ru.

Next, when air is supplied to the float 1 through the flexible pipe 27, the water in the float 1 is expelled from the hole drilled in the lower surface of the float 1, and the float 1 floats to the surface, bringing the water intake device into the operating state shown in FIG.

As a result, water in the reservoir enters the water intake case 2, passes through the T-shaped pipe 6, the water conveyance pipes 7, 7, the T-shaped pipe 10, and the discharge hole 12 of the door body 11, and is discharged from the discharge hole 23 of the dam.

Normally, in the case of agricultural water, the water intake casing 2 is located near the water surface to take in hot water, but when drawing water with as little turbidity as possible (clean water) such as industrial water, the air inside the float 1 is connected to a flexible pipe. At step 27, water is put into the drain flow 1-1, and the water intake case 2 is submerged in the low turbidity water layer, so that low turbidity water is taken from the water layer.

When the water intake casing 2 sinks, by adjusting the length of the wire 26 connected to the water conduit pipes 7, 7 beforehand with the winch 25, the sinking will stop if the wire 26 is tensed.
The water intake housing 2 can be placed at any water depth.

The wire 26 also serves to secure the unstable position of the water intake device.

Further, in an emergency where water intake is to be stopped due to an unforeseen accident, the wire 26 is wound up by the winch 25 to raise the water intake case 2 above the water surface.

As explained above, according to the present invention, a guide rail facing the discharge hole bored in the dam is provided inside the dam, and a retaining part that engages with the guide rail is provided so that the guide rail is moved along the guide rail. A door body is provided that can move up and down and has a discharge hole that communicates with the water conduit pipe and the discharge hole drilled in the dam, and the water conduit pipe is connected to the discharge hole of the door body so that the door body can freely rotate. Since they are connected, when inspecting, repairing, or dismantling the water intake device, the door body 11 is raised along the guide rails 21 and 21, and the float 1, water intake case 2, and water conduit pipe 7 are removed.
, 7 and lower the other closing gate to close the discharge port 23.

Therefore, the stored water is released only for the time it takes to pull up this door body and lower another closing gate, but that time is extremely short and there is no wasteful release.

To install the water intake device that has been inspected and repaired, pull up the other closing gate, then lower the door body 11 along the guide rail 21.
It is sufficient to support the float 1, the water intake case 2, and the water guide pipes 7, 7 in the water, and there is no need to remove water from a reservoir or the like one by one as in the conventional case.

Therefore, according to the present invention, it is easy to pull up and lower the water intake device when inspecting the water intake device, and it is suitable for this type of water intake device.

In addition, the present invention allows the guide rails and discharge holes of the existing dam emergency gate to be used as they are as the guide rails 21, 21 and the discharge holes 23 of the dam 20, and the guide rails and discharge holes for this water intake device can be used as they are. There is no particular need to provide it separately.
