Description

[Detailed description of the invention] The invention consists of an inlet 2 formed on both sides of the lower part of the water lock body 1.
The partition wall 4 having a water outlet 5 between the water outlet 3 and the drain outlet 3 is tilted, and a valve 7 formed at the lower end by the upper and lower parts of the operation frame 6 is connected to the water outlet 5.
The operation frame 6 is provided with an annular guide portion 8 having an outer diameter approximately equal to the inner diameter of the water lock body 1, and the outer peripheral surface of the annular guide portion 8 is fitted onto the peripheral edge of the water lock body 1. This relates to a water lock that is slidable on the inner peripheral wall surface, and its purpose is to enable accurate up and down operation of the operating frame and to ensure the opening of the water outlet.
Moreover, it is an object of the present invention to provide a water lock whose guide part is not damaged.

The present invention will be explained in detail by way of examples.

In the figure, reference numeral 1 indicates a cylindrical water lock main body, and a cylindrical inlet 2 and a cylindrical drain port 3 are provided on both sides of the lower part of the water lock main body 1. An elliptical water outlet 5 is formed on the inclined partition wall 4.
is perforated.

In the figure, 6 is an operating frame, and 7 is a valve provided at the lowest end of the operating frame for closing an elliptical water outlet 5 provided in an inclined partition wall 4. The lower surface is slanted and has an elliptical shape.

In the figure, reference numeral 8 denotes an annular guide portion, which is attached to the lower part of the operating frame 6, and the outer diameter of the annular guide portion 8 is approximately equal to the inner diameter of the water lock body 1.

In the figure, reference numeral 9 denotes a lower cylinder, and a valve 7 is attached to the lower end of the lower cylinder 9 whose lower surface is inclined and has an elliptical shape.The upper part of the lower cylinder 9 is screwed into the lower part of the annular guide part 8. Alternatively, the annular guide portion 8 is attached to the lower part of the operation frame 6 by being fixed with an adhesive or the like.

By fixing the annular guide portion 8 to the lower cylinder 9 in this manner, the annular guide portion 8 can be stably attached.

In this case, the outer diameter of the lower cylinder 9 is made slightly smaller than the outer diameter of the annular guide portion 8.

By moving the operating frame 6 up and down, the water outlet 5 is opened and closed by the valve.

At this time, the annular guide portion 8 is always located within the cylindrical water lock main body 1, and when the operating frame 6 is operated up and down, the annular guide portion 8
The outer circumferential surface of the valve slides on the inner circumferential wall surface of the water lock main body 1 to move the operating frame 6 up and down in a straight line.
This allows for accurate closure.

In the above embodiment, the annular guide portion 8 is provided in the lower cylinder 9.
Although an example is shown in which the annular guide portion 8 is fixed to the operating frame 6, the annular guide portion 8 is not necessarily limited to this, as shown in FIG.
It may be fixed only to.

A water lock having the above structure is used, for example, as a water lock for a culvert in agricultural land or the like.

In the figure, 10 is a cap.

In the embodiment shown in FIG. 2, a disc-shaped example is shown as the annular guide part 8, but this disc-shaped annular guide part 8
A part or plurality of the outer circumferential parts of the annular guide part 8 may be cut out, and the outer circumferential surface of the annular guide part 8 having the notched part 11 may be slidably slidable on the inner circumferential surface of the water lock main body 1.

In this case, the valve 7 can be more reliably closed if the end of the annular guide portion 8 located at the lower end of the inclined valve 7 is not cut out and is slid onto the inner circumferential surface of the lock main body 1.

In the present invention, as described above, the operating frame is provided with an annular guide portion whose outer circumferential shape is approximately equal to the inner diameter of the water lock main body, and the outer peripheral surface of this annular guide portion can freely slide on the inner peripheral wall surface of the water lock main body. Therefore, when moving the operating frame up and down, the operating frame is guided by the annular guide section and moves up and down in a straight line.As a result, even if the water outlet is slanted, the water is discharged reliably. It has the advantage of being able to close the water inlet, and since the outer diameter of the annular guide part is almost equal to the inner circumference of the water lock body, the outer circumference of the annular guide part comes into contact with the inner peripheral wall of the water lock body, preventing movement in any lateral direction. This has the advantage that it can be reliably prevented, and since it is guided by the outer periphery of the annular guide part, a large force is not applied only to one part, making it less likely to be damaged.
