Description

[Detailed Description of the Invention] This invention relates to a water stop device such as a cylinder gate that is attached to a relative sliding portion of a gate.

Generally, the cylinder gate 1 is a cylindrical gate (IA, IB, IC...) as shown in FIG.
...1E is configured to be expandable and contractable in the upward and downward directions, and the reservoir 2
It is supported by a support arm 5 having a guide roller 4 at its tip on a support column 3 erected in the water, and is guided up and down in response to changes in the water level.

The upper end of the uppermost gate (1-I) is made into a trumpet-shaped water intake port 6 that expands outward.
The lower end of E is communicated with the buried water conduit 7.

In addition, a substantially top-shaped hollow float 8 is attached to the upper part of the water intake hole 6 of the top stage IA via a plurality of rectifying members 9.
A lifting beam 12 having a sheave 11 on which a rope 10 for gate hoisting is hung is attached to the center of the upper surface of the float 8 by a tension rod 13.

A P-type watertight rubber (not shown) for water stopping is installed between each stage gate 1A to 1E.

By the way, when attaching conventional P-type watertight rubber or similar watertight rubber to a gate, the length from the fixed part of the watertight rubber to the tip that contacts the water stop plate or the other gate body is made considerably large. ing.

Therefore, in a cylinder gate where the gate moves relatively frequently, the watertight rubber is twisted in the direction of movement as the gate moves, and this repeats, causing it to break at the bent part, causing water leakage, and the life span is short, so replacement is not frequent. become more,
There is a problem in that the replacement work requires a considerable amount of labor and time and is extremely uneconomical.

This idea was made in view of the above-mentioned circumstances, and its characteristics are that watertight rubber protection plates are attached to the front and back sides of the watertight rubber in the sliding direction, reducing the amount of bending of the watertight rubber. This is to extend its lifespan.

An embodiment of this invention will be described in detail below with reference to FIG.

FIG. 2 corresponds to section A in FIG. 1, and shows a case where the device of the present invention is employed to stop water in the middle portion of a cylinder gate.

A locking ring 21.
22 is fixed, and a guide roller 23 is pivotally attached to the upper ends of the lower games IB to 1E via a bracket 25 by a horizontal pin 24, and is brought into contact with the outer circumferential surface of the upper games IA to ID.

In addition, on the upper surface of the watertight rubber mounting ring 26 fixed to the inner circumferential surface of the upper end of the lower game) IB to 1E, a ring-shaped water-tight rubber 27 is sandwiched between the upper and lower surfaces by annular protective plates 28 and 29. It is attached by bolts 30 and nuts 31 so that the

The watertight rubber 27 has a P-shaped cross section and is bent into an almost upward shape.
It is also bent into a shape similar to that of the upper and lower surfaces of the watertight rubber 27, resulting in a flexible configuration.

The upper and lower protective plates 28 and 29 have their inner circumferential tips located above and below the inner circumferential tip of the watertight rubber 57, and the inner circumferential tips of the watertight rubber 27 are located above and below the inner circumferential tips of the watertight rubber 27. The lower protection plate 29 is allowed to deform slightly downward, and in particular, the lower protection plate 29 prevents the watertight rubber 27 from being rolled downward, thereby ensuring a water-stopping function.

Further, the protective plates 28 and 29 are preferably made of a corrosion-resistant material such as stainless steel, and are more effective because they have the required elasticity or spring action.

It should be noted that the cross-sectional shape of the honeycomb rubber 27 adopted in this invention is not limited to the above embodiment, and the shape of the protection plates 28 and 29 may also be selected in accordance with the shape of the honeycomb rubber 27.

Since the water stop device according to this invention is configured as described above, the watertight rubber 27 is flexible and has reliable and good contact with the water stop plate or the other gate body, etc., and the protection plate 28, 29 is protected from the front and back in the direction of movement,
Therefore, it does not twist, curl up, bend, or break, so it has a long lifespan.
It is extremely economical, such as reducing the frequency of replacing the water rubber, saving time and effort, and shortening the time required for regular inspection work, and has many effects, such as being able to enhance the water-stopping effect.

In the embodiment of this invention, a cylinder gate with watertight rubber that slides frequently has been described, but it can of course be applied to other gates as well.
