Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water stop structure for a water channel. More specifically, the present invention relates to a water blocking structure including a water blocking plate and a water blocking frame used in a general drainage channel or a water channel for melting snow.

[0002]

2. Description of the Related Art For drainage channels for general use, water channels for melting snow, etc.
It is well known to provide a water stop plate in a water channel for stopping water.

These water stop plates are provided by dropping them from above into a drop groove provided on the side surface of the water channel. By dropping the water stop plate, the flow of water containing snow and ice in the waterway is finely chopped, and it acts to melt the snow and ice.

Generally, since the water blocking plate is dropped into a drop groove in an external water channel, the width of the water blocking plate is made narrower than the width of the groove so that the water blocking plate can be easily dropped.

[0005]

However, in the conventional water stop plate, a gap is easily formed between the water stop plate and the groove, and water leakage easily occurs from the gap, and therefore, the ability to melt snow or ice is required. There was a problem of turning upside down.

[0006] Further, if it is attempted to narrow the gap between the water blocking frame and the water blocking plate in order to reduce water leakage, there is a problem that the water blocking plate does not easily fall into the water blocking frame.

[0007]

The water stop structure for a water channel according to the present invention comprises:
It consists of a water stop frame attached to both side walls of the water channel and a spring-like body attached to the inner wall in the longitudinal direction of the water channel, and a water stop plate provided with elastic body frames on both side parts. I was able to drop it in.

Further, the water-stop structure for a water channel according to the present invention is mounted on both side walls of the water channel, and a side wall water-stop frame in which a spring-like member is attached to an inner wall with respect to the longitudinal direction of the water channel, and a bottom surface of the water channel. It consists of a water stop frame consisting of a bottom wall water stop frame with a spring-like body attached to the inner wall in the longitudinal direction, and a water stop plate provided with elastic body frames on both sides and the bottom. It can be dropped into a water frame.

The spring-like body is a leaf spring.

[0010]

The water-stop frame is provided with a spring-like body such as a leaf spring on the side wall and the inner surface of the side wall and the bottom surface in the longitudinal direction of the water channel.
Further, elastic bodies are provided on both sides or both sides and the bottom of the water blocking plate.

When the water blocking plate is dropped into the water blocking frame from above, the water blocking plate is pushed by the spring-shaped member to the side opposite to the spring-shaped member, and the elastic body of the water blocking plate comes into close contact with the water blocking frame. So water does not leak easily.
