DRAINING TRAP FOR THE HOUSETOP}

The present invention relates to a drain trap installed on the roof of a building, and more specifically, has a drain pipe coupled to the rainwater pipe at the bottom and constitutes a hemispherical body having a hollow inner portion forming a plurality of water holes at the main surface and the lower edge. Improves the drainage effect by preventing rain water from entering the main body of the main body while preventing foreign matter from falling on the surface of the main body while allowing foreign matter to flow into the main body while foreign matters such as fallen leaves and paper are caught. In addition, the ball with the heavy weight inside is integrally connected to the bottom of the hatch which is opened and closed by using a hinge on the upper surface of the main body so that when the water surface of the rain water is kept above the hatch, the hatch is forced to rise. By opening the drainage to increase the drainage to ensure a quick and smooth drainage.

Typically, the rooftop of the building is provided with a drain hole connected to the rain pipe installed on the outside of the building in order to drain the rainwater, the drainage is equipped with a structure that combines the function of draining and drainage of foreign matter.

Conventionally, the structure installed in the roof drain is inserted into the filter net 10 of synthetic resin or metal as shown in FIG. 3 to prevent foreign substances from entering.

However, since the strainer 10 is configured to be lower than the bottom surface and formed of a cylindrical shape in which the upper part of the rainwater is completely opened, various foreign matters such as fallen leaves, paper, plastic paper, etc. on the roof are collected and accumulated and drained during rainfall. This caused the building to leak, causing questions about the effectiveness of the product itself.

The present invention has been devised to solve the problems caused by the existing drain trap as described above,

The purpose of the present invention is to allow rainwater to flow into the main body in the state of hanging foreign matter such as fallen leaves or paper, and to prevent the foreign matter from sticking to the surface of the main body so that it does not slip and block the water passage. It is to provide a roof drain trap that can improve the quick and smooth drainage by forcibly opening the hatch to increase the amount of water as the float rises as the water surface rises above the hatch.

In order to achieve the above object,

The present invention proposes a hemispherical body having a hollow inner portion having a drain pipe coupled to a rainwater pipe at the bottom and forming a plurality of water passages at the main surface and the lower edge.

In another aspect, the present invention proposes a hatch portion which is opened and closed by using a hinge on the upper surface of the body and integrally coupled to the inner surface of the hatch portion, the weight is built in.

1 is an exploded perspective view showing the configuration of the present invention, Figure 2 is an exemplary cross-sectional view showing an application state of the present invention,

The main body 1 may be made of synthetic resin or metal material. The space is formed inside and is formed in a convex hemispherical shape, and impurities such as fallen leaves, paper, and vinyl, which are floated with rainwater when the rainwater flows from the roof, are passed through. Do not cover (2) and through hole (3).

On the bottom of the main body 1, a drain pipe 4 in a state of communicating with the interior is provided by using a plurality of connecting rods 4 'and coupled to the rainwater pipe DP.

The lower part of the main surface of the main body 1 is formed through the water through hole (2) at a predetermined interval so that rain water can be introduced in a small amount of precipitation, the water level of the water through the upper portion of the water through hole (2) In the case of a relatively large amount of precipitation that rises above the height of), through-holes 3 are formed to penetrate the rainwater into the body 1.

The through hole (2) and the through hole (3) is to function as the inflow of rainwater and foreign matter filtering.

The hatch 5 is formed on the upper surface of the main body 1 so as to be openable and closed by using a hinge 5 ', and the buckle 6 is fixedly coupled to the inner surface of the hatch 5.

In addition, by accommodating the heavy material 6 ′ in the inside of the mouth 6 to impart an appropriate weight to the mouth 6, external wind is introduced through the water hole 2 or the air hole 3 so that the hatch 5. ) To prevent unauthorized opening.

The mouth 6 is not limited to a specific material, but is light in weight, and can maintain durability in moisture or climate, and may be a material.

In addition, the weight 6 'accommodated in the inside of the mouth 6 is housed in the mouth 6 in a completely sealed state, and the capacity is set so that the hatch 5 can be precisely opened at a predetermined rainwater level and has a specific capacity. It is not limited.

The open source is not limited to a specific material, but may be sufficient as long as it does not adversely affect the durability of the mouthpiece 6 chemically upon receipt.

If described in detail the operation of the subject innovation is configured as follows.

If there is no rainfall, the hatch 5 is closed as shown in the solid line of FIG. 2, and the buckle 6 is fixed to the bottom of the hatch 5 to be positioned inside the main body 1.

On the other hand, even if foreign matters such as fallen leaves, paper, and vinyl on the roof are blown by the wind and attached to the main body 1, the shape of the main body 1 is formed bulging, so it immediately slides down and passes through the through hole 2 or the through hole 3. It won't stop.

When a small amount of rainfall occurs in such a state, rainwater on the roof surface flows through the water hole 2 at the bottom of the main body 1 and is drained through the central drain pipe 4.

On the other hand, as rainfall increases, rainwater flows through the through hole (3), and in the case of a lot of precipitation where the rainwater level on the roof is kept above the hatch (5) installation surface, to prevent building safety and leakage. In order for rapid drainage is required, only the water hole (2) and the air hole (3) are insufficient to increase the amount of rainwater flowing into the main body (1), but the present invention has a water level as in the virtual line of FIG. By opening the hatch (6) by pushing up the hatch (5) upwards to open, by opening the hatch (5) a large amount of rainwater quickly flows into the main body (1) through the hatch hole quickly Drainage is possible.

The hatch 6 is closed again while the float 6 descends according to the drainage of the rainwater.

On the other hand, even if the hatch 6 is so high as to raise the hatch portion 5 is completely tilted back, the hatch 6 is fixed integrally with the hatch portion 5 there is no fear of separation and departure to the outside.

The present invention as described above solves the problem that the rainwater pipe is clogged by allowing the rainwater to flow into the interior of the main body in the state of hanging foreign matter such as fallen leaves or paper, and also the body is formed bulging so that the foreign matter adheres to the surface of the main body. It does not slip and does not block the water hole so that the water can be drained smoothly. Also, if the surface of the rainwater rises above the hatch, the hatch rises and the hatch is forcibly opened to increase the drainage. It is effective to prevent.
