DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for collecting and draining cooling water sprayed for cooling after heating by a strain relief device in an upper deck of an aluminum ship.

[0002]

2. Description of the Related Art Conventionally, on a deck surface of an upper deck of an aluminum ship, the upper deck is heated by a distortion torch using a heating torch, and then cooled by spraying cooling water.
Although the distortion of the upper deck was removed, since the deck surface of the upper deck had only a small curvature, it was difficult to collect and drain the water after cooling. Therefore, when the cooled water accumulates, the strain removing operation is temporarily interrupted, and the worker collects the cooled water using a cleaning tool and drains the water.

[0003]

However, it is conceivable that the above drainage is automatically drained by using a drainage pump or a vacuum pump. There was a possibility that the entanglement would occur and the performance would be reduced. In addition, there is a problem that if dust or spatter is sucked, the filter is clogged or the pump sliding surface is damaged. It is also conceivable to use a vacuum cleaner that is used for draining sewage and oil.However, only a small-capacity tank is equipped inside, and when the tank fills up in a short time and is discharged from the tank simultaneously with suction, the tank There was a problem that the confidential inside was not maintained and it became impossible to suck.

[0004] It is an object of the present invention to solve the above-mentioned problems and to provide a drainage device capable of collecting shallow water on the floor surface and draining the water effectively.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a drainage device according to the present invention includes a water collecting body having a water collecting hole formed on a floor surface and opening to the floor surface, and a base end. The water collecting hole is connected to the water collecting body, and the water collecting hole is connected to a water collecting fence that is arranged on the floor surface and guides water on the floor surface to the water collecting hole, and a suction pipe of an ejector to which carrier air is supplied. And a drainage hose connected to the discharge side of the ejector.

[0006]

In the above construction, the tip of the water collecting fence is arranged above the curved surface of the floor to block the spreading water and guide it to the water collecting body side. Then, the water collected on the water collecting body side is sucked up from the water collecting hole by the suction force of the ejector of the suction and drainage device, and is drained from the ejector to the drainage hose together with the carrier air.

[0007] Therefore, the water that spreads over a wide area on the floor plate is collected by the water collecting fence and is suctioned and drained by the ejector of the suction drainage device, so that shallow water can be effectively sucked up and discharged together with the air. Even if foreign matter is mixed in the water, the device is not damaged. Further, a large amount of water can be sucked and discharged for a long time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a drainage device for a strain relief device according to the present invention will be described below with reference to the drawings.

In an aluminum hull, for example, a strain relief device A for removing thermal distortion due to welding on the deck 1 of the upper deck heats the deck with a plurality of torches and then sprays cooling water to rapidly cool the deck. Thermal distortion is removed. The drainage device is for draining the water after cooling sprayed at this time, and is disposed on the lower side of the deck 1 having a slight curvature, and is provided on the water collecting body 2.
A water collecting fence 3 connected to both sides from the water collecting body 3 and having a distal end disposed on the deck 1 having a higher curvature than the water collecting body 2 and guiding water on the deck 1 to the water collecting body 2 side; The suction and drainage device 4 includes a suction and drainage device 4 disposed above the water collecting body 2 and a drainage hose 5 connected to the discharge side of the suction and drainage device 4.

The water collecting body 2 is made of bronze having a large specific gravity and is formed so as to land on the deck 1 densely. A water groove 6 is formed facing the deck 1.
A water collecting hole 7 communicating with the water collecting groove 6 at the center of the water collecting body 2.
Are vertically penetrated.

A fence mounting groove 2b is formed on the bottom surface 2a of the water collecting body 2 on the back side in the left-right direction, and the base end of the water collecting fence 3 is fitted and fixed. The water collecting fence 3 is made of a flexible material such as synthetic rubber and has some weight, and may be any member that can guide and guide water on the surface of the deck 1, and is easily available at a shipbuilding site, for example. A cabtire cable or the like is used.

The suction / drainage device 4 includes a compressor (not shown), an ejector 9 to which the air for conveyance from the compressor is supplied through an air hose 8, a suction portion of the ejector 9 and a water collecting hole 7. And a suction pipe 10 for connecting the drain hose 5 to the discharge side of the ejector 9.
Is connected. Reference numeral 11 denotes an air release valve for conveying air provided before the ejector 9 via a T-tube.

In the above construction, when the strain relief device A is performing the strain relief operation of the deck 1, the water used for cooling flows to the side of the boat with a slight curvature and is collected by the water collecting fence 3. And is guided to the water collecting body 2 side.
Then, the conveying air from the conveyer is supplied to the ejector 9 of the suction / drainage device 4 via the air hose 8, so that a suction force is generated in the suction pipe 10, and the water collecting hole 6 is formed from the water collecting groove 6. Through the suction pipe 10,
It is discharged to the drain hose 5. In this embodiment, the water is discharged from the drain hose 5 to the bucket 12, but may be connected to a drain for drain.

According to the above-described embodiment, the drainage device is used as compared with a case where a certain amount of water accumulates on the deck 1 and the drainage operation is interrupted and the strain removal operation is interrupted. Thus, the shallow water on the deck surface drained during the work can be collected by the water collecting fence 3 and suctioned by the ejector 9 of the suction and drainage device 4, and can be performed for a long time without interrupting the work. The water sucked in with the air can be efficiently drained. Further, the water collecting fence 3 and the water collecting body 2 can be easily moved and installed, and the apparatus is not damaged even if spatter or dust is mixed in the water. Bronze water collecting body 2
Has a large specific gravity and a large weight, so that it has a high degree of adhesion to the deck 1 and has an anti-rust effect.

[0015]

As described above, according to the present invention, the water spread over a wide area on the floorboard surface is collected by the water collecting fence, and the water is suctioned and discharged by the ejector of the suction and drainage device.
Shallow water can be effectively sucked up and drained together with air, and the apparatus is not damaged even if foreign matter is mixed in the water.
