    In the conventional waterproof standard, as described above, it was a waterproof standard to which a drain hole may be provided in the bottom plate.However, in recent years, the performance of ships has improved, the navigation speed has increased, and navigation in stormy weather has become possible. The ability to withstand has increased, and therefore, the waterproof standard has been revised, and more stringent waterproof performance has been required, and the conventional structure that always opens the drain hole cannot satisfy the new standard. there were.

  In view of such conventional problems, the present invention is intended to provide a waterproof / drainage device for shiplights that satisfies more stringent waterproof performance and that is naturally drained when immersed in the lamp body. It was made.

  In order to solve the conventional problems as described above and achieve the intended object, the feature of the invention described in claim 1 is that a hollow portion in which a light source is accommodated is provided, and light from the light source is provided around the light source. The bottom wall of the lamp body having a translucent part that transmits light is provided with a drain hole that is vertically open and open, and a valve chamber is provided below the drain hole position. A drain hole that is open to the atmosphere is opened at the bottom, and a valve body made of a sponge-like water-impermeable elastic material is accommodated in the valve chamber. What is formed so as to be larger than the height of the water lamp is a waterproof / drainage device for a boat lamp in which it is accommodated in a compressed state and the drain hole is closed by an elastic force corresponding to the compression allowance of the valve body.

  According to a second aspect of the present invention, in addition to the structure of the first aspect, the valve body integrally includes a columnar body projecting on an upper surface thereof and loosely fitted into the drain hole, and the columnar body. A taper portion having a large diameter on the lower side is integrally formed at the base portion of the ridge, and the taper portion abuts on the opening edge of the drain hole to close the drain hole.

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect, the valve chamber has a bottom plate of the shiplight as a top surface and projects below the bottom plate. A ring-shaped convex part is used as a peripheral wall, and a bottom cover fitted to a lower end opening of the peripheral wall is used as a bottom face. The bottom cover integrally includes an elastic claw that engages with the peripheral wall. It is in.

  A shiplight waterproofing / draining device according to the present invention has a hollow portion in which a light source is housed inside, and a bottom wall of a lamp body having a translucent portion that transmits light from the light source around the top and bottom. The drainage hole is provided with a drainage hole that is open through, and has a valve chamber below the drainage hole position. A mouth is opened, and a valve body made of a sponge-like impermeable elastic material is accommodated in the valve chamber, and the valve body is formed in a compressed state that is formed to be larger than the height of the valve chamber. Since the drainage hole is closed by an elastic force corresponding to the compression allowance of the valve body, the drainage hole always corresponds to the compression allowance of the valve body even if a wave acts during navigation. Since it is closed by elastic force, the waterproof performance is greatly improved compared to the conventional one, and the new standard It can be assumed that the minute satisfaction.

  In addition, even when flooded under severe conditions of navigation, the valve body is pushed open by the expansion of the lamp body air when the internal temperature rises due to the lighting of the light source, and the internal water is discharged together with the exhaust gas. Is discharged.

  Furthermore, in the present invention, the valve body integrally includes a columnar body that protrudes from the upper surface and is loosely fitted into the drain hole, and a tapered portion having a large diameter on the lower side is integrally formed at the base of the columnar body. The taper portion abuts against the opening edge of the drain hole and closes the drain hole, whereby a higher sealing degree can be obtained against water pressure from the outside.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1 shows an example of a boatlight in which a boatlight waterproofing / draining device according to the present invention is implemented. In the figure, reference numeral 10 denotes a hollow lamp body. The lamp body 10 has a cylindrical translucent body portion 11, the lower end side of the lamp body 10 is connected to the bottom member 12 and closed, and the upper portion is connected to the top member 13. It connects and it has the structure where the opening provided in the top member 13 was closed with the canopy 14. The canopy 14 is fixed with a set screw 15 so that it can be opened. A light source 17 composed of a light bulb is attached to a socket fixed to the bottom plate 16 of the bottom member 12.

  The water draining devices 18 and 18 according to the present invention are respectively installed on the flat portion at the center of the bottom plate 16 of the lamp body 10 and the bottom portion of the annular groove on the periphery. 2 to 3 show a first embodiment of the water draining device. In this example, the water draining device has three drain holes 20 that are vertically opened through the bottom plate 16, that is, the bottom wall of the hollow space of the lamp body 10, and the drain holes 20 are arranged in such a manner that the drain holes 20 are opened on the top surface. A valve chamber 21 formed under the bottom plate, a drain port 22 formed in the bottom surface of the valve chamber, and a valve body 23 housed in the valve chamber 21 are configured.

  The valve chamber 21 is configured by being surrounded by a bottom plate 16, a peripheral wall 24 made of a ring-shaped convex portion having a square shape projecting from a lower surface thereof, and a bottom lid 25 constituting a bottom surface. The bottom lid 25 has locking claws 26, 26 raised integrally on both edges of a rectangular plate-shaped main body portion, which is inserted into the peripheral wall 24, and the locking step portions 27, 27 on the inner surface of the peripheral wall. It has been secured by signing on.

  In the bottom cover 25, a drain outlet 22 is opened at a position different from the horizontal position of the drain hole 20, more specifically at a position corresponding to the center of the three drain holes 20 of the bottom plate 16. Yes.

  The valve body 23 is formed of an elastic material made of a sponge-like rubber material containing closed cells, and its outer diameter is formed in a square shape that fits into the valve chamber 21. The thickness is larger than the height of the valve chamber 21 and is accommodated in the valve chamber 21 in a compressed state. Accordingly, the drain hole 20 and the drain port 22 above and below the valve body are closed by the elastic force corresponding to the compression allowance of the valve body 23.

  In the drainage device configured as described above, when an external water pressure is applied from the drain port 22, the valve body 23 is pushed up by the external pressure, acts in the direction of closing the drainage hole 20, Inundation is prevented.

  Further, the water that has entered the lamp body 10 through various drainage holes 20 and the gap between the canopy 13 and the upper end opening or the like accumulates on the bottom plate, that is, on the drainage hole 20. When the light source 15 is turned on, the temperature inside the lamp body 10 rises and the internal air is warmed and expanded to increase the internal pressure. As a result, the internal pressure acts on the valve body 23 through the drain hole 20 by the pressure. However, when the internal pressure becomes larger than the pressing force due to the elasticity of the valve body 23, the valve body 23 is deformed in the direction of opening the water drain hole 20, whereby the water accumulated at the bottom of the lamp body is discharged.

  4 and 5 show a second embodiment of the present invention. In this example, one drain hole 20 is formed in the central portion of the valve chamber in the bottom plate 16 constituting the top surface of the valve chamber 21. FIG. A columnar body 30 that is loosely fitted into the drain hole 20 is integrally formed at the center of the upper surface of the valve body 23. A tapered portion 31 having a large lower diameter is integrally formed at the base portion of the columnar body 30, and the outer peripheral surface of the tapered portion 31 abuts on the opening edge 32 of the drain hole 20 to close it. In this contact, the tapered portion 31 is slightly deformed, and the drain hole 20 is closed by a force pressing the opening edge 32 by the reaction force.

  Three drain ports 22 are formed in the bottom lid 25 at a position shifted from the horizontal position with respect to the drain hole 20, in this example, at a position at each vertex of the triangle with the drain hole 20 in the center.

    In this example, as in the example shown in FIGS. 2 and 3, the water that has entered the lamp body 10 turns on the light source 15, and the temperature inside the lamp body 10 rises and the air inside expands. As a result, when the internal pressure acts on the tapered portion 31 of the valve body 23 through the drain hole 20 and the internal pressure becomes larger than the pressing force due to the elasticity of the valve body 23, the valve body 23 is deformed in a direction to open the drain hole 20. As a result, the water accumulated at the bottom of the lamp body is discharged.
