Description

  The present invention relates to a waterproof structure for a double door of a package used in, for example, a package storage type engine generator.

  2. Description of the Related Art Conventionally, for example, in a cogeneration system, a package storage type engine generator in which related equipment such as a gas engine and a gas compressor for compressing fuel gas supplied to the gas engine is incorporated in a package is used. Such a package-accommodating engine generator has a soundproofing effect by incorporating related devices such as a gas engine and a gas compressor in the package, and has an effect of protecting the related devices from rainwater and the like when installed outdoors.

  Further, as shown in FIG. 10, the package is appropriately provided with double doors 101 and 102 for performing maintenance of components such as a gas engine and a generator built in the package 100. Summing portions 105 and 106 that overlap each other are provided at the leading ends of the double doors 101 and 102. It is necessary to prevent rainwater from entering the package 100 from the summing units 105 and 106 as well.

  Therefore, conventionally, a strip-shaped sealing material 107 is fixed to the summing portion 105 of one of the opening doors 101 on the inside. Further, the summing portion 106 of the other opening door on the outside is formed by thinning the door, and can be brought into close contact with the sealing material 107 from the outside.

  However, the conventional double doors 101 and 102 have the seal material 107 and the other open door 102 so that the other open door 102 can be smoothly opened and closed with respect to the one open door 101 to which the seal material 107 is fixed. A slight relief gap 108 is formed between the step surface 102a in the width direction. Therefore, an opening communicating with the inside of the package 100 is formed on the upper surfaces of the summing portions 105 and 106. As a result, there is a problem that rainwater that falls on the upper surfaces of the double doors 101 and 102 enters the package 100 through the upper surface opening of the escape gap 108.

  A waterproof structure for preventing rainwater from entering from the upper surface of the summing portion of such a double door is known (see, for example, Patent Document 1). That is, in the waterproof structure of the double door described in Patent Document 1, as shown in FIG. 11 (a), the one door 101 is formed with a ridge composed of a drainer 110 and a vertical drainer 111. In the other opening door 102, the facing side plate 102 b faces the one opening door 101 and is cut in accordance with the drainer 110 of the one opening door 101, and the front end portion is bent in a U-shape and parallel to the door surface. A flange portion 102c is provided.

  Moreover, as shown in FIG. 11 (b), an upper collar 112 is provided on the front edge of the package 100. In the state where the double doors 101 and 102 are closed, the upper drainer 110 of one of the doors 101 is positioned above the upper jar 112 so that rain water falling on the upper drainer 110 flows into the upper jar 112. ing.

JP 2008-236872 A

  However, the waterproof structure of the double door described in Patent Document 1 is such that the drainer 110a is separated from the upper rod 112. For this reason, there is a possibility that rainwater that has fallen on the drainer 110 enters the package 100 from the tip 110a of the drainer 110 along the lower surface. Further, when the amount of rainwater flowing through the upper ridge 112 is large, rainwater overflowing from the upper ridge 112 may fall through the gap between the upper drainer 110a and the upper ridge 112 and enter the package 100.

  For this reason, the waterproof structure of the double door described in Patent Document 1 is difficult to be adopted particularly for a package that is installed outdoors and that includes related equipment such as a gas engine or a gas compressor that is exposed to wind and rain. It is.

  Then, this invention makes it a subject to provide the structure which prevents the rain water invasion of the summoning part of the double opening package doors, such as an engine generator, reliably.

  The present invention has been made to solve the above-described problems, and includes a double door that opens and closes an opening provided on a package wall surface, and a double door of a package in which a sealing material is provided on the four sides of the opening and the summing portion of the double door. In the waterproof structure, the summing portion of the other opening door located on the outer side is provided with a first sealing material that contacts the summing portion of the one opening door located on the inner side, and is in a contact point with the upper side of the double doors and A second sealing material is provided on the package wall surface side above the four-side sealing material provided on the four sides of the opening, and a convex portion projecting inward of the package is provided on the summing portion located on the outer side and on the upper side of the other opening door. Provided, and when the double door is closed, the convex portion bites into the second sealing material, and the upper surface of the double door is lowered from the summing portion toward the hinge supporting the double door, In that inclined to become lower toward the di-outward direction.

  In the present invention, when the double door is closed, the gap between the summing portions is minimized by the first sealing material, and the convex portion provided on the upper side of the other opening door located above the summing portion. However, in order to bite into the second seal member provided in the package, a convex portion can form a kind of umbrella above the summing portion, and reliably prevent rainwater from entering the summing portion of the double-open package door. it can.

  Furthermore, since drainage is improved by the inclination of the upper surface of the double door, it is possible to reduce the retention of rainwater at the upper part of the summoning portion.

  The present invention minimizes the gap of the summing portion by the first seal material, and the convex portion on the upper side of the door extends into the second seal member over a predetermined range from the summing portion. A kind of umbrella can be formed, and rainwater intrusion can be reliably prevented at the summing part of the double package door.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 9 show an embodiment in which the present invention is adopted in a package storage type engine generator of a cogeneration system.

  FIG. 8 is a perspective view showing a package storage type engine generator according to this embodiment, and FIG. 9 is a front view thereof. The package 1 of the package-accommodating engine generator includes a lower package 10 made of a substantially rectangular parallelepiped casing that is grounded, and an upper package 20 that is placed on and coupled to the upper surface of the lower package 10.

  In the lower package 10, there are a gas engine 2, a gas supply unit 3, a generator (not shown), a gas valve unit 5, a high-pressure panel 6 that can be connected to an external device to supply power generated by the generator, etc. Related equipment is installed.

  In the vicinity of the gas engine 2, a lubricating oil circulation tank 7 in which lubricating oil supplied to the gas engine 2 is stored, and a lubricating oil supply tank 8 for replenishing lubricating oil to an oil pan (not shown) of the gas engine 2, Is provided.

  The upper package 20 includes a central duct 21, an intake duct 22 fixed to one end of the central duct 21 and provided with an intake hood 23, and a ventilation duct 25 fixed to the other end of the central duct 21 and provided with a ventilation hood 26. It is constructed integrally.

  The intake duct 22 is provided with an intake fan (not shown), and an air filter 9 is provided in the lower package 10 and on the intake side. The outside air sucked from the intake hood 23 by the intake fan passes through the air filter 9 and is supplied to the gas engine 2 and cools related equipment such as the gas engine 2 and the gas supply unit 3 and then the ventilation duct. It is discharged from the ventilation hood 26 via 25. Reference numeral 28 denotes a deodorizing catalyst built in the central duct 21.

  On the wall surfaces (front and rear surfaces and both side surfaces) of the lower package 10, double doors 11 and 12 for performing maintenance of components such as the gas engine 2 and the generator built in the package 1 are appropriately provided. .

  The double doors 11 and 12 are shown in FIGS. In other words, the front and rear surfaces and both side surfaces of the lower package 10 are appropriately formed with openings 10a communicating with the inside and outside of the package, and double doors 11 and 12 for closing the opening 10a so as to be opened and closed are provided at a plurality of locations. . In addition, the code | symbol 14 shown in FIG. 9 is a single opening door.

  A frame 18 made of a rectangular metal plate is provided along the four sides of the opening 10a. A four-side sealing material 30 made of an elastic member such as rubber is fixed to the four sides of the opening of the frame body 18.

  The bases of the double doors 11 and 12 are supported on the frame 18 by hinges 13 and 13. And the summing parts 15a and 15b are provided in the free end side of the double doors 11 and 12, respectively.

  A summing portion (a portion that becomes an inner side when the door is closed) 15a of one of the opening doors 11 is formed of an L-shaped band plate attached to the tip of one of the opening doors 11.

  The summing portion 15b of the other opening door 12 is located outside the summing portion 15a of the one opening door 11. The summing portion 15b of the other opening door 12 includes a thin portion formed with a step surface 15c by reducing the thickness of the tip of the other opening door 12.

A first seal member 17 having a rectangular cross section and a belt shape made of an elastic member such as rubber that is in close contact with the step surface 15c is fixed to the inner surface of the summing portion 15b over the entire length of the other opening door 12 in the vertical direction. ing. As shown in FIG. 2A, the thickness of the first sealing material 17 is
When the double doors 11 and 12 are closed, the thickness is set so as to be in close contact with the summing portion 15a of one of the open doors 11 from the outside and to be elastically deformed and compressed. In addition, since the 1st sealing material 17 closely_contact | adheres to the level | step difference surface 15c of the summing part 15b, the sealing performance is ensured between both the 1st sealing material 17 and the level | step difference surface 15c.

  Further, as shown in FIGS. 1B and 1C, the second sealing material 32 made of an elastic material having a rectangular cross section along the upper side corner portion 18 a of the frame 18 extends over the entire length in the left-right direction of the frame 18. Is provided. The second sealing material 32 is in contact with or close to the upper surface of the four-side sealing material 30 fixed to the frame 18 and overlaps the upper portion of the first sealing material 17.

  On the upper side of the other opening door 12, a convex portion 35 protruding in the package inner direction is provided. The convex portion 35 is fixed to the other opening door 12 by welding, for example. The convex portion 35 has rigidity and is configured to bite into the second sealing material 32 from the outside when the double doors 11 and 12 are closed.

  Further, the width L of the convex portion 35 is not particularly limited as long as it can cover the summing portions 15a and 15b (at least above the first sealing material 17). Specifically, as shown in FIGS. 2A, 2 </ b> B, and 6 </ b> A, the width of the opening door 12 is approximately 3 minutes from the tip of the other opening door 12 toward the hinge 13. 1 is set. The convex portion 35 can be provided over the entire width of the other opening door 12, but when the convex portion 35 is set to an appropriate length, it will remain within a predetermined range from the summing portion 15b. There is an advantage that an increase in the manufacturing cost of the hinged door 12 can be suppressed.

  In addition, by adopting a configuration in which the convex portion 35 bites into the second sealing material 32, the convex portion 35 protrudes from the first sealing material 17 and the summing portion 15 a toward the package 10, and the convex portion 35 is a kind. Since the function of the umbrella is exhibited, there is an effect of reliably closing the upper surfaces of the summing portions 15a and 15b.

  Although a slight gap is formed between the ends of the double doors 11 and 12, the summing portions 15a and 15b are sealed with the first sealing material 17 even if rainwater enters the gap. Therefore, rainwater does not enter the package 1.

  Further, as shown in FIG. 1B, the thickness direction of the upper surfaces 11a and 12a of the double doors 11 and 12 is an inclined surface having a predetermined angle α1 so as to decrease toward the outside. Moreover, the inclined surface 18d having a predetermined angle α2 is set so that the horizontal direction of the upper side of the frame 18 that contacts the double doors 11 and 12 becomes lower from the summing portion center 18c toward the hinge 13 as shown in FIG. 18d. In addition, the upper surfaces 11a and 12a of the double doors 11 and 12 are inclined surfaces that become lower in the left-right direction so as to be along (opposed to) the inclined surfaces 18d and 18d.

  Thus, by tilting the upper surfaces 11a, 12a of the double doors 11, 12, the drainage of rainwater that has fallen on the upper surfaces 11a, 12a is improved, and rainwater stays above the summing portions 15a, 15b. Can be reduced.

  Next, the operation of the double doors 11 and 12 of the package storage type engine generator configured as described above will be described.

  First, the case where the double doors 11 and 12 are closed from the opened state will be described. When one of the opening doors 11 is closed, the back surface of the one opening door 11 is in close contact with the four-side sealing material 30 provided on the frame 18, so that the three sides of the one opening door 11 (upper and lower sides and hinge side) The vertical side) is sealed. Further, the second sealing material 32 is also in close contact with the back surface of the one opening door 11.

  Further, when the other opening door 12 is closed, the three sides of the back surface of the other opening door 12 are in close contact with the four-side sealing material 30 as described above. Moreover, the first sealing material 17 provided in the summing portion 15b of the other opening door 12 comes into close contact with the summing portion 15a of the one opening door 11 that is closed from the outside. Thereby, both summing parts 15a and 15b will be sealed.

  Further, the convex portion 35 bites into the second sealing material 32 from the outside (see FIG. 1B), and the back surface of the opening door 12 where the convex portion 35 is not provided is connected to the second sealing material 32. Adhere closely (see FIG. 1C). Thus, since the convex part 35 bites into the second seal member, a kind of umbrella can be formed above the summing parts 15a and 15b, and the summing parts 15a and 15b of the double doors 11 and 12 can be formed. Infiltration of rainwater can be reliably prevented.

  When such a package storage type engine generator is installed outdoors, it will be exposed to wind and rain. Rainwater tends to enter from the front surface of the double doors 11 and 12 through the gap between the upper surfaces 11a and 12a of the double doors 11 and 12 and the inner peripheral surface of the frame 18 (the periphery of the opening 10 of the package 1) due to strong wind. In such a case, rainwater that has entered from this gap is blocked by the sealing structure of the summing portions 15a and 15b, and the upper surfaces 11a and 12a of the double doors 11 and 12 are inclined surfaces that become lower in the front side and in the left-right direction. Therefore, the blocked rainwater easily flows from the double doors 11 and 12 to the outside due to the inclined surfaces of the double doors 11 and 12. For this reason, drainage becomes favorable and it can reduce that rainwater retains in the upper part of the summoning parts 15a and 15b.

  When the double doors 11 and 12 are opened, since the first seal material 17 is provided on the other open door 12 side, the other open door 12 is opened with respect to the one open door 11 being closed. However, the 1st sealing material 17 does not become trouble. Moreover, since the convex-shaped part 35 which bite into the 2nd sealing material 32 is easily spaced apart from the 2nd sealing material 32 by the opening operation | movement of one opening door 11, it can open one opening door 11 smoothly. it can.

  The present invention is not limited to the above-described embodiment. For example, the widths in the left-right direction of the double doors 11 and 12 may be the same or different.
