Description

  The present invention relates to a fuel cell housing case.

  Conventionally, as this type of fuel cell storage case, a case in which a storage space for storing the fuel cell is formed by a combination of a flat cover or the like has been proposed (for example, see Patent Document 1). The housing case is supported on a frame having four support columns to form a bottom of the housing space, side covers attached to the left and right of the partition plate, a front cover attached to the front of the partition plate, A rear cover attached to the rear of the partition plate, and a top cover attached to an upper end of each cover so as to be supported by the side cover, the front cover, and the rear cover. In this housing case, when the operator performs maintenance of the fuel cell, the top cover is first removed, and then the front cover and the side cover are removed.

JP 2013-69634 A

  In the case described above, it is necessary to attach and detach at least two covers when performing maintenance of the fuel cell. Since each cover is attached by a plurality of screws or the like, the number of covers to be attached / detached is increased by one, so that the time required for attaching / detaching the cover becomes long and the maintenance workability may be lowered. For this reason, it is conceivable that the top cover is not supported by another cover, but supported by another member such as a support column extending vertically, so that the top cover need not be attached or detached during maintenance. However, if it does so, a fuel cell will be taken in and out from the opening between the support | pillars etc. which support a top cover. For this reason, in order to ensure the width required for taking in and out of the fuel cell as the width of the opening, there is a possibility that the space between the support columns is widened and the housing case is enlarged.

  The main object of the present invention is to prevent the storage case from being enlarged while improving the maintainability.

  The present invention adopts the following means in order to achieve the main object described above.

The fuel cell housing case of the present invention comprises:
A fuel cell storage case having a storage space for storing a fuel cell,
An attachment having a contact surface portion with which a back surface of a cover member that covers the opening communicating with the accommodation space contacts, and is detachably attached to an edge portion of the opening so that the contact surface portion is located on the inner side in the width direction of the opening The gist is to provide a member.

  The fuel cell storage case of the present invention has a contact surface portion with which the back surface of the cover member that covers the opening communicating with the storage space contacts, and the edge portion of the opening is positioned on the inner side in the width direction of the opening. An attachment member that is detachably attached is provided. Thereby, the width of the opening can be widened by removing the attachment member from the edge of the opening, and the fuel cell can be easily taken in and out of the opening. Further, since the width of the opening can be suppressed to a width necessary for taking in and out the fuel cell, it is possible to prevent the storage case from being enlarged. In addition, since the contact surface portion that contacts the back surface of the cover member is located on the inner side in the width direction of the opening and is not subject to the restriction of the width of the opening, the contact region of the contact surface portion is prevented from being reduced. Sealing performance can be ensured. As a result, it is possible to prevent the storage case from being enlarged while improving the maintenance workability.

  In the fuel cell housing case of the present invention, an escape portion that is recessed in the width direction of the opening is formed at the edge of the opening so as not to interfere with the fuel cell when the fuel cell is inserted and removed, and the attachment The member may be attached to an edge of the opening so as to cover the escape portion. If it carries out like this, it can cover and seal an escape part with an attachment member, suppressing that the external dimension of a storage case becomes larger than necessary with respect to the width | variety required for taking in and out of a fuel cell.

  In the storage case of the fuel cell of the present invention, a bent portion that is bent from the edge of the opening toward the back side of the storage space may be provided at a position where the relief portion is formed at the edge of the opening. Good. In this way, even if the relief portion is formed, it is possible to prevent the rigidity of the edge portion of the opening from greatly decreasing. For this reason, members, such as a top plate which covers the upper part of accommodation space, can be supported appropriately.

  In the fuel cell housing case of the present invention, the attachment member has an outer flange portion positioned on the outer side in the width direction of the opening than the contact surface portion in a state of being attached to an edge portion of the opening. The contact surface portion is formed in a stepped shape so as to protrude from the outer flange portion, and is detachably attached to the edge of the opening via the outer flange portion by a fastening member having a height that fits in the step. It may be a thing. If it carries out like this, the structure which makes an attachment member detachable is realizable, avoiding that a fastening member interferes in the back surface of a cover member.

  In the fuel cell housing case of the present invention, the attachment member has an inner flange portion positioned on the inner side in the width direction of the opening than the contact surface portion in a state of being attached to an edge portion of the opening. The contact surface portion may be formed in a stepped shape so as to protrude from the inner flange portion, and the inner flange portion may be provided with an elastic seal member having a height exceeding the step. If it carries out like this, in addition to contact | abutting with the back surface of a cover member and a contact surface part, since an elastic sealing member can be sealed also by pressing on the back surface of a cover member, a sealing performance can be improved more. .

And a plurality of cover panels 15 attached to the sides of the frame 20. The top plate 14 has a circular exhaust port 14a penetrating in the front side, and an exhaust pipe (not shown) is connected to the exhaust port 14a. A ventilation fan (not shown) is provided in the fuel cell case 10, and exhaust exhausted by the operation of the ventilation fan is exhausted to the atmosphere via the exhaust port 14a and an exhaust pipe (not shown).

  The cover panel 15 is attached to the frame 20 by screws or the like so as to cover an opening communicating with the accommodation space formed by the frame 20. The cover panel 15 includes a front cover 16 attached to the front surface, a side cover 17 (only the right side surface is shown in FIG. 1) attached to the left and right side surfaces, and a rear cover (not shown) attached to the rear surface. The front cover 16 is divided into an upper front upper cover 16a and a lower front lower cover 16b. The side cover 17 and the rear cover are not divided into upper and lower parts and are configured as a single flat plate. The front cover 16 may be configured as a single flat plate.

  As shown in FIG. 2, the frame 20 includes a total of four support members (front support member 22 and rear support member 24) extending in the vertical direction, two connecting members 26 extending in the left-right direction, and a front-rear direction. And two beam-like rail members 28 extending. The four support members are fixed to stand on the bottom plate 12 by being screwed to four brackets (not shown) fixed to the four corners of the bottom plate 12, respectively. Further, out of the total four support members, the left and right two on the front side are the front support members 22 and the left and right two on the rear side are the rear support members 24. One of the two connecting members 26 is fixed by screws so as to connect the left and right front column members 22 at a substantially intermediate position in the vertical direction, and the other one connects the left and right rear column members 24 in the substantially vertical direction. It is fixed by screwing so as to be connected in position. The two rail members 28 are fixed by screws so as to be bridged in the front-rear direction on the two front-rear connecting members 26. The power generation module 1 is arranged on the upper side of the accommodation space so as to be supported on the rail member 28, and the auxiliary machine 3 and the control unit 5 are arranged on the lower side of the accommodation space. Therefore, the power generation module 1 slides on the rail member 28 from the opening K (see FIG. 2) between the two left and right front support members 22 and above the connecting member 26 (rail member 28). In this way, it is accommodated in the accommodation space.

  The configuration of the front column member 22 will be described. FIG. 3 is an exploded view of the right front strut member 22. In addition, since the front support member 22 on the left side has the same configuration with left-right symmetry, illustration and description thereof are omitted. The front column member 22 includes a fixed column 30 that is fixed to the bottom plate 12 via a bracket (not shown), and a divided column 40 that is detachably attached to the fixed column 30, and the divided column 40 is attached to the fixed column 30. One strut member is formed. The fixed column 30 is a long member in which a lower cover attaching portion 30a to which a lower front lower cover 16b of the front cover 16 is attached and a side cover attaching portion 30b to which the side cover 17 is attached are integrally formed. . The side cover attaching portion 30 b includes an abutting surface portion 38 having an elongated surface extending over substantially the entire length of the front column member 22 so as to abut on the back surface of the side cover 17. The contact surface portion 38 is formed with a plurality of (for example, six) screw holes 38a to which the side cover 17 is screwed.

  The lower cover mounting portion 30a is formed as a convex portion that is convex forward, and the top surface is in contact with the back surface of the front lower cover 16b, and the outside of the convex portion with respect to the opening K (in FIG. An outer flange portion 33 that forms a shoulder portion on the right side and an inner flange portion 36 that forms a shoulder portion on the inner side (left side in FIG. 3) of the convex portion with respect to the opening K are provided.

  The contact surface portion 31 has a plurality of (for example, three) screw holes 31a in which the front lower cover 16b is screwed on the top surface. In addition, an insertion hole 32a through which a screw fastened to the screw hole of the bracket is inserted is formed on the side wall surface 32 on the outer side (right side in FIG. 3) of the contact surface portion 31, and the connection member 26 A plurality of (for example, two) insertion holes 32b through which screws to be fastened to the screw holes are inserted are formed on the upper end side. The contact surface portion 31 is formed so as to extend to a position slightly higher than the mounting position of the connecting member 26 disposed at the substantially central position in the vertical direction, and extends across the back surface of the front lower cover 16b and the entire length in the vertical direction. Can contact. Further, the inner flange portion 36 is formed so as to protrude inward (left side in FIG. 3) from the rear end of the inner side wall surface in the contact surface portion 31, and extends to the same height position as the contact surface portion 31. ing. A notch portion 37 that is notched so that the connecting member 26 fits is formed on the inner side wall surface of the contact surface portion 31 and the inner flange portion 36.

  The outer flange portion 33 projects outward (right side in FIG. 3) from the rear end of the outer side wall surface 32 in the contact surface portion 31 and is connected to be orthogonal to the contact surface portion 38 of the side cover attachment portion 30b. . The outer flange portion 33 is provided with a relief portion 34 that is recessed in the width direction of the opening K, leaving a part of the upper portion from a position beyond the upper end of the contact surface portion 31. In FIG. 3, the escape portion 34 is formed to be recessed so as to escape to the outside in the width direction of the opening K (right side in FIG. 3). The escape portion 34 has a length in the vertical direction that slightly exceeds the height of the power generation module 1 supported on the rail member 28. The fixed column 30 has a bent portion 35 (see an enlarged view of FIG. 3) that is bent at a substantially right angle from the edge portion of the opening K toward the back side (rear side) of the accommodation space at the formation portion of the escape portion 34. Is formed. In addition, when forming the concave hollow used as the relief part 34, the bending part 35 is notched leaving, for example, sufficient several millimeters as a part used as the bending part 35 in the left-right direction, and the bending part 35 is made after that. For example, it can be formed by bending so that the portion to be turned is folded. The fixed column 30 having such a bent portion 35 can increase the rigidity as compared with that having no bent portion. In the present embodiment, the dimension and strength of the bent portion 35 are determined so that the top plate 14 including the exhaust pipe can be supported only by the fixed column 30. The outer flange portion 33 has one insertion hole 33a through which a screw fastened to the screw hole of the bracket is inserted at the lower end side, and a screw hole 33b to which the divided column 40 is screwed is located below the escape portion 34. Two are formed at a position and a position above the escape portion 34.

  The split column 40 has an abutment surface portion 41 formed as a convex convex portion forward so that the top surface abuts the back surface of the front upper cover 16a, and the outside of the convex portion with respect to the opening K (in FIG. 3). An outer flange portion 43 that forms a shoulder portion on the right side and an inner flange portion 46 that forms a shoulder portion on the inner side (left side in FIG. 3) of the convex portion with respect to the opening K are provided. A plurality of (for example, three) screw holes 41a to which the front upper cover 16a is screwed are formed on the top surface of the contact surface portion 41. The outer flange portion 43 is formed with two insertion holes 43 a in the upper and lower directions through which a screw fastened to the screw hole 33 b of the outer flange portion 33 of the fixed column 30 is inserted. For this reason, the divided columns 40 are attached to the fixed columns 30 by screws N (see FIG. 2) at two locations above and below the outer flange portion 43. When the divided column 40 is attached to the fixed column 30, the escape portion 34 of the fixed column 30 is covered by the outer flange portion 43 of the divided column 40, and the contact surface portion 41 (top surface) of the divided column 40 and the fixed column 30 are in contact with each other. The contact surface portion 31 (top surface) is connected so as to form substantially the same surface, and the inner flange 46 of the divided column 40 and the inner flange portion 36 of the fixed column 30 project to substantially the same position on the inner side in the width direction of the opening K. It will be. The convex height of the contact surface portion 41 of the divided column 40 is sufficiently higher than the height of the head of the screw N. For this reason, when the split column 40 is attached to the fixed column 30, the screw N is prevented from interfering with the front upper cover 16a when the top surface of the contact surface portion 41 and the rear surface of the front upper cover 16a come into contact with each other. can do. Further, the split column 40 attached to the fixed column 30 can be easily removed from the fixed column 30 by simply removing the two upper and lower screws N.

  Thus, the front column member 22 of the present embodiment has a split-type configuration with the fixed columns 30 and the divided columns 40. On the other hand, the rear column member 24 is different from the front column member 22 in that the fixed column 30 and the divided column 40 are integrated without being divided. However, since the rear column member 24 includes a rear cover attachment portion to which the rear cover is attached and a side cover attachment portion to which the side cover 17 is attached with the same configuration as the front column member 22, detailed description thereof is omitted. To do.

  Next, accommodation of the power generation module 1 in the accommodation space of the fuel cell case 10 thus configured will be described. FIG. 4 is an explanatory view showing the opening width of the opening K of the fuel cell case 10. FIG. 5 is an explanatory diagram showing a state in which the power generation module 1 is accommodated in the fuel cell case 10. 4A and 5A show a state where the divided pillar 40 is attached to the fixed pillar 30, and FIGS. 4B and 5B show that the divided pillar 40 is removed from the fixed pillar 30. FIG. Indicates the state.

  As described above, the fixed column 30 has the relief portion 34 that is recessed in the width direction of the opening K. When the divided column 40 is attached, the escape portion 34 is covered by the divided column 40, and the divided column 40 is removed. If it is, the escape part 34 will be exposed. For this reason, the opening width W0 (FIG. 4 (b)) of the opening K with the divided pillars 40 removed is wider than the opening width W1 (FIG. 4 (a)) of the opening K with the divided pillars 40 attached. It will be a thing. Since the opening width W0 with the divided pillars 40 removed corresponds to the width necessary for housing the power generation module 1, it is possible to suppress the opening width W0 from becoming unnecessarily large. The external dimensions of 10 can also be reduced. In addition, after the power generation module 1 is accommodated in the fuel cell case 10, the worker attaches the divided column 40 to the fixed column 30 by screwing using a screw N, so that the upper surface of the abutting surface portion 41 of the divided column 40 is fixed. A cover 16a can be attached. The front upper cover 16a is sealed by contacting the contact surface 41 with the back surface. Further, even if the escape portion 34 for expanding the width of the opening K is formed in the fixed column 30, the contact surface portion 41 of the divided column 40 covering the escape portion 34 can have a necessary contact width. The sealing property can be sufficiently secured. For this reason, it is possible to appropriately suppress the inundation of rainwater or the like into the accommodation space, or to appropriately prevent the exhaust gas in the accommodation space from leaking to the outside. In addition, since the divided pillar 40 includes the inner flange portion 46, even if rainwater or the like is immersed inside the opening K from the contact portion between the back surface of the front upper cover 16a and the contact surface portion 41, the rainwater or the like is contained in the accommodation space. Reaching in can be suppressed.

  Further, when it is necessary to take out the power generation module 1 from the fuel cell case 10 such as when the worker performs maintenance on the power generation module 1, the worker can do the following. First, the operator removes the screw and removes the front upper cover 16a. As shown in FIG. 5A, in a state where the front upper cover 16a is removed, the power generation module 1 and various parts and members around the power generation module 1 interfere with the split pillar 40, so Can not be taken out. In addition, as various components and members, for example, a supply pipe connection portion 7 to which a supply pipe of reforming water from a reforming water supply apparatus is connected, an output terminal 9 for outputting electric power generated by the power generation module 1, and the like Is exemplified. Therefore, the operator widens the opening width of the opening K as shown in FIG. 5B by removing the upper and lower screws N and removing the divided pillars 40 in the left and right divided pillars 40. is there. Thereby, since the operator can take out the power generation module 1 without interfering with the division | segmentation pillar 40, the maintenance of the power generation module 1 can be performed efficiently. Further, as described above, the bent portion 35 is formed at the portion where the escape portion 34 of the fixed column 30 is formed, so that necessary rigidity is secured. Therefore, the top plate 14 including the exhaust pipe is supported by the fixed column 30 alone. be able to. For this reason, when removing the division | segmentation pillar 40, it can be set as the thing which does not need to remove an exhaust pipe etc. from the top plate 14. FIG.

  The fuel cell case 10 of the embodiment described above has the contact surface portion 41 to which the back surface of the front upper cover 16a covering the opening K is attached in contact, and the contact surface portion 41 is located inside the opening K in the width direction. The front column member 22 which is a part of the frame 20 is configured by the split column 40 detachably attached to the fixed column 30 (the edge of the opening K). As a result, by removing the front upper cover 16a from the contact surface portion 41 and further removing the split column 40 from the fixed column 30, the opening width of the opening K can be widened and the power generation module 1 can be taken in and out of the opening K. The workability can be improved. Further, since the width of the opening K can be suppressed to a width necessary for the power generation module 1 to be taken in and out, an increase in the size of the fuel cell case 10 can be prevented. Furthermore, since the contact surface portion 41 is located on the inner side in the width direction of the opening K, the width of the opening K is not restricted, so that the top surface (contact region) of the contact surface portion 41 is reduced. It can be suppressed to ensure the sealing performance. As a result, it is possible to prevent the fuel cell case 10 from being enlarged while improving the maintenance workability.

  The fixed column 30 is formed with a recessed portion 34 that is recessed in a concave shape so as to widen the opening K, and the divided column 40 is attached to the fixed column 30 so as to cover the escape portion 34. For this reason, it is possible to provide sealing performance by covering the escape portion 34 with the divided pillars 40 while preventing the outer dimensions of the fuel cell case 10 from becoming unnecessarily large.

  In addition, since the fixed column 30 is provided with the bent portion 35 at the place where the escape portion 34 is formed, it is possible to give sufficient rigidity to the place where the escape portion 34 is formed.

  Further, the split column 40 is formed in a stepped shape by the contact surface portion 41 and the outer flange portion 43 that is separated from the front upper cover 16a on the outer side in the width direction of the opening K than the contact surface portion 41. Is attached to the outer flange portion 33 of the fixed column 30 by using a screw N that fits. For this reason, the structure which makes the division | segmentation pillar 40 detachable is realizable, avoiding that the screw N interferes with the back surface of the front upper cover 16a.

  In the embodiment, the front strut member 22 is divided so that the power generation module 1 can be taken in and out from the front of the fuel cell case 10, but the rear strut member 24 is not limited to this, and the rear strut member 24 has the same configuration as the front strut member 22. It may be an expression.

  In the embodiment, the left and right front column members 22 are all divided, but the present invention is not limited to this, and only the left and right front column members 22 may be divided.

  In the embodiment, the bent portion 35 is provided at the position where the relief portion 34 of the fixed column 30 is formed. However, the present invention is not limited to this, and the bent portion 35 may not be provided. For example, when the top plate 14 is not connected to the top plate 14 and a large load is not applied to the top plate 14 or when the fixed column 30 has sufficient rigidity without the bent portion 35, the bent portion 35 is omitted. May be.

  In the embodiment, the relief portion 34 that is recessed in the concave shape is formed in the fixed column 30, but is not limited to the relief portion that is recessed in the concave shape.

  In the embodiment, the fixed column 30 is a part of the front column member 22 of the frame 20, but is not limited thereto. For example, when the front column member 22 and the rear column member 24 are omitted and the side cover is directly fixed to the bottom plate 12, the attachment member (the divided column 40) is attached to and detached from the front end surface of the side cover. What can be attached is possible.

  In the embodiment, the example in which the width in the left-right direction is increased as the width direction of the opening K by removing the divided pillar 40 is not limited thereto. For example, it is good also as what expands the width | variety of an up-down direction as the width direction of the opening K by removing a division | segmentation pillar.

  In the embodiment, the sealing is performed by the contact between the contact surface portion 41 and the back surface of the front upper cover 16a. However, the present invention is not limited to this. For example, in addition to the contact between the contact surface portion 41 and the back surface of the front upper cover 16a, sealing may be performed using a seal member. 6 and 7 are explanatory views showing a state in which a modified elastic seal member is attached. As shown in FIG. 7, the elastic seal member 50 has a semicircular cross section on the side in contact with the front upper cover 16a (upper side in FIG. 7), and a cavity 50a is formed inside and opposite. A fitting portion 51 that is fitted into the inner flange portion 46 of the split column 40 is formed on the side. Further, the height of the elastic seal member 50 is higher than the step between the inner flange portion 46 and the contact surface portion 41. The elastic seal member 50 is attached to the split column 40 (inner seal member 46) so that the fitting portion 51 fits into the inner flange portion 46 (FIG. 7B). Although not shown in the drawings, when the elastic seal member 50 is attached to the split column 40 and attached so that the back surface of the front upper cover 16a contacts the contact surface portion 41, the cavity 50a is elastically crushed. The seal member 50 can be brought into contact with the back surface of the front upper cover 16a while being deformed and sealed. Further, as shown in FIG. 6, the seal member of the modification includes a side elastic seal member 50 attached to the divided column 40 and an upper elastic seal member 52 attached to the support member that supports the top plate 14. It is formed integrally. The sealing performance can be further improved by attaching the elastic sealing member 52 to the upper side. The upper elastic seal member 52 may be omitted.

  As described above, in the fuel cell case according to the modified example, the split pillars 40 are located at the inner side in the width direction of the opening K with respect to the contact surface portion 41 and the front surface cover 16a away from the front surface upper cover 16a. Thus, the inner flange portion 46 is provided with the elastic seal member 50 having a height exceeding the step. For this reason, in addition to the contact between the back surface of the front upper cover 16a and the contact surface portion 41, the elastic sealing member 50 can be sealed by being pressed against the back surface of the front upper cover 16a. Can be improved.
