Therefore, in this embodiment, the threaded receptacle 138 may be correspondingly located on the roof panel 108 such that the threaded receptacle 138 may be disposed proximal to the ledge member 158. Further, the first portion 148 of the clamp 144 may be disposed adjacent to the ledge member 158 such that upon fastening the threaded fastener 146 to the threaded receptacle 138, the ledge member 158 may be trapped between the roof panel 108 and the first portion 148 of the clamp 144.
In an embodiment as shown in FIG. 2, the threaded fastener 146 may be a hexagonal bolt. In other embodiments, other threaded fasteners 146 commonly known in the art may be used to releasably secure the roof panels 108 to the frame 106. Therefore, it may be noted that the type of threaded fasteners 146 disclosed herein is exemplary in nature and does not limit the scope of this disclosure.
In an embodiment as shown in FIG. 2, the retainer assembly 142 may further include a spring 160 and a washer 162 disposed between the clamp 144 and the threaded fastener 146. The spring 160 may be configured to axially bias the threaded fastener 146 away from the threaded receptacle 138 while the washer 162 may be configured to distribute a net force of the threaded fastener 146 on the spring 160.
In an embodiment as shown in FIG. 3, a cross section of the frame 106 may be square shaped. In another embodiment as shown in FIG. 3, the cross section of the frame 106 may be I-shaped. In an embodiment as shown in FIG. 3, the clamp 144 may further include a middle portion 164 extending between the first portion 148 and the second portion 150. In this embodiment, the middle portion 164 of the clamp 144 may be of a shape and size corresponding to the cross section of the frame 106 as shown in FIG. 3.
In other embodiments the middle portion 164 may be of a shape and size corresponding to the cross section of the ledge member 158. Therefore, a person having ordinary skill in the art may acknowledge that the shape and size of the middle portion 164 of the clamp 144 may be selected based on the cross section of the frame 106/ledge member 158. Further, the size of the middle portion 164 may be selected such that upon fastening the threaded fastener 146 to the threaded receptacle 138, the first and second portions 148, 150 of the clamp 144 abut the frame 106 and the roof panel 108 respectively thereby securing the roof panel 108 to the frame 106.

INDUSTRIAL APPLICABILITY

FIG. 4 shows a method 400 of installing a power system 100. At step 402, the method includes positioning the frame 106 around the engine 102 of the power system 100. At step 404, the method further includes positioning the roof panels 108 on the frame 106. At step 406, the method further includes positioning the first portion 148 of the clamp 144 adjacent to the frame 106. At step 408, the method further includes positioning the second portion 150 of the clamp 144 adjacent to the roof panel 108. At step 410, the method further includes axially aligning the aperture 152 of the second portion 150 of the clamp 144 to the threaded receptacle 138 of the roof panel 108. At step 412, the method further includes positioning the threaded fastener 146 within the aperture 152. At step 414, the method further includes releasably fastening the threaded fastener 146 to the threaded receptacle 138 such that the roof panel 108 is releasably secured to the frame 106.
In an embodiment, the step 404 of positioning the roof panels 108 on the frame 106 may include moving the roof panels 108 such that openings 118, 120, and 122 associated with the roof panels 108 align with the engine air system 130 and the ventilation system 124.
Conventional enclosures, such as those used in enclosing power generation systems, include large panels that are often bolted in place onto a frame 106. Hence, a position of the panels with respect to the frame 106 may be fixed. In some cases, very few panels may be used to form an entire roof or sidewall of the enclosure system. Hence, these panels may be bulky and difficult to move by an operator. Thus, variations or adjustments to the configuration of the conventional enclosures may be limited.
An engine 102, such as a gas turbine engine, may include several auxiliary devices such as ducts, and air or fuel systems connected at specific/predetermined positions on the engine 102. Further, tight tolerances may be present between relative positions of the auxiliary devices and its subsequent positions on the engine 102. Therefore, the operator may be required to adjust a position of the roof panels 108 to near exact positions in order to line up and align the openings 118, 120, and 122 with the respective auxiliary devices.
During a typical assembly process, the engine 102 may be assembled first and the associated auxiliary devices may be connected to the engine 102 later. Therefore, the openings 118, 120, and 122 associated with the engine enclosure 104 may be configured based on the specific/predetermined positions of the engine 102 at which the auxiliary devices may be connected.
During assembly of the power system 100 disclosed herein, the operator may partially engage the threaded fasteners 146 to the roof panel 108. In an embodiment as shown in the FIG. 3, a play 166 may be defined between the clamp 144 and the frame 106 upon partially engaging the threaded fastener 146 to the threaded receptacle 138 on the roof panel 108. Therefore, in this embodiment, the play 166 may allow an operator to slide the roof panels 108 in a first direction A with respect to the frame 106 (as shown by line with arrows).
In another embodiment as shown in FIG. 3, the threaded receptacle 138 may be located on the panel with an offset 168 from the edge 154 of the frame 106. Therefore, in this embodiment, the offset 168 may allow the operator to slide the roof panels 108 in a second direction B with respect to the frame 106 (as shown by line with arrows).
With reference to the preceding two embodiments, the operator may slide the roof panels 108 in one or more of the first and second directions A, B until the openings 118, 120, and 122 on the respective roof panels 108 (112, 114, and 116) line up and align with the engine air system 130, engine exhaust system 136, and the ventilation system 124. Thereafter, the threaded fasteners 146 may be fully fastened to the roof panel 108 by torque wrenching or other methods commonly known in the art such that the clamps 144 secure the roof panels 108 to the frame 106. Thus, a flexibility in configuring the engine enclosure 104 by the adjustable positioning of the roof panels 108 on the frame 106 may save the operator effort required in aligning the openings 118, 120, and 122 with the auxiliary devices and set up the power system 100 quickly.
While aspects of the present disclosure have been particularly shown and described with reference to the embodiments above, it will be understood by those skilled in the art that various additional embodiments may be contemplated by the modification of the disclosed machine, systems and methods without departing from the spirit and scope of what is disclosed. Such embodiments should be understood to fall within the scope of the present disclosure as determined based upon the claims and any equivalents thereof.
