     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates generally to mobile containers for housing power generation machinery or stations, and more particularly, to semi-tractor trailer containers incorporating improvements for housing and accommodating power generation machinery. 
         [0004]    2. Description of Related Art 
         [0005]    Mobile power generation systems capable of delivering megawatts of power are known to offer certain advantages compared to power delivered from an electrical utility power distribution grid. Mobile power generation systems can provide power as needed at times of peak demand or during brownout in a distribution grid, or during an emergency caused by a failure in the distribution grid. A mobile power generation system can be located at places distant from a distribution network where there is need for power, thus minimizing any delay or the need or expense for constructing power lines to distant or remote places. 
         [0006]    The conventional method of transporting a mobile power station is to mount an industrial electric generator to the floor within a trailer or a stackable shipping container which is placed on a semi tractor trailer. Power generators are conventionally secured to the floor of a shipping container or semi trailer by aligning mounting holes of the generator to corresponding mounting apertures on the floor of the shipping container or semi trailer. Given the size and weight of industrial generating equipment, it can be very difficult to align mounting holes of the generating equipment with the mounting apertures in the floor. Furthermore, the mounting holes of generating equipment do not always align perfectly with the mounting apertures on the trailer floor, thus further complicating the mounting process. Additionally, the substantial weight of industrial equipment requires the floors mounting such equipment to be structurally reinforced to support such weight. Industrial generating equipment also can have some spillage of oil, fuel, coolant, and other fluids. When these fluids escape from the generating equipment, the fluids simply spill onto the floor, creating dangerous conditions for operators and maintenance personnel. U.S. Pat. No. 9,051,011, which is hereby incorporated by reference, discloses improvements for mounting industrial equipment to the floors of shipping containers or semi-tractor trailers. 
         [0007]    In addition to the need for improved floor mounting systems in such power generation containers, there also are needed improvements in facilitating access to the power generating machinery inside the containers, container exhaust systems, and mounting fixtures on the containers. 
       ASPECTS AND SUMMARY OF THE PRESENT INVENTION 
       [0008]    One aspect of the present invention is to facilitate and provide greater access to power generation machinery inside power generation containers. 
         [0009]    Another aspect of the present invention is to provide improved mounting fixtures for power generation containers that can be more easily painted, cleaned, and modified. 
         [0010]    A further aspect of the present invention is to provide improved exhaust and ventilation systems for power generation containers. 
         [0011]    An additional aspect of the present invention is to provide easy access ladders for maintenance on the roof of power generation containers. 
         [0012]    In order to achieve the above aspects and more, the present invention provides an improved power generation container providing improved access and installation and removable of internal machinery by using modular components. A self bailing and self-aligning exhaust system is further provided.

       [0054]    The foregoing has outlined, rather broadly, the preferred features of the present invention so that those skilled in the art may better understand the detailed description of the invention that follows. Additional features of the invention will be described hereinafter that form the subject of the claims of the invention. Those skilled in the art should appreciate that they can readily use the disclosed invention and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention, and that such other structures do not depart from the spirit and scope of the invention in its broadest form. 
       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0055]    Referring now to the drawings,  FIG. 1  illustrates a door frame  10  for a self-bailing door assembly to be located on the side of a power generation container, such as a semi-tractor trailer. Self bailing refers to the ability to directly receive or accumulate rain water without it entering the power generation container. The self-bailing achieved by specific gravity, all components fit from under another component with the bottom being sealed and self-draining the exterior. The frame  10  includes an outer rim or outer panel  12  that preferably are weld together at the corners  13  to form a rectangular configuration. The frame  10  houses and mounts the dual door assembler  14  shown in  FIG. 2 . A removable center post  16  shown in  FIG. 1 c    is secured within the frame  10  by fitting one end of the post  16  within a slot  18  in the top of the frame  10 , and the other end of the post  16  in a notch  20  in the base or bottom of the frame  10 . The frame  10  preferably is constructed of a metal, such as steel. 
         [0056]      FIG. 1 a    illustrates an estop receptacle  22  mounted to the outer rim  12  of the frame  10 . The estop receptacle  22  houses components for an emergency stop button for a power generation system to be contained within the power generation container. 
         [0057]      FIG. 1 b    illustrates a flat blank plate  24  for covering an unused port or aperture for mounting an estop receptacle  22 . The blank plate  24  preferably is constructed of metal and can be easily removed or replaced for adding or removing an estop receptacle  22 . 
         [0058]    In accordance with the present invention, the estop receptacle  22  can be easily added or removed from estop ports or apertures  37 . Moreover, the estop receptacle  22  can be pre-wired and installed on any outer surface of a container by simply making an aperture in the container for the wiring to pass through, and the bolting or welding the estop receptacle to the outer surface of the container. This feature of the present invention enables estop receptacles to be easily added to desired upper locations when a container is on the ground, or located in a lower location when a container is located at a higher location, such as when on a semi-trailer, or at multiple estops at multiple locations. A blank plate  24  can easily cover an unused estop port  21 . By enabling estop receptacles  22  to be easily removed and repositioned to a preferred located, this reduces the cost of having to provide multiple estop receptacles  22  for various potential locations. 
         [0059]    Additionally, enabling the estop receptacle to be added or removed allows the estop receptacle to be easily painted and cleaned, thus preventing rust and dirt built up. The numeral intricate structures and fixtures located within the estop receptacle make it very difficult to paint and clean when mounted, this leading to rust and corrosion. By enabling the estop receptacle  22  to be painted completely before being mounted by submerging in it in paint, enables the estop receptacle to be completely covered by paint and thoroughly protected from rust and corrosion. Moreover, the estop receptacle  22  can be removed for easy cleaning or repainted if needed. It the estop receptacle was welded to the container wall, as is conventionally, done such thorough cleaning or painting would not be possible.
