The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
See among Fig. 1, Fig. 2 and Fig. 3: the present invention includes metal cabinet 1, its four walls and bottom surface adopt metal sheet to be welded, metal cabinet 1 interior arrangement battery pack 7, metal cabinet 1 lateral means watertight socket 8, metal cabinet 1 bottom device priming valve 9, oil-filled or the oil in the storage battery box emitted in the storage battery box by priming valve 9.The port bolt together device of metal cabinet 1 " returns " flange of font, and the edges cover of compensation leather bag 2 is connected on the flange, and the bolt together device " returns " cover plate 3 of font on the compensation leather bag 2, and its size is corresponding with the flange of " returning " font.For protecting soft compensation leather bag 2 not scratched by foreign matter; bolt together is fixed with protective cover above cover plate 3; it is made of low protection cover 4 and last protective cover 5 bolt togethers; low protection cover 4 reaches to go up between the protective cover 5 dividing plate; perforate is arranged on the dividing plate, and described low protection cover reaches on the cover wall of going up protective cover perforate.The compensation leather bag can stretch in the flange of " returning " font and the space between the low protection cover 4, plays compensating action.The compensation leather bag is a gauffer formula oil-proof rubber leather bag, according to the requirement decision compensation leather bag gauffer amount design of compensation oil mass.Check valve 6 is equipped with on compensation leather bag top, and check valve 6 passes low protection cover 4 and goes up the perforate on the dividing plate between the protective cover 5.Perforate on low protection cover 4 and the last protective cover 5 is for ventilative and expendable weight, and the height of last protective cover 5 is by the requirement decision of compensation oil mass.In order to gain in strength, be welded with reinforced rib on casing 1 wall.
