Equivalent storage container for hydrogen gas concentration test of lead storage battery mounted on explosion-proof vehicle

摘要

PURPOSE:To make a test with high accuracy by taking out a storage battery to be mounted to a vehicle and housing the battery into an equiv. housing vessel. CONSTITUTION:The equiv. housing vessel 5 is provided with a housing vessel body 6, a cap plate 52 which closes the top aperture surface of the body 6 and has a gaseous hydrogen escaping part 51 and a door 63 for putting in and out of a storage battery box 33 at one end. The body 6 is formed of a material such as the same metallic material used for the body of the storage battery housing chamber which does not absorb hydrogen to the top-opened and bottomed box shape having the same size and shape as the size and shape of the housing chamber fixed to the vehicle. Said body is formed with one or plural rectangular holes at one end in the same position as the cap plate of the fixed housing chamber for inspection of the box 33 and is integrally projected with a rising wall 54 and a top plate 55. Slit holes 56 communicating with the rectangular holes are provided to the wall 54 to constitute the gaseous hydrogen escaping part 51. The storage battery is independently and accurately tested simply by taking out the box 33 and housing the same into a container 5.
