The invention relates to a method for creating a sealed joint (118) between elongate parts (14, 116) of an aircraft extending locally in main directions that are not mutually parallel; a plurality of parts of a mould are assembled on the parts; and a sealing material is injected into the mould.

The invention provides a sun-tracking photovoltaic power generation device, and relates to solar power generation equipment. The device comprises a support, a crossed turning mechanism, a main swing mechanism, a pitch swing mechanism and a rectangular tray bearing a solar power generation device array, wherein the crossed turning mechanism is fixed at the upper end of the support and can be connected with the center point of the tray in a biaxially swinging manner; the main swing mechanism winds or unwinds eastern and western steel cables through a main winch, the steel cables are connected with the middles of the eastern and western edges of the tray, so that the tray can swing eastwards and westwards, a main heavy punch and a main upper pulley are arranged at the upper end of the western steel cable or the eastern steel cable, and the main heavy punch is used for balancing the length difference of upward extension parts of the western and eastern steel cables when the tray swings eastward and westward; the pitch swing mechanism winds or unwinds southern and northern steel cables through an auxiliary winch, the southern and northern steel cables are connected with the middles of the southern and northern edges of the tray, then the tray can perform pitch swinging, an auxiliary heavy punch and an auxiliary upper pulley are arranged at the upper end of the southern or northern steel cable, and the auxiliary heavy punch is used for balancing the length difference of upward extension parts of the southern and northern steel cables when the tray performs pitch swinging. The anti-wind capacity can be improved.
