For realizing above-mentioned technical purpose, the present invention adopts following scheme: a kind of power shovel unexplosive current collector, comprise a casing, the left side of casing is installing plate, casing outside top is provided with junction box, it is characterized in that: junction box bottom is provided with junction pole, and junction pole is around seal area, seal area upper end is movable pressing board, and inside, seal area is all fluid sealant; Junction box and casing binding site are added with fluid sealant, a power transmission shaft is extended in casing left side, a shifting disc is installed at power transmission shaft top, and power transmission shaft and casing left side and the position contacting with installing plate are provided with bearing group, and installing plate and bearing group binding site are all added with fluid sealant; Power transmission shaft is inner through a cable inner core, and in cable, core inner is cable; Box house, collector ring component is enclosed within on power transmission shaft, and collector ring prap is installed on collector ring component; Insulation blanket stud is fixed in casing inner left wall, and brush is installed on insulation blanket stud, and two projections in brush outside are brush joint, and brush and collector ring component are slidably connected; Cable in cable inner core is connected with collector ring prap, and brush joint can be connected with junction box by wire.
Described cable inner core and power transmission shaft close-fitting, cable inner core runs through power transmission shaft and collector ring component, and cable inner core is added with fluid sealant in the leftmost side contacting with collector ring component.
In described cable, the cable of core inner is divided into two groups of thicknesses, and every group is respectively three.
Described fluid sealant is all organosilicon sealant.
Beneficial effect of the present invention is: the present invention by bearing group, collector ring component and cable inner core close-fitting extremely together, compressed its spatial area, reduced volume, reduced cost and more easily installed, the seal area at the leftmost side that cable inner core contacts with collector ring component, installing plate and bearing group binding site, junction box and casing binding site and junction box back panel wiring bar place is all added with fluid sealant, guaranteed the sealing of box house and junction box inside, effectively prevent that electric spark from overflowing, make the use of power shovel safer; In cable, the cable of in-core divides two kinds, and the power shovel that is applicable to different model uses.
