Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution: a trash device for hydroelectric power generation comprises a flow channel 1, wherein three groups of symmetrically distributed slots 3 are formed in the inner wall surfaces of two sides of the flow channel 1, a mounting plate 2 is fixedly connected to the outer surface of one side of the flow channel 1, a rotating motor 8 is installed on the surface of the top of the mounting plate 2, a sliding groove 5 is formed in the surface of the side end of the mounting plate 2, a lead screw 7 is movably connected between the inner walls of two ends of the sliding groove 5, the output end of the rotating motor 8 is connected with the top end of the lead screw 7 through a speed reducer, a trash blocking mechanism 4 is arranged at the side end of the mounting plate 2, a mounting rod 9 is arranged on the trash blocking mechanism 4, a primary trash blocking plate 10, a secondary trash blocking plate 11 and a tertiary trash blocking plate 12 are sequentially connected to the bottom end of the mounting rod 9 from left to right, the primary trash blocking plate 10, the secondary trash blocking plate 11 and the tertiary, connecting block 13 side fixedly connected with horizontal pole 14, slider 15 is installed to the one end of horizontal pole 14, trash rack 4 passes through slider 15 and the 5 sliding connection of spout on the mounting panel 2, threaded hole 17 is seted up at 15 one end tops of slider, slider 15 passes through threaded

hole

17 and 7 threaded connection of lead screw.

Stopper 16 is all installed on 15 both sides surfaces of slider, spacing groove 6 has all been seted up on 5 both sides inner wall surfaces of spout, stopper 16 and 6 sliding connection in spacing groove improve 15 sliding stability of slider.

All be provided with mounting bracket 18 on one-level trash rack 10, second grade trash rack 11 and the tertiary trash rack 12, mounting groove 19 has been seted up to the 18 sides of mounting bracket, one-level trash rack 10, second grade trash rack 11 and tertiary trash rack 12 can be dismantled through mounting groove 19 above that and be connected with corresponding filter screen respectively, conveniently carry out the filter screen and change.
