Disclosed is an automatic cleaning and maintaining device powered up through solar energy and used for a bridge. The bridge comprises a horizontal main girder (4) and auxiliary girders (41). The horizontal main girder (4) is provided with a guide rib (2) extending horizontally, and the auxiliary girders (41) are supported on the horizontal main girder (4). The automatic cleaning and maintaining device comprises a supporting frame (99), a water supply tube (61) and a nozzle (62). The water supply tube (61) is supported on the supporting frame (99) and close to the main girder (4), and the nozzle (62) is communicated with the water supply tube (61) so as to be aligned with the position to be cleaned of the bridge for water spraying cleaning. Multiple guide protrusions extending along the guide rib (2) are arranged on the upper surface and the lower surface of the guide rib (2) respectively.

The invention discloses a speed-adjustable cleaning and maintaining device provided with a flickering indicator lamp and used for an outdoor steel member. The cleaning and maintaining device is used for cleaning and maintaining the outdoor steel member. The outdoor steel member comprises a main beam (4) and secondary beams (41) supported on the main beam (4), wherein the main beam (4) is provided with a guide rib (2) extending in the longitudinal direction. The cleaning and maintaining device comprises a support frame (99), a water supply pipe (61) which is supported on the support frame (99) and close to the main beam (4), and a nozzle (62) communicated with the water supply pipe (61). A plurality of guide protrusions extending in the longitudinal direction are arranged on each of the upper surface and the lower surface of the guide rib (2) and can be matched with peripheral grooves (920) in an upper supporting idler wheel (921) and peripheral grooves (910) in a lower supporting idler wheel (911) of the cleaning and maintaining device, wherein the upper supporting idler wheel (921) is connected to the upper surface of the guide rib and the lower supporting idler wheel (911) is connected to the lower surface of the guide rib.

Disclosed is an automatic clearing and maintaining device which uses a ventilation fan for heat dissipation and is used for a bridge. The bridge comprises a transverse main girder (4) provided with a guide rib (2) extending transversely, and auxiliary girders (41) supported on the transverse main girder (4). The automatic clearing and maintaining device comprises a support frame (99), a water supply pipe (61) supported on the support frame (99) and close to the main girder (4), and a nozzle (62) which is communicated with the water supply pipe (61) to be aligned with the part, needing to be cleared, of the bridge to spray water for clearing. The upper surface and the lower surface of the guide rib (2) are provided with a plurality of guide protrusions extending along the guide rib (2) respectively.

Disclosed is an automatic cleaning and maintaining device with the good damping effect for a bridge. The bridge comprises a main transverse beam (4) and an auxiliary beam (41), wherein the main transverse beam (4) is provided with a guiding rib (2) transversely extending, and the auxiliary beam (41) is supported on the main transverse beam (4). The automatic cleaning and maintaining device comprises a supporting frame, a water supply pipe (61) and a nozzle (62), wherein the water supply pipe (61) is supported on the supporting frame and is close to the main transverse beam (4), and the nozzle (62) is communicated with the water supply pipe (61) so as to be aligned to the portion, needing to be cleaned, of the bridge to spray water and clean the portion. The upper and lower surfaces of the guiding rib (2) are each provided with a plurality of guiding protrusions extending along the guiding rib (2).

The invention provides an improved automatic bridge cleaning and maintenance device. A bridge includes a horizontal girder (4) with a horizontally extending guiding rib (2), and a secondary girder (41) supporting the horizontal girder (4); the automatic cleaning and maintenance device includes a support frame (99), a water supply pipe (61) supported by the support frame (99) and near to the horizontal girder (4), and a nozzle (62) communicated with the water supply pipe (61) and aligned to the part required to be cleaned of the bridge, so as to clean the part by spraying water; a plurality of guiding bulges extending along the guiding rib (2) are arranged on the upper surface and the lower surface of the guiding rib (2) respectively.

The invention discloses an automatic cleaning maintaining device provided with guide rods and used for a bridge. The bridge comprises a transverse main beam (4) provided with a transversely-extending guide rib (2) and auxiliary beams (41) supported on the transverse main beam (4). The automatic cleaning maintaining device comprises a supporting frame (99), a water supplying pipe (61) which is supported on the supporting frame (99) and close to the main beam (4) and a nozzle (62) communicated with the water supplying pipe (61) so that the automatic cleaning maintaining device can be aligned with the portion, needing to be cleaned, of the bridge for water spraying cleaning.
