Abrégé

Provided are a walking drive mechanism of a photovoltaic array cleaning robot (20) and the photovoltaic array cleaning robot (20). The walking drive mechanism of the photovoltaic array cleaning robot (20) is configured to walk along an edge of a photovoltaic array (10) to drive the photovoltaic array cleaning robot (20) to move on the photovoltaic array (10). The walking drive mechanism comprises a top wheel assembly (2), a side wheel assembly (3), and a drive motor (4); a motion plane of the top wheel assembly (2) intersects with that of the side wheel assembly (3), wherein the walking drive mechanism further comprises a transmission assembly (5) configured to obtain power from the top wheel assembly (2) or the drive motor (4) and then change the transmission direction to drive the side wheel assembly (3) to move, so that the drive motor (4) can simultaneously drive the top wheel assembly (2) and the side wheel assembly (3) to move. The walking drive mechanism of the photovoltaic array cleaning robot and the photovoltaic array cleaning robot can enhance the obstacle-crossing ability of the photovoltaic array cleaning robot when dealing with jagged photovoltaic arrays.

Provided is a scraper mechanism of a photovoltaic panel cleaning apparatus, comprising a cross beam slidably provided on an upper rail and a lower rail, a scraper provided on the cross beam, a plurality of elastic compression assemblies that connect the scraper to the cross beam. Each elastic compression assembly comprises a fixed base provided on the cross beam, a plunger connected to the scraper, and an elastic hinge member provided in the fixed base and connected to the plunger. When the cross beam drives the scraper to slide along the length direction of the upper and lower rails, the elastic compression assemblies provided between the cross beam and the scraper compress the scraper onto the surfaces of photovoltaic panels. Compared with the prior art, when the cross beam drives the scraper to slide along the length direction of the upper and lower rails, the scraper can float up and down under the action of elastic force of the elastic compression assemblies according to the height drop between each two photovoltaic panels, so as to prevent the scraper from being jammed during cleaning.

Provided is a sweeping device for a photovoltaic panel, applied to a photovoltaic unit composed of a sequentially arranged plurality of photovoltaic panel arrays. The sweeping device for the photovoltaic panel comprises a guide rail mechanism formed by an upper rail and a lower rail respectively arranged at upper and lower sides of the photovoltaic panel arrays, and a plurality of scraper mechanisms for sweeping the photovoltaic unit. Each of the photovoltaic panel arrays at most corresponds to one scraper mechanism. The scraper mechanisms are slidably arranged on the guide rail mechanism corresponding to any photovoltaic panel array. The sweeping device further comprises: a cord mechanism for driving the scraper mechanisms to perform reciprocating motion on the photovoltaic unit, and a driving mechanism connected to the cord mechanism. Compared with the prior art, the driving mechanism can be used to drive the cord mechanism, and the scraper mechanisms perform reciprocating motion on the photovoltaic unit with the unwinding rope and winding rope of the cord mechanism so as to complete the sweeping of surfaces of the photovoltaic panel arrays. In contrast with the use of a robot, the sweeping device not only has a simple structure and is low cost, but also improves the sweeping efficiency of the whole photovoltaic unit.

Disclosed are a rail mechanism for a photovoltaic cell panel sweeping device, a trolley operation mechanism and a sweeping device. The trolley operation mechanism comprises a hauling rope (3), a guide rail (2) and a trolley (1). The trolley (1) is driven by the hauling rope (3) to move along the guide rail (2), wherein a hollow tube-shaped cavity (21) is formed in the interior of the guide rail (2), and at least part of the hauling rope (3) is inside the hollow tube-shaped cavity (21). A strip-shaped hole (23) is provided in the guide rail (2), so that the hollow tube-shaped cavity (21) is in communication with an external part of the guide rail (2) through the strip-shaped hole (23). A connection arm (11) is provided on the trolley (1), which connection arm (11) extends into the hollow tube-shaped cavity (21) through the strip-shaped hole (23) for connecting with the hauling rope (3). By using the trolley operation mechanism, the corrosion of the rope for hauling the trolley can be effectively avoided, thereby improving the dust-proof and water-proof capability of the sweeping device and thus extending the service life thereof.
