Solar array with service robot that can travel between solar panels
A travel path is arranged on the end faces of the solar panels and on which a service robot can travel, can rotate in place by a suitable rotational device, and can continue on a line. In this manner, the service robot can travel completely autonomously. For each row of adjacent solar panels, a centering opening is paired with the travel path, wherein the service robot has a centering pin which can engage into the centering opening, or the travel path is made of multiple sub-surfaces which form a respective rotary table in the region of the end faces of the solar panels, and the rotary table can be rotated about a perpendicular rotational axis running through the rotary table.
1 . A solar array comprising a plurality of solar panels that are set up in rows and can pivot about a pivot axle, as well as at least one service robot that can travel on the solar panels using drive elements,
wherein end faces of multiple solar panels are connected by way of a travel path that borders on the end faces, for travel of the service robot between multiple rows of solar panels, and means of rotation for rotating the service robot about a perpendicular rotational axis that runs within the service robot are provided,
wherein a centering opening located in a center of the travel path and in the rotational axis is assigned to the travel path for each row of adjacent solar panels, and
wherein the service robot has a centering pin arranged centrally in the service robot and in the rotational axis that can be moved into the centering opening and retracted from an underside of the travel path.
2 . The solar array according to claim 1 , wherein the travel path is formed from multiple sub-surfaces that form a rotary table in the region of the end faces of the solar panels, in each instance.
3 . The solar array according to claim 2 , wherein the rotary table can rotate about a perpendicular rotational axis that runs through the rotary table.
4 . The solar array according to claim 2 , wherein at least one travel table is arranged between two rotary tables.
5 . The solar array according to claim 1 , wherein the means of rotation comprise drive elements of the service robot that can be operated in opposite directions.
6 . The solar array according to claim 5 , wherein the drive elements of the service robot that can be operated in opposite directions are drive wheels, drive rollers or drive belts, which directly contact the surfaces of the solar panels.
7 . The solar array according to claim 1 , wherein the drive elements of the service robot are distributed over a length of the service robot that is both greater than the distance between two solar panels arranged in a row and also greater than the distance between the end face of a solar panel and the travel path.
8 . The solar array according to claim 1 , wherein the travel path is formed as a continuous travel table.
9 . The solar array according to claim 1 , wherein the service robot has side guide elements assigned to the service robot on both sides, for contacting longitudinal edges of the solar panels on both sides.
10 . The solar array according to claim 9 , wherein the side guide elements can be moved out of engagement with the longitudinal edges of the solar panels.
11 . The solar array according to claim 9 , wherein the side guide elements are four side guide rollers which are arranged so as to rotate around a perpendicular rotational axis and in such a manner that they are distributed uniformly around the service robot, and all have an identical distance from the centering pin, for introduction into the centering opening of a rotary table of the travel path.
12 . A solar array comprising a plurality of solar panels that are set up in rows and can pivot about a pivot axle, as well as at least one service robot ( 8 ) that can travel on the solar panels using drive elements,
wherein end faces of multiple solar panels are connected by way of a travel path that borders on the end faces, for travel of the service robot between multiple rows of solar panels, and means of rotation for rotating the service robot about a perpendicular rotational axis that runs within the service robot are provided,
wherein the travel path is formed by multiple sub-surfaces that form a rotary table in the region of the end faces of the solar panels, in each instance, and the rotary table can rotate about a perpendicular rotational axis that runs through the rotary table,
wherein a centering opening located in a center of the rotary table and in the rotational axis is assigned to the travel path for each row of adjacent solar panels, and
wherein the service robot has a centering pin arranged centrally in the service robot and in the rotational axis that can be moved into the centering opening and retracted from an underside of the rotary table.
13 . The solar array according to claim 12 , wherein at least one travel table is arranged between two rotary tables.
