That is, by turning on the first electromagnet of each moving device 30 and 30', fixing the main body parts 310 and 310' to the first solar panel 10, and driving the first motor with the second electromagnet turned off. The movable supports 320 and 320' are moved to the right so that each of the movable supports 320 and 320' is raised above the upper frame 13 and the lower frame 13' of the second solar panel 12 .

In this way, the movable supports 320 and 320' move to the second solar panel 12 at the same time, as shown in FIG. 9(b), the frames 11 and 11' of the first solar panel 10 and the second solar panel When the panel 12 is in a state that spans both sides of the frames 13 and 13', it moves in the same manner as described with reference to FIGS. 7(c) and 7(d). That is, in a state in which the movable support parts 320 and 320 ′ are fixed to both sides of the frames 13 and 13 ′, the main body parts 310 and 310 ′ and the connecting plate 50 and the cleaning robot 20 seated thereon are the second solar panels 12 . ), and then each body part 310,310' is fixed to the second solar panel 12, and each movable support part 320,320' is moved further to the right so that the movable support part 320,320' is the second sun. Each of the upper frame 13 and the lower frame 13' of the light panel 12 is completely raised, thereby completing the movement between the panels of the solar panel cleaning device.

10 schematically shows a solar panel cleaning apparatus according to a third embodiment of the present invention. Referring to FIG. 10 , the cleaning device according to the third embodiment includes a cleaning robot 20 and a moving device 30 connected to each other by a wire 40 . The cleaning robot 20 and the moving device 30 of the third embodiment each have the same or similar configuration and operation as the cleaning robot 20 and the moving device 30 described with reference to FIGS. 1 to 6 , so a detailed description is given below. omit

However, in the third embodiment, the moving device 30 further includes a rotating frame 70 hinged by a hinge 71 . The rotation frame 70 is hinge-coupled to the main body 310 of the moving device 30 to be rotatably attached, and at least a penetration region 70a having a larger area than the cross-section of the cleaning robot 20 is formed. Although not shown in the drawings, the rotating frame 70 may be rotated around the hinge 71 by a driving means such as a motor provided in the main body 310 .

11 is a view for explaining a movement operation between the solar panels of the solar panel cleaning apparatus according to the third embodiment of FIG.

As shown in Fig. 11 (a), two solar panels 10 and 12 are arranged adjacent to each other, and the cleaning device of the present invention (that is, the cleaning robot 20 and the moving device 30) is located on the left side. It is assumed that the first solar panel 10 moves to the right second solar panel 12 .

First, as a preparation step for movement between the solar panels, the cleaning robot 20 should be mounted on the rotating frame 70 . To this end, in a state in which the main body 310 is moved to a predetermined position on the upper right side of the first solar panel 10 , the cleaning robot 20 closely adheres to the main body 310 and is positioned at a predetermined position. After that, the rotation frame 70 rotates toward the cleaning robot 20 . At this time, the through region 70a of the rotation frame 70 of the cleaning robot 20 is located at a position through which the cleaning robot 20 rotates the rotation frame 70 as shown in FIG. 11(a). It does not interfere with the rotation frame 70 can be rotated until it reaches the surface of the first solar panel (10).

After that, the cleaning robot 20 moves over the rotation frame 70 and is seated. That is, as shown in FIG. 11( b ), the cleaning robot 20 may move slightly downward to rise above the rotation frame 70 to be seated.

The subsequent operation operates in the same manner as in Figs. 7(b) to 7(d). That is, in a state in which the main body 310 is fixed to the first solar panel 10 , the movable support 320 moves toward the second solar panel 12 , and the upper frame ( 11) and the second solar panel 12 is fixed across both sides of the upper frame 13 (see FIG. 7(b)), and in this state, the movable support 320 is fixed to the solar panels 10 and 12 and the main body 310 and the rotating frame 70 and the cleaning robot 20 seated thereon move to the second solar panel 12 along the movable support 320 (see Fig. 7(c)). Then the main body 310 is fixed to the second solar panel 12 and the movable support 320 is moved further to the right so that the movable support 320 is above the upper frame 13 of the second solar panel 12 . It goes up completely and the movement between the panels of the solar panel cleaning device is completed (see Fig. 7(d)).

As described above, those of ordinary skill in the art to which the present invention pertains can understand that various modifications and variations are possible from the description of this specification. Therefore, the scope of the present invention should not be limited to the described embodiments and should be defined by the claims described below as well as the claims and equivalents.
