Please refer to FIG. 3 and FIG. 4 together. The relationship between the cleaning device 20, the linear guide 30 and the curved guide 40 on the solar panel 200 is disclosed in the two embodiments.

In the third embodiment, the cleaning device 20 is disposed in the middle of the linear guide 30 and the curved guide 40. The solar panel 200 is disposed on the same plane as the curved guide 40, and the first joint portion 21 and the second joint portion 22 are disposed in the cleaning portion. The opposite sides of the 23 are respectively coupled to the linear guide 30 and the curved rail 40. The linear guide 30 and the first joint portion 21 can be configured as a rack and a gear, and the curved guide 40 and the second joint 22 can be combined with each other. Similarly, Fig. 4 is a guide groove having a curved path and a rod guide member corresponding to the path width of the guide groove.

In the fourth embodiment, the linear guide rail 30 and the curved guide rail 40 are disposed on different planes on the same side. In the embodiment, the curved guide rail 40 is disposed above the linear guide rail 30, and the curved guide rail 40 is a hollow guide groove and a linear guide rail. 30 is a bottom surface, and the first joint portion 21 and the second joint portion 22 are on two different planes of a rod body. Above the rod body, the cleaning portion 23 is supported to be located on the light-facing side of the solar panel 200, and the rod body passes through the crucible. The first guiding portion 21 is located at the hollow guiding groove, and the curved path of the hollow guiding groove can restrict the lateral reciprocating displacement of the rod body, and the bottom portion of the bottom portion of the rod body is the first joint portion 21 to maintain the cleaning portion 23 at On the same level, the cleaning portion 23 can also produce a longitudinal linear displacement by gravity.

In such an arrangement, only the cleaning device 20 can be disposed on the light-facing side of the solar panel 200, and the linear guide 30 and the curved guide 40 can be disposed on the backlight side of the solar panel 200, thereby reducing objects located on the light-emitting side of the solar panel 200. The light receiving area of the solar panel 200 is increased.

Referring to FIGS. 1 and 5 together, in this embodiment, it is disclosed that the stop or slide of the cleaning device 20 is simply controlled from the configuration of the structure.

This embodiment is further modified according to the structure shown in FIG. 4. As shown in the figure, the linear guide rail 30 on the lower side may include a slip-stop structure 31, which may be a dot-shaped groove, when the first joint portion 21 slides. Up to the anti-slip structure 31, and the solar panel 200 and the frame 210 assume a first angle θ1, the weight w of the cleaning device 20 produces a component force parallel to the linear guide 30, and stops in the anti-slip structure 31. When the solar panel 200 is tilted to the second angle θ2 by the rotation control device 12, the weight w of the cleaning device 20 generates a horizontal component force F1 that overcomes the maximum component force generated by the vertical component force F2 and the anti-slip structure 31. The cleaning device 20 can be detached from the other end of the linear guide 30 by the detachment of the anti-slip structure 31.

The second angle θ2 may be greater than a maximum angle generated when the solar panel 200 performs day tracking, whereby the anti-slip structure 31 may limit the cleaning device 20 from slipping during the day, and the solar panel 200 may be controlled by the rotation control device 12 at night. The two angles θ2 are used to slide the cleaning device 20 and clean the light-facing surface of the solar panel 200, but the implementation is not limited thereto. For example, the center of gravity configuration of the cleaning device 20 can also be adjusted such that the horizontal component force F1 produced at the second angle θ2 can overcome the maximum frictional force generated by the anti-slip structure 31.

In practice, the above arrangement may also be a track for disposing the anti-slip device 60 as shown in FIG. 6 in the cleaning device 20, and the anti-slip device 60 may be electrically connected to the rotation control device 12 to be rotated according to the rotation control device 12. The time period information 120 above selectively stops or moves the cleaning device 20. For example, the anti-slip device 60 can be set to limit the cleaning device 20 to be located on one side of the solar panel 200. The side edge will rise to the highest point at night and then the restriction of the anti-slip device 60 is released, so that the cleaning device 20 is gravity-dependent. It is dropped to further clean the glossy surface of the solar panel 200.

Referring to FIGS. 1 and 6 together, this embodiment discloses how the swinging gravity cleaning system 100 of the present invention can be adjusted during rainy days to achieve additional cleaning of the solar panel 200.

In FIG. 6 , the swing type gravity cleaning system 100 further includes a slip preventing device 60 and a humidity sensor 70. The anti-slip device 60 is disposed on the track on which the cleaning device 20 is displaced and is electrically connected to the rotation control device 12, and the humidity is sensed. The detector 70 is electrically connected to the rotation control device 12 and obtains the rain information 701 on a rainy day. When the rotation control device 12 receives the rain information 701, it first controls the anti-slip device 60 to limit the position of the cleaning device 20 and places it on one side of the solar panel 200, and then the rotation control device 12 controls the solar panel 200 to rotate to the first The three angles θ3 cause the side of the solar panel 200 where the cleaning device 20 is located to be the height of the solar panel 200 (the left side of the solar panel 200). Since the solar panel 200 is inclined, it is also advantageous for discharging the water accumulated on the solar panel 200.

When the rain stops, the anti-slip device 60 on the running track of the cleaning device 20 is removed, so that the cleaning device 20 is moved by gravity to the lower portion of the solar panel 200 (the right side of the solar panel 200), and the remaining water remaining on the solar panel 200 is removed. If the sun is biased toward the left side of the solar panel 200 and the tracking sensor 50 is restarted, the rotation control device 12 is rotated to the fourth angle θ4 to direct the solar panel 200 toward the sunlight.

In practice, the rocking gravity cleaning system 100 can be electrically connected or wirelessly connected to the weather system 300 and based on the weather information 310 generated by the weather system 300 to control the frequency at which the cleaning device 20 performs cleaning. For example, when the weather information 310 indicates that there is a dust storm in recent days, the cleaning device 20 can be controlled to perform multiple cleanings at night to remove more dust. When the weather information 310 indicates that the rainy season is coming, the failure is due to failure. More solar energy is received, and the rain can also sufficiently remove the dust, thereby reducing the number of times the cleaning device 20 is cleaned, but the implementation is not limited thereto.

For example, in order to control the movement of the cleaning device 20, in addition to its own gravity, an actuation device (not shown) may be added to control the movement of the cleaning device 20, and the cleaning device 20 is controlled by the actuation device for cleaning. Frequency to adapt to weather or climate changes.

Please refer to FIG. 1 and FIG. 7 together. This embodiment discloses how to apply the rocking gravity cleaning system 100 to the solar-panel solar panel 200 disposed on the exterior wall of the building, in order to make the cleaning device 20 suffer from its own The weight w is lowered, and the linear guide 30 and the curved guide 40 are disposed on both sides of the solar panel 200 and perpendicular to the surface, and the cleaning device 20 is disposed on the light side of the solar panel 200 so that it can slide up and down, and The movable device 80 is connected to one end of the cleaning device 20, and is fixed to the high position of the solar panel 200 when the cleaning device 20 is used for cleaning. When the predetermined cleaning time is reached, the cleaning device 20 is not fixed, so that it is freely dropped according to gravity. The light side of the solar panel 200 is cleaned, and the actuating device 80 is used to provide an upward force F3 for the solar panel 200 to return the cleaning device 20 to the upper portion of the solar panel 200.

In practice, it is possible to set the cleaning device 20 to fall freely at night, clean the solar panel 200, and when the peak time for generating electricity by the solar panel 200 is about to end, use the electric power to pull the cleaning device 20 back to the height of the solar panel 200. To make full use of the electrical energy generated by the solar panel 200.

In practice, the above-mentioned actuating device 80 may also be disposed on the sun-filled solar panel 200 installed on the ceiling to control the cleaning device 20 to be further cleaned on the solar panel 200, but the implementation is not limited thereto. .
