The first drive assembly and the second drive assembly are disposed in the longitudinal portion, the cleaning roller and the water spray pipe are disposed opposite to the transverse portion, and the receiving cavity is used to receive the cleaning roller and the water spray pipe.

[0009] Furthermore, the first drive assembly includes a first drive member, a screw extending along the length direction of the longitudinal portion, and a connector that is drively connected to the screw; The connector is connected to the cleaning roller, and the drive unit is used to drive the screw to rotate in the forward / reverse direction, so that the connector drives the cleaning roller to reciprocate along the length of the screw.

[0010] Furthermore, the second drive assembly includes a second drive member, which is disposed on the connector, and the output end of the second drive member is connected to one end of the cleaning roller for driving the cleaning roller to rotate relative to the water spray pipe.

Detailed Implementation

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figures 1 to 5 The image shows a photovoltaic power generation module cleaning device according to one embodiment of the present invention. The photovoltaic power generation module 100 includes a photovoltaic bracket 110 for supporting multiple photovoltaic panels 120, and the multiple photovoltaic panels 120 constitute a cleaning area. It should be noted that in some actual situations, the photovoltaic power generation module 100 is not limited to the photovoltaic bracket 110 and photovoltaic panels 120 shown in this embodiment. It may also include other components. Since other components are conventional prior art in this field, they will not be specifically described here.

[0022] Specifically, the cleaning device includes a cleaning roller 200 facing the cleaning area, a water spray pipe 300 having a plurality of water spray nozzles 310, and a first drive assembly 400 for driving the cleaning roller 200 and the water spray pipe 300 to reciprocate along the cleaning area. The water spray pipe 300 is connected to the cleaning roller 200, and multiple water spray nozzles 310 are respectively positioned opposite different positions of the cleaning roller 200, so that the liquid medium output from each water spray nozzle 310 can be output to different positions of the cleaning roller 200, so that the cleaning roller 200 can clean each photovoltaic panel 120.

[0023] In practical implementation, multiple water nozzles 310 on the water spray pipe 300 are directed towards different parts of the cleaning roller 200, so that the liquid medium sprayed from the multiple water nozzles 310 can be output to different parts of the cleaning roller 200 respectively, so that all surfaces of the cleaning roller 200 can be coated with the liquid medium. Finally, the first drive component 400 drives the water spray pipe 300 and the cleaning roller 200 to move synchronously back and forth, so that the cleaning roller 200 can coat the surface of each photovoltaic panel 120 in the cleaning area with the liquid medium, and clean the surface of each photovoltaic panel 120 by using the reciprocating movement of the cleaning roller 200. This can solve the technical problems of low cleaning efficiency and long time consumption in the existing method of cleaning photovoltaic panels 120 by manually holding an electric mop.

[0024] In this example, the length of the water spray pipe 300 is the same as the length of the cleaning roller 200, and the length of the cleaning roller 200 is the same as the length of the cleaning area. It should be noted that the length of the cleaning area is the length of the multiple photovoltaic panels 120 together.

[0025] In some practical situations, to facilitate water supply to the water spray pipe 300, two transmission pipes can be installed on the water spray pipe 300. Please refer to [link / reference needed] for details. Figure 5 As shown, the liquid medium can be transferred to the water spray pipe 300 using the transfer pipe. It should be noted that the liquid medium can be pure water or a cleaning liquid with cleaning effect. Since the cleaning liquid is existing technology in this field, it will not be specifically described here.

[0026] To ensure cleaning effectiveness, in some preferred embodiments, the cleaning device further includes a second drive assembly 500 and a sleeve 600. The second drive assembly 500 is used to drive the cleaning roller 200 to rotate relative to the water spray pipe 300. The water spray pipe 300 is connected to the cleaning roller 200 through the sleeve 600. In other words, the second drive assembly 500 can drive the cleaning roller 200 to rotate, so that the cleaning roller 200 can effectively clean the impurities attached to the surface of the photovoltaic panel 120 in a rotatable manner. At the same time, the sleeve 600 can ensure the stability of the water spray pipe 300 during movement.

[0027] It should be noted that, in this example, the cleaning device also includes a mounting housing 700 for connection with the photovoltaic bracket 110. The mounting housing 700 includes a longitudinal portion 710 and a transverse portion 720 having a receiving cavity 730. The longitudinal portion 710 is arranged opposite to the longitudinal direction of the cleaning area, and the transverse portion 720 is arranged opposite to the transverse direction of the cleaning area. The first drive assembly 400 and the second drive assembly 500 are disposed in the longitudinal portion 710, the cleaning roller 200 and the water spray pipe 300 are arranged opposite to the transverse portion 720, and the receiving cavity 730 is used to receive the cleaning roller 200 and the water spray pipe 300.

[0028] In other words, by using the storage cavity 730, the cleaning roller 200 and the water spray pipe 300 can be stored in the storage cavity 730 in the initial state, so that when the cleaning roller 200 and the water spray pipe 300 are not used, external dust can be prevented from adhering to the cleaning roller 200 and affecting the cleaning effect on the photovoltaic panel 120.

[0029] Specifically, the first drive assembly 400 includes a first drive member 410, a screw 420 extending along the length direction of the longitudinal portion 710, and a connector 430 connected to the screw 420. The connector 430 is connected to the cleaning roller 200, and the drive member is used to drive the screw 420 to rotate in the forward / reverse direction, so that the connector 430 drives the cleaning roller 200 to reciprocate along the length direction of the screw 420.

[0030] The second drive assembly 500 includes a second drive member 510, which is disposed on the connector 430, and the output end of the second drive member 510 is connected to one end of the cleaning roller 200 for driving the cleaning roller 200 to rotate relative to the water spray pipe 300.

[0031] It should be noted that both the first driving component 410 and the second driving component 510 mentioned above can be servo motors as described in the art.

[0032] In addition, after the cleaning roller 200 finishes cleaning the photovoltaic panel 120, there will be a lot of impurities on the surface of the cleaning roller 200. In order to avoid affecting the cleaning effect of the photovoltaic panel 120 next time, in this example, the cleaning device also includes an intermittent cleaning component 800 disposed in the storage cavity 730. The intermittent cleaning component 800 is used to intermittently clean the cleaning roller 200 located in the storage cavity 730.

[0033] Specifically, the intermittent cleaning assembly 800 includes a rotating shaft 810 elastically rotatably connected within the receiving cavity 730, a cleaning plate 820 connected to the rotating shaft 810, and a first transmission member 830 sleeved on the rotating shaft 810. The first transmission member 830 has a first locking tooth 831. The second drive assembly 500 also includes a second transmission member 520 sleeved on the cleaning roller 200. The second transmission member 520 has a second locking tooth 521. The number of locking teeth of the second locking tooth 521 is less than the number of locking teeth of the first locking tooth 831. The first transmission member 830 and the second transmission member 520 are connected in a transmission manner. The cleaning plate 820 is used to face the cleaning roller 200.

[0034] It should be noted that the first transmission component 830 can be a gear with regular teeth, while the second transmission component 520 can be a gear with irregular teeth. That is, when the cleaning roller 200 and the water spray pipe 300 have moved into the receiving cavity 730 and completed their storage, the first drive component 410 can be stopped. At this time, the cleaning roller 200 and the water spray pipe 300 will remain stationary within the receiving cavity 730. By activating the second drive component 510, the cleaning roller 200 rotates within the receiving cavity 730. The rotation of the cleaning roller 200 causes it to move... The second transmission component 520 is rotated, and the meshing between the second transmission component 520 and the first transmission component 830 causes the rotating shaft 810 to drive the cleaning plate 820 to fold. Finally, the rotating shaft 810 is elastically rotatably connected in the storage cavity 730, so that when the cleaning plate 820 is folded, the elastic reverse force causes the cleaning plate 820 to pat the surface of the cleaning roller 200, thereby cleaning the impurities attached to the surface of the cleaning roller 200, thus ensuring the reliability of the cleaning roller 200 when cleaning the photovoltaic panel 120 in the next cycle.

[0035] It should be noted that a torsion spring can be used to elastically rotate the shaft 810 and the storage cavity 730.

[0036] In some preferred embodiments, to prevent sewage from entering the receiving cavity 730, in this example, the bottom of the horizontal portion 720 is provided with a hollow area 740, which faces the cleaning plate 820. The cleaning device also includes a guide plate 900, which is obliquely disposed at the bottom of the hollow area 740. The hollow area 740 and the guide plate 900 can be used to drain sewage from the receiving cavity 730. The guide plate 900 can also guide the sewage and prevent sewage from spilling onto the photovoltaic bracket 110.

[0037] In summary, the photovoltaic power generation module cleaning device according to one embodiment of this utility model has at least the following beneficial effects compared with existing methods for cleaning photovoltaic panels: In the photovoltaic power generation module cleaning device of this utility model, the arrangement of the cleaning roller 200, the water spray pipe 300 with multiple spray nozzles 310, and the first drive component 400 enables the cleaning of a cleaning area composed of multiple photovoltaic panels 120. The multiple spray nozzles 310 on the water spray pipe 300 are positioned directly on different parts of the cleaning roller 200, allowing the liquid medium sprayed from the multiple spray nozzles 310 to be output to different parts of the cleaning roller 200. This ensures that all surfaces of the cleaning roller 200 are covered with the liquid medium. Finally, the first drive component 400 drives the water spray pipe 300 and the cleaning roller 200 to reciprocate, allowing the cleaning roller 200 to coat the surface of each photovoltaic panel 120 in the cleaning area with the liquid medium. The reciprocating movement of the cleaning roller 200 cleans the surface of each photovoltaic panel 120, thus solving the technical problems of low cleaning efficiency and long time consumption associated with the existing method of cleaning photovoltaic panels 120 using a handheld electric mop.
