The implementations described in the following example embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0040] In the present disclosure, the orientation words such as "inner" and "outer" are defined according to the contour of the corresponding parts themselves unless otherwise stated. The terms such as "first", "second" and the like used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance.
[0041] Embodiment 1
[0042] Basically as shown in the accompanying Figure 1 to the accompanying Figure 2 As shown, a photovoltaic cleaning assembly is used to clean the photovoltaic panel, and can also avoid impurities falling onto the surface of the photovoltaic panel.
[0043] The photovoltaic cleaning assembly of the present embodiment includes a cleaning module 1 and a dispersing module 2. The impurities on the photovoltaic panel are removed by the cleaning module 1, and the impurities are lifted. The impurities on the photovoltaic panel can be dust, leaves, and bird droppings, etc. When the impurities are lifted, the lifted impurities are dispersed by the dispersing module 2, so as to avoid the impurities from falling onto the surface of the photovoltaic panel again, and improve the cleaning effect of the photovoltaic panel.
[0044] In the present embodiment, the cleaning module 1 is preferably a roller brush module, as shown in the accompanying Figure 1 The roller brush module includes a roller brush 11 and a driving unit 12. The roller brush 11 is in the form of a long strip, and is preferably a nylon roller brush 11. The roller brush 11 is installed on a rack through a rotating shaft, and the rack is in the form of a U-shaped. The roller brush 11 can rotate on the rack. The driving unit 12 is a driving motor, which is fixedly installed on the rack through a fastener. The output shaft of the driving motor is provided with an output gear, and the connecting shaft of the roller brush 11 is provided with a transmission gear. The output gear and the transmission gear are in meshing transmission state. In the present embodiment, both the output gear and the transmission gear are preferably conical gears. In the present embodiment, the driving unit 12 is provided in two, and the two driving units 12 are respectively arranged on both sides of the rack, and the two driving units 12 are in transmission connection with both ends of the roller brush 11. The two driving units 12 cooperatively drive the roller brush 11 to rotate.
[0045] For example, when the driving motor is working, the driving motor drives the rolling brush 11 to rotate through the gear transmission. When the rolling brush 11 rotates, the rolling brush 11 cleans the impurities on the photovoltaic panel, and the impurities are lifted by the rolling brush 11.
[0046] It should be noted that in this embodiment, the transmission is achieved through gear engagement, but in some other embodiments, there are various ways for the driving motor to drive the rolling brush 11 to rotate. For example, the driving rotation of the rolling brush 11 can be achieved through belt transmission, chain transmission, or direct connection of the output shaft of the driving motor to the rolling brush 11.
[0047] It should be noted that in this embodiment, the cleaning module 1 is provided as a rolling brush 11, and the impurities are separated from the photovoltaic panel through the rotation of the rolling brush 11. However, in some other embodiments, the cleaning module 1 can also be other modules in the prior art, for example, in some embodiments, the cleaning module 1 can be provided as a brush disc module, which includes a brush disc and a driving unit 12. The brush disc can be provided as one or more. The driving unit 12 is a driving motor, which corresponds to the brush disc one-to-one. The output shaft of the driving motor is directly connected to the brush disc. When the driving motor works, the driving motor drives the brush disc to rotate, and the brush disc separates the impurities from the photovoltaic panel and also lifts the impurities.
[0048] As shown in Figure 2 The dispersion module 2 of this embodiment includes a gas supply unit 21 and a release component 22. The release component 22 is installed on the rack, and the front end of the release component 22 is provided with an air outlet in the form of a straight line. The air outlet of the release component 22 is obliquely arranged above the rolling brush 11. The release component 22 is internally constructed with an air duct, and the inlet of the air duct is an air inlet. The air inlet is provided with a gas supply unit 21 through the configuration of a fastener, which can be a blower or a compressed gas cylinder.
[0049] For example, when the rolling brush 11 rotates, the rolling brush 11 lifts the impurities on the photovoltaic panel, and then the gas supply unit 21 delivers the airflow into the release component 22. The airflow flows along the inside of the release component 22, and finally the airflow is released from the air outlet at the front end of the release component 22. The airflow disperses the impurities lifted by the rolling brush 11 to the front end, avoiding the impurities from falling on the photovoltaic panel that has been cleaned.
[0050] Embodiment 2
[0051] The difference between this embodiment and embodiment 1 is that Figure 3As shown, in this embodiment, the preferred dispersing module 2 is a fan, which is directly installed on the frame. Multiple fans are provided, and the air outlet of the fan faces the roller brush 11.
[0052] To illustrate with an example application scenario: When the roller brush 11 rotates, it lifts up the impurities on the photovoltaic panel. Then, the fan operates and blows air towards one side of the roller brush 11, dispersing the impurities lifted up by the roller brush 11 and preventing them from falling onto the newly cleaned photovoltaic panel.
[0053] Example 3
[0054] The difference between this embodiment and Embodiment 1 or Embodiment 2 is that, as Figure 4 As shown, when the roller brush 11 cleans the entire photovoltaic panel using an N-shaped or Z-shaped route, the two ends of the photovoltaic cleaning module are divided into cleaned and uncleaned areas. At this time, when the dispersing module 2 disperses impurities, these impurities can easily fall onto the cleaned photovoltaic panel, thus contaminating the cleaned panel.
[0055] To address the aforementioned issues, this embodiment preferably includes at least two release components 22, and more preferably two. Each release component 22 is a nozzle, with both nozzles mounted on the frame, facing either the left front or right front side of the roller brush 11. The two release components 22 are connected to a gas supply unit 21 via pipes. The gas supply unit 21 can be a blower. Additionally, this embodiment's dispersing module 2 also includes an adjustment unit, preferably a three-way valve. The gas supply unit 21 and the release components 22 are connected via the three-way valve. The three-way valve can adjust the connection state between the gas supply unit 21 and the release components 22.
[0056] Taking one application scenario as an example: when the roller brush 11 cleans the photovoltaic panel in different directions, the gas supply unit 21 is connected to different release components 22 by adjusting the three-way valve, so that the airflow blows the impurities in different directions, preventing the impurities from falling onto the photovoltaic panel that has been cleaned.
[0057] It should be noted that, in this embodiment, two release components 22 are preferably provided. However, in some other embodiments, three, four, or five release components 22 may also be provided. The air outlets of different release components 22 face different directions. Of course, in order to ensure the supply of airflow, the number of gas supply units 21 can be appropriately increased according to the number of release components 22.
[0058] It should be noted that, in this embodiment, the two release components 22 are preferably positioned facing the left front side and the right front side; however, in some other embodiments, such as... Figure 5As shown, two release components 22 can also be provided at the ends of the roller brush 11, with the two release components 22 facing the left and right sides respectively.
[0059] Example 4
[0060] This embodiment provides a photovoltaic cleaning robot, such as Figure 6 As shown, the photovoltaic cleaning components and mobile modules include those of Embodiment 1, Embodiment 2, or Embodiment 3.
[0061] In this embodiment, the mobile module is preferably a mobile vehicle 3, such as... Figure 7 As shown, the mobile vehicle 3 can move on the surface of the photovoltaic panel. In this embodiment, the mobile vehicle 3 includes a frame 31 and a drive module 32. The frame 31 is rectangular, and its front end is fixedly connected to the frame in the photovoltaic cleaning assembly. In practice, this connection can be achieved using fasteners. Drive modules 32 are configured on both the left and right sides of the frame 31. Each drive module 32 is a synchronous pulley module, which powers the frame 31 to move.
[0062] In this embodiment, the frame 31 also includes an adsorption module 33. The adsorption module 33 is used to adsorb the photovoltaic panels, making the photovoltaic cleaning robot more stable when moving on the photovoltaic panels. Multiple adsorption modules 33 can be provided in this embodiment, such as two, three, or four. The adsorption module 33 can be the adsorption module 33 of the prior art. The adsorption modules 33 are mounted on the frame 31 and arranged in a straight line.
[0063] Example 5
[0064] This embodiment is an improvement on embodiment 4, such as... Figure 8 As shown. To meet the requirements for use across gaps and ensure greater stability of the frame 31 when crossing gaps, in this embodiment, the frame 31 includes at least three connecting sections: a front section 31a, a middle section 31b, and a rear section 31c, arranged in a straight line. The front section 31a and the middle section 31b are movably connected by a connecting structure, and the middle section 31b and the rear section 31c are also movably connected by a connecting structure. Additionally, in this embodiment, three adsorption modules 33 are provided, respectively located at the bottom of the front section 31a, the middle section 31b, and the rear section 31c.
[0065] In this embodiment, the drive module 32 is installed in the middle section 31b of the frame 31. When the drive module 32 is working, it drives the front section 31a, the middle section 31b and the rear section 31c to move simultaneously.
[0066] It should be noted that in the embodiment, the adsorption modules 33 are arranged in three, and the three adsorption modules 33 correspond to the front section 31a, the middle section 31b and the tail section 31c of the vehicle frame 31 one by one. However, in some other embodiments, the adsorption modules 33 can also be arranged in more than three, for example, can be arranged in four, five or six, etc. The number of adsorption modules 33 more than three is also arranged in the front section 31a, the middle section 31b and the tail section 31c of the vehicle frame 31.
[0067] It should be noted that in the embodiment, the vehicle frame 31 includes three sections (i.e., the front section 31a, the middle section 31b and the tail section 31c), but in some other embodiments, the vehicle frame 31 can also be more than three sections. For example, the vehicle frame 31 can be arranged in four sections, which respectively include the front section 31a, the first middle section, the second middle section and the tail section 31c, and each section is also movably connected through the connecting structure. Of course, if the vehicle frame 31 is more than three sections, the number of adsorption modules 33 is also more than three, so as to ensure that each section has at least one adsorption module 33.
[0068] The connecting structure in the embodiment is a hinge 31d. The front section 31a and the middle section 31b are movably connected through the hinge 31d, and the front section 31a and the middle section 31b can rotate around the hinge 31d. The middle section 31b and the tail section 31c are movably connected through the hinge 31d, and the middle section 31b and the tail section 31c can rotate around the hinge 31d.
[0069] The specific process of the vehicle frame 31 crossing the gap will be introduced below: when crossing the gap, the front section 31a of the vehicle frame 31 first contacts the frame of the photovoltaic panel. Due to the existence of the frame, the front section 31a of the vehicle frame 31 is lifted by the frame of the photovoltaic panel to form an elevation angle. At this time, since the front section 31a of the vehicle frame 31 and the middle section 31b of the vehicle frame 31 are movably connected through the hinge 31d, the middle section 31b of the vehicle frame 31 is less affected by the front end, and the adsorption module 33 installed on the middle section 31b of the vehicle frame 31 can still maintain a good adsorption state with the photovoltaic panel, avoiding the separation of the vehicle frame 31 and the photovoltaic panel array. Then, the front section 31a of the vehicle frame 31 is pushed by the driving module 32 to continue to move forward, and the front section 31a of the vehicle frame 31 reaches the adjacent photovoltaic panel, and the middle section 31b of the vehicle frame 31 crosses to the gap. Then, the front section 31a and the middle section 31b of the vehicle frame 31 are pushed by the driving module 32 to continue to move forward, and the middle section 31b of the vehicle frame 31 reaches the adjacent photovoltaic panel. Finally, the tail section 31c of the vehicle frame 31 is also driven by the driving module 32 to reach the adjacent photovoltaic panel.
[0070] The above only is the embodiment of the present application, and the well-known specific structure and characteristics and other common knowledge in the scheme are not described too much here. It should be pointed out that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
