[0039] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0040] Reference below Figure 1-Figure 10 A photovoltaic cleaning device 100 according to an embodiment of the present application is described. The photovoltaic cleaning device 100 is used to clean photovoltaic equipment to reduce dust attached to the surface of the photovoltaic equipment and ensure the efficiency of the photovoltaic equipment in converting the solar radiation capacity into electrical energy.

[0041] It can be understood that photovoltaic equipment uses the principle of the photovoltaic effect to convert solar energy into electrical energy. Photovoltaic panels 200 are provided in the photovoltaic equipment. Photovoltaic panels 200 are used to receive sunlight. If dust adheres to the photovoltaic panels 200, the dust will affect the effect of the photovoltaic panels 200 in receiving solar energy, resulting in a decrease in the power generation efficiency of the photovoltaic equipment.

[0042] The photovoltaic cleaning device 100 according to the embodiment of the present application includes: a frame 1, a cleaning device 4, a first walking device 2 and a second walking device 3.

[0043] like Figure 1 As shown, the cleaning device 4 is installed on the frame 1, and the frame 1 is provided with a plurality of installation positions arranged along the first direction. The first walking device 2 and the second walking device 3 are respectively installed to the frame 1, and the first walking device 2 and the second walking device 3 are spaced apart in the first direction, and the first walking device 2 and the second walking device 3 are used to cooperate with the walking of the photovoltaic equipment to realize the walking of the photovoltaic cleaning device 100 relative to the photovoltaic equipment, so that the photovoltaic cleaning device 100 can clean the photovoltaic equipment in the walking state, thereby improving the cleaning effect of the photovoltaic cleaning device 100 on the photovoltaic equipment.

[0044] At least one of the first walking device 2 and the second walking device 3 is installed to the frame 1 through the installation position, so that the distance between the first walking device 2 and the second walking device 3 in the first direction is adjustable. Therefore, the first walking device 2 and the second walking device 3 can be matched with photovoltaic panels 200 of various sizes by adjusting the relative position between the first walking device 2 and the second walking device 3 in the first direction, thereby improving the versatility of the photovoltaic cleaning device 100.

[0045] It can be understood that the frame 1 is an installation carrier for the cleaning device 4, the first walking device 2 and the second walking device 3. The cleaning device 4 can be fixed in position relative to the frame 1. By adjusting the distance between the first walking device 2 and the second walking device 3, the photovoltaic cleaning device 100 can be matched with photovoltaic panels 200 of various sizes.

[0046] It should be further explained that the walking action of the photovoltaic cleaning device 100 relative to the photovoltaic equipment is realized by the first walking device 2 and the second walking device 3. In order to ensure the walking stability of the first walking device 2 and the second walking device 3 on the photovoltaic panel 200, the first walking device 2 and the second walking device 3 are usually arranged near the edge of the photovoltaic panel 200 to enhance the supporting stability of the first walking device 2 and the second walking device 3 on the frame 1 and the cleaning device 4.

[0047] Meanwhile, at least one of the first walking device 2 and the second walking device 3 is installed to the frame 1 through the installation position, including various embodiments. For example, both the first walking device 2 and the second walking device 3 can be configured to be installed and fixed to the frame 1 through the installation position; the first walking device 2 is configured to be installed and fixed to the frame 1 through the installation position, and the second walking device 3 is fixed to the frame 1 through other installation structures; the second walking device 3 is configured to be installed and fixed to the frame 1 through the installation position, and the first walking device 2 is fixed to the frame 1 through other installation structures.

[0048] As long as one of the first walking device 2 and the second walking device 3 cooperates with one of the multiple installation positions, the relative positions of the first walking device 2 and the second walking device 3 in the first direction can be adjusted.

[0049] It should be noted that the distance between the first walking device 2 and the second walking device 3 in the first direction determines the span of the photovoltaic cleaning device 100. The span of the photovoltaic cleaning device 100 can be adjusted by adjusting the distance between the first walking device 2 and the second walking device 3, so that the photovoltaic cleaning device 100 can match photovoltaic equipment of various sizes.

[0050] In a specific embodiment of the present application, the first walking device 2 is fixed to one end of the frame 1 in the first direction, and the position of the first walking device 2 relative to the frame 1 is fixed, and the second walking device 3 is connected and matched with one of the multiple installation positions and installed on the frame 1. The present application takes this embodiment as an example to describe that the positions of the first walking device 2 and the second walking device 3 in the first direction are adjustable.

[0051] The second walking device 3 is installed on the frame 1 by cooperating with one of the multiple installation positions. It can be understood that when the second walking device 3 is connected with different installation positions, the distance between the second walking device 3 and the first walking device 2 in the first direction will also be adjusted accordingly, so that the second walking device 3 is installed at the corresponding installation position to adjust the relative position between the first walking device 2 and the second walking device 3, so that the photovoltaic cleaning device 100 can be adapted to photovoltaic devices of various sizes, thereby improving the versatility of the photovoltaic cleaning device 100.

[0052] It should be noted that the photovoltaic equipment receives sunlight through the photovoltaic panels 200. At present, the size of photovoltaic panels on the market is not standardized enough, and the sizes of photovoltaic panels 200 in different photovoltaic equipment are different. The specific specifications are: 2256mm, 2278mm, 2384mm, 2465mm, etc. In the related technology, corresponding to the photovoltaic panels 200 of different sizes, it is necessary to design photovoltaic cleaning equipment of corresponding sizes to ensure the compatibility of the photovoltaic cleaning equipment with the photovoltaic panels 200, so that only one photovoltaic cleaning equipment cannot meet the walking and cleaning needs of photovoltaic panels 200 of various sizes. When cleaning photovoltaic equipment of different sizes, it is necessary to use multiple photovoltaic cleaning equipment, resulting in a high cleaning cost of the photovoltaic equipment.

[0053] In the present application, a plurality of mounting positions for installing walking devices are formed on the frame 1. By arranging the walking devices at different mounting positions, the relative positions of the first walking device 2 and the second walking device 3 in the first direction can be adjusted, thereby facilitating adjusting the first walking device 2 and the second walking device 3 to a distance suitable for cooperating with photovoltaic equipment of corresponding sizes, thereby achieving span adjustment of the photovoltaic cleaning device 100, thereby ensuring the walking effect of the photovoltaic cleaning device 100 on the photovoltaic equipment, and then matching the photovoltaic cleaning device 100 with photovoltaic equipment of various sizes.

[0054] Therefore, the photovoltaic cleaning device 100 in the present application can be matched with photovoltaic panels 200 of various sizes, thereby meeting the cleaning needs of photovoltaic equipment of various sizes, and reducing the cleaning cost of photovoltaic equipment by improving the adaptability of the photovoltaic cleaning device 100.

[0055] It should be noted that the number of mounting positions is not specifically limited here, for example: the first walking device 2 is fixed on the frame 1 and the second walking device 3 is mounted to the frame 1 through the mounting positions, that is, the position of the first walking device 2 relative to the frame 1 is not adjustable, and the second walking device 3 can be mounted to the frame 1 by cooperating with the mounting positions. In this case, there are at least two mounting positions for cooperating with the second walking device 3.

[0056] Reference Figure 1 , the cleaning length of the cleaning device 4 in the first direction is not less than the maximum distance between the first walking device 2 and the second walking device 3 in the first direction. Among them, the walking device (such as the first walking device 2 and the second walking device 3 mentioned above) needs to contact and cooperate with the photovoltaic panel 200 to achieve the walking action, that is, the cleaning length of the cleaning device 4 can fully cover the photovoltaic panel 200 to ensure the cleaning effect of the photovoltaic panel 200.

[0057] It should be noted that when the photovoltaic cleaning device 100 is applied to a photovoltaic device, the first walking device 2 and the second walking device 3 are arranged in the vertical direction, that is, one of the first walking device 2 and the second walking device 3 is used to cooperate with the upper edge limit of the photovoltaic panel 200, and the other of the first walking device 2 and the second walking device 3 is used to cooperate with the lower edge limit of the photovoltaic panel 200. In this application, the first walking device 2 is described as the lower walking device and the second walking device 3 is described as the upper walking device.

[0058] Among them, the photovoltaic panel 200 is usually arranged in a tilted posture from top to bottom. When the photovoltaic cleaning device 100 is arranged on the photovoltaic panel 200, the limiting structure (such as: limiting roller, etc.) in the second walking device 3 can be kept in contact with the upper edge of the photovoltaic panel 200, and the limiting structure (such as: limiting roller, etc.) in the first walking device 2 can reserve a certain gap between the lower edge of the photovoltaic panel 200 to ensure the passability of the photovoltaic cleaning device 100 on the photovoltaic panel 200.

[0059] like Figure 3 As shown, in some embodiments of the present application, the first walking device 2 includes: a first mounting frame 21 and a first walking mechanism 22, the first mounting frame 21 is connected to the frame 1, the first walking mechanism 22 is installed on the first mounting frame 21, and the first walking mechanism 22 is used to cooperate with the walking of the photovoltaic device, so as to drive the side of the frame 1 connected to the first mounting frame 21 to walk through the first walking mechanism 22.

[0060] The first mounting frame 21 is a mounting carrier of the first walking mechanism 22, and the first walking mechanism 22 is mounted on the frame 1 through the first mounting frame 21. When the first walking mechanism 22 moves relative to the photovoltaic device, the first walking mechanism 22 drives the first mounting frame 21, and further drives the frame 1 to move synchronously through the first mounting frame 21. The frame 1 can drive the cleaning device 4 to move together, thereby cleaning the photovoltaic device.

[0061] Reference Figure 3 and Figure 8 , the position of the first mounting frame 21 relative to the frame 1 is fixed, that is, the position of the first mounting frame 21 on the frame 1 is not adjustable. The first mounting frame 21 can be connected and fixed to the frame 1 by a connecting member (such as a latch, a bolt, etc.), and can also be fixedly connected to the frame 1 by welding, which is not specifically limited here.

[0062] like Figure 3 and Figure 8As shown, in a further embodiment of the present application, the first walking mechanism 22 includes a first walking wheel 221 and a second walking wheel 222, the first walking wheel 221 is mounted on the first mounting frame 21, and the axial direction of the first walking wheel 221 is arranged parallel to the first direction, the second walking wheel 222 is mounted on the first mounting frame 21, and the axial direction of the second walking wheel 222 is parallel to the axial direction of the first walking wheel 221. The first walking wheel 221 and the second walking wheel 222 are respectively arranged on both sides of the frame 1.

[0063] It can be understood that the first walking wheel 221 and the second walking wheel 222 are used to roll with the surface to be cleaned of the photovoltaic equipment, so that the first walking mechanism 22 drives the first mounting frame 21, the frame 1 and the cleaning device 4 to move relative to the photovoltaic equipment, and the first walking wheel 221 and the second walking wheel 222 are arranged on both sides of the frame 1 to provide good support for the frame 1 and enhance the stability of the frame 1 during the movement relative to the photovoltaic equipment.

[0064] like Figure 3 and Figure 8 As shown, in some embodiments of the present application, the first walking device 2 also includes a first limiting roller 23, which is installed on the first mounting frame 21, and when the photovoltaic cleaning device 100 cooperates with the photovoltaic equipment, the first limiting roller 23 is arranged on the first side of the photovoltaic equipment in a first direction, so as to improve the stability of the photovoltaic cleaning device 100 when walking relative to the photovoltaic panel 200 by limiting the cooperation with the photovoltaic equipment through the first limiting roller 23.

[0065] In a further embodiment of the present application, the axial direction of the first limiting roller 23 is perpendicular to the walking surface of the photovoltaic cleaning device 100 on the photovoltaic equipment, so that the first limiting roller 23 is limited and matched with the edge (such as the lower edge) of the photovoltaic panel 200. The "walking surface of the photovoltaic cleaning device 100" refers to the side surface of the photovoltaic panel 200 used to cooperate with the walking wheel, which is also the side surface of the photovoltaic panel 200 to be cleaned, that is, the upper surface of the photovoltaic panel 200.

[0066] like Figure 1 and Figure 6 As shown, in some embodiments of the present application, the second walking device 3 includes: a second mounting frame 31 and a second walking mechanism 32, the second mounting frame 31 is connected to the mounting position, the second walking mechanism 32 is installed on the second mounting frame 31, and is used to cooperate with the walking of the photovoltaic device.

[0067] The second mounting frame 31 is a mounting carrier of the second walking mechanism 32, and the second walking mechanism 32 is mounted on the frame 1 through the second mounting frame 31. When the second walking mechanism 32 moves relative to the photovoltaic device, the second walking mechanism 32 drives the second mounting frame 31, and further drives the frame 1 to move synchronously through the second mounting frame 31. The frame 1 can drive the cleaning device 4 to move together, thereby cleaning the photovoltaic device.

[0068] Reference Figure 1 and Figure 6 The second mounting frame 31 is installed to the frame 1 by connecting and cooperating with the mounting position, and the second mounting frame 31 can be connected and cooperated with any one of the multiple mounting positions to adjust the span of the photovoltaic cleaning device 100 according to the size requirements of the photovoltaic equipment.

[0069] like Figure 2 and Figure 7 As shown, in some embodiments of the present application, the frame 1 is provided with a plurality of groups of mounting holes 104 arranged along a first direction, and at least one group of mounting holes 104 constitutes a mounting position.

[0070] It should be noted that a group of mounting holes 104 includes at least one mounting hole 104, that is, each group of mounting holes 104 may be provided with one, two or three mounting holes 104, and the number of mounting holes 104 included in each group of mounting holes 104 is not specifically limited herein. Figure 2 Each group of mounting holes 104 includes two mounting holes 104 arranged in the vertical direction. By increasing the number of mounting holes 104 in each group of mounting holes 104, the connection reliability between the second mounting frame 31 and the frame 1 can be improved.

[0071] It should be further explained that one mounting position can be composed of at least one group of mounting holes 104 , that is, when the second mounting frame 31 is connected and matched with the frame 1 , it can be connected and matched with one or more groups of mounting holes 104 at the same time.

[0072] Reference Figure 2 In a specific embodiment, a connection structure (such as a connection plate, etc.) corresponding to the mounting position is provided on the second mounting frame 31. When the second mounting frame 31 is connected to the frame 1 through the connection structure, the connection structure corresponds to the two groups of mounting holes 104. The two groups of mounting holes 104 are arranged along the first direction to form a mounting position, and the two groups of mounting holes 104 can be arranged at intervals, that is, one or more groups of mounting holes 104 can be arranged between the two groups of mounting holes 104, which is not specifically limited here. When a mounting position is composed of multiple groups of mounting holes 104, the second mounting frame 31 can be connected to the frame 1 through a larger number of mounting holes 104, which can further improve the connection reliability between the second mounting frame 31 and the frame 1.

[0073] Reference Figure 7 In another specific embodiment, the second mounting frame 31 is provided with a connection structure corresponding to the mounting position (e.g., a connection seat, which can be sleeved on the beam structure of the frame 1). When the second mounting frame 31 is connected to the frame 1 through the connection structure, the connection structure corresponds to a group of mounting holes 104. In other words, the second mounting frame 31 is connected to the frame 1 only through a group of mounting holes 104.

[0074] like Figure 1 and Figure 6 As shown, in some embodiments of the present application, the second walking mechanism 32 includes a third walking wheel 321 and a fourth walking wheel 322, the third walking wheel 321 and the fourth walking wheel 322 are installed on the second mounting frame 31, and the third walking wheel 321 and the fourth walking wheel 322 are respectively arranged on both sides of the frame 1.

[0075] It can be understood that the third walking wheel 321 and the fourth walking wheel 322 are used to roll with the surface to be cleaned of the photovoltaic equipment, so that the second walking mechanism 32 drives the second mounting frame 31, the frame 1 and the cleaning device 4 to move relative to the photovoltaic equipment, and the third walking wheel 321 and the fourth walking wheel 322 are arranged on both sides of the frame 1 to provide good support for the frame 1 and enhance the stability of the frame 1 during the movement relative to the photovoltaic equipment.

[0076] Reference Figure 1 The photovoltaic cleaning device 100 of the present application is provided with four walking wheels, namely a first walking wheel 221, a second walking wheel 222, a third walking wheel 321 and a fourth walking wheel 322, so that the photovoltaic cleaning device 100 can form a four-point support on the photovoltaic panel 200, thereby improving the walking stability of the photovoltaic cleaning device 100 on the photovoltaic panel 200.

[0077] In a further embodiment of the present application, the second mounting frame 31 includes: a first sub-bracket 311 and a second sub-bracket 312, the first sub-bracket 311 and the second sub-bracket 312 are respectively connected to the frame 1, and the third running wheel 321 is installed on the first sub-bracket 311, and the fourth running wheel 322 is installed on the second sub-bracket 312. Thus, the third running wheel 321 and the fourth running wheel 322 are respectively installed to the frame 1 through the first sub-bracket 311 and the second sub-bracket 312, and dividing the second mounting frame 31 into two independent bracket structures can reduce the structural complexity of the second mounting frame 31 and facilitate the assembly of the second mounting frame 31.

[0078] like Figure 6As shown, in some embodiments of the present application, the second mounting frame 31 includes: a first longitudinal beam 11 and a second longitudinal beam 12, the first longitudinal beam 11 extends along the first direction, the first longitudinal beam 11 is formed with a plurality of first mounting positions 102 arranged in sequence along the first direction, and the first sub-bracket 311 is connected to the first longitudinal beam 11 through the first mounting position 102; the second longitudinal beam 12 extends along the first direction, the second longitudinal beam 12 is formed with a plurality of second mounting positions 103 arranged in sequence along the first direction, and the second sub-bracket 312 is connected to the second longitudinal beam 12 through the second mounting position 103. The first longitudinal beam 11 and the second longitudinal beam 12 are arranged at intervals in the walking direction of the photovoltaic cleaning device 100, and the cleaning device 4 is arranged between the first longitudinal beam 11 and the second longitudinal beam 12.

[0079] It should be noted that the installation position includes the first installation position 102 and the second installation position 103 mentioned above.

[0080] Reference Figure 6 The first sub-bracket 311 is assembled to the first longitudinal beam 11 by cooperating with one of the plurality of first mounting positions 102, and the second sub-bracket 312 is assembled to the second longitudinal beam 12 by cooperating with one of the plurality of second mounting positions 103, so that the positions of the first sub-bracket 311 and the second sub-bracket 312 are adjustable in the first direction of the frame 1.

[0081] The third running wheel 321 is installed to the first longitudinal beam 11 through the first sub-bracket 311, and the fourth running wheel 322 is installed to the second longitudinal beam 12 through the second sub-bracket 312. That is, the positions of the third running wheel 321 and the fourth running wheel 322 can also be adjusted accordingly with the installation positions of the first sub-bracket 311 and the second sub-bracket 312 on the frame 1. Figure 6 The first sub-bracket 311 and the second sub-bracket 312 are arranged at the same position of the frame 1 in the first direction, so that the first running wheel 221 and the second running wheel 222 are arranged colinearly in the traveling direction.

[0082] like Figure 6 As shown, in some embodiments of the present application, the first sub-bracket 311 is provided with a first connecting seat 3112, the first connecting seat 3112 is sleeved on the first longitudinal beam 11, and the first connecting seat 3112 is used to connect and cooperate with the first mounting position 102; the second sub-bracket 312 is provided with a second connecting seat 3122, the second connecting seat 3122 is sleeved on the second longitudinal beam 12, and is used to connect and cooperate with the second mounting position 103.

[0083] The first connection seat 3112 can slide along the first direction on the first longitudinal beam 11 to be adjusted to a position suitable for connection and cooperation with the first installation position 102, and the second connection seat 3122 can slide along the first direction on the second longitudinal beam 12 to be adjusted to a position suitable for connection and cooperation with the second installation position 103. The adjustment method of the first connection seat 3112 and the second connection seat 3122 relative to the frame 1 is simple, and the sleeve matching method can effectively prevent the first connection seat 3112 and the second connection seat 3122 from falling out.

[0084] Furthermore, the cross-sections of the first longitudinal beam 11 and the second longitudinal beam 12 in the extension direction (also the first direction) are polygonal, and accordingly, the first connecting seat 3112 and the second connecting seat 3122 are also formed with polygonal grooves adapted to the cross-sectional shapes of the longitudinal beams, thereby preventing the first connecting seat 3112 from rotating relative to the first longitudinal beam 11 and the second connecting seat 3122 from rotating relative to the second longitudinal beam 12, thereby achieving a positioning effect.

[0085] Reference Figure 7 When the first mounting position 102 and the second mounting position 103 are respectively constructed to be composed of a group of mounting holes 104, a through-hole structure is also formed on the first connection seat 3112 and the second connection seat 3122. The through-hole structure is used to correspond to the mounting holes 104 and to allow a connecting member (such as a bolt, etc.) to pass through, so as to fix the first connection seat 3112 and the second connection seat 3122 to the frame 1 through a threaded connection member. Among them, two mounting holes 104 are provided in a group of mounting holes 104.

[0086] In some embodiments of the present application, the first sub-bracket 311 and the second sub-bracket 312 are respectively arranged on both sides of the frame 1 in the first direction, and the two side walls of the frame 1 in the first direction are respectively provided with a first installation position 102 and a second installation position 103.

[0087] The first sub-bracket 311 is provided with a first connecting plate 3111, and the first connecting plate 3111 is used to connect and cooperate with the first installation position 102; the second sub-bracket 312 is provided with a second connecting plate 3121, and the second connecting plate 3121 is used to connect and cooperate with the second installation position 103. Thus, the first sub-bracket 311 and the second sub-bracket 312 can be installed on the frame 1 respectively.

[0088] Furthermore, the first connecting plate 3111 and the second connecting plate 3121 are respectively formed with a through-hole structure matching the mounting hole 104, and the through-hole structure is used for connecting parts (such as bolts, etc.) to pass through, so as to connect and fix the first connecting plate 3111 and the second connecting plate 3121 to the frame 1 through the connecting parts.

[0089] like Figure 2As shown, in a further embodiment of the present application, the first sub-bracket 311 is provided with a first mounting groove open to one side of the second sub-bracket 312, and a portion of the frame 1 is arranged in the first mounting groove; the second sub-bracket 312 is provided with a second mounting groove open to one side of the first sub-bracket 311, and a portion of the frame 1 is arranged in the second mounting groove, and the openings of the first mounting groove and the second mounting groove are arranged relative to each other.

[0090] Among them, the first mounting groove and the second mounting groove are both constructed as U-shaped grooves, and the openings of the first mounting groove and the second mounting groove are arranged relatively relatively. The frame 1 can be entered from the opening sides of the first mounting groove and the second mounting groove to install the first sub-bracket 311 and the second sub-bracket 312 to the frame 1 from two directions respectively. The installation process of the first sub-bracket 311 and the second sub-bracket 312 is relatively independent, which can reduce the difficulty of assembling the first sub-bracket 311 and the second sub-bracket 312.

[0091] At the same time, two opposite walls of the first mounting groove in the vertical direction can fit with the upper wall and the lower wall of the frame 1 to position the first sub-bracket 311 and the frame 1 to further reduce the difficulty of assembling the first sub-bracket 311 and the frame 1.

[0092] The second sub-bracket 312 has the same structure as the first sub-bracket 311 , and is a symmetrical structure of the first sub-bracket 311 , that is, the first sub-bracket 311 and the second sub-bracket 312 are symmetrically arranged on both sides of the frame 1 .

[0093] like Figure 1 As shown, in some embodiments of the present application, the second walking device 3 also includes a second limiting roller 33, and the second limiting roller 33 is installed on the second mounting frame 31. Moreover, when the photovoltaic cleaning device 100 cooperates with the photovoltaic equipment, the second limiting roller 33 is arranged on the second side of the photovoltaic equipment in the first direction to cooperate with the side wall of the photovoltaic panel 200 to improve the stability of the photovoltaic cleaning device 100 during the walking process.

[0094] It is understandable that the second limiting roller 33 can roll with the side wall of the photovoltaic panel 200 to play a supporting and limiting role during the movement of the photovoltaic cleaning device 100 .

[0095] Reference Figure 1 and Figure 6 The first limiting roller 23 and the second limiting roller 33 are respectively arranged on one side of the photovoltaic panel 200, which are also the two sides in the walking direction of the photovoltaic cleaning device 100, so that the stability of the photovoltaic cleaning device 100 during the movement is improved by the first limiting roller 23 and the second limiting roller 33 and the photovoltaic panel 200.

[0096] Among them, the first limiting roller 23 and the second limiting roller 33 can cooperate with the side wall of the photovoltaic panel 200 to improve the stability of the photovoltaic cleaning device 100 during the walking process and prevent the photovoltaic cleaning device 100 from falling from the photovoltaic equipment.

[0097] like Figure 1 and Figure 6 As shown, in some embodiments of the present application, the cleaning device 4 includes a roller brush 41, which is used to clean the photovoltaic device, and the axial direction of the roller brush 41 is parallel to the first direction. The roller brush 41 can rotate around its central axis to achieve a cleaning action.

[0098] It can be understood that, compared with only a single row of bristle structures fixed to the frame 1, the rollable roller brush 41 in the present application has a better cleaning effect, and the dust attached to the surface of the photovoltaic panel 200 can be fully removed by the rotating bristles.

[0099] In some embodiments of the present application, the cleaning device 4 further includes a driving motor 42, which is mounted on the frame 1 and connected to one axial end of the roller brush 41, so that the roller brush 41 is driven to rotate by the driving motor 42 to achieve the cleaning action of the roller brush 41. The driving motor 42 can be fixed to the frame 1 by a mounting structure such as a mounting frame arranged by hoisting, and the mounting and matching method of the driving motor 42 and the frame 1 is not specifically limited here, and it is sufficient to arrange the driving motor 42 in a position suitable for driving the roller brush 41 to rotate.

[0100] Reference Figure 3 and Figure 8 The cleaning device 4 is further provided with a bearing 43, which is disposed on the first mounting frame 21 and is used to support the other end of the roller brush 41 to improve the stability of the roller brush 41 during rotation.

[0101] In some embodiments of the present application, the photovoltaic cleaning device 100 also includes an electrical control box 5, which is installed on the frame 1. The electrical control box 5 can be used to control the operating status of the equipment in the photovoltaic cleaning device 100, such as: controlling the cleaning device 4 to run or stop running; controlling the first walking device 2.

[0102] Reference Figure 1-Figure 10 Describe the span adjustment process of the photovoltaic cleaning device 100 according to the embodiment of the present application:

[0103] When the span of the photovoltaic cleaning device 100 needs to be increased, the connecting piece used to fix the second mounting frame 31 (the first sub-bracket 311 and the second sub-bracket 312) is removed, and the second mounting frame 31 is driven to move along the first direction away from the first mounting frame 21. After the second mounting frame 31 is adjusted to the preset position, the second mounting frame 31 can be further fixed by the connecting piece.

[0104] When the span of the photovoltaic cleaning device 100 needs to be reduced, the connecting piece used to fix the second mounting frame 31 (the first sub-bracket 311 and the second sub-bracket 312) is removed, and the second mounting frame 31 is driven to move along the first direction toward the side close to the first mounting frame 21. After the second mounting frame 31 is adjusted to the preset position, the second mounting frame 31 can be further fixed by the connecting piece.

[0105] In the present application, the position adjustment of the second mounting frame 31 is simple, and the span of the photovoltaic cleaning device 100 can be adjusted to meet the walking requirements of the photovoltaic cleaning device 100 on photovoltaic equipment of different sizes.
