DETAILED DESCRIPTION

[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0034] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0035] With the development of new energy technologies, photovoltaic power generation, as an important type of new energy power generation, has also made great progress in terms of technology level and application scale. Photovoltaic panels are the core components of photovoltaic power generation systems and play a core role in photoelectric conversion. The photoelectric conversion efficiency of photovoltaic panels directly determines the operating energy efficiency of photovoltaic power generation systems. The surface cleanliness of photovoltaic panels has a great influence on the photoelectric conversion efficiency of photovoltaic panels. Regularly cleaning the surface of photovoltaic panels to remove dust and stains will help improve the conversion efficiency of photovoltaic panels.

[0036] Photovoltaic power generation components usually include a large number of photovoltaic panel components arranged in an array. Each photovoltaic panel component is composed of multiple panel units. When performing cleaning operations, the panel units need to be cleaned one by one, which is a lot of work.

[0037] In order to solve this problem, some special cleaning equipment has begun to appear. Most of these cleaning equipment include a walking device, a rolling brush and an adsorption device. The walking device drives the equipment to move on the photovoltaic panel assembly to change the cleaning position, and the rolling brush and the adsorption device cooperate with each other to clean the photovoltaic panel assembly and remove dust on its surface.

[0038] However, after the cleaning device has been working for a period of time, the rolling brush will inevitably wear out, and the rolling brush is fixed on the device and its position cannot be adjusted. This makes it difficult for the rolling brush to effectively contact the surface of the photovoltaic panel assembly when cleaning foreign matter on the surface of the photovoltaic panel assembly, which greatly reduces the cleaning effect of the rolling brush on the photovoltaic panel assembly. At the same time, although the adsorption device cooperates with the rolling brush to remove most of the dust, it is very difficult to remove some sticky foreign matter, which further reduces the cleaning effect of the cleaning device.

[0039] In order to avoid the above-mentioned problems, the present application provides a photovoltaic panel assembly cleaning device, which, on the one hand, can enable the rolling brush to automatically adjust its position in the vertical direction, so that it always keeps in contact with the surface of the photovoltaic panel assembly during operation. Even if the rolling brush is worn, the cleaning effect of the rolling brush on the photovoltaic panel assembly can be guaranteed. On the other hand, a spray cleaning component is added, which can flush foreign matter on the surface of the photovoltaic panel assembly. The spray cleaning component, in combination with the rolling brush, can further enhance the cleaning effect of the photovoltaic panel assembly.

[0040] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0041] See also Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a photovoltaic panel assembly cleaning device, which, like the existing cleaning equipment, includes a device body, a driving structure 6, and a rolling brush 11.

[0042] Among them, the device body is mainly used to support the driving structure 6, the rolling brush 11 and the connecting structure, and the driving structure 6 mainly provides driving force for the device body, so that the device body can move freely and change its position on the surface of the photovoltaic panel assembly, thereby cleaning the photovoltaic panel assembly. The rolling brush 11 can roll in contact with the photovoltaic panel assembly when the device body moves, so that foreign matter on the surface of the photovoltaic panel assembly no longer adheres to the surface of the photovoltaic panel assembly, thereby cleaning the photovoltaic panel assembly.

[0043] For example, the moving direction of the cleaning device can be Figure 1 In the Y-axis direction, the rolling brush 11 is along Figure 1 Extends in the X-axis direction.

[0044] Of course, it is understandable that, consistent with existing cleaning equipment, the device body may also include structures such as an adsorption device, which is used to cooperate with the rolling brush 11. When the rolling brush 11 prevents foreign matter from adhering to the surface of the photovoltaic panel assembly, the foreign matter is removed from the surface of the photovoltaic panel assembly to clean the photovoltaic panel assembly. Adsorption devices and the like are relatively common, and their setting method is also relatively conventional, so they will not be elaborated here.

[0045] The biggest difference of this embodiment is that a connecting structure is also provided to connect the rolling brush 11 and the device body through the connecting structure.

[0046] Specifically, the connection structure includes a fixed block 10, at least one sliding rod 8 and at least one buffer spring 9, the rolling brush 11 is rotatably connected to the fixed block 10, and the sliding rod 8 is slidably connected to the device body, which can move up and down relative to the device body, that is, along the Figure 1 The sliding rod 8 extends to one end outside the device body and is connected to the fixed block 10, so that the rolling brush 11 can automatically float up and down relative to the device body. Of course, the floating distance of the rolling brush 11 can be limited by limiting the distance that the sliding rod 8 can move up and down relative to the device body. The buffer spring 9 extends in the same direction as the sliding rod 8, that is, both are along the Figure 1 The buffer spring 9 extends in the Z-axis direction, one end of the buffer spring 9 is connected to the fixed block 10, and the other end is connected to the device body, so that the rolling brush 11 can always be kept in contact with the photovoltaic panel assembly through the compression force provided by the buffer spring 9, thereby improving the cleaning effect.

[0047] Among them, the sliding rod 8 and the fixed block 10 can be connected by screws, mortise and tenon, threaded connection, etc., or the two can be directly formed as one piece, as long as the fixed block 10 can be effectively connected to the rolling brush 11 and the fixed block 10 can limit the buffer spring 9.

[0048] Exemplarily, the buffer spring 9 can be arranged on one side of the sliding rod 8, that is, it is parallel to the sliding rod 8. The sliding rod 8 can limit the moving direction of the rolling brush 11, and the buffer spring 9 can provide a clamping force for the rolling brush 11, so that the rolling brush 11 always remains in contact with the photovoltaic panel assembly during use.

[0049] For example, the buffer spring 9 can be sleeved on the outside of the sliding rod 8. Such a configuration can reduce the space occupied by the connecting structure and also protect the buffer spring 9.

[0050] Exemplarily, each connection structure may include two buffer springs 9 and two sliding rods 8. The sliding rods 8 are arranged side by side, which on the one hand enhance the supporting effect of the rolling brush 11, and on the other hand also help to enhance the fitting effect between the rolling brush 11 and the surface of the photovoltaic panel assembly.

[0051] Of course, the connection structure is only illustrated here. Each connection structure can also include three, four or even more buffer springs 9 and sliding rods 8. The specific number is based on the use requirements of the cleaning device, and the embodiments of the present application are not limited here.

[0052] In addition, the number and installation positions of the connection structures may also be adjusted according to actual conditions, and this embodiment does not limit them.

[0053] Exemplarily, two connection structures can be provided, which are arranged along the extension direction of the rolling brush 11 and can be provided at any position of the rolling brush 11 as long as the position of the rolling brush 11 in the vertical direction can be effectively restricted.

[0054] Illustratively, a connecting structure may be provided at each end of the rolling brush 11, which can not only effectively support the rolling brush 11, but also avoid a position with poor cleaning effect in the middle of the rolling brush 11, thereby facilitating the rolling brush 11 to clean the photovoltaic panel assembly.

[0055] In this embodiment, the fixed block 10 is rotatably connected to the rolling brush 11, which can support the rolling brush 11 without affecting the rotation of the rolling brush 11; one end of the sliding rod 8 is connected to the fixed block 10 to support the fixed block 10, and the other end is slidably connected to the device body, so that the sliding rod 8 can move up and down relative to the device body, thereby allowing the rolling brush 11 to move up and down relative to the device body, and at the same time, the amplitude of the up and down movement of the rolling brush 11 can be limited by the movable distance of the sliding rod 8 relative to the device body; and the buffer spring 9 is connected to the device body at one end and the fixed block 10 at the other end, so that the buffer spring 9 applies a force to the fixed block 10, so that the fixed block 10 can move automatically during use, thereby allowing the rolling brush 11 to automatically adhere to the surface of the photovoltaic panel assembly. That is, this embodiment connects the rolling brush 11 and the device body by setting a connecting structure, so that the rolling brush 11 can automatically adjust its position in the vertical direction during the cleaning of the photovoltaic panel assembly, thereby making effective contact with the surface of the photovoltaic panel assembly, so as to ensure the cleaning effect of the photovoltaic panel assembly cleaning device on the photovoltaic panel assembly, and assist in improving the photoelectric conversion efficiency of the photovoltaic panel assembly.

[0056] For some possible implementations, see Figure 3As shown, the device body includes a connection block 7 located at the bottom of the device body, and a mounting groove is provided on the connection block 7. The mounting groove is provided with at least one opening toward the bottom of the device body, and a limit block is provided at the opening, and a through hole connected to the inside of the mounting groove is provided on the limit block. One end of the sliding rod 8 can extend into the mounting groove through the through hole, and the sliding rod 8 is slidably connected to the through hole, thereby limiting the moving direction of the sliding rod 8 through the through hole, that is, the sliding rod 8 can only move up and down in the mounting groove. Of course, the height of the mounting groove in the Z-axis direction limits the distance that the sliding rod 8 can move up and down. A positioning block is provided at one end of the sliding rod 8 extending into the mounting groove. The size of the positioning block is larger than the size of the through hole, so that the sliding rod 8 cannot be separated from the mounting groove. The two ends of the buffer spring 9 are respectively connected to the fixed block 10 and the limit block to adjust the position of the fixed block 10, so that the rolling brush 11 always keeps in contact with the photovoltaic panel assembly.

[0057] The limit block can be connected to the installation slot by threading, or can be detachably connected by screws, buckles, etc. Of course, the limit block can also be directly fixedly connected to the installation slot, but in a detachable connection mode, when the buffer spring 9 or the sliding rod 8 is damaged, the limit block can be directly disassembled for rapid repair and replacement, and the assembly difficulty and processing difficulty of the connection structure can also be reduced.

[0058] It is understandable that the above embodiments are merely examples of the connection method between the connection structure and the device body, and are not intended to limit it.

[0059] As a specific implementation of the drive structure 6, see Figure 2 As shown, the driving structure 6 includes a rotating shaft 3, a roller 15 and a motor 602. The rotating shaft 3 is rotatably installed at the bottom of the device body, and two rotating shafts 3 are arranged side by side. A roller 15 is arranged at each end of the rotating shaft 3. The outer surface of the roller 15 in contact with the photovoltaic panel assembly is covered with an anti-slip pad 16. Of course, the roller 15 can be an ordinary wheel or a universal wheel, as long as it can drive the device body to move. The motor 602 is installed on the device body, and the output shaft 603 of the motor 602 is connected to one of the two rotating shafts 3 through a transmission member to drive the rotating shaft 3 to rotate, thereby rotating the roller 15 and driving the device body to move on the surface of the photovoltaic panel assembly.

[0060] The extending direction of the rotating shaft 3 is the same as the extending direction of the rolling brush 11, so that when the rotating shaft 3 rotates and the device body moves, the rolling brush 11 rotates synchronously to clean the photovoltaic panel assembly.

[0061] In addition, after the surface of the roller 15 is wrapped with the anti-skid pad 16, the roller 15 can be prevented from slipping when the cleaning device is working.

[0062] Exemplarily, the anti-slip pad 16 can be a rubber sleeve sleeved on the outer circumference of the roller 15 , and the surface of the rubber sleeve is evenly distributed with a plurality of ridges, and the extending direction of the ridges is the same as the extending direction of the rotating shaft 3 .

[0063] For some possible implementations, see Figure 2 As shown, the device body also includes a protection box 2, and the motor 602 is installed in the protection box 2. A mounting block 601 can also be set in the protection box 2, and the free end of the output shaft 603 of the motor 602 is rotatably connected to the mounting block 601, and the output shaft 603 is supported by the mounting block 601. In this arrangement, the motor 602 can be protected by the protection box 2, reducing the probability of damage to the motor 602.

[0064] For some possible implementations, see Figure 2 and Figure 4 As shown, the transmission member is a belt 604, a first transmission wheel is arranged on the output shaft 603 of the motor 602, the first transmission wheel is located in the protection box 2, a second transmission wheel is arranged on the rotating shaft 3, one end of the belt 604 is sleeved on the first transmission wheel, and the other end passes through the protection box 2 and is sleeved on the second transmission wheel, so that when the motor 602 is started, the rotating shaft 3 rotates synchronously with the output shaft 603 of the motor 602. The device body also includes a protective cover 605, the rotating shaft 3 passes through the protective cover 605 and is rotatably connected with the protective cover 605, the second transmission wheel is located in the protective cover 605, and the part of the belt 604 extending to the outside of the protection box 2 is also located in the protective cover 605, so that the belt 604 and the second transmission wheel are effectively protected by the protective cover 605 to prevent foreign objects from entering, or foreign objects from colliding with the belt 604 and the second transmission wheel, so as to extend the service life of the cleaning device.

[0065] Exemplarily, the device body may also include a mounting plate 1, the protective box 2 is arranged on the top of the mounting plate 1 and supported by the mounting plate 1, and the rotating shaft 3, roller 15, rolling brush 11, and connecting structure are all arranged at the bottom of the mounting plate 1. When installing the belt 604, it is only necessary to open an opening for the belt 604 to pass through at the bottom of the protective box 2 and the corresponding position of the mounting plate 1. At the same time, one end of the protective cover 605 can be directly connected to the bottom of the mounting plate 1 and supported and fixed by the mounting plate 1. Of course, the protective cover 605 can also be directly connected to the protective box 2 and supported by the protective box 2.

[0066] Of course, it can be understood that the examples here are only used to illustrate the setting method of the protective box 2 and the protective cover 605, and the structure of the transmission parts, rather than to limit them. The protective box 2 and the protective cover 605 can be set at any position of the device body, and the transmission parts can also be any other transmission structure, as long as they can transmit normally and make the rotating shaft 3 and the output shaft 603 of the motor 602 rotate synchronously.

[0067] For some possible implementations, see Figure 2 As shown, a plurality of heat dissipation holes 12 can be provided on the protection box 2 to improve the heat dissipation effect of the motor 602. Of course, the heat dissipation holes 12 are preferably provided on the side of the protection box 2 to prevent foreign matter from falling into the protection box 2 from the top and to prevent foreign matter on the rolling brush 11 from being thrown into the protection box 2.

[0068] For some possible implementations, see Figure 1 As shown, in order to facilitate the maintenance and replacement of the equipment in the protective box 2, a maintenance port can be set on the protective box 2, for example, on the top or side of the protective box 2, and a cover 13 can be set corresponding to the maintenance port to control the opening and closing of the maintenance port, for example, it can be set as two flip covers that are relatively arranged and hinged to the protective box 2, and a handle 14 can also be set on the cover 13 to open or close the cover 13.

[0069] For some possible implementations, see Figure 1 As shown, the device body also includes a spray cleaning component 5 and a water pump 4, wherein the water pump 4 is used to connect to a water supply unit, such as a water tank, to send water into the spray cleaning component 5 to clean the photovoltaic panel assembly.

[0070] Among them, see Figure 4 and Figure 5 As shown, the spray cleaning assembly 5 includes a plurality of high-pressure nozzles 503, which are located below the mounting plate 1. The high-pressure nozzles 503 are evenly arranged along the extension direction of the rolling brush 11 to cooperate with the rolling brush 11 to clean the photovoltaic panel assembly.

[0071] Exemplarily, the high-pressure nozzle 503 can be configured as a duckbill nozzle to increase the flushing area and flushing effect of the water flow, thereby improving the cleaning effect on the photovoltaic panel assembly.

[0072] Of course, the high-pressure nozzle 503 may also be of other structures as long as it can effectively perform flushing. This embodiment is only used as an example for explanation and does not limit its structure.

[0073] Exemplarily, the spray cleaning component 5 can also include a water storage box 501 and a connecting pipe 502, the extension direction of the connecting pipe 502 is consistent with the extension direction of the rolling brush 11, and the high-pressure nozzle 503 is located on the side of the connecting pipe 502 close to the rolling brush 11, so that the spraying position of the high-pressure nozzle 503 corresponds to the cleaning position of the rolling brush 11, wherein one end of the connecting pipe 502 is connected to the water outlet of the water pump 4 through the water pipe 402, and the other end is connected to the water inlet of the water storage box 501, and the water inlet of the high-pressure nozzle 503 is connected to the water outlet of the water storage box 501, so as to enhance the spraying effect of the high-pressure nozzle 503 through the water storage box 501.

[0074] In some possible embodiments, the device body also includes a water inlet pipe 404 and a rotating sleeve 403. The rotating sleeve 403 is rotatably connected to the water pump 4, and the rotating sleeve 403 is connected to the water inlet of the water pump 4. The water inlet pipe 404 is installed on the rotating sleeve 403 and is connected to the water inlet of the water pump 4 through the rotating sleeve 403. That is, the water inlet pipe 404 can be freely rotated 360° in a horizontal plane relative to the water pump 4 through the rotating sleeve 403, and on the other hand, it can connect the water inlet of the water pump 4 with the water supply unit.

[0075] When cleaning the photovoltaic panel components, more water is needed. In order to reduce the weight of the cleaning device and avoid its impact on the photovoltaic panel components, a water supply unit separated from the cleaning device can be used to supply water. Of course, the water supply unit here does not only refer to movable devices such as water tanks, but can also refer to any equipment that can provide water sources such as tap water pipes, or rivers, lakes, etc. During the use of the cleaning device, the cleaning device will move. At this time, if the water inlet pipe 404 is pulled, it will automatically rotate in the direction of the water supply unit through the rotating sleeve 403, thereby avoiding the water inlet pipe 404 from twisting and deformation, so as to effectively avoid the situation where the water source cannot normally pass through the water pump 4 into the connecting pipe 502.

[0076] In some possible embodiments, the water pump 4 can be set on the top of the mounting plate 1, the water inlet pipe 404 is set on the top of the water pump 4, and the water supply pipe 402 connected to the spray assembly 5 can be set on the side of the water pump 4. The water supply pipe 402 can directly pass through the mounting plate 1 and connect with the connecting pipe 502 located under the mounting plate 1 to further prevent the water inlet pipe 404 from twisting and deforming.

[0077] Specifically, when using the photovoltaic panel assembly cleaning device of the embodiment of the present application, the water inlet pipe 404 is connected to the water supply unit, and then the motor 602 drives the rotating shaft 3 to rotate to move the cleaning device, and the spray cleaning assembly 5 connected to the water supply unit sprays a strong water flow through the high-pressure nozzle 503 to rinse the surface of the photovoltaic panel. At the same time, when the device moves, the rolling brush 11 rolls with the photovoltaic panel assembly, and cooperates with the high-pressure nozzle 503 to clean the photovoltaic panel assembly. In addition, since buffer springs 9 are provided at both ends of the rolling brush 11, when in use, the rolling brush 11 and the surface of the photovoltaic panel are always kept in a fit state, making the cleaning more thorough and greatly improving the cleaning effect.

[0078] Those skilled in the art will easily conceive of other implementation schemes of the present application after considering the specification and practicing the technical solutions disclosed herein.

[0079] This application is intended to cover any modifications, uses or adaptations of the present application, which follow the general principles of the present application and include common knowledge or customary technical means in the technical field that are not disclosed in the present application.
