Description

Technical Field

[0001] This utility model relates to the field of solar panel cleaning technology, specifically to a solar panel cleaning device and a solar panel assembly. Background Technology

[0002] Solar panel modules are power generation devices that produce direct current (DC) electricity when exposed to sunlight. Because they operate outdoors for extended periods, their surfaces accumulate a significant amount of dust and impurities. The presence of dust and impurities severely hinders the absorption of solar energy, leading to reduced power generation efficiency. Therefore, it is necessary to clean the solar panels to ensure their surface cleanliness and, consequently, their power generation efficiency.

[0003] There are two existing cleaning methods: manual cleaning and semi-automatic or automated cleaning using cleaning machines. Manual cleaning with tools involves a significant amount of labor. Existing cleaning machines also consume a considerable amount of electricity to clean solar panels. Therefore, both manual and machine cleaning rely on periodic cleaning, meaning the solar panels are cleaned at regular intervals. This ensures that the cleaning cost is less than the increased power generation revenue from cleaning the solar panels. However, during these intervals, dust and impurities gradually accumulate on the surface of the solar panels. The longer the interval, the more difficult it is to remove the accumulated dust and impurities, and the power generation efficiency of the solar panels gradually decreases, making it impossible to guarantee that the power generation efficiency of the solar panels will remain consistently high. Since solar panels have a limited lifespan, to fully utilize their power generation function within their lifespan, it is necessary to ensure that the solar panels maintain a high power generation efficiency and avoid periods of low efficiency.

[0004] For example, patents with authorization announcement number CN 222423614 U and utility model name "A Solar Photovoltaic Panel Cleaning Device," and patents with authorization announcement number CN 222519238 U and utility model name "Photovoltaic Panel Cleaning Robot and Photovoltaic Power Generation Device," both require significant energy consumption and have high energy efficiency when cleaning solar panels. Firstly, a generator with high power output is needed to drive the process; secondly, cleaning the solar panels consumes a considerable amount of energy. Therefore, regular cleaning is often used.

[0005] Therefore, those skilled in the art urgently need to develop a solar panel cleaning device that can clean solar panels at short intervals, thereby ensuring that the solar panels always maintain high power generation efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a solar panel cleaning device and solar panel assembly that consumes less electricity and has lower power efficiency. It can clean the solar panel at shorter intervals, thus ensuring a high level of cleanliness on the solar panel surface and keeping the solar panel at a consistently high power generation efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A solar panel cleaning device, comprising:

[0009] A mobile device, the mobile device including a movable element movable along an extension direction of the high-end side of the solar panel;

[0010] A suspension mechanism, comprising a wheel disposed on the movable member and a connecting belt wound around the wheel, wherein the wheel rotates and drives the connecting belt to move synchronously.

[0011] At least two scraping devices, each of which is connected to one end of the connecting strip and maintains balance based on its own weight;

[0012] A drive mechanism for driving the moving part to move and the rotating wheel to rotate;

[0014] Optionally, the driving energy of the driving mechanism of the mobile device is electrical energy, and the mobile component is provided with a solar panel for providing electrical energy to the driving mechanism;

[0015] The solar panel cleaning device also includes a first cleaning mechanism disposed on the high-end side of the solar panel;

[0016] When the moving part moves past the first cleaning mechanism, the first cleaning mechanism comes into contact with the power-generating solar panel to clean the power-generating solar panel.

[0017] Optionally, the mobile device includes a first body, which is the moving component, and a first traveling wheel that moves along the high end of the solar panel is provided on the first body; the driving mechanism includes a first motor and a second motor provided on the first body, the first motor being drivenly connected to the first traveling wheel, and the second motor being drivenly connected to the rotating wheel.

[0018] Optionally, the mobile device includes a first body, which is the moving component. The first body is provided with a power-generating solar panel and a first traveling wheel that moves along the high end of the solar panel. The rotating wheel is connected to the first traveling wheel through a first transmission mechanism, which has at least two transmission modes: co-directional transmission and reverse transmission. The driving mechanism includes a first motor mounted on the first body, which is connected to the first traveling wheel or the rotating wheel. The power-generating solar panel is connected to the first motor.

[0019] Optionally, the first traveling wheel is provided in three sets, and the three sets of the first traveling wheel roll on the first, second and third surfaces of the high-end side of the solar panel respectively, and at least one of the first traveling wheels is connected to the first motor for transmission.

[0020] Optionally, the bottom of the scraping device is provided with auxiliary wheels or a fine brush.

[0021] Optionally, the scraping device includes a second body, the bottom of which is provided with a first groove, and a plurality of scrapers are provided in the first groove at intervals, wherein the height difference between the lowest surface of the scraper and the lowest surface of the side wall of the first groove is less than or equal to a first preset distance.

[0022] Optionally, each scraper includes a first scraper and a second scraper, the ends of the first scraper and the second scraper are connected and form a first preset angle, the first preset angle being greater than 10 degrees and less than 170 degrees.

[0023] Optionally, the external shape of the scraping device is streamlined; and / or,

[0024] The mobile device has a streamlined external shape.

[0025] This utility model also provides a solar panel assembly, including a tilted solar panel, wherein the solar panel is provided with any of the solar panel cleaning devices described above.

[0026] In this invention, a moving device is installed, and a suspension mechanism is mounted on the moving part of the device. The suspension mechanism includes a wheel and a connecting belt, with a scraping device connected to each end of the connecting belt. This cancels out the downward component of the gravity of the two scraping devices on the solar panel. During the cleaning process, only the moving device needs power and the scraping resistance of the scraping devices needs to be overcome. Since the required energy power is low, a small amount of energy is sufficient to meet its energy needs, and an additional power-generating solar panel can be used as the energy source. Furthermore, because the total energy consumed is much less than the increased power generation of the solar panel due to cleaning, the solar panel can be cleaned at shorter intervals, ensuring a high level of cleanliness on the surface and maintaining high power generation efficiency.

Detailed Implementation

[0042] See below Figure 1-14 This utility model is described below. See also: Figure 1 and Figure 7When laying the solar panel 5, the solar panel 5 is laid on the fixing device 6. The fixing device 6 may include a support leg 61, and a fixing frame 62 is connected to the support leg 61. The solar panel 5 is set on the fixing frame 62 at an inclined position in the longitudinal direction. The higher side of the solar panel 5 is called the high-end side 51, and the lower side is called the low-end side 52. Both the high-end side 51 and the low-end side 52 extend laterally. The solar panel cleaning device provided by this utility model includes a moving device 1. The moving device 1 includes a moving part, which is set at the high-end side 51 of the solar panel 5 and can move along the lateral direction of the solar panel 5, that is, the extension direction of the high-end side 51. A suspension mechanism 2 is provided on the moving part. The suspension mechanism 2 includes a rotating wheel 21, and a connecting belt 23 is suspended on the rotating wheel 21. When the rotating wheel 21 rotates, it drives the connecting belt 23 to move synchronously. A scraping device 3 is connected to each end of the connecting belt 23. The two scraping devices 3 are located on the solar panel 5. In this way, the two scraping devices 3 can maintain balance based on their own weight under the pull of the connecting belt 23. In other words, under the combined forces of the tension provided by the connecting belt 23, the weight of the scraping device 3 itself, and the support force of the solar panel 5, the two scraping devices 3 can remain stationary on the inclined solar panel 5. The scraping devices 3 are in close contact with the solar panel 5 so that they scrape the solar panel 5 during movement. A drive mechanism is also included, which drives the moving parts to move and the rotating wheel 21 to rotate. The rotating wheel 21 drives the connecting belt 23 to rotate synchronously. Under the traction of the connecting belt 23, the two scraping devices 3 move in opposite directions on the solar panel 5, scraping the solar panel 5. Here, "opposite directions" refers to the opposite directions of the longitudinal velocity components of the two scraping devices 3 on the solar panel 5; that is, one scraping device 3 moves upward along the inclined direction of the solar panel 5, while the other scraping device 3 moves downward along the inclined direction of the solar panel 5. This ensures that the components of gravity of the two scraping devices 3 along the plane of the solar panel 5 are canceled out during their movement. Thus, during the cleaning process, there is no need to overcome the gravitational components of the two scraping devices 3 to do work; it is only necessary to overcome the frictional force to move the scraping devices 3.

[0043] The specific working process is as follows: The drive mechanism drives the moving part to reciprocate along the extension direction of the high-end side 51, moving from one end to the other, and then turning back, repeating this process. Simultaneously with the reciprocating motion of the moving part, the drive mechanism drives the rotating wheel 21 to rotate. The rotating wheel 21 drives the connecting belt 23 to move. Under the pull of the connecting belt 23, the two scraping devices 3 move up and down. When one scraping device 3 moves to the high-end side 51, the other scraping device 3 has just moved to the low-end side 52. Then, the drive mechanism drives the rotating wheel 21 to reverse, causing the scraping device 3 on the high-end side to move downwards and the scraping device 3 on the low-end side to move upwards, repeating this process. A position detection device can be installed to detect the positions of the moving device 1 and the scraping device 3, and a controller can be used to control the direction change of the moving device 1 and the rotating wheel 21. That is, when the moving device 1 is detected to have moved to the left or right limit position of the solar panel 5, the moving device 1 is controlled to move in the opposite direction. When the scraping device 3 is detected to have moved to the upper or lower limit position of the solar panel 5, the rotating wheel 21 is controlled to reverse direction, so that the scraping device 3 moves in the opposite direction. The position detection device and controller can be existing position detection devices and controllers.

[0044] This allows the solar panel cleaning device to clean solar panels 5 by providing only the moving power for the moving component and the moving power for the scraping device 3. Because the scraping device 3 is small and lightweight, the moving power required for the moving component to move itself, the scraping device 3, and the suspension mechanism 2 is also small. Furthermore, as mentioned above, the gravitational components of the two scraping devices 3 are canceled out, requiring only the overcoming of scraping resistance, thus requiring less moving power. Consequently, the rotational power required for the rotating wheel 21 is also less. Therefore, the total energy consumed by the solar panel cleaning device is low, and the power consumption is also low. The solar panel cleaning device can use an additional power-generating solar panel 15 as its power source. The power generation efficiency of this solar panel 15 is greater than the power consumption efficiency of the solar panel cleaning device, and the electricity generated by the solar panel 15 can promptly meet the power consumption needs of the solar panel cleaning device. During sunny days, the solar panel cleaning device can continuously clean the solar panels. If a high-power solar panel is used and additional batteries are added, excess electrical energy can be stored in the batteries. The stored energy can even power the solar panel cleaning device at night. In this way, the solar panel cleaning device can clean the solar panel at short intervals (cleaning during the day and intermittently at night) or continuously, thereby maintaining a high level of cleanliness on the surface of the solar panel 5 and ensuring that the solar panel 5 always operates at a high power generation efficiency.

[0045] The moving device 1 can be a ball screw structure, a gear rack structure, or a linear module, etc. In this case, the moving part can be a moving block in these structures, and the suspension mechanism 2 can be set on the moving block. The moving device 1 can also be an independent walking mechanism. The moving device 1 can include a first body 11, and the first body 11 or the moving device 1 itself is the moving part. The first body 11 can be equipped with a first walking wheel 12, which drives the entire moving device 1 to move along the high-end side 51 of the solar panel 5.

[0046] The pulley 21 can be a synchronous pulley, and the connecting belt 23 can be a synchronous belt; or the pulley 21 can be a V-shaped pulley, and the connecting belt 23 can be a V-shaped belt, with the V-shaped belt driving the V-shaped pulley to rotate synchronously through friction; or the pulley 21 can be a sprocket, and the connecting belt 23 can be a chain. Of course, other structures that make the pulley 21 and the connecting belt 23 rotate synchronously can also be used.

[0047] Optionally, the driving energy of the driving mechanism of the mobile device 1 is electrical energy, and a power-generating solar panel 15 is provided on the mobile component to provide power to the driving mechanism. The solar panel cleaning device also includes a first cleaning mechanism 4 disposed on the high-end side 51 of the solar panel 5; when the mobile component moves past the first cleaning mechanism 4, the first cleaning mechanism 4 contacts the power-generating solar panel 15 to clean the power-generating solar panel 15. Specifically, see Figure 2 , Figure 3 and Figure 10 When the moving part is the first body 11, the power-generating solar panel 15 can be mounted on the first body 11. (See also...) Figure 2 The solar panel cleaning device also includes a first cleaning mechanism 4 disposed on the high-end side 51 of the solar panel 5; when the moving part moves past the first cleaning mechanism 4, the first cleaning mechanism 4 contacts the power-generating solar panel 15 to clean the power-generating solar panel 15. The power-generating solar panel 15 can be a traditional solar panel or a thin-film solar panel.

[0048] The first cleaning mechanism 4 may include a first fixed rod 42 and a rotatable first roller brush 41. When the moving part passes through the first cleaning mechanism 4, the solar panel 15 comes into contact with the first roller brush 41, and the first roller brush 41 rotates passively to clean the solar panel 15. This ensures the cleanliness of the solar panel 15, thereby ensuring that the solar panel 15 generates electricity with high power generation efficiency.

[0049] The drive mechanisms used to move the movable component and rotate the wheel 21 can be either two or one. When there are two drive mechanisms, one can be provided for each of the movable component and the wheel 21. When there is only one drive mechanism, two transmission mechanisms can be provided to connect the drive mechanism to the movable component and the wheel 21 respectively; alternatively, the drive mechanism can be connected to one of them, and then the movable component and the wheel 21 can be connected through the first transmission mechanism. These will be described in detail below:

[0050] For cases with two drive mechanisms: see Figure 2-4 and Figure 12-14 The mobile device 1 includes a first body 11, which is the moving component. The first body 11 is equipped with first wheels 12 that move along the high-end side 51 of the solar panel 5. There may be one or more first wheels 12. The driving mechanism includes a first motor 13 and a second motor 22 mounted on the first body 11. The first motor 13 is connected to at least one first wheel 12. There may be one or more rotating wheels 21, and the second motor 22 is connected to at least one rotating wheel 21.

[0051] In this way, the movement of the first body 11 and the rotation of the wheel 21 are independent of each other and do not affect each other. This ensures that the lateral movement speed of the moving parts does not affect the vertical movement speed of the two scraping devices 3. This makes it easier to adjust the actual movement trajectory of the scraping devices 3, so that the scraping devices 3 can cover the entire solar panel 5 as comprehensively as possible without any missed areas.

[0052] In the case where there is only one drive mechanism: the mobile device 1 includes a first body 11, which is a moving part. The first body 11 is provided with a first traveling wheel 12 that moves along the high end side 51 of the solar panel 5. The rotating wheel 21 is connected to the first traveling wheel 12 through a first transmission mechanism. The first transmission mechanism has at least two transmission modes: same-direction transmission and reverse transmission. In addition, the first transmission mechanism can also have a clutch mode, that is, one does not drive the other to move. The drive mechanism includes a first motor 13 provided on the first body 11. The first motor 13 is connected to the first traveling wheel 12 or the rotating wheel 21 through a transmission connection. The power generating solar panel 15 is connected to the first motor 13.

[0053] The first transmission mechanism can be a transmission mechanism based on existing technology. See also... Figure 1 and Figure 4Taking the first motor and the first traveling wheel 12 as a transmission connection, and the first traveling wheel 12 and the rotating wheel 21 as a connection through the first transmission mechanism, the movement principle is introduced as follows: When the first motor 13 drives the first traveling wheel 12 to move from left to right, the first traveling wheel 12 rotates clockwise. The first transmission mechanism is adjusted to the same-direction transmission mode, and the rotating wheel 21 also rotates clockwise. The left scraping device 3 moves upward while the right scraping device 3 moves downward to scrape the solar panel 5. When the left scraping device 3 moves upward to the highest side, the right scraping device 3 moves to the lowest side. At this time, the first transmission mechanism is adjusted to the reverse transmission mode, and the rotating wheel 21 rotates counterclockwise, causing the left scraping device 3 to move downward while the right scraping device 3 moves upward to scrape the solar panel 5. The same principle applies when the moving device 1 moves from right to left; only the transmission direction of the first transmission mechanism needs to be set.

[0054] Optionally, in actual installation, a limiting structure is required to prevent the moving device 1 from tipping over from the high-end side 51, thus preventing the moving device 1 from detaching from the high-end side 51. Specifically, a groove can be provided on the high-end side 51, within which the first traveling wheel 12 travels; alternatively, an annular groove can be provided on the first traveling wheel 12, which mates with the high-end side 51. A preferred structure is as follows: (See...) Figures 2-3 , Figures 10-14 The first traveling wheel 12 can be provided in three sets. The three sets of first traveling wheels 12 roll on the first surface 511, the second surface 512 and the third surface 513 of the high-end side 51 of the solar panel 5, respectively. At least one first traveling wheel 12 is connected to the first motor 13 for transmission.

[0055] Since the three sets of first traveling wheels 12 of the mobile device 1 are respectively located on the first surface 511, the second surface 512, and the third surface 513 of the high-end side 51 of the solar panel 5, the mobile device 1 can be prevented from detaching from the high-end side 51. The first motor 13 is drivenly connected to at least one of the first traveling wheels 12, thereby driving the mobile device 1 to move along the high-end side 51. The first traveling wheel 12 driven by the first motor 13 rotates actively, while the other first traveling wheels 12 rotate passively and form rolling friction with the first surface 511, the second surface 512, and the third surface 513, which can reduce the moving resistance of the mobile device 1.

[0056] Optionally, see Figure 9The bottom of the scraping device 3 can be equipped with auxiliary traveling wheels 34 or fine brushes. The auxiliary traveling wheels 34 or fine brushes are used to assist the lateral movement of the scraping device 3, and can be positioned at the four corners. Adding auxiliary traveling wheels 34 or fine brushes increases the mobility of the scraping device 3. The auxiliary traveling wheels 34 can be omnidirectional wheels, preferably bullseye wheels. Since the scraping device 3 needs to move left and right under the drive of the moving device 1 while moving up and down, setting the auxiliary traveling wheels 34 as omnidirectional wheels facilitates the mobility of the scraping device 3.

[0057] Optionally, see Figure 5 and Figure 6 The scraping device 3 includes a second body 31. A first groove 33 is provided at the bottom of the second body 31. Several spaced-apart scrapers 32 are arranged within the first groove 33. The height difference between the lowest surface of the scraper 32 and the lowest surface of the sidewall of the first groove 33 is less than or equal to a first preset distance, which is specifically set as needed. The purpose is to ensure that the lowest surface of the sidewall of the first groove 33 is slightly higher than the lowest surface of the scraper 32, so that while the scraper 32 can scrape the solar panel 5, the gap between the lowest surface of the sidewall of the first groove 33 and the solar panel 5 is as small as possible, thus preventing wind from blowing into or excessively into the bottom of the second body 31 and overturning the scraping device 3.

[0058] See Figure 6 and Figure 9 Each scraper 32 includes a first scraper 321 and a second scraper 322. The ends of the first scraper 321 and the second scraper 322 are connected and form a first preset angle, which is greater than 10 degrees and less than 170 degrees.

[0059] Optionally, see Figure 5 and Figure 8 The external shape of the scraping device 3 is streamlined.

[0060] In this way, wind resistance can be further reduced, effectively preventing the wind from blowing the scraper device 3 over.

[0061] See Figure 10 The external shape of the mobile device 1 can be streamlined. Preferably, it is streamlined in the lateral direction. In this way, the wind resistance of the mobile device 1 can be further reduced, and the movement resistance can be reduced.

[0062] This utility model also provides a solar panel assembly, including a tilted solar panel, and the solar panel assembly is provided with any of the solar panel cleaning devices described above.

[0063] The following describes a preferred embodiment:

[0064] When laying the solar panel 5, the solar panel 5 is laid on the fixing device 6. The fixing device 6 may include a support leg 61, and a fixing frame 62 is connected to the support leg 61. The solar panel 5 is set on the fixing frame 62 at an inclined position in the longitudinal direction. The solar panel cleaning device includes a moving device 1, which includes a first body 11. The first body 11 is streamlined. See [reference needed]. Figure 10-14 The first body 11 is provided with a concave groove, and a set of first traveling wheels 12 are respectively provided on the three sides of the concave groove. Each set of first traveling wheels 12 can have one or more. A first motor 13 is provided inside the first body 11, and one of the first traveling wheels 12 is drivenly connected to the first motor 13. The concave groove is adapted to the high-end side 51, and the three sets of first traveling wheels 12 roll on the first side 511, the second side 512, and the third side 513 of the high-end side 51, respectively. A suspension mechanism 2 is provided inside the first body 11. The suspension mechanism 2 includes three rotating wheels 21, a second motor 22, and a connecting belt 23. The middle rotating wheel 21 is drivenly connected to the second motor 22, and the connecting belt 23 is wound around the three rotating wheels 21. The two ends of the connecting belt 23 pass through the through holes of the first body 11. A thin-film solar panel 15 is provided on the upper surface of the first body 11, and the solar panel 15 can directly power the first motor 13 and the second motor 22. Each end of the connecting belt 23 is connected to a scraping device 3. The scraping device 3 includes a second body 31, which is streamlined. Several spaced scraper blades 32 are provided at the bottom of the second body 31. Four auxiliary wheels 34, preferably bullseye wheels, are also provided at the four corners of the bottom of the second body 31. The second body 31 is also equipped with a position detector to detect whether the scraping device 3 has moved to the upper or lower limit position. A controller and a position detector are provided on the first body 11. The position detector is used to detect whether the moving device 1 has moved to the left or right limit position. When the scraping device 3 is detected to have moved to the upper or lower limit position, the controller controls the second motor 22 to drive the rotating wheel 21 in reverse. When the moving device 1 is detected to have moved to the left or right limit position, the controller controls the first motor 13 to drive the first traveling wheel 12 in reverse, thereby causing the moving device 1 to move in the opposite direction. The high-end side 51 of the solar panel 5 is also provided with a first cleaning mechanism 4. The first cleaning mechanism 4 includes a first fixing rod 42, on which a first roller brush 41 that can roll is provided. When the moving device 1 passes the first cleaning mechanism 4, the power-generating solar panel 15 comes into contact with the first roller brush 41, and the power-generating solar panel 15 is cleaned.

[0065] The above embodiments are merely illustrative of the present invention and not limiting. Under the concept of the present invention, technical solutions without substantial changes are still within the protection scope of the present invention.
