Description

Technical Field

[0001] The present invention relates to the technical field of solar panel cleaning, and particularly to a solar panel cleaning device and a solar panel assembly. Background Art

[0002] A solar panel assembly is a power generation device that generates direct current when exposed to sunlight. Since it works outdoors for a long time, its surface will be contaminated with a lot of dust and impurities. The presence of dust and impurities will seriously affect the absorption of solar energy by the solar panel, resulting in a low power generation efficiency of the solar panel. Therefore, it is necessary to clean the solar panel to ensure the cleanliness of the solar panel surface and thus ensure the power generation efficiency of the solar panel.

[0003] There are two existing cleaning methods. One is manual cleaning, and the other is semi-automatic or automatic cleaning using a cleaning machine. Manually using tools to clean and scrub requires a large amount of labor for one cleaning. The existing cleaning machines also consume a large amount of electricity for cleaning a solar panel once. Therefore, whether it is manual cleaning or machine cleaning, a regular cleaning method is adopted, that is, cleaning the solar panel once every period of time. In order to ensure that the cleaning cost is less than the increased power generation income due to cleaning the solar panel. However, during these intervals, the dust and impurities on the solar panel surface gradually accumulate. The longer the time interval, the more difficult it is to clean the accumulated dust and impurities, and the power generation efficiency of the solar panel also gradually decreases, and it is impossible to ensure that the power generation efficiency of the solar panel always remains at a high level. Since the solar panel has a certain service life, if you want to fully utilize its power generation function within its service life, it is necessary to ensure that the solar panel always maintains a high power generation efficiency and avoid the intervals with low power generation efficiency.

[0004] For example, in the patent with the authorization announcement number CN 222423614 U and the utility model name of a solar photovoltaic panel cleaning device, as well as the patent with the authorization announcement number CN 222519238 U and the utility model name of a photovoltaic panel cleaning robot and a photovoltaic power generation device, the energy consumption and energy consumption efficiency required for cleaning the solar panel are relatively large. First, a generator with a relatively large power generation capacity is required for driving, and second, a large amount of energy is consumed for cleaning the solar panel. Therefore, a regular cleaning method is mostly adopted for cleaning.

[0005] Therefore, those skilled in the art urgently need to make a solar panel cleaning device that can clean the solar panel at a smaller interval, so as to keep the solar panel always maintaining a high power generation efficiency. Summary of the Invention

[0006] The object of the present invention is to provide a solar panel cleaning device and a solar panel assembly, which consume less electric energy and have a lower power consumption efficiency. The solar panel can be cleaned at a relatively short time interval, thereby ensuring a high cleanliness of the surface of the solar panel and keeping the solar panel in a state of high power generation efficiency all the time.

[0010] Optionally, the mobile device includes a first body which serves as the moving member. A power generation solar panel and a first walking wheel that moves along the high-end side of the solar panel are provided on the first body.

The driving mechanism includes a first motor provided on the first body, the first motor is in transmission connection with the first walking wheel or the runner, and the power generation solar panel is connected to the first motor.

[0011] Optionally, three groups of the first walking wheels are provided. The three groups of the first walking wheels roll on the first surface, the second surface, and the third surface of the high-end side of the solar panel respectively, and at least one of the first walking wheels is in transmission connection with the first motor.

[0012] Optionally, auxiliary walking wheels or fine brushes are provided at the bottom of the scraping device.

[0014] Optionally, each scraping plate includes a first scraping plate and a second scraping plate. The ends of the first scraping plate and the second scraping plate are connected and form a first preset angle, and the first preset angle is greater than 10 degrees and less than 170 degrees.

During the cleaning process of the solar panel, only the driving force for moving the moving device and the scraping resistance of the scraping device need to be overcome. Since the required energy power consumption is relatively low, a relatively small power energy source can meet its energy consumption requirements, and an additional power generation solar panel can be used as the energy source. And because the total energy consumption required is relatively small, far less than the increased power generation of the solar panel due to cleaning, the solar panel can be cleaned at a relatively small time interval, thereby ensuring a high cleanliness of the solar panel surface and keeping the solar panel at a high power generation efficiency all the time.

Detailed implementation manners

[0020] The following refers to Figure 1-14 describe the present invention. Refer to Figure 1 and Figure 7, when laying the solar panel 5, the solar panel 5 is laid on the fixing device 6. The fixing device 6 may include legs 61, and a fixing frame 62 is connected to the legs 61. The solar panel 5 is arranged in an inclined posture longitudinally on the fixing frame 62. 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 transversely. The solar panel cleaning device provided by the present invention includes a moving device 1. The moving device 1 includes a moving member arranged at the high-end side 51 of the solar panel 5 and capable of moving along the transverse direction of the solar panel 5, that is, the extending direction of the high-end side 51. A suspension mechanism 2 is arranged on the moving member. The suspension mechanism 2 includes a runner 21, and a connecting belt 23 is suspended on the runner 21. When the runner 21 rotates, it drives the connecting belt 23 to move synchronously. Both ends of the connecting belt 23 are respectively connected to a scraping device 3, and 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 gravity under the traction of the connecting belt 23. That is, under the action of the pulling force provided by the connecting belt 23, the gravity of the scraping device 3 itself, and the supporting force of the solar panel 5, the two scraping devices 3 can be stationary on the inclined solar panel 5. The scraping device 3 is in close contact with the solar panel 5 so that the scraping device 3 can scrape the solar panel 5 when moving. It also includes a driving mechanism for driving the moving member to move and driving the runner 21 to rotate. The runner 21 drives the connecting belt 23 to rotate synchronously. The two scraping devices 3 move in opposite directions on the solar panel 5 under the traction of the connecting belt 23 to scrape the solar panel 5. The opposite directions here refer to the directions of the longitudinal component velocities of the two scraping devices 3 on the solar panel 5 being opposite, that is, one scraping device 3 moves upward along the inclined direction of the solar panel 5, and the other scraping device 3 moves downward along the inclined direction of the solar panel 5, so that during the movement of the two scraping devices 3, the components of their gravity along the plane direction of the solar panel 5 are offset. In this way, during the cleaning process, there is no need to overcome the work done by the gravity component of the two scraping devices 3, and only the friction needs to be overcome to move the scraping device 3.

[0021] The specific working process is as follows: The driving mechanism drives the moving member to reciprocate along the extension direction of the high-end side 51, moving from one end to the other end, and then turning back, repeating this process. While the moving member is reciprocating, the driving mechanism drives the rotating wheel 21 to rotate. The rotating wheel 21 drives the connecting belt 23 to move. Under the pulling 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 just moves to the low-end side 52. Then the driving mechanism drives the rotating wheel 21 to reverse, so that the scraping device 3 located on the high-end side moves downward, and the scraping device 3 located on the low-end side moves upward, repeating this process. Among them, the position detection device can be set to detect the positions of the moving device 1 and the scraping device 3, and the controller is used to control the direction change of the moving device 1 and the rotating wheel 21. That is, when it is detected that the moving device 1 moves to the left limit position or the right limit position of the solar panel 5, the moving device 1 is controlled to move in the opposite direction. When it is detected that the scraping device 3 moves to the upper limit position or the lower limit position of the solar panel 5, the rotating wheel 21 is controlled to change its direction, so that the scraping device 3 moves in the opposite direction. Among them, the position detection device and the controller can adopt the position detection device and the controller in the existing technology.

[0022] This enables the solar panel cleaning device to only provide the moving power of the moving member and the moving power of the scraping device 3 during the cleaning process of the solar panel 5. Since the volume of the scraping device 3 is small and the weight is light, the moving power required for the moving member to drive itself, the scraping device 3 and the suspension mechanism 2 to move is relatively small. In addition, as described above, the gravity component forces of the two scraping devices 3 are offset, and only the scraping resistance needs to be overcome to move, so the required moving power is also small, and the rotational power required for the rotating wheel 21 is also small. Therefore, the total energy consumed by the solar panel cleaning device is small and the power of the consumed energy is low. The solar panel cleaning device can use the additionally provided power generation solar panel 15 as the power supply source. The power generation efficiency of the power generation solar panel 15 is greater than the power consumption efficiency of the solar panel cleaning device, and the electricity generated by the power generation solar panel 15 can timely meet the power consumption demand of the solar panel cleaning device. During the day with sunlight, the solar panel cleaning device can continuously clean the solar panel. If a power generation solar panel with a larger power generation capacity is used and a battery is additionally added, the excess electric energy will be stored in the battery, and the accumulated electric energy can even be used by the solar panel cleaning device at night. In this way, the solar panel cleaning device can clean the solar panel at a smaller time interval (cleaning during the day and intermittent at night) or continuously, thereby keeping the surface of the solar panel 5 highly clean and enabling the solar panel 5 to always be at a high power generation efficiency.

[0023] Among them, the moving device 1 can be a ball screw structure, a rack and pinion structure, a linear module, etc. At this time, the moving part can be the moving block in these structures, and the suspension mechanism 2 can be arranged 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. The first body 11 or the moving device 1 itself is the moving part. A first walking wheel 12 can be arranged on the first body 11, and the first walking wheel 12 drives the entire moving device 1 to move along the high-end side 51 of the solar panel 5.

[0024] The runner 21 can be a synchronous pulley, and the connecting belt 23 is a synchronous belt; or the runner 21 is a V-shaped pulley, and the connecting belt 23 is a V-shaped belt, and the V-shaped belt drives the V-shaped pulley to rotate synchronously through friction; or the runner 21 is a sprocket, and the connecting belt 23 is a chain. Of course, it can also be other structures that make the runner 21 and the connecting belt 23 rotate synchronously.

[0025] Optionally, the driving energy source of the driving mechanism of the moving device 1 is electric energy, and a power generation solar panel 15 for supplying electric energy to the driving mechanism is arranged on the moving part. The solar panel cleaning device further includes a first cleaning mechanism 4 arranged 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 generation solar panel 15 to clean the power generation solar panel 15. Specifically, refer to Figure 2 、 Figure 3 and Figure 10 When the moving part is the first body 11, the power generation solar panel 15 can be arranged on the first body 11. Refer to Figure 2 The solar panel cleaning device further includes a first cleaning mechanism 4 arranged 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 generation solar panel 15 to clean the power generation solar panel 15. The power generation solar panel 15 can be a traditional solar panel or a thin-film solar panel.

[0026] Among them, the first cleaning mechanism 4 can include a first fixed rod 42 and a rotatable first brush 41. When the moving part passes by the first cleaning mechanism 4, the power generation solar panel 15 contacts the first brush 41, and the first brush 41 is driven to rotate passively to clean the power generation solar panel 15. To ensure the cleanliness of the power generation solar panel 15, and thus ensure that the power generation solar panel 15 generates electricity with a high power generation efficiency.

[0027] The drive mechanism for driving the movement of the moving part and the rotation of the runner 21 can be two or one. When there are two drive mechanisms, one drive mechanism can be provided for the moving part and the runner 21 respectively. When there is one drive mechanism, two transmission mechanisms can be set so that the drive mechanism is respectively in transmission connection with the moving part and the runner 21; of course, the drive mechanism can also be in transmission connection with one of them, and then the moving part and the runner 21 form a transmission relationship through the first transmission mechanism. The following will be introduced respectively: The case where there are two drive mechanisms: Refer to Figure 2-4 and Figure 12-14 , the mobile device 1 includes a first body 11, the first body 11 is the moving part, and a first traveling wheel 12 for moving along the high-end side 51 of the solar panel 5 is arranged on the first body 11; one or more than two first traveling wheels 12 can be arranged. The drive mechanism includes a first motor 13 and a second motor 22 arranged on the first body 11, and the first motor 13 is in transmission connection with at least one first traveling wheel 12. One or more than two runners 21 can be arranged, and the second motor 22 is at least in transmission connection with one runner 21.

[0028] In this way, the movement of the first body 11 and the rotation of the runner 21 are independent of each other and do not affect each other. Thus, the lateral movement speed of the moving part and the up-and-down movement speed of the two scraping devices 3 do not affect each other. Thus, it is convenient to adjust the actual movement track of the scraping device 3 so that the scraping device 3 can cover the entire solar panel 5 as comprehensively as possible without any missed scraping areas.

[0029] The case where there is one drive mechanism: The mobile device 1 includes a first body 11, the first body 11 is the moving part, and a first traveling wheel 12 for moving along the high-end side 51 of the solar panel 5 is arranged on the first body 11; the runner 21 is connected to the first traveling wheel 12 through a first transmission mechanism, and the first transmission mechanism has at least two transmission modes: forward 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 arranged on the first body 11, the first motor 13 is in transmission connection with the first traveling wheel 12 or the runner 21, and the power generation solar panel 15 is connected to the first motor 13.

[0030] Among them, the first transmission mechanism can adopt a transmission mechanism in the prior art. Refer to Figure 1 and Figure 4, taking the example that the first motor is drivingly connected to the first traveling wheel 12, and the first traveling wheel 12 is connected to the runner 21 through the first transmission mechanism, the moving 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. Adjust the first transmission mechanism to the same-direction transmission mode, and the runner 21 also rotates clockwise. The scraping device 3 on the left moves upward while the scraping device 3 on the right moves downward to scrape the solar panel 5. When the scraping device 3 on the left moves upward to the highest side, the scraping device 3 on the right just moves to the lowest side. At this time, adjust the first transmission mechanism to the reverse transmission mode, and the runner 21 rotates counterclockwise, so that the scraping device 3 on the left moves downward while the scraping device 3 on the right moves upward to scrape the solar panel 5. When the moving device 1 moves from right to left, it is the same reason, and only the transmission direction of the first transmission mechanism needs to be set properly.

[0031] Optionally, in actual setting, a limiting structure is required to prevent the moving device 1 from tipping out from the high-end side 51, so as to prevent the moving device 1 from tipping over and disengaging from the high-end side 51. Specifically, a groove can be set on the high-end side 51, and the first traveling wheel 12 travels in the groove; or a ring groove can be set on the first traveling wheel 12, and the ring groove cooperates with the high-end side 51, etc. A relatively optimal structure is as follows: Refer to Figure 2-Figure 3 , Figure 10-Figure 14 , three groups of the first traveling wheels 12 can be provided. The three groups of the 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, and at least one first traveling wheel 12 is drivingly connected to the first motor 13.

[0032] Since the three groups of the first traveling wheels 12 of the moving 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 moving device 1 can be prevented from disengaging from the high-end side 51. The first motor 13 is drivingly connected to at least one first traveling wheel 12, so as to drive the moving device 1 to move along the high-end side 51. The first traveling wheel 12 drivingly connected to the first motor 13 rotates actively, and 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 moving device 1.

[0033] Optionally, refer to Figure 9, an auxiliary traveling wheel 34 or a fine brush may be provided at the bottom of the scraping device 3. The auxiliary traveling wheel 34 or the fine brush is used to assist the lateral movement of the scraping device 3, and the auxiliary traveling wheel 34 or the fine brush may be provided at the positions of the four corners. Adding the auxiliary traveling wheel 34 or the fine brush can increase the mobility of the scraping device 3. Among them, the auxiliary traveling wheel 34 may be a universal wheel, preferably a bull's eye wheel. 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 wheel 34 as a universal wheel facilitates the mobility of the scraping device 3.

[0034] Optionally, referring to 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, and a plurality of scraping plates 32 are provided at intervals in the first groove 33. The height difference between the lowest surface of the scraping plate 32 and the lowest surface of the side wall of the first groove 33 is less than or equal to a first preset distance, and the first preset distance is specifically set according to needs. The purpose is to make the lowest surface of the side wall of the first groove 33 slightly higher than the lowest surface of the scraping plate 32, so as to ensure that while the scraping plate 32 can scrape the solar panel 5, the gap between the lowest surface of the side wall of the first groove 33 and the solar panel 5 is as small as possible, so as to prevent the wind from blowing into or blowing into the bottom of the second body 31 more, and tipping over the scraping device 3.

[0035] Referring to Figure 6 and Figure 9 , each scraping plate 32 includes a first scraping plate 321 and a second scraping plate 322. The ends of the first scraping plate 321 and the second scraping plate 322 are connected and form a first preset angle, and the first preset angle is greater than 10 degrees and less than 170 degrees.

[0036] Optionally, referring to Figure 5 and Figure 8 , the external shape of the scraping device 3 is streamlined.

[0037] In this way, the wind resistance can be further reduced, and the wind can effectively prevent the scraping device 3 from being blown over.

[0038] Referring to Figure 10 , the external shape of the moving device 1 may be streamlined. Preferably, it is streamlined in the horizontal direction. In this way, the wind resistance of the moving device 1 can be further reduced, and the moving resistance can be reduced.

[0039] The present invention also provides a solar panel assembly, including an inclined solar panel, and any one of the above-described solar panel cleaning devices is provided on the solar panel assembly.

[0040] Hereinafter, a preferred embodiment will be introduced: When laying the solar panel 5, the solar panel 5 is laid on the fixing device 6. The fixing device 6 may include legs 61, and a fixing frame 62 is connected to the legs 61. The solar panel 5 is arranged in an inclined posture longitudinally on the fixing frame 62.

Refer to Figure 10-14 , a concave groove is provided on the first body 11. A set of first traveling wheels 12 are respectively provided at three surfaces of the concave groove. Each set of first traveling wheels 12 may have one or more than two. A first motor 13 is arranged inside the first body 11. One of the first traveling wheels 12 is in transmission connection with the first motor 13. The concave groove is adapted to the high-end side 51. The three sets of first traveling wheels 12 respectively roll on the first surface 511, the second surface 512, and the third surface 513 of the high-end side 51. A suspension mechanism 2 is arranged 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 in transmission connection with the second motor 22. The connecting belt 23 is wound around the three rotating wheels 21. Both ends of the connecting belt 23 pass through the through holes of the first body 11. A thin-film type power generation solar panel 15 is arranged on the upper surface of the first body 11. The power generation solar panel 15 can directly supply power to the first motor 13 and the second motor 22. A scraping device 3 is connected to each end of the connecting belt 23. The scraping device 3 includes a second body 31. The second body 31 is streamlined. A plurality of scraper plates 32 are arranged at intervals at the bottom of the second body 31. Four auxiliary traveling wheels 34 are further arranged at the four corners of the bottom of the second body 31. The auxiliary traveling wheels 34 are preferably bull's-eye wheels. The second body 31 is further provided with a position detector to detect whether the scraping device 3 moves to the upper limit position or the lower limit position. A controller and a position detector are arranged on the first body 11. The position detector is used to detect whether the moving device 1 moves to the left limit position or the right limit position. When it is detected that the scraping device 3 moves to the upper limit position or the lower limit position, the controller controls the second motor 22 to drive the rotating wheel 21 to reverse. When it is detected that the moving device 1 moves to the left limit position or the right limit position, the controller controls the first motor 13 to drive the first traveling wheels 12 to reverse, so as to make the moving device 1 move in the reverse direction. A first cleaning mechanism 4 is further arranged on the high-end side 51 of the solar panel 5. The first cleaning mechanism 4 includes a first fixing rod 42, and a first rolling brush 41 that can roll is arranged on the first fixing rod 42. When the moving device 1 passes through the first cleaning mechanism 4, the power generation solar panel 15 contacts the first rolling brush 41 to clean the power generation solar panel 15.
