Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panel cleaning, and particularly to a photovoltaic system with a cleaning device. Background Art

[0002] Since dust and snow on the photovoltaic panel will affect the photoelectric conversion efficiency of the photovoltaic panel, there are already various cleaning robots in the industry that can move freely on the photovoltaic panel and can regularly clean the surface of the photovoltaic panel to save labor.

[0003] A commonly used one in the industry is an orbital robot, which includes a vehicle body. Taking the photovoltaic panel array as an orbit, it can move horizontally along the photovoltaic panel array. During the movement, the surface of the panel array is cleaned by a rolling brush at the bottom of the robot, and the upper and lower ends of the robot can respectively move along the upper and lower frames of the photovoltaic panel array.

[0004] In the prior art, a distance sensor is usually set at the edge of the orbital robot to obtain the distance between the bottom of the robot and the photovoltaic panel in real time. When the robot moves to the edge of one end of the panel array, the robot adjusts the rotation direction of the wheels and moves in the reverse direction to avoid the robot falling off the panel. However, the rolling brush is usually set in the middle of the bottom of the vehicle body. When the vehicle body moves to one end of the panel array and starts to move in the reverse direction, there is still a certain gap between the rolling brush and the panel edge, resulting in some areas at the panel edge forming a cleaning dead angle.

[0005] Since the panel needs to be cleaned regularly, for example, once every five days for 1 hour each time, a photovoltaic panel can also be set on the top surface of the orbital robot, and the robot can be charged by solar energy during the idle time of the robot. After the robot stops working, it can stay on the photovoltaic panel array to be charged, so that the robot does not need to be frequently removed from the photovoltaic panel to replace the battery, thus saving manpower and material resources. However, if the orbital robot stays on the panel array for a long time in a non-cleaning state, it will inevitably block some photovoltaic panels, thereby reducing the power generation of the entire photovoltaic panel array. It is difficult to achieve both avoiding the removal of the robot and avoiding the reduction of power generation. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a photovoltaic system with a cleaning device to solve the technical problems that the cleaning robot of the photovoltaic panel in the prior art is prone to form cleaning dead angles at both ends of the panel array, and it is difficult to achieve both avoiding the removal of the robot and avoiding the reduction of power generation.

[0007] To solve the above problems, the present utility model provides a photovoltaic system with a cleaning device. The photovoltaic system with a cleaning device includes a photovoltaic panel array, two platforms, and a cleaning robot. The photovoltaic panel array extends along the horizontal direction. The two platforms are respectively installed at both ends of the photovoltaic panel array in its extending direction. The top surfaces of the two platforms are in the same plane as the top surface of the photovoltaic panel array. The cleaning robot can travel on the photovoltaic panel array and can travel to the top surfaces of the two platforms.

[0008] Further, the photovoltaic panel array includes: two or more photovoltaic panels arranged in an array; two or more first strip-shaped rods extending along the horizontal direction and fixed to the bottom surface of the photovoltaic panel; and at least one panel support, with a second strip-shaped rod provided at its top and fixedly connected to two or more first strip-shaped rods.

[0009] Further, each platform includes a rectangular frame, including two relatively arranged long side frames and two relatively arranged short side frames. One long side frame is fixedly connected to the edge of one end of the photovoltaic panel array.

[0010] Further, each platform includes a limiting member, fixedly connected to the top of a short side frame away from one end of the photovoltaic panel array, or fixedly connected to the top of a long side frame away from the photovoltaic panel array.

[0011] Further, each platform includes a first connecting rod, and the first connecting rod is fixedly connected to the bottoms of the two long side frames. One end of the first connecting rod extends to the bottom of a photovoltaic panel and is fixedly connected to a first strip-shaped rod.

[0012] Further, each platform includes a second connecting rod, and both ends of the second connecting rod are respectively fixedly connected to the middle parts of the two first long side frames.

[0013] Further, the cleaning robot includes: a vehicle body and wheels, and the wheels are provided at the bottom of the vehicle body. When the vehicle body travels on the platform, the wheels roll on the top surface of a short side frame.

[0014] Further, each platform includes a strip-shaped plate, and both ends of the strip-shaped plate are respectively fixed to the top or bottom of the two long side frames. The strip-shaped plate is provided with two or more through holes, and the arrangement direction of the through holes is the same as the extending direction of a short side frame.

[0015] Further, the cleaning robot includes: a vehicle body and a distance sensor, and the distance sensor is provided at the bottom of the vehicle body, and the distance sensor faces downward. When the vehicle body travels on the platform, each distance sensor can be located above a strip-shaped plate.

[0016] Further, the platform includes a cleaning bracket fixedly connected to the top of the rectangular frame. The cleaning bracket is provided with a strip brush and a strip scraper. The cleaning robot includes a vehicle body and a second photovoltaic panel disposed on the top surface of the vehicle body. When the vehicle body travels on the platform, the second photovoltaic panel is swept by the strip brush and scraped by the strip scraper.

[0017] Further, the cleaning bracket includes two vertical rods respectively fixedly connected to the upper end and the middle top surface of the long side frame away from the photovoltaic panel array, a bracket frame including a third long side frame and two third short side frames, two first traction ropes, one end of each first traction rope being connected to the top of a vertical rod and the other end being connected to one end of a third short side frame close to the photovoltaic panel array, and a second traction rope, the two ends of which are respectively fixedly connected to the middle parts of the two vertical rods.

[0018] Further, one end of each third short side frame is fixedly connected to the middle part of a vertical rod, and the other end extends towards the photovoltaic panel array, and the extending direction of the third short side frame is the same as that of the short side frame. The two ends of the third long side frame are respectively fixedly connected to the ends of the two third short side frames away from the vertical rod. The strip brush and the strip scraper are mounted on the third long side frame.

[0019] The advantages of the present utility model are as follows: a photovoltaic system with a cleaning device is provided. A platform is respectively arranged at both ends of the photovoltaic panel array, effectively expanding the traveling space of the robot in the horizontal direction, enabling part or all of the robot to travel outside the panel array, so as to ensure that the part of the panel array near the edge can also be swept by the roller brush of the robot, thus ensuring no dead angle in cleaning.

[0020] The first platform is a short rectangular frame. When the robot travels above the first platform, the robot can obtain feedback signals in real time through sensors, thereby determining that the robot travels to the edge of the photovoltaic panel array, and issuing an instruction to drive the robot to travel in the reverse direction, effectively preventing the robot from falling.

[0021] The second platform is a long rectangular frame. When the robot travels above the second platform, the robot can obtain feedback signals in real time through sensors, thereby calculating the traveling distance of the robot on the second platform. When the robot travels to the specified position, the robot automatically shuts down and stays on the second platform. The staff does not need to take the robot off the photovoltaic panel array, which can effectively save manpower. At the same time, the robot does not block the photovoltaic panel array, and the photovoltaic panel array can work normally without reducing the power generation. Description of the Drawings

[0045] As Figure 1 shown, this embodiment provides a photovoltaic system with a cleaning device. The photovoltaic system with a cleaning device includes a photovoltaic panel array 1, two platforms 2, 3, and a cleaning robot 4.

[0046] In this embodiment, the photovoltaic panel array 1 is an array structure formed by sequentially connecting multiple photovoltaic panels 10 of two rows with equal dimensions, and the photovoltaic panel array 1 extends horizontally to the left or right.

[0047] As Figure 2 shown, the photovoltaic panel array 1 further includes four first strip-shaped rods 11 extending along the horizontal direction and a panel support 12. The four mutually parallel first strip-shaped rods 11 are respectively fixed to the bottom surface of the photovoltaic panel 10; the bottom of the panel support 12 is fixed to the ground, and its top is provided with a second strip-shaped rod 13, which is vertically and fixedly connected to two or more first strip-shaped rods 11.

[0048] As Figure 1As shown in the figure, a first platform 2 is provided on the left side of the photovoltaic panel array 1, and a second platform 3 is provided on the right side of the photovoltaic panel array 1. The top surfaces of the two platforms 2 and 3 are on the same plane as the top surface of the photovoltaic panel array 1. The structures of the two platforms 2 and 3 are similar, but their widths in the extending direction of the photovoltaic panel array 1 are different. The width of one platform is less than the width of the robot, and the width of the other platform is greater than the width of the robot.

[0049] As Figure 3 shown, the first platform 2 includes a first rectangular frame, and the first rectangular frame includes two relatively arranged first long side frames 21, 22 and two relatively arranged first short side frames 23, 24; one first long side frame 21 is fixedly connected to the edge at the left end of the photovoltaic panel array 1.

[0050] The first platform 2 includes one or more limiting members 25, which are fixedly connected to the top of the first short side frame 23 away from the photovoltaic panel array 1. The limiting member 25 in this embodiment is a plate-like member similar to an L shape, which can be used to prevent the robot from sliding off the panel array.

[0051] In other embodiments, the limiting member 25 can also be fixedly connected to the top of the first long side frame 22 away from the photovoltaic panel array 1.

[0052] As Figure 4 shown, the first platform 2 further includes a first connecting rod 201 and a second connecting rod 202. The first connecting rod 201 is fixedly connected to the bottoms of the two first long side frames 21, 22 through fasteners; one end of the first connecting rod 201 extends to the bottom of a photovoltaic panel 10 and is fixedly connected to a first strip-shaped rod 11 through fasteners. The two ends of the second connecting rod 202 are respectively fixedly connected to the middle parts of the two first long side frames 21, 22 through fasteners.

[0053] As Figure 6 shown, the second platform 3 includes a second rectangular frame, and the second rectangular frame includes two relatively arranged second long side frames 31, 32 and two relatively arranged second short side frames 33, 34; one second long side frame 31 is fixedly connected to the edge at the right end of the photovoltaic panel array 1.

[0054] The second platform 3 includes one or more limiting members 35, which are fixedly connected to the top of the first short side frame 23 away from the photovoltaic panel array 1. The limiting member 35 in this embodiment is a columnar member, which can be used to prevent the robot from sliding off the panel array. In other embodiments, the limiting member 35 can also be fixedly connected to the top of the first short side frame 33 away from the photovoltaic panel array 1.

[0055] Similar to the first platform 2, the second platform 3 also includes two connecting rods. One connecting rod is fixedly connected to the bottoms of two second long side frames 31 and 32 through fasteners; one end of this connecting rod extends to the bottom of a photovoltaic panel 10 and is fixedly connected to a first strip-shaped rod 11 through fasteners. The two ends of the other connecting rod are respectively fixedly connected to the middle parts of two second long side frames 31 and 32, which will not be elaborated here.

[0056] The cleaning robot 4 is an orbital robot placed on the surface of the photovoltaic panel array 1, spanning the photovoltaic panel array 1 from top to bottom. Taking the photovoltaic panel array 1 as an orbit, it can travel horizontally along the photovoltaic panel array 1 and use the roller brush at the bottom of the robot to clean the surface of the panel array during travel.

[0057] The cleaning robot 4 includes a vehicle body 41. Wheels (not shown in the figure) are provided at the bottom of the vehicle body 41. When the vehicle body 41 travels on a platform 2 / 3, the wheels roll on the top surface of a short side frame 21 / 31. Further, second wheels (not shown in the figure) are respectively provided at the upper and lower ends of the vehicle body 41, which can respectively roll along the sides of the upper and lower frames of the photovoltaic panel array 1, so that the vehicle body 41 can travel on the inclined photovoltaic panel array 1. When the cleaning robot 4 travels, the vehicle body 41 can move along the horizontal direction, so that its own cleaning device can cover the entire photovoltaic panel array 1 during travel and can travel to the top surfaces of the first platform 2 and the second platform 3.

[0058] The first platform 2 is used to prevent the cleaning robot 4 from falling, and the second platform 3 is used to park the cleaning robot 4. When the cleaning robot 4 is idle, it is placed on the upper surface of the second platform 3 to avoid blocking the photovoltaic panel array 1. After the cleaning robot 4 is started, it travels from the second platform 3 to the first platform 2. After the front end of the cleaning robot 4 travels to the first platform 2, it can automatically adjust its traveling direction according to its position and then travel back to the second platform 3. After the cleaning robot 4 travels to the second platform 3, it stops moving, or turns again to move in the opposite direction.

[0059] As Figure 3-4 shown, the first platform 2 includes a first strip-shaped plate 26. The two ends of the first strip-shaped plate 26 are respectively fixed to the tops or bottoms of two first long side frames 21 and 22. The first strip-shaped plate 26 is provided with a plurality of through holes 261, which are arranged at intervals along the traveling direction of the cleaning robot 4, and the arrangement direction of the through holes 261 is the same as the extending direction of a short side frame.

[0060] As Figure 5As shown in the figure, the second platform 3 includes a second strip plate 36, and both ends of the second strip plate 36 are respectively fixed to the tops or bottoms of two second long side frames 31 and 32. The second strip plate 36 is provided with a plurality of through holes 361, which are arranged at intervals along the traveling direction of the cleaning robot 4. The arrangement direction of the through holes 261 is consistent with the extending direction of a short side frame, and the through hole 261 with the largest distance from the photovoltaic panel array 1 is a strip-shaped through hole.

[0061] The cleaning robot includes one or two distance sensors (not shown in the figure) provided at the bottom of the vehicle body 41. The distance sensors are ultrasonic sensors or infrared sensors facing downward; when the vehicle body 41 travels on a platform 2 / 3, each distance sensor can be located above a strip plate 26 / 36. During the traveling process of the vehicle body, the distance sensor can obtain the real-time distance between the sensor and the strip plate 26 / 36 below in real time. When the distance sensor is located above the strip plate 26 / 36, a feedback signal representing a short distance can be obtained. When the distance sensor is located above a through hole 261 / 361, an effective feedback signal cannot be obtained, or a feedback signal representing a long distance can be obtained. The control system of the robot judges the specific position of the robot on the platform according to the distance feedback signal collected in real time.

[0062] As Figure 3-5 shown in the figure, when the distance sensor passes through two square through holes 261 and is located above the first strip plate 26 again, the control system of the cleaning robot 4 judges that the cleaning robot 4 has traveled to the first platform 2, that is, the edge of the photovoltaic panel array 1 in the horizontal direction, according to the real-time feedback signal of the distance sensor, and thus controls the motor and wheels of the cleaning robot 4 to rotate in the reverse direction, so that the vehicle body travels in the reverse direction towards the second platform 3.

[0063] As Figure 6-7 shown in the figure, when the distance sensor passes through two square through holes 361 and the strip-shaped through hole 362 and is located above the second strip plate 36 again, the control system of the robot judges that the cleaning robot 4 has reached the designated position of the second platform 3 according to the real-time feedback signal of the distance sensor. At this time, the cleaning robot 4 has completed the cleaning of the photovoltaic panel array 1, and controls the cleaning robot 4 to automatically shut down, so that the cleaning robot 4 stays on the second platform 3.

[0064] As Figure 8 shown in the figure, the second platform 3 further includes a cleaning bracket 5, which is fixedly connected to the top of the second rectangular frame. The cleaning bracket 5 includes two vertical rods 51, a bracket frame 52, two first traction ropes 53 and a second traction rope 54, and further includes a strip-shaped brush 55 and a strip-shaped scraper 56.

[0065] Two vertical rods 51 are respectively fixedly connected to the top surface of the upper end and the middle part of the second long side frame 32 away from the photovoltaic panel array 1. The support frame 52 includes a third long side frame 521 and two third short side frames 522. One end of each third short side frame 522 is fixedly connected to the middle part of a vertical rod 51, and the other end extends towards the photovoltaic panel array 1. The extending direction of the third short side frame 522 is the same as that of the first short side frame 22. Both ends of the third long side frame 521 are respectively fixedly connected to the ends of the two third short side frames 522 away from the vertical rod 51.

[0066] One end of each first towing rope 53 is connected to the top of a vertical rod 51, and the other end is connected to one end of a third short side frame 522 close to the photovoltaic panel array 1. Both ends of the second towing rope 54 are respectively fixedly connected to the middle parts of the two vertical rods 51. The two towing ropes play a role in strengthening and reinforcing the cleaning bracket 5 to prevent the third short side frame 522 from deforming.

[0067] The cleaning robot 4 includes a second photovoltaic panel 42 arranged on the top surface of the vehicle body 41, which is used to convert solar energy into electric energy and store it in the battery of the robot when the cleaning robot 4 is idle. The strip brush 55 is installed at the bottom of the third long side frame 521 and extends downward; the strip scraper 56 is installed on the side wall of the third long side frame 521 and extends downward. When the vehicle body 41 travels on the second platform 3, the second photovoltaic panel 42 is swept by the strip brush 55 and scraped by the strip scraper 56, so that the second photovoltaic panel 42 can be cleaned.

[0068] As Figures 1 to 8 shown, this embodiment provides a photovoltaic system with a cleaning device. When the photovoltaic panel array 1 does not need to be cleaned, the cleaning robot 4 can stay on the second platform 3. At this time, the cleaning robot 4 will not block the photovoltaic panel array 1, avoiding the loss of the power generation efficiency of the photovoltaic panel array 1. At the same time, the user does not need to carry the cleaning robot 4 from other places to the surface of the photovoltaic panel array 1, or carry the cleaning robot 4 down from the photovoltaic panel surface, and only needs to directly start the cleaning robot 4.

[0069] After the user starts the cleaning robot 4, the cleaning robot 4 travels towards the first platform 2. When starting, each distance sensor can be arranged opposite to a second strip plate 36. When the cleaning robot 4 travels on the surface of the second platform 3, when each distance sensor is arranged opposite to the plate body of the second strip plate 36, the distance sensor will obtain a feedback signal representing a short distance. When each distance sensor is arranged opposite to a through hole 361, the distance sensor will not be able to obtain an effective feedback signal, or receive a feedback signal representing a long distance.

[0070] The first strip-shaped plate 26 is provided with a plurality of through holes 261, and the second strip-shaped plate 36 is provided with a plurality of through holes 361. The size and position of each through hole can be preset. The control system of the robot can determine the specific position of the vehicle body of the cleaning robot 4 on the first platform 2 or the second platform 3 according to the acquisition time interval of the feedback signal.

[0071] When the cleaning robot 4 travels on the photovoltaic panel array 1, the distance sensor will continuously obtain a feedback signal representing a short distance. After the cleaning robot 4 travels to the first platform 2, when the distance sensor is disposed opposite to the through hole 261 of the first strip-shaped plate 26, the distance sensor will not be able to obtain a feedback signal. The control system of the cleaning robot 4 determines that the cleaning robot 4 has traveled to the edge of the photovoltaic panel according to the continuous feedback signal obtained during the travel of the vehicle body, and controls the cleaning robot 4 to travel in the reverse direction, so that the cleaning robot 4 travels in the direction of the second platform 3 again.

[0072] When the cleaning robot 4 travels to the second platform 3, each distance sensor can be disposed opposite to a second strip-shaped plate 36. When the distance sensor is disposed opposite to the plate body of the second strip-shaped plate 36, the distance sensor will obtain a feedback signal representing a short distance. When the distance sensor is disposed opposite to the through hole 361, the distance sensor will not be able to obtain an effective feedback signal, or receive a feedback signal representing a long distance. The control system of the cleaning robot 4 determines that the cleaning robot 4 reaches the designated position of the second flat plate 3 according to the continuous feedback signal obtained during the travel of the vehicle body, and controls the cleaning robot 4 to automatically shut down, ending the cleaning of the photovoltaic panel array 1, so that the cleaning robot can be automatically charged through the second photovoltaic panel 42 in the idle state, and will not block the panel, thus not affecting the power generation amount, and there is no need for the staff to remove the cleaning robot from the photovoltaic panel array, thus effectively reducing the workload of the user.

[0073] The advantage of this embodiment is that it provides a photovoltaic system with a cleaning device. A robot is arranged on the top surface of the photovoltaic panel array, and a rolling brush is arranged in the middle of the bottom surface of the robot. A platform is respectively arranged at both ends of the photovoltaic panel array, effectively expanding the traveling space of the robot in the horizontal direction, so that part or all of the robot can travel outside the panel array, thereby ensuring that the part of the panel array near the edge of the panel array at both left and right ends can also be swept by the rolling brush of the robot, so as to ensure that there is no dead angle in the cleaning.

[0074] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
