Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panel cleaning, in particular to a horizontal track installation structure and a transport system. Background Art

[0002] Photovoltaic panels use the voltaic effect of semiconductor materials under light conditions to directly convert solar energy into electrical energy. To ensure power generation efficiency, photovoltaic panels are often tilted at an angle relative to the horizontal plane. Photovoltaic panels are installed outdoors, so dust or other attachments are easily accumulated on the surface of the panels, resulting in reduced power generation efficiency of photovoltaic panels.

[0003] When multiple photovoltaic panels are arranged to form a photovoltaic panel array, one or two photovoltaic panels are arranged as a unit along their length, and the above units are arrayed along the width direction of the photovoltaic panel to form a photovoltaic panel array, and there will be more than two sets of photovoltaic panel arrays in a power station. The surface of the photovoltaic panel needs to be cleaned regularly. In order to reduce the cost of manual cleaning and improve the cleaning efficiency, various cleaning robots are usually used to clean the surface of the photovoltaic panel in the prior art.

[0004] If a cleaning robot is installed on each set of photovoltaic panel arrays, the entire photovoltaic power station will need hundreds or thousands of cleaning robots, and the operating cost is too high; or if a cleaning robot is used, after the cleaning robot cleans one set of photovoltaic panel arrays, it will be manually moved to the next set of photovoltaic panel arrays, which wastes manpower and material resources.

[0005] In the prior art, a shuttle bus is usually used to transfer cleaning robots between multiple photovoltaic panel arrays. However, in large-scale photovoltaic power stations, the ground used to install photovoltaic panel arrays is generally uneven, that is, the height difference between each group of photovoltaic panel arrays and the ground on which they are located may be inconsistent, and there is no guarantee that the shuttle bus can move and dock smoothly. Even if the docking platform can be raised and lowered and the angle can be adjusted, due to the uneven ground, there is no guarantee that the docking platform of the shuttle bus can be located in the same plane as the photovoltaic panel array, making it difficult to dock. Once there is a height difference between the docking platform and the photovoltaic panel array, the cleaning robot is likely to slide from a height, making it difficult to achieve rapid transfer between the shuttle bus and the photovoltaic panel array.

[0006] Therefore, the applicant has developed a horizontal track installation structure and a horizontal transport system, which enables the shuttle vehicle to move horizontally on the horizontal track in an uneven venue, thereby ensuring that the top surface of the docking platform on top of the shuttle vehicle can be in the same plane as the top surface of the photovoltaic panel, so that the photovoltaic panel cleaning robot can quickly transfer between the photovoltaic panel and the docking platform.

[0049] like Figure 1-Figure 3 As shown, the utility model also provides a transport system, including a horizontal track mounting structure 100 and a vehicle body 200. The vehicle body 200 can move along two parallel straight rails 120 along the horizontal track mounting structure 100, and the vehicle body 200 is used to connect with a cleaning robot.

[0050] In this embodiment, after the cleaning robot has cleaned a group of first photovoltaic panel arrays 300, a platform that can be raised and lowered and rotated is provided above the vehicle body (not shown in the figure). When the vehicle body 200 moves along the track 120 to one side of the first photovoltaic panel array 300, the platform is raised and lowered and rotated so that the platform and the first photovoltaic panel array 300 are on the same plane. At this time, the cleaning robot moves to the platform. After the cleaning robot moves to the platform, the vehicle body 200 begins to move along the laid track to one side of the second photovoltaic panel array 300. When the platform and the second photovoltaic panel array 300 are on the same plane, the cleaning robot moves from the platform to the second photovoltaic panel array 300 to clean the second photovoltaic panel 300 array, and so on, until the cleaning robot has cleaned all photovoltaic panel arrays 300.

[0051] Furthermore, the vehicle body 200 includes a chassis frame 210, more than two sets of wheels 220 and more than two limiting rollers 230, and the more than two sets of wheels 220 are installed to the bottom of the chassis frame 210; when the wheels 230 move on the top surfaces of the two rails 120, the limiting rollers 230 can roll along the two outer walls of the chassis frame 210 to prevent the vehicle body 200 from tipping over when moving on the top surfaces of the two rails 120, and the limiting rollers 230 can ensure that the vehicle body 200 moves stably on the two rails 120.

[0052] like Figure 4 As shown, the vehicle body 200 also includes more than two roller brackets 240, each roller bracket 240 includes a first plate 250 and a second plate 260 vertically connected to each other, the first plate 250 is fixed to the side of the chassis frame 210, and the second plate 260 extends horizontally in a direction away from the chassis frame 210; each limiting roller 230 is rotatably mounted to a second plate 260, and the rotation axis of the limiting roller 230 is perpendicular to the second plate 260. During the movement of the vehicle body 200, the wheels 220 move along the top surfaces of the two rails 120, and the roller brackets 240 move along the sides of the two rails 120.

[0053] In this embodiment, the vehicle body 200 also includes a motor 270 and an electric control box 280. The motor 270 is used to drive a set of wheels 220 so that the vehicle body 200 can move on two tracks 120. The electric control box 280 is used to control the start and stop of the motor 270 and provide power to the motor 270.

[0054] like Figure 1 as well as Figure 5 As shown, the horizontal track installation structure 100 provided by the utility model comprises two or more installation bases 110 arranged opposite to each other, the installation bases 110 are H-shaped structures, two parallel linear tracks 120, two or more second connecting rods 130 and two or more tightened cable assemblies 140. Each installation base 110 comprises two oppositely arranged columns 111 and a first connecting rod 112, the two ends of the first connecting rod 112 are respectively detachably connected to the middle of the two columns 111; the track 120 is vertically connected to the first connecting rod 112 of the installation base 110; the two tracks 120 extend on the same horizontal plane; the second connecting rods 130 are arranged at intervals on both sides of each installation base 110; each second connecting rod 130 is vertically connected to the two tracks 120; the two ends of each second connecting rod 130 extend outside the two tracks 120; one end of each cable assembly 140 is connected to one end of a second connecting rod 130, and the other end of each cable assembly 140 is connected to the outer wall of the top or bottom end of the column 111.

[0055] In this embodiment, two parallel straight rails 120 are mounted on two or more mounting bases 100 arranged opposite to each other to form a bridge-like structure. Two or more second connecting rods 130 and two or more tensioned steel cable assemblies 140 are used to stabilize the bridge, and the cleaning robot moves on this bridge structure.

[0056] like Figure 2 As shown, the horizontal track mounting structure 100 is installed to one side of the photovoltaic panel array 300, and the gap between the horizontal track mounting structure 100 and the photovoltaic panel array 300 is sufficient for the cleaning robot to cross, ensuring that the platform and the photovoltaic panel array 300 are on the same plane, that is, when docking, the cleaning robot can cross back and forth between the platform and the photovoltaic panel array 300, thereby realizing the rapid transfer of the cleaning robot between different photovoltaic panel arrays 300.

[0057] like Figure 6-Figure 7 As shown, the first connecting rod 112 is an I-shaped member, and the first connecting rod 112 includes a first connecting rod body 113 and a first connecting plate 114 . The first connecting plate 113 is vertically connected to both ends of the first connecting rod body 114 .

[0058] Furthermore, the horizontal rail mounting structure 100 includes a first annular hoop 150 and a second connecting plate 151. The first annular hoop 150 is sleeved on the outer wall of the middle part of a column 111; the second connecting plate 151 is integrally connected to the first annular hoop 150; the second connecting plate 151 is connected to the first connecting plate 114 via a fastener 152. The first annular hoop 150 includes a bolt 153 for adjusting its inner diameter. By rotating the bolt 153, the inner diameter of the first annular hoop 150 is adjusted, so that the first annular hoop 150 can be fixed to the surface of the column 111, thereby fixing the first connecting rod 112 to the column 111.

[0059] In this embodiment, the column 111 is a retractable column 111. When the inner diameter of the first annular clamp 150 becomes larger, the end of the column 111 away from the ground can be moved in a direction away from the ground or in a direction close to the ground, thereby ensuring that the distance between each group of photovoltaic panel arrays 300 and the plane where the track 120 is located is the same, or the error between the distance between each group of photovoltaic panel arrays 300 and the plane where the track 120 is located is within a preset range, ensuring that a liftable and rotatable platform is provided above the vehicle body, and through lifting and rotating operations, the platform and each group of photovoltaic panel arrays 300 can be on the same plane, so that the cleaning robot can clean each group of photovoltaic panel arrays 300, eliminating the possibility that the vehicle body 200 cannot dock with individual photovoltaic panel arrays 300 due to ground factors, making it impossible for the cleaning robot to clean them.

[0060] like Figure 6 As shown, the horizontal track mounting structure 100 includes more than two angle irons 154, each angle iron 154 includes two side plates 155 perpendicular to each other, one side plate 155 abuts against the inner wall of a track 120, and the other side plate 155 is provided with a through hole 156, which is fixed to the top surface of a first connecting rod 112 or a second connecting rod 130 by a fastener 152, so that the track 120 is fixedly connected to the first connecting rod 112, and the track 120 is fixedly connected to the second connecting rod 130.

[0061] like Figure 8 As shown, the horizontal track installation structure 100 includes a first bolt 157 , which is threadedly connected to the side wall of each second connecting rod 130 , and the end of the first bolt 157 forms a first ring 158 .

[0062] like Fig. 9 As shown, the horizontal track mounting structure 100 includes a second annular hoop 159, which is sleeved on the outer wall of the top or bottom of a column 111; the second annular hoop 159 includes at least one second bolt 160 for adjusting its inner diameter, and the second bolt end 160 forms a second ring 161.

[0063] Another example Figure 5 As shown, the steel cable assembly 140 includes a bidirectional rope tensioner 141 and a steel wire rope 142. The two ends of the bidirectional rope tensioner 141 respectively form a connecting end 143, and the distance between the two connecting ends 143 can be adjusted; one end of the steel wire rope 142 is fixedly connected to a connecting end 143 of the bidirectional rope tensioner 141, and the other end of the steel wire rope 142 is fixedly connected to the first ring 158 or the second ring 161.

[0064] In this embodiment, both ends of each steel cable assembly 140 are connected to a first ring 158 and a second ring 161 respectively. By changing the distance between the two connecting ends 143 to tighten or loosen the steel wire rope 142, the horizontal track installation structure 100 is made more stable.

[0065] like Fig.10 As shown, the bidirectional rope tightener 141 includes a strip ring 144 and two third bolts 145. A nut 146 is provided at each end of the strip ring 144. One end of the third bolt 145 can be rotatably passed through the nut 146, and a hook 147 is formed at the other end. The distance between the two connecting ends 143 is adjusted by rotating the third bolt 145. The hook 147 is used to connect one end of the wire rope 142.

[0066] In this embodiment, the outer wall in the middle of the column 111 is provided with at least one annular groove (not shown), and the first annular hoop 150 and the second annular hoop 159 are arranged in the annular groove (not shown) to increase the stability of the surface of the column 11 and the annular hoop 150 and the second annular hoop 159.

[0067] In the application scenario of the utility model, for example, a horizontal track mounting structure 100 is laid in a power station with different ground heights, the power station includes more than two groups of photovoltaic panel arrays 300, the horizontal track mounting structure 100 is located on the side of the photovoltaic panel array 300, the mounting base 110 of the horizontal track mounting structure 100 is arranged at both ends of the side of the photovoltaic panel array 300, two straight-line rails 120 parallel to each other are laid on the first connecting rod 112 between the two columns 111 of the mounting base 110 to form a bridge, and the vehicle body 200 moves on the rail 120.

[0068] After the cleaning robot has cleaned a group of first photovoltaic panel arrays 300, a platform that can be raised and lowered and rotated is provided above the vehicle body 200 (not shown in the figure). When the vehicle body 200 moves along the track 120 to one side of the first photovoltaic panel array 300, the platform is raised and lowered and rotated so that the platform and the first photovoltaic panel array 300 are on the same plane. At this time, the cleaning robot moves to the platform. After the cleaning robot moves to the platform, the vehicle body 200 begins to move along the laid track to one side of the second photovoltaic panel array 300. When the platform and the second photovoltaic panel array 300 are on the same plane, the cleaning robot moves from the platform to the second photovoltaic panel array 300 to clean the second photovoltaic panel array 300, and so on, until the cleaning robot has cleaned all photovoltaic panel arrays 300.

[0069] The advantage of the present application is that it provides a horizontal track installation structure and a transport system, and by laying a horizontal track on the power station site, the cleaning robot can move smoothly on the horizontal track. The horizontal track installation structure includes two or more installation bases arranged opposite to each other, two straight rails parallel to each other, two or more second connecting rods and two or more tightened steel cable assemblies. The installation base and the rail form a bridge that can be used for shuttle vehicles to pass through. The second connecting rods and the steel cable assemblies are used to reinforce the bridge. The height of each group of photovoltaic panel arrays from the plane where the track is located can be fixed by lifting the rail, thereby ensuring that the shuttle vehicle can dock with all photovoltaic panel arrays. While achieving the smooth movement of the shuttle vehicle in the power station site, the possibility that the shuttle vehicle cannot complete the docking task due to ground factors is eliminated, thereby achieving the docking of the shuttle vehicle with the photovoltaic panel array on uneven ground and the rapid transfer of the cleaning robot between the photovoltaic panel and the docking platform.
