Description

Technical Field

[0001] The present invention relates to the technical field of energy storage, and particularly to a floating photovoltaic power station automatic cleaning system based on a connecting bridge. Background Art

[0002] The components of a floating photovoltaic power station float on the water surface through buoyancy and brackets, and there is a certain displacement between adjacent photovoltaic components. The dry-hanging cleaning robots or ordinary crawler cleaning robots used in fixed-bracket photovoltaic power stations cannot operate on floating photovoltaic power stations. For example, dry-hanging cleaning robots require fixed tracks or use the fixed frames of photovoltaic components to operate, which is obviously not applicable to floating photovoltaic power stations. If an ordinary crawler cleaning robot is used, when it is placed on a certain component of a floating photovoltaic power station, due to the gravitational force of the cleaning robot, the photovoltaic component will sink to a certain extent, and the photovoltaic component will warp or press down as the center of gravity of the cleaning robot changes, resulting in the inability of the ordinary crawler cleaning robot to move to the surface of adjacent components. Therefore, there is an urgent need to develop an automatic cleaning device that can operate on floating photovoltaic power stations.

[0003] Therefore, there is an urgent need to design a sealing system to prevent the oxidation reaction of ternary salts, thereby improving the heat storage performance of the heat storage system. Summary of the Invention

The cleaning device can move along the cleaning passage and use the brush rollers to remove the dust on the surface of each photovoltaic panel group in the cleaning passage during the movement. During the movement of the cleaning device along the cleaning passage, the two limiting wheels of each pair of limiting wheel groups can fit the two side edges of the photovoltaic panel group and the two side edges of the overlapping plate in the cleaning passage, and the movement of the cleaning device along the cleaning passage is restricted by the limiting wheels.

[0006] Specifically, the lapping plate is an arc-shaped plate.

The guiding wheels arranged in the mounting holes at both ends of the arc-shaped track open the annular guiding belt, and the guiding wheels arranged in the mounting holes in the remaining arc-shaped track tighten the annular guiding belt so that the outer surface of the annular guiding belt forms an arc-shaped surface tangent to the surface of the photovoltaic panel group after being tightened. The robot is guided by the annular guiding belt to move from one photovoltaic panel of the photovoltaic panel group to the next photovoltaic panel.

[0009] Specifically, the cleaning device further includes a pair of cylinder frames. A cylinder frame is arranged at each of the two ends of the robot along the advancing direction of the robot.

Detailed implementation manners

[0019] The following will describe in detail the specific implementation manners of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0021] As Figures 1-6 shown, on the one hand, the present invention provides a floating photovoltaic power station automatic cleaning system based on a connecting bridge. The floating photovoltaic power station includes multiple rows of photovoltaic panel groups 10 arranged at intervals on the water surface. Each row of photovoltaic panel groups 10 includes multiple photovoltaic panels. The floating photovoltaic power station automatic cleaning system based on a connecting bridge includes: Multiple lapping plates 1. Between adjacent photovoltaic panel groups 10, they are sequentially connected end to end through one lapping plate 1 to form a continuous cleaning passage; A cleaning device 2, including a pair of brush rollers 21 and multiple pairs of limiting wheel groups. Each pair of limiting wheel groups includes two symmetrically arranged limiting wheels 22. The two limiting wheels 22 are respectively arranged on both sides of the advancing direction of the cleaning device 2. The cleaning device 2 can move along the cleaning passage, and during the movement, the dust on the surface of each photovoltaic panel group 10 in the cleaning passage is removed by the brush rollers 21. During the process of the cleaning device 2 moving along the cleaning passage, the two limiting wheels 22 of each pair of limiting wheel groups can be attached to the two side edges of the photovoltaic panel group 10 and the two side edges of the lapping plate 1 in the cleaning passage, and the movement of the cleaning device 2 along the cleaning passage is restricted by the limiting wheels 22.

[0022] The automatic cleaning system for a floating photovoltaic power station based on a connecting bridge provided by the present invention, as Figure 1 shown, connects the multi-row photovoltaic panel groups 10 end to end through overlapping plates to form a cleaning passage. The cleaning device 2 moves along the cleaning passage. During the movement, the brush rollers 21 of the cleaning device 2 clean the surfaces of the photovoltaic panel groups 10. The surfaces of the photovoltaic panels of the photovoltaic panel groups 10 are formed by the sides of multiple photovoltaic panels facing away from the water surface. Usually, during the use of the photovoltaic panels, a certain angle is set between the photovoltaic panels and the horizontal plane so that the photovoltaic panels can better absorb sunlight. The photovoltaic panel groups 10 formed by multiple photovoltaic panels correspondingly have a certain angle with the horizontal plane. To ensure that the cleaning device moves along the cleaning passage and prevent the cleaning device 2 from falling off the surface of the photovoltaic panel groups 10, limiting wheels 22 are provided on both sides of the cleaning device 2 along the advancing direction of the cleaning device 2. Each limiting wheel 22 on one side can contact the corresponding side edge of the photovoltaic panel group 10 and the corresponding side edge of the overlapping plate 1, so that the photovoltaic panel group 10 or the overlapping plate 1 is clamped between a pair of limiting wheels 22. In this way, the limiting wheels 22 on both sides of the cleaning device 2 can limit the cleaning device 2 to always move along the cleaning passage. At the same time, the limiting wheels 22 on both sides can also limit the cleaning device 2 on the cleaning passage when the photovoltaic panel groups 10 have a certain angle with the horizontal plane, preventing the cleaning device 2 from slipping off the cleaning passage, solving the problem that the cleaning robots provided in the prior art cannot complete the cleaning of the floating photovoltaic power station at one time, reducing the labor intensity of the staff, and improving the cleaning efficiency.

[0023] As Figure 1 shown, in order to enable the cleaning device 2 to smoothly move from one row of photovoltaic panel groups 10 to another row of photovoltaic panel groups 10 through the overlapping plate 1 for cleaning, the overlapping plate 1 is an arc-shaped plate. Arc-shaped plates are provided at the ends of two rows of photovoltaic panel groups 10. Through the arc-shaped plates, the limiting wheels 22 on both sides of the cleaning device 2 can smoothly move from the side edges of the photovoltaic panel groups 10 to fit the inner arc edge and the outer arc edge of the arc-shaped plate, so that the cleaning device 2 can smoothly move from one row of photovoltaic panel groups 10 to another row of photovoltaic panel groups 10, preventing the limiting wheels 22 from jamming at the overlapping plate 1 when the cleaning device 2 moves from one row of photovoltaic panel groups 10 to another row of photovoltaic panel groups 10.

[0024] The photovoltaic panel group 10 includes multiple photovoltaic panels. The photovoltaic panels in this application all float on the water surface. The photovoltaic panels in the photovoltaic panel group 10 are all connected through flexible connectors, and the photovoltaic panels move relative to each other. When the cleaning device 2 walks on one row of photovoltaic panel groups 10 and walks from one photovoltaic panel to an adjacent another photovoltaic panel, due to the weight of the robot 23 itself, a drop will occur between the photovoltaic panel where the robot 23 walks and the next photovoltaic panel. In order to enable the robot 23 to overcome the drop between the two photovoltaic panels and guide the robot 23 to walk from one photovoltaic panel to another photovoltaic panel, as Figure 2As shown, the cleaning device 2 further includes: a robot 23 and a pair of guiding components 24; The robot 23 is connected to a pair of brush rollers 21 and each limiting wheel 22. A brush roller 21 is provided at each end of the robot 23 along the advancing direction of the robot 23, and limiting wheels 22 are provided on both sides of the robot 23 along the advancing direction of the robot 23. The robot 23 can drive the brush rollers 21 to move along the cleaning channel; A pair of guiding components 24 are respectively provided at both ends of the robot 23 in the advancing direction. During the movement of the robot 23, the guiding components 24 guide the robot 23 to move from one photovoltaic panel of the photovoltaic panel group 10 to the next photovoltaic panel.

[0025] The guiding component 24 includes: a guiding bracket 241, an annular guiding belt 242, and a plurality of guiding wheels 243; The guiding bracket 241 is connected to the robot 23, and a plurality of mounting holes are formed in the guiding bracket 241. The plurality of mounting holes are sequentially connected to form an arc-shaped track; A plurality of guiding wheels 243 are provided on the guiding bracket 241. A guiding wheel 243 is correspondingly provided in each mounting hole. The guiding wheels 243 provided in the mounting holes at both ends of the arc-shaped track open the annular guiding belt 242, and the guiding wheels 243 provided in the remaining arc-shaped track tighten the annular guiding belt 242 so that after the annular guiding belt 242 is tightened, the outer surface of the annular guiding belt 242 forms an arc-shaped surface tangent to the surface of the photovoltaic panel group 10. The robot 23 is guided by the annular guiding belt 242 to move from one photovoltaic panel of the photovoltaic panel group 10 to the next photovoltaic panel.

[0026] Through the guiding component 24, the robot 23 can be guided to smoothly move from one photovoltaic panel to another on the cleaning channel, thereby completing dust cleaning. The robot 23 is a tracked robot. As Figure 5 and Figure 6 shown, the guiding bracket 241 is arc-shaped. The guiding bracket 241 is connected to the robot 23 through a connecting rod. Mounting holes are formed in the guiding bracket 241 along the circumferential direction of the guiding bracket 241 for mounting the guiding wheels 243. The guiding wheels 243 are rotatably arranged on the guiding bracket 241 through the mounting holes. The guiding wheels 243 at both ends of the arc-shaped track formed by connecting the plurality of mounting holes open the annular guiding belt, and the other annular guiding wheels 243 are used to tighten the annular guiding belt 242. As Figure 5As shown, the outer surface of the tensioned annular guiding belt 242 is an arc surface, and the arc surface can be tangent to the surface of the photovoltaic panel group 10. In this way, when the robot 23 walks from one photovoltaic panel to the next in a row of photovoltaic panel groups 10, the arc surface of the annular guiding belt 242 first contacts the next photovoltaic panel. When the robot 23 moves forward, it gradually presses down on one side of the next photovoltaic panel through the annular guiding belt 242 to temporarily eliminate the height difference, ensuring that the robot 23 can smoothly walk from one photovoltaic panel to the next. After the robot 23 walks to the end of the cleaning passage, the surface of the photovoltaic panel group 10 is cleaned. The robot 23 can also be controlled to walk reversely along the original cleaning passage, and the dust on the surface of the photovoltaic panel group 10 is cleaned again by the brush roller 21 at the other end. After completing the cleaning task, the robot 23 moves to the charging pile for charging.

[0027] To connect the brush roller 21 to the robot 23, the cleaning device 2 further includes a pair of cylinder frames 25. One cylinder frame 25 is respectively arranged at both ends of the robot 23 along the advancing direction of the robot 23. The cylinder frame 25 is movably connected to the robot 23, and the brush rollers 21 at both ends of the robot 23 are arranged on the robot 23 through a corresponding cylinder frame.

[0028] The brush roller 21 is installed on the cylinder frame 25. As Figure 6 shown, the cylinder frame 25 is movably connected to the robot 23, and the cylinder frame 25 can rotate around the connection part with the robot 23. The brush roller 21 has bristles and can rotate. When the robot 23 moves along the cleaning passage, the rotation of the brush roller 21 can clean the dust on the surface of the photovoltaic panel group 10. To drive the rotation of the brush roller 21, a brush roller driver is arranged on the cylinder frame 25 to drive the rotation of the brush roller 21 through the brush roller driver.

[0029] To install the limit wheel 22, the cleaning device 2 further includes a limit frame 26 with the same number as the limit wheel 22. The limit frames 26 are arranged on both sides of the robot 23 along the advancing direction of the robot 23. The limit frame 26 is connected to the cylinder frame 25, and a limit wheel 22 is correspondingly installed on each limit frame 26.

[0030] The limit frame 26 includes a limit cross bar 261 and a limit vertical bar 262 which are arranged perpendicular to each other. The limit cross bar 261 is connected to the cylinder frame 25. One end of the limit vertical bar 262 is movably connected to the limit cross bar 261, and the other end is connected to the limit wheel 22.

[0031] A limit groove is formed on the limit cross bar 261. One end of the limit vertical bar 262 extends into the limit groove and can move in the limit groove. By moving one end of the limit vertical bar 262 in the limit groove, the distance between the corresponding limit wheel 22 and the side of the photovoltaic panel group 10 can be adjusted.

[0032] The cleaning device 2 further includes a plurality of limit adjusting members 27. Each limit adjusting member 27 is disposed in the limit groove of the limit cross bar 261 of each limit frame 26, and is used to adjust the moving distance of the limit vertical bar 262 in the limit groove.

[0033] As Figure 2 and Figure 6 shown, limit frames 26 are installed on both sides of the cylinder frame 25. The limit wheels 22 are connected to the robot 23 through the limit frames 26 and the cylinder frame 25. As Figures 2-4 shown, the limit cross bar 261 of the limit frame 26 is connected to the cylinder frame 25. One end of the limit vertical bar 262 is a large end and the other end is a small end. A limit groove is formed in the limit cross bar 261. The size of the large end of the limit vertical bar 262 fits the size of the limit groove and the large end is movably disposed in the limit groove. A limit wheel 22 is connected to the small end of the limit vertical bar 262. When the large end of the limit vertical bar 262 moves in the limit groove, it can drive the limit wheel 22 to approach or move away from the corresponding side edge of the photovoltaic panel group 10 or the corresponding side edge of the lap joint plate 1. As Figure 3 shown, for the convenience of installation, a limit groove is formed on the side of the limit cross bar 261 facing away from the water surface, and a strip-shaped through hole is formed at the bottom of the limit groove. The large end of the limit vertical bar 262 is slidably disposed in the limit groove, and the small end of the limit vertical bar 262 passes through the strip-shaped through hole and is connected to the limit wheel 22. When the large end of the limit vertical bar 262 moves in the limit groove, the limit wheel 22 connected to the small end of the limit vertical bar 262 can approach or move away from the corresponding side edge of the photovoltaic panel or the lap joint plate 1.

[0034] To adjust the position of the limit vertical bar 262 in the limit groove, as Figure 4 shown, at both ends of the large end of the limit vertical bar 262 in the sliding direction of the limit groove, limit adjusting members 27 are respectively disposed between the large end of the limit vertical bar 262 and the groove wall of the limit groove. The limit adjusting members 27 are springs. Through the spring force of the limit adjusting members 27, the limit wheel 22 can better fit the corresponding side edge of the photovoltaic panel group 10 and the corresponding side edge of the lap joint plate 1, so as to better control the robot 23 to walk along the cleaning channel.

[0035] To better remove the dust on the surface of the photovoltaic panel, the cleaning device 2 further includes: a plurality of nozzles, which are connected to the cylinder frame 25, and through the plurality of nozzles, a cleaning liquid can be sprayed onto the surface of the photovoltaic panel group 10. The plurality of nozzles are disposed on the cylinder frame 25 in front of the brush roller 21 and are connected to supply the cleaning liquid to the plurality of nozzles. The cleaning liquid is ejected from the nozzles to wash the dust on the surface of the photovoltaic panel. Subsequently, when the robot 23 walks on the cleaning channel, the brush roller 21 removes the dust on the surface of the photovoltaic panel again.

[0036] The automatic cleaning system for a floating photovoltaic power station based on a connecting bridge provided by the present invention forms a cleaning passage by connecting the heads and tails of multiple groups of photovoltaic panels through the provided overlapping plates. The cleaning device can move along the cleaning passage. During the process of the cleaning device moving along the cleaning passage, the brush rollers can clean the dust on the surface of the photovoltaic panel groups. Moreover, during the process of the cleaning device moving along the cleaning passage, the cleaning device can also be restricted from moving along the cleaning passage by the limit wheels in the cleaning device to prevent the cleaning device from falling. The present application provides an automatic cleaning system for a floating photovoltaic power station based on a connecting bridge. The cleaning device can complete the cleaning of the dust on the photovoltaic panels of the floating photovoltaic power station at one time along the formed cleaning passage, solving the problem that the cleaning robots provided in the prior art cannot complete the cleaning of the floating photovoltaic power station at one time, reducing the labor intensity of the staff and improving the cleaning efficiency.
