Description

Technical Field

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

[0002] Solar panels are placed outdoors for a long time during use, and dirt such as dust and bird droppings are easily accumulated on their surface, which affects the light transmittance and power generation efficiency of the solar panels. Therefore, it is necessary to clean the dirt on the solar panels regularly. At present, there are two main ways to clean solar panels: manual cleaning and mechanical cleaning. Although the manual cleaning method has a better cleaning effect, the cleaning efficiency is low, the labor intensity is high, the cleaning cost is high, and it is difficult to complete large-scale cleaning tasks. Although the mechanical cleaning method has a higher cleaning efficiency, the cleaning effect is slightly worse. For solar panels in areas with strong winds, more dust accumulates on their surfaces, and higher cleaning effects are required. When using traditional solar panel cleaning devices to clean dirt on the surface of solar panels, the cleaning effect can no longer meet the needs. Summary of the invention

[0014] At least one end of the spray plate is provided with a swing limit block; when the spray plate swings, the swing limit block can abut against the forward limit column or the backward limit column.

[0015] In some of the embodiments, a low position limiting column and a high position limiting column are provided on the inner wall of at least one end of the housing;

[0016] The opposite ends of the top of the baffle are rotatably connected to the opposite ends of the shell respectively; when the top of the baffle rotates, the top of the baffle can abut against the low-position limiting column or the high-position limiting column.

[0017] In some of the embodiments, a liquid inlet hole is formed on one side of the baffle plate close to the cleaning roller, and a liquid outlet hole is formed at one end; the liquid outlet hole is suitable for communicating with the negative pressure generator.

[0024] The partition cylinder can be inserted into the drum body or detached from the drum body to separate the ash inlet hole from the ash storage cavity or connect the ash inlet hole with the ash storage cavity.

[0025] In some embodiments, it also includes:

[0026] A walking mechanism capable of walking on the ground to drive the shell to move along the surface of the solar cell panel;

[0027] The mechanical arm has one end fixedly mounted on the walking mechanism and the other end connected to the shell, and can place the shell, the cleaning roller, the spray assembly, the baffle and the blower assembly on the walking mechanism or on the solar cell panel.

Therefore, the baffle is added to effectively prevent the cleaning liquid or dirt that falls off the cleaning roller from falling into the area that has been cleaned, thereby avoiding the area that has been cleaned from being polluted again. During the cleaning process, the air blowing assembly blows air toward the front side of the baffle, which is conducive to the cleaning liquid from the spray assembly falling to the front side of the cleaning roller to ensure the wetting effect of the area to be cleaned, and suppresses the flying of the cleaning liquid or dirt that falls off the cleaning roller, preventing the cleaning liquid or dirt from crossing the top of the baffle and falling to the area that has been cleaned, thereby avoiding secondary pollution. At the same time, the air blowing assembly blows air toward the back side of the baffle to air dry the area that has been cleaned, so that dust is not easy to adhere to the area that has been cleaned. When there is less dirt on the surface of the solar panel, the bristles rotate clockwise with the cleaning roller to clean the surface of the solar panel, gather the dust between the cleaning roller and the baffle, and the air blowing assembly blows air toward the front side of the baffle to suppress the flying of dust. On the whole, it can replace or assist manual work to complete the cleaning task of the solar panel. Compared with the traditional solar panel cleaning device, when cleaning the dirt on the surface of the solar panel, the cleaning effect is better and water resources are saved. During the cleaning process, it can prevent dust from being scattered from its original position to other positions on the surface of the solar panel, ensuring cleaning efficiency. It is suitable for use in various areas with strong winds, mountains, hills and plains, and is suitable for cleaning solar panels of various sizes, various inclination angles and various layout forms, which is conducive to promoting the development of photovoltaic power generation applications.

DETAILED DESCRIPTION

[0043] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] As described in the background technology, although the mechanical cleaning method has a high cleaning efficiency, the cleaning effect is slightly poor. For solar panels in windy areas, more dust accumulates on their surfaces, and higher cleaning effects are required. When using traditional solar panel cleaning devices to clean dirt on the surface of solar panels, the cleaning effect can no longer meet the requirements.

[0045] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The present invention provides a solar panel cleaning device, comprising a housing 110, a cleaning roller 120, a spray assembly 130, a baffle 140 and a blower assembly 150. The housing 110 is used to support the cleaning roller 120, the spray assembly 130, the baffle 140 and the blower assembly 150. A clearance opening is formed at the bottom of the housing 110. The housing 110 can move along the surface of the solar panel 200. The cleaning roller 120 is rotatably mounted at the bottom of the housing 110, and bristles 122 made of soft material are arranged on the side wall. The side wall of the cleaning roller 120 can pass through the clearance hole and fit the surface of the solar panel 200. The spray assembly 130 is swingably mounted at the upper part of the housing 110, and can spray cleaning liquid toward the cleaning roller 120 and both sides of the cleaning roller 120. The baffle 140 is swingably mounted in the housing 110 and is located on the common side of the spray assembly 130 and the cleaning roller 120. The air blowing assembly 150 is installed on the top of the housing 110 and can blow air toward two opposite sides of the baffle 140 .

[0046] When there is a lot of dirt on the surface of the solar panel 200, the surface of the solar panel 200 is cleaned by wet cleaning: the cleaning roller 120, the spray assembly 130, the baffle 140 and the blower assembly 150 move along the surface of the solar panel 200 with the housing 110. During this process, the spray assembly 130 sprays the atomized cleaning liquid toward the front side of the cleaning roller 120 to wet the area to be cleaned and prevent dust from flying. The spray assembly 130 also sprays the atomized cleaning liquid toward the cleaning roller 120 to wet the bristles 122 on the cleaning roller 120. The bristles 122 rotate counterclockwise with the cleaning roller 120 to scrub the surface of the solar panel 200. As needed, the spray assembly 130 can be swung to a certain angle by gravity or external force to improve the cleaning effect. By adjusting the rotation speed of the cleaning roller 120, the purpose of efficiently cleaning the solar panels 200 with different pollution levels can be achieved. With the help of the spray assembly 130, water resources are reasonably used and the waste of water resources is reduced. During the counterclockwise rotation of the cleaning roller 120, part of the cleaning liquid or dirt will be separated from the cleaning roller 120. Therefore, the baffle 140 is added to effectively prevent the cleaning liquid or dirt that falls off the cleaning roller 120 from falling to the area that has been cleaned, thereby avoiding secondary contamination of the area that has been cleaned. Moreover, the baffle 140 can be swung to a certain angle by gravity or external force, thereby improving the effect of preventing secondary contamination. During the cleaning process, the air blowing assembly 150 blows air toward the front side of the baffle 140, which is conducive to the cleaning liquid from the spray assembly 130 falling to the front side of the cleaning roller 120 to ensure the wetting effect of the area to be cleaned, and suppresses the flight of the cleaning liquid or dirt that falls off the cleaning roller 120, preventing the cleaning liquid or dirt that falls off the cleaning roller 120 from falling over the baffle 140 to the area that has been cleaned, thereby avoiding secondary contamination. At the same time, the air blowing assembly 150 blows air toward the rear side of the baffle 140 to dry the cleaned area, making it difficult for dust to adhere to the cleaned area.

[0047] When there is less dirt on the surface of the solar panel 200, the surface of the solar panel 200 is cleaned by dry cleaning: the cleaning roller 120, the spray assembly 130, the baffle 140 and the air blowing assembly 150 move along the surface of the solar panel 200 with the shell 110. During this process, the spray assembly 130 does not participate in the work, and the bristles 122 rotate clockwise with the cleaning roller 120 to clean the surface of the solar panel 200, gathering the dust between the cleaning roller 120 and the baffle 140. The air blowing assembly 150 blows air toward the front side of the baffle 140 to suppress the flying of dust.

[0048] On the whole, it can replace or assist manual work to complete the cleaning task of the solar panel 200. Compared with the traditional solar panel cleaning device, it has a better cleaning effect when cleaning the dirt on the surface of the solar panel 200, saving water resources. During the cleaning process, it can prevent dust from scattering from its original position to other positions on the surface of the solar panel 200, ensuring the cleaning efficiency. It is suitable for use in various areas such as strong winds, mountains, hills and plains, and is suitable for cleaning solar panels 200 of various sizes, various tilt angles and various layout forms, which is conducive to promoting the development of photovoltaic power generation.

[0049] Specifically, in the example, Figure 1 and Figure 3 As shown, the spray assembly 130 includes a spray plate 131 and a plurality of cleaning liquid inflow nozzles 132. A cleaning liquid flow cavity is formed inside the spray plate 131. A plurality of rows and columns of cleaning liquid spray outlets are formed at the bottom of the spray plate 131. The opposite ends of the spray plate 131 are rotatably connected to the opposite ends of the housing 110, respectively, so that the spray plate 131 can swing. A plurality of cleaning liquid inflow nozzles 132 are respectively fixedly mounted on the top of the spray plate 131. Cleaning liquids such as water or alcohol can flow into the cleaning liquid flow cavity through any one of the cleaning liquid inflow nozzles 132, and flow out of the spray plate 131 through any one of the cleaning liquid spray outlets.

[0050] Preferably, the number of cleaning liquid inlet nozzles 132 is 3, 4 or 5.

[0051] In some embodiments, a forward limit column 112 and a backward limit column 111 are provided on the inner wall of one end of the housing 110. Correspondingly, a swing limit block 1311 is provided at one end of the spray plate 131. The swing limit block 1311 is in a triangular structure. When the spray plate 131 swings, the swing limit block 1311 can abut against the forward limit column 112 or the backward limit column 111 to prevent the spray plate 131 from swinging excessively.

[0052] In other embodiments, Figure 4 As shown, a forward limit column 112 and a backward limit column 111 are provided on the inner walls at opposite ends of the housing 110. Correspondingly, a swing limit block 1311 is provided at opposite ends of the spray plate 131. The swing limit blocks 1311 at both ends are triangular structures. When the spray plate 131 swings, the swing limit blocks 1311 at both ends can respectively abut against the forward limit column 112 or the backward limit column 111 at the corresponding end to prevent the spray plate 131 from swinging excessively. Compared with the form of a single swing limit block 1311, the force is evenly distributed.

[0053] In some embodiments, a low-position limiting column 113 and a high-position limiting column 114 are provided on the inner wall of one end of the housing 110. The opposite ends of the top of the baffle 140 are rotatably connected to the opposite ends of the housing 110. When the top of the baffle 140 rotates, the top of the baffle 140 can abut against the low-position limiting column 113 or the high-position limiting column 114 to prevent the bottom of the baffle 140 from swinging excessively.

[0054] In other embodiments, a low-position limiting column 113 and a high-position limiting column 114 are provided on the inner walls at opposite ends of the housing 110. The opposite ends of the top of the baffle 140 are rotatably connected to the opposite ends of the housing 110. When the top of the baffle 140 rotates, the opposite ends of the top of the baffle 140 can abut against the low-position limiting column 113 or the high-position limiting column 114 at the corresponding end to prevent the bottom of the baffle 140 from swinging excessively.

[0055] In some embodiments, in order to prevent the baffle 140 from scratching the surface of the solar panel 200, the baffle 140 is made of a flexible material. The bottom of the baffle 140 is in continuous soft contact with the surface of the solar panel 200 to continuously push the stains to move along the surface of the solar panel 200 and prevent the stains from being retained in the cleaned area.

[0056] In other embodiments, such as Figure 5 As shown, the material of the baffle 140 is a rigid material. A plurality of liquid inlet holes 141 are formed on one side of the baffle 140 close to the cleaning roller 120. The plurality of liquid inlet holes 141 are arranged in rows. A liquid outlet hole 142 is formed at one end of the baffle 140. A temporary stain storage chamber is formed inside the baffle 140. The temporary stain storage chamber is connected to each liquid inlet hole 141 and the liquid outlet hole 142 respectively. The liquid outlet hole 142 is suitable for being connected to a negative pressure generator. The liquid outlet hole 142 is connected to the negative pressure generator, and each liquid inlet hole 141 generates negative pressure. When the stains are separated from the cleaning roller 120 and reach the side of the baffle 140 close to the cleaning roller 120, the stains are separated from the baffle 140 by means of negative pressure to reduce the possibility of secondary contamination. It should be noted that the negative pressure generator can be an air pump or a vacuum pump, etc.

[0057] Specifically, in the example, Figure 1 and Figure 3 As shown, a plurality of ventilation holes 115 are formed on the top of the housing 110. The plurality of ventilation holes 115 are distributed in a straight line. There are a plurality of air blowing assemblies 150, which correspond one to one with the plurality of ventilation holes 115 and are also distributed in a straight line. Each air blowing assembly 150 includes a driving motor 151 and a fan 152. The driving motor 151 is installed in the ventilation hole 115. The fan 152 is installed on the output shaft of the driving motor 151. The driving motor 151 drives the fan 152 to rotate to generate wind force.

[0058] Preferably, the driving motor 151 may be a stepping motor with lower manufacturing cost, or a servo motor with higher motion control accuracy.

[0059] In some embodiments, such as Figure 3 As shown, the cleaning roller 120 includes a roller body 121 and bristles 122. The roller body 121 is a solid structure, and the bristles 122 are installed on the side wall of the roller body 121, which has a good cleaning effect.

[0060] In other embodiments, such as Figure 6 and Figure 7 As shown, the cleaning roller 120 includes a roller body 121, bristles 122 and a partition cylinder 123. Bristles 122 are installed on the side wall of the roller body 121. An ash storage chamber is formed inside the roller body 121. A plurality of ash inlet holes 1211 are formed on the side wall of the roller body 121. Each ash inlet hole 1211 can be communicated with the ash storage chamber. An ash outlet hole 1212 connected to the ash storage chamber is formed at one end of the roller body 121. The ash outlet hole 1212 is suitable for communicating with a negative pressure generator. The partition cylinder 123 can be inserted into the roller body 121 or detached from the roller body 121 to isolate each ash inlet hole 1211 from the ash storage chamber or to connect each ash inlet hole 1211 to the ash storage chamber. It should be noted that when the surface of the solar panel 200 is cleaned by wet cleaning, the partition cylinder 123 is inserted into the roller body 121 to isolate each ash inlet hole 1211 from the ash storage chamber. When the surface of the solar panel 200 is cleaned by dry cleaning, the partition cylinder 123 is separated from the drum body 121, so that each ash inlet hole 1211 is connected to the ash storage chamber, and the ash outlet hole 1212 is connected to the negative pressure generator, so that each ash inlet hole 1211 generates negative pressure. During the clockwise rotation of the cleaning drum 120, the dust is quickly separated from the surface of the solar panel 200 and the cleaning drum 120 by means of negative pressure, thereby improving the cleaning efficiency and the cleaning effect. It should be pointed out that the negative pressure generator can be an air pump or a vacuum pump, etc.

[0061] Specifically, in the example, Figure 1 , Figure 8 and Fig. 9As shown, the solar panel cleaning device also includes a walking mechanism 160, a mechanical arm 170, a liquid supply assembly 180, a monitor 190 and a power supply. The walking mechanism 160 can walk on the ground and be used as a mobile and load-bearing tool. One end of the mechanical arm 170 is fixedly mounted on the walking mechanism 160, and the other end is connected to the housing 110, and the housing 110, the cleaning roller 120, the spray assembly 130, the baffle 140 and the blast assembly 150 can be placed on the walking mechanism 160 or on the solar panel 200. When the mechanical arm 170 places the housing 110, the cleaning roller 120, the spray assembly 130, the baffle 140 and the blast assembly 150 on the solar panel 200, the walking mechanism 160 walks on the ground, and the housing 110 is driven by the mechanical arm 170 to move along the surface of the solar panel 200. The liquid supply assembly 180 is installed on the walking mechanism 160, communicated with the spray assembly 130, and is used to supply cleaning liquid, so as to facilitate the local use of the cleaning liquid. The monitor 190 is installed on the traveling mechanism 160 for monitoring the cleaning process. The power supply is installed on the top of the traveling mechanism 160 for supplying power to the components that need power consumption.

[0062] Preferably, the traveling mechanism 160 can be a tracked vehicle or a wheeled vehicle according to the working terrain.

[0063] Preferably, an articulated seat 116 is provided at the top of the housing 110, and a connecting rod is provided in the middle of the articulated seat 116. The connecting rod can rotate around its own axis. One end of the mechanical arm 170 is fixedly mounted on the top of the walking mechanism 160, and the other end is connected to the housing 110 through the articulated seat 116. A parking position is provided at the top of the walking mechanism 160, and the housing 110 can be parked at the parking position with the help of the mechanical arm 170. The structure and working principle of the mechanical arm 170 are prior art and will not be described in detail here.
