Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic cleaning robot technology, and more specifically, to a walking wheel tire, a walking wheel, and a photovoltaic cleaning robot. Background Technology
[0002] As a representative of renewable energy, photovoltaic (PV) power plants have become an important part of the modern energy structure due to their clean, environmentally friendly, and renewable advantages. However, PV panels are constantly exposed to the elements, easily accumulating dust and dirt, which affects power generation efficiency. To address this issue, PV cleaning robots have emerged. These robots utilize cleaning devices such as roller brushes to easily remove dirt from the surface of PV modules, ensuring their high-efficiency power generation.
[0003] Most photovoltaic (PV) cleaning robots on the market currently use a roller brush dry sweeping method. While roller brush dry sweeping can effectively remove dust from the surface of PV modules, the cleaning range of the roller brush cannot cover the area near the wheels due to the limitation of the wheels. This makes it difficult to clean the dust on the sides and edges of the PV modules. The floating dust stirred up by the PV cleaning robot is blocked by the robot body and then deflects back onto the PV modules. The areas that can be cleaned by the roller brush can be removed, while the areas that cannot be cleaned by the roller brush will accumulate dust, eventually forming a dust band on the sides and edges of the PV modules.
[0004] Therefore, how to clean the dust from the edges of photovoltaic modules is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this application is to provide a walking wheel tire for cleaning dust from the edges of photovoltaic modules;
[0006] Another objective of this application is to provide a walking wheel and a photovoltaic cleaning robot having the aforementioned walking wheel tires.
[0007] To achieve the above objectives, this application provides the following technical solution:
[0008] The first aspect of this application provides a walking wheel tire, including a flexible tire body, one end of the flexible tire body facing the area to be cleaned is the cleaning end, the flexible tire body is provided with at least one blowing hole, the blowing hole includes at least one blowing port, and the blowing port is located on the end face of the cleaning end of the flexible tire body.
[0009] In one possible implementation, the blowing hole extends in a direction parallel to the axial direction of the flexible tire body;
[0010] or,
[0011] The blowing hole extends at an acute angle to the axial direction of the flexible tire body, and along the direction from away from the cleaning end to near the cleaning end, the blowing hole is inclined in a direction that gradually moves away from the axis of the flexible tire body.
[0012] In one possible implementation, one end of the blowing hole is the blowing port, and the other end is a closed end.
[0013] In one possible implementation, the flexible tire body is further provided with a reset hole, one end of which is connected to the blowing hole and the other end of which passes through the outer peripheral surface of the flexible tire body.
[0014] In one possible implementation, one end of the blowing hole is the blowing port, and the other end is the reset port. The reset port is located at the opposite end of the cleaning end of the flexible tire body, and the cross-sectional area of the reset port is smaller than the cross-sectional area of the blowing port.
[0015] And / or,
[0016] The cross-sectional area of the blowing hole gradually decreases along the direction from away from the dust removal end to near the dust removal end.
[0017] In one possible implementation, the soot blowing hole includes a first soot blowing section and a second soot blowing section that are connected to each other, the end of the first soot blowing section away from the second soot blowing section is the soot blowing port, and the end of the second soot blowing section away from the first soot blowing section is a closed end;
[0018] Along the direction from away from the dust removal end to near the dust removal end, the cross-sectional area of the first dust blowing section gradually decreases, while the cross-sectional area of the second dust blowing section gradually increases.
[0019] In one possible implementation, the cross-sectional areas of the first and second soot blowing sections at the connection point are equal.
[0020] In one possible implementation, the cross-sectional shape of the blowing hole is circular, elliptical, polygonal, or a shape composed of at least two geometric figures;
[0021] And / or,
[0022] There are multiple blowing holes, which are evenly distributed along the circumference of the flexible tire body.
[0023] The walking wheel tire provided in this application has at least one blowing hole on its flexible tire body, and the blowing port of the blowing hole is located on the end face of the cleaning end of the flexible tire body. When this walking wheel tire is used as the walking wheel of a photovoltaic cleaning robot, the weight of the photovoltaic cleaning robot acts on the contact point between the flexible tire body and the photovoltaic module, causing deformation at this contact point. As the flexible tire body rolls, the position of deformation changes sequentially. Because the flexible tire body has a blowing hole, when the contact point between the flexible tire body and the photovoltaic module is where the blowing hole is located, the deformation of the flexible tire body will compress the blowing hole, reducing its volume and generating compressed gas. This compressed gas is discharged from the blowing port of the blowing hole and acts on the area of the photovoltaic module to be cleaned, blowing up the floating dust in the area and achieving a cleaning effect.
[0024] A second aspect of this application provides a walking wheel for a photovoltaic cleaning robot, including a walking wheel hub and a walking wheel tire fitted on the walking wheel hub, wherein the walking wheel tire is the walking wheel tire as described in any of the preceding claims.

[0047] This application discloses a walking wheel tire for cleaning dust from the edges of photovoltaic modules;
[0048] This application also discloses a walking wheel with the above-mentioned walking wheel tires and a photovoltaic cleaning robot.
[0049] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0050] like Figures 1-4 As shown in the embodiment of this application, a walking wheel tire is disclosed. The walking wheel tire is used to be fitted on the walking wheel hub 111 to form a walking wheel 110, so that the photovoltaic cleaning robot 100 can walk on the surface of the photovoltaic module 200 to clean various areas of the photovoltaic module 200.
[0051] The walking wheel tire includes a flexible tire body 112. As those skilled in the art will understand, the flexible tire body 112 is used to contact the photovoltaic module 200 and move in the corresponding direction by utilizing the friction between the tire body and the photovoltaic module 200. The flexible tire body 112 is usually made of a flexible material (such as rubber, silicone, etc. In this embodiment, the specific material of the flexible tire body 112 is not limited, as long as it can be deformed under pressure and can return to its original position after the pressure decreases or disappears). Therefore, it has a certain deformation capability. The weight of the photovoltaic cleaning robot 100 acts on the flexible tire body 112, so when the photovoltaic cleaning robot 100 moves, the position where the flexible tire body 112 contacts the photovoltaic module 200 can deform.
[0052] The end of the flexible tire body 112 facing the area to be cleaned is the cleaning end. The area to be cleaned is the area that the roller brush of the photovoltaic cleaning robot 100 cannot clean, that is, the area near the end of the roller brush, which is also the area on the side of the walking wheel facing the roller brush. The cleaning end of the flexible tire body 112 is the end of the flexible tire body 112 facing the roller brush.
[0053] The flexible tire body 112 is provided with at least one blowing hole 1121, and the blowing hole 1121 includes at least one blowing port 1122, which is located on the end face of the cleaning end of the flexible tire body 112. The blowing hole 1121 may have only one blowing port 1122 or multiple blowing ports 1122. Regardless of whether there is one or multiple blowing ports 1122, the blowing ports 1122 are all arranged on the end face of the cleaning end of the flexible tire body 112, allowing the blowing ports 1122 to blow air into areas that the roller brush cannot clean. When a blowing hole 1121 includes multiple blowing ports 1122, the airflow direction of each blowing port 1122 can be parallel or radial.
[0054] During cleaning operations, the photovoltaic cleaning robot 100's wheels 110 roll along the photovoltaic module 200. The weight of the robot acts on the contact point between the flexible tire body 112 and the photovoltaic module 200, causing deformation at this point. As the flexible tire body 112 rolls, the deformation location changes sequentially. Since the flexible tire body 112 has blowing holes 1121, when the contact point between the flexible tire body 112 and the photovoltaic module 200 is where the blowing holes 1121 are located, the deformation of the flexible tire body 112 compresses the blowing holes 1121, reducing their volume and generating compressed gas. This compressed gas is discharged from the blowing port 1122 of the blowing holes 1121 and acts on the area of the photovoltaic module 200 to be cleaned, blowing up the floating dust and achieving a cleaning effect. Some of the dust blown up will flow with the air to other areas, while some will flow to areas that the roller brush can clean, making it easier for the roller brush to clean.
[0055] In one specific embodiment of this application, the extending direction of the blowing hole 1121 can be parallel to the axial direction of the flexible tire body 112. This arrangement allows the airflow from the blowing hole 1121 to flow at an angle substantially parallel to the axis of the traveling wheel, that is, the airflow from the blowing hole 1121 is substantially parallel to the plane of the photovoltaic module 200.
[0056] The extension direction of the blowing hole 1121 can also be at an acute angle to the axis of the flexible tire body 112, and along the direction from away from the cleaning end to near the cleaning end, the blowing hole 1121 is inclined in a direction that gradually moves away from the axis of the flexible tire body 112. This arrangement makes the airflow blown out of the blowing hole 1121 flow at an acute angle to the axis of the traveling wheel, that is, the airflow blown out of the blowing hole 1121 forms an obtuse angle with the plane of the photovoltaic module 200, making it easier to blow up the accumulated dust on the area to be cleaned.
[0057] like Figure 4As shown, one end of the blowing hole 1121 is the blowing port 1122, and the other end is the closed end 1123. That is, the end of the blowing hole 1121 away from the blowing port 1122 is blocked, so that it is in a closed state. This ensures that when the blowing hole 1121 is squeezed, its air outlet direction is concentrated at the end where the blowing port 1122 is located, and ensures that the airflow blown out from the blowing port 1122 has sufficient impact force to improve the ability to clean up the accumulated ash.
[0058] like Figure 14 As shown in a specific embodiment of this application, a reset hole 1125 is also provided on the flexible tire body 112. One end of the reset hole 1125 is connected to the blowing hole 1121, and the other end extends through the outer peripheral surface of the flexible tire body 112. This embodiment adds a reset hole 1125 connecting the blowing hole 1121 and the outer peripheral surface of the flexible tire body 112. The setting of the reset hole 1125 can accelerate the volume recovery of the blowing hole 1121.
[0059] When the photovoltaic cleaning robot 100 is cleaning, when the contact point between the flexible tire body 112 and the photovoltaic module 200 is the location of the blowing hole 1121, the deformation of the flexible tire body 112 will squeeze the blowing hole 1121, causing the volume of the blowing hole 1121 to shrink, thereby forming cleaning gas blown out from the blowing port 1122. The cleaning gas blows up the floating dust in the area to be cleaned, so as to achieve the cleaning effect.
[0060] As the wheels 110 roll, when the location of the blowing hole 1121 moves away from the photovoltaic module 200, the area where the blowing hole 1121 is located loses the pressure from the photovoltaic cleaning robot 100 and gradually returns to its initial volume. During the volume recovery of the blowing hole 1121, gas can enter the blowing hole 1121 not only through the blowing port 1122 but also through the reset hole 1125, which can accelerate the volume recovery of the blowing hole 1121. Furthermore, since the airflow from the blowing port 1122 is used to blow up the accumulated dust in the area to be cleaned, the blowing port 1122 easily draws the raised dust back into the blowing hole 1121 during volume recovery. During the next cleaning cycle, the dust will be blown out again, affecting the cleaning effect.
[0061] In this embodiment, when the volume of the blowing hole 1121 is restored, air is introduced not only through the blowing port 1122 but also through the reset hole 1125. This reduces the amount of air introduced through the blowing port 1122, thereby reducing the amount of dust drawn back into the blowing hole 1121 through the blowing port 1122. The reset hole 1125 is connected to the outer peripheral surface of the flexible tire body 112 and is far from the dust-blown area, thus the amount of dust in the intake air is low.
[0062] Furthermore, the centerline of the blowing hole 1121, the centerline of the reset hole 1125, and the axis of the flexible tire body 112 are all located in the same plane. This arrangement ensures that during cleaning operations, when the contact point between the flexible tire body 112 and the photovoltaic module 200 coincides with the location of the blowing hole 1121, the photovoltaic module 200 can block the reset hole 1125. This prevents the airflow from being expelled solely from the blowing port 1122 when the flexible tire body 112 deforms and compresses the blowing hole 1121, thus increasing the impact force of the blowing airflow and improving the cleaning effect.
[0063] like Figure 13 As shown in a specific embodiment of this application, one end of the blowing hole 1121 is a blowing port 1122, and the other end is a reset port 1124. That is, in this embodiment, the two ends of the blowing hole 1121 pass through the two end faces of the flexible tire body 112 in the axial direction, and corresponding openings are formed on the two end faces. One opening is the blowing port 1122, and the other is the reset port 1124.
[0064] The reset port 1124 is located at the opposite end of the cleaning end of the flexible tire body 112, and the cross-sectional area of the reset port 1124 is smaller than that of the blowing port 1122. In this embodiment, designing the cross-sectional area of the reset port 1124 to be smaller than that of the blowing port 1122 reduces the amount of gas discharged from the reset port 1124, ensuring that the blowing port 1122 has sufficient blowing strength. When the volume of the blowing hole 1121 is restored, air is introduced through both the blowing port 1122 and the reset port 1124, thus reducing the amount of air introduced through the blowing port 1122 and consequently reducing the amount of dust drawn back into the blowing hole 1121 through the blowing port 1122. Furthermore, the reset port 1124 is connected to the opposite end of the cleaning end and is far from the dust-blown area, therefore the dust content in the intake air is low.
[0065] In addition, since the cross-sectional area of the reset port 1124 is designed to be smaller than that of the soot blowing port 1122, the reset port 1124 is more easily squeezed and closed when the soot blowing port 1121 is squeezed, which can reduce the amount of air leakage through the reset port 1124, or even completely close the reset port 1124 to prevent air leakage through the reset port 1124.
[0066] To further enhance the blowing intensity of the soot blowing hole 1121 and improve the cleaning effect, in this embodiment, the cross-sectional area of the soot blowing hole 1121 gradually decreases along the direction from away from the cleaning end to near the cleaning end. In this embodiment, the soot blowing hole 1121 is designed with a non-uniform cross-section structure, which can create an airflow acceleration effect when air is blown through the soot blowing hole 1121, thereby enhancing the intensity of the airflow and improving the cleaning ability. It should be noted that the soot blowing hole 1121 can also adopt a uniform cross-section structure.
[0067] like Figure 15 As shown, in one specific embodiment, the soot blowing hole 1121 includes a first soot blowing section 1121a and a second soot blowing section 1121b that are connected to each other. The end of the first soot blowing section 1121a away from the second soot blowing section 1121b is the soot blowing port 1122, and the end of the second soot blowing section 1121b away from the first soot blowing section 1121a is the closed end.
[0068] Along the direction from away from the dust removal end to near the dust removal end, the cross-sectional area of the first dust blowing section 1121a gradually decreases, which can create an airflow acceleration effect when air is blown through the dust blowing hole 1121, thereby enhancing the intensity of the airflow and improving the dust removal capability.
[0069] Along the direction from away from the dust removal end to near the dust removal end, the cross-sectional area of the second dust blowing section 1121b gradually increases. The cross-sectional areas of the first dust blowing section 1121a and the second dust blowing section 1121b at the connection point can be designed to be equal. With this arrangement, the position with the largest cross-section of the dust blowing hole 1121 is the closed end, making it easier to compress the position with the largest cross-section of the dust blowing hole 1121, thereby increasing the compression ratio of the dust blowing hole 1121, which in turn increases the intensity of the airflow and improves the dust removal capability.
[0070] The blowing hole 1121 disclosed in this application embodiment can have any cross-sectional shape, for example, it can be Figures 1-4 The image shown is circular, but it could also be... Figures 5-8 The triangle shown can also be Figures 9-12 The figure shown is composed of multiple geometric shapes.
[0071] When the cross-sectional shape of the blowing hole 1121 is triangular, the triangular blowing hole 1121 guides the airflow when it is squeezed, and can fix the airflow direction.
[0072] When the cross-sectional shape of the soot blowing hole 1121 is circular, the force exerted on the airflow by the hole wall of the soot blowing hole 1121 is relatively uniform when compressed, and the airflow can maintain a relatively stable state. The airflow blown out from the soot blowing hole 1121 can form a wind column in a more concentrated manner, reducing the dispersion and turbulence of the airflow and making the blowing more directional.
[0073] When the cross-sectional shape of the soot blowing hole 1121 is a shape composed of multiple geometric figures, for example Figure 11 The illustrated plum blossom-shaped blowing hole 1121 includes a central hole and a plurality of peripheral holes communicating with and surrounding the central hole. When compressed, the peripheral holes disperse the airflow, which then converges with the airflow from the central hole, forming a unique airflow combination. This dispersion and convergence process allows for thorough mixing and acceleration of the airflow, thereby enhancing the blowing force.
[0074] It should be noted that the cross-sectional shape of the blowing hole 1121 can also be a rectangle, a square, a trapezoid, or other polygons, ellipses, or other shapes composed of at least two geometric figures.
[0075] In one specific embodiment of this application, there are multiple blowing holes 1121, evenly distributed along the circumference of the flexible tire body 112. Of course, the arrangement of the blowing holes 1121 can be selected according to requirements, and an even distribution is not mandatory. Those skilled in the art can set the arrangement density of the blowing holes 1121 according to requirements. The more blowing holes 1121 there are, the greater the density, the smaller the missed area during blowing, and the better the blowing effect. The cross-sectional shape of each blowing hole 1121 can be the same, so that each blowing hole 1121 has the same blowing effect. Alternatively, at least two of the blowing holes 1121 can be designed with different cross-sectional shapes.
[0076] The flexible tire body 112 can have only one or at least two blowing rings. Each blowing ring includes multiple blowing holes 1121 arranged along the circumference of the flexible tire body 112. Due to the limited wall thickness of the flexible tire body 112, when multiple blowing rings are provided, the blowing holes 1121 of adjacent rings can be staggered. Taking two blowing rings as an example, for ease of understanding, the two blowing rings are defined as the first blowing ring and the second blowing ring, respectively. The blowing holes 1121 of the first and second blowing rings are arranged at different diameters of the flexible tire body 112. The blowing holes 1121 of the second blowing ring are located between two adjacent blowing holes 1121 of the first blowing ring. This arrangement reduces the wall thickness occupied by the first and second blowing rings of the flexible tire body 112, allowing for the arrangement of multiple blowing rings with a relatively thin wall thickness. Of course, the blowing holes 1121 of the first and second blowing rings can also be set one-to-one, that is, the line connecting the blowing holes 1121 of the first and second blowing rings passes through the axis of the flexible tire body 112.
[0077] When multiple blowing rings are provided on the flexible tire body 112, the blowing holes 1121 of each blowing ring can be evenly distributed along the circumference of the flexible tire body 112. The even distribution of the blowing holes 1121 in each blowing ring can ensure the uniformity of blowing dust off the traveling wheel. Of course, the density of the blowing holes 1121 in each blowing ring can also be set according to requirements, and it is not necessary to adopt an even distribution method.
[0078] When multiple blowing rings are provided on the flexible tire body 112, the number of blowing holes 1121 in each ring can be the same or different. That is, those skilled in the art can select the arrangement density of the blowing holes 1121 in each ring according to their needs. For example, the outer ring can be provided with a larger number of blowing holes, while the inner ring can be provided with a smaller number of blowing holes. Firstly, the outer ring is arranged on the larger diameter of the flexible tire body 112, providing more arrangement space, thus allowing for a larger number of blowing holes 1121. Secondly, the blowing holes 1121 of the outer ring are closer to the photovoltaic module, and a larger number of blowing holes 1121 can produce a better blowing effect on the photovoltaic module.
[0079] The cross-sectional shape of the blowing holes 1121 in each ring of the blowing ring is the same, ensuring that each blowing hole 1121 has the same blowing effect. Alternatively, the cross-sectional shape of the blowing holes 1121 in each ring of the blowing ring can be designed to be different. For example, the cross-sectional shape of the blowing holes 1121 in the same ring of the blowing ring can be designed to be the same, but the cross-sectional shape of the blowing holes 1121 in different rings of the blowing ring can be designed to be different. Alternatively, the cross-sectional shape of at least two blowing holes 1121 in the same ring of the blowing ring can be designed to be different.

The inner hub sleeve 1112 and the outer hub sleeve 1111 are connected by spokes 1113. The inner hub sleeve 1112 is rotatably fitted onto the axle of the photovoltaic cleaning robot 100 to enable the installation of the wheel 110 on the photovoltaic cleaning robot 100.
[0082] like Figure 2 As shown, the photovoltaic cleaning robot 100 disclosed in this application includes the walking wheels 110 disclosed in the above embodiment. Since the photovoltaic cleaning robot 100 disclosed in this application has the aforementioned walking wheels 110, it possesses all the technical effects of the aforementioned walking wheels 110, which will not be repeated here.
