Abstract
Description
Technical Field
[0001] This disclosure relates to the field of photovoltaic panel cleaning equipment, and more specifically, to a tracked solar panel high-efficiency cleaning device. Background Technology
[0002] A solar panel is an assembly made up of multiple solar cells. It is the core and most important part of a solar power generation system. Since most solar panels are installed on rooftops or in deserts, they accumulate a lot of dust and dirt over long-term use. Therefore, they need to be cleaned with cleaning equipment to ensure the power generation efficiency of the solar panels.
[0003] In existing technologies, roller-type brushes are commonly used to clean the surface of solar panels. During the brush rotation cleaning process, dust or sand inside the brush bristles or in front of the brush are picked up and splashed to the clean area behind, resulting in unsatisfactory cleaning effect. Multiple cleaning cycles are required to achieve the cleaning purpose, resulting in low cleaning efficiency. In addition, dust and debris accumulate in front of the brush and inside the brush bristles during the cleaning process, which can easily lead to brush jamming and failure. This results in a short service life of the equipment and low maintenance costs.
[0004] Therefore, it is necessary to design a high-efficiency cleaning device that employs different cleaning methods to solve the problems existing in the cleaning of solar panels.
[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0006] The purpose of this disclosure is to provide a highly efficient cleaning device for tracked solar panels, thereby overcoming, at least to some extent, one or more problems caused by limitations and defects in related technologies.
[0007] According to one aspect of this disclosure, a tracked solar panel high-efficiency cleaning device is provided, comprising a cleaning track, a frame, a mounting bracket, four walking assemblies, and two track rollers; wherein...
[0008] Two track rollers are installed at both ends of the frame. The cleaning track has a ring structure, with its two ends respectively fitted onto the two track rollers. Its outer surface has bristles. The cleaning track is arranged along the width of the solar panel. Its lower cleaning surface is in close contact with the surface of the solar panel and covers the width of the solar panel. Driven by the track rollers, the cleaning track rotates and cleans along the width of the solar panel.
[0009] The frame is supported by four walking assemblies located below, which drive the cleaning device to move along the length of the solar panel;
[0010] The frame is located in the middle of the sweeping track, and the mounting frame is set up above the sweeping track for installing and fixing electrical components. The two side legs of the mounting frame are connected to the frame.
[0011] In an exemplary embodiment of this disclosure, track roller seats for mounting track rollers are provided at both ends of the frame. The track roller seat includes a roller seat plate and a sliding support. The roller seat plate is detachably connected to the end of the frame. A rectangular stepped platform is raised on the roller seat plate. A sliding groove that mates with the stepped platform is opened on the side of the sliding support. The two stepped platforms on the two track roller seats jointly position the roller mounting plane. The two ends of the track roller are supported by the sliding support. The sliding support is bolted to the roller seat plate.
[0012] In an exemplary embodiment of this disclosure, the cleaning device is further provided with guide mechanisms at both ends. There are at least four guide mechanisms, each including a guide wheel and a mounting shaft. The guide wheel rolls on the side surface of the solar panel, and the mounting shaft is fixed to the sliding support and perpendicular to the roller mounting plane. The guide wheel is rotatably disposed at the bottom end of the mounting shaft.
[0013] In one exemplary embodiment of this disclosure, the walking assembly includes a walking wheel, a shock absorber assembly, an adapter plate, and a connecting bracket. One end of the connecting bracket is pin-connected to the adapter plate, and the other end is fixedly connected to the walking wheel. One end of the shock absorber assembly is pin-connected to the adapter plate, and the other end is pin-connected to the walking wheel. The shock absorber assembly, the adapter plate, and the connecting bracket form an elastic triangular support structure. The adapter plate is bolted to the side of the frame.
[0014] In one exemplary embodiment of this disclosure, two or four walking assemblies are self-driven walking assemblies, and the corresponding walking wheels are active walking wheels or driven walking wheels. The connecting bracket is an active connecting bracket or a driven connecting bracket. The active walking wheel has its own drive motor, and the other end of the connecting bracket is integrally formed with a mounting hoop, and the hoop sleeve of the drive motor is installed in the mounting hoop. The other end of the driven connecting bracket is provided with a support cylinder, and the driven walking wheel is rotatably mounted on the support cylinder.
[0015] In one exemplary embodiment of this disclosure, the sweeping device is provided with at least one tensioning mechanism, which is located in the middle of the sweeping track and installed in the middle of the track roller seat. The tensioning mechanism includes a mounting plate, a mounting bracket, an elastic tensioning assembly, and a tensioning wheel. The mounting plate is bolted to the track roller seat. The mounting plate, the mounting bracket, and the elastic tensioning assembly form an elastic triangular support structure. The tensioning wheel is rotatably disposed at the end of the mounting bracket and presses against the inner upper surface of the sweeping track above it.
[0016] In one exemplary embodiment of this disclosure, the skeleton is formed by welding together metal tubes arranged in a crisscross pattern, and connecting structures are respectively provided at the ends of the metal tubes on both sides and both ends of the skeleton.
[0017] An exemplary embodiment of this disclosure discloses a tracked solar panel high-efficiency cleaning device that uses the rotational motion of a ring-shaped cleaning track for brushing. Since the cleaning surface of the track covers the width of the solar panel, and the rotation direction is along the width of the solar panel, this achieves three advantages: First, it increases the cleaning contact area, allowing for multiple brushings of the same location during a single trip, effectively removing stubborn adhesives from the panel surface. Second, the cleaning track can transport dust and debris from the panel surface to the end for removal. Third, the cleaning track surface contacts the panel surface and brushes perpendicular to the walking direction, preventing dust and debris from being splashed into the cleaned area behind the device. Therefore, this cleaning device can complete the cleaning of the entire solar panel area in a single trip, effectively improving cleaning efficiency and providing outstanding cleaning results. Dust and debris are removed promptly, ensuring the cleanliness of the brush bristles and extending the device's service life.

Detailed implementation method.
[0027] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.
[0028] In this example embodiment, a high-efficiency cleaning device for tracked solar panels is first provided; Reference Figures 1-6 As shown, this tracked solar panel high-efficiency cleaning device includes a cleaning track 4, a frame 1, a mounting frame 5, four walking assemblies 2, and two track rollers 6, wherein:
[0029] According to one aspect of this disclosure, a high-efficiency cleaning device for tracked solar panels is provided. The circumferential surface of a track roller 6 contacts the inner surface of a cleaning track 4. One track roller 6 is a driving roller that drives the cleaning track 4 to rotate, and the other track roller 6 is a driven roller. The two track rollers 6 are installed at both ends of a frame 1, ensuring that their axial directions are parallel. The cleaning track 4 has a ring structure, with its two ends respectively fitted onto the two track rollers 6. When placing the cleaning device, the cleaning track 4 should be arranged along the width direction of the solar panel 9. The outer surface of the cleaning track 4 has bristles. With the support of 2, the front end of the brush of the lower cleaning surface extends 3-5cm below the walking assembly 2, so that it is in close contact with the surface of the solar panel 9, and achieves cleaning movement under the rotational driving force; in order to remove accumulated dust and debris during the cleaning process, the lower cleaning surface covers the width of the solar panel 9. Therefore, under the rotational drive of the track roller 6, the cleaning track 4 rotates and cleans along the width direction of the solar panel 9, while conveying dust and debris from one side of the solar panel 9 to the other side. Under the return rotational movement of the other side of the cleaning track 4, the dust and debris are thrown outside the solar panel 9.
[0030] Four walking assemblies 2 are distributed in a dot matrix around the center of gravity of the cleaning device and installed below the frame 1 as support, guide and drive for walking. The rotation center of the walking assembly 2 is parallel to the width direction of the solar panel 9, and it drives the cleaning device to walk along the length direction of the solar panel 9. Thus, a single walk can complete the cleaning work of the entire surface area of the solar panel.
[0031] Mounting bracket 5 is mounted above the sweeping track 4 and corresponds to the middle of the sweeping track 4. It is used to install and fix the electrical components of the sweeping device, such as power supply, control circuit, wires and cables, and control switches. The electrical components need to be evenly and balancedly distributed symmetrically with the center of gravity as the center. The frame 1 is located in the middle of the sweeping track 4. The two side legs of mounting bracket 5 extend downward to the middle of the sweeping track 4 and connect the mounting structures on both sides of the frame 1.
[0032] In this example embodiment, the frame 1 is formed by welding together crisscrossing metal tubes or strip beams, and mounting structures are respectively provided at both ends and both sides of the frame 1. The mounting structures on both sides are arranged in pairs and should be symmetrical about the center line of gravity. Figure 2 As shown, the mounting structure can be either a flat mounting plate 81 or a flange face. The mounting structure is located at the end of the corresponding metal pipe or strip beam and is an integrally formed structure. The metal pipe or strip beam should be made of high-strength and lightweight materials.
[0033] In one exemplary embodiment of this disclosure, in order to better position the track rollers 6 at both ends of the frame 1, the mounting structures at both ends of the frame 1 are bolted to the track roller seats 3. The track roller seats 3 are used to mount the track rollers 6, and include roller seat plates 31 and sliding supports 32. Referring again to Figure 4 The roller seat plate 31 is bolted to two mounting structures at the end of the frame 1. To ensure that the two track rollers 6 are axially parallel and that the roller mounting plane is parallel to the surface of the solar panel 9, so that the lower cleaning surface of the cleaning track 4 can evenly contact the surface of the solar panel 9, a rectangular stepped platform is provided on the roller seat plate 31. The two stepped platforms on the two track roller seats 3 jointly position the roller mounting plane. Under the support of the walking assembly 2, the roller mounting plane is adjusted to be parallel to the horizontal plane, and the roller seat plate 31 is fixed with bolts. The sliding support 32 is provided with mounting holes for installing the track rollers 6. Its side is provided with a sliding groove that cooperates with the stepped platform. Through the cooperation of the sliding groove with the stepped platform, the track rollers 6 are kept horizontal. At the same time, under the vertical limit of the stepped platform, the phenomenon of track rollers 6 moving up and down during the rotation of the cleaning track 4 can be avoided. After the track rollers 6 are positioned, the sliding support 32 and the roller seat plate 31 are bolted together.
[0034] In one exemplary embodiment of this disclosure, since the solar panel 9 is inclined at a certain angle in the width direction, in order to better achieve the movement of the panel surface, such as... Figure 4 and Figure 6 As shown, the cleaning device is also equipped with guide mechanisms 7 at both ends for guiding its movement along the side edge of the solar panel 9. There are at least four sets of guide mechanisms 7. Since the guide mechanism 7 uses the upper side edge of the solar panel 9 as its guide and also needs to support the entire cleaning device, at least two sets of guide mechanisms 7 are provided at the upper end. Two sets of guide mechanisms 7 at the upper end are sufficient. (Refer to...) Figure 4 The guiding mechanism 7 includes a guide wheel 71 and a mounting shaft 72. The guide wheel 71 is rotatably mounted on the bottom end of the mounting shaft 72. The mounting shaft 72 is installed using a sliding support 32. After installation, the mounting shaft 72 should be perpendicular to the roller mounting plane. During the movement of the cleaning device, the upper and lower guide wheels 71 roll along the upper and lower sides of the solar panel 9 respectively, and the guiding cleaning device moves linearly along the length of the solar panel 9.
[0035] In one exemplary embodiment of this disclosure, such as Figure 3 As shown, the walking assembly 2 includes walking wheels, shock absorber assembly 22, adapter plate 23 and connecting bracket. The shock absorber assembly 22, adapter plate 23 and connecting bracket form an elastic triangular support structure, which can not only provide cushioning, but also make all the walking wheels of the walking assembly 2 evenly contact the surface of the solar panel 9, improve the adhesion of the walking wheels, and evenly distribute the weight of the cleaning device on the four walking wheels to prevent excessive local pressure from damaging the surface of the solar panel 9.
[0036] Furthermore, to improve the flexibility of the cleaning device and considering miniaturization, two or four walking assemblies 2 are self-driven walking assemblies 2. Specifically, the self-driven walking assembly 2 uses the driving wheel 21, and the driven walking assembly 2 uses the driven wheel 28. Since the walking assembly 2 only needs to achieve reciprocating linear movement, and neither the driving wheel 21 nor the driven wheel 28 has steering functionality, any two walking assemblies 2 can be selected as the self-driven walking assembly. (Referring again...) Figures 2-3 The other end of the active connecting bracket 24 of the self-driven walking assembly 2 is integrally formed with a mounting hoop. The active walking wheel 21 is equipped with a drive motor 25, and the hoop on the drive motor 25 is installed in the mounting hoop. The other end of the driven connecting bracket 27 of the driven walking assembly 2 is provided with a support cylinder 26, and the driven walking wheel 28 is rotatably installed on the support cylinder 26.
[0037] In one exemplary embodiment of this disclosure, the cleaning device is provided with at least one tensioning mechanism 8 for tensioning the cleaning track 4, such as... Figure 2 and Figure 5As shown, the tensioning mechanism 8 is located in the middle of the sweeping track 4 and installed in the middle of the track roller seat 3. It includes a mounting plate 81, a mounting bracket 82, an elastic tensioning component 83, and tensioning wheels 84. The mounting plate 81 is bolted to the track roller seat 3. The mounting plate 81, the mounting bracket 82, and the elastic tensioning component 83 form an elastic triangular support structure. One end of the mounting bracket 82 is connected to the mounting plate 81 by a pin, and the other end is a T-shaped structure. Two tensioning wheels 84 are rotatably mounted on the T-shaped structure. Under the elastic support of the elastic triangular support structure, the tensioning wheels 84 press against the inner upper surface of the sweeping track 4 above it, ensuring reliable transmission between the sweeping track 4 and the track roller 6.
[0038] The directional words "up," "down," "side," "end," "middle," "inner," and "outer" mentioned in this article are based on... Figures 1-6 The orientation or positional relationship shown in the corresponding figures, or the orientation relationship in the state of use. These terms are mainly for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated device, element or component to having a particular orientation, or to be constructed and operated in a particular orientation;
