Description

Technical Field

[0001] This disclosure relates to the field of photovoltaic panel cleaning equipment, and more specifically, to a solar panel cleaning device adaptable to various width specifications. Background Technology

[0002] Existing roller-type or rotary brush discs are small in size and flexible in their path, making them suitable for cleaning solar panels of various widths. However, due to their low cleaning efficiency, they tend to pick up and splash dust or sand from the brush bristles into the clean area, resulting in unsatisfactory cleaning effects. This requires repeated cleaning to achieve the desired cleanliness, leading to low efficiency. Furthermore, they are inadequate in removing dust and debris. Common methods for removing dust and debris after cleaning include blowing it away with air and vacuum suction. Blowing away dust can easily generate dust and cause secondary dust accumulation, while vacuum suction often requires cleaning the dust storage chamber. Therefore, using a tracked cleaning device with a width similar to that of solar panels can effectively solve the aforementioned dust removal and high-efficiency cleaning problems.

[0003] However, this limits the adaptability of the solar panel's surface width. Since the existing tracked cleaning device has the same cleaning area as the solar panel, if different specifications of tracked cleaning devices are configured for solar panels of different widths, it will result in insufficient flexibility in cleaning work, excessive equipment investment costs, and the equipment will not be fully utilized. During the process of updating and iterating solar panels, there will be equipment idleness issues.

[0004] Therefore, it is necessary to design a cleaning device that can adapt to various solar panel widths in order 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

[0007] According to one aspect of this disclosure, a solar panel cleaning device adaptable to various width specifications is provided. The cleaning device includes a cleaning track, a frame, four wheel assemblies, and two track rollers. The cleaning track is respectively fitted onto the two track rollers at both ends and driven by the track rollers to rotate along the width direction of the solar panel. The track rollers are disposed at both ends of the frame. The four wheel assemblies jointly support the frame and move along the length direction of the solar panel. The device is characterized by further including four guiding mechanisms and a telescopic mechanism, wherein…

[0008] The telescopic mechanism is set on both sides of the frame, and the guide mechanism is set at the drive end of the telescopic mechanism and is driven by the telescopic mechanism to move horizontally along the width direction of the solar panel. The guide mechanism includes a guide wheel and a support rod. The support rod is connected to the drive end of the telescopic mechanism, and the guide wheel is set at the bottom end of the support rod. Four guide mechanisms are set in pairs at both ends of the frame, and their guide wheels roll against the long frame sides of the solar panel respectively.

[0009] The two traveling wheel assemblies located on the same side of the frame are swivel wheel sets.

[0010] In one exemplary embodiment of this disclosure, there are two telescopic mechanisms, which adopt a stepping double-head electric push rod structure. The push rod includes a push rod motor, a guide rod sleeve, and a combined rod. A support seat is fixedly provided on the side of the frame. The push rod motor and the combined rod are supported by the support seat. The combined rod is disposed through the guide rod sleeve and is driven by the push rod motor and guided by the guide rod sleeve to perform linear double-head stepping telescopic extension and retraction. Two guide mechanisms on the same side of the frame are respectively disposed at the two ends of the combined rod.

[0011] In one exemplary embodiment of this disclosure, the combined rod includes two push rods, an adjusting screw sleeve, and an adjusting rod sleeve. The adjusting rod sleeve cooperates with the guide rod sleeve. Adjusting holes are symmetrically arranged at both ends of the adjusting rod sleeve. The adjusting screw sleeve is rotatably disposed at the opening of the adjusting hole. One end of each of the two push rods is telescopically disposed in the adjusting hole and threadedly connected to the adjusting screw sleeve. A locking spring is disposed in the adjusting hole. One end of the locking spring is connected to the bottom surface of the adjusting hole, and the other end is pressed by one end face of the push rod. A guide mechanism is disposed at the other end of the push rod.

[0012] In one exemplary embodiment of this disclosure, the push rod includes a square rod section and an adjusting section. The adjusting section is threadedly engaged with an adjusting screw sleeve. Roller mounting plates are detachably fixed at both ends of the frame. A square hole is provided on the roller mounting plate or the frame. The square rod section passes through the square hole and slides in the square hole.

[0013] In one exemplary embodiment of this disclosure, a quick-connector is further included for connecting two or more cleaning devices arranged in a linear "I" configuration in series; in the combined cleaning state,

[0014] The outermost two sweeping devices are equipped with guide mechanisms at their outermost ends to guide their movement. The guide mechanisms are connected to the drive end of the telescopic mechanism via quick-change joints.

[0015] Replace the guide mechanisms on the two adjacent ends of the adjacent cleaning devices with quick-connect parts for series connection. The quick-connect parts are connected to the drive end of the telescopic mechanism through quick-change joints.

[0017] In one exemplary embodiment of this disclosure, a female quick-connect fitting is provided at the end of each telescopic mechanism perpendicular to its telescopic direction, and at least two quick-connect fittings are provided at the end of each telescopic mechanism.

[0018] In one exemplary embodiment of this disclosure, the two ends of the guide wheel are formed by protrusions on its wheel surface to form two limiting edge edges, which are respectively used to limit the upper and lower guide wheels of the long frame of the solar panel.

[0019] An exemplary embodiment of this disclosure discloses a solar panel cleaning device adaptable to various width specifications. A telescopic mechanism drives a guide mechanism to move laterally, adapting to the width of the solar panel. Simultaneously, while maintaining the guide mechanism's position, it combines lateral adjustment with the omnidirectional wheel assembly. The telescopic mechanism can also adjust the cleaning position of the cleaning track on the solar panel, ensuring that the multi-pass cleaning area of ​​the cleaning track can completely cover solar panels of various width specifications. Therefore, this cleaning device can adapt to the guiding movement and full-area cleaning of solar panels of various width specifications. Furthermore, this cleaning device not only transports dust to the side of the solar panel for removal during the cleaning process, but also completes the full-area cleaning of the solar panel in only a limited number of passes, resulting in high cleaning efficiency.

[0026] 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.

[0027] In this example embodiment, a solar panel cleaning device adaptable to various width specifications is first provided; Reference Figures 1-2 As shown, the cleaning device includes a cleaning track 2, a frame 6, four sets of five walking wheels, and two track rollers 10. The frame 6 has roller mounting plates 9 at both ends for mounting the track rollers 10. The cleaning track 2 is respectively fitted over the two track rollers 10 at both ends and is driven by the track rollers 10 to rotate along the width direction of the solar panel 1. The four sets of five walking wheels are evenly distributed on both sides of the cleaning track 2 to jointly support the frame 6. The two sets of five walking wheels or the four sets of five walking wheels located on one side of the frame 6 are the drive wheels, which are self-driven along the length direction of the solar panel 1.

[0028] According to one aspect of this disclosure, a solar panel cleaning device adaptable to various width specifications is provided. In order to adapt to various width specifications, on the one hand, the telescopic mechanism 8 drives the guide mechanism 4 to extend and retract to adapt to the width of the solar panel 1; on the other hand, the guide mechanism 4 is used to guide and limit the two sides, and the telescopic mechanism 8 is used to adjust the cleaning position of the cleaning track 2 on the solar panel 1.

[0029] Specifically, refer again Figure 2 Four guide mechanisms 4 are arranged in pairs at both ends of the frame 6. Each guide mechanism includes a guide wheel 42 and a support rod 41. The support rod 41 is connected to the drive end of the telescopic mechanism 8. The guide wheel 42 is located at the bottom end of the support rod 41. Its wheel surface rolls against the sides of the long frame of the solar panel 1. The telescopic mechanism 8 drives the guide mechanism 4 to move laterally to extend and retract, so as to adapt to the width of the solar panel 1. In addition, the telescopic mechanism 8 connected to the two guide mechanisms 4 at one end of the frame 6 can be extended by utilizing the limiting effect of the two sides of the long frame 6, and the telescopic mechanism 8 connected to the two guide mechanisms 4 at the other end of the frame 6 can be shortened. In the state where the guide wheel 42 is in rolling contact with the sides of the long frame 6, since the two walking wheel sets 5 located on the same side of the frame 6 are universal wheel sets, under the action of the telescopic lateral force, the cleaning device automatically adjusts the cleaning area of ​​the cleaning track 2 on the solar panel 1 when it moves along the length direction of the solar panel 1.

[0030] In one exemplary embodiment of this disclosure, the telescopic mechanism 8 is fixedly disposed on both sides of the frame 6. Four independent telescopic mechanisms 8 can be provided, each independently driving one of the four guide mechanisms 4 to move laterally. However, considering the lightweighting and synchronization accuracy issues of the cleaning device, this embodiment preferentially uses two telescopic mechanisms 8 for telescopic drive. The power device of the telescopic mechanism 8 adopts the existing technology of a stepper double-headed electric push rod 83 device, which can achieve an equal amount of retraction on the other side while one side extends. (See again...) Figure 2 It includes a push rod motor 81, a guide rod sleeve 86, and a combined rod. Several connecting blocks 84 are respectively set on both sides of the frame 6. The push rod motor 81 and the combined rod are supported by a support base 85 to ensure the horizontality of the combined rod. The push rod motor 81 and the guide rod sleeve 86 are an integral finished structure, which is set in the middle of the frame 6. The combined rod is set through the guide rod sleeve 86. Under the drive of the push rod motor 81 and the limiting guidance of the guide rod sleeve 86, the two ends of the combined rod are moved and extended by the two ends of the guide rod sleeve 86 in equal amounts. Since the total length of the combined rod remains unchanged, the frame 6 is translated along the width direction of the combined rod, adjusting the cleaning position of the cleaning track 2 on the solar panel 1. In this way, at most, two reciprocating cleaning is required along the length direction of the solar panel 1, and the cleaning area of ​​the cleaning device can completely cover the solar panel 1.

[0031] In one exemplary embodiment of this disclosure, in order to adjust the total length of the combined rod to accommodate the width of the solar panel 1, such as... Figure 2 and Figure 3 As shown, the combined rod includes two push rods 83, adjusting screw sleeves 87, and adjusting rod sleeves 82. The adjusting rod sleeves 82 are inserted through the guide rod sleeves 86. Adjusting screw sleeves 87 are provided at both ends of the adjusting rod sleeves 82. The adjusting screw sleeves 87 are rotatable screw sleeves with internal threads. Their joint ends are fixedly connected to the adjusting holes of the adjusting rod sleeves 82. The push rods 83 are threadedly connected to the adjusting screw sleeves 87, and one end of the push rods 83 can slide and extend within the adjusting holes. The extension length of the push rods 83 can be adjusted by manually rotating the adjusting screw sleeves 87. In order to lock the length of the combined rod after adjustment, a locking spring 88 is provided in the adjusting holes. The locking spring 88 is pressed between the bottom surface of the adjusting holes and one end face of the push rods 83. A connecting block 84 is fixed to the other end of the push rods 83 for installing the guide mechanism 4 or the quick connector 7.

[0032] In one exemplary embodiment of this disclosure, in order to automatically prevent rotation of the push rod 83 during adjustment of the rotating adjusting screw sleeve 87, as follows: Figure 2As shown, the push rod 83 includes a square rod section 831 and an adjusting section. The adjusting section has an external thread on its outer circumference, which is threaded into the adjusting sleeve 87. In coordination with the square rod section 831, according to the telescopic structure parameters, square holes can be opened on the two end plates of the roller mounting plate 9 used to install the track roller 10, or a guide plate with a square hole can be set on the frame 6. The square rod section 831 passes through the square hole and slides in coordination with the square hole.

[0033] In an exemplary embodiment of this disclosure, if a solar panel 1 with a large width cannot be adapted by adjusting the telescopic mechanism 8, then two or more cleaning devices are arranged in a linear “I” line and connected in series to form a joint cleaning device, so as to complete the full-area cleaning of the solar panel 1 with the highest efficiency within the minimum stroke.

[0034] The combined sweeping device only requires the guide mechanisms 4 at the outermost two ends for guidance. Correspondingly, the guide mechanisms 4 are only set at the outermost ends of the two outermost sweeping devices. In order to facilitate the disassembly of the remaining guide mechanisms 4, quick-change connectors 3 are used to connect the guide mechanisms 4 and the drive ends of the telescopic mechanism 8.

[0035] At the same time, the quick-change connector 3 at the end of the telescopic mechanism 8 is fully utilized to connect the cleaning devices in series. The two adjacent ends of the adjacent cleaning devices are connected in series by the quick connector 7. The quick connector 7 is connected in series by the quick-change connector 3 at the end of the telescopic mechanism 8.

[0036] Therefore, male quick-connectors 3 are provided at both ends of the quick connector 7 and the upper end of the support rod 41, and female quick-connectors 3 are provided on the connecting block 84 at the end of the telescopic mechanism 8.

[0037] Since the quick-connector 3 is not subjected to axial tension, the female head of the quick-connector 3 is provided on the connecting block 84 perpendicular to the telescopic direction of the telescopic mechanism 8. In addition, in order to constrain the rotational freedom of the guide mechanism 4 around the quick-connector 3, at least two quick-connectors 3 are provided at the end of each telescopic mechanism 8.

[0038] In an exemplary embodiment of this disclosure, in order to prevent the guide wheel 42 from detaching from the long frame of the solar panel 1, the two ends of the guide wheel 42 are formed by protrusions on its wheel surface to form two limiting edges, which are engaged between the upper and lower edges of the long frame of the solar panel 1.

[0039] The directional words "up," "down," "side," "end," "middle," "inner," and "outer" mentioned in this article are based on... Figures 1-3The orientation or positional relationship shown in the corresponding figures, or the orientation relationship in the state of use.
