Description

Technical Field

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

[0002] Most solar panels are installed on rooftops or in deserts, where they accumulate a lot of dust and dirt over time, affecting their power generation efficiency. Therefore, they need to be cleaned frequently using cleaning equipment.

[0003] In the harsh, windy, and sandy environment of the desert, the service life of cleaning devices is generally reduced. In particular, for cleaning devices with exposed electrical components, the electrical components are prone to failure or even scrapping due to wear and tear from wind and sand. Therefore, the protection of electrical components is especially important.

[0004] like Figure 5 As shown, for the new generation of tracked sweeping device, due to the limitations of the device structure, the electrical components are currently installed on the top, which not only makes the overall structure of the device bulky, but also messy and unsightly. If an electrical component enclosure is added, the total weight of the device will be increased. In addition, the electrical components being located on the top of the device will cause the overall center of gravity of the device to be higher, making it easy to tip over during movement.

[0005] Therefore, in response to the problems existing in the first generation of tracked sweeping devices, a compact solar panel sweeping device was designed to improve the structural problems and performance of the tracked sweeping device.

[0006] 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] The purpose of this disclosure is to provide a compact solar panel cleaning device that overcomes, at least to some extent, one or more problems caused by limitations and defects in related technologies.

[0008] According to one aspect of this disclosure, a compact solar panel cleaning device is provided. The cleaning device includes a cleaning track, two track drive assemblies, and four walking assemblies. The two track drive assemblies are located at both ends of the cleaning track and are used to drive the cleaning track to rotate and clean. The four walking assemblies are distributed in a rectangular array below the cleaning device with the center of gravity of the cleaning device as the center of symmetry. The cleaning device also includes a base shell located in the rotation idle area in the middle of the cleaning track. The four walking assemblies are fixedly connected to both sides of the base shell, and the track drive assemblies are detachably installed at both ends of the base shell.

[0009] The base shell is a hollow structure, and the electrical components are installed in the inner cavity of the base shell and can be put in and taken out through the operating hole at the bottom of the base shell. One end of the base shell is integrally formed with a mounting end plate for bolting a track drive assembly. The control panel is externally mounted on one side of the base shell and is electrically connected to the electrical components.

[0010] In one exemplary embodiment of this disclosure, the cleaning device further includes two tensioning mechanisms, both disposed at the other end of the base shell; the other end of the base shell is integrally formed with two tensioning mounting cylinders, which are symmetrically arranged, and the tensioning mechanisms are installed inside the tensioning mounting cylinders, with their drive ends extending out of the tensioning mounting cylinders and being retractable; the drive ends of the two tensioning mechanisms are bolted to another track drive assembly for jointly driving the track drive assembly to lateral translation.

[0011] In one exemplary embodiment of this disclosure, the tensioning mechanism includes an adjusting sleeve, an adjusting stud, a locking spring, and an adjusting nut. The adjusting sleeve is slidably mounted inside the tensioning mounting cylinder. One end of the adjusting sleeve is bolted to the track drive assembly, and the other end is threaded to the adjusting stud. The operating end of the adjusting stud extends out of the tensioning mounting cylinder and is provided with an adjusting nut. A locking spring is sleeved on the adjusting stud, and the locking spring is compressed between the other end face of the adjusting sleeve and the inner end face of the tensioning mounting cylinder.

[0012] In an exemplary embodiment of this disclosure, the base shell has an elongated oval cross-section, the diameter of the end circle of its cross-section is consistent with the outer diameter of the tensioning mounting cylinder, the tensioning mounting cylinder is disposed on both sides of the base shell along its longitudinal direction, one end of the tensioning mounting cylinder is flush with the other end face of the base shell, both sides of the base shell are recessed to form an operating space located at the other end of the tensioning mounting cylinder, and the adjusting nut is located in the operating space.

[0013] In one exemplary embodiment of this disclosure, the cleaning device further includes a photovoltaic panel, which is mounted on the cleaning track by a support frame. The support frame includes a mounting gantry and horizontal mounting beams. There are at least two mounting gantry, whose two legs are respectively connected to the two sides of the base shell and are mounted across the cleaning track. Two horizontal mounting beams are laid parallel to the longitudinal direction of the base shell at the top of the support frame.

[0014] In an exemplary embodiment of this disclosure, the upper end of the horizontal mounting beam has an adjusting groove, and the bottom of the adjusting groove has a plurality of mounting holes evenly distributed for connection with the mounting frame bolts.

[0025] 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.

[0026] In this example embodiment, a compact solar panel cleaning device is first provided, based on Figure 5 The illustrated first-generation tracked sweeping device structure includes a sweeping track 4, two track drive assemblies 6, and four walking assemblies 5. The two track drive assemblies 6 are located at both ends of the sweeping track 4 and are used to drive the sweeping track 4 to rotate for sweeping. Each drive assembly includes a track roller 61 and a roller mounting plate 62. The four walking assemblies 5 are arranged in a rectangular matrix below the sweeping device, with the center of gravity of the sweeping device as the center of symmetry. Each walking assembly 5 includes a walking wheel and a triangular elastic support structure for mounting the walking wheel. Based on the above-described first-generation tracked sweeping device structure, an improved structure of a compact solar panel sweeping device is described below. Figures 1-4 As shown, it also includes a base shell 3, wherein:

[0027] According to one aspect of this disclosure, the base shell 3 of the cleaning device is installed in the slewing idle area in the middle of the cleaning track 4. The base shell 3 can serve not only as the skeleton of the cleaning device, but also as a protective shell for electrical components, such as... Figure 4 As shown, the base shell 3 is a hollow structure. The electrical components are fixedly connected to the base shell 3 via the mounting plate 36. To facilitate the placement and removal of the electrical components, the bottom of the base shell 3 is provided with an operation hole 33 located in the middle or two symmetrically located on both sides of the center of gravity. The operation hole 33 can be covered with an operation cover. After the electrical components are placed and installed, the operation hole 33 is covered to form a fully enclosed structure. Considering the convenience of electrical control, a control panel 31 is embedded in one side of the base shell 3. The electrical components inside the base shell 3 are led to the embedded structure so that the external control panel 31 can be manually operated.

[0028] The base shell 3 serves as the skeleton, with four walking assemblies 5 connected to both sides of the base shell 3 for support. The track drive assembly 6 is detachably installed at both ends of the base shell 3. For ease of installation, one end of the base shell 3 is integrally formed with a mounting end plate 32 or an integrally formed mounting flange, and one of the track drive assemblies 6 is bolted to the mounting end plate 32 or the mounting flange.

[0029] As a further technical solution of the above exemplary embodiment, the cleaning track 4 needs to be equipped with a tensioning device for tensioning. This can be achieved by integrating the end of the base shell 3 within the vacant area of ​​the rotation, further reducing the overall structural size. (Refer to 2-) Figure 4 The tensioning mechanism 9 adopts a longitudinal (i.e., the rotation direction of the sweeping track 4) telescopic tensioning method. Thus, the roller mounting plate 62 of the other track drive assembly 6 is set at the drive end of the two tensioning mechanisms 9. Under the equal drive of the two tensioning mechanisms 9, the other track drive assembly 6 laterally translates to tension the sweeping track 4. The other end of the base shell 3 is integrally formed with two tensioning mounting cylinders 35. The two tensioning mounting cylinders 35 are symmetrically arranged, and the tensioning mechanism 9 is built into the tensioning mounting cylinders 35.

[0030] The tensioning mechanism 9 can be a telescopic cylinder or a gas spring, or it can adopt the structure shown in this exemplary embodiment. Specifically, for example... Figure 4 As shown, the tensioning mechanism 9 includes an adjusting sleeve 94, an adjusting stud 93, a locking spring 92, and an adjusting nut 91. The tensioning mounting cylinder 35 serves as a guide for the extension and retraction of the adjusting sleeve 94 and has a sliding hole inside. The adjusting sleeve 94 is slidably fitted into the tensioning mounting cylinder 35, with one end extending out of the sliding hole and being secured to the roller mounting plate 62 via a clamping plate 95. The adjusting sleeve 94 has an internal thread, and the adjusting stud 93 is inserted into the other end of the adjusting sleeve 94 and can adjust the total length of the tensioning mechanism 9 through the threaded connection. The operating end of the adjusting stud 93 extends out of the tensioning mounting cylinder 35 and is equipped with an adjusting nut 91 for easy manual operation and tensioning. In addition, to prevent the tensioning mechanism 9 from loosening, a locking spring 92 is fitted on the adjusting stud 93. The locking spring 92 is compressed between the other end face of the adjusting sleeve 94 and the bottom surface of the sliding hole, and the tensioning mechanism 9 achieves self-locking by applying spring force.

[0031] In one exemplary embodiment of this disclosure, in order to improve the structural strength of the base shell 3, making it more integral and aesthetically pleasing, such as Figures 2-3 As shown, the cross-section of the base shell 3 is an elongated oval structure, and the diameter of the end circle of the elongated oval structure cross-section is consistent with the outer diameter of the tensioning mounting cylinder 35. The two sides of the base shell 3 are integrally formed to form the longitudinal tensioning mounting cylinder 35. One end face of the tensioning mounting cylinder 35 is flush with the other end face of the base shell 3. In order to facilitate manual operation of the adjusting nut 91, an operating space 34 is provided at the other end of the tensioning mounting cylinder 35. The operating space 34 is formed by the inward concavity of the two sides of the base shell 3.

[0032] In one exemplary embodiment of this disclosure, in order to achieve further lightweight design and comprehensively consider the power endurance and mass distribution issues of the sweeping device, the sweeping device uses a photovoltaic panel 2 for power supply. The photovoltaic panel 2 is mounted on a support frame above the middle of the sweeping track 4. Referring again... Figure 2 and Figure 3 The support frame includes a mounting gantry 7 and a horizontal mounting beam 8. There are at least two mounting gantry 7s, which are installed side by side at equal intervals on the base shell 3. The two legs of the mounting gantry 7 are fixedly connected to the two sides of the base shell 3 respectively, and are erected across the cleaning track 4. The two horizontal mounting beams 8 are laid parallel to the longitudinal direction of the base shell 3 at the top of the support frame.

[0033] To facilitate the adjustment of the position of the photovoltaic panel 2 so that the structural center of the cleaning device coincides with the center of gravity of the cleaning device, the horizontal mounting beam 8 is a guide rail structure with an adjustment groove 81 at its upper end. A toothed track is provided in the adjustment groove 81. Correspondingly, the frame edge pressure plate 82 includes a pressure hook and a sliding body. The lower end of the sliding body extends into the adjustment groove 81 and is locked on the toothed track. The lower end of the sliding body is provided with a toothed structure that is compatible with the toothed track. After the adjustment is completed, the locking bolts connecting the pressure hook and the sliding body are tightened. The toothed structure meshes with the toothed track to prevent the frame edge pressure plate 82 from moving. The pressure hooks are respectively attached to the side frame surface and the top frame surface of the photovoltaic panel 2 to clamp it, so that the photovoltaic panel 2 is reliably positioned on the horizontal mounting beam 8.

[0034] In addition, to accommodate the installation of the horizontal mounting beam 8 on the mounting gantry 7, the bottom of the adjusting slide 81 has multiple mounting holes evenly distributed, such as... Figure 3 As shown, the horizontal mounting beam 8 is supported by a flexible structure to buffer the wind and impact forces on the photovoltaic panel 2. The top two corners of the gantry body 71 are set as chamfered structures. The buffer connecting plate 72 is an L-shaped thin plate structure, which can deform first when impacted to protect the photovoltaic panel 2. The two ends of the buffer connecting plate 72 are connected to the inclined surfaces of the chamfered structure and form a horizontal top surface for laying and installing the horizontal mounting beam 8. The horizontal top surfaces of all buffer connecting plates 72 should be adjusted to be coplanar to jointly support the photovoltaic panel 2 and keep the photovoltaic panel 2 horizontal.

[0035] The directional words "up," "down," "side," "end," "middle," "inner," and "outer" mentioned in this article are based on...
