Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic maintenance devices, in particular to a photovoltaic cleaning robot with a snow removal function and a snow removal module component. Background Art

[0002] When snow accumulates on the surface of the photovoltaic panel, it is necessary to remove the snow from the surface of the photovoltaic panel. The current photovoltaic cleaning robots mainly use roller brushes to clean the surface of the photovoltaic panel without an integrated snow removal function. For example, a solar panel surface automatic brushing cleaning device disclosed in a Chinese invention patent application with publication number CN113441444A cannot work when snow accumulates.

[0003] At present, for clearing the accumulated snow, it is necessary to integrate a snow removal device on the photovoltaic panel. Some are electric snow melting solutions, and some are mechanical processing solutions. For example, the mechanical processing solution discloses an automatic snow removal device for photovoltaic panels in high-cold areas as disclosed in the Chinese invention patent application with publication number CN115483883A. However, no matter which one is used, it is not flexible enough to use, increases the structural complexity and weight of the photovoltaic panel, and has low practicality. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and propose a photovoltaic cleaning robot with a snow removal function. The robot is flexible to use and simplifies the structural complexity and weight of the photovoltaic panel compared to the prior art, making it more practical. A snow removal module assembly is also proposed, which can be used for the photovoltaic cleaning robot.

[0005] Compared with the prior art, the utility model proposes a photovoltaic cleaning robot with a snow removal function, including a frame, walking rollers and a cleaning member, the frame is used to be straddled on the photovoltaic panel, the walking rollers are connected to the frame, the walking rollers are used to drive the frame to move through the photovoltaic panel, the cleaning member is connected to the frame, the cleaning member is located on the upper side of the photovoltaic panel and is used to clean the photovoltaic panel, and also includes a snow removal component arranged on the front and / or rear side of the frame, the snow removal component includes a support arm arranged along the span direction of the frame, the support arm is suspended at the front and / or rear side of the frame, the part of the support arm suspended outside is connected to a scraper member, and also includes a drive unit, the drive unit is transmission-connected to the scraper member, the drive unit drives the scraper member to move along the support arm to remove snow.

[0006] After adopting the above structure, compared with the prior art, the utility model has the following advantages:

[0007] The present invention is improved by arranging snow removal components on the front and / or rear sides of the frame, and the overall movement of the snow removal components is achieved through the self-propelled movement of the frame, while the specific snow removal is carried out by using a scraper, thereby simplifying the structure and being flexible to use. Compared with the prior art, the structural complexity and weight of the photovoltaic panel are simplified, and the practicality is higher.

[0008] In addition, since the scraper is provided, the cleaning principle is to move along the support arm to remove snow. Therefore, in addition to being used for snow removal, in an environment where the dust environment is relatively serious, the scheme of the present invention can also first clean the dust on the photovoltaic panel, and then further clean it with a cleaning piece, which is beneficial to improve the cleaning efficiency. Therefore, the use of the scheme of the present invention is also beneficial to realize the aforementioned cleaning scheme, that is, to provide the hardware foundation of the aforementioned cleaning scheme.

[0009] Therefore, in the present disclosure, the so-called snow removal is just a general term, not just snow removal, and the expression "snow removal function" is not an absolute limitation on the protection scope of the present disclosure.

[0010] Compared with the prior art, the utility model also proposes a snow removal module assembly, which serves as a snow removal assembly of a photovoltaic cleaning robot, and includes a suspension bracket and a support arm. One end of the suspension bracket is detachably connected to a frame, and the other end of the suspension bracket is connected to the support arm.

The drive unit can be removed / installed from the frame together with the snow removal module assembly. The drive unit is transmission-connected to the scraper member, and the drive unit drives the scraper member to move along the support arm to remove snow.

[0011] After adopting the above structure, compared with the prior art, the utility model has the following advantages:

[0012] The present invention improves the snow removal component by making it modular. When snow removal is needed, the snow removal module component can be installed on a frame to form a photovoltaic cleaning robot with snow removal function.

DETAILED DESCRIPTION

[0029] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are for example only, and those skilled in the art may think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0030] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0031] like Figures 1 to 7 The figure shows a snow removal component 5 and a photovoltaic cleaning robot with a snow removal function, wherein the photovoltaic cleaning robot with a snow removal function comprises a frame 1, a walking roller 2 and a cleaning member 3, the frame 1 is used to be straddled on a photovoltaic panel 4, the walking roller 2 is connected to the frame 1, the walking roller 2 is used to drive the frame 1 to move past the photovoltaic panel 4, the cleaning member 3 is connected to the frame 1, the cleaning member 3 is located on the upper side of the photovoltaic panel 4 and is used to clean the photovoltaic panel 4, the cleaning member 33 is such as a rotating roller brush, the rotating roller brush rotates for cleaning, and also includes a snow removal component 5 arranged on the front and / or rear side of the frame 1, the snow removal component 5 includes a support arm 6 arranged along the span direction of the frame 1, the support arm 6 is suspended on the front and / or rear side of the frame 1, the part of the support arm 6 suspended outside is connected to a scraper member 7, and also includes a drive unit 8, the drive unit 8 is transmission-connected to the scraper member 7, the drive unit 8 drives the scraper member 7 to move along the support arm 6 to remove snow.

[0032] like Figure 6 , 7As shown, the photovoltaic cleaning robot moves by itself driven by the walking roller 2, and at the same time the driving unit 8 drives the scraper 7 to move along the support arm 6 to remove snow, and the guide edge wheel 21 of the photovoltaic cleaning robot provides certain guidance, so that the photovoltaic cleaning robot is not easy to deviate when walking by itself.

[0033] Preferably, the drive unit 8 adopts a planetary gear reduction motor. In this way, the output shaft or the output end of the planetary gear reduction motor has been decelerated, and the torque has been amplified, so the planetary gear reduction motor only needs to be matched with a motor with a smaller power. In addition, the structure and control of the planetary gear reduction motor are also relatively mature, and the existing technology can be used.

[0034] The driving unit 8 is connected to the scraper member 7 by a belt drive, a chain drive, a screw drive, etc. Any other driving unit 8 and the driving connection between the driving unit 8 and the scraper member 7 applicable to the present disclosure can also be applied to the present disclosure.

[0035] In some embodiments, Figure 2 , 3 As shown in Figures 4 and 5, the lower side of the support arm 6 is connected with a sliding seat 13, the sliding seat 13 is connected to the scraper member 7, and the sliding seat 13 is connected to the support arm 6 in a sliding and guiding manner. In this way, on the one hand, it is beneficial to provide good support and guide movement for the scraper member 7, and on the other hand, during maintenance, it is not necessary to dismantle the sliding seat 13, and the sliding seat 13 is connected to the driving unit 8 in a transmission manner, so that the disassembly and assembly of the scraper member 7 avoids the influence on the transmission connection.

[0036] In some embodiments, Figure 1 , 2 As shown in Figures 3, 6 and 7, the snow removal component 5 is modularly designed and is designed as a snow removal module component, which includes a suspension bracket 14 and a support arm 6. One end of the suspension bracket 14 is detachably connected to the frame 1, and the other end of the suspension bracket 14 is connected to the support arm 6. The support arm 6 is suspended at the front and / or rear side of the frame 1 through the suspension bracket 14; the part of the support arm 6 suspended outside is connected to a scraper member 7, and the suspension bracket 14 or the support arm 6 is provided with a drive unit 8, which can be removed / installed from the frame 1 together with the snow removal module assembly, and the drive unit 8 is transmission-connected to the scraper member 7, and the drive unit 8 drives the scraper member 7 to move along the support arm 6 to remove snow.

[0037] In this example, if Figure 3As shown, the drive unit 8 is installed in a suspension bracket 14. When the suspension bracket 14 is removed / installed from the frame 1, the drive unit 8 is removed / installed together. That is to say, the drive unit 8 is always connected to the snow removal module assembly. The drive unit 8 and the transmission connection structure between the drive unit 8 and the scraper member 7 do not need to be disassembled and assembled due to the disassembly / installation of the snow removal module assembly and the frame 1, which greatly simplifies the on-site disassembly and assembly problems.

[0038] The driving unit 8 of the snow removal module assembly can be powered by itself, or it can be powered by the power supply on the frame 1, and both are acceptable. Of course, in order to simplify the structure and weight, it is preferred to power the power supply on the frame 1.

[0039] In some embodiments, a quick disassembly structure is also included, which includes the suspension bracket 14 and a connecting seat 15 located on the frame 1, and the suspension bracket 14 is quickly disassembled and connected to the connecting seat 15. In this way, the snow removal module assembly can be disassembled and assembled more conveniently.

[0040] In some embodiments, Figure 1 , 6 As shown, the connection seat 15 is configured as a slot portion 16 , and the suspension bracket 14 and the slot portion 16 are connected by plugging to achieve quick assembly and disassembly.

[0041] Furthermore, in order to facilitate fixation, the slot portion 16 is provided with a pluggable fixing pin 18, and correspondingly, a corresponding fixing hole 19 is provided on the connecting seat 15. After the suspension bracket 14 is plugged into the slot portion 16, the fixing pin 18 is reinserted into the fixing hole 19 for fixation. When disassembly is required, the fixing pin 18 can be pulled out in reverse, and the snow removal module assembly can be removed.

[0042] In some embodiments, Figure 2 , 6 As shown, the suspension bracket 14 is provided at both ends of the support arm 6, and the suspension bracket 14 is provided with a handle 17, and the user lifts / lowers the entire snow removal module assembly through the handle 17. This further facilitates the user to disassemble and move the snow removal module assembly, especially for the use scenario of the photovoltaic panel 4 with a large span, and in a snowy environment, the design has great practicality for the convenience and safety of the user.

[0043] In order to better meet the cleaning requirements of the photovoltaic panel 4, improve the cleaning efficiency and protect the photovoltaic panel 4, the present disclosure also makes additional designs for the scraper member 7, which are specifically described as follows:

[0044] like Figure 3 , 4As shown, the scraper member 7 includes a hard scraper 9 and a soft scraper 10, and the hard scraper 9 and the soft scraper 10 are connected in sequence up and down. In this way, the soft scraper 10 is on the side close to the photovoltaic panel 4. When the snow is thick, the hard scraper 9 and the soft scraper 10 are used to remove the snow together. Since the hard scraper 9 is not easy to deform, the force for snow removal is guaranteed and the snow removal efficiency is improved. When the snow is thin, the soft scraper 10 is used to remove the snow. Since the snow is thin, the snow can also be removed quickly.

[0045] Furthermore, the hard scraper 9 and the soft scraper 10 are movably connected so as to be movable up and down. When the soft scraper 10 pushes against the photovoltaic panel 4, the soft scraper 10 can be pushed upward. In this way, if the photovoltaic panel 4 is already dirty before being covered with snow, even if there is large adhered dirt, when the scraper member 7 encounters the dirt that is difficult to remove immediately, it can avoid scratching the surface of the photovoltaic panel 4 due to insufficient deformation of the soft scraper 10, thereby making the scraper member 7 have better adaptability and greatly improving the reliability of the use of the scraper member 7.

[0046] Preferably, Figure 3 , 4 As shown in Figure 5, the lower end of the hard scraper 9 is provided with a U-shaped groove 11 with an opening at the lower end and arranged in the up-down direction, the upper end of the soft scraper 10 is movably matched with the U-shaped groove 11, and a waist-shaped hole 12 is provided on the groove wall of the U-shaped groove 11. The bolt 20 passes through the waist-shaped hole 12 and the soft scraper 10 in sequence so that the soft scraper 10 is movably installed in the U-shaped groove 11. The bolt 20 cooperates with the waist-shaped hole 12, and the bolt 20 can move up and down along the waist-shaped hole 12 with the soft scraper 10, and the waist-shaped hole 12 constitutes a limit to the up-down movement of the soft scraper 10. In this way, not only the purpose of active connection is achieved, but also the structure is simple, and it is convenient for disassembly and maintenance.

[0047] The above mainly exemplifies how modular design can realize snow removal module components and photovoltaic cleaning robots with snow removal functions. Of course, it is not limited to modular design. The snow removal components 5 can also be integrated on the photovoltaic cleaning robot to form a photovoltaic cleaning robot with snow removal functions, but the integrated solution is set to be non-detachable.

[0048] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0049] The above description is only an illustrative embodiment of the present invention, so any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
