Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic cleaning robots, and in particular to a photovoltaic cleaning module lifting side arm and a mobile side arm cleaning robot. Background Technology

[0002] Some existing photovoltaic cleaning robots include a walking mechanism, a lifting boom, and a brush roller assembly. The lifting boom lifts the brush roller assembly via a traction component, causing the brush roller assembly to press against and adhere to the photovoltaic panel. The walking mechanism drives the boom and brush roller assembly to move, thereby moving the brush roller assembly relative to the photovoltaic panel to clean dust and dirt from the panel.

[0003] Existing lifting booms use winches and traction ropes to lift the cleaning mechanism. The brush roller shaft of the cleaning mechanism is positioned above the photovoltaic panel surface, suspended in mid-air. The brush at the bottom of the roller contacts and deforms against the photovoltaic panel surface, creating pressure for effective cleaning. The weight of the cleaning mechanism is not entirely on the photovoltaic panel, preventing damage. However, when the ground is uneven, the boom's elevation angle changes. When the elevation angle decreases, the entire cleaning mechanism presses against the photovoltaic panel, potentially damaging it. When the elevation angle increases, the brush at the bottom of the roller moves away from the photovoltaic panel surface, reducing or eliminating pressure, making effective cleaning impossible. Therefore, this method is unsuitable for uneven surfaces. Utility Model Content

[0004] The main purpose of this utility model is to provide a lifting side arm for photovoltaic cleaning components and a mobile side arm cleaning robot, which aims to solve the technical problems of the cleaning mechanism damaging the photovoltaic panel when it moves with the mobile side arm cleaning robot and being unable to clean effectively when it leaves the photovoltaic panel.

[0005] To achieve the above objectives, this utility model proposes a lifting arm for a photovoltaic cleaning module, comprising a lifting arm structure, a traction component, and a cleaning mechanism; the traction component includes a winch, a traction rope, a first fixed pulley, a movable pulley, a second fixed pulley, and a balancer; the winch is fixedly mounted on the lifting arm structure, one end of the traction rope is connected to the winch, and the other end of the traction rope sequentially winds around the first fixed pulley, the movable pulley, and the second fixed pulley before being connected to the cleaning mechanism; the movable pulley is slidably mounted on the lifting arm structure, and the balancer is connected to the movable pulley to drive the movable pulley to slide.

[0006] Optionally, the boom structure is equipped with a mounting bracket, the mounting bracket is equipped with a slide rail and a slide block, the movable pulley is mounted on the slide block, the slide block is slidably connected to the slide rail, and the slide block is connected to the hook of the balancer.

[0007] Optionally, the mounting bracket is located in the section of the boom near the bottom, the balancer is located inside the mounting bracket, and the winch is located on the side of the mounting bracket away from the top of the boom.

[0008] Optionally, the slide rail is provided with a limiting groove, the length direction of which is consistent with the length direction of the boom; the slide block is provided with a roller, the roller is set in the limiting groove, the side of the slide block away from the roller is provided with two oppositely spaced side walls, the movable pulley is set between the two side walls, a connecting column is provided between the two side walls, and the hook of the balancer is connected to the connecting column.

[0009] Optionally, the traction assembly is provided in two sets. The traction rope of one set of traction assemblies is connected to one end of the sweeping mechanism along its length, and the traction rope of the other set of traction assemblies is connected to the other end of the sweeping mechanism along its length.

[0010] Optionally, the cleaning mechanism includes a connecting seat and a brush roller assembly. The brush roller assembly includes a cleaning drive unit and a brush roller. The brush roller is rotatably mounted on the connecting seat around its own central axis. The cleaning drive unit is connected to the brush roller in a transmission connection to drive the brush roller to rotate. The cleaning drive unit is located at the bottom of the connecting seat.

[0011] The second aspect of this utility model discloses a mobile side-arm cleaning robot, including a walking mechanism, a frame, and a photovoltaic cleaning component lifting side arm disclosed in the first aspect of this utility model. The frame is mounted on the walking mechanism, and the photovoltaic cleaning component lifting side arm is mounted on the frame.

[0012] The technical solution provided by this utility model can include the following beneficial effects:

[0013] By installing a balancer and a movable pulley between the winch and the cleaning mechanism for compensation, when bumps occur and the elevation angle of the boom structure changes, the balancer provides a certain range of compensation, allowing the cleaning mechanism to maintain its original height, preventing it from pressing down and damaging the photovoltaic panels or leaving the surface of the panels. Specifically, when the elevation angle of the boom structure decreases, the balancer's hook retracts, causing the movable pulley to move and tighten the traction rope, preventing the cleaning mechanism from descending and pressing on the photovoltaic panels, thus reducing the risk of increased pressure and damage to the panels. Conversely, when the elevation angle of the boom structure increases, the cleaning mechanism, due to its own weight, pulls the balancer's hook a certain distance away, preventing the cleaning mechanism from rising due to the increased elevation angle of the boom structure. This ensures that the cleaning mechanism maintains its original pressure on the photovoltaic panels, guaranteeing effective cleaning of the panels.

[0014] Thus, even when the boom structure vibrates due to uneven ground, the cleaning mechanism can still press against the photovoltaic panel with a certain amount of pressure, effectively preventing the photovoltaic panel from being damaged or the cleaning from being ineffective. This makes it suitable for photovoltaic panel cleaning scenarios in the rugged mountainous areas of Northwest China. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0027] The following is combined with Figures 1 to 2 This invention describes a lifting arm for a photovoltaic cleaning module according to an embodiment of the present invention, comprising a lifting arm structure 1, a traction component 2, and a cleaning mechanism 3; the traction component 2 includes a winch 21, a traction rope 22, a first fixed pulley 23, a movable pulley 24, a second fixed pulley 25, and a balancer 26; the winch 21 is fixedly mounted on the lifting arm structure 1, one end of the traction rope 22 is connected to the winch 21, and the other end of the traction rope 22 is sequentially wound around the first fixed pulley 23, the movable pulley 24, and the second fixed pulley 25 before being connected to the cleaning mechanism 3, the movable pulley 24 is slidably mounted on the lifting arm structure 1, and the balancer 26 is connected to the movable pulley 24 to drive the movable pulley 24 to slide.

[0028] By using a balancer 26 and a movable pulley 24 between the winch 21 and the cleaning mechanism 3 for compensation, when bumps occur and the elevation angle of the boom structure 1 changes, the balancer 26 can provide a certain range of compensation, allowing the cleaning mechanism 3 to maintain its original height, preventing it from pressing down and damaging the photovoltaic panel or leaving the surface of the photovoltaic panel. Specifically, when the elevation angle of the boom structure 1 decreases, the hook of the balancer 26 retracts, driving the movable pulley 24 to move and tighten the traction rope 22, preventing the cleaning mechanism 3 from descending and pressing on the photovoltaic panel, thus reducing the risk of damage due to increased pressure on the photovoltaic panel. Conversely, when the elevation angle of the boom structure 1 increases, the cleaning mechanism 3, due to its own weight, pulls the hook of the balancer 26 a certain distance, preventing the cleaning mechanism 3 from rising due to the increased elevation angle of the boom structure 1, thereby maintaining the original pressure on the photovoltaic panel and ensuring effective cleaning of the photovoltaic panel by the cleaning mechanism. Optionally, the balancer 26 is a spring balancer 26.

[0029] Thus, even when the boom structure 1 is bumpy due to uneven ground, the cleaning mechanism 3 can still press against the photovoltaic panel with a certain amount of pressure, which can effectively prevent the photovoltaic panel from being damaged or the cleaning from being ineffective. It is suitable for photovoltaic panel cleaning scenarios in the rugged mountain roads of Northwest China.

[0030] like Figure 3 As shown, the boom structure 1 is equipped with a mounting bracket 11, which has a slide rail 111 and a slide block 113. A movable pulley 24 is mounted on the slide block 113, which is slidably connected to the slide rail 111. The slide block 113 is connected to the hook of the balancer 26. In this way, the movable pulley 24 can be slidably connected to the boom and can slide stably according to the tension of the balancer 26.

[0031] Furthermore, the mounting bracket 11 is located in the section of the boom near the bottom, the balancer 26 is disposed inside the mounting bracket 11, and the winch 21 is located on the side of the mounting bracket 11 away from the top of the boom. In this way, by placing the balancer 26 and the winch 21 in the section of the boom near the bottom, the center of gravity of the photovoltaic cleaning arm is kept as low as possible, thereby improving the stability of the photovoltaic cleaning arm.

[0032] like Figure 4 As shown, the slide rail 111 has a limiting groove 112, the length direction of which is consistent with the length direction of the boom; the slide block 113 has a roller 114, which is disposed within the limiting groove 112; the slide block 113 has two opposing spaced sidewalls 115 on the side away from the roller 114, and a movable pulley 24 is disposed between the two sidewalls 115; a connecting column 116 is disposed between the two sidewalls 115, and the hook of the balancer 26 is connected to the connecting column 116. Thus, the movable pulley 24 slides on the boom under the action of the balancer 26.

[0033] like Figure 2As shown, the traction assembly 2 is provided in two sets. The traction rope 22 of one set of traction assembly 2 is connected to one end of the sweeping mechanism 3 along its length, and the traction rope 22 of the other set of traction assembly 2 is connected to the other end of the sweeping mechanism 3 along its length. Specifically, as... Figure 3 As shown, there are two mounting brackets 11, one above the other. One mounting bracket 11 is located inside the boom, and the other mounting bracket 11 is located on the upper side of the boom.

[0034] More specifically, in one of the traction components 2, the first fixed pulley 23 is located on the lower side of the mounting bracket 11, below the end of the slide rail 111 away from the balancer 26, and the second fixed pulley 25 is located in the section of the boom near the top. In the other traction component 2, the difference is that the second fixed pulley 25 is located in the middle section of the boom.

[0035] Optionally, such as Figure 5 As shown, the cleaning mechanism 3 includes a connecting seat 31 and a brush roller assembly 32. The brush roller assembly 32 includes a cleaning drive unit 321 and a brush roller 322. The brush roller 322 is rotatably mounted on the connecting seat 31 around its own central axis. The cleaning drive unit 321 is connected to the brush roller 322 in a transmission connection to drive the brush roller 322 to rotate. The cleaning drive unit 321 is located at the bottom of the connecting seat 31.

[0036] In some optional embodiments, the cleaning drive unit 321 can be a structure consisting of an electric motor and transmission components such as chains or gears. The electric motor drives the brush roller 322 to rotate on the connecting seat 31 via chains or gears, thereby cleaning the photovoltaic panel. In this embodiment, the cleaning drive unit 321 is located at the bottom of the connecting seat 31, which can lower the center of gravity of the overall cleaning mechanism 3, making the change of the elevation angle of the boom structure 1 or the cleaning mechanism 3 more stable.

[0037] like Figure 6 As shown, the second aspect of this utility model also discloses a mobile side-arm cleaning robot, including a walking mechanism 4, a frame 5, and a photovoltaic cleaning component lifting side arm according to the first aspect of this utility model. The frame 5 is mounted on the walking mechanism 4, and the photovoltaic cleaning component lifting side arm is mounted on the frame 5. The walking mechanism 4 can be a tracked walking mechanism or a wheeled walking mechanism; this utility model does not impose any specific limitations. The photovoltaic cleaning robot of this embodiment has the advantages of the aforementioned photovoltaic cleaning component lifting side arm, and therefore will not be described in detail.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
