Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel disassembly and assembly technology, and in particular to a photovoltaic panel disassembly and assembly robot. Background Technology

[0002] In large-scale photovoltaic power plants, photovoltaic modules frequently fail for various reasons. Maintenance personnel must promptly replace damaged modules to ensure uninterrupted power generation efficiency. Currently, module replacement relies primarily on manual labor. Maintenance personnel must first disconnect the module's wiring and remove the bolts securing it to the support frame. During this process, another worker typically holds the damaged module to prevent it from slipping off the inclined support after the bolts are removed. Similarly, when installing a new module, one worker pushes it upwards along the inclined support to its installation position and adjusts its position, while another worker secures the bolts. This replacement method requires at least two workers, and because the modules are usually located at a high position, the steps of removing and placing the modules are both dangerous and physically demanding, making the entire replacement process cumbersome and time-consuming. Utility Model Content

[0003] The main purpose of this invention is to propose a photovoltaic panel disassembly and assembly robot, which aims to reduce operational risks and improve replacement efficiency.

[0004] To achieve the above objectives, the photovoltaic panel disassembly and assembly robot proposed in this utility model includes:

[0005] Mobile mechanism;

The support platform is located on the side of the rotating component away from the lifting platform and is connected to the rotating shaft. A limiting component is provided on the top of the support platform, which divides the support platform into a front support section and a rear support section. The limiting component is spaced apart from the support platform and is used to stop the photovoltaic panels when the support platform rotates.

[0008] In one embodiment, there are two rotating shafts, and one end of the supporting platform is provided with two extension arms that extend upward to connect with the rotating shafts.

[0009] In one embodiment, the supporting platform is provided with stop side plates on both sides.

[0011] In one embodiment, a stop is provided at one end of the movable plate, the photovoltaic panel abuts against the stop, and an electric push rod is provided at the top of the rear support section. The telescopic shaft of the electric push rod is connected to the stop and is used to drive the movable plate to move.

[0012] In one embodiment, the stop member has a clearance ramp at its top.

[0013] In one embodiment, the inner wall of the stop side plate is provided with a guide wheel, which is located near the connection between the front support section and the rear support section.

[0026] 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.

If the specific posture changes, the directional indicators will also change accordingly.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, 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. If 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.

[0029] In existing technologies, replacing photovoltaic (PV) panels in large-scale photovoltaic (PV) power plants relies on a two-person collaborative model. Maintenance personnel must remove bolts and support the PV panels on inclined support frames. Due to the high installation position of the PV modules, there is a risk of falls during the operation, and manually supporting the panels is physically demanding. Traditional methods also rely on manual labor to control panel slippage, requiring repeated trial and error for angle adjustments, thus limiting work efficiency due to limitations in manual operation precision and physical strength.

[0030] To solve this technical problem, this utility model provides a photovoltaic panel disassembly and assembly robot 1000, which includes:

[0031] Mobile mechanism 1;

[0032] Lifting mechanism 2 is located on top of moving mechanism 1, and lifting mechanism 2 includes lifting platform 21;

[0033] The supporting mechanism 3 includes a rotating component 31 and a supporting platform 32. The rotating component 31 is located on the top side of the lifting platform 21 and has a rotating shaft 311. The supporting platform 32 is located on the side of the rotating component 31 away from the lifting platform 21 and is connected to the rotating shaft 311. The top of the supporting platform 32 is provided with a limiting component 33, which divides the supporting platform 32 into a front supporting section 323 and a rear supporting section 324. The limiting component 33 is spaced apart from the supporting platform 32 and is used to stop the photovoltaic panel 2000 when the supporting platform 32 rotates.

[0034] The mobile mechanism 1 refers to a chassis structure with autonomous movement capabilities, which can be implemented using a tracked or wheeled chassis. The direction and position are controlled by a drive motor, solving the position adjustment problem during the transport of the photovoltaic panel 2000. The lifting mechanism 2 is a mechanical device capable of vertical height adjustment, which can be a scissor lift or hydraulic cylinder driven structure. The lifting platform 21 supports the supporting mechanism 3, enabling precise adjustment of the working height. The rotating component 31 is a mechanical connection device for angle adjustment, which can be a hinge mechanism driven by a servo motor. The rotating shaft 311 drives the supporting platform 32 to adjust its pitch angle. The limiting component 33 is a mechanical structure that dynamically blocks the photovoltaic panel 2000, which can be a retractable baffle or a spring reset device. During the rotation of the supporting platform 32, it creates a gap between the supporting platform 32 and the platform surface, preventing the photovoltaic panel 2000 from sliding off the supporting surface due to inertia.

[0035] Specifically, during operation, the moving mechanism 1 positions the robot below the target photovoltaic panel 2000, and the lifting mechanism 2 drives the support platform 32 to rise until it is flush with the bottom surface of the photovoltaic panel 2000. The rotating component 31 drives the support platform 32 to rotate to match the tilt angle of the photovoltaic panel 2000, so that the front support section 323 fits against the bottom of the photovoltaic panel 2000. After the fixing bolts are removed, the photovoltaic panel 2000 slides along the tilted support platform 32 under the action of gravity. The limiting component 33 automatically rises during the platform rotation, constraining the sliding path of the photovoltaic panel 2000 to the rear support section 324 through the gap. After disassembly is completed, the support platform 32 rotates back to a vertical position, and the lifting mechanism 2 descends to a safe height, allowing the operator to complete the removal of the old panel and the loading of the new panel by one person. During installation, the support platform 32 rotates in the opposite direction to the angle of the photovoltaic bracket 331.

[0036] Compared to existing technologies, the traditional two-person collaborative mode is integrated into mechanical linkage operation, and manual support is replaced by the angle adjustment of the rotating shaft 311 and the dynamic constraint of the limiting component 33. The problem of uncontrollable sliding path of photovoltaic panel 2000 in existing technologies is transformed into directional sliding by the gap control of the limiting component 33, and the angle adaptation process is transformed from manual trial and error to mechanical servo control. The risk of fall in existing operations is eliminated by the height adjustment function of the lifting platform 21, and operators can complete high-altitude operations without climbing the support frame 331.

[0037] Through the above technical solution, this application achieves safe installation and removal of photovoltaic panels 2000 under single-person operation conditions, eliminating the need for manual support while ensuring controllable panel sliding path. The synergistic effect of the rotating component 31 and the lifting mechanism 2 enables precise matching of the installation and removal angles of the photovoltaic panels 2000, and the dynamic constraint mechanism of the limiting component 33 effectively prevents accidental panel slippage. This solution transforms traditional two-person high-altitude operations into ground-based mechanical operations, significantly reducing operational risks and improving replacement efficiency.

[0038] Please refer to Figure 1 and Figure 2 In one embodiment of this utility model, there are two rotating shafts 311, and one end of the supporting platform 32 is provided with two extension arms 321, which extend upward to connect with the rotating shafts 311.

[0039] The fact that there are two rotating shafts 311 indicates that a dual-axis symmetrically distributed support structure is adopted. Specifically, cylindrical metal shafts can be arranged parallel to each other on both sides of the lifting platform 21 and connected to the extension arm 321 through bearings. The dual-axis structure forms symmetrical fulcrums, which evenly distribute the weight of the photovoltaic panel 2000 during rotation and avoids platform tilting caused by torque imbalance when supported by a single axis.

[0040] Please refer to Figure 2 In one embodiment of this utility model, the supporting platform 32 is provided with stop side plates 322 on both sides.

[0041] The stop side plate 322 refers to a vertical limiting structure symmetrically distributed along the length of the supporting platform 32. It can be fixed to both sides of the platform by welding or bolting, and its height can be set to exceed half the thickness of the photovoltaic panel 2000. This structure forms a continuous guiding boundary through rigid contact on both sides, continuously constraining lateral displacement during the movement of the photovoltaic panel 2000.

[0042] Please refer to Figure 2 In one embodiment of the present invention, a movable plate 34 is slidably provided on the top of the front support section 323. The movable plate 34 protrudes from the top surface of the support platform 32 and can be moved from the front support section 323 to the rear support section 324.

[0043] The sliding configuration refers to the use of a guide rail and slider mechanism on the top surface of the front support section 323. This can be achieved using a combination of linear guide rails and ball-bearing sliders, allowing the moving plate 34 to move smoothly along the length of the support platform 32. The moving plate 34 protruding above the top surface of the support platform 32 means that it forms a limiting protrusion vertically above the surface of the support platform 32. The ability of the moving plate 34 to move from the front support section 323 to the rear support section 324 means that the sliding stroke of the moving plate 34 covers the working area from the front to the rear of the support platform 32. This can be achieved by using limit switches to control the movement range, ensuring the smooth transfer of the photovoltaic panel 2000 from the disassembly position to the installation position.

[0044] Compared to existing technologies, replacing traditional photovoltaic panels 2000 requires manual pushing by operators along the inclined support 331, which poses a risk of slippage and is physically demanding. This solution, by incorporating a sliding movable plate 34 mechanism, transforms the movement of the photovoltaic panel 2000 into a mechanically driven process. Operators only need to control the equipment to adjust the position of the photovoltaic panel 2000, eliminating the operational risks of manual contact with the inclined photovoltaic panel 2000 and reducing labor intensity.

[0045] Please refer to Figure 2 In one embodiment of the present invention, a stop 35 is provided at one end of the movable plate 34, the photovoltaic panel 2000 abuts against the stop 35, and an electric push rod 36 is provided at the top of the supporting rear section 324. The telescopic shaft of the electric push rod 36 is connected to the stop 35 and is used to drive the movable plate 34 to move.

[0046] The movable plate 34 is a plate-like structure that slides on top of the supporting front section 323, protruding from the top surface of the supporting platform 32 to form a movable support surface. It can be implemented as a metal plate with sliding rails and is used to support and push the photovoltaic panel 2000. The stop 35 is a blocking structure located at the end of the movable plate 34, which can be implemented as an L-shaped metal plate or a protruding block, and is used to limit the positional deviation of the photovoltaic panel 2000 during movement. The electric push rod 36 is an actuator that achieves linear reciprocating motion driven by a motor. It can be implemented as an electric telescopic rod with a displacement sensor, used to precisely control the stroke and pushing speed of the movable plate 34. The cooperative structure of the stop 35 and the movable plate 34 prevents the photovoltaic panel 2000 from sliding directly to the bottom of the supporting platform 32 due to its own weight during disassembly, thus avoiding impact damage.

[0047] Please refer to Figure 2 In one embodiment of this utility model, the top of the stop member 35 is provided with a clearance slope.

[0048] Please refer to Figure 2In one embodiment of the present invention, the inner sidewall of the stop side plate 322 is provided with a guide wheel 37, which is located near the connection between the front section 323 and the rear section 324.

[0049] The guide wheel 37 refers to a rolling component installed inside the stop side plate 322. It can be implemented using a bearing structure or a pulley structure, reducing frictional resistance during the movement of the photovoltaic panel 2000 through rolling contact. The stop side plate 322 refers to a plate-like structure vertically fixed to both sides of the support platform 32. It can be implemented using lightweight alloy plates and is used to limit the lateral movement range of the photovoltaic panel 2000. The area near the connection point refers to the adjacent position between the front and rear sections of the support platform 32. Specifically, it can be positioned within 5 to 10 centimeters of the boundary line to cover the critical area where the photovoltaic panel 2000 contacts the side wall during rotation.

[0050] Specifically, when the photovoltaic panel 2000 moves on the support platform 32 or rotates with the platform, its side will contact the inner wall of the stop side plate 322. The guide wheel 37 replaces the original sliding friction with rolling, significantly reducing the moving resistance of the photovoltaic panel 2000. When the support platform 32 rotates around the rotation axis 311, the photovoltaic panel 2000 may have a lateral displacement tendency due to gravity. The rolling guiding effect of the guide wheel 37 can counteract this displacement force, allowing the photovoltaic panel 2000 to smoothly transition between the front and rear connection areas along a preset trajectory. The position layout of the guide wheel 37 is targeted at the area where the photovoltaic panel 2000 has the greatest contact pressure with the side wall during rotation, ensuring continuous guiding function during dynamic adjustment.

[0051] The arrangement of the guide wheel 37 in the key rotation area further optimizes the motion trajectory control of the photovoltaic panel 2000, preventing lateral deviation during dynamic adjustment and ensuring continuous and smooth disassembly and assembly operations.

[0052] Please refer to Figure 2 In one embodiment of the present invention, the inner wall of the stop side plate 322 is provided with a guide wedge 38, which is located on the side of the guide wheel 37 away from the supporting rear section 324.

[0053] When the photovoltaic panel 2000 moves from the front support section 323 to the rear support section 324, the positional deviation of the photovoltaic panel 2000 caused by various reasons is corrected to ensure that the photovoltaic panel 2000 is in the predetermined position in the rear support section 324.

[0054] Please refer to Figure 2 In one embodiment of this utility model, the limiting component 33 includes:

[0055] Bracket 331 is fixed to the two stop side plates 322;

[0056] The movable limit plate 332 is slidably set below the bracket 331. A spring 333 is provided between the movable limit plate 332 and the bracket 331. The movable limit plate 332 is used to stop the photovoltaic panel 2000 from falling when the supporting platform 32 rotates.

[0057] A movable limiting plate 332 is provided. When the photovoltaic panel 2000 moves, the bottom of the movable limiting plate 332 abuts against the top of the photovoltaic panel 2000. The movable limiting plate 332 prevents the photovoltaic panel 2000 from detaching from the supporting platform 32 due to changes in angle. A spring 333 is provided to absorb part of the offset force of the photovoltaic panel 2000, preventing damage caused by collision between the photovoltaic panel 2000 and the movable limiting plate 332 due to hard contact.

[0058] Please refer to Figure 2 In one embodiment of this utility model, the movable limiting plate 332 is provided with guide slopes on both sides.

[0059] With this configuration, when the photovoltaic panel 2000 enters the rear support section 324, it avoids collision with the side of the movable limiting plate 332 due to the end being raised.

[0060] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
