[0001] This utility model relates to the field of photovoltaic panel repair, specifically to an auxiliary device for replacing photovoltaic modules. Background Technology

[0002] In recent years, with the rapid development of my country's photovoltaic power generation industry and continuous innovation based on different geographical environments and design concepts, various forms of photovoltaic power stations have emerged, such as mountain photovoltaic, agricultural-photovoltaic complementary, pastoral-photovoltaic complementary, and fishery-photovoltaic complementary systems. However, the complexity of geographical environments makes maintenance work increasingly difficult, especially the replacement of photovoltaic modules. To effectively reduce the difficulty of module replacement and improve work efficiency, a safe and rapid photovoltaic module replacement device suitable for various geographical environments has been developed. Utility Model Content

[0003] This application provides a photovoltaic module replacement auxiliary device, which solves the problem of difficult photovoltaic panel disassembly and assembly, reduces the difficulty of disassembling and assembling photovoltaic panels, and integrates practical daily functions.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution:

[0005] A photovoltaic module replacement auxiliary device includes:

[0006] The vehicle frame consists of a cargo rack and a handrail, with an angle greater than 90 degrees between the cargo rack and the handrail.

[0007] Control components, wherein a pair of control components are detachably connected to the upper surface of the shelf;

[0008] An axle that is detachably connected to a pair of control components;

[0009] The wheels are rotatably connected to both ends of the axle, and the wheels are located on the outside of the frame;

[0010] Guide wheels are detachably connected to the upper surface of each of the armrests, and the axial direction of the guide wheels is perpendicular to the axial direction of the armrest.

[0011] Upper brackets: A pair of upper brackets are provided above the vehicle frame, respectively located above the armrest side;

[0012] The pulleys are detachably connected to the upper bracket;

[0013] The steel cable is connected end to end to form a ring structure. Each wheel is wrapped with a steel cable, and each steel cable also passes around a pulley on the same side as the wheel in the middle. At the same time, the steel cable is guided by a guide wheel.

[0014] Connectors, wherein several connectors are detachably connected to the steel cable.

[0015] The frame consists of a pair of long rods and several short rods. Several short rods are fixed at equal intervals between the pair of long rods. One end of each long rod is bent upward to form a handrail. The unbent part of the long rod and the short rods form a carrying rack. The control component is detachably connected to the upper surface of the long rod.

[0016] The end of the handrail is fixed with a hook.

[0017] The control component includes: a slide, an adjusting rod, a slider, and an axle connecting seat. The slide is fixed to the upper surface of the rack, the slider is slidably connected in the slide, the axle connecting seat is detachably connected to the slider, the axle is detachably connected to the axle connecting seat, one end of the adjusting rod passes through the slide and the other end is rotatably connected to the slider, and the adjusting rod is threadedly connected to the slide.

[0018] The axle connecting seat has an inner sleeve that slides inside it. The outer circumferential surface of the inner sleeve has an outer arc-shaped surface. The axle connecting seat has an inner arc-shaped surface that matches the outer arc-shaped surface. The inner sleeve can swing in an arc shape inside the axle connecting seat through the fit between the outer arc-shaped surface and the inner arc-shaped surface.

[0019] A U-shaped slot is provided on one side of the upper bracket.

[0020] The axle is detachably connected to locking mechanisms at both ends, and a locking sleeve is detachably connected to the outer side of the wheel. The locking mechanisms lock the wheel through the locking sleeve.

[0021] The locking mechanism includes a spring, a connecting screw, a telescopic frame, and a limiting rod. The axle end has a mounting hole. The telescopic frame has a U-shaped structure and a through hole on its bottom surface. One end of the connecting screw passes through the spring and the through hole, extending into the mounting hole and threadedly connecting to the bottom surface of the mounting hole. The telescopic frame and spring are located within the mounting hole, with the spring inside the telescopic frame. The limiting rod is hinged at its center to the top of the telescopic frame and is located within the telescopic frame. The axle end has a pair of locking grooves (one and two) symmetrically formed on its end face. Locking groove two is located at a position where locking groove one is rotated 45 degrees clockwise around the axle's axis. The outer surface of the locking sleeve has several locking grooves equidistantly spaced. The bottom of locking groove one is located outside the locking sleeve, and the bottom of locking groove two is on the same cross-section as the bottom of the locking grooves. The limiting rod can drive the telescopic frame to move outward within the mounting hole. Both ends of the limiting rod engage with either locking groove one or locking groove two.

[0022] The end face of the axle end is symmetrically provided with a locking groove three. The locking groove three is located at the position of the locking groove two rotated 45 degrees clockwise with the axle axis as the center. The vertical distance between the bottom position of the locking groove three and the opening of the locking groove is less than the radius of the limiting rod.

[0023] The beneficial effects of this utility model are: because it uses a frame as the main body and is equipped with a flexible wheel structure, it can travel stably in complex terrains such as mountains, farmland, and fish ponds. It can not only carry photovoltaic modules to be replaced, ladders and tools, but also transport them safely through reasonable load-bearing design, thus solving the problem of inconvenient module handling in complex environments.

[0024] When not in use for changing equipment, the frame can be flipped so that the wheels are in contact with the ground, and the equipment can be used as a regular trolley to transport materials. The frame can also be used as a temporary ladder for workers to climb and work without having to carry multiple additional tools, thus reducing equipment investment costs and improving resource utilization.

[0025] By using wheels, pulleys, and guide wheels in conjunction with steel cables, the photovoltaic modules can be raised, lowered, and moved without the need for manual lifting to higher positions, thus avoiding personal injury or equipment damage caused by modules falling. At the same time, the connectors on the steel cables can firmly fix the photovoltaic modules, further reducing safety hazards during operation.

[0026] Thanks to the locking mechanism, different modes can be used to fully adapt to the braking needs of different usage states, as well as the absence of braking, thereby improving usage efficiency and avoiding the risk of slippage.

[0027] Thanks to the use of hooks and U-shaped slots, it can be quickly fixed to the upper and lower purlins of the photovoltaic bracket, making it compatible with various types of photovoltaic power stations such as mountain photovoltaic, agricultural photovoltaic, and pastoral photovoltaic. In addition, some components (such as pulleys, connectors, and locking sleeves) can be disassembled and replaced, which facilitates later maintenance and upgrades and extends the service life of the device.

Detailed Implementation

[0037] Example 1:

[0038] Reference Figure 1-2 This is a structural schematic diagram of Embodiment 1 of the present invention, a photovoltaic module replacement auxiliary device, comprising:

[0039] The frame 1 is composed of a cargo rack 2 and a handrail 3, and the cargo rack 2 and the handrail 3 have an angle greater than 90 degrees between them.

[0040] Control components, a pair of control components are detachably connected to the upper surface of the shelf 2;

[0041] Axle 4, which is detachably connected to a pair of control components;

[0042] Wheel 5, the two ends of the axle 4 are respectively rotatably connected to the wheel 5, and the wheel 5 is located on the outside of the frame 1;

[0043] Guide wheel 6, each of the upper surfaces of the handrail 3 can be detachably connected to the guide wheel 6, the axis of the guide wheel 6 is perpendicular to the axis of the handrail 3;

[0044] Upper bracket 7: A pair of upper brackets 7 are provided above the frame 1, respectively located above the side of the armrest 3;

[0045] The pulley 8 can be detachably connected to the upper bracket 7;

[0046] The steel cable 9 is connected end to end to form a ring structure. Each wheel 5 is equipped with a steel cable 9, and the middle of each steel cable 9 is also wrapped around a pulley 8 on the same side as the wheel 5. At the same time, the steel cable 9 is guided by a guide wheel 6.

[0047] Connector 10, several connectors 10 can be detachably connected to the steel cable 9.

[0048] In actual use: The end of the handlebar 3 of the frame is attached to the lower purlin of the photovoltaic panel frame, causing the frame 1 to tilt. Simultaneously, the other end of the carrying rack 2 is placed on the ground. Then, the upper bracket 7 is installed on the upper purlin of the photovoltaic panel frame, with the pulley 8 positioned above the upper purlin. The steel cable 9 is then looped onto the wheel 5, and the pulley 8 and guide wheel 6 on the side of the wheel 5 are simultaneously looped into the steel cable 9. The axle 4 is then moved via the control component, causing the wheel 5 to move accordingly. The steel cable 9 is thus taut due to the displacement of the wheel 5. On wheels 5 and pulleys 8, guide wheels 6 simultaneously reverse the direction of steel cable 9, preventing it from contacting the lower purlin. Then, connector 10 temporarily connects the photovoltaic panel and steel cable 9. Next, the connection between the photovoltaic panel and the photovoltaic panel frame is released. Then, wheels 5 are rotated to drive steel cable 9, causing the photovoltaic panel to move along with the rotating steel cable 9. The photovoltaic panel is moved onto the frame 1 for easy handling by construction personnel. Similarly, undamaged photovoltaic panels are connected to steel cable 9 on the frame 1, and wheels 5 can then move the photovoltaic panel upwards to the installation position on the photovoltaic panel frame.

[0049] Without any auxiliary installation, flip the frame 1 so that the wheels 5 are in contact with the ground, and hold the handle 3 to replace the trolley for use.

[0050] The connector 10 is a conventional wire clamping component, consisting of two grooved clamps that hold the steel cable 9 in place. The steel cable is then secured by bolts in conjunction with the clamps. One of the clamps has an extended connecting piece that connects to the back of the photovoltaic panel.

[0051] Example 2:

[0052] Reference Figure 1-2 The difference in this embodiment is that the frame 1 consists of a pair of long rods 11 and several short rods 12. Several short rods 12 are fixed at equal intervals between the pair of long rods 11. One end of each long rod 11 is bent upward to form a handrail 3. The remaining part of the long rod 11 and the short rods 12 form a carrying rack 2. The control component is detachably connected to the upper surface of the long rod 11.

[0053] In actual use: When replacing photovoltaic panels, the short pole 12 and the long pole 11 form a ladder, which is convenient for workers to climb. They can also be used to support photovoltaic panels and other items. The upward-curving handrail 3 can reduce the bending of the back when pushing the cart, thereby increasing the convenience of use.

[0054] Example 3:

[0055] Reference Figure 1 The difference in this embodiment is that the end of the handrail 3 is fixed with a hook 13.

[0056] In actual use: By attaching to the lower purlin with the hook 13, the handrail 3 can be prevented from slipping off the lower purlin.

[0057] Example 4:

[0058] Reference Figure 1-3 The difference in this embodiment is that the control component includes: a slide 14, an adjusting rod 15, a slider 16, and an axle connecting seat 17. The slide 14 is fixed to the upper surface of the rack 2. The slider 16 is slidably connected in the slide 14. The axle connecting seat 17 is detachably connected to the slider 16. The axle 4 is detachably connected to the axle connecting seat 17. One end of the adjusting rod 15 passes through the slide 14 and the other end is rotatably connected to the slider 16. The adjusting rod 15 is threadedly connected to the slide 14.

[0059] In actual use: The adjusting rod 15 is threadedly connected to the slide groove 14. When the adjusting rod 15 is screwed in and out, it drives the slider 16 to move. At the same time, the slider 16 drives the axle 4 to move through the axle connecting seat 17, so that the position of the wheel 5 can be adjusted. Since the adjusting rod 15 and the slide groove 14 are threadedly connected, the slider 16 will not move under force when the adjusting rod 15 is not rotated.

[0060] Example 5:

[0061] Reference Figure 3 The difference in this embodiment is that: an inner sleeve 18 is slidably fitted inside the axle connecting seat 17, the outer circumferential surface of the inner sleeve 18 has an outer arc-shaped surface, and an inner arc-shaped surface adapted to the outer arc-shaped surface is opened inside the axle connecting seat 17. The inner sleeve 18 can swing in an arc shape inside the axle connecting seat 17 through the fit between the outer arc-shaped surface and the inner arc-shaped surface.

[0062] In actual use: the inner sleeve 18 allows the axle connecting seat 17 of a pair of control components to adjust the position of the wheels 5 on both sides when tilted, thereby eliminating the problem that a pair of control components need to be adjusted synchronously. This avoids the problem that the adjustment amount on one side is completely controlled by the deformation of the axle 4, thus improving the adjustment and adaptation range under a small range of rotation.

[0063] Example 6:

[0064] Reference Figure 6 The difference in this embodiment is that a U-shaped slot is opened on one side of the upper bracket 7.

[0065] In actual use: The U-shaped slot is inserted into the upper purlin through the opening. When the pulley 8 is pulled by the steel cable 9, it drives the upper bracket 7 to deflect, so that the inner side of the U-shaped slot is in close contact with the outer surface of the upper purlin, forming a brake. At the same time, the steel cable 9 is released, making it easy to remove.

[0066] Example 7:

[0067] Reference Figure 1 , Figure 4-5and Figure 7 The difference in this embodiment is that: the two ends of the axle 4 are respectively detachably connected to locking mechanisms, and the outer side of the wheel 5 is detachably connected to a locking sleeve 19. The locking mechanism locks the wheel 5 through the locking sleeve 19.

[0068] The locking mechanism includes: a spring 20, a connecting screw 21, a telescopic frame 22, and a limiting rod 23. The axle 4 has a mounting hole at one end. The telescopic frame 22 has a U-shaped structure and a through hole on its bottom surface. One end of the connecting screw 21 passes through the spring 20 and the through hole, extending into the mounting hole and threadedly connecting to the bottom surface of the mounting hole. The telescopic frame 22 and the spring 20 are located within the mounting hole, with the spring 20 located within the telescopic frame 22. The limiting rod 23 is hinged at its center to the top of the telescopic frame 22 and is located within the telescopic frame 22. The end face of the axle 4 is symmetrically provided with a pair of locking grooves 1 25 and a pair of locking grooves 26. The locking grooves 26 are located at the position of locking groove 1 25 rotated 45 degrees clockwise with the axis of the axle 4 as the center. The outer side of the locking sleeve 19 is provided with a number of locking grooves 24 at equal intervals. The bottom of the locking groove 1 25 is located outside the locking sleeve 19. The bottom of the locking groove 26 is located on the same cross section as the bottom of the locking groove 24. The limiting rod 23 can drive the telescopic frame 22 to move outward in the mounting hole. The two ends of the limiting rod 23 are engaged with either a pair of locking grooves 1 25 or a pair of locking grooves 26.

[0069] The end face of the axle 4 is symmetrically provided with a locking groove 3 27. The locking groove 3 27 is located at the position of the locking groove 26 rotated 45 degrees clockwise with the axis of the axle 4 as the center. The vertical distance between the bottom of the locking groove 3 27 and the opening of the locking groove 24 is less than the radius of the limiting rod 23.

[0070] In actual use: In mode one, when the limit rod 23 is located in the lock groove 25, it is in the normal position. At this time, the limit rod 23 is located outside the locking sleeve 19 and does not contact the locking sleeve 19, so that the wheel 5 can rotate without obstruction.

[0071] In mode two, when the limiting rod 23 is located in the second locking groove 26, it is in the locked position. At this time, the limiting rod 23 falls into both the locking groove 24 and the second locking groove 26. By the limiting rod 23 falling into the second locking groove 26, the locking sleeve 19 is restricted from rotating through the locking groove 24, thereby restricting the rotation of the wheel 5.

[0072] In mode three, the limiting rod 23 falls into the locking groove 27, which is a semi-locked state. At this time, the limiting rod 23 falls into the locking groove 27, and part of the limiting rod 23 is located in the locking groove 24. When the wheel 5 rotates, it drives the locking sleeve 19 to rotate. One end of one side of the locking groove 24 contacts the limiting rod 23. Since part of the limiting rod 23 is located in the locking groove 24, it pushes the limiting rod 23, causing the limiting rod 23 to fall into the next locking groove 24, thereby achieving a semi-locked state. This state provides a damping effect.

[0073] To keep the limiting rod 23 always in contact with the first, second, and third locking grooves, a spring 20 is used, which is limited by the connecting screw 21. The spring 20 pushes the bottom of the telescopic frame 22, causing the limiting rod 23 to be tightly attached to the end of the axle 4, thereby preventing the limiting rod 23 from disengaging from the first, second, and third locking grooves.

[0074] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes are within the protection scope of the technology.
