Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module handling technology, and in particular to a photovoltaic module handling device. Background Technology

[0002] Photovoltaic modules (also called solar panels) are the core and most important part of a solar power generation system. The function of photovoltaic modules is to convert solar energy into electrical energy and send it to batteries for storage or to power loads.

[0003] The handling of photovoltaic (PV) modules is a crucial step in PV installation. The most common method is manual handling, where workers lift and drag the modules onto a transport device, which then moves them to the designated location. Existing transport devices fall into two categories: one stacks PV modules horizontally on the vehicle body, and the other arranges them vertically. The horizontal stacking method is more prevalent due to its convenience. Vehicles used for horizontal stacking are equipped with limiting mechanisms to restrict the position of the PV modules and prevent them from slipping off the vehicle during transport.

[0004] Existing handling devices for horizontally stacked photovoltaic modules typically use a side-blocking structure as their limiting mechanism. This structure surrounds the photovoltaic modules and limits their movement. The side-blocking structure is fixed in position and can only accommodate photovoltaic modules of a single size, resulting in poor overall adaptability. Furthermore, the device is low in height, requiring workers to bend over significantly when unloading the bottom photovoltaic modules (especially the very bottom ones) from the handling device, leading to high workload. Utility Model Content

[0005] To address the technical problem in the background art that existing handling devices for horizontally stacked photovoltaic modules have fixed edge structure positions, can only adapt to photovoltaic modules of a single size, and have poor overall adaptability, this utility model provides a photovoltaic module handling device.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a photovoltaic module handling device, including a vehicle body with handrails and wheels. Several guide grooves are formed on the vehicle body, arranged diagonally along the vehicle body. Each guide groove is slidably connected to a limiting unit, which is vertically positioned. A drive adjustment assembly is provided on the vehicle body, connected to all the limiting units, for driving the limiting units to move along the guide grooves. The diagonally arranged guide grooves, in conjunction with the limiting units, can be flexibly adjusted according to the size of the photovoltaic modules, adapting to the handling needs of photovoltaic modules of different specifications and improving the versatility of the handling device.

[0008] Preferably, the drive adjustment assembly includes a drive rod, with a corresponding drive rod in each guide groove, and the limiting unit is provided with a first mounting hole connected to the drive rod, so that the limiting unit can move stably along the guide groove.

[0009] Preferably, the vehicle body is equipped with a pedal, which is connected to all drive units through a drive adjustment component. The transport personnel can drive the limit unit by stepping on the pedal, freeing their hands and making it easier to operate the photovoltaic modules at the same time during the transport process, thus improving the convenience and safety of the transport.

[0010] Preferably, the drive adjustment assembly includes two connecting plates, which are slidably connected to the vehicle body. Each connecting plate is movably connected to two drive units on the same side. The two connecting plates are respectively hinged to drive plates via a first link and a second link. The drive plates are rotatably mounted on the vehicle body and are hinged to the pedal. The limiting unit is also slidably connected to the drive rod. A spring for self-resetting of the limiting unit is sleeved on the drive rod. The structure of the multi-link and connecting plates can effectively transmit the pedal's stepping action to each limiting unit, realizing synchronous drive of all limiting units. The spring setting allows the limiting unit to automatically reset when no external force is applied, which facilitates the clamping and limiting of photovoltaic modules and the protection of edges and corners, enhancing the automation level and ease of use of the device.

[0011] Preferably, the connecting plate is provided with a second mounting hole, which is an elongated hole structure. The bottom of the limiting unit is fixedly provided with a connecting part, which is inserted into the second mounting hole. This allows the limiting unit to have a certain range of motion during movement, which can better adapt to the movement trajectory of the limiting unit in the guide groove. It also facilitates the connection and installation of the limiting unit and the connecting plate, and improves the stability and reliability of the structure.

[0012] Preferably, the drive rod is a screw structure, and the drive rod is threadedly connected to the limiting unit. One end of the drive rod extends outward from the vehicle body and is fixedly provided with a hand-tightening part. The outer wall of the limiting unit is fixedly provided with a limiting part that cooperates with the guide groove. The screw structure drive rod is threadedly connected to the limiting unit, which makes the adjustment accuracy higher. The handling personnel can precisely control the position of the limiting unit by rotating the hand-tightening part. The limiting part cooperates with the guide groove to prevent the limiting unit from shifting or shaking during movement, and ensure the stability of the handling process.

[0013] Preferably, a limiting groove is provided on one side of the limiting unit. The limiting groove extends along the axial direction of the limiting unit. The limiting groove is a V-shaped groove, which can better fit the corners of the photovoltaic module, provide a more stable limiting effect, prevent the photovoltaic module from slipping during transportation, and improve the safety of transportation. At the same time, the V-shaped groove extends along the axial direction of the limiting unit, which can adapt to photovoltaic modules of different thicknesses and different layers.

[0014] Preferably, a guide hole is provided at the center of the vehicle body, and an elastic support component is slidably provided in the guide hole, which can assist manual handling, reduce the bending degree of workers, and effectively reduce labor intensity.

[0015] Preferably, the elastic support component includes a plate-shaped support part, with a guide part fixedly connected to the bottom of the support part. The guide hole has a stepped hole structure, and the guide part is slidably disposed in the guide hole. A spring is sleeved on the guide part. When multiple photovoltaic modules are horizontally stacked on the vehicle body, the support part can be used to support the photovoltaic modules. At the same time, the photovoltaic modules push the support part downward to move, thereby compressing the spring. When the photovoltaic modules are moved downward, the weight decreases after the next photovoltaic module is removed, and the spring pushes the support part and the photovoltaic modules above it to move upward, thereby assisting manual handling, reducing the bending degree of workers, and effectively reducing labor intensity.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are:

[0017] 1. The vehicle body is equipped with a drive adjustment component, which is connected to all the limit units and is used to drive the limit units to move along the guide groove. The guide groove, which is set along the diagonal, works with the limit units and can be flexibly adjusted according to the size of the photovoltaic modules to meet the handling needs of photovoltaic modules of different specifications and improve the versatility of the handling device.

[0018] 2. The structure of multi-link and connecting plate can effectively transmit the pedal stepping action to each limit unit, realize the synchronous drive of all limit units, and the spring setting enables the limit unit to automatically reset when no external force is applied, which facilitates the clamping and limiting of photovoltaic modules and the protection of the corners, and enhances the automation level and ease of use of the device.

[0019] 3. An elastic support component is installed at the center of the vehicle body. When multiple photovoltaic modules are stacked horizontally on the vehicle body, the support component can support the photovoltaic modules. At the same time, the photovoltaic modules push the support component downward to compress the spring. When the photovoltaic modules are moved downward, the weight decreases after the next photovoltaic module is removed. The spring pushes the support component and the photovoltaic modules above it to move upward, thereby assisting manual handling, reducing the bending degree of workers, and effectively reducing labor intensity.

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0030] Example 1

[0031] In a typical embodiment of this utility model, such as Figure 1As shown, a photovoltaic module handling device is proposed, including: a vehicle body 1, a handrail 2, wheels 3, guide grooves 4, limiting units 5, and a drive adjustment component 6. The vehicle body 1 has a plate-like structure, and several wheels 3 are installed at the bottom of the vehicle body 1. The wheels 3 are omnidirectional wheels, and brake plates and brake pads are installed on the sides of the wheels 3, which can realize the movement and stationary position of the handling device, facilitating the loading and unloading of photovoltaic modules. The handrail 2 is fixedly installed on one side of the vehicle body 1, so that the staff can push the entire handling device to move by hand. There are four guide grooves 4, which are arranged along the diagonal of the vehicle body 1 on the upper surface of the vehicle body 1. There are four limiting units 5, which are arranged vertically to limit and protect the corners of the photovoltaic modules. Each guide groove 4 has a corresponding limiting unit 5 that is slidably connected to it.

[0032] The drive adjustment assembly includes four drive rods 15, which are horizontally positioned. Each guide groove 4 contains one drive rod 15 for rotational movement. Specifically, as shown... Figure 3 As shown, in this embodiment, the drive rod 15 is a screw structure with external threads. The axis of the drive rod 15 is parallel to the guide groove 4. The drive rod 15 is rotatably mounted in the guide groove 4 through a bearing, and one end of the drive rod 15 extends outward from the vehicle body 1 to form a hand-tightening part 16. The extended end of the drive rod 15 is used for manual tightening. The limiting unit 5 is threadedly connected to the drive rod 15. During the rotation of the drive rod 15 around the axis, it can drive the limiting unit 5 to move along the corresponding guide groove 4, thereby realizing the adjustment of the position of the limiting unit 5 to meet the limiting requirements of photovoltaic modules of different specifications.

[0033] like Figure 2 As shown, the limiting unit 5 is a columnar structure. A limiting groove 11 is opened on one side of the limiting unit 5. The limiting groove 11 is vertically arranged and extends along the axial direction of the limiting unit 5. The limiting groove 11 is a V-shaped groove, which is used to engage with the corners of the photovoltaic module, thereby limiting and protecting the corners of the photovoltaic module. In order to further improve its protection capability, a buffer layer can also be set in the limiting groove 11. The buffer layer can be a rubber layer, etc., to reduce the collision damage between the corners of the photovoltaic module and the limiting unit 5.

[0034] The limiting unit 5 is provided with a first mounting hole 14. In this embodiment, the first mounting hole 14 is a threaded hole structure with internal threads for threaded connection with the drive rod 15. A limiting part 12 is fixedly provided on the outer wall of the limiting unit 5. The limiting part 12 is a protruding structure. A corresponding groove structure is provided in the guide groove 4, thereby realizing the snap-fit ​​limiting with the limiting unit 5. While ensuring that the limiting unit 5 moves along the guide groove 4, the limiting unit 5 is prevented from being pulled out of the guide groove 4.

[0035] A guide hole 9 is provided at the center of the vehicle body 1. An elastic support assembly is slidably disposed in the guide hole 9. The elastic support assembly includes a support part 7, a guide part 8, and a spring 10. The support part 7 is a plate-shaped structure, and the guide part 8 is a columnar structure. The support part 7 is fixedly disposed on the top of the guide part 8 by welding or other means. The guide hole 9 is a stepped hole structure. The upper diameter of the guide hole 9 is larger than its lower diameter. The size of the support part 7 is larger than the lower diameter of the guide hole 9 and smaller than the upper diameter of the guide hole 9. The guide part 8 is slidably disposed in the guide hole 9. The spring 10 is sleeved on the guide part 8. One end of the spring 10 is fixedly connected to the guide hole 9, and the other end of the spring 10 is fixedly connected to the bottom of the support part 7.

[0036] The support part 7 can be used to support and lift the photovoltaic modules. Specifically, when multiple photovoltaic modules are stacked horizontally on the vehicle body 1, the support part 7 can be used to support the photovoltaic modules. At the same time, the photovoltaic modules push the support part 7 downward to compress the spring 10. When the photovoltaic modules are moved downward, the weight decreases after the next photovoltaic module is removed, and the spring 10 pushes the support part 7 and the photovoltaic modules above it to move upward, thereby assisting manual handling, reducing the bending degree of workers, and effectively reducing labor intensity.

[0037] It is understandable that the specific dimensions of the support part 7 can be selected according to the actual design requirements. There are no specific restrictions here, as long as the support part 7 can effectively support the photovoltaic module.

[0038] Example 2

[0039] In a typical embodiment of this utility model, such as Figure 1 As shown, a photovoltaic module handling device is proposed, including: a vehicle body 1, a handrail 2, wheels 3, guide grooves 4, limiting units 5, and a drive adjustment component 6. The vehicle body 1 has a plate-like structure, and several wheels 3 are installed at the bottom of the vehicle body 1. The wheels 3 are omnidirectional wheels, and brake plates and brake pads are installed on the sides of the wheels 3, which can realize the movement and stationary position of the handling device, facilitating the loading and unloading of photovoltaic modules. The handrail 2 is fixedly installed on one side of the vehicle body 1, so that the staff can push the entire handling device to move by hand. There are four guide grooves 4, which are arranged along the diagonal of the vehicle body 1 on the upper surface of the vehicle body 1. There are four limiting units 5, which are arranged vertically to limit and protect the corners of the photovoltaic modules. Each guide groove 4 has a corresponding limiting unit 5 that is slidably connected to it.

[0040] The drive adjustment assembly includes four drive rods 15, which are horizontally arranged. Each guide groove 4 contains one drive rod 15. In this embodiment, the drive rod 15 is a smooth rod structure, with its axis parallel to the guide groove 4. The drive rod 15 is fixedly installed within the guide groove 4. Figure 5As shown, the limiting unit 5 is a columnar structure. A limiting groove 11 is provided on one side of the limiting unit 5. The limiting groove 11 is vertically arranged and extends along the axial direction of the limiting unit 5. The limiting groove 11 is a V-shaped groove, which is used to engage with the corners of the photovoltaic module, thereby limiting and protecting the corners of the photovoltaic module. A first mounting hole 14 is provided on the limiting unit 5. In this embodiment, the first mounting hole 14 is a through hole structure, which is used to slide with the drive rod 15 of the light rod structure, thereby playing a guiding and limiting role.

[0041] Understandably, in order to further improve its protective capabilities, a buffer layer can be set in the limiting groove 11. The buffer layer can be a rubber layer or the like, to reduce the collision damage between the corners of the photovoltaic module and the limiting unit 5.

[0042] In this embodiment, the bottom of the limiting unit 5 is also fixedly provided with a connecting part 13. The connecting part 13 extends downward into the guide groove 4 and is connected to the foot pedal type drive adjustment component 6 so as to control the action of the limiting unit 5 by foot pedal.

[0043] like Figure 4 As shown, the foot-operated drive adjustment assembly 6 includes a connecting plate 17, a first connecting rod 19, a second connecting rod 20, and a drive plate 22. Two connecting plates 17 are provided, each movably connected to two drive units 5 on the same side, as detailed below. Figure 6 As shown, the connecting plate 17 has a second mounting hole 18, which is an elongated hole structure. The connecting part 13 at the bottom of the limiting unit 5 is inserted into the second mounting hole 18. Both connecting plates 17 are slidably disposed at the bottom of the vehicle body 1. The drive plate 22 is rotatably disposed on the vehicle body 1 via a rotating shaft. The drive plate 22 has a first connecting hole 23, a second connecting hole 24, a third connecting hole 25, and a fourth connecting hole 26. The first connecting hole 23 and the second connecting hole 24 are arranged vertically, with the first connecting hole 23 located above the second connecting hole 24. The first connecting hole 23 is hinged to one connecting plate 17 via a first connecting rod 19. The second connecting hole 24 is hinged to another connecting plate 17 via a second connecting rod 20. The third connecting hole 25 is used to rotatably connect to the vehicle body 1 via a rotating shaft. The fourth connecting hole 26 is close to the second connecting hole 24 and is used to hinge to the pedal 21 on the vehicle body 1.

[0044] The first link 19 and the second link 20 have different lengths. In this embodiment, the first link 19 is used to connect with the connecting plate 17 on the two limiting units 5 near the pedal 21. Therefore, the length of the first link 19 is shorter than that of the second link 20.

[0045] In this embodiment, a spring 10 is also sleeved on the drive rod 15. One end of the spring 10 is fixedly connected to the guide groove 4, and the other end of the spring 10 is fixedly connected to the side wall of the limiting unit 5 away from the limiting groove 11. In actual use, when the pedal 21 is pressed, the pedal 21 drives the drive plate 22 to rotate around the axis, so that the upper end of the drive plate 22 moves toward the pedal 21, and then pulls the two limiting units 5 toward the pedal 21 through the first connecting rod 19 and the connecting plate 17. At the same time, the lower end of the drive plate 22 moves away from the pedal 21, and then pushes the other two limiting units 5 toward the pedal 21 through the second connecting rod 20. That is, the four limiting units 5 move toward the direction away from the center of the vehicle body 1 at the same time, and compress the spring 10 on the drive rod 15 to increase the distance between adjacent limiting units 5. After the pedal 21 is released, the four limiting units 5 move toward the center of the vehicle body 1 under the action of the spring 10 to clamp the photovoltaic module, so as to adapt to photovoltaic modules of different sizes.

[0046] In this embodiment, an elastic support component is also provided at the center of the vehicle body 1 to assist manual handling, reduce the bending degree of workers, and effectively reduce labor intensity.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
