Description

Technical Field

[0001] The present application relates to the technical field of maintenance equipment, and in particular to a maintenance platform. Background Art

[0002] The performance and life of photovoltaic power plants and related equipment are significantly affected by outdoor environmental factors. Because they are usually located in open-air environments, natural conditions such as temperature fluctuations, wind, precipitation, and dust accumulation affect the efficiency and durability of photovoltaic panels. Regular inspection and maintenance can promptly detect and solve problems, such as cleaning dust, inspecting and replacing damaged parts, to ensure efficient and stable operation of the photovoltaic system. For photovoltaic equipment in high places or in inaccessible areas, the use of stable and safe inspection platforms helps protect the safety of maintenance personnel. And convenient inspection platforms can reduce the time and labor required to reach and repair photovoltaic equipment, improving overall maintenance efficiency.

[0003] Existing PV panel maintenance usually includes two main methods: ground maintenance and high-altitude maintenance. For ground-mounted PV panels, maintenance is relatively simple, and workers can directly access the PV panels for cleaning and inspection. This method usually does not require complex equipment. In contrast, for PV panels installed on roofs, mountains or other difficult-to-access locations, maintenance work is more complicated. In such cases, traditional high-altitude maintenance platforms are generally composed of fixed brackets, equipped with a basic work surface and a simple lifting mechanism. These platforms need to be manually adjusted in height and position to achieve the required working height. These traditional maintenance platforms can meet the basic needs of high-altitude operations to a certain extent.

[0004] However, due to its large size, the traditional maintenance platform has many inconveniences in transportation and movement. This large structure limits its flexibility and adaptability in actual operation, especially when it needs to be moved frequently or used in multiple locations. Based on this, there is an urgent need for a maintenance platform that can solve the technical problems of the traditional maintenance platform being large in size and inconvenient to transport. Utility Model Content

[0030] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0031] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0032] In the prior art, photovoltaic panel maintenance platforms are usually integrated structures, which requires larger physical space and additional labor input during handling and transportation. Many traditional platforms lack the ability to be folded or disassembled, which means that they take up a lot of space when not in use and are not convenient for storage or use in compact environments. In addition, the fixed structure of these platforms limits their flexible movement between different sites, especially when the work site needs to be frequently transferred. This inconvenience is particularly prominent. In addition, these traditional platforms are usually designed to be fixed or have cumbersome installation processes in terms of safety measures, such as the configuration and installation of guardrails, which not only prolongs the preparation time, but may also affect their application efficiency and safety in the working environment to a certain extent.

[0033] In view of the above technical problems, the utility model provides an inspection platform. The inspection platform can be adjusted within a wider range of heights through a lifting assembly to meet the needs of variable terrain. At the same time, the expansion board is stored through a sliding mechanism when it is not needed. This sliding connection allows the expansion board to be quickly unfolded to increase the working area, or compactly folded to reduce the volume of the platform. In the stored state, the expansion board is close to the operating platform, reducing the space occupied by the entire platform, making the platform more convenient for storage and transportation. In addition, the foldable extension board enhances the adaptability of the platform. When unfolded, the contact area between the base and the ground is increased, providing the platform with stronger stability and support. When not in use, these extension boards can be easily folded and stored, reducing the required storage space and facilitating the transportation of the platform. Furthermore, the quick-installation and clamping setting of the guardrail can be quickly and safely connected to the operating platform and the expansion board, effectively reducing the installation time and improving the overall safety. Through this quick loading and unloading mechanism, the platform is more efficient when frequently changing the working position, and the complexity of construction and disassembly is also reduced.

[0034] In terms of application scenarios, the maintenance platform of the present application can enhance the flexibility and transportation convenience of the platform to adapt to changing terrain and working environments. To this end, this maintenance platform is suitable for photovoltaic power plants or any occasions that require high-altitude operations. For example, in photovoltaic power plants, workers need to regularly inspect and maintain high-altitude solar panels. In such an environment, traditional fixed or inflexible work platforms often cannot provide sufficient safety or adapt to the unevenness of the ground. In addition, the maintenance platform is also suitable for maintenance work in industrial facilities, large buildings and bridges. Its flexibly adjustable height and expanded workspace provide advantages in these scenarios, and the maintenance platform is easier to transport and store when not in use. It can not only ensure the safety of operators, but also improve work efficiency and comfort.

[0035] In order to make the above-mentioned purposes, features and advantages of the embodiments of the utility model more obvious and easy to understand, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0036] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0037] like Figures 1 to 7As shown, the utility model provides a maintenance platform, which focuses on achieving flexibility, stability and easy storage and transportation. The maintenance platform includes an operating platform 13, a base 11 and a lifting assembly 15 arranged on the base 11. The driving end of the lifting assembly 15 is connected to the bottom surface of the operating platform 13, so that the operating platform 13 can be adjusted vertically according to the required working height. The maintenance platform can adapt to the maintenance of photovoltaic panels at different heights, thereby greatly improving the adaptability and efficiency in a changing operating environment. Preferably, the lifting assembly 15 includes four hydraulic struts 151, and the four hydraulic struts 151 are evenly arranged. That is, the hydraulic struts 151 are evenly distributed at the four corners of the platform base 11. This layout ensures the stability and balance of the operating platform 13 during the lifting process, especially under uneven load or uneven ground conditions. Each hydraulic telescopic device can work independently, so that the user can control the height of each corner of the platform to adapt to the changing working environment and needs. The hydraulic struts 151 can be adjusted quickly and smoothly within a wide range of heights, thereby providing great flexibility for maintenance work at different heights. Secondly, the hydraulic mechanism can provide greater load-bearing capacity and stability compared to traditional mechanical lifting systems. In addition, the hydraulic support 151 is usually equipped with a safety locking mechanism to prevent accidental descent or accidental movement during maintenance.

[0038] In order to expand the working area and accommodate more maintenance personnel, two expansion plates 14 are symmetrically arranged on both sides of the operating platform 13, and the expansion plates 14 are slidably connected to the operating platform 13 through a separation component, providing a convenient way to quickly deploy and store when in use. That is, the expansion plate 14 can be overlapped with the operating platform 13 when not in use. Preferably, the expansion plate 14 and the operating platform 13 are stacked from top to bottom, and this stacked structure enables the expansion plate 14 to be located above the operating platform 13 when not in use, so as not to occupy additional space. When a wider working area is needed, the expansion plate 14 can slide and unfold smoothly with the top surface of the operating platform 13 through a separation component. The bottom surface of the expansion plate 14 is slidably connected to the top surface of the operating platform 13 through a separation component, and the end of the expansion plate 14 extends downward and covers the operating platform 13. The structural integrity and stability of the entire maintenance platform are increased, and the durability of the maintenance platform is improved. The separation assembly includes a slide 172 and a slider 171. The slide 172 is arranged on the front and rear end surfaces of the operating platform 13, and the slider 171 is arranged on the extended inner wall of the expansion plate 14, and the slider 171 is slidably connected to the slide 172. In this way, the expansion plate 14 can slide smoothly along the operating platform 13, making the maintenance platform not only suitable for various high-altitude working scenes, but also easy to adjust according to specific tasks, providing operators with a safe, spacious and easy-to-operate working environment.

[0039] Furthermore, in order to increase the stability of the expansion board when it is unfolded and to realize the automatic unfolding of the expansion board, the separation component also includes a hydraulic telescopic rod 173. One end of the hydraulic telescopic rod 173 is connected to the end of the operating platform, and the other end is connected to the inner side wall of the expansion board. This allows the expansion board to have a support in the direction of extension when it is unfolded, further ensuring the stability of the expansion board. Preferably, when the telescopic support rod is engaged with the engaging groove 141, the telescopic support rod is inclined, and at this time, an outward force is also applied to the expansion platform to further ensure the stability of the expansion board when it is unfolded.

[0040] The end of the expansion board 14 away from the operating platform 13 is connected to the telescopic support rod 16, and is arranged horizontally through the telescopic support rod 16. The setting of the expansion board 14 not only increases the working space, but also enhances its stability through the horizontal arrangement of the telescopic support rod 16. When the expansion board 14 slides out from the operating platform 13, they can achieve a stable horizontal setting through the support of the telescopic support rod 16, ensuring safety and comfort during the operation. The bottom surface of the expansion board 14 is provided with a plurality of snap-in grooves 141, one end of the telescopic support rod 16 is connected to the base 11, and the other end is snap-in with the snap-in groove 141 of the expansion board 14. It should be noted here that in addition to being connected to the base 11, the telescopic support rod 16 can also be connected to the extension board 12. The operator can flexibly choose the specific connection method according to specific needs, and its main purpose is to support the expansion board 14. The clamping groove 141 allows one end of the telescopic support rod 16 to be firmly connected to the expansion board 14, and the other end to be connected to the base 11 (or the extension board 12), thereby ensuring its stability and reliability when the expansion board 14 is fully unfolded. The addition of this clamping mechanism improves the overall stability and flexibility of the operating platform 13. The maintenance platform not only meets the diverse work needs in terms of function, but also provides great convenience in operation, ensuring an efficient and safe working environment.

[0041] Further, the telescopic support rod 16 includes at least one inner rod 161 and at least one outer rod 162. The outer rod 162 is slidably mounted from the lower end of the inner rod 161 to the outer side of the inner rod 161. In order to ensure the stability and safety of the telescopic support rod 16 during use, the inner rod 161 is provided with a push-type elastic buckle 1611. To match this, the outer rod 162 is provided with at least two limiting holes 1621 corresponding to the push-type elastic buckle 1611. The limiting holes 1621 and the push-type elastic buckle 1611 are limited by clamping, and the sliding extension and contraction of the outer rod 162 are limited. Such push-type elastic buckle 1611 and limiting hole 1621 not only ensure the stability and safety in use, but also improve the convenience and efficiency of operation. Preferably, the telescopic support rod 16 adopts a five-stage telescopic type, where the inner rod 161 and the outer rod 162 are relatively inner and outer. Near the end of the operating platform 13, the length of the fourth and fifth telescopic parts is about 10 cm, so that the operator can flexibly adjust the support length of the telescopic support rod 16 according to different work requirements. In actual use, the operator stretches the telescopic support rod 16 to the required length, one end is fixed to the base 11 or the extension plate 12 by bolts, and the other end is selected from the clamping groove 141 on the bottom surface of the expansion plate 14 for clamping. To achieve a good support effect. In this way, the telescopic support rod 16 can not only maintain the required height or angle, but also ensure the stability of the expansion plate 14 during use, thereby improving the practicality and safety of the entire maintenance platform. Further, any expansion plate 14 is supported by at least two front and rear telescopic support rods 16. This telescopic support rod 16 not only enhances the structural integrity and adaptability of the maintenance platform, but also ensures stable use in complex or changing working environments. The length of the support rod can be quickly adjusted through simple operations, realizing fast and convenient adjustment, which not only improves the practicality of the telescopic support rod 16, but also ensures efficiency and safety during the operation process.

[0042] In order to further increase the stability of the maintenance platform, two extension plates 12 are horizontally arranged on both sides of the base 11, and the extension plates 12 and the expansion plates 14 are arranged longitudinally correspondingly, the ends of the extension plates 12 are hinged to the base 11, and the bottom surface of the extension plates 12 is arranged in contact with the ground. The extension plates 12 provide a larger support area. The longitudinal corresponding arrangement of the extension plates 12 and the expansion plates 14 further ensures the balance and stability of the entire maintenance platform when in use.

[0043] A G-type stopper 181 is also provided to limit and fix the extension plate 12 when the extension plate 12 is stored. One end of the G-type stopper 181 is fixed to the hydraulic support 151, and the other end is connected to the extension plate 12. The extension plate 12 is limited by the stopper bolt 1811 on the G-type stopper 181. At this time, the extension plate 12 is arranged vertically with the base 11. When the extension plate 12 is folded up, in order to ensure that it is stably and safely maintained in a vertical state, the stopper bolt 1811 on the G-type stopper 181 is designed to be parallel to the extension plate 12 and extend inward along the extension plate 12. In this way, when the extension plate 12 tends to fall downward due to its weight, the extended stopper bolt 1811 can effectively block it and prevent the extension plate 12 from accidentally falling or loosening. Through this mechanism, not only the stable storage of the extension plate 12 when not in use is guaranteed, but also the safety and reliability during operation are ensured. This not only optimizes space utilization, but also reduces the complexity during storage and transportation. By simply turning the limit bolt 1811, the operator can easily achieve stable setting and release of the extension plate 12, which improves efficiency while ensuring safety during operation.

[0044] Furthermore, a grooved handle is provided on the extension board 12. The grooved handle is not only convenient for the operator to grasp when moving or adjusting the extension board 12, but also because of its recessed design, the handle will not protrude or obstruct the surrounding space when not in use, ensuring the overall smoothness and safety of the platform. Whether adjusting the position and angle of the extension board 12 or carrying the platform, the grooved handle provides a stable and comfortable grip point. At the same time, due to its recessed design, the handle is less affected by external impact, thereby extending the service life and reducing maintenance requirements.

[0045] In general, the maintenance platform takes into account the needs under different working conditions. The combination of the adjustable lifting component 15, the expansion board 14 and the extension board 12 provides a flexible and stable working environment. At the same time, the foldable expansion board 14 enhances the portability and storage efficiency of the platform. The expansion board 14 slides easily when not in use, so that it overlaps with the operating platform 13 and can be quickly stored by separating the components. This not only saves storage space, but also facilitates the movement of the platform between different work locations. Similarly, the foldability of the extension board 12 further improves the flexibility of the platform. The extension board 12 can be easily folded along its hinge point, so that the maintenance platform takes up less space during storage and transportation, making it easier to carry. Whether it is moving within the photovoltaic power station or carrying between multiple sites, these settings reduce the difficulty of logistics and improve the flexibility of operation. The maintenance platform is not only fully functional when in use, but also efficient and convenient when carrying and storing.

[0046] On the basis of the above embodiment, the maintenance platform is also provided with a guardrail 19 to enhance safety and flexibility. At least two plug-in blocks 191 are provided at the bottom of the guardrail 19, and a plurality of plug-in slots 131 are provided on the upper surface of the operating platform 13 and the upper surface of the expansion board 14, and the plug-in blocks 191 are arranged one-to-one with the plug-in slots 131. In this way, the guardrail 19 can be installed or removed quickly and safely, providing flexible configuration options for the operating platform 13. The one-to-one correspondence between the plug-in blocks 191 and the plug-in slots 131 ensures that the guardrail 19 can be firmly fixed in the required position while providing sufficient strength to withstand the pressure and impact that may be encountered in daily use. This quick connection mechanism not only simplifies the installation process, but also allows the guardrail 19 to be reconfigured according to specific working environments or task requirements. In addition, since the guardrail 19 can be easily disassembled, this further increases the adaptability of the maintenance platform, allowing it to be flexibly used in environments where space is limited or a larger range of activities is required. While ensuring the safety of operators, the maintenance platform also improves its applicability and work efficiency.

[0047] Furthermore, since the two expansion boards 14 are on both sides of the operating platform 13, multiple guardrails 19 are plugged into the expansion board 14, that is, the three outer sides of the expansion board 14 are plugged with guardrails 19 to provide comprehensive safety protection. The safety requirements on both sides of the operating platform 13 are fully considered to ensure that the operators are always in a safe environment when the expansion space is used. The two adjacent guardrails 19 on the expansion board 14 are connected by rotation. When the expansion board 14 is not in use or the platform needs to be transported, the guardrail 19 can be easily disassembled. The guardrails 19 on both sides of the expansion board 14 realize the folding function through the rotation connection, so that they can be superimposed on each other to form a compact unit. This reduces the space occupied by the guardrail 19 during storage and transportation, and also avoids the confusion and complexity during the disassembly and storage process. Through this folding and storage mechanism, the guardrail 19 of the maintenance platform not only provides the necessary safety guarantee, but also provides convenience and practicality. The storage solution can significantly reduce the burden on the staff and improve the convenience of operation.

[0048] At the same time, a storage groove 111 for placing the guardrail 19 is provided on the upper surface of the base 11. The storage groove 111 matches the shape of the guardrail 19 to ensure that the guardrail 19 can be placed therein to prevent sliding or damage during movement or storage. Not only does it save additional storage space, but it also makes the management and use of the guardrail 19 more efficient. The operator can quickly take out or put back the guardrail 19 from the groove, simplifying the platform construction and disassembly process. In addition, when the maintenance platform needs to be moved to another work site, this embedded storage design significantly reduces the required transportation space, making the overall handling and configuration easier. Another key advantage is that the storage groove 111 can protect the guardrail 19. When the guardrail 19 is not in use, the storage groove 111 provides it with a safe and protective storage location to prevent damage that may be caused by accidental collisions or severe weather conditions.

[0049] Here, the use process of the maintenance platform is further explained. When using the maintenance platform, first determine whether to unfold the extension plate 12 according to the specific terrain and working space requirements. If the working area is large or the ground soil is soft, it is necessary to unfold the extension plate 12 because it can provide a wider support area and improve the stability of the platform. The specific operation of unfolding the extension plate 12 is achieved by rotating the limit bolt 1811 on the G-type limiter 181, so that the extension plate 12 can be smoothly unfolded along the hinge of the base 11. Subsequently, the guardrail 19 is installed. The guardrail 19 is equipped with a quick plug-in block 191 and a plug-in slot 131, and the operator quickly installs the guardrail 19 on the edge of the operating platform 13 and the expansion plate 14. Then, the operator uses the four hydraulic struts 151 located on the base 11 to adjust the height of the operating platform 13. Each hydraulic strut 151 can be operated independently, allowing the height of each corner of the platform to be adjusted to meet the maintenance needs of photovoltaic panels at different heights. In order to further expand the working area, the operator unfolds the expansion plate 14 along both sides of the operating platform 13. The expansion board 14 is slidably connected to the top surface of the operating platform 13 through the separation components (slide 172 and slider 171) on its bottom surface, so that the expansion board 14 can slide smoothly along the operating platform 13 and be quickly unfolded when needed. Once the expansion board 14 is fully unfolded, the operator adjusts the length of the telescopic support rod 16 to adapt to different working conditions and ensure that the expansion board 14 is firmly supported. After the work is completed, the expansion board 14 and the extension board 12 are put away, and the G-type limiter 181 is used to ensure that the extension board 12 is stored vertically and firmly when not in use. The entire maintenance platform is in a compact state at this time, which is convenient for transportation or storage. Through this series of operations, the maintenance platform provides an efficient, safe and flexible working environment, which is suitable for various high-altitude work scenarios.
