Description

Technical Field

[0001] This utility model relates to the field of bracket inspection and maintenance, and in particular to a photovoltaic flexible bracket inspection and maintenance device. Background Technology

[0002] Flexible photovoltaic (PV) brackets are a new type of support structure used in photovoltaic power generation systems. They are mainly used for the installation of PV modules in different environments such as rooftops and ground surfaces. Compared with traditional rigid brackets, flexible PV brackets have stronger adaptability and flexibility, and can adapt to different shapes and irregular surfaces, such as curved roofs or irregularly shaped buildings. They are made of high-strength, lightweight materials, such as aluminum alloys, stainless steel or composite materials, and have good corrosion resistance and wind resistance.

[0003] This type of support system is characterized by its light weight and easy installation, which can reduce labor costs and installation time. It is particularly suitable for rapid deployment and large-scale photovoltaic projects. The flexible support design allows photovoltaic modules to be arranged at the optimal angle and direction, thereby maximizing energy collection efficiency. In addition, the application of flexible photovoltaic supports also helps to reduce the burden on buildings, avoid damage to the structure, and improve the stability and durability of photovoltaic power generation systems.

[0004] The inspection and maintenance of photovoltaic flexible support systems mainly includes regularly checking the structural integrity of the support system, the tightness of the connecting parts, and the integrity of the anti-corrosion coating to ensure that the support system is free from deformation, loosening, or rust. Timely repair or replacement is necessary to extend the service life of the support system. During inspection and maintenance, workers need to carry toolboxes and use different tools for different situations. However, due to the height of the support system, scaffolding is required to lift workers up during maintenance. During the maintenance process, tools may slip from their hands and fall to the ground. In this case, workers have to climb down from the scaffolding to retrieve the fallen tools, which is time-consuming and laborious. Therefore, a photovoltaic flexible support system inspection and maintenance device is proposed to solve the above problems. Utility Model Content

At this time, workers can only climb down from the scaffolding to retrieve the fallen tools, which is time-consuming and laborious.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic flexible support inspection and maintenance device, including a toolbox, an anti-fall-off component installed on the outside of the toolbox, and a fixing component installed inside the toolbox;

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by moving the lever, the fixing block is compressed and the spring is opened, and the rotating shaft is rotated in conjunction with the spring, so that the rope is wound into the outer shell, thus securing the tool. The tool is prevented from falling directly to the ground by the pull of the rope, and the tool can be pulled up by the rope, saving time and effort.

[0024] 2. In this utility model, by squeezing the handle under the limit of the two slide rails, the pull rope pulls the slide plate to compress the second spring, allowing the insertion rod to disengage from the toolbox, thus keeping the partition stable and preventing shaking, while also making it convenient to retrieve the tools on the lower layer.

[0035] Reference Figure 1 , Figure 4 , Figure 5The fixing assembly includes a partition 10, which is slidably connected to the inner wall of the toolbox 1. Two inner shells 11 are fixedly connected to the inner side of the partition 10. A pull rope 12 is slidably connected inside the inner shell 11. A slide plate 13 is fixedly connected to the outside of the pull rope 12. A plug rod 14 is fixedly connected to the outside of the slide plate 13.

[0036] Working Principle: When using this device to inspect and maintain photovoltaic flexible supports, workers climb scaffolding to the vicinity of the supports and check for looseness or damage. When a part needs to be tightened or replaced, the toolbox 1 is opened, the tool is taken out from the partition 10, and the fixing ring 6 is pulled while the lever 9 is turned. This causes the fixing block 8 to compress the spring 7 and open the notch of the fixing ring 6. At this time, the fixing ring 6 hooks onto the through hole of the tool, and the lever 9 is released. The spring 7 will immediately push the fixing block 8 back to its original position, filling the notch of the fixing ring 6 and preventing the fixing ring 6 from falling off the tool. When the tool is used again, the rotating shaft 3 is driven by the rope 5 to rotate, which charges the spring 4. If the tool is accidentally slipped out of the hand, the rope 5 will prevent it from slipping out of the hand. The tool can be retrieved directly along rope 5. When it is necessary to rewind rope 5, release the retaining ring 6. The spring 4 will immediately drive the shaft 3 to rotate and begin rewinding rope 5, causing rope 5 to retract automatically. When it is necessary to use the tool at the bottom of toolbox 1, under the limit of slide rail 16, squeeze handle 17 to drive the pull ropes 12 on both sides to press the slide plate 13 and compress spring 15, causing the insertion rod 14 to disengage from toolbox 1. Then, the partition 10 can be taken out. After putting the partition 10 back, release handle 17. Spring 15 will immediately push slide plate 13, causing insertion rod 14 to pop out and reset, inserting into toolbox 1, fixing partition 10 and preventing shaking that could cause tool displacement. The operation is convenient and labor-saving.
