Description

Technical Field

[0001] The invention relates to a single support structure for repairing and replacing a damaged bracket of a photovoltaic load-bearing cable and a use method thereof, belonging to the technical field of solar power generation. Background Art

[0002] With the continuous development of the photovoltaic industry, flexible photovoltaic support systems have been widely used in the fields of fish pond photovoltaics, agricultural photovoltaic complementarity, tea photovoltaic complementarity, etc. The flexible photovoltaic support system mainly includes photovoltaic load-bearing cables for supporting photovoltaic brackets and photovoltaic modules, and multiple support frames for supporting photovoltaic load-bearing cables. The support frames include columns and brackets arranged on the columns.

[0003] During the operation of photovoltaic power generation, the brackets on the columns may be partially or completely damaged under the influence of factors such as strong typhoons or earthquakes, which will affect the bearing capacity and stability of the flexible photovoltaic support system and pose a threat to the safe operation of photovoltaic brackets and photovoltaic modules. Therefore, when the brackets are damaged, they need to be repaired and replaced in time.

[0004] The Chinese patent document with the publication number CN116175464A discloses a device and method for the maintenance and replacement of a support for a water surface photovoltaic system, including a top support unit, which is fixed above the main support column, including a bottom plate, a telescopic cylinder, and an inclined pad. The upper surface of the inclined pad is in close contact with the lower surface of the photovoltaic support rod. By controlling the extension of the telescopic cylinder, the inclined pad is lifted upward to temporarily support and position the photovoltaic support rod; the diagonal support unit is fixedly arranged on the side wall of the main support column and located below the detachable support component, including a diagonal support rod and a positioning component. The two extended sides of the photovoltaic support rod are positioned relative to the main support column by the diagonal support rod, so as to provide auxiliary temporary support for the photovoltaic support system during the disassembly process. By presetting temporary supports in the middle and on both sides of the photovoltaic support rod, the technical effect of overhauling and replacing the support of a single photovoltaic substring is achieved without removing the components and main beams on the photovoltaic support, thereby ensuring the normal operation of the photovoltaic system.

[0005] However, the device relies on the photovoltaic support rod to temporarily support the photovoltaic components on it, which has great limitations. When the photovoltaic support rod is damaged, the device cannot be used to replace the photovoltaic support rod. In addition, the upper end of the diagonal support rod in the device is fixedly connected to the photovoltaic support rod by a bolt group, and it is necessary to drill holes on the photovoltaic support rod at the position corresponding to the bolt group, which reduces the convenience of operation and use of the device, thereby reducing the efficiency of bracket maintenance and replacement. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a single support structure for repairing and replacing a damaged bracket of a photovoltaic load-bearing cable and a method of using the same.

[0007] The present invention is achieved through the following technical solutions:

[0017] A method for using a single support structure for repairing and replacing a damaged photovoltaic load-bearing cable bracket comprises the following steps:

[0018] Step 1: Adjust the position of the single support structure as required, and then clamp A and clamp B tightly and fix them on the damaged column of the support frame to install and fix the single support structure;

[0019] Step 2: Push the load-bearing cable support mechanism upward through the jacking mechanism, and make the photovoltaic load-bearing cable correspondingly snap into the load-bearing cable limit assembly at the end of the top support rod;

[0020] Step 3: Continue to push the load-bearing cable support mechanism upward through the jacking mechanism to support the photovoltaic load-bearing cable and unload the damaged bracket;

[0025] 2. When the single-support bracket unloading device is installed and fixed to the column, there is no need to drill holes on the support frame, so as to avoid stress concentration or damage to the support frame. At the same time, the operation convenience of the single-support bracket unloading device is improved, thereby improving the maintenance and replacement efficiency of the damaged bracket.

[0026] 3. The support frame can be quickly and non-destructively installed and fixed to the column through clamps A and B, which facilitates timely repair and replacement of damaged brackets to ensure the support frame's bearing capacity and supporting stability for the flexible photovoltaic support system, thereby ensuring the safe operation of the photovoltaic bracket and photovoltaic modules.

[0027] 4. The photovoltaic load-bearing cable is limited by the cooperation of the two limit blocks in the load-bearing cable limit assembly, so that the photovoltaic load-bearing cable has only upward freedom, preventing the photovoltaic load-bearing cable from slipping off the top support rod during the lifting process of the jack, effectively ensuring the safety and operability of the single support structure when the jack is lifted upward.

[0028] 5. Use multiple vertical limit blocks to limit the base in the horizontal direction to prevent the jack from moving sideways, and use horizontal limit blocks to support the middle part of the jack to prevent the jack from tipping over, which is conducive to the safe removal and replacement of damaged brackets.

[0029] 6. The structural structure is relatively simple. The single-support bracket unloading device can be made using waste materials at the construction site, which effectively improves the comprehensive utilization rate of materials at the construction site and reduces the production cost of the single-support bracket unloading device.
