Description

Technical Field

[0001] The invention relates to a double-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 double support structure for repairing and replacing a damaged bracket of a photovoltaic load-bearing cable and a method of using the double support structure.

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

[0008] A double-support structure for repairing and replacing damaged photovoltaic load-bearing cables and brackets, comprising two photovoltaic load-bearing cables arranged side by side and a double-support bracket unloading device, wherein the two photovoltaic load-bearing cables are supported together by a plurality of support frames, wherein the support frames comprise columns and brackets arranged on the columns, and the double-support bracket unloading device is arranged on the columns of the support frames where the brackets have been damaged, and the double-support bracket unloading device supports the two photovoltaic load-bearing cables upward to unload the damaged brackets.

[0009] The double-support bracket unloading device includes a load-bearing frame and two load-bearing cable support mechanisms. The load-bearing frame is arranged on a column, and the two load-bearing cable support mechanisms are arranged side by side on the load-bearing frame and support two photovoltaic load-bearing cables in a one-to-one correspondence.

[0010] The support frame includes a hoop A and a hoop B. Two horizontal support rods are symmetrically provided on the hoop A along its radial direction, and the two horizontal support rods are arranged coaxially. The hoop B is arranged coaxially with the hoop A, and the hoop B is located below the hoop A. The hoop B is connected to the two horizontal support rods through diagonal support rods respectively.

[0011] The load-bearing cable supporting mechanism includes a base, a jacking assembly and a vertical support rod. The base is arranged on the load-bearing frame, the lower end of the jacking assembly is connected to the base, the lower end of the vertical support rod is connected to the upper end of the jacking assembly, and a limiting groove is provided at the upper end.

[0012] The base comprises a square bottom plate and a limiting frame arranged on the square bottom plate.

[0013] The limiting frame comprises a circular ring and a plurality of inclined bars evenly distributed at the bottom of the circular ring.

[0014] The circular rings are connected to the midpoints of the sides of the top surface of the square bottom plate through the inclined bars, and the angle between the inclined bars and the square bottom plate is 45° to 60°.

[0015] The jacking assembly is a hydraulic jack.

[0016] The limiting groove is U-shaped, and the U-shaped opening faces upward. The opening width of the limiting groove is adapted to the diameter of the photovoltaic load-bearing cable, and the depth of the limiting groove is not less than 1.5 times the diameter of the photovoltaic load-bearing cable.

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

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

[0019] Step 2: Operate the lifting assemblies in the two load-bearing cable support mechanisms to push the vertical support rods upward, and make the two photovoltaic load-bearing cables correspondingly snap into the limit grooves on the vertical support rods of the two load-bearing cable support mechanisms;

[0020] Step 3: Simultaneously operate the lifting components in the two load-bearing cable support mechanisms to move the vertical support rods further upward to support the two photovoltaic load-bearing cables and unload the damaged brackets;

[0021] Step 4: Remove the damaged bracket on the column and install and fix the new bracket to the column;

[0022] Step 5. Simultaneously operate the lifting components in the two load-bearing cable support mechanisms to move the vertical support rod down to the bottom of the photovoltaic load-bearing cable, and make the new bracket support the photovoltaic load-bearing cable. Then loosen the clamp A and the clamp B, and separate the double support structure from the column to realize the disassembly of the double support structure for reuse.

[0023] The beneficial effects of the present invention are:

[0024] 1. A double-support bracket unloading device is used to replace the damaged bracket to support the two photovoltaic load-bearing cables and unload the damaged bracket. The damaged top support rod, damaged column and damaged diagonal support rod can be repaired or replaced, that is, all components of the damaged bracket can be repaired and replaced, which improves the practicality of the double-support bracket unloading device.

[0025] 2. When the double-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 double-support bracket unloading device is improved, thereby improving the maintenance and replacement efficiency of damaged brackets.

[0026] 3. The support frame can be quickly and non-destructively installed and fixed to the column 1 through the clamps A and B, so as to facilitate timely repair and replacement of damaged brackets, so as to ensure the bearing capacity and supporting stability of the support frame 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 limit groove, so that the photovoltaic load-bearing cable has only upward freedom, preventing the photovoltaic load-bearing cable from shifting sideways or sliding off the vertical support rod during the lifting process of the hydraulic jack, effectively ensuring the safety and operability of the double support structure when the hydraulic jack is lifted upward.

[0028] 5. The hydraulic jack is limited by the limit frame to prevent it from lateral movement or tipping over, which improves the safety of operation and facilitates the safe removal and replacement of damaged brackets.

[0029] 6. The lifting heights of the lifting assemblies in the two load-bearing cable support mechanisms can be determined separately to meet the support requirements of the double-support bracket unloading device for the two photovoltaic load-bearing cables, the requirements for unloading the damaged brackets, and the inclination requirements of the photovoltaic brackets and photovoltaic modules on the two load-bearing cables during bracket replacement.

[0030] 7. The structural structure is relatively simple. The double-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 double-support bracket unloading device.

[0041] like Figures 1 to 8As shown, the double support structure for repairing and replacing damaged photovoltaic load-bearing cables and brackets described in the present invention includes two photovoltaic load-bearing cables 16 arranged side by side and a double support bracket unloading device. The two photovoltaic load-bearing cables 16 are supported together by a plurality of support frames, and the support frame includes a column 1 and a bracket arranged on the column 1. The double support bracket unloading device is arranged on the column 1 of the support frame where the bracket has been damaged, and the double support bracket unloading device supports the two photovoltaic load-bearing cables 16 upward to unload the damaged bracket. Figure 1 As shown, when in use, the bracket is located above the water surface 21, and the damaged bracket includes a damaged top support rod 19, a damaged column 17 and two damaged diagonal support rods 18.

[0042] The double-support bracket unloading device includes a load-bearing frame and two load-bearing cable support mechanisms. The load-bearing frame is arranged on the column 1, and the two load-bearing cable support mechanisms are arranged side by side on the load-bearing frame and support two photovoltaic load-bearing cables 16 in a one-to-one correspondence.

It is recommended that the horizontal support rod 10 is made of channel steel or box steel and welded to the clamp A14; the size and strength of the clamp A14 and the clamp B15 must meet the force requirements of the single support structure. The diagonal support rod 12 is made of angle steel or channel steel.

The base is arranged on the load-bearing frame, the lower end of the lifting assembly 4 is connected to the base, the lower end of the vertical support rod 2 is connected to the upper end of the lifting assembly 4, and a limiting groove is provided at the upper end. When in use, the vertical support rod 2 is made of box-shaped steel, and its length is determined according to the lifting height and the installation height of the load-bearing frame. The photovoltaic load-bearing cable 16 is limited by the limiting groove, so that the photovoltaic load-bearing cable 16 only has an upward degree of freedom, preventing the photovoltaic load-bearing cable 16 from shifting sideways or sliding off the vertical support rod 2 during the lifting process of the hydraulic jack, and effectively ensuring the safety and operability of the double support structure when the hydraulic jack is lifted upward.

[0051] Step 1: Adjust the position of the double support structure as required, and then clamp A14 and clamp B15 tightly and fix them on the damaged column 1 in the support frame to install and fix the double support structure.

[0052] Step 2: respectively operate the lifting assemblies 4 in the two load-bearing cable support mechanisms to push the vertical support rod 2 upward, and make the two photovoltaic load-bearing cables 16 correspondingly snap into the limiting grooves on the vertical support rods 2 of the two load-bearing cable support mechanisms.

[0053] Step 3: Simultaneously operate the lifting components 4 in the two load-bearing cable support mechanisms to move the vertical support rod 2 upwards, support the two photovoltaic load-bearing cables 16, and unload the damaged bracket. The lifting heights of the lifting components 4 in the two load-bearing cable support mechanisms can be determined separately to meet the support requirements of the double-support bracket unloading device for the two photovoltaic load-bearing cables 16, the requirements for unloading the damaged bracket, and the requirements for the inclination angles of the photovoltaic brackets and photovoltaic modules on the two load-bearing cables 16 during bracket replacement.
