Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic support systems, and more specifically, relates to a device and method for repairing and replacing supports of a water surface photovoltaic system. Background Art

[0002] With the increasing scarcity of traditional energy and the deteriorating environment, the fossil fuel-dependent energy structure has already caused significant negative environmental, economic, and social impacts. "Promoting a revolution in energy production and consumption and building a clean, low-carbon, safe, and efficient energy system" is the inevitable choice for energy security and sustainable development. Solar energy is an important renewable energy source that is inexhaustible, safe, economical, and pollution-free. The development and utilization of solar energy resources is a key measure in my country's energy development strategy and in adjusting its power structure. However, during the construction of offshore photovoltaic systems, hidden defects can easily occur in the mounting brackets during the delivery, stacking, transportation, and installation stages. After the project is installed and put into operation for a period of time, some damaged components may deform, affecting the solar panel's sun-facing angle and flatness, reducing solar energy utilization, and increasing the safety risk of overall instability in the mounting system.

[0003] To address this issue, during offshore photovoltaic construction, when a PV mount becomes damaged or deformed and requires replacement, the following procedures must be followed: First, the power supply to the PV array or substring must be disconnected. Then, to prevent damage to the components due to overall mount instability and settlement, all substring components in the area to be replaced must be removed. Next, the associated main beams and purlins must be removed to ensure the mount system is free of stress. Finally, damaged mount components are replaced one by one. Once the mount is repaired, the associated main beams, purlins, and components are restored, allowing the PV array and array to resume power generation.

[0004] For the general on-site photovoltaic bracket replacement construction method, the photovoltaic bracket can be replaced, but there are the following problems: (1) During the dismantling of the photovoltaic components, direct dismantling without other temporary auxiliary supports will easily cause secondary damage to the components; (2) If all components are dismantled during the maintenance and replacement process, it will lead to a large dismantling process, and the materials need to be transported to the shore for temporary stacking, resulting in high construction costs and a long construction period; (3) Using the above method requires cutting off the power supply of the array or sub-string, which will affect the power generation and operation of the project and increase the maintenance cost. Summary of the Invention

[0005] In response to the above defects or improvement needs of the prior art, the present invention provides a device for inspecting and replacing supports of a water surface photovoltaic system. By presetting temporary supports in the middle and on both sides of the photovoltaic support pole, the technical effect of inspecting and replacing the supports of a single photovoltaic sub-string is achieved without removing the components and main beams on the photovoltaic support. In addition, the pile top inclined beam protection device adopts a pad with the same angle as the inclined beam and three jacks at the front, middle and rear for adjustment, which not only ensures the stability of the upper part, but also is suitable for the construction of supports at different heights.

[0033] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0034] 1. The present invention relates to a device for repairing and replacing supports for a water-based photovoltaic system. By pre-setting temporary supports in the middle and on both sides of the photovoltaic support pole, the device enables the repair and replacement of supports for individual photovoltaic substrings without removing the components and main beams on the photovoltaic support. Furthermore, the pile-top inclined beam protection device utilizes pads at the same angle as the inclined beam and three jacks at the front, middle, and rear for adjustment, ensuring the stability of the upper portion and adapting to support construction operations at different heights. The device has a simple structure and is easy and flexible to install and remove. The two devices, pile-top and pile-side, ensure the safety of the substring components and the integrity of the structure during replacement. Furthermore, the installation process does not affect the upper components and electrical cables, allowing construction to be carried out under normal photovoltaic system operation conditions, thereby ensuring the project's power generation revenue.

[0035] 2. The present invention provides a device for repairing and replacing supports for a water surface photovoltaic system. By adopting a cylinder as a linear motion drive component and combining it with a connecting rod, the lifting and downward control of the diagonal support rod is realized. The design of a self-adjusting lifting method greatly eliminates the tedious process of installing multiple rods that requires the cooperation of multiple people. Only one person needs to fix the diagonal support unit to the outside of the main support column through the clamp fixing part to complete the installation process of the diagonal support unit. The pre-installation process is then completed by controlling the extension length of the driving cylinder so that the extended end of the second diagonal support rod contacts the photovoltaic support rod. The bolt group is then used for positioning to complete the entire installation of the diagonal support unit, which is easy to operate and improves work efficiency.

[0036] 3. The present invention provides a device for repairing and replacing supports for a water-based photovoltaic system. By providing a buffer structure and a pressure sensor at the lower end of a connecting slider, the control system effectively controls the lifting of the diagonal support rods. The control system uses pressure parameters to sense whether the diagonal support rods are in contact with the upper photovoltaic support rods, thereby controlling the start and stop states of the cylinders and preventing secondary damage to the photovoltaic supports caused by overshoot.

[0037] 4. The present invention provides a device for inspecting and replacing a support for a water surface photovoltaic system. By adding an alignment detection unit to the front end of the second diagonal support rod, when the photovoltaic support rod comes into contact with the abutment portion, the pressure is transmitted to the first pressure sensor by the spring, thereby comparing the pressure difference sensed on both sides to determine whether the photovoltaic support rod is in a position facing the front end of the second diagonal support rod, and then guiding the drive motor to adjust the position.

[0053] By installing the top support unit (7) and the diagonal support unit (6), the photovoltaic support is completely positioned for a second time as a whole, thereby achieving a replacement operation for the original photovoltaic support.

[0054] When in use, the staff first identifies the photovoltaic bracket that needs to be replaced and installs the top support unit to the corresponding position; then, the lower end of the diagonal support rod is fixed to the main support column through the positioning assembly, and the upper end of the diagonal support rod is fixed near the two ends of the photovoltaic support pole through the bolt group, thereby positioning the angle of the photovoltaic support pole; then, the telescopic cylinder in the top support unit is controlled to extend, so as to ensure that the top support unit is in close contact with and bears the load on the photovoltaic support pole; then, the detachable support assembly 4 is manually removed. At this time, the top support unit is mainly responsible for bearing the upper load, and the diagonal support unit is responsible for maintaining the inclination angle of the fixed photovoltaic support pole; then, after replacing the new photovoltaic support assembly, the top support unit and the diagonal support unit are removed to complete the replacement construction of the photovoltaic bracket.

[0055] In an embodiment of the present invention, by pre-setting temporary supports in the middle and on both sides of the photovoltaic support pole, the technical effect of inspecting and replacing the bracket of a single photovoltaic sub-string is achieved without removing the components and main beams on the photovoltaic bracket; in addition, the pile top inclined beam protection device adopts a pad with the same angle as the inclined beam and three jacks at the front, middle and rear for adjustment, which not only ensures the stability of the upper part, but also is suitable for bracket construction operations at different heights; the structure is simple, and the installation and disassembly are convenient and flexible. Through the two devices on the pile top and pile side, the safety of the components of the sub-string and the integrity of the structure are guaranteed during the replacement process; at the same time, the upper components and electrical cables are not affected during the construction process, and the construction can be carried out under the conditions of normal operation of the photovoltaic system, ensuring the income from the project's power generation.

The protruding end of the second diagonal support rod 620 is provided with a screw hole 632 fixedly connected to the photovoltaic support pole 2.

[0064] In the embodiment of the present invention, the lifting and downward control of the diagonal brace rod are realized by adopting a cylinder as a linear motion driving member and combining it with a connecting rod. The design of the self-adjusting lifting method greatly saves the tedious process of installing multiple rods that requires the cooperation of multiple people. Only one person needs to fix the diagonal brace unit to the outside of the main support column 4 through the clamp fixing part 611 to complete the installation process of the diagonal brace unit. Then, by controlling the extension length of the driving cylinder, the extended end of the second diagonal brace rod 620 contacts the photovoltaic support pole 2, and then positioning is completed by the bolt group.
