[0002] High-pile beam-type photovoltaic (PV) supports are commonly used in composite PV projects such as fishery-solar hybrid and agricultural-solar hybrid projects, where the supports are positioned high above the ground. A single main beam of a high-pile beam-type PV support spans multiple piles, but the distance between adjacent piles is considerable, posing a challenge to the lifting and installation of the main beam and accessories.

[0003] In related technologies, the traditional installation of high-pile beam photovoltaic supports involves erecting temporary scaffolding at the pile foundation and manually installing each photovoltaic support beam one by one in the air, followed by beam segment connection and fixation. This installation method is labor-intensive, difficult to construct, inefficient, and poses significant safety hazards due to working at heights and near edges. Furthermore, the reverse force during the replacement of beam support materials causes swaying for the operators, making them unstable and increasing the risk of falls. In addition, the installation quality cannot be fully controlled.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer and more understandable, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0020] High-pile beam-type photovoltaic (PV) supports are commonly used in composite PV projects such as fishery-solar hybrid and agricultural-solar hybrid projects, where the supports are positioned high above the ground. A single main beam of a high-pile beam-type PV support spans multiple piles, but the distance between adjacent piles is considerable, posing a challenge to the lifting and installation of the main beam and accessories.

[0021] In related technologies, the traditional installation of high-pile beam photovoltaic supports involves erecting temporary scaffolding at the pile foundation and manually installing each photovoltaic support beam one by one in the air, followed by beam segment connection and fixation. This installation method is labor-intensive, difficult to construct, inefficient, and poses significant safety hazards due to working at heights and near edges. Furthermore, the reverse force during the replacement of beam support materials causes swaying for the operators, making them unstable and increasing the risk of falls. In addition, the installation quality cannot be fully controlled.

[0022] Chinese patent publication number CN112575807A discloses a high-pile photovoltaic support system, including a connecting component, a supporting component, a solar panel frame, a suspension component, and an operating platform. The operating platform is a scaffold erected between two piles via the suspension component. Its structure is complex and does not solve the safety hazards of manual installation at high altitudes mentioned above.

[0023] To achieve the above objectives, this utility model provides an installation auxiliary device 100 for a high-pile foundation beam-type photovoltaic support (hereinafter referred to as the installation auxiliary device 100), such as... Figure 1 and Figure 2As shown, the installation auxiliary device 100 includes at least one set of suspension mechanisms 10. Two adjacent suspension mechanisms 10 are mounted on two adjacent or spaced columns 901 of the photovoltaic support. Each suspension mechanism 10 includes a fixing component 20, a support component 30, and a lifting component 40. The fixing component 20 is connected to the column 901. The support component 30 is located at one end of the fixing component 20 and above the column 901. The lifting component 40 is connected to the support component 30. The lifting component 40 includes a pulley block 41 and a lifting member 42 located at one end of the pulley block 41 for fixing the main beam 903.

[0024] The high-pile foundation 902 beam photovoltaic bracket installation auxiliary device 100 of this utility model includes at least one set of suspension mechanisms 10. Two adjacent suspension mechanisms 10 are set on two adjacent or spaced columns 901 of the photovoltaic bracket. Each suspension mechanism 10 includes a fixing component 20, a support component 30, and a lifting component 40. The fixing component 20 is connected to the column 901. The support component 30 is set at one end of the fixing component 20 and located above the column 901. The lifting component 40 is connected to the support component 30. The lifting component 40 includes a pulley block 41 and a lifting member 42 set at one end of the pulley block 41 for fixing the main beam 903. This installation auxiliary device 100 does not require scaffolding. The main beam 903 is lifted to the top of the column 901 through the pulley block 41 to quickly assist in lifting the main beam 903 and connecting it to the column 901 of the photovoltaic bracket. The structure is lightweight, the construction is convenient and not limited by terrain, improves the installation efficiency of the bracket, reduces construction safety risks and ensures construction safety.

[0025] It is understandable that when a main beam 903 is connected to two or more pile foundations 902, two or more suspension mechanisms 10 can be set up, for example as follows: Figure 1 As shown, four pile foundations 902 share a main beam 903, so three sets of suspension structures are set up. Among them, a suspension mechanism 10 is set at the beginning and end of each of the four adjacent pile foundations 902, and a suspension mechanism 10 is set at one of the two in the middle. This can ensure that the two ends of the main beam 903 are lifted at the same time, and also ensure that the middle of the main beam 903 is lifted synchronously, so as to avoid excessive stress difference in various parts of the main beam 903, which would cause deformation and damage to the main beam 903.

[0026] Optionally, the fixing assembly 20 includes a fixing pole 21, a connector 22, and a fixing member 23. The connector 22 and the fixing member 23 are respectively located in the middle and bottom of the fixing pole 21 for connecting to the top and middle of the column 901.

[0027] In this embodiment, the middle and bottom of the fixed pole 21 are connected to the column 901 of the photovoltaic bracket through the connector 22 and the fixing member 23. The column 901 is set on the pile foundation 902 of the photovoltaic bracket. The support component 30 is set at the top of the fixed pole 21 away from the column 901 and is used to support the lifting component 40. The lifting component 40 lifts the main beam 903 from the ground to the top of the column 901 through the pulley block 41. Then it is assembled with the mounting seat at the top of the column 901 to carry out the gradual installation of the photovoltaic bracket.

[0028] Optionally, the connector 22 is arranged perpendicular to the fixed pole 21, so that the fixed pole 21 is arranged at an angle to the column 901, and the fixed pole 21 is tilted away from the force-applying side of the pulley block 41.

[0029] In this embodiment, the connector 22 is used to connect the fixed pole 21 to the top of the column 901. After the fixed pole 21 is installed, it is located on one side of the column 901 and is set at a certain angle to the column 901. The column 901, the fixed pole 21 and the connector 22 form a triangular support structure. The fixed column 901 is the longer inclined side of the triangular support and is tilted away from the force-applying side of the pulley block 41. When the pulley block 41 applies force to lift the main beam 903, the connector 22 not only has the function of stabilizing the assembly of the fixed pole 21, but also resists the force applied by the pulley block 41 through the triangular support structure formed by the connection. This makes the assembly structure of the fixed pole 21 and the column 901 stable during the lifting of the main beam 903, and improves the stability of the lifting process of the main beam 903.

[0030] Optionally, the fastener 23 is configured as a lug, and the column 901 is provided with a first reserved hole, and the lug is connected to the anchor bolt of the first reserved hole.

[0031] Optionally, the column 901 is provided with a second reserved hole, and the connector 22 is a sheet metal part with one end welded to the fixed column 21 and the other end bolted to the second reserved hole.

[0032] Specifically, the support component 30 includes a top flat brace 31 and a hook 32. One end of the top flat brace 31 is connected to the fixing component 20, and the other end is suspended above the column 901. The hook 32 is located on the top flat brace 31 and between the top flat brace 31 and the column 901. One end of the pulley block 41 is detachably connected to the hook 32, and the lifting component 42 is connected to the other end of the pulley block 41.

[0033] In this embodiment, the top flat support 31 and the fixing component 20 are arranged in an F-shaped structure. Specifically, one end of the top support is connected to the end of the fixing rod 21 away from the column 901, so that the other end is suspended above the column 901. The hook 32 is located on the side of the top support facing the top of the column 901. The pulley group 41 is detachably connected to the support component 30 through the hook 32, so that the pulley group 41 can be replaced. After the pulley group 41 and the top support of the support are installed, the main beam 903 is fixed before lifting. Then the main beam 903 is dynamically lifted to the top of the column 901 for assembly.

[0034] Furthermore, in order to improve the stability of the support assembly 30 during the lifting action, a reinforcing rod is provided at the connection between the top support and the fixed pole 21. The reinforcing rod is located inside the angle between the top support and the fixed pole 21. The two ends of the reinforcing rod are respectively connected to the top support and the fixed pole 21, and the three together form a triangular support angle, which improves the structural stability of the top support and the fixed pole 21 and can be used for lifting actions with greater weight.

[0035] Optionally, the pulley block 41 includes a fixed pulley 411, a movable pulley 412, and a tension member 413 wound around both. The fixed pulley 411 is fixedly mounted on the support assembly 30, the movable pulley 412 is connected to the lifting member 42, and the tension member 413 is fixedly connected to the fixed pulley 411 and then movably wound around the movable pulley 412, with the other end facing the ground to apply external force.

[0036] In this embodiment, the relative height and position of the fixed pulley 411 are fixed, the movable pulley 412 is slidably connected to the tension member 413, and the lifting member 42 is located at the bottom of the fixed pulley 411 to fix the main beam 903 before it is lifted as the fixed pulley 411 descends. Then, by applying force to the tension member 413, the movable pulley 412 is lifted, which in turn drives the main beam 903 to be lifted. The lifting assembly 40 fully utilizes the working principle of the pulley block 41, and has a simple structure, small size, light weight, is easy to install and maintain, has strong adaptability and high transmission efficiency, stable and reliable power transmission, and is easy to operate. Using this installation auxiliary device 100 can greatly save manpower, reduce the difficulty of high-altitude operations, and make operation quick.

[0037] Understandably, the tension member 413 is set at an angle to the fixed column 901 when applying force. This angle is not fixed. When multiple suspension mechanisms 10 are set, efforts should be made to ensure that the angles between the tension members 413 of multiple suspension mechanisms 10 and the corresponding fixed columns 901 are the same, ensuring the relative balance of the force applied by the suspension mechanisms 10 during the ascent of the main beam 903. The force applied by the tension member 413 can be applied manually or by using an electric winch. When multiple suspension mechanisms 10 are set, they pull and lift synchronously to ensure the stability of the main beam 903 during the lifting process.

[0038] Optionally, the tension member 413 can be a nylon rope or a metal wire rope.

[0039] The assembly steps of the aforementioned installation auxiliary device 100 mainly include connecting the connecting piece to the second reserved hole on the column 901 by fixing the fixed pole 21 with anchor bolts, and fixing the fixed pole 21 to the column 901. The top flat brace 31 is connected to the fixed pole 21 by welding, and the hook 32 is welded to the lower side of the top flat brace 31. The fixed pulley 411 is fixed to the hook 32. The fixed pulley 411 and the movable pulley 412 are connected by winding nylon rope. The bottom of the movable pulley 412 is directly fixed to the transverse main beam 903 to be installed, and so on. For example, when facing the installation conditions of four pile foundations 902 and the main beam 903 of the column 901, this installation auxiliary device 100 requires three identical suspension mechanisms 10 to lift together. Three people work together to complete the work. The main beam 903 and purlin to be lifted are lifted to the top of the column 901 for installation through the coordinated operation of the suspension mechanisms 10.

[0040] Furthermore, the installation process of the photovoltaic support on the high pile foundation 902 includes at least the following steps: construction preparation → device installation and fixing → assembly of the support main beam 903 and accessories → pre-lifting of the lifting device → lifting of the support main beam 903 → positioning and fixing of the support main beam 903 → purlin installation → inspection and adjustment → construction completion.

[0041] The construction preparation phase begins with the completion of the photovoltaic support foundation and column 901. Next, all necessary tools and equipment, including the installation auxiliary device 100, mobile scaffolding, cotton cloth, wrenches, and rulers, are in place. The quality of all materials is checked, and the use of substandard products is strictly prohibited. Simultaneously, the main beam 903, bearing seats, connecting boxes, purlins, and accessories of the photovoltaic support are transported to the work site. Finally, detailed instructions are given to the installation personnel according to the design drawings.

[0042] In the installation and fixing process, the fixing component 20 with F-type support of the suspension mechanism 10 is fixedly connected to the already installed photovoltaic support column 901 using a movable pin. During installation, the fixing rod 21 is tilted back 40mm away from the column 901 to facilitate the subsequent positioning of the main beam 903. After inserting the movable pin, remember to insert the pin retainer to prevent the pin from falling off; alternatively, a clamp method can be used to fix the fixing rod 21 to the foundation pile of the photovoltaic support (exemplarily the column 901) using a clamp. Two sets of short-row photovoltaic modules are installed, one set at each end; three sets of long-row photovoltaic strings are installed, one set at each end, and one set is installed on the fourth column 901 from west to east. The fixing method is selected according to the support type and terrain.

[0043] After the F-shaped structure is fixed, the pulley block 41 is suspended on the U-shaped hook 32 at the top support. After the entire set of installation auxiliary devices 100 is fixed, the movable pulley 412 and lifting component 42 of each group are placed on the ground. Three sets of suspension mechanisms 10 are installed for short-row photovoltaic strings, and only one set of auxiliary suspension mechanism 10 is added in the middle of the long-row strings.

[0044] Regarding the assembly of the main beam 903 and accessories, each main beam 903 is placed approximately 0.5m to 1m in front of the pile foundation 902 at the ground level of each group of girders. Each group consists of 3 main beams 903 (4 main beams 903 in a long row). Each main beam 903 is connected using connector 22, with the nuts facing downwards as required by the installation process, and all bolts are tightened. Tightening is done symmetrically on both sides. After installation, an inspection is conducted, and the next step can begin once all bolts are tightened. The lifting points of the main beam 903 are determined based on the location and number of lifting devices. For example, each lifting point uses a nylon rope as a lifting ring, serving as the suspension point for the hook 32 of the movable pulley 412 during lifting. A 500mm wide cotton cloth is wrapped around the points where the main beam 903 may come into contact with the pile foundation 902 and column 901 during lifting as a protective layer to prevent damage to the galvanized layer caused by collisions between the main beam 903 and the pile foundation 902 and column 901 during lifting.

[0045] In the pre-lifting stage of installation assistance, after the lifting component 42 is firmly connected to the main beam 903, the initial lifting is carried out. After the tension component 413 is tightened, the lifting is stopped. Observe whether the lifting device is synchronized and whether the fixed parts of the upright and the suspension mechanism 10 are deformed or displaced. If there are no such phenomena, the next step can be carried out.

[0046] During the lifting of the main beam 903, it is confirmed again that the connecting nut is facing downwards. Exemplarily, during manual force application, one worker slowly pulls the nylon rope on each device, gradually bringing the main beam 903 closer to the pile foundation 902. One worker directs the lifting process to ensure synchronization and prevent serious collisions that could damage the galvanized layer of the main beam 903. After the main beam 903 contacts the pile foundation 902, observe whether the protective layer has shifted. During subsequent lifting, when the main beam 903 rises to the welding position between the pile foundation 902 and the column 901, it must be raised slowly to prevent serious collisions that could damage the galvanized layer. After the main beam 903 slowly contacts the column 901, the nylon rope is pulled simultaneously again to raise the main beam 903 to the top of the column 901, then slowly released, allowing the main beam 903 to descend to the top of the support column 901.

[0047] During the positioning and fixing of the main beam 903 of the photovoltaic bracket, after the main beam 903 is initially positioned, the installers check the positioning and make minor adjustments to the east and west ends of the main beam 903 until it is 1657mm from the top of the first and last columns 901, ensuring that the main beam 903 is completely seated within the bearing of the mounting base at the top of the column 901. After the main beam 903 of the photovoltaic bracket is adjusted to the connection point with the column 901, the main beam 903 of the bracket is fixed in place using the bearing.
