Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a foldable photovoltaic power generation module. Background Technology

[0002] Photovoltaic power generation technology directly converts solar energy into electrical energy through the photovoltaic effect. Its core lies in using photovoltaic panels made of semiconductor materials to absorb photons and excite electron transitions to form an electric current. While this clean energy technology has broad prospects, its actual deployment, especially the transportation and installation of power generation components, faces challenges.

[0003] Because photovoltaic panels are thin sheets of glass, their thinness and fragile edges make them extremely susceptible to damage during transportation. Existing technologies use custom-made wooden crates and cushioning pads for protection, which can reduce the probability of damage during transportation and storage. However, the multi-layered stacked modules also bear enormous pressure, causing micro-cracks in the photovoltaic panels that are difficult to see with the naked eye. These hidden damages only gradually become apparent after electricity is applied, leading to a permanent decrease in power generation efficiency. Furthermore, conventional support structures used with photovoltaic panels are easily deformed and rendered unusable during transportation, such as when turning on narrow roads or being hoisted on construction sites, due to bending or collisions, thus increasing time and logistics costs.

[0004] Even if the photovoltaic panels and their supporting brackets arrive at the site smoothly, damage to the panels is highly likely due to a lack of professional skills among the construction workers, who may use improper stacking methods, such as laying them flat. Furthermore, during installation, current technology involves installing the photovoltaic panels after installing the brackets. Construction workers often need to move the panels to the installation surface, a process that is highly susceptible to scratches or damage due to improper handling, affecting subsequent operation of the panels. Utility Model Content

[0005] The purpose of this invention is to provide a foldable photovoltaic power generation module to solve the above-mentioned problems.

[0006] This utility model is achieved through the following technical solution: A foldable photovoltaic power generation module includes a keel, on which an adjustment component is provided. The adjustment component includes several longitudinal beams, and several transverse beams are fixedly connected to the side walls of each longitudinal beam. The side walls of the transverse beams and the top wall of the keel are provided with slots, and photovoltaic panels are detachably connected to the transverse beams and the keel through the slots. Sliding grooves are provided on the side walls of the keel and the longitudinal beams near the adjacent longitudinal beams, and the longitudinal beams slide against the adjacent side walls through the sliding grooves. Fixed columns are hinged to the bottom of each longitudinal beam, and clamps are provided at the bottom of each fixed column.

[0007] Compared with the prior art, this utility model has the following advantages and beneficial effects: This solution utilizes the design of longitudinal beams and chutes. By pulling the longitudinal beams, the distance between different crossbeams can be changed, thereby adjusting the distance between different photovoltaic panels. Compared to existing technologies, this solution allows for the folding of photovoltaic power generation modules by adjusting the structure supporting the photovoltaic panels. This enables the basic assembly of photovoltaic panels to be completed in the factory, simplifying the installation process on the construction site and reducing the professional skills required for photovoltaic panel installation. At the same time, the longitudinal and crossbeams can also restrict the position of photovoltaic panels during transportation, simplifying the steps of stacking photovoltaic panels during transportation and thus reducing damage to photovoltaic panels caused by improper stacking during transportation.

[0008] Furthermore, friction strips are fixedly connected to the sidewalls of the slide groove, and the friction strips are all made of elastic material.

[0009] Beneficial effects: The friction strip design in this solution increases the friction between the chute and the adjacent longitudinal beams, thereby reducing the risk of microcracks in the photovoltaic panels caused by sliding between the longitudinal beams due to inertia during transportation.

[0010] Furthermore, the adjustment assembly also includes several support rods, all of which are installed on the crossbeam or the keel. One end of the support rod near any top wall is hinged to the damping ball of the top wall, and the output end of the support rod is hinged to the adjacent photovoltaic panel sidewall via a detachable hinge.

[0011] Beneficial effects: Compared with existing technologies, this solution, through the design of support rods, allows users to adjust the angle between the photovoltaic panels and the horizontal plane based on real-time sunlight conditions during and after installation, thereby improving power generation efficiency.

[0012] Furthermore, baffles are provided on the bottom wall near the fixed column, and the baffles are used to restrict the rotation of adjacent fixed columns.

[0013] Beneficial effects: The design of the baffle in this solution restricts the rotation of the fixed column, reducing the risk of damage to the device caused by collisions between the fixed column and external obstacles during transportation due to external forces or improper handling. It also reduces the transfer of kinetic energy generated by the collision of the fixed column to the photovoltaic panel, thus preventing damage to the photovoltaic panel.

[0014] Furthermore, each of the friction strips has a cavity, and each cavity is filled with fluid. Each of the longitudinal beams has a push plate fixedly connected to one end near the keel.

[0015] Beneficial effects: This solution utilizes the chamber and fluid configuration to leverage the principle that when kinetic energy is rapidly transferred to the fluid, turbulence is formed, significantly increasing the resistance applied to the push plate. This distinguishes whether the longitudinal beam movement is a routine adjustment by the operator and provides greater resistance to the movement of the longitudinal beam when the longitudinal beam movement is not a routine adjustment by the operator.

[0016] Furthermore, the fluid is a shear-thickening fluid.

[0017] Beneficial effects: This solution uses a shear-thickening fluid. Compared with solutions using other fluids, the fluid in this solution experiences internal particle friction when the pusher plate's motion changes rapidly, further increasing the resistance applied to the pusher plate by the fluid.

[0018] Furthermore, the adjustment assembly also includes a damping hinge, wherein the fixed page of the damping hinge is fixedly connected to the keel, and the movable page of the damping hinge is detachably connected to the keel.

[0019] Beneficial effects: This solution utilizes damping hinges to detachably connect two identical devices, and the photovoltaic panels mounted on the keel are shielded and protected, further reducing the probability of damage during transportation. Furthermore, compared to solutions using ordinary hinges, damping hinges reduce relative rotation between the two devices due to inertia during transportation, further improving the stability of the transport process.

[0020] Furthermore, torsion springs are fitted at the hinge joints between the fixed column and the longitudinal beam.

[0021] Beneficial effects: The design of the torsion spring in this solution further simplifies the installation steps of the device compared with the existing technology. The design of the torsion spring also makes the movement of the fixed column more intense, which makes it easier for the operator to judge whether the longitudinal beam has been adjusted to the appropriate position based on the movement of the fixed column.

[0022] Furthermore, a number of partitions are fixedly connected to the side wall of the chamber, and the partitions are arranged at an angle to the side wall of the chamber.

[0023] Beneficial effects: The inclined partition design in this scheme divides the chamber by partitions, reducing the impact of gravity during transportation. This causes the fluid to accumulate at the bottom of the chamber, reducing the fluid's effect on hindering the movement of the push plate. At the same time, the inclined arrangement also makes the volume of the space formed by the push plate, partitions, and chamber sidewalls shrink as the push plate moves upward, further increasing the difficulty for the push plate to continue moving upward.

[0024] Furthermore, the sidewalls of the fixed columns are detachably connected to the sidewalls of the adjacent longitudinal beams.

[0025] Beneficial effects: By detachably connecting the side wall of the fixed column to the side wall of the adjacent longitudinal beam, the fixed column can maintain a fixed relative position with the longitudinal beam after rotating away from the baffle to a position perpendicular to the longitudinal beam. This prevents the fixed column from rotating during installation and affecting the operator's work. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explaining the utility model only and are not intended to limit the utility model. It should be noted that this utility model is already in the actual research and development stage.

[0029] Example 1 like Figures 1 to 4As shown, this embodiment includes a keel 1, on which an adjustment assembly is provided. The adjustment assembly includes several longitudinal beams 2, and several transverse beams 3 are welded and fixed to the side walls of each longitudinal beam 2. The side walls of the transverse beams 3 and the top wall of the keel 1 are all provided with slots, and photovoltaic panels 4 are provided within each slot. The photovoltaic panels 4 are detachably connected to the side walls of the slots by bolts. Sliding grooves are provided on the side walls of the keel 1 and the longitudinal beams 2 near adjacent longitudinal beams 2, and the longitudinal beams 2 slide against the adjacent side walls through the sliding grooves. A fixed column 22 is hinged to the bottom of each longitudinal beam 2, and a clamp 23 is provided at the bottom end of each fixed column 22. The clamp 23 used in this embodiment is model JX-JJ011-B, and the clamp 23 is detachably connected to the bottom end of the fixed column 22 by bolts. A baffle 12 is integrally formed on the bottom wall of the longitudinal beams 2 and the keel 1 near the fixed column 22, and the baffle 12 is used to restrict the rotation of adjacent fixed columns 22.

[0030] Friction strips 24 are bonded and fixed to the sidewalls of the slide grooves, and the friction strips 24 are all made of elastic material.

[0031] The adjustment assembly also includes a damping hinge 11, the fixed page of which is fixedly connected to the keel 1, and the movable page of which is detachably connected to the keel 1.

[0032] The specific implementation method is as follows: When using this solution, select a reasonable number of photovoltaic panels 4 and their installation positions according to the dimensions of the photovoltaic power generation module installation environment. Select a reasonable number of crossbeams 3 according to the number of photovoltaic panels 4 and their installation positions, and assemble the crossbeams 3 with the keel 1. Then, according to the installation position requirements of the photovoltaic panels 4, install the photovoltaic panels 4 onto the keel 1 or crossbeams 3 with bolts. Then push the longitudinal beams 2, so that the longitudinal beams 2 drive the crossbeams 3 and the photovoltaic panels 4 to move until the distance between the crossbeams 3 is reduced to the shortest distance. During this process, the photovoltaic panels 4 gradually move to the bottom of the adjacent photovoltaic panels 4. After the longitudinal beams 2 have moved, all the photovoltaic panels 4 have moved to the bottom of the keel 1.

[0033] The operator then connects the two keels 1 together using damping hinges 11 and rotates the damping hinges 11 to bring the top walls of the two keels 1 closer together. At this point, the assembly of the photovoltaic power generation module is completed, and the operator can then pack and transport the photovoltaic power generation module.

[0034] Upon arrival at the installation site, operators can use cranes or other equipment to hoist the device to the installation position. Then, they pull the longitudinal beam 2 in the opposite direction. As the distance between the crossbeams 3 gradually increases, the photovoltaic panel 4 is gradually exposed. At this point, due to the restriction of the baffle 12, the fixing column 22 cannot rotate downwards under gravity before the distance between the crossbeams 3 reaches its maximum. Once the distance between the longitudinal beams 2 reaches its maximum, the fixing column 22 rotates under gravity. Depending on the installation requirements of the photovoltaic panel 4, if a solution using clamps 23 is available, such as a corrugated steel roof, the operator can use clamps 23 to fix the fixing column 22 to the corrugated steel roof. Then, as the longitudinal beam 2 is pulled, the fixing column 22 is gradually fixed until the installation of the photovoltaic panel 4 is complete. If the installation plan involves using bolts or cement casting to install the photovoltaic panel 4 on a concrete foundation, the operator removes the clamps 23 from the fixing column 22 and fixes the fixing column 22 sequentially according to the installation plan until the installation of the photovoltaic panel 4 is complete.

[0035] Compared to existing technologies, this solution, through the design of the chute and longitudinal beam 2, allows operators to fold the photovoltaic power generation modules by changing the length of the longitudinal beam 2 entering the chute. Compared to existing technologies, this solution enables pre-installation of the photovoltaic power generation modules in the factory through folding, significantly reducing subsequent construction steps and lowering the professional skill requirements for operators during installation. Simultaneously, the longitudinal beam 2 and crossbeam 3 used in this solution protect and secure the photovoltaic panels 4 during transportation. Compared to traditional photovoltaic panel 4 transportation methods, the longitudinal beam 2, crossbeam 3, and keel 1 in this solution provide a certain degree of protection for the photovoltaic panels 4, reducing the probability of damage during transportation. Furthermore, since the photovoltaic panels 4 naturally present a vertical stacked state after folding, this solution meets the transportation requirements of traditional methods. The stacking process is simple and quick, requires minimal operator skill, and is less prone to damage caused by improper stacking.

[0036] Meanwhile, the design of the friction strip 24 in this solution increases the friction between the crossbeam 3 and the slide, thereby increasing the resistance of the crossbeam 3 during the sliding process. This reduces the risk of the crossbeam 3 moving due to the bumps of ships or vehicles during transportation, which could lead to microcracks in the photovoltaic panel 4.

[0037] Example 2 The difference from the above embodiment is that: each friction strip 24 has a cavity 241, and each cavity 241 is filled with fluid; each end of the crossbeam 3 away from the longitudinal beam 2 is welded and fixed with a push plate 21; the fluid is a shear thickening fluid; and a number of partitions 242 are bonded and fixed to the side wall of the cavity 241, with the partitions 242 arranged obliquely to the side wall of the cavity 241.

[0038] The specific implementation method is as follows: During the use of this scheme, as the longitudinal beam 2 slides relative to the slide groove, the longitudinal beam 2 drives the push plate 21 to move. The push plate 21 squeezes the friction strip 24, causing the chamber 241 to deform. When the operator moves the crossbeam 3 through the longitudinal beam 2, the longitudinal beam 2 moves slowly. Due to inertia and the surface tension of the fluid, the fluid flows slowly in the chamber 241. At this time, the fluid has little influence on the movement of the push plate 21. However, when the longitudinal beam 2 changes its motion state in a very short time due to inertia and other factors, the pushing work is intense, causing the fluid to move and form turbulence. At this time, the resistance exerted by the fluid on the push plate 21 is dominated by inertial resistance, and the kinetic energy of the push plate 21 is greatly absorbed during the formation of turbulence. The resistance exerted by the fluid on the push plate 21 increases significantly, hindering the continued movement of the push plate 21.

[0039] This solution, through fluid design, further reduces the possibility of microcracks in the photovoltaic panel 4 caused by sudden changes in the motion state of the longitudinal beam 2 during transportation or installation. Compared with existing technologies, this solution can determine whether the current motion of the longitudinal beam 2 is a routine adjustment performed by the operator based on its motion state. When it is not a routine adjustment, it provides greater resistance to the movement of the longitudinal beam 2, reducing the probability of the longitudinal beam 2 moving. At the same time, when it is a routine adjustment, it can also avoid providing excessive assistance to the movement of the longitudinal beam 2, which would affect the operator's work.

[0040] In this design, by using a shear-thickening fluid, compared to using fluids such as water, when the kinetic energy of the pusher plate 21 is transferred to the fluid, the particles inside the fluid rub against each other, which further increases the resistance applied by the fluid to the pusher plate 21, further restricting the continued movement of the pusher plate 21 and improving the safety of the photovoltaic panel 4 during the transportation of this device.

[0041] Meanwhile, the design of the partition 242 in this solution separates the chamber 241, effectively reducing the downward movement and accumulation of fluid at the top of the photovoltaic panel 4 due to gravity and other factors during transportation. This reduces the likelihood of fluid accumulation at the bottom of the chamber 241 affecting the movement of the buffer push plate 21. Furthermore, by arranging the partition 242 at an angle, the volume of the area formed by the partition 242, the side wall of the chamber 241, and the push plate 21 gradually decreases as the push plate 21 pushes the fluid upward, increasing the difficulty for the push plate 21 to move the fluid and further hindering its movement.

[0042] Example 3 The difference from the above embodiments is that the adjustment assembly further includes several support rods 5. In this embodiment, the support rods 5 are angle-adjustable gas springs. The support rods 5 are all installed on the crossbeam 3 or the keel 1. The end of the support rod 5 near any top wall is hinged to the damping ball of the top wall. The output end of the support rod 5 is hinged to the side wall of the adjacent photovoltaic panel 4 through a detachable hinge.

[0043] A torsion spring is fitted at the hinge joint between the fixed column 22 and the longitudinal beam 2. One end of the torsion spring is welded to the fixed column 22 and the other end is welded to the longitudinal beam 2. The side wall of the fixed column 22 is detachably connected to the side wall of the adjacent longitudinal beam 2 by a snap fastener.

[0044] The specific implementation method is as follows: Since the duration and area of ​​sunlight exposure to the photovoltaic panel 4 have a significant impact on the power generation efficiency of the photovoltaic power generation module, during the use of this solution, the operator can determine whether the photovoltaic panel 4 needs to be tilted based on the construction location. Under the normal installation scheme parallel to the installation plane, if the photovoltaic panel 4 cannot be fully exposed to sunlight, or if the angle between the photovoltaic panel 4 and the sunlight is too large, resulting in excessive reflection loss and affecting light energy absorption, the operator can remove the photovoltaic panel 4 from the crossbeam 3 or keel 1, then adjust the length of the support rod 5 and the angle between the support rod 5 and the horizontal plane, and then use the detachable... The detachable hinge fixes the photovoltaic panel 4 at the corresponding position, enabling adjustment of the angle of the photovoltaic panel 4. At the same time, since the support rod 5 and other structures used in this solution adjust the angle of the photovoltaic panel 4, compared with the existing technology, users can make corresponding adjustments to the photovoltaic panel 4 according to changes in the usage scenario after the photovoltaic power generation module is installed. For example, in summer when there is sufficient sunlight, the angle between the photovoltaic panel 4 and the horizontal plane can be reduced by adjusting the support rod 5 to improve power generation efficiency. When there is insufficient sunlight in winter, the angle between the photovoltaic panel 4 and the horizontal plane can be increased to compensate for the angle of the sun and reduce the loss of power generation.

[0045] Meanwhile, through the design of the torsion spring in this solution, when the distance between the crossbeams 3 reaches the maximum distance during the sliding process of the longitudinal beam 2, the fixed column 22 disengages from the baffle 12, the limiting effect of the baffle 12 on the fixed column 22 is released, the torsion spring resets, and drives the fixed column 22 to rotate downward, moving the fixed column 22 to a position perpendicular to the longitudinal beam 2, thereby further reducing the construction steps for operators. In addition, this solution also uses the method of detachably connecting the side wall of the fixed column 22 to the side wall of the longitudinal beam 2. When the torsion spring drives the fixed column 22 to move to a position perpendicular to the longitudinal beam 2, the fixed column 22 engages with the side wall of the longitudinal beam 2, thereby restricting the position of the fixed column 22 and helping operators to fix the fixed column 22 to the installation position in the subsequent steps.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
