Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a photovoltaic sunroom. [Background Technology]

[0002] Most existing photovoltaic (PV) greenhouses use a fixed installation method. This method results in a fixed tilt angle for the PV modules, which is often not optimal, failing to effectively utilize the solar energy radiated onto the module surface. Furthermore, during snowfall or strong winds, the tilt angle cannot be adjusted to mitigate the impact of snow accumulation and wind on the stability of the power generation system. Additionally, the fixed tilt angle prevents adjustment during rainfall to enhance the self-cleaning capabilities of the PV modules. Even those PV greenhouses designed with tilt adjustment functions often suffer from structural complexity and inconvenient adjustment.

[0003] Chinese patent CN116733155A discloses a photovoltaic solar greenhouse with an adjustable roof angle, including support columns, a roof frame, and an inclined roof. The roof frame includes multiple sets of adjustable support frames spaced apart below the inclined roof. Each adjustable support frame includes multiple tripods arranged along the inclined direction of the roof. Each tripod is formed by a base rod, a vertical rod, and a diagonal rod, creating a right-angled triangle structure. The diagonal rods of all the tripods on the adjustable support frame form a supporting beam for the inclined roof. The diagonal rods and vertical rods of the tripods are telescopic structures, and the two ends of the diagonal rods are hinged to the base rod and the vertical rod, respectively, to adjust the angle of the diagonal rods by extending and retracting the vertical rods. However, due to the large number of diagonal and vertical rods in the entire photovoltaic solar greenhouse, adjusting the angle of the diagonal rods by extending and retracting the vertical rods is quite cumbersome. [Utility Model Content]

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a photovoltaic sunshade support system with adjustable tilt angle, which can realize rapid adjustment of tilt angle.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An adjustable-angle photovoltaic (PV) solar greenhouse support system includes a support assembly, a scissor lift mechanism, and a scissor lift drive assembly. The support assembly includes front and rear columns arranged correspondingly, and a load-bearing component connecting the two columns. The scissor lift mechanism is located between the two columns and includes a fixed end fixed to the front column and a free end with a movable gap between it and the rear column. The load-bearing component is movably connected to the scissor lift mechanism. The scissor lift arm of the scissor lift mechanism is connected to the PV module and adjusts the tilt angle of the PV module when the scissor lift mechanism extends or retracts. The scissor lift drive assembly is used to drive the scissor lift mechanism to extend or retract.

[0007] Preferably, the scissor mechanism includes several sets of intermediate scissor arms and end scissor arms. Each set of intermediate scissor arms has two intermediate scissor arms, which are hinged together at the middle. The ends of the intermediate scissor arms are hinged to the ends of the adjacent set of intermediate scissor arms. Each set of end scissor arms has two end scissor arms, with the first end of each end scissor arm hinged and the other end hinged to the end of the adjacent set of intermediate scissor arms.

[0008] Preferably, at least two scissor lift mechanisms are arranged side by side in the transverse direction, and the upper half of the middle scissor lift arm and the upper end scissor lift arm included in the at least two scissor lift mechanisms are vertically connected to the purlin, on which photovoltaic modules are installed.

[0009] Preferably, the scissor lift drive assembly drives one of the scissor lift mechanisms; and / or, the scissor lift drive assembly includes a first traction cable and a second traction cable, the first traction cable being connected to the free end of the scissor lift mechanism and used to pull the free end of the scissor lift mechanism forward to retract the scissor lift mechanism and increase the tilt angle of the photovoltaic module, and the second traction cable being connected to the free end of the scissor lift mechanism and used to pull the free end of the scissor lift mechanism backward to extend the scissor lift mechanism and decrease the tilt angle of the photovoltaic module.

[0010] Preferably, the first traction cable is driven by a first traction motor, and the second traction cable is driven by a second traction motor.

[0011] Preferably, the output shaft of the first traction motor is connected to a first drum, and the first drum is connected to a first traction cable; the output shaft of the second traction motor is connected to a second drum, and the second drum is connected to a second traction cable.

[0012] Preferably, the scissor mechanism further includes limit sliders spaced apart along the front-rear direction, through which the first traction cable moves.

[0013] Preferably, the limiting slider is provided with two clamping pulleys, and the first traction steel cable passes through the middle of the two clamping pulleys.

[0014] Preferably, the load-bearing component is a load-bearing steel cable, and the two ends of the load-bearing steel cable are respectively fixed to two corresponding front and rear columns. The scissor mechanism also includes a limiting slider that is spaced apart along the front and rear direction, and the load-bearing steel cable moves through the limiting slider.

[0015] Preferably, the fixed end of the scissor mechanism is connected to a fixed seat, and the fixed seat is fixed to the front column.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. This utility model provides a photovoltaic solar greenhouse support system with adjustable tilt angle, including a support assembly, a scissor mechanism, and a scissor drive assembly. The support assembly includes front and rear columns arranged correspondingly, and a load-bearing component connecting the two corresponding columns. The scissor mechanism is located between the two corresponding columns, and the scissor drive assembly drives the scissor mechanism to extend and retract. Considering the structural characteristics of the scissor mechanism, when placed horizontally, the scissor mechanism can extend and retract horizontally. Since the scissor arms of the scissor mechanism are inclined, the tilt angle of the scissor arms can change during extension and retraction. Therefore, by connecting the photovoltaic modules to the scissor arms of the scissor mechanism, the scissor drive assembly drives the scissor mechanism to extend and retract, synchronously adjusting the tilt angle of the photovoltaic modules during the extension and retraction of the scissor mechanism.

[0018] The support assembly is used to support the scissor lift mechanism. The front and rear columns are set correspondingly, and a scissor lift mechanism is set between them. Since the scissor lift mechanism is supported by columns, only the fixed end of the scissor lift mechanism is fixed to the front column, and there is a movable gap between the free end and the rear column to leave space for the scissor lift mechanism to extend and retract. Therefore, a load-bearing component is required to support the scissor lift mechanism. Moreover, in order to ensure that the scissor lift mechanism can extend and retract relative to the load-bearing component, the load-bearing component is movably connected to the scissor lift mechanism, so that while supporting the scissor lift mechanism, it will not affect the extension and retraction of the scissor lift mechanism.

[0019] Because the scissor mechanism has the characteristics of a parallelogram linkage mechanism, it can achieve a large adjustment range while ensuring stability. Therefore, when combined with the support of the support components, it can not only ensure the stability of the photovoltaic modules installed on it, but also achieve a large range of adjustment of the tilt angle of the photovoltaic modules.

[0020] Furthermore, the scissor drive component is used to drive the extension and retraction of the scissor mechanism. For example, only one scissor mechanism can be driven. At the same time, all photovoltaic modules on the photovoltaic solar canopy support system can achieve synchronous adjustment of the tilt angle, thus enabling rapid adjustment of the tilt angle.

[0021] 2. Multiple scissor lift mechanisms work together to install photovoltaic modules. At least two scissor lift mechanisms are arranged side by side in the transverse direction, and the upper half of the middle scissor arm and one of the upper end scissor arms in the at least two scissor lift mechanisms are perpendicularly connected to the purlin. The photovoltaic modules are installed on the purlin. In this way, multiple photovoltaic modules are installed on multiple scissor lift mechanisms to form a whole, and the tilt angle can be adjusted as a whole.

[0022] Furthermore, the scissor lift drive assembly can drive only one scissor lift mechanism, such as the scissor lift mechanism in the middle laterally. Since all scissor lift mechanisms are connected together by purlins, as long as one scissor lift mechanism is driven by the scissor lift drive assembly to extend or retract, all other scissor lift drive assemblies can extend or retract synchronously.

[0023] 3. The scissor lift drive assembly includes a first traction cable and a second traction cable. The first traction cable is connected to the free end of the scissor lift mechanism and is used to pull the free end of the scissor lift mechanism forward to retract the scissor lift mechanism and increase the tilt angle of the photovoltaic module. The second traction cable is connected to the free end of the scissor lift mechanism and is used to pull the free end of the scissor lift mechanism backward to extend the scissor lift mechanism and decrease the tilt angle of the photovoltaic module. Cables are used for traction because steel cables are flexible, have high strength, and can withstand significant tension.

[0024] 4. Since the scissor lift mechanism requires considerable effort to extend and retract the photovoltaic modules after installation, a manually operated scissor lift is unsuitable. Therefore, a motor is used as the drive source for the scissor lift. Specifically, the first traction cable is driven by a first traction motor, and the second traction cable is driven by a second traction motor. The first and second traction motors operate simultaneously but in opposite directions. Furthermore, the output shaft of the first traction motor is connected to a first drum, which is connected to the first traction cable; similarly, the output shaft of the second traction motor is connected to a second drum, which is connected to the second traction cable. Using drums facilitates the winding and releasing of the traction cables.

[0025] 5. The scissor mechanism is provided with limit sliders at intervals along the front-to-back direction. The limit sliders are equipped with two clamping pulleys. The first traction steel cable passes through the middle of the two clamping pulleys. Therefore, the friction force during the traction process is small, ensuring the flexible extension and retraction of the scissor mechanism.

[0026] 6. The load-bearing components utilize load-bearing steel cables, which flexibly pass through the limiting slider to provide support for the scissor lift mechanism. The load-bearing steel cables are made of a flexible material with high strength, capable of withstanding significant tension. Therefore, they can withstand the weight of the scissor lift mechanism and the photovoltaic modules installed on it, as well as transmitted vibrations and external loads from natural environments such as wind, ice, rain, and snow.

[0027] 7. The fixed end of the scissor mechanism is connected to a fixed seat, which is fixed to the front column to ensure that the fixed end of the scissor mechanism is reliably fixed.

[0042] To facilitate adjusting the angle of the photovoltaic modules in the photovoltaic greenhouse to achieve the optimal power generation tilt angle, refer to... Figures 1 to 6 As shown, this embodiment provides a photovoltaic solar greenhouse support system with adjustable tilt angle, including a support component 3, a scissor mechanism 1, and a scissor drive component 2. The support component 3 includes front and rear rows of columns arranged correspondingly, and a load-bearing member connecting the two corresponding columns. The front rows of columns include a row of front columns 31 spaced laterally, and the rear rows of columns include a row of rear columns 32 spaced laterally. The number of front columns 31 and rear columns 32 is equal, and they are arranged correspondingly. A scissor mechanism 1 is provided between the corresponding front and rear columns 31 and 32. Therefore, the scissor mechanism 1 is located between the two corresponding columns and includes a fixed end fixed to the front column 31 and a free end with a movable gap between it and the rear column 32. The load-bearing member is movably connected to the scissor mechanism 1. The scissor arms of the scissor mechanism 1 are connected to the photovoltaic module 4, and adjust the tilt angle of the photovoltaic module when the scissor mechanism 1 extends or retracts. The scissor drive component 2 is used to drive the extension and retraction of the scissor mechanism 1.

[0043] The scissor lift mechanism is existing technology. Based on its structural characteristics, when placed horizontally, the scissor lift mechanism can extend and retract horizontally. Because the scissor arms are tilted, the tilt angle of the scissor arms can change during extension and retraction. Therefore, by connecting the photovoltaic module to the scissor arms of the scissor lift mechanism, the scissor lift drive component drives the scissor lift mechanism to extend and retract, synchronously adjusting the tilt angle of the photovoltaic module during the extension and retraction of the scissor lift mechanism.

[0044] The support assembly is used to support the scissor lift mechanism. The front and rear columns are set correspondingly, and a scissor lift mechanism is set between them. Since the scissor lift mechanism is supported by columns, only the fixed end of the scissor lift mechanism is fixed to the front column, and there is a movable gap between the free end and the rear column to leave space for the scissor lift mechanism to extend and retract. Therefore, a load-bearing component is required to support the scissor lift mechanism. Moreover, in order to ensure that the scissor lift mechanism can extend and retract relative to the load-bearing component, the load-bearing component is movably connected to the scissor lift mechanism, so that while supporting the scissor lift mechanism, it will not affect the extension and retraction of the scissor lift mechanism.

[0045] Because the scissor lift mechanism has the characteristics of a parallelogram linkage mechanism, it can achieve a large adjustment range while ensuring stability. Therefore, in conjunction with the support components, it can ensure the stability of the photovoltaic modules installed on it, and also allow for a wide range of tilt angle adjustments for the photovoltaic modules. Moreover, the scissor lift drive component drives the extension and retraction of the scissor lift mechanism, and all photovoltaic modules on the photovoltaic solar canopy support system can achieve synchronous tilt angle adjustments, thus enabling rapid tilt angle adjustments.

[0046] In conjunction with existing scissor lift mechanisms, the scissor lift mechanism 1 includes several sets of intermediate scissor lift arms 11 and end scissor lift arms 12. Each end of the scissor lift mechanism 1 has one set of end scissor lift arms 12 at both ends. Between the two sets of end scissor lift arms 12, several sets of intermediate scissor lift arms 11 are provided, for example, three, four, or even more sets. Each set of intermediate scissor lift arms has two intermediate scissor lift arms, with the first end of each end scissor lift arm hinged to the middle section, and the end of each intermediate scissor lift arm hinged to the end of the adjacent set of intermediate scissor lift arms. Each set of end scissor lift arms has two end scissor lift arms, with the first end of each end scissor lift arm hinged to the second end of the adjacent set of intermediate scissor lift arms. A rotating pin is provided at the hinge point of the scissor lift arms.

[0047] It is understood that multiple scissor lift mechanisms work together to install photovoltaic modules. Specifically, at least two scissor lift mechanisms 1 are arranged side by side in the transverse direction, and the upper half of the middle scissor lift arm and one upper end scissor lift arm included in the at least two scissor lift mechanisms 1 are perpendicularly connected to the purlin 41, on which the photovoltaic modules 4 are installed. Figure 1 As shown, the two rows of photovoltaic modules are arranged in a V-shape along the front-to-back direction. In this way, multiple photovoltaic modules are installed on multiple scissor lift mechanisms to form a whole, which can be adjusted in tilt as a whole.

[0048] It is understood that the scissor lift drive assembly 2 can drive only one scissor lift mechanism, such as the scissor lift mechanism in the middle laterally. Since all scissor lift mechanisms are connected together by purlins, as long as one scissor lift mechanism is driven by the scissor lift drive assembly to extend or retract, all other scissor lift drive assemblies can extend or retract synchronously. Of course, each scissor lift mechanism can also be driven by a corresponding scissor lift drive assembly. When adjusting the tilt angle, all scissor lift drive assemblies need to operate synchronously to ensure that all scissor lift mechanisms extend or retract synchronously.

[0049] In some embodiments, the scissor lift drive assembly 2 includes a first traction cable 22 and a second traction cable 24. The first traction cable 22 is connected to the free end of the scissor lift mechanism 1 and is used to pull the free end of the scissor lift mechanism forward to retract the scissor lift mechanism and increase the tilt angle of the photovoltaic module. The second traction cable 24 is connected to the free end of the scissor lift mechanism 1 and is used to pull the free end of the scissor lift mechanism backward to extend the scissor lift mechanism and decrease the tilt angle of the photovoltaic module. Cables are used for traction because steel cables are flexible, have high strength, and can withstand significant tension.

[0050] Since the scissor lift mechanism requires considerable effort to extend and retract the photovoltaic modules after installation, a manually operated scissor lift drive is unsuitable. Therefore, a motor is used as the drive source for the scissor lift drive. In this embodiment, the first traction cable 22 is driven by the first traction motor 21, and the second traction cable 24 is driven by the second traction motor 23. The output shaft of the first traction motor is connected to a first drum, which is connected to the first traction cable; the output shaft of the second traction motor is connected to a second drum, which is connected to the second traction cable. The use of drums facilitates the winding and releasing of the traction cables. The first traction motor 21 and the second traction motor 23 operate simultaneously but in opposite directions. Specifically, the first traction cable 22 pulls forward on the free end of the scissor lift mechanism, allowing the second traction cable 24 to release the free end of the scissor lift mechanism forward during retraction; conversely, the second traction cable 24 pulls backward on the free end of the scissor lift mechanism, allowing the first traction cable 22 to release the free end of the scissor lift mechanism backward during extension.

[0051] Furthermore, the scissor mechanism 1 also includes limit sliders 14 spaced apart along the front-rear direction, through which the first traction cable 22 movably passes. The limit sliders 14 are equipped with two clamping pulleys 141, and the first traction cable 22 passes through the middle of the two clamping pulleys 141. The limit sliders can be positioned on the lateral side of the scissor mechanism 1, corresponding to the hinge point of the two scissor arms. Because the first traction cable passes through the middle of the two clamping pulleys on the limit slider, the frictional force during traction is relatively small, ensuring the flexible extension and retraction of the scissor mechanism.

[0052] The first traction motor 21 can be installed at the bottom of the front column at the corresponding position. A limiting slider 14 can be installed at the top of the front column. At the same time, an electrical control box 25 is installed in the middle of the column, which is connected to the first traction motor 21 and the second traction motor 23 for controlling the first traction motor 21 and the second traction motor 23. The second traction motor 23 can be installed at the bottom of the rear column at the corresponding position. A limiting slider 14 can be installed at the top of the rear column.

[0053] In some embodiments, the load-bearing component is a load-bearing steel cable 33, with its two ends fixed to two corresponding front and rear columns. The scissor mechanism 1 also includes limiting sliders 14 spaced apart along the front-rear direction, through which the load-bearing steel cable 33 moves. The load-bearing steel cable is made of a soft material with high strength, capable of withstanding significant tension. Therefore, it can bear the weight of the scissor mechanism and the photovoltaic modules installed on it, as well as the transmitted vibrations and external loads from natural environments such as wind, ice, rain, and snow. It is understood that this limiting slider has the same structure as the limiting slider through which the first traction steel cable passes, but they are not the same limiting slider. Because each scissor mechanism needs to be connected to the load-bearing steel cable, a set of limiting sliders must be provided to connect to the load-bearing steel cable. However, for the scissor mechanism that connects to the scissor drive assembly, it needs to connect both the load-bearing steel cable and the first traction steel cable. Therefore, a set of limiting sliders can be connected to each side laterally, with one set of limiting sliders connected to the load-bearing steel cable and the other set connected to the first traction steel cable 22.

[0054] Furthermore, the fixed end of the scissor lift mechanism 1 is connected to a fixed seat 13, which is fixed to the front column 31. Specifically, the fixed seat 13 is U-shaped, with its opening facing the fixed end of the scissor lift mechanism. The first ends of the two scissor arms 12 are hinged to the fixed seat 13. The fixed seat can be fixed to the rear top of the front column with bolts to ensure that the fixed end of the scissor lift mechanism is reliably fixed.

[0055] Both the uprights and the scissor arms can be made of square steel tubing. Of course, other structural profiles can also be used, including zinc-aluminum-magnesium alloys. This not only results in lower material costs but also excellent corrosion resistance, high strength, and a long service life.

[0056] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
