Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation support technology, and in particular to a photovoltaic power generation device with an easy-to-install structure. Background Technology

[0002] Solar photovoltaic (PV) power generation is a technology that uses solar cells to directly convert sunlight into electricity based on the photovoltaic effect. With the increasing popularity of the concepts of clean energy and sustainable resource development, safe and environmentally friendly PV power generation technology has been widely promoted and used in existing technologies. Typically, outdoor PV power generation equipment consists of solar panels and support devices. The support devices are used to mount the solar panels so that they face the sun to receive sunlight and generate PV power.

[0003] To improve the stability of photovoltaic power generation, it is necessary to ensure the stability of the solar panel support. However, the support devices used to support solar panels for photovoltaic power generation in the existing technology are usually composed of a frame structure. The frame-shaped support device is usually composed of multiple disassembled parts, which are assembled when in use and stored separately when not in use. Although this can improve the convenience of storage and transportation of the support device, the assembly of the relatively scattered parts is cumbersome and it is difficult to quickly assemble the support for the solar panel when in use. This not only significantly increases the labor cost of photovoltaic power generation installation, but also affects the installation efficiency.

[0004] Therefore, a photovoltaic power generation device with an easy-to-install structure is proposed to solve some of the problems existing in the above-mentioned prior art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing photovoltaic power generation technology, such as the difficulty in assembling support devices, which leads to high installation costs and low installation efficiency.

A vertically arranged second screw is rotatably installed inside the second main rod, and a second threaded sleeve that is threadedly connected to the second screw is slidably installed inside the first main rod. The second threaded sleeve is fixedly connected to the second sliding sleeve through the through groove.

[0009] Preferably, the connector includes a bearing seat rotatably connected to the top end of the first side support rod, and a first torsion spring is installed at the rotatable connection between the bearing seat and the top end of the first side support rod. A C-shaped clip is installed on the outer side of the bearing seat. The bottom foot is rotatably connected to the bottom end of the second side support rod, and a second torsion spring is installed at the rotatable connection between the bottom foot and the bottom end of the second side support rod.

[0010] Preferably, the C-shaped clamp is rotatably connected to the shaft seat, and the rotation axis of the C-shaped clamp is perpendicular to the rotation axis of the shaft seat.

[0011] Preferably, when the first main rod and the second main rod are vertically aligned, there is a 45° angle between the rotation axis of the first side support rod and the rotation axis of the first hinge platform on the horizontal plane.

[0012] Preferably, a first bevel tooth is fixedly installed at the bottom end of the first screw and disposed within the first hinge platform, and a second bevel tooth is fixedly installed at the top end of the first screw and disposed within the second hinge platform, and a third bevel tooth is engaged between the first bevel tooth and the second bevel tooth.

[0013] Preferably, the third bevel gear is rotatably mounted between the first hinge platform and the second hinge platform, and the third bevel gear is coaxially arranged with the rotation axis of the first hinge platform and the second hinge platform.

[0014] Preferably, a shaft is fixedly installed inside the first hinge platform, coaxially arranged with its rotation axis, and a shaft sleeve is movably sleeved on the outside of the shaft. A straight spring elastically supports the shaft and the shaft sleeve inside the shaft sleeve, and a third bevel gear is rotatably installed at the end of the shaft sleeve.

[0015] Preferably, a first servo motor is fixedly installed on the outer end wall of the second hinge platform, and the drive shaft of the first servo motor is connected to a worm gear transmission. A second servo motor is fixedly installed at the bottom of the second main rod, and the drive shaft of the second servo motor is connected to a second screw transmission.

[0016] Preferably, a support platform is slidably mounted on the top end of the first main rod, and a bolt is threaded onto the outer end wall of the support platform, with the bolt pointing perpendicularly to the outer end wall of the first main rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) In this invention, by hinged four first side support rods around the bottom of the first main rod and four second side support rods around the top of the second main rod, and by sliding the first and second sliding sleeves and hinged the first and second hinge rods, the device can be used to install solar panels by simply driving the corresponding first and second hinge rods to move and support through the sliding of the first and second sliding sleeves. This makes it convenient to operate and can effectively improve the ease of solar panel installation, improve installation efficiency and reduce installation costs. It also makes it easy and stable for workers to install solar panels for photovoltaic power generation. At the same time, by rotating between the first and second hinge platforms and cooperating with the self-locking property of the meshing transmission between the worm and the worm wheel, the tilt angle of the solar panel can be flexibly adjusted and automatically fixed and stabilized, which helps to ensure the flexibility and efficiency of photovoltaic power generation.

[0019] (2) In this invention, by screwing the first threaded sleeve, which is fixedly connected to the first sliding sleeve, onto the first screw, and by screwing the second threaded sleeve, which is fixedly connected to the second sliding sleeve, onto the second screw, the movement control of the first and second sliding sleeves can be achieved through the rotation of the first and second screws, thereby flexibly controlling the unfolding angle of the first and second side support rods. With the meshing transmission of the first bevel teeth, the second bevel teeth, and the third bevel teeth, the rotation of the first and second screws can be carried out in coordination, which is beneficial to further improve the convenience and flexibility of the device when unfolding and using it. Furthermore, the meshing of the threads makes the device automatically remain stable after unfolding, making it convenient for the device to be used for the installation and support of solar panels of different sizes.

[0020] (3) In this invention, by rotating the top end of the shaft seat and the first side support rod, and rotating the bottom end of the foot and the second side support rod, the C-shaped clip can be stably attached to the bottom of the solar panel at different unfolding angles of the first side support rod and the first sliding sleeve, and the bottom foot can be stably attached to the ground, ensuring the stability of the device in actual use. At the same time, through the elastic support of the first torsion spring and the second torsion spring, the device can be folded and stored, and without being pushed by a large external force, the connecting parts and the bottom foot are all facing outward in an orderly manner, without shaking or colliding, which helps to ensure the stability of the device when it is folded and stored.

[0021] (4) In this invention, by setting the rotation axis of the first side support rod and the rotation axis of the first hinge platform to have a 45° angle on the horizontal plane, the four first side support rods above unfold into an X-shaped structure. The upper ends of the four first side support rods can be connected to the four corners of the bottom of the solar panel through corresponding connectors. With the support platform supporting from the middle of the bottom, a five-point support connection mode is formed, which can effectively improve the stability of the solar panel when supported by the device.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example: This example provides a photovoltaic power generation device with an easy-to-install structure. See [link to example]. Figure 1The diagram shows, specifically, a first main rod 1. Four vertically arranged first side support rods 101 are hinged around the lower outer end wall of the first main rod 1. A first sliding sleeve 102 is slidably fitted on the outer side of the first main rod 1. A first hinge rod 103 is hinged between the inner middle of the first side support rods 101 and the first sliding sleeve 102. A second main rod 2, located on the same straight line as the first main rod 1, is positioned below it. Four vertically arranged second side support rods 201 are hinged around the upper outer end wall of the second main rod 2. A second sliding sleeve 201 is slidably fitted on the outer side of the second main rod 2. 02. A second hinge rod 203 is hinged between the inner middle position of the second side support rod 201 and the second sliding sleeve 202. A connector 3 is installed at the top of the first side support rod 101. A foot 4 is installed at the bottom of the second side support rod 201. A first hinge platform 5 is fixedly installed at the bottom of the first main rod 1. A second hinge platform 501 rotatably connected to the first hinge platform 5 is fixedly installed at the top of the second main rod 2. A worm gear 502 coaxially arranged with its rotation axis is fixedly installed inside the first hinge platform 5. A worm 503 meshing with the worm gear 502 is rotatably installed inside the second hinge platform 501.

[0038] When transported and stored, the device is in a retracted state. Numerous surrounding first side support rods 101 are tightly attached to the outer end wall of the first main rod 1, and numerous surrounding second side support rods 201 are tightly attached to the outer end wall of the second main rod 2. This makes the device present a robust columnar structure. In the retracted state, the overall volume is small, which greatly reduces the space occupied. Moreover, the structure is regular and square after retraction, which is easy to stack and can effectively ensure the convenience of transporting and storing the device.

[0039] In actual use, the device requires deployment. The operator first deploys the lower second side support rod 201. Initially, the second sliding sleeve 202 is positioned above and outside the second main rod 2. The operator then controls the second sliding sleeve 202 to move downwards along the second main rod 2. This downward movement of the second sliding sleeve 202 causes the end of the second hinge rod 203 away from the second side support rod 201 to move downwards. Under the rotational support of the second hinge rod 203, numerous second side support rods 201 are supported and rotated. The lower ends of the second side support rods 201 unfold outwards away from the second main rod 2, ultimately allowing the second main rod 2 and the second side support rod 201 to unfold. The two side support rods 201 and the second sliding sleeve 202, together with the second hinge rod 203, form an unfolded umbrella-shaped structure. The workers can fix the lower end of the second side support rod 201 to the ground through the base 4 to install the device. With the base 4 fixed to the ground, the second main rod 2, the second side support rod 201, and the second hinge rod 203 form a triangular support structure. Two adjacent second side support rods 201, together with the ground, also form a triangular support structure. With the support stability of the triangular structure, the numerous second side support rods 201 after unfolding can provide structurally stable support force for the device.

[0040] Subsequently, the staff can unfold the first side support rod 101. In the initial state, the first sliding sleeve 102 is located below and outside the first main rod 1. The staff can control the first sliding sleeve 102 to move upward along the first main rod 1. The upward movement of the first sliding sleeve 102 drives the end of the first hinge rod 103 away from the first side support rod 101 to move upward. Under the rotational support of the first hinge rod 103, many first side support rods 101 are supported and rotated. The upper ends of the first side support rods 101 unfold outward away from the first main rod 1. Finally, the first main rod 1, the first side support rod 101, the first sliding sleeve 102, and the first hinge rod 103 form an inverted unfolding umbrella-shaped structure. After unfolding, the four first side support rods 101... The upper end of 01 is on the same horizontal plane. The staff can fix the solar panel to the top of the four first side support rods 101 through the connector 3 to complete the connection between the solar panel and the device. At this time, the first main rod 1, the first side support rods 101 and the first hinge rod 103 form a triangular support structure. The two adjacent first side support rods 101 and the solar panel also form a triangular support structure. With the support stability of the triangular structure, the many first side support rods 101 after unfolding can provide stable support for the solar panel installed above. After the device is unfolded, many mutually cooperating triangular structures are formed inside, which can effectively improve the stability of the solar panel when it is supported by the device.

[0041] In actual use, this device only needs to slide the first sliding sleeve 102 and the second sliding sleeve 202 to move the corresponding first hinge rod 103 and the second hinge rod 203 to support the movement, thereby unfolding the numerous surrounding first side support rods 101 and second side support rods 201. This allows for the installation of solar panels, making operation convenient and effectively improving the ease of solar panel installation. It facilitates workers to easily and stably install solar panels for photovoltaic power generation. When using this device to support solar panels for photovoltaic power generation, workers can adjust the first main rod by rotating the first hinge platform 5 and the second hinge platform 501. The tilt angle of the first and second main rods 1 and 2 supports the tilt angle of the solar panel above. During this process, the operator drives the worm gear 503 to rotate. Through the meshing between the worm gear 503 and the worm wheel 502, the worm wheel 502 is driven to rotate, which in turn drives the first hinge platform 5 to rotate relative to the second hinge platform 501, thus completing the angle adjustment operation. During the adjustment process, the self-locking property of the meshing transmission between the worm gear 503 and the worm wheel 502 ensures that the tilt angle of the solar panel is automatically fixed and stable after adjustment. The rotation adjustment ensures that the top of the solar panel can always face the sunlight, which is conducive to ensuring the stability and efficiency of photovoltaic power generation.

[0042] In the specific implementation process, such as Figure 2 and Figure 4 - Figure 6As shown, through grooves are provided on the outer end walls of the first main rod 1 and the second main rod 2. A vertically arranged first screw 104 is rotatably installed in the first main rod 1. A first threaded sleeve 105 that is threadedly connected to the first screw 104 is slidably installed in the first main rod 1. The first threaded sleeve 105 is fixedly connected to the first sliding sleeve 102 through the through groove. A vertically arranged second screw 204 is rotatably installed in the second main rod 2. A second threaded sleeve 205 that is threadedly connected to the second screw 204 is slidably installed in the first main rod 1. The second threaded sleeve 205 is fixedly connected to the second sliding sleeve 202 through the through groove.

[0043] In actual use, when controlling the movement of the first sliding sleeve 102, the operator can drive the first screw 104 to rotate. Through the threaded connection between the first screw 104 and the first screw sleeve 105, the rotation of the first screw 104 drives the first screw sleeve 105 to move within the first main rod 1. The through-slot connection between the first screw sleeve 105 and the first sliding sleeve 102 drives the first sliding sleeve 102 to move, thus controlling the unfolding of the numerous first side support rods 101 on the outer side of the first main rod 1. Similarly, when controlling the movement of the second sliding sleeve 202, the operator can drive the second screw 204 to rotate. Through the threaded connection between the second screw 204 and the second screw sleeve 205, the rotation of the second screw 204 drives the second screw sleeve 205 to move within the second main rod 2. The through-slot connection between the second screw sleeve 205 and the second sliding sleeve 202... The second sliding sleeve 202 is moved through the through groove, thereby controlling the unfolding of the numerous second side support rods 201 on the outer side of the second main rod 2. The first sliding sleeve 102 is moved by the threaded engagement between the first screw 104 and the first threaded sleeve 105, and the second sliding sleeve 202 is moved by the threaded engagement between the second screw 204 and the second threaded sleeve 205. This allows the first and second threaded sleeves 105 to be automatically and securely fixed after adjustment, which helps to improve the structural stability of the device after unfolding. At the same time, the flexible movement and automatic holding of the first and second threaded sleeves 105 and 205 allow for flexible control of the unfolding angle of the numerous first side support rods 101 and second side support rods 201. This enables the device to be flexibly adapted to the installation of solar panels of different sizes, thus improving the applicability and flexibility of the device to a certain extent.

[0044] In the specific implementation process, such as Figure 1 and Figure 7As shown, the connector 3 includes a bearing 301 rotatably connected to the top of the first side support rod 101, and a first torsion spring 302 is installed at the rotatable connection between the bearing 301 and the top of the first side support rod 101. A C-shaped clamp 303 is installed on the outside of the bearing 301. The base 4 is rotatably connected to the bottom of the second side support rod 201, and a second torsion spring 401 is installed at the rotatable connection between the base 4 and the bottom of the second side support rod 201. In actual use, by rotatably installing the bearing 301 at the top of the first side support rod 101 and rotatably installing the base 4 at the bottom of the second side support rod 201, the C-shaped clamp 303 can stably fit and connect with the bottom of the solar panel at different unfolding angles of the first side support rod 101 and the first sliding sleeve 102, while the base 4 can stably fit and connect with the ground, ensuring the actual operation of the device. To ensure stability during use, since both the bearing seat 301 and the base 4 rotate, this application addresses the issue of arbitrary rotation and collision between the bearing seat 301 and the base 4 during retraction and storage. This is achieved by installing a first torsion spring 302 for elastic support at the rotational connection between the bearing seat 301 and the top of the first side support rod 101, and a second torsion spring 401 for elastic support at the rotational connection between the base 4 and the bottom of the second side support rod 201. This allows the bearing seat 301 to rotate and adhere to the end wall of the upper end of the first side support rod 101 away from the first main rod 1, ensuring that the connector 3 always faces outwards when not subjected to external force. Similarly, the base 4 can rotate and adhere to the end wall of the bottom of the second side support rod 201 away from the second main rod 2, also always facing outwards when not subjected to external force. This design helps ensure the stability of the device during retraction and storage.

[0045] In the specific implementation process, such as Figure 3 and Figure 7 As shown, the C-shaped clamp 303 is rotatably connected to the bearing seat 301. The rotation axis of the C-shaped clamp 303 is perpendicular to the rotation axis of the bearing seat 301. In actual use, by rotatably mounting the C-shaped clamp 303 on the bearing seat 301 and setting the rotation axis of the C-shaped clamp 303 perpendicular to the rotation axis of the bearing seat 301, the operator can adjust the deflection angle of the C-shaped clamp 303 by rotation when fixing the bottom of the solar panel to the bottom of the solar panel. This improves the flexibility of installing the C-shaped clamp 303 and the bottom of the solar panel.

[0046] In the specific implementation process, such as Figure 2 , Figure 3 and Figure 10As shown, when the first main rod 1 and the second main rod 2 are vertically aligned, there is a 45° angle between the rotation axis of the first side support rod 101 and the rotation axis of the first hinge platform 5 on the horizontal plane. In actual use, when the first main rod 1 is not tilted relative to the second main rod 2, the first main rod 1 and the second main rod 2 are on the same vertical line. In this state, there is a 45° angle between the rotation axis of the first side support rod 101 and the rotation axis of the first hinge platform 5 on the horizontal plane. This makes the central axis of the rotation axis of the first hinge platform 5 point to the middle position between the rotation axes of two adjacent first side support rods 101. When aligned, the four first side support rods 101 unfold into an X-shaped structure instead of a cross-shaped structure. This allows the upper ends of the four first side support rods 101 to be connected to the four corners of the bottom of the solar panel through the corresponding connectors 3, instead of the middle position of the four sides of the bottom of the solar panel. By connecting the tops of the four first side support rods 101 to the four corners of the bottom of the solar panel, the stability of the solar panel when supported by the device can be effectively improved.

[0047] In the specific implementation process, such as Figure 2 , Figure 5 and Figure 6 As shown, a first bevel tooth 6 is fixedly installed at the bottom end of the first screw 104 and is disposed in the first hinge platform 5. A second bevel tooth 601 is fixedly installed at the top end of the first screw 104 and is disposed in the second hinge platform 501. A third bevel tooth 602 is meshed between the first bevel tooth 6 and the second bevel tooth 601. The third bevel tooth 602 is rotatably installed between the first hinge platform 5 and the second hinge platform 501. The third bevel tooth 602 is coaxially arranged with the rotation axis of the first hinge platform 5 and the second hinge platform 501. A shaft 603 is fixedly installed in the first hinge platform 5 and is coaxially arranged with its rotation axis. A shaft sleeve 604 is movably sleeved on the outside of the shaft 603. A straight spring 605 is installed in the shaft sleeve 604 and elastically supported between the shaft 603 and the shaft sleeve 604. The third bevel tooth 602 is rotatably installed at the end of the shaft sleeve 604.

[0048] In actual use, the device utilizes the meshing transmission of the first bevel gear 6, the second bevel gear 601, and the third bevel gear 602 to allow the upper first screw 104 and the lower second screw 204 to rotate synchronously. Taking the rotation of the second screw 204 as an example, the rotation of the second screw 204 will drive the rotation of the second bevel gear 601 fixed at its top. Through the meshing of the second bevel gear 601 and the third bevel gear 602, as well as the meshing of the first bevel gear 601 and the third bevel gear 602, the first screw 104 will be driven to rotate by the third bevel gear 602. Through the threaded engagement of the first screw 104 and the first screw sleeve 105, and the second screw 204... 04. The threaded engagement of the second threaded sleeve 205 enables the unfolding operation of the upper and lower parts of the device. Under the meshing transmission of the first bevel tooth 6, the second bevel tooth 601, and the third bevel tooth 602, the unfolding of the upper and lower parts of the device can be carried out synchronously, which is beneficial to improving the ease of operation in actual use. By setting the third bevel tooth 602 to be on the same straight line as the rotation axis of the first hinge platform 5 and the second hinge platform 501, the rotation adjustment of the first hinge platform 5 and the second hinge platform 501 will not affect the meshing transmission of the first bevel tooth 6, the second bevel tooth 601, and the third bevel tooth 602, which is beneficial to ensuring the stability of the device in actual use.

[0049] In actual use, the device utilizes the elastic support of the straight spring 605 to keep the cylinder 604 away from the shaft 603, allowing the third bevel tooth 602 to closely engage with the first bevel tooth 6 and the second bevel tooth 601. This ensures the stability of the synchronous rotation between the first screw 104 and the second screw 204. When the driven screw 104 or the second screw 204 is restricted in rotation, the driven screw 104 or the second screw 204 can still maintain its rotation under sufficient rotational force. This allows for adjustments to the deflection angles of the first side support rod 101 and the second side support rod 201 under different conditions, even when the first screw 104 and the second screw 204 are connected, thus improving the flexibility of the device in actual use.

[0050] In the specific implementation process, such as Figure 2 and Figure 4As shown, a first servo motor 504 is fixedly installed on the outer end wall of the second hinge platform 501, and the drive shaft of the first servo motor 504 is connected to the worm gear 503. A second servo motor 606 is fixedly installed at the bottom of the second main rod 2, and the drive shaft of the second servo motor 606 is connected to the second screw 204. In actual use, the operator can use the first servo motor 504 to provide power for the deflection adjustment of the first main rod 1 and the second main rod 2. After the first servo motor 504 is powered on, it transmits the rotational power to the worm gear 503, and with the help of the worm gear 503 and... The meshing of the worm gear 502 drives it to rotate, which in turn drives the first hinge platform 5 to rotate relative to the second hinge platform 501. By adjusting the deflection angle between the first main rod 1 and the second main rod 2, the tilt angle of the solar panel installed on the device can be adjusted. When the device is unfolded to support the solar panel for photovoltaic power generation, the external control device will control the first servo motor 504 to start and adjust the tilt angle of the solar panel in real time according to the sun's position, so that the solar panel can always face the sun after tilt adjustment, which is conducive to maximizing the efficiency of photovoltaic power generation.

[0051] When adjusting the device's deployment and retraction, the operator can supply power to the second servo motor 606. Once powered on, the second servo motor 606 drives the second screw 204, which is connected to its drive shaft, to rotate. The threaded engagement of the second screw 204 and the second threaded sleeve 205 provides power for the deployment of the lower second side support rod 201. Subsequently, through the meshing of the second bevel gear 601, the third bevel gear 602, and the first bevel gear 6, the first screw 104 is driven to rotate. The threaded engagement of the first screw 104 and the first threaded sleeve 105 provides power for the deployment of the upper first side support rod 101. The operator can first deploy the first side support rod 101 to a suitable tilt angle for the solar panel. Then, the operator... Connector 3 fixes the top of the first side support rod 101 to the bottom of the solar panel. After the connection between the first side support rod 101 and the solar panel is completed, the first side support rod 101 can no longer be rotated or adjusted. This makes it impossible for the first screw 104 to rotate within the first main rod 1. At this time, the operator can continue to drive the second screw 204 to rotate through the second servo motor 606. With the help of the squeezing action of the second bevel tooth 601 and the third bevel tooth 602, the second screw 204 can continue to be driven to rotate, thereby continuing to adjust the tilt angle of the second side support rod 201. In this mode, the operator needs to complete the connection between the first side support rod 101 and the solar panel first, and then install and fix the second side support rod 201 to the ground. The operation is flexible and convenient.

[0052] In the specific implementation process, such as Figure 2 , Figure 7 and Figure 10As shown, a support platform 7 is slidably installed on the top of the first main rod 1, and a bolt 701 is threaded onto the outer end wall of the support platform 7. The bolt 701 points vertically toward the outer end wall of the first main rod 1. In actual use, after the first side support rod 101 is unfolded and connected to the four corners of the bottom of the solar panel through the connector 3, the top of the support platform 7 can be supported at the middle position of the bottom of the solar panel by sliding adjustment of the support platform 7. The position of the support platform 7 is locked by the screw connection of the bolt 701. Then, the staff can fix the top of the support platform 7 to the middle position of the bottom of the solar panel, so that the device can achieve five-point support for the four corners and the middle position of the bottom of the solar panel. This is conducive to further improving the structural stability of the device when supporting the solar panel for photovoltaic power generation and is suitable for stable use in outdoor windy weather.
