As the concept of clean energy and sustainable development of resources becomes increasingly popular, safe and environmentally friendly photovoltaic power generation technology has been widely promoted and used in existing technologies. Usually, outdoor photovoltaic power generation equipment consists of solar panels and supporting devices.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Embodiment: This embodiment provides a photovoltaic power generation device with an easy-to-install structure, see Figure 1Specifically, it comprises a first main rod 1, four vertically arranged first side support rods 101 are hinged around the lower position of the outer end wall of the first main rod 1, a first sliding sleeve 102 is provided on the outer sliding sleeve of the first main rod 1, a first hinge rod 103 is hinged between the inner middle position of the first side support rod 101 and the first sliding sleeve 102, a second main rod 2 is arranged on the same straight line as the first main rod 1 below, and four vertically arranged second side support rods 201 are hinged around the upper position of the outer end wall of the second main rod 2, and a second sliding sleeve 203 is provided on the outer sliding sleeve of the second main rod 2 02, a second hinged rod 203 is hinged between the inner middle position of the second side support rod 201 and the second sliding sleeve 202, a connecting piece 3 is installed at the top end of the first side support rod 101, a base 4 is installed at the bottom end of the second side support rod 201, a first hinged platform 5 is fixedly installed at the bottom end of the first main rod 1, a second hinged platform 501 rotatably connected to the first hinged platform 5 is fixedly installed at the top end of the first main rod 1, a worm gear 502 coaxially arranged with its rotation axis is fixedly installed in the first hinged platform 5, and a worm 503 meshing with the worm gear 502 is rotatably installed in the second hinged platform 501.

[0038] The device is in a retracted state during transportation and storage, with numerous surrounding first side support rods 101 clinging to the outer end wall of the first main rod 1, and numerous surrounding second side support rods 201 clinging to the outer end wall of the second main rod 2, so that the device as a whole presents a sturdy column-shaped structure. The overall volume is small in the retracted state, and the space occupied is greatly reduced. After retracting, the structure is standardized and square, which is easy to stack, and can effectively ensure the convenience of the device during transportation and storage.

[0039] When the device is actually used, it needs to be unfolded. At this time, the staff can first unfold the second side support rod 201 at the bottom. In the initial state, the second sliding sleeve 202 is at the upper position outside the second main rod 2. Then the staff controls the second sliding sleeve 202 to move downward along the second main rod 2. The downward movement of the second sliding sleeve 202 drives the second hinged rod 203 to move downward away from one end of the second side support rod 201. Under the rotation support of the second hinged rod 203, many second side support rods 201 are supported and rotated, and the lower end of the second side support rod 201 is unfolded outward away from the second main rod 2, finally making the second main rod 2 and the second side support rod 201 unfold outward. The two side support rods 201 and the second sliding sleeve 202 cooperate with the second hinged rod 203 to form an unfolded umbrella-shaped structure. The staff can fix the lower end of the second side support rod 201 to the ground through the base 4 to install the device. When the base 4 is fixedly connected to the ground, the second main rod 2 and the second side support rod 201 cooperate with the second hinged rod 203 to form a triangular support structure. The two adjacent second side support rods 201 cooperate with the ground to 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 for the device.

[0040] Subsequently, the staff can unfold the first side support rod 101 at the top. In the initial state, the first sliding sleeve 102 is at the lower outer side of 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 first hinged rod 103 to move upward away from the end of the first side support rod 101. Under the rotation support of the first hinged rod 103, many first side support rods 101 are supported and rotated, and the upper ends of the first side support rods 101 are unfolded outward away from the first main rod 1, and finally the first main rod 1, the first side support rod 101, the first sliding sleeve 102 cooperate with the first hinged rod 103 to form an inverted unfolded umbrella-shaped structure. After unfolding, the four first side support rods 1 The upper ends of 01 are on the same horizontal plane, and the staff can fix the solar panel to the top ends of the four first side support rods 101 through the connecting piece 3 to complete the connection between the solar panel and the device. At this time, the first main rod 1 and the first side support rod 101 cooperate with the first hinge rod 103 to form a triangular support structure, and the two adjacent first side support rods 101 cooperate with the solar panel to also form a triangular support structure. Similarly, with the support stability of the triangular structure, the many first side support rods 101 after unfolding can provide stable supporting force for the solar panel installed above. After the device is unfolded, many mutually coordinated triangular structures are formed inside, which can effectively improve the stability of the solar panel when supported by the device.

[0041] During actual use, the device only needs to drive the corresponding first hinged rod 103 and second hinged rod 203 to move and support through the sliding of the first sliding sleeve 102 and the second sliding sleeve 202, so as to realize the deployment of the first side support rod 101 and the second side support rod 201 arranged around, and can be used for the installation of solar panels. The operation is convenient, and the convenience of solar panel installation can be effectively improved, so that the staff can easily and stably install the solar panel for photovoltaic power generation. When the device is used to support the solar panel for photovoltaic power generation, the staff can adjust the first main rod 103 and the second hinged rod 201 by rotating between the first hinged platform 5 and the second hinged platform 501. 1 and the inclination angle of the second main rod 2, and then support the inclination angle of the solar panel supported above. In this process, the staff drives the worm 503 to rotate, and drives the worm wheel 502 to rotate by virtue of the meshing between the worm 503 and the worm wheel 502, and drives the first articulated platform 5 to rotate relative to the second articulated platform 501 to complete the angle adjustment operation. During the adjustment process, by virtue of the self-locking property of the meshing transmission between the worm 503 and the worm wheel 502, the solar panel is automatically fixed and stabilized after the inclination angle is adjusted. Through rotation adjustment, the top of the solar panel can always face the sun, which is conducive to ensuring the stability and efficiency of photovoltaic power generation.

[0042] In the specific implementation process, Figure 2 and Figure 4 - Figure 6As shown, a through groove is provided on the outer end wall of the first main rod 1 and the second main rod 2, a vertically arranged first screw rod 104 is rotatably installed in the first main rod 1, a first screw sleeve 105 threadedly screwed to the first screw rod 104 is slidably installed in the first main rod 1, and the first screw sleeve 105 is fixedly connected to the first sleeve 102 via the through groove, a vertically arranged second screw rod 204 is rotatably installed in the second main rod 2, a second screw sleeve 205 threadedly screwed to the second screw rod 204 is slidably installed in the first main rod 1, and the second screw sleeve 205 is fixedly connected to the second sleeve 202 via the through groove.

[0043] During the actual use of the device, when controlling the movement of the first sleeve 102, the staff can drive the first screw 104 to rotate, and with the help of the threaded connection between the first screw 104 and the first screw sleeve 105, the first screw sleeve 105 can be driven to move in the first main rod 1 during the rotation of the first screw 104, and with the help of the connection between the first screw sleeve 105 and the first sleeve 102 through the through groove, the first sleeve 102 is driven to move, so as to realize the deployment control of the plurality of first side support rods 101 outside the first main rod 1. Similarly, when controlling the movement of the second sleeve 202, the staff can drive the second screw 204 to rotate, and with the help of the threaded connection between the second screw 204 and the second screw sleeve 205, the second screw sleeve 205 can be driven to move in the second main rod 2 during the rotation of the second screw 204, and with the help of the connection between the second screw sleeve 205 and the second sleeve 202 By connecting with the through groove, the second sleeve 202 is driven to move, so as to realize the expansion control of the plurality of second side support rods 201 outside the second main rod 2, and the movement control of the first sleeve 102 is realized by the threaded engagement between the first screw 104 and the first screw sleeve 105, and the movement control of the second sleeve 202 is realized by the threaded engagement between the second screw 204 and the second screw sleeve 205, so that the first screw sleeve 105 and the second screw sleeve 205 can be automatically fixed and stabilized after movement and adjustment, which is beneficial to improve the structural stability of the device after expansion, and at the same time, with the help of the flexible movement and automatic retention of the first screw sleeve 105 and the second screw sleeve 205, the expansion angles of the plurality of first side support rods 101 and the second side support rods 201 can be flexibly controlled, so that the device can be flexibly adapted to the installation of solar panels of different sizes, which improves the applicability flexibility of the device to a certain extent.

[0044] In the specific implementation process, Figure 1 and Figure 7As shown, the connecting member 3 includes an axle seat 301 rotatably connected to the top end of the first side support rod 101, and a first torsion spring 302 is installed at the rotation connection between the axle seat 301 and the top end of the first side support rod 101, a C-shaped clamp 303 is installed on the outer side of the axle seat 301, and the base 4 is rotatably connected to the bottom end of the second side support rod 201, and a second torsion spring 401 is installed at the rotation connection between the base 4 and the bottom end of the second side support rod 201. During the actual use of the device, the axle seat 301 is rotatably installed on the top end of the first side support rod 101, and the base 4 is rotatably installed on the bottom end of the second side support rod 201. With the help of rotation adjustment, at different expansion angles of the first side support rod 101 and the first sliding sleeve 102, the C-shaped clamp 303 can be stably fitted and connected to the bottom of the solar panel, and the base 4 can be stably fitted and connected to the ground, thereby ensuring that the device is actually To ensure stability during use, since both the axle seat 301 and the base 4 will rotate, in order to avoid the axle seat 301 and the base 4 from rotating and colliding randomly when the device is folded and stored, in the present application, the first torsion spring 302 for elastic support is installed at the rotation connection between the axle seat 301 and the top of the first side support rod 101, and the second torsion spring 401 for elastic support is installed at the rotation connection between the base 4 and the bottom of the second side support rod 201, so that the axle seat 301 can be rotatably fitted on the end wall of the upper end of the first side support rod 101 away from the first main rod 1. In the absence of external force, the connecting member 3 is always facing outward as a whole, and the base 4 can be rotatably fitted on the end wall of the lower end of the second side support rod 201 away from the second main rod 2. In the absence of external force, the base 4 is also always facing outward, which is beneficial to ensure the stability of the device when it is folded and stored.

[0045] In the specific implementation process, Figure 3 and Figure 7 As shown, the C-shaped clamp 303 is rotatably connected to the shaft seat 301, and the rotation axis of the C-shaped clamp 303 is perpendicular to the rotation axis of the shaft seat 301. During the actual use of the device, the C-shaped clamp 303 is rotatably installed on the shaft seat 301, and the rotation axis of the C-shaped clamp 303 is perpendicular to the rotation axis of the shaft seat 301. This allows the staff to adjust the deflection angle of the C-shaped clamp 303 by rotating when fixing the bottom of the solar panel to the C-shaped clamp 303, which is beneficial to improving the flexibility of the C-shaped clamp 303 when it is installed on the bottom of the solar panel.

[0046] In the specific implementation process, Figure 2 , Figure 3 and Fig.10As shown, when the first main rod 1 and the second main rod 2 are vertically in the same straight line, there is an angle of 45° between the rotation axis of the first side support rod 101 and the rotation axis of the first articulated platform 5 in the horizontal plane. During the actual use of the device, 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 in the same vertical line. In this state, there is an angle of 45° between the rotation axis of the first side support rod 101 and the rotation axis of the first articulated platform 5 in the horizontal plane, which makes the central axis of the rotation axis of the first articulated platform 5 point to the middle position between the rotation axes of two adjacent first side support rods 101. When aligned, the upper four first side support rods 101 present an X-shaped structure instead of a cross structure after unfolding, which makes the upper ends of the four first side support rods 101 can be connected to the four corners of the bottom of the solar panel through the corresponding connecting members 3, instead of being connected to the middle position of the four sides of the bottom of the solar panel. With the connection between the top ends of the four first side support rods 101 and 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, Figure 2 , Figure 5 and Figure 6 As shown, the bottom end of the first screw rod 104 is fixedly installed with a first bevel tooth 6 arranged in the first hinge platform 5, and the top end of the first screw rod 104 is fixedly installed with a second bevel tooth 601 arranged in the second hinge platform 501. The first bevel tooth 6 and the second bevel tooth 601 are meshed and connected with a third bevel tooth 602. 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 rod 603 coaxially arranged with its rotation axis is fixedly installed in the first hinge platform 5, and a shaft cylinder 604 is movably sleeved on the outer side of the shaft rod 603. A straight spring 605 elastically supported between the shaft rod 603 and the shaft cylinder 604 is installed in the shaft cylinder 604, and the third bevel tooth 602 is rotatably installed at the end of the shaft cylinder 604.

[0048] In actual use of the device, the first screw 104 at the top and the second screw 204 at the bottom can rotate synchronously by means of the meshing transmission of the first bevel gear 6, the second bevel gear 601 and the third bevel gear 602. For example, when a staff member drives the second screw 204 to rotate, the second bevel gear 601 fixed at the top thereof will be driven to rotate during the rotation of the second screw 204. By means of the meshing of the second bevel gear 601 and the third bevel gear 602, and the meshing of the first bevel gear 6 and the third bevel gear 602, the first screw 104 will be driven to rotate by the third bevel gear 602. By means of the threaded meshing of the first screw 104 and the first screw sleeve 105, and the meshing of the second screw 2 04 and the second screw sleeve 205 are threadedly engaged to realize 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 operational convenience of the device during actual use. By arranging the third bevel tooth 602 to be on the same straight line as the rotation axis of the first articulated platform 5 and the second articulated platform 501, the rotation adjustment of the first articulated platform 5 and the second articulated 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 during actual use.

[0049] When the device is actually used, with the elastic support of the straight spring 605, the shaft cylinder 604 keeps a tendency to move away from the shaft rod 603, so that the third bevel tooth 602 can be closely fitted with the first bevel tooth 6 and the second bevel tooth 601, thereby ensuring the stability of the synchronous rotation between the first screw rod 104 and the second screw rod 204. When the driven one of the first screw rod 104 or the second screw rod 204 is restricted in rotation, when sufficient rotational force is applied, the first screw rod 104 or the second screw rod 204 that is driven to actively rotate can still maintain a rotating state, so that when the first screw rod 104 and the second screw rod 204 are transmission-connected, the deflection and expansion angles of the first side support rod 101 and the second side support rod 201 can still be adjusted in different situations, which is conducive to improving the flexibility of the device during actual use.

[0050] In the specific implementation process, Figure 2 and Figure 4As shown, a first servo motor 504 is fixedly mounted on the outer end wall of the second hinged platform 501, and the driving shaft of the first servo motor 504 is transmission-connected to the worm 503, and a second servo motor 606 is fixedly mounted on the bottom of the second main rod 2, and the driving shaft of the second servo motor 606 is transmission-connected to the second screw 204. During the actual use of the device, the staff 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 and started, the rotational power is transmitted to the worm 503. With the help of the worm 503 and The meshing of the worm gear 502 drives the worm gear 502 to rotate, thereby driving the first articulated platform 5 to rotate relative to the second articulated platform 501. By adjusting the deflection angle between the first main rod 1 and the second main rod 2, the inclination angle of the solar panel installed above the device is adjusted. When the device is deployed 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 inclination angle of the solar panel in real time according to the position of the sun, so that the solar panel can always face the sunlight after the tilt adjustment, which is beneficial to maximizing the efficiency of photovoltaic power generation.

[0051] When the device is expanded and retracted, the staff can supply power to the second servo motor 606. After the second servo motor 606 is powered on and started, it will drive the second screw 204 connected to its drive shaft to rotate, and with the help of the threaded engagement of the second screw 204 and the second screw sleeve 205, power support is provided for the expansion of the second side support rod 201 below. Subsequently, the first screw 104 is driven to rotate through the meshing transmission of the second bevel gear 601, the third bevel gear 602 and the first bevel gear 6, and with the help of the threaded engagement of the first screw 104 and the first screw sleeve 105, power support is provided for the expansion of the first side support rod 101 above. The staff can first expand the first side support rod 101 to a suitable inclination angle of the solar panel, and then the staff can expand the first side support rod 101 to a suitable inclination angle of the solar panel. The connecting piece 3 fixedly connects the top of the first side support rod 101 with 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 and adjusted, which makes the first screw rod 104 unable to rotate in the first main rod 1. At this time, the staff can continue to drive the second screw rod 204 to rotate through the second servo motor 606. With the help of the idling of the second bevel gear 601 and the third bevel gear 602 under the extrusion action, the second screw rod 204 can be driven to rotate continuously, so as to continue to adjust the inclination angle of the second side support rod 201. In this mode, the staff 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, Figure 2 , Figure 7 and Fig.10As shown, a support platform 7 is slidably installed on the top of the first main rod 1, and a bolt 701 is threadedly screwed on the outer end wall of the support platform 7, and the bolt 701 points vertically to the outer end wall of the first main rod 1. During actual use of the device, after the first side support rod 101 is unfolded and connected to the four corners of the bottom of the solar panel through the connecting piece 3, the support platform 7 can be slidably adjusted so that the top of the support platform 7 is supported in the middle position of the bottom of the solar panel. The position of the support platform 7 is locked by the spiral connection of the bolt 701. Subsequently, 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, which is beneficial to further improve the structural stability of the device when supporting the solar panel for photovoltaic power generation, and is suitable for stable use outdoors in windy weather.

[0053] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
