[0010] Based on this, it is necessary to provide a photovoltaic panel hoisting device for the above problems.

[0011] A photovoltaic panel hoisting device is used to be installed on the top of a photovoltaic support to hoist a photovoltaic panel. A plurality of crossbars for supporting the photovoltaic panel are provided on the top of the photovoltaic support. The photovoltaic panel hoisting device includes:

[0012] A first support assembly, the first support assembly includes a first support rod and a first mounting seat connected to the bottom end of the first support rod, and the first mounting seat is used for detachably connecting to one of the crossbars;

[0013] The second support assembly, which includes a second support rod and a second mounting base connected to the bottom end of the second support rod, and the second mounting base is used for detachably connecting to another crossbar;

[0014] A fixing assembly, the top end of the first support rod is connected to the top end of the second support rod through the fixing assembly; and

[0015] A lifting assembly, which is arranged on the fixing assembly and is used for lifting the photovoltaic panel.

[0016] The above-mentioned photovoltaic panel lifting device can at least achieve the following beneficial effects:

[0017] First, modular design: Each component (such as the first support assembly, the second support assembly, the fixing assembly, and the lifting assembly) adopts a modular design, which is convenient for transportation, storage, and maintenance. The modular design also enables each part of the device to be independently replaced and repaired, reducing the maintenance cost.

[0018] Second, strong flexibility and adaptability: The device can be flexibly applied in different construction environments, especially suitable for the lifting operation of photovoltaic panels in complex terrains and narrow spaces, solving the problem that traditional equipment is difficult to work in these environments. The design of this application takes into account the diversity of the crossbars at the top of the photovoltaic support. The first mounting base and the second mounting base can adapt to crossbars of different sizes and spacings, with strong adaptability, and can be widely applied to different types and specifications of photovoltaic supports.

[0019] Third, convenient installation: By detachably connecting the first mounting base and the second mounting base to the crossbars of the photovoltaic support respectively, the installation and disassembly process of the device is simple and fast, without the need for complex tools and operations, greatly reducing the labor intensity and time cost of the installation personnel, and also reducing the technical requirements and training costs for the operators, enabling the device to be quickly put into use and improving the construction efficiency.

[0020] Fourth, stable structure: The first support assembly and the second support assembly are connected through the fixing assembly to form a stable overall structure, ensuring the stability and safety of the device when lifting the photovoltaic panel, reducing the possible shaking and tilting during the operation, and enhancing the safety of the operation. The lifting assembly is arranged on the fixing assembly and can efficiently lift the photovoltaic panel. The design of the lifting assembly makes the lifting process of the photovoltaic panel more stable and precise, reducing the risk of damage to the photovoltaic panel during the lifting process and improving the operation efficiency.

[0021] In one embodiment, the first support assembly further includes a first adjusting member. The first adjusting member includes a first abutting end and a first adjusting end. The first adjusting member passes through the first mounting seat and is threadedly connected to the first mounting seat. The first mounting seat is hollow and is used for sleeving on the end of one of the cross bars. The first adjusting end is configured to be rotatable under an external force to drive the first abutting end to approach or move away from the cross bar within the first mounting seat. The first abutting end and the inner wall of the first mounting seat can clamp the cross bar within the first mounting seat from both sides. The threaded connection design of the first adjusting member makes the installation process simpler. The operator only needs to rotate the first adjusting end to easily adjust the position of the first abutting end, thereby achieving the clamping of the cross bar, without the need for additional tools and complex operating steps. Through the clamping action between the first abutting end and the inner wall of the first mounting seat, it can effectively prevent the first support assembly from sliding or falling off during use, further improving the safety of the hoisting device and ensuring the safety of the operating personnel. Moreover, the design of the first adjusting member enables the first support assembly to adapt to cross bars of different sizes, with strong adaptability. Regardless of slight differences in the diameter of the cross bar, the stable clamping can be achieved by adjusting the first adjusting member, expanding the application range of the device.

[0022] In one embodiment, the first adjusting member further includes a first operating rod. The first operating rod is disposed on the first adjusting end and is disposed at an angle to the first adjusting end. The first operating rod is used for being operated to drive the first adjusting member to rotate. The design of the first operating rod enables the operator to rotate the first adjusting member more easily. Since the first operating rod is disposed at an angle to the first adjusting end, the operator can achieve a larger rotation effect by applying a smaller force, reducing the operation difficulty and physical effort.

[0023] In one embodiment, the second support assembly further includes a second adjusting member, which includes a second abutting end and a second adjusting end. The second adjusting member passes through the second mounting seat and is threadedly connected to the second mounting seat. The second mounting seat is hollow and is used to sleeved on the end of the other cross bar. The second adjusting end is configured to be rotatable under an external force to drive the second abutting end to approach or move away from the cross bar within the second mounting seat. The second abutting end and the inner wall of the second mounting seat can clamp the cross bar within the second mounting seat from both sides. The threaded connection design of the second adjusting member makes the installation process more convenient. The operator only needs to rotate the second adjusting end to easily adjust the position of the second abutting end, thereby achieving the clamping of the cross bar, without additional tools and complex operation steps. Through the clamping action of the second abutting end and the inner wall of the second mounting seat, it can effectively prevent the second support assembly from sliding or falling off during use, further improving the safety of the hoisting device and ensuring the safety of the operators. Moreover, the design of the second adjusting member enables the second support assembly to adapt to cross bars of different sizes, with strong adaptability. Regardless of slight differences in the diameter of the cross bar, the stable clamping can be achieved by adjusting the second adjusting member, expanding the application range of the device.

[0024] In one embodiment, the second adjusting member further includes a second operating rod, which is disposed on the second adjusting end and is disposed at an angle to the second adjusting end. The second operating rod is used for operation to drive the second adjusting member to rotate. The design of the second operating rod enables the operator to rotate the second adjusting member more easily. Since the second operating rod is disposed at an angle to the second adjusting end, the operator can achieve a larger rotation effect by applying a smaller force, reducing the operation difficulty and physical exertion.

[0025] In one embodiment, the first support rod includes a first fastener, a first upper support tube, and a first lower support tube. The bottom end of the first lower support tube is connected to the first mounting seat.

Any one of the top end of the second lower support tube and the bottom end of the second upper support tube is coaxially sleeved on the other. The second upper support tube is detachably connected to the second lower support tube through the second fastener;

[0027] Wherein, the top end of the first upper support tube is detachably connected to the top end of the second upper support tube through the fixing assembly.

[0028] The modular design allows the first support rod and the second support rod to be split into smaller parts, which is convenient for transportation and storage, and reduces space occupation and transportation costs. In addition, the first fastener and the second fastener can be used to conveniently adjust the connection lengths between the first support upper tube and the first support lower tube, and the second support upper tube and the second support lower tube to meet different usage requirements.

Many specific details are set forth in the following description in order to fully understand the present utility model.

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0049] Please refer to Figure 1 and Figure 2 In some embodiments, the present application provides a photovoltaic panel 30 hoisting device 10, which can be installed on the top of a photovoltaic support 20 to hoist the photovoltaic panel 30. A plurality of crossbars 21 for supporting the photovoltaic panel 30 are provided on the top of the photovoltaic support 20. Among them, the photovoltaic panel 30 hoisting device 10 includes a first support assembly 100, a second support assembly 200, a fixing assembly 300, and a lifting assembly 400. The first support assembly 100 includes a first support rod 110 and a first mounting seat 120 connected to the bottom end of the first support rod 110; the second support assembly 200 includes a second support rod 210 and a second mounting seat 220 connected to the bottom end of the second support rod 210; as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the first mounting seat 120 is used for detachably connecting to one of the crossbars 21, and the second mounting seat 220 is used for detachably connecting to another crossbar 21. As Figure 7 and Figure 8 shown, the top end of the first support rod 110 is connected to the top end of the second support rod 210 through the fixing assembly 300, and the lifting assembly 400 is arranged on the fixing assembly 300 and is used for hoisting the photovoltaic panel 30.

[0050] The above-mentioned photovoltaic panel 30 hoisting device 10 can at least achieve the following beneficial effects:

[0051] First, modular design: Each component (such as the first support assembly 100, the second support assembly 200, the fixing assembly 300, and the lifting assembly 400) adopts a modular design, which is convenient for transportation, storage, and maintenance. The modular design also enables each part of the device to be independently replaced and repaired, reducing the maintenance cost.

[0052] Second, strong flexibility and adaptability: The device can be flexibly applied in different construction environments, especially suitable for hoisting operations of photovoltaic panels 30 in complex terrains and narrow spaces, solving the problem that traditional equipment is difficult to work in these environments. The design of the present application takes into account the diversity of the crossbars 21 on the top of the photovoltaic support 20. The first mounting seat 120 and the second mounting seat 220 can adapt to crossbars 21 of different sizes and spacings, with strong adaptability, and can be widely applied to different types and specifications of photovoltaic supports 20.

[0053] Thirdly, it is convenient to install: By detachably connecting the first mounting base 120 and the second mounting base 220 to the crossbar 21 of the photovoltaic bracket 20 respectively, the installation and disassembly process of the device is simple and fast, without the need for complex tools and operations, greatly reducing the labor intensity and time cost of installers, and also reducing the technical requirements and training costs for operators, enabling the device to be quickly put into use and improving the construction efficiency.

[0054] Fourthly, the structure is stable: The first support assembly 100 and the second support assembly 200 are connected by the fixing assembly 300 to form a stable overall structure, ensuring the stability and safety of the device when lifting the photovoltaic panel 30, reducing the possible shaking and tilting during the operation process, and enhancing the safety of the operation. The lifting assembly 400 is arranged on the fixing assembly 300 and can efficiently lift the photovoltaic panel 30. The design of the lifting assembly 400 makes the lifting process of the photovoltaic panel 30 more stable and precise, reducing the risk of damage to the photovoltaic panel 30 during the lifting process and improving the operation efficiency.

[0055] Specifically, as Figure 3 and Figure 4 shown, in some embodiments, the first support assembly 100 further includes a first adjusting member 130. The first adjusting member 130 includes a first abutting end 131 and a first adjusting end 132. The first adjusting member 130 passes through the first mounting base 120 and is threadedly connected to the first mounting base 120. The first mounting base 120 is hollow and is used to sleeved on the end of one of the crossbars 21. The first adjusting end 132 is configured to be able to rotate under the action of an external force to drive the first abutting end 131 to approach or move away from the crossbar 21 within the first mounting base 120. The first abutting end 131 and the inner wall of the first mounting base 120 can clamp the crossbar 21 within the first mounting base 120 from both sides. The threaded connection design of the first adjusting member 130 makes the installation process more convenient. The operator only needs to rotate the first adjusting end 132 to easily adjust the position of the first abutting end 131, thereby realizing the clamping of the crossbar 21, without the need for additional tools and complex operation steps. Through the clamping action of the first abutting end 131 and the inner wall of the first mounting base 120, it can effectively prevent the first support assembly 100 from sliding or falling off during use, further improving the safety of the lifting device 10 and ensuring the safety of the operators. Moreover, the design of the first adjusting member 130 enables the first support assembly 100 to adapt to crossbars 21 of different sizes, having strong adaptability. Regardless of slight differences in the diameter of the crossbar 21, the stable clamping can be achieved by adjusting the first adjusting member 130, expanding the application range of the device.

[0056] More specifically, as Figure 3 and Figure 4As shown, in some of the embodiments, the first adjusting member 130 further includes a first operating rod 133. The first operating rod 133 is disposed at the first adjusting end 132 and is arranged at an angle with the first adjusting end 132. The first operating rod 133 is for operation to drive the first adjusting member 130 to rotate. The design of the first operating rod 133 enables the operator to rotate the first adjusting member 130 more easily. Since the first operating rod 133 is arranged at an angle with the first adjusting end 132, the operator can achieve a larger rotation effect by applying a smaller force, reducing the operation difficulty and physical exertion.

[0057] Further, as Figure 5 and Figure 6 As shown, in some of the embodiments, the second support assembly 200 further includes a second adjusting member 230. The second adjusting member 230 includes a second abutting end 231 and a second adjusting end 232. The second adjusting member 230 is disposed through the second mounting seat 220 and is threadedly connected to the second mounting seat 220. The second mounting seat 220 is hollow and is for sleeving on the end of another cross bar 21. The second adjusting end 232 is configured to be rotatable under an external force to drive the second abutting end 231 to approach or move away from the cross bar 21 within the second mounting seat 220. The second abutting end 231 and the inner wall of the second mounting seat 220 can clamp the cross bar 21 within the second mounting seat 220 from both sides. The threaded connection design of the second adjusting member 230 makes the installation process more convenient. The operator can easily adjust the position of the second abutting end 231 by simply rotating the second adjusting end 232, thereby achieving the clamping of the cross bar 21 without additional tools and complex operation steps. Through the clamping action of the second abutting end 231 and the inner wall of the second mounting seat 220, it can effectively prevent the second support assembly 200 from sliding or falling off during use, further improving the safety of the hoisting device 10 and ensuring the safety of the operating personnel. Moreover, the design of the second adjusting member 230 enables the second support assembly 200 to adapt to cross bars 21 of different sizes, having strong adaptability. Regardless of slight differences in the diameter of the cross bar 21, stable clamping can be achieved by adjusting the second adjusting member 230, expanding the application range of the device.

[0058] Even further, as Figure 5 and Figure 6As shown, in some of the embodiments, the second adjusting member 230 further includes a second operating rod 233. The second operating rod 233 is disposed at the second adjusting end 232 and is arranged at an angle with the second adjusting end 232. The second operating rod 233 is for operation to drive the second adjusting member 230 to rotate. The design of the second operating rod 233 enables the operator to rotate the second adjusting member 230 more easily. Since the second operating rod 233 is arranged at an angle with the second adjusting end 232, the operator can achieve a larger rotation effect by applying a smaller force, reducing the operation difficulty and physical exertion.

[0059] Please refer to Figure 9 , Figure 10 and Figure 11 , in some of the embodiments, the first support rod 110 includes a first fastener 114, a first upper support tube 111 and a first lower support tube 112.

The bottom end of the second lower support tube 212 is connected to the second mounting seat 220. Either the top end of the second lower support tube 212 or the bottom end of the second upper support tube 211 is coaxially sleeved on the other. The second upper support tube 211 is detachably connected to the second lower support tube 212 through the second fastener 214;

[0061] Wherein, the top end of the first upper support tube 111 is detachably connected to the top end of the second upper support tube 211 through the fixing component 300.

[0062] The modular design enables the first support rod 110 and the second support rod 210 to be disassembled into smaller components, facilitating transportation and storage, and reducing the space occupation and transportation costs. In addition, through the first fastener 114 and the second fastener 214, the connection length between the first upper support tube 111 and the first lower support tube 112, and between the second upper support tube 211 and the second lower support tube 212 can be conveniently adjusted to meet different usage requirements.

[0063] Specifically, as Figure 9 , Figure 10 and Figure 11As shown, in some of the embodiments, at least one set of first upper limiting holes 1111 is provided on the outer circumferential surface of the first upper support tube 111, and at least one set of first lower limiting holes 1121 is provided on the outer circumferential surface of the first lower support tube 112. The top end of the first lower support tube 112 and the bottom end of the first upper support tube 111 are coaxially sleeved on one another, and when any one set of the first upper limiting holes 1111 is aligned with any one set of the first lower limiting holes 1121, the first fastener 114 can pass through the first upper limiting holes 1111 and the first lower limiting holes 1121 aligned with the first upper limiting holes 1111 to fix the first lower support tube 112 and the first upper support tube 111. The design of multiple sets of limiting holes enables the flexible adjustment of the length between the first upper support tube 111 and the first lower support tube 112 according to actual requirements to adapt to different usage scenarios and height requirements.

[0064] Specifically, as Figure 9 and Figure 10 shown, in some of the embodiments, at least one set of second upper limiting holes 2111 is provided on the outer circumferential surface of the second upper support tube 211, and at least one set of second lower limiting holes 2121 is provided on the outer circumferential surface of the second lower support tube 212. The top end of the second lower support tube 212 and the bottom end of the second upper support tube 211 are coaxially sleeved on one another, and when any one set of the second upper limiting holes 2111 is aligned with any one set of the second lower limiting holes 2121, the second fastener 214 can pass through the second upper limiting holes 2111 and the second lower limiting holes 2121 aligned with the second upper limiting holes 2111 to fix the second lower support tube 212 and the second upper support tube 211. The design of multiple sets of limiting holes enables the flexible adjustment of the length between the second upper support tube 211 and the second lower support tube 212 according to actual requirements to adapt to different usage scenarios and height requirements.

[0065] Please refer to Figure 4 and Figure 6 , in some of the embodiments, the first mounting seat 120 and the second mounting seat 220 are respectively detachably connected to two adjacent crossbars 21. The axis of the first lower support tube 112 is disposed at an acute angle with the top surface of the first mounting seat 120 at a first angle, and the axis of the second lower support tube 212 is disposed at an acute angle with the top surface of the second mounting seat 220 at a second angle. The second angle is the same as the second angle. The top ends of the first upper support tube 111 and the second upper support tube 211 converge with each other and are detachably connected through the fixing assembly 300. The same angle setting ensures the symmetry and balance of the two support rods when stressed, further improving the structural stability.

[0066] Please refer toFigure 8 In some embodiments, at the top end of the first support upper tube 111, there is provided a first fixing ring 113, and at the top end of the second support upper tube, there is provided a second fixing ring 213. The fixing assembly 300 includes a screw 310 and a nut 320. The screw 310 passes through the first fixing ring 113 and the second fixing ring 213 and is threadedly connected to the nut 320 to fix the first support rod 110 and the second support rod 210.
