Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module installation devices, and particularly relates to a balcony photovoltaic installation device and a photovoltaic system. Background Art

[0002] Balcony photovoltaics is a small solar power generation system installed on building balconies, which converts solar energy into electrical energy for household or commercial scenarios through photovoltaic modules. Due to its ability to effectively utilize the building facade space and reduce the user's electricity cost, balcony photovoltaic systems have gradually become an important development direction of distributed photovoltaics. However, the installation of balcony photovoltaic modules needs to adapt to complex and diverse building structures and at the same time meet safety requirements such as wind pressure resistance, which puts higher demands on the adaptability, stability and adjustability of the installation system.

[0003] In the prior art, balcony photovoltaic modules are usually fixed by upper U-shaped hook bolts in cooperation with lower horizontally installed clamping plates. Specifically, the upper part of the balcony photovoltaic module is first fastened to the U-shaped hook bolts, and then the U-shaped hook is used to hang and engage with the top of the railing handrail to bear the load; the lower part of the balcony photovoltaic module relies on the horizontally installed clamping plate to be friction-fixed to the bottom cross bar of the railing. However, during the actual installation of balcony photovoltaic modules, due to the fixed opening size of the U-shaped hook, it is difficult to adapt to different widths or special-shaped railing handrails, resulting in a large installation gap and insufficient binding force between the U-shaped hook and the railing handrail; in addition, when the entire balcony photovoltaic product generates an upward displacement due to negative wind pressure, the connection point at the bottom of the module plays a constraint role before the connection point at the top, and the lower clamping plate only relies on friction to prevent slipping and cannot effectively resist the upward displacement caused by negative wind pressure. Summary of the Invention

[0004] In view of this, the present invention provides a balcony photovoltaic installation device and a photovoltaic system to solve the problems of insufficient binding force of the balcony photovoltaic module installation device in the prior art and the inability to effectively resist the upward displacement caused by negative wind pressure.

[0005] In a first aspect, the present invention provides a balcony photovoltaic installation device, including: A first installation component, which includes a first hook and a first installation member fixedly connected. A first abutting member is installed on the first hook, and the first abutting member penetrates through one side wall of the first hook and is arranged towards the other inner side wall of the first hook; A second installation component, which includes a second hook and a second installation member. A second abutting member is installed on the second hook, and the second abutting member penetrates through one side wall of the second hook and is arranged towards the other inner side wall of the second hook. A first adjusting member is arranged on the second hook, and a second adjusting member is arranged on the second installation member. The first adjusting member and the second adjusting member extend in parallel, and the first adjusting member and the second adjusting member are adapted to be detachably connected by a connecting member; The first hook and the second hook are adapted to be installed in cooperation with the balcony railing, and the photovoltaic bracket is adapted to be installed and fixed through the first mounting member and the second mounting member.

[0006] The balcony photovoltaic installation device is used to realize the stable installation of the photovoltaic module on the balcony railing. When installing on the balcony railing, one of the first installation component or the second installation component is installed at the bottom of the balcony railing, and the other is installed at the top of the balcony railing. The first hook and the second hook are respectively hung and installed on the upper and lower sides of the balcony railing. By adjusting the extension amount of the first abutting member on the first hook, the first hook can be adapted to railing handrails of different thicknesses or shapes to form clamping fixation; by adjusting the extension amount of the second abutting member on the second hook, the second hook can also be adapted to railing handrails of different thicknesses or shapes to form clamping fixation. At the same time, by setting the first adjusting member and the second adjusting member, the second hook and the second mounting member are detachably connected by connecting members such as bolts. By adjusting the installation position of the connecting member, the relative position between the second hook and the second mounting member can be changed, and further the distance between the second installation component and the first installation component can be changed, so as to meet the requirements of different railing heights. The photovoltaic bracket is fixed by the first mounting member and the second mounting member. The first hook and the second hook are used to symmetrically clamp the railing in a double-hook manner to form a hoop-type mechanical constraint. At the same time, the up-and-down adjustment function ensures that the force on the component is evenly distributed. The photovoltaic panel is installed on the photovoltaic bracket to form a photovoltaic module. When the photovoltaic module is installed on the balcony railing by the balcony photovoltaic installation device, the first installation component and the second installation component can be adjusted according to the thickness and height of the balcony railing, so that the photovoltaic bracket in the photovoltaic module can be stably installed on the balcony railing of any shape, thickness and height through the cooperation of the first installation component and the second installation component. At the same time, the cooperation of the first hook and the second hook with the balcony railing can ensure a stable binding force between the balcony photovoltaic installation device and the balcony railing, thereby effectively resisting the upward displacement of the photovoltaic module caused by negative wind pressure and improving the stability of the photovoltaic module under external forces.

[0007] In an alternative embodiment, the first hook is an "n"-shaped hook, and the first mounting member is fixedly connected to the outer side wall of the first hook.

[0008] The "n"-shaped hook cooperates with the top or bottom or side of the balcony railing through the opening to ensure that the contact surface between the hook and the railing fits tightly, reducing the installation gap. The first mounting member is directly fixed to the outer side wall of the first hook to provide rigid support for the photovoltaic module.

[0009] In an alternative embodiment, the first abutting member and the first mounting member are respectively installed on two opposite side walls of the first hook.

[0010] The first abutting member and the first mounting member are distributed on both sides of the first hook, forming a symmetric stress structure. The first abutting member clamps the inner side of the railing by adjusting the protruding amount, and the first mounting member fixes the photovoltaic module from the outside. The two sides cooperate to disperse the load, avoiding deformation or sliding of the first hook caused by concentrated stress on one side, and improving the stability and installation reliability of the cooperation and clamping between the first hook and the balcony railing.

[0011] In an alternative embodiment, the first mounting member includes a pair of mounting plates and at least one first mounting shaft, and the first mounting shaft is mounted between the pair of mounting plates.

[0012] The pair of mounting plates are fixedly parallel to the outer side wall of the hook. The first mounting shaft transversely penetrates the pair of mounting plates. The photovoltaic bracket is connected to the mounting plates through the first mounting shaft, allowing the module to finely adjust the angle around the shaft to adapt to the inclination requirements under different lighting conditions. At the same time, the rigid connection between the mounting plate and the shaft ensures the stability of the module under dynamic loads.

[0013] In an alternative embodiment, the second hook is a "J"-shaped hook, and the first adjusting member is provided on the longer side wall of the second hook.

[0014] The bent end of the "J"-shaped hook is clamped to the bottom or top or side of the railing. The first adjusting member is arranged along the long side wall of the second hook. By adjusting the position of the connecting member on the first adjusting member, the relative position between the second hook and the second mounting member is changed, so that the balcony photovoltaic installation device can adapt to balcony railings of different heights, avoiding installation failure caused by size deviation of the balcony railing.

[0015] In an alternative embodiment, the first adjusting member is a through slot extending along the length direction of the side wall of the second hook or a plurality of mounting holes arranged at intervals along the length direction of the side wall of the second hook; And / or, the second adjusting member is a through slot provided on the second mounting member or a plurality of mounting holes arranged at intervals.

[0016] Both the through slot and the spaced mounting holes can provide multi-position connection points. The connecting member can slide along the slot or select different hole positions for installation and fixation, realizing stepless or stepped adjustment of the distance between the second hook and the second mounting member, enabling the balcony photovoltaic installation device to flexibly adjust the installation position according to the railing height and the height of the photovoltaic module, so as to adapt to photovoltaic modules of different sizes and railings of different heights. At the same time, it can avoid the existence of a suspended gap behind the photovoltaic module or the inability of the photovoltaic module to be installed into the balcony photovoltaic installation device caused by the mismatch between the railing height and the photovoltaic module height due to processing errors during the production process, ensuring the stability of the photovoltaic module after installation.

[0017] In an alternative embodiment, the second mounting member includes a "U"-shaped adapter block and a second mounting shaft, and the second mounting shaft is mounted in the groove of the "U"-shaped adapter block.

[0018] The second mounting axis set in the groove of the "U"-shaped adapter block cooperates with the photovoltaic bracket to fix the photovoltaic bracket and form a stable support for the photovoltaic bracket. After the photovoltaic bracket of the photovoltaic module is connected to the second mounting axis, it can be rotated around the second mounting axis by a certain angle, so that the inclination angle of the photovoltaic bracket can be fine-tuned according to the installation position. The "U"-shaped connection block can make part of the photovoltaic bracket built into the groove of the "U"-shaped adapter block after installation, increase the stability of the connection between the photovoltaic bracket and the second mounting component, and prevent the photovoltaic bracket from loosening, offsetting or falling off during long-term operation of the photovoltaic module.

[0019] In an optional embodiment, the first abutment member includes an abutment rod and an abutment pressure plate, the abutment rod is threadedly matched with the first hook, and the abutment pressure plate is installed at one end of the abutment rod facing the inner side of the first hook. When the abutment rod is rotated, the thread drives the abutment rod to move toward the inner side of the first hook, and the abutment pressure plate is pushed along with the abutment rod and presses the railing surface. The pressure plate can increase the contact area with the railing, disperse local pressure, and avoid scratches on the railing surface; the threaded match can achieve precise adjustment, which can ensure uniform distribution of clamping force, adapt to different railing thicknesses or shapes, and improve clamping reliability.

[0020] In an optional embodiment, an operating rotary block is installed at one end of the abutment rod away from the abutment pressing sheet. By providing the operating rotary block to provide a manual rotation fulcrum, the extension length of the abutment rod can be quickly adjusted without tools.

[0021] In a second aspect, the present invention further provides a photovoltaic system having the balcony photovoltaic installation device of the present invention. Because the photovoltaic system includes the balcony photovoltaic installation device, it has the same effect as the balcony photovoltaic installation device, which will not be described in detail here.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The following will be combined with Figures 1 to 3 , to describe the embodiments of the present invention.

[0029] According to an embodiment of the present invention, on the one hand, a balcony photovoltaic installation device is provided, which includes a first mounting assembly 1 and a second mounting assembly 2.

[0030] The first mounting assembly 1 includes a first hook 101 and a first mounting member 102 that are fixedly connected. A first abutting member 103 is mounted on the first hook 101. The first abutting member 103 penetrates through one side wall of the first hook 101 and is arranged toward the other inner side wall of the first hook 101. The second mounting assembly 2 includes a second hook 201 and a second mounting member 202. A second abutting member 203 is mounted on the second hook 201. The second abutting member 203 penetrates through one side wall of the second hook 201 and is arranged toward the other inner side wall of the second hook 201. A first adjusting member 204 is arranged on the second hook 201, and a second adjusting member 205 is arranged on the second mounting member 202. The first adjusting member 204 and the second adjusting member 205 extend in parallel. The first adjusting member 204 and the second adjusting member 205 are adapted to be detachably connected through a connecting member 206. The first hook 101 and the second hook 201 are adapted to be installed in cooperation with the balcony railing, and the photovoltaic bracket 3 is adapted to be installed and fixed through the first mounting member 102 and the second mounting member 202.

[0031] It should be noted that the first mounting component 1 and the second mounting component 2 are respectively installed in cooperation with the upper and lower sides of the photovoltaic bracket 3 in the photovoltaic module. The first hook 101 on the first mounting component 1 and the second hook 201 on the second mounting component 2 are respectively hung on the upper and lower sides of the balcony railing. In this embodiment, the first hook 101 has an opening facing downwards and is hung on the upper side of the balcony railing, and the second hook 201 has an opening facing upwards and is hung on the lower side of the balcony railing. In some other embodiments, the first hook 101 can also have an opening facing upwards and be hung on the lower side of the balcony railing, and the second hook 201 has an opening facing downwards and is hung on the upper side of the balcony railing; or the first hook 101 and the second hook 201 are respectively hung on the left and right sides of the balcony railing.

[0032] The balcony photovoltaic installation device realizes the stable installation of the photovoltaic module on the balcony railing through a double-hook structure. In practical applications, the first mounting component 1 is installed at the bottom of the balcony railing, and the second mounting component 2 is installed at the top of the balcony railing. The first hook 101 and the second hook 201 are respectively hung on the upper and lower sides of the balcony railing to form a stable support structure. By adjusting the extension amount of the first abutting member 103 on the first hook 101, the clamping force between the first hook 101 and the railing handrail can be flexibly adjusted, so as to adapt to railing handrails of different thicknesses or shapes and achieve stable clamping and fixing. Similarly, the second abutting member 203 on the second hook 201 can be adapted to the bottom structure of the railing of different specifications by adjusting the extension amount to ensure the full-surface fit of the balcony photovoltaic installation device and the railing. The second hook 201 and the second mounting member 202 in the second mounting component 2 are provided with a first adjusting member 204 and a second adjusting member 205. The second hook 201 and the second mounting member 202 can be detachably connected by cooperating with the first adjusting member 204 and the second adjusting member 205 through a connecting member 206 such as a bolt. By adjusting the installation position of the connecting member 206 on the first adjusting member 204 and the second adjusting member 205, the relative position of the second hook 201 and the second mounting member 202 can be changed, and further the distance between the second mounting member 202 and the first mounting member 102 can be flexibly adjusted to meet the railing height requirements of different heights. This design breaks through the limitation of the traditional installation method on the railing size, enabling the device to be widely applicable to the mainstream balcony railing structures in the market. The photovoltaic bracket 3 is fixedly installed on the balcony railing through the first mounting member 102 and the second mounting member 202. In practical applications, when negative wind pressure acts on the photovoltaic module, the double-hook structure formed by the first hook 101 and the second hook 201 evenly transmits the external force to the railing main body through the hoop-like binding force, avoiding the risk of component displacement or detachment caused by local stress concentration. The adjustment design of the first abutting member 103 and the second abutting member 203 enables the balcony photovoltaic installation device to be finely adjusted according to the actual size of the railing to ensure no shaking gap after installation.

[0033] In one embodiment, the first hook 101 is an "n"-shaped hook, and the first mounting member 102 is fixedly connected to the outer sidewall of the first hook 101. The opening structure of the "n"-shaped hook matches the top, bottom, or side profile of the balcony railing. The first hook 101 is clamped and fixed to the balcony railing by cooperating with a contact member, so that the contact surface between the first hook 101 and the railing fits closely, effectively reducing the installation gap. The first mounting member 102 is directly fixed to the outer sidewall of the first hook 101, providing a rigid support foundation for the photovoltaic module. The first mounting member 102 can be made of metal sheet or high-strength engineering plastic, and is connected to the outer sidewall of the first hook 101 by bolts to ensure the connection strength between the first hook 101 and the photovoltaic support 3. Or the first mounting member 102 and the first hook 101 are provided as an integrally formed structure to avoid structural deformation caused by lateral wind load or dynamic load, or the first mounting member 102 and the first hook 101 are fixed by welding. In some other embodiments, the first hook 101 can also be designed as an "Ω"-shaped or "C"-shaped to adapt to railings of different shapes while maintaining close contact with the railing.

[0034] In this embodiment, the first contact member 103 and the first mounting member 102 are respectively installed on two opposite sidewalls of the first hook 101. The first contact member 103 is installed through the sidewall of the first hook 101 by a threaded structure. By adjusting the protruding amount of the first contact member 103, the end of the first contact member 103 located inside the first hook 101 presses tightly against the surface of the balcony railing; the first mounting member 102 is fixed to the outer sidewall of the first hook 101 and is used to connect the photovoltaic support 3. The first contact member 103 and the first mounting member 102 form a symmetric force-bearing structure, and the load transmitted by the photovoltaic support 3 is dispersed through the bilateral cooperation. When the photovoltaic module is affected by wind pressure, the first contact member 103 bears the inward pressure, and the first mounting member 102 bears the outward tension. The two jointly limit the deformation or movement of the first hook 101, improving the clamping stability and installation reliability of the first hook 101 and the balcony railing. In another implementation manner, the first contact member 103 and the first mounting member 102 can be respectively installed at the top and bottom of the hook to meet different installation requirements.

[0035] In this embodiment, the first mounting member 102 includes a pair of parallel mounting plates 1021 and at least one first mounting shaft 1022. The first mounting shaft 1022 transversely penetrates the pair of mounting plates 1021 and is fixed between them. The mounting plates 1021 are fixed to the outer sidewall of the first hook 101 by welding or bolts. When installing the photovoltaic module, the first mounting shaft 1022 sequentially penetrates one of the mounting plates 1021, the photovoltaic support of the photovoltaic module, and the other mounting plate 1021. The two ends of the first mounting shaft 1022 are respectively embedded in the shaft holes of the mounting plates 1021 to fix the photovoltaic support 3 on the first mounting member 102. The photovoltaic support 3 is connected to the first mounting shaft 1022 through a shaft hole fit or a clamping structure. Anti-slip patterns or limit protrusions can also be provided on the surface of the first mounting shaft 1022 to prevent the photovoltaic support 3 from accidentally rotating after installation and positioning. At the same time, the first mounting shaft 1022 can also be a threaded shaft or a spline shaft to provide better connection strength.

[0036] In one embodiment, the second hook 201 is a "J"-shaped hook, and the first adjusting member 204 is provided on a longer sidewall of the second hook 201. The bent end of the "J"-shaped hook is clamped with the bottom, top or side structure of the balcony railing. The first adjusting member 204 extends along the length direction of the long sidewall of the second hook 201. By adjusting the installation position of the connecting member on the first adjusting member 204, the relative height between the second hook 201 and the second mounting member 202 can be changed, so as to adapt to balcony railings of different heights. By moving the position of the connecting member on the first adjusting member 204, balcony railings of different heights can be adapted, avoiding problems such as installation failure caused by railing height deviation or gaps between the second mounting assembly 2 and the railing after installation. In another implementation manner, the second hook 201 can be designed as an "L"-shaped or "S"-shaped hook to adapt to railings of different shapes and sizes, and can also adapt to special-shaped railings through bent ends with different arcs.

[0037] In one embodiment, the first adjusting member 204 may be a through notch extending along the length direction of the side wall of the second hook 201, or a plurality of mounting holes arranged at intervals along this direction. Similarly, the second adjusting member 205 may be a through notch provided on the second mounting member 202 or a plurality of mounting holes arranged at intervals. This design provides multiple connection points, enabling the connecting member to slide along the notch or select different hole positions for installation and fixation, thereby achieving stepless or stepped adjustment of the distance between the second hook 201 and the second mounting member 202. In this embodiment, the first adjusting member 204 is a through notch extending along the length direction of the side wall of the second hook 201, and the second adjusting member 205 is a plurality of mounting holes arranged at intervals on the second mounting member 202. The mounting holes arranged at intervals can provide a grading and positioning function, facilitating quick selection of a preset height. Scale marks can be provided on both sides of the through notch to assist in precise adjustment, and the spacing of the mounting holes can be designed according to the height of the standard railing. Through the combined design of the first adjusting member 204 and the second adjusting member 205, the balcony photovoltaic installation device can flexibly adapt to photovoltaic modules and balcony railings of different heights, eliminating problems such as component suspension gaps or installation interference caused by processing errors or installation environment differences. As an alternative implementation, the first adjusting member 204 and the second adjusting member 205 can also adopt a structure of a guide rail cooperating with a slider, or a magnetic adsorption type positioning mechanism, to achieve quick adjustment and locking.

[0038] In one embodiment, the second mounting member 202 includes a "U" - shaped adapter block and a second mounting shaft 2022. The second mounting shaft 2022 is installed in the groove of the "U" - shaped adapter block. After the photovoltaic support of the photovoltaic module is connected to the second mounting shaft 2022, it can rotate around the shaft by a certain angle, enabling the inclination angle of the photovoltaic support 3 to be finely adjusted according to the installation position. The design of the "U" - shaped adapter block makes a part of the area of the photovoltaic support 3 built - in the groove after installation, increasing the stability of the cooperation and connection between the photovoltaic module and the second mounting component 2, and preventing the photovoltaic support 3 from loosening, shifting or falling off during long - term operation. In another implementation, the second mounting member 202 can be designed as a "V" - shaped or "H" - shaped adapter block to adapt to different - shaped photovoltaic supports.

[0039] In one embodiment, the first abutment member 103 includes an abutment rod 1031 and an abutment pressing plate 1032. The abutment rod 1031 is threadedly matched with the first hook 101, and the abutment pressing plate 1032 is installed at one end of the abutment rod 1031 facing the inner side of the first hook 101. When the abutment rod 1031 is rotated, the thread drives the abutment rod 1031 to move toward the inner side of the first hook 101, driving the abutment pressing plate 1032 to press against the surface of the balcony railing. The contact surface of the abutment pressing plate 1032 is coated with rubber or engineering plastic, which not only increases the friction force to enhance the clamping effect, but also prevents hard materials from scratching the railing surface. The abutment pressing plate 1032 can be designed to be arc-shaped or wavy, which is further adapted to different railing cross-sectional shapes. The threaded matching structure realizes the precise displacement control of the abutment rod 1031, ensures that the clamping force is evenly distributed on the railing surface, and adapts to railings of different thicknesses. In some other embodiments, the first abutment member 103 may also adopt a hydraulic or spring-assisted adjustment mechanism to automatically adapt to different railing thicknesses.

[0040] Furthermore, an operating knob 1033 is installed at one end of the abutment rod 1031 which is away from the abutment pressure plate 1032. The operating knob 1033 is fixed to the end of the abutment rod 1031 by welding or threaded connection, and its surface is provided with anti-skid patterns or raised structures for easy manual operation. By rotating the operating knob 1033, the extension length of the abutment rod 1031 can be quickly adjusted without the aid of tools, thereby simplifying the installation process and improving the adjustment efficiency. The rigid connection between the operating knob 1033 and the abutment rod 1031 ensures the stable transmission of force during the adjustment process, and avoids the problem of thread jamming or clamping failure caused by improper operation. In another embodiment, the first abutment member 103 can be designed as a wedge block or an elastic claw to adapt to railings of different shapes and materials. In this embodiment, the second abutment member 203 has the same structure and working method as the first abutment member 103.

[0041] According to an embodiment of the present invention, on the other hand, a photovoltaic system is provided, which has a balcony photovoltaic installation device of the present invention, and also includes a photovoltaic assembly, wherein the photovoltaic assembly includes a photovoltaic bracket 3 and a photovoltaic panel installed on the photovoltaic bracket 3, such as Figure 3 As shown, the photovoltaic bracket 3 is fixedly installed on the balcony railing 4 through the balcony photovoltaic installation device. The photovoltaic system is installed on the balcony railing 4 through the balcony photovoltaic installation device provided by the present invention, and can be flexibly adjusted according to the thickness, height and shape of the balcony railing 4 to ensure the stable installation of the photovoltaic module. The double hook structure effectively resists the upward displacement caused by negative wind pressure, while dispersing the load, avoiding local force concentration, and significantly improving the safety and structural stability of the photovoltaic system.
