Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a photovoltaic power generation system installed on a balcony. Background Art

[0002] There are many photovoltaic power generation systems installed on balcony guardrails in the prior art. For example, patent No. CN208461741U discloses a photovoltaic support installed on a railing, comprising two parallel inclined beams, the upper portion of which is provided with a fixing seat, the lower portion of which is provided with a support rod, the ends of which are provided with a connecting crossbar, and the connecting crossbar connects the two support rods. This utility model is used on various railings such as balconies or outdoors. It uses the railing as a base to be fixed on the railing, does not occupy internal space or the ground, has a simple and reliable structure, good versatility, and low cost, and can be widely used in home balconies, scenic area guardrails, etc. However, in actual use, because the above-mentioned technology connects the support rods through the lower connecting crossbar and installs the photovoltaic module on the railing at a certain angle, the installation angle of the photovoltaic module on the balcony is fixed, and the optimal lighting angle cannot be achieved by direct adjustment.

[0003] In order to achieve the inclination adjustment of photovoltaic modules, the existing technology provides many mature solutions. The patent with reference to announcement number 220754718U discloses a photovoltaic system with stepless inclination adjustment installed on a guardrail, which belongs to the field of photovoltaic power generation and solves the problem that the solar panels installed on the guardrail cannot be directly adjusted in angle on the guardrail. The technical solution to this problem is mainly that the adjustment component includes a lower fixing member, a strut connecting beam and a strut, and the lower fixing member and the strut connecting beam are connected by a fastener, and the fastener has a tightened state and a relaxed state. In the tightened state, the lower fixing member and the strut connecting beam are fixed to the guardrail column. In the relaxed state, the lower fixing member and the strut connecting beam can slide up and down along the guardrail column, the first end of the strut is rotatably connected to the strut connecting beam, and the second end of the strut is rotatably connected to the second hinge, so that the photovoltaic module installed on the guardrail can be directly adjusted in angle on the guardrail. However, in order to achieve angle adjustment, the support rod connecting beam needs to be able to slide up and down along the guardrail column, but multiple lower fixings need to be loosened before adjustment, and when adjusting upward, the weight of the entire photovoltaic module almost needs to be lifted, which makes adjustment more inconvenient. Utility Model Content

[0004] The purpose to be achieved by the utility model is to provide a photovoltaic power generation system installed on a balcony, which solves the problem of inconvenient inclination adjustment of photovoltaic components and makes the adjustment process easier and more labor-saving.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The cam is connected to the base frame of the photovoltaic module, and the cam is connected to the base frame by a hinged connection between the base frame and the photovoltaic module, and the cam is connected to the base frame by a hinged connection between the base frame and the photovoltaic module.

[0007] Preferably, the vertical slide rail is provided with a plurality of gear adjustment holes at intervals along the vertical direction, and the locking member is connected to the gear adjustment holes.

[0008] Preferably, the vertical slide rail is provided with a T-shaped slide groove with an opening facing forward, the vertical sliding block is provided with a T-shaped portion cooperating with the T-shaped slide groove, and the gear adjustment hole is provided on the back side of the T-shaped slide groove.

[0009] Preferably, the locking member is a locking bolt, the gear adjustment hole is a threaded hole, and the locking bolt is threadedly connected to the gear adjustment hole.

[0010] Preferably, the horizontal slide rail is provided with a T-shaped slide groove with an upward opening, and the horizontal sliding block is provided with a T-shaped portion that cooperates with the T-shaped slide groove.

[0011] Preferably, bearings are installed on both the vertical slider and the horizontal slider, and the bearings are in rolling fit with the vertical slide rail and the horizontal slide rail.

[0012] Preferably, the horizontal slider and the vertical slider are provided with a sliding portion, and the bearing is provided on the sliding portion.

[0013] Preferably, the vertical slide rail is fixed to the cross bar through a clamp, and the vertical slide rail and the clamp are fixed through bolts.

[0014] Preferably, the photovoltaic bracket also includes a diagonal support rod supported on the lower side of the horizontal slide rail, the horizontal slide rail and one end of the diagonal support rod are hinged through a first hinge seat, the other end of the diagonal support rod is connected to a second hinge seat, and the second hinge seat is fixed to the vertical slide rail.

[0015] Preferably, the balcony is provided with an energy storage device for storing the electrical energy generated by the photovoltaic modules and a charging control box connecting the photovoltaic modules and the energy storage device.

[0016] The utility model adopts the above technical solution, which has the following beneficial effects:

[0017] 1. The vertical rails are fixed perpendicularly to the two horizontal bars and secured to the balcony railing. The rear end of the horizontal rail is fixed to the bottom of the vertical rail, while the front end extends horizontally forward. The vertical and horizontal rails are arranged vertically and horizontally, respectively, to form a right-angled L-shaped assembly. The vertical rails are connected to vertical sliders, while the horizontal rails are connected to horizontal sliders. The vertical sliders are hingedly connected to upper pressure blocks connected to the upper side frame of the photovoltaic module, while the horizontal sliders are hingedly connected to lower pressure blocks connected to the lower side frame of the photovoltaic module. Therefore, when the vertical sliders slide along the vertical rails, they can drive the horizontal sliders along the horizontal rails to adjust the inclination angle of the photovoltaic module. Furthermore, the vertical rails are connected to locking members that lock the vertical sliders to the vertical rails. After the inclination angle is adjusted, the locking members secure the vertical sliders, restricting the horizontal sliders as well. This creates a stable triangular structure between the photovoltaic module and the horizontal and vertical rails, resulting in a fixed inclination angle between the photovoltaic module and the horizontal plane.

[0018] To adjust the tilt angle of the PV module, simply loosen the locking piece and pull the PV module upward, or gently hold the PV module to limit its sliding, and the vertical slider slides along the vertical rail, making adjustment easy. When adjusting the vertical slider upward, because the weight of the PV module is supported on the horizontal rail by the horizontal slider, the horizontal slider encounters very little resistance during adjustment. The PV module can be pulled upward with relatively little effort, and the horizontal slider slides along the horizontal rail, making the adjustment process even easier and more labor-saving.

[0019] 2. The vertical slide rail is provided with a number of gear adjustment holes at vertical intervals, and the locking parts are connected to the gear adjustment holes, so that multi-angle adjustment can be achieved. Different gear adjustment holes cooperate with the locking parts (locking bolts) to accurately fix the photovoltaic module at the set inclination angle.

[0020] 3. The vertical slider is equipped with a T-shaped slide, so the vertical slider will not separate when sliding along the vertical slide rail. In addition, since the gear adjustment hole is set on the back of the T-shaped slide, the locking piece can be locked or loosened on the balcony, which is convenient for operation.

[0021] 4. The locking part is a locking bolt, and the gear adjustment hole is a threaded hole. The locking bolt is threadedly connected to the gear adjustment hole, so it is easy to operate and the locking is reliable.

[0022] 5. Bearings are installed on both the vertical and horizontal sliders, and the bearings roll in conjunction with the vertical and horizontal rails. The horizontal and vertical sliders have sliding sections on which the bearings are mounted. This allows the vertical and horizontal sliders to slide smoothly, saving effort when adjusting the inclination angle.

[0023] 6. The vertical rails are fixed to the crossbars with clamps, and the rails and clamps are fixed with bolts. The clamp fixation method is easy to install and remove, and is conducive to replacement and maintenance.

[0024] 7. Since the photovoltaic bracket also includes a diagonal support rod supported on the lower side of the horizontal slide rail, the horizontal slide rail and one end of the diagonal support rod are hinged through a first hinge seat, and the other end of the diagonal support rod is connected to the second hinge seat, and the second hinge seat is fixed to the vertical slide rail. In this way, a stable triangular structure is formed between the horizontal slide rail, the diagonal support rod and the vertical slide rail to ensure that the horizontal slide rail is reliably fixed.

[0025] 8. The charging control box supplies the electricity generated by the photovoltaic panels to the electrical equipment in the building. When the photovoltaic system generates more electricity than the household electricity consumption, the remaining electricity can be stored in the energy storage battery. When the photovoltaic panels do not generate electricity at night or the mains power is cut off, the control module can release the electricity stored in the battery for use as an emergency power supply.

For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0041] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0042] like Figures 1 to 7 As shown, the utility model provides a photovoltaic power generation system installed on a balcony, wherein a guardrail 3 is installed on the balcony 2, wherein the guardrail is a conventional structure, and the guardrail 3 includes two horizontal bars 31 arranged parallel to each other and a vertical bar 32 cross-connected with the horizontal bars. The photovoltaic power generation system includes a photovoltaic module 100 and a photovoltaic bracket 1 for fixing the photovoltaic module 100 to the guardrail 3. The photovoltaic bracket 1 includes a vertical slide rail 11 and a horizontal slide rail 12, wherein the vertical slide rail 11 is fixed vertically and cross-fixed with the two horizontal bars 31, and the rear end of the horizontal slide rail 12 is fixed to the lower part of the vertical slide rail and the front end extends horizontally forward. The vertical slide rail 11 is connected to a vertical slider 14, and the horizontal slide rail 12 is connected to a horizontal slider 16. The vertical slider 14 is hinged to an upper pressure block 17, and the upper pressure block 17 is connected to the upper side frame of the photovoltaic module. The horizontal slider 16 is hinged to a lower pressure block 18, and the lower pressure block 18 is connected to the lower side frame of the photovoltaic module. The vertical slider 14 slides along the vertical slide rail 11 and drives the horizontal slider 16 to slide along the horizontal slide rail 12 to adjust the inclination angle of the photovoltaic assembly 100. The vertical slide rail 11 is connected to a locking member that locks the vertical slider 14 and the vertical slide rail 11.

[0043] In the above technical solution, the vertical slide rail is fixed perpendicularly to the two cross bars, and the vertical slide rail is fixed to the balcony guardrail. The rear end of the horizontal slide rail is fixed to the lower part of the vertical slide rail, and the front end extends horizontally forward, so that the vertical slide rail and the horizontal slide rail are arranged in the vertical and horizontal directions respectively, forming a right-angled L-shaped combination. Since the vertical slide rail is connected to the vertical slider, the horizontal slide rail is connected to the horizontal slider, the vertical slider is hinged with an upper pressure block, the upper pressure block is connected to the upper side frame of the photovoltaic module, and the horizontal slider is hinged with a lower pressure block, the lower pressure block is connected to the lower side frame of the photovoltaic module, therefore, when the vertical slider slides along the vertical slide rail, it can drive the horizontal slider to slide along the horizontal slide rail to adjust the inclination angle of the photovoltaic module. In addition, the vertical slide rail is connected to a locking member that locks the vertical slider to the vertical slide rail. After the vertical slider is fixed by the locking member, the horizontal slider is also restricted, forming a stable triangular structure between the photovoltaic module and the horizontal and vertical slide rails, so that a fixed inclination angle is formed between the photovoltaic module and the horizontal plane.

[0044] To adjust the tilt angle of the PV module, simply loosen the locking piece and pull the PV module upward, or gently hold the PV module to limit its sliding, and the vertical slider slides along the vertical rail, making adjustment easy. When adjusting the vertical slider upward, because the weight of the PV module is supported on the horizontal rail by the horizontal slider, the horizontal slider encounters very little resistance during adjustment. The PV module can be pulled upward with relatively little effort, and the horizontal slider slides along the horizontal rail, making the adjustment process even easier and more labor-saving.

[0045] Specifically, the vertical slide rail 11 is provided with a plurality of gear adjustment holes 112 at vertical intervals, and the locking member is connected to the gear adjustment hole 112. Multi-angle adjustment can be achieved, and the cooperation of different gear adjustment holes and locking members can accurately fix the photovoltaic module at the set inclination angle. The vertical slide rail 11 is provided with a T-shaped groove 111, and the vertical slider 11 is provided with a T-shaped portion that cooperates with the T-shaped groove, and the gear adjustment hole 112 is provided on the back of the T-shaped groove. Then, when the vertical slider slides along the vertical slide rail, the two will not separate. The locking member is a locking bolt 15, and the gear adjustment hole 112 is a threaded hole, and the locking bolt 15 is threadedly connected to the gear adjustment hole 112. In this way, the locking member can be locked or loosened on the balcony, and the vertical slider slides along the vertical slide rail. After the adjustment is completed, the locking bolt is tightened.

[0046] It is understandable that the structure of the locking member, as well as the gear adjustment and locking structure between the locking member and the vertical slide rail and the vertical slider can also be replaced by conventional structures in the prior art.

[0047] Similarly, the horizontal slide rail 12 is provided with a T-shaped slide groove, and the horizontal slider 16 is provided with a T-shaped portion 161 that cooperates with the T-shaped slide groove.

[0048] Furthermore, bearings 163 are mounted on both the vertical slider 14 and the horizontal slider 16, which roll in engagement with the vertical and horizontal guide rails 11 and 12. The horizontal slider 14 and the vertical slider 16 also have sliding portions 162 located outside the T-shaped guide grooves, with the bearings 163 mounted on these sliding portions. This allows for smooth sliding of the vertical and horizontal sliders, saving effort when adjusting the inclination angle.

[0049] Specifically, the vertical rail 11 is secured to the crossbar 31 via a clamp 19, which is bolted to the clamp 19. When installing the photovoltaic mount, the clamp secures the vertical rail to the crossbar and ensures its position on the crossbar remains unchanged. This clamping method facilitates installation and removal, and facilitates replacement and maintenance.

[0050] The photovoltaic support 1 also includes a diagonal brace 13, which is provided below the horizontal rail 12 for support. The horizontal rail 12 and the diagonal brace 13 are hinged at one end via a first hinge seat, and the other end of the diagonal brace 13 is connected to a second hinge seat, which is fixed to the bottom of the vertical rail. This creates a stable triangular structure between the horizontal rail, the diagonal brace, and the vertical rail, ensuring the secure fixation of the horizontal rail.

[0051] Additionally, the balcony 2 is equipped with an energy storage device 5 for storing the electricity generated by the photovoltaic modules, and a charging control box 6 connecting the photovoltaic modules and the energy storage device. The charging control box 6 is equipped with a control module for control. The energy storage device 5 and the charging control box 6 connecting the photovoltaic modules and the energy storage device are located near the wall 4 on one side of the balcony.

[0052] The energy storage device includes a battery rack and energy storage batteries placed within the rack. The battery rack is a multi-layered structure with multiple energy storage batteries placed in layers. The charging control box supplies the electricity generated by the photovoltaic panels to the building's electrical equipment. When the photovoltaic system's power generation exceeds household electricity consumption, the excess power is stored in the energy storage batteries. At night, when the photovoltaic panels are not generating electricity or the mains power is cut off, the control module releases the stored energy in the batteries for use as an emergency power source. This control principle is currently available.

[0053] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
