Description

Technical Field

[0001] This utility model relates to a photovoltaic curtain wall component and a photovoltaic curtain wall system, belonging to the field of photovoltaic curtain wall technology. Background Technology

[0002] Photovoltaic curtain walls are a new form of building-integrated photovoltaics (BIPV). They organically combine photovoltaic modules with traditional curtain walls, directly converting solar energy into electricity based on the principles of solar power generation. Photovoltaic curtain walls integrate solar energy into the overall design of modern buildings, creating a seamless and organic combination that forms a new type of architecture that integrates architecture, technology, and aesthetics. Photovoltaic curtain walls endow buildings with new functions and attributes, enabling them to provide energy while providing living space. They represent the mainstream direction for future solar power generation technology and building energy conservation. In current technologies, photovoltaic curtain walls installed on rooftops are often supported by brackets to ensure the photovoltaic panels face the sun, allowing them to receive sunlight and convert it into electricity.

[0003] A photovoltaic (PV) curtain wall assembly typically includes a support frame, PV panels, and a support plate. The PV panels are fixedly mounted on the support plate, which is positioned above the support frame. The left end of the support plate is rotatably connected to the left end of the support frame via a first pivot. The axis of the first pivot is horizontally positioned along the front-to-back direction. An angle adjustment mechanism is provided between the support plate and the support frame, allowing them to rotate relative to each other around the first pivot. This angle adjustment mechanism is used to adjust the tilt angle of the PV panel relative to the upper surface of the support frame. Traditional angle adjustment mechanisms typically consist of height-adjustable support columns on the front and rear sides of the support frame. The upper ends of these columns are hinged to the support plate. Each support column consists of two sections connected by multiple bolts. Adjustment is achieved by changing the relative position of the two sections and the bolt connection positions. This process is cumbersome, requiring the bolts on both sides of the support frame to be removed, the support plate to be manually lifted and lowered to adjust the angle, and then the bolts to be reconnected and fixed. This method is inefficient.

[0004] In addition, patent document CN221321390U discloses a building photovoltaic curtain wall structure, including two shells. A positioning seat is fixedly connected to the center of each of the two shells. A rotating block is rotatably connected to the positioning seat. A photovoltaic panel is fixedly connected to the end of the rotating block. A threaded rod is rotatably connected to the inside of each of the two shells. An adjusting handle is fixedly connected to the end of the threaded rod. A moving block is screwed onto the threaded rod. One end of a linkage rod is rotatably connected to the moving block. The other end of the linkage rod is rotatably connected to the bottom of the photovoltaic panel. A limiting post fixedly connected to the shell is slidably sleeved in the moving block. One end of a rotating rod 2 is rotatably connected to the outer wall of each of the two housings. The other end of each of the two rotating rods 2 is rotatably connected to a rotating rod 1. A rotating shaft is fixedly sleeved between the ends of the two rotating rods 1. Fixed plates are rotatably connected to both ends of the rotating shaft. An mounting plate is fixedly connected between the ends of the two fixed plates. A worm gear is fixedly sleeved on the outer wall of the rotating shaft. A worm is meshed with the bottom of the worm gear. The worm is rotatably connected to the mounting plate. An adjusting handle 2 is fixedly connected to the end of the worm. Adjusting handle one rotates the two threaded rods, which in turn drive the moving block to move along the limiting post. This moving block then deflects the linkage rod, and the top of the linkage rod causes the photovoltaic panel and its bottom rotating block one to deflect at a positioning seat. This allows for simultaneous left-right angle adjustment of the photovoltaic panels in both housings. Adjusting handle two then rotates the worm gear, which in turn rotates the worm wheel and the central shaft. This causes the two rotating rods one to rotate, and the end of rotating rod one drives rotating rod two, which in turn drives the housing and its photovoltaic panel to deflect vertically. While this solution is relatively convenient to operate, there is still significant room for improvement in ensuring the overall structural support reliability after adjustment to a specific position. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a photovoltaic curtain wall component that, while facilitating the adjustment of the tilt angle of the photovoltaic panels, also has good support reliability.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a photovoltaic curtain wall component, including a support frame, a photovoltaic panel, and a support plate. The photovoltaic panel is fixedly mounted on the support plate, and the support plate is mounted above the support frame. The left end of the support plate is rotatably connected to the left end of the support frame via a first pivot. The axis of the first pivot is horizontally arranged along the front-back direction. An angle adjustment mechanism is provided between the support plate and the support frame to allow them to rotate relative to each other around the first pivot. The support frame includes a rectangular frame composed of a left frame, a right frame, a front frame, and a rear frame. The angle adjustment mechanism includes a first knob, a first threaded rod, a first threaded cap, a connecting rod, a moving block, a first support rod, and a connecting block. The two ends of the first threaded rod are respectively rotatably connected to the middle of the left frame and the middle of the right frame of the support frame. The axis of the first threaded rod is perpendicular to the first pivot. The first knob is coaxially fixedly connected to the first threaded rod and located outside the right frame. The first threaded cap is threadedly screwed into the middle of the first threaded rod. The front and rear sides of the first threaded cap are respectively connected via... A connecting rod is fixedly connected to a movable block, which is slidably connected to the front and rear frames respectively. A first support rod is vertically fixed to the upper surface of the movable block. The upper end of the first support rod is hinged to the connecting block via a second pivot, which is parallel to the first pivot. The connecting block is slidably mounted on the support plate. The first support rod can be moved left and right by rotating the first threaded rod. The upper surfaces of the front and rear frames of the support frame are respectively provided with placement slots extending in the left and right direction. A toothed plate is installed in the placement slot through multiple spring telescopic rods spaced apart in the left and right direction. The axis of the spring telescopic rod is vertically set. The upper surface of the toothed plate has a first tooth, and the movable block has a second tooth. The first tooth and the second tooth are connected by a one-way transmission gear mechanism. When the first tooth and the second tooth are engaged, the movable block can only move from right to left. When the spring telescopic rod is in its natural state, the first tooth and the second tooth are engaged. When the toothed plate is pressed down, the first tooth and the second tooth can disengage.

[0007] A further preferred embodiment is that the movable block is a U-shaped block structure, with a movable limiting protrusion provided on the inner sidewall of the U-shaped block structure, and the front and rear frames are respectively provided with a first sliding groove that forms a sliding fit with the movable limiting protrusion.

[0008] A further preferred embodiment is that movable grooves are respectively opened on the front and rear sides of the lower surface of the support plate, and a second support rod is fixed between the inner walls of the two ends of the movable groove, and the connecting block is slidably sleeved on the second support rod.

[0009] A further preferred embodiment is that the front and rear ends of the upper surface of the left frame of the support frame are respectively fixed with hinged supports, and the two ends of the first pivot are respectively connected to the hinged supports.

[0010] A further preferred embodiment is that a support block is fixedly installed on the inner side of the right frame of the support frame, and a second threaded rod is mounted on the support block. The axis of the second threaded rod is parallel to the first pivot. A second bevel gear is coaxially fixed to one end of the second threaded rod, and a first bevel gear is coaxially fixed to the first threaded rod. The first bevel gear meshes with the second bevel gear. A second threaded cap is threadedly connected to the middle of the second threaded rod. The second threaded cap forms a sliding fit with the right frame of the support frame. A pointer is fixed to the upper side of the second threaded cap, and a scale is embedded on the upper surface of the right frame of the support frame. The position of the pointer corresponds to the position of the scale.

[0011] A further preferred embodiment is that the upper surface of the support plate has an installation groove corresponding to the photovoltaic panel, the photovoltaic panel is laid flat and installed inside the installation groove, and a cover plate made of light-transmitting glass is attached to the upper surface of the support plate, the cover plate completely covering the photovoltaic panel and the installation groove, and the cover plate is fixed to the support plate by a fixing component.

[0012] A further preferred embodiment is that multiple sets of fixing components are arranged circumferentially around the cover plate. Each set of fixing components includes a second knob, a third threaded rod, a threaded tube, a push block, a fixing block, a limit rod, a second spring, and a slider. The axis of the third threaded rod is set along the thickness direction of the cover plate, and a transmission chamber is provided on the cover plate. The third threaded rod is rotatably installed in the transmission chamber. The second knob is coaxially fixedly installed on the upper end of the third threaded rod and located outside the transmission chamber. The threaded tube is threadedly screwed onto the third threaded rod. The push block is fixed to the lower end of the threaded tube. The outer side of the threaded tube forms a sliding fit with the second sliding groove inside the transmission chamber through the slider. The fixing block is fixed to the lower surface of the cover plate. The fixing block has a telescopic groove inside, which is connected to the transmission chamber through the transmission cavity. The lower end of the push block passes through the transmission cavity. Multiple telescopic grooves are arranged circumferentially around the push block. A limit rod slides through each telescopic groove. The axis of the limit rod is... The limiting rod is perpendicular to the axis of the pushing block. The end of the limiting rod near the pushing block cooperates with the lower end of the pushing block to form a wedge mechanism. The limiting rod is fitted with a second spring. The telescopic groove has a spring mounting cavity adapted to the second spring. The outer wall of the limiting rod is fixedly provided with a spring limiting protrusion in the area where the spring mounting cavity is located. The second spring is installed between the end wall of the spring mounting cavity away from the transmission cavity and the spring limiting protrusion. The upper surface of the support plate has a fixing groove corresponding to each fixing block. The fixing block is engaged in the fixing groove. The inner side wall of the fixing groove has a limiting groove corresponding to each limiting rod. The rotation of the third threaded rod can make the pushing block move downward and drive the outer end of the limiting rod to move outside the telescopic groove, and make the outer end of the limiting rod engage in the limiting groove. When the pushing block moves upward by the rotation of the third threaded rod, the restoring force of the second spring can make the outer end of the limiting rod move out of the limiting groove.

[0013] A further preferred embodiment is that when the outer end of the limiting rod is engaged inside the limiting groove, the inner end face of the limiting rod and the outer side face of the pushing block form a planar contact parallel to the axis of the pushing block.

[0014] A further preferred embodiment is that the limiting rods are arranged at uniform intervals around the circumference of the pushing block.

[0015] A further preferred embodiment is that there are two sliders and two second slides, which are symmetrically arranged on both sides of the threaded tube.

[0016] Based on the aforementioned photovoltaic curtain wall components, this utility model also provides a photovoltaic curtain wall system, including an energy storage module and an energy conversion module. The energy conversion module is used to convert the direct current generated by the photovoltaic panel into alternating current, and the energy storage module is used to store the converted electrical energy.

[0017] The beneficial effects of this utility model are:

[0018] 1. During angle adjustment, the first knob drives the first threaded rod to rotate, which in turn moves the first threaded cap. The first threaded cap then moves the connecting rods fixed on both sides of the first threaded cap, which in turn moves the moving block. The moving block then moves the first support rod fixed on it. Since the upper end of the first support rod and the support plate are slidably hinged, the first support rod can adjust the angle of the photovoltaic panel while maintaining a vertical position, and both sides of the support plate are at the same height, thus improving installation stability. Furthermore, the first and second teeth are a one-way transmission gear mechanism. When the first and second teeth mesh, the moving block can only move from right to left, meaning the tilt angle of the photovoltaic panel can only be increased, not decreased. When the photovoltaic panel is adjusted to a specific position, the engagement of the first and second teeth provides a self-locking effect, preventing the angle of the support plate from changing when subjected to external impact, further improving support reliability. If it is necessary to reduce the tilt angle of the photovoltaic panel, which is equivalent to moving the moving block from left to right, then you only need to overcome the spring force of the spring telescopic rod and press the toothed plate downwards. After the first tooth and the second tooth disengage, you can rotate the first knob to drive the moving block to move normally. After moving to the target position, release the toothed plate.

[0019] II. This utility model utilizes a first bevel gear and a second bevel gear to enable the first threaded rod to rotate synchronously with the second threaded rod during rotation. This, in turn, causes the second threaded cap and a pointer fixed to the side of the second threaded cap to move synchronously. The relative position of the pointer and the scale allows for direct observation of the specific adjustment data, facilitating precise control of the adjustment angle. Photovoltaic curtain walls are typically arranged in multiple units simultaneously. This structural design ensures consistent angle adjustment between different photovoltaic curtain walls, preventing uneven energy output caused by inconsistent tilt angles among multiple photovoltaic curtain walls, thereby improving overall power generation efficiency.

[0020] Third, this utility model can ensure that the light-transmitting glass cover is stably installed above the photovoltaic panel through the fixing components, preventing it from shifting or falling off under the action of wind or other external forces. In addition, the support plate can provide additional physical protection to prevent external objects from directly contacting the photovoltaic panel and reduce the risk of damage. At the same time, the light-transmitting glass cover can effectively block the direct contact of dust and dirt, reduce the accumulation of dust on the surface of the photovoltaic panel, thereby improving the power generation efficiency.

[0028] The present invention will be further described below with reference to the accompanying drawings. It should be noted that the limitations on the front, back, left, and right directions in the present invention are merely for the purpose of facilitating understanding of the technical solution.

[0029] like Figures 1 to 6 As shown, the photovoltaic curtain wall assembly of this utility model includes a support frame 1, a photovoltaic panel 5, and a support plate 301. The photovoltaic panel 5 is fixedly mounted on the support plate 301, which is positioned above the support frame 1. The left end of the support plate 301 is rotatably connected to the left end of the support frame 1 via a first pivot. The axis of the first pivot is horizontally positioned along the front-back direction. An angle adjustment mechanism 2 is provided between the support plate 301 and the support frame 1, allowing them to rotate relative to each other around the first pivot. The support frame 1 includes a rectangular frame composed of a left frame, a right frame, a front frame, and a rear frame. The angle adjustment mechanism 2 includes a first knob 201, a first threaded rod 202, a first threaded cap 203, a connecting rod 204, a moving block 205, a first support rod 206, and a connecting block 304. The two ends of the first threaded rod 202 correspond to the left frame of the support frame 1, respectively. The first threaded rod 202 and the right side frame are rotatably connected. The axis of the first threaded rod 202 is perpendicular to the first pivot. The first knob 201 is coaxially fixedly connected to the first threaded rod 202 and located outside the right side frame. The first threaded cap 203 is threadedly screwed into the middle of the first threaded rod 202. The front and rear sides of the first threaded cap 203 are respectively fixedly connected to the moving blocks 205 through the connecting rods 204. The moving blocks 205 are slidably connected to the front frame and the rear frame respectively. The first support rod 206 is vertically fixed to the upper surface of the moving blocks 205 respectively. The upper end of the first support rod 206 is hinged to the connecting block 304 through the second pivot. The second pivot is parallel to the first pivot. The connecting block 304 is slidably mounted on the support plate 301. The rotation of the first threaded rod 202 can drive the first support rod 206 to move left and right. More specifically, the first threaded rod 202 and the moving block 205 constitute a screw-slider mechanism. The first knob 201 drives the first threaded rod 202 to rotate, the first threaded rod 202 drives the first threaded cap 203 to move, the first threaded cap 203 drives the connecting rods 204 fixed on both sides to move simultaneously, the connecting rods 204 drive the moving block 205 to move, and the moving block 205 drives the first support rod 206 fixed on it to move. Since the upper end of the first support rod 206 and the support plate 301 are slidably hinged (the connecting block 304 is slidable and has a second pivot), the first support rod 206 can adjust the angle of the photovoltaic panel 5 during its movement, while the first support rod 304 always remains vertical, and both sides of the support plate 301 are at the same height (the upper end of the first support rod 304 is at the same height and remains unchanged), which improves the stability of the installation and avoids the risk of the support plate 301 tilting.

[0030] The upper surfaces of the front and rear frames of the support frame 1 are respectively provided with placement slots 102 extending in the left and right directions. A toothed plate 104 is installed in the placement slot 102 through a plurality of spring telescopic rods 103 spaced apart in the left and right directions. The axis of the spring telescopic rods 103 is vertically arranged. The upper surface of the toothed plate 104 has a first tooth, and the moving block 205 is provided with a second tooth 2061. The first tooth and the second tooth 2061 are connected by a one-way transmission gear mechanism. When the first tooth and the second tooth 2061 are engaged, the moving block 205 can only move from right to left. When the spring telescopic rod 103 is in the natural state, the first tooth and the second tooth 2061 are engaged. When the toothed plate 104 is pressed down, the first tooth and the second tooth 2061 can disengage. The spring telescopic rod 103 is a conventional set of parts, typically consisting of a telescopic rod fixing sleeve, a telescopic rod movable column, and a spring. The telescopic rod fixing sleeve and the telescopic rod movable column are slidably sleeved together, allowing for adjustment of the axial length. The spring is sleeved on the outer circumference, and the overall axial length of the telescopic rod fixing sleeve and the telescopic rod movable column is adjustable by controlling the spring compression. In the embodiment shown in the accompanying drawings of this utility model, the lower end of the telescopic rod fixing sleeve is fixedly disposed at the bottom of the placement groove 102, and the upper end of the telescopic rod movable column is fixedly connected to the lower surface of the toothed plate 104. The two ends of the spring are correspondingly connected and disposed between the bottom of the placement groove 102 and the lower surface of the toothed plate 104. Figure 5 It can be seen that the left side of both the first and second teeth 2061 are vertical, while the right side is inclined. When the first and second teeth 2061 are engaged, the moving block 205 can only move from right to left, meaning it can only increase the tilt angle of the photovoltaic panel 5 and the support plate 301, not decrease it. When the photovoltaic panel 301 is adjusted to a specific position, the engagement of the first and second teeth 2061 acts as a self-locking mechanism, preventing the support plate 301 from changing its angle when subjected to external impact, thus further improving the reliability of the support. It is understandable that the weight of the support plate 301 and the photovoltaic panel 5 causes the moving block 205 to tend to move to the right, not to the left. Therefore, the engagement method of the first and second teeth 2061 fully ensures the overall structural reliability. If it is necessary to reduce the tilt angle of the photovoltaic panel 5, that is, to make the moving block 205 move from left to right, it is only necessary to overcome the spring force of the spring telescopic rod 103 and press the toothed plate 104 down. After the first tooth and the second tooth 2061 are disengaged, the moving block 205 can be moved normally by rotating the first knob 201. After moving to the target position, the toothed plate 104 can be released.

[0031] The sliding guide structure of the movable block 205 can take various forms, as long as it ensures that the movable block 205 can move horizontally in the left-right direction. A preferred embodiment is a U-shaped block structure, with a movement limiting protrusion on the inner wall of the U-shaped block structure. The front and rear frames are each provided with a first sliding groove 101 that slides into the movement limiting protrusion. The cooperation between the movement limiting protrusion and the first sliding groove 101 makes the structure more reliable, ensuring that the movable block 205 always maintains a reliable limiting connection with the front and rear frames. Correspondingly, the bottom of the U-shaped groove in the U-shaped block structure is used to accommodate the second tooth 2061.

[0032] The sliding guide structure of the connecting block 304 can take many forms. To make the structure simple and reliable, the preferred solution is that the front and rear sides of the lower surface of the support plate 301 are respectively provided with movable grooves 302, and the inner walls of the two ends of the movable groove 302 are fixed with a second support rod 303, and the connecting block 304 is slidably sleeved on the second support rod 303.

[0033] The first pivot can be set on the left side of the support frame 1, or it can be set on the left end of the front side and the left end of the rear side. In order to make the structure simple and reliable, the preferred solution is that the front end and the rear end of the upper surface of the left side of the support frame 1 are respectively fixed with hinged supports, and the two ends of the first pivot are respectively connected to the hinged supports.

[0034] In some preferred embodiments, a support block 208 is fixedly installed on the inner side of the right frame of the support frame 1. A second threaded rod 209 is mounted on the support block 208. The axis of the second threaded rod 209 is parallel to the first pivot. A second bevel gear 210 is coaxially fixed to one end of the second threaded rod 209. A first bevel gear 207 is coaxially fixed to the first threaded rod 202. The first bevel gear 207 meshes with the second bevel gear 210. A second threaded cap 211 is threadedly connected to the middle of the second threaded rod 209. The second threaded cap 211 forms a sliding fit with the right frame of the support frame 1. A pointer 212 is fixed to the upper side of the second threaded cap 211. A scale 105 is embedded on the upper surface of the right frame of the support frame 1. The pointer 212 corresponds to the position of the scale 105. With this structure, the first threaded rod 202 can drive the second threaded rod 209 to rotate synchronously during rotation, thereby causing the second threaded cap 211 and the pointer 212 fixed to the side of the second threaded cap 211 to move synchronously. The specific adjustment data can be visually observed through the relative position of the pointer 212 and the scale 105, which is beneficial for precise control of the adjustment angle. Photovoltaic curtain walls are usually arranged in multiples simultaneously. This structural design ensures the consistency of angle adjustment between different photovoltaic curtain walls, avoiding uneven energy output caused by inconsistent tilt angles of multiple photovoltaic curtain walls, thus improving overall power generation efficiency. To effectively ensure the reliability of the support structure for the second threaded rod 209, two support blocks 208 can be arranged side-by-side. In some embodiments, only one support block 208 can be provided, with one end of the second threaded rod 209 rotated and supported by the support block 208, and the other end rotated and supported by the corresponding front or rear frame.

[0035] In some preferred embodiments, the upper surface of the support plate 301 has a mounting groove corresponding to the photovoltaic panel 5. The photovoltaic panel 5 is laid flat inside the mounting groove. A light-transmitting glass cover plate 305 is attached to the upper surface of the support plate 301, completely covering the photovoltaic panel 5 and the mounting groove. The cover plate 305 is fixed to the support plate 301 by a fixing component 4. The fixing component 4 ensures that the light-transmitting glass cover plate 305 is securely installed above the photovoltaic panel 5, preventing displacement or detachment under wind or other external forces. Together with the support plate 301, it provides additional physical protection, preventing external objects from directly contacting the photovoltaic panel 5 and reducing the risk of damage. Simultaneously, the light-transmitting glass cover plate 305 effectively blocks direct contact with dust and dirt, reducing dust accumulation on the surface of the photovoltaic panel 5, thereby improving power generation efficiency.

[0036] The fixing component 4 can take various forms, such as bolted connections. For greater structural reliability, a preferred arrangement is to have multiple sets of fixing components 4 spaced circumferentially around the cover plate 305. Each set of fixing components 4 includes a second knob 401, a third threaded rod 402, a threaded tube 403, a push block 404, a fixing block 405, a limit rod 407, a second spring 408, and a slider 409. The axis of the third threaded rod 402 is aligned along the thickness of the cover plate 305. A transmission chamber 306 is provided on the cover plate 305, and the third threaded rod 402 is rotatably mounted within the transmission chamber 306. The second knob 401 is coaxially fixed to the upper end of the third threaded rod 402 and located outside the transmission chamber 306. The threaded tube 403 is threaded onto the third threaded rod 402, and the push block 404 is fixed to the lower end of the threaded tube 403. The outer side of the threaded tube 403 is connected to the slider 409. 9 forms a sliding fit with the second sliding groove inside the transmission chamber 306. The fixing block 405 is fixed to the lower surface of the cover plate 305. The fixing block 405 has a telescopic groove 406 inside. The telescopic groove 406 is connected to the transmission chamber 306 through the transmission cavity. The lower end of the push block 404 passes through the transmission cavity. Multiple telescopic grooves 406 are arranged circumferentially around the push block 404. A limiting rod 407 is correspondingly slidably passed through the inside of each telescopic groove 406. The axial direction of the limiting rod 407 is perpendicular to the axis of the push block 404. The end of the limiting rod 407 near the push block 404 cooperates with the lower end of the push block 404 to form a wedge mechanism. That is, the lower end of the push block 404 has an active inclined surface, and the end of the limiting rod 407 has a driven inclined surface. The wedge mechanism is used to convert the axial movement of the push block 404 into the linear movement of the limiting rod 407 in the radial direction of the push block 404. The limiting rod 407 is fitted with a second spring 408. The telescopic groove 406 has a spring mounting cavity adapted to the second spring 408. A spring limiting protrusion is fixedly provided on the outer wall of the limiting rod 407 in the area where the spring mounting cavity is located. The second spring 408 is installed between the end wall of the spring mounting cavity away from the transmission cavity and the spring limiting protrusion. The upper surface of the support plate 301 has a fixing groove 307 corresponding to each fixing block 405. The fixing block 405 is snapped into the fixing groove 307. The inner side wall of the fixing groove 307 has a groove corresponding to the limiting rod. The corresponding limiting groove 308 of 407 allows the pushing block 404 to move downward by rotating the third threaded rod 402, which in turn moves the outer end of the limiting rod 407 to the outside of the telescopic groove 406, and the outer end of the limiting rod 407 is engaged inside the limiting groove 308. The outer end of the limiting rod 407 is equivalent to the end away from the pushing block 404. When the pushing block 404 moves upward by rotating the third threaded rod 402, the restoring force of the second spring 408 can cause the outer end of the limiting rod 407 to move out of the limiting groove 308.In specific operation, firstly, the second knob 401 drives the third threaded rod 402 to rotate, which in turn drives the push block 404 to move upward, ensuring that the reset force of the second spring 408 can cause the outer end of the limit rod 407 to retract into the telescopic groove 406. At this time, the fixing block 405 can be properly engaged in the inside of the fixing groove 307. Then, the second knob 401 is rotated in the opposite direction to drive the push block 404 to move downward. The push block 404 drives the limit rod 407 to move according to the principle of the wedge mechanism. The outer end of the limit rod 407 moves to the outside of the telescopic groove 406, and finally the outer end of the limit rod 407 is engaged in the inside of the limit groove 308, forming a stable and reliable limiting structure. To make the structure more reliable, when the outer end of the limiting rod 407 is engaged inside the limiting groove 308, the inner end face of the limiting rod 407 and the outer side face of the pushing block 404 form a planar contact that is parallel to the axis of the pushing block 404. That is, the contact surface of the two is parallel to the axis of the pushing block 404. For details, please refer to the relevant documentation. Figure 6 .

[0037] To make the structure simpler and more reliable, the limiting rods 407 are arranged at uniform intervals around the push block 404 in the circumference.

[0038] To simplify the structure, there are two sliders 409 and two second slides, which are symmetrically arranged on both sides of the threaded tube 403.

[0039] Based on the aforementioned photovoltaic curtain wall components, this utility model also provides a photovoltaic curtain wall system, including an energy storage module and an energy conversion module. The energy conversion module is used to convert the direct current generated by the photovoltaic panel 5 into alternating current, and the energy storage module is used to store the converted electrical energy.

[0040] The overall operation of this utility model is as follows: First, the support frame 1 is placed in the designated position. Then, the worker places the photovoltaic panel 5 in the installation groove opened on the surface of the support plate 301. Next, the worker overlaps the cover plate 305 on the surface of the support plate 301 and makes the fixing block 405 snap into the corresponding fixing groove 307. Then, the worker turns the second knob 401, which drives the third threaded rod 402 to rotate. The third threaded rod 402 drives the threaded tube 403 to move. The threaded tube 403 drives the push block 404 to move synchronously. Since the contact surfaces of the push block 404 and the limiting rod 407 are both inclined surfaces, the push block 404 can push the limiting rod 407 to move during the movement. When one end of the limiting rod 407 is snapped into the limiting groove 308, the worker can stop turning the second knob 401 and complete the initial installation of the photovoltaic panel 5.

[0041] Then, the staff installs the support frame 1 in the designated position. When it is necessary to adjust the angle of the photovoltaic panel 5, simply turn the first knob 201 to rotate the first threaded rod 202. The first threaded rod 202 moves the first threaded cap 203, which in turn moves the connecting rods 204 fixed on both sides. The connecting rods 204 move the moving block 205, which in turn moves the first support rod 206 fixed on its surface. Since the upper end of the first support rod 206 and the support plate 301 are slidably hinged, the angle of the photovoltaic panel 5 can be adjusted during the movement of the first support rod 206. While ensuring the same height on both sides of the support frame 1, the stability of the installation is improved. At the same time, the rotation of the first threaded rod 202 can drive the first bevel gear 207 to rotate, and the first bevel gear 207 drives the second bevel gear 210 to rotate, thereby driving the second threaded rod 209 to rotate synchronously. This causes the second threaded cap 211 and the pointer 212 fixed on the side of the second threaded cap 211 to move synchronously. The relative position of the pointer 212 and the scale 105 is used to observe and adjust the data, avoiding uneven energy output caused by inconsistent tilt angles of multiple photovoltaic curtain walls, and improving the overall power generation efficiency.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
