Description

Technical Field

[0001] The present invention relates to a photovoltaic curtain wall component and a photovoltaic curtain wall system, belonging to the technical field of photovoltaic curtain walls. Background Art

[0002] A photovoltaic curtain wall is a new form of the application of building-integrated photovoltaics. That is, on the basis of a traditional curtain wall, photovoltaic components are organically combined. According to the principle of solar power generation, solar energy is directly converted into electrical energy. The photovoltaic curtain wall incorporates solar energy into the overall design of modern buildings, and they are organically and perfectly combined with each other, thus forming a new type of building that integrates architecture, technology, and aesthetics. The photovoltaic curtain wall endows the building with new functions and new attributes. It enables the building to provide energy while being inhabited by people. It is the mainstream direction of the development of future solar power generation technology and building energy conservation. In the prior art, when a photovoltaic curtain wall is installed on a roof, a bracket is often used to support it so that the photovoltaic panel faces the sun, thereby obtaining sunlight irradiation and converting it into electrical energy.

[0003] A photovoltaic curtain wall component usually includes a support frame, a photovoltaic panel, and a support plate. The photovoltaic panel is fixedly arranged on the support plate. The support plate is arranged above the support frame. The left end of the support plate is rotationally connected to the left end of the support frame through a first pivot. The axis of the first pivot is horizontally arranged along the front-rear direction. An angle adjustment mechanism for causing relative rotation between the two around the first pivot is arranged between the support plate and the support frame. The angle adjustment mechanism is used to adjust the inclination angle of the photovoltaic panel relative to the upper surface of the support frame. The traditional angle adjustment mechanism usually sets height-adjustable support and fixing columns on the front side and the rear side of the support frame respectively. The upper end of the support and fixing column is hinged to the support plate. The support and fixing column is composed of two sections of fixing columns. The two sections of fixing columns are connected and fixed by a plurality of bolts. The adjustment operation is realized by changing the relative position between the two sections of fixing columns and the bolt connection position. The operation process is relatively cumbersome. That is, first, the bolts on both sides of the support frame are disassembled, and the height of the support plate is adjusted by manually lifting and placing the support plate to realize the angle change, and then the bolts are reconnected and fixed, and the working efficiency is relatively low.

[0004] In addition, a patent document with publication number CN221321390U discloses a building photovoltaic curtain wall structure, including two shells, each of which is fixedly connected to a positioning seat at the internal center position of the two shells, a rotating block is rotatably connected to the positioning seat, and a photovoltaic panel is fixedly connected to the end of the rotating block, and a threaded rod is rotatably connected to the interior of the two shells, an adjustment handle is fixedly connected to the end of the threaded rod, a moving block is screwed and sleeved on the threaded rod, one end of a linkage rod is rotatably connected to the moving block, and the other end of the linkage rod is rotatably connected to the bottom of the photovoltaic panel, and a limiting column fixedly connected to the shell is slidably sleeved in the moving block. One end of the rotating rod 2 is rotatably connected to the outer wall of the two shells, and the other end of the two rotating rods 2 is rotatably connected to the rotating rod 1, a rotating shaft is fixedly sleeved between the ends of the two rotating rods 1, both ends of the rotating shaft are rotatably connected to a fixing plate, a mounting plate is fixedly connected between the ends of the two fixing plates, a worm wheel is fixedly sleeved on the outer wall of the rotating shaft, a worm is meshingly connected to the bottom of the worm wheel, the worm is rotatably connected to the mounting plate, and an adjusting handle 2 is fixedly connected to the end of the worm. By adjusting the rotation of handle 1, the two threaded rods can be driven to rotate, and the rotation of the threaded rod can drive the moving block to move along the limit column, so that the moving block can drive the linkage rod to deflect, and the top of the linkage rod can drive the photovoltaic panel and the rotating block 1 at the bottom thereof to deflect at a location on the positioning seat, so that the photovoltaic panels in the two shells can be adjusted in the left and right directions at the same time, and then the worm can be driven to rotate by adjusting handle 2, so that the worm can drive the worm wheel and the rotating shaft at the center position to rotate, so that the two rotating rods 1 can be driven to rotate, and the rotating rod 2 can be driven to rotate by the end of the rotating rod 1, so that the shell and the photovoltaic panel therein can be driven to deflect in a certain direction in the vertical direction by the end of the rotating rod 2. Although the adjustment operation of this scheme is relatively convenient, after adjusting to a specific position, there is still a lot of room for improvement in how to ensure the support reliability of the overall structure. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a photovoltaic curtain wall assembly which can facilitate the adjustment of the inclination angle of the photovoltaic panels while having good supporting reliability.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a photovoltaic curtain wall component, including a support frame, a photovoltaic panel, and a support plate. The photovoltaic panel is fixedly arranged on the support plate, and the support plate is arranged above the support frame. The left end of the support plate is rotationally connected to the left end of the support frame through a first pivot. The axis of the first pivot is horizontally arranged along the front-rear direction. An angle adjustment mechanism is arranged between the support plate and the support frame to cause relative rotation between the two 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 nut, a connecting rod, a moving block, a first support rod, and a connecting block. The two ends of the first threaded rod are respectively rotationally connected to the middle parts of the left frame and 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 and fixedly connected to the first threaded rod and is located outside the right frame; the first threaded nut is threadedly connected to the middle part of the first threaded rod. The front side and the rear side of the first threaded nut are respectively fixedly connected with a moving block through a connecting rod. The moving blocks are respectively slidably connected to the front frame and the rear frame. The first support rods are vertically arranged and are respectively fixedly arranged on the upper surfaces of the moving blocks. The upper ends of the first support rods are hinged to the connecting block through a second pivot. The second pivot is parallel to the first pivot. The connecting block is slidably arranged on the support plate. By rotating the first threaded rod, the first support rod can be driven to move left and right; on the upper surfaces of the front frame and the rear frame of the support frame, placing grooves extending in the left-right direction are respectively provided. Tooth plates are installed in the placing grooves through a plurality of spring telescopic rods spaced along the left-right direction. The axes of the spring telescopic rods are vertically arranged. The upper surface of the tooth plate has first teeth. Second teeth are arranged on the moving block. A one-way transmission tooth mechanism is formed between the first teeth and the second teeth. When the first teeth and the second teeth are engaged, the moving block can only move from right to left; when the spring telescopic rod is in a natural state, the first teeth and the second teeth are engaged; when the tooth plate is pressed down, the first teeth and the second teeth can be disengaged.

[0007] A further preferred solution is that the moving block is of a U-shaped block structure. Moving limit protrusions are arranged on the inner side walls of the U-shaped block structure. The front frame and the rear frame are respectively provided with first chutes that form sliding fits with the moving limit protrusions.

[0008] A further preferred solution is that on the front side and the rear side of the lower surface of the support plate, activity grooves are respectively provided. Second support rods are fixed between the inner walls at both ends of the activity grooves. The connecting block is slidably sleeved on the second support rods.

[0009] A further preferred solution is that at the front end and the rear end of the upper surface of the left frame of the support frame, hinge supports are respectively fixed. The two ends of the first pivot are respectively connected to the hinge supports.

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

[0011] A further preferred solution is that an installation groove corresponding to the photovoltaic panel is formed on the upper surface of the support plate. The photovoltaic panel is laid and installed inside the installation groove. A cover plate made of light-transmitting glass is attached to the upper surface of the support plate. The cover plate completely covers the photovoltaic panel and the installation groove, and the cover plate is fixed on the support plate through a fixing component.

[0012] A further preferred solution is that multiple sets of fixing components are arranged at intervals around the circumference of the cover plate. Each set of fixing components includes a second knob, a third threaded rod, a threaded tube, a pushing block, a fixing block, a limiting rod, a second spring and a slider. The axis of the third threaded rod is arranged along the thickness direction of the cover plate. A transmission cavity is formed on the cover plate, and the third threaded rod is rotatably installed in the transmission cavity; the second knob is coaxially and fixedly installed at the upper end of the third threaded rod and is located outside the transmission cavity; the threaded tube is threadedly screwed on the third threaded rod, and the pushing block is fixed at 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 cavity through the slider. The fixing block is fixed on the lower surface of the cover plate. An expansion slot is formed inside the fixing block. The expansion slot is communicated with the transmission cavity through a transmission cavity. The lower end of the pushing block penetrates inside the transmission cavity. A plurality of expansion slots are arranged at intervals around the circumference of the pushing block. A limiting rod is slidably inserted into each expansion slot correspondingly. The axial direction of the limiting rod is perpendicular to the axis of the pushing block. The end of the limiting rod close to the pushing block cooperates with the lower end of the pushing block to form a wedge mechanism. The limiting rod is sleeved with a second spring. A spring installation cavity adapted to the second spring is provided inside the expansion slot. A spring limiting protrusion is fixedly arranged on the outer side wall of the limiting rod in the area where the spring installation cavity is located. The second spring is installed between the end wall of the spring installation cavity far from the transmission cavity and the spring limiting protrusion; fixing grooves corresponding to each fixing block are formed on the upper surface of the support plate. The fixing block is clamped inside the fixing groove. A limiting groove corresponding to each limiting rod is formed on the inner side wall of the fixing groove. By rotating the third threaded rod, the pushing block can be moved downward, and the outer end of the limiting rod can be driven to move out of the expansion slot and be clamped inside the limiting groove; when the pushing block is moved upward by rotating the third threaded rod, the reset elastic force of the second spring can make the outer end of the limiting rod move out of the limiting groove.

[0013] A further preferred solution is that when the outer end of the limit rod is clamped inside the limit groove, a plane contact parallel to the axis of the push block is formed between the inner end face of the limit rod and the outer side face of the push block.

[0014] A further preferred solution is that the limit rods are arranged at equal intervals circumferentially around the push block.

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

[0016] On the basis of the above photovoltaic curtain wall assembly, the present invention also provides a photovoltaic curtain wall system, including a power storage module and a power conversion module. The power conversion module is used to convert the direct current generated by the photovoltaic panel into alternating current, and the power storage module is used to store the converted electric energy.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. When adjusting the angle, the first knob drives the first threaded rod to rotate, the first threaded rod drives the first threaded nut to move, the first threaded nut drives the connecting rods fixed on both sides thereof to move simultaneously, the connecting rods drive the moving block to move, and the moving block drives the first support rod fixed thereon to move. Since the upper end of the first support rod and the support plate are slidably hinged, therefore, during the movement of the first support rod, while being able to adjust the angle of the photovoltaic panel, the first support rod always maintains a vertical state, and both sides of the support plate are at the same height, improving the installation stability. In addition, between the first tooth and the second tooth is a one-way transmission tooth mechanism. When the first tooth and the second tooth are engaged, the moving block can only move from right to left, that is, only the inclination angle of the photovoltaic panel can be increased and cannot be decreased. When the photovoltaic panel is adjusted to a specific position, the cooperation between the first tooth and the second tooth can play a self-locking role, avoiding the change of the angle when the support plate is impacted by external force, and further improving the support reliability. If it is necessary to reduce the inclination angle of the photovoltaic panel, that is, to make the moving block move from left to right, only need to overcome the spring force of the spring telescopic rod to press the tooth plate downward. After the first tooth and the second tooth are disengaged, the moving block can be driven to move normally by rotating the first knob. After moving to the target position, release the tooth plate.

[0019] 2. Through the first bevel gear and the second bevel gear of the present invention, the first threaded rod can drive the second threaded rod to rotate synchronously during the rotation process, so as to drive the second threaded nut and the pointer fixed on the side of the second threaded nut to move synchronously. The specific adjustment data can be visually observed through the relative position of the pointer and the scale, which is beneficial to accurately control the adjustment angle. Photovoltaic curtain walls are usually arranged in multiple at the same time. After adopting this structural design, the angle adjustment consistency between different photovoltaic curtain walls can be ensured, avoiding uneven energy output caused by inconsistent inclination angles of multiple photovoltaic curtain walls, thereby improving the overall power generation efficiency.

[0020] III. Through the fixing component, the present invention can ensure that the light-transmitting glass cover plate is stably installed above the photovoltaic panel, preventing displacement or detachment under the action of wind force or other external forces. And in cooperation with the support plate, it can provide additional physical protection, preventing external objects from directly contacting the photovoltaic panel, reducing the risk of damage. At the same time, the light-transmitting glass cover plate can effectively block the direct contact of dust and dirt, reducing the dust accumulation on the surface of the photovoltaic panel, thereby improving the power generation efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the definitions of the front, rear, left, right and other orientations in the present invention are only for facilitating the understanding of the technical solution.

[0029] As Figures 1 to 6 shown, the photovoltaic curtain wall component described in the present invention includes a support frame 1, a photovoltaic panel 5 and a support plate 301. The photovoltaic panel 5 is fixedly arranged on the support plate 301. The support plate 301 is arranged above the support frame 1. The left end of the support plate 301 is rotationally connected to the left end of the support frame 1 through a first pivot. The axis of the first pivot is horizontally arranged along the front-rear direction. An angle adjustment mechanism 2 for causing relative rotation between the two around the first pivot is arranged between the support plate 301 and the support frame 1. 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 are respectively rotationally connected to the middle parts of the left frame and the right frame of the support frame 1. The axis of the first threaded rod 202 is perpendicular to the first pivot. The first knob 201 is coaxially and fixedly connected to the first threaded rod 202 and is located outside the right frame; the first threaded cap 203 is threadedly connected to the middle part of the first threaded rod 202. The front side and the rear side of the first threaded cap 203 are respectively fixedly connected with a moving block 205 through a connecting rod 204. The moving blocks 205 are respectively slidably connected to the front frame and the rear frame. The first support rods 206 are vertically arranged and are respectively fixedly arranged on the upper surfaces of the moving blocks 205. The upper ends of the first support rods 206 are hinged to the connecting block 304 through a second pivot. The second pivot is parallel to the first pivot. The connecting block 304 is slidably arranged on the support plate 301. By rotating the first threaded rod 202, the first support rod 206 can be driven 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 thereof to move simultaneously. The connecting rods 204 drive the moving blocks 205 to move. The moving blocks 205 drive the first support rods 206 fixed thereon to move. Since the upper ends of the first support rods 206 and the support plate 301 are slidably hinged (the connecting block 304 is slidable and has a second pivot), therefore, during the movement of the first support rods 206, while the angle of the photovoltaic panel 5 can be adjusted, the first support rods 304 always remain in a vertical state, and both sides of the support plate 301 are at the same height (the upper ends of the first support rods 304 are at the same height and remain unchanged), improving the installation stability and avoiding the risk of the support plate 301 being skewed.

[0030] On the upper surfaces of the front and rear frames of the support frame 1, placing grooves 102 extending in the left - right direction are respectively provided. In the placing grooves 102, a toothed plate 104 is installed through a plurality of spring telescopic rods 103 spaced in the left - right direction. The axes of the spring telescopic rods 103 are vertically arranged. The upper surface of the toothed plate 104 has first teeth, and a second tooth 2061 is provided on the moving block 205. A one - way transmission tooth mechanism is formed between the first teeth and the second tooth 2061. When the first teeth 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 a natural state, the first teeth and the second tooth 2061 are engaged; when the toothed plate 104 is pressed down, the first teeth and the second tooth 2061 can be disengaged. The spring telescopic rod 103 is a conventional complete set of parts, usually composed of a telescopic rod fixed sleeve, a telescopic rod movable column, and a spring. The telescopic rod fixed sleeve and the telescopic rod movable column are slidably sleeved so that the axial length is adjustable. The spring is sleeved on the outer periphery, and the adjustable axial length of the whole telescopic rod fixed sleeve and the telescopic rod movable column is realized by controlling the compression amount of the spring. In the embodiment shown in the drawings of the present invention, the lower end of the telescopic rod fixed sleeve is fixedly arranged at the bottom of the placing 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 between the bottom of the placing groove 102 and the lower surface of the toothed plate 104. From Figure 5 It can be seen that the left - hand sides of both the first teeth and the second tooth 2061 are vertical surfaces, and the right - hand sides are inclined surfaces. When the first teeth and the second tooth 2061 are engaged, the moving block 205 can only move from right to left, that is, only the inclination angles of the photovoltaic panel 5 and the support plate 301 can be increased, and cannot be decreased. When the photovoltaic panel 301 is adjusted to a specific position, the cooperation between the first teeth and the second tooth 2061 can play a self - locking role to avoid the change of the angle of the support plate 301 when it is impacted by an external force, further improving the support reliability. It can be understood that the self - gravity of components such as the support plate 301 and the photovoltaic panel 5 all makes the moving block 205 tend to move to the right rather than to the left. Therefore, by adopting the above - mentioned cooperation mode between the first teeth and the second tooth 2061, the reliability of the overall structure can be fully guaranteed. If it is necessary to reduce the inclination angle of the photovoltaic panel 5, that is, to make the moving block 205 move from left to right, only need to overcome the spring force of the spring telescopic rod 103 to press down the toothed plate 104. After the first teeth and the second tooth 2061 are disengaged, the moving block 205 can be driven to move normally by rotating the first knob 201. After moving to the target position, release the toothed plate 104.

[0031] The sliding guiding structure of the moving block 205 can have various forms, as long as it ensures that the moving block 205 can move horizontally in the left-right direction. Preferably, the moving block 205 is a U-shaped block structure, and moving limit protrusions are provided on the inner side walls of the U-shaped block structure. First sliding grooves 101 that form a sliding fit with the moving limit protrusions are respectively provided on the front frame and the rear frame. The cooperation between the moving limit protrusions and the first sliding grooves 101 can make the structure more reliable, and the moving block 205 always maintains a reliable limit connection state with the front frame and the rear frame. Correspondingly, the bottom of the U-shaped groove of the U-shaped block structure is used to arrange the second teeth 2061.

[0032] The sliding guiding structure of the connecting block 304 can have various forms. To make the structure simple and reliable, preferably, movable grooves 302 are respectively formed on the front side and the rear side of the lower surface of the support plate 301, and second support rods 303 are fixed between the inner walls at both ends of the movable grooves 302. The connecting block 304 is slidably sleeved on the second support rods 303.

[0033] The first pivot can be arranged on the left frame of the support frame 1, or can be correspondingly arranged at the left ends of the front frame and the rear frame. To make the structure simple and reliable, preferably, hinge supports are respectively fixed at the front end and the rear end of the upper surface of the left frame of the support frame 1, and both ends of the first pivot are respectively connected to the hinge supports correspondingly.

[0034] In some preferred examples, a support block 208 is fixedly arranged on the inner side surface of the right frame of the support frame 1. A second threaded rod 209 is rotatably arranged on the support block 208. The axis of the second threaded rod 209 is parallel to the first pivot axis. A second bevel gear 210 is coaxially fixed at one end of the second threaded rod 209. A first bevel gear 207 is coaxially fixed on the first threaded rod 202. The first bevel gear 207 meshes with the second bevel gear 210. A second threaded nut 211 is threadedly connected to the middle of the second threaded rod 209. The second threaded nut 211 forms a sliding fit with the right frame of the support frame 1. A pointer 212 is fixed on the upper side of the second threaded nut 211. A scale 105 is embedded in the upper surface of the right frame of the support frame 1. The position of the pointer 212 corresponds to that of the scale 105. After adopting this structural method, the second threaded rod 209 can be driven to rotate synchronously during the rotation of the first threaded rod 202, so as to drive the second threaded nut 211 and the pointer 212 fixed on the side surface of the second threaded nut 211 to move synchronously. The specific adjustment data can be visually observed through the relative positions of the pointer 212 and the scale 105, which is beneficial to accurately control the adjustment angle. Usually, multiple photovoltaic curtain walls are arranged simultaneously. After adopting this structural design, the consistency of the angle adjustment between different photovoltaic curtain walls can be ensured, and the uneven energy output caused by inconsistent inclination angles of multiple photovoltaic curtain walls can be avoided, thereby improving the overall power generation efficiency. To effectively ensure the reliability of the support structure of the second threaded rod 209, two support blocks 208 can be arranged in parallel. In some embodiments, only one support block 208 can also be provided. One end of the second threaded rod 209 is rotatably supported by the support block 208, and the other end can be rotatably supported by the front frame or the rear frame correspondingly.

[0035] In some preferred examples, an installation groove corresponding to the photovoltaic panel 5 is formed on the upper surface of the support plate 301. The photovoltaic panel 5 is flatly installed inside the installation groove. A cover plate 305 made of light-transmitting glass is attached to the upper surface of the support plate 301. The cover plate 305 completely covers the photovoltaic panel 5 and the installation groove. The cover plate 305 is fixed on the support plate 301 through a fixing component 4. Through the fixing component 4, it can be ensured that the cover plate 305 made of light-transmitting glass is stably installed above the photovoltaic panel 5, preventing displacement or falling off under the action of wind force or other external forces, and cooperating with the support plate 301 can provide additional physical protection, preventing external objects from directly contacting the photovoltaic panel 5, reducing the risk of damage. At the same time, the cover plate 305 made of light-transmitting glass can effectively block the direct contact of dust and dirt, reducing the dust accumulation on the surface of the photovoltaic panel 5, thereby improving the power generation efficiency.

[0036] The fixing component 4 can have various forms, such as bolt connection. To make the structure more reliable, preferably, multiple sets of fixing components 4 are arranged at intervals around the circumference of 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 pushing block 404, a fixing block 405, a limiting rod 407, a second spring 408, and a slider 409. The axis of the third threaded rod 402 is arranged along the thickness direction of the cover plate 305. A transmission chamber 306 is provided on the cover plate 305, and the third threaded rod 402 is rotatably installed in the transmission chamber 306; the second knob 401 is coaxially and fixedly installed at the upper end of the third threaded rod 402 and is located outside the transmission chamber 306; the threaded tube 403 is threadedly connected to the third threaded rod 402, and the pushing block 404 is fixed to the lower end of the threaded tube 403. The outer side of the threaded tube 403 forms a sliding fit with the second chute inside the transmission chamber 306 through the slider 409. The fixing block 405 is fixed to the lower surface of the cover plate 305. An expansion slot 406 is provided inside the fixing block 405. The expansion slot 406 is connected to the transmission chamber 306 through a transmission cavity. The lower end of the pushing block 404 passes through the transmission cavity. A plurality of expansion slots 406 are arranged at intervals around the circumference of the pushing block 404. A limiting rod 407 is slidably inserted into each expansion slot 406 correspondingly. The axial direction of the limiting rod 407 is perpendicular to the axis of the pushing block 404. The end of the limiting rod 407 close to the pushing block 404 cooperates with the lower end of the pushing block 404 to form a wedge mechanism, that is, the lower end of the pushing 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 pushing block 404 into a linear movement of the limiting rod 407 in the radial direction of the pushing block 404. A second spring 408 is sleeved on the limiting rod 407. There is a spring installation cavity in the expansion slot 406 that is adapted to the second spring 408. A spring limiting protrusion is fixedly provided on the outer side wall of the limiting rod 407 in the area where the spring installation cavity is located. The second spring 408 is installed between the end wall of the spring installation cavity far from the transmission cavity and the spring limiting protrusion; on the upper surface of the support plate 301, fixing grooves 307 corresponding to each fixing block 405 are provided. The fixing block 405 is clamped inside the fixing groove 307. A limiting groove 308 corresponding to each limiting rod 407 is provided on the inner side wall of the fixing groove 307. By rotating the third threaded rod 402, the pushing block 404 can be moved downward, driving the outer end of the limiting rod 407 to move out of the expansion slot 406 and making the outer end of the limiting rod 407 clamped inside the limiting groove 308. The outer end of the limiting rod 407 is the end far from the pushing block 404; when the pushing block 404 is moved upward by rotating the third threaded rod 402, the restoring elastic force of the second spring 408 can make the outer end of the limiting rod 407 move out of the limiting groove 308.During specific operation, first drive the third threaded rod 402 to rotate through the second knob 401, thereby driving the pushing block 404 to move upward, ensuring that the restoring elastic force of the second spring 408 can retract the outer end of the limiting rod 407 into the telescopic groove 406 first. At this time, the fixing block 405 can be normally clamped inside the fixing groove 307. Then, rotate the second knob 401 in the reverse direction to drive the pushing block 404 to move downward. The pushing block 404 drives the limiting rod 407 to move according to the principle of the wedge mechanism. The outer end of the limiting rod 407 moves outside the telescopic groove 406, and finally the outer end of the limiting rod 407 is clamped inside the limiting 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 clamped inside the limiting groove 308, a planar contact parallel to the axis of the pushing block 404 is formed between the inner end surface of the limiting rod 407 and the outer side surface of the pushing block 404, that is, the contact surface between the two is parallel to the axis of the pushing block 404. For details, please refer to... Figure 6 。

[0037] To make the structure simpler and more reliable, the limiting rods 407 are arranged at equal intervals circumferentially around the pushing block 404.

[0038] To make the structure simpler and more reliable, there are two sliding blocks 409 and second sliding grooves, and they are symmetrically arranged on both sides of the threaded tube 403.

[0039] Based on the above photovoltaic curtain wall component, the present invention also provides a photovoltaic curtain wall system, including a power storage module and a power conversion module. The power conversion module is used to convert the direct current generated by the photovoltaic panel 5 into alternating current, and the power storage module is used to store the converted electric energy.

[0040] The overall operation method of the present invention is as follows: First, place the support frame 1 at the designated position. Then, the staff place the photovoltaic panel 5 in the installation groove opened on the surface of the support plate 301. Then, the staff lap the cover plate 305 on the surface of the support plate 301 and make the fixing block 405 clamped in the corresponding fixing groove 307. Then, the staff turn the second knob 401 to drive the third threaded rod 402 to rotate. The third threaded rod 402 drives the threaded tube 403 to move, and the threaded tube 403 drives the pushing block 404 to move synchronously. Since the mating surfaces between the pushing block 404 and the limiting rods 407 are inclined surfaces, the pushing block 404 can push the limiting rods 407 to move during the movement. When one end of the limiting rod 407 is clamped in the limiting groove 308, the staff can stop turning the second knob 401 to complete the preliminary installation of the photovoltaic panel 5.

[0041] Then the staff installs the support frame 1 at the designated position. When the angle of the photovoltaic panel 5 needs to be adjusted, only need to turn the first knob 201 to drive 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 of it to move. The connecting rods 204 drive the moving block 205 to move. The moving block 205 drives the first support rod 206 fixed on its surface to move. Since the upper end of the first support rod 206 and the support plate 301 are slidably hinged, therefore, during the movement of the first support rod 206, while being able to adjust the angle of the photovoltaic panel 5, the two sides of the support frame 1 can be at the same height, improving the installation stability. At the same time, during the rotation of the first threaded rod 202, it can drive the first bevel gear 207 to rotate. The first bevel gear 207 drives the second bevel gear 210 to rotate, thereby driving the second threaded rod 209 to rotate synchronously, driving the second threaded cap 211 and the pointer 212 fixed on the side of the second threaded cap 211 to move synchronously. Furthermore, the adjustment data can be observed through the relative position of the pointer 212 and the scale 105, avoiding uneven energy output caused by inconsistent tilt angles of multiple photovoltaic curtain walls and improving the overall power generation efficiency.

[0042] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
