Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic technology field especially relates to a photovoltaic module and photovoltaic roof system. BACKGROUND

[0002] In the existing photovoltaic module installation technology, the combination mode of photovoltaic panel and support system has certain problems; the conventional installation process needs the operating personnel to first insert the bottom end of the photovoltaic module into the support, then gradually incline the module to the support to complete the fixing; this process has certain technical defects.

[0003] Because the photovoltaic module is heavy (the mass of a single conventional monocrystalline silicon module is more than 20 kg), it needs multiple people to operate cooperatively, the installation efficiency is limited and the labor intensity is high; and during the inclination process, the center of gravity of the module continuously deviates, the operating personnel need to continuously exert the reverse torque to maintain the balance, and there is the risk of corner damage caused by the module slipping.

[0004] Therefore, it is urgent to provide a photovoltaic module and photovoltaic roof system to solve the above problems. UTILITY MODEL CONTENT

[0005] The technical problem to be solved by the utility model is to overcome the defects of the prior art, and provide a photovoltaic module and photovoltaic roof system.

[0006] To solve the above technical problems, one technical scheme of the utility model is to provide a photovoltaic module, which comprises a plurality of stand columns installed on the top of a roof main body, a photovoltaic module main body placed on the top of the plurality of stand columns, a plurality of support rods fixedly connected to the top of the plurality of stand columns, an inclined frame fixedly connected to the top of the plurality of support rods, a support plate rotatably connected to the bottom of the frame, the bottom end of the module main body placed in the support plate, two extension rods rotatably connected to the bottom of the support plate on both sides, and two shafts II rotatably connected to the other end of the two extension rods.

[0007] The bottom of the frame is fixedly connected with two limiting mechanisms, the two shafts II are located in the two limiting mechanisms respectively, and a positioning mechanism is slidably connected in the two limiting mechanisms.

[0008] The utility model is further provided as follows: the bottom of the support plate is fixedly connected with an L-shaped plate, the module main body is located at the open end of the L-shaped plate, and the frame is located at the periphery of the module main body.

[0009] Through the above technical scheme, the L-shaped plate serves to support the bottom of the module main body, and in the process of inclining the module main body, the L-shaped plate abuts against the module main body, so that the problem of corner damage caused by the module main body slipping is avoided, time and labor are saved.

[0010] The present invention is further configured such that: both of the telescopic rods are divided into telescopic ends and are hollow inside; each of the two telescopic rods is connected to a spring, and the two ends of the spring are fixedly connected to the two ends of the telescopic rod respectively.

[0011] Through the above technical solution, the telescopic rod supports the main body of the component, while the spring pair buffers the main body of the component, preventing the main body of the component from making hard contact with the frame and causing damage to the main body of the component.

[0012] The present invention is further configured such that: the limiting mechanism includes two sliding rods respectively fixedly connected to both sides of the bottom of the frame, and the two shafts are respectively located in the two sliding rods.

[0013] Through the above technical solution, the limiting mechanism limits the position of shaft two. When the main body of the component needs to be installed, the column, support rod, and frame are first installed. Then, the support plate is deflected so that it contacts the main body of the component before the frame. The support plate deflects, causing one end of the telescopic rod to deflect upward, causing the entire telescopic rod to deflect and tilt, causing the other end of the telescopic rod to move, causing shaft two to slide within the sliding groove rod. The sliding groove rod limits and guides shaft two, and the fixing block fixes shaft two. The telescopic rod supports and positions the support plate. Then, the bottom end of the main body of the component is placed into the groove formed by the combination of the support plate and the L-shaped plate. The L-shaped plate limits the position of the main body of the component. At this time, the back of the main body of the component is aligned with the front of the support plate. When the components come into contact, the worker releases their grip, and the main body of the component presses down on the support plate under its own weight. At the same time, the telescopic rod contracts under pressure, and the spring is deformed by compression. The spring buffers the support plate, preventing damage to the main body of the component from hard contact, while also reducing the burden on the workers, saving time and effort. Then, the moving fixing block releases the positioning of the second shaft, allowing the second shaft to automatically return to its initial position along the sliding rod. At this point, the main body of the component deflects into the frame. Finally, the main body of the component is installed and fixed to the frame and support rod by windproof pressure strips, bolts, and other fasteners, completing the fixation of the main body of the component. No multiple people are required to operate, reducing installation costs, improving installation efficiency, reducing labor intensity, saving costs, and making it convenient, quick, simple, and practical.

[0014] The present invention is further configured such that: the positioning mechanism includes a plurality of fixed blocks slidably connected in two sliding rods, one end of each of the plurality of fixed blocks is inclined, and a second spring is connected between the plurality of fixed blocks and the two sliding rods respectively, and the two ends of the second spring are fixedly connected to the fixed blocks and the sliding rods respectively.

[0015] Through the above technical solution, the positioning mechanism positions shaft two. When shaft two moves downward within the sliding groove rod, it contacts the inclined surface of the fixed block and abuts against it, forcing the fixed block to move towards spring two. At this time, spring two is being compressed until shaft two moves away from the fixed block. Under the elastic force of spring two, the fixed block pops out. When shaft two wants to move in the opposite direction, it contacts the back of the fixed block, preventing it from moving in the opposite direction. In its natural state, the support plate deflects downward, the telescopic rod moves upward, and shaft two moves upward. At this time, shaft two abuts against the back of the fixed block, thus positioning the support plate. The advantage of multiple fixed blocks is that they are easy to adjust, making it more suitable for the installation angle of the main component.

[0016] The present invention is further configured such that: each of the bottom ends of the plurality of fixed blocks is fixedly connected to an L-shaped rod, the plurality of springs are respectively sleeved on the outside of the plurality of L-shaped rods, and the plurality of L-shaped rods are slidably connected to the sliding groove rod.

[0017] Through the above technical solution, the function of the L-shaped rod is to release the fixing block from the shaft two. When you want to unlock it, pull the L-shaped rod to move the fixing block towards the spring two, so that the fixing block no longer blocks the shaft two, thus unlocking the shaft two and then unlocking the support plate.

[0018] A photovoltaic roof system comprising the aforementioned photovoltaic modules, wherein a distribution box is installed at the rear end of the roof body, a sensor is installed on the top of the distribution box, and a controller electrically connected to the sensor is installed inside the distribution box.

[0019] Through the above technical solution, the function of the distribution box is to distribute power and protect the circuit, while the function of the sensors and controllers is to monitor power generation, temperature, and faults in real time.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model achieves a dual improvement in installation efficiency and protective performance through the coordinated operation of multiple mechanisms: the main body of the component is self-positioned by gravity through the linkage of the support plate and the telescopic rod, and the lever principle is used to reduce the burden of manual force application; the spring buffer absorbs the impact force of the component pressing and avoids damage from hard contact; the limiting mechanism and the inclined fixing block form a two-way positioning, which both constrains the sliding trajectory of the second shaft and realizes automatic locking.

[0022] 2. This utility model uses an L-shaped rod to unlock and then mechanically links to achieve quick release of the fixing block, so that the support plate reset and frame closure can be operated by a single person throughout the process; the overall structure uses the mechanical self-locking principle and elastic elements to significantly improve work efficiency while ensuring installation accuracy, and reduce the cost of multi-person collaboration and subsequent maintenance difficulty.

Detailed Implementation

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0033] Please see Figures 1-8 A photovoltaic module according to this embodiment includes multiple columns 2 installed on the top of the roof body 1. A photovoltaic module body 3 is placed on the top of the multiple columns 2. Multiple support rods 4 are fixedly connected to the top of the multiple columns 2. An inclined frame 5 is fixedly connected to the top of the multiple support rods 4. A support plate 6 is rotatably connected to the bottom of the frame 5. The bottom end of the module body 3 is placed in the support plate 6. Telescopic rods 7 are rotatably connected to both sides of the bottom of the support plate 6. The other end of each of the two telescopic rods 7 is rotatably connected to a shaft 8.

[0034] like Figures 2-7As shown in the figure, an L-shaped plate 11 is fixedly connected to the bottom front end of the support plate 6. The main body 3 of the component is located at the open end of the L-shaped plate 11, and the frame 5 is located around the periphery of the main body 3. The function of the L-shaped plate 11 is to support the bottom of the main body 3 and to hold the main body 3 in place during tilting, so as to prevent the main body 3 from continuously shifting its center of gravity and requiring the operator to continuously apply a reverse torque to maintain balance, thus avoiding the problem of the main body 3 slipping and being damaged by bumps and knocks. It saves time and effort. The two telescopic rods 7 are divided into two telescopic ends and are hollow inside. Springs 12 are connected inside the two telescopic rods 7. The two ends of the springs 12 are fixedly connected to the two ends of the telescopic rods 7, respectively. The function of the telescopic rods 7 is to support the main body 3 and to buffer the main body 3 through the springs 12, so as to prevent the main body 3 from making hard contact with the frame 5 and causing damage to the main body 3.

[0035] like Figures 2-5 As shown, two limiting mechanisms 9 are fixedly connected to the bottom of the frame 5. Two shafts 8 are located within the two limiting mechanisms 9. The limiting mechanism 9 includes two sliding rods 901 fixedly connected to both sides of the bottom of the frame 5. The two shafts 8 are located within the two sliding rods 901. The function of the limiting mechanism 9 is to limit the shafts 8. When the main body of the component 3 needs to be installed, the column 2, support rod 4, and frame 5 are installed first. Then, the support plate 6 is deflected so that the support plate 6 contacts the main body of the component 3 before the frame 5. The support plate 6 deflects, causing one end of the telescopic rod 7 to deflect upward, causing the entire telescopic rod 7 to deflect and tilt, causing the other end of the telescopic rod 7 to move, causing the shaft 8 to slide within the sliding rod 901. The sliding rod 901 limits and guides the shaft 8. The fixing block 1001 fixes the shaft 8. The telescopic rod 7 supports and positions the support plate 6. Then, the bottom end of the main body of the component 3 is placed into the support plate 6 and L. Within the groove formed by the combination of the molded plates 11, the L-shaped plate 11 limits the position of the main body 3 of the component. At this time, the back of the main body 3 of the component is in contact with the front end of the support plate 6. When the worker releases his hand, the main body 3 of the component presses down on the support plate 6 under its own weight. At the same time, the telescopic rod 7 is compressed and retracted, and the spring 12 is deformed by compression. The spring 12 cushions the support plate 6, preventing the main body 3 of the component from being damaged due to hard contact, while also reducing the burden on the workers, saving time and effort. Then, the moving fixing block 1001 releases the positioning of the shaft 2 8, allowing the shaft 2 8 to automatically return to its initial position along the sliding rod 901. At this time, the main body 3 of the component deflects into the frame 5. Then, the main body 3 of the component is installed and fixed on the frame 5 and the support rod 4 by windproof pressure strips, bolts and other fasteners, completing the fixation of the main body 3. No multiple people are required to operate, reducing installation costs, improving installation efficiency, reducing labor intensity, saving costs, and making it convenient, quick and easy to use.

[0036] like Figures 2-3As shown, each of the two limiting mechanisms 9 is slidably connected to a positioning mechanism 10. The positioning mechanism 10 includes multiple fixed blocks 1001 slidably connected within the two sliding rods 901. One end of each fixed block 1001 is inclined. A second spring 1002 is connected between each fixed block 1001 and the two sliding rods 901. Both ends of the second spring 1002 are fixedly connected to the fixed blocks 1001 and the sliding rods 901, respectively. The function of the positioning mechanism 10 is to position the shaft 8. When the shaft 8 moves downward within the sliding rods 901, it contacts the inclined surface of the fixed block 1001 and presses against it, forcing the fixed block 1001 to move downward. When spring 1002 moves in one direction, it is compressing spring 1002 until shaft 8 moves away from fixing block 1001. Under the elastic force of spring 1002, fixing block 1001 pops out. When shaft 8 wants to move in the opposite direction, shaft 8 will contact the back of fixing block 1001, preventing shaft 8 from moving in the opposite direction. In the natural state, support plate 6 deflects downward, telescopic rod 7 moves upward, and shaft 8 moves upward. At this time, shaft 8 abuts against the back of fixing block 1001, thus positioning support plate 6. The advantage of multiple fixing blocks 1001 is that they are easy to adjust, making it more suitable for the installation angle of component body 3.

[0037] like Figures 2-3 As shown, an L-shaped rod 1003 is fixedly connected to the bottom end of each of the multiple fixing blocks 1001. Multiple springs 1002 are respectively sleeved on the outside of the multiple L-shaped rods 1003. The multiple L-shaped rods 1003 are slidably connected to the sliding rod 901. The function of the L-shaped rods 1003 is to release the fixing blocks 1001 from fixing the shaft 8. When you want to unlock, pull the L-shaped rods 1003, which will drive the fixing blocks 1001 to move towards the springs 1002, so that the fixing blocks 1001 no longer block the shaft 8. In this way, the shaft 8 can be unlocked, and then the support plate 6 can be unlocked.

[0038] In use, this utility model achieves efficient installation through the synergistic effect of the inclined support plate 6 and the support structure. First, the column 2, support rod 4, and frame 5 are fixed to the roof body 1. The support plate 6 is deflected so that its front end can more easily contact the component body 3. At this time, the support plate 6 drives the telescopic rod 7 to tilt and drives the shaft 8 to slide along the sliding groove rod 901 at the bottom of the frame 5. During the movement, the shaft 8 presses against the inclined surface of the fixing block 1001 and compresses the spring 1002. When the bottom end of the component body 3 is embedded in the support plate 6 and the L-shaped plate 11, the installation is completed. After the limiting groove is closed, the main body 3 of the component is released so that it presses against the support plate 6 under the action of gravity. The spring 12 inside the telescopic rod 7 buffers the impact force. At the same time, the shaft 8 is temporarily positioned by the fixing block 1001 under the action of the spring 1002. When it is necessary to adjust the angle of the main body 3 of the component, the L-shaped rod 1003 is pulled to release the restriction of the fixing block 1001 on the shaft 8. The shaft 8 is reset along the sliding rod 901, which drives the support plate 6 to return to its original position. Finally, the component is fixed to the frame 5 by the windproof pressure strip and bolts, realizing quick installation and angle fine adjustment by a single person.

[0039] like Figures 1-8 As shown, based on the photovoltaic modules described in any of the above embodiments, this utility model embodiment also provides a photovoltaic roof system. A distribution box 13 is installed at the rear end of the roof body 1. A sensor 14 is installed on the top of the distribution box 13. A controller 15 electrically connected to the sensor 14 is installed inside the distribution box 13. The function of the distribution box 13 is to distribute power and protect the circuit. The function of the sensor 14 and the controller 15 is to monitor the power generation, temperature, and faults in real time.
