Description

Technical Field

[0001] This application relates to the field of solar panels, and more particularly to a photovoltaic solar roof panel. Background Art

[0002] Solar photovoltaic power generation is a new type of power generation technology that directly converts solar radiation energy into electrical energy by using the photovoltaic effect at the semiconductor interface. As a solar power generation component, a solar photovoltaic panel can receive sunlight and convert light energy into electrical energy and other energies. Due to its advantages such as environmental protection and renewable energy, it occupies an important position in energy consumption.

[0003] In related technologies, most solar photovoltaic panels are composed of a solar panel body and a frame. Since the solar panel body is mostly fixed on the frame, the frame will be fixed on the bracket through multiple bolts and pressing pieces during the installation process.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when the solar panel body is damaged, it is necessary to loosen multiple bolts to disassemble the entire frame and the solar panel body, which is time-consuming and laborious to operate; moreover, as a whole, the frame occupies a large space and is not convenient for transportation and storage. Summary of the Utility Model

[0005] In order to facilitate the quick disassembly of the frame and the solar panel body, this application provides a photovoltaic solar roof panel.

[0006] This application provides a photovoltaic solar roof panel, adopting the following technical solutions:

[0007] A photovoltaic solar roof panel includes a solar panel body, four frames arranged around the solar panel body, and a connecting component for connecting adjacent two frames. A slot is opened on the outer side of the frame. The connecting component includes an angle steel that abuts against the ends of adjacent two frames and two groups of plugging components arranged on the angle steel. The two groups of plugging components are respectively plugged and matched with the slots of adjacent two frames.

[0008] By adopting the above technical solutions, first place the four frames around the solar panel body respectively, insert the edge of the solar panel body into the groove of the frame, then place the angle steel at the connection of adjacent two frames, and make the plugging components plugged and matched with the slots at the corresponding positions on the frame to realize the detachable connection between the frame and the solar panel body. Compared with bolt connection, the plugging and matching method can achieve quick disassembly, and the space occupied by each frame is very small, which is convenient for transportation and storage.

[0009] Optionally, the plugging component includes an installation cylinder arranged at one end of the angle steel away from the frame, a plug rod slidably connected inside the installation cylinder, a mounting plate arranged on the outer side of the plug rod, and an elastic member arranged between the mounting plate and the installation cylinder. The plug rod slidably penetrates through the angle steel, and the plug rod is in plug-in fit with the slot.

[0010] By adopting the above technical solution, pull the plug rod outwards so that the end of the plug rod close to the solar panel body retracts into the angle steel. At this time, the elastic member is in a compressed state. After the angle steel is attached to the two frames, under the elastic force of the elastic member, the plug rod is inserted into the corresponding slot of the frame, thereby realizing the connection between the angle steel and the frame.

[0011] Optionally, blocking pieces are arranged on both sides of the angle steel, inner arc-shaped elastic blocks are arranged on the inner sides of the blocking pieces, and outer arc-shaped elastic blocks matched with the inner arc-shaped elastic blocks are arranged at the positions of the frame corresponding to the blocking pieces.

[0012] By adopting the above technical solution, when installing the angle steel, it is necessary to move the angle steel in the horizontal direction. After the two are attached, the inner arc-shaped elastic block and the outer arc-shaped elastic block can improve the stability between the angle steel and the frame and can play a role in initially positioning the angle steel.

[0013] Optionally, a positioning hole is formed at the position of the bottom of the angle steel corresponding to the plug rod, and a plug strip slidably arranged in the positioning hole is in plug-in fit with the plug rod.

[0014] By adopting the above technical solution, make the end of the plug rod close to the solar panel body retract into the angle steel and make the elastic member in a compressed state. The plug strip can be aligned with the positioning groove at the bottom of the plug rod. Push the plug strip upwards so that the plug strip is inserted into the positioning groove at the bottom of the plug rod, thereby positioning the plug rod.

[0015] Optionally, the cross section of the frame is in a groove shape, and a plurality of buffer strips are arranged on the upper and lower inner walls of the frame, and a gap is left between adjacent two of the buffer strips.

[0016] By adopting the above technical solution, it can play a buffering role between the solar panel body and the frame to reduce damage to the solar panel body caused by the hard frame.

[0017] Optionally, buffer long strips connected to the plurality of buffer strips are arranged on the upper and lower inner walls of the frame, and the buffer long strips are used to block the gaps between the buffer strips.

[0018] By adopting the above technical solution, the buffer long strip can be tightly pressed against and attached to the surface of the solar panel body, which can reduce the phenomenon that rainwater flows into the inside of the frame when it rains, thereby reducing the accumulation of rainwater inside the frame.

[0019] Optionally, water outlet holes are formed in the buffer strip with the lowest height, a water outlet channel communicating with the water outlet holes is formed in the buffer short strip, and a drain hole communicating with the water outlet channel is formed in the frame.

[0020] By adopting the above technical solution, rainwater can flow into the water outlet channel of the buffer short strip through the water outlet holes in the buffer strip and be discharged from the frame along the drain hole, improving the drainage performance.

[0021] Optionally, a guiding surface for guiding the water on the solar panel body to the outside of the frame is arranged on one side of the buffer strip away from the buffer short strip.

[0022] By adopting the above technical solution, the arc-shaped guiding surface can guide the rainwater on the solar panel body to the outside of the frame to reduce the water accumulation on the surface of the solar panel body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] The following further elaborates on this application in conjunction with the Figures 1 to 5 accompanying drawings.

[0033] The embodiment of this application discloses a photovoltaic solar roof panel. Referring to Figure 1 , the photovoltaic solar roof panel includes a solar panel body 1, four frames 2 and a connection assembly. The solar panel body 1 includes a battery unit, a front surface glass and a back plate. The battery unit is made of silicon material and is responsible for converting sunlight into electrical energy. The battery unit is encapsulated in one or more layers of encapsulation materials to protect them from environmental factors such as moisture, dust and ultraviolet rays. Common encapsulation materials include EVA (ethylene-vinyl acetate) and PVB (polyvinyl butyral). A layer of tempered glass is covered on the front surface of the solar panel, which not only provides physical protection but also allows light to penetrate into the battery unit. The back plate is the back material of the solar panel, usually made of plastic or composite materials, which plays a role in protecting the battery unit and insulation. The junction box is a component that connects the battery unit and the external circuit. It usually contains bypass diodes to protect the solar panel from damage caused by shadow occlusion. The connector is used to connect the circuit of the solar panel with the external circuit. They can be in the form of plugs or sockets to ensure the reliability of the electrical connection. Inside the solar panel, bypass diodes are used to prevent the battery unit from failing due to shadow or other reasons, thereby protecting the performance of the entire solar panel.

[0034] Referring to Figure 2 , the four frames 2 are located around the solar panel body 1. The vertical cross-section of the frame 2 is in the shape of a groove. The frame 2 is composed of a lower section, a middle section and an upper section formed integrally. The lower section and the middle section are perpendicular to each other, the middle section and the upper section are perpendicular to each other, and the lower section and the upper section are parallel to each other. Both ends of the frame 2 are provided with inclined surfaces, so that the top view of the frame 2 is an isosceles trapezoid. After installing the four frames 2 around the solar panel body 1, the edge of the solar panel body 1 can be inserted into the groove of the frame 2. At this time, the inclined surfaces of the adjacent ends of the two adjacent frames 2 can be fitted. The connection assembly is provided in four groups and is installed between two adjacent frames 2. The connection assembly can realize the detachable fixed connection between two adjacent frames 2.

[0035] The connecting component includes an angle steel 3 and two groups of plug-in components 4. The angle steel 3 is arranged in an L shape, and the two ends of the angle steel 3 are respectively abutted against two adjacent frames 2. The two groups of plug-in components 4 are respectively installed at the two ends of the angle steel 3. Slots 5 are opened at positions on the outer side of each frame 2 and close to the two ends, and the two groups of plug-in components 4 are respectively in plug-in fit with the slots 5 of the two adjacent frames 2.

[0036] When installing the frame 2, first place the four frames 2 around the solar panel body 1 respectively, so that the edge of the solar panel body 1 is inserted into the groove of the frame 2. Then place the angle steel 3 at the connection of two adjacent frames 2, and make the plug-in component 4 in plug-in fit with the slot 5 at the corresponding position on the frame 2, so as to realize the detachable connection between the frame 2 and the solar panel body 1. Compared with bolt connection, the plug-in fit method can realize quick disassembly, and the space occupied by each frame 2 is very small, which is convenient for transportation and storage.

[0037] Refer to Figure 2 and Figure 3 As shown in, the plug-in component 4 includes an installation cylinder 6, a plug rod 7, a mounting plate 8 and an elastic member 9. The installation cylinder 6 is fixedly installed on the side of the angle steel 3 away from the solar panel body 1. The plug rod 7 is slidably connected in the installation cylinder 6. The two ends of the plug rod 7 slide through and extend out of the installation cylinder 6. One end of the plug rod 7 close to the solar panel body 1 slides through the angle steel 3, and the plug rod 7 is in plug-in fit with the slot 5 on the frame 2. A holding part is installed at the end of the plug rod 7 away from the solar panel body 1. The mounting plate 8 is fixedly sleeved on the outer side of the plug rod 7, and the mounting plate 8 is slidably connected in the installation cylinder 6. The two ends of the elastic member 9 are respectively fixed to the mounting plate 8 and the inner wall of the installation cylinder 6. In this embodiment, the elastic member 9 is a spring.

[0038] Before placing the angle steel 3 at the connection of two adjacent frames 2, first pull the plug rod 7 outwards, so that one end of the plug rod 7 close to the solar panel body 1 retracts into the angle steel 3. At this time, the elastic member 9 is in a compressed state. After the angle steel 3 is attached to the two frames 2, under the elastic force of the elastic member 9, the plug rod 7 is inserted into the corresponding slot 5 of the frame 2, so as to realize the connection between the angle steel 3 and the frame 2.

[0039] Preferably, a positioning hole 10 is provided at the bottom of the angle steel 3 at a position corresponding to the insertion rod 7, a plug strip 11 is slidably connected in the positioning hole 10, a positioning groove 12 is provided at the bottom of the insertion rod 7, and the plug strip 11 can be plugged and matched with the positioning groove 12 at the bottom of the insertion rod 7. It should be noted that the insertion rod 7 is pulled outward, so that the end of the insertion rod 7 close to the solar panel body 1 is retracted into the angle steel 3, and the elastic member 9 is in a compressed state. At this time, the plug strip 11 can be aligned with the positioning groove 12 at the bottom of the insertion rod 7, and the insertion strip 11 is pushed upward to insert the insertion strip 11 into the positioning groove 12 at the bottom of the insertion rod 7, so as to position the insertion rod 7. After aligning the insertion rod 7 with the corresponding slot 5 of the frame 2, the plug strip 11 is pulled downward, and under the elastic force of the elastic member 9, the insertion rod 7 is inserted into the corresponding slot 5 of the frame 2, so as to facilitate the installation of the angle steel 3. In addition, since the elastic member 9 is in a compressed state, after the insertion strip 11 is inserted into the positioning groove 12 at the bottom of the insertion rod 7, the elastic member 9 has a tendency to push the insertion rod 7 outward to increase the friction between the insertion strip 11 and the positioning groove 12, so that the insertion strip 11 is not easily separated from the positioning groove 12 due to its own gravity.

[0040] Furthermore, both sides of the angle steel 3 are integrally connected with a blocking piece 13, an inner arc-shaped elastic block 14 is glued to the inner side of the blocking piece 13, and an outer arc-shaped elastic block 15 is glued to the outer side of the frame 2 at a position corresponding to the blocking piece 13, and the outer arc-shaped elastic block 15 cooperates with the inner arc-shaped elastic block 14. In this embodiment, the inner arc-shaped elastic block 14 and the outer arc-shaped elastic block 15 are both made of rubber material and have a certain elasticity.

[0041] Since the blocking piece 13 is provided, when installing the angle steel 3, the angle steel 3 needs to be moved in the horizontal direction to achieve the fit between the angle steel 3 and the frame 2. After the fit, the inner arc elastic block 14 and the outer arc elastic block 15 can improve the stability between the angle steel 3 and the frame 2, and can play an initial positioning effect on the angle steel 3, which is convenient for subsequent operations. In addition, in the process of moving the angle steel 3, since the inner arc elastic block 14 and the outer arc elastic block 15 are both elastic, and the inner arc elastic block 14 and the outer arc elastic block 15 are mostly staggered, the smooth movement of the angle steel 3 can be ensured.

[0042] Reference Figure 4, Preferably, a plurality of buffer strips 16 are adhesively bonded to the upper and lower inner walls of the frame 2 with glue, and a gap is left between two adjacent buffer strips 16. In this embodiment, the buffer strips 16 are made of graphene material. When connecting the frame 2 to the solar panel body 1, the solar panel body 1 can extrude the buffer strips 16 to achieve the smooth connection between the solar panel body 1 and the frame 2. Moreover, the graphene material has good toughness and can be bent, so that the buffer strips 16 can play a buffering role between the solar panel body 1 and the frame 2 to reduce damage to the solar panel body 1 caused by the rigid frame 2. In addition, the buffer strips 16 made of graphene material have high thermal conductivity.

[0043] Furthermore, buffer long strips 17 are adhesively bonded to the upper and lower inner walls of the frame 2 with glue. The buffer long strips 17 are connected to the plurality of buffer short strips 16. Compared with the buffer short strips 16, the buffer long strips 17 are closer to the outer side of the frame 2, so that the buffer long strips 17 can block the gaps between the buffer short strips 16. In this embodiment, the buffer long strips 17 are made of graphene material.

[0044] When the four frames 2 are installed around the solar panel body 1, the buffer long strips 17 can be tightly pressed against and fit the surface of the solar panel body 1, which can reduce the phenomenon of rainwater flowing into the inside of the frame 2 when it rains, thereby reducing the accumulation of rainwater inside the frame 2. Since the graphene material has good toughness and can be bent, the buffer long strips 17 can play a buffering role between the solar panel body 1 and the frame 2.

[0045] Preferably, a guiding surface 18 with an arc shape is arranged on the side of the buffer long strip 17 away from the buffer short strip 16. When rainwater flows to the surface of the buffer long strip 17, the arc-shaped guiding surface 18 can guide the rainwater on the solar panel body 1 to the outside of the frame 2 to reduce the accumulation of water on the surface of the solar panel body 1.

[0046] Refer to Figure 5 , Furthermore, since the solar panel body 1 is mostly inclined, there must be a frame 2 with the lowest height. Therefore, a water outlet hole 19 is provided on the buffer long strip 17 with the lowest height, a water outlet channel 20 is provided on the buffer short strip 16, and the water outlet channel 20 is communicated with the water outlet hole 19. A drain hole 21 is provided on the frame 2, and the drain hole 21 is communicated with the water outlet channel 20.

[0047] The rainwater that fails to flow away on the guiding surface 18 can flow into the water outlet channel 20 of the buffer short strip 16 through the water outlet hole 19 on the buffer long strip 17 and be discharged from the frame 2 along the drain hole 21, improving the drainage performance. In addition, since the graphene material also has the characteristic of corrosion resistance, it can reduce the corrosion caused by rainwater.

[0048] The implementation principle of a photovoltaic solar roof panel in an embodiment of this application is as follows: When installing the frame 2, first place the four frames 2 around the solar panel body 1 respectively, so that the edge of the solar panel body 1 is inserted into the groove of the frame 2. Then place the angle steel 3 at the connection of two adjacent frames 2. Pull the insertion rod 7 outwards, so that the end of the insertion rod 7 close to the solar panel body 1 retracts into the angle steel 3, and the elastic member 9 is in a compressed state. At this time, the insertion strip 11 can be aligned with the positioning groove 12 at the bottom of the insertion rod 7. By pushing the insertion strip 11 upwards, the insertion strip 11 is inserted into the positioning groove 12 at the bottom of the insertion rod 7, thereby positioning the insertion rod 7. After aligning the insertion rod 7 with the corresponding slot 5 of the frame 2, pull the insertion strip 11 downwards. Under the elastic force of the elastic member 9, the insertion rod 7 is inserted into the corresponding slot 5 of the frame 2 to realize the detachable connection between the frame 2 and the solar panel body 1.

[0049] The above are all preferred embodiments of this application.
