Description

Technical Field

[0001] This application relates to the field of photovoltaic energy storage technology, specifically to a photovoltaic module and an RTK fixed station antenna. Background Technology

[0002] RTK base station antennas are core components for achieving centimeter-level positioning in intelligent operational equipment such as lawnmowers and cleaning robots. Their main function is to receive satellite signals and perform real-time differential positioning with a mobile station, eliminating interference from atmospheric and ephemeris errors. Currently, RTK base station antennas primarily use three charging methods: wired DC power supply, solar-assisted power supply, and lithium battery pack power supply. In solar-assisted power supply applications, both the solar panel and the battery pack are fixed to a backplate bracket, which in turn is fixed to the antenna. Given the long-term outdoor operation characteristics of photovoltaic modules, the solar panel and backplate bracket often require sealing with a sealant, typically silicone, to protect the internal components from water and dust.

[0003] In the past, in the aforementioned photovoltaic modules, the sealing silicone was installed along the edge of the solar panel and the backsheet support. This caused the following problems: the silicone was prone to deformation and expansion when exposed to sunlight, which caused it to overflow from the installation gap between the edge of the solar panel and the backsheet support. This not only easily led to sealing failure, but in severe cases, it could also cause permanent deformation or even cracking of the support edge.

[0004] Based on the above, in the field of photovoltaic modules, how to prevent the outer sealing silicone from expanding and overflowing from the gaps at the edge of the bracket has become an urgent problem to be solved. Utility Model Content

[0030] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. The drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0031] refer to Figures 1 to 14 This specification provides a photovoltaic module 100, which aims to solve the problem that existing photovoltaic modules are prone to bulging and deformation on the surface of the photovoltaic panel 3 and / or backsheet due to the expansion of internal gas. It can not only provide venting protection for the backsheet frame 1, photovoltaic panel 3, sealant and other parts to eliminate bulging and deformation on the main board surface, but also provide targeted venting protection for the energy storage battery pack 4 to prevent the heat radiation generated by the photovoltaic panel 3 to the battery cells from causing the battery to enter a high-temperature protection state and prevent the energy storage battery pack 4 from bulging.

[0032] In this embodiment, the photovoltaic module 100 can be configured in various scenarios. For example, in one case, it can be configured on an RTK fixed station antenna as an auxiliary charging device for the antenna body 200. In another case, it can be configured on an outdoor support plane to supply power to small and medium-sized electrical equipment on that plane. The support plane is typically the ground. Furthermore, it can also be configured on various vehicle equipment as an auxiliary power supply device for vehicle-mounted electrical units. There are no restrictions on this.

[0033] like Figures 1 to 5 as well as Figure 8 As shown, the photovoltaic module 100 includes a backsheet frame 1, a photovoltaic panel 3, an energy storage battery pack 4, a first venting structure, and a second venting structure. The photovoltaic panel 3 is bonded to the front of the backsheet frame 1 using double-ring sealant. Here, the side of the backsheet frame 1 facing the photovoltaic panel 3 is defined as the front side, and the side opposite to the front side of the backsheet frame 1 is defined as the back side or rear side. Naturally, the portion of the backsheet frame 1 where the front side is located is the front part, and the portion where the rear side is located is the back or rear part. Figure 1As shown, the rear part of the backplate frame 1 is connected to the antenna body 200 of the RTK fixed station antenna, while the front part is bonded to the photovoltaic panel 3. The energy storage battery pack 4 is installed on the back of the backplate frame 1 and located within the inner circumference of the inner ring sealant 6. The double ring sealant includes an inner ring sealant 6 surrounding the energy storage battery pack 4 and an outer ring sealant 5 surrounding the inner ring sealant 6. The first venting structure is formed in the first area 7 surrounded by the photovoltaic panel 3, the backplate frame 1, and the double ring sealant to facilitate the discharge of the expanded gas in the area to the outside. The second venting structure is formed in the second area 8 surrounded by the photovoltaic panel 3, the backplate frame 1, the energy storage battery pack 4, and the inner ring sealant 6 to facilitate the discharge of the expanded gas in the area to the outside.

[0034] like Figure 5 and Figure 8 As shown, this embodiment uses a zoned venting method to simultaneously vent and protect the photovoltaic panel 3, backsheet frame 1, double-ring sealant, and energy storage battery pack 4. Specifically, the first venting structure is formed within the first region 7 surrounded by the photovoltaic panel 3, backsheet frame 1, and double-ring sealant. The first venting structure promptly vents the expanding gas in the first region 7, providing venting protection for the photovoltaic panel 3 and backsheet frame 1 in that region, preventing encapsulation delamination and sealing failure. The second venting structure promptly vents the expanding gas and chemically generated gas from the battery pack in the second region 8, providing venting protection for the photovoltaic panel 3 and backsheet frame 1 in that region, as well as targeted venting protection for the energy storage battery pack 4, preventing damage to the battery pack. The double-ring sealant structure prevents external moisture from penetrating into the inner cavity of the backsheet frame 1 and intruding into the internal components of the energy storage battery pack 4 and / or other photovoltaic modules 100, such as electrodes and wiring harnesses. It also prevents the internal high-temperature expansion gas from acting on the frame 11 of the backsheet frame 1, preventing thermal deformation of the frame 11. Through the synergistic effect of the first and second venting structures, bulging deformation of the photovoltaic panel 3 and / or backsheet frame 1 and / or energy storage battery pack 4 is effectively prevented, thereby improving the reliability of the photovoltaic module 100 during use.

[0035] Here, the first venting structure is formed within the first area enclosed by the photovoltaic panel 3, the backplate frame 1, and the double-ring sealant. This means that the first venting structure becomes part of the structure between the backplate frame 1, the photovoltaic panel 3, and the double-ring sealant, and can be naturally formed as the assembly or connection relationship of the backplate frame 1, the photovoltaic panel 3, and the double-ring sealant is established, without the need for an additional venting drive unit, such as a fan. Similarly, the second venting structure is formed within the second area 8 enclosed by the photovoltaic panel 3, the backplate frame 1, the energy storage battery pack 4, and the inner ring sealant 6. This means that the second venting structure can be naturally formed as the assembly or connection relationship or positional relationship of the backplate frame 1, the photovoltaic panel 3, the energy storage battery pack 4, and the double-ring sealant is established, without the need for an additional venting drive unit. It should be noted that the solenoid valve-type vent valve described below only has the ability to control the opening and closing of the venting channel and does not have the function or effect of driving venting.

[0036] The method of using the exhaust structure is not limited here; in other words, it can be used in a self-operated or passive manner. A self-operated method includes, for example, exhaust controlled by a solenoid valve, while a passive method includes, for example, exhaust through a waterproof and breathable membrane. There are no restrictions on either method.

[0037] Here, encapsulation delamination specifically refers to the phenomenon of separation or peeling at the bonding interface between two materials due to the difference in their coefficients of thermal expansion. In this embodiment, encapsulation delamination, in one case, refers to the phenomenon of separation or peeling between the photovoltaic panel 3 and the back sheet frame 1 at the sealant bonding position, and / or the phenomenon of separation or peeling between the photovoltaic panel 3 and the surface photoelectric element at the bonding position. This not only causes sealing failure, but also the infiltration of external gases into the first region 7 and / or the second region 8 will significantly increase the thermal stress or vapor pressure on the photovoltaic panel 3 and / or the back sheet frame 1, thereby causing bulging deformation.

[0038] Here, the outdoor use environment and installation location of the photovoltaic module 100 determine its need for waterproofing and lightweighting. Therefore, in this embodiment, the photovoltaic module 100 can be made of lightweight materials, typically plastic. Specifically, the photovoltaic panel 3 can be made of plastic base plate, and the photoelectric elements are arranged on the plastic base plate. The back panel frame 1 can also be made of plastic. In another way, the back panel frame 1 can also be made of plastic material or other lightweight materials.

[0039] like Figures 3 to 5 As shown, in one scenario, the photovoltaic module 100 includes a first rib component 12, which is disposed on the backsheet frame 1 and circumferentially distributed within the first region 7. Based on this, as... Figures 13 to 14 As shown, the first exhaust structure includes a first air guide gap 121 and a first exhaust channel. The first air guide gap 121 is formed between the first rib assembly 12 and the photovoltaic panel 3, and the first exhaust channel is formed on the back panel frame 1, connecting the first air guide gap 121 with the outside.

[0040] In one scenario, the expanding gas in the first region 7 can be guided to the first exhaust channel through the first gas guide gap 121 and discharged to the outside in a timely manner from the first exhaust channel, thereby preventing the expansion gas from accumulating in the first region 7 and causing local thermal stress to increase, which would cause the photovoltaic panel 3 and the back sheet frame 1 in that region to bulge.

[0041] The specific form of the first exhaust passage is not limited here. As an example, the first exhaust passage is defined by at least one exhaust pipe connected to the back plate frame 1, one end of which communicates with the outside and the other end with the first air guide gap 121. As another example, the first exhaust passage includes at least one first exhaust hole 74 formed on the back plate frame 1 and communicating with the outside, as described below.

[0042] In one scenario, a sealing element is disposed within the first exhaust passage. The sealing element is connected to the inner wall of the first exhaust passage via, for example, an elastic element. In its natural state, the sealing element blocks the first exhaust passage. When the gas pressure in the first region 7 rises to a set threshold, the sealing element overcomes the spring force by moving or deforming to open the first exhaust passage and allow gas to escape. When the gas pressure in the first region 7 drops to a normal level, the sealing element blocks the first exhaust passage again.

[0043] In one scenario, a breathing cover is provided on the first exhaust channel. The breathing cover seals and covers the channel outlet in its natural state. When the gas pressure in the first region 7 rises to a set threshold, the breathing cover opens the channel outlet to exhaust gas. When the gas pressure in the first region 7 drops to a normal level, the breathing cover seals and covers the channel outlet again.

[0044] In one scenario, a waterproof and breathable membrane is disposed within the first exhaust channel.

[0045] In this embodiment, the first exhaust channel includes at least one first exhaust hole 74 formed on the back plate frame 1 and communicating with the outside. The first exhaust hole 74 timely discharges the expanded gas and / or pressurized vapor in the first region 7 to the outside.

[0046] like Figure 5As shown, the first region 7 is an annular region. In one case, the first region 7 has only one first vent 74. Optionally, the first vent 74 can be formed at any position on the back plate frame 1 within the annular region.

[0047] like Figure 5 As shown, the first region 7 is an annular region. In one case, the photovoltaic panel 3 has an upper edge and a lower edge, and the first vent 74 is arranged in the first region 7 near the lower edge of the photovoltaic panel 3.

[0048] Specifically, the first region 7 is a loop-shaped region, where the photovoltaic module 100 is positioned as follows: Figure 1 In the working posture shown, the first region 7 is divided into an upper section near the upper edge of the photovoltaic panel 3, a lower section near the lower edge of the photovoltaic panel 3, and a middle section connecting the two. The upper and lower sections are arranged roughly parallel to the upper and lower edges of the photovoltaic panel 3. The first exhaust hole 74 is located in the lower section. This facilitates the discharge of internal moisture. On the other hand, since the density of hot air in the first region 7 is low, it will rise and accumulate near the upper section. At this time, the pressure in the lower section is relatively low, and external cold air can more easily enter the first region 7 from the first exhaust hole 74, thereby improving the efficiency of gas exchange in this region.

[0049] like Figure 5 As shown, in one scenario, the first region 7 has at least two first exhaust ports 74, one of which is located in the lower section and the other is located in the upper section. In this way, the hot air accumulated in the upper section can also be discharged to the outside through the other first exhaust port 74 in a timely manner, further improving the efficiency of gas exchange in the region.

[0050] In one scenario, the first vent 74 is positioned below the energy storage battery pack 4, which can mitigate the intrusion of liquid water and / or dust to some extent.

[0051] In one scenario, the first rib assembly 12 has at least one boss portion connected to a rib within the first rib assembly 12, and the first vent 74 penetrates the boss portion along a predetermined direction and communicates with the outside. Optionally, the predetermined direction is parallel to the rib protrusion direction.

[0052] In this embodiment, a first vent valve 741 is disposed inside the first vent hole 74, and the first vent valve 741 and the first vent hole 74 are sealed together.

[0053] Specifically, a first vent valve 741 is disposed within the first vent hole 74. The inner wall of the first vent hole 74 extends inward to form a flange. A sealing element, such as an O-ring, is disposed between the first vent valve 741 and the flange and / or the inner wall of the first vent hole 74. The first vent valve 741 achieves waterproofing and breathability while balancing the gas pressure difference between the first area 7 and the outside environment.

[0054] In one aspect, the first vent valve 741 is detachably connected to the first vent port 74, such as by means of a threaded connection to the first vent port 74. Alternatively, it may be connected to the first vent port 74 by means of a snap-fit ​​connection.

[0055] Taking the snap-fit ​​connection as an example, the first vent valve 741 has a pressing part and a snap-fit ​​part. The pressing part is for the user to press and operate. The first vent valve 741 is configured to respond to the pressing operation on the pressing part so that the snap-fit ​​part can be elastically snapped onto the inner wall of the first exhaust hole 74.

[0056] More specifically, the pressing part is disposed at one end of the first vent valve 741, and the snap-fit ​​part is disposed at the other end of the first vent valve 741. The snap-fit ​​part is an elastic snap-fit ​​part and has a tapered end face and abutting surface. The abutting surface is connected to the tapered end face and is configured to extend generally radially upward. The tapered end face allows the snap-fit ​​part to elastically pass through the inner hole of the flange portion. The abutting surface abuts against the inner side of the flange portion after the tapered end face passes through the inner hole of the flange portion. At this time, the main body of the first vent valve 741 abuts against the outer side of the flange portion, and the first vent valve 741 is installed and fixed.

[0057] In one aspect, the first vent valve 741 is configured to operate the valve chamber to open and close.

[0058] For example, the first vent valve 741 is an active miniature solenoid valve. The photovoltaic module 00 is equipped with a sensor to monitor the air pressure value inside the first region 7. When the monitored internal air pressure value reaches the threshold, the electromagnetic coil is energized to generate a magnetic field, which attracts the valve disc to displace and open the channel, allowing the expanded gas inside the first region 7 to be discharged. After the pressure is balanced, the power is cut off and reset, and the spring pushes the valve disc to reseal.

[0059] In another aspect, the valve cavity of the first vent valve 741 is provided with a hydrophobic microporous structure.

[0060] Specifically, the first vent valve 741 is a passive vent valve. The valve chamber of the first vent valve 741 is equipped with a microporous membrane. Water vapor and small molecule gases inside the first region 7 penetrate the microporous membrane channels under the influence of the internal and external pressure difference, while dry air from the outside diffuses in the opposite direction through the membrane pores, achieving internal and external pressure balance. Throughout the process, the hydrophobic properties of the microporous membrane prevent liquid water from passing through. This passive vent valve has no moving parts and relies on material properties to achieve opening and closing, enabling adaptive adjustment of internal and external air pressure.

[0061] In one aspect, such as Figures 3 to 6 , Figure 9 and Figure 13 As shown, the first air guide gap 121 is provided by the installation spacing reserved between the first rib component 12 and the photovoltaic panel 3. In this way, under the premise of realizing the exhaust protection of each associated component in the first region 7 of the photovoltaic module 100, there is no need to design or process an additional exhaust structure, thus simplifying the manufacturing process of the photovoltaic module 100.

[0062] In one aspect, the installation gap between the first rib assembly 12 and the photovoltaic panel 3 is small, resulting in poor flow capacity when directly used as the first air guide gap 121. Therefore, the first exhaust structure includes at least one ring of first air guide grooves 122. The first air guide grooves 122 are constructed on the first rib assembly 12 and arranged around the inner ring sealant 6. The first air guide grooves 122 are connected to the first exhaust channel. In this way, the expanding gas between the first air guide grooves 122 and the photovoltaic panel 3 can be freely guided and circulated within the first air guide grooves 122 and promptly discharged through the first exhaust channel. This also allows the expanding gas around the first air guide grooves 122 to be quickly guided and circulated through the first air guide gap 121 and promptly discharged through the first exhaust channel, thereby improving the exhaust efficiency within the first region 7 and reducing the probability of bulging of the panel and / or back panel.

[0063] In this embodiment, the internal ribs of the first rib component 12 divide the first region 7 into multiple independent first air chambers 1221. The first air guide gap 121 connects the multiple independent first air chambers 1221 sequentially along the ring upwards to guide the gas in each first air chamber 1221 to be discharged to the outside.

[0064] Furthermore, the first air guide gap 121 and the first air guide groove 122 are connected together along the ring upward to the plurality of independent first air chambers 1221, so as to guide the gas in each first air chamber 1221 to be discharged to the outside.

[0065] It should be understood that the "independent" first air chamber 1221 here refers to its structural independence, not that the first air chambers 1221 are not interconnected. In fact, in this embodiment, the first air chambers 1221 can be connected by the first air guide gap 121. The configuration of the first air guide groove 122 increases the flow of gas between the first rib assembly 12 at each position along the specified circumferential path. Therefore, the expanding gas in each first air chamber 1221 corresponding to the first air guide gap 121 at each position on the circumferential path can flow into the first air guide groove 122 in a timely manner through the first air guide gap 121 and then be guided and discharged to the outside.

[0066] It should be understood that the first air guide groove 122 sequentially connects to a plurality of independent first air chambers 1221 along the circumferential direction, and does not only refer to each of the first air chambers 1221 that the first air guide groove 122 passes through along the prescribed circumferential path, but includes all the first air chambers 1221 covered by the first air guide gaps 121 at each position on the circumferential path.

[0067] It should be understood that the connection between the first air guide groove 122 and the first exhaust channel is not equivalent to the first air guide groove 122 being in communication with the first exhaust channel. In one case, the connection includes a structural connection, such as the input end of the first exhaust channel penetrating into the inner cavity of the first air guide groove 122 to achieve the connection between the two. Obviously, the connection between the first air guide groove 122 and the first exhaust channel can naturally achieve the communication between the two, but the reverse is not necessarily true. Specifically, the first air guide groove 122 penetrates the boss portion and the first exhaust hole 74 passes through the first air guide groove 122 to achieve the connection between the two.

[0068] In one aspect, the first rib assembly 12 is configured such that internal ribs are distributed circumferentially within the first region 7. The first rib assembly 12 has multiple rib junctions, and the first air guide groove 122 is configured to pass through as many rib junctions of the first rib assembly 12 as possible to minimize the impact of the groove on the ribs. Optionally, the first air guide groove 122 is positioned at the center of the radial span of the first region 7.

[0069] like Figures 3 to 5 As shown, in one scenario, the photovoltaic module 100 includes a second rib component 13, which is disposed on the backsheet frame and circumferentially distributed within a second region 8 between the inner sealant 6 and the energy storage battery pack 4. Based on this, as... Figures 13 to 14As shown, the second exhaust structure includes a second air guide gap 131 and a second exhaust channel. The second air guide gap 131 is formed between the second rib assembly 13 and the photovoltaic panel 3 and between the energy storage battery pack 4 and the photovoltaic panel 3. The second exhaust channel is formed on the energy storage battery pack 4 and connects the second air guide gap 131 with the outside.

[0070] In one scenario, the expanding gas in the second region 8 can be guided to the second exhaust channel through the second gas guide gap 131 and discharged to the outside in a timely manner from the second exhaust channel, thereby preventing the expanding gas from accumulating in the second region 8, which would lead to an increase in local thermal stress and cause bulging on the surface of the photovoltaic panel 3 and / or backsheet frame 1 and / or energy storage battery pack 4 in that region.

[0071] It should be noted that the second air guide gap 131 is at least divided into two parts: the part formed between the second rib assembly 13 and the photovoltaic panel 3, as described below as the first air guide area, and the part formed between the energy storage battery pack 4 and the photovoltaic panel 3, as described below as the second air guide area. The former is mainly used to guide and discharge the expansion gas generated between the photovoltaic panel 3 and the back sheet frame 1 in the second area 8, preventing the surface of the photovoltaic panel 3 and the back sheet frame 1 from bulging. The latter is mainly used to guide and discharge the expansion gas generated between the energy storage battery pack 4 and the photovoltaic panel 3, preventing the heat generated between the two from radiating to the battery cell through the wall of the energy storage battery pack 4, causing the battery to trigger a high-temperature protection state, and also preventing the surface of the energy storage battery pack 4 from bulging and deforming.

[0072] It should be noted that the specific form of the second exhaust channel is not limited here. As an example, the second exhaust channel is defined by at least one exhaust pipe connected to the energy storage battery pack 4, with one end of the exhaust pipe communicating with the outside and the other end communicating with the second air guide gap 131. As another example, the second exhaust channel is jointly defined by at least one vent hole 84, the inner cavity of the energy storage battery pack 4, and at least one second exhaust hole 421, as described below, which will not be elaborated here.

[0073] like Figure 5 , Figure 10 As shown above, in one scenario, the second exhaust channel includes at least one vent hole 84 and at least one second exhaust hole 421. The vent hole 84 connects the second air guide gap 131 with the inner cavity of the energy storage battery pack 4, and the second exhaust hole 421 is formed on the energy storage battery pack 4, connecting the inner cavity of the energy storage battery pack 4 with the outside.

[0074] Here, as a known means, the inner cavity of the energy storage battery pack 4 has an installation gap, which can serve as a connecting air passage connecting the second exhaust port 421 and the vent 84. That is, the expanding gas in the second air guide gap 131 can be discharged to the outside through the second exhaust passage formed by the vent 84, the installation gap in the inner cavity of the energy storage battery pack 4, and the second exhaust port 421. At the same time, the chemical gas generated by the cells inside the energy storage battery pack 4 can also be discharged to the outside through the second exhaust port 421, thereby preventing the energy storage battery pack 4, the photovoltaic panel 3, and the back plate frame 1 from bulging and deforming, as well as the damage to the cells inside the energy storage battery pack 4.

[0075] In one embodiment, the cell assembly 44 includes a cell support and individual individual cells mounted on the cell support. In another embodiment, the mounting gap is formed between the cell assembly 44 and the inner wall of the energy storage battery pack 4 and / or between the individual individual cells within the cell assembly 44.

[0076] It should be noted that, in this embodiment, the intended technical objective is to quickly and promptly discharge the expanding gas within the second gas guide gap 131 into the second region 8, preventing the contact parts from bulging and deforming. The discharge of the expanding gas through the inner cavity of the energy storage battery pack 4 to the outside accelerates the rate of gas exchange between the inside and outside, maintaining temperature and pressure balance, and does not significantly increase the temperature inside the energy storage battery pack 4.

[0077] In one scenario, a second vent valve 4211 is disposed within the second vent port 421, and the second vent valve 4211 is in a sealing fit with the second vent port 421. The nature of the second vent valve 4211 may be similar to that of the first vent valve 741, and the aforementioned configuration and application of the first vent valve 741 in various scenarios can also be applied to the second vent valve 4211, which will not be elaborated here.

[0078] In one embodiment, the energy storage battery pack 4 has a complete, non-removable enclosed housing, which defines a cavity 43 containing a cell assembly 44, and at least one vent 84 and at least one second vent 421 are formed on the enclosed housing.

[0079] In one embodiment, the energy storage battery pack 4 includes a base shell 41, a rear cover 42, and a cell assembly 44. The base shell 41 is integrally formed on the back plate frame 1, and the rear cover 42 is sealed and installed on the base shell 41. The rear cover 42 and the base shell 41 define an inner cavity of the energy storage battery pack 4, namely a housing cavity 43. The cell assembly 44 is fitted into the inner cavity of the energy storage battery pack 4. The vent hole is formed on the base shell 41, and the second vent hole 421 is formed on the rear cover 42.

[0080] refer to Figure 9 , Figure 10 As shown, in one scenario, a positioning hole 414 is formed on the base shell 41, and a positioning post 441 is provided on the cell assembly 44. The positioning post 441 is connected to the positioning hole 414, and a vent hole 84 is formed between the positioning post 441 and the positioning hole 414.

[0081] In this embodiment, the ventilation hole 84 is formed between the positioning post 441 and the positioning hole 414. In this way, there is no need to open holes in other parts of the base shell 41, which minimizes the weakening of the structural strength and rigidity of the back plate frame 1 and reduces the probability of bulging.

[0082] In one scenario, a notch is formed on the positioning post 441 and / or the positioning hole 414, and the vent hole 84 includes a single notch, one end of which communicates with the inner cavity of the energy storage battery pack 4 and the other end of which communicates with the second air guide gap 131. Alternatively, the vent hole 84 may include two notches that are at least partially opposite each other in the radial direction, one end of which communicates with the inner cavity of the energy storage battery pack 4 and the other end of which communicates with the second air guide gap 131. This can increase the flow rate, but the strength of the corresponding positioning structure is weakened to some extent.

[0083] In one configuration, the positioning post 441 is constructed with a cross-shaped cross section, and the vent hole 84 is formed on the positioning post 441. Clearly, the positioning hole 414 is a necessary feature for positioning the aforementioned components. Here, the vent hole 84 is entirely formed on the positioning post 441, eliminating the need for secondary processing of the positioning hole 414 and preventing any weakening of the structural strength and rigidity of the base shell 41 or the back plate frame 1 at that location. Alternatively, the positioning post 441 can also be constructed with a gear-shaped cross section or a segmental cross section; no limitation is imposed here.

[0084] like Figure 5 As shown, in this embodiment, the second rib assembly 13 is located between the inner ring sealant 6 and the energy storage battery pack 4 and separates multiple second air chambers 1331 within the second region 8. The second air guide gap 131 includes a first air guide area and a second air guide area. The first air guide area is formed between the second rib assembly 13 and the photovoltaic panel 3 to connect the multiple second air chambers 1331. The second air guide area is formed between the energy storage battery pack 4 and the photovoltaic panel 3. The second air guide area connects the second exhaust channel and the first air guide area.

[0085] In this embodiment, the base shell 41 has a raised portion that protrudes from the front of the back plate frame 1 toward the photovoltaic panel 3. The raised portion has an annular side edge 412. The top of the raised portion defines a positioning surface. The side edge 412 is arranged around the positioning surface and protrudes from the positioning surface toward the photovoltaic panel 3. The positioning hole 414 is formed on the positioning surface. The photovoltaic panel 3 abuts against the side edge 412. The second air guiding area is formed between the inner wall of the side edge 412, the positioning surface, and the photovoltaic panel 3. The second rib assembly 13 is located between the raised portion and the inner ring sealant 6. The side edge 412 has a plurality of notches 413 for connecting the first air guiding area and the second air guiding area.

[0086] like Figure 14 As shown, in one scenario, to further improve gas flow capacity, the second exhaust configuration includes at least one ring of second air guide grooves 132, which are arranged upward along the ring on the second rib assembly 13.

[0087] In one embodiment, the second exhaust channel further includes at least one third exhaust hole formed on the back plate frame 1. The third exhaust hole is located within the first air guiding zone, and a third vent valve is disposed within the third exhaust hole. The second air guiding groove 132 is connected to the third exhaust hole. Through the cooperation of the second air guiding groove 132 and the third exhaust hole, separate exhaust protection for the first air guiding zone is achieved, reducing the exhaust pressure in the second air guiding zone and improving the overall exhaust efficiency within the second region 8.

[0088] In one scenario, the photovoltaic panel 3 has a central region that is bonded to the back panel frame 1 by at least one adhesive strip 9 located within the second region 8.

[0089] Specifically, the photovoltaic panel 3 is bonded to the energy storage battery pack 4 by at least one adhesive strip 9. The second venting gap 131 includes a venting distance 85 located between adjacent adhesive strips 9 and / or between adjacent adhesive strips 9 and the wall of the energy storage battery pack 4. The venting distance 85 is located within the second venting area and communicates with the second exhaust channel. In this way, while bonding and fixing the central area of ​​the photovoltaic panel 3 and the energy storage battery pack 4, the venting distance 85 is constructed to release the expanding gas generated between the adhesive strips 9 and discharge it to the outside through the second exhaust channel.

[0090] Specifically, the photovoltaic panel 3 is bonded to the positioning surface by multiple adhesive strips 9. The second air guide gap 131 includes an air guide distance 85 located between adjacent adhesive strips 9 and / or between adjacent adhesive strips 9 and the side edge portion 412. In this embodiment, the panel is bonded to the positioning surface by three adhesive strips 9, which are arranged in parallel relative to each other and spaced apart.

[0091] Here, the air guide spacing 85 is located within the second air guide zone and is connected to the second air guide zone. Optionally, the vent hole 84 is located within the air guide spacing 85.

[0092] like Figure 4 , Figures 5 to 6 As shown, in this embodiment, the back panel frame has a first adhesive groove 14 with an upper opening. The outer ring sealant 5 is filled in the first adhesive groove 14 and at least partially exposed through the upper opening to the first adhesive groove 14 and bonded to the photovoltaic panel 3.

[0093] In this embodiment, the back panel frame has a second adhesive groove 15, the second adhesive groove 15 has an upper opening, the inner ring sealant 6 is filled in the first adhesive groove 14 and at least partially exposed through the upper opening of the first adhesive groove 14 and is bonded to the photovoltaic panel 3.

[0094] In one embodiment, the first rib assembly 12 is configured such that the internal ribs are distributed circumferentially between the first adhesive groove 14 and the second adhesive groove 15.

[0095] In one embodiment, the back panel frame 1 includes a frame 11, and the outer ring sealant 5 is the first sealant applied radially from the outside to the inside between the photovoltaic panel 3 and the back panel frame 1, i.e., the edge sealant. When the outer ring sealant 5 is an edge sealant, the first venting structure can promptly discharge the expanding hot air in the first region 7 to the outside, preventing the hot air from corroding the frame 11 and causing thermal deformation of the frame 11. At the same time, the edge sealant prevents external moisture from penetrating into the first region 7 and being converted into hot vapor that acts on the photovoltaic panel 3 and the back panel frame 1, causing bulging deformation on their surfaces.

[0096] In one embodiment, the back panel frame 1 includes a frame 11, and a gap is left between the outer ring sealant 5 and the frame 11. This prevents the edge sealant from expanding due to heat and overflowing from the installation gap between the photovoltaic panel 3 and the back panel frame 1.

[0097] In one embodiment, the back panel frame 1 has an annular drainage groove 16 located between the frame 11 and the outer ring sealant 5. The drainage groove 16 has a drainage hole 167 for draining moisture to the outside. Here, the drainage hole 167 can also serve as a vent, allowing the expanding gas in the drainage groove to be discharged to the outside in a timely manner, preventing thermal deformation of the frame 11 and preventing the outer ring sealant 5 from failing.

[0098] In this embodiment, a photovoltaic module 100 is also provided, showing the situation where the photovoltaic panel 3 and the back sheet frame 1 are bonded using a single-ring sealant. Specifically, the photovoltaic module 100 includes a back sheet frame 1, a photovoltaic panel 3, an energy storage battery pack 4, and a venting structure. The photovoltaic panel 3 is bonded to the back sheet frame 1 by a single-ring sealant. The energy storage battery pack 4 is installed on the back sheet frame 1 and located within the inner circumference of the single-ring sealant. The venting structure is formed in the area enclosed by the photovoltaic panel 3, the back sheet frame 1, the energy storage battery pack 4, and the inner ring sealant 6 to facilitate the discharge of expansion gas in the area to the outside.

[0099] In this embodiment, a photovoltaic module 100 is also provided, illustrating the case where the photovoltaic panel 3 and the backsheet frame 1 are bonded using at least two layers of sealant, or the case where three or more layers of sealant are used. The photovoltaic module 100 specifically includes a backsheet frame 1, a photovoltaic panel 3, an energy storage battery pack 4, and a first venting structure and a second venting structure. The photovoltaic panel 3 is bonded to the backsheet frame 1 by at least two layers of sealant, which are arranged radially from the inside out. In one case, the at least two layers of sealant are arranged concentrically. The energy storage battery pack 4 is installed on the back of the backsheet frame 1 and located within the inner circumference of the innermost layer of sealant. The first venting structure is formed in the area enclosed by the photovoltaic panel 3, the backsheet frame 1, and any two adjacent layers of sealant to facilitate the discharge of expansion gas in the area to the outside. The second venting structure is formed in the area enclosed by the photovoltaic panel 3, the backsheet frame 1, the energy storage battery pack 4, and the innermost layer of sealant to facilitate the discharge of expansion gas in the area to the outside.

[0100] Whether the photovoltaic panel 3 and the backsheet frame 1 are bonded with a single ring of sealant or with at least two rings of sealant, the concept of the venting structure in this embodiment is utilized. The venting structure is a natural structure formed within the first region 7 or the second region 8. It can be formed naturally with the assembly, connection, or establishment of the positional relationship of the backsheet frame 1, photovoltaic panel 3, energy storage battery pack 4, and sealant, without the need for an additional venting drive unit. All of the above situations should be included within the protection scope covered by this embodiment.

[0101] In summary, this embodiment can simultaneously provide ventilation protection for the photovoltaic panel 3, backsheet frame 1, double-ring sealant, and energy storage battery pack 4 by using a zoned ventilation method, preventing bulging on the surfaces of the photovoltaic panel 3, backsheet frame 1, and energy storage battery pack 4, as well as damage to the energy storage battery pack 4.

[0102] Optionally, in the photovoltaic module 100, the backsheet frame 1 is an integrally molded component to improve the overall structural strength of the backsheet frame 1.

[0103] Optionally, the photovoltaic panel 3 is made of a plastic substrate, and the photovoltaic elements, including the solar cells, are mounted on the plastic substrate. Optionally, the back panel frame 1 is made of plastic to meet the lightweight requirements of the photovoltaic module 100 as much as possible.

[0104] like Figure 1 As shown, in this embodiment, an RTK fixed station antenna is also proposed, including an antenna body 200 and the aforementioned photovoltaic module 100. The photovoltaic module 100 is connected to the antenna body 200 to provide power to the antenna body 200.

[0105] like Figure 1 , Figures 3 to 5 As shown, this embodiment provides a photovoltaic module 100, which aims to solve the problem that the edge sealant of the photovoltaic module 100 is prone to expansion and overflow when exposed to sunlight in the prior art. It can not only prevent the edge sealant from expanding and overflowing from the edge gaps, but also effectively prevent the edge sealant from failing at high temperatures.

[0106] The following description, in conjunction with the accompanying drawings, details how the solution provided in this embodiment addresses the aforementioned problems.

[0107] like Figure 1 , Figures 3 to 5 As shown, in this embodiment, the photovoltaic module 100 includes a backsheet frame 1 and a photovoltaic panel 3. The backsheet frame 1 has a frame 11. The photovoltaic panel 3 is bonded to the backsheet frame 1 by a ring of edge sealant and is placed inside the frame 11. The edge sealant is the first layer of sealant between the photovoltaic panel 3 and the backsheet frame 1 in a radial direction from the outside to the inside. A gap is left between the edge sealant and the frame 11 to prevent the edge sealant from expanding and overflowing from the gap between the frame 11 and the photovoltaic panel 3.

[0108] In existing photovoltaic modules, edge sealant is typically bonded and fixed along the seam between the frame and the backsheet. When the photovoltaic module is in operation, sunlight shines on the frame, causing a large amount of heat to accumulate at the edges of the frame and backsheet, which is then conducted to the sealant. This can easily cause some sealants, such as silicone, to expand due to high temperatures and overflow from the seam. In this embodiment, by leaving a gap between the edge sealant and the frame 11, on the one hand, the edge sealant cannot overflow from the seam between the frame 11 and the photovoltaic panel 3 due to deformation and expansion, thus preventing frame deformation; on the other hand, it avoids direct contact between the edge sealant and the heat-accumulated frame, thereby preventing the edge sealant from failing due to high temperatures caused by absorbing a large amount of heat. Figure 3 and Figure 5 This illustrates a scenario where the outer ring sealant 5 is used as an edge sealant.

[0109] To further limit the deformation and expansion of the edge sealant, the back panel frame 1 has a first sealant groove 14 with an upper opening. The edge sealant is filled in the first sealant groove 14 and at least partially exposed through the upper opening to bond with the photovoltaic panel 3. The first sealant groove 14 restricts the position of the edge sealant, further preventing it from overflowing from the gap between the frame 11 and the photovoltaic panel 3.

[0110] like Figure 4 , Figure 5 As shown, in one scenario, a drainage groove 16 is formed between the back panel frame 1 and the photovoltaic panel 3, and the drainage groove 16 is located within the gap between the edge sealant and the frame 11. Here, the drainage groove 16 can be configured in various shapes. As an example, the drainage groove 16 is configured as a ring. As another example, the back panel frame 1 is configured as a rectangular frame, and the drainage groove 16 is configured as a U-shaped groove surrounding the edge sealant on three sides. Specifically, as previously described, the photovoltaic panel 3 has an upper edge, a lower edge, and a left edge and a right edge connecting the upper and lower edges. The drainage groove 16 includes a left groove between the left edge and the outer ring of the edge sealant, a right groove between the right edge and the outer ring of the edge sealant, and a lower groove between the lower edge and the outer ring of the edge sealant. Figure 1 As shown, the photovoltaic panel 3 is typically tilted during operation. Due to gravity, moisture on the photovoltaic panel 3 is unlikely to penetrate the photovoltaic module 100 from the upper edge seam. Therefore, the drainage groove 16 surrounding the edge sealant on three sides can solve most of the edge seam seepage problem. Alternatively, as an example, the drainage groove 16 can be constructed as a straight line. Optionally, the drainage groove 16 is located between the lower edge of the frame 11 and the outer ring of the edge sealant, only addressing the most serious problem of water seepage and accumulation at the lower edge seam.

[0111] In one configuration, an annular drainage groove 16 is formed between the backplate frame 1 and the photovoltaic panel 3, and the edge sealant is radially separated from the frame 11 by the drainage groove 16. This separation prevents the edge sealant from expanding and overflowing, reducing the likelihood of high-temperature sealant failure. Furthermore, it prevents water seepage and long-term water accumulation in the seams or installation gaps between the edge sealant and the frame, thus preventing sealant erosion and delamination.

[0112] like Figure 4 As shown, in one scenario, the surface of the backplate frame 1 protrudes upward to form an annular inner flange 141 and an outer flange 142. The first adhesive groove 14 is formed by the inner flange 141, the outer flange 142, and the backplate frame 1 between them. The inner flange 141 and the outer flange 142 together restrict the radial position of the edge sealant.

[0113] like Figure 4 As shown, in this embodiment, the back panel frame 1 has a support rib 143. The support rib 143 is radially connected to the inner baffle 141 and the outer baffle 142 respectively. The first glue groove 14 is formed by the inner baffle 141, the outer baffle 142 and the support rib 143. The support rib 143 can increase the structural support strength of the first glue groove 14, so that the first glue groove 14 can withstand the expansion force generated by the sealant for a long time without structural deformation.

[0114] In one scenario, the interior of the support rib 143 has multiple rib gaps, and the bottom of the edge sealant contacts the support rib 143. The bottom rib gaps can provide a certain space, allowing the sealant to release expansion deformation to a certain extent, thereby preventing the sealant from overflowing from the first adhesive groove 14.

[0115] like Figures 3 to 6 As shown, in one embodiment, the frame 11 has a snap fastener 111 that is operably pressed against the upper surface of the photovoltaic panel 3 so that the photovoltaic panel 3 is pressed against the edge sealant.

[0116] With the construction of the snap fastener 111, after the photovoltaic panel 3 is installed on the back panel frame 1, the snap fastener 111 presses against the upper surface of the photovoltaic panel 3, thereby pressing the photovoltaic panel 3 against the edge sealant. The edge sealant is confined within the first adhesive groove 14, further preventing the edge sealant from expanding and deforming due to heat, making the positioning of the edge sealant more reliable.

[0117] In one embodiment, the snap fastener 111 is a rotating snap fastener 111 rotatably connected to the frame 11 via a hinge or pivot. In another embodiment, the pivot may be configured with a torsion spring. The rotating snap fastener 111 is configured to rotate between a first angular position and a second angular position. The torsion spring is configured such that when the rotating snap fastener 111 is in the first angular position, it presses against the photovoltaic panel 3, and when the rotating snap fastener 111 is in the second angular position, it releases the photovoltaic panel 3 and allows the photovoltaic panel 3 to be removed from inside the frame 11.

[0118] like Figure 4 and Figure 6 As shown, in one scenario, the snap fastener 111 is formed on the frame 11, and the snap fastener 111 is operably pressed against the upper surface of the photovoltaic panel 3 by elastic deformation.

[0119] In this embodiment, the frame 11 defines an installation opening, through which the photovoltaic panel 3 is assembled onto the back panel frame 1. The snap-fit ​​part 111 is configured as an elastic strip extending laterally along the frame 11. The snap-fit ​​part 111 has a beveled portion on its front side and a pressing portion on its rear side. When the photovoltaic panel 3 is assembled onto the back panel frame 1 from the installation opening, the photovoltaic panel 3 elastically presses the snap-fit ​​part 111 through the beveled portion, causing it to deform and allowing the photovoltaic panel to be embedded into the frame 11. After the photovoltaic panel 3 is assembled, the pressing portion abuts against the photovoltaic panel 3.

[0120] In one configuration, the pressing portion is configured to be elastically deformed radially as the photovoltaic panel 3 moves toward the mounting opening, thereby avoiding the photovoltaic panel 3 until it can be removed from the frame 11. In another configuration, this elastic deformation may include only the elastic deformation of the snap fastener 111, or it may include both the elastic deformation of the snap fastener 111 and the elastic deformation of the frame 11.

[0121] like Figure 4 As shown, in one embodiment, the drainage channel 16 includes drainage holes 167 for draining water to the outside. These drainage holes 167 are formed on the frame 11 and spaced apart below the snap-fit ​​portion 111 along the snap-fit ​​direction. This reduces the structural rigidity of the frame 11 around the snap-fit ​​portion 111, making the elastic deformation of the snap-fit ​​portion 111 easier and facilitating the rapid assembly and disassembly of the photovoltaic panel 3.

[0122] In one scenario, the snap fastener 111 can be operably pressed against the upper surface of the photovoltaic panel 3 while the photovoltaic panel 3 is being assembled onto the back panel frame 1. This eliminates the need to first assemble the photovoltaic panel 3 and the back panel frame 1 and then press the snap fastener 111 against the photovoltaic panel 3, allowing the two processes to be performed simultaneously and improving the assembly efficiency of the photovoltaic panel 3.

[0123] In one embodiment, a plurality of snap-fit ​​portions 111 are formed on the inner wall of the frame 11, the frame 11 being a rectangular frame, and the plurality of snap-fit ​​portions 111 including two opposing snap-fit ​​portions 111, which are respectively disposed on two sides of the frame 11. In another embodiment, each side of the frame 11 has one or more snap-fit ​​portions 111 to ensure that the photovoltaic panel 3 is installed in place at all locations, and the plurality of snap-fit ​​portions 111 are evenly distributed on each side.

[0124] like Figures 4 to 6 As shown, to ensure a firm bond between the photovoltaic panel 3 and the backsheet frame 1, the photovoltaic panel 3 is further bonded to the backsheet frame 1 using an inner ring of sealant 6. The photovoltaic module 100 includes an energy storage battery pack 4, which, as previously described, is mounted on the backsheet frame 1 and located within the inner circumference of the inner ring of sealant 6. This further enhances the sealing and protection of the energy storage battery pack 4.

[0125] Similarly, to limit the inner ring sealant 6, the back panel frame 1 has a second sealant groove 15. The second sealant groove 15 has an upper opening, and the inner ring sealant 6 is filled in the second sealant groove 15 and at least partially exposed through the upper opening to bond with the photovoltaic panel 3. The second sealant groove 15 may have the same or similar structure as the first sealant groove 14, which is not limited here and will not be described in detail.

[0126] In this embodiment, as described above, the energy storage battery pack 4 includes a base shell 41, a back cover 42, and a cell assembly 44. The base shell 41 is formed on the back plate frame 1, and the back cover 42 is fitted onto the base shell 41. A receiving cavity 43 for accommodating the cell assembly 44 is formed between the base shell 41 and the back cover 42. The base shell 41 and the photovoltaic panel 3 are bonded and fixed together by at least one adhesive strip 9.

[0127] In this embodiment, the base shell 41 and the photovoltaic panel 3 are bonded and fixed together by multiple adhesive strips 9. The multiple adhesive strips 9 are distributed at intervals along the surface of the base shell 41. In this embodiment, the surface of the base shell 41 defines a positioning surface. In this embodiment, three adhesive strips 9 are used to bond and fix the photovoltaic panel 3 and the base shell 41. The three adhesive strips 9 are arranged relatively parallel and distributed at intervals along the positioning surface of the base shell 41.

[0128] At least some of the adjacent fixing adhesives 9 form an air-guiding gap 85, and the energy storage battery pack 4 has an exhaust channel, such as the aforementioned second exhaust channel, which connects the air-guiding gap 85 to the outside.

[0129] In this embodiment, as Figure 5 As shown, the photovoltaic panel 3 has electrode elements for conductive connection with the energy storage battery pack 4. The photovoltaic module 100 includes an electrode junction box 2 mounted on the energy storage battery pack 4 for housing the electrode elements. The electrode junction box 2 is filled with potting sealant, which at least covers the electrode elements and their connection points. Here, the electrode elements include positive and negative metal terminals and cable interfaces. The potting sealant completely covers the positive and negative metal terminals, solder joints, and cable interfaces, forming a seal without dead angles. In one embodiment, before potting, a nano-anti-flashover coating is sprayed onto the surface of the positive and negative metal sheets to block the electrochemical migration path of moisture. In another embodiment, the cable exiting the electrode junction box 2 is sealed by silicone compression mechanical extrusion.

[0130] Specifically, the base shell 41 has a mounting recess on its positioning surface, and the electrode junction box 2 is positioned within the mounting recess. In one embodiment, the upper end face of the electrode junction box 2 is substantially flush with the positioning surface of the base shell 41. In another embodiment, at least part of the upper end face of the electrode junction box 2 is exposed from the mounting recess and connected to at least one fixing adhesive strip 9 to make the positioning of the electrode junction box 2 more secure.

[0131] Specifically, the base shell 41 has a positioning hole 414 on its positioning surface, the battery cell assembly 44 has a positioning post 441, the positioning post 441 is connected to the positioning hole 414, and the positioning surface of the base shell 41 has a semi-annular protective edge constructed around the corresponding positioning hole 414.

[0132] In this embodiment, the sealant and / or fixing adhesive 9 is silicone. In other ways, polyurethane sealant or the like can also be used, and there is no limitation here.

[0133] In this embodiment, the back panel frame 1 has a plurality of lateral ribs 164. The lateral ribs 164 connect the first adhesive groove 14 and the frame 11 radially, and are spaced apart along the outer periphery of the first adhesive groove 14. The construction of the plurality of lateral ribs 164 enhances the lateral structural support strength between the first adhesive groove 14 and the frame, making the sealing of the edge sealant within the adhesive groove more secure and suppressing deformation and expansion of the edge sealant.

[0134] In this embodiment, as described above, the backplate frame 1 is provided with a first rib assembly 12, and the inner peripheral wall of the first adhesive groove 14 is connected to the first rib assembly 12 radially. The backplate frame 1 is provided with a first rib assembly 12 and a second rib assembly 13, and the outer peripheral wall of the second adhesive groove 15 is connected to the first rib assembly 12 radially. The second rib assembly 13 radially connects the inner peripheral wall of the second adhesive groove 15 to the outer wall of the energy storage battery pack 4. This further increases the radial support strength of the first adhesive groove 14 and the second adhesive groove 15, allowing the adhesive groove to more firmly limit the sealant inside and prevent the sealant from deforming and expanding. In addition, the construction of the first rib assembly 12 and the second rib assembly 13 also gives the backplate frame 1 sufficient structural strength to suppress surface bulging deformation. Optionally, the edge sealant and the inner ring sealant 6 are separated by the first rib assembly 12, and the first rib assembly 12 is distributed circumferentially in the first region 7, which has a venting structure, which will not be described in detail here.

[0135] like Figures 3 to 6 As shown, in this embodiment, to prevent rainwater from accumulating between the frame 11 and the edge seal, a photovoltaic module 100 is provided, including a back panel frame 1, a photovoltaic panel 3, an edge seal, and a drainage channel 16. Here, the edge seal can be the aforementioned edge sealant, or in other ways, it can be a pre-formed solid seal. The back panel frame 1 has a frame 11, and the photovoltaic panel 3 is assembled on the back panel frame 1 and placed within the frame 11. In one embodiment, the photovoltaic panel 3 is embedded within the frame 11, and the edge seal is circumferentially disposed between the photovoltaic panel 3 and the back panel frame 1. The drainage channel 16 is formed between the photovoltaic panel 3 and the back panel frame 1, and the drainage channel 16 is located radially between the frame 11 and the edge seal. The drainage channel 16 has a drainage hole 167 for draining water to the outside.

[0136] In this embodiment, by constructing a drainage groove 16 between the frame 11 and the edge seal, rainwater or dew and other external moisture that seeps into the edge seal along the edge seam, i.e., the installation gap between the frame 11 and the edge of the photovoltaic panel 3, can be received and discharged to the outside in a timely manner through the drainage hole 167, preventing rainwater from accumulating on the side of the edge seal and generating moisture that corrodes the seal after being exposed to high temperature, or from leaking into the inner cavity of the photovoltaic module 100.

[0137] In one embodiment, the drainage channel 16 is configured as an annular drainage channel, which surrounds the edge seal. Specifically, in this embodiment, the back plate frame 1 is configured as a rectangular frame, and the drainage channel 16 is configured as a loop-shaped channel enclosed by the frame 11 and the edge seal.

[0138] In another embodiment, the drainage channel 16 may also be configured as a U-shaped channel or a straight channel, as described above, and will not be elaborated here.

[0139] In this embodiment, the edge seal is made of edge sealant, that is, as shown in the example. Figure 3 and Figure 5 In one embodiment of the outer ring sealant 5 shown, the back panel frame 1 has a first sealant groove 14 with an upper opening. The edge sealant is filled in the first sealant groove 14 and at least partially exposed through the upper opening of the first sealant groove 14 and bonded to the photovoltaic panel 3.

[0140] In this embodiment, the frame 11 defines an installation port, and the photovoltaic panel 3 is assembled onto the back panel frame 1 through the installation port.

[0141] In this embodiment, the frame 11 has a snap-fit ​​part 111, which is operablely pressed against the upper surface of the photovoltaic panel 3 while the photovoltaic panel 3 is assembled onto the back panel frame 1. Here, the snap-fit ​​part 111 can have various structural forms, such as the rotating snap-fit ​​part 111 and the elastic snap-fit ​​part 111 provided above, etc., which will not be listed here.

[0142] Here, when the snap-fit ​​part 111 is an elastic snap-fit ​​part 111 integrally formed on the frame 11, the drainage hole 167 is formed on the frame 11 and is arranged below the snap-fit ​​part 111 along the snap-fit ​​direction. In this way, on the one hand, the drainage hole 167 structure can timely drain the accumulated water in the drainage groove 16 to the outside, and on the other hand, the arrangement of the drainage hole 167 appropriately weakens the structural rigidity of the frame at the snap-fit ​​part 111, making it easier to place the photovoltaic panel 3 into or remove it from the frame 11 through elastic deformation.

[0143] In this embodiment, as Figure 4 and Figure 6 As shown, the frame 11 has a stepped portion, and the photovoltaic panel 3 abuts against the stepped portion through the mounting port. The drainage groove 16 is located between the stepped portion and the edge seal. Specifically, after assembly, the photovoltaic panel 3 abuts against the stepped portion and the snap-fit ​​portion 111, and the edge seal abuts against the first adhesive groove 14 and the photovoltaic panel 3.

[0144] In this embodiment, a plurality of lateral ribs 164 are arranged in the drainage channel 16. The lateral ribs 164 are respectively connected to the first glue channel 14 and the frame 11 in the radial direction. The plurality of lateral ribs 164 are distributed at intervals in the drainage channel 16 and divide the drainage channel 16 into a plurality of water accumulation inner channels.

[0145] As mentioned above, the construction of multiple lateral ribs 164 enhances the structural support strength between the first glue groove 14 and the frame 11, making the sealing of the inner edge of the glue groove more secure and reducing the probability of thermal deformation of the frame 11. In addition, the multiple lateral ribs 164 divide the drainage groove 16 into multiple water accumulation grooves. After water enters the drainage groove 16, it is separated by multiple water accumulation grooves, breaking the surface tension of the water flow, so that the water flow can be discharged more smoothly from the drain hole 167. In addition, the water flow accumulated through the water accumulation grooves can wash the inner wall of the drainage groove 16, preventing dust accumulation on the inner wall.

[0146] In this embodiment, as Figure 13 and Figure 14 As shown, a drainage channel 166 is formed between the top of the lateral rib 164 and the photovoltaic panel 3, and the drainage channel 166 connects the water collection tanks and the drainage holes 167. Thus, water in each water collection tank can be discharged promptly from the drainage holes 167 through the drainage channel 166. In one embodiment, the drainage channel 166 is provided by the installation spacing between the photovoltaic panel 3 and the lateral rib 164.

[0147] In one scenario, the shape of the drain hole 167 may be configured as a circular hole or as a square hole as described in this embodiment, without limitation.

[0148] In this embodiment, the surface of the back panel frame 1 protrudes upward to form an annular inner baffle 141 and an outer baffle 142. The first glue groove 14 is formed by the inner baffle 141, the outer baffle 142 and the back panel frame 1 between them. The drainage groove 16 is formed by the outer baffle 142, the frame 11 and the back panel frame 1 between them.

[0149] In this embodiment, the photovoltaic module 100 further includes an energy storage battery pack 4 and an internal seal. The energy storage battery pack 4 is mounted on the back panel frame 1, and the internal seal is disposed between the photovoltaic panel 3 and the back panel frame 1. In the radial direction, the internal seal is located between the edge seal and the energy storage battery pack 4.

[0150] In one embodiment, the internal seal is made of sealant, such as... Figure 3 The inner ring sealant 6 shown has a second sealant groove 15 on the back plate frame 1. The second sealant groove 15 has an upper opening. The edge sealant is filled in the second sealant groove 15 and at least partially exposed through the upper opening of the second sealant groove 15 and is bonded to the photovoltaic panel 3.

[0151] In this embodiment, as Figures 5 to 6As shown, the frame 11 protrudes radially into the frame to form an extension 112 on the inner wall of the frame 11. The photovoltaic panel 3 has a relief portion to avoid the extension 112. The extension 112 has an extension surface, which is used for visual marking, such as for silkscreening text logos or other visual positioning marks.

[0152] Meanwhile, the frame 11 protrudes radially into the frame to form a recess on the outer wall of the frame 11, and a reinforcing rib is disposed in the recess. The drainage hole 167 is formed on the back plate frame 1 between the edge seal and the protruding portion 112.

[0153] In this embodiment, as Figure 6 As shown, the drainage channel 16 has at least one extension section extending from the upper edge to the lower edge of the photovoltaic module 100. The middle part of the extension section has an upper bend portion 161 formed by bending inward at a first angle and a transition portion 163 extending linearly downward from the end of the upper bend portion 161. At least one drainage hole 167 is formed on the transition portion 163.

[0154] In this embodiment, during drainage, the water flow from the upper bend 161 to the middle transition 163 will generate a stable acceleration. Using this acceleration, the water flow here can be discharged from the drain hole 167 at the maximum flow rate. In the case of use where there is mud and sand in the water, the accelerated water flow here can flush the mud and sand out from the drain hole 167. Compared with a straight channel, it can reduce sedimentation and blockage.

[0155] In this embodiment, the protruding portion 112 is disposed in the longitudinal middle of the frame 11. The protruding portion 112 has a trapezoidal structure. Radially, the lower bottom of the protruding portion 112 is formed on the frame 11, and the upper bottom is connected to the drainage groove 16. Longitudinally, the protruding portion 112 has an upper waist side and a lower waist side, with the upper waist side located above the lower waist side. The upper bending portion 161 is formed between the first glue groove 14 and the upper waist side of the protruding portion 112. Optionally, the first glue groove 14 has an upper bending section, and the upper bending portion 161 is formed between the upper bending section of the first glue groove 14 and the upper waist side of the protruding portion 112. The transition portion 163 is formed between the upper bottom and the first glue groove 14. Optionally, the first glue groove 14 has a transition section, which is connected to the upper bending section. Optionally, the transition section is a linear section.

[0156] In this embodiment, the middle portion of the extension section has a downward bend 162 formed by bending the end of the transition portion 163 outward at a second angle. The downward bend 162 is formed between the first adhesive groove 14 and the lower waist side of the protruding extension 112. Optionally, the first adhesive groove 14 has a downward bend section, and the downward bend 162 is formed between the downward bend section and the lower waist side of the protruding extension 112.

[0157] When transitioning from the upper bending section to the middle transition section of the first adhesive groove 14, the sealant or sealing element in the first adhesive groove 14 deforms rapidly and absorbs a certain amount of stress. Here, the transition section is constructed as a linear section to prevent stress from being transmitted from the sealant installation position to both sides of the first adhesive groove 14. The reverse deformation of the lower bending section can at least offset some of the residual stress.

[0158] Optionally, the first angle and / or the second angle is 120° to 150°.

[0159] Optionally, the first angle is equivalent to the second angle.

[0160] In this embodiment, a photovoltaic module 100 is also provided, which aims to solve the problems of limited installation methods and application scenarios of solar photovoltaic modules in the prior art. It not only enables photovoltaic modules to be installed on antenna pipelines, but also to be installed on the ground without changing the mounting bracket, thus expanding the application scenarios of photovoltaic modules and improving installation flexibility and adaptability.

[0161] like Figure 1 , Figure 2 As shown, in this embodiment, the photovoltaic module 100 can be selectively positioned on a cylindrical or planar mounting surface. Specifically, the photovoltaic module 100 includes a backplate frame 1, a photovoltaic panel 3, and a support member 202. The photovoltaic panel 3 is assembled on the backplate frame 1. One end of the support member 202 is operably connected to the backplate frame 1, and the other end has a connecting wall 2021 with a U-shaped cross-section. The concave portion of the connecting wall 2021 is adapted to hug and operably connect to the cylindrical mounting surface, and the support leg portion is adapted to be operably connected to the planar mounting surface.

[0162] In this embodiment, by constructing a connecting wall 2021 with a U-shaped cross-section on the supporting member 202, when the photovoltaic module 100 needs to be installed on a cylindrical mounting surface, such as the antenna body 200 of an RTK fixed station antenna, the concave portion can be clamped and operably connected to the cylindrical mounting surface. Here, the operable connection is, for example, through fastener connection. When the photovoltaic module 100 needs to be installed on a flat mounting surface, such as the ground, the support leg can be operably connected to the flat mounting surface. That is to say, this embodiment, through clever shape modification, forms at least two mounting parts on a connecting wall 2021, one for connecting the cylindrical mounting surface and the other for connecting the flat mounting surface. The two mounting parts do not interfere with each other during use, so that the photovoltaic module 100 can be installed on two types of mounting surfaces at the same time without the need to replace the supporting member 202, making the photovoltaic module 100 more flexible to use and easier to install.

[0163] like Figure 2 As shown, in one scenario, the connecting wall 2021 is integrally formed; in another scenario, the concave portion of the connecting wall 2021 is formed by bending. This simplifies the manufacturing process of the supporting member 202 and further reduces manufacturing costs. In one scenario, the concave portion of the connecting wall 2021 is C-shaped; in another scenario, the concave portion of the connecting wall 2021 is trapezoidal or U-shaped, and no limitation is imposed here.

[0164] In this embodiment, a first connecting hole 2022 is formed in the recess of the connecting wall 2021, and a first connector is inserted into the first connecting hole 2022 to connect the support member 202 and the column mounting surface.

[0165] In one scenario, the cylindrical mounting surface has a first mating hole, a first connecting hole 2022 and / or a first nut welded to the opening of the first mating hole, and a first connecting member is a first bolt. The first connecting member passes through the first connecting hole and the first mating hole and is screwed into the first nut to realize the connection and fixation between the support member 202 and the cylindrical mounting surface, thereby realizing the installation and fixation of the photovoltaic module 100.

[0166] In one scenario, a first connector is provided on the cylindrical mounting surface, such as a first bolt welded to the cylindrical mounting surface, and a first connecting hole 2022 passes through the first connector and screws a nut onto the first connector to achieve a fastening connection.

[0167] In one scenario, the first connector is connected to the first connecting hole 2022, and the first connector is snapped into and fixed to the cylindrical mounting surface.

[0168] In this embodiment, a second connecting hole 2023 is formed on the support leg of the connecting wall 2021, and a second connector is inserted into the second connecting hole 2023 to connect the support member 202 with the planar mounting surface.

[0169] In one scenario, the planar mounting surface has a second mating hole, a second connecting hole 2023 and / or a second nut is welded to the opening of the second mating hole, the second connector is a second bolt, the second connector passes through the second connecting hole and the second mating hole, and is screwed into the second nut, thereby realizing the connection and fixation between the support member 202 and the planar mounting surface, and thus realizing the installation and fixation of the photovoltaic module 100.

[0170] In one scenario, a second connector is provided on the flat mounting surface, such as a second bolt welded to the flat mounting surface, and a second connecting hole 2023 passes through the second connector and screws a nut onto the second connector to achieve a fastening connection.

[0171] In this embodiment, the back panel frame 1 is operably connected to the support member 202 in a manner that allows it to rotate about a predetermined axis. In one embodiment, operability at least means that the back panel frame 1 can be rotated relative to the support member 202 by an angle to allow the photovoltaic panel 3 to adapt to changes in the solar altitude angle.

[0172] In this embodiment, one of the support member 202 and the back plate frame 1 has a plurality of anti-rotation holes 2026, which are spaced apart on a predetermined circumference with the predetermined axis as the center. The other of the support member 202 and the back plate frame 1 is provided with a limiting member, which is connected to the corresponding anti-rotation hole 2026 to limit the rotation angle of the back plate frame 1 relative to the support member 202.

[0173] Here, the anti-rotation hole 2026 is a circular hole, and the plurality of anti-rotation holes 2026 are distributed at equal intervals on a specified circumference with the specified axis as the center.

[0174] In one embodiment, the limiting member is, for example, a limiting bolt, which is screwed into the anti-rotation hole 2026 to limit the rotation angle of the back plate frame 1 relative to the support member 202. In another embodiment, the support member 202 and the back plate frame 1 have an anti-rotation engagement hole, and the limiting member is inserted into the anti-rotation engagement hole and the corresponding anti-rotation hole 2026 and locked in place by a nut to limit the rotation angle of the back plate frame 1 relative to the support member 202.

[0175] In one embodiment, one of the back plate frame 1 and the support member 202 has a pivot connection hole, and the other has a pivot engagement hole. A single-headed bolt inserted into the pivot connection hole and the pivot engagement hole serves as the central pivot for relative rotation between the two, and the axial position of the pivot is defined by a nut.

[0176] In this embodiment, the support member 202 has a pair of support arms 2025 arranged opposite to each other. In one embodiment, the support arms 2025 are integrally formed and connected to the connecting wall 2021. Specifically, the support arms 2025 have a first end and a second end. The first end is formed on the connecting wall 2021, and the second end is operably connected to the back plate frame 1. The pair of support arms 2025 are arranged to gradually extend in an inclined direction from the first end to the second end, so that the pair of support arms 2025, the connecting wall 2021 and the back plate frame 1 form a structure similar to a spatial triangular truss, which enhances the support stability.

[0177] In one embodiment, the photovoltaic module 1 includes a connecting member 201 mounted on the backsheet frame 1. The connecting member 201 is detachably connected to the support member 202, for example, by means of threaded fasteners or by means of snap-fit ​​fasteners, without limitation.

[0178] In this embodiment, the connecting member 201 includes a connecting shell 2011 and a pair of connecting ears 2012 disposed on the connecting shell 2011. The connecting shell 2011 is detachably connected to the back plate frame 1, and the connecting ears 2012 are detachably connected to the support member 202. Specifically, the back plate frame 1 has an annular mounting protrusion on its back. The connecting shell 2011 covers the mounting protrusion and is locked and fixed with fasteners. Specifically, the mounting protrusion has a clearance hole for avoiding the installation of the energy storage battery pack 4. The energy storage battery pack 4 protrudes rearward from the clearance hole. Sufficient space is formed between the pair of support arms 2025 and the connecting wall 2021 for disassembly and assembly of the connecting member 201 and the back plate frame 1, the connecting member 201 and the support member 202 and / or the energy storage battery pack 4.

[0179] In one embodiment, the connecting member 201 is an integrally formed part, wherein the integral forming is, for example, molding, welding, or sheet metal forming.

[0180] In one embodiment, the connecting ear 2012 extends rearward from the surface of the connecting shell 2011. When the connecting ear 2012 is in the detached state, it also serves as a back support to support the photovoltaic module 100 on the flat mounting surface, further expanding the application scenarios of the photovoltaic module 100 and improving the flexibility and convenience of the photovoltaic module 100 in use.

[0181] In this embodiment, the photovoltaic module 100 includes an energy storage battery pack 4, which is mounted on the backsheet frame 1. The energy storage battery pack 4 protrudes rearward from the surface of the backsheet frame 1. The connecting member 201 has a clearance hole to avoid the energy storage battery pack 4. The connecting lug 2012 is configured to extend rearward beyond the energy storage battery pack 4. In the event of an accidental drop or fall of the photovoltaic module 100, the hard contact surface can be prevented from directly impacting the energy storage battery pack 4, thereby increasing the safety and reliability of the photovoltaic module 100 during use.

[0182] In this embodiment, the support member 202 is an integrally formed part, which can be formed by molding, welding or sheet metal forming. In this way, the structural strength of the support member 202 can be guaranteed and the manufacturing process is simple.

[0184] In this embodiment, the cylindrical mounting surface may, in one embodiment, be provided by the antenna body 200 of the RTK fixed station antenna.

[0185] In summary, through the construction of the support member 202 in this embodiment, the photovoltaic module 100 can be installed on the antenna body 200 of the RTK fixed station antenna, or it can be installed on the ground without replacing the support member 202, thus expanding the application scenarios of the photovoltaic module 100, as well as its installation flexibility and adaptability.
