Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of storage boxes, in particular to a storage box for a solar panel junction box for a sunroom and a solar panel installation structure. Background Art
[0002] The top surface of a traditional sunroom is mostly made of glass. With the continuous development of technology and the deepening of the concept of energy conservation and emission reduction, the market demand for eco-friendly sunrooms is constantly increasing. In order to respond to the national call for energy conservation and emission reduction and meet the diverse needs of the market, the existing pure glass sunrooms are improved, and a solar panel sunroom is developed. A part of the glass is replaced by solar panels as the roof of the sunroom. The solar panels can provide electric energy for the sunroom, which can not only save electricity bills but also be more beneficial to environmental protection.
[0003] The existing solar panel sunroom uses traditional solar panels as the roof. On the backlight side of the solar panels, the series and parallel connections between the solar panels are realized through solar panel junction boxes. To prevent the solar junction boxes from falling off and avoid drilling holes in the solar panels and damaging the solar panels, in practice, colloids are often used to bond the solar panel junction boxes to the backlight side of the solar panels.
[0004] Since the solar panel junction boxes in the existing solar panel sunrooms are exposed, when the colloids age after the sunroom has been used for a long time, the solar panel junction boxes are likely to fall off, resulting in the disconnection of the connections between the solar panels. This leads to a decrease in the power generation of the solar panels, and at the same time, it may cause safety accidents such as high temperature and short circuit inside the photovoltaic modules, and even trigger a fire. Summary of the Utility Model
[0005] An object of the utility model is to provide a storage box for a solar panel junction box for a sunroom and a solar panel installation structure, which solves the problem of short circuit of the junction box and safety accidents caused by the falling of the existing solar panel junction box.
[0006] The storage box for the solar panel junction box for the sunroom is installed on the backlight side of the solar panel. The storage box is annular and includes a plurality of monomer boxes spliced in sequence along the circumferential direction of the sunroom support beam. Each monomer box includes a bottom plate, a first side plate and a second side plate respectively connected to two side edges in the width direction of the bottom plate. The first side plate is attached to the support beam, and a hanging portion for hanging the storage box on the sunroom support beam is arranged on the first side plate. The solar panel, the second side plate, the bottom plate and the first side plate jointly define an accommodation space for accommodating the solar panel junction box, and the second side plate abuts against the solar panel.
[0007] Further, the hanging portion is formed by bending the first side plate away from the bottom plate and towards the support beam.
[0008] Further, the distance between the overlapping point of the second side plate and the solar panel and the support beam is greater than a preset value.
[0009] Further, the second side plate and the solar panel are adhesively bonded by a colloid.
[0010] In particular, the present utility model further provides a solar panel mounting structure for a sunroom, including the solar panel junction box storage box for the sunroom described above.
[0011] Further, the solar panel mounting structure further includes:
[0012] A support beam, located on the backlight side of the solar panel and supporting the solar panel, a hanging groove is provided on the side wall of the support beam perpendicular to the solar panel, and the hanging portion of the storage box is connected to the hanging groove, so that the storage box is hung on the support beam;
[0013] A pressing mechanism, installed on the light-facing side of the solar panel, and used to fix and press the solar panel on the support beam.
[0014] Further, two solar panels are horizontally overlapped on both sides of one support beam in the width direction, the two solar panels are arranged at intervals, and the two opposite side walls of the two solar panels and the top surface of the support beam jointly define a groove. While the pressing mechanism presses the two solar panels on the same support beam, it is connected to the support beam through the groove, so that the solar panel is fixed on the support beam.
[0015] Further, the pressing mechanism includes a pressing plate, a through hole is provided in the center of the pressing plate, a screw passes through the through hole and inserts into the groove, and is connected to a screw hole preset on the support beam.
[0016] Further, the pressing mechanism further includes an airtight strip connected to the side of the pressing plate close to the solar panel, and the airtight strip is arranged along the circumference of the pressing plate.
[0017] Further, a cover plate covering the pressing mechanism is provided on the pressing mechanism.
[0018] The beneficial effects of the present utility model are:
[0019] 1. By installing the solar panel junction box in the storage box, the exposure of the solar panel junction box is avoided. When the colloid used to bond the solar panel and the junction box ages and causes the junction box to fall off, the junction box falls into the storage box, preventing the wires in the junction box from being short-circuited under the gravitational pull of the storage box, which has an adverse impact on the safe use of the solar panel. At the same time, the storage box can also support the solar panel from the backlight side of the solar panel, making the installation of the solar panel more firm.
[0020] 2. By installing a pressing mechanism on the light-receiving side of the solar panel, the solar panel is firmly installed on the support beam.
[0021] 3. An airtight strip is installed on the abutting part of the pressing mechanism to prevent damage to the solar panel when the pressing mechanism presses the solar panel, and at the same time prevent rainwater from corroding the screws under the pressing plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] To make the above objects, features, and advantages of the present application more obvious and understandable, the following describes the specific embodiments of the present application in detail with reference to the drawings. It can be understood that the specific embodiments described herein are only for explaining the present application and not for limiting the present application. In addition, it should be noted that for the sake of description, only parts related to the present application are shown in the drawings instead of all the structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.
[0029] The term "comprising" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.
[0030] Reference to "an embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0031] As Figure 1 shown, the solar panel junction box storage box 1 (abbreviated as "storage box") for a sunroom of the present utility model is used to store the solar panel junction box 6 (abbreviated as "junction box") installed on the backlight side of the solar panel 2. To avoid the influence of the external environment on the junction box 6, the junction box 6 is often fixed on the backlight side of the solar panel 2. Therefore, the storage box 1 of the present utility model is installed on the backlight side of the solar panel 2.
[0032] The junction box 6 is used to connect a plurality of mutually spliced solar panels 2. In order to store adjacent junction boxes 6 in a storage box 1 at one time. As Figure 3 shown, the storage box 1 of the present utility model is set in a ring shape. The storage box 1 includes a plurality of single boxes 4 spliced in sequence along the circumference of the sunroom support beam 3 as Figure 2 shown. During the construction process, through the assembly between the plurality of single boxes 4, it is more convenient to install the storage box 1 on the circumference of the support beam 3. In one embodiment, as Figure 2 shown, the single box 4 is strip-shaped. After chamfering the two ends of the strip-shaped single box 4 along the length direction and splicing them in sequence, the storage box 1 is connected into a square ring shape as Figure 3 shown. In other embodiments, the single box 4 can also be arc-shaped, and a plurality of arc-shaped single boxes 4 are sequentially connected into a circular storage box 1. The sunroom support beam 3 is defined in the center of the circular storage box 1.
[0033] Each monomer box 4 includes a bottom plate 41, a first side plate 42 and a second side plate 43 respectively connected to two side edges in the width direction of the bottom plate 41. The first side plate 42 is attached to the support beam 3. A hanging portion 5 is provided on the first side plate 42, and the storage box 1 is hung on the sunroom support beam 3 through the hanging portion 5. In one embodiment, the hanging portion 5 is formed by bending the first side plate 42 away from the bottom plate 41 towards the support beam 3. In other embodiments, the hanging portion 5 is a hook formed by bending a long strip plate, and the hanging portions 5 are arranged at intervals along the length direction of the first side plate 42. After the storage box 1 is hung on the sunroom support beam 3, the second side plate 43 abuts against the solar panel 2. At this time, the solar panel 2, the bottom plate 41, the first side plate 42 and the second side plate 43 jointly define a receiving cavity for installing the junction box 6.
[0034] In one embodiment, the distance between the connection point of the second side plate 43 and the solar panel 2 and the support beam 3 is greater than a preset value. When the solar panel 2 drops downward, the storage box 1 can better abut against the solar panel 2, improving the safety after the installation of the solar panel 2.
[0035] By installing the solar panel junction box 6 in the storage box 1, the exposure of the junction box 6 of the solar panel 2 is avoided. When the colloid used to bond the solar panel 2 and the junction box 6 ages and causes the junction box 6 to fall off, the junction box 6 falls into the storage box 1, preventing the wires in the junction box 6 from being short-circuited under the gravitational pull of the junction box 6, which has an adverse impact on the safety of the use of the solar panel 2. At the same time, the storage box 1 can also abut against the solar panel 2 from the backlight side of the solar panel 2, making the installation of the solar panel 2 more firm.
[0036] In particular, the present utility model also provides a solar panel 2 installation structure for a sunroom, including a support beam 3, a pressing mechanism 7 and the above-mentioned storage box 1. As Figure 1 shown, the height of the support beam 3 is greater than the width of the support beam 3. Support columns (not shown) are provided under the support beam 3 and abut against the support beam. The support beam 3 is located on the backlight side of the solar panel 2 and supports the solar panel 2. Hanging grooves 8 are provided on the side walls of the existing support beam 3 perpendicular to the solar panel 2, and the hanging portions 5 of the storage box 1 are connected to the hanging grooves 8, so that the storage box 1 is hung on the support beam 3. The pressing mechanism 7 is installed on the light-receiving side of the solar panel 2 and presses the solar panel 2 to fix the solar panel 2 on the support beam 3.
[0037] By hanging the storage box 1 in the hanging groove 8 of the support beam 3, when it is necessary to repair the junction box 6 in the storage box 1, the installation and disassembly of the storage box 1 are made more convenient. Through the solar panel installation structure of the present utility model, not only the solar panel 2 is installed more firmly, but also when installing the storage box 1, the existing hanging groove 8 on the existing support beam 3 is utilized, and there is no need to process the support beam 3 separately. The existing support beam 3 structure can be directly adopted, reducing the production cost and the use threshold.
[0038] In one embodiment, two solar panels 2 are horizontally lapped on both sides of a support beam 3 in the width direction. The two solar panels are arranged at intervals. The two opposite side walls of the two solar panels 2 and the top surface of the support beam 3 jointly define a groove 10. While the pressing mechanism 7 presses the adjacent two solar panels 2, the solar panels 2 are fixed on the support beam 3 through the connection of the groove 10 and the support beam 3. To prevent rainwater from entering the sunroom through the groove 10, sealant 11 can be injected into the groove 10, or foam filling can be used.
[0039] In one embodiment, the pressing mechanism 7 includes a pressing plate 71. A through hole 73 is provided in the center of the pressing plate 71. After the screw 74 passes through the through hole 73, it is inserted into the groove 10 and connected to a screw hole preset on the support beam 3, so that the solar panel 2 is fixed on the support beam 3. Directly using the pressing plate for fixation not only simplifies the construction process but also makes the material taking more convenient.
[0040] In order to prevent external rainwater from extending under the pressing plate through the gap between the pressing plate and the solar panel, resulting in the corrosion of the screw 74 by rainwater, and at the same time to prevent the pressing mechanism 7 from causing damage to the solar panel 2 when pressing the solar panel 2. In one embodiment, the pressing mechanism 7 further includes an airtight strip 75 connected to the side of the pressing plate 71 close to the solar panel 2 and arranged along the circumference of the pressing plate 71. Through the sealing effect of the airtight strip 75, moisture is prevented from seeping along the gap between the pressing plate 71 and the solar panel 2 and corroding the screw 74. At the same time, when the pressing plate 71 presses the solar panel 2, the airtight strip 75 also plays a buffering role, preventing the solar panel 2 from being damaged by pressure and improving the service life of the solar panel 2. There are various connection methods between the airtight strip 75 and the pressing plate 71: First, a holding portion 72 can be arranged along the circumference of the pressing plate 71 on the side of the pressing plate 71 close to the solar panel 2. A connection groove is provided on the holding portion 72, and the airtight strip 75 is provided with a protrusion that can be engaged with the connection groove. The protrusion is limited in the connection groove, so that the airtight strip 75 is connected to the pressing plate 71. Or a connection groove can be provided on the airtight strip 75, and the holding portion 72 is limited in the connection groove, so that the airtight strip 75 is connected to the pressing plate 71; Second, the airtight strip 75 and the pressing plate 71 can also be directly bonded through a colloid.
[0041] In the first connection mode, the airtight strip 75 is detachably connected to the pressing plate 71, which can be reused, reducing the use and installation costs. In the second connection mode, the connection between the pressing plate 71 and the airtight strip 75 is more firm, and at the same time, it is easy to process and produce, reducing the processing difficulty and production cost. The above two methods can be flexibly selected according to the actual situation. Other methods that can connect the airtight strip 75 and the pressing plate 71 all fall within the protection scope of the present utility model and will not be elaborated herein.
[0042] At the same time, since the solar panel 2 is arranged in an outdoor environment, the screws 74 on the pressing mechanism 7 are corroded by rainwater. Therefore, a cover plate 9 is arranged on the pressing mechanism 7 to cover the pressing mechanism 7. In one embodiment, the pressing plate 71 is provided with a protrusion, and the cover plate 9 covers the pressing mechanism 7, and the protrusion abuts against the inner wall of the cover plate 9 to fix the cover plate 9 on the pressing mechanism 7. By providing the cover plate 9, the exposed part of the screw 74 on the pressing mechanism 7 is prevented from being corroded due to contact with rainwater, affecting the service life of the screw 74, and further improving the durability of the solar panel installation structure.
[0043] In order to press the solar panel 2 more firmly. As Figure 4 shown, in other embodiments, the pressing mechanism 7 can also be arranged at the intersection of two support beams 3, and the pressing mechanism 7 presses one corner of each of the four solar panels 2 located at the intersection at the same time. The screw 74 is inserted into the screw hole preset at the intersection of the support beams 3. The integrity of the entire solar panel 2 installation structure is enhanced, making the installation of the solar panel 2 more firm.
[0044] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
